Title: Method and apparatus for printing
IPC: B41M1/12
Filed: 1964-11-13
Abstract: 1,094,063. Electrostatic printing apparatus. OWENS-ILLINOIS Inc. Nov. 13, 1964 [Nov. 13, 1963; Aug. 31, 1964], No. 46254/64. Heading B6C. A screen-printing apparatus for electrically printing with powder particles upon the lower surface 12 of a heated glass article 10 comprises a suitably imaged wire mesh stencil 18, or plate 16 of metallic or electrically conductive material supporting an evenly spread pile of powder particles 14 and electrical apparatus whereby potential may be simultaneously applied from an A.C. or a D.C. source to the stencil and the article to create electric fields which attract and accelerate particles from the pile to pass through the stencil aperture for deposition upon the surface 12. In a modification the stencil is electrically non-conductive the potential being applied across the plate and the article. If the surface 12 and stencil 18 are vertical, piles of powder are supported upon a vertical plate 16. In yet a further embodiment, particle transfer from a supply of glass frit powder 110, Fig. 5, is accomplished by applying potentials to a plate 112, a screen 114 and an article 116 a relatively high voltage being applied across the space between the plate 112 and the screen 114 while the article surface 116 is held at a relatively low voltage with respect to the screen, the potentials at the plate and the article being of opposite polarity. The high voltage potential may emanate from the indicated pulse circuit, each potential pulse being for approximately 25 to 300 milliseconds. In a modification of the Fig. 5 apparatus a non-conductive screen is placed between the screen 114 and the article 116 whilst a common high voltage source is connected across article 116, screen 114 and plate 112 by variable voltage dividing resistances which may be adjusted as desired to proportion the voltage drop between the plate and screen and between the screen and article.

Title: Controlled insertion force receptacle for flat circuit bearing elements
IPC: H01R12/88
Filed: 1971-10-08
Abstract: 1369852 Edge connectors BUNKER RAMO CORP 8 Oct 1971 [18 Jan 1971] 47023/71 Heading H2E An edge connector has one or more slots to receive boards 40. As shown, each of two slots 12A, 12B contains contact fingers 34, which are positioned so as to apply a controlled low or zero pressure to a board 40 while it is being inserted. Each finger has a bottom portion 36 for connection to inner or other devices, a middle portion sloping toward the centre of the slot, and a top portion sloping away. When the board is in position a cam 26A, 26B of elliptical cross-section is rotated, with the aid of a slotted knob (32A, 32B, Fig. 2, not shown) at one or each end, from the position shown for cam 26B to that shown for cam 26A. The cam forces a slide 16A, 16B upwards. Projecting fingers 18A, 18B on the slide bear on the ends of the contact fingers 34, causing the contact fingers to move inwards to place increased pressure on the board. Because the contact fingers are resilient each contact area on the board experiences substantially the same pressure, despite curvature of the board or variations in its thickness. When the cam is in the position of cam 26B, the fingers 18 are held down by pressure from the contacts. In the preferred embodiment in which the boards are inserted from the end, if the cam is in the position of cam 26A when no board is in position subsequent insertion of a board is prevented by a projection (33) on the knob (32A). The arms 26 may be of metal, so as to withstand the applied torque while being of small cross-section. The connector body comprises a frame 10 and a baseplate 20.

Abstract: 1517704 Barrel lock NORMAN LOCK CO 21 Nov 1975 47912/75 Heading E2A A barrel lock comprises a lock cylinder 14, rotatably mounted in casing 12, into which insertion of key 19 results in moving a number of balls 40 via pins 26 into a straight line chain so moving actuating lever 42 into engagement with slot 68 in shaft 64 which is connected via member 70 to a locking bolt. Before insertion of key 19 (Fig. 3) in cylinder 14 the cylinder is free to rotate in casing 12 but when the key is correctly inserted (Fig. 4) with lever 42 engaging slot 68 rotation of the key and hence cylinder results in rotation of shaft 64 and unlocking of bolt connected thereto. The key 19 in the form of a U-section moves two staggered rows of pins 26 in bores 22, 24, and the balls 40 are alternately offset on the pins to form a single row of balls (Fig. 7). The balls 40 are movable to a limited extent laterally relative to pins 26 in bores 22, 24 so that the longitudinal lock-opening force exerted by the balls cannot be felt through the pins 26. In a further embodiment (not shown) the lever 42 may engage a slot in the casing 12 to prevent rotation of the cylinder when the key is absent and be disengaged when the key is inserted, the cylinder being connected to a locking bolt in a conventional manner.
