Title: Anaesthetising chamber for animals to be slaughtered - reduces gas consumption by cooling gas to below ambient temp.
Inventor: KILDEGAARD EJVIND
IPC: A22B3/00
Filed: 1980-09-30
Abstract: Abutting plant installation is for anaesthetising animals, partic. pigs, just before they are slaughered. The installation is of the type in which the animals are suspended in carriers of an elevator which advances them through a vertical shaft contg. an anaesthetic gas, pref. CO2. Each anaesthetised animal is delivered alongside the alongside the elevator loading point. The anaesthetic gas inside the shaft is kept at a temp. below ambient. The temp. of the gas is pref. not low enough to produce condensn. inside the shaft. The shaft temp. is pref. maintained by a thermostatically controlled, cooling jacket. A substantial proportion of the vol. of the shaft is pref. filled with an inflatable bag. Gas is pref. injected into the shaft through a number of inlets spaced around the top of the shaft. The consumption of CO2 per animal is substantially reduced by cooling the gas to counteract the heating effect of introducing warm animals into the shaft. There is a gas saving of some 20% on the previous consumption figure of about 140g per pig an aesthetised.

Patent FR-2496362-A1 (FR)
Title: Isolated input power switching transistor control circuit - has opto-isolator or pulse transformer input pulse to initiate transistor turn on with self sustaining action and blocking
Inventor: GUILLON JEAN-CLAUDE
IPC: H03K17/64
Filed: 1980-12-12
Abstract: Control impulses or variable delays are generated in a part tied to a cold earth. Only the input, driver and switching circuit are powered directly by a rectifier connected to the supply. Four foward biased diodes in series connected to the power transistor emitter provide passive security by blocking the transistor in the absence of a control signal. Control signal input isolation is provided by a pulse transformer or opto-isolator. The phototransistor or pulse transformer output transistor has an anti-saturation diode connected to its collector which is connected to the base of the first of the driver transistor pair. A secondary winding of the power transformer is connected by diodes and a limiting resistor to the power transistor to provide self-drive in the saturated state. Turing the control transistor on blocks the driver transistors switching on the power output transistor. The emitter diodes are bridged by a long time constant capacitor reservoir. The two diodes in series providing regenerative feedback are connected by resistor to the supply to lower the level necessary to start saturation using the feedback winding and by an anti-saturation diode to the collector of the output transistor. This limits the base voltage to within five times the forward biasses diode voltage drop.

Title: Continuous centrifugal separator - employs combined cylindrical-double conical bowl with reversible scroll
Inventor: BESSON PAUL
IPC: B04B1/20
Filed: 1981-07-02
Abstract: Continuous centrifuge employs a bowl having cylindrical as well as conical sections. The conical section is fitted with a replaceable section at the discharge end to give a double-conical configuration. A scroll, driven at low speed in either direction with respect to the bowl is used to effect discharge of the heavy phase from either end of the machine. A sleeved scroll section at the conical end suits the increased angle of the double-conical section. A disc at the end of the scroll enables the heavy phase to be discharged through what would conventionally be the light phase discharge ports. The length of the cylindrical section and the double-conical design enables the machine to operate with very low density differentials e.g. for concentration or separation of biological sludges.
