Title: A process and device for registering sheets in multiple colour printing
IPC: B41F21/10
Filed: 1929-07-03
Abstract: 339,275. Kings Patent Agency, Ltd., (Schnellpressenfabrik Frankenthal Albert et Cie Akt.-Ges.). July 3, 1929. Rotary machines.-In a multi-colour printing- machine in which sheets are printed with superposed impressions and the sheets are passed between the impressions from one impression cylinder D to another by means of a transfer cylinder U, correct registration of the impressions is obtained by giving the sheet a circumferential movement in the course of the transfer of the sheet. If desired a lateral motion may also be given to the sheet. The transfer cylinder U is fitted with a gripper support B comprising a bottom member 7, side members 5 in which a gripper shaft 1 is mounted, and an upright member 4 against which the tips 3 of the gripper 2 press. The support B is guided by rails 27, 28 and is pressed by springs 31 against stop screws 32 which limit the movement of the support in one direction. The cylinders D, U are geared together, and in their rotation sectors 8, 11 fitted to the support B engage similar sectors 9, 12 which are circumferentially adjustable on the cylinder D. The circumferential adjustment is effected by screws 21 engaging nuts 23 integral with the sectors 9, 12 in which a gripper shaft 24 with grippers 25 is mounted. The sectors 9, 12 are held in adjusted position by screws 17, 18, and the gripper support B adjusts itself automatically to the position in which the grippers 25 are set owing to the engagement of the gears 9, 12; 8, 11. The foremost teeth of one set of sectors are preferably made thinner than the remaining teeth. The gripper support B is preferably constructed so that it can be adjusted laterally while in motion in order to secure correct lateral register of the sheets. The support B is held in place by bars 27 which permit it to move laterally when a projection 35 on it engages a roller 37 which is carried by a threaded bolt 38 mounted in the frame G in such a manner that it can not rotate. A nut 39 operated by a hand-wheel 40 adjusts the position of roller 37 and thus controls the lateral position of the sheet at the time of transfer. The invention may be applied to the three-colour printing-machine described in Specification 252,908, and may be applied to offset machines, and the movable gripper may be arranged on a sheet-transfer cylinder or on an impression cylinder.

Abstract: 933,415. Making electric heating elements; coiling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd., and WESTMINSTER ENGINEERING CO. June 1, 1962 [June 8, 1961], No. 20768/61. Classes 83 (2) and 83 (4). A method of manufacturing a convoluted sheathed wire electric heating element ineludes winding a sheathed wire heating element of linear form on to a former, having a profile arranged to impart the required shape to the element, at least the surface of the former being of electrically insulating material, and while the element is on the former passing an electric current through the sheath to raise the temperature thereof to a degree and for a period sufficient to remove resilience from the sheath, and if necessary anneal the material thereof, whereby, on cooling and removal of the element from the former, the convoluted element retains the shape which has been imparted to it. The end of a linear sheathed wire heating element is bent out of alignment with the rest of the element and inserted into a slot in the apex of a former 1 having a frustoconical metal bore the profile of which is provided by a spiral ledge formed thereon and covered with electrically insulating material. A pneumatic device 17 then urges a roller 15 to press the element against the spiral ledge while the former 1 is rotated and moved axially, to wrap the element therearound, by an electric motor rotating a shaft 4 threaded in a fixed nut 6. When the winding is completed a clamp 21 is lowered to hold the coiled element in the former 1. The clamp may be in the form of an open inverted V or as shown comprise a flat plate urged down by pneumatic means and having spring mounted plungers 26 thereon one of which engages the outer turn of the coiled element. An electrode 33 is then moved by a pneumatic device 36 to engage the end of the outer convolution of the coiled element and an electrode 47 is moved by a pneumatic device 51 to engage the end of the element which projects down through the slot in the former 1. The electrodes are conveniently secured to the secondary windings of a transformer and a current is passed through the sheath of the element to raise it to red heat to remove the resilience therefrom. The apparatus may be operated automatically under control of a timing circuit including a shaft with cams thereon. The former 1 may be collapsible axially by the clamp 21 before the heating takes place.

[Also in Divisions B3 and G4-G6] An element for use in fluidic circuitry is formed by die stamping one or more fluid flow channels in the surface of a component of the element. The channels are not stamped right through the component. The die is made of wire and may be pressed into one component or pressed between two superposed components, and a fluidic element formed from a component and a flat plate or by two superposed components joined by glue, screws, clips, rods or mutually engaging ribs and holes. The channels may be formed as resistances using wire dies in which the length is at least ten times the width or a channel made with a chamber near its centre to form a T-filter. A number of elements may be arranged in a stack and the channels connected by drilling holes in the sides and edges of the elements. The die is made of hardened carbon steel drawn by the wet process and the component made of aluminium, brass, copper or plastics material. In operation, the die is either mounted on a steel backing plate for pressing one component or fixed between two components by mounting holes, in both cases an hydraulic press being used. The channels may be formed of circular, polygonal, semi-elliptical or semicircular crosssection depending on the die shape. In another embodiment the die is a steel plate. Alternatively whole fluidic circuits can be stamped by the method described.

Filed: 1927-08-12
Abstract: 276,657. Soc. Anon. des Anciens Etablissements Bernard Verrerie de Bagneaux. Aug. 27, 1926, [Convention date]. Hydrostatic apparatus. - In a process for grading objects according to their weights, the objects are placed on an isolated float or a float belonging to a group of floats which sinks more or less according to the weight of the object and thus brings the object opposite to a series of inlets leading to the compartments of a grading device. A row of floats E of the hydrometer type is arranged within a tank B, the liquid contained therein being maintained at a constant level by means of a feed pipe and overflow. Each float is situated within a conduit I to damp the oscillations. The platforms H of the hydrometers are situated near the inlets M of inclined shoots N leading to boxes or compartments O which may contain liquid or solid cushioning material. In using the apparatus, the operator places the objects one by one on the platforms H and when the last platform has been loaded returns to the first. platforms (whose oscillations have meanwhile had time to damp) and pushes the objects successively into the shoots N, whence they fall into the grading boxes O.
