Title: Method of and apparatus for manufacturing relief formes and duplicate copies in electrostatic printing processes
IPC: G03G9/08
Filed: 1967-03-08
Abstract: 1,148,845. Printing processes; selective printing. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 8 March, 1967 [10 March, 1966], No. 10909/67. Headings B6C and B6F. [Also in Division G2] A method of manufacturing relief formes and duplicate copies in electrostatic printing processes comprises developing the latent charge image with a hard coarse-grained material to form a relief image which, by the application of pressure and by means of carbon paper or inked ribbon, is reproduced simultaneously on a small number, e.g. three, copy sheets. Apparatus for performing the method comprises a record carrier 1 in the form of an endless web, on which an electrostatic printing apparatus 4 produces a latent charge image 5, the image being developed by being conducted by rollers 6, 7 through developing apparatus 8 comprising a trough containing a fluidized bed of coarsegrained material 9. The developing material may be glass, quartz, aluminium oxide, rock salt, sugar, hard metal or metal alloy, or hard carbon. The material is preferably of low density and may be metallized or carbonized. The grain size of the material is between 50 and 250 microns. The developed image, in the form of a relief image 10, may be fixed by heating- apparatus 14, and passes between rollers 11, 12 together with successive layers of carbon paper or inking ribbons 2-2<SP>11</SP> and copy sheets 3, 3<SP>1</SP>, the copy sheets being paper of density 30-50 gms/sq. mm. In a modification, the carrier comprises a thin, hard, insulating layer (16), Fig. 2 (not shown), on a conductive cylinder (15), a latent charge image being formed on the layer (16) and developed by passing through developing apparatus (8) comprising a metal trough conductively connected to the cylinder (15) and containing metallized glass spheres of a uniform diameter of 100 microns. The developed relief image (10<SP>1</SP>) passes between the roller (15) and an impression cylinder (12<SP>1</SP>) together with alternate layers of carbon paper or inking ribbon (2-2<SP>11</SP>) and copy sheets (3-3<SP>11</SP>). The relief image is removed from the layer (16) by a scraper (17) and the latent image destroyed by discharge apparatus (18) ready for a subsequent printing and copying cycle.

Title: Magnetic remanence data transfer systems
IPC: G11C19/06
Filed: 1963-03-20
Abstract: 959,012. Magnetic storage. devices. AMP Inc. March 20, 1963 [April 6, 1962], No. 11009/63. Heading H3B. In a magnetic shifting register using multiaperture cores 20, Fig. 1, each having clear, set and prime states of magnetic remanence obtained sequentially by pulsing a clear winding 26, an inlet winding 21, and a priming winding (not shown) which threads the same aperture as an outlet winding 28, and in which an output is induced in winding 28 by applying a further pulse to the clear winding, spurious outputs are prevented by arranging each core to have the least cross-sectional area on the line C, C passing through the outlet aperture. These spurious outputs are due to cumulative partial flux switching about the outlet aperture, and become apparent if during any cycle of operation a core is unset because of input pulse absence (binary zero registration). The reduced cross-sectional area may be obtained by having a larger outlet aperture, Fig. 3 (not shown), or by notching or otherwise reducing the cross-sectional area of the outer leg of the outlet aperture either on its edge at 38, Fig. 2, or on either face. Specification 899,367 is referred to.

Filed: 1922-04-24
Abstract: 198,522. Robinson, J., Crowther, H. L., and Derriman, W. H. April 24, 1922. Aerials. - An aerial system for directional transmission is arranged so that the effective radiation is due only to the vertical portions of the antennae. As shown, two aerials 3, 4 are crossed in such a way that the two horizontal portions lie parallel and close to each other, but extend in opposite directions so that the radiations from these parts are mutually neutralized. The vertical parts are spaced apart so as to secure a directional effect but do not otherwise interfere with each other. The system may be energized through a coil 5. Instead of being horizontal, the crossed parts may be inclined, and may be arranged in straight or angular conformation. The principle is also applicable to fixed or rotating aerial systems. It is based on the assumption that the horizontal electric component of the radiation is liable to introduce error in the directional effect, arising from reflection at the upper conducting layer of the atmosphere.

Abstract: 108,680. Schraders Son, Inc., A., (Assignees of Myers, E. van A.). March 21, 1916, [Convention date]. Tyre and like inflating valves. - A tyre valve casing is constructed in two parts permanently connected together, one part being formed of comparatively cheap metal such as iron or steel while the other part is made from rust-resisting material such as brass. In the form shown in Fig. 1, the major part A of the casing is made from cheap metal, copper or nickel plated on its exterior, and is recessed at its outer end to receive brass or copper insertion Q, containing all the working parts of the valve, and formed with the nipple C for attaching the pump. The insertion, which may be non-circular in section and with or without external flanges, may be screwed, or soldered, or pressed into the outer part and secured by turning the end of the casing over a flange formed on the insertion, or by making indentations along the flats on the casing. In a modification the bore F is lined with a sleeve either integral with or separate from the insertion Q. In a further modification the bore of the outer member is filled with solder or zinc and the zinc plug afterwards machined to obtain the necessary internal surfaces. In the form shown in Fig. 12, the part 22 is of iron or steel and is screwed against a packing 24 in an outer part 21 formed from drawn brass tubing. The form shown in Fig. 13 is constructed by electrically depositing a rust-resisting metal 43 on the inner member 40 and on a plug or core of lead or paraffin temporarily inserted in the member 40. The bore of the member 40 may be electro-plated by inserting a pin-shaped anode into the bore or by rapidly circulating the electrolyte through the bore. The brass insertion or casing may be cast in or around the member made of inferior metal. Two forms are also described showing the casing made entirely by drawing and pressing.

[Class 69 (i)] In meters for granular materials of the type described in Specifications 369,562 and 426,214, the drum is held from rotation while a compartment is being filled from a hopper 7 by an abutment G<3> engaging a buffer 62 on a pivoted beam 33, the latter being retained in the position shown by a hook 26 on a lever 18 engaging one end of a slot 28<1> in the beam. When the compartment is full, the grain heaps up in the hopper 7 and moves a pivoted member 12 having a pivotal connection with the lever 18 ; the latter is thus rocked to disengage the hook 26 and the beam falls to free the abutment G<3>, the extent of fall being limited by a hook 50. The drum then turns until the abutment G<3> acts on a member 33<a> to restore the beam to its initial position. During the last portion of the upward movement of the beam, one end of its slot 28 acts on a rounded portion 27 and returns the lever 18 and member 12 to their initial positions. Should the discharge bin 43 be too full, the heaped up material moves a plate 38 against the action of a weight 52 to cause a tongue 53 to move into position to prevent the descent of the beam 33.
