Abstract: 770,104. Making wire articles. GENERAL MOTORS CORPORATION. June 10, 1955 [June 15, 1954], No.16741/55. Class 83 (4). A method of forming a straight wire into a configuration of three-dimensional extent comprises the steps of gripping the wire to prevent its axial rotation, bending the wire in a first plane to present a portion of the wire in an angular relation to the longitudinal axis of the wire, axially rotating the wire to present the previously bent wire portion in a plane other than the first plane, and then bending the wire in the first plane. A straight wire blank 3 is bent to form an accordion fold spring 2, Figs. 1 and 22, comprising two accordion-fold shaped portions 4, 5 connected by a cross-member 6, each portion 4, 5 including three elongated arms 7, 8, 9, connected to each other by crossmembers 10 and 11, and end portions 12. The straight wire 3, positioned in symmetricallydisposed bending devices 19-25, 19<SP>1</SP>-25<SP>1</SP>, Fig. 3, is gripped midway by clamps 18. The ends of the wire are then bent up, by pins 26 of the benders 19, 19<SP>1</SP>, around vertically shiftable cores 27. The wire is next bent about cores 29 of the bending devices 20, 20<SP>1</SP> and then back over cores 31 of the benders 21, 21<SP>1</SP>, Fig. 9. The wire is then axially rotated through an angle 33, Fig. 12, and then bent, in the first plane, around cores 35 of the benders 22, 22<SP>1</SP>, Fig. 13, and then about cores 37 of the benders 23, 23<SP>1</SP>, Fig. 15. The wire is then rotated axially through an angle 39, Fig. 18 in the opposite direction from the first rotation. The wire is then bent about cores 41 of the benders 24, 24<SP>1</SP> and finally about cores 43 of the benders 25, 25<SP>1</SP>, Figs. 21, 22.

Title: Improvements in or relating to grinding mills
IPC: B02C7/00
Filed: 1928-06-09
Abstract: 291,803. Macao-Walzenm³hlen-Ges. June 9, 1927, [Convention date]. Conical mills; disc mills.-A grinding-mill for paints &c. is contained in a casing 8, Fig. 1, in which is an annular grinding disc 16 with which co-operates a plurality of planetarily-driven grinding-discs 15 which are mounted eccentrically on spur wheels 6 attached to rolls 2. The rolls 2 engage with a central roller 1. mounted on the driving-shaft 3 and with a lining 9 on the casing, the spur-wheels 6 engaging with spur-wheels 5 on the centre roll and with circular racks 7. The rolls 1, 2 and lining 9 may be cylindrical or conical and may be made of porcelain. The disc 16 may slide in the casing 8 and is provided on both faces with tangential grooves. The opposite face of the disc 16 is engaged by a disc 19 mounted on a boss 20 slidable on the shaft 3. The feeding-device comprises a hopper 10 with conical valve 12 adjustable in position by a handwheel 14, the material being fed by a worm 11 which may be arranged horizontally around the shaft 3. The material passes along the rollers and through the teeth of the spur-gears 5 - - 7, that part of the disc 15 immediately under the teeth of the spur-wheel 6 being recessed at 17, Fig. 3, and provided with holes 18 for the material to pass to the other side of the disc. Due to the movement of the discs 15 from the position shown in Fig. 3, to that shown in Fig. 4, there is effected a pumping action which forces the material through a pocket 21 in the disc 16 to the space between the grinding-discs 16, 19 where it is further ground and discharged through the orifice 27. Adjustment for pressure is obtained by a spring 22 mounted in a sleeve driven by the pulley 4, the sleeve driving the shaft 3 by a cotter b. The spacing of the rolls is determined by the adjustment of the screw 24 mounted in a screwed bush 25 and contacting with the end of the shaft 3. Adjustment between the discs 16, 19, is effected by screwing in the bush 25 which slides the boss 20 along the shaft 3. If the disc 16 is slidable in the casing 8 then adjustment of the bush 25 effects a variation in pressure between the discs 15, 16.

Abstract: 594,851. Fluid-pressure servomotor-control systems. WATSON,C. D., and VENNING, R. B. H. July 2, 1945, No. 16815. [Class 135] In a hydraulic servomotor, for operating aircraft control surfaces of the kind in which a manual control column &c. actuates a valve controlling liquid supply to the motor 1a, a pilot plunger 8 within the motor plunger is subjected to the liquid pressure therein and is connected to the column whereby the pilot is able to " feel " the load on the control surface. Recesses 12a, 12b in the' pilot plunger on opposite sides of an abutment fixed to the plunger 1a, communicate through passages 16, 17 with the motor cylinder. Initial movement of the control column forces liquid from one or other of the spaces 12a, 12b into the motor cylinder to start movement thereof, continued movement being effected by liquid under. pressure supplied through the distributing valve actuated by the column. Said liquid pressure also acts in the pilot piston and is transmitted thereby to the column. Should the power fail, the motor can be operated mechanically by engaging a catch 18 between the motor piston and a member 6 connected to the column.

Title: Improvements in or relating to methods of duplicating and duplicating machines for performing the same
IPC: B41L1/34
Filed: 1959-05-19
Abstract: 883,443. Coated and impregnated papers used in copying. RITZERFELD, W., and RITZERFELD, G. May 19, 1959 [May 20, 1958], No. 16947/59. Drawings to Specification. Class 96. [Also in Group XVI] A method of duplicating copy sheets or cards from a printing master sheet having initially non-staining or initially only slightly staining image areas comprises the steps of attaching the printing master sheet to the printing drum of a rotary duplicating machine and applying, otherwise than by transfer from the copy sheets, an activating liquid to the image areas by rotation of the drum, a moistening device applying activating liquid directly to the printing master sheet or moistening an activating sheet which is attached to the drum in contact with the master sheet for at least one revolution of the drum before printing. The activating liquid may be alkaline or acid, or have as its active constituent a salt or an oxydizing agent such as potassium permanganate and a neutral " copying " liquid may be used for damping the copy sheets. According to Example I a printing master sheet having a silver halide emulsion of the auto reversal type in a layer which also comprises a slightly coloured, finely-dispersed, water-insoluble dye former, e.g. the leuco base of malachite green, is prepared by being exposed by reflection to a positive original. The master sheet is developed and the leuco base is oxidized to a dye base in a separate device outside the duplicator. When attached to the printing drum of the duplicator the master sheet is activated by being moistened with a 4% formic acid aqueous solution. The insoluble dye base is thereby converted into a water- and alcohol-soluble dye salt. The copy sheets are damped with alcohol. The master sheet may be reactivated when the quality of the copies deteriorates. According to Example II the activating acid is dilute amido-sulphuric acid.
