Patent FR-2469679-A1 (FR)
IPC: F25B30/02
Filed: 1980-10-29
Abstract: The air-conditioning device can be used as a heat pump and has a compressor (10), a condenser (11), an expansion valve (12) and an evaporator (13). Arranged between condenser (11) and expansion valve (12) in the refrigeration circuit is a heat exchanger (18). Located between the compressor (10) and the condenser (11) is a heating heat exchanger (19). The evaporator (13) is also assigned an additional heat exchanger (27), through which cooling liquid flows from the cylinder head (29) of the compressor (10) and the encapsulated drive motor (15). Fitted in the evaporator (13) is a further heat exchanger (21) which is flowed through by a heating medium which extracts heat in the heating heat exchanger (19) as required. The heat exchanger (18), the additional heat exchanger (27) and the further heat exchanger (21) are all situated in the air flow of the evaporator (13). By means of the heat exchanger (18), which delivers heat from refrigerant conducted in it to the air, the evaporation temperature of the refrigerant is lowered. In the evaporator (13), the refrigerant can extract a lot of heat energy from the outside air even at low temperatures. The additional heat exchanger (19) makes it possible to de-ice the evaporator (13) or keep it free of ice constantly.

Patent FR-2505547-A1 (FR)
Inventor: MENTZER REGIS
IPC: B65D73/02
Filed: 1981-05-08
Abstract: The invention relates to a supporting strip for connections for capacitors or the like, a strip provided with such connections and a process for fixing capacitors to such connections. According to the invention, the connection supporting strip has series of upper and lower slots, which are respectively aligned with one another. Each upper slot is wider than the corresponding lower slot in such a way that the introduction of hairpin-like connections with a base shaped like a U located on the side of the upper slot brings about a progressive tightening of the ends of the arms of said connections. This leads to an improvement of the fixing of clips or tabs for capacitors of the "paving stone" type prior to the welding and coating stages. Application to the production of capacitors.

Title: Digital surface controller for ground probing tests - contains microprocessor performing calculations and issuing commands resulting from pressure and water level sensor inputs
Inventor: LEBLANC JEAN
IPC: E02D1/02
Filed: 1981-06-12
Abstract: A microprocessor is connected by an I/O bus to program memories and to a dynamic memory protected by a special battery connected to a charger. A dynamic working memory is used for the calculations required during the control operations. The bus is also connected to an auxiliary calculator and to a converter converting measurements from the semiconductor pressure sensors to digital formed for the microprocessor.

Title: Personal holder for self administered injection syringe - for holding and discharging multiple interchangeable disposable syringes
Inventor: GALY MICHEL
IPC: A61M5/19
Filed: 1981-07-15
Abstract: Self-injection tool for subcutaneous introduction of 1 or more medicant solns. comprises a tubular casing for housing 1 or more loaded syringes each with its own piston and needle by which the contents can be discharged under pressure applied by a spring loaded cap sliding within the casing. Prior to use, an ancillary cover encloses the end(s) of the syringe needle(s) and a coaxial rod maintains ball catches in positions which lock the sliding cap. For use, the protecting cover is removed and the casing is applied to the skin with sufficient pressure to shift the coaxial rod until the internal sliding cap is disengaged. The cap moves to extend the syringes and then discharge them. Used esp. for individual packs for accepting disposable syringes to administer interactive medicants simultaneously but separately, e.g. to counteract exposure to nerve gas or allergy systems. 3 alternative spring catch details are described. Provides a combination of low cost, portability and long term sterile enclosure for accepting replaceable or alternative syringes.

Title: Control of deep drilling, esp. in winning petroleum, or gas - where computer contg. drilling model is used to feed optimum control signals to drilling plant
IPC: E21B44/00
Filed: 1981-12-22
Abstract: The process and plant include a drill, which is driven in a known manner by a motor and winch receiving control signals from a digital/analogue (D/A) converter. The converter receives signals from a computer, which contains a drilling model and which receives signals from three sensors monitoring the drilling speed, the load on the drill, and the r.p.m. of the drill. The signals from the sensors are compared with optimum values derived from the drilling model so the control signals delivered by the D/A converter to the motor and winch can be adjusted to match the type of underground rocks etc. through which the drill travels, e.g. so excessive wear of the drill cutters can be avoided.
