Re: WTD: Filter capacitors for 8662A PSU
One thing to watch out for with modern replacements is the ripple current rating - one benefit of the large Compulytics was that they could dissipate more power. Modern replacements may have a lower ESR which can mitigate this, but it is something that needs to be taken into account. The large screws used to mount the capacitors to the board also served as a path to dissipate any generated heat.? Of course the equipment -especially with HP- was not only typically engineered with a large margin for error, but also designed to be operated 24/7 in server racks with a much higher ambient temperature which eases the requirements on modern replacements .

Re: How to find patents for HP equipment
开云体育Hi Pete:There are a number of ways. In general there are two search engines.? The USPTO and Google. The good news is that Google has used Optical Character Recognition (OCR) and so you can search all of their data base for any word anywhere. The bad news is that Google has used Optical Character Recognition which has many mistakes, so there are odds associated with any search. - this is the basic patent number search and for United States patent number the first two characters need to be US. At the bottom of that page there's a link to the Advanced Search where you have a lot more options. The Google patent result pages can be trimmed back so that they end with the patent number, a very convenient situation. The USPTO has a number of web pages for searching.? But they use .tif format for the patents, i.e. no OCR and the searches can only be done on the fields they have digitized. This is the patent number search (good for getting class numbers): This is the Quick search:? Notice the select years drop down box.? When you select 1976 to present there are many more fields available to search. When 1790 to present there are fewer fields available.? There was a patent office fire in 1836 so some patents are no longer available. The URL for a search result is not permanent nor is the result of a patent number search. ALL patents are issued on a Tuesday.? So? you can check? a patent date using a Calendar to confirm the patent is on a Tuesday.? If the date is not on a Tuesday there's a typo. My web pages are filled with patents on all kinds of things including HP instruments.? Here's an old list: And a general discussion: I used to visit the Sunnyvale, California patent office and it turns out they are the only one where the patents are filed by Class/Sub-class numbers.? NOT in patent number order. This allows for easy searching once you know the class numbers for the general area. If you let me know more specifics I may be able to help. -- Have Fun, Brooke Clarke, N6GCE axioms: 1. The extent to which you can fix or improve something will be limited by how well you understand how it works. 2. Everybody, with no exceptions, holds false beliefs. |

A classic example of trade secret protection is the formula for Coke. Patents expire, but trade secret protection lasts as long as the secret can be kept.

?? Also, Some companies relied more on trade secret protection. Eastman Kodak did this for many years because there is no time limit on it. They began to rely more on patents when the rate of discovery of new products became rapid enough for a patent to last through the market life. A trade secret can protect one against having a product design stolen but not against independent discovery. ?? Patent law seems to be extremely convoluted although it still not as bad as copyright law. On 2/21/2022 3:38 PM, Francesco Ledda via groups.io wrote:

开云体育Having worked as a design engineer I can tell you a little bit about how the process worked at least at the company I worked at , usually it’s the design engineer who files what is called a patent disclosure ,? this contains normally a outline of the idea , drawings and a brief explanation , this info goes to the legal department where it is examined by a patent lawyer for merit , if the legal folks say that the idea has merit than they draft a formal patent application and during the process request sometimes additional information from the engineer who wrote the initial disclosure and then file the application with the USPTO , this is usually done early in the design process so the provisional patent usually is issued long before the design goes into pre-production or released for final production ?

Trivia: My career was with DEC, then with HP and HPE. DEC was "stingy" about spending money for patents. In the late 80's I submitted a Disclosure as an employee of Manufacturing. DEC said basically "good idea, but in Manufacturing we can just keep it a secret, so no need for a patent." But HP was very generous with patents. Simply submitting the disclosure paperwork paid the employee $100. If the patent was actually granted, they paid another $1000. I got two in my career (8184982 and 8648568) - the second one took 4 years until it was granted (but it was submitted first). Pete |
RPG 5060-9444 (conversion LAMP to LED)
开云体育Hi, just a story about HP/Agilent 5060-9444 5 VDC Rotary Pulse Generator RPG +, replace LAMP by LED. ? ? I had the opportunity to get an 8350B with an 83595A (0.01-26.5GHz). This device had to be stored for a few years. In short, I had to partially disassemble it to remove dust and some traces of corrosion. I changed the battery of course and fixed several problems like the front panel which was partially working. I had to do a complete alignment, now everything is OK. The 83595A seemed to be in better shape, but the RPG was not working. I removed it from the module and opened it up...after examining the circuit, it was easy to see that the lamp was burned out. I studied the module and how it worked, so I tried a repair by replacing the lamp with an LED. ? I found that this little module was quite ingenious. All the parts are on the top of the PCB and underneath 2 photo detectors in a dark room, where there are two plastic sheets in the shape of a circle, a hole followed by another one on top translucent. A small metal piece bent at 45 degrees, serves as a support for the lamp but also as a reflector to direct the light through two tunnels to the photo detectors. The two tunnels have screws allowing them to partially obstruct the light, allowing the two circuits to be balanced. If the light intensity is sufficient, this will trigger the gate 7413 (Schmitt Trigger). When the light levels are balanced by the screws, the duration of the pulses, for a constant speed, should be approximately the same. ? Using an LED recovered from a defective LED bulb, which was the perfect size to fit and fill the rectangular area where the bulb was located, I was able to determine the LED current for minimum operation of the RPG. The currents were 7mA for one side, and 11 mA for the other. I tested up to 30 mA for proper operation. I reduced it to 20mA, found the resistance needed for this current in the LED at 5V. The LED dropped 2.721V. I balanced the circuit with the screws and closed everything. Now the RPG of my 83595A works correctly. I will just have to make the necessary alignments for optimal operation. ? ? -Yves |
