Filed: 1930-11-27
Abstract: 367,475. Metallic-vapour apparatus. JAC*KSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Siemens-Schuckertwerke Akt.-Ges. ; Siemensstadt, Berlin.) Nov. 27, 1930, No. 35754. [Class 39 (i).] A body 2, Fig. 1, inserted in the liquid electrode 1 to act as a terminal point for the arc, is constructed so as to draw up liquid therefrom by capillary action and extends above the electrode a distance sufficient to prevent the development of excess vapour. The body consists of steel, copper, platinum or tungsten wires 7, Fig. 2, held together by a quartz or porcelain sleeve 8. The body may be twisted so that the liquid is drawn up along a spiral path. A cooling medium may be circulated through hollow wires. In a modification, the body may comprise a wick 10, Fig. 3, which surrounds a tungsten core 9 and is protected by a tantalum sleeve 11 and a plate 13. The capillary action may be increased by grooving the body or by forming it with a spongy surface or with pores. For example, the body may be coated or alloyed with a metal which amalgamates with mercury. Tin and gold are suitable coatings, and the metals tin, zinc, gold, platinum and copper may be components of the alloy. The mercury cathode 1 of a rectifier is protected by a screen 3 in which holes may be provided to facilitate the return of condensate to the cathode; a cooling medium may be circulated through it. Starting may be effected by a movable electrode 18, or by making the body 2 as a float which is adapted to be moved against a stationary electrode, or by depositing mercury on the body. The Specification as open to inspection under Sect. 91 (3) (a) states also that the body may comprise wires having different coefficients of expansion. This subject-matter does not appear in the Specification as accepted.

Filed: 1964-09-03
Abstract: 1,057,575. Textile treating apparatus. G. TIGGES. Sept. 3, 1964 [Sept. 19, 1963; Nov. 7, 1963], No. 36132/64. Heading D1L. In apparatus for ejecting a carrier tube from an axial aperture in a yarn spool and introducing a lap carrier into the aperture by means of a mandrel extending through the aperture and being movable axially of the yarn spool which is carried by a support table, a plurality of vertically movable mandrels extend through apertures in the table which is arranged to be moved stepwise, and are mounted on the table, each mandrel having a raised position below a carrier tube ejector shoot and arranged to be maintained in such position until by virtue of movement of the table, the mandrel reaches a lap carrier loading position at which the mandrel descends together with the lap carrier which is centred by the mandrel relative to the aperture. In one embodiment the various steps are performed automatically on a table 1 which rotates so that a lap is initially positioned at one station A (Fig. 2, not shown), rotation of the table brings it first to a station B where the rising mandrel 4 ejects the tube on which the lap has been wound, then to a station E where the lap carrier 10' is inserted into the mandrel by clamp means 24 (Fig. 5, not shown), and then, after the mandrel has been withdrawn and the carrier positioned in the lap, to a station H where the lap is removed from the table. The carrier may have feet like portions 31 to retain it in the lap. In a further embodiment rigid lap carriers in the form of conical perforated sheet-metal tubes, can be inserted into laps with the aid of a guiding mandrel from below and a pushing member from above.

Title: Formation of branched pipes from temporarily plastic materials
IPC: B28B21/74
Filed: 1976-09-01
Abstract: 1534610 Producing branched pipes W A CLARK 1 Sept 1976 [18 Nov 1975] 36174/76 Heading B5A A branched tube 2 (Y, T or inspection junction) is produced by placing a slug of plastic material (clay, concrete or thermoplastics) in a split mould 1 defining the outer shape of the tube, introducing opposing plungers 10/11 into the slug to shape the main cavity 3 and force excess material into a branch piece 6, and then introducing a hollow plunger 30 to shape the branch cavity 33. The split mould is hinged and held together by toggle clamps (see Figs. 7/8, not reproduced). Each plunger 10/11 comprises metal discs 12/14 sandwiching an oiled felt disc 13. As each plunger moves against the plastic material, the felt expands radially so that the bodies of the plungers do not contact the material, while air escapes through the felt. The plunger 10 is preferably placed in a position 61 while plunger 11 moves to a position 62, where it is then met by plunger 10. Overshooting of position 62 is effected. Before or after withdrawal of plungers 10/11, plunger 30 cuts a core of material using an oversize knife edge 36, the core passing through the plunger hollow 42 with little friction (as it is undersized by edge 36) into a cage 43, where it expels any core present from a previous moulding.

Title: Improvements relating to windscreen wipers
IPC: B60S1/18
Filed: 1935-09-13
Abstract: 462,651. Wind screen'- cleaners. HANNING, A. H. Sept. 13, 1935, No. 36639/34. [Class 138 (i)] [Also in Group XXIV] In driving mechanism for moving a wiper for windscreens and the like to-and-fro across the screen by means of a rotating screwed spindle alternately clutched to oppositely-rotated driving means, the clutching is effected by a lever with unequal arms, the longer arm being engaged by the wiper-carrying member during the throw-over of the clutch and the shorter arm engaging the movable part of the clutch. In the construction shown, a spindle 2 with a steeply-pitched thread is mounted in a casing 1 and at one end extends through a bearing 4 to carry two bevel pinions 7, 8, which engage a third bevel pinion 10. The pinion 10 is adapted to be driven from a source of power. A clutch member 13 splined to the spindle between pinions 7 and 8 is provided with pegs 14, 15. The peg 14 is adapted to engage a pin 17 on the pinion 7, and the peg 15 to engage a pin 16 on the pinion 8. The clutch member is grooved for engagement by a lever 18 secured to a spindle 26 which also carries a lever 25. The lever 25 at its outer end is engaged by a fork 24 formed on the end of a slidably-mounted reversing bar 19. This bar is provided with blocks 20, 21, each of which is fitted with a spring. The wiper-carrier 6 engages the screwed spindle 2 and projects through a longitudinal slot formed in the casing 1. As the spindle rotates, the wiper is moved along the screen, the carrier 6 eventually engaging one of the blocks on the bar 19, for example, block 21, through the spring 23. The bar 19 is thus operated to swing over the levers 25, 18 so that the peg 14 is disengaged from the pin 17. The clutch member 13 being thereby released is moved by the expansion of spring 23 so that the pin 16 is brought into engagement with the peg 15 causing reversal of the rotary movement of the spindle 2. This reverse movement continues until the carrier 6 engages the block 20 through the spring 22. More than one wiper may be used and each wiper may be driven by a separate carrier such as 6.

Abstract: 907,301. Photographic cameras with exposure meters. AGFA A.G. Nov. 14, 1958 [Nov. 23, 1957], No. 36757/58. Class 98 (1). A photographic camera having a built-in exposure meter with a follow-up pointer comprises a transmission mechanism connecting the follow-up pointer with the camera exposure setting means and film-sensitivity setting means, said mechanism comprising two members arranged for relative movement while in mutual engagement so that the two setting means are not operatively connected to each other. Two examples are given, illustrated by Figs. 3 and 4 respectively, in which the shutter 4 on objective mount 2 has coupled adjustment means for the aperture and the shutter speed. To adjust the shutter the rod 6 is moved longitudinally by means not shown in Fig. 3 and this movement is then transmitted through the segment 14 to a lever 17 the free end 17a of which moves a rack 18 and hence a pinion 19, a cam 20 and the follow-up pointer 21. This pointer can also be moved by rotating the film sensitivity device 8 which in turn rotates the shaft 6 and the segment 14. Considering Fig. 4, the control member 6 comprising two threaded members 6a, 6b is moved longitudinally when shutter 4 is adjusted and 6b moves rotatably and longitudinally, when the film sensitivity device knob 36 and cam pinion 34 is rotated. The lever 27 is then rotated against a spring 27 and the following pointer moves. The objective mount 2 is screwed on to the surface of the camera housing so that small adjustment displacements of the objective are possible.

Abstract: 1418994 Electrode boilers R H EATONWILLIAMS 4 Feb 1974 [16 Feb 1973 3 Aug 1973] 7835/73 and 36934/73 Heading F4A [Also in Division G3] The water level in an electrode boiler 11 is sensed by an electrode 27 connected to a circuit 29 which operates a solenoid controlled valve 20 in a town water supply line connected to the bottom of the boiler through a strainer 18 and flow regulator 19. The circuit 29 may include a hysteresis device to prevent rapid switching of the valve 20. The boiler 11 has a steam outlet 16 connected to a humidifier in an air-conditioning plant, and main electrodes 14, 15 which may be rolls of wire mesh connected to supply terminals 31, 33. The electrode current is sensed by a transformer or series resistor 32. As the boiler produces steam, and fresh water is supplied, the concentration of dissolved minerals and particles in the water increases, so that the conductivity rises, and eventually the electrode current reaches a level at which the sensor 32 causes a solenoid 25 to open a drain valve 24. This valve remains open until the current has fallen to a predetermined lower value, whereupon feed valve 20 is opened and the water is restored to its normal working level. An electronic control circuit, including bidirectional controlled rectifiers and integrated circuits, is also described, Fig. 3 (not shown).
