Title: Bonding cured olefin-polysulphides and related sulphur-containing plastics
IPC: C09J175/00
Filed: 1942-09-02
Abstract: Process for bonding cured olefin-polysulphides and related sulphur-containing plastics comprises applying to the surfaces to be bonded a cement comprising a low-boiling organic solvent, chlorinated natural rubber, and an isocyanate-modified polyester or polyester-amide, bringing the surfaces together and, if desired, submitting the joined treated surfaces to the action of heat.  The cement may contain formaldehyde or a formaldehyde-liberating substance, an aromatic compound carrying nuclear halogeno-methyl substituents, e.g. benzyl chloride, reinforcing agents such as carbon black and stabilizing agents such as ethanolamine, hydroquinone and oxalic acid.  A second coating of cement not containing chlorinated rubber may be applied over the first coating.  A suitable solvent is a mixture of trichlorethylene and acetone, and for the second coat, a mixture of benzene and acetone, benzene and ethanol or of trichlorethylene and methyl ethyl ketone.  The joined surfaces may be rolled with a heated roller until brought to a temperature of 120-150 DEG  C. Satisfactory bonds may, however, be obtained without heating especially when the cement contains compounds such as benzyl chloride.  The joined seams are particularly resistant to the action of petrol or oil, and structures made according to the invention may be used for flexible petrol containers for aircraft or for balloon construction.  Examples describe various cements for the binding together of sheets, or cured olefin polysulphide plastics, e.g. of cured Thiokol F and cured Novoplas A.  These cements embody isocyanate-modified polyester-amide manufactured as described in example 1 of Specification 580,524, together with chlorinated rubber known under the Registered Trade Mark "Alloprene B."

Title: Improvements in carrier telephone systems and the like
IPC: H04B1/50
Filed: 1944-06-30
Abstract: 586,165. Duplex wireless signalling; frequency modulation. GENERAL ELECTRIC CO.,-Ltd., and GLADWIN, A. S. June 30, 1944, No. 12479. Drawings to Specification. [Class 40 (v)] In a duplex system using frequency modulation, the undesired component of the receiver output, due to the use of the adjacent transmitted signal as the local oscillation, is substantially eliminated by the addition thereto of the input signal suitably changed in magnitude and phase, and with a suitable time delay. The transmitters operate on different carrier frequencies, the difference between them being .the intermediate frequency of the receivers. If the carrier frequencies are of nearly the same value, different aerials circuits or planes of polarization must be used by the transmitter and receiver at each station, otherwise a common aerial with suitable rejector circuits may be used. By careful design, the amount of adjacent transmitted energy picked up by the receiver may suffice for the frequency changing without further intercircuit connections. The aerial at each station may comprise an electromagnetic horn of such size and shape as to propagate freely both the transmitted and received waves, which have their polarizations at right angles. The horns communicate with the receiver' and transmitter through wave guides, a fraction of the transmitted energy being diverted to the receiver. When dipole aerials are used for transmission and reception with different polarization, the aerials at each station are set up at right angles to each other and at 45 degrees to the vertical.

Abstract: 1,098,877. Direction indicator switches for road vehicles. JOSEPH LUCAS (INDUSTRIES) Ltd. March 16, 1966 [March 26, 1965], No. 12876/65. Heading G4Q. A turn indicator switch comprises a rotatable actuating member 23 carrying bridging contacts 29 and 31 adapted to bridge fixed contact pairs on an insulating board 22. The member 23 is formed integrally with a pair of arms (of which one, 32b is shown in Fig. 2) each in corporating a latch portion 33b and a cam portion 34b. When the actuating member is rotated a latch portion rides up a corresponding ramp 20b until it engages a shoulder 51b of the ramp to latch the switch in the engaged position against the bias of a return spring. When the steering wheel is rotated to make the turn, a striker (49, Fig. 1, not shown) on the steering column engages the cam portion 34b and deflects the arm 32b towards the support 20; when the steering column rotates in the other direction after the turn, engagement of the striker with the cam portion 34b moves the arm 32b away from the support thereby releasing the latch and allowing the switch to return to its central position under the influence of the return spring. The latter may comprise a spring (53, Fig. 10, not shown) engaged by the opposite latch portion, or may comprise a V-shaped spring (26, Fig. 5, not shown) attached at its apex to the actuating member and having arms engaging lugs (27, 28) formed on the support 20.

Abstract: 470,295. Jib cranes. RANSOMES & RAPIER, Ltd., and STOKES, A. S. May 7, 1936, No. 12904. [Class 78 (iv)] The jib E of a crane is fitted with a pivoted head C which can be positioned by the link E to lie in alignment with the main portion of the jib or to be set an angle thereto. When the jib is in the full-line position below the horizontal, the pins E<1> on the end of the link engage recesses F<1> in fixed members in the frame. When the member G pivoted on the jib is in the position shown in the Figure, the raising of the jib causes the recesses G<1> therein to engage the pins E<1> and carry the link with them as the lifting proceeds, thus maintaining the member C at the same angle to the jib as it occupied in the lowest position. By using the handle H to swing the member G clockwise so that the recesses pass under the hooks F<1> before the jib is raised, the members E<1> remain in the recesses F<1> throughout the whole lift and the member C then occupies the position II instead of the position III at the end of the lift. The tail of the member G contacts with the jib pivot A<1> when the members G are supporting the link E. In a modified form the member C is provided with a series of holes any one of which can be brought into register with a hole on the main jib and fixed in a set angular position by a cross-pin.
