Title: Graft polymer production
IPC: C08F2/44
Filed: 1973-09-14
Abstract: 1408730 Graft polymerization on to carbonaceous materials LION YUSHI KK (LION OIL & FAT CO Ltd) 14 Sept 1973 [16 Sept 1972] 43246/73 Heading C3P So-called graft-polymers are produced by graft-polymerizing one or more vinyl or vinylidene monomers on to a carbonaceous material by bringing a carbonaceous material and one or more vinyl or vinylidene monomers dispersed in an aqueous medium into contact with sulphur dioxide. The carbonaceous material may be, for example, carbon black, coke, active carbon or graphite. Suitable monomers are vinyl halides, vinyl esters, unsaturated fatty acids and esters thereof, styrene and its substituted derivatives, a divinyl compound or a diene. The polymerization temperature is preferably from room temperature to 60 C. and the water may be mixed with an alcohol. The sulphur dioxide may be bubbled in as a gas, or produced in situ from a sulphite and an acid, or be used as an aqueous solution. Alternatively, SO 2  adsorbed on to a carbonaceous material may be added to an aqueous dispersion of the monomer(s). In the examples, monomers used are methyl methacrylate, vinyl acetate, styrene and methyl methacrylate, methyl acrylate, butadiene, and butadiene and styrene. Various types of carbon are used, including carbon fibres. The products are mouldable.

Filed: 1972-09-19
Abstract: 1406294 Pulse radar SIEMENS AG 19 Sept 1972 [29 Sept 1971] 43305/72 Heading H4D  A pulse radar system in which received echo signals are converted to a local function, stored and integrated over a number of repetition periods in a two-dimensional reversible multi-channel optical store has an optical analogue device for providing a Fourier transform of the stored signals. In a first system using a photo-chromic plate as the optical store, received signals are split into positive and negative portions via diodes (Fig. 3, not shown) and passed to light spot recorders where the squares of the signal amplitude is recorded on the photo-chromic plate by varying the optical transmission. The scanning is such that a number of parallel rows are formed each row representing a range cell, the whole pulse period being recorded on the plate. Subsequent periods are superimposed to integrate the received signal thereby eliminating noise. A lens 20 of focal length L is used to view the record and the frequency spectrum of the received signals is formed in the Fourier transform plane, at the positions of the diffraction patterns. The positive and negative halves are combined in parallel by the transform lens. In an alternative optical store, the recording is performed by an electron beam leaving a charge pattern on the surface of a KDP crystal which will rotate the plane of polarization of a linearly polarized coherent light beam. The beam is thereafter passed through an analyser which passes only the rotated pattern. The Fourier transform may be analysed by narrow photo-detectors.

Hop vines 7 are conveyed from a truck 2 to a stripping machine 11 by means of a conveyer system comprising a pair of parallel tracks 5 supporting carriers 4 which are clamped by hand on to vines 7 at a stop mechanism 19 and moved by hand or power to a switch 8 which automatically drives carriers alternately from the tracks 5 to a single inclined track 6 where each carrier 4 is engaged by a pusher 3 of a first conveyer chain 10 and driven nearly to 22 where the carrier 4 moves down an incline under gravity to a stop mechanism 9 where the pushers 3 of a second conveyer chain 18 release the carrier 4 and drive it through the stripping machine 11, between rails 12 to release the stripped vine and through a roller device 13 to remove the stripped vine (which is then chopped and conveyed to a truck), the carriers 4 then being switched alternately by a distributer switch 17 to the pair of tracks 5 where they move under gravity to the stop mechanism 19. Safety contactors 22, 23 prevent track crowding by switching off the drive of the chains 10 and 1, and of the chain 18 and the machine 11 when the tracks are full.  Stop mechanism 19.-A spring-loaded parallelogram linkage 24, 26 (Fig. 9) carries a stop cam 25, and two stop buffers 30 which engage a cam track 29 and which are pivoted at 39 such that when a carrier 4 abutting the cam 25 has been loaded, it is pushed by hand in the direction A past the cam 25 thus swinging the linkage and moving the buffers upwards clear of the next carrier 4 which moves into the loading position.  Switch 8.-Pushers 3 of conveyer chains 1 propel the carriers 4 through the switch 8 and are arranged to travel alternately through the switch 8 to avoid collisions between carriers. The switch 8 is switched by the carriers 4. Stop mechanism 9.-Each carrier 4 is halted by two pivoted spring-loaded two-armed levers mounted one on each side, or both on one side, of the carrier track. The pushers 3 of the chain 18 propel the carriers through the stop mechanism 9 against the spring-loading. Distributer switch 17.-Route-setting stops on the carriers 4 or on the chain 18 engage bars on the switch member to rotate it, one or more successive stops being directed first to one side and then the other.

Abstract: 1368983 Dispensing measured quantities of liquid LUBRASTART INTERNATIONAL 21 Sept 1971 43902/71 Heading B8N [Also in Division F1] Apparatus for dispensing measured quantities of a liquid e.g. a starting fluid for an I.C. engine, comprises a reservoir 22 containing fluid under pressure, a first valve 24 controlling passage of the fluid between the reservoir and a chamber 41 in which a spring biased piston 42 is slidably mounted, a second valve 50 controlling passage of the fluid between the chamber and an outlet, and means for actuating the valves such that either valve will be closed before the other is opened.  As illustrated the apparatus has its outlet connected by duct 12 to the intake manifold 13 of a vehicle I.C. engine, and the actuating means includes a solenoid 25 and a movable armature 26, the solenoid being in the vehicle starter circuit. Actuation of the starter switch (16) (Fig. 1, not shown), will cause downward movement of the armature 26. Valve member 51 is secured to the armature so that, upon downward movement of the latter, the valve 50 will open. During the downward movement of member 51, pin 53 will move similarly to permit movable member 95 to be biased by spring 97 towards its seat 96. The arrangement is such that the first valve 24 will close before the second valve 50 opens. When the solenoid is deenergized spring 27 will bias the armature to the Fig. 3 position thus first closing valve 50 and then opening valve 24 to permit a further volume of liquid to flow into the chamber 41 and displace the piston 42. The volume dispensed may be varied by using different length plugs 44, or by removing, at a groove 46, an axial length of the illustrated plug. An alternative form of reservoir includes an inlet 82 with a pin 85 secured therein, a screw closure 87 and a pressure gauge 90. Initially the reservoir is filled to the bottom of the inlet 82 and the closure with a gas container 88 positioned therein is then secured to the inlet. When the pin 85 pierces the container the gas therein will pressurize the liquid. The gauge indicates when refilling of the reservoir is required.
