Title: Sound-indicator for indicating hits scored on flying targets with weapons, especially aircraft weapons
IPC: F41J5/06
Filed: 1946-08-13
Abstract: 652,032. Target towing arrangements. SVENSKA AEROPLAN AKTIEBOLAGET. Aug. 13, 1946, No. 24027. Convention date, Aug. 13, 1945. [Class 4] [Also in Groups X and XXXVIII] Indicating - equipment associated with a flying target and adapted to indicate the result of firing during anti-aricraft practice comprises indicating means controlled by a sound-responsive device arranged in or upon the flying target or towed near it. In the embodiment shown a stream-lined container 1, Fig. 1, is towed behind an aeroplane and in turn tows a sleeve or other target. When a shot passes near the target it produces a pressurewave which enters slots 12 and impinges on a corrugated diaphragm 11. The air in a funnelshaped chamber 2 is therefore compressed and lifts a spring-loaded valve 5 from an electrical contact 7. In the towing aircraft is located a thyratron 18, Fig. 4, whose negative grid-bias is supplied over a conductor 22 in the tow-rope, contact 7, valve 5, and return conductor 23 in the tow-rope. When, therefore, the valve 5 lifts in response to a nearby shot, the negative bias is removed from the thyratron 18 which fires, energizing an anode relay 26a. A lamp 28 is lighted and a counting device 29 operated over contacts 26c and a sluggish relay 27a is energized over 26b. When relay 27a operates contacts 27b quench the thyratron 18 and release relay 26a. The lamp 28 remains energized at 27c, until, as a result of contacts 26b now being open, sluggish relay 27a releases and the circuit is restored to normal. The lamp 28 may be mounted on the container 1 or on the target, and lighted by means of further conductors in the tow-rope. The impulse received from a shot may be utilized to send out a radio signal or a smoke signal. The zone in which a shot is effective to raise the valve 5 may be altered by adjusting its spring loading, the rigidity of membrane 11 or the size of the slots 12.

A parachute pack comprises a base and closure flaps forming a container for a parachute and its rigging, wherein a principal flap extending from one side of the pack is detachably secured to the remote side of the pack by quickly releasable means disposed inside the pack but operable from outside, so that on release and swinging of the flap in an opening direction, substantially the whole of the face of the pack is opened. The pack comprises a base 1 to which are attached end flaps 2, 3, and a principal flap 4, extending from one side of the base to the other. The flap is releasable by cone and grommet fastenings, the cones 10 on the flap extending inwardly through grommets on the side of the pack and being secured by rip pins. A sliding plate 30, Fig. 3, covers these fastenings. The other side of the flap is secured to the pack by a zip fastener 33 so that the parachute may be packed while the cone and grommets are secured together, the zip fastener then fastening the flap 4 down. Alternatively, cone and grommet fastenings may be used at each side of the flap, when the latter is centrally divided into two portions connectable by a zip fastener for packing, Fig. 13 (not shown). A pocket 28 on the base contains a barometrically or time-delay operated rip cord actuator. One cable thereof is operable by the wearer to arm the actuator, and another to provide an overriding manual release; Figs. 10-12 (not shown).

Title: Apparatus and process for blow molding hollow articles
IPC: B29C49/28
Filed: 1962-06-27
Abstract: 966,276. Blow-moulding thermoplastics. QUESTRON INDUSTRIES Ltd. June 27, 1962 [June 8, 1962], No. 24700/62. Heading B5A. Hollow articles are made by feeding a continuous tube of warm plastic material downwards, severing lengths from the tube so as to leave the upper end of the length open, moving the length, transversely of the direction of feed, to a mould, enclosing the length in the mould and forcing air through the upper end of the length to expand it to the mould walls. Fig. 2 shows an extrusion nozzle 2, directed downwards, on which is mounted a pneumatically controlled cutting assembly 3 (details, Figs. 3, 4, 5, not shown). When an extruded tube, or parison, breaks the beam of an electric eye 10, fingers 30 of a gripping assembly (Fig. 9) close to grip the parison and in closing, close a microswitch B which actuates the cutting assembly 3, and actuates a cylinder 34 to move carriages 25 carrying the severed parison along tracks 23 to a position between mould halves 36 (Fig. 2). A blow pin 42 is lowered and inserted into the parison, cylinders 40 cause the mould halves to close (Fig. 11, not shown), the gripping fingers are released and withdrawn, and fluid is supplied to blow pin 42 so that an article is blowmoulded. After a period controlled by timers the mould is opened and the article stripped from the blow pin as the pin retracts through a bearing 44 (Fig. 15). The various steps outlined above may each be initiated by microswitches actuated by completion of the previous step, microswitches controlling pneumatic valves (Figs. 16, 17, not shown), or the microswitches may be actuated by a series of cams on a single driving shaft (Fig. 18, not shown). A second embodiment, Fig. 21, comprises two pairs of mould halves, mounted on plates 83, moved by cylinders 86. A gripping assembly (Fig. 22) comprises two sets of gripping fingers 92, closable by cylinders 95, and mounted on each end of two cylinders 99, which slide along piston rods 100. Alternate lengths of parison extruded from an extruder 62 break the beam of an electric eye 81 causing left-hand fingers 92 to grip them, a knife (not shown) to cut them off and a bumper assembly 82 to close their lower ends. Cylinders 99 then move leftwards and the parison is blow-moulded in the lefthand mould as above, while a second parison is being extruded between right-hand fingers 92, now under the extruder 62. Control systems as above may be incorporated. Figs. 33, 34 (not shown) illustrate an alternative cutting assembly, in which a metal knife is heated by passage of electricity, in either of its two " rest positions," but breaks contact while moving across to sever a plastic tube projecting through its frame. Mould halves may be timed to open slightly before the pressure within the article is released. Polyethylene, polystyrene, polypropylene, polyvinyl chloride, polyvinyl acetate, copolymers of vinyl chloride and vinyl acetate &c. may be moulded in this manner.
