Title: Improvements in or relating to methods of building
Inventor: WHITTING ALAN CHARLES
IPC: E04B1/35
Filed: 1970-12-17
Abstract: 1293689 Method of erecting a building A C WHITTING 17 Dec 1970 [23 Dec 1969] 60019/70 Heading E1S A multi-storey building is erected by (1) constructing on the site a construction platform 13 covering the floor plan of the building, (2) elevating the platform in stages whilst constructing vertical columns 11, service shafts 10, &c. from the platform, (3) fixing the platform at the top of the building to the vertical elements to form a stable structure, (4) mounting floor hoisting means, e.g. jacks 42, at the tops of the vertical elements, (5) constructing at ground level 36 a floor complete with perimeter walls and fittings and hoisting it up one or two storeys to act as a roof whilst (6) constructing the next floor at ground level, the previous floor then being hoisted to its final position, and (7) repeating steps (5) and (6) for each floor. For very tall buildings, more than one construction platform 13 may be used, each platform being fixed at a fraction of the height of the vertical columns, which are constructed from the uppermost platform, and floors are then cast in reinforced concrete on each platform and lifted by hoisting means mounted at the level of the platform above. The construction platform 13 is provided with formwork 14, 15, 16, 17 for casting the vertical columns, &c. in reniforced concrete and lifting gear 26, 28 by means of which the platform "climbs" up on the constructed parts of the vertical columns.

Title: Telescopic members
IPC: F24F7/02
Filed: 1972-03-22
Abstract: 1338260 Stud and socket fastenings A A GRAHAM and A ANDERSON 22 March 1972 [22 Dec 1970] 60999/70 Heading E2B [Also in Divisions F2 and F4] A fastening for two telescopic members, one member 10 being axially and rotatably movable relative to the other member 11, comprises a slotted ring 14 on the member 11 and corresponding projections 15 on the member 10. The three slots 20, 21, 22 and the corresponding projections 23, 24, 25 are spaced 120‹ apart and have differing widths and radial depths the narrowest slot 20 and projection 23 having the largest radial depth. To fasten the members in an extended position, the member 10 is moved axially so that the projections pass through the corresponding slots in the ring 14, and the member 10 is then rotated to hold the slots and projections out of alignment. If during this rotation of the member 10 a narrow projection overlies a wider slot the tips of the projection will engage the ring 14 and prevent the projection from tending to fall through the slot and cause canting of the members 10.

Patent GB-766947-A (GB)
Abstract: 766,947. Totalisators; counting-apparatus. BELL PUNCH CO., Ltd. Dec. 22, 1954 [Dec. 30, 1953], No. 37075/54. Classes 106 (1) and 106 (3). Means are provided in a race-course totalizator for taking a printed record of the numbers displayed by the individual contestant counters and preferably by the totals counter. As shown, the individual counters 48, Fig. 2, and the total counter 78 are mounted on a re-setting shaft and are provided with type numerals exposed through a slot 52 in a counter cover plate 54 and may be covered by an assembly of record sheets comprising an upper carbon B and record sheets A having holes F to register with pins 116 secured to the frame. Printing is effected by means of a roller assembly 140, 143, Fig. 5, supported by a pin 142 in a carrier 138 whose flat stem may travel in a slot 136 of a track 134 mounted between arms 128, 130 pivoted to the frame at 126 so that when not in use the printing means may be swung into the left-hand position shown in Fig. 5. During printing, affected manually by traversing the roller assembly along the track by a knob 144, rollers 143 run over the plate 54, the continuous carbon trace thereby produced being printed on the black lines D on the record sheet, and the roller 140 carbon prints the current counter totals in the appropriate spaces C. The record sheets from each machine may be removed and assembled together on a single board to facilitate further totalling. The zeroizing shaft 82, Fig. 7, has at one end a ratchet 86 co-operating with a pawl 94 pivoted between two arms 88, 90, one arm 88 being provided with an operating handle 92. Three oscillating movements of these levers rotate the ratchet to zeroize all the counters. At its other end the shaft 82 has a detent mechanism which has to be released before zeroizing may be effected and a further cover-plate is provided which holds the detent means in locking position and also prevents depression of the selector keys unless the cover is properly in position. The pins 116 are also locked in a non-operating position by this plate. The individual counters 48 are each operated by a slide 20, Fig. 3, having a slot 42 engaging a pin 44 on a bellcrank 46 which actuates the counter. An operating rod 18 which is reciprocated once per machine cycle by an eccentric 10 on the shaft 8 runs under an edge 28 of the slide 20 unless the appropriate selector key 2 is depressed, whereby a lever 32 is turned counterclockwise by a ledge 6 on the key 2 to move into the path of the rod 18 and to communicate its movement to the slide 20 to which the lever 32 is pivoted. A similar mechanism is provided for the total counter. Specification 332,942, [Class 106 (iii)], is referred to.

Title: Electrical bridge circuit with compensation for long-term drift
IPC: G01V3/10
Filed: 1979-02-09
Abstract: An electric sensing circuit, typically a metal detector, includes a bridge including inductors (L1, L2). The out-of- balance condition of the bridge is stored on a capacitor C1 and a compensating signal is applied to the bridge output at A1 in dependence upon the stored value of the charge. The stored value of the charge is only updated in response to relatively slow changes in the out-of-balance condition of the bridge, whereupon switch S1 is closed as soon as the imbalance voltage, delayed by network R6, C2, exceeds positive or negative threshold Vref1 or Vref2. Relatively rapid changes in the out-of-balance condition, whereupon the undelayed imbalance voltage exceeds a threshold Vref3, are used to provide an output signal for alarm or measuring purposes, and the arrangement is such that switch S2 is also operated to inhibit circuit A4, A5, S1 from automatically balancing the output signal giving the alarm or measurement. <IMAGE>
