Title: Improvements in or relating to the control of hoists and cranes
Inventor: ROBERTS LEONARD
IPC: B66C13/40
Filed: 1950-06-05
Abstract: 711,132. Electric control systems. CLAYTON CRANE & HOIST CO., Ltd. June 5, 1951 [June 5, 1950], No. 13942/50. Class 40 (1). [Also in Group XXX] In apparatus for controlling a crane or hoist from a distance by radio, a transmitter under the control of the operator transmits a modulated carrier, the modulations being selected at the receiver by note selector cricuits of the type in which all frequencies except the selected one are attenuated by negative feed back. The transmitter (Fig. 1) is self-contained, miniature components being used throughout and may be carried in a haversack by a hoist operator. The radio-frequency section comprises a regenerative crystal oscillator and frequency multiplier 12, which feeds the grid of a power amplifier 13 in the anode circuit of which is a resonant parallel line feeding the antenna by either a balanced or co-axial low impedance matched feeder. The output of the transmitter is modulated at one of a number of audio frequencies produced by closing one of press buttons 18 to 21 so that one of crystals 17b to 17e produces a low frequency oscillation which beats with an oscillation produced by a further crystal 17a. This beat frequency signal is amplified at 22, and impressed on the radiofrequency signal so that a radio-frequency modulated at a frequency corresponding to the button pressed is transmitted. The receiver (Fig. 2).-The audio frequency modulated signal received at the antenna 26 feeds the radio-frequency amplifier 28 through a balance or co-axial low impedance line. If the receiver operates at or above a frequency of 465 m.c.'s the amplifier 28 mixer 29 and local oscillator employ cavity resonators and disc seal valves though this is not necessary for the second frequency changer 31 and intermediate frequency amplifiers 32, 33 or detector 34. A noise limiter is included before the low frequency amplifier 36, which feeds a number of tuned circuits 37 to 40 (see below) each tuned to the beat frequency produced by one of push buttons 18 to 21 (Fig. 1) and operating one of relays 37 to 40. Each relay effects a different control on the crane e.g. lowering or hoisting and all relays are interlocked so that only one control may be operated at a time. The frequency selection is accomplished by a number of circuits such as are shown in Fig. 3. each of which strongly attenuates all frequencies except the selected one by means of filter circuit 43 and a negative feed back connection.

Title: Improvements relating to the filtration of fluids
Inventor: BUCKMAN KENNETH ERNEST
IPC: B01D25/26
Filed: 1953-05-19
Abstract: 773,875. Filters. GENERAL MOTORS, Ltd. April 1, 1954 [May 19, 1953 and Aug. 7, 1953], Nos. 13983/53 and 21857/53. Class 46. A filter unit 9, Fig. 1, consists of a plurality of elements 14, Fig. 6, stacked on a perforate tube 15 between end plates 16, 17 which hold the elements in endwise compression. Each element is formed of two sheets 22, Fig. 2, of resin impregnated paper, each having a circle of spaced dimples, 23, which abut in opposed pairs to space the outer edges of the two sheets, Fig. 6. Radial and circular grooves 24, 25 are also provided. A metallic or fibrous washer 27 is placed between the inner peripheries of the two sheets forming an element and a metallic clamping member 28, having indentations 32 to provide radial channels between adjacent elements, is applied. The endwise compression suffices to form a fluid-tight seal at the outer edges of the sheets of adjacent elements, though these edges may be dipped in adhesive. Oil pressure during filtration also assists sealing. In Fig. 9 (not shown) the outer edges of adjacent sheets are sealed by a metallic clamping member, and the inner edges of the sheets of each element are sealed in contact by a metallic clamping member which, in section on the left of the axis, is like the mirror image of a figure " 5," the upper part of which acts as a clamp and the lower part, provided with recesses, as a washer. In Fig. 10, (not shown) the outer edges of adjacent sheets are sealed by adhesive and the inner edges of the sheets of each element are separated by a washer, while the inner edges of adjacent elements are spaced only by the grooves 24, 25. The tube 15 of Fig. 1, may be replaced by a V-section centralising member, Fig. 11, (not shown), or may be dispensed with, and the elements stacked within a perforate casing (additional to the casing 11, Fig. 1) to the end edges of which the plates 16, 17 are secured by rolling, Fig. 12 (not shown). The elements may be six-sided and relatively located by their apices. The relative sizes of element and casing in a unit of the type of Fig. 1 may be so chosen that the elements are located by the casing, rendering both the tube 15 and the perforate casing of Fig. 12 unnecessary. In Fig. 19 the elements are relatively located by tags 437 bent in from clamping members 438, and again render further locating means unnecessary. In Fig. 21 washers 539 have recessed flanges 540 tapered at 541 to facilitate nesting of adjacent elements. Specification 761,352 is referred to.

The air in the sack 2 is maintained under slight pressure by the provision of an internal spring 3 or an external elastic band, by giving the sack a bellows form by making the side walls reentrant, or by so suspend. ing the regenerator as tc put the sack under a slight flattening tension. The air inlet 1<a> communicates with the regenerator through a conduit 7 which may be within the sack, as shown, or outside it. The regenerator may be suspended from the person as by a belt, and the sack 2 may be elongated to permit carrying the regenerator at the waist line or at the back of the user. The conduit 7 is connected to a central conduit 6b in the regenerator casing communicating with the injector 6<a>. In order to ensure circulation during both breathing phases, the injector may be constructed to circulate during each breathing cycle about double the volume of air inhaled. The resistance of the reagents is decreased by increasing the number and size of the reagent compartments of the regenerator. Specification 411,214 is referred to.
