Patent DE-2723080-A1 (DE)
Title: Rolled material ejection mechanism from conveyor - has thruster and supporting arms on separate axes on swing arms
Inventor: KREISEL PAUL
IPC: B65G47/82
Filed: 1977-05-21
Abstract: The mechanism ejects and separates lengths of rolled material eg billets delivered in pairs on a roller conveyor onto a further conveyor by means of a thruster linkage. On the side of the incoming conveyor(1) furthest from the outgoing one are swing arms(4) on axes and spaced apart, two or more in number. At the free end of each are thruster(9) and supporting(10) arms on separate axes(9a, 10a) pivoting together, and sliding in the lengthwise direction in relation to each other. These two axes are at different radii from the swing arm axis, that of the thruster arm being uppermost. The thruster arm is coupled to the supporting arm so as to slide in relation to it in the ejection plane. The supporting arm is extended beyond its axis, being coupled at the free end to the piston rod(15a) of a ram(15) also pivoting on an axis(16) and extending roughly parallel to the swing arm.

Title: Bathroom cabinet for physically handicapped - allows bottles, tooth-paste etc. to be stored horizontally using open ended box
Inventor: PHILIPPEN DIETER P
IPC: A47B55/00
Filed: 1977-08-24
Abstract: Bathroom cabinet for the physically handicapped consists of a rectangular open-ended box attached to the wall underneath the mirror. The box is divided into separate compartments so that separate items such as tubes of toothpaste, toothbrushes, bottles etc. can be stored horizontally with their ends projecting clear of the box. This arrangement enables a physically handicapped person to get a better grip on the required article. At the same time the arrangement reduces the risk of articles being knocked into the wash basin and causing damage either to the article or to the basin.

Title: Laser system for anti-aircraft defence - uses cryogenic plant on board aircraft for laser gas regeneration, with pump to increase pressure
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H01S3/00
Filed: 1977-09-07
Abstract: The laser is of injection type. A thermo-nuclear plasma is pumped into a liquid injection laser gas without a diaphragm, pumping ions, electrons, photons and neutrons. The laser system is primarily intended for mounting on board of an aircraft. In such case it can be used also for the drive of the aircraft, as well as its weapon, particularly when fusible substances are used for reactive ignition. For the regeneration purposes the aircraft is fitted with a cryogenic plant which recuperates liquid laser gas from the plasma-laser mixture after the outflow. The pumping system serves simultaneously for storage pressure generation.

Title: Crop dryer using solar heating - uses solar heat collectors to heat water in storage tank for stand by heating
Inventor: DERNEDDE WERNER DR
IPC: F26B3/28
Filed: 1977-09-30
Abstract: The dryer for agricultural or other purposes uses a solar heating system to preheat the drying air. Air enters the solar heat collector (2) one end (4) and passes from the other end (6) into the duct (15) from which air is blown through the material to be dried. Water or other heat exchange medium passes through a coil (5) inside the collector (2) and is circulated through an immersion coil (12) in a hot water storage tank (13). This heat can then be used for other purposes or for drying the same agricultural product at night time or when there is little sunshine. A heat sensing device (7) can be used to control the circulation pump (11).

Title: Fusible interlining mfr. - using an electrical field to charge the fabric for electrostatic adhesive particle application
Inventor: CHAPMAN FRANK
IPC: D06M17/00
Filed: 1977-10-06
Abstract: In the mfr. of a fusible interlining, the carrier material is passed through an electrical field formed between an open vessel for the adhesive to be applied in particles and electrical conductor. The adhesive is drawn from the vessel by the electrostatic charge on the material to form an adhesive application on one side. The treated material is heated for the applied adhesive particles to be bonded and melted into place. The process allows a fusible interlining to be made from a variety of fabric types and a range of different fibres.

Title: Electrostatic gas purification using filter medium - with the filter placed between the ionised gas and one electrode
Inventor: BURGER MANFRED ROLF
IPC: B03C3/38
Filed: 1978-01-24
Abstract: Process, partic. for the purification of air in an enclosed space, uses an appts. which comprises a microporous filtration medium in co-operation with an electrostatic field.

Patent DE-2821892-A1 (DE)
Inventor: PLANKENAUER GERHARD
IPC: B29D30/52
Filed: 1978-05-19
Abstract: The pneumatic tyre with side walls (1) and prepared tread surface (2) is enclosed by an annular chamber (3, 6) in which a new tread strip (4) is fastened with lateral tabs (5). The tabs (5) are clamped between the chamber part (3) and the lateral rings (6). Then, by introducing steam through the inlet opening (7), the tread strip (4) is pressed against the tread surface (2), the contact between the tread strip (4) and the tread surface (2) advancing from the centre outwards. Air inclusions are thereby avoided. The arrangement of the lateral tabs (5) on the tread strip (4) facilitates the insertion of the tread strip (4) into the annular chamber (3, 6). <IMAGE>

Title: Single or two-sideband signal transmission with suppressed carrier - has each data block preceded by test pulse train containing complete pseudo-noise train
Inventor: ESPRESTER RALF DIPL ING
IPC: H04L27/02
Filed: 1978-05-26
Abstract: The method is suitable for linearly distorting circuits with a frequency shift due to Doppler effect. The signals are transmitted in data blocks preceded by a test pulse train. A carrier is added at the receiver directly and shifted by 90 deg. in two orthogonal channels. The pulse response of the transmission circuit is determined and filter parameters corrected accordingly. Deviation of the added carrier from the required value is determined by comparison of amplitudes of two consecutive compressed test pulse trains in both orthogonal channels and compensated as in 26 08 258. Each test pulse train contains at least one complete pseudo noise train.

Title: Inflatable pad protecting skin transplant - has inspection window covering transplant zone and valve for injecting treatment fluid
IPC: A61F13/00
Filed: 1978-09-16
Abstract: The inflatable pad for plastic surgery, used to protect a skin transplant, consists of two layers of latex (1, 2) with their edges (3) joined and welded to form a seam all round. An opening (4) is formed in one layer, and a stiff transparent is welded into the opening so that the area of the transplant can be viewed. This opening can be larger than the transplant area, so that the edges overlap it, onto the region of the untouched skin.

Title: Heat transfer medium in absorption heating system - stops supply of refrigerating medium to absorber below set temp.
Inventor: GRUBER FRANZ
IPC: F25B30/04
Filed: 1978-12-14
Abstract: The system heats a heat-transfer medium using an absorption pump. Above a set temp. level of the heat source a rich solution of refrigerating medium is heated by indirect heat-exchange with a weak solution, the latter being thus cooled before entry into the absorber. Below this temp. level absorption of the medium by the weak solution can no longer take place to an appreciable degree, due to thermodynamic conditions. Below the level concerned, the supply of refrigerating medium to the absorber is stopped, and the weak solution heated in the ejector is fed directly to the absorber. Here it is cooled by indirect heat-exchange with a heat-transfer medium, and then re-heated in the ejector.

IPC: A01M1/14
Filed: 1979-01-15
Abstract: The destruction system is for small house flies and similar insects with the aid of glue. It utilises the habit of such flies to settle on the underside of bodies suspended freely in a room. The fly catching device has a body with a glue-coated flat or curved underside suspended at a point frequented by the flies in the room, and pref. above head height. The size of the body, if necessary with a lamp above it, can be chosen as that at which the flies are most apt to buzz around. The lamp exerts a powerful attracting effect on the flies, which naturally tend to fly toward it.
