Title: Counting circuit
IPC: G06Q30/00
Filed: 1972-06-23
Abstract: 1399265 Counting; multiplying RANK XEROX Ltd 23 June 1972 29644/72 Heading G4D A counting circuit comprises a pulse generator K1 which is started by each of a series of drive pulses, means for stopping the generator after a predetermined number of pulses and means for supplying the pulses to a dividing circuit (counter) which passes any integral quotient to a further counter and stores the remainder. The drive pulses may correspond to one foot length of a reel of paper and the predetermined number can be altered to change a price weighting factor. Drive pulses set the bi-stable circuit comprising G1 and G2 and start the pulse generator K1. Pulses are fed to counter K2 which produces an output and resets after 40 pulses and the output pulses are gated through K3 to counter CTR4. The pulses are also fed to counter K4 the outputs of which are connected to plug in " billing cards " K5 and K6 which produce an output on all leads to NAND gates G12 or G13 respectively when the counter reading is 53 (K5) or 80 (K6). The output of the counter K4 is also connected to NAND gate G11 whose output changes at a count of 40. Inputs of 0 and 1 at X and Y select one of the three gates G11, G12 or G13 and the output at the selected count is fed to G2 to reset the G1, G2 pair and stop the pulse generator. CTR4 is thus incremented by (on average) X/40 per drive pulse where X is the value to which the selected " billing card " is set.

Title: Method and device for the identification of samples
IPC: G01N35/02
Filed: 1973-06-26
Abstract: 1429052 Identification of samples KOMBINAT MEDIZIN-UND-LABORTECHNIK VEB 26 June 1973 30410/73 Heading G1B In the sampling or analysis of samples wherein the samples are fed in magazines to sampling or analysis apparatus, the sampling or analysis results are correlated to the sample by forming for each sample a recognition character having one or more digits which exclusively indicate the position of the sample within its magazine, and having one or more further digits which exclusively represent the magazine. The recognition character is formed by passing the magazines containing samples through scanning zones and therein subjecting the magazines to light pulses which are partially or completely reflected by or transmitted through the magazine to a radiation-receiving system lying in an indication circuit. An output signal dependent on the number of pulses reflected or transmitted, and indicative of the sample position in the magazine, is thus produced. This signal, in combination with a further signal identifying the magazine from sensing marks and/or formations on the magazine, from the sample recognition character. The process of the invention may be carried out in the device illustrated in Fig. 1, wherein magazines 2 containing samples are fed by clamping device 3 and transport device 4 to a scanning zone comprising flash-tube 8. The transport device is connected to a step counter 10. Light pulses transmitted by the magazine, are detected by radiation receivers 9 which are connected to indicator circuit 11, to which is also connected step counter 10. In operation, movement of a magazine by transport device 4 is recorded on step counter 10. In the scanning zone, such light pulses as are transmitted by the magazine, thus defining the sample position on the magazine, are recorded by photo diodes in radiation receivers 9. Signals from radiation receivers 9 and step counter 10 are fed to indicator circuit 11 which results in this circuit emitting a sample recognition character. The magazines are provided with light detectors 16 to facilitate the transmittance of light from scanning zone to radiation receiver. In Fig. 2 (not shown), these detectors take the form of recesses which pass through the magazine. In alternative arrangement, the detectors can take the form of glass fibre conductors or depressions clad with a reflecting layer.

Title: Marking device
IPC: B41F3/12
Filed: 1959-09-09
Abstract: 930,204. Warping yarns. SUCKER G.m.b.H. GEB. Sept. 9, 1959 [Oct. 17, 1958], No. 30778/59. Class 142 (1). [Also in Group XVI] A device for applying marks to travelling web material, e.g. warp thread bands, comprises measuring means for determining the interval between successive marking positions and including exchangeable gearing continuously driven from the material, a marking stamp mounted for rotational movement during which it momentarily contacts one surface of the material and means actuable in dependence upon a predetermined rotational movement of the gearing to rotate the marking stamp. As shown, marking stamps 23a, 23b are resiliently carried by leaf springs 230 mounted on rotatable discs. The discs are rotatable on the shaft of a friction wheel 25 which bears against the material 29 and is rotated thereby as the latter is fed through the machine. The discs carrying the stamps 23a, 23b can be coupled to the shaft for rotation therewith by a slipping friction clutch 26. The discs carry laterally projecting bolts 121a, 121b which are engaged by pawls 21a, 21b to restrain the discs against rotation. The pawls can be raised by electromagnets 20a, 20b so as to allow the discs to be rotated through the clutch 26, the stamps 23a, 23b being then inked by a roller 27 after which they make an impression on the material 29 as it passes over a counter pressure roller 24. The electromagnets are controlled by a measuring device which includes a roller (not shown) mounted on a shaft 6, Fig. 1, and running in contact with the material. The shaft 6 drives, through a chain and sprocket arrangement 7, 5, 8, a gear 9 which meshes with a second gear 10. The gear 10 through a chain drive 11 effects rotation of a pinion 13 meshing with a gear 14 with which are associated cams 14a, 14b having their high points spaced by 180 degrees. The cams actuate switches 15a, 15b in the circuits of the electromagnets 20a, 20b respectively. The gears 9, 10 are readily replaceable by gears of a different ratio and by this means the spacing of the marks made on the material by the stamps 23a, 23b can be regulated. A table showing the gears appropriate for different spacings is provided at 41. Relays are built in to the circuits of the electromagnets and deenergize the latter in time to prevent a second revolution of the stamps. The marking off of lengths of the material 29 may be effected by either or both of the stamps 23a, 23b, selection being by means of switches 42, 45, Fig. 1, and signal lamps 43, 44 indicate the moment of marking by each stamp. An electrically operated counter 47 controlled by the switches 15a, 15b is advanced one unit as each mark is made. A predetermined number of lengths may be set on the counter at 48 and after this number of lengths has been marked off the machine is automatically switched off or a signal is given. The pinion 13 can be temporarily uncoupled from the gear 10 to allow the position of the cams 15a, 15b to be registered with respect to the material before marking commences.

Title: Improvements relating to apparatus for stopping an electrically driven machine part in a pretermined position
IPC: D05B69/22
Filed: 1962-08-13
Abstract: 992, 275. Sewing machines. O. B. SCHWAB, [trading as FRANKL & KIRCHNER]. Aug. 13, 1962 [Aug. 23, 1961], No. 30888/62. Heading D1G. [Also in Division H2] To stop a series commutator motor 7 driving a sewing machine, treadle 1 is released so that starting resistance 4 is increased until the motor is de-energized. Contacts 5, 6, are engaged before the motor comes to a standstill and a control circuit comprising transformer 12, 13 is energized. A transistor 16 is conductive, provided that centrifugal switch 11 is closed, so that electromagnetic brake 10 is excited to apply the brake and relay 17 responds so that the motor remains disconnected from the line during the braking operation. When the motor reaches a low speed, the centrifugal switch is opened whereby control of transistor 16 is taken over by photo-transistor 18. If the transistor receives light from source 14 by way of reflector 21 on balance wheel 22, its resistance is reduced and transistor 16 remains conductive so that the motor continues to be braked and may come to a standstill. The setting of reflector 21 corresponds to the dead centre position of the sewing machine needle. If the machine overruns this position, the motor is re-connected and continues to operate until the reflector again throws light upon the photo-transistor element whereupon the brake is re-applied. The brake comprises armature 27 coupled to rotor shaft 26, the brake coil being associated with non-magnetic disc 30 having a friction surface. A magnetic disc 32 is fixed to the armature 27. When the motor is energized, the brake is released due to axial movement of the rotor. The centrifugal switch 11 comprises insulating disc 34 supporting spring elements 35, 36, to which are fastened carbon brushes 37, 38. The rotating part of the switch comprises insulating plate 41 having slip-rings 42, 43. Weights 44, 45, are interconnected by a strap and are adapted to engage members 47, 48, connected to the sliprings. At low speeds, one or both weights hang down to interrupt the current. The control components except the photo-transistor 18 and light source 14 are accommodated within the motor housing.
