Title: Impeller-type drainage pump particularly for washing machines
IPC: D06F39/10
Filed: 1976-07-22
Abstract: 1526857 Filter PHILIPS GLOEILAMPENFABRIEKEN NV 22 July 1976 [25 July 1975] 30599/76 Heading BID [Also in Division F1] A pump, particularly for a washing machine, comprises a mushroom-shaped baffle 28 located in a chamber 3 which is separated from the pumping chamber 2 by a wall 4 provided with an opening 5 coaxial with the impeller 7, a suction pipe 20 and a discharge pipe 8 which are tangential or radial to the respective chambers being provided. The disc-like head 30 of the baffle 28 is of greater diameter than the opening 5 and its clearances from the chamber 3 and the wall 4 are such that it prevents the passage of solid objects which would be too large to pass through the discharge pipe 8, such objects being retained in the chamber 3 until an inspection cover 22 is removed. The shank 29 of the baffle 28 is fastened to the cover 22 or, as shown, the baffle is moulded integrally with a disc-like portion 24 of the core. The cover 22 comprises another disc-like portion 23, the two portions being squeezed together by a screw 25 to cause a gasket 27, as of soft rubber, to be expanded radially into sealing engagement with the wall of the chamber 3. The surface 31 of the baffle head 30 is formed in crosssection from a straight portion 31a and a quadrant 31b, while the opposite surface 32 is parallel in cross-section to the portion 31a. This facilitates a vortex-free flow of water. The chambers 2, 3 may be coaxial as shown or out of alignment, and may be of volate form instead of being cylindrical. As shown the pump may be of the type in which the impeller 7 is located to one side of the chamber 2 whereby it generates a vortex in the chamber which facilitates the expulsion through the discharge pipe 8 of small objects which are permitted to pass by the baffle 28. The impeller blades 33 project axially beyond the bounding plane Z of the impeller disc. An end cover 12 carrying a shaft seal 19 is clamped against a seal ring 14 by screws 15 and a disc 18, the latter also supporting the driving motor 11.

Title: Improvements in centrally controlled traffic signal arrangements
IPC: G08G1/081
Filed: 1961-08-25
Abstract: 994,418. Transistor circuits. SIEMENS & HALSKE A.G. Aug. 25, 1961 [Aug. 26, 1960], No. 30758/61. Addition to 994,417. Heading H3T. [Also in Division G4] In a centrally controlled traffic signalling system having programming units at both the central station and the individual intersections, the durations of some of the signal phases are controlled by pulse counting circuits, the count being initiated by control signals from the central station. As described a pulse unit Tv E , Tv Z , Fig. 1, feeds pulses, Fig. 2, on lines 0-9, 00-90 to a cross wire unit P providing outputs at predetermined times (0 sec. and 49 sees.) on wires 1, 2 and 3, 4 respectively. Assume initally relay B is actuated closing contact b1 to give a red signal. At time 0 sec. pulses occur on both lines 1 and 2 and transistor T1 conducts switching on transfluxor Tf1 allowing the 25 kc./s. generator G1 to pulse transistor T3 and actuate relay A giving a red and yellow indication. Contact a1 changes over producing a pulse which sets core K1 and switches on transformer Tf2 feeding 50 c./s. pulses to the counter chain Ft1 . . . Ft3 comprising two divide by five stages and one divide by six stage. After 150 pulses (i.e. 3 seconds) transistor T9 cuts off transfluxor Tf2 and samples core K1 to switch transistor T4 on briefly and switch off transfluxor Tf3. Transistor T6 is then cut off and relay B releases giving a green signal. At time 49 sees., pulses are fed to lines 3, 4 operating transistor T2 and switching off transfluxor Tf1 thus releasing relay A and giving a yellow signal. The release of relay A initiates a pulse from contact a1 to set core K2 and switch on transfluxor Tf2 starting another counting period so that after 3 seconds, transistor T9 operates again, sampling core K2 to switch on transistor T5. Transfluxor Tf3 is again actuated and transistor T6 is pulsed at 25 kc./s. from generator G2 to actuate relay B and give a red signal again. Fig. 4 (not shown) gives an alternative form of counter in which the yellow and red + yellow phases may be of different duration. In this counter, 1 sec. pulses are stepped along a three-stage counting chain, outputs being obtainable after 1, 2 or 3 seconds. An alternative cycle spit may be obtained by operating switches p1, p1<SP>1</SP>, p2, p2<SP>1</SP> to connect cross-wire board P<SP>1</SP>.

[Class 38 (v).] Excess current in the primary circuit h of a current transformer with losses causes an increase of current in the secondary winding i, this secondary current passing through and heating a forked bimetallic strip k which bends upwards and lifts a lever g out of latching engagement with a lever c which then moves in a counter-clockwise direction under the influence of a spring e which has been tensioned by the attraction of an armature b when the excess current developed. The movement of the lever c trips or moves contacts (not shown) into open position. When the current is thus cut off, the armature b is released and a spring f returns the lever c to its original position. A very great overload also causes instantaneous opening of the circuit by the attraction of an armature m which acts against an adjustable spring n<1> and strikes a pin g<1> on the lever g. The position of the bimetallic strip k is adjusted by rotating an eccentric l and the reluctance of the magnetic circuit is adjusted by rotating a soft iron vane o. In a modification (Fig. 8, not shown) the bimetallic strip acts on a system of levers to release the lever c.

Title: Improvements in carburettors
IPC: F02M5/02
Filed: 1926-12-08
Abstract: 279,011. Soc. Anon. la Co-operation Agricole et Industrielle. Oct. 12, 1926, [Convention date]. Spray carburettors.-In a carburettor comprising calibrated spraying orifices for normal and low speed running and separate corresponding diffusing devices where the emulsion is formed, said orifices being connected to the liquid entry orifices of the diffusers through comparatively long conduits, the calibrated orifices are in communication with the atmosphere and are disposed as near as possible to the axis of the float chamber. The float-chamber support 1 forms an integral casting with the body 3 containing the emulsion-forming devices, and the suction conduit 4, Fig. 1, is attached by bolts 5 to lugs 6 on the body, so that it may be adjusted about its axis to suit different connections for the throttle lever 8. The main nozzle 9 has a head 10 with orifices, 11 and coaxial therewith is a slow-running nozzle consisting of a tube 14 with flexible portion 15 adapted to be deflected by the throttle 7, as described in Specification 247,389. Emulsion is supplied to the main nozzle by a. diffuser 12 and to the slow-running nozzle by a diffuser 16, Fig. 3. The diffuser 12 is supplied with fuel through a nozzle 19 fed from the float chamber 2 through apertures 24, 20, the nozzle being carried at the lower end of a rod 21, as in Specification 241,853. The rod, according to the invention, is bored axially at 31 in order that the flow-producing head on the nozzle orifices 20 shall be merely that due to the height of fuel in the float chamber and remain constant under all inclinations of the carburettor. A similar remark applies to the nozzle 28 feeding the slow-running device. The emulsionforming air for both diffusers enters at 32, Figs. 3 and 4, and passes through channel 33 in communication with spaces 30, 34. The emulsion from the diffuser 12 which is fed to the annular chamber 9<1>, Fig. 1, may be corrected by air admitted through aperture 37 and passage 35 and controlled by a piston 36. The emulsion for the slow-running device may be corrected bv air admitted through apertures 38 adjustable by a valve 39, but still further correction air may be admitted through a passage 40 from an aperture 42 controlled by a. piston 41. According to the Specification as open to inspection under Sect. 91 (3) (a), the correcting pistons 36, 41 are adjustably secured to a lever 43 pivoted at 45, Fig. 4 (Cancelled), and actuated preferably by a temperature-sensitive device 46 - - 48 surrounded by heating fluid supplied from the motor to the space 51, Figs. 1 and 4. In a modification, Fig. 5 (not shown), a single piston may control the two air correction apertures 37, 42. This subject-matter does not appear in the Specification as accepted.
