Title: Improvements in and relating to polypropylene and other linear polyolefin films
Inventor: JENNINGS BRIAN EDMUND
IPC: B29C55/20
Filed: 1961-05-25
Abstract: <PICT:0928265/IV(a)/1> A biaxially oriented polyolefin film is passed on a stenter through an oven at a temperature of 120 DEG -160 DEG C. and allowed to shrink transversely before the stenter clips grip the film. Longitudinal shrinkage may also be allowed before the film is gripped.  The film may be positioned by means of one or more jets of air on one surface of the film and one or more jets of air or a stationary guide on the other surface.  The polyolefin may have been stretched at a stretch ratio of 5-10 to 1 in each direction. The film is heat-set and freed from wrinkles by the treatment. The treated film may have a longitudinal thermal shrinkage of less than 6% and a transverse thermal shrinkage of less than 2% measured at 120 DEG C. and a tensile strength of at least 18,000 p.s.i.  The polyolefin may be polythene, polypropylene, or polybutene-1.  As shown, film from a roll 1 is passed over a roller 2 and fed between stenter clips 3, by means of air jets 4 and 5 positioned above and below the film, into a stenter oven 6. The stenter clips are designed to close after a certain shrinkage of the film (Fig. 2, not shown).

Abstract: 938,007. Transistor oscillator circuits. ERICSSON TELEPHONES Ltd. Sept. 6, 1960 [June 6, 1959], No. 19423/59. Class 40 (6). Telephone ringing currents are generated in a circuit comprising two transistors and a transformer which in operation saturates and means are provided for eliminating transient voltages resulting from the switching action of the transistors. The oscillator shown in Fig. 2 is of the type in which current build-up is limited by saturation of the core of the transformer and in which oscillation is initiated by the circuit 25, 26 and 27. Transients are eliminated by the circuit 19, 20 and this circuit is so connected to the main on-off switch 30 that when the generator is switched off the elements 19, 20 are connected across respective halves of the transformer to prevent the generation of excessive oscillatory currents. In Fig. 3, switching transients are eliminated by capacitors 23 and 24. The supply voltage is excessive for the transistors used and accordingly a voltage dropping resistor is connected in the supply circuit. Diodes 36 and 37 limit the collector voltage swing. According to the Provisional Specification transient voltages can alternatively be eliminated by non-linear resistors connected between the collector electrodes.

[Also in Division H1] The negative resistance exhibited, due to Gunn effect, when an appropriately constituted and demensioned semi-conductor sample is subjected to a sufficiently high electric field can be modified by radiation incident on the layer; but in use of such a device to measure radiation intensity, false indications can arise due to stray radiation. To avoid such false indications the invention proposes coating a Gunn effect sample with a radiation excluding substance which is either (a) transparent to the radiation to be measured but opaque to other radiation or (b) opaque to all radiation but has a transparent window. In the latter case the source of radiation to be measured is so positioned that this radiation impinges directly on the window area.

Title: Process for the production of amino-alkyl esters of aminohydroxybenzoic acids
Filed: 1952-08-01
Abstract: Aminoalkyl esters of aminohydroxybenzoic acids are prepared by reducing a halogenalkyl ester of a nitrohydroxybenzoic acid to the corresponding ester of an amino-hydroxybenzoic acid, and then reacting the ester so formed with a primary or secondary amine.
