Patent FR-2481362-A1 (FR)
Inventor: FORSTER HANS
IPC: F25B15/02
Filed: 1981-01-28
Abstract: The invention relates to a method of generating mechanical energy from waste heat as a downstream process in thermodynamic methods and cyclic processes which produce waste heat, the usable heat conversion being in the low temperature region (</= 250 DEG C). The object of the invention is to design a thermodynamic circulation process in such a way that low level waste heat can be used to produce energy by cooling to appreciably below 100 DEG C. The essence of the invention is to be seen in the fact that, in a cyclic process, a high-pressure working substance is released by desorption at high pressure, superheated, let down in a multistage bleeding turbine to produce work and dissolved again in the liquid solution, i.e. in the absorbent, by stepwise absorption. Fields of application of the invention are in all waste-heat producing processes, such as: - nuclear power plants embodying a high-temperature helium turbine process, - chemical plants, - drying processes, - processes which produce flue gas.

Patent FR-2477805-A1 (FR)
Inventor: BOCKELMANN PAUL
IPC: G08G1/09
Filed: 1981-03-04
Abstract: To generate a switching signal with the occurrence of a periodic electrical signal lasting at least some periods in a traffic broadcast receiver, the signal is supplied to an input of a first threshold switch (12). This controls a current source arrangement (14, 15, 16) in dependence on the instantaneous value of the input signal, in such a manner that a capacitor (13) is either charged or discharged. The charging and discharging currents deviate from one another. The voltage across the capacitor (13) is used for controlling a second threshold switch (17) which generates the switching signal at a predetermined capacitor voltage. Thus, only one capacitor (13) instead of the usual two capacitors is needed for generating the switching state.

Patent FR-2478224-A1 (FR)
Inventor: LEWIS GEOFFREY ARTHUR
IPC: F04D29/44
Filed: 1981-03-11
Abstract: A centrifugal pump has a first bladed impeller (14) and a second rotor (15) which surrounds the first rotor (14) and whose inner circumference closely adjoins the outer circumference of the rotor (14). The second rotor (15) has a multiplicity of orifices (34) through which essentially the entire volume of the liquid between the pump inlet (12) and a tangential outlet is forced. The second rotor (15) can be rotated at half the rotational speed of the first rotor (14), as a result of which the losses due to the flow resistance between the rotor (14) and the pump casing (10) are reduced. On the other hand, the rotor (15) can be driven by the liquid flowing through, and at least part of the energy normally lost to the flow resistance can be recovered at a shaft (22).

Title: Upholstery panel for sprung automobile seat - of polyurethane foam bonded to polyester nonwoven has high tearing strength and low weight
Inventor: HULBERT FRANZ-ANTON
IPC: B60N2/70
Filed: 1981-03-23
Abstract: An upholstery composite for spring seats of automobiles consists of polyurethane foam and a non-woven based upon polyester fibres bonded to this foam. Preferably, the foam is 10-30 (15-25) mm thick and the non-woven 0.2-3 (0.5-2.5) mm. thick. In a preferred embodiment the foam projects at opposite or all four sides beyond the non-woven and a portion of the non-woven remains unbonded to the foam at the edges so that it can be folded back and fitted around the metal frame. The non-woven pref. contains venting holes at intervals, more specifically for the stitching in of short pipes. As a replacement for the heavier, previously used material for the upholstering of automobile seats containing steel springs. The new material is lighter than the normally used fibrous material, rubber material or latex-bonded coconut fibrous material combined with polyurethane foam and textile covering. It nevertheless possesses the necessary tearing strength and comfort.

Title: Soldering of silver parts onto copper parts - using silver:cadmium preform with silver phosphide preform to make strong joint and to reduce amt. of silver required
Inventor: KETT GERHARD
IPC: H01H1/023
Filed: 1981-03-26
Abstract: A part contg. Ag is to be soldered to a second part made of Cu or its alloys or of Cu plus steel. Both parts are cleaned, and then a solder layer consisting of AgP and AgCd is placed between the parts, followed by heating to make a soldered joint. The layer of of AgP and AgCd may be made by melting to make a sheet or rod; or two sheets may be made, one of AgP, the other of AgCd, and rolled together to make a clad or bimetal strip. The process is used esp. to solder a contact made of a silver alloy, esp. AgCdO, AgC, AgZnO, or AgSnO, onto a contact carrier made of Cu or a steel contg. Cu. A frequently used contact material is AgC, viz. 95% Ag with 5% graphite, which is very resistant to welding of contact surfaces, but this material also needs a lot of Ag for conventional soldering. Contacts are normally soldered onto their carriers by a layer of silver, which is very expensive. The invention uses a less costly solder, viz. a preform of AgCd and AgP.
