Title: A shape gauging device or feeler gauge
IPC: B25D5/02
Filed: 1956-05-29
Abstract: 788,281. Shape gauging devices. DECKEL, H., and DECKEL, F. W. May 29, 1956 [June 23, 1955], No. 16576/56. Class 106 (2). In a feeler gauge assembly capable of being fitted into a rotating shaft, such as a spindle 12 of a machine tool, and including a work-contacting feeler 70 movable in a transverse direction to the axis of rotation, a linkage mechanism is arranged so that although the feeler 70 may move in either direction from a zero position the needle of an indicating gauge 84 is always actuated in one direction only. The assembly includes a slide 52 along which a holder 54 for the feeler 70 is movable in a transverse direction to the axis of rotation of the spindle 12, the feeler 70 being pivoted in the holder 54 and having a part 72 that can oscillate an elongated rocking-plate 34 about an axis parallel to the slide 52. The rocking plate 34 has attached to it a yoke 108 constituting a twoarmed lever. Resting on one arm is a vertical pin 100 and resting on the other arm is a vertical pin 102. When the plate 34 is rocked, the pin 100 or 102 that is caused to rise, depending on the direction of tilt of the plate 34, displaces a rotatable and axially movable sleeve 96 upwards and this in turn moves a two-armed lever 88 anticlockwise to give a reading on the dial gauge 84 that is consequently always actuated in the same direction. The feeler 70 may thus be applied to the internal or external surface of a cylindrical workpiece concentric with the spindle 12 and the gauge needle will in both cases be deflected in the same direction. Attached to the yoke 78 is a flexible corrugated tube 118 that can be bent to bear against a suitable fixed abutment so as to hold the dial gauge 84 stationary whilst the spindle 12 is rotated. Specifications 746,093 and 764,740 are referred to.

Title: Method of Providing an Electronic Device with a Protective Film of Glass Having an Opening Therethrough.
IPC: H01L23/29
Filed: 1968-04-09
Abstract: 1,172,645. Semi-conductor devices. HUGHES AIRCRAFT CO. 9 April, 1968 [1 May, 1967], No. 16958/68. Heading H1K. [Also in Division C1] In a method of providing a semi-conductor device with a protective film of glass having an opening therethrough, a film of polymeric material (e.g. a photoresist material) corresponding in shape and size to the opening required is formed on the surface of the device, a film of glass is then formed over the surface and the film of polymeric material, and the film of polymeric material is then removed from the surface so as to remove only that portion of the glass film overlying the film of polymeric material. A planar transistor, having its collector surfaces 2, base 4 and emitter 6 in the same plane, has a silicon dioxide coating 8 in which apertures are left for connection of the collector, base or emitter to their respective terminals. The device is then coated with a film 16 of photo-resist material, e.g. polyvinyl alcohol or polyvinyl cinnamate, which is then exposed over the areas corresponding to the holes to be left. The unexposed material is removed by a suitable solvent. A glass film is then formed over the whole surface, including the polymeric material by vapour deposition or sputtering. The glass covering the polymeric material, and that material are then removed. This is preferably done using a recognised solvent, penetration being achieved through the uncovered lateral surfaces and by the fact that the glass film puckers and becomes porous on the polymeric film. Alternatively, removal can be effected by heating the coated device to the charring point of the polymeric material, which during heating expands and " pops " off its glass covering. The polymeric film may be 3-4 microns thick and the glass film 6-7 microns thick.
