Title: Electronic thermostat for compression refrigerator - with delay before switching on again to allow reduction in pressure of refrigerant
Inventor: ZWICKER WOLFGANG DIPL ING
IPC: G05D23/24
Filed: 1974-09-21
Abstract: Electronic thermostat for compression refrigerator or freezer comprises a temp. sensor (NTC9 for the refrigerator chamber, and a switch (TR) e.g. thyristor or triac in the load circuit of the compressor. A trigger signal derived from the cut-off edge of the compressor current or ignition current is used to control a time function member (Z) e.g. monostable multivibrator which blocks the control circuit of the thermostat between the temp. sensor and the switch so that during operation of the time function member variations in temp. in the refrigerator chamber do not allow the compressor to be switched on again.

Title: Electronic switching circuit for model railway - avoids delay due to inertia when reversing direction of motor
Inventor: MOLDASCHL BERT
IPC: A63H19/24
Filed: 1974-11-15
Abstract: The transistor (T1) is non-conducting due to the driving voltage when the motor is running and the Zener diode (4) is also non-conducting. The transistor (T2) is conducting allowing the motor (9) to run. To change the motor direction an excess coltage impulse (usually 24V) overrides the interruption voltage of the Zener diode (4) so that it becomes conducting causing the transistor (T2) to open and through the now conducting collector-emitting of the transistor (T1), the relay (6) is excited and the motor (9) is disconnected. The relay (6) now switches the stator windings of the series wound motor (9) to the opposite rotation without any delay as is the case with mechanical relays.

Title: Electric machine with slip-rungs acting as current reversers - either has rings eccentrically mounted or uses mechanically oscillating brushes (OE150376)
Inventor: OSWALD HANS ING
IPC: H02K13/00
Filed: 1975-11-14
Abstract: The electrical machine has its armature field windings permanently connected to slip-rings and a current direction control triggered by the rotor's angular position. The slip-rings (S1-S4) also act as reversing contacts for the current direction by coming into contact with brushes periodically. This periodic contacting is achieved by mounting the slip-ring assembly eccentrically on the shaft of the machine or by causing the brushes themselves to oscillate. If the oscillating brushes are used then the slip-rings are mounted on the end of the shaft and the brush assembly pivoted backwards and forwards across them.

Title: Impregnation of rovings with resin by injection - for supporting and spacing wires in end winding of electrical machine
Inventor: HENNY JEAN-DANIEL DR
IPC: H02K15/12
Filed: 1975-12-05
Abstract: Method for spacing and supporting the wires and coils in the end winding of an electrical machine is carried out by injecting resin into the rovings, to impregnate them, pref. using a hollow needle. The resin may be a cold-curable highly reactive resin consisting of two or more components, may be mixed in mixing appts. (C) and may have a gelling time of 2-20 mins. The resins used may be epoxy resins, polyurethane resins, or unsaturated polyester resin. The rovings may be provided with a partially air-permeable sheath, pref. a flexible lacquer. By the above method, the rovings can be impregnated from the inside, the air in the rovings is displaced outwardly and air bubble formation is eliminated, providing greater mechanical strength of the end windings. Due to the heat of reaction of the resin, a high degree of curing is obtd. which increases heat resistance of the resin.

Title: Pallet loading of layers of objects - which are slid from support surface on carrying surface and transferred from surface on pallet
Inventor: ROBERTSSON JAN
IPC: B65G57/24
Filed: 1975-12-24
Abstract: The objects are arranged on pallets in layers of a predetermined pattern by which a complete layer of a pattern of objects is grouped on a support which offers very little resistance against moving the object along its surface. Thereafter the grouped objects are transferred in the same pattern on a comparatively thin carrier by which they are transported to the pallet. With the carrier positioned in required relative position to the pallet the layer of objects are transferred on the pallet. The grouped pattern of objects are transferred from the support on the carrier by positioning the carrier level with the top surface of the support and by removing sidewards the support below the objects and replacing it by the similarly moving carrier.

Title: Car heater with recirculating facility - has fresh air inlet shut and colder air drawn from foot level
Inventor: VOIGT HARTMUT VON
IPC: B60H1/00
Filed: 1976-04-06
Abstract: In normal use the car heater draws in fresh air through an inlet duct (7) and passes it over a heat exchanger (6) to blow through windscreen (5) and foot level (10) ducts. If the outside air becomes too polluted, in dense traffic, then special flaps (14, 12) can be operated to shut off the inlet duct (flap 8) and separate the foot level and face level ducts (flap 12). A blower (15) then recirculates the air. Air is drawn in through the foot level duct and passed over the heat exchanger before being expelled through the face level duct. The system prevents the car from becoming too cold, and the windows from misting, when the fresh air inlet is closed.
