Title: Improvements in or relating to windows
IPC: B60J1/00
Filed: 1947-04-18

Patent GB-1071985-A (GB)
Title: Improvements in or relating to impulse delay arrangements
IPC: H03K3/42
Filed: 1965-03-12
Abstract: 1,071,985. Automatic controls for packaging machines. A. SCHMERMUND. Feb. 16, 1966 [March 12, 1965], No. 10481/65. Heading B8C. [Also in Division H3] Electric impulses, fed to terminals 12, 13 of an impulse delay arrangement as a result of a fault developing in a cigarette-packaging machine, eventually cause an electric circuit connected to output terminals 16, 17 to be closed, thereby exerting a control effect on the machine, e.g. to eject an imperfect block or packet. A shaft 2 of the machine rotates carrying a cam 2 against which a plunger 3 is spring- urged. A switch 4, spring-urged against the plunger 3, has contacts 5, 6 which connect a terminal 7 alternately to conductors 8, 9. Terminals 7, 12 are connected to a D.C. supply, the terminal 12 being connected to a further conductor 11. The contacts of relays A-Z are initially open, the contact al of relay A being closed when an impulse is fed to terminals 12, 13. The relay B, which is thereby connected to the conductor 8, is energized when contact 5 of the switch 4 closes. Contacts b1 and b2 of the relay B are then closed; contact b1 connects relay C, while contact b2 holds relay B when relay A is de-energized after the impulse ceases. The opening of contact al of relay A is delayed by means of a resistor 14 and capacitor 15. Relay C is energized through conductors 9, 11 when the contact 6 of switch 4 closes. The sequence continues until the circuit connected to terminals 16, 17 is finally closed. A next impulse may be applied to the terminals 12, 13 when the contact 5 of switch 4 is open and before the relay Z has responded to the first impulse, thereby a number of impulses may travel simultaneously through the chain of relays. Instead of feeding impulses to terminals 12, 13, they may be fed direct to any one of the relays, e.g. relay D as shown, thereby shortening the delay effect. The control circuit may be connected to a third contact of any one of the relays, e.g. relay J as shown, instead of to the terminals 16, 17. Photo-electric relays (see Division H3) (as at A), Fig. 2, each comprising two electric lamps (al, a2) may be used with a light-sensitive resistor (a3) in a light-tight chamber (a4). Alternatively, each relay A-Z may comprise an electronic relay, e.g. a coldcathode tube, or it may comprise a transistor. The electromagnetic relays may be microrelays. The cam 1 may be replaced by an electric synchronizing arrangement.

Abstract: 890,766. Gymnastic apparatus. SPENCER, HEATH & GEORGE Ltd., and BATES, H. W. Jan. 6, 1961 [March 24, 1960], No. 10537/60. Class 132(1)  Gymnastic apparatus consisting of a boom which comprises one or more horizontal beams mounted for adjustment in a vertical plane comprises a supporting plate 14 and a pivotal attachment such as a stud 13 between the end of the beam 11 and the supporting plate by means of which the beam 11 can be supported and pivoted about its longitudinal axis in relation to the supporting plate, the supporting plate carrying or being formed with a projecting portion which serves to support the end of the beam in the event that the pivotal attachment between the beam and the supporting plate fails. The end of the beam 11 has a U-shaped plate 12 fitting in the plate 14. The beam pivots on the stud 13 secured to the plate 14. A suspension wire 15 passes through an aperture in a bent part of the plate 14 and round a stud 18 removably fitted in the bent part. The end of the wire is welded to the wire to form a loop which a sleeve 19 covers. The sleeve cannot pass through the aperture so the plate 14 rests on the sleeve in the event of the pivot stud breaking and the beam rests on the lower part of the plate 14. A pin 17 secures the plate 14 and beam 11. To prevent inadvertent separation of the upright guide members for the beam, each end of the beam has a downward extension cooperating with a pin 20 connected to an upright member.

The propeller rotates on ball bearings on a cylindro-conical column supported by the car, and the frictional torque is counteracted by arranging an adjustable rudder 25 in the wash of the propelling units 23, 24. Land wheels 12, 13, 14, 15 are arranged on spring undercarriages beneath the car.

Abstract: 376,366. Light current relays and protective cut-out arrangements. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Burton, E. T.; 97, Cypress Street, Millburn, New Jersey, U.S.A.) April 11, 1931, No. 10715. Convention date, April 11, 1930. [Class 38 (v).] In an electric circuitbreaking arrangement for the protection of electrical apparatus, a contact-making relay of the string galvanometer type is employed which has a fine aluminium wire 17, Fig. 1, stretched between fixed and adjustable frets 21, 22 so as to pass through an air gap 15 of a U-shaped permanent magnet 13 provided with a keeper 14, the wire being embraced at an intermediate point by an adjustable forked fixed contact 26. Thus when the deflection of the wire due to the current therethrough is sufficiently great the wire engages one of the tines of the forked contact, each of which is formed with a knifeedge contacting surface. The fork may be adjusted by a screw 28 to vary the value of current at which contact mav occur. The upper resilient fret 22 over which the wire passes is arranged against a fixed scale 25 in order that a wire may be replaced without a fresh calibration. The relay is employed as a protective device in the circuit of an oscillograph, telegraph, or other sensitive instrument in the manner shown in Fig. 2, the wire on making contact at 26 connecting a battery 30 across its lower portion so that a comparatively heavy current flows and fuses the wire at the point of contact 26 so breaking the circuit through the instrument &c. Alternatively, Fig. 3 (not shown), a charged condenser may provide the fusing current. A switch 31 may connect a telephone receiver in series with the wire across the battery for calibration purposes.
