Title: Double glazing by welding glass panes along their edges - using air-cushion to support and cool weld
Inventor: KIENLE RAINER DR
IPC: C03B23/24
Filed: 1974-11-14
Abstract: Device for mfg. double glazing by welding the upper horizontal edges of two vertical glass panes sepd. by a gap, where the edges are heated by burners and bent by forming rolls so the edges meet, the forming rolls being followed by polishing burners. The novelty is that downstream of the forming rolls and between the panes, directly under the welded zone, is a supporting device consisting of a nozzle, and a cold gas such as air streams out of the nozzle. The shape of the nozzle pref. matches the internal contour of the welded edges, and the nozzles are pref. detachably located in their carrying pipe so interchangeable nozzles can be used. The nozzle provides a gas-cushion which mechanically supports the hot glass and also provides cooling, the combined effects preventing distortion of the hot welded edge.

Title: New car degreasing installation - has grease and kerosene recovered from waste water for use as fuel for reheating water
Inventor: FREY EUGEN
IPC: B60S3/04
Filed: 1974-12-18
Abstract: The installation is used for removing protective grease from new cars. The cars are sprayed with hot water with a considerable amount of kerosene added from a manifold (4) with sets of nozzles (8). The waste water containing the kerosene and the removed wax is collected via a floor grille (5) in a pan (6) and then conveyed to a settling tank (10). The kerosene and wax stay at the top of the water level, from where they are removed by a pump (25) via a floating strainer and discharged to the tank (12) connected to the boiler (13). The heated-up emulsion is then treated in a centrifuge (30) which separates the water for re-using in the rinsing operation. The separated kerosene and wax is piped to a further settling tank.

Title: Power stage for supply networks - has parallel power transistors cross coupled base to collector over two transformers
Inventor: LUETTICH ROLF DIPL ING
IPC: H02M7/5381
Filed: 1974-12-18
Abstract: The power stage for supply networks has parallel-coupled power transistors and two transformers (T1, T2) that generate a base current proportional to the collecting current. The two power transistors (V1, V2) are so arranged that the base current of one transistor (V2) is supplied from the transformer that lies in the collector circuit of the second transistor, and the base current of the second transistor is supplied by the transformer lying in the first transistor collector circuit. Diodes (V5, V6) are located between the transformers and the transistor bases. The advantage lies in the use of cheap components.

Title: Device for jointing box-shaped metal bars - cutting and pressure tool to press bars onto anvils
Inventor: FEDERHENN HARTMUT
IPC: B21D53/74
Filed: 1975-04-11

Title: Fibrous filter wrappings, esp. coconut fibre, on drainage pipes - by reconstituting and binding opened rope
Inventor: ROESS HANS
IPC: F16L55/00
Filed: 1975-07-31
Abstract: Strands of fibrous matl., secured to the pipes by winding round with a thread or a tape, are produced from a predetermined quantity of fibre in the form of solid twisted strands on rope reels, corresponding to the desired final dimensions of the wrapping strand. The primary strands are drawn from the reels and disintegrated in a fibre opener, to be converted by a fan feeding through a pressure line into a stuffing tube into a loosely densified secondary strand. This in turn is fed spirally to form a tertiary strand of high matl. density which is compressed and fixed in its final form on the pipe. Feeds the fibre uniformly and without dust, so that an effective filter devoid of holes, is ensured over the full length of the pipe.

Title: Pneumatic valve for trailer brakes - has failsafe interlock to apply brakes when line to trailer is cut
Inventor: GRAUEL INGOLF DIPL ING
IPC: B60T13/38
Filed: 1976-04-10
Abstract: The dual circuit pneumatic brakes for the lorry and trailer have a brake control valve in the coupling to the trailer brakes. A flow restriction monitors the air flow to the trailer brakes, with the pressure difference across the restriction operating the trailer brakes, ie if the line to the trailer is cut then the hold-off brakes on the trailer are applied rapidly. The valve monitors the trailer and unit brake pressures and controls the trailer brakes in such a way that they are applied momentarily before the unit brakes ie the rate of brake application is faster on the trailer. After a set pressure is reached the rate of application is modulated so that braking stability is maintained.

Title: Pneumatic cloth-reed guide for a sewing machine - has a widening nozzle which induces a gentle suction
Inventor: HANNEMANN FRANZ
IPC: D05B35/10
Filed: 1976-07-17
Abstract: The sewing machine has a compressed-air nozzle to position the cloth sideways, by maintaining its edge in contact with a guide. The cloth lies above a plate contg. a shallow but widening depression into which compressed air is injected at the narrow end. This depression forms, with the cover plate above it on the other side of the cloth, a kind of expanding nozzle, which holds the edge of the cloth against its guide. The guide has hole(s) through which the compressed air escapes. The device is designed to avoid pressing the cloth too hard against the guide, and rucking the edge. There are pref. two depressions in the plate, one on either side, serving pieces of cloth placed respectively above and below it.
