Title: Improvements in and relating to adjustable locking mechanism for altering or varyingpositions of objects or articles to which it is applied
IPC: A47B57/04
Filed: 1920-11-19
Abstract: 175,093. Connolly, W. J., and Sandham, P. H. Nov. 19, 1920. Link-work.-Relates to means for locking in adjusted positions relatively movable members forming part of lazy-tongs, Fig. 29, and comprises a trunnion or pivot pin fixed to each of the members, a common link or equivalent or equivalent device for connecting the two trunnions and a single locking means for locking the link to both trunnions simultaneously. The simplest construction shown in Fig. 1 comprises a plate a<1> fixed to a stationary member and carrying a pivot pin a, the movable member b<1> carrying the trunnion b. The two trunnions are engaged by split rings c<1>, c<2> which form the ends of the link c through which passes a rod e, the ends of which are left and right screw threaded so that on tightening up a wing nut e' carried by the rod e the split rings are caused frictionally to engage the trunnions simultaneously and to hold the members in their adjusted position. In modifications a cam-shaped finger-piece may replace the wing nut, the construction may be modified for use with three or more movable members which may not be coplanar, and instead of expanding the ends of the link c into split ring form the whole link may be split longitudinally, or the split ring may be formed in two pivoted portions.

Abstract: 730,811. Making chains. TAYLOR, H. G. Dec. 23, 1953 [Dec. 30, 1952], No. 32932/52. Classes 83 (2) and 83 (4). Bending; upsetting.-In the manufacture of a chain link part or shackle, a length of heated bar stock 20 is forced endwise into one limb 16 of a U-shaped tunnel formed in a two-part die 10 whereby the leading end of the bar traverses the bend 17 in the tunnel and passes along the other limb to a position level with the trailing end. The forcing punch 19 has two plungers 18 of equal length and whose stroke is such that at the end of their stroke they compress the bent bar to ensure that the latter fills the cross-section of the tunnel throughout its length. The bent portion 17 of the tunnel may have a cross-section different from or larger than that of the limbs; the final part of the stroke of the punch upsets the bar to cause it to fill the bent portion of the tunnel.

Abstract: 1,070,459. Step-by-step lifting jacks. J. A. SALDANA. Aug. 2, 1965 [Aug. 6, 1964], No. 32958/65. Heading B8J. [Also in Division E1] In a step-by-step lifting mechanism 22 in which lifting is effected by relative movement of a threaded central stem 20 and a housing 28 the screw is lifted by two sets of co-operating fixed wedges 58 and pairs of sliding wedges 74, Fig. 5 (not shown), one set in an upper chamber 42 of the housing 28 and the other set in a lower chamber 44. The movable wedges 74 are driven synchronously in opposite directions by threaded rods 80 actuated by an electric motor 108 through a gear train comprising a worm 118, Fig. 2 (not shown), and worm-wheel 120 and gears 122, 128, 132, 138. Micro-switches 142 reverse the motor 108 when closed by approaching movable wedges 74. Each chamber 42, 44 has a locking gear 82 driven by an auxiliary motor 86 which is also controlled by the micro-switches 142. The arrangement is such that one of the locking gears 82 carries the load (which is attached to the stem 20) while the other locking gear 82 " follows-up," the roles of the locking gears 82 interchanging on reversal of the motor 108 at the end of each horizontal movement of the movable wedges 74. The mechanism 22 may be used for raising concrete floors 208, Fig. 10 (not shown), during the erection of a building. For this purpose anchorage means 27, Fig. 9 (not shown), are provided. Heavy loads may be lifted by more than one mechanism 22 arranged in parallel. Cut-out safety switches 140 are provided.

Suitable bases are ammonia, hydroxylamine, hydrazine, amines, aniline, urea, guanidine, acid amides, phenyhydrazine, pyridine, quinoline or piperidine. Formaldehyde or its polymers or aldehyde of higher molecular weight may be employed. According to examples:-(1) Sheepskins are tanned in a bath containing an agent prepared from excess of formaldehyde and ammonia, then treated with sodium thiosulphate for a further period, washed with sodium carbonate solution and oiled. (2) Calf skins are treated with the same agent as in example (1), washed with sodium carbonate solution, and then with a solution of salt and hydrochloric acid. The leather is then chrome tanned with chrome alum and treated with barium chloride to fix the chrome tanning. (3) Vegetable tanned goats' skins are shaved and fulled in water and then treated with an agent obtained by the condensation of excess of formaldehyde with urea, followed by the addition of sodium thiosulphate. The tanning may be followed by brightening with oxalic acid or sugar of lead. Sulphonic acid condensation tanning agents are suitable to use in conjunction with the tanning agents described.

Title: Improvements in or relating to memory store arrangements
IPC: G11B5/596
Filed: 1969-07-02
Abstract: 1,260,888. Programmed position control. SIEMENS A. G. July 2, 1969 [July 3, 1968], No. 33429/69. Heading G3N. A memory storage arrangement, having one or more plate-like storage layers each carrying a plurality of tracks, includes a mounting, carrying read and write heads, which is positioned by a linear hydraulic motor. As shown, read-in and write-out heads 12, mounted on a common slide 14 are positioned with respect to a stack of memory storage plates 10 by a piston 28 in a cylinder 26. The position of the piston 28 is controlled by parallel-connected variable flow valves 22, 24. The position of the slide 14 is determined by an indicator 70 comprising linear inductance 72, arranged along a fixed guide for the slide, supplied from an A. C. source 74 and a coupled winding 76 on the slide. The voltage induced in the winding 76 has a frequency corresponding to that of the source 74 and an amplitude which varies in a sinusoidal manner with change in the relative position of the windings. The induced voltage is fed through an amplifier 78 to a phase-sensitive rectifier 80, producing a sinusoidal output and to a threshold detector 82 producing a pulse output each time the output voltage of the amplifier passes through zero. Each pulse is representative of the crossing of a storage track. Programme information from a data-processing installation, (not shown), is set into a control unit 90 and the required change in track position is fed, as a binary number, to a track difference register 50 the contents of which is fed to a decoder 52 together with an indication of sign R, V, denoting return or feed respectively. The output from the decoder 52 is fed via lines R or V, through a digital-analogue converter 54 to an amplifier 56 controlling a valve 22 and through a switch 58 to an amplifier 60 controlling a valve 24. In a coarse positioning mode a first controller system employing the pulse output of the indicator 70, counts down the contents of register 50 whereby the output of the digital-to-analogue converter 56, falls in a step-wise manner and the positioning rate decreases as the flow-rate through valve 22 drops to zero. When the contents of the register reaches zero the switch 58 is operated and a second controller system, employing the sinusoidal output of indicator 70, is brought into operation and the valve 24 controlled in a continuously variable analogue manner by the differential amplifier 60 to position the heads 12 at the programmed track. During the step-wise control of valve 22 the valve 24 remain fully open.
