Ticket printing apparatus comprises a ticket destination printing unit, a fare printing unit controlled by a scanning device responsive to the introduction into the apparatus of a selected one of a plurality of individual sheet or card form data storage devices, each of which bears ticket information, and individual protective frames for accommodating the respective data storage devices. Each frame has one side removable, pivotable or slidable to permit interchanging of the data device when there are tariff alterations, and has a cover-plate on the face remote from the scanning surface. The data devices may be cardboard punched cards, or made of plastics material, or sheet metal, or in the form of printed circuits for electrical (capacitative) scanning. Each frame or data device may carry an inscription referring to the data stored in the device. Scanning may also be achieved mechanically, magnetically or electrooptically. The apparatus, which may be of the selectable printing plate kind, has a printing unit for ticket type (single, return, class &c.). Tickets are dispensed from a magazine subdivided for tickets of different colours. One data device may be provided for each combination of destination and ticket type. Alternatively, one data device may carry fare information for all types of ticket corresponding to a given destination. In the former case each data device carries a data item for controlling the dispensing of an appropriate ticket from the magazine and for adjusting the printing unit for ticket type. In the latter case the ticket type is selected, e.g. on a keyboard. The keyboard controls the ticket dispensing, and the printing unit for the ticket type and also adjusts the scanning device to pass only the fare data corresponding to the selected type of ticket, to the fare printing unit. In one embodiment, each frame is connected to a ticket destination printing plate adapted to be inserted into the machine, and the scanning device has a guide for the frames. The machine has separate printing stations for the ticket type, departure station, destination, fare, date and serial numbering. Printing of the ticket type is effected before the printing of the destination and fare. In a second embodiment the magazine is in the form of a turntable with vertical ticket compartments, and the destination printing plates are arranged on the periphery of a drum. A guideway extends from the magazine for leading tickets successively to the printing units. The magazine and the printing units for ticket type, destination and fare, are adjusted by driving devices including geared motors, shifting segments, shift clutches and locking devices, under the control of the scanning device.

Title: Improvements relating to slicing machines
IPC: B26D7/06
Filed: 1927-12-02
Abstract: 294,418. Berkel, J. C. van. Dec. 2, 1927. Cutting slices in succession.- The feed-nut of a slicing-machine is adapted to be forced into engagement with the feed-screw 7 by the inclined-plane action of a member which is slidablv mounted on a block 10 carrying the feed-table 5 and slidably arranged relatively to the screw, the member being acted on by a spring mounted on the block. The block is slidable on a bar 9 arranged above the screw, and the table 5 is secured on the block by the means described in Specification 294,419. Two feednut segments 15. Fig. 3, or a nut segment 15 and a smooth guide member 15<a>, Fig. 9, are carried by levers 16 arranged above and below the screw 7 respectively, the levers being located between jaws 18 formed on the block and being pivoted at their inner ends to the jaws. Rollers 21 fitted at the outer ends of the levers 16 ride along inclined tracks 22 presented by the inner surfaces of branches 23 of a member 24 guided in a recess 26 formed in the block, the member 24 being pressed outwards by a spring 27 tending to maintain the feed-nut in engagement with the screw. The rollers 21 are maintained in contact with the tracks 22 either by engaging a groove, as shown in Fig. 9, or by a spring 20, Fig. 3. In the form shown in Figs. 2 and 3, a lever 33 has a spindle 34 pivoted on a pin 33<1> on the block and is movable between limits defined by shoulders 35 on a member 36 formed on the spindle 34, the shoulders coacting with a projection 35<1> on the block. The member 36 is formed with cam surfaces 37, 38, 39 cooperating with a roller 40 mounted on a lever 30 pivoted to the block at 31 and co-operating with a projection 32 on the member 24. When the lever 33 is in its intermediate position, the roller 40 being then located at the junction of surfaces 37, 38, the spring 27 acts to maintain the segments 15 in engagement with the screw 7. If the lever is moved to one extreme position, in which the member 36 occupies the position shown in Fig. 2, so as to separate the segments 15 from the screw, the lever returns to its intermediate position when released. If, however, the lever is moved to its other extreme position, the roller 40 engages the surface 39, which may be formed with a slight depression, and the lever is retained in that position when released, with the segments 15 out of engagement with the screw. The block 10 is provided with a cover plate 51 through which the spindle projects. In the form shown in Figs. 8, 9, a lever 64, pivoted at 65 to the block, has a slot 66 engaging a pin 67 on the member 24. By pulling the lever towards a handle 62 secured to the block, the nut 15 is separated from the screw and the table 5 may then be moved by the handle 62. The jaws 18 are slidably supported by a rib 78 formed on the carriage 3a or on the frame, depending on the type of machine, which rib engages recesses 79 in the jaws, or vice versa. Specification 263,031 also is referred to.

Filed: 1934-11-12
Abstract: 447,272. Compound fabrics. BRITISH CELANESE, Ltd., 22, Hanover Square, London. Nov. 12, 1934, No. 32515. Convention date, Nov. 14, 1933. [Class 140] A flexible laminated material is formed by superimposing layers of textile fabric containing yarns of an organic derivative of cellulose and foil or sheeting of an organic derivative of cellulose, with a layer of foil or sheeting on each outer surface of the assembly, and causing the layers to adhere together. Adhesive is preferably effected without the aid of adhesives, the surface of one of the layers being softened by heat or by a solvent and bonding effected by pressure. Thus a fabric may be interposed between two layers of foil and united by heat and pressure. An adhesive, e.g. a thin layer of liquid or powder comprising an organic derivative of cellulose and a plasticizer may, however, be employed, or, alternatively, lacquers containing nitrocellulose, phenol - aldehyde resin, diphenylol propane - aldehyde resin, vinyl resins, casein resins, &c., dissolved in a volatile solvent. The fabric may be woven, knitted, knotted, welted or braided and may be composed wholly or partly of yarns or filaments of organic derivatives of cellulose. The yarns may contain pigments, fillers, dyes, fire retardents, softening-agents, sizes, and lubricants; examples are given. The foil or sheeting preferably contains plasticizers and may also contain colouring and other effect materials. The products are waterproof and may be employed for shower bath curtains, pocketbooks, moisture-proof bags, raincoats, &c. The material may be cemented to wood, enamelware, &c.

Title: Improvements in or relating to spring assemblages
IPC: F16F15/073
Filed: 1945-12-04
Abstract: 617,076. Temperature-responsive actuating elements. WIGAN, E. R. Dec. 4, 1945, No. 32770. [Class 64(ii)] [Also in Groups XX, XXXII and XXXVII] A spring assemblage comprises a bimetallic or other spring member resilient in a direction transverse to its length, two anchorages spaced apart and rotatably adjustable about parallel axes, means for fixing the anchorages in their adjusted angular positions, at least one of the anchorages being arranged to permit adjustment of the spring transversely to the axis of rotation of the anchorage and means for clamping the spring in the latter adjusted position. In the construction shown in Fig. 1, a blade spring 1 of length l, is adjustably secured in anchorages 2, 2<1>, the distance apart x, of which, and the angular setting of which about an axis perpendicular to the plane of the mounting plate 4, are adjustable to control the behaviour of the spring under loads applied thereto, such as at 6. By suitable adjustment of the ratio l/x and/or the couples applied by the anchorages the stiffness of the spring under such loads may be reduced to zero or made negative to produce a snap-action spring. In the latter case the spring may be of bi-metallic form so that a snap-action occurs at a particular temperature. A spring of known negative stiffness may be coupled to an unknown spring of positive stiffness to effect calibration of the latter. In the construction shown in Fig. 3 the invention is applied to give parallel motion to a carriage 7 which is constrained to move rectilinearly along an axis xx due to its suspension by the springs 9, 9<1>, under the action of a lead screw 8. In Fig. 5 the carriage 7 is suspended by a single pair of springs 9. In Fig. 6 (not shown) the two springs of the construction shown in Fig. 3 are each of semi-circular shape and are combined at mutual anchorage points to form a single spring of oval shape, which when unstrained is circular. Other applications are to vehicle springs and to relay armatures.

Filed: 1939-12-27
Abstract: 587,435. Grinding cutting edges. SOC. GENERALE DES METAUX NON FERREUX. Dec. 27, 1939, No. 32872. Convention date, Dec. 24, 1938. [Class 60] The cutting edges of tools are simultaneously ground (or polished) and hardened by a wet process wherein an electric current is passed between the tool 4 and the grinding wheel 1 during operation. The grinding wheel may be formed of carbon, silicon, tungsten, hard metals &c. adapted to become incorporated in the surface of the tool under treatment, the hardening being assisted by the use of hardening salts in the liquid 9 in which the wheel is immersed. The tool and wheel form the positive and negative electrodes respectively of a circuit controlled by a rheostat 7. During operation, each point of the tool edge is raised to a temperature close to its melting point and the material of the wheel acts in conjunction with the wetting liquid in producing the hardening. In a modification, Fig. 2, the wheel is made of felt which is permeable to liquid to render it conducting. The whool shaft 12 is hollow and has holes 11 through which liquid passes from the shaft to the material of the wheel. The wheel is rotated at high speed so that a fine surface finish is imparted to the tool.
