Title: A Character Generation System
Inventor: GARDNER GERALD MARVIN
IPC: G09G1/14
Filed: 1968-01-11
Abstract: 1,157,237. Character generators. STANDARD TELEPHONES & CABLES Ltd. 11 Jan., 1968, No. 1728/68. Heading G4H. A display or printer system in which corresponding portions of each character in a line of data are built up successively, that is by printing or displaying first the top row of dots for all characters and then each succeeding row of dots until a complete line of data is generated, includes at least one line store 2, 3 (Fig. 1) each of which stores a complete line of data, a character shape store 4, preset with a selected range of character shape by a line input unit, and read out under the control of an address register 5 connected to the line store(s) and pulsed by a character section counter 6 so that information representing the first row of data is fed to a matrix 11. The matrix 11 is pulsed by a character counter 14 so that the signals from the store 4 are read to the appropriate input channels of the printer or display before character section counter 6 is stepped to cause readout of the next row of data. In the embodiment described in which characters are formed on a surface of a printing drum 15 as charge patterns, the drum 15 is rotated by a motor 16 between each row of dots. Two line stores 2, 3 are used sequentially under the control of switches SW1, SW2. Line justification may be effected by including a width recorder which converts an input representing a character shape to an output representing its width, this output signal being fed to the character counter 13 to step it along the appropriate number of dot increments.

Abstract: 1531862 Storing hydrogen BILLINGS ENERGY CORP 23 Jan 1976 [21 April 1975] 02703/76 Heading F4P One or more containers 6 having a circular cross - section and filled with a hydrogen absorbent material is/are associated with means (a housing 2, as shown) for conducting a flow of heat exchange medium (h.e.m.) into contact with the container(s) 6 to enhance the absorption or desorption of hydrogen gas introduced or extracted through a manifold 30. The containers 6 in Fig. 1 are spaced by members 10 to improve circulation of the h.e.m. which is introduced at inlet 14. To improve heat exchange the containers 6 may have conduits extending longitudinally therethrough, and the containers may be frusto-conical with their broader ends upstream with respect to flow of h.e.m. to make uniform the transfer of heat along their lengths. Alternatively the containers or the conduits may have axially extending radial fins which increase in radial extent towards the downstream ends of the containers. In another arrangement the containers which have differing diameters are arranged transverse to the flow of h.e.m. with the containers of greatest diameter being at the upstream end and those of least diameter being at the downstream end of the arrangement. The absorbent material may be an iron-titanium alloy, mischmetal, or columbium.
Patent GB-469664-A (GB)
Title: Improvements in automatic switches for use in telephone or like systems
IPC: H04Q3/00
Filed: 1936-01-29
Abstract: 469,664. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., TAYLOR, R., and BAKER, G. T. Jan. 29, 1936, No. 2705. [Class 40 (iv)] In a selector in which the guard relay B is connected in series with the vertical magnet VM and is short-circuited at each impulse to operate the magnet, the initial operating circuit of the guard relay includes make-before-break contacts a1 of the impulse relay A and a separate non-inductive feed over a rectifier MRA. The circuit of the magnet includes contacts of the change-over relay C which is operated by B so that if the make-before-break contacts remain closed for an appreciable time due to the slow response of relay A on a long or leaky line, the magnet will not be operated. The rectifier MRA prevents the shunt circuit over the non-inductive resistance from interfering with the operation of the magnet. The selector shown has two sets of wipers which hunt simultaneously. On the closure of offnormal contacts N1, relays HA, HB operate and remain locked over their right-hand windings and test wiper P2 or P1 until an idle outlet is found, a self-interrupting circuit for the rotary magnet being closed over front contacts ha7, hb7. If wiper P2 first finds an idle outlet, HA releases removing a short-circuit from C which operates again to switch through the talking conductors and to hold HB over its left-hand winding. If P1 first finds an idle outlet, HB and HA release, C operates as before, and HA is re-operated over its left-hand winding to connect up the upper set of wipers. Busy signalling arrangements controlled by eleventh-step contacts are the same as described in Specification 459,872. Specification 391,123 also is referred to.

Title: Improvements in or relating to plasticised resins
IPC: C08L101/00
Filed: 1946-01-28
Abstract: Infusible phenol-, urea- or melamine-aldehyde resins are plasticized by the addition of polyacrylonitrile, e.g. 10 to 75 per cent (particularly 35 to 40 per cent) thereof, based on the weight of infusible resin.  The composition may be used in coating compositions, facing for laminated materials (for use as wall surfacings, table tops and trays) and for moulded articles such as corks and bottle caps.  In examples: an enamel consists of melamine-formaldehyde resin (prepared by alkaline condensation of 1 mol. melamine with 2.35 mols. of formaldehyde), polyacrylonitrile (prepared by polymerizing in alcohol-water medium in the presence of lauroyl peroxide), water, alcohol and zinc sulphide; paper was impregnated with this enamel and laminated by itself or on a plywood base to form panels; a moulding powder consists of melamine - formaldehyde resin and polyacrylonitrile.

Sausage meat 9 extruded into a casing 5, 5<SP>1</SP> bunched up on a feed tube 4 is twisted into links by rotation of the feed tubes 4 while the filler sausage length is held between grippers 12 while rubber &c. rollers 12 close in on the casing at the inner end of the tube 4 and so effect the rotation and twisting withdrawal of the casing being retarded by a rubber ring 19, Fig. 3. Thereafter the linked sausages proceed along a trough and are wound up helically on a reel 14. In threading the easing over the tube 4, the casing presses backward a sliding disc 7 against the pull of a tension spring 8 which later during filling urges the casing off the tube 4. After twisting the neck may be sealed by a clip clamped on the neck by dies 48, 49. The various operations are controlled in timed relation from a control shaft 16 rotated by a gear 17 from a gear driven from a disc gear 18 on the tube 4. To prevent the casing from slipping off the filling tube 4 too easily the front end of the tube is enlarged, Fig. 3, and an elastic ring 19 thereon retards the casing. In Fig. 5 the continuously rotated main shaft 30 carries a friction segment 31 which rotates shaft 31 carrying a drive belt to rotate the twist tube 28 a predetermined number of times. The grippers 39 are allowed to close on a sausage by a cam 37 rotated by a segmental can 32 operating a cranked lever 33 by its roller to hold the sausage during twisting. In Fig. 9 the filled sausage is squeezed by stirrups 58 to initiate the neck which is completed by rotation of the grippers 51 and the twist tube while the sausage is held in gripper 56. The grippers 51 have a lining 52 to retard the forcing forward of the casing 5 during filling. The feed tube has a detachable outlet 61 which further back the tube may be oval (63, Fig. 8, not shown) to retard the movement of the casing from the tube to compact the filling.
