Title: Sprung holder for electronic component cooler - has integral plastics body with coaxial guide for holder and cooler displacement
Inventor: BURGER RUDOLF
IPC: H01L23/40
Filed: 1991-08-30
Abstract: The cooler (4) holder (3) is of coaxial type and the two members are axially displaceable and mutually guided.

Title: Asynchronous transfer mode cell delay circuit for ISDN - multiplexes input signal cells with generated dummy cells to allow for propagation time through shift register
Inventor: NAKAJIMA HIDEKI
IPC: H04L12/70
Filed: 1992-04-13
Abstract: Dummy cells are produced at controllable intervals by a generator (1) whose output is multiplexed (3) with that of a first filter (2) extracting only cells requiring delay from the input signal. The multiplexed cells are delayed (4) in a shift register and forwarded to a second filter (5) which removes the dummy cells. This filter may be omitted if the generator (1) itself produces idle cells. The dummy cells allow delay to be implemented without interruption of duplex transmission. ADVANTAGE - Two-way data transmission is facilitated with different delays imposed on cells input in constant time intervals.

Patent DE-4238011-A1 (DE)
Inventor: SADJINA HEINZ DIPL ING
IPC: B01F23/10
Filed: 1992-11-11
Abstract: The invention relates to a method for mixing two or more gases in a controlled manner, the flows of the unmixed gases being adjusted in a suitable manner for the mixture to be produced. In so doing, the mixture ratio is intended to be very accurately maintained without the use of a buffer container - even under dynamic conditions. Given the stipulation that the gas with the greatest proportion represents the master gas and the further gas(es) is/are the slave(s), the controlled mixing is so carried out that the control sequence is that the quotient Qi is formed from the actual flows of the master gas and slave gas(es), the quotient Qs of the desired flows is formed in parallel, the difference of these quotients is formed and the result of this subtraction is added to the desired flow of the master gas (= command variable of the system) or to the desired flow of the slave gas (of the respective slave gases) in such a way that the mixture ratio of the gases involved changes in the direction of the desired mixture ratio. <IMAGE>
