Title: Method and Apparatus for Improving the Uniformity of Longitudinal Stretching in the Biaxial Stretching of Film Webs.
Inventor: ZYGAN HIERONYMUS
IPC: B29C55/14
Filed: 1969-01-15
Abstract: 1,193,051. Improving the uniformity of longitudinal stretching in the biaxial stretching of films. FARBENFABRIKEN BAYER A.G. 15 Jan., 1969 [26 Jan., 1968], No. 2292/69. Heading B5B. As shown in Fig. 1, a film travelling first over a positively driven feed roll 1 having a peripheral speed V1 and then over a draw roll 2 having a higher peripheral speed V2 is stretched longitudinally at a stretch ratio V 2 /V 1 . In order to obtain an indication of the degree of uniformity of the longitudinal stretching of the film, a straight line 3 at right angles to the longitudinal axis of the film and extending across the film is marked on the film before it is stretched. When the line has reached the position 4 it will still be straight but the series of short lines which have also been marked at regular intervals along the line 3 will have lengthened due to the longitudinal stretching of the film. When the portion of the film bearing the transverse mark is advanced through the stretching zone C, the mark may become curved as shown at 5, indicating that the central portions of the film parallel to the longitudinal axis of the film are being longitudinally stretched to a greater extent than the longitudinal " lanes " of the film nearer the edges of the film. This effect may persist when the marked portion of the film is advanced through the first cooling zone D the annealing zone E and the second cooling zone F, as shown by the curvature of the mark at 6. On the other hand, depending upon the mechanical properties of the film when passing through the zones D to F, the curvature of the mark may be reversed, as shown at 7. In the case of fibres in which the mark acquires the curvature shown at 7, the lack of uniformity of the longitudinal stretching of the film is compensated by using at the outlet end G of the stretching frame a roller of the type shown in Fig. 2 instead of a conventional cylindrical roller. If the mark acquires the curvature shown at 6, a roller of the type shown in Fig. 3 is used.

Patent GB-1017144-A (GB)
Title: Improved process for oxidising hydrocarbons
IPC: C07D301/32
Filed: 1964-01-20
Abstract: Saturated or mono-olefinic unsaturated hydrocarbons having 2-5 carbon atoms are oxidized to olefin oxides and/or aldehydes by reacting an excess of the hydrocarbon at elevated temperature with air or other oxygen-containing gas mixture, to give a gas stream from which unreacted hydrocarbon is removed by washing with a higher-boiling hydrocarbon leaving a gas stream containing the olefin oxides and/or aldehydes and a solution from which the unreacted lower hydrocarbon is desorbed by blowing with oxygen or an oxygen-containing gas mixture and returning the gas mixture containing unreacted hydrocarbon to the oxidation step. The preferred starting hydrocarbons are ethylene, propylene or butylene or C2-C3 hydrocarbon fractions. The absorption process is preferably carried out at room temperature or at a slightly lower temperature, e.g. at 10 DEG  C., and the desorption is conveniently carried out at a lower pressure than the absorption.  Suitable higherboiling hydrocarbons may be aromatic, aliphatic, alkylaromatic or naphthenic.  Examples are given of the oxidation of (a) propylene to propylene oxide and acetaldehyde, (b) ethylene to ethylene oxide, (c) butylene to acetaldehyde and acrolein; and (d) a mixture of propane and propylene to propylene oxide.

Title: Improvements relating to magnetic compasses
IPC: G01C17/00
Filed: 1944-02-10
Abstract: 586,191. Magnetic compasses. SPERRY GYROSCOPE CO., Inc. Feb. 10, 1944, No. 2491. Convention date, Feb. 28, 1942. [Class 97 (ii)] An apparatus for reducing the northerly turning error in a magnetic compass carried on a craft, comprises a magnetic-field compensating device and a shielding means for the device which are relatively moved by a turn indicator to apply to the magnetic needle the requisite correction. Fig. 1 shows the instrument panel 21 of an aircraft on which is mounted the. casing 20 of a magnetic compass with a pendulous compass card 22 supported on a jewel post 23 and bracket 24 and maintained in azimuth by magnets 25. The lower casing 31 encloses a bank indicator comprising a ball and fluid in the curved tube 30, the gyroscopic rate of turn indicator comprising a pneumatically driven rotor 35, the supporting frame 34 and disc 37 processing about an axis defined by the trunnions 32, 33 and the compensating device consisting of magnets 50, 51 fixed in an arcuate sleeve 52 and mounted by the arm 53 on the disc 37. Precession of the disc 37 against the action of the centralising spring 36 is proportional to the rate of turn, being measured by the movement of the pointer 41, the pin 42 engaging a slotted member 43 which controls the nuts 44 and causes the magnets 50, 51 arranged linearly so that the south poles are at the extremities to emerge from their shielding sleeve to exert their compensatory effect on the magnetic needle of the compass. By adjustment of the strength of magnets 50, 51 and their distance from the magnets 25, the compensating torque can be made proportional to the northerly turning error in any properly banked turn. If the craft crosses the magnetic equator, the polarities of the magnets 50, 51 must be reversed and the shielding plates 80, 81 are adjustable by the screw 82 and knobs 83 for change of latitude. In a modification the shield 54 is moved by precession of the disc 37 to uncover the magnets 50, 51 which are then arranged so that the north poles are at the extremities. In a further modification, the compensating magnets are mounted in a piston reciprocating in a cylinder to damp the oscillations of the gyroscope. Specification 103,530, [Class 97 (ii)], is referred to.

Title: Improvements in or relating to checking and control arrangements for facsimile telegr
Inventor: KIRCHEL ALAN ARTHUR
IPC: H04L21/00
Filed: 1951-02-02
Abstract: 693,593. Copying-telegraphy. MUIRHEAD & CO., Ltd. Jan. 16, 1952 [Feb. 2, 1951], No. 2681/51. Class 40 (iii). A checking and control arrangement for suspending the operation of a facsimile telegraph receiver until synchronism and phase conditions have been attained and for controlling the receiver in case of faults before or during transmission, comprises a spring-biased disc rotated from its normal position by the rotary motion of the apparatus and closing a series of contacts to effect the control operation, the disc being automatically released when it reaches its extreme position to return to its normal position. The disc 1, mounted on a shaft slidable in bearings 2, is rotationally biased by the spring 3 and is positively driven from the receiving drum 11 by a cam 10 and driving pawl 8 engaging teeth 7 which are also engaged by a retaining pawl 9. Arcuate ridges 12 of different lengths operate plungers 13 associated with contact sets 14 to effect the respective controls. If the receiver is not in correct operating condition, contacts closed by a projection 1a operate a supervisory control which through a further contact set 14 operates a failure alarm at the transmitter and stops the receiver. If a failure occurs during the transmission of the material, the " end-of-message " signal will not be received to reset the timing disc and to stop the receiver. In this case the timing disc is rotated beyond its " end-of-message " position and closes a restoring contact-set which operates the failure alarm at the transmitter and energizes the reset magnet 15 to release the timing disc 1. The return of the disc 1 to its initial position, with a pin 17 against a stop 4, is cushioned by a spring-pressed damping ring, and the circuit of the re-set magnet 15 is spaced in the normal position of the disc 1.
