Title: Magnetic Data Storage Apparatus
Inventor: TSUI FRANK
IPC: G11C17/12
Filed: 1968-10-30
Abstract: 1,190,181. Magnetic storage apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 30 Oct., 1968 [18 Nov., 1967], No. 51367/68. Heading H3B. Magnetic storage apparatus comprises at least two sets of co-ordinate conductors electrically insulated from each other and sandwiched between a ferrite layer and a layer of ferrite strips and ceramic strips laid side by side. A ferrite layer 11 has layers of X, Y drive conductors, inhibit conductors 17 and sense conductors 18 disposed thereon as shown in Fig. 2 electrically insulated from one another. A top layer 14 composed of ferrite strips 15 and ceramic strips 16 is then postioned over the ferrite layer 11 and the arrangement compressed and sintered to form a uniform block. The X, Y drive conductors are arranged so that they extend parallel to each other below the ferrite strips 15 to form a storage element having a flux path 20 when energized, and extend orthogonally below the ceramic strips 16, the latter ensuring an annular flux around the conductors. The stray fields extending from the storage elements in the direction of the lines, are reduced by the distance between the column conductors 13 being made to exceed the thickness of the ferrite layer 11 and/or strips 15. In addition the inductance of the driver lines 12, 13, 17 are reduced by these lines being no longer surrounded over their full length by ferrite material. The bottom layer 11 may also be composed of ferrite and ceramic strips so that the storage elements of one line are magnetically insulated from the storage elements of another line. Two storage planes may be united with their top layers 14 facing each other to form a block, Figs. 5, 6 (not shown). In the embodiment of Fig. 7 (not shown) the X, Y drive conductors are straight and arranged orthogonally with the ceramic and ferrite strips of the upper layer 14 extending diagonally. The ferrite strips are arranged so that each of them covers the overlapping of the conductors disposed along a diagonal, Fig. 8 and Fig. 9 (not shown) shows how the invention may be applied to a matrix of transfluxor storage elements. The sandwiching layers are composed of ceramic strips 29 and ferrite strips 30 and the strip conductor network consists of two X conductors 31, 32 per row and two Y conductors 33, 34 per column. The conductors of these pairs have different widths and are spaced in relation to each other. Column conductor 35 serves as a sense line.

Filed: 1974-11-27
Abstract: 1495281 Magnetic core stores R ALKAN & CIE 27 Nov 1974 [14 Dec 1973] 51486/74 Heading H3B [Also in Division G4] Each stage of a counter 3 is associated with a magnetic core memory t whose state is charged by way of windings R1, R2 to follow that of the counter stage. Upon restoration of power to point P after a failure a capacitor Cl charges and after a short delay triggers a thyristor Th1; this triggers a monostable Ml which applies a resetting pulse at R to the counter. After a further delay 5 a pulse is applied at S to the winding e 2  of the memory. If the core was in its set state it is reset and a pulse detected by winding e 3  triggers a second monostable M2 which after the resetting pulse R ends sets the respective stage of the counter.

Supply of low pressure hydraulic fluid to the smaller bore chamber 4 of an intensifier cylinder 1 containing a stepped piston 2 actuated by compressed air in cylinder chamber 3 is effected through a supply line 6 containing a supply and return valve (not shown), a throttle valve 7, an annular chamber 10, a plurality of radial bores 11 leading to a further annular chamber 12 from which extend a first set of spaced bores 13 having their axes skew with respect to the longitudinal axis of chamber 4 and inclined towards discharge orifice 9 of chamber 4 so as to provide tangential inlets to chamber 4 and a second set of spaced bores 14 the axes of which are also inclined to the outlet 9 and which inter-sect the axis of chamber 4. Supply is also effected through branch lines 15 of radial bores 11 to the larger diameter end of chamber 4; any excess being drained through ports 16. Assuming piston 2 to be in its retracted position fluid leaving the skew bores 13 produces a vortex stream in chamber 14 which displaces air from the chamber wall and fluid leaving bores 14 drives out the air. To retract piston 2 from the position shown, hydraulic fluid in power cylinders 18 to which line 6 is connected to return whereon piston 22 and a crosshead 23 carrying a cocking mechanism 17 is urged forward by compressed air in a chamber 5 open to cylinder chamber 3, until when a pin 29 abuts the rear face of piston 2 cams 32 latch in a piston recess 33. Cylinders 18 are then repressurized and pistons 22, 2 retracted thereby repressurizing the air in chambers 3, 5 and when pin 29 abuts end wall 25 of cylinder 1 the cams 32 are retracted and piston 2 is urged forward by air pressure in chamber 3 to perform the hydraulic fluid intensification in chamber 4.

Filed: 1971-10-29
Abstract: 1363079 Aerials MARCONI CO Ltd 29 Oct 1971 [30 Oct 1970] 51625/70 Heading H4A The elements A1 to An of an aerial array are fed through quantized variable phase-shift means whereby the axis of the polar radiation diagram may be set in a desired direction. The limited number of phase steps available with quantization leads to accentuation of grating lobes, and in order to reduce this effect time varying additional small phase shifts, each not exceeding one half of one of said quantized phase steps randomly distributed across the array, are superimposed. The direction of the radiation diagram is consequently caused to move with respect to the desired direction. As described, each aerial element is fed with pulses of radio frequency from a radar unit R through four phase shifters. Thus, the element A1 is fed through the phase shifters 1P1, 2P1, 3P1, 4P1. The phase shifters 1P1, 2P1, 3P1 are controllable through a selector B1 by a computer C to introduce respective phase-shifts of 0 or #, 0 or #/2, 0 or #/4, as may be required for steering the beam. The phase-shifter 4P1 is controlled by a random or pseudo-random number generator NG to produce the aforesaid small additional phase shift. The generator NG may be controlled by the radar unit R so that there is one random number per pulse repetition period. There may also be provided in the feed to each aerial element a fixed phase shift, said fixed phase shifts being randomly distributed across the array.

A device for indicating the position of the axis of a shaft relative to an axis in a machine tool about which the shaft is to rotate comprises angularly spaced slide members 12, 13 radially disposed with respect to the shaft and resiliently urged towards the axis of rotation in the machine tool on which the axes of the slide members intersect, each slide member carrying a feeler member 17 which is engageable with the cylindrical surface of the shaft at angularly spaced points, at least one of the feelers being pivotable on its slide member about an axis parallel to that of the shaft. The feeler members each have an extension arm 21 with opposed electrical contacts 22, 23 which are respectively co-operable with contacts 24, 25 on the slide. In operation the displacement of the shaft from the desired axis of rotation effects the pivoting of the feeler members which produces engagement between respective contacts which are arranged to light indicator lamps and hence indicate the direction of displacement of the shaft from the axis of rotation. The slide members are positioned one 45 degrees above and the other 45 degrees below the horizontal plane passing through the rotational axis. Alternative type of slide members are described with reference to Figs. 2 and 3 (not shown), in which the members take the form of spring-loaded plungers carrying feeler members by rollers and which are interconnected by levers which engage electrical contacts to indicate displacement between the axes.
