Title: Improvements in or relating to travelling towers for hoists
IPC: B66C13/00
Filed: 1933-02-18
Abstract: 416,782. Lifts; distributing stress uniformly. EXPRESS LIFT CO., Ltd., and STEVENS, J. W., Greycoat Street, Victoria Street, London. Feb. 18, 1933, No. 5067. [Classes 78 (ii) and 78 (iii).] Travelling towers in general, and more especially those which support a lift cage travelling on guides inside them, are prevented from distortion by a system of tensioned ropes and counterweights which equalize the hauling strain. The invention is applicable specially to storied garages wherein ranges of storage compartments situated at different levels are served by the traversing of the tower and raising and lowering of the lift. Fig. 3 shows one arrangement in which ropes 6 fixed at different levels to the tower are given a few turns round drums 16 and then pass to a single counterweight 7 on each side of the tower. By rotating the drums simultaneously in opposite directions, through the medium of the motor 20 and bevel shaft 19, one weight 7 may be raised and the other one simultaneously lowered, thus effecting the traversing of the suspended tower on the runway 5. The drums 16 may be omitted at one side of the appliance, the traversing in one direction then being effected by the one counterweight when the opposite one is raised by the driving-gear. The two ropes 6 at one level may be replaced by a single rope connected at two points to the tower. The lift 2 is raised and lowered by hoisting-gear 3 on the travelling carriage supporting the tower. Figs. 1 and 2 show a modified arrangement in which the ropes 6 pass upwards over drums 9 on a driven shaft 11 and thence round pulleys 15 on a common counterweight 7 to a fixed point. Where two towers are used in the same garage well, interlocking means is provided for the driving- gear to prevent collision, and also so that they can be operated as a unit when desired.

Filed: 1974-02-04
Abstract: 1459247 Linear motors S BENOWITZ 4 Feb 1974 [5 Feb 1973] 05139/74 Heading H2A [Also in Division B2] Apparatus for moving conductive material comprises two rows of electrically excitable spaced magnetic poles each pole face being opposite a space in the other row, the two rows defining a gap between them. The poles are energized by a multi-phase A.C. supply to produce a travelling wave field in the gap e which transmits motion to articles 35. These articles may be non-ferrous components in refuse carried through the stator on a conveyer belt 13 (Fig. 1, not shown). The articles 35 are moved across the belt and deposited in containers at the sides. In a second use, the stator is aligned along the path of travel (Fig. 7, not shown) and aluminium can lids are moved therealong. By providing two or three parallel paths and by suitably energizing the poles, motion can be induced in any direction along the paths or laterally between the paths. Thus single streams may be split, or vice versa and articles either concentrated at the centre of a stream or forced to the edges.

Abstract: 848,309. Hooks. BLACKBURN GROUP Ltd., and CRAWSHAW, A. H. Feb. 16, 1959, No. 5312/59. Class 89(2). In a release-hook in which separation of the members is effected by relaxation of the tension between the joined-members, the jaws A, A<1> together form, when closed, a circular-aperture at one end for gripping the member to be fastened, and have curved-extensions A<2> at the other end. They are pivotally-mounted on a body-member consisting of two flat U-shapedplates L bolted to a further U-shaped-member G. Mounted between the plates L is a spindle E carrying an eye-member F at one end, and having two distance-pieces B, C and a fixed stop-piece D at the other, the arrangement being such that the piece C is free to slide along the spindle between the members B, D, which are fixed thereto. Between the stop-piece D and the bodymember G is a compression-spring K and a washer H. With the jaws in the open-position as in Fig. 4, the member to be gripped is fed into the aperture between the jaws, which are then squeezed-together by hand, moving the extensions A<2> apart and allowing the spring to move pieces B, C, D, to the position shown in Fig. 1, with the extensions gripping reduced portion C<1> of the piece C. As a load is applied to the member F, the spring K is compressed and members D, B, move until the portion C<1> is displaced from between the extensions A<2> and replaced by member B, as shown in Fig. 3. The member B is of less width than the portion C<1> of the member C, to allow easy entry between the extensions. Further increases in load have no effect on the fastener, but reduction to a figure below that exerted by the spring, will allow the spring to expand and disengage the jaws.

Fig. 4 shows part of a circuit for a sampling oscilloscope in which the tested wave is sampled by means not shown; the samples are smoothed and passed via an impedance matching circuit comprising transistors T10 . . . T13 to electrode 31 of a symmetrical transistor T9, where it is compared with a reference voltage from potentiometer VR1 supplied via a further impedance matching circuit comprising transistors T14 . . . T17. Symmetrical transistor T9 is made conductive by negative half-cycles of a square wave fed to the base from frequency dividing bi-stable circuits comprising transistors T5 . . . T8, driven by a multivibrator T1, T2, the conductive direction of T9 being dependent on the relative magnitude of input voltage at terminal 2 and reference voltage from VR1. A square wave is thus fed to a seven-stage differential amplifier 13 giving waveforms X, X, the polarity of which is dependent on the relative magnitude of reference and input voltages. Negative half-cycles of waveforms X, X are gated at 16 and 17 with outputs from the bi-stable chain T5 . . . T8 and with the differentiated multivibrator waveform A so that the bi-stable circuit comprising transistors T20 . . . T23 assumes one of its stable states with T21, T23 conductive and T20, T22 non-conductive or vice versa depending on the relative magnitude of reference voltage VR1 and input voltage at terminal 2. Transistors T24, T25 are respectively made conductive in the two states of the circuit so as to charge or discharge capacitor C2, the voltage across which is used to delay the sampling pulses so that the amplitude of sampled waveform at terminal 2 becomes equal to the reference voltage at VR1. The sampling pulses may be generated by an avalanche transistor (not shown) triggered when the combined voltage of a sawtooth wave and the D.C. bias reaches a predetermined level. The output at 35 is used to control the sampling trigger delay so that the delay increases until the amplitude of the samples equals the reference voltage. Multiple sampling system-The reference voltage may be switched successively to different levels, each used with a sampling pulse at a different time. An additional set of gates and bi-stable circuit is used for each sampling level.
