Patent DE-2733744-A1 (DE)
Title: Fixed or movable seat or bed backrest with adjustable curvature - has movable horizontal spacer between base plate and resilient support (SW 14.11.77)
Inventor: WIENER HANS
IPC: A47C7/40
Filed: 1977-07-27
Abstract: Back rest is formed by a rigid rectangular case plate (10) with two longitudinal edges connected by two transverse edges by a curved resilient support (20) which is connected to the base plate at the two transverse edges so that it can be displaced at at least one edge. A spacer (13) designed as a full-length support is mounted in the space between the base plate (10) and the support member (20) where it is pressed against the base plate owing to the elasticity of the support member and lies with its ends near the longitudinal edges of the plate. The length of the spacer is equal to the width of the base plate and its position can be adjusted so that the desired curvature of the support member can be set relative to the base plate. The base plate is provided along at least the middle parts of the longitudinal edges with locking elements (16).

Title: Electrostatic field distribution system using overhead light fittings - uses fluorescent tube housing as electrode which is insulated from second electrode
Inventor: FURCHNER HELMUT
IPC: F24F3/16
Filed: 1977-08-03
Abstract: The system for establishing an electrostatic field in a room uses commercial fluorescent lamp housings (3) to carry the electrodes. The fluorescent lamp tubes (4) are supported inside ceiling mounted housings, and the casing itself forms an electrode. The field lines (9) are then directed vertically downwards. A metal grid (5) forms the other electrode, and is insulated from the remainder of the casing (3) by an insulating layer (6). The grid is then connected by a cable (7) to a suitable generator. Alternative designs include different suspension and insulation arrangements.

Patent DE-2741657-A1 (DE)
Title: Safety circuit for two point temp. controller - has solid state circuit that prevents heating circuit activation if temp. sensor is not connected
Inventor: GERSTEL EBERHARD
IPC: G05D23/275
Filed: 1977-09-16
Abstract: A two-point regulator for the control of temperature in a chemical process plant uses a mercury contact thermometer coupled into a solid state circuit. The circuit is designed to provide protection against a break in the wires connecting to the thermometer. The control circuit has the 220V mains coupled to a rectifier(12, 14), with a reed relay(16) controlled by transistor(18, 42) switching stages. When the reed relay contact(52) is closed the heating circuit is activated. The mercury thermometer is coupled to a socket(28) and depending upon the temperature either causes the heating to be switched on or off. The significant aspect of the solid state circuit is that if the thermometer is not connected to the socket, the main transistor(18) is blocked and the heating switched off.
Patent DE-2743145-A1 (DE)
Title: District heating using power station waste heat - uses ammonia vapour as long distance transport medium with local water heaters
Inventor: BIERSACK RICHARD DIPL ING
IPC: F01K23/04
Filed: 1977-09-24
Abstract: A steam turbine drives a generator. The exhaust steam is condensed in a heat exchanger in which it evaporates ammonia. The ammonia is pumped through a long distance pipe network to local user stations. At local stations the ammonia is compressed and then passed through heat exchangers in which it is condensed. It gives up heat to water which is pumped through a space heating system. The ammonia can also be passed directly through heat exchangers without being compressed to heat water to a lower temperature for domestic use. The use of ammonia for transporting heat reduces insulation requirements.

Title: Operating circuit for doors, protective grids, machines etc. - has magnetic switch operating reed relay when acted upon by external magnet or iron piece changing magnetic field
Inventor: HETZER FRITZ
IPC: H01H36/00
Filed: 1978-06-06
Abstract: A circuit for closing and/or control of doors, protective grids, machines etc, combines a reed relay and a load element such as a relay, triac or trasistors. The switch and the load element are supplied with the same potential. Reversal of the load element switching function ensures mutual control of both switching positions. On a machine safety application the magnetic switch has an inbuilt magnetic system co-operating with an external operating magnet. In a door control system the switch contains the complete magnetic system and the operating element consists of an iron piece changing the magnetic field.
Patent DE-2827227-A1 (DE)
Title: Polyethylene ampoule for medicaments - having cap for neck with rounded edges for smooth insertion
Inventor: BRACHT JUERGEN
IPC: A61J1/06
Filed: 1978-06-21
Abstract: An ampulla, made of polyethylene, for medicaments is joined by thin tear-off straps to others to form a continuous row. The closing caps fit over the ampulla necks with an inner plug and an outer collar. The edges of the necks are well rounded.

Inventor: WANNER HANS
IPC: B28D1/04
Filed: 1978-08-04
Abstract: The apparatus consists of a drilling arrangement (39) and a positioning device (38). The drilling arrangement (39) has a drilling machine (1), a feed device (4) and an adjusting device (8) for adjusting the drilling angle.

Patent DE-2850019-A1 (DE)
Title: Condensable components separation from gas - using vortex chamber keeping raw and hot gas pressure to specimen ratio
Inventor: MIKA GYOERGY DIPL CHEM ING
IPC: F25J3/06
Filed: 1978-11-17
Abstract: Condensable products such as water liq. hydrocarbon are separated from natural gas by expanding the mixt. in a vortex chamber. Aided by the centrifugal force and the Ranque-Hilsch vortex effect, a cold and a hot gas stream are extracted, keeping the pressure ratio between gas intake and hot gas stream is 1.7 to 7. The cold gas stream is used to cool the mixt. before it enters. The liq. is extracted from the vortex chamber when its temperature and composition differs from that of the gas outflow. This creates a simple way of separating water and liq. hydrocarbon from natural gas and of minimising the erosion effect on the separator.

Title: Cover for converting open domestic bath to enclosed (steam) bath - incorporating polyethylene mouldings, and waterproof nylon aprons
Inventor: GEISLER NEVILLE
IPC: A47K3/00
Filed: 1978-12-11
Abstract: A hollow casing with flexible waterproof aprons, extendable from internal storage rollers is described for enclosing a domestic bath to simulate a steam bath. The casing is assembled from complementary mouldings of e.g. polyethylene and the aprons from woven polyamide ('nylon') fabric reinforced at intervals by transverse rods of metal or rigid plastic slats. The casings may be secured by spring loaded legs fitted with suction cups. Opt. internal strips of elastic foam sweep excess water from the apron(s) during recoil. One apron features a cut segment or slit to allow a bathers head or shoulders to project above the level of the cover. The design is suitable for conventional bathroom layouts and provides relatively easy access/egrees, avoids use of sliding clasp fastenings.
Patent DE-2856501-A1 (DE)
Title: Large cyclone self cleaning liner - has flexible inner member with cavities behind connected alternately to atmosphere and to gas supply to create pulsing action
Inventor: STRAUSS WERNER
IPC: B01D45/12
Filed: 1978-12-28
Abstract: Cyclone separator removes solids from an air stream. It has a flexible inner lining behind which sealed cavities or chambers are located. These are interconnected via an external pipe. The pipe is connected to a valve system which which allows the line to be connected up either to the body of the cyclone or to the external atmosphere. By constantly alternating the pressure in this way, the flexible wall is caused to move to and fro. This movement induces any solids collecting on its surface to slide down its conical profile, into the base. Used for removing damp, coherent materials from gas streams. Build up of these materials is avoided.
