Title: Push Button Signalling
Inventor: CRAGG WILLIAM DONALD
IPC: H04M1/23
Filed: 1967-12-07
Abstract: 1,198,308. Piezoelectric generators. STANDARD TELEPHONES & CABLES Ltd. 7 Dec., 1967, No. 55742/67. Heading H2A. [Also in Division H4] In a subscriber's V.F. keysender, each key is associated with a pair of piezo-electric elements and each element is connected to one of five monostable multivibrators whereby whenever a key is actuated a unique 2-out-of-5 U.F. signal of fixed duration is produced by the two energized multivibrators. As shown, depression of a push-button 15 is initially resisted by flexible limbs 19, 20, these limbs opening when sufficient pressure is exerted so as to allow a portion 16 of the spring-loaded key stem to impinge on piezo crystals 10, 11 and thus cause the latter to emit control signals to a pair of monostable multivibrators (Fig. 3, not shown). In another embodiment (Figs. 7-9, not shown) the keys are supported in resilient mountings and act upon bowed-springs when depressed. The bowedsprings may be formed integrally in a single sheet of springy material. The piezo elements may comprise a grid array of piezo strips, with push-buttons located at the cross-points (Figs. 6a, 6b, not shown). Fig. 10 (not shown) depicts the use of spring-loaded intermediate members which are arranged to impinge sharply on the piezo elements when their associated spring- loaded push-buttons are operated. In a similar arrangement (Fig. 12, not shown) the intermediate-members are initially made to touch the elements gently and then to move away from them rapidly when the push-buttons are actuated. The use of strips of piezo material which are supported at one or both ends so as to be bent by actuation of a push-button is mentioned with respect to Figs. 13 and 14 (not shown).

Abstract: 1,244,668. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 3 Dec., 1968 [6 Dec., 1967], No. 57223/68. Heading H1K. A semi-conductor device bears an apertured insulating layer through which a first metallization makes ohmic contact with the semiconductor. A second apertured insulating layer is provided on the first insulating layer and metallization; the aperture exposes part of the first metallization, and a second metallization is provided to contact the first metallization in the second aperture and to overlap the second insulating layer. A third apertured insulating layer is provided over the second insulating layer and metallization and a third metallization is provided to contact the second metallization in the third aperture and to overlap the third insulation. In the embodiment described, such contacts are used to make connection to a planar transistor having a base region in which two double comb emitter regions are formed. Separate contacts are made to the base region and to each of the two emitter regions (which are shorted together in use by external circuitry). Each three layer contact structure is completed by a solder coating and a reflow-soldered contact ball. The first metallization of the base contact covers substantially all of the base region (and is thus interdigitated with the two double-comb emitter electrodes) and overlaps the first insulating layer to project over the collector-base junction to control its properties. A heavily doped anti-inversion ring is formed in the collector region to entirely surround the base region and this ring is provided with its own contact layers. The Specification gives details of the production of the transistor and illustrates the complex shapes of the various metallizations which differ from layer to layer.

Stiffeners 29 give the member rigidity. In a modified main member, Figs. 3-5 (not shown), strips of metal are secured between the inner and outer walls to provide stiffening and heat conduction away from the hot region. In a modified intermediate member Figs. 6-9 (not shown), axial admission ports (36) are fed by ducts formed by shaped sheet metal members 37  co-operating with the side walls (20<SP>1</SP>, 21<SP>1</SP>) and communicating with ports (38) in the peripheral wall (22<SP>1</SP>). Each of the members is assembled by tack welding all the components to one side wall, covering all the joints with copper brazing paste, locating the other side wall, and heating in a brazing furnace. A wear-resistant coating on the rotor-contacting surfaces may be sprayed on and hardened during brazing. Alternatively the components may be electrolytically coated with copper which in the brazing furnace will run into the brazing gaps. The components may be welded together using electron beam or laser beam welding. The wear-resistant coating is preferably an alloy containing chromium boron and silicon with cobalt or nickel and possibly additions such as tungsten carbide.
