Abstract: 1,199,314. Tracked air cushion vehicles. BERTIN ET COMPAGNIE. 14 Sept., 1967 [14 Sept., 1966], No. 41911/67. Heading B7K. An air cushion vehicle 16 operating over a fixed inverted T track 17, is formed with two plenum chambers 19 within which supporting air cushions 18 are formed by air delivered by fans 24 which draw air through ducts arranged on both sides of the upright rail of the track and are connected to an air intake 22. By this means the vehicle is supported by pressure cushions and guided laterally by low-pressure cushions. The reduced pressure in the guiding cushions may be adjusted by a roller which senses lateral movement of the vehicle with respect' to the track to control the speed of the respective fan 24 (Fig. 2, not shown) or the faces of the vehicle opposite the vertical faces of the upright track rail are convex so that with lateral movement of the vehicle the effective pressure in the guiding cushions is increased (Fig. 3, not shown).

Title: Improvements in or relating to the production of polyvinyl acetate
Inventor: CLARKE DDNNIS
IPC: C08F18/08
Filed: 1963-10-30
Abstract: A process for producing polyvinyl acetate comprises polymerizing vinyl acetate in aqueous suspension at an elevated temperature in the presence of a polymerization initiator, a volatile chain transfer agent and a dispersing agent, removing volatile contaminants by agitation of the polymer suspension with intermittent vacuum application, and recovering the suspended polymer.  The vinyl acetate may be copolymerized with internal plasticizer monomers, e.g. alkyl acrylates and dialkyl maleates. The preferred chain transfer agent is acetaldehyde. The initiator may be benzoyl or lauroyl peroxide.  The dispersing agent may be ionic or non-ionic.  The polymers may be used as chewing gum bases.  In an example vinyl acetate is polymerized by adding a mixture thereof with benzoyl peroxide to a heated aqueous medium comprising acetaldehyde, sodium polyacrylate and oxyethylated stearic acid.

A continuous rod of tobacco is formed from two streams, one of which is formed by a joint grooved suction wheel, and the second of which is formed on a second grooved suction wheel of smaller diameter fed with the tobacco trimmed from the first suction wheel. As shown the tobacco is fed from a U-folded belt 3 on to and at a slightly lower speed than the peripheral speed of a suction wheel 8 rotating anticlockwise. It is first blown up against a flexible elastic plate 123 extending from a guide-plate 23 by a draught of air flowing through a gap 9. The flexible plate 123 has a fork-shaped end and the guide-plate 23 is pivortallymounted by a pin 24. A trimming wheel 29 is provided for transferring excess tobacco from the first wheel 8 to a second suction wheel 8<SP>1</SP>. The trimmed tobacco filler stream is released from the suction-wheel 8, when it reaches the lowermost point of rotation, by a fixed packing 113 which cuts off the suction. The filler stream is then directed on to a conveyer band 5. Any remaining tobacco particles are removed from the wheel 8 by air forced into a space 42 in the packing 113 and discharged through a tube 45. The excess tobacco trimmed by wheel 29 and fed to the second suction wheel 8<SP>1</SP> is also formed into a filler and directed on to the conveyer band 5. The wheel 8<SP>1</SP> is similar to wheel 8 but smaller, like parts being referred to by the same reference numerals with primes added.

Abstract: 1,046,255. Magnetic storage devices. RAYTHEON CO. Nov. 5, 1963 [Nov. 23, 1962], No.43689/63. Heading H3B. A magnetic memory includes a plurality of magnetic units arranged in an array each unit comprising a block of magnetic material having non-intersecting orthogonally disposed interrogate and storage holes. The basic memory unit is as shown in Fig. 1 (not shown) with an interrogate winding 15 threading the lower interrogate hole and a word write conductor 14 and a bit write conductor 13 threading the upper storage hole, the latter conductor also acting as a sense winding. In operation the direction of the magnetic flux around the storage hole is indicative of the information stored and in order to write a " 1 " into the core current pulses of opposite polarity are applied to conductors 13, 14 and to write a " 0 " current pulses of the same polarity are applied to these two conductors. Read-out is achieved by applying a current pulse to interrogate conductor 15 so as to create a temporary change in the flux in the region between the two holes shared by the two flux paths and thus inducing a bipolar output signal in the sense winding 13. A " 1 " is indicated by a positive pulse followed by a negative pulse and a " 0 " by a negative pulse followed by a positive pulse, Fig. 5 (not shown), and are detected in strobed sensing unit 17. In accordance with the invention the memory units are arranged in an array, Fig. 2, with the storage and interrogate holes of the units aligned with each other as shown. Each plane is wired as shown in Fig. 3 with the bit write and sense conductor 13 being threaded through the aligned storage holes. Similarly the interrogate conductors 15 are threaded through the aligned interrogate holes of rows 35 and returned on the outside of the elements. The interrogate conductors are perpendicular to the sense windings so as to minimise the electrostatic and eliminate electromagnetic coupling. The word write conductors 14 are threaded through aligned storage holes in serpentine fashion. Fig. 4 (not shown) indicates how the sense windings may be arranged between rows to minimise the effects of stray fields. Reference has been directed by the Comptroller to Specification 927,905.

Title: Improvements in Semiconductor Rectifier With Improved Turn-On and Turn-Off Characteristics

Abstract: 1,161,500. S.C.R. GENERAL ELECTRIC CO. 30 Sept., 1966 [22 Oct., 1965], No. 43780/66. Addition to 1,112,301. Heading H1K. The S.C.R. of the main patent, in which an auxiliary region of the same type as the emitter is located between the emitter and the gate contact, is improved by increasing the area of the auxiliary region. As shown, Fig. 1, the cathode region 41 of an S.C.R. comprises a main area A which is contacted by the cathode electrode 45, an area B which has a relatively high lateral resistivity and an area B<SP>1</SP> which has a relatively low lateral resistivity due to an island 70 of conductive material on its surface, the gate contact 47 being applied to base region 42 adjacent to the area B<SP>1</SP>. When a trigger signal is applied to the gate contact a potential drop is produced in region 41 but since region B<SP>1</SP> is effectively shorted by island 70 the current flow is spread along the length of the gap between the cathode 45 and the island 70, Fig. 2 (not shown), thus preventing hot-spot formation. The current path is then transferred to region 42 as described in the main Specification. The island 70 may be produced by etching a slot 71 in the metallic electrode and may be covered with a layer of a room temperature curing rubber (not shown). In a modification, Fig. 3 (not shown), the conductive island comprises an annular region (80a) surrounding the cathode electrode. It is stated that the gate conductor may be connected to the metallic island. In a second embodiment, Figs. 4 and 5 (not shown), the gate electrode is located in an aperture in the cathode electrode and the cathode region has an uncontacted portion situated between the contacted cathode region and the gate electrode. A conductive island may be provided round the inner edge of the uncontacted cathode region and may be in the form of a disc which is used as the gate electrode. The device also exhibits improved characteristics when operated in the avalanche mode (i.e. when the device is fired by increasing the anode-cathode voltage to the breakover value).
