Abstract: 706,864. Severing by grinding. EYELET CO., Ltd. G.T., and HENSHAW, J. N. Aug. 25, 1952 [Aug. 25, 1951], No. 20053/51. Class 60, [Also in Group XXV] The mandril 138, Fig. 1, of a blind rivet 132 is severed by a tool comprising a grinding wheel 138 mounted on a body member 40 which moves in relation to a base member 20 when a handle 54 is depressed. The base member 20 is provided with rubber pads 28, 30, Fig. 2, and metal side ribs 24, 26, to engage the riveted plates 100, 130. The handle is loaded by a spring 72 and' swings about a pivot 62 to displace a pivot 60 and the member 40 forwardly, the grinding wheel 88 severing the mandril 138 flush with the head 133 of the rivet. During this operation, the mandril is held in a semi-circular recess 118 situated at the end of an aperture 34 in the base member. The grinding wheel 88 is secured by cement to a metal disc 102 rotated by an air driven spindle 86 mounted in a casing 84 adjustably clamped by a bolt 92 to the body member. After severing, the upper portion of the mandril is ejected through an opening 106 by the action of the wheel 88 and compressed air passing through vents 110. To prevent sudden and accidental engagement of the grinding wheel with another mandril after the severing operation has been completed, a guard element 120, Fig. 6, engaging an inclined groove 126 in the base member 20 and a transverse groove 127, Fig. 7, in the member 40 is moved into a position across the aperture 34 when the member 40 is advanced. The grinding wheel is driven at approximately 10,000 r.p.m. Specifications 348,818, 504,928, 602,652 and 627,618, [all in Group VII], are referred to.

In a railway block signalling system having stations AB and CD at the ends of a block section and wherein the starting signal B or C is returned to stop and locked during or after the entry of a train into the block section and cannot be unlocked to be set at " clear " until an indication that the section is clear is received, there is provided a device operative on the return of the train from the section to the entry station, e.g. A, B, for giving the " section clear " indication and comprising two electrically-connected members a and b located one at each station, the one a at the entry station AB, being operative by the train when the home signal A for the returning train is at " clear " to return the exit traffic control equipment BA at the entry station AB to normal or at rest condition and to cause the member b at the section exit station CD to effect the return to normal or at rest condition of the receiving traffic control equipment DE at the exit station. The two members a, b may be connected by a  track circuit, e.g. an existing one utilizing D.C., in which case a distinguishing current such as A.C. is applied at the entry of the section with an A.C. responsive relay at the exit end of the section. Alternatively a wire circuit is provided between the two members a, b, as shown. In either case, the circuit may incorporate an electrical keyboard lock circuit, the relay IS1 being operated by the train as it enters the insulated track section I1 arranged ahead of the station AB for traffic from CD to AB and operative only when the home signal A is at "clear." Such a relay as IS1 may be connected automatically or manually to operate the device a when a train enters the section I1 on return to the station AB, the exit traffic control equipment BA in turn operating the device b to effect control of the traffic receiving control equipment DE at station CD to return to its normal or at rest condition. Alternatively a relay distinct from the track relay or keyboard lock relay may be provided operable automatically by the train, or manually, to reset the desired traffic control equipments. The invention is also described as applied to both-way single track operation.

Abstract: 706,217. Bins for waste matter. TAYLOR, R. March 21, 1952 (Aug. 28, 1951], No. 20236/51. Class 26 A bin for waste matter, having a normally closed lid and a receptacle for a deodorizing substance, is provided with visible means to indicate a predetermined loss of weight of the deodorizing substance. As shown, the bin comprises an outer casing 21 with a pivoted lid 27, 28 operated by a pedal 39, an inner container 10 with a handle 19, and a perforated receptacle 13 for the deodorizing substance 34. The lid portions 27, 28 overly and underly, respectively, the rim 25 of the outer casing 21, and are joined by a stepped portion 29 to which the lid-pivot pin 30 is secured. The receptacle 13 is hinged at 35 to the smaller lid portion 27 and is held in position by a resilient clip 36. Loss of weight of the deodorizing substance 34 therefore allows the lid to tilt into the dotted line position, thereby providing a visible indication. Depression of pedal 39 raises a rod 41 carrying a roller 44 which freely engages the lid portion 27 for normal use of the bin. The inner container 10 and outer casing 21 are retained in assembled relation by means of a pivotally mounted U-shaped handle 46 with bolt elements 47 extending through registering holes 48, 49. As a modification, the visible indication may be furnished by observing the position of the receptacle 13 through a window in the outer casing 21.

Title: Method and system for tracking a selected image portion of a moving object
IPC: H04N7/00
Filed: 1975-05-14
Abstract: 1483020 Television NISSAN MOTOR CO Ltd 14 May 1975 [20 May 1974] 20299/75 Heading H4F A system for reducing smearing of moving images (e.g. when observing the occupant of a moving vehicle during a head on collision) comprises two image pick-up tubes 10, 11 each having a photo-electric conversion target 12, 13 receiving the same image scanned by an electron beam, wherein the beam in the first tube scans the whole target area and produces a bright spot corresponding to the position of the image of a light emitting or reflecting marker (51, Fig. 4a, not shown) which spot initiates a pulse in peak detector 22 which is translated to a set of position co-ordinates to deflect the electron beam of the second tube to the spot corresponding to the position marker, which beam then scans a reduced area of the target at the same line and frame scan rate as the first tube so that the speed of the beam across the target is slower than in the first tube and hence the target potential is reduced more quickly, so reducing smearing. Since the position marker has finite size, more than one "peak" will be directed (i.e. in successive lines) but only the first is passed by "one pulse gate" 23 (Fig. 6, not shown) to a monostable multivibrator 24 which produces a short pulse which in turn enables switching gate 25 to sample the instantaneous voltage in the horizontal sawtooth generator 20. The sampled voltage is converted to an 8 bit digital signal, stored in memory 28, converted back to an analogue signal and output to the horizontal deflection coils 17H throughout one frame so that the horizontal scan, produced by sawtooth generator 30, is positioned on the target. The slope of the waveform output from generator 30 is smaller than that from generator 20 so that a reduced area of target is scanned (Figs. 5a and 5b, not shown). Vertical positioning and deflecting of the beam are achieved by a similar circuit. The horizontal and vertical sawtooth generators 30, 37 are triggered by monostable circuits 24, 31. The vertical blanking pulse generator 38 clears digital memory 28 and one pulse gate 23 so that the position of the marker in the succeeding frame can be determined. The first tube may be moved to roughly follow the moving image, by an operator using utilization circuitry 40. The signal produced by the second tube may be stored by recorder 38 for later display on a TV screen 39.
