Abstract: 599,140. Electrolytic reduction; liquid-electrode apparatus. HOFFMANLA ROCHE, Inc. Feb. 14, 1945, Nos. 3708 and 3709. Convention dates, Feb. 17, 1944. [Class 41] In a cell for reduction, e.g. of a sugar acid lactone, comprising a mercury amalgam cathode 4 and anode 9 enclosed within a porous chamber 8 the catholyte liquid is impelled into the cathode chamber in contact with the cathode surface by an injector 13 in sufficient force to maintain agitation of the catholyte without appreciable agitation of the liquid cathode. The catholyte overflows by pipes 12 of adjustable height the lower ends of which dip in a reservoir 2 cooled by brine coil 17. The injector 13 may comprise a circular tube having orifices immediately above and directed tangentially to the cathode surface. The liquid cathode rests on a dished member 3 provided with wells 5 into which graphite supply poles project. The anode chamber 8, which may be of unglazed porcelain or alundum, rests on lugs 7 on the member 3 ; it is provided with a cover 10 of glass, plastic, hard rubber or glazed ceramic having a port 11 for withdrawal of oxygen or ozone. The anode 9 may be of platinum mesh or of lead or lead peroxide. The cathode chamber is provided with a cover 18 carrying.ports 11a for withdrawal of hydrogen also a dropping funnel 23 supplying dilute sulphuric acid for adjustment of pH, and holes for the introduction of thermometers and control equipment. Catholyte is returned by a pump from the reservoir to the injector 13 through a temperature regulator. The circulating system is byepassed through apparatus containing pH electrodes connected to an indicating and recording system. The reservoir may be charged at commencement by suction from an electrolyte container. Alternatively the catholyte may be circulated through the cathode chambers of a number of cells in cascade. The anolyte may consist of 3N sulphuric acid and the initial catholyte contains 75 gms. per lit. of sodium sulphate at pH 8.5. After running for 1¢ hours circulation is stopped and part of the catholyte withdrawn into a container where the material to be reduced, e.g. d-glucose or a sugar acid lactone is introduced and dissolved, the withdrawn catholyte then being returned to the circulating system.

When a coin is inserted in a slot 6 and the drum partially rotated by the handle 32, the coin is forced by the wall 11<a> of the drum against a ramp 24 on a member 21, pivotally mounted on the drum shaft 3, and displaces a detent 18 from between projections 14, Fig. 7, on the rear of the drum. The drum can then be rotated to permit an article to fall from a compartment through a delivery opening in the cover 11, the succeeding slot 6 being correctly positioned behind the slot in the cover by a spring-controlled finger 29. Alternatively, the slots 6 may be positioned by a spring on a stationary part of the apparatus engaging a pin on each of the partitions. In another arrangement only one pin is provided and this on the partition 9, the spring abutting against this when the first article is being sold and subsequently abutting against the coins in the slots 6. Fig. 12<a> shows the arrangement of the slot in the cover 11 when the apparatus is mounted in an inclined position. Testing coins.-The side 52, Fig. 14, of the slots 6 is inclined and provided with a projection 53 for engaging perforated coins, washers or the like to prevent actuation of the ramp thereby. A pointed member 55, Fig. 17, mounted on a spring 56 on the rear of the drum and pressed by the ramp through an aperture 58 in a member 57 may also be provided to prevent operation of the ramp by coins of soft material.

Title: Improvements in or relating to control valves for fluid-pressure brake-operating mechanisms
Inventor: JEFFERY HAROLD
IPC: B60T15/04
Filed: 1956-02-08
Abstract: 812,424. Fluid-pressure brakes. CLAYTON DEWANDRE CO. Ltd., and BRITISH TRANSPORT COMMISSION. Feb. 1, 1957 [Feb. 8, 1956], No. 3961/56. Class 103(1). [Also in Group XXIX] In a control valve for fluid pressure brakeoperating mechanism in which a pedal or like actuator acts on the fluid control means of the valve through a main spring and in which a reaction force proportional to the braking pressure acts through the spring against manual effort applied to the pedal, a spring-loaded abutment is provided to limit the movement of the actuator and hence determine the maximum braking pressure for normal operation. This abutment yields under increased manual effort to enable the fluid control means to be actuated by rigid transmission of manual effort from the actuator in the event of failure or breakage of the main spring without recourse to the main spring. This abutment comprises a ring 17 pressed by a spring 18 against a shoulder in an upper casing part 2. The ring is arranged to limit the downward movement of a disc 12. This disc is held against a shoulder 21 on an input rod 9 by the main spring 11. The rod 9 is rigidly connected with the pedal. The spring 11 acts through the base of a guide member 14 on the head of a thrust rod 3, the latter being guided in the rod 9 and acting through a beam 5 on the fluid control elements 6, 7. If only one such element is provided, the rod 3 acts directly thereon. The spring 18 also abuts a fixed ring 15 supported on a shoulder formed by the lower casing part 1. After the ring 17 yields, the disc 12 acts directly on thrust rod 3 through a sleeve 20.

Filed: 1962-02-05
Abstract: 963,299. Weighing apparatus. J. H. COMBRIDGE. Jan. 21, 1963 [Feb. 5, 1962], No. 4302/62. Heading G1W. [Also in Division G3] An apparatus which may be used to divide a flow of material into portions by weight comprises a double wheel provided with a plurality of containers to receive the material which may be liquid or granular. Each container 3 is counterbalanced by a weight 5 on a lever pivotally mounted on the wheel. In operation the wheel is held stationary by stop levers 2 and 14 and as material is poured into a container it swings downwards on its support lever until a projection of the lever engages a balance lever 7. When a predetermined maximum weight is in the container the opposition of a counterweight 8 on the lever 7 is overcome so that lever 7 rotates about its pivot and disengages from the container support lever. The latter lever continues to rotate and engages and moves a trip lever 9 which by means of a chain 10 pivots a lever 10 and the stop lever 2. The lever 2 is thus disengaged from a wheel spoke 1 allowing the wheel to rotate by the action of the weight of material in the container 3 and in the lower containers. Lever 9 disengages from the container support lever and together with lever 11 is returned to its initial position by a counterweight 12. The wheel thus rotates a step, the next empty container receives material and the cycle is repeated. The speed of rotation of the wheel is therefore proportional to rate of filling a container and the application of the invention to the measurement of time is suggested.
