Patent DE-3046440-A1 (DE)
Title: Instrument precision gear wheel - has teeth cut while already fitted on its shaft in its bearings to minimise tolerance errors in use
Inventor: JAKOB LUDWIG ING GRAD
IPC: B23F23/06
Filed: 1980-12-10
Abstract: The arrangement is intended for cutting a gear wheel (1), such as may be used in a measuring instrument, and minimises rotational, centralising and pitch errors due to tolerances when assembling the cut wheel on a shaft in a bearing. To this end, the blank is assembled on its shaft (2) before cutting with a hobbing cutter (7) and the shaft is carried in the actual bearings (3) with the bearing housing (4) in which it is to be finally used. During cutting, the shaft is driven by the spindle (6) of the gear cutting machine via a torsionally rigid but axially and radially resilient and misalignment absorbing coupling (5).
Patent DE-3100530-A1 (DE)
Title: Radiant heater
Inventor: SANDER WALTER
IPC: F24C1/08
Filed: 1981-01-10
Abstract: A radiant heater has a tubular radiation screen (17) which is arranged with a vertical axis and in the inner space (18) of which at the lower end a burner nozzle (19) is arranged. The radiation screen (17) is produced from a metal sheet, from which a large number of identical beads (22) forming air passage openings (23) is pressed out. In this manner, the radiant heater can deliver as great a quantity of heat as possible to its environment to all sides. The fresh air necessary for the combustion can flow into the radiant heater without large flow losses occurring, so that it is no longer necessary to use a fresh-air blower. <IMAGE>

IPC: C07D249/06
Filed: 1981-02-23
Abstract: A process for the preparation of <IMAGE> in which R1 denotes hydrogen, optionally substituted phenyl or alkyl having 1 to 3 C-atoms, R2 denotes hydrogen or a group of the formula <IMAGE> , in which R3 represents alkyl having 1 to 6 C-atoms or optionally substituted phenyl, R4 denotes alkyl having 1 to 4 C-atoms or optionally substituted phenyl and R denotes optionally substituted phenyl, is described which consists in the reaction of a 2-phenyl-2H-1,2,3-triazole oxide of the formula <IMAGE>  with an acid halide of the formula <IMAGE> , in which X denotes chlorine or bromine, in an organic solvent in the presence of a tertiary amine. If desired, <IMAGE> groups in the 4-position of v-triazoles obtained in this way can be hydrolysed to -CH(R1)OH groups. The 2-phenyl-2H-1,2,3-triazoles described, which are for the most part novel, can be used as starting materials for the preparation of optical brighteners of the v-triazole series.

Title: Device for assisting the change in direction of rotation in SZ-stranding machine drives
Inventor: OLBRICH RAINER DIPL ING
IPC: H01B13/02
Filed: 1981-03-30
Abstract: The invention relates to a device for assisting the change in direction of rotation on SZ-stranding machines. The aim of the invention is greatly to reduce the high motor loads and to avoid damage to the drive system. The object according to the invention provides for developing a device which briefly stores the entire rotational energy and which briefly discharges it again with the effect of the change in direction of rotation. The solution for achieving this object contains a device which consists of a control shaft arranged rotatably in bearing stands and of an auxiliary shaft likewise mounted there, the control shaft being driven by a motor and being connected to the auxiliary shaft via a positive step-up transmission and to the stranding apparatus via a driven journal. The control shaft has, on the two end faces, fixed stops with engagement pins. The auxiliary shaft is provided at the ends with angularly adjustable mountings, in which radially displaceable guide pins with stop rails are mounted and are loaded via compression springs. When the engagement pin comes into contact with the stop rails, the compression springs absorb the entire rotational energy and discharge it again.
Patent DE-3115183-A1 (DE)
Title: Shifting clutch with torque converter
Inventor: MAGG ALFRED
IPC: B60W30/18
Filed: 1981-04-15
Abstract: In a shifting clutch with a torque converter in the chamber shared with a synchronised intermediate transmission gear, which is closed by way of a simple control of pressure medium and lubricant from the system and opened by spring force and in which the plates are lubricated and cooled, the control for a smooth shifting to a new gear occurs in the shifting clutch itself as a function of the driving conditions. The admission is therefore possible by a simple open/closed switching and occurs either in a double function from the gear shift device or, if a double clutch is used as shifting clutch in semi-automatic or fully automatic mode, it may be controlled in relation to the gears to be selected, for example on the basis of the speed. Lubricant and coolant are admitted only during the actual closing process so that the shifting clutch is in principle dry both in the opened and in the closed state. <IMAGE>

Title: Boot, in particular ski boot
Inventor: LEDERER JOSEF
IPC: A43B5/04
Filed: 1981-12-04
Abstract: In a ski boot with an air cushion bladder and inflation device, it is proposed that a filling and emptying valve of the air cushion bladder is covered by a pump diaphragm which has a hole. When the pump diaphragm is pressed together, the hole is closed by the pressing finger and the air in the pump diaphragm is compressed until the finger opens a valve body of the valve. Then, the compressed air flows into the bladder. To let the air out of the bladder, the finger is likewise applied over the pump diaphragm on the valve body in order to open the latter, the opening in the pump diaphragm now, however, being left open.

Abstract: A housing for a burner, operated with hot air, for glass melting furnaces, heat treatment furnaces or the like, consists of a pot which is arranged on a burner plate (2) and is provided with thermal insulation (7, 10), the bottom (14) of which is passed through by a nozzle connection and on which a connection piece (6) for a hot-air supply line is provided. A burner housing is to be produced, which, even with outer thermal insulation, reliably withstands preheating air temperatures of approximately 800 DEG C in spite of additional heat supply from the furnace body. Additionally, the burner housing is to be economically manufacturable and more easily adaptable to the conditions at the installation site. To achieve this aim, it is envisaged that the housing is formed in a multipart manner from a sheet-metal casing (1), from a tubular moulded body (7) made of heat-resistant material which is insertable in the sheet-metal casing (1), from a cover (10) which can be located on the rear end of the moulded body (7) and is moulded from heat-resistant material, and from a front metal nozzle connection plate (14). <IMAGE>
