IPC: C08F236/04
Filed: 1963-07-08
Abstract: Ethylene-butadiene copolymers having an X-ray diffraction spectrum with intensity peaks at 20=20.5 and 23.2 DEG  and an infra-red spectrum having absorption bands at 8.27, 9.25 and 11.2 microns, are made by contacting a mixture of the monomers, at a temperature lower than 0 DEG  C., with a catalyst comprising the reaction product of a hydrocarbon vanadium compound, an organometallic aluminium compound of the general formula AIR3 where R is a C 1 to 10 alkyl radical and a Lewis base. The catalyst is made at a temperature lower than 0 DEG C., e.g. - 50 DEG  to 100 DEG  C.  The polymerization is preferably effected in a hydrocarbon solvent.  The Lewis base may be diethyl, diisopropyl, diisobutyl, or diphenyl ether, anisole, diphenyl sulphide, thiophene, N,N-diethyl-aniline, or benzophenone.  The organo-aluminium compound may be aluminium triisobutyl. Preferably this compound is mixed with aluminium diisobutyl monochloride.  The exemplified vanadium compound is VCl4. The copolymer may be fractionated by solvent extraction.

[Class 97 (i).] A reflector for returning light along its direction of incidence comprises one or more units each consisting of a main element and at least two auxiliary elements of transparent material, each element being of right-angled triangular section and the elements being so arranged that the hypotenuses of the sections of the auxiliary elements are adjacent and parellel to the sides of the section of the main element which are at right angles to each other. Fig. 3 shows a unit consisting of the main element ABC and two auxiliary elements A<1> B<1> C<1>, A<11> B<11> C<11>. A ray i incident at right angles to the surface B C is successively reflected by the surfaces A B, A C, the emergent ray r being parallel to the incident ray. An oblique incident ray such as i<1> is returned parallel to itself after reflections at the surfaces A B, A<1> B<1>, A<1> C<1>, and A B, while a ray such as i<11> is returned parallel to itself after reflections at the surfaces A<11> B<11> and A<11> C<11>. The three elements are shown in contact, but in practice they are separated to enable the surfaces A B, A C to act as reflectors. Figs. 6, 7 and 8 show a reflector made up of a number of units as above described, the main elements being so arranged that the axes of any two adjacent elements are at right-angles to each other. These elements are all formed on a glass &c. plate P<1> and the auxiliary elements are all formed on a plate P<2> which fits over the plate P<1>, a packing member 1 being interposed to provide air spaces between the main and auxiliary elements. The plates are supported in a frame 2. The plates may be of circular or triangular form.

Abstract: 978,422. Aircraft ejection seats. MINISTER OF AVIATION. July 3, 1963 [July 18, 1962], No. 27577/62. Heading B7G. [Also in Division E2] An aircraft ejection seat comprises a clasp for clasping the head or helmet of an occupant to limit its motion relative to the seat, the clasp being rigidly and releasably secured to the seat. In Fig. 1, pulling of the seat ejection handle 25 results in each of two arms 14 (one shown) swinging forwardly so that a wire grid 22 thereon engages a rack 24 on the occupant's helmet 10. When the user wishes to separate from the seat, a member 49, on which the arms 14 are pivoted, is released from an attachment device 11 on the seat. Fig. 2 shows the apparatus ready for use, with the helmet 10 rested against member 49. A pull on cord 47 slides a bar 46 in guides 44 against spring 45, to remove a detent 41 from a notch (not shown) in rod 35, so that springs 29, 30 extend plungers 15, 16 through a fixed panel 34. These plungers swing arms 13, 14 about pivots 13a, 14a, to engage grids 22 in racks 23, 24, to hold the helmet. Cocking springs 54, 55 slip off hooks 52, 53 on the arms. Springs 17, 18 swing detents 19, 20 so that their ends 19b, 20b engage ratchet teeth 70, 71 on the arms to lock them (see also Fig. 1). Member 49 is normally attached to panel 34 by a boss 50 having slots 56, 57, Fig. 7, engaged by pivoted blades 58, 59 urged to the disengaged position by springs 60, 61, but restrained by a catch 62. On pulling cord 69, the catch is displaced and boss 50 is released, and is pulled through panel 34 by springs 29, 30 acting on arms 13, 14, and pushed by spring 39 acting on rod 35 and thus on boss 50.

Abstract: 831,617. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Aug. 8, 1958 [Sept. 3, 1957], No. 27711/57. Drawings to Specification. Class 40 (4). Outgoing and incoming relay sets employ voice frequency signals for setting-up, control, and supervision of connections over an interexchange link and add one pulse at the end of each voice frequency digital pulse train before transmission so that the first pulse of each train may be used to effect line-splitting at the incoming relay set. When taken into use the outgoing relay set transmits a voice-frequency pulse to seize the incoming relay set. Impulses are dialled into a mechanical impulse regenerator at the outgoing relay set, the registration in the regenerator being increased by one in response to the end of a digit. At the incoming relay set the first pulse of each digit train operates a line-splitting relay and the remaining pulses of each digit control routing. On reply, a voice frequency pulse constituting an answer signal is reverted to the outgoing relay set to complete the talking path. If the calling party clears first, a release guard lamp lights and a thermal relay is connected up to repeat a clear forward signal which causes the incoming relay set to revert a release guard signal until it has released following selectors. If the calling party clears before a digit is dialled a release alarm lamp lights as well as the release guard lamp and the impulse regenerator stores a single pulse but has its impulsing contacts masked so as not to interfere with the transmission of a clear forward signal. When the incoming relay set returns to normal the release guard signal ceases and the outgoing relay set is released. If the called party clears first a clear back signal is sent and the incoming relay set waits for a clear forward signal from the outgoing relay set before sending back the release guard signal. Where an operator controls the call from the outgoing end the called subscriber may flash his switch hook for attention and cause pulses to revert which are interpreted alternately as clear back and answer signals. It is stated that the inter-exchange link may be a radio channel.

Title: Reciprocating piston heat engines

Filed: 1975-09-15
Abstract: 1516982 Variable compression ratio engines R T JONES 15 Sept 1975 [22 June 1974] 27832/74 Heading F1B In a reciprocating piston combustion engine a junkhead 10 is provided which is driven via a rocker 15 or cam-shaft pivoted on an eccentric bearing 13 which is linked to an engine throttle valve actuating member so that the compression ratio is varied with throttle valve opening during engine operation. The compression ratio is arranged to increase as the throttle valve opening is reduced. In Fig. 1 (not shown), a two stroke engine has an inlet port (23) controlled by a disc valve (22). Combustible mixture is induced through the port (23) by the piston 24 and is compressed during the piston's working stroke. After opening of exhaust ports 25, junkhead 10 is raised by the cam 20 to open the transfer ports 19 to admit compressed combustible mixture to the cylinder. The ports 19 are closed again after a short time and the mixture is compressed in the cylinder and is ignited just after TDC. The junkhead 10 continues to move down the cylinder after ignition to keep the combustion volume constant until maximum pressure and temperature of the burning gases is reached. The junkhead then remains stationary until after BDC when the exhaust ports are about to be closed. The cam 20 then makes the junkhead rise rapidly so that the depression created in the cylinder helps the flow of mixture through the transfer ports 19. In Fig. 8 the invention is applied to a radial cylinder two stroke engine, and in Fig. 9 is shown a four stroke engine in which both the piston 24 and junkhead 10 are situated inside a rotating sleeve valve 36 which has a port 38 to control both inlet port 23 and exhaust port 25. Instead of the full length rotating sleeve, a sleeve just long enough to cover the junkhead may be provided, driven from the top of the cylinder.  The invention may be applied to side valve engines and to spark ignition or compression ignition engines.
