Title: Improvements in elevating trucks
IPC: B62B3/06
Filed: 1919-09-03
Abstract: 154,983. Lovejoy, R. M., and Lewis-Shepard Co. Sept. 3, 1919. Hand-trucks. - In hand-trucks having a load-carrying platform adapted top raised by longitudinal movement thereof, after being run beneath the load, the raising movement is effected step by step by oscillating the steering-handle, and a toggle-link locking-means holds the platform in the completely raised position. As shown in Fig. 1, the platform 25 is connected by links 27, 32 respectively to the side members 1 of the underframe and to the tubular cross-member 12, which is fixed to the rear ends of the members 1 by brackets 9, 10. The rear axle 13 is free to rotate in the member 12, undue wear at the underside of the parts 19 of the axle forming the wheel journals, being thereby avoided. A link 36 extends from the middle point of the front cross-member 26<a> of the platform 25 to a toothed sector 37 pivoted at 39 to the arched member 4 of the underframe. The propelling and steering handle-bar 43 is pivoted at 44 to the head 41 of the pivot 6 of the steering-wheel 8. The pivot 6 turns in the arched member 4. Pawls 52, 45 are pivoted respectively to the handle-bar 43 and the head 41. By oscillating the handle-bar on its pivot 44, the platform 25 is raised by the pawl 52, and is retained at each step by the pawl 45. When the platform is fully raised, togglelinks 58, 59, pivoted respectively to the sector 37 and the underframe 1 are straightened and are urged against a stop 68 by a spring 67, lever 64, and link 63 so as to lock the platform in the raised position. The pawl 45 is connected by a link 47 to a hand-lever 48 on the handle-bar 43, and this pawl and the pawl 55 have contacting guide surfaces 56, to cause proper engagement of the pawls with the sector 37 and whereby both pawls can be disengaged from the sector by the hand-lever 48. The toggle 58, 59 can be broken to lower the platform by a pedal 66 on the lever 64. A dash-pot 70 connected to a cross-member 72 of the underframe and to the platform member 26<a> checks the descent of the platform. Cooperating inclines on the platform and underframe may be substituted for the links 27, 32.

Web-feeding apparatus for use in an addressing machine comprises endless tractor members 2, Fig. 2, carrying feed pins 2a for engagement in perforations in a web w, Fig. 4. The members 2, Fig. 2, are mounted on rods 3 driven through gearing 5, 6, 7, 8, and 9, Fig. 3, by a rotary solenoid 9 as described in Specification 789, 605 to effect line spacing and feeding of the web, a gear 12, driving gear 8 through, gears 10, 11 is driven through a solenoid-actuated clutch, not shown, by a motor M which effects a long feed in the manner described in Specification 848,918. Discs 17, 18, Fig. 2, on a shaft 16 rotated once for each form length of the web, operate switches S<SP>1</SP>, S<SP>2</SP> in the manner described in Specification 777,491. The web w, Fig. 4, has form lengths a, each having a heading area x, e.g. for a name and address, and a data receiving area X, e.g. for names of employees, to be printed line by line, y being the first line and z the last line of the area X. Should the amount of data to be printed in the area X of one form exceed the space available, the switch S2, Fig. 2, is operated before a switch S3 (Fig. 5 not shown). The switch S<SP>3</SP> is arranged for operation by a tag on a printing plate, not shown, placed at the end of a series of plates for printing successively under one heading. Closure of the switch S<SP>2</SP> causes the clutch solenoid to remain energised until the line y of the next form arrives in printing position, whereupon line spacing, initiated by closure of switch S<SP>1</SP>, Fig. 2, follows until line z is reached. If switch S <SP>3</SP> closes before line z is reached and thus the switch S2, the clutch is engaged and a solenoid-operated brake, not shown, is released to cause a long feed until switch S<SP>1</SP> closes on arrival of the heading area x at printing position. Closure of the switch S<SP>1</SP> causes deenergisation of the clutch solenoid and energisation of the brake solenoid. The energisation of two solenoids 7 and 9 (Fig. 5 not shown) which disengage, the clutch and apply the brake respectively is controlled by rotary switches W, W<SP>2</SP>, W <SP>3</SP> rotated in steps by a solenoid RS and by a manually set selector switch SW, the setting of which determines the number of stepping movements during the feed of the heading area of the form.

Title: Toy railway track system
IPC: A63H19/30
Filed: 1959-06-25
Abstract: 893,456. Toy railway controllers. MARC & CO. Ltd., LOUIS. June 25, 1959 [June 25, 1958], No. 21915/59. Class 132(3)  Toy railway track of the two-rail type is provided with an accessory circuit controller comprising contacts which are closed when a ramp located between the rails is depressed by a train passing over the ramp. In Figs. 12, 16, a base 12, preferably one-piece moulded of insulation material, has a ramp 22 of insulation material or thin sheet metal coated with insulation, the ramp being located by yokes 70 preferably integral with the base. Two pairs of normally open, spring contacts 36, 38 and 42, 44 are provided near the centre of the base, upper contacts 36, 42 being formed from a single piece of thin spring metal, and the lower contacts, which have points 40, 46, being separate from each other; eyelets secure the contacts to the base. Spring metal connectors 54 extend from the contacts to the side of the base and the stripped ends 60 of connector wires 62 are held by pressure of the connectors 54 against the base, Fig. 15. The rails 14 comprising inverted channels of sheet metal are secured on ridges 98 of the base by means of tongues. The vehicles of the train have operating projections, the spacing of which is greater than the length of the ramp. Thus only one projection bears on the ramp at any time and only one pair of contacts are closed at a time when the train passes over the ramp. A two-light flashing signal 30, connected to a power supply L 1 , L 2  thus gives an intermittent or flashing action. Additional yokes 110 on the base permit a ramp longer than the spacing between the vehicle projections to be provided. In such an arrangement, two projections bear on the ramp much of the time and both pairs of contacts are closed. The desired result is further assured by connecting the two pairs of contacts together. Instead of the rails shown, solid metal rails fastened by U-shaped staples may be used.

Title: Improvements in or relating to the manufacture of linear nitrogen-containing polymers
IPC: C08L75/00
Filed: 1939-08-03
Abstract: Linear polymers of high molecular weight are prepared by reacting a bis chloroformic ester of a glycol with a compound containing as sole reactive radicals two amino groups until the product has film-forming properties.  For products of particularly high molecular weight suitable for example for filaments, equivalent proportions of the reactants are used.  The bis chloroformic ester may be prepared by treating with carbonyl chloride, a glycol, e.g. ethylene glycol, di-, tri-, tetra- or penta-methylene glycol, or di- or tri-ethylene glycol.  Suitable diamines are ethylene and propylene diamine, 1-3-diamino propane, pentamethylene and hexamethylene diamine, 2-5-diamino hexane and phenylene diamines.  Reaction may be at normal temperature or heat may be applied especially in the later stages of the reaction. Completion of the reaction may be assisted by reduction of the pressure or by the presence of alkaline materials.  Solvent or diluent may be present and may be distilled off in the later reaction stages.  Reaction at elevated temperature is preferably performed in nonoxidising atmosphere, e.g. nitrogen.  The products may be formed into filaments or films, if desired, with the aid of plasticisers. These materials may be stretched in known manner.
