Filed: 1966-08-16
Abstract: 1,093,016. Liquid filtering apparatus. G. ZWICKY. Aug. 16, 1966, No. 36531/66. Heading B1D. [Also in Division F2] The lower end of cylindrical filter 2 has a funnel 2b leading into a solids collecting tank 6, an inlet 11 opens into filter 2 and a filtrate reservoir with outlet 12 encloses filter 2 and tank 6, whereby solids fall from filter 2 into tank 6 and can be removed, after closing valve 8, without interrupting filtration. The filter removes metal from machine-tool coolant. In Fig. 1, tank 6 is accessible through a door in casing 10 and is decoupled at 7, after closing valve 8 in response to accoustic or visual signal produce as metal reaches magnetic pulse generator 9, and changed or emptied. A rotor 50-62 operated by a feed-liquid turbine 61 carries nylon brushes or rubber scrapers to clean the filter interior. The filter may be sintered bronze, granular material packed between concentric sieves or a paper element 13 supported by a sieve wall 2a and clamped therein by annular spring 14. Filter 2 and funnel 2b are removable together. In Fig. 2 (not shown) inlet (11a) enters a frusto-conical filter tangentially, to aid separation and filter cleaning, and tank (6') is fixed and has a lower outlet valve (20) as well as its upper inlet valve (22) from the filter. Valve (22) is normally held open by an immersed electromagnet (23), which is de-energised when metal reaches probe (27) to close valve (22). Additional valve (30) by-passes valve (22) so that pressures thereacross may be equalised before opening valve (22). Mechanical or electric interlocks may connect valves (20, 22, 30) to prevent more than one being open at once. Tank (6') has a drain outlet (34), covered by a sieve, whereby liquid is returned to dirty liquid reservoir (31) before opening valve (20). Compressed air may enter tank (6') at the top to sweep solids through valve (20). A pump may be located between reservoir (31) and the filter or on the downstream side of filtrate reservoir (1b#). Fig. 3 (not shown) illustrates a double valve replacing valves (22, 30), in which a manually or mechanically rotated cam (43a) lifts firstly a small central valve (44) then the main annular valve (22').

Abstract: 1,007,201. Delivering measured quantities of granular material. ALFA-LAVAL CO. Ltd. Sept. 18, 1964 [Sept. 18, 1963], Nos. 36732/63 and 27148/64. Heading B8N. [Also in Divisions F2 and H2] A control means for actuating a metering member 1 of a material delivery apparatus, such as described in Specification 903,997, comprises a pneumatically-operated piston 2 connected via a one-way drive R to the metering member 1 so that continuous movement of the piston effects intermittent movement of the metering member, a valve 4 for controlling the air pressure acting on the piston and actuated automatically for a predetermined number of times and a manually actuable means for initiating the operating cycle. The metering member may have four vanes defining four measuring chambers as disclosed in the above Specification; a sprocket 6 being secured rigidly to a shaft carried by the member. The piston 2 is mounted in a cylinder 3 and connected to one end of a chain 11, the other end being secured to a stationary member. A sprocket 9 runs on the chain and mounted on a link connected to a lever 7 freely pivoted on the shaft; a pawl 8 for engagement with the teeth of the ratchet is mounted on one end of the lever, the other end being loaded by a spring. In operation, upon pressing a button a switch MS1 is actuated to start an electrically driven timer adapted to periodically actuate a switch MS2 which energizes a solenoid to open the valve 4. The piston, which is then connected to a source of vacuum, rises and thereby, via the pawl and ratchet, rotates the metering member one quarter of a turn.

Filed: 1946-12-13
Abstract: 643,992. Master control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. Dec. 13, 1946, No. 36854. Convention date, Dec. 14, 1945. [Class 38(iii)] In a control system for a polyphase alternating current motor subject to overhauling loads means are provided to afford voltage unbalance in the primary winding to produce varying speed-torque characteristics when the motor is rotating under the influence of an overhauling load and additional means, acting jointly with the previous means, to afford, for selective spotting or checking of the load, another variation in the speed-torque characteristic such that at zero speed the motor exerts a substantial torque in the reverse direction to that in which the motor is urged by the overhauling load. Movement of the drum switch 11 to lowering position 1 effects connections with the auto-transformer T to energize the motor M in known manner to produce a small hoisting torque at zero. speed. Further movement of the drum to lowering position 2 inserts a resistor r in the motor circuit so effecting phase shift in known manner to reverse the motor torque at zero speed. Moreover the primary circuit of the transformer 51 is interrupted thus allowing the relay winding 44a to be energized by transformer 52. Subsequent movement of the drum backwards to spotting postion IS will now produce the high hoisting torque required for spotting or checking,the load since the motor connection is now moved from tap 30 to a higher voltage tap 39 on the auto-transformer due to the operation of relay 44 and the electromagnetic switch 40. Relay 44 is so calibrated that when the motor speed is reduced to a predetermined value during spotting the relay de-energizes thus de-energizing the main switch and causing the application of a magnetic brake B. In Fig. 1 the switch contacts 41, 42 must handle the motor current but in the embodiment illustrated in Fig. 3 a hand or foot operated switch 68 has been substituted therefore which is only required to handle the primary current of a transformer 72. In the embodiment according to Fig. 3 the drum operates to connect the primary windings 71a, 71b across lines L<SP>3</SP> and L' or L<SP>2</SP> respectively so that the voltage of the secondary winding 73 is in phase or 120 degrees out of phase with that of the auto-transformer T thus producing corresponding control arrangements to those obtained in Fig. 1.
