A vehicle seat includes a safety belt comprising an automatic winder 31 mounted on the seat frame and from which extends a belt 32 passing over the seat back to a mounting 33 on the seat frame or the vehicle, the belt in use being extended to form lap and diagonal lengths 32V, 32D and being caused to pass around a finger 38 which is locked to prevent release of the belt by a cranked handle 42, the end of the belt adjacent the winder being also locked to prevent further unwinding by being clamped between a cam 44 and a stirrup 37, the stirrup being held in place by fingers 39, 40. In a further embodiment the winder 66 rotates with a spindle 67 which can be locked when the belt is in use by a lever 73 engaging a ratchet on the spindle, the lever being held in contact with the ratchet by a spring loaded pawl 75, with the belt passing around the lever. In a modification, Fig. 3, the spindle is formed in two parts and when the lever is locked in position by the pawl the adjacent ends of the spindle are locked against rotation by interengaging teeth. In a further modification only a lap length of the belt is formed and it is the end of the belt remote from the winder which engages the lever 73. In the embodiment of Fig. 12 the end 60e of the belt is adapted to be locked around pawl 110 by a bolt 111 operated by a hand lever 114, the pawl moving to a position where it can be engaged by the bolt during unwinding of the belt by means of a rack and pinion 105, 106.

Abstract: 1490807 Connector AMP Inc 18 Nov 1975 [12 Dec 1974] 47403/75 Heading H2E [Also in Division B3] A connector has a housing 24 of insulating material, having a plurality of cavities 44 extending between opposed first and second surfaces of the housing and a respective electrical contact 26 received in each cavity, each contact having at one end a pin 62 extending from the first surface for insertion into an aperture of a pcb and at the opposite end a pair of spaced opposed contact arms 64 which extend at least partially from the second surface for electrically engaging a wire, e.g. 12, 18, positioned between the arms, and a flange, e.g. 32, 34, having slots 36 for accommodating part of the wires, e.g. 12, 18. In an embodiment (Fig. 1) the connector has a cover 28 and is used for connecting a ribbon cable 10 to a pcb 76 (Fig. 5). The housing 24 is made of flame retardant nylon and has a plurality of grooves 42, each communicating with an individual cavity 44. Each contact 26 has lances 68 and a stop 70. To assemble the connector, the contacts 26 are pushed into cavities 44 so that arms 64 are flush with surface 38; pins 62 are then soldered to the pcb 76 and the wires 12, 18 of cable 10 are combed, and pushed down slots 36 with their free ends protruding beyond the surface 39. An upper die 82 (Fig. 3) engages the housing 24 and as it moves down it firstly bends the free ends of the wires into grooves 40. A lower die (90, Fig. 4, not shown) engages the underside of pcb 76. Further movement of the upper die will force the housing 24 completely on to contacts 26 and wires 12, 18 will be forced into slots 72 (Fig. 5). Finally the cover 28 is secured to the housing by pressing legs 55 in recesses 50. To remove the cover 38 a tool (not shown) can be inserted into the apertures 60 to flex legs 55 outwardly. In alternative embodiments, one or both of flanges 32, 24 may be omitted, the grooves 42 may be omitted, or grooves could be provided on the lower surface of the cover 28.

Title: Process for finishing float glass
IPC: C03B18/02
Filed: 1963-12-03
Abstract: <PICT:1019415/C1/1> Float glass is finished by dissolving at least a portion of the surface which was in contact with supporting liquid. The dissolution reagent may be aqueous hydrofluoric acid with or without fluorosilicic acid.  The total concentration of these acids should not exceed 50% by weight of the solution.  The solution may contain tin, dissolved from the glass, in amounts from above 0.05 to below 5% by weight.  Exemplified temperatures of the reagent solution are 70 DEG  F. and 120 DEG  F.  Treatment is preferably terminated before a depth of 3 microns of the surface glass has been removed. The glass may be supported during treatment on rollers which may be e.g. of rubber.  In the Figure is shown a portion 1 of a continuous cooled and washed float glass ribbon from the float tank, the float surface being the underside. Acid solution is fed through 5 to basin 4 having inner rim 6 the inner perimeter of which defines an inner tank, which may be wider or narrower than the glass ribbon.  The solution overflows from the inner tank between the glass and rim 6 into gutter 7, so that the entire lower surface of the glass ribbon over the inner tank remains in contact with the liquid.  The reagent solution is subsequently removed from the glass by squeegee 11 and water spray 12, and wash water is removed by squeegees 13 and 14. The resultant surface is more readily polished by abrasion than the original float surface, and the treated glass on bending is free from iridescent defect.

Title: Device for indicating digitally a photographic exposure parameter
IPC: G03B17/06
Filed: 1975-11-20
Abstract: 1530616 Digital exposure indicator ASAHI KOGAKU KOGYO KK 20 Nov 1975 [22 Nov 1974] 47732/75 Heading G2A A camera has a digital exposure indicator with means 31, 33 for indicating values of an exposure factor and means 27, 28 for indicating fractions of said values. As shown an AND gate 24 receives inputs from a photometric circuit 21 detailed in Fig. 4 (not shown) and a delay circuit 22 detailed in Fig. 5 (not shown) such that the AND gate 24 remains open for a time t α Ev (exposure value). A multi-vibrator 23 has a frequency such that it generates three pulses in a time corresponding to one Ev step and while AND gate 24 remains open these pulses are fed to a counter 25. Thus the total number of pulses fed to counter 25 equals 3Ev. Every third pulse, counter 25 steps on a counter 29 and when counter 29 reaches ten it steps on a counter 32. Counters 29 and 32 control indicators 31 and 33 which thus respectively indicate the units and tens of the Ev. figure. As counter 25 receives pulses from AND gate 24, it produces successive outputs of 00, 01 and 10 which are fed through an OR gate to indicator 27 and direct to an indicator 28. In this way indicators 27, 28 indicate fractions of an Ev step. For 1/3, indicator 27 is energized; for % both indicators 27 and 28 are energized; and for whole numbers both indicators 27 and 28 are de-energized. In Fig. 1 (not shown), a main indicator (2) indicates diaphragm aperture values and two auxiliary indicators (3, 4) are used to indicate thirds of said values. In Fig. 2 (not shown), a main indicator (12) indicates shutter time values, two auxiliary indicators (13, 14) indicate + 1/3 and + 2/3 of said values and two further auxiliary indicators (15, 16) indicate - 1/3 and - 2/3 of said values.

Apparatus for testing intermeshed gear wheels 18, 22 for total single-flank composite error comprises a rolling disc 13, 27 connected to each gear-wheel and adapted to roll without slip on a respective straightedge 12, 31, and a sliding block 11 mounted on the straightedge 12, the block being guided by a control bar 6 mounted at an adjustable angle on a slide 2. The disc 13 is connected to the gear-wheel 18 via clutches 14, 16 and a gear-wheel 15 to which torque is applied by a motor 38. Similarly the disc 27 is connected to the gear-wheel 22 via a clutch 26 and a gear-wheel 24 to which torque is applied by a motor (40). The centre spacing between the gear wheels 18, 22 is adjusted by a spindle 20 and a hand wheel 21 which move a slide 19 supporting the gear-wheel 18. The straightedge 31 has a block 33 which engages a groove 34 of a control bar 35 so that vertical movement of the slide 2 by a motor 36 causes horizontal movements of the straightedges which magnetically engage the discs 13, 27 to rotate the gear-wheels 18, 22. The control bar 6 is preset at an angle α which depends on the transmission ratio of the gear-wheels 18, 22 and a dial indicator 28 is connected between the shaft 25 connected to the gear-wheel 18 and the disc 27. Errors in the gear-wheels 18, 22 cause relative rotation between the shaft 25 and the disc 27, this relative rotation being shown by the indicator 28. The apparatus may also be used for testing a pair of externally toothed gears by pivoting the control bar 35 through a right angle or by positioning the control bar 6 at an angle α on the opposite side of the vertical to that shown in Fig .1.
