Abstract: 1,229,120. Releasable fastenings. UNITEDCARR Inc. 10 Sept., 1969 [20 Sept., 1968], No. 44659/69. Heading E2B. A device for securing an article or articles to an apertured support 18 comprises a resilient bush 2 insertable into the aperture and formed with means for retaining it in assembly and a flexible strap 3 having one end secured to the bush, a pawl 8 mounted within the bush, the strap being adapted to be looped around the article or articles to be secured and the free end portion of the strap threaded through the bush and secured by the pawl engaging one of a plurality of ratchet teeth 5 formed on the strap. In the construction shown the bush has a head 6 and the retaining means are spaced resilient legs 7 extending from the underside of the head, the legs having intermediate outwardly extending shoulders 12 engageable with a face of the support adjacent the aperture. The pawl depends from the head in the same direction as the legs and is disposed between the legs.

Abstract: 1,229,239. Safety harnesses. S. M. LINDBLAD. 24 Dec., 1968 [29 Dec., 1967], No. 61366/68. Heading A3V. A winding up mechanism for a vehicle safety belt comprises a roller 4, biased by a spring 10 in the winding-up direction, and an inertial locking mechanism in which upon sudden changes in the vehicle velocity, the ball 15 moves from a position of rest in the centre of a cup-shaped member 13 to co-operate with a locking member 11 that moves under gravity to lock the roller against rotation in the winding-off direction. In one embodiment, the locking member 11 pivotally journalled between flanges 3, has pawls 21 that can engage ratchet teeth 7 formed on flanges 6 of the roller 4. The cup-shaped member is carried by a rod 12 and has an opening 14 at the bottom into which a projection 11a of the locking member passes to be kept in position by the ball 15 when at rest thus maintaing the locking member 11 in an inoperative position. Sudden acceleration of the vehicle causing the ball to move from rest allows the projection 11a to swing up through the opening 14 whereupon the locking member 11 swings to its locking position in which it engages the matchet teeth 7. In a modification, Fig. 6 (not shown), a U-shaped locking member (16) has its centre part resting on the upper side of the ball at rest and drops to engage the ratchet teeth when the ball is displaced. In a further modification, Fig. 7 (not shown), movement of the ball from rest allows a leg (18a) of a lever to drop thereby pivoting a second leg (18b) to engage the ratchet teeth 7.

Abstract: 1,230,454. Toothed gearing. W. S. ROUVEROL. 14 May, 1968 [7 June, 1967], No. 22766/68. Heading F2Q. In a pair of mating gears having spiral or helical teeth formed at an angle such as to provide at least one overlap, the teeth have arcuate non-conjugate active profiles, the radii of curvature of the profiles having centres removed from the respective pitch surfaces and being of magnitude such as to give a relative radius of curvature greater than zero and less than the product of the pitch circle radii of the pair times the sine of the pressure angle divided by the sum of the pitch radii, thereby to confine tooth contact substantially to pitch point contact. The teeth of at least one of the gears are formed of mouldable material, preferably of dry bearing material.

[Also in Division B8] Apparatus for forming a continuous heat seal 20 between at least two overlapping portions 7, 8 of a travelling heat-sealable sheet wrapping material 1, e.g. heat-seal coated oriented polypropylene film, comprises a base-plate 9 over which the portions 7, 8 are drawn, an air chamber 12 having an outlet 13 facing the plate 9 for maintaining an air-cushion between the chamber 12 and the sheet material passing over the plate 9, means 16 for supplying air under pressure to the chamber 12 and a heater 18 to heat the air to a temperature above the heatsealing temperature of the sheet material, the gap 14 between the chamber 12 and the plate 9 through which air escapes from the air-cushion to the atmosphere being of such dimensions that it provides the principal restriction to flow of air in the path between the air supply means and the atmosphere. Preferably, the gap 14 is of a width between 0À0005 and 0À010 inch, e.g. 0À005 inch. As shown, the material 1 passes from a roll 2 around a former 6 which shapes it into a tube 1<SP>1</SP> with overlapping edge portions 7, 8. The plate 9 comprises a metal strip 10 suspended within the former 6 and covered with a silicone rubber sleeve 11. The chamber 12 has an open side 13 facing the plate 9 and is supplied with air from a compressor 16 through the heater 18. The chamber 12 and/or the plate 9 may be heated to reduce cooling in the sealing zone to a minimum. The sealed tube 1<SP>1</SP> is drawn downwardly by reciprocating jaws 21, 22 which transversely seal and cut the tube at bag-length intervals around goods 23. In modifications, Figs. 4-6 (not shown), the side of the air chamber which faces the plate 9 is closed except for a row of apertures or slots or a single slot in line with the direction of travel of the sheet material.

Abstract: 1295648 Gyromagnetic coupling devices VARIAN ASSOCIATES 24 Nov 1969 [22 Nov 1968] 57448/69 Heading H1W [Also in Division H3] A solid state microwave oscillator has a source 1 of microwave signals, an input coupling member 10 receiving the signals and a resonator 15 coupling the input coupling member to an output coupling member 11, which is orthogonal to the input coupling member, to produce an output signal in response to the microwave signals and to a magnetic field 17, Hdc such that the output frequency is a function of the intensity of the magnetic field. The resonator 15 is a ferrimagnetic resonator, such as a YIG sphere, and the source of microwave signals may be a bulk effect device, such as a Gunn diode 1. The input and output coupling loops 10, 11 and resonator 15 are mounted in a cavity 2 formed in copper blocks 4, 5. Alternatively the elements could be potted in epoxy resin. The earthed end of the input loop 10 is flared (Fig. 2, not shown). Spurious or parasitic resonances in the output signal can be avoided by interposing the YIG sphere 15 between the input and output loops (20, 21, Figs. 3 to 5, not shown), to reduce the coupling between them.

Abstract: 1295990 Non reusable launchers; projectiles NORRIS INDUSTRIES Inc 22 Dec 1970 [2 Jan 1970] 60955/70 Headings F3A and F3C A non-reusable hand-held projectile launcher comprises a forward tubular launcher section 23 having a rearward tubular case section 21 telescopically received therein so that the sections can be moved relatively to each other between a telescoped inoperative relationship to an extended operative relationship. A firing means including a trigger 34 is mounted on the launcher section 23 and is operable to fire the launcher only when the launcher is in its operative condition. The case section 21 has a nozzle fixed to its rear end (Figs. 5, 14, not shown) and houses a projectile 65 and a propellant charge 66, the projectile being retained within the section by a means which is releasable in response to gas pressure generated during the burning of the propellent charge. Obturator means 67, 75 are provided between the projectile 65 and the charge 66 to act as a piston in the launcher during the launching of the projectile. A seal 89, 90, 91 is also provided between the two sections of the launcher. In the construction shown the firing means also includes a spring-loaded, firing pin carrying sear 45, which is housed in a tubular member 38 fast with the case section 21, the sear 45 thus being cocked by engagement with the trigger 34 during the extension of the launcher. The trigger 34 is movable transversely of the launcher to release the sear 45, the firing pin 53 thereof being urged against a primer 50 which is positioned at the head of a firing line 48. The firing line 48 connects with an igniter mounted in a vented tubular member 69. The tubular member 69 is attached at its rear end to a plug seated in the nozzle (Figs. 5, 14, not shown) and is connected at its forward end through a shearable connection 73 with the obturator means 67, 65. The obturator means is releasably held in the rear end of the projectile and is released from the projectile by the camming action of pivoted fins 83 as they are erected under spring loading after the projectile has left the launcher. The rear end of the launcher is sealed against moisture by a plastics material. The plug in-the nozzle may be a solid body or a thin walled member consisting of two halves operatively connected together. The firing mechanism is provided with a safety (Figs. 7, 8, 9, not shown) which is slidable longitudinally of the launcher from an active position to a non-active position in which positions the safety is latched. A telescopic sight is pivotably mounted on the launcher section (Figs. 1, 2, not shown).
