Title: Synchro control for heavy vehicle transmission - has coil spring shaft brake linked to clutch to reduce speed of spinning gear members
Inventor: GARTNER HELFRIED
IPC: F16H3/12
Filed: 1979-07-04
Abstract: The synchronisation control for a heavy transmission has a servo brake for the transmission parts, operated by an hydraulic control valve linked to the clutch pedal. The link between the clutch pedal and the valve is a spring wound around the clutch pedal pivot and striking the valve with its free end. The spring tightens on the clutch pivot shaft when the clutch is depressed and lifts the valve plunger with its free end. When the clutch is released the spring pressure releases and the free end strikes a stop and is held there. The loose coils slide over the shaft so that a self adjusting effect is obtained as the clutch wears.

Title: Centrifugal application of concentrated dye-liquors to loose fibre - giving rapid controlled uptake with low residual moisture content
Inventor: MUEHLEN ROLF
IPC: D06B5/26
Filed: 1979-09-19
Abstract: Dyestuff is applied to loose fibre with extremely short liquor ratios and high dyestuff concentrations by a centrifuging process, to an uptake of 15-100 wt.%. Excess liquor may be applied to the fibre in a hydroextractor, the unused portion being immediately expelled by the centrifuging. The uptake ratio can be controlled by varying the centrifuge speed and treatment time. The process gives rapid, uniform uptake of liquor, and simultaneously reduces the residual moisture content to 15-100%, which prevents migration and also considerably reduces energy costs for fixing and drying.

Title: Plastics pipe for underfloor or panel heating - has external metal facing to prevent oxygen diffusion into water
Inventor: HEWING BERND
IPC: F24D3/14
Filed: 1980-03-06
Abstract: Plastics pipe for fluids, intended esp. for underfloor heating and other heating panels, has an external metal facing, substantially thinner than the pipe wall. Pref. the thickness of the metal facing is up to 50 microns. The pipe may be of ABS polymer, polyethylene, polypropylene, polybutene, or more specifically cross-linked polyethylene. The metal facing is pref. aluminium, copper, nickel or chromium, or various layers of different metals. Useful esp. for water heating systems where a frost-preventing additive is contained in the water. Plastics pipes used for this purpose are permeable to oxygen, which consequently diffuses through, dissolves in the water and can then cause corrosion at metal components in the heating plant. By externally facing the pipe with metal, as described, this oxygen diffusion is prevented.
Patent DE-3008669-A1 (DE)
Title: Exchange of data between central control and trains on parallel tracks - uses modified data sequence for each track to prevent cross talk between tracks
Inventor: LANGE HANS-ARMIN DIPL ING
IPC: B61L3/22
Filed: 1980-03-06
Abstract: The proposed data transmission arrangement is to prevent interference between parallel data channels laid between parallel sets of rails. These data channels are for the exchange of information and transmission of instructions, between a central control station and trains on the tracks. Data is transmitted in the form of a pulse coded telegram requiring a correct response from the receiver before further action can be taken. In order to discriminate between the correct signals for a track and cross talk from the neighbouring track, the check or switching instructions occur at different points in the telegram for each track. Typically the required displacement is achieved by transmitting to both tracks with a defined and locked phase displacement between them. The probability of acting on erroneous information is very low.

Patent DE-3109266-A1 (DE)
Title: Hollow moulded part which can be fastened by a rear-side adhesive layer
Inventor: OZAWA ISAO
IPC: F16F7/00
Filed: 1981-03-11
Abstract: In the case of a moulded part having a body which has a front side, a base, side parts and a cavity and can be fastened, by means of its base, on a underlying surface by an adhesive layer, the base is provided with at least one protrusion which protrudes into the cavity in the direction of the front side and is separated from the relatively thin side part by a chamber. When a pressure is exerted onto the front side in order to attach the moulded part adhesively onto the underlying surface, this pressing force generates, via the side part, a torque, around the lower end of the side part, which acts on the base and generates a positively directed surface pressing, and, at the same time, the force which the front sides exerts on the upper end of the protrusion generates a contact-pressure distribution which is at a maximum at the location of the force-exerting direction and becomes smaller towards the sides. The two contribute to the contact pressure, with the result that a secure and fixed adhesive bonding is ensured.
