Title: Regulating apparatus
IPC: G05B11/01
Filed: 1954-05-04
Abstract: 757,442. Electric - control systems. GUGELBERG A. VON, [trading as ELESTA ELEKTRONISCHE STEUERAPPARATE, DR. A. VON GUGELBERG]. May 4, 1954 [Dec. 7, 1953], No. 13001/54. Class 40(1) [Also in Group XL(b)] In a control apparatus in which current through a photocell, ionisation chamber, or a resistance dependent on light or other radiation, temperature, pressure or other physical variable controls a pair of gas discharge tubes each with a cathode, anode, and starter electrode, the latter are connected through the photocell, &c., and are each connected through high resistance elements to a bias supply. The discharge circuits containing the anode and cathode of each tube each include a series connected resistor and are fed from a common D.C. source and means are provided, including an electric coupling element for coupling the discharge circuits which on firing of one of the tubes always extinguish the other ignited one. In the twilight switch (Fig. 2), for operating road, office, shop-window, &c., lamps in response to changes in ambient illumination two cold cathode discharge tubes 2, 3 with trigger electrodes between which a photocell 1 is connected are supplied with stabilized voltage via rectifier 19, smoothing capacitor 20 and stabilizer tubes 22, 23, bias for the triggers being tapped off the stabilizer voltage through high resistors 4, 5. When, for instance, tube 3 is conducting, i.e. with high illumination of photocell 1 its trigger potential is determined by the discharge whereas the trigger potential of tube 2 controlled under fixed illumination conditions by the value of bias tapped off potentiometer 6 is set so that tube 2 is extinguished. When the level of light falls below a preset value the trigger voltage of 2 becomes sufficient to ignite it. The consequent increased voltage across common resistor 12 together with the voltage across capacitor 11 which is temporarily maintained causes a sharp fall in potential across tube 3 thereby extinguishing it. Moreover, when the discharge ceases the trigger potential, now controlled by the bias from potentiometer 7 is insufficient to re-ignite it. Discharge through tube 2 is maintained until the illumination rises above a level determined by the variable bias from potentiometer 7 when tube 3 is re-ignited. The resulting increased voltage across resistor 12 and the stored voltage on capacitor 9 causes tube 2 to be extinguished. While tube 2 is conducting the load circuit 16 containing the lamps is completed by the contacts of relay 18. Capacitors 13, 14 prevent momentary changes in illumination from flashing the lights. In an alternative arrangement the relay winding 18 is replaced by a resistor and the potential available at the anode of 3 or cathode of 2 is used to control thyratrons which control the lighting circuits. A similar circuit, Fig. 1, not shown, may also be used for control in response to changes of, e.g. pressure, temperature and intensity of radiation other than light by substituting for the photocell elements the resistance of which is a function of these variables.

Abstract: 1,208,977. Conveying tobacco. HAUNIWERKE KORBER & CO. K.G. 19 March, 1968 [22 July, 1967], No. 13196/68. Headings B8A and B8S. Tobacco 13 is conveyed rightwards in the vibrating trough 7 and falls through aperture 11 into hopper 12, the fall of the tobacco being controlled by belt 1. Belt 1 is fixed at B to trough 7 and moves as a unit, being mounted on the end of piston 9 of fluid cylinder 8. When the aperture 11 is to be closed fluid cylinder 8 is energized to move belt 1 to the right. Since the belt is fixed at B to trough 7 the belt partakes of two movements a rightward movement and a circular movement about the rollers 2 and 3. The movement to the right of the belt 1 is quicker than the movement of the tabacco 13 so that the belt closes the aperture before the tobacco arrives at the end 16 of the aperture. In this way the position 16 of the trough is kept free from tobacco. The vibrating trough may be replaced by a feed duct.

Title: Apparatus for and method of inspecting of members or mechanical parts
IPC: G02B21/00
Filed: 1956-05-02
Abstract: 804,654. Electromagnets. RAZDOW, A. May 2, 1956, No. 13477/56. Class 35. [Also in Groups II, XIX, XX and XXII] An electromagnetic system for moving an upper row of armatures 51, Fig. 11, and a lower row of armatures 52 against a turbine blade, the dimensions of which are to be checked (see Group XIX), comprises two solenoids 95 and 96 energized through a double pole, two-way, switch 97. When the switch is in the left-hand position a motor 99 rotates and turns a contact 100 so that it passes over a number of terminals 102 connected to the forwardly disposed solenoid 95. The resulting electrical impulses to the solenoid 95 brings about a slow stepwise advancement of the armatures 51 and 52. When the switch 97 is in the right-hand position, only the solenoid 96 is energized and causes a fast return of the armatures 51 and 52. In a modified construction there may be a second set of terminals 103 (not shown) between the terminals 102 and every time the contact 100 passes over a terminal 103 the solenoid 95 is arranged to be short-circuited to cause a braking action on the armatures 51 and 52. In a further arrangement, Fig. 13, a series of solenoids 104 to 109 are used. When a double-pole switch 972 is moved to the left, a motor 99<SP>2</SP> causes an arm 100<SP>2</SP> to rotate and energize in turn the solenoids 108, 107, 106 and 105, the solenoid 104 being continually in circuit during this period. This causes a forward step-by-step motion of the armatures. When the double-pole switch 97<SP>2</SP> is moved to the right the solenoid 104 is cut out and the arm 100<SP>2</SP> rotates in the opposite direction to energize in turn the solenoids 105, 106, 107 and 108, the solenoid 109 being continually in circuit during this period. This causes a reversed step-by-step motion of the armatures. Reference has been directed by the Comptroller to Specification 786,213, [Group XIX].

Abstract: 923,186. Copying documents. A. B. SMITH. April 21, 1960 [April 21, 1959], No. 13498/59. Class 100 (2). A rotary duplicating machine, especially for tabulating data from record sheets, comprises a rotary cylinder 10 with means 51, e.g. a clip, for mounting a copy sheet 50 upon the periphery thereof, driving means for the cylinder, a roller, not shown, in pressure contact with the cylinder, a feed platform 16 from which successive master slips 45 bearing the data to be tabulated in mirror-script can be advanced to the nip between the cylinder 10 and roller at like predetermined positions of the driving means, and a connection between the cylinder and driving means whereby the leading edge of the copy sheet 50 is automatically brought to the nip at a progressively earlier stage in each revolution of the driving means. The copy sheet 50 is moistened by a roller 22 carried by brackets 23 and engaging a spirit-holding pad 21. The brackets 23 are moved towards the cylinder 10 by a rack 32, Fig. 2, engaging a gear 33 on a shaft carrying a pinion 36 engaging a toothed sector 37 of a disc 38 driven by a gear 12 on a shaft 11 driven by a handle 15. The cylinder 10 is driven by the gear 12 through a gear 13 on the cylinder shaft 9, the ratio of the gears 12, 13 being 61 to 60 such that check means, not shown, operating on the shaft 11 stop the cylinder 10 in an angularly advanced position with respect to the nip 17 at each revolution. In these circumstances, successive fed master slips 45 carrying items 47 in mirror-script are reproduced line by line in tabular manner on the copy sheet 50. In a modification, the shaft 9 (Fig. 4, not shown) carries a rotatable sleeve 52 secured to the cylinder and carrying a ratchet wheel 53 and disc 54. The disc drives the wheel 53 through a pawl 55 and a second pawl 59 moved axially against a spring 61 by a cam surface 62 on an arm 63 to produce a superimposed additional angular movement of the cylinder just before the leading edge of a master slip enters the nip. In a further modification, Fig. 5 (not shown), the superimposed additional angular movement is produced by differential gearing. Alternatively, the gears 12 and 13 may be coupled by infinitely variable gearing to permit variation in the spacing of items reproduced on the copy sheet 50.
