Title: Improvements in stoppers for bottles, jars and the like
IPC: B65D51/24
Filed: 1959-06-05
Abstract: 918,985. Stoppers. MARCEL, H. June 5, 1959 [June 13, 1958], No. 19339/59. Class 125(3).  A stopper head 1 of rigid plastics material has an annular groove 1c for the attachment of a cover 2 with a transparent end wall, made e.g. of a plastics material by injection moulding, the cover 2 enclosing a paper disc 3 carrying advertising material. A projection 2b on the cover 2 acts as an anchor for the cover in the groove 1c and the inner wall of the head 1 has teeth 1b for anchoring the head on a stopper body (not shown) of plastics material or cork. In a modification, Fig. 7, the head 1 is moulded integrally with a stopper body of polythene, the body being hollow and open at its lower end. This modification may be varied by the addition of ribs on the internal surface of the flange of the cover 2, Fig. 8 (not shown). The stopper may have a polygonal head; or again, the upper face of the head may be convex. Specification 729,291 is referred to.

Abstract: 478,250. Controlling motor vehicles. BOSCH AKT.-GES., R. July 14, 1936, No. 19504. Convention date, Aug. 23, 1935. [Class 79 (v)] [Also in Groups XXVII and XXXV] In a control mechanism for motor-vehicle engines and engine starters, the starter 15 is put into operation by a pedal 2 acting through a connecting element 4 ; when the engine starts, the element is moved by engine suction into a position in which it enables the pedal 2 to control a clutch or other operable device associated with the engine. As shown, the engine member to be controlled is the throttle valve 16. The connecting element 4 is pivoted on a sleeve 3 on the rock shaft 1 on which the pedal 2 is mounted, and is normally held by a. spring 11 in position to engage a rod 12 bearing on a lever 14. On depression of the pedal 2, the lever 14 shifts the starter pinion 17 into mesh with the engine gear 18 and closes the switch 19 of the starting motor. When the engine starts, movement of the element 4 into position to actuate the rod 13 and the throttle 16 is effected by engine suction acting on a piston in the cylinder 7, the piston being connected to the element 4 by a rod 10. In modifications, (a) the element 4 slides on splines on the shaft 2, and a flange on the hub of the element is engaged by a piston-rod corresponding to 10, or by a fork on the piston-rod ; (b) the element 4 is pivoted as in Fig. 1 and is engaged by a shoe on the piston-rod 10.

A textile fabric in rope form is moved in substantially helical loops through liquid in a tank 12, over a rotating spiral guide 22, an idler reel 36 and a driven main reel 20. The leading end 32 of the fabric is attached to a swivel finger 26a of a conveyor chain 26 located at one end of the reels and spiral guide. The leading end of each new loop as it is formed is supported away from the idler reel 36 by means of a guide 40 comprising a horizontal support 42, substantially vertical rods 44 and 46, upwardly inclined rods 50 and 52 and cross rods 48 and 54. As the spiral guide rotates the loop is pulled off the guide which is then ready to receive the next loop. The main reel, spiral guide and conveyor chain may be driven by a common motor (Fig. 12, not shown) to which the main reel, determining the speed of the loops, is directly connected; the conveyor chain, whose speed determines the size of the loops, is connected through an infinitely variable gear box; and the spiral guide whose speed determines the spacing of the loops, is connected through a selectively variable transmission on the output end of the gear box. The shaft of the spiral guide may be connected to a drive shaft from the transmission, by means of interlocking end plates (Figs. 5-10, not shown). The fabric may be dyed, bleached, or scoured.

Class 39(1) A measuring chamber for X-ray radiation comprising a gas filled ionization space provided between two parallel walls of insulating material. which walls, on their opposing surfaces, are each coated with a conductive layer constituting an electrode, and an entrance window through which the X-ray radiation may enter the ionization space, which window is constituted by part of one of said walls, the effective atomic number of the conductive layers being lower than that of the gas filling, is characterized in that the electrodes are spaced apart by about 1 mm. and the entrance window has such thickness that the sensitivity of the measuring chamber is substantially independent of the wavelength of the X-rays at least throughout a range of wavelengths having a halving thickness between 0.04 mm. and 1.5 mm. Al. The so-called " flat " measuring chamber shown comprises an inner case 1 and an outer case 2 separated by a narrow intermediate space 3 filled with a conductive layer 4 of carbon, for example graphite, enclosing a conductor 5.

Abstract: 1533441 Angular displacement transducers XEROX CORP 14 May 1976 [19 May 1975]  19909/76 Heading G1N [Also in Division G3] Apparatus for measuring the eccentricity error in one element of an inductive angular displacement transducer assisting of two discs each carrying a circular zig-zag pattern of conductive strips comprises a master disc 10, Fig. 1 with the conductive pattern 27, mounted for rotation by a motor 12, facing the test disc element 13 which is energized with A.C. from an RF signal generator 15, the induced voltage in disc 10 being analyzed to determine the x and y coordinate of eccentricity of disc 13. These component signals are fed to motors 21, 22 to reposition disc 13 with its eccentricity removed, and a drill 26 bore a hole in the disc at its electrical centre. To obtain analyzable error signals the master disc 10 is itself mounted for rotation about an eccentric axis 11. The voltage induced in the series connected conductive strips 27 on disc 10 consists of an RF carrier frequency voltage, amplitude modulated by each pitch of the zig-zag pattern on the discs and further amplitude modulated with one cycle per revolution of disc 10 by the eccentricity of disc 13. This voltage is fed via rotary transformer 31 to a unit 17 comprising an eccentricity detector 71 (Fig. 2) and resolver 72. The detector 71 removes the RF carrier at demodulator 74 and the LF carrier by filter 78, 79 leaving the eccentricity signal. The resolver 72 sampler the amplitude of the eccentricity signal at four 90 degrees displaced instants in the revolution cycle, the first being coincident with a reference mark 96 on rotor 10. These four amplitudes are combined in pairs and fed to x and y eccentricity indicators 23, 24 and servomotors 21, 22 which move the test disc 13 to the position of no eccentricity.
