Title: Rotary positive-displacement fluid pump or fluid operated motor
Inventor: CHARLSON L
IPC: F04C2/10
Filed: 1969-03-31
Abstract: 1,235,394. Rotary positive - displacement pumps and motors. GERMANE CORP. March 31, 1969 [Dec.31, 1968], No. 16837/69. Heading F1F. A reversible pump, or motor, has a star member 25 rotatable in a planetary manner while meshing with a fixed ring-member 24 and coupled to a power-input, or output, shaft 38 by a splined member 66, which can abut a ring 69, flow of working fluid e.g. oil, between inlet and outlet ports 18, 19 and cells 29 being controlled by a rotary valve-member 31 connected to the shaft by a shear pin 51 and furnished with openings 60, 61 for pressure balancing. The valve-member is supported by the wall of a bore 15 and separated from the shaft by an annular gap of width X, the shaft being supported by bearings 39, 40 situated between thrust bearings 46, 63. Annular grooves 33, 34 in the valve-member are in register with the ports 18, 19 and intersect alternate slots 35, 36, respectively, which slots during rotation of the valve-member periodically and sequentially communicate with the cells through corresponding openings 21 and passages 20. The openings 60, 61 communicate with respective annular spaces between sealing rings 57, 58, 59 lodged in the valve-member. A conduit 70 and passages 71, 72 facilitate lubrication of the bearing 46 by the working fluid leaking from the high-pressure regions. The rings 57, 58, 59 may be replaced by three rings (75), Fig.5 (not shown), lodged in the shaft. Alternatively, the openings in the valve-member communicate with annular spaces between sealing rings 86, 88 and 88, 89 or 89, 91 and 91, 86, respectively, depending upon which of the ports 18, 19 contains the fluid at the greatest pressure, the sealing rings being of the non-return type. As another alternative, openings 106, 110 in the valve-member communicate with annular spaces between sealing rings 101, 102, 109, the rings 101, 102 being axially movable within slots 97, 99 in accordance with the pressures at the ports 18, 19. An opening 104, or 107, effects axial displacement of the respective ring towards the ring 109 due to working fluid leaking from the highpressure regions through this opening towards the port 18, or 19, containing the fluid at the lowest pressure. This arrangement, and that comprising the rings 86, 88, 89, 91, augment the area internally of the valve-member upon which the high-pressure working fluid can act. (For Figures see next page)

Title: Improvements relating to the Recovery and Utilisation of the Cyanides Contained in the By-products Obtained in Gas Works.
Inventor: BAKER HARRY
IPC: C01C3/08
Filed: 1917-11-16
Abstract: 120,759. Baker, H. Nov. 16, 1917. Cyanides; sulphocyanides; ammonia. - The residual liquor left after the distillation of gas liquor with lime or the like is boiled down with sodium or potassium carbonate to decompose certain cyanogen compounds with the production of ammonia. A compound of a metal other than mercury is then added to precipitate the remaining cyanides and sulphocyanides, or the liquor may first be used as often as desired instead of lime for the distillation of gas liquor, alkali carbonate being added as described above, at each operation, the residual liquor being finally precipitated as described above. The precipitated cyanides and sulphocyanides may be separated from the alkaline liquor, which may then be used instead of lime for the distillation of gas liquor or for dissolving the metal compound used for the precipitation of the cyanides in a subsequent operation; or the liquor, containing the precipitate, and it may be also calcium carbonate derived from the lime originally used in the distillation, may be evaporated to dryness. Spent oxide from gas purifiers is washed or boiled with solution of alkali carbonate, and the solution obtained is concentrated to decompose certain cyanogen compounds and then precipitated as above described. The precipitated cyanides and sulphocyanides or the mixture obtained in the evaporation to dryness above described, or the cyanogen compounds obtained according to Specifications 110,819 and 112,329 are heated with or without the addition of alkali carbonate and in the presence or absence of air to obtain ammonia. In the presence of air, an oxide is obtained which may be used again, and as the ammonia is first liberated and subsequently sulphur dioxide, it is possible to collect them separately. In the absence of air, a sulphide is obtained which may be roasted to obtain an oxide or may be treated with an acid to obtain a solution which, after neutralization, may be used for the precipitation of the cyanides as above described.

Abstract: 860,795. Wafer sandwich making machines. BAKER PERKINS Ltd. May 20, 1959 [May 27, 1958], No. 16912/58. Addition to 785,435. Class 28 (1). A wafer or like sandwich-making machine comprises a continuously-travelling conveyer mechanism with an upper infeed section whose delivery end is periodically retracted to deposit creamed wafer sheets, arrested in succession by the upper part of a stop mechanism, on a lower conveyer section, which it overlaps, and where the wafers are held by the lower portion of the stop-mechanism until a completed sandwich is formed in which a dry wafer sheet is incorporated as the top layer, the lower stop-portion being then withdrawn to allow the sandwich to proceed on the lower conveyer section. Wafer sheets are marshalled as described in Specification 785,434 and the dry wafer sheets are fed in succession by a conveyer 10 to trays 11 supporting the ends of a sheet 12, which is arrested there by fingers 13. Creamed wafer sheets 14 are fed in succession, spaced uniformly, creamed surface uppermost, to the stop-fingers 13 by a conveyer belt 15 passing round a roller 17 mounted on a carriage 18 which is then retracted by a cam 19 to remove the support of the belt 15. The wafer sheet drops on to a conveyer 20 and is arrested by a stop 21 vertically aligned with stop-fingers 13. Conveyer 20 is formed by three V-belts between which stop 21 fits upwardly. Carriage 18 is retracted twice more and just before the second time a dry wafer is deposited on the creamed wafer engaging fingers 13. After the wafer sandwich is completed, stop 21 is lowered and conveyer 20 carries the sandwich under a presser unit. Conveyer 10 is driven by a chain 100 from a drive-shaft 101 driven from the marshalling unit and carrying a gear 102 meshing with a gear 123 on a main cam-shaft 23 carrying cam 19. Conveyers 15, 20 are driven through chains and gearing from shaft 23 through gearing drives shaft 32 at onethird of its own speed. Trays 11 and stop 21 are actuated respectively by cams 30, 31 on subsidiary cam-shaft 32. If four creamed wafer sheets are to be incorporated in a sandwich, shaft 32 revolves at one-quarter of the speed of shaft 23. Conveyers 15 and 20 may be replaced by a single conveyer, Fig. 4 (not shown).

Title: Improvements in or relating to methods of simultaneously transmitting a large numberof independent electric currents through a single channel
IPC: H04N7/08
Filed: 1932-06-16
Abstract: 402,855. Multiplex signalling. CRAIG, T. J. D., 6, Ickworth Road, Sleaford, Lincolnshire. June 16, 1932, No. 17041. [Classes 40 (iii) and 40 (v).] In a multiplex carrier system, particularly for use in a television system in which each carrier denotes the intensity of illumination in one element of a picture, the carriers are produced by modulation at the transmitter ; each of a set of acoustic frequencies is modulated by a set of low frequencies which have themselves been modulated in accordance with a set of picture elements. The resulting currents are then applied to a line or a wireless transmitter. The group of oscillators 01, 02, 03, of which only three are shown, produce low frequencies 50, 55 ... up to 100, and the same set of frequencies is produced by each of the other groups 04, 05, .. and 07, 08 .... The oscillators 01 02, 03 feed a modulator MA through light-sensitive cells C1, C2, C3, which correspond to certain elements of the transmitted picture, and the resulting picture currents are fed to a modulator MA together with current of frequency 500 from an oscillator OA. The output comprises frequencies 500, 550, 555..., modulation products outside the band 500- 600 being eliminated by the filter FA. In order that duplicate modulation frequencies may be avoided, none of the oscillators 0 has a frequency lower than 50. The oscillators OB, Oc ... produce other frequency bands, which are separated at the receiver by filters GA, GB, Gc, and passed through modulators NA, NB, Nc which reproduce as difference tones the original frequencies of 50 .. 100. These are applied to electrical or mechanical resonators V, which control the elements of a screen on which the picture is reproduced. The receivers may comprise vibrating reeds which hide or are hidden by fixed surfaces except when they are vibrating.
