Title: Improvements in and connected with means for clarifying liquids
IPC: B01D37/00
Filed: 1938-04-27
Abstract: 497,543. Clarifying liquids. WORSSAM & SON, Ltd., G. J., FOX, D. P. S., and ALFA-LAVAL CO., Ltd. April 27, 1938, No. 12569. [Class 23] [Also in Group I] A liquid-clarifying plant comprises a clarifier or filter and a source of pressure for maintaining pressure conditions in the plant, the source of pressure being controlled by an automatic control which is sensitive to pressure changes in the delivery from the plant. In the construction shown, a pipe e for supplying beer or other liquid under pressure is connected to a rotary or centrifugal pump f adapted to be driven by a motor g. The pump delivers liquid through a pipe e<1> to a centrifugal clarifier a which is connected to a filter press b. The outlet pipe t from the filter is connected by a pipe 1 to an automatic throttle device 2 fitted on a byepass connection 3 between the axial inlet and peripheral delivery of the pump f. The device 2, which has a projection 1a for attachment of the pipe ], is provided with a flexible diaphragm 4 engaged by a disc 5a on a vertical rod 5. The rod is adapted to be pressed downwardly by a spring 7 and is provided with rack teeth 5b engaging a pinion 9 on the shaft 10 of a throttle valve 11. The pressure of the spring 7 is adjustable by means of a handle 8a on a screw 8. Normally the valve 11 partly closes the byepass duct 14. If the pressure at the outlet of the fitter becomes reduced the spring 7 presses down the rod 5, thereby closing further the duct 14, so that the pressure of liquid by the pump f is increased. In the event of sudden back pressure in the pipe t the rod 5 is raised, whereby the throttle valve 11 is opened wide, so that the pressure produced by the pump f at the delivery side of the filter is reduced. Specification 443,732 is referred to.

Filed: 1923-05-10
Abstract: 197,686. Vacaresse, H. L. May 10, 1922, [Convention date]. Prisms and like elements, rotating.-In opticalprojection apparatus for the display of advertisements &c., transparencies 19 are mounted on a drum 20 which is rotated intermittently by a solenoid 1, and contains a vertically and horizontally adjustable lamp 21. The step-by-step actuation is effected by a spring-pawl on a bell-crank 25 pivoted at 26, Fig. 3, engaging a ratchet wheel on the drum shaft 22, the bell-crank 25 being connected to the core 2 of the solenoid 1. The drum 20 is positioned by a rim-indented wheel 35 on the shaft 22 engaged by a semi-circular boss on a spring 32 fixed at 33. The core 2 also operates a lever 6 fixed on a shaft 7 and having unidirectional engagement with a train of wheels a-h and a regulator 9. To the shaft 7 is fixed an arm 8, Figs. 3 and 6, carrying a spring- pressed contact 13 which, as the arm 8 is oscillated under the reciprocating action of the solenoid 1, makes electrical connection alternately with top and bottom contact-sectors 14<a>, 17. The contact 13 moves anti-clockwise, and in the position shown in Fig 6, the circuit is made via lead 42, arm 8, contacts 13, 14a, lead 43, solenoid 1, and lead 44. The core 2 is thus attracted quickly within the solenoid 1 until the contact 13 reaches the left-hand end of the contact 14<a> and drops to break the solenoid circuit, the drum 20 being also moved one step during this action. A spring 4 now withdraws the core 2, and contact is made with sector 17 to complete the lamp circuit, 42, 8, 13, 17. 45, 21, 46, 44. This withdrawal of the core is slowed down uniformly by the wheels a-h and during this action the picture is displayed. The apparatus may be mounted in a portable casing the front of which carries a ground glass screen.

Patent GB-734233-A (GB)
Title: Improvements in control arrangements for three-phase electric machines
IPC: H02P25/18
Filed: 1953-05-11
Abstract: 734,233. Control of A.C. motors. S.A.M.I. C.E.N. SOC. AZIONARIA MANTOVANA IMPRESE COSTRUZIONI E NAVIGAZIONE. May 11, 1953 [May 10, 1952], No. 13013/53. Class 38 (3). In a system of star-delta control for a threephase motor, actuation of a push-button 1 closes a line contactor T1 which has a selfmaintaining contact 5. A star-connection switch T3 also closes for starting the motor, whereupon the switch 1 is released so that switch 2 closes automatically. A relay S1, which is responsive to the motor current, opens contacts 10 to disconnect the switch T3 and to close the delta-connection switch T2. The closure of the delta switch is maintained through contacts 11 of a relay S2 which has one operating coil energized in accordance with the motor current and an auxiliary coil energized with intermittent current, so that, if the motor current falls below a predetermined value and remains below it, the contacts 11 are opened during one of the periodic interruptions of the energization of the auxiliary winding of the relay S2. The opening of the contacts 11 de-energizes the delta-switch T2 and energizes the switch T3 so that the motor returns to the star-connection. After the opening of a time-delay contact 13R the motor connections may again be changed from star to delta. The intermittent current for energizing the auxiliary coil of the relay S2 is derived from a transformer Tr through a mercury switch M1 periodically operated by a bimetallic strip B. A mercury switch M2 operates when the bimetallic strip reaches its maximum deflection to disconnect the heater R for the strip which thus alternates between two extreme positions. The transformer Tr is disconnected .when the star switch T3 is closed. In a modification, Fig. 2 (not shown), the relay for shifting the motor windings from delta to star connection is of the electromagnetic type in which the magnetic circuit is closed by a movable armature. The parts coming into contact are polished so as to present a gap as small as possible, thus preventing chattering.

Abstract: 647,808. Dashpots. KEARNEY, A. R., and ADAMS, Ltd., A. W. May 12, 1948, No. 13039. [Class 108(iii)] [Also in Group XXIX] A dashpot in a spring-loaded door-closer comprises a cylinder 1, Fig. 2, housing a plunger 2 and having a port 4 at its closed end communicating with the body 6 of a check valve. The body 6 is closed at one end by an adjustable head 12 having a fluted stem 13 carrying a slidable valve 15 engageable with a movable seat 8 urged by a spring 10 against a shoulder in the body to close a vent 9. On outward movement of the plunger 2, liquid is sucked in through the inlet 4a, lifts the valve 15 and then passes to the cylinder through the port 4. On inward movement of the plunger 2, the liquid is expelled from the cylinder 1 and slowly forced between the stem and the now seated valve. In the event of excessive pressure in the cylinder, both valve and seat are moved against the spring 10 to open the vent 9. The flutes in the stem 13 are radiused at their upper ends to permit adjustment of the area between the valve and stem. Specification 647,809, [Group XXV], is referred to.
