Title: Heating system using heat pump - includes evaporator and thermostat in cool room and second evaporator in boiler room
Inventor: LIEBE FRIEDRICH ING GRAD
IPC: F24D11/02
Filed: 1978-11-29
Abstract: The heating system using the heat pump principle, uses one room of a house kept at a lower temperature than the room in which the heating unit and hot water tank are installed. The cooler room houses an evaporator for the heat pump, and the second room houses a second evaporator. Both evaporators are connected to the compressor of the heat pump. The compressor is in the second room, and a thermostat in the cooler room connects the second evaporator to the compressor when the first compressor is disconnected. This happens when the cooler room reaches its required temperature limit. This temperature is suitable for using the room as a cool room in summer particularly for food storage.

Title: Needle-punched pile fabric with high pile-density - produced by incorporating plastic film in web before punching
Inventor: LOCHNER HERBERT DR
IPC: D04H1/08
Filed: 1980-02-23
Abstract: A pile fabric consisting of at least one solid or multi-coloured needle-punched web incorporates a film of polyethylene or polypropylene 70-300 microns in thickness, pref. 100-150 microns, through which the fibres of the web are punched to produce the pile surface. The plastic film may be sandwiched between the two webs, whereby fibres of one web are punched through the film to mingle with the fibres of the other in forming a mixed pile. At least one of the webs may also be treated with a bonding agent, to produce a figured pile on punching. The plastic film improves the dimensional stability of the fabric. It also has a check-valve action on the needled fibres, preventing them being drawn back into the web when the needles reverse their motion, giving a considerable increase in the pile density compared to conventional needle-punched fabric, and approaching that of tufted material.

Patent DE-3008937-A1 (DE)
Title: Salient pole stator and slotted rotor machine - has interpolar and slot opening filling strips to give cylindrical surfaces to reduce windage noise
Inventor: ALTMANN MANFRED DIPL ING
IPC: H02K3/487
Filed: 1980-03-08
Abstract: The motor is for domestic equipment, e.g. washing machines. Where salient pole machines are used, typically commutator motors, the interaction between the space between stator poles and the armature slot openings can give rise to considerable windage noise where the fundamental frequency is proportional to speed. To assist in suppressing the component of noise it is desirable to have smooth, cylindrical surfaces on stator and rotor. In order to achieve the required surface, the space between pole shoes is closed by fitting non-metallic plates between the pole tips. The plates are profiled to continue the contour of the pole face. Similarly the armature slots are closed with wedges whose profile is such that they extend to the armature periphery. The wedges preferably leave a minimum gap between the sides and the tooth tips.
