Abstract: 969,640. Selecting portions of cinematograph films. GEMCO (ELECTRONICS) Ltd. Dec. 20, 1962 [Sept. 25,1961], No. 30808/61. Heading G2E. [Also in Division G5] A sound-film projector which may be coin operated is provided with selection means so that portions of a film strip can be shown as required. In the embodiment shown in Fig. 2 a cinematographic projector 2 has a reel 3 from which a film 4 passes via rollers 11 and 12 and picture gate 16 to a take up reel 5. For fast winding and rewinding of the film on to reel 3, rollers 11 and 12 may be withdrawn to positions 11a and 12a on energization of solenoid 19 to disengage the film from the picture gate. The diameter of the film on reel 3 is sensed by a rotatable wheel 25 attached to a bifurcate portion 24a of arm 21 pivotally mounted on base 23 at 22. The bifurcate portion 24b of arm 21 has an electrical switch wiper 27 on its free end, the wiper being slidable in groove 28 of base 23. Nine pairs of electrical contacts P1-P9 are positioned along the sides of groove 28 so that they are bridged in turn by wiper 27 as film is unwound from reel 3. An electrical circuit is provided (Fig. 4, not shown) so that on the suitable setting of a dial switch and the insertion of a coin into the machine one of eight portions of film is shown. The film is first unwound at high speed from reel 3 until wiper 27 reaches the pair of contacts corresponding to the beginning of the selected film sequence. The high speed motor driving the film is then stopped and its field winding connection automatically reversed. After a delay to allow the stoppage of reel 3 and the film to be engaged in gate 16, a low speed motor is started to drive the film through the gate at projection speed. As the selected film sequence nears its end the wiper 27 approaches the next pair of contacts and on bridging them causes the low speed motor to cease and the film disconnected from gate 16. After a suitable delay the high speed motor is energized to rewind the film on to reel 3. When wiper 27 reaches the outermost contacts the high speed motor is de-energized and its field winding connections reversed so that the machine is made ready for the next coin insertion. Multiple projectors, showing the same sequence simultaneously, or showing a wider selection of sequences at the same or independent viewing points may be provided in the one cabinet.

Abstract: 846,381. Electric selective signalling systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Oct. 25, 1956 [Nov. 4, 1955], No. 31535/55. Class 40 (1). - As described, the digits of a 5-digit decimal number are received successively at terminals A1-A4, highest denomination first in binarycoded decimal form (e.g. from a punched-tape reader) are staticized on relays-one digit in each of five " relay operating units "-are each used to select one of ten tappings of a transformer to produce A.C. potentials having amplitudes representative of the five digits at terminals U, T, H, Th and Tt, which potentials are both scaled by factors 10<SP>-4</SP>, 10<SP>-3</SP>, 10<SP>-2</SP>, 10<SP>-1</SP> and 1 respectively and summed by means of series connected 1-10 transformers TR2, TR3, to produce, from the secondary winding of transformer TR2 a single final output potential on a terminal A5 representative of the staticized decimal number. Each " relay operating unit "-one only being shown in detail-comprises four relays and is so arranged that on the application of a negative pulse to its normally positive control terminal A6-A10 its four relays assume conditions corresponding to the potentials then present on terminals A1-A4. These conditions are maintained by the relays until changed by a further negative control pulse. Thus to staticize the incoming decimal digits, the terminals A6-A10 are pulsed negatively in succession in synchronism with the receipt of successive digits. The output of the converter may be used in a servosystem, as a command, to position, for example, a machine tool, the command being applied to a differential amplifier SA together with a signal, such as obtained by a brush W moving over contacts SW, representative of the position of the machine tool. Specifications 726,037, 796,993 and 802,472 are referred to.

Title: Interpolymers
IPC: C08F210/00
Filed: 1966-07-15
Abstract: An interpolymer of at least one monoolefine and a multi-unsaturated hydrocarbon, which is soluble in hydrocarbon solvents and contains sufficient ethylenically unsaturated groups to permit substantial curing of thin films of the interpolymer by an oxidative mechanism is made by interpolymerizing a mixture of the monomers in a liquid reaction medium containing a Ziegler-Natta-type catalyst and 4-vinylcyclohexene-1. The Specification contains an extensive list of suitable monomers. Exemplified monomeric mixes are ethylene and dicyclopentadiene, and ethylene, propylene and dicyclopentadiene. Other molecular weight regulators such as hydrogen and a dialkyl zinc may be used along with 4-vinyl-cyclohexene-1. Exemplified catalyst systems are of ethyl aluminum sesquichloride and vanadium tris(acetylacetonate).  The interpolymers may be cured by auto-oxidation but generally the curing is assisted by drier such as metal naphthenate, octoates, or linoleates.ALSO:Substrates are coated with a composition comprising a hydrocarbon-soluble interpolymer of at least one monoolefine and a multiunsaturated hydrocarbon, which is curable in thin films by an oxidative mechanism, and which has been prepared by interpolymerizing a mixture of the monomers in a liquid reaction containing a Ziegher-Natta-type catalyst and 4-vinylcyclohexane-1.  The composition can contain conventional pigments and additives.  It may be a hydrocarbon solvent solution, a water-in-oil or oil-in-water emulsion, or a plastisol, or an organosol.  The compositions may be cured at ambient or elevated temperature in the presence of oxygen but preferably conventional metal driers are present.  The substrate may be of iron, steel, aluminium, copper, nickel, tin, wood, glass, or a polyester.  In Example VI an interpolymer of ethylene, propylene, and dicyclopentadiene, was coated and cured on phosphatized steel panels.
