Abstract: 1290190 Cathode-ray display tube ISE ELECTRONICS CORP 10 Oct 1969 [12 Oct 1968] 49867/69 Heading H1D A cathode-ray tube displaying characters (including letters, numerals, patterns or symbols) includes character forming means 7 between the cathode and the focusing and deflecting means 3, 4, the character means including a perforated insulating substrate, and a plurality of perforated electrode elements arranged each side of the substrate to form a matrix, whereby a positive field may be created at selected cross-over points by energization of appropriate electrodes to permit electron passage corresponding to the desired character. The remaining electrodes may be at negative potential. The electrodes may be in rows and columns and shaped as in Figs. 4 and 6 (not shown). Grid 6 uniformly disperses emitted electrons and insulating plate (9) (Fig. 7, not shown) of the matrix may be mica or ceramic. The electrodes may be individually secured to the substrate or electroconductive films may be provided and then etched. All electrodes may be at a potential to allow electron passage. The position of the character displayed may be varied by the deflection system and a number of characters may be simultaneously displayed. Different combinations of points may be cyclically displayed to produce an apparently permanent display of different characters.

Abstract: 1296556 Latches AISIN SEIKI CO Ltd 13 Feb 1970 [13 Feb 1969 21 Feb 1969] 7137/70 Heading E2A A door latch member comprises a recessed base member 10 in which recess 15 a latch member 12 rotates, the recess and the latch member having arcuate portions of the same curvature and the latch member being engageable by a detent 17 pivotally mounted on the base member. The base member is made of plastics and in use is screwed to a door plate on the door. The latch member is sector shaped and has a central recess for rotatably engaging a pin 13 integral with the base member. The outer periphery of the latch member engages the edge of the recess. The latch member is urged to inoperative position by a spring 20 in a groove on the base member and anchored at one end to a pin 21 in the latch member. The detent head is stepped and rotates in a part circular recess in the base member and a portion of smaller diameter rotates in a hole in the base member and the free end is connected to a lever 30. The lever is urged by a spring to hold the latch member either in the fully latching position with the detent head contacting a surface 12e on the latch member or in the safety latching position with the detent head engaging a surface 12d of the latch member. During closing movement of the door a U shaped striker member 29 enters a recess 33 in the base member and a recess 24 in the latch member thereby turning the latch member to safety latching position and then to fully latching position. The striker member 29 engages a block 34 sliding on a rod in an enlargement of the recess 33, and moves the block against spring pressure as shown in Figure 3, the striker member being wedged between the block and the end of the recess 24. In a modification the pin 13 has a rotatable metal bushing and the latch member has a resilient bushing engaging over the metal bushing for pivotally mounting the latch member so that a small gap is present between the periphery of the latch member and the wall of the recess.

Coagulant may be injected into the water at 13 just before filtering, which permits a relatively high filtering flow. Periodically valves 12 and 14 are closed and the bed 8 cleaned by reverse flow of water from valve 15 to outlet 16, effecting up to 50% expansion of the bed. The volume of backwash water used in cleaning is only 1/2 to 2 times that of bed 8, the retained solids being largely flushed into the space above the bed, from which they are progressively displaced in subsequent backwashing operations. Valve 11 remains open to maintain a small raw liquid input during backwashing, and valve 19 is opened for a short time to discharge the turbid first filtrate after backwashing. Times and bed dimensions are exemplified.

The welding and severing operations may be carried out simultaneously. The welding may be effected by resistance welding or by dielectric welding. The flexible layer may be pressed towards the rigid layer along the line of the required recess, thus compressing the padded layer during welding so that, on completion of the welding, the welded portion of the flexible layer is spaced toward the rigid layer from the remainder of the flexible layer. An apparatus for use in the method comprises a dielectric welding electrode 16 having an elongated working surface 17 for encircling the required recess to be cut in the composite panel and a cutter 18 having a cutting edge 20 extending along the inner periphery of the electrode for severing the flexible and padding layers around the inner periphery of the weld line, the cutting edge of the cutter projecting beyond the working surface of the electrode. In operation, the apparatus 14 engages the flexible layer 13 of the panel and the opposite face of the panel is engaged by a further electrode (not shown) having a working surface corresponding in contour to the surface 17.
