Title: Improvements in or relating to windscreen wipers
IPC: B60S1/40
Filed: 1948-11-24
Abstract: 660,286. Windscreen cleaners. O'SHEI, W. E. Nov. 24, 1949 [Nov. 24, 1948], No. 30575/48. Class 138 (i) [Also in Group XXV] A connector for a windscreen wiper blade and arm comprises a connector body adapted to be carried by one of two parts respectively constituted by the arm and blade, and a member projecting from the other part, the projecting member being received and retained in a socket in the connector extending substantially at right angles to the windscreen when the blade rests thereon by a spring pressed member incorporated in the connector and adapted for movement substantially parallel to the windscreen. As shown in Fig. 1 a die-cast connector 14 is pivotally connected to a wiper blade backing 5, by a transverse pin 6, so that the blade is enabled to engage with the windscreen surface throughout its entire length. Apertures in the blade backing 5, through which the pin 6 passes, are large enough to enable the blade to rock on the pin within a U-shaped channel 17, formed in the connector, when the blade reverses its direction of movement over the windscreen, and thereby adopt a trailing position. The connector 14 is provided with a rectangular aperture or socket 7 to receive the inturned projection 12 on the end of a metal strip wiper arm 3. The projection 12 is provided with an aperture 20 which is interlocked with a protuberance 21 on a spring-pressed plunger 9 housed within the connector. The connector and blade may be rigidly secured together and the rocking action of the blade to a trailing position may then be facilitated by providing clearance between the sides of the projection 12 and the side walls of the aperture 7, so that the connector 14 can rock relative to the projection. Also the projection may be carried by the blade and the connector may be carried by the arm.

Title: System for signalling breakdowns in the filaments of thermionic valves
IPC: H03F1/54
Filed: 1933-11-03
Abstract: 407,645. Valve circuits. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES, 26, Rue de la Pepiniere, Paris. Nov. 3, 1933, No. 30627. Convention date, Nov. 14, 1932. [Class 40 (v).] Relates to a system for signalling breakdowns in valve filaments in which the filaments 1, 1<1> form arms of Wheatstone bridges constituted by resistances 4, 4<1>, 5, 6, the equipotential diagonals containing signal lamps 2, 2<1>. According to the invention, the equipotential diagonals have a common relay coil 3, and means, such as rectifiers 7, 7<1>, 7<11> in the diagonals, to prevent out of balance currents due to a filament break in one arm flowing through other filament circuits. In a modification, the balancing resistances 4, 41 are replaced by other valve filaments and two relay coils 3 are used, each fed from a separate set of diagonals, the rectifiers in one set being reversely poled with respect to those of the other set (Fig. 4, not shown).

Title: Camera shutter mechanism
IPC: G03B9/18
Filed: 1976-07-22
Abstract: 1534081 Camera shutter SEIKO KOKI KK 22 July 1976 [23 July 1975(2)] 30627/76 Heading G2A A shutter has a drive member 9 coupled by a connecting member 10 to an actuator 4 for moving opening blades 3 to initiate an exposure; closing blades 6 movable to terminate the exposure; means 11a for releasing the connecting member 10 just before, at or just after exposure termination; and means 4f for thereafter moving the actuator 4 to return the opening blades 3 to the closed position. Since the opening blades are returned, the light occluding properties of the closing blades is not as important and they may therefore be smaller and of light material e.g. plastics. Also rebound of the closing blades no longer matters. To make an exposure, spring 9f rotates drive member 9 clockwise. Connecting member 10 is carried by member 9 and, by engaging a projection 4c, causes actuator 4 to rotate clockwise and move opening blades 3 to their open position. A second drive-connector-actuator mechanism 11, 12, 7 then moves closing blades 6 to their closed position. As the blades 6 close, an arm 11a on the second drive member 11 rotates the first connecting member 10 anti-clockwise and this allows a spring 4f to rotate the first actuator 4 ACW to move the opening blades 3 to a closed position. Preferably an arm 4c on the first actuator 4 then initiates movement of the closing blades 6 to an open position. Alternatives (not shown). In Figs. 4 and 7 to 9, the first connecting member 10 is released by an arm (207d, 507d) on the second actuating member. In Fig. 5, the first connecting member 10 is released by a member (13) operating in conjunction with the return of a reflex mirror. In Fig. 6, the shutter has three opening blades and four closing blades. In Fig. 10, the spring 4f is replaced by a spring (61 Of) acting between the first actuating and connecting members 4 and 10.
