Abstract: 1,225,870. Cleats. C. H. ARNOLD. 6 Aug 1968 [29 May, 1968], No. 37447/68. Headin E2A. A device for gripping a flexible line 24 such as a rope comprises in combination, means 50, 50' having transverse members 58, 74 extending therebetween positionable on opposite sides of the line, means 26, 26' for applying a torque to rotate said first means so as to move said members transversely with respect to said line to contact the line and haul it into a hitch such that the line is securely gripped by the device, said first means being constructed whereby counter-torque can be simultaneously applied thereto for controllably releasing said line. In the construction shown the means 50, 50' are a pair of circular side plates, and their shapes allows them to be rotated manually to apply the counter torque; the member 58 is a projection from the plate 50 which extends through an opening in the plate 50' its end portion being welded to the plate 50'. The member 74 is a pin which is slidable in a bore 78' of the plate 50' and which has a snap ring 84 disposed in a circumferential recess which engages a shoulder at the end of a counter bore 78 in the plate 50 when the pin 74 is in its fastening position. The means 26, 26' for rotating the plates 50, 50' consist of a pair of control lines which are respectively secured to the plates 50, 50' and extend in circumferential grooves in the plates. The free ends of the control lines are connected together by a clevis 32. Each of the plates 50, 50' has a hub 59, 59' and attached to each hub is a generally triangular plate 90, 90' each plate being attached to its hub near one apex and the plates being connected together near their other apices by tubular stems 102 on which rollers 100 are mounted. One roller bears on the line 24 and the other on the control lines 26, 26' and in the operative condition of the device the plates prevent withdrawal of the pin 74. In the inoperative condition of the device the plates can be rotated to align notches in the plates with the pin 74 to enable the pin to be withdrawn so that the flexible line 24 can be positioned between the projection 78 and the pin 74. In Fig. 1 the device is shown for gripping the line 24 which is supporting a platform 10 the line passing round pulley blocks 17, 19. The control lines are attached to a bracket 28 which is itself attached to a loop 14 of the platform and the arrangement is such that when the device is in engagement with the bracket it is in its releasing position in which the line 24 passes straight down between the projections 78 and the pin 74 with the control lines are substantially contained in the circumferential grooves of the plates 50, 50'. The upper surface of the bracket is arcuate so that it engages the circumference of each plate 50, 50' and the bracket is bifurcated so that the line 24 can pass through the bracket. Other uses of the device are described.

Headings E1A and E1W. A building structure comprises parallel supporting uprights 1 to 8 which may be L- shaped as in upright 7 or rectangular as in upright (1) Fig. 15 (not shown). The width of panelling which is fitted between the uprights is slightly less that the distance between the uprights and neoprene gaskets set in a groove along the length of the uprights and around the circumference of the panelling seals the gap. The panelling is formed of plastic coated steel. Each panel is hollow or filled with rigid polyurethane foam, wood wool or concrete and may be either "single" Fig. 9 (not shown) with one peripheral groove (102) or double Fig. 10 (not shown) with two peripheral grooves (103), (105) and a central channel (104) between. Two single panels e.g. 134, 135 may be fixed together spaced by a packing piece when forcing an outside wall with a clip 131 of spring steel over an insulation strip of P.V.C. The panels are fixed to the uprights by vertical steel locking straps 136, 137, mounted on a P.V.C. lining 123, and engaging the central channel in the panel, being clamped to the uprights by bolts 139, 140 after being : slotted into engagement. The panels may include windows doors &c and the junction of one panel to another may be by means of an integral tongue engaging the peripheral groove or a cruciform load transmitting strip. When a wall panel is made up from such panels the panels may be locked to a strengthening cross member by means of a turn buckle. Service ducts (188, 189) Fig. 17 (not shown) are fixed to the wall panels at their junction with the floor or roof panels and are concealed by skirting (197, 199).

Abstract: 1,259,069. Semi-conductor devices. HONEYWELL INFORMATION SYSTEMS ITALIA S.p.A. 17 June, 1970 [24 June, 1969], No. 29468/70. Heading H1K. In a transistor of the kind in which the base region comprises part of an epitaxial layer isolated from the remainder of the layer and from the substrate, which is of the same conductivity type, by means of a region of the opposite conductivity type forming the collector region, the emitter region being formed within the base region, the impurity concentration of the part of the base region surrounding the emitter region is higher than that adjacent to the collector region and decreases with increasing distance from the emitter region. This impurity profile of the base region provides a drift field to increase the transit time and gain while maintaining the high breakdown voltage of the transistor. As shown, Fig. 2, N type impurities are diffused into part of a P + type substrate 23 and a P type epitaxial layer 24 is deposited, the N type impurities diffusing into the initially deposited part of layer 24 to form an N+ type buried layer 25. An N + type frame region 26 is diffused through the epitaxial layer to contact the buried layer 25, and together these regions constitute the collector of the transistor. A P + type region 28 is diffused into the part 27 of the P type epitaxial layer surrounded by the collector region to form a drift field zone within the base region, and an N + type emitter region 29 is diffused into region 28. The surface is protected with an oxide layer (not shown) and collector, base and emitter electrodes 16, 17 and 18 are provided. The transistor may form part of an I.C., the junction between the collector region 25, 26 and the surrounding part of the epitaxial layer 24 and the substrate 23 being reverse biased to provide isolation. A P+ type frame region 15 may be provided round each device to reduce parasitic transistor action between adjacent collector regions. This frame region 15 may be formed simultaneously with the diffused part 28 of the base region.
