Patent DE-4322247-A1 (DE)
Title: Domestic circulating-air upright freezer with insertable insulating partition plate
Inventor: SCHOTTE GERD
IPC: F25D23/06
Filed: 1993-07-03
Abstract: The insulating partition plate required for division of the freezing compartment, and drawers which may thus possibly become superfluous, are to be stowed in a space-saving and ordered fashion and be accessible quickly and conveniently to the user, if needed. In the case of known appliances, there is no provision for this. In the case of the domestic circulating-air upright freezer according to the invention, the partition plate (6) mentioned is employed instead of a freezing tray (4) arranged at half height of the appliance. The freezing tray (4), thus not required, is accommodated in a positionally secure manner within a deepened recess of the appliance door (7). When the freezing compartment is fully utilised and the freezing tray (4) inserted, the partition plate (6), which is now no longer required, is likewise stowed fixedly in the aforementioned door recess. Insulating partition plates serve to divide the freezing compartment when the circulating-air upright freezers are not fully occupied, and produce very substantial energy savings. <IMAGE>

Title: Refrigerating unit, esp. for air-conditioning in railway train - has spring-loaded, inclined-seat safety valve between evaporator and compressor, controlled by pressure on exit side of compressor
Inventor: KONRAD WALTER
IPC: F25B41/04
Filed: 1993-07-09
Abstract: The refrigerating unit has a circuit with compressor, condenser, expansion valve and evaporator. Between evaporator and compressor, there is a pressure-controlled spring-loaded safety valve. This valve is an inclined-seat poppet valve with a head connected to the piston by a rod with internal axial passage. The passage is open to the spring side of the piston and to the suction side of the compressor. The reverse side of the piston is connected by a control pipe to the pressure side of the compressor. The sealing of the suction side entry port to the compressor is complete when the valve is closed. ADVANTAGE - Simple inexpensive protective device for compressor.

Title: Process for filling wall, ceiling or floor cavities in buildings with filling material
Inventor: KITZINGER FRANZ
IPC: E04B1/76
Filed: 1993-07-13
Abstract: A process for filling wall, ceiling or floor cavities in buildings, in particular those with frameworks, with, in particular, heat-insulating and/or vibration-damping filling material is intended to be possible to be carried out in a more cost-effective manner than has been conventional hitherto. In particular, the intention is to use, for the filling material, recycling material which can be brought in granular form to the location of the cavities which are to be filled. For this purpose, the filling material consists of essentially comminuted old rubber tyre material which is mixed with a two-component adhesive and is introduced into the cavity in the as yet non-hardened free-flowing or pourable state. The introduction of the free-flowing or pourable filling material expediently takes place under pressure. The cavity which is to be filled can be lined with sheeting in order that the material which is introduced does not bond fixedly to the inner walls of the cavity.

Title: Magnetic gripper
Inventor: KIENEMUND ALBRECHT PAUL DIPL P
IPC: B65G47/92
Filed: 1993-08-21
Abstract: The invention relates to a magnetic gripper for manual and automatic handling of objects, in particular of toroidal tape cores. The various designs of known magnetic grippers have a series of disadvantages, for example with respect to the individualisation of the objects, the geometrical delimitation of the magnetic force effect, the control with time of the magnetic effect and the like. Permanent magnets (15, 16) are therefore arranged between two soft iron pole shoes (10, 11), which are separated by an air gap (12), in such a manner that by moving at least one of the permanent magnets (16) a magnetic field compensation or the excitation of a magnetic field in the pole shoes (10, 11) can be switched alternately. <IMAGE>
