Title: Electroplating machine
IPC: C25D17/28
Filed: 1974-01-14
Abstract: 1400698 Apparatus for electro-plating articles CHEUNG WAI-MANUFACTORY Ltd 14 Jan 1974 01585/74 Heading C7B In an electro-plating apparatus in which the workpiece is supported by a pivoted arm 22 mounted on a carrier 12 which is movable along a predetermined pathway alongside the plating bath, a cam track 40 is present alongside said path, which, as the carrier travels along said path, causes the arm to move to a lower position thus immersing the workpiece in the plating bath and thereafter causes the arm to return to the higher position thus raising the workpiece out of the bath. The workpiece is attached to a conductive part of the pivoted arm which is insulated from the carrier, and means are provided whereby electric current is supplied to the workpiece via the conductive part whilst the arm is in its lowered position. The conductive part may include a brass ring which, whilst the arm is in the lowered position, runs along a bus-bar Fig. 3 (not shown), or the arm may contact a movable terminal supported on a track, the arm moving the terminal along the track whilst in the lowered position, and releasing the terminal when raised to the higher position, the terminal then returning automatically to its original position Fig. 4 (not shown).

Abstract: 343,273. Gramophone pick-ups. HOUGH, T., 62, Glengall Road, Peckham, London. Jan. 16, 1930, No. 1607. [Class 40 (iv).] In a sound reproducing or recording apparatus, such as a gramophone pick-up, of the kind comprising a permanent magnet 1 and associated polepieces 2, between which an armature 13 carrying a stylus or cutter holder is arranged to vibrate so as to produce corresponding current variations in coils 21, the support for the armature is constituted by elements 20 of rubber or like resilient material inserted between the armature and pole-pieces, the arrangement providing a universal mounting that permits the device to be used with, or for the production of, either hill-and-dale or lateral-cut records. Each polepiece 2 in the construction shown is of bifurcated form with the coils 21 disposed in the recessed portions. The lower flange 6 of the polepiece is furnished at its forward edge with a groove 10, Fig. 3, while a block 14 on the armature 13, Fig. 5, has a corresponding groove 16, the elements 20, preferably in the form of rubber cord or rubber tubing with a hard core, being accommodated in the grooves. Notches 11, 17 along the edges of the grooves 10, 16 respectively prevent accidental displacement of the rubber elements. At its upper end the armature 13 terminates in an obliquely set blade 12 which moves in the gap between inclined surfaces 9<1>, Fig. 6, on the upper flanges 5 of the polepieces so that, whether the blade 12 vibrates in the direction "a" for lateral-cut records or in the direction " b for hill-and-dale records, it has imparted to it the necessary relative movement towards and away from the surfaces 9<1>. Adjustable damping pads of rubber or like material are mounted on the upper flanges 5 of the polepieces 2 and adapted to bear against the blade 12. When used as a reproducer, the output may be varied by arranging the magnet and polepieces to be relatively adjustable.

The pockels-effect body preferably comprises a Z-cut crystal of potassium tantalum niobate, ADP or KDP, and the fluid an aqueous solution of potassium iodide or a glycerol solution of stannous chloride dihydrate. If the pockels-effect body is soluble in water two cover slips of fused quartz are bonded on faces 29 and 30. Loops 19 and 20 may be nickel square loops, the crystal 11 having the shape of a cube and being located within housing 12 of square internal and external cross-section, and silicone rubber O-rings 17 and 18, and seals 23 and 24 being positioned as shown. The fluid chambers are closed by prisms 15 and 16 of fused silica or sapphire, the outer faces 25 and 26 of which being inclined to their inner faces 27 and 28, which are parallel to the faces 29 and 30 of crystal 11, at the complement of the Brewster angle # of the material of the prism relative to air for light of a given frequency. Thus if the incident light beam 31 is plane polarized parallel to the plane of incidence and is incident upon face 25 at the Brewster angle there is no loss of light due to reflection at face 25. The embodiment shown is suitable for use with a quarterwave voltage, but if a half-wave voltage is applied prism 16 is arranged relative to prism 15 so that the plane of incidence of ray 32 at face 26 is parallel to the plane of polarization of the ray 32 on emerging from the crystal 11 when the half-wave voltage is applied, so that no reflection occurs at face 26.

Abstract: 1,216,972. Transformers. IRD MECHANALYSIS Inc. 13 Jan., 1969 [11 Jan., 1968], No. 1856/69. Heading H1T. A proximity transducer is made by winding a coil 23 of wire in a groove between forward, 11, and rearward, 13, portions of a non-metallic bobbin portion 11, 12, 13 (Fig. 1, not shown); inserting and securing the bobbin portion entirely within a metallic cylindrical sleeve 16, as shown; and cutting off the forward end of the sleeve 16 and the forward end of the forward portion 11 of the bobbin along the line 25-25, so that the coil 23 is rigidly secured in the sleeve 16 adjacent to its cut-off end (27) (Fig. 3, not shown). The forward end of the sleeve and bobbin may then be machined to achieve the required response characteristic for the probe. The bobbin may be secured by an encapsulating material such as epoxy resin with which the sleeve 16 is filled. Grooves 17, 18 enable connections to be made and a central well 28 may be provided for a temperature-sensing device. An enlarged cylindrical portion 15 is originally attached to the bobbin portion to limit the entry of the bobbin portion into the sleeve.

[Also in Division G4/6] Filters 3, through which the coolant gas of a nuclear reactor is passed via valves 4, 5, are periodically cleaned by closing valves 4, 5, releasing the pressure in chamber 2 by opening valve 7, evacuating a shielded chamber 13 and chamber 2 through line 15, with valve 11 open, and finally closing valve: 16 and opening valve 8 to allow a blast of atmospheric air through filters 3, blowing the radioactive dust therefrom into chamber 13. Valve 16 may then be opened again and more air allowed to flow from valve 53 down tube 52 (Fig. 4, not shown) to carry any dust remaining in the bottom of chamber 2 into chamber 13. The chamber 2 may also be evacuated directly through line 75 and valve 8 opened to blow the dust to the bottom of the chamber. Chamber 13 has a double wall and a cooling system comprising fan 56 which draws air therethrough. The vacuum line 15 is connected to chamber 13 through a filter assembly 17 (Fig. 5, not shown), which includes a non-return valve (74) and a manually operated shut-off valve (68), whereby the inlet pipe (59) and the filter chamber (62) may be closed off before the assembly is removed from floor 57 for changing the filter element (63). In Figs. 1, 2 (not shown) the circuit is simplified, but a more complex filter assembly 17 is used, in which filter elements (28) may be dropped into chamber 13 after use and replaced by new elements, lowered down a tube (24) and moved into the operative position by a rotatable quadrant (26). The element (28) is finally engaged by the screwed end (37) of a 'bolt (34), lifted up tube (22) to allow quadrant (26) to be rotated back, and then lowered into space (45).

IPC: F04D17/18
Filed: 1927-01-26
Abstract: 265,199. Mercier, R. Jan. 26, 1926, [Convention date]. Centrifugal Sprengel pumps and condensers.- Vapours are condensed and non-condensable gases are extracted by means of a number of rotors on the same shaft; some of the rotors pass streams for the condensing vapours while the others pass carrying fluid at a velocity great enough to ensure the extraction of the gases. The number of rotors can be varied according to requirements and in the form shown in Fig. 1, three are employed. The centres of these rotors 4, 5, 6 are connected by the conduits 7, 8 to a reservoir of fluid such as cold water. The rotors are vaned and the outside pair 4, 5 project streams across the space 12 to the diffusers 9, 10. The space 12 crosses the chamber 16 which is supplied with vapour by the conduit 17; the vapour is condensed and carried by the liquid streams through the diffusers 9, 10 into the volute 14. The central rotor 6 has a larger diameter than the other two or has smaller nozzles so that its liquid stream crosses the space 12 with a greater velocity than the other streams. On account of its velocity the stream entrains the non-condensable gases and carries them through the vaned diffuser 11 into the volute 14.
