Title: An industrial capillary viscometer
Inventor: MULLER RUDOLF
IPC: G01N11/06
Filed: 1963-05-27
Abstract: 1,021,049. Measuring viscosity. FARBENFABRIKEN BAYER A.G. May 27, 1963 [May 26, 1962; Aug. 30, 1962], No. 21109/63. Heading G1S. An industrial capillary viscometer for fully automatic measurement of the viscosity of conductive liquids comprises a measuring vessel 4 with a capillary 5 and three electrodes 10, 11, 12. The vessel 4 is immersed in a vessel 2 through which an emulsion to be tested is flowing and suction is applied through a tube 13 until the emulsion rises to the level of the electrode 12. This operates an electrical delay switch which stops the suction and applies pressure to a piston 26, thus raising the measuring vessel above the level of the emulsion. The emulsion flows from the measuring vessel through capillary 5 and when the emulsion drops below the level of the electrode 12 a switch is operated to start a timing operation. When the level drops below the electrode 11 the timing operation is terminated and the measuring vessel is automatically lowered into the emulsion. The time may be measured by a synchronous motor with a transmitter potentiometer connected in series, Fig. 2 not shown, and the measured valve may be switched at the end of this measurement to a recorder. Alternatively the synchronous motor may operate the rolls of a rotary mechanical counter. Alternatively Fig. 3 not shown, the time may be counted stored and indicated by a frequency reducer, a three-decade impulse counter, a three-decade storage mechanism and associated gate circuit groups, amplifier and visual decades. The measuring vessel 4 may be lowered into a container 22 containing water for washing and comparison.

Title: Improved freely rotating wheel for toy vehicle and method for assembling same
IPC: A63H17/26
Filed: 1971-04-19
Abstract: 1299052 Toy wheels MATTEL Inc 19 April 1971 [27 Nov 1970] 21218/71 Heading A6S A wheel 48, includes a central opening 54 having a cylindrical wall 56, which acts as a bearing surface against an axle 38. Aligned with the opening 54, having a coincident longitudinal central axes is a second opening 58. An annular recess 62 is formed in the wall 60 of the second opening to accommodate a spherical thrust bearing 74 which may be a steel ball. To prevent lateral movement of the wheel one end 70 of the axle is swaged to have a diameter larger than the opening 54, and thus abuts the conical section 66 connecting the openings. The steel ball 74 is held in place by annular lips 73, and therefore movement of the wheel 48 in the other lateral direction is prevented by abutment of the steel ball 74 and the flat surface 72. The wheel 48 may be integrally moulded of resilient material.

Title: Improvements in or relating to electrical phase-sensitive devices and the like
Inventor: CRAVEN ROYSTON ARTHUR FREDERIC
IPC: H01J17/36
Filed: 1952-08-25
Abstract: 721,398. Valve relay circuits. WATFORD ELECTRIC & MANUFACTURING CO., Ltd. Aug. 17, 1953 [Aug. 25, 1952], No. 21335/52. Class 40 (6). In a phase sensitive device in which one or other of two gas-filled valves V1, V2 is fired when the input to the grids leads or lags the anode supply, a third valve V3 is arranged with its anode supply in quadrature so that, when short pulses of current occur in the associated valve V2, long pulses occur in the valve V3. The invention is stated to prevent chatter in relays and is used for the connection and disconnection of power factor correcting capacitors. The valves V2, V1 are energized in antiphase, Fig. 3, and are normally maintained non-conducting by bias derived from potentiometers P1, P2. A current transformer CT feeds pulses 33, 34 over a peaking transformer T2 which occur when there is no positive potential on the anodes when the system is operating at unity power factor. If the current lags the voltage, the pulse 33 fires valve V1 which remains conducting for most of the remaining half-cycle, providing adequate current to operate relay K1. When the current leads, the pulse 34 fires valve V2 near the end of the half cycle causing a short pulse of current to flow in valve V2. A voltage pulse is applied to valve V3 which is energized from phase C and neutral N and is thus in quadrature with the voltage from phases A and B. Current flows for at.least a quarter-cycle, increasing as the current leads further. Relays K1, K2 operate a reversible motor operating cams to connect and disconnect power factor correcting capacitors.

Filed: 1931-07-27
Abstract: 381,636. Treating photographic prints &c. PAKO CORPORATION, 1006, Lyndale North, Minneapolis, Minnesota, U.S.A.-(Assignees of Houch, J. W. and Dye, G. M. ; 1006, Lyndale North, Minneapolis, Minnesota, U.S.A.) July 27, 1931, No. 21441. Convention date, March 9. [Class 98 (ii).] A machine for handling articles, e.g. photographic prints, through treating liquids comprises a series of vessels each provided with a pervious receptacle which is movable to discharge its contents into the next adjacent vessel of the series. As shown, a long tank 17 supports a series of vessels 25 each fitted with a basket-like receptacle 33 formed of open metalwork plated with rubber. Each receptacle is supported by arms 34 from a shaft 35 furnished at each end with arms adapted to be engaged by dogs on side chains to move the receptacle out of the vessel and back again. The tank 17 is pivotally supported by belts 16 in a fixed frame and is rocked to agitate the liquids in the vessels 25 by a shaft 77 furnished with a crank engaging a fixed guide block. Water is supplied to the last vessels of the series by pipes 29, 30 and overflows through openings 25a into the tank 17 which is fitted with a drain connection 31, 32. The first vessel contains a stop solution and the following vessels a fixing solution. A motor 84 drives the shaft 77 through a belt 82, pulley 81, and worm gear. A cam on the shaft 77 operates through a block 93 and bar 94 a ratchet 97 having an internal cam controlling a clutch member 68 adapted to be driven from a clutch member 69 on the shaft 77 and to operate the side chains through bevel gears 65, 66 and cross shafts. In operation, the tank is first rocked to agitate the liquid in the receptacles ; after a predetermined interval, the cam ratchet 97 allows the clutch 68, 69 to close and, through the side chains, the receptacles 33 are successively turned to discharge their contents and returned to receive the contents of the next preceding receptacle. The last receptacle discharges its contents on to a roller conveyer 39. During the movement of the chains the pawl bar 94 is rendered inoperative by an external cam on the ratchet 97, but after the discharge cycle is complete a cam dog on one chain actuates a second pawl to turn the ratchet 97, opening the clutch 68, 69 and freeing the bar 94 for a fresh cycle. The last vessel 25 may contain a glazing solution : in this case the chains are arrested in such a position that the receptacle is raised from the vessel as shown in dotted lines. The machine may be contiguous to the dark room, the first vessel being protected by a light-excluding hood 106 fitted with a depending partition 112. During the discharge from the first vessel, the hood is moved back, on rollers 118, by links 113.

Title: Improvements in means for facilitating the inspection of tubular fabrics
IPC: D04B35/00
Filed: 1922-08-08
Abstract: 185,400. Kolb, J. F. Aug. 31, 1921, [Convention date]. Inspecting.-In a device for inspecting tubular fabrics, a lamp disposed within the tube of fabric has electrical connection with a source of current by means extending through the fabric. As shown, a knitted tubular fabric a, drawn by a tension device c from a knitting-machine b, is spread by a frame d carrying an arm f and lamp g, and the pins or teeth r of a conducting-wheel q, rotated by the movement of the fabric, pass through the wall of the fabric and between a pair of spring contacts l connected to the lamp. The contacts l are carried by conducting-plates x disposed on the outer sides of guide-plates i which are bolted to the two sides of a spacing non-conducting block h, the contacts being arranged to pass through arcuate slots k in the guide-plates. The arm f is connected by a wire i to one of the lamp terminals and the plates x are connected by a wire m to the other lamp terminal. Current from the source passes through the machine frame to the spreading- frame and so by the wire i to the lamp. From the lamp the current passes by the wire m to the contacts l and then by the wheel q, conducting- block s, and wires u, v back to the source. In cases where it is undesirable to pass the current through the machine another wheel q is mounted on the opposite sides of the block p and an additional set of guide-plates and contacts l is provided; one wheel then serves to introduce the current and the other to lead it off.
