Title: Improvements in windscreen wipers
Inventor: SMITHERS PHILLIP GEOFFREY KENT
IPC: B60S1/38
Filed: 1958-04-01
Abstract: 913,717. Wind-screen wipers. TRICOFOLBERTH Ltd. April 1, 1959 [April 1, 1958], No. 10519/58. Class 138 (1). A wind-screen wiper blade, made of rubber or similar flexible material, is substantially of cruciform shape in cross-section and comprises a central upper arm, Fig. 2, formed with a head 12 and neck 14, lateral arms 16 and 18 formed with wiping lips 22 and 24 respectively, and a central lower arm 20 formed with a rounded lower edge which forms a fulcrum for rocking movement of the blade as shown in Fig. 3. The arm 20 may alternatively be formed with a wiping lip. Holes or slots 26, 28, Fig. 4, extend obliquely through the blade and connect the recesses between opposite pairs of arms. The head 12 engages a backing strip comprising side portions 30, 32, joined at intervals by integral bridges 34. The backing strip is coupled to the usual actuating arm by primary and secondary yokes which may be V-shaped in cross-section. The perpendicular bisectors of lines bridging the recesses between the arms 18 and 20 and the arms 16 and 20 preferably intersect at the neck 14. In use, the blade rocks through approximately 60 degrees as it swings to and fro to cause the arms 16 and 18 to engage the screen alternately, but if there is an airflow of substantial strength over the screen, the blade will rock in a direction opposite to that of the airflow irrespective of the direction of movement of the blade. The flow of air through the holes or slots which are parallel to the screen will tend to equalize the pressure in the connected recesses and thus prevent the blade being lifted from the screen. Fig. 3 shows the attitude of the blade when it is moving in the direction 36 against an airflow in the direction 38, the lip 22 being bent inwardly. When the blade moves in the opposite direction, the frictional drag tends to rock the blade to bring the lip 24 into engagement with the screen, but the airflow maintains it in the attitude shown in Fig. 3, the lip 22 being bent outwardly as shown in Fig. 3A.

Abstract: 885,310. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 27, 1958 [April 3, 1957], No. 10832/57. Class 39(1) In an electron discharge device of the kind comprising a photo-emissive cathode 3 on to which an optical image can be projected and a target 6 on to which the photo-electrons from the cathode can be projected so as to charge the target negatively, the other side of the target is provided with a mosaic of photoemissive elements so that it can be scanned by a light beam to restore the elements of the target to an equilibrium potential and the target is arranged to be substantially opaque to light so that light from the scanning beam is prevented from passing through to the photo-cathode. The target preferably comprises a thin sheet of partially conducting glass, the photo-sensitive elements, which are thick enough to be opaque to light, being formed by depositing silver or evaporating a bismuthsilver alloy through the interstices of a mesh and thereafter oxidising the elements and rendering them photo-emissive by the application of caesium. Alternatively antimony may be deposited through a mesh and then caesiated. Prior to depositing the mosaic elements the surface of the glass sheet may be provided with a layer of aluminium which is heated or oxidised or both to prevent charge leakage over its surface and which renders the target opaque independently of the mosaic elements. The glass sheet may be coloured so as to absorb light from the scanning beam, or at least that portion of it which lies within the spectral response curve of the photo-emissive cathode 3. Also, the side of the target facing the cathode 3 may be provided with non-photosensitive mosaic elements which may be formed by evaporating aluminium through a suitable stencil. Alternatively the target may comprise a multiplicity of conducting elements projecting through an insulating sheet. The spectral emission of the luminescent screen 10 in the tube 9 may be chosen to match the sensitivity curve of the emissive elements of the target but not that of the cathode 3. The photo-electrons released by the scanning beam are preferably focused and directed into an electron multiplier 17 by means of electrodes 14, 15 and 16, or electrode 16 may be replaced by a metal mesh at a suitable negative potential, or a small electrode forming the first stage of the electron mulitplier.
