Abstract: 1,265,976. Cleaning rails; increasing adhesion. BRITISH RAILWAYS BOARD. 10 Dec., 1969 [30 Dec., 1968], No. 61695/68. Heading B7J. [Also in Divisions H3-H5] A plasma torch, for cleaning rails and improving wheel-rail adhesive, has the current density at the arc root reduced by maintaining the overall temperature of the anode block at an elevated value of at least 250 C. An insulated resistive heating element 1 is provided in a water-cooled anode block 3, Fig. 1, to achieve an overall anode temperature of about 500 C. Alternatively, a high-boiling point liquid such as a silicone liquid is circulated as coolant through the anode block 3 and through a heat-exchanger 9, Fig. 2 (not shown), by a pump 10. A further arrangement uses a refractory anode block 3 of tungsten, carbon, boron nitride or silicon nitride which is gas-cooled, e.g. by argon, fed via an inlet 11, Fig. 3, to annular chamber 12 and thence via passage 13 into the anode opening 4, providing " film " cooling.

Abstract: 1288488 Laminated anodes and cathodes UNION CARBIDE CORP 20 Feb 1970 [20 Feb 1969] 8302/70 Heading B5N [Also in Division H1] A flat primary galvanic cell is made by combining a cathode laminate and an anode laminate produced in separate operations. As shown the cathode laminate is made by covering one surface of an electrically conductive thermoplastic film 10, such as a vinyl film loaded with carbon, with a cathode mix 12, e.g. finely divided MnO 2  and carbon, and then applying separator 14. The laminate is then placed on a web of electrically non-conductive heat-sealable thermoplastic film 16 having a margin 18 extending outwardly and a central aperture for making electric contact to the electrically conductive film. The anode laminate is prepared from a metal sheet 20, e.g. zinc, on to one surface of which is secured a web of electrically non-conductive thermoplastic film 24 which also has a marginal portion 26 extending outwardly and a central aperture 28 for making contact to the metal. A layer of immobilized electrolyte is provided and in the embodiment shown comprises a layer 22 of an aqueous paste of NH 4 Cl containing ZnCl 2 , which is applied to metal sheet 20 and is backed by separator 14a, e.g. of micro-porous paper. The two laminates are then juxtaposed and the marginal web portions are sealed together forming seal 30. A metallic foil 32, e.g. tin-coated steel, is applied to the outside of cathode web 16 and deformed through central aperture 34 of web 16 to make electrical contact with cathode collector film 10.

Abstract: 1296231 Automatic exchange equipment STANDARD TELEPHONES & CABLES Ltd 10 Sept 1970 [18 Sept 1969] 46046/69 Heading H4K In a telephone exchange having control units which are taken into use for a plurality of short periods during the establishment of a call and registers which are seized for the whole period of establishment of a call, the registers and control units are grouped and each group of registers is allocated to a group of control units so that each register in the group has access to each control unit within the allocated group but no access to any other control unit. A typical exchange using a control unit is shown in Specification 1,057,218 and the invention is more particularly applied to the sectionalized exchange shown in Specification 1,165,526. As shown a typical group comprises four control units of which one, MCV1, is shown and a plurality of register circuits mounted in identical racks 1-4. Associated with each register circuit is an electronic switch SW through which each register circuit can be connected selectively to any of the control units of the group. Each control unit is provided with a store which contains information about which registers of its associated group are engaged in establishing a call and ensures that such registers are repeatedly checked to see if they require further assistance. The signalling between the control units and registers may occur in a time divided manner.

In the examples dopants are arsenic pentoxide antimony trichloride, phosphorus pentoxide, boric acid and gold chloride and the surfaces are heated in a subsequent step to 1000- 1200 C. to permit diffusion of the dopant atoms. Surfaces treated include silicon and gallium arsenide.

Title: Mechanical apparatus for cheque writing
IPC: B41K3/00
Filed: 1970-04-08
Abstract: 1307077 Printing cheques and indicating low bank balance ADDMASTER CORP 8 April 1970 16756/70 Headings G4B and G4T A calculator includes means for setting up amounts and printing the same on cheques, means for subtracting such amounts from an accumulator adapted to store an amount corresponding to the bank balance of the calculator's user, and means controlled by the accumulator for preventing operation of the setting means when the amount stored in the accumulator falls below zero. The user is thus reminded to deposit a further amount and this amount can then be entered into the accumulator to reenable the setting means. Setting up and subtracting.-As shown, the setting means comprises sectors 11, Fig. 1, which can be differentially rocked anticlockwise from the home position shown to set printing wheels 14. A cycle of motor-driven main shaft 21 then acts through linkage 22-27 and platen 18 to print the amount on a cheque in slot 31. Rotation of shaft 21 also acts through cam 95, Fig. 9, to raise a pin 96 which shifts a frame 56, Fig. 2, carrying the accumulator 51, Fig. 1, to engage the latter with pinion 61. On further rotation of shaft 21, teeth 97, Fig. 9, engage teeth 98 on a member 8 to rotate the latter clockwise to return the set sectors 11 to home position through the agency of universal bar 7. During such resetting, racks 63 on sectors 11 act through pinions 62, 61 to subtract the amount set from the accumulator. Disabling when overdrawn.-The highest order wheel of the accumulator carries a cam 100, Fig. 4, which presents a low region 110 to a lever 101 when the amount stored in the accumulator becomes negative. A rod 103 is thus pulled to the right to rock a lever 104, Fig. 9, clockwise so that a lug 106 coacts with a stop 107 and prevents depression of bar 7 and consequently operation of the sectors 11. Adding.-Movement of a lever 152 to position 152a, Fig. 1, performs three operations to condition the calculator for adding a deposited amount into the accumulator. Firstly, pin 96, Figs. 2 and 9, is moved axially away from cam 95 to prevent engagement of the accumulator with pinions 62, 61 during resetting of the sectors in the next machine cycle. Secondly, rack 113 is depressed and acts through pinions 115, 120, cam 122 and pin 123 to engage the accumulator with pinions 62, 61. Thirdly, rack 114 is moved to the left to rock lever 104 and thus re-enable the sectors 11. The amount to be added is now set up on sectors 11 and is entered directly (not on the return stroke of the sectors) into the accumulator. The main shaft 21 is now driven through one cycle to reset all components for further normal subtraction operation.
