Title: Filter unit
Inventor: SCHMIDT HANS-WEDDO
IPC: B01D63/00
Filed: 1981-10-17
Abstract: A filter unit of small overall size for the sterile filtration of liquids in the medical, laboratory and dental fields can either be inserted into a housing-like surrounding component or is enclosed by a tubular plastic housing (10, 11, 12), and it consists of a plurality of bag-shaped filter elements (1, 1') layered at a mutual spacing and consisting of a microporous membrane filter material and/or of a microporous filter fabric and/or filter nonwoven, whose bag openings (2) are superposed. A synthetic resin disc (5) fixes the filter elements (1, 1') in the region of their bag openings (9), the solidified synthetic resin surrounding the outer periphery of the bag-shaped filter elements (1, 1') making a seal, but leaving the bag openings (9) free. For use, for example, in a dental instrument, the synthetic resin disc (5) itself forms with its outer circumference or with the disc surfaces (13) left free by the filter elements (1, 1') a seal or a sealable flat surface. A filter constructed as a disposable unit consists of an enclosing tubular housing (10, 11, 12) and two mounting discs (7, 8) arranged in the region of the bag openings (9) and having slots (9), open on one side, for fixing the filter elements (1, 1'), one free space between the two mounting discs (7, 8) being filled by spraying with synthetic resin (5') and the filter unit thus being integrated between the connection branches (11 and 12) in the housing (10) in a leak-tight manner. <IMAGE>

Title: Method and device for mechanically placing hooded lids on flanged bases filled with product
IPC: B65B7/28
Filed: 1981-10-30
Abstract: The invention relates to a method and device for mechanically filling and packaging product (4), in particular fruit, in two-part box-like containers (1) of non-rigid material. In such non-stable containers (1), fruit placed therein would result in the bulging of the side walls (6) of the lower parts (2) of the container. In order nevertheless to facilitate mechanical connection of the upper and lower parts (2, 3), the invention proposes that the side walls (6) of the lower container part (2), located in a centring position (25), be bent inwards by means of sliding members (10) so that the side walls (13) of the upper container part (3) can effortlessly be pushed over the lower container part (2), the overlap travel however being less than the travel necessary for the complete closure of the two container parts (2, 3). The sliding members (10) are designed to move aside resiliently on one side. <IMAGE>

Title: Thermodynamic process of "reversed heat pump" and its application to pneumatics
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: F01K25/10
Filed: 1981-12-19
Abstract: The thermodynamic process of "reversed heat pump" realises in pneumatic tools the idea of obtaining an inexpensive operation by using a liquid gas with a very low critical point, e.g. liquid air, which is contained in cartridges and placed in a quickly replaceable fashion mostly in the tool housing, and of doing so under isochoric heating in the presence of environmental heat, occurring freely of high working pressures up to approximately 2000 bar and despite the relatively high cost of liquid air. Above ground, this is of use in tools whenever, given that the latter are of low weight and small size, work is to be carried out for a relatively long time without a compressor and hose, e.g. with 1 litre of medium on board. In the case of deep drilling, there is scarcely any other further alternative to this new stratagem with liquid air since at depths beyond approximately 2000 metres the motor reaction torque and the angular momentum of the string mean that it is an illusion to resupply electric energy by cable, and the loss of pressure means that it is an illusion to resupply compressed air energy by hose. As deep drills, liquid air tools perform to depths of 50,000 metres; thus in a suburb 1500 DEG C geothermal power for heating and electric current in all latitudes, including the Arctic.

Title: Welding device for welding studs or the like to a workpiece
Inventor: RESCH KLAUS
IPC: B23K9/20
Filed: 1982-01-22
Abstract: The welding device for welding studs (8) or the like, having at least one ignition tip (9), to a workpiece (10) has a piston (3) which is displaceably mounted in relation to the housing (1) of the device, carries a stud holder (5) and lies in the discharge circuit of a welding capacitor (34); an actuating mechanism which initiates the welding operation and to which a striking pin (16) under the action of a spring (18) is allocated for acting on the piston (3) in the axial direction during the welding operation; and also a control circuit preventing a welding operation from being triggered before the device is put onto the workpiece. In order to avoid in particular endangering the operator, the striking pin (16), constructed separately from the piston (3) and mounted in such a way as to be displaceable coaxially relative to the piston (3) and in an isolated manner, is acted upon in the direction away from the piston (3) by the spring (18) allocated to it, is arranged in the control circuit run via the piston (3) together with stud (8) and the workpiece (10), and can be acted upon in the direction towards the piston (3) by a solenoid (20) which can be switched on via the actuating mechanism. <IMAGE>

Title: Wheelchair for the sick or invalids
Inventor: HEFTI RUDOLF
IPC: A61G5/04
Filed: 1982-03-15
Abstract: The wheelchair has a blocking device which locks the guide wheels (1) in a position parallel to the longitudinal central plane of the wheelchair. A tension lever (10) is turned by the user, a second tension lever (15) also being turned via a toggle joint (13, 14). This has a relieving effect on tensile springs (22). Each tensile spring is connected to a rod (23) which is partially located inside a cylinder (24) and is displaced on release of the tensile spring (22) by a compression spring (28) located in the cylinder (24) in such a way that a journal guided in the cylinder engages in a bore. This bore is provided in the corresponding fork shaft (4) which forms the vertical axis of the associated guide wheel (1) and is guided in a guide (3). By turning the tension lever (10) in the other direction the two journals are pulled out again, the tensile springs (22) and the compression springs are retensioned and the fork shafts (4) are unblocked. This blocking prevents the guide wheels (1) from standing transversely to the wheelchair, and hence prevents its further movement, on driving over steps, e.g. footways. <IMAGE>

Title: Device for determining the quantity of heat dissipated by heaters or underfloor heating systems, for the purpose of allocating heating costs and simultaneously regulating the heater output
Inventor: RUMP HANNS
IPC: G05D23/19
Filed: 1982-04-15
Abstract: The invention relates to a device for determining the quantity of heat dissipated by heaters or underfloor heating systems, for the purpose of allocating heating costs and simultaneously regulating the heater output. A measuring instrument determines the temperature difference from the mean heater temperature and from the temperature of the incident air, or the feed temperature, return temperature and air temperature are measured and the difference is formed therefrom. In this case, the measuring instrument is matched to the capacity of the heater, in order to obtain directly comparable results. This is performed by entering the heater rated output into the measuring instrument, which is done directly in "Watts" or indirectly via a code. The measuring instrument has an internal regulating system which compares the preselected room temperature with the measured temperature and derives from the difference a value of manipulated variable which adjusts an actuator, generally a conventional thermostat valve. This value of manipulated variable can be proportional to time or can consist of actuating pulses as in a servomotor.

Patent DE-3222398-A1 (DE)
Title: Instant picture film and camera
Inventor: BLECKER GEB MEYER
IPC: G03C8/34
Filed: 1982-06-15
Abstract: An instant picture film, in particular in the form of a sandwich, provides particularly sharp and thus valuable pictures, due to the fact that the neutralisation of the developer can be set manually, it being the case that either additional neutralisation material is released after the removal of the sandwiches from the camera, or is released at any instant which can be independently selected. As a result, the developing process can be stopped precisely at the instant which is most expedient depending on the particular circumstances. Particularly suitable for releasing or influencing the neutralisation materials is a camera in which additional devices are provided below the film cassette in the housing. Here, the particular sandwich can be inserted through a slot into the housing insert, the insertion or also the renewed extraction releasing reservoirs or a separate layer with neutralisation material. <IMAGE>

Title: Transvenous implantable pacemaker electrode
Inventor: SAUBERT GERD
IPC: A61N1/05
Filed: 1982-11-09
Abstract: On installation of pacemaker electrodes they are laid around the pacemaker in the shape of a loop in order to achieve tensile relief. At the transition from the part having relatively low flexibility surrounding the connection plug to the much more flexible jacket of the coil a bend frequently forms, and this represents a higher stress on the coil. In order to avoid this bend the electrode is designed, according to the invention, so that the part surrounding the connection plug is already pre-bent during production or that the Shore hardness of the part surrounding the connection plug decreases, continuously or stepwise, from a relatively high value at the plug end to a lower value at the other end.
