Title: Fluid flow control mechanism particularly for washing machines
IPC: B08B9/28
Filed: 1948-04-01
Abstract: 654,590. Washing bottles. COZZOLI, F. J. April 1, 1948, No. 9262. Convention date, April 3,1947. [Class 138(i)] [Also in Group XXIX] In a machine in which containers are washed by jets of fluid at various stations, the fluid is controlled by a valve 20 having a member with a stem portion 22 slidable in a bore in the casing 21 and a head portion 22a located in a fluid chamber 21a and co-operating with a seat 21b therein, the stem having a fluid conduit 22d terminating adjacent the head, so that it is closed by the wall of the bore when the head contacts the seat. Carriers 10 with the containers a on the jet tubes 17 are carried on an endless chain 11 mounted on sprocket wheels 12 and are indexed through various processing stations with a dwell period at each. During each dwell period, the cam 38 raises the plunger 35 which moves the crank 33 to shift the valve bodily forward until the rounded end 22f of the stem contacts the conical seat 19 on a carrier. The stem moves into the casing against the spring 24 so that fluid passes from the flexible tube 26, through the valve and coupling 19, 22f, and the carrier conduit 18 to the jet tubes. The casing is a loose fit in its support in order to achieve good seating at the coupling.

Abstract: 112,239. Harsch, C. A. June 28, 1917. Wire.-A cable for closing the circuit of an electric fire-alarm comprises a core 21, Fig. 9, of fusible metal partially surrounded by a conductor 11 of hard metal and divided into a series of cells by means of grooves 40.

[Also in Division D2] Tobacco smoke filters, e.g. for cigarettes, are made by passing a continuous web of paper, e.g. of the semi-crepe absorbent type, over a roller wetted with an aqueous solution of sodium or potassium carbonate whereby the paper becomes evenly and thoroughly impregnated with the solution, crimping the impregnated paper and forming it into filter rods. Preferably the impregnated paper is dried to a moisture content of 11 per cent prior to crimping. The aqueous solution may contain up to 30 gms. of solid carbonate per 100 ml of water to provide a filter rod having up to 19 per cent by weight of carbonate, but the preferred ranges are 15-20 gms and 10-14 per cent respectively.

Abstract: 980,897. Light modulators. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 8, 1963 [March 10, 1962], No. 9412/63. Heading H4F. A deformation wave propagated across piezooptic bi-refringent layer 4 disposed between crossed polarizing plates 1 and 2 permits light from a source behind plate 1 to be transmitted through plate 2 due to rotation in the layer of the direction of polarization in the region of the wave front. By propagating a succession of such waves a series of transmissive regions may be caused to progress across the device and patterns or a raster may be formed on a further polarizing plate 3 whose direction is parallel to that of plate 1 by propagating further waves across a second piezo-optic layer 5 situated between plates 2 and 3. The deformation waves may be produced by magnetostrictive means or the layers 4 and 5 may be piezo-electric and energized from electrodes 9 and 10, respectively.

Abstract: 753,892. Rectifying. AKT.-GES. BROWN, BOVERI & CIE. April 1, 1954 [April 1, 1953], No. 9555/54. Class 38 (2). To prevent reverse current flow in a polyphase mechanical contact rectifier under disturbed conditions, the circuit is so arranged that while the output characteristic is only slightly inclined at full load, there is a sudden rise in the output volts as no load is approached. This may be achieved by a supply transformer arrangement which includes an interphase transformer. For rectifying a three-phase supply to supply a D.C. line g, the supply transformer may comprise three single-phase secondary windings c, d, e with ends connected to contacts k1-k6 through switching chokes f1- f6, the centre taps of the secondary windings being connected to the zig-zag wound interphase transformer h.

Abstract: 1,249,056. Tumbling. I. OHNO. 24 Feb., 1969, No. 9810/69. Heading B3D. Tumbling apparatus comprises a rotary drum on which are mounted cylindrical or polygonal containers each on a rotatable shaft parallel to the drum shaft, the cylindrical axis of each container being inclined to its shaft. The arrangement is such that the material being treated and the abrasive move in a figure eight path within the containers during drum rotation and rotation of the containers relative to the drum. A drum comprises discs 4, 5 connected by a shaft 6 rotatable on a shaft 2 fixed to a base 1. A motor 8 drives, through a belt 10, a pulley 7 fixed to the disc 4 to rotate the drum, e.g. at 200 r.p.m. Four containers 12, having openings closed by lids 13, are rotatably mounted in the drum by shafts 11 parallel to the shaft 2; the axes of the containers are inclined to the axes of the shafts 11. Gears 14 fixed to the shafts 11 mesh with gears 15 journalled on the disc 5 and meshing with a gear (16) fixed to a shaft 24 journalled on the shaft 2. A forked member 17 supported by a pin 18 surrounds the shaft 24, rotation of the latter being prevented when the member 17 is closed by a screwthreaded rod 19 operated by a handle 21; the containers 12 will then rotate relative to the drum oppositely to the direction of rotation of the drum and with the same angular velocity if the gears 14, 15, 16 are all of the same diameter. Due to centrifugal force resulting from rotation of the drum, the container contents travel round the container as shown at s, and travel axially of the container as shown at t.

Title: Voltage regulator system for polyphase dynamoelectric machines
IPC: H02P9/32
Filed: 1960-03-21
Abstract: 896,427. Automatic voltage-control systems. WESTINGHOUSE ELECTRIC CORPORATION. March 21, 1960 [March 27, 1959], No. 9848/60. Class 38 (4). In a system in which the field excitation of a polyphase dynamo-electric machine is automatically regulated to keep the average of the output phase voltages constant, increase in excitation is prevented if unbalance of the output phase voltages exceeds a predetermined value. In Fig. 1 current is supplied to the field 12 of a threephase synchronous alternator 10 by a D.C. exciter 28, the field 24 of which is energized through a three-phase magnetic amplifier 60 and rectifiers 202-212 from the combined outputs of a voltage transformer 70 and current transformers 66 associated with the alternator output. Normally the three-phase alternator output voltage is applied through rectifiers 42 and an electronic or Zener diode bridge 50 to control magnetic amplifier windings 170-180 and thus maintain the average or positive phase sequence alternator voltage constant at a value determined by the setting of a rheostat 44. Biasing windings 182-192 of the magnetic amplifier are energized from the alternator output through a rectifier 90. Rate feed-back is applied from a winding 22, inductively coupled to field winding 24, to windings 144-154 of the magnetic amplifier. Unbalance of the three-phase alternator output under fault conditions causes a negative phase sequence network 334 to produce a corresponding output voltage which, if large enough, is effective through a rectifier 310 to render a Zener or other diode 306 conductive and energize magnetic amplifier windings 156- 166 so that excessive rise of voltage, which would otherwise be produced by the automatic voltage regulation, is prevented. Excitation of field winding 24 in dependence on the alternator output voltage provides some automatic regulation even apart from that through rectifiers 42, while excitation in dependence on alternator current ensures a certain minimum excitation under fault conditions. The alternator output and that of a second alternator, controlled in a similar manner and represented by block 350, are connected to bus-bars B 1 , B 2 , B 3 . Equal load division between the two alternators is ensured by interconnected current transformers, such as 26, which correct inequalities by modifying the input to rectifiers 42 through transformers such as 93. The Specification refers to (a) application to self-excited alternators and tap-changing transformers; (b) introduction of zero phase sequence control voltages; (c) use of electronic or transistor amplifiers in place of the magnetic amplifier.
