Title: Systems of charging and discharging storage batteries
IPC: H02J7/32
Filed: 1924-03-08
Abstract: 235,282. Della Riccia, A. March 8, 1924. Charging and discharging batteries; boosting; equalizing load on generator.-A storage battery in two halves B1, B3 has its outer terminals connected across the output leads from a generator D, across which at 10, 14 there is also a machine or group with a symmetrically divided flux as claimed in Specification 172,969, the inner terminals of B1, B3 being either cross connected by contacts Y1, Y3 with the intermediate points 13, 11 respectively of the group 10, 14, or direct connected by contacts X1, X3 with the points 11, 13 respectively. The currents in the windings s, t of the group 10, 14 are supplied by shunts from resistances S, T in the output circuit, and are arranged so as to modify the fluxes in the group to give a charging voltage across each half of the battery increasing from a half to full voltage of the generator D and to give a discharging voltage across each half of the battery decreasing from a half of the generator voltage to zero. The contacts X1, X3, Y1, Y3 are operated by shunt current derived from resistances U, V in the output circuit. The various fluxes may be regulated by hand, or when the battery is used as a buffer-battery they may be regulated by a relay and servomotor. Further the solenoids operating the contacts X, &c. may have a single differential winding, and the resistances T, V and S, U may each be combined. The solenoids and their cores may be replaced by small motor devices with differential excitation and angularly movable armatures. Specification 196,893 is also referred to. Reference has been directed by the Comptroller to Specification 172,969 (as open to inspection under Sect. 91 of the Act).

Title: Intermittent marking devices
IPC: B41F17/10
Filed: 1953-03-04
Abstract: 731,106. Selective printing machines. BACHY, A. L. March 4, 1953 [March 4, 1952], No. 6032/53. Classes 100 (2) and 100 (4). A machine for marking strip material e.g. plastic or other flexible tubing 25 comprises a reciprocating hand operated type-wheel unit 38 detachably and adjustably mounted on a plunger 30 sliding in a forwardly and upwardly extending arm 11 of the machine, and a pair of ribbon spools 54, 55, supported for movement with the plunger. The unit 38 contains a series of manually pre-set type-wheels 39 and is slidable in a casing 31 and clamped in position by a front plate 34 held by nuts 35. The casing is attached to the plunger 31 which is formed with a rack 50 for reciprocation from a pinion 49 on a shaft 48 moved by a handle 46, the length of the stroke being adjustable by means of a stop 64-66 on the end of the plunger which engages with the arm 11. The work is fed through a guide 20 comprising an apertured block 21 and a pair of flanges 23. The block and flanges are carried in a slot 17 in a block 14 and clamped in position by screws 19. An adjustable stop 28 in alignment with the guide 20 determines the feed of the material for each operation and the marked material is severed by a knife 26 actuated from a cam 71 as the plunger 30 descends. Inking arrangements.-The ribbon spools 54, 55 are rotatably supported on a yoke 51 secured to the rear of the casing 31; spool 55 has a tension mounting to maintain the ribbon taut and spool 54 has a positive ratchet drive in each stroke motion of the plunger 30. The ribbon 56 is fed through open-ended angular slots 68 in a plate 67 below the type-wheels 39. A pair of clips 69 on the plate 67 adjacent the ends of the type-wheels form pressure bars to engage the tubing 25 to be marked. Alternatively, the ribbon is of the moist kind which inks the type-wheels but is shifted clear, during printing, by cam 85, Fig. 5, which engages endbars 77 slidably mounted on the plate 67 and carrying ribbon guides 83. The ribbon is resiliently urged to ink the ribbon when the machine is in its inoperative position by a backing block 86, Fig. 6, on a spring 87 supported on an arm 88 which moves the block clear during printing.

Title: Improvement in and relating to a lifting truck
IPC: B62B3/06
Filed: 1942-05-06
Abstract: 557,292. Lifting trucks. TRIGGS, W. W. (Yale & Towne Manufacturing Co.). May 6, 1942, No. 6104. [Class 108 (i)] The elevating frame 23 mounted on the main frame 11 by pairs of pivoted links 29 at its ends is lifted by links 39 connected to cranks 20 actuated by the lifting handle 16; each of the links 39 has pivoted to it a rod 45 with a disc 46 acting upon a spring 42 contained in a tube 43 pivoted to the elevating frame 23 so that counterclockwise movement of the link 39 exerts tension on the tube 43 to lift the frame 23 through the medium of the spring 42 in compression, this spring also serving as a resilient support for the frame 23. A dash-pot 64 is connected to the links 39 by pivoted control cams 34 which operate the dash-pot piston 63 through a linkage system 54, 56 and 57. In case of failure of the springs 42 the control cams 34 move to bring faces 50 against a saddle 27 so that the control cams and the elevating grame will be actuated as a unit through the links 39.
Patent GB-700417-A (GB)
Title: Improvements in or relating to methods and apparatus for gluing together a multiplicity of elements
IPC: H05B6/78
Filed: 1951-03-14
Abstract: 700,417. Dielectric heating. GENERAL ELECTRIC CO., Ltd., and SMITH, R. March 14, 1952 [March 14. 1951], No. 6170/51 Class 39 (3) Apparatus for gluing together a number of elements includes a laying-up table 11 from which the elements are transferred by a pusher device 10 to a press 12, and the return movement of the pusher device from the press operates, in succession, means for applying pressure to the elements in the press to maintain the work flat, means for applying transverse pressure which tends to squeeze together the glued surfaces, and finally means for switching on the high frequency supply. The latter is applied to the opposed press platens 30, Fig. 2, the lower one only being shown, which platen is moved upwardly by a number of pneumatically operated double acting rams 31, only one of which is shown, to compress the work and maintain it flat. The pusher device or loader 10 is operated by a double acting ram 20, and a horizontal pressure member 32 is operated by a number of similar rams 33. Air is led from a common supply 22 through a change over valve 23 to the ram 20, and the loader speed is controlled by throttle valves 24, 25. Similarly the rams 31 and 33 are supplied with air through change over valves 34 and 25 respectively. The upper press platen, not shown, is fixed and has along one side a stop of insulating material opposite the pressure member 32. The change over valves are electrically operated, and normally air is admitted to the side of the pistons of rams 31 and 33 such that they retract, and to the ram 20 such that the loader is moved to its outer position. A protuberance 26 on the piston rod 21 operates during the return stroke of the loader from the press, electric switches 41-43 which, in turn, operate a number of relays controlling the energization of the operating windings of the valves 23, 34 and 35. The energisation of these windings causes pressure to be exerted by the rams 31 and 33 in succession and finally, the operation of a switch 44 effects a high frequency supply to the press. A timing device controls the duration of the high frequency supply, after which time all the relays are automatically de-energized. Removal of the vertical pressure is delayed until the horizontal pressure has been removed or reduced, and an air pressure switch ensures that heating current is not applied if the pressure is inadequate. The work, after treatment, is discharged on to a table 14 having rollers 15. The Provisional Specification states that the valve operating switches may be adjusted in the direction of movement of the pusher member, so that they are operated at an earlier or a later stage in the loader travel.

Title: Improvements relating to the catalytic desulphurisation of petroleum hydrocarbons
IPC: C10G45/24
Filed: 1950-03-14
Abstract: Petroleum feedstocks are desulphurized by passing in vapour form in admixture with hydrogen to at least three reaction zones in each of which the mixture is contacted with a sulphur-resistant catalyst, at such a temperature and pressure that the dehydrogenation of naphthenes is effected to such an extent to produce sufficient hydrogen to convert organically combined sulphur to hydrogen sulphide and to maintain the pressure in the reaction zone.  The hydrogen-rich gas mixture produced is recycled to constitute the whole of the hydrogen supplied to the reaction zones, the passage of the gas being discontinued to each zone in turn so that the catalyst therein may be regenerated.  The process may be carried out at a temperature of 750-800 DEG  F. and a pressure of 50-200 p.s.i.  The preferred catalyst is a mixture of the oxides of cobalt and molybdenum, compounds of cobalt, molybdenum and oxygen, or mixtures thereof.
