Title: Improvements in or relating to electrical signalling systems
IPC: H02J13/00
Filed: 1943-06-03
Abstract: 566,122. Electric systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and ROSEBY, P. N. June 3, 1943, No. 8902. [Class 40 (i)] [Also in Group XXXIX] In a system for controlling over power circuits by means of alternating currents of a frequency high compared with that of the power currents and interrupted at characteristic rhythm frequencies, protection against parasitic currents is obtained by making the response to an operational signal dependent on the receipt of a preliminary signal having a different rhythm frequency. As shown, a relay R1 mechanically tuned to the rhythm of the preliminary signal connects up a thermostat TS, which in due course transfers the input circuit to relays R2, R3 tuned to respond to the operational signals, these relays remaining connected for a period determined by the adjustment of the thermostat. The twoposition contactor MLC controlled by relays R2, R3 may be replaced by a pair of thermostats co-operating with a switch blade subject to spring action to give a toggle effect. Specifications 518,877 and 562,986, [Group XXXIX], are referred to.

Abstract: 989,153. Root-crop harvesters. ROBERT H. CRAWFORD & SON Ltd. March 3, 1964, No. 8906/64. Heading A1F. A root-crop harvester comprises a share 18, an endless conveyer-chain 7 of linked parallel bars 8 on to the forward side of a run of which the excavated material is deposited, the run being arranged to travel transversely and along a path of rising gradient from the point at which the material is deposited so that the crop is tumbled, guards 21, 22 on each side of the chain-run, an opening in the front guard to permit the admission of the material to the chain and a laterally-offset opening in the rear guard to permit its discharge, the machine being mounted on tractor hitchlinks the upper one 34 of which is adjustable in length so that the fore-and-aft inclination of the belt may be adjusted to vary its screening effect. The harvesterframe 1, 2, 3, 4 is mounted on front wheels 38 about the axes of which it is tiltable upon adjusting the link 34. The belt is arranged around three sets of idlers 10, 11 and a guide 15 and is driven by a pair of spaced sprockets 12, 12<SP>1</SP> on a shaft 13 connected by a chain 29 to a sprocket driven by a power take-off 28. A guide 37 assists in funnelling the crop into a neat row behind the machine, while a detachable plate 36 prevents spillage of soil on to rows of previously-dug crop.

Title: Improvements in or relating to vibratory mechanism
IPC: B06B1/16
Filed: 1944-05-12
Abstract: .588,607. Vibratory mechanism. SQUARE GRIP REINFORCEMENT CO. (LONDON), Ltd., and GLEGG, G. L. May 12, 1944, No. 9135. [Class 80 (iv)] [Also in Group II] A vibratory mechanism comprises an inner member having a plurality of protuberances or rounded corners on its periphery and mounted loosely within a hollow member having a plurality of impact members relatively movably associated with its inner surface. Means is provided for producing relative rotary motion between the inner and outer members so that impacts between the protuberances and the impact members originate vibrations in the outer member. A rotor 11, having an end 14 formed with three lobes 15, is mounted within a cylindrical casing 16 having a steel lining 18 around which four rollers 17, Fig. 1, are equally spaced. The rollers 17 are supported for rotation between plates 19. When the rotor 11 is rotated repeated impacts occur between the lobes 15 and the rollers 17, and due to the repeated rebounding of the rotor after each impact about ten vibrational impulses may be produced per rotation of the rotor, and vibrational frequencies of approximately 60,000 impulses per minute may normally be obtained. Instead of the rollers 17, the impact members may consist of balls rotatably mounted in a cylindrical cradle. In an alternative construction the outer casing 16 may be rotated whilst the inner member 11 is maintained stationary.

A bracket for supporting a shelf 32 comprises an arm 11 pivotally connected to a support 10 for angular adjustment in a vertical plane, wherein one of the two parts, e.g. arm 11 or support 10, is provided with a fork, e.g. fingers 29, 30 on the arm 11, which embraces one of a series of projections on the other part, e.g. 21 to 25 on the support 10, thereby to lock the arm against pivotal movement, and the pivotal connection is such as to permit upward and outward movement of the free ends of the arm 11 to disengage the fork from the projections. The pivotal connection may comprise a headed stud 28 on the arm 11 which engages an inclined keyhole slot 26 (or 27), the stud being slidable in the slot from the base thereof in which position the fork engages a projection to the upper end 31 thereof in which position the fork and projection are disengaged to facilitate angular adjustment of the arm 11. Each slot 26, 27 has a corresponding series of projections one of which 23 is common. The support 10 is adjustably secured to a channel upright 16 by means of a bolt 18 extending through a hole 15 in an extension 14 of the support and engaging a nut 19 behind the side walls of a guideway 17 in the upright 16. Slots 34, 37 and holes 36 are provided in the arm to facilitate fixing of the shelf 32.

The chamber 10 is so dimensioned that fluid injected into it via a stationary pipe 11 generates a force greater than that of the spring 9 at a certain speed in order to open the slots. The piston may be made of reinforced plastics, e.g. a glass-fibre reinforced epoxy compound. The flange 6 of the piston carries a separated reinforced ring 14 to which is attached a rubber sealing gasket 15 which, as shown in Fig. 2, may form a bridge over the gap between the ring 14 and the motor part 2 and which is attached to the part 2. A bleed opening or nozzle 13 may be provided for the spring chamber 8. The spring may consist of a helical coil or of a plurality of disked spring washers or of disc-shaped elements. Alternatively, the spring may be speed-self-adjustable and may consist of stiff rings 17, e.g. of steel, Fig. 4, of triangular cross-section between which are disposed non- compressible elastic rings 18, e.g. of P.T.F.E.- coated rubber, which are progressively deformed with increased speed and force the rings 17 away from each other.

Abstract: 292,576. Etablissements Lyonnais Rochet-Schneider. June 24, 1927, [Convention date]. Spray carburettors.-In multicylinder engines wherein the cylinders are arranged in groups of two, three or more, each group being fed by a separate carburettor, the communication between the several groups of cylinders and the carburettors is such that when the engine speed reaches a predetermined value each carburettor is placed in communication with all the other groups of cylinders by automatic means. As an example, an engine comprises six cylinders arranged in two groups, the group 1-3 being normally fed by a carburettor C and the group 4-6 by a carburettor D. These carburettors open into a common passage A, B but are normally separated by a throttle valve P. At a predetermined speed the throttle is opened either by a mechanically actuated governor or by a link connected to a diaphragm subjected to the pressure of cooling water circulated by an engine-driven pump. The Specification as open to inspection under Sect. 91 (3) (a) states that the throttle may be actuated by hand, but this statement does not appear in the Specification as accepted.

Abstract: 137,450. Atkinson, J. S., and Powdered Fuel Plant Co. April 17, 1919. Pulverulent-fuel furnaces; fuel, feeding.-In connexion with the supply of powdered fuel by means of an air current produced by a fan such as 5, the admission of air to the fan is determined by a hit-and-miss valve or the like 9, the position of which is controlled in accordance with the load on the plant and the amount of fuel being supplied by the fuel-feed screw 2. This is effected by connexion of the valve to a governor device 12 driven from the motor 3, which drives the fan and the fuel-feed screw 2, and the speed of which in turn is controlled, by means not described, in accordance with the load on the plant. In a modification, the fuel may be supplied above the fan instead of at its centre, and, in both forms, there may be a secondary supply of air controlled like the primary air by a valve such as 15.
