Title: Improvements in apparatus for conforming shoe uppers
IPC: A43D119/00
Filed: 1959-05-22
Abstract: 963,972. Shoe making apparatus. W. G. HAWKINS. Aug. 19, 1960 [May 22, 1959], No. 17458/59. Heading A3B. In a shoe upper conforming apparatus comprising a last 1 and support 10, and a plurality of poweroperated grippers 6, pulling-over movements of the grippers on the upper 9 are controlled by affixing to the upper a patch 5 which carries a fluorescent pattern which, when the upper 9 has been pulled over to an optimum position, is detected by a sensing system comprising photoelectric cells 13 and movement of the pulling over grippers 6 is then arrested. The cells 13, which correspond severally to the grippers 6 and are housed in a sensing head 8 above the upper, cause a current change which is amplified by a phase-sensitive detector 14 and then fed to relay amplifier equipment 15 which in turn operates a series of gripper relays 16 connected severably to solenoid type flow control valves 17 controlling the supply of pressure fluid to the grippers 6. The phase detector 14 is energized by a reference signal derived from a photo transistor 18 exposed to a mercury vapour lamp 19 to constitute a normal. Each gripper mechanism preferably consists of a single-acting hydraulic device comprising a cylinder 20, a slidable piston 21 and pincers 22. In operation, the upper and last correctly positioned, start button 25 is closed to energize a self-holding relay 26 and thus operate a solenoid valve 27 to direct pressure fluid first to pincer control valves 28A, 28B and then to the solenoid valves 17 to retract the pincer carrying pistons 21 and commence the lasting operation. The latter having been completed wiper blades 12 advance and swing in and simultaneously the grip of the pincers 22 is progressively released.

Title: Stitch, length and time counting device for machine supervision, for sewing and like machines
IPC: D05B81/00
Filed: 1931-06-16
Abstract: 389,797. Sewing- machines. DœNHÍLTER & SCHÍLZEL, 5, Neue Jakobstrasse, Berlin. June 16, 1931, No. 17509. Convention date, March 5. Void [Published under Sect. 91 of the Acts]. [Class 112.] A plurality of registering mechanisms is combined with a sewing-machine to ascertain the length of stitching worked by the machine with different length stitches and the time during which the machine is idle for replacement or turning of the work. As shown a flexible shaft 1, Fig. 1, connected to the sewing-machine shaft drives, through worm gearing 2, 3, and friction clutch, a shaft 4 carrying a number of bevel gears 5 .. 9 any one of which can be coupled to a corresponding one of a number of bevel gears 10 .. 14 driving counting mechanisms 15 ..19 one for each stitch length. The adjustment of the stitch length is effected by a knob 20 co-operating with an indicator (not shown) and adapted to rotate a shaft 21, Figs. 2 and 3. The shaft is provided with an eccentric 22 carrying adjustable segments 23 .. 27 for co-operation with a finger 28 on a lever 29 connected to the stitch setter 32 of the machine. The shaft 21 also carries a set of cams 33 .. 37 on which bear blade springs 38.. 42 adapted to maintain the bevel gears 10 .. 14 in inoperative position. The cams have each a flat face and these are arranged in a spiral manner so that when a blade spring rests on its flat surface the corresponding pair of bevel gears are engaged to drive the counter. The shaft 1 also drives through a friction coupling a disc 49 which lifts a rod 50 and rocks a bell crank 51, 52 so as to cause a curved blade spring 53 to bear against the escapement of a clock mechanism 48. The clock is thus stopped when the machine is operated but when the machine stops, to enable the work to be folded or turned, a spring 55 retracts the lever 51, 52 and the blade spring gives an impulse to the escapement to set the clock going, thereby giving an indication of the time spent on changing work &c. To render the registering device inoperative a shaft 56 is operated and a cam 61 thereon rocks a bell-crank lever 63 and a pin 64 on the end of one of the arms locks a ratchet wheel 65 that is secured to the shaft 4 whereby the shaft is stopped, the friction drive through the worm gearing 2, 3 and spring 66 being ineffective. At the same time a pin 67 rotates the disc 49 to arrest the clock escapement.

Title: Method of and apparattus for interpreting a coded record
IPC: G06K7/016
Filed: 1973-04-11
Abstract: 1427811 Bar code reader MONARCH MARKING SYSTEMS Inc 11 April 1973 [12 April 1972] 17523/73 Heading G4M [Also in Division H3] A record having bar code markings in which a wide bar or space represents " 1 " and a narrow bar or space represents a " 0 " is read by an optical or magnetic reader having a reading aperture of known size. Pulses from the reader 14 are amplified 20 and fed to upper and lower level detectors 32, 34 fed with reference voltages from a voltage divider coupled to a unit determining average pulse height 30. As the first bar is read a ramp signal is fed to the detectors (Fig. 3, not shown) and as the lower level is reached AND gate 62 is enabled to cause pulses from clock 68 to be fed to counter 52. When the higher level is reached the count to counter 52 is stopped. Pulses are also fed via a divider 72 to a bar width counter 50. At the trailing end of each bar a further ramp signal is obtained. AND gate 62 is enabled and flip-flop 44 enables gate 82 to feed pulses to counter 48 and stop pulses to counter 50. Flip-flop 42 also changes state and pulses are fed to counter 46 until the lower level of the slope is reached (Fig. 4, not shown). The values in counters 46, 52 are dependent on the speed of scan across the record and the diameter of the opening in the reader. The constant K is determined so that the count in counters 46, 52 is smaller than the count in counters 48, 50 if a wide bar or space is read and larger than the count in counters 48, 50 if a narrow bar or space is read. The values for the bars and spaces are compared by subtraction in address 108, 86 and a corresponding " 1 " or " 0 " value is fed to shift register 92. A mod 6 counter and decoder 40 determine that a binary coded decimal number is read.

Abstract: 1375234 Photo-electric particle number measurement COMMISSARIAT AL'ENERGIE ATOMIQUE 17 April 1972 [22 April 1971]  17721/72 Heading G1A A device for determining the number of small particles in the atmosphere comprises a pneumatic assembly in which air is drawn through a moistener into a cylindrical measuring chamber having dry walls the ends of which are closed by ports, and then subjected to an adiabatic expansion to cause water to condense on the particles and an electronic assembly comprising a light projector and a photo-conductive cell arranged opposite the ports of the measuring chamber and a storage and comparison device by means of which the outputs of the cell before and after the expansion are compared to produce a measure of the number of particles. As shown, Fig. 1, the measuring tube 3 is arranged horizontally and comprises a measuring chamber 5 provided with transparent end ports and surrounded by a spongy material (53) enclosed in a tube (41) partially filled with water and having a semi-cylindrical passage 55 through which the air is drawn. The moisturizer passage 55 is connected via a valve V 1  to the inlet of the measuring chamber 5 the outlet of which is connected via a valve V 2  and a choke 13 connected in parallel with a by-pass valve V 3  to a vacuum source 9 which is connected via valve V4 to a pump 11. The projector 29 comprises a lamp and an optical system to produce a homogeneous cylindrical beam which passes through chamber 5 and is detected by photo-conductive cell 31. The lamp is provided with a regulated D.C. voltage supply and the cell with a constant current supply the value of which may be adjusted for different ranges of particle numbers. The output of cell 31 is applied to a measuring device 33 to provide an output to meter 37 and to a recorder (not shown). A sequence controller 35 operates the solenoid valves V 1  -4  by means of thyristors and also controls the measuring device 33. Operation sequence. Valves V 1  ,2  and  4  are opened and air is drawn in through port 19 moisturized in tube 55 and enters measuring cylinder 5 the source 9 being partially evacuated due to the constriction 13. Valve V 2  is then closed so that the source 9 is completely evacuated. Valves V 1  and  4  are closed and the output of cell 31 is measured and stored to produce a reference level. Valve V 3  is then opened to cause the adiabatic expansion of the sample, the water vapour condensing on the particles to produce a change in the light absorption and dispersion. The maximum value of the photo-cell output is measured and placed in a second store and the two stored values are then compared by means of a differential amplifier to produce an output. After the second measurement has been taken the temperature of the sample rises due to conduction through the walls of the tube and the water droplets revaporize so that the walls of the chamber are kept dry.
