Patent DE-2364412-A1 (DE)
Title: Thermoplastics sheet continuously pressed onto chipboard - by hot roll which it contacts simultaneously with chipboard
Inventor: ETTEL HUBERT
IPC: B27N7/00
Filed: 1973-12-22
Abstract: A press for continuously applying a thin thermoplastics sheet onto a thin band of chipboard, comprises a heated roll around which these are passed under the pressure of an endless belt acting over a portion of the roll circumference. The chipboard band and thermoplastics sheet are both fed into the gap between heated roll and belt by curving them around the belt and its guide roller and not around the heated roll; the gap between heated roll and belt is equal to the combined thickness of chipboard and thermoplastics. The thermoplastics sheet does not approach the heated roll until the latest possible moment; this prevents it from becoming overheated before it is pressed against the chipboard.

IPC: H03K17/73
Filed: 1974-04-09
Abstract: The push-button timing switch is intended for temporary quenching of a thyristor, contained in a system which has a thyristor tetrode for the system thyristor restarting. In the thyristor quenched condition a resistor-capacitor element is charged. When a preset voltage has been attained at the capacitor, a transistor becomes conductive and ignites the thyristor tetrode which discharges the capacitor for igniting the system thyristor. The voltage generated at the thyristor in quenched condition forms the voltage source for the entire circuit. Preferably the system thyristor cathode is connected across a resistor to a reference voltage, the resistor being so rated as to conduct the current required for the system thyristor switching.

Title: Accurate gas dilution for analysis using permeable membrane - with accurate temp control of gas flows on both sides
Inventor: LUCERO DANIEL P
IPC: G01N33/00
Filed: 1974-06-07
Abstract: A device for carrying out an accurately controlled permeation of a first fluid into a second, esp. for accurately diluting a gas in another carrier gas e.g. air to enable analysis to be carried out, comprises a permeable diaphragm mounted transversely in a housing so that the specimen gas can permeate through the diaphragm into the carrier gas. On each side of the permeable diaphragm there is a feed-and-return system for the specimen gas and carrier gas respectively. The specimen gas passes along a very shallow annular space, where its temp. is brought to an accurately controlled level by external heaters, then flows radially inwards across the face of the diaphragm and leaves the diaphragm chamber through a return line. On the other side of the diaphragm, a similar process takes place with the carrier gas, e.g. air, flowing along a shallow annular space, also with external heaters, then radially inwards to return through a line. In a preferred embodiment, each half of the system is virtually identical to the other and constituted of an external cylinder and an internal cylinder connected together at flanges with slight radial clearance between them to constitute the annular passages. The two halves are clamped together with the diaphragm in its support between them. A wide range of dilution ratios under highly accurate control and uniform temperature conditions is achieved.

Title: Tape for sliding clasp fastener - uses non-woven materials
IPC: A44B19/34
Filed: 1975-01-11
Abstract: Tape for sliding clasp fastener is distinguished by the unordered position of the constituent parts forming the tape and sliding clasp fastener with this tape. Lower cost by substituting non-woven materials in the manufacture of the tape instead of conventional woven or knitted materials. The tape can be in textile materials with random arrangement of the fibres or in plastic foam. According to the kind of fibres, they can be felted together or with the use of thermo-plastic synthetic fibres they can be anchored together by heat treatment. As the fibres are usually subjected to mechanical stress during manufacture namely tension, they re-act on heating by a relaxation of their structure which expresses itself in a lengthwise shrinking with transverse expansion inside the fibres. This enables it to be used to advantage in the anchoring previously mentioned. With further heating the fibres become soft and a bonding or adhesion takes place.
