Patent GB-856660-A (GB)
Title: New or improved agricultural machine
Inventor: WILLIAMS FREDERICK
IPC: A01D43/07
Filed: 1958-05-03
Abstract: 856,660. Agricultural implements. HARRISON, McGREGOR & GUEST Ltd. April 22, 1959 [May 3, 1958], No. 14186/58. Classes 6(1) and 6(3). [Also in Group XXX] An agricultural machine comprises a load carrying body 26 provided with an endless conveyer 51 for moving a load rearwardly to an open end of the body, flails 39 mounted in a transverse shaft 37 carried by arms 33 adjusted by hydraulic jacks 43 and a deflector 92 adjustable about the shaft 37. A delivery shoot 94 may be positioned over the flails and is provided with rollers 95 which run on the upper edge of the side walls of the body. The shoot 94 may be retained in an inoperative position as shown in Fig. 3. An adjustable land wheel 44 is mounted at one side of the flails 39. Rotary tines are mounted on a shaft 72 and rotate so that at the lowest point of travel they move away from the open end of the body. For cutting and loading silage the shoot 94 is engaged over the flails and the deflector 92 is secured in the position shown in full-lines in Fig. 1. The flail assembly is lowered to the ground to a position determined by the setting of the wheel 44. The drive to the conveyer is disconnected and as the machine is towed forwardly the flails cut the crop and project it up the shoot 94. For loading manure the shoot is engaged with the flail assembly 1 and the deflector 92 is positioned as shown in dotted lines in Fig. 1. The conveyer is again stationary and the arms 33 are raised so that the flails engage the top of the manure heap. The machine is reversed and the flails pick up manure and project it up the shoot 94. To spread manure the shoot is locked in the position shown in Fig. 3, the deflector being positioned at the lower front side of the flail cylinder. The conveyer moves manure rearwardly to the flails the current reaching the flails being regulated by the rotary tines on the shaft 72.

Title: Improvements in mountings for television tubes
IPC: H04N5/645
Filed: 1952-09-05
Abstract: 775,442. Television. PALLEMAERTS, J. E. H. Dec. 7, 1953 [Sept. 5, 1952], No. 14201/52. Class 40 (3). A television camera tube and a picture reproducing tube are mounted end-to-end in a cylindrical container the portion containing one tube being rotatable coaxially with respect to the portion containing the other tube. As shown in Fig. 1 and Fig. 1 (contd.) the camera tube supported by socket 28 and base 26 is mounted inside a first portion 24 of the cylindrical container and the picture tube supported by socket 44 secured to a cylindrical core 36 is carried by a second portion 45 of the cylindrical container rotatably attached to portion 24 by means of a ball-race 38. The camera tube end of the container is closed by means of an optical system comprising an apochromatic lens 11 (the focusing of which is controlled by means of a cable 12 passing through the optical system support 1 by a rubber grommet 13) a concave mirror 6 and an adjustable convex mirror 20 and the picture reproducing tube end is closed by means of a glass or plastic window 51 and a mark 53 which provides a rectangular viewing frame. The whole assembly is positioned in an outer casing (shown by dotted lines in Fig. 2) and supported by means of inflatable tubes 29, 30 attached to flanges 23, 25, thus providing a water-tight enclosure in sections (A, B, C, Fig. 2) of which the various circuit components concerned with the operation of the tubes may be supported. Electrical connection between the inside of the container 24 and the circuit components is effected by means of sockets 59 co-operating with plugs 58 and between the components in the various sections by means of connections 60, 61. The apparatus is intended to be employed for viewing objects where direct visual observation is impossible, e.g. wrecks submerged at great depths and lying at various angles, and in this case, by rotation of the picture tube end of the assembly, the image may be viewed in an upright position. Radiations outside the visible region of the spectrum may be employed to form the image on the camera tube and for this purpose the lens 11 is made apochromatic for suitable lines in the visible, ultra-violet and infra-red regions of the spectrum. Specification 775,441, [Group XXI], is referred to in the Provisional Specification.
Patent GB-199711-A (GB)
Title: Improvements in or relating to milking machines
IPC: A01J5/10
Filed: 1923-05-30
Abstract: 199,711. Ridd Co., Ltd., (Assignees of Ridd, A.). June 20, 1922, [Convention date]. Releasing - gears. -The pulsator of a milking - machine comprises opposed cylinders 10 accommodating a pair of pistons 11 connected by a rigid rod 12. The cylinders, which are open to the atmosphere at their inner ends, are mounted on a frame 13 that can be fitted to the lid 14 of a milk pail or arranged in the pipe line of a milking system. Ports 25 at the outer ends of the cylinders are connected by pipes 31 with regulating cocks 32 to ports in the seat of a slidevalve 28 by which the cylinders are alternately put in communication with the milk pail or a. source of vacuum and the outer air respectively, the one cylinder being connected up to the vacuum when the other is open to the air. The valve is provided with upwardly-extending flanges 33 adapted to be engaged by the end of a spring arm 36 adjustably fitted on the piston rod 12. As the pistons move this arm is held back for some time by engaging an adjustable stop 37; on snapping past the stop the arm strikes the valve and forces it to its extreme position on that side. Adjustable stops 34 limit the movement of the valve. The valve 28 may be arranged to oscillate about a pivot. An arm 24 projecting from the piston rod on the other side actuates a slide valve 17 by which pipes 20 leading to the outer chambers of teat-cups are alternately put into com. munication with the source of vacuum and the outer air.
Patent GB-363605-A (GB)
Title: Improvements in or relating to sending and receiving synchronised systems for television, telecinematography, telemechanical devices and other applications
IPC: H04N5/16
Filed: 1931-05-14
Abstract: 363,605. Synchronous movements. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, Seine, France. May 14, 1931, No. 14291. Convention date, May 21, 1930. [Classes 40 (iii) and 40 (v).] Synchronizing signals are impressed on a carrier wave so as to alter its amplitude in a direction opposite to that produced by tele. graph, television or similar signals, Fig. 5, (not shown). Television signals are applied across a resistance R, Fig. 1, in the grid circuit of an oscillating valve 0 so as to reduce the amplitude of the current supplied to an aerial K. A commutator I on the transmitter shaft breaks the circuit of the primary P of a transformer in the plate circuit of the valve to produce a synchronizing signal of increased current in the aerial. At the receiver the voltage drop in a resistance p, Fig. 2, in the plate circuit of a detecting valve, produced by the signals, is opposed to a battery P, and in the case of the synchronizing signal is sufficiently low to permit a discharge through a neon tube L, which is in circuit with a resistance D and condenser V with values such that the natural period of the relaxation oscillation is equal to that of the synchronizing signal, as described in Specification 350,443. The synchronizing signals may be separated by a valve so biased that it does not respond to the television signals, Fig. 6 (not shown). The grid bias battery may connect the grid to a coupling resistance, Fig. 3 (not shown), or be in series with a resistance across which the signals are applied to the grid, Fig. 4 (not shown). To counteract fading, the grid bias of the valve 4, Fig. 7, responsive only to the synchronizing signals, is obtained from a resistance R, shunted by a large condenser C, in the circuit of a rectifying valve V fed from the amplified television signals through a transformer T. Alternatively the anode current of the selecting valve itself provides the grid bias by means of a resistance and condenser acting as a filter, or by several such filters in series, between the cathode and a point common to the grid and plate circuits, Fig. 8 (not shown). The valve may be indirectly heated so that the cathode can be given any desired potential. Specifications 356,506 and 356,637 also are referred to.
