Title: Gas cut off valve for oxygen cylinders - handwheel turns two components with different thread angles
IPC: F16K1/30
Filed: 1973-06-30
Abstract: The valve allows speedy release of gas. The mechanism consists of a valve spindle with sealing plate fitting against a seating in the housing.

Title: Weighing device with electromagnetic force compensation - has permanent magnet with compensation coil and resistor network with temperature compensation
Inventor: BERG CHRISTOPH DIPL PHYS DR
IPC: G01G7/04
Filed: 1974-01-09
Abstract: The load to be weighed is applied to the compensation coil. The device comprises further an indicator for the compensation coil zero position. A control amplifier for a signal delivered by the indicator, whose output current is applied to the compensation coil, tends to hold the coil in its zero position; this current is a measure for the load. The permanent magnet has an additional correction coil which corrects the magnet field strength changes due to the compensation current. Its temperature variations are compensated by a resistor network with a temperature sensitive PTC resistor. The correction coil itself serves as the temperature compensation resistor and its material is a metal having good electrical conductivity.

Title: Sorbitan-wool wax acid esters, emulsifying agents - for water in oil emulsions
Inventor: WENDLER INGRID DIPL CHEM
IPC: C09K23/00
Filed: 1974-03-20
Abstract: Sorbitan- wool wax acid esters are used as emulsifying agents in the production of water-in-oil emulsions.

Title: Quick-setting highly viscous plastics mixed and degassed - using film flow to eliminate bubbles quickly
IPC: B01F15/00
Filed: 1974-04-09
Abstract: A method of, and device for, mixing and degassing quick setting, multi-component plastics contg. fillers consists of first mixing by means of revolving blades, then conveying the mixt. up a central, vertical tube by a propelling screw, the matl. emerging at the top of the screw then flows as a thin layer down a sloping flange along the top of the tube, and thus executes a continuous cyclic motion within the vessel. This is continued until the discharge valve at the bottom of the vessel is opened and simultaneously the screw direction of rotation is reversed. Esp. for mixing quick-reacting, highly viscous plastics, where the reaction time does not permit through mixing to get rid of the bubbles in the mixt. The use of a flow of the matl. as a thin film down the inclined flange brings the bubbles to the surface much more rapidly and enables a completely bubble-free mixt. to be obtd. before reaction sets in.

Title: Large diameter hollow boring tool - leaves inner core during cutting process
Inventor: BORCHERT OTTO
IPC: B23B51/04
Filed: 1974-04-26
Abstract: The boring tool consists of a tube at the end of which several disposable triangular cutter bits are mounted. The tool is driven round at a power of 8 to 10 Kw and leaves an inner core during the cutting process. The cutting edges are mounted on planes which pass through the centre line of the boring tool, e.g. three cutters are used which are not equally divided over the circumference of the tool, so that there is a resultant force which pulls the tool to one side. Supports are mounted inside the tube so that the boring tool is guided by the central core. When several cutters are used, each next cutter is placed on a larger radius, so that all cutters have equal cutting action.

Title: Holding down anchor bolt removal process - heats locally to weaken before breaking under tension load
Inventor: FISCHER JOACHIM
IPC: E02D5/76
Filed: 1974-06-14
Abstract: The process is for use with free steel portion of a holding-down bolt fitted in a buried anchor body for temporary use. When the bolt is no longer required, a definite breaking point is produced in it, and it is placed under tension load until breakage takes place. Typically this can be achieved by local heating, e.g. to red heat, to soften it, using a charge of thermite powder in a sleeve fitted round it, or an electrical heating coil. the design avoids the need for unscrewing the bolt - which may be difficult due to it having rusted up - weakening it before insertion in the first place, or the use of inserted cutting tools.
Patent DE-2437541-A1 (DE)
Title: Piezoelectric device for speed control - has cooling fan to provide pressure variation to limit speed of electric motor
Inventor: STILTZ ERWIN DIPL ING
IPC: H02H7/093
Filed: 1974-08-03
Abstract: The apparatus uses the pressure developed by the fan to operate a piezoelectric device which issues a signal to amplifier which in turn operates a relay to strengthen the field and/or increase the armature resistance and/or disconnect the motor from the supply. The switching operation can be performed by an orthodox dopper type relay or by transistors. The elements are of the piezoelectric type and the fan can be axial or radial. The amplifier is so chosen that when the motor exceeds a certain speed an adjustable resistance is connected in parallel to the motor field and at a higher value operates another relay with a time delay to disconnect the motor from the supply.
