Title: Improvements relating to strap assemblies
Inventor: HARLEY FRANK BERNARD
IPC: B60R22/30
Filed: 1967-12-19
Abstract: 1,255,929. Safety harness. HARLEY PATENTS (INTERNATIONAL) Ltd. and F. B. HARLEY. 16 Dec., 1968 [19 Dec., 1967], No. 57580/67. Heading A3V. In a connector assembly, e.g. for safety harness in ejector seats, hooks 10, 11 are interconnected by a strap 45 secured at one end by a loop 40 to a bar 19 of a buckle 17 and which passes through slots in the hooks 11, 10 respectively, and then under and round a toothed roller 20 at the other end of the buckle, whereby when the free end 47 of the strap is pulled, the hooks 10, 11 are pulled towards one another. The slots in the hooks have U-shaped slipping plates around which passes the strap, and the buckle has, in addition, a spring biased movable anchorage (25), Fig. 1 (not shown), the arrangement being such as to allow tightening but prevent slackening of the strap as described in Specification 922,070. A webbing loop 32 is attached to the movable anchorage which, when pulled to the right, permits the strap to be released. The strap runs 34, 35, 36 are stitched together. (For Figure see next page)

Abstract: 1,221,477. Monitoring respiratory apparatus. AIR REDUCTION CO. Inc. 6 Dec., 1968 [6 Dec., 1967], No. 58064/68. Heading A5T. [Also in Divisions G1 and G3] In an apparatus for monitoring the ultra violet absorption of a sample of respiratory gas, the sample is encompassed within a rotating drum having two diametrically opposite openings one of which contains a pane of fluorescent material, and the openings are aligned twice during each drum revolution with a source of ultra violet light, means being provided for reading the difference in light intensity passing through the sample and the two apertures when respective ones of the two apertures are adjacent the source. The apparatus is used for monitoring and/or controlling the amount of anaesthetic in a rebreathing system, the sample being held within a fixed container within the drum or in the drum itself. The sample is withdrawn by a pump, and the amount of anaesthetic is controlled by passing withdrawn gas through a vaporizer including a liquid halothane reservoir, the circuit including a pump, and solenoid valves controlled by a photocell responsive to the light passing through the drum apertures. The signals from photocell 32, Fig. 2, are gated to measurement and reference stores 38, 39, by reed switches 36 actuated by a magnet attached to the periphery of the drum, and the indication and control are made by meter 44, and meter relay 45 respectively. Source 31 is regulated by the detected reference signal and extreme conditions are arranged to operate appropriate alarms. The vapour concentration may be preset by a controller 46 and false alarm operation during a warming up period is prevented by a relay 61. An excess of halothane is also arranged to operate an alarm and in the event of alarm conditions the vapour control loop may be shut down.

The tray may be lined with polyethylene and the lid with polyvinyl acetate, this combination gives a suitable seal that fails at the required temperature and pressure. The lid may be secured by an aqueous acrylic emulsion which is a pressure sensitive adhesive. The blank shown is erected to form a tray with a central partition 84 but this partition can be omitted. Corner portions 15a are connected to wall 14a by a fold line 53a and are separated by a cut 54a from adjacent wall 16a, the cut does not extend to fold line 26a so that a land is formed when the walls are erected. The portions 15a are folded on to the outside of adjacent walls and sealed thereto. If only one side of the blank has been coated with the thermoplastic material an adhesive is used to secure the portions 15a. The tray walls diverge upwardly at about 17 degrees to facilitate nesting of empty trays.

Title: Cylinder lock
IPC: E05B27/08
Filed: 1973-12-28
Abstract: 1460156 Locks R FRANK 28 Dec 1973 [29 Dec 1972] 60109/73 Heading E2A In an axial-tumbler type barrel lock, the rotatable barrel 2 is circumferentially slotted at 17 to receive a split ring 6a, 6b which is externally lobed at 19 to enable it to slide into and out of the bore of casing 1 during assembly &c, but which has inner channels 18 which accommodate the tumblers 4 carried by the barrel, but which only allow rotation of the barrel when these tumblers are axially moved to positions at which they present notches 18 to the split ring. The tumblers have false notches 20 to frustrate picking. The barrel is retained by a projecting pin 25 whose head rides round in retaining slot 28 in the housing until it registers with axial entry/ withdrawal slot in the housing. Normally, it is prevented from being withdrawn even in this position by a plunger 31 whose tail 36 engages another circumferential slot 36 in the housing. When the key is inserted, the nose 32 of this plunger engages a notch 40 under pressure from circumferential spring 35 to retain the key unless the barrel is in its zero position at which the plunger tail is opposite a hole 37 in the casing to allow its radial movement. To remove the barrel, e.g. for changing the tumbler setting, a special key having a notch 40 deep enough to allow the plunger tail to clear the groove 36, is used. The barrel 2 drives a bolt actuator 22 through a short splined shaft 14, the actuator being indexed by catch 53. A modification is described (Figs. 6 and 8, not shown) in which two such locks are placed back to back (for opposite sides of a door) and insertion of the key in one end or the other of this composite lock, besides moving the tumblers to their releasing position, also pushes the splined shaft 14 of the operative lock into, and the other out of, the correspondingly splined hole 62 in the web 61 of the bolt actuator. The tumblers may have additional notches for master key operation.

Abstract: 743,678. Dry plate rectifier assembly. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., PETER, L. H., and SHEPPARD, E. A. March 3, 1954 [April 22, 1953], No. 11062/53. Class 37. A rectifier assembly comprises a hollow cylindrical body of insulating material with a number of slots in its peripheral wall to locate connector springs, each formed with a pair of resilient inwardly projecting arms, and containing rectifier elements, e.g. copper oxide or selenium, each gripped between the adjacent arms of two adjacent springs. In the embodiment springs 4 are located between the cylinders 1 and 2 with resilient arms 3, 7 projecting through slits 13 in the latter. The rectifier discs 8 are clamped in radial planes between arms 3 and 7 of adjacent springs each formed with a projection 6 bent to project radially inwards through gaps 14 in wall 2. The open end of the composite cylindrical body, which may be filled with resin sold under the Registered Trade Mark " Epikote " is closed by insulating plate 12 formed with an internally threaded central boss 11. External connectors 5 soldered to projections 6 pass through the cover, or the projections are extended in an axial direction through peripheral slots in cover plate 12 or through slots in the base 15. In another arrangement the cover plate is formed integral with the outer cylinder and the projections are extended through slits in either or both bases. When a resin filling is used the cover may be dispensed with and the inner and outer cylinders formed integral with a common base. The spring arms may be so formed as to hold the rectifier discs with their axes radial.
