Patent GB-1536103-A (GB)
Title: Data storage system
IPC: G11C7/10
Filed: 1977-03-29
Abstract: 1536103 Data storage system NCR CORP 29 March 1977 [29 April 1976] 13106/77 Heading G4A A random access store is connected to an output buffer which stores a word from the store and supplies the word to an output respectively in response to input and output clock signals from a clock generator which initiates the output clock signal before termination of the input clock signal. A check device checks the word in buffer for errors at the termination of the output clock signal.  The clock generator may be a counter driven by the clock of an associated processor, the clock of the store output bus, or a clock internal to the store. The store is such that on average data becomes available at a time 30 following initiation of an access at 25, with a variation between time 32 and normally 34 or abnormally even later. The buffer is clocked for input by signal # and for output by signal MGE as shown, the signals terminating together after time 34. Termination of the signals enables a gate receiving the output of a parity check circuit, an error signal from the gate generating a further output clock MGE at the next clock pulse rather than a complete new access cycle. The arrangement allows the store to provide an output at any time during output clock MGE and checks for errors at the end of that signal.

Title: Improvements relating to haulage transmission gearing for coal and like cutting machines
IPC: E21C29/10
Filed: 1929-04-27
Abstract: 329,482. Anderson, Boyes, & Co., Ltd., and Shield, J. B. April 27, 1929. Coal-cutting machines.-The haulage drum or sprocket of a coal-cutting or like machine is driven from the motor of the machine through change-speed gearing and worm gearing, the change speed gearing including two friction clutches and two positive clutches operable so as to provide four forward and four reverse cutting speeds and two forward and two reverse flitting speeds for the drum &c. In Fig. 1, the gearing is shown out of correct alignment for clearness, pinion D actually meshing with pinions E, Y and pinion W being adapted to mesh with pinion X. Integral pinions A, W, are slidable on the motor shaft 6 which drives the pinion D either through pinions W, X, or reversely through pinions A, B, C; pinions C, X, are integral. For cutting, the pinion D drives through pinion E, two-speed gearing F, G, or B', C<1> controlled by a dog clutch 4, gears H, J, K, L, friction plate clutch 1, and two-speed gearing M, N, or Z, A<1>, controlled by a dog-clutch 3, to a worm O. For flitting, the pinion D drives through pinion Y, friction plate clutch 2 and the two-speed gearing M, N, or Z, A<1> to the worm O. From the worm O, the drive passes through worm wheel P, gears Q, R, clutch 7, Fig. 2, gears S, T and a gear U engaging an internal gear in the haulage drum V. In a modification, the pinions A, W, are rotatable independently on the shaft 6 and are simultaneously slidable so as to bring dog clutch elements thereon alternately into mesh with similar elements on the shaft 6. The Provisional Specification describes transmission gearing in which the change-speed gearing between the motor and the clutch 1 is replaced by a train of reduction gearing and in which the reversing mechanism is provided between the clutch 3 and the worm O.

Title: Improvements in or relating to means for obviating interferences and disturbances inwireless telegraphy and telephony
IPC: G02F1/07
Filed: 1926-05-25
Abstract: 252,409. Telefunken Ges. fiir Drahtlose Telegraphie. May 23, 1925, [Convention date]. Optical and photographic recorders. - Interference in wireless signalling is obviated by means of a differential receiving system in which the incoming oscillations are passed through two slightly detuned transfer circuits u1, u2 to rectifiers R1, R2 so arranged that the output from each acts on light controlling means consisting of one or more condenser arrangements K1, k2 which under the influence of an electrostatic field react, substantially without inertia, upon the brightness of the transmitted light. The transfer circuits u1, u2 preferably possess like time constants. As shown, the light rays after passing through a polarizer PI pass through the dielectrics N of two Kerr cells K1, K2 and an analyzer P2, and affect a recording surface such as a moving photographic film B. The optical system may be so arranged that the directions of the electric field at the Kerr cells are at an angle of 90‹ to each other, as shown, or cells with different dielectrics may be used, the one positive and the other negative, and the cancellation effect be obtained in the optical apparatus. In a modification, a single Kerr cell is employed acted upon by the outputs of the two rectifiers in opposition.

Title: Yarn winding machine
IPC: B65H54/28
Filed: 1961-04-13
Abstract: 934,836. Yarn winding machines. LEESONA CORPORATION. April 13, 1961 [April 25, 1960], No. 13308/61. Class 120 (2). A winding machine having a traversing rod 26, Fig. 1, for moving yarn guides 7 relatively to yarn packages P, includes a speed responsive means 160, Fig. 5, which, when the frequency of oscillation of the traversing rod 26 exceeds a predetermined limit, automatically causes a buffer spring assembly 120 to move from an inactive position, Fig. 7, to an active position, Fig. 9, where it assists the traversing rod 26 to decelerate, stop, and accelerate again, at the ends of its stroke. As shown, a motor M, Fig. 1, rotates a cam 11 and causes cam followers slidable on fixed shafts 22 to reciprocate a pair of bell-crank levers 20 pivoted at 17 on the cam followers. One end 23 of each bell-crank lever is pivoted to the traversing bar 26 to cause it to reciprocate, the length of the stroke being adjusted by varying the inclination of a slotted bar 25 in which the end 19 of each bell-crank lever moves. The motor M also turns a governor shaft 144, Fig. 5, rigidly secured to a cup 150 containing four balls 160 separated from each other by walls 163 depending from a cover 162 for the cup. When the shaft exceeds a predetermined speed the balls 160 move up the walls of the cup to such an extent that the cover 162 is raised to a position in which levers 175 associated therewith cause two buffer assemblies 120, Fig. 7, one on each side of the machine, to move from an inoperative position, Fig. 7, down into an operative position, Fig. 9. The traversing rod 26 has an extension on which are mounted two abutments 56, 58 associated with two pivoted arms 50, 52, Figs. 7 and 9. As the rod 26 moves to the left the abutment 56 eventually strikes the pivoted arm 50 to rock it anticlockwise and when the rod 26 moves to the right the abutment 58 eventually strikes the pivoted arm 52 to rock it clockwise. If the buffer assemblies 120 are in their inoperative position, Fig. 7, the ends 102, 110 of each buffer assembly extends into depressions 64, 66 in the pivoted arms 50, 52 and the movements of these arms are not affected by the buffer assemblies. When the buffer assemblies 120 are in their operative position, Fig. 9, they cause the pivoted arms 50, 52 to be spring biased against motion to assist the rod 26 to decelerate at the ends of its stroke and impart initial acceleration thereto in the opposite direction.

Patent GB-761278-A (GB)
Title: Improved method of collecting micro-organisms growing on a solid matrix
IPC: C12N1/02
Filed: 1954-05-10
Abstract: Micro-organisms growing on a solid matrix may be collected by subjecting the culture to sonic oscillations in such manner that the parts of the micro-organisms projecting from the surface of the matrix are removed therefrom without admixture of the constituents of the matrix.  A liquid layer, e.g. water, is preferably applied to the matrix prior to subjecting the culture to the sonic oscillations, thus producing a dispersion.  A surface-active agent may be added to the water layer to increase the degree of dispersion obtained.  The preferred frequency range is from 20,000 to 30,000 cycles/second. The process is applicable to cultures of Penicillium chrysogenum, Penicillium notatum, Penicillium olivaceum, Aspergillus niger, Rhizopus nigricans, Streptomyces griseus, Bacterium coli, Bacterium subtilis and Bacterium mesentericus.  In an example a culture of Penicillium chrysogentum on an agar-agar sheet is coated with water and subjected to oscillations of frequency 22,000 c/s in a magnetostriction apparatus, to give a dark-green suspension.
