Title: Improvements in worm geared hoisting appliances
IPC: B66D3/16
Filed: 1919-12-13
Abstract: 148,093. Vaughan, W. H., and Wood, F. Dec. 13, 1919. Geared pulley-hoists; self-sustaining gear.-In worm-geared pulley-hoists, for lowering the load, the hand-chain wheel is first disengaged from the worm shaft by a lever, further movement of which releases the self-sustaining brake. The handchain wheel a is coupled to the worm shaft f by a sliding brake disk g which is controlled by a lever r through a rod s. The lever is pivoted at q<2> to the rod and also at q<1> to a link p<3> pivoted on another link p which releases the self-sustaining brake k through a rod f<1>. Thus as the lever r is depressed, the wheel a is first de-clutched, and when a block s<2> on the rod s bears against a stop t, the links p<3>, p are operated to release the brake k, the load being lowered under control of the centrifugal or other brake g. Specification 130,167 is referred to.

Abstract: 536,272. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd. (Maatschappij van Berkel's Patent N.V.). Dec. 2, 1939, No. 31351. [Class 28 (ii)] In a slicing-machine comprising a gravity-feed substance carrier 7 inclined perpendicularly to an inclined knife 11, a slice receiver 15 is pivoted at 23 on the carrier and lowered angularly to make room for successive slices. In Fig. 1 the receiver is lowered step by step by means comprising a link 25 pivoted on a pin nut 26 which travels along a screw 27 having ratchet-and-pawl mechanism 30 actuated by a stop 32 at each traverse of the carrier. The receiver is re-set by releasing the nut 26 and sliding it along the screw. The stop 32 may be adjustable to vary the rate of descent of the receiver, e.g. as in Fig. 3 in which the stop is one end of a pivoted lever 32A the other end of which is moved by screw means 22, 34, which at the same time, by means of screw thread 18, finger 19A, &c., adjust the slice-thickness plate 14. In a third example the stop is replaced by a cam plate fixed to and raised and lowered with the slice-thickness plate 14, which is mounted not on the knife bracket as in the two examples shown but on the machine base. Specifications 530,589 and 532,940 are referred to.

An unwinding reel, having draw-off means for straightening wire drawn off a coil of wire fitted to the reel, includes a gripper assembly having a mouth disposed before the draw-off means for clamping the end of the wire and which is controllably movable to convey the clamped wire end to the draw-off means, the mouth being disposed radially of the coil at a first position at which it is to receive or clamp the wire end but being adapted to pivot during the controlled movement to align the clamped wire end with the entry to the draw-off means so as to facilitate engagement of the wire end therewith. The end of a coil 30 of wire on a rotatably mounted reel drum 3 is introduced by cable tackle 32, 33 into a mouth 12 of a gripper assembly 11 positioned so that the mouth 12 is radial of the coil 30. The wire is then clamped in the gripper means 11 by a member 13 moved by a cam 25 and the cable 33 released.

Look-out reflectors. - Observation mirrors which may be combined with licence-holders, map-carriers, &c. are supported by ball joints on adjustable brackets having various locking devices, additional anti-vibration brackets or supports being also provided. In the construction shown in Figs. 1 and 2, the mirror casing R is supported by a ball joint S in the end of an arm F, the ball being held by means of the concave end of a screw W having a lock nut Z which is prevented from slacking back by a spring-controlled bolt R<1> or by a flat spring PP. The arm F is secured by a bolt J against the outer end of a conical serrated plug D which fits into a boss C on one of the clamping members A, B by which the device is secured to the wind screen or other part of a vehicle. The bolt J is fitted with a nut K which may be formed with a series of grooves M one of which is engaged by a spring-controlled locking bolt P. The nut K may be locked by a plate KK which also serves to lock the nuts on the additional clamping bolts H. The arm F may be steadied by an additional anti-vibration arm S' which is secured to the clamping members AB and may also be connected bv an extension S‹ to some other part of the vehicle. A holder A<1> for a licence, map &c. may be secured to the mirror casing or to the bolt W or to a pin T<1>, or may be arranged at the back of the mirror. In a modification the arm F may be let into the taper socket D which is split so as to clamp the arm when the ball J is drawn up.

Abstract: 492,006. Automatic exchange systems. LORENZ AKT.-GES., C. Nov. 19, 1937, No. 31893. Convention date, Nov. 20, 1936. [Class 40 (iv)] [Also in Group XL] In a carrier current signalling system, speech and ringing signals are separated by transmitting speech on a modulation band of 300 to 2400 cycles, the carrier frequency fo being suppressed, and ringing signals on a modulation band of 0 to 300 cycles without suppression of the carrier frequency fo so that the two signals may be separated at the receiver by filters, one having a pass range of fo + 300 to fo + 2400 and the other a pass range of fo + 300. Carrier current from the generator 1 is modulated in the modulator 2 by speech currents from the device 3, and, after suppression of the carrier frequency in the modulator 2 or the filter 4, is fed to the line a, b over an amplifier 5. Ringing signals in the form of interruptions, e.g. dialling impulses, or unmodulated carrier current or of carrier current modulated with a continuous or interrupted audio-frequency of 0-300 cycles, are generated in the device 6 and fed to the line over the amplifier 5. After passing the amplifier 7, the received signals are separated by the filters 8 and 9 with passing ranges of fo+300 to fo+2400 and fo+300 respectively. The speech signals are demodulated in the device 10 and the calling signals are impressed upon a responsive device 11.

Abstract: 797,142. Waveguides. SPERRY RAND CORPORATION. Nov. 10, 1955 [Nov. 10, 1954], No. 32193/55. Class 40 (8). [Also in Group XL (c)] A waveguide comparator for deriving signals corresponding to the sum and difference of pulses received in different sectors of a horn antenna comprises three magic-T's whose symmetrical arms are arranged parallel and contiguous to each other. Such magic-T's are described in Specification 739,526. The horn 96, Fig. 7, is divided into four equal sectors by horizontal and vertical septums 24, 22, the vertical septum 22 forming a common wall between the first and second junctions which have oppositely-arranged shunt arms 76, 78 (Figs. 3, 4). The pairs of vertically-opposed symmetrical arms of these two junctions are formed by the horizontal septum 24 which terminates at the junctions. The vertical septum 22 extends into the region of the third junction and forms a common wall between the horizontally-opposed series arms of the first two junctions. These series arms also form the symmetrical arms of the third junction which is provided with a shunt arm 62 and a series arm 54. A signal corresponding to the sum of the pulses received in the four sectors of the antenna is transmitted to the series arms of the first two junctions and thence to the series arm 54 of the third junction. A difference in the amplitudes of pulses received in the vertically-opposed sections of the antenna will produce a corresponding signal in the shunt arms 76, 78 of the first two magic-T junctions whilst a difference in the amplitudes of signals received in the horizontally-opposed sections will produce a corresponding signal in the shunt arm 62 of the third magic-T junction. The outputs of shunt arms 76, 78 are combined at a further T-junction (Fig. 5, not shown). Various matching devices such as fins 68, 70, plate 71, tapered blocks 79, post 92 and rod 94 are used to reduce reflection at the junctions. Monitor signals may be mixed with the received signals by means of guides 98, 100, 102, 104 which are directionally coupled to the comparator by crossed slots 105. In a modification (Figs. 8-10, not shown) the horizontal septum 24 is omitted. In this case a pulse received from above, or below the axis of the horn antenna excites not only the dominant H 10  mode in the two guide sections formed by the septum 22 but also the second order H 20  mode which the two sections are wide enough to support. The second order mode is coupled to the shunt arms 76, 78 but not to the arms 62 or 54 which are dimensioned below cut-off for this mode.
