Title: Improvements in or relating to a method and an apparatus for forming shaped cellulararticles from expandable thermoplastic resins
IPC: B29C44/34
Filed: 1965-08-23
Abstract: A shaped cellular thermoplastic article is formed by feeding granules of an expandable thermoplastic material into a mould chamber which defines the shape of the article at a temperature below the softening point of the thermoplastic material, heating the granules to 5-10 DEG F. above the softening point of the thermoplastic material by means of high-frequency electrical energy, allowing the heated particles to expand and fuse together under a vacuum of from 15 to 30 inches of mercury and, thereafter, removing the shaped article from the mould. If desired the expanded contents of the mould may be allowed to cool under vacuum and then cooled completely with air under pressure before discharging the mould.  Preferred expandable thermoplastic materials, with high power-loss factor, are homo-polymers of styrene containing up to 10% of wood flour or walnut shell flour or copolymers of styrene with, for example, tri-methylol-propane monoallyl ether.  Polystyrene, polyethylene, polypropylene, poly(alkyl - substituted - styrene), polyacrylic esters, polymethacrylic esters and copolymers of styrene with a -methyl-styrene or alkyl - substituted - styrene may be used in conjunction with a coating of a high power-loss factor material.

Title: Fet delay circuits
IPC: H03K5/133
Filed: 1976-09-02
Abstract: 1523080 Binary delay circuit INTERNATIONAL BUSINESS MACHINES CORP 2 Sept 1976 [28 Nov 1975] 36284/76 Heading H3T An FET circuit to produce a delayed output of a binary input signal comprises an input switching stage 1 to which an input V, to be delayed is applied and whose output provides a signal V 1  delayed by a predetermined time, a capacitance Cl which is charged to a predetermined voltage, e.g. via T2, and discharged following application of the input to the input stage. The delay circuit further comprises a capacitive coupling circuit C2 to apply the input signal to the capacitance C1 and a discharge circuit Tl which at least partially discharges the capacitance. An output driver stage 2 may be used, it is said to be known from 1,385,149 and is an improved boot strap driver using two inverters T 11, T12 and T13, T14 in parallel with a bootstrap capacitor C3 charged via an insulation stage 3 and T30 within this stage. The input stage 1 has C1 charge, by T2 being turned on via V p , substantially to the supply V H . A subsequent edge applied to the input passes directly through capacitance C2 to give an increased voltage on C1 and T1 subsequently discharges C 1 in a linear manner due to feedback through the inherent source-gate capacitance. Eventually the voltage is such that the output stage changes state. Resetting the circuit to the initial stage involves the discharge of the capacitance at the gate of T1 by T4. The optimum width/length ratios are given for the various transistors. Many minor changes in the means for pre-charging of C1 and resetting the gate capacitance are given (Fig. 5, not shown).

Title: Latching device
IPC: E05C19/02
Filed: 1946-12-10
Abstract: 619,442. Automatic catches. PHILLIPS SCREW CO. Dec. 10, 1946, No. 36469. Convention date, Aug. 12. [Class 44] A catch for two relatively movable members, e.g. the door and frame of a cabinet, one of which. is biased to move relatively to the other, e.g. by a spring, in the opening direction, comprises a latch fixed to one member, and a keeper pivotally mounted on the other member and having its free end normally projecting into the path of the latch, the keeper having a shoulder facing away from the pivot, which shoulder engages and restrains the latch in latched position after it has been moved in closing direction and then returned slightly in opening direction by the biasing means. The device is arranged so that it may be wholly concealed when mounted on a cabinet. The latch, shown as mounted on the door, comprises a flanged plate 30, Fig. 3, having a projecting part 33 with two turned-up lugs 34, 35. The keeper, mounted inside one side of the cabinet, has a base plate 16, Figs. 2 and 6, to which is pivoted a keeper member 17 comprising a pear-shaped base with an outstanding boss 21 defining a shoulder 22 with depending lips 23, and an upstanding stop 24. In movement of the door to closed position, the lug 34 first abuts against the side of the boss 21 of the keeper, swinging the latter to the position of Fig. 9, when the flange 31 of the plate 30 of the latch abuts against the upper'part of the keeper, the door being then past its normal closed position. The door, biased by a spring device, say near the hinges, rebounds, allowing the keeper to drop to the position of Fig. 11, in which it is arrested by abutment of the latch with the under side of shoulder 22. To open, the door is pushed inwardly to the position of Fig. 13, freeing the latch from the keeper, and is then allowed to swing open under the influence of the biasing spring ; during opening, the latch merely swings the keeper aside without engaging between shoulder 22 and stop 24. The lug 35 is arranged to prevent the keeper from swinging up over its pivot if the door is slammed. In a modification, the keeper is biased to its centre position by a spring.

Abstract: 753,838. Ammunition projectiles. SOC. NOUVELLE DES ETABLISSEMENTS BRANDT. Dec. 17, 1954 [Dec. 21. 1953], No. 36555/54. Class 9(1) A rocket 1 is provided with a collapsible fin structure comprising a support S and three fins A pivoted on pins 13 mounted longitudinally of the support, the fins being so shaped that in the collapsed position the outer form of the structure is a right-circular cylinder. At the forward end, the support is screw-threaded for attachment to the rocket body. An axial passageway 4 through the support acts as a jet nozzle for the propellant gases and is fitted at the rear with a ring 6, Fig. 5, provided with internal fins 7 inclined to the axis of the projectile to deflect the gases and hence rotate the projectile. The support has a stepped portion 8 merging into a cylindrical portion 9 from which the support flares rearwardly to a flange 11 containing the ring 6 and provided with bosses 12 to receive the pivot pins 13 which extend through lugs 14 from blind holes 15 in the part 8. The fins which are of metal or light alloy such as "Duralumin" (Registered Trade Mark), consist of two parts 16, 17 with an intervening rib 18, the outer curvature of the part 16 being equal to the inner curvature of the part 17, so that in the closed position the part 17 of each fin fits over the part 16 of an adjacent fin, the diameter of the structure then being that of the body of the projectile. A strap 33 holding the fins in the collapsed position is stripped off as the projectile is launched, the fins being held during launching by the launching tube. As the projectile leaves the tube, springs 29 force the fins outwards. The fins then set back on their pivots until a notch 22 in each fin engages a projection 23 from each boss 12 to lock the fins in the extended position. Each part 16 tof the fins has reinforcing ribs 21 and each part 17 has two apertures 28 to receive the pivot eyes 19, 20 when the fins are folded.
