Title: Improved means for connecting overhead high tension electrical cables to the insulators of transmission towers
IPC: H02G7/05
Filed: 1959-04-27
Abstract: 889,961. Supporting cables. FRASER, H., and CANTLAY, W. G. Nov. 27, 1959 [April 27, 1959], No. 14240/59. Class 36. A suspension unit for connecting a cable to an insulator comprises an upper part 12 and a lower part 10, 11, the lower part being so supported by the upper that if the cable breaks the lower part becomes detached from the upper, at least one coil of ductile metal 31 interconnecting the two parts to limit the amount by which the lower part may drop and to absorb the shock. The lower part has the usual type of cable clamp 11 pivotally connected at 26 to a part 10 consisting of two opposed side members 21 each with two laterally extending arms 22. The upper part 12 has a foot extending into the lower part between the sides 21 and carrying two rollers 28 which engage under curved roller tracks 23 formed on the sides 21 and thereby support the lower part. A bolt 30 extends through the lower part and through a bight in the foot of the upper part, and a shear pin 29 extends through both parts, helical springs of annealed mild steel 31 connecting the two parts. If the cable on one side breaks, the clamp 14 swings, engages the end of an arm 22 and the resultant torque about the bolt 30 shears the pin 29 so that the rollers 28 run off the curved track 23 and the lower part separates from the upper. The springs 31 extend to limit the drop of the lower part and attached cable. In a modification the upper part is adapted for connection to two insulators (Figs. 4 to 8, not shown) which are suspended from the arm of a tower to form two sides of a vertically disposed triangle. The upper part is pivotally connected to the insulators by links in such a way that, when the device is tilted due to the cable breaking, the link connecting the insulator on the side furthest from the break is freed whilst the other insulator swings into line with the unbroken section of cable, the suspension device separating to absorb the shock as previously described. Specification 800,980 is referred to.

Title: Apparatus for measuring speed electrically
Inventor: ALDRIDGE-COX DOUGLAS
IPC: G01P3/48
Filed: 1959-04-28
Abstract: 875,900. Measuring speed. T.I. GROUP (SERVICES) Ltd. March 29, 1960 [April 28, 1959], No. 14409/59. Class 40 (1). [Also in Group XL (c)] Low speeds are measured with the aid of a switching device by means of which a capacitor is alternately discharged or charged rapidly and charged or discharged slowly, means being provided for measuring the voltage change during each slow charge or discharge period. As shown, a commutator 19 controls a bi-stable circuit 37. During the conductive period of the right-hand half, a capacitor 40 charges slowly with a substantially linear voltage change and during the non- conducting period a thyratron 42 fires and allows the capacitor to discharge rapidly. The voltage to which 40 rises in each cycle is thus inversely proportional to the speed of the commutator. This voltage is passed on via a cathode follower and a rectifier 48 with high back resistance to a capacitor 49 the voltage across which is passed on by a further cathodefollower to a voltmeter 54. Capacitor 49 holds its charge over several commutator operations and to avoid wrong reading during periods of rapid change it can be discharged manually at 52.

Title: Improvements in or relating to direction and movement signalling appliances for road vehicles
IPC: B60Q1/34
Filed: 1928-05-19
Abstract: 316,713. Oliver, J. W. H., and Bisby, J. H. May 19, 1928. Road-traffic signals on vehicles.-A signalling device of the stencil type is illuminated by daylight or artificial light reflectors from a mirror which can be rotated into and out of the operative position. Light passes through the upper face of the frame 10 and is reflected by a mirror 12 through a vertical face 13 to illuminate a stencil 14. The mirror is in three sections each adapted to illuminate one of the signs of the stencil and each capable of being rotated about the axis of the rod 17 so as to reflect light to or keep light from the stencil. For use at night a lamp holder 24 is mounted to slide in guides 25 so that it may either be situated above the upper open face of the frame or may be moved to the rear of the frame in order to allow daylight full access to the mirror. Electric lamps are carried by the holder 24 and can be lighted only when one of the mirror sections is in the operative portion to engage the contacts 30 and 31. In a modification, the stencil consists of a central sign " turn " with an arrow on either side and it is arranged so that the centre mirror section is brought into the operative position simultaneously with either of the side sections. The Provisional Specification describes a modification in which the signs are obscured or exposed by shutters.

Title: An improved method for increasing the Crystallization Rate of Crystallizable Polymers
Inventor: SAUNDERS FRANK LINWOOD
IPC: B29C48/09
Filed: 1967-03-31
Abstract: 1,189,141. Crystallizing polymers during moulding. DOW CHEMICAL CO. 31 March, 1967 [4 April, 1966], No. 14939/67. Heading B5A. During the formation of a rotationally symmetrical article from a crystallizable polymer, the rate of crystallization of the polymer is increased by subjecting it to shearing stress which is rotational, oscillatory or rotationaloscillatory while the polymer cools from its molten state to a temperature between its melting point and its glass transition temperature. The article may then be annealed at its melting point. The stress is preferably applied by relative rotation, oscillation or rotation with variable angular velocity which is always in the same sense, between two mould parts. When extrusion or compression moulding, the two parts are preferably the male die or core and the female die and when the article is an extruded tube the mandrel is rotated. The polymer may contain up to 15% of plasticizer. The preferred embodiment describes the preparations of polystyrene tumblers by injection moulding in a mould with a rotating core which is rotated with a predetermined torque so that it stalls when the polymer viscosity reaches a predetermined value. The tumbler formed has laminated walls with a central crystalline layer and has improved heat and solvent resistance.

Title: Data adapter
IPC: H04M11/06
Filed: 1974-04-05
Abstract: 1460354 Data transmission; interfacing adaptor INTERNATIONAL STANDARD ELECTRIC CORP (ITT Canada Ltd) 5 April 1974 15236/74 Heading H4K An interfacing adaptor, allowing a data processor to transmit via a private telephone line, has means for generating a local time base from received clock signals. Framing bits inserted into transmitted data are detected on reception, facilitating synchronizing with time base. A majority decision circuit verifies the parity of incoming data and signals are imposed on the line to disable it from speech signals during transmission. The apparatus may operate at a number of data rates and modes, which may be different from transmission and reception. The adaptor, Fig. 1, receives data on line 10 from a source, e.g. teleprinter, computer and is sent over leads 12 for transmission. When operative, a data tone is placed on the line as a warning against use for speech. Clock pulses from a local base at the subset feed a time base distributer 20 which generates multifrequency timing pulses selected through 22, 30 selected by latchable illuminatable push buttons on panel 42. Transmitted frames are defined by framing bits injected by circuit 24 which are detected on reception by 26. Prior to data interchange, control signals are exchanged with a remote station which signals indicate both Baud rate and format and which on reception cause an illuminatable buttons on control panel 42 (see Fig. 2, not shown) to "flash" thus indicating that they should be pressed to permit reception, when illumination ceases. Transmitted data is protected by redundancy and incoming data is sampled by a 4 out of 7 majority decision circuit. A circuit 36 produces various code words for signalling purposes described in greater detail with reference to Fig. 3 (not shown) and includes a modulo-32 counter to provide both 8 bits and 4 bit words which may be grouped into cycles. Selection of a remote station may be on a dialled basis by a telephone subset which plays no subsequent part in transmission. An inverted frame code may be transmitted to signify the setting up of a call.
