Title: Improvements in or relating to Apparatus used in the Measurement of Water of Condensation, Boiler Feed Water and the like.
Inventor: LEA JAMES EDWARD
IPC: F22D11/00
Filed: 1916-04-04
Abstract: 104,061. Lea, J. E. April 4, 1916. Feed-water, supplying.-In a system in which water of condensation or boiler feed-water is measured by a V-notch or weir meter, and then discharged from the receiving-tank to a storage tank or to the boilers, means are provided to prevent aeration of the water. A pump d, Fig. 1, draws water by the pipe c from the catch-box a, and delivers it by the pipe e and three-way or Corliss-valve f either to the discharge pipe k or back to the catch-box. The valve f is controlled by the float i so as to maintain the waterlevel about 4 inches below the V-notch or weir, and thus prevent splashing and consequent aeration, and also to prevent the uncovering of the pipe c and admission of air to the pump As a further precaution, a baffle-plate o having openings at or near its lower corners may be provided. In a modification, Fig. 4, the water is discharged by gravity into a lower tank, and the outlet valve m is controlled by a float i to maintain a predetermined head in the catch-box.

Title: Bottle Washing Machines.
Inventor: THORNTON ALFRED AUGUSTUS
IPC: B08B9/32
Filed: 1916-04-05
Abstract: 102,866. Thornton, A. A., (Barry-Wehmiller Machinery Co.). April 5, 1916. Bottles, washing.-The bottles are mounted in open-ended radial holders in an intermittently rotated carrier and rest upon seats at the inner ends, which are moved during the time that the bottles are in the washing position to cause the presentation of different surfaces to the water jet. A crank-pin 21 carried by a main-operating shaft 19 enters, in turn, recesses 18<1> in a disk secured to the carrier A, which is loosely mounted upon a horizontal shaft 25, the whole being supported above a tank 1. Bottles are fed from the shelf 5 into the holders 4 of the carrier, and are removed at a lower shelf 6, each bottle resting upon a central seating member composed of a flat surface 26 and curved surfaces 27, 28 and secured to the central shaft 25, which is automatically oscillated by toothed gearing and link-work (not shown) driven from the operating-shaft. The combined effect of the two movements is to shake and turn the bottles about while in the vertical position shown, beneath the perforated spraying-rose 14 connected to a water-supply header 13 extending over the sets of bottles carried in each rotary section of the carrier.

Title: Speed sensor
IPC: F16H61/00
Filed: 1965-02-05
Abstract: 1,036,393. Valves. FORD MOTOR CO. Ltd. Feb. 5, 1965 [March 23, 1964], No. 5036/65. Heading F2V. [Also in Division G3] In a motor vehicle automatic transmission, a regulator valve 20 produces a high pressure signal by the action of the signal on a differential area of a valve member 26 opposing the action of a spring 40 and a low pressure signal when a device 68 responsive to the speed of a shaft causes a fluid pressure to oppose the spring. The device 68 comprises a centrifugal governor driven by toothed gearing from the output shaft 10 of a transmission and displaces a valve 44 to the right with increasing speed until ports 46 in the valve connect a bore 54 in the valve 26 with an exhaust port 48 in the valve housing. Pressure from an inlet pipe 34 acting on the right-hand end of the valve 26 is thus relieved so that the spring 40 displaces the valve 26 to the right to restrict communication between a regulated pressure outlet 32 and an exhaust port 38 and to increase communication with the inlet 34, the pressure increase in the outlet 32 causing the first gear shift. Further increase in speed causes the valve 44 to engage a shoulder 58 on the valve 26 so that the latter is directly actuated by the governor and causes a further increase in pressure initiating a second gear shift. The regulated pressure acting on the difference in area between lands 28 and 30 opposes opening movement of the valve 26. A gear 14 co-operates with a pawl on a parking brake.

Title: Improvements in or relating to time delay circuits
IPC: H03K17/288
Filed: 1946-02-19
Abstract: 614,472. Valve relay circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and PARKER, J. E. T. Feb. 19, 1946, No. 5100. [Class 40 (vi)] In a time delay circuit, a switching operation connects a charged condenser in the grid cathode circuit of a cold cathode discharge tube, and provides means for discharging and recharging the condenser in the opposite sense through a parallel connected resistance, such that the striking voltage of the tube is reached after a time delay. In the Figure, a potentiometer YJ, YK, YL, YM and YN is connected across the H.T. supply. Condenser C7 is charged through contacts DS1 and DS2, the upper plate being negative. Contacts DS1 and DS2 are controlled by relay DS (not shown) which is operated by the external switching operation. Contact DS1 connects the upper plate of the condenser to the control grid of cold cathode discharge tube NA, and contact DS2 disconnects the lower plate from the positive supply, which is then applied to the anode of tube NA. Condenser C7 now commences to discharge and then charge in the opposite direction, through the high resistance YP, YQ, YR; YS which is connected to a point on the potentiometer. After a time delay, the voltage on the upper plate of condenser C7 is sufficient to cause tube NA to conduct, and relay AL, which may control an alarm circuit, then operates. The effective value of resistance YP-YS may be adjusted by means of tapping 18, to provide a choice of delay periods, and fine adjustment, to cater, for example, for different cold cathode tubes, may be effected by means of the tapping 24 on the potentiometer. Element ARA which is a non-linear resistance material such as that known as " Atmite" '' (Registered Trade Mark), is provided to maintain the delay interval substantially constant in spite of changes in supply voltage. The resistance of ARA falls as the current through it increases, so that the proportional change in voltage across resistance YJ for any change in supply voltage is increased. The proportional change in the initial charge given to condenser C7 is therefore also increased. This results in a stabilization of the delay period. Specification 609,120, [Group XXXIX], is referred to.

Title: An automatic lathe
IPC: B23Q5/34
Filed: 1965-02-05
Abstract: 1,073,475. Automatic lathes. E. C. HAHN, [trading as INDEX - WERKE HAHN & TESSKY KOMM GES.]. Feb. 5, 1965 [Feb. 7, 1964], No. 5121/65. Heading B3T. An automatic turret lathe comprises a tool carriage 26 slidable on a bed 10, a tool turret 44 indexable by a Geneva mechanism 80, 84, a rack and quadrant 50, 54 actuated through a bell-crank lever 58 by a cam 66 to provide the working stroke to carriage 26, and a fluid pressure cylinder 18 for actuating the Geneva mechanism and also for providing a high-speed retraction of the carriage prior to the indexing. A shaft 42 carries drive pin 84 and also a crank 46 which is connected to rack 50 by a connecting rod 48. A pinion 36 is freely mounted on shaft 42 and can be connected thereto by a one-way clutch 86. The pinion co-operates with a rack 34 formed on cylinder 18. Fluid is supplied to cylinder 18 by a motor-driven pump 76 via a valve 74 which is actuated by lugs 68, 70, mounted on, or driven by shaft 64. In operation, starting from the position of Fig. 1 (not shown), a tool has just finished an operation. Lug 68 actuates valve 74; fluid is supplied to chamber 33, and cylinder 18 moves to the left. Rack 34 rotates pinion 36, and also crank 46, which exerts a pull on rack 50 through rod 48. Segment 54 however is against a stop 52a and therefore rack 50 cannot move to the left; and consequently carriage 26 moves rapidly to the right. Turret 44 is indexed, and during the second half of the revolution of pinion 36, pressure is exerted by crank 46 and rod 48 on rack 50, which urges lever 58 to turn in a clockwise direction. Such turning is howover blocked by roller 62 abutting cam 66; consequently carriage 26 is rapidly reciprocated to the left, up to the work. Roller 62 has now dropped on to the lowest point of the next cam lobe, and as the cam rotates so that the roller moves up the lobe, lever 58 is pivoted in the counter clockwise direction to this feed; the carriage through rack 50, rod 48, and crank 46 which are then aligned. In a modification, clutch 86 may be completely disengaged so that indexing of the turret does not occur, or the clutch may connect pinion 36 to shaft 42 so that the latter may rotate in opposite directions.

Abstract: 787,431. Engine starter drives. C.A.V., Ltd. Feb. 14, 1956 [Feb. 23, 1955], No. 5391/55. Class 7(5) [Also in Group XXXV] An engine starter drive comprises a rotatable input member b having axial freedom of movement relatively to a power source and having a quick pitch helix thereon a complementary sleeve on the input member a hollow output member g having thereon a pinion h for engagement with a toothed wheel i on the engine a friction clutch j interconnecting the sleeve and the output member and a spring located between the input and output members. Abutment s serves to actuate the switch q which controls an electromagnetically operable switch the latter serving to control the supply of current to the starter motor. The lever d has an elongated hole t. The thus provided lost motion is required to meet the condition that in the event of the pinion h being engaged with the wheel i when (through some accidental cause) the latter has become locked and consequently is immovable by the action of the motor on the pinion h the switch can re-open for bringing the motor to rest when the force on the lever is released. As shown a strong spring comprising one or more resilient washers n is located between an end plate of the clutch and a collar o and another spring is provided with its ends p supported on the input and output members. The interaction of the helices causes the plates of the clutch to tighten and the torque to be transmitted. After the engine has been started the mechanism is returned to its initial position by axial movement of the input member.
