Patent DE-2523664-A1 (DE)
Title: Subsequently applied door or window synthetic rubber sealing - is inserted in prefabricated shaped battens and is for sound and heat insulation
Inventor: KRUEGER GERHARD
IPC: E06B7/23
Filed: 1975-05-28
Abstract: The sealing units are designed for subsequent application to existing doors and windows of any type. They consist of prefabricated synthetic rubber seals, with lipped or hollow profile pieces, drawn into prefabricated shaped battens, which are applied to windows, doors or frames. The return force in these shaped battens effects an optimal sealing action, which reduces heat loss and noise transmission. Synthetic rubber clip shaped sealing units may be inserted by cutting grooves in the windows or doors. The shaped battens may be made of wood, metal or plastic. The process can be easily and inexpensively applied to any existing windows or doors, using simple prefabricated units; and it is effective in all weather conditions.

Title: Vacuum pipe joint - by rubber disc on one sealed by vacuum against bell mouth on other pipe end
Inventor: WEWERS HERIBERT
IPC: C10B41/08
Filed: 1975-06-27
Abstract: Pipe sections with an internal vacuum which have to be safeguarded against explosions (joints of blowers and scrubbers on coke charging cars) are sealed at their joint by an elastic disc which is held at the end of one pipe by a welded angle iron ring and a flat ring. The other pipe section has a conically widened bellmouth end against which the elastic disc is held by the internal vacuum. In case of deflagrations in the charging gas extraction pipe system caused by entrained hot particles, no damage is done to the structural parts because the pressure is released immediately. Danger to personnel by flying projected parts is eliminated.

Title: Infinitely variable spur gearing with segmented gear - uses eccentric rotor to control angular speed of individual segments
Inventor: KELLER ROMAN ING GRAD
IPC: F16H37/12
Filed: 1975-07-28
Abstract: The infinitely variable spur gearing comprises a train of three gears (1, 3, 4) having parallel axes lying in a common plane.

The segments have respective radial slots (8) engaged by respective axial rods (9) arranged axisymmetrically on a rotor having an axis parallel to those of the gears. The angular speed of the individual segments changes during movement from the first to the third gear according to the eccentricity of the rotor relative to the axis of the common shaft. To vary the transmission ratio, the rotor position is adjustable in the common plane of the gear axes.

Title: Nonskid silicone rubber coatings - applied to surfaces like carpets or china from moisture hardening silicone rubber compsns.
Inventor: BAUST EBERHARD
IPC: B05D5/00
Filed: 1975-07-30
Abstract: Non-skid coatings are applied from coating compsns. contg. a thermoplastic silicone rubber compsn. which can be stored with exclusion of water but hardens to elastomers at room temp. in the presence of water.

Patent DE-2546685-A1 (DE)
IPC: G07D5/00
Filed: 1975-10-17
Abstract: To test a coin, the latter is moved through the controlled alternating-current field of a sensing coil (11) and from the difference between a reference voltage and the measured oscillator voltage which is changed due to the influence of the coin (1) on the alternating-current field, a controlled variable is formed by means of a differential circuit (18) which variable corrects the measured oscillator voltage to the voltage ratio between measured oscillator voltage and reference voltage which existed before the beginning of the coin measurement, via an influencing element (14) influencing the output voltage of an oscillator circuit (12). The controlled variable is used as criterion in the testing of the coin in such a manner that it is determined by means of a monitoring circuit (20) whether this controlled variable has reached a value which is located between an upper and lower limit. <IMAGE>

Title: Coarse gas purification - by scrubbing and regenerating washing medium by heat exchange cooling, pressure release and stripping
Inventor: JAKOB FRITZ
IPC: C10K1/16
Filed: 1976-11-26

Title: Distillation of high melting point metals and alloys - in plant combining plasmatron with vaporising and cooling chambers
Inventor: CSERNAVOELGYI LASZLO DIPL ING
IPC: C22B5/16
Filed: 1977-04-07
Abstract: In the distn. of metals and the sepn. of alloys, a plasma mixt. of natural gas and oxygen or air is formed. The mixt. is ignited to form a plasma beam through which divided metal is projected and the vapourised metal is cooled and set under controlled conditions. The natural gas used is rich in inert gas cpds, esp. CO2. Before the plasma mixt. is formed, hydration water is removed from the otherwise untreated natural gas. The metal vapour formed in the plasma is passed through cooling chambers alongside each other, the walls of which are cooled to a definite temp. corresp. to the pts. of the components of the vapour. The plasma mixt. is ignited by an electrode which is cooled by the circulation around it of natural gas to be mixed with the oxygen or air, and in this manner it is preheated. Metals melting at high temps. and having a high degree of purity are produced, and sepn. of metal is allowed without complicated appts. and with low electrical energy consumption.
Patent DE-2720766-A1 (DE)
Title: Additional guiding edges for skis - provide extra control for sharp high speed turns and can be fitted to existing skis
Inventor: WINTERSBERGER LUTZ
IPC: A63C5/048
Filed: 1977-05-09
Abstract: High performance skis suitable for making sharp turns at high speed have additional guiding edges which extend the whole length of the ski. These second edges are smaller than the primary edges and lie outside them so that they are normally clear of the snow and only come into action when making a sharp turn. They have, however, the disadvantage of reducing the flexibility of the ski. By making the guiding edge extend for only the length of the skier's foot, the effectiveness of the edge is still maintained but without loss of ski flexibility. In addition these guiding edges can easily be added to existing skis. They can have a stepped formation.
