Title: Electronic Multi-Station Inspection Apparatus.
Inventor: QUINN RICHARD MONROE
IPC: B07C5/00
Filed: 1968-04-09
Abstract: 1,176,747. Photo-electric defect detection. BALL BROS CO. Inc. April 9, 1968, No.16893/68. Heading G1A. Defects in objects are detected photo-electrically, an object being passed through a number of photoelectric defect detection stations in succession and the presence of a defect in the object detected at an earlier station or earlier stations being stored electronically, so that when the object has passed through the apparatus to a 'pass' or 'reject' station, if a defect has been detected at any of the detection stations, the object may be rejected. Photoelectric means is also provided for sensing the position and movement of an object from one station to the next and also to control shifting of fault information from one storage circuit to the next. The arrangement described has three detection stations operating by reflection from or transmission through an object of light from a source (not shown). A photo-cell (12) senses transfer of an object from one station to the next and thereby sets off a sequence of time displaced signals. An inspection pulse is produced from a bi-stable multi-vibrator (56) and subsequently scan and delayed scan signals from mono-stables (83) and (84). The presence or absence of a fault as detected by a first photo-cell (13) is held in a first bi-stable circuit (98) and then transferred to a first memory bi-stable (115). The same occurs for the second detection station except that the information held in its (the second) memory bi-stable (134) is modified by that held in first bi-stable (115) i.e. if a fault was recorded at the first detection location (in first memory bi-stable) this is transferred to the second memory bi-stable. The output of the third photo-cell (15) is used to modify the information stored in memory bi-stable (134) if this is not already recording a fault. A final signal from the position photo-cell causes the second memory bi-stable to be read out and control a pass or reject circuit, including a mono-stable delay circuit and relay. Circuits diagrams are given for amplifiers (for photo-cell outputs) Fig. 3; mono-stables, Fig.4; an inverter, Fig. 5; AND-gate, Fig.6; bi-stables, Fig. 7; an inhibit circuit, Fig. 8; relay control circuits, Fig.9 (none shown).

Title: Improvements in or relating to machines organised for applying a ribbed strip to insoles for shoes
IPC: A43D43/00
Filed: 1961-05-10
Abstract: 981,401. Attaching ribs to insoles. BRITISH UNITED SHOE MACHINERY CO. Ltd. May 10, 1961 [May 12, 1960], No. 16914/61. Heading A3B. A machine comprises means for feeding and attaching a ribbed strip S to the margin of an insole I, said means 32 pressing the strip at successive points against the insole and a mechanism, which under the control of a control member 250 movable by operator actuated means into a position resting on the rib, acts to stop said feeding and attaching means 32 automatically by movement of the control member off the rib. A hand lever 212 connected to an edge gauge 160 by a series of pivoted members 186 positions the gauge 160 to shift the insole relative to the attaching and feeding member 32 to vary the distance of the strip inwardly of the insole edge. The control member to stop the feeding and attaching operation consists of a finger 252 normally held in parallel relationship with a second finger 250, the finger 252 carrying a switch 308 held open by the finger 250 when parallel therewith. During the operation, starting at the heel breast line, the fingers are held just above the upper surface of the insole inward of the rib. When the operation reaches the ball position at the first side of the insole the hand lever 312 is moving about a vertical axis 198 to move the edge gauge 160 so that the strip is attached close to the edge of the insole I. The lever 212 is swung a second time when the operation reaches the tip of the insole so that the strip is attached further in from the edge and a third time at the ball line on the opposite side of the insole to attach the ribbed strip close to the edge. To swing the lever 212 back to its initial position i.e. the third swing, it must be depressed at the same time so that a latch 214 provided on the lever 212 can be disengaged from a recess 232 formed in a bearing sleeve 224 provided about the axis 198, thereby disengaging a microswitch 300 carried by the lever 212 from a stop 304 carried by a collar 208 to which the lever is pivoted for heightwise movement, to energize a solenoid, the plunger 288 of which is connected to the finger 250 by a wire 280. The plunger 288 moves downward so that both fingers move into a position on the rib at the side of the insole I to which the rib was first attached. During the remainder of the operation the fingers ride on the rib until one finger 250 drops off the end whereupon the switch 308 is closed and energizes a solenoid 314 which is connected to the upper end 74 of a two part treadle rod 74, 76 to disconnect the treadle and disengage a clutch which controls the insole and strip feeding mechanism and at the same time a severing knife is automatically operated to sever the strip. The machine is provided with an adjustable heel gauge 102, which is connected to the treadle, depression of which starts an attaching operation and moves the heel gauge to an out-of-the-way position. Specifications 558,641, 651,635, 707,899 and 936,795 are referred to.

Title: Improvements in priming arrangements for centrifugal pumps
IPC: F04D13/14
Filed: 1952-07-07
Abstract: 727,050. Centrifugal pumps. DRYSDALE & CO., Ltd., and YOUNG, J. July 7, 1953 [July 7, 1952], No. 16981/52. Class 110 (1). A priming arrangement for a centrifugal pump comprises a supplementary 'impeller driven from the main driving shaft of the pump and interposed between the main suction pipe of the pump and an air or gas exhauster. The shaft 5 of the supplementary impeller 4 is driven through bevel gearing 6 from an extension 3 of the shaft 2 of the centrifugal pump 1. Gas or air is drawn by an exhauster 13 from the main suction pipe 9 by way of vents 9a, a stopvalve 8a, the impeller 4, and pipes 11 and 12. The impeller 4 allows the passage of the air or gas, but rejects the liquid when the latter eventually rises to the level of the impeller. Liquid is thus prevented from reaching the exhauster 13. In the event of the exhauster being started up before the main pump 1 or of the latter inadvertently stopping while the exhauster is still running, a float-operated valve 15 opens a connection to atmosphere and breaks the vacuum, thereby preventing the liquid from reaching the exhauster 13. The pump 1 may have a vertical shaft, with the impeller 4 located at the driving end of the shaft.

Abstract: 426,235. Brakes. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London. June 8, 1934, No. 17045. Convention date, June 8, 1933. [Class 103 (i)] Means for arresting a rotatable member in a predetermined angular position after declutching from the motor by which it is driven comprises a conducting disc 30 rotating with the member between the poles of an electromagnet 32 so as to give an eddy-current braking action and an insert 31 of magnetic material on the disc which when the speed has been sufficiently reduced comes into alignment with the poles. The angular position of the insert on the disc may be adjusted in a slot 36 in the disc. The device is shown upon the shaft 24 of the rotor 12 of a position determining device 10 forming part of a device for establishing a predetermined relationship between the end of a strip of material 19 and the angular position of a flying shear 18a whereby the shear may cut off predetermined lengths from the strip as described in Specification 426,236, [Group XXXVII]. When the end of the strip, driven by a motor 15, engages the switch 20 the magnetic clutch 22 is energized to drive the shaft 24. A differential device compares the position of a position-sending device driven by the motor 20b of the shear 18a with the position of the rotor 10 and varies the speed of the motor 20b until the positions of the two positioning devices correspond. When the trailing end of the strip leaves the switch 20 the clutch 22 is de-energized and the magnet 32 is energized, so that the rotor 12 is arrested in a predetermined position by the disc 30.
