Title: A seat belt retractor assembly
Inventor: FISHER ROBERT CRIPPS
IPC: B64D25/06
Filed: 1969-09-08
Abstract: 1283709 Spring drum apparatus R C FISHER 8 Sept 1969 [11 Sept 1968] 44377/69 Heading B8B [Also in Division A3] In a safety belt retractor, in which the belt is wound on reel 22 by means of spring 16, edge cam 38 is normally prevented from being rotated, together with the reel 22, by the engagement of projection 94 with either end of slot 92. When the reel 22 is being moved initially, after a change in direction of rotation, it carries the cam 38 with it, by means of an annular clutch surface, for the length of slot 92. At both its terminal positions, cam 38 blocks the engagement of locking bar 98 with teeth 114 on the reel flanges, by lobe 168 on 166 engaging tooth 106 of bar 98. After extending the belt, locking is effected by allowing a slight retracting movement, to free bar 98 from lobe 166, for movement into the locking position, by spring 146. When the reel has been locked, the belt may be extended further by first retracting it almost completely, so as to position gear ring 134 with its blocking projection 156 in contact with tooth 112 of bar 98. Cam 38 then moves freely into the terminal position, in which lobe 166 is operative to obviate locking. The position of bar 98 can be manually controlled by knob 120.

In a system wherein a main load 2 and a load 1 liable to fluctuation are connected to a common supply source 3 and wherein the two loads are connected to the source by way of a tapped reactor 5 so that the fluctuating load 1 does not cause variations in the voltage applied to the main load 2, the voltage drops introduced into the two load circuits are compensated by the addition of a series capacitor C1 or C2 into each load circuit, the values of the capacitors being determined inter alia by the turns ratio of the reactor 5. In some cases one capacitor only may be used when compensation for volt drop in one of the load circuits is unnecessary. In alternative arrangements impedances equivalent to the reactor 5 are inserted into each load circuit or two reactors may be used, one in each load circuit.

Abstract: 996,669. Pulse modulation circuits; transistor pulse circuits. MATERIEL ELECTRIQUE S.W. Nov. 22, 1963 [Dec. 28, 1962], No. 46180/63. Headings H3T and H4L. [Also in Division G4] In a circuit for converting a varying input voltage into a corresponding variation of pulse repetition frequency, the pulses then being counted over a predetermined period, the input signal E is supplied via a resistor R1 to charge a capacitor C in the base circuit of a unijunction transistor T in a relaxation oscillator circuit. As soon as the charging voltage reaches a limit Vp dependent on the characteristics of the transistor T, the capacitor discharges rapidly via transformer N and produces a short duration pulse in the secondary winding, the repetition rate of these pulses varying linearly with the voltage E. The resistance R2 is arranged to compensate for temperature variations. A normally non-conducting transistor T1 allows a capacitor C1 to be charged to substantially a voltage V2 via resistors R5 and R7, application of a pulse from the transformer N to the base of the transistor T1 causing T1 to conduct and quickly discharge the capacitor C1 through resistor R6 and diode D2. This causes a transistor T2 to conduct and transistor T1 having ceased to conduct due to the termination of the short input pulse, the capacitor C commences to recharge, the transistor T2 ceasing to conduct when the capacitor is recharged to the voltage V2 and the cycle being repeated. A counter A counts the number of pulses in a predetermined time.

Title: Undertrimmer mechanism in a sewing machine

Filed: 1970-10-01
Abstract: 1321246 Trimming mechanism SINGER CO 1 Oct 1970 [7 Oct 1969] 46701/70 Heading DIG  A sewing machine work trimming mechanism comprises a blade 119 co-operating with a ledger blade 121, means being provided to vary the amplitude of oscillation of the blade simultaneously with a variation of the vertical position of that blade. Oscillatory motion of the cutter blade 119 is provided by a bed shaft eccentric mechanism 31, 32 connected to the centre of a driving lever 34 the ends of which are respectively coupled to a crank arm 49 on a rock shaft 52 and a slide 40 on a pin 42 carried in a tiltable yoke 43. A further crank arm 55 on the rock shaft 52 is connected to one end of an arm 59 of a bell crank lever 60 pivoted at 61 to a lever element 89 urged against a spring biased pin 99 by a finger 93 on a control shaft 80. The other arm 62 of the bell crank lever 60 carries the blade 119 for co-operation with a ledger blade. A cam 74 rotatable by a handle 71 presents a notched cam track 76 to a follower 77, 78 secured to a control shaft 80, a selected position of the cam thus turning the control shaft to a corresponding angular position, a linkage (83, 86 Fig. 5 not shown) connecting the shaft 80 to the yoke 43. Angular movement of the shaft 80 by movement of handle 71 thus tilts the yoke 43 to set a particular cutter stroke and, through lever element 89, moves the centre of oscillation of the bell crank lever 60 and thus the vertical elevation of the cutter blade 119. In this embodiment the effect is to maintain the lower position of the blade irrespective of the stroke set (Figs. 11a-d not shown). A ply separator (113, Figs. 9 and 10 not shown) has a hook shaped end and is interposed between two plies to be stitched to raise the upper ply so that only the lower ply is severed.

Title: Method and apparatus for fingerprint identification
IPC: G06V10/88
Filed: 1973-10-09
Abstract: 1399675 Fingerprint recognition systems SPERRY RAND CORP 9 Oct 1973 46963/73 Heading G4R An optical processor for use in fingerprint identification determines the angular direction of the ridge lines at each of a number of spaced small areas of the print. The principle of operation is illustrated by Fig. 1. The fingerprint is, in this embodiment, a transparency occupying the field 10<SP>1</SP>. Coherent light is directed through the transparency and forms a fourier transform at the focus of lens 13. The transform consists of an undiffracted central spot surrounded by an annular band formed by the lobes of the diffracted components. For example, any small area of the print having vertical ridges will provide two diffraction lobes 12d, 12d<SP>1</SP> on a horizontal axis irrespective of the position of the area within the print. A rotating mask 19 is placed in the transform plane. It is opaque except for slit 19<SP>1</SP>. Light passing through the slit is directed by lens 18 to photosensors 16a, 16b,..., each of which can receive light from only a corresponding area 12a, 12b, ... of the print. For example, sensor 16d will receive light from area 12d, but only when slit 19<SP>1</SP> is aligned with either of diffraction lobes 12d<SP>1</SP>. Mask 19 has peripheral timing slots (not shown) which increment a counter such that the counter output is indicative of the instantaneous angular orientation of the slot. When a photosensor provides an output pulse the present count is read in to an associated register so that at the end of a half revolution of the mask, each register will contain an indication of the orientation of the ridge lines at the corresponding small area of the print and may be used for identification purposes. In an alternative arrangement, Fig. 4, a live finger F is used. Coherent light directed on to the finger forms a fourier transform at 32. The transform is imaged on to a rotating mirror 33 which has an opaque bar across its diameter. The light intensity at a photosensor 34 of an array of sensors will therefore fall when the orientation of the bar is perpendicular to the ridge lines at the corresponding small area of the fingerprint and is used to read a count in to a register as described above. Reference is made to the use of a sawtooth generator instead of the incrementing counter, to the use of an oscillating mirror to compensate for off-centring of the print, and to serial rather than parallel operation.
