Title: Awning drive for manual or power actuation - has locking wheel which is actuated from outside housing
Inventor: ERB WALTER
IPC: E04F10/06
Filed: 1973-11-13
Abstract: This drive is used for winding up the awning into the stowage position or for lowering the awning into the use position. The locking gear wheel ensures that the awning can be lowered only to an extent determined by the setting of this locking gear. The awning reduction drive between the drive shaft and the driven worm gear has locking bevel gears which are actuated from outside the housing by an adjusting head with a slot. The bevel gears are engaged with teeth of the bevel gear held on the worm gear. The gearing is erreversible so that the awning cannot come down out of control.

Title: Stored video signals reproduction device - uses disc rotating on air cushion at speed of e.g. 1500 rpm
Inventor: KROLL GUENTER DIPL ING
IPC: H04N5/76
Filed: 1973-11-15
Abstract: Signal recorder in a spiral track is red out by an optical system and converted by a photodetector into an electric signal. Two drives are provided, one for the disc and the other, designed as a servomotor, for the scanning system movement. The electric signal passes through an amplifying and coding stage, and is applied an f.m. demodulator to a stage delivering the video signal and also deriving a synchronisation pulse as reference signal for the servomotor. Signals delivered by the magnetic head system are applied through an additional equaliser-limiter stage to the f.m. demodulator. A colour picture blanking, composite synchronisation signal is available at the output of the first of the signal delivery stages, and the sound signal at the output of the second.

IPC: B29C48/94
Filed: 1973-11-15
Abstract: Prodn. of plastic tubes of the type in which a quasi-liq. pre-form is extruded from an extrusion nozzle with a mandrel and is drawn away over an inner calibrating mandrel attached to the extrusion mandrel and cooled thereon from the quasi-liq. state while introducing a lubricant between the pre-form and the inner calibrating mandrel. Comprises introducing in the quasi-liq. zone of the pre-form a hydraulic lubricant under practically zero pressure into a space between the extrusion and inner calibrating mandrels, so that (i) the pre-form entrains a layer of lubricant between it and the inner calibrating mandrel and (ii) this lubricant layer is broken down in wedge-shaped longitudinal section by radial forces acting on the pre-form. Method provides continuous lubrication while not tending to drive the lubricant into the plastic.

Title: Two stroke I.C. engine - has catalytic disc to divide combustion chamber
Inventor: BOENSCH HELMUT WERNER
IPC: F02B19/12
Filed: 1974-01-19
Abstract: A separating disc provided with one large opening and a number of small openings and consisting of or coated with a catalytic material, is fitted between the cylinder top and the cylinder head which divides the combustion chamber into two separate parts. The cylinder head contains a combustion chamber off set in relation to the cylinder axis. A fuel injector as well as a spark plug.

Title: Thermometer arrangement - with bimetallic thermometer and mounting facility, has pins corresponding to suction cups
Inventor: BOUEKE-LEPA GEB LEPA PAULA
IPC: G01K1/14
Filed: 1974-03-19
Abstract: The thermometer dome has a number of pins which correspond to the suction cups. In the webs of the suction cups there are holes or recesses of such dimensions that the pins can be accommodated in them with a friction fit. By virtue of the suction-cup ring it is possible to fasten the thermometer arrangement to any smooth base surface, the webs making a space between the thermometer element and the mounting surface. It can, therefore, be placed inside refrigerators, deep-freeze cabinets etc., taking up very little space, precisely at the point where a specific temperature value is to be measured and monitored continuously.

Title: Aluminium alloy surface treatment - by electron beam fusing of harder metal and machining to expose resistant surface
Inventor: HILLER WALTHER DIPL ING
IPC: B23P13/00
Filed: 1974-03-30
Abstract: Workpieces of aluminium or aluminium alloy receive a surface layer of V, Cr, Mn, Fe, Co or Ni which is fused in such a way that the alloy produced consists of a matrix, rich in Al, with a fine distribution of metallic phases of high hardness, as in the Parent Patent. Surfaces which are not directly amenable to this process can be fashioned by subsequent machining during which a part of the alloy produced is removed. This will expose an area which originally lay within the alloy volume and which may be at right angles to the original plane of application. This widens the scope of the parent patent to the prodn. of surfaces such lubrication grooves or shoulders which are not very accessible or difficult to treat.

Title: Dust extractor for tunnels and headings - has water sprayed in precipitators on both sides of centre fan
IPC: E21F5/20
Filed: 1974-09-13
Abstract: Dust extractor for tunnel and heading operations is constructed or mining sectors consists of a central fan combined on intake and delivery sides with a set precipitator. To bring the level down below dew point in the precipitator water is sprayed on the intake side, and the dew point further under shot by spraying water in the precipitator on the delivery side likewise. Noise reduction is obtained in that the deduster generates twisting flow patterns on intake and delivery sides. As these flows enter and leave the fan they are converted into ideal flows by the action of air rectifiers provided for the purpose.

Title: Electrical contact materials contg cadmium oxide - to increase brittleness of contact welds and eliminate high energy electrons
Inventor: DAVIES TERRENCE ARDERN
IPC: H01H1/025
Filed: 1974-12-10
Abstract: A material for electrical contacts is composed of a matrix of Cu, which can be replaced by Ag to leave >=0.1 wt.% Cu, and 2.5-20 wt.% CdO finely dispersed in the matrix. The material is made by mixing coarse powders of the matrix material which have a particle size greater than 0.044 mm with CdO powder angstroms 1 mu, compacting and sintering in an inert atmos. CdO is uniformly distributed and increases the brittleness of the points where welds occur when an electrical contact is formed. Cd vapour in the electric arc which occurs when the contact is broken reduces the average electron energy of the arc and changes the distribution of the electron energies so that high energy electrons are eliminated.

Patent DE-2509256-A1 (DE)
Title: Pressure generating cylinder for hydraulic systems - has rotating disc on suction side and stationary discharge disc
Inventor: GOERES HANS DIETER WILHELM
IPC: F03G7/10
Filed: 1975-03-04
Abstract: The cylinder has a suction end and a pressure or discharge end. A rotating disc near the suction end has a very smooth surface on the side away from the end and a rough surface facing the suction end and by carrying with it the liquid between itself and the end it produces a drop in the static pressure in this region. The smooth upper surface does not carry liquid with it. Longitudinal blades project from the discharge end and reach almost to the rotating disc but do not touch it. These also help to prevent rotation of the liquid between the disc and the discharge end. A pressure difference is therefore established between the two ends of the cylinder.
