Title: Improvements in and relating to variable discharge control means for hoppers or likestorage means
Inventor: ATKINS JOHN HARRY CLAPHAM
IPC: B65G47/00
Filed: 1959-11-30
Abstract: 931,002. Hopper discharge. BAKER PERKINS HOLDINGS Ltd. Nov. 25, 1960 [Nov. 30, 1959], No. 34158/62. Divided out of 931,001. Class 78 (1). Variable discharge control means from a hopper 2, having an open bottom closed off by a movable conveyer band 3, comprises two gates 50, 51 which may be raised and lowered, of which the gate 50 has a slot 52 and the gate 51 overlies the gate 50, whereby coarse adjustment of the discharge rate from the hopper is effected by moving the two gates together and fine adjustment by moving the gate 51 relatively to the gate 50. The gates 50, 51 are mounted on pairs of arms 53, 54 which swing about a common pivot and cams 56, 57 are positioned to act on the arms and raise and lower the gates. The cams 57 which act on the arms 54 and raise and lower the gate 51 are secured to a shaft 58 and the cams 56 which act on the arms 53 and raise and lower the gate 50 are freely rotatable on the shaft 58. Considering the cams on one side only, Fig. 5, the cam 56 has an arcuate slot 60 and the cam 57 has a projecting pin 59 which passes through the slot 60. The shaft 58 is driven in one direction through an electromagnetic clutch 62 and in the other direction through an electromagnetic clutch 63. The clutches are controlled by means sensitive to variations of the weight of material from a given weight. On a signal being sent to one or other of the clutches 62, 63 the cam-shaft 58 is rotated to cause the cams 57 to raise or lower the gate 51 till its lower edge coincides with the upper or lower edge of the slot 52 in the gate 50. If the desired weight of material is not then achieved the cams 57 start to rotate the cams 56 and the gate 50 moves in the same direction as the gate 51 to increase the rate of correction of the feed. On reaching a point where the weight is slightly exceeded the clutch is disengaged and the other clutch is engaged, the shaft 58 thus being rotated in the opposite direction, with the result that the gate 51 moves in the opposite direction while the gate 50 remains stationary, the desired output being achieved by final operation of the gate 51 only.

Abstract: 1318161 Valves; anti-skid systems FIAT SpA 21 July 1971 [28 April 1971] 34237/71 Headings F2F and F2V An electrically-actuated valve has a spring- loaded closure member 25 with a restriction 32 therethrough movable against a seat 20 between an inlet 12 and outlet 22 by a spring- loaded armature 42 of a solenoid 46 which armature also closes the restriction. After deenergization of the solenoid the closure member 25 remains seated due to inlet pressure acting thereon until the outlet pressure rises sufficiently to unseat it. In use the valve 10 is connected between a vehicle-driven pump 50 and a wheel cylinder 78 of a disc brake in an antiskid system. A pedal-operated valve 58 controls the return to reservoir 52 and thus the inlet pressure to valve 10 which has a solenoid operated valve 70 connected between it and the wheel cylinder. Both valves 10, 70 are actuated by an anti-skid speed sensor 90. Valve 70 allows a gradual release of pressure in cylinder 78 while restriction 32 allows a gradual pressure build-up therein.

Title: Control mechanism for motor vehicle power transmission gearing
IPC: B60K17/08
Filed: 1935-10-03
Abstract: 463,682. Controlling change speed gearing. GENERAL MOTORS CORPORATION. Oct. 3, 1935, No. 34531/36. Convention date, Oct. 8, 1934. Divided out of 463,643. [Class 80 (ii)] Control mechanism for step-wise change-speed gearing for vehicles comprises a speed-responsive device with three phases of action, below a critical engine or vehicle speed ensuring a low ratio, above another critical speed ensuring a high ratio, and intermediate these speeds operating conjointly with the accelerator to determine the ratio. A floating lever 166 controls the valve 140 of a speed-changing servomotor 138 and one fulcrum 169 of this lever is controlled by the speed-responsive device or governor 211, and the other fulcrum 175 by the accelerator 258, Fig. 1 (not shown). In the arrangement shown, there is a second or manual change-speed unit (not shown) with a servomotor controlled by a second valve 140<1>, a passage 143<1> leading to this second servomotor, all as described in Specification 463,643. The piston 150 shown is an ac. cumulator for oil pumped by the engine and entering at 136 The governor 211 through a bellcrank 172 and a link 170 con trols the position of the governor fulcrum 169 influencing the valve 140, which is shown in its extreme position at right closing a feed duct 143 so that the servo motor 138 is not operated anc the automatic change - speec unit is in high ratio. The valve 140 is operated by a toggle 157, 158, the fixed fulcrum of which is at 156. The governor 211 is driven from any shaft such as the engine shaft or the propeller shaft. At low speeds, the weights 211 are collapsed and the fulcrum 169 is at right at 169<1>. The accelerator is geared to a shaft 173 so that depression moves the fulcrum crank-pin 175 left of Fig. 14. Extreme release of the accelerator moves the pin 175 to a point 175<1> not too far to the right. The rightward displacement of the joint 169 by the collapsed governor robates the floating lever 166 anticlockwise about the pivot 175<1> so that the toggle 158 is snapped left over the pivot 156 by its spring 160 against a control spring 164 so that the valve 140 is shot left to open position, which moves the servomotor 138 to bring in reduced speed in the automatic transmission unit. This is the first or low-speed characteristic phase. Then when the governor 211 is open wide, the joint 169 is pulled left so as to lift the floating lever 166 off the accelerator fulcrum 175, with the result that the control spring 164 holds the toggle 158 and the valve 140 hard at right, as shown, in the closed position. The servomotor 138 is then held out of action, with the automatic transmission unit in high-speed characteristic phase. Then there is a middle phase between certain speeds when the governor is partly expanded so that the governor fulcrum 169 and the accelerator fulcrum 175 are operative conjointly on the floating lever 166, and therefore on the valve 140 and on the speed ratio. Specification 463,683 also is referred to.

Title: Improvements in or relating to breathing apparatus for swimmers
IPC: B63C11/16
Filed: 1957-11-06
Abstract: 822,680. Respiratory appliances. GIRDEN, B. B. Nov. 6, 1957, No. 34558/57. Class 81 (2). A breathing tube for swimmers has a floatactuated balanced closure valve, so that it will not tend to be opened by pressure within the mouthpiece or mask. The type of valve preferred is a balanced butterfly valve 23, Fig. 3, mounted on a spindle 24 so that it can be closed by a float 27 on an arm 28, when the float tends to rise. Semicircular seatings 25, 26 are provided in the tube 12 for engagement by the vane 23 and the top of the tube carries a shroud 13 to prevent water splashing into it. The lower end of the tube 12 leads into a mouthpiece 11, Fig. 2, held on the user's head by a strap 29 and, in the form shown, the mouthpiece also communicates with an inflatable bladder 17, which serves as a rebreathing bag, so that the user can exhale and inhale instead of holding the breath continuously. A flap valve 19 is fitted at the bottom of the bladder so that water can be blown out when the user is at the surface. In a modified form, separate inlet and outlet tubes are used, the former communicating with the nose and the latter with the mouth. In this case the float-actuated valve is mounted in an outlet common to the two tubes so that, when closed, it prevents water entering the tubes but, at the same time, leaves a communicating space between them. If a bladder is fitted to the mouthpiece in this form it is inflated from the mouthpiece and air is withdrawn from it to the inlet tube through the outlet tube and communicating space. A third form of the apparatus has a mask fitted over the eyes and nose only but has a separate mouthpiece connected as in the foregoing embodiment.

Filed: 1927-12-23
Abstract: 306,235. Whidbourne, H. Dec. 23, 1927. Levels, regulating.-Mechanism for driving apparatus at constant speed comprises a hydraulic turbine and a supply reservoir, the head of liquid in which is kept constant; the liquid may be paraffin. The turbine 1 is fed from a reservoir 2 containing a strainer 19 by a pipe 3, the spent liquid passing into a tank 5 from which it is returned to the reservoir 2 by a pump 6 driven bv an electric motor 7. The liquid level in the reservoir 2 is kept constant by an adjustable overflow 10 which is set by a hand-wheel 24, or by a thermostat, or by a clock which varies the head of liquid when the turbine is' running too fast or too slow. Fig. 7 shows mechanism, controlled by a clock, for regulating the head of liquid. The overflow 10 is set by a ratchetwheel 49 which is actuated in one direction or the other by a clock-driven cam 44 through levers 46, 47. The direction in which it is moved is determined by the position of a double plate 56 pivoted at 57. The plate 56 is actuated by balls dropped into a chute 28 when a pivoted carrier 32 is rocked by a lever 30 which is actuated by a clock-operated cam 29. An arm 26 carrying a knife edge is rotated by the turbine, and the arrangement is such that, if the turbine is in time with the clock, the dropped balls pass to a chute 41 and do not influence the setting gear, but if the turbine is out of time, the balls fall upon one or other side of the plate 56, and set the ratchet-gear 46, 49 for actuation. A conveyer 35 takes the balls back to the carrier 32. Specification 189,266, [Class 40 (v), Wireless signalling &c.is referred to.
