Patent DE-2419525-A1 (DE)
Title: Coke oven scraper mechanism - has lateral and facing blades movable on collapsible insertion frame
Inventor: KONNO NAGAYOSHI
IPC: C10B43/04
Filed: 1974-04-23
Abstract: A scraper mechanism to keep the door sealing and door proximity faces of coke ovens of the horizontal chamber type free from deposits includes a first set of blades which can be mechanically moved up and down over the door seals. A frame which can be collapsed and, after insertion into the chamber opening, splayed open, carries a second set of blades which are coupled to the first set and scrape the proximity faces clean. An inner heat screen protects the whole scraper mechanism during its operation on a still hot oven chamber. The scraper mechanism can be readily inserted and removed without damage to its own parts or to the chamber parts. All parts where tar can be deposited are reliably kept clean, the modest force exerted by the blade springs cannot damage the surfaces. Stops ensure the proper alignment.

Title: Knitted fabrics for coating with expanded polyurethane - having the low stretch and other props of woven fabrics
Inventor: KERSHAW RONALD
IPC: D04B1/00
Filed: 1974-08-13
Abstract: A fabric with a controlled predetermined degree of stretch, for coating with a synthetic matl. is tubular knitted on a circular machine, the yarn being fed positively from lateral spools so as to deliver a predetermined length of yarn for each stitch, at a controlled tension, thus fixing the stretch lengthways, whilst a pile thread is also laid in to restrict the transverse stretch. The fabric after inspection, is dyed, dried, raised and sheared before being slit and the raw edges impregnated to form selvedges. The width is set by running through a stenter before rolling up and the fabric is then transferred to the coating machine. Limiting the stretch characteristics yields a fabric which supports the expanded polyurethane coating without damaging it during use.

Title: Winter tyre with two lateral oblique tread rings - with reduced swing-out of vehicle on bends without damage to roadway
Inventor: BERGMANN HEINZ
IPC: B60C11/00
Filed: 1976-03-05
Abstract: Winter tyre comprises two tread rings arranged on the tyre carcass, for maintaining the vehicle in its tracks in conditions of ice and snow. In good road conditions lateral forces are taken up by the central tread profiles, preventing the vehicle from swinging out sideways on bends. The laterally obliquely extending tread rings are displaced laterally. In conditions of ice or snow, lateral forces are not taked up by the central tread profiles and the vehicle can swing out on bends. Swinging out is reduced to a considerable extent by the lateral oblique arrangement of the tread rings. The tread rings are pressed into the ice or snow.

Title: Press. regulating valve for turbine gland steam - has throttled hydraulic oil flow through valve positioner
Inventor: DEINLEIN-KALB HANS
IPC: F01D11/06
Filed: 1976-04-27
Abstract: Live steam enter a press. reducing alve (34) from a flow connection (32) and leaves through passages (30, 31) to turbine labyrinth glands. The valve is moved by a piston (12) which is moved by hydraulic press. in a positioner chamber (28). Oil enters through a throttle (25) and flows past the underside of the piston through a valve (14) into a membrane chamber (18). It leaves this through a second throttle (19) and flows through passages (27, 29) to the upper side of the piston. The other side of the membrane (16) is subjected to the steam press. (5) from the glands. The regulation of the oil press. acting on the steam valve by the valve (14) in the base of the piston results in a better regulation of the gland steam press.

Title: Measurement of fuel flow for IC engine - particularyly for diesel with excess fuel feedback and involves auxiliary reservoir
Inventor: AKIYAMA ISAO
IPC: G01F15/06
Filed: 1976-07-27
Abstract: The mechanical and electrical network is for measuring accurately the fuel flow to an internal combustion engine, typically a diesel, equipped with excess fuel feedback. The fuel flows from the fuel tank (11) to the measurement device (23) and thence through a pipe (12) to a low pressure pump (13), a high pressure pump (17) and a valve inlet (19) in that order. Any excess fuel is delivered back not to the tank (11), but to an auxiliary reservoir (24) inside the fuel measurement device (23). The flow of this device from the tank thus represents accurately the rate of fuel consumption by the engine. A number of chambers, pumps, valves, a float (45) and associated switches and electronic logic networks (32, 36) are included.
