Patent GB-305101-A (GB)
Abstract: 305,101. Deutsche Gold-und Silber- Scheideanstalt vorm. Roessler. Jan. 30, 1928, [Convention date]. Addition to 280,554. Inhalers and respirators. - The process of the parent Specification is modified by employing a larger amount of water for the hydration of the alkali metal peroxides or mixtures thereof, the amount used being preferably 10-15 per cent but not more than 23 per cent, uniform distribution being obtained by finely dividing the peroxides and by thorough mixing, the water being introduced in atomized or vapour form or as snow or by spraying, the mixture being effected in rotating drums or tubes. The peroxide may be dusted into an atmosphere containing water vapour. The mixing apparatus may have means for rapidly removing the heat of hydration. The hydrated preparations may be heated to increase their stability, low temperatures, e.g. 45-50‹ C., and a longer heating period being used for the more reactive preparations and higher temperatures, e.g. up to 150‹ C., and a shorter heating for the more compact and less reactive materials. Very reactive preparations may be heated at one spot whence the heat is transmitted throughout the mass. The hydrated substances may be shaped into small pieces, pressure being used, if necessary, and then stabilized by heating; heating may additionally be applied prior to shaping. Large-shaped pieces may, after heating and cooling, be reduced to the size required for use and the powdered waste also produced may be mixed into fresh material. Inert substances such as kieselguhr, silicic acid and common salt may be added to the preparations. Catalysts such as oxygen compounds of copper and manganese may be added during the production of the peroxides or at other stages in the preparation. Specification 9461/00, [Class 2, Acids and salts, Organic &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also obtaining uniform mixture of the peroxide and water by finely dividing the peroxide; the use of balls &c. for grinding in the rotating drums, tubes, etc.; and the subjection of the hydrated products to a milling operation. This subject-matter does not appear in the Specification as accepted.

Title: Paper feed device in duplicating machines
Inventor: BONSCH FRANCOIS RODOLPHE HENRI
IPC: B41L11/12
Filed: 1957-10-01
Abstract: 826,302. Toothed gearing. SOC. DE MECANOGRAPHIE JAPY. Oct. 1, 1957 [Oct. 10, 1956], No. 30726/57. Class 80 (1). [Also in Group XVI] A rotary drive for intermittent driven rotation comprises a driving pinion 26 with a complete set of teeth which engages simultaneously with two coupled pinions 27, 28, the pinion 27 being keyed to, and the pinion 28 being loosely mounted on, the driven shaft 1, these coupled pinions each having a non-toothed sector 27a, 28a, respectively, of sufficient size to prevent driving by the pinion 26, and being connected together by a pin 30 and slot 35, or other lost-motion coupling, permitting each of the pinions to make a limited angular movement with respect to the other. The two non- toothed sectors 27a, 28a are always staggered angularly in all the possible positions of the lostmotion coupling. Discs 31, 32 (Fig. 3, not shown) fixed on each side of the pinion 26 are of slightly larger diameter than the latter, and have notches 31a, 31b and 32a, 32b, respectively, therein which co-operate with lugs on U-shaped pieces 33, 34 fixed, respectively, on the non-toothed sector portions of the pinions 27, 28. In operation, when the pinion 26 is driven by a crank M, the lugs on the pieces 33, 34 co-operate with the discs 31, 32 to retain one or the other of the respective pinions 27, 28 stationary when the non-toothed sectors are opposite the pinion 26, and starting impulses are imparted to the pinions 27, 28 by the pin and slot means 30, 35 when the lugs of the pieces 33, 34 are able to mate in the respective notches 31a . . . 32b in the discs. Thus the continuous rotation of the pinion 26 by the crank M results in stationary periods of the driven shaft 1, and the pinions 27, 28 are not stationary at the same instant. The invention is described as applied to a duplicating machine (see Group XVI).

Title: Reel control system
IPC: B65H59/38
Filed: 1973-06-28
Abstract: 1430845 Coiling wire GENERAL ELECTRIC CO 28 June 1973 [30 June 1972] 30772/ 73 Heading D1T A control system for depositing linear material in continuous layers into a rotating receiving means, each layer forming a coil approximating to an Archimedes spiral, with the spiral direction reversed on alternate layers, comprises means 100 for continuously producing a first signal proportional to the speed of the product, means 300 for establishing a spiral constant and for continuously producing a second signal proportional to the desired coil convolute radius as a function of said first signal and said spiral constant; means 200 for dividing the first signal by the second signal to produce a reel speed reference signal; and means 600 for controlling the angular motion of the reel 800 in response to said reel speed reference signal. Radii limits. The output of the radius generator 300 is connected to a detector 400 which detects the inner and outer radii limits and reverses the direction of radius change each time the inner and outer radii limits respectively are reached. A rheostat (301), Fig. 5b (not shown) is included in the radius generator and is used to establish the spiral constant. Torque Regulation. A torque programmer 500 sends a signal T to a torque regulator 700 regulating the torque on the reel 800. The signal T is proportional to the torque required to overcome inertia. The torque programmer 500 is also connected to an input from a device 1000 providing a signal proportional to the actual reel speed. Speed Control. The speed regulator 600 compares the reel speed reference signal 200 with the reel speed signal from the sensing device 1000. The resulting error signal is fed into a torque regulator 700 which modifies the torque as required to maintain an accurate speed of the reel 800. Rate Limit Reference. A rate limit reference 900, which limits the second derivative of the desired coil convolute radius with respect to time to produce a smooth response for reversal of the spiral constant is connected to a second input of the radius generator 300 and is further connected as a third input to torque regulator 700 to limit the torque rate. Thus, the torque regulator 700 regulates the torque on reel 800 in accordance with torque programmer 500, speed regulator 600 and rate limit reference 900. The circuit of Fig. 4 is particularly described with reference to Figs. 5a to 5d (not shown).

Title: A Hydraulic Circuit Arrangement For A Vehicle Driven And Steered Hydraulically
IPC: B60K17/10
Filed: 1967-07-05
Abstract: 1,155,908. Hydrostatic transmission; hydrostatic brakes. ORENSTEIN-KOPPEL UND LUBECKER MASCHINENBAU A.G. 5 July, 1967 [5 July, 1966], No. 30875/67. Headings F2D and F2E. In a hydrostatic transmission for a motor vehicle wherein a pump 17 supplies pressure liquid through a reversing valve 18 to a motor 15, overrun of the motor is prevented by a throttle valve 1 in the return line 14, 22 from the motor and the valve 1 provides increased throttling of the motor discharge as the pump supply pressure 19 decreases. The throttle valve 1 has a spool 3 slidable in a casing 1 having grooves 6a, 7a connected to the return lines 14, 22. The pump supply pressure acts through a line 16 on a step 24 of the valve spool 3 to move the latter up against the action of a return spring 5. When the pump 17 drives the motor 15 the pressure in the lines 16, 19 is high and the valve spool 3 moves up to the position shown in which it permits free flow between the grooves 6a, 7a through an annular groove in the spool 3. When the motor 15 tends to overrun the pressure in the lines 16, 19 falls and the spring 5 moves the spool 3 down to a position in which a restricted flow between the grooves 6a, 7a is through throttling bores 8, a central base 10 and a radial bore 12. The motor is thus braked and prevented from overrunning. When the pump is stopped the spring 5 moves the spool 3 down to a position in which it blocks flow between the grooves 6a, 7a and thus prevents flow through the motor and provides a parking brake.
