Patent GB-1357659-A (GB)
Title: Implement in combination with a side draft control system
IPC: A01B63/10
Filed: 1972-05-17
Abstract: 1357659 Side draft control on agricultural implements DEERE & CO 17 May 1972 [17 May 1971] 23116/72 Headings AIB and A1P A draft control system is actuated by the lateral movement of an agricultural implement due to an imbalance of forces, and consequently permits fluid flow to a pair of hydraulic cylinders 62L and R associated with respective ground wheels 50 so that one side of the implement is raised/lowered whilst the other is simultaneously lowered/raised to thereby restore equilibrium. The average working depth of the tools mounted on the impliment is constant during the operation of the control system but can be varied, to meet requirements, by an auxiliary manually operated control valve. A tool carrying transverse frame 34 is mounted on a conventional three point linkage of a tractor 10, having drop links 32, and lower shaft links 18, and is further supported by ground wheels 50. The two cylinders 62L and R are in a hydraulic circuit (see Figs. 3 and 4, not shown) which includes a mechanically operated, spring centred, four-way hydraulic main control valve 104 and the tractor's pump arid reservoir. On either side of this main valve are two arms 122 pivoted at their upper ends to supports 120, and interconnected at their lower ends. The spindle of the valve 104 is connected to one of these arms and is therefore axially displaced from a spring maintained neutral position to a position in which fluid flows in the appropriate direction when one of the arms 122 pivots on contact by one of the lower links 18 due to lateral movement of the implement. The main valve 104 is by-passed by another four-way valve (see Figs. 3 and 4, not shown) which is connected into another hydraulic circuit between one of the cylinders and the tractor's fluid pump and reservoir. The average working depth of the tools is adjusted by manually actuating this valve which causes the working depth of the tools on the frame side, associated with the one cylinder to be altered whilst the working depth of the-tools on the other frame side is adjusted due to the follow-up action of the draft control.

Title: Improvements relating to means for determining the direction of rotation of synchronous electric motors
IPC: H02K7/118
Filed: 1937-08-24
Abstract: 491,403. Alternating-current motors. WALFORD, H. N. Aug. 24, 1937, No. 23142. [Class 35] For preventing rotation of a small synchronous motor in the wrong direction, a rotatable member c in gear connection with the rotor is carried in a manner to permit lateral movement so that the member can engage and be arrested by a stationary stop h when the motor turns in the wrong direction. The member c may be driven directly or through intermediate gearing from a gear wheel b on the motor shaft a and limited lateral movement is permitted by mounting its spindle d in elongated bearing apertures g. In a modification, the shaft of the wheel c is mounted in a balanced plate freely rotatable about the motor axis, movement of the plate in one direction being limited bv an abutment and in the other direction by stop which engages the teeth of the wheel and arrests the rotor.

Title: Liquid filter system
IPC: B01D37/00
Filed: 1959-07-06
Abstract: 850,919. Edge filters. FOXBORO CO. July 6, 1959 [July 10, 1958], No. 23167/59. Class 46. A filter, intended primarily for incorporation in a chlorinated-water flow line prior to addition of a chemical reagent for subsequent electrical sensing of chlorine content, has a single filtering aperture formed by the space between a conical body and a hollow conical part of a housing, the two being movable to vary the size of the space. Chlorinated water enters a housing 18 at 33 and flows between a plunger member 34, having a frusto-conical portion 37, and a frusto-conical opening 26 in the housing, solids being left in an annular opening 27. The member 34 is urged upwards by a spring 42 so that an upper frustoconical portion 36 is in contact with an upper frusto-conical surface 25 in the housing 18. Periodically the member 34 is depressed against the action of spring 42, to permit flushing of solids from opening 27 through the thuswidened filter gap in the filtering direction, by a timer-operated cam 50. Just prior to such depression a valve 30 is operated to connect outlet 29 with a drain 32 instead of flow line 31. In Fig. III (not shown), a pressure differential device between tappings from inlet and outlet pipes causes solenoid operation first of the valve 30 and then of the member 34.

Abstract: 423,954. Fluid - pressure brakes; pistons. WHITE, J. W., 18965, Muirland Avenue, Detroit, Michigan, U.S.A. Aug. 21, 1933, No. 23244. [Class 103 (i)] [See also Group XXVI] A hydraulic brakeoperating device comprises a flexible cup secured to a cylinder and having a dome-shaped portion which engages a piston and which is curved to a greater radius than its cylindrical wall. As shown, a pair of cylinders 15 are screwed into a member 14 secured, for example, to the back plate of an internal expanding brake. A pair of cups 22 of rubber or other flexible material have their edges 23 clamped between the cylinders 15 and an annular flange 24 on the member 14 and bear upon pistons 19 sliding in the cylinders 15. The pistons have projections 20 which pass through the ends of the cylinders 15 and abut on the heads 10<1> of adjusting screws 10 mounted in the upper ends of a pair of operating levers 5 pivoted at their lower ends on the back plate. These levers each carry a brake shoe. The member 14 has lugs 16, 17 projecting through the back plate 6 and one of these carries a fixing nut 18. Supply and bleed passages 25, 30 pass through these lugs and connect with an annular groove 27 in the member 14. To reduce the fluid capacity of the device a filler 28 of, for example, sheet steel is provided. The central portions of the cups 22 is of a flattened dome shape so that during the initial stage of an application, due to the tendency of the cups to assume a hemispherical form, the cups draw away from the cylinder walls and from the peripheral part of the pistons and then as the pressure increases stretch and again contact with the whole surface of the piston. A cushioning action is thus obtained.

Abstract: 600,016. Light valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 29, 1944, No. 23771. Convention date, Nov. 29, 1943. [Class 40 (iii)] A light valve consists of a cathode-ray tube 10 fitted with a screen 26 composed of two layers 31 and 32 of material, each of which has alternate light-obstructing and light-transmitting strips, mounted together so that the light-obstructing parts of one layer coincide with the light-transmitting parts of the other, the layer on the side on which the cathode ray impinges being of a material which is distortable upon the application of heat as shown in Fig. 5, thereby permitting the passage of light from a source 43 according to the degree of distortion varying with the strength of the cathode beam. This light-sensitive raster, which should be finer than the lines resulting from the scanning frequency, may be produced by photographic means in which gelatine is impregnated with a silver compound or may consist of a series of fine wires stretched on a suitable Frame. The screen may be made of cellulose acetate or nitrate, or gelatine, and may also have an interleaving diffusing layer of a material such as frosted mica. The resulting effect may be viewed direct by an observer or projected on to a screen. Provision for colour viewing or projection is made by means of a rotary colour filter placed between the light source 43 and the screen 26, and controlled by a synchronized generator. An alternative method uses separate light sources of different colours, the switching of which is controlled by a synchronized generator. By means of separate rheostats individual control of colours is obtained.
