Abstract: 404,212. Vehicle spring suspensions ; springs. NOBLE, W., 10, Hillcrest Road, Grosse Point Farms, Detroit, Michigan, U.S.A. June 22, 1933, No. 17847. [Classes 108 (ii) and 108 (iii).] Vehicle suspensions comprise a wheel and arm structure pivotally connecting the wheel to the vehicle frame including torsional cushion devices located at the pivotal bearing supports between the said supports and the frame, the pivotal supports being spaced in the longitudinal direction as far apart as possible. The front and rear wheels 2, 3 are carried by arms 4, 5 and 6, 7 respectively each arm being connected to the chassis members at points widely spaced apart to prevent movement of the wheels in the longitudinal direction relatively to the chassis. The arms are connected to the chassis and to the stub axles by means of torsional rubber &c. springs comprising outer casings 10 and inner bushings with rubber blocks interposed. The outer casings are mounted on the chassis members by metal brackets and to the stub axles, locking pins 23 being provided to prevent rotation of the outer casings 10 in their mountings. The arms may be in two or more planes to give a parallel motion to the wheel bearing. In the modification shown in Fig. 14 one end of the arms may be held in the torsional spring while the other end is pivoted in a simple bearing, another torsional spring being connected to the arm intermediately. The outer casing 10 and the inner bushing may be provided with ribs adapted to enter the rubber block.

Class 44 In a double-ended barrel lock, of the kind comprising a thrower rotationally mounted between and about the inner ends of two key-operated plugs each of which has at its inner end portion one of two cooperating clutch elements which are key operable for selectively coupling the respective plugs to the thrower, each of the two slidable clutch elements is of L-shape, the foot 25 or 30 of each element being accommodated in a chordwise slot in the inner end of the respective plug and extending into the key slot of the latter, and the leg portion 24 or 29 of each element being guided in a bore located at one side of the key plugs, has a web portion 21 with a through slot 33 of V-form the limbs of which correspond with the chordwise slots in the plugs when the latter are in locked position. A radial arm 22 on the thrower operates the mechanism of the associated lock. The two clutch elements are urged towards each other by springs 32 in the bores in the plugs. The insertion of a key 14, Fig. 5, into either plug pushes the foot 30 of the corresponding clutch element into full engagement with the slot in the thrower while still remaining in engagement with the slot in the plug, and at the same time pushes the clutch element 25 of the other plug, which still remains locked, out of engagement with the thrower.

Abstract: 865,154. Protective arrangements. ALLISCHALMERS MANUFACTURING CO. June 9, 1958 [June 17, 1957], No. 18349/58. Class 38 (5). [Also in Group XXXIX] In a circuit-breaker control system, capacitance means supply a single pulse of unidirectional current to the control winding 10 of a transductor 5 to permit sufficient current to flow through the reactance or operating windings 8, 9 to energize the closing coil 3 of a circuit-breaker to close the circuit-breaker. In Fig. 1, the transductor is of the auto-selfexcited bridge-rectifying type and has a D.C. bias winding 11. The operating winding 10 is only energized during the charging period of a capacitor 31 when a " closing " push-button switch 16 is operated so that " pumping " cannot occur if the switch 16 is maintained closed when the circuit-breaker is closed on to a fault and trips open. The capacitor 31 discharges through a resistor 32 when the switch 16 is opened to prepare the system for a reclosing operation. In an alternative arrangement, the transductor is a simple saturable reactor with a D.C. control winding and A.C. operating windings. In each case the circuitbreaker is tripped on the operation of a switch 28 to energize a trip coil 4 which actuates a latch 58 to release toggle linkage 49, 50 and permit the circuit-breaker to open.

Title: Improved automatic adjuster for vehicle brakes

IPC: F16D65/52
Filed: 1966-04-27
Abstract: 1,136,132. Brake wear adjusters. GIRLING Ltd. 21 April, 1967 [27 April, 1966], No. 18352/66. Heading F2E. An automatic brake adjuster comprises a housing formed with an internal cylindrical chamber (14), Fig. 3 (not shown), in which a clutch member 13, Fig. 2, has a first lost motion connection through one part with a plate member 5 and is engaged by an abutment at another part and a rotatably-mounted wear-sensing member coupled through a second lost motion connection with a brake member (3), Fig. 4 (not shown), the wear-sensing member being coupled to the plate member. When the brakes are released shoe (3) is held against pin 1, Fig. 2, by the retraction springs and plate 5, which rotates with lever arm 2, acts on an inwardly-directed tang of spring 13 to lock the latter against the inner surface of cup 6. When the brakes are applied arm 2 can move freely within the movement range permitted by the clearance between the slot (15) in plate 5 and the spring tang. When the brakes are applied and adjustment is required the clearance (16) in the brake shoe slot and the clearance between the slot (15) and the spring tang are taken up successively so that any further movement of the lever arm 2 in the same direction winds up spring 13 which is thus unlocked from the cup 6 and advanced to a new datum position in which it locks when the brakes are released. A lug (18) on the plate 5 is engaged by the abutment formed in member 17 when the latter is rotated for the initial setting of the adjuster. In another embodiment the adjuster is enclosed with a two-part housing 34, 36, Fig. 7, with the plate and stem formed as a single integral member 40 and having seals 52, 54. In a modification of this embodiment, Fig. 8 (not shown) the spring tang (64) is bent into the axial direction so that it can replace the lug (18). In a further modification of this embodiment the spigot 46, Fig. 7, is replaced by a spigot and slipping clutch assembly 66<SP>1</SP>, Fig. 9. In all embodiments the initial adjustment member may have a square or hexagonal cross-section or be formed with a screw-driver slot and the wear sensing member may have a bifurcated end engaging with lost motion a pin on the brake member.

Alternatively, glass fibre cords may be wound about two spaced members to form an elongated loop which is subsequently whipped with glass fibres to bring the two sides of the loop together. Short lengths 12 of the rope, each carrying an insulator 13, may be connected together by loops 14 of glass fibre cord coated or coated and impregnated with insulating material. The insulators 13 may be made of a synthetic resin containing glass fibre filler and may be moulded about the rope 12 or cemented thereon. Porcelain bodies comprising a chain insulator may be linked together by means of the insulating rope. Specification 775,112 is referred to.

Abstract: 972,304. Pulse circuits. PYE Ltd. May 18, 1962 [May 24, 1961], No. 18751/61. Heading H3P. In a circuit for separating line and frame synchronizing pulses in television apparatus, the pulses are first differentiated and fed to a tuned circuit so as to give sinusoidal line pulses and largeramplitude sinusoidal frame pulses. As shown, the line and frame synchronizing pulses are separated at S from the video waveform and are differentiated by C1, R1 and fed to V1 having a series cathode circuit C2, L, tuned to a high frequency. The time constant of the differentiating circuit C1, R1 is selected so that the amplitude of sinusoidal pulses corresponding to the frame synchronizing pulses is larger than that of the shorterduration line synchronizing pulses. The sinusoidal pulses at the anode of V1 are clipped by diodes D1, D2, only the larger-amplitude frame pulses passing diode D2. The frame multivibrator V2 is arranged to be free-running at 20 c/s. and can be synchronized without adjustment at frequencies of 50 or 60 c/s. V3, V4 form an amplitude-stabilized bootstrap sawtooth generator as described in Specification 934,641.
