Patent DE-3911297-A1 (DE)
Title: Heating of buildings by continuously recirculating heat and heat pump
Inventor: HURDES VLASTISLAV JOSEF DR ING
IPC: F24D15/04
Filed: 1989-04-07
Abstract: A method for heating buildings by continuous recirculation of some of the heating heat and heat pump, at the same time meeting the hot-water demand. The heat required for the heat-pump evaporator is furnished primarily by recovery of the building waste heat escaping through the outer walls 16 and with the building outgoing air 17. To fully meet the building heat demand, the driving energy 20 of the heat pump 22 replaces those residual losses 21 of the heated building which are not recovered. The building waste heat escaping through the outer walls is recovered in a heat-insulating air gap which is formed between a facade covering and a heat-insulating layer and into which heat recovery pipes are inserted. By using the facade covering as a solar energy absorber, it is possible to utilise solar energy at the same time. There is the possibility of also utilising enviromental heat by means of the installations for recovery of building waste heat. This method is intended primarily for meeting the heat demand of larger building properties by means of monovalent heat-pump installations. <IMAGE>

Title: Cross welding of foil hose bags - by two revolving shafts for pairs of jaw strips running in closed curved tracks
Inventor: KEIM DIETER
IPC: B29C65/74
Filed: 1989-06-16
Abstract: Carrier bags are made of weldable plastic foils by joining the webs by transverse welds, using parallel welding jaw strips (3,4,5,6). Two shafts (1,2) at a fixed centre distance are coupled by drive gear wheels in a frame (7). Each shaft has two end discs, joined by two bearing blocks (18) with two rollers (19) at each end.  Each block carries one welding  jaw strip (3,4,5,6). All rolls (19) run in closed curved tracks (8) with a flat middle section (12).  A control disc on the bottom shaft and a scanning element can be moved by a hydraulic actuator to exert a squeezing pressure on the strip (4,5) and (3,4). ADVANTAGE - This ensures a jaw strip motion in synchronism and their squeeze at a given pressure.

Title: Card can transport tracks -  enable cans to be transported between machines in continuous flow
Inventor: PETER THOMAS
IPC: D01H9/18
Filed: 1990-10-05
Abstract: Sliver cans which are being filled at a drawframe are directed continuously to the roving frames. They follow a track which is equipped with a series of projection to engage in the base of the can. The projections may be raised above track level or lowered beneath it, by means of connecting rods. The track pref. has two sides, open at the top (22). The channel (23) is sunk into the ground so that the top (22) is at floor level. The bottom of the can pref. has a cavity which accepts the projection (25). This may be raised by the connecting rod (33) which is attached to a pneumatic cylinder (34). The rod (33) draws the lever (32) raising lever (31) which lies beneath a sleeve (30), in which slides a coupling to the base of the projection (25). The end of the coupling rests against a stud (26) and may be positioned by the motor (29), gears, and helical drive (27). ADVANTAGE - The projections are small and manoeuvrable, so that the track can be cleared to allow cross travel without creating a hazard.
