Filed: 1962-09-11
Abstract: 1,013,404. Windscreen wipers. TRICO PRODUCTS CORPORATION. Sept. 11 1962 [Sept. 11, 1961], No. 34704/62. Heading A4F. The backing strip 15 of a windscreen wiper blade has intermediate its ends a widened portion having a notch 24 for receiving and preventing longitudinal movement of one of the claws 14 by which a yoke 12 is attached to the wiper blade. The slot 32 in the backing strip 15 has an enlargement 31 adjacent the notch to facilitate twisting of the strip 15 when it is desired to release the claw 14 from the notch 24. The wiper rubber 16 is rendered more flexible in its central portion by a notch 33 provided in its rear surface, and adjacent the notch 33 the flexibility of the strip 15 is increased by an enlargement 36 in its longitudinal slot 37. A cross-brace 34 adjacent the enlargement 36 restricts relative movement of the two side portions of the backing strip 15 during the wiping operation.

Title: Improvements in or relating to collecting mechanism for use in cigarette making machines
IPC: A24C5/32
Filed: 1937-12-15
Abstract: 504,652. Cigarette-making machines. RUAU, F. F., and MOLINS MACHINE CO., Ltd. Dec. 15, 1937, No. 34715. [Class 130] In mechanism for collecting cigarettes of the kind in which cigarettes severed from a continuous rod and spaced axially on a conveyer band are moved laterally from the band by a deflecting element, the cigarettes impinge against an abutment disposed at right-angles to the direction in which the cigarettes are moved axially, and rebound against a stop. As shown in the Figure, rotatable elements 9, 10 mounted on a spindle 11 deliver the cigarettes transversely from a conveyer belt 8 to a collector belt 13. Abutments 17, 19 against which the leading ends of alternate cigarettes impact, and stops 18, 20 against which the cigarettes rebound cause portions of tobacco projecting from the cigarettes to be moved towards the end faces of the cigarettes. The -abutment 19 and the stop 18 may be carried by a bar 16 adjustable laterally of the belt 13 or may be slidably mounted on a spindle disposed above the belt 13. To arrest any upward movement imparted to the cigarettes by the elements 9, 10 hinged guides 21 or hanging pieces of felt may be provided above the belt 13.

Title: Image-reproducing system for a television receiver
IPC: H04N5/57
Filed: 1963-09-03
Abstract: 1,008,118. Television; automatic gain control. HAZELTINE CORPORATION. Sept. 3, 1963 [Sept. 13, 1962], No. 34741/63. Headings H3X and H4F. Undesired variation in the level of the video signal which is reproduced as black in a cathodetube 26 (consequent upon variation of the potential applied to the second grid 29 as a result of the variation of the loading which is placed on the horizontal flyback generator 36 when the average scene brightness changes) is prevented by applying the potential on grid 29 to vary the potential at which a reference level in the video signal is stabilized. As illustrated, the blanking level in the signal is stabilized by an A.V.C. circuit 40 which is rendered operative during the back porch intervals by horizontal flyback pulses from winding 38 and which derives a control potential which is applied via winding 38 to the amplifiers in receiver 21. In accordance with the invention the potentional on grid 29 is also applied to the cathode bias circuit of a pentode 41 in the A.V.C. circuit 40 and varies the level at which the blanking level is stabilized so as to compensate for the variation in the characteristic of cathoderay tube 26. Only a fraction of the potential on grid 29 may be used by introducing a resistor 52a so as to form a voltage divider with a coupling resistor 52. Coupling network 24 between video amplifier 22 and tube 26 is constructed as described in Specification 1,008,010, so as to provide D.C. coupling for signals representing scenes of low average brightness and A.C. coupling for signals representing scenes of high average brightness. In a first modification, Fig. 5 (not shown), a triode replaces pentode 41. In a second modification, Fig. 6 (not shown), stage 40 also uses a triode but the control potential is derived from a modified cathode circuit and is applied to the grid of video amplifier 22. This last arrangement functions as a D.C. restoration circuit and it is necessary to A.C. couple the video signal to the input of amplifier 22 at a point prior to the application of the control potential from circuit 40.

Abstract: 416,317. Monogrammic signs. ZOUCKERMANN, A., 17, Avenue Carnot, Paris. Dec. 9, 1932, No. 34982. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 12, 1933]. [Class 118 (ii).] The individual members of a field of elements or lamps constituting a monogrammic sign are displayed by the action of an electromagnet 2 attracting a core 16 so as to admit compressed air for holding the element in the display position or in the case where the display element is a lamp, for maintaining it illuminated. Each display element may comprise reflecting surfaces 24 adapted to be projected between partitions 25 into the display position by a diaphragm or piston 7 against the action of a spring 22<a>, the compressed air for actuating the diaphragm being admitted when the electromagnet 2 is energized and a disc 10 attached to the core 16 uncovers a tube 19. The admitted air acting on the disc 10 forces it against flanges 8, 9 and passes by way of apertures 15, 17, 5 to the diaphragm 7. A spring 18 restores the disc 10 against the tube 19 when the compressed air supply is momentarily stopped. A plurality of these elements are plugged into a panel 21. In a modification the core is directly connected to the plate 23 supporting the surfaces 24. In another modification, Fig. 7, the moving disc 10 closes contacts 31, 32 for the display lamp 30<a>. Where moving display surfaces are used, the movement may be one of oscillation or rotation. The coil may be the movable member, the armature being held fixed. Fig. 10 shows a spring 36<a> securing a lamp element 33<a> and its reflector 34<a> to a panel 35<a>. Reflectors 44, Fig. 13, may be used for a panel located above the spectators, the perforations 45, 41 in the reflectors and the common return strip 40 having a screw edge for securing on the lamp cap 42.
