Abstract: 784,182. Door latches. CHICAGO FORGING & MANUFACTURING CO. Aug. 22, 1955, No. 24183/55. Class 44 A hood latch assembly for motor vehicles and the like of the kind which comprises an apertured latch plate 10 arranged to receive a keeper 21 and a latch bolt 60 pivotally mounted on the plate so as to engage the keeper and hold the latter in its latched position has an operating lever 80 pivotally mounted at or near one of its ends to the latch plate and provided with an abutment 82 adjacent this end for the purpose of actuating the latch bolt upon movement of the lever towards the unlatched position, the end of the lever remote from its pivotal mounting having an integrally formed safety hook 100. The keeper 21 has a stem 25 and a conical enlargement 26 underneath which a tongue 70 on the latch bolt 60 engages. The keeper passes through a guide 31 which is made in the form of a cup and which is attached to the latch plate 10. The latch bolt 60 is generally U-shaped and is pivotally supported on the latch plate 10 by loose rivets, one of the rivets also supporting the operating lever 80. The latch bolt is leaded by a coiled spring 51 into engagement with the keeper 31. In the engaged condition of the assembly the hook 100 is received in an aperture 103 in a plate member 15 which carries the keeper 21 and it is urged to this position by a spring 93. The operating lever is provided with a handle 85 adjacent the hook 100. Reference has been directed by the Comptroller to Specifications 693,341, 733,985 and 750,945.

Title: Improvements in photographic cameras having multiple objectives
IPC: G03B15/00
Filed: 1954-08-19
Abstract: 767,618. Photographic cameras. MONTREMY, J. DE. Aug. 19, 1954 [Aug. 21, 1953], No. 24227/54. Class 98(1) In a camera which may be used for aerial survey, having a pair of objectives 4, 4a and a single spring driven shutter, a motor driven cam shaft 40 operates the shutter release, lifts the presser plate 16 and rewinds the shutter spring 20. Preferably, the shutter re-winding and the film transport are operated from shaft 40 through a Maltese cross mechanism 46, 47. As shown spring 20 is rewound through half a revolution after each exposure by sprocket wheel 56 through chain drive 57 and the film feed is simultaneously operated by the drive through pinions 59, 60, 61 and 62. The Maltese cross mechanism is so arranged that shaft 53 moves with shaft 40 for half a revolution of the latter and remains stationary for the following half revolution during which time the shutter is released by cam 41 closing microswitch 67 and so completing the circuit of electromagnet 29. Armature 30 is attracted by the magnet and centrally pivoted lever 31 moves plate 25 so that abutment 26 on block 28 is removed from the path of pin 32 on the shutter which is thus free to rotate under the action of spring 20 through half a revolution, the rotation being stopped by pin 33 engaging abutment 27. On de-energizing electromagnet 29, plate 25 is returned to its original position by spring 31a and pin 33 then falls against abutment 26. The shutter has a pair of sector shaped blades 5, 5a each consisting of two relatively adjustable vanes and, during the exposure, the blades interchange their positions in front of the objectives 4, 4a. Cam 42 operates slides 65 and, through centrally pivoted lever 66, lever 17, which raises the presser plate 16 to free the film 7 held between it and transparent plates 10 and 12. Shaft 40 is driven from motor 34 through a worm drive to a worm wheel on shaft 35. The film 7 passes from supply spool 8 over freely rotatable rollers 9, 11 and 13 and, from drive roller 14, to take-up spool 15. Cam 43 operates micro-switch 68 which may be used to operate an exposure counter. The relative angular positions of the vanes of the shutter blades 5, 5a are adjustable by knob 24 which is rotated as part of the shutter. Pins 21, 22 may thereby be withdrawn, against spring 23, from one pair of holes in plate 2b and plate 2a turned so that they engage an angularly spaced pair of holes in plate 2b.

Abstract: 893,800. Electric heating elements. BRITISH INSULATED CALLENDER'S CABLES Ltd. July 13, 1960 [July 14, 1959], No. 24237/59. Class 39(3) An electric heating element consists of a length of insulated wire folded on itself at its midpoint and the halves placed side by side and enclosed in a single lead sheath, the insulation being provided by applying two or more layers 2, 3, 4, Fig. 1, of glass fibre as helical lappings with alternating directions of lay, and after each layer has been applied impregnating it with an insulating compound and burnishing its surface. The glass fibre is applied in the form of a composite yarn or roving. In one embodiment the insulation is applied as a roving built up from a number of strands of 130's count in the glass system, e.g. one of the kind designated as 130/40. Composite yarns of counts 225/2/3 and 150/2/2 may also be used, but the use of yarns with a count number greater than 300 should be avoided. The resistance wire 1 may be of 0À036 inches diameter and insulated by three 130/40 rovings, the 40 continguous glass fibre filaments preferably being "untwisted". The composite layer thus formed has a radial thickness of 40 mils. A suitable length 5, Fig. 2, of insulated conductor (e.g. 220 ft.) is folded on itself at its midpoint and the two halves are enclosed in a lead sheath 6 formed by extrusion. The end 7 of the sheath is shaped to form a cap over the conductor 5 and soldered to form a waterproof covering therefor, the free ends 8 and 9 of the conductor being left uncovered to enable current to be supplied to the element. The transverse cross-section of the element may be a flattened oval, a "Figure 8" or a dumb-bell. The element may be used in a floor heating system or for pipe heating.

Abstract: 837,263. Mixing liquids. A'BECKETT, W. J. Aug. 5, 1958 [Aug. 21, 1957], No. 25009/58. Class 86 An apparatus for mixing liquids of different temperatures to provide a constant temperature effluent has a mixing chamber 4 with hot and cold inlet ports b, 7 respectively and an outlet port 10 (Fig. 1, not shown). A piston valve 11 with radial ports 12, 13 is constrained at its upper end by a flexible diaphragm 3. The radial ports 12, 13 are so arranged that when the valve is at the lower end of its travel hot water may pass from the inlet port 6 and its associated annular groove 8 through ports 12, 13 into the bore 14 of the piston valve 11; as the valve rises the ports 13 make register with the cold water inlet 7 and its associated groove 9. When the apparatus is connected to sources of fluid supply hot and cold water pass by ports 12, 13, the bore 14 and passages 27 to mixing chamber 4. Cold water also passes through passages 20, 21 to the chamber 5 above diaphragm 3 which is depressed by the fluid pressure depressing piston valve 11 admitting more hot water to mixing chamber 4. When the temperature therein rises above the desired limit the thermosensitive metallic spiral 24 operates control rod 25 opening ball valve 27 allowing fluid to pass from chamber 5 through passage 28 and slot 26 to chamber 4. releasing the pressure in chamber 5, when piston valve 11 will be urged upwards by spring 15 admitting less hot and more cold water. The passageway 21 is provided with a pressure relief valve 23 to ensure constant pressure in chamber 5. The temperature at which valve 27 opens may be adjusted by an adjusting screw 29 having a tapered nose bearing or control rod 25 and operated by an external knob 31 which may have a pointer and scale.
