Filed: 1927-06-20
Abstract: 280,853. Hammer, C. Nov. 18, 1926, [Convention date]. Cap - stoppers, bayonet - joint ; stoppers, making.- A metal cap for glass containers comprises a top 2, Figs. 2 and 3, and a depending skirt 5 provided with a crescent - shaped closed or tubular lug 8 formed by pressing the bead inwardly at two peripherally spaced points. The radius of curvature of the inner face of the lug is less than that of the beaded edge 7 of the cap and the lug is less compressed between its ends than at the ends. The cap is formed with corrugations 6 and portions of the bead are offset inwardly to form the lugs 8. The upper or thread engaging surface 12 of the lugs is curved or bevelled in cross-section and may be inclined in the direction of its length to correspond to the inclination of the threads on the container. In making the cap, a hat-shaped blank is disposed on a chuck formed with recesses corresponding to the lugs 8 and, after the flange has been pressed radially inward to form the beaded edge 7, the blank is engaged by a punch 20, Fig. 7, having projecting ears separated by a crescent-shaped portion. The resulting lugs are of crescent-shape and of such dimensions as to pass over the neck of the container. The arc formed is smaller than that of the bead 7 which is adapted to pass over the threads on the container neck. Specification 241,809 is referred to.

IPC: H03F3/36
Filed: 1955-06-07
Abstract: 797,893. Valve amplifying circuits. RANK CINTEL, Ltd., [formerly CINEMA-TELEVISION, Ltd.]. June 6, 1956 [June 7, 1955], No. 16321/55. Class 40 (6). Zero drift in a D.C. amplifier 1 is reduced by comparing the potentials appearing across capacitors 2 and 7 in the input and output circuits of the amplifier respectively, the circuits of the said capacitors being so arranged that the potentials appearing across them are equal when there is no zero drift, and thus deriving an error signal which is applied to the amplifier 1 to reduce the zero drift therein. Additionally the time-constants of the resistance-capacity networks in the input and output circuits are made equal to ensure an identical response in both networks to a given signal. The potentials across capacitors 2 and 7 are applied alternately by means of a vibrating contact 10 to a capacitor 8. If zero drift occurs, an alternating potential is applied to amplifier 11 and phase-sensitive detector 12 the output of which is applied to amplifier 1 in a suitable manner to reduce the drift. The correcting signal may for example be applied to the normally earthed grid of a cathode-coupled stage in the amplifier.

Title: Apparatus for use in character generation
IPC: G09G1/00
Filed: 1974-04-16
Abstract: 1442544 Character generator ROCKWELL INTERNATIONAL CORP 16 April 1974 [11 May 1973 (2)] 16530/74 Heading G4A A character generator, by executing a program of instructions individual to a character to be displayed, establishes, for each successive value of one co-ordinate in a two co-ordinate system, values of the other co-ordinate representing the initial and terminal points of a section of the character along the particular value of the one co-ordinate. The generator may be used in conjunction with a CRT whose beam is alternately unblanked and blanked at successive ones of generated Y coordinate values during its Y scan at each successive X co-ordinate value, the Y values being computed during the preceding scan. The program defines the character in its maximum size, scaling factors being used to display smaller sizes. An exemplary program is shown in Fig. 3B to develop the character of Figs. 3A and 3C. The instructions are taken in sequence, each instruction being started at a cycle determined by a value in the preceding instruction and all instructions being executed in each successive cycle until cancelled (EOLP) or replaced by a later instruction. The allowable instructions include BOLP instructions which establish initial Y values for a pair of outlines, e.g. 1 and 2, Fig. 3C, defining the initial and terminal point of a section of the character. The Y values are stored in increasing value in a circulating store together with an identification of which outline they relate to and are compared with the current Y value of the beam position to control unblanking and blanking of the beam. Slope instructions CM establish a slope for a specified outline by specifying a Y increment (or decrement) which is used to modifiy the current Y value for the next scan, the increments (and decrements) being read from an R.O.M. by coded signals M in the instruction. Change slope instructions CK progressively modify the slope as the current X value increases, each slope being maintained for a number of cycles (X values) determined by values read from an R.O.M. so as to match the outlines traced to a curve more closely. EOLP instructions delete the Y values for specified pairs of outlines and an EC instruction deletes all Y values, terminating the display. The Specification describes the system in some detail, specifying the R.O.M. contents and the way in which they are arranged and used so as to reduce the amount of storage required.

D., 94, Hope Street, Glasgow.-(Naamlooze Vennootschap van Berkel's Patent Constructie Maatschappij ; 2, Volastrat, Rotterdam, Holland) June 11, 1935, No. 16779. [Class 27] The goods storage compartment of a coinfreed vending machine is adapted for the accommodation of both cooling means and heating means, so that the goods can be cooled or heated according to their nature. As shown, articles are disposed along a helical plate a carried on a shaft f having a screw n in engagement with a fixed nut or abutment o. Feathered on the shaft f is a bevel gear k meshing with a gear l on an operating shaft which can be rotated a limited amount bv a handle m after the insertion of a coin. The rotation transmitted to the shaft f is accompanied by a downward axial movement owing to the engagement of the screw n and nut v, the lowermost article on the plate a being swept off by a fixed abutment, and discharged through a shoot u. The helical plate a surrounds a drum b which accommodates the temperature modifying means, e.g. removable electric heating elements or dry ice. Alternatively, heating may be obtained by circulating hot water or steam, and cooling by incorporating a refrigerating apparatus in the machine. Reference has been directed by the Comptroller to Specifications 17732/01 and 192,714, [both in Class 27].
