Abstract: 1,134,507. Laminates. INTERNATIONAL BUSINESS MACHINES CORP. 8 March, 1966 [25 March, 1965], No. 10024/66. Heading B5N. [Also in Divisions G4 and H1] A laminate comprises a first lower substrate of copper-clad glass or paper-filled epoxy laminate, a second layer of polyethylene terephthalate deposited on the substrate, a third layer of polyethylene terephthalate-copper laminate, and a fourth elastomeric layer, e.g. of neoprene, " Hypalon " (Registered Trade Mark), " Viton " (Registered Trade Mark) film rubber, or a urethane synthetic rubber. A layer of silicon grease may be provided between the third and fourth layers. The first substrate has gold plated on its upper surface, and the third layer either has gold coated on its lower surface or may itself comprise a gold layer. The laminate can be formed by any thin film technique, e.g. photo-etching.

Abstract: A new capacitive tablet has a single layer in which electrodes provide capacitive coupling with a pen to produce signals that correspond to the X and Y dimensions of the position of the pen on the tablet. The electrodes in the single layer are in the form of pairs of complementary shaped, closely adjacent, conductive elements that extend in the Y dimension of the tablet. For sensing the pen position in the Y dimension, an alternating voltage is applied between the two elements of a pair and the pen receives a signal that is a function of the pen position in the Y dimension. The tablet includes a number of such pairs, each having a different X dimension position, and for sensing the pen position in the X dimension, the two electrodes of a pair are given an alternating voltage that differs progressively across the X dimension of the tablet.

Abstract: 1298290 Retractive switches INTERNATIONAL BUSINESS MACHINES CORP 21 Dec 1970 [23 Jan 1970] 60508/70 Heading H1N A switch comprises a fixed contact 27; a movable contact 24 mounted on a diaphragm 23 and an actuating member 20 located on the other side of the diaphragm to the contacts and having a projection 21 facing the diaphragm whereby on depression of the actuating member which is of elastic material the projection urges the contacts into engagement. The contacts 24, 27 are gold-plated copper laid on polyester diaphragms 23, 30; a separator sheet 25 having holes aligned with the contacts is placed between them. The actuating member is of solid neoprene and besides projections 21 has further, shorter projections 22 which limit travel and prevent damage to the contacts or diaphragm 23. Above the actuating member rests a thick block 16 of soft closed-cellular neoprene and above this, resting on a rigid aluminium frame 15 is an actuator sheet 10, 14 of polyurethane elastomer having raised portions 11 marked with indicia (Fig. 2, not shown). The sheet 10 can be readily removed and replaced by another bearing alternative indicia. The block 16 gives the switches a suitable "feel" and allows pretravel and overtravel. The stop projections 22 may be arranged in a circle or a square depending upon the shape of the raised operating portions 11; they may be discrete projections or a continuous ring surrounding the projection 21. More than one projection 21, each operating a pair of contacts, may be associated with a group of projections 22 below a single portion 11.
