Title: Encoded magnetic bubble domains
IPC: G11C19/08
Filed: 1975-05-23
Abstract: 1487863 Magnetic bubble devices INTERNATIONAL BUSINESS MACHINES CORP 23 May 1975 [29 July 1974 25 Oct 1974] 22871/75 Heading H3B Magnetic bubbles having encoded wall configurations are produced by inducing a critical wall velocity (e.g. by propagation or nucleation) is a bubble in a supporting medium and selectively applying an in-plane magnetic field to a magnetic layer exchange-coupled to the bubble supporting medium. Normally generated bubbles have randomly occurring wall rotations. Applying an in-plane field to the exchange coupled layer causes the wall rotation, instead of being continuous in either of the two chiral directions, to produce two discontinuities aligned with the direction of the applied field termed "Bloch lines". Bubbles having no such lines are distinguished from those that do by observation of their deflection in a magnetic field gradient, thereby enabling the different bubble types to represent binary data. The generator of Fig. 2 has a conductor 32 which is pulsed to generate a domain D which has no Bloch lines unless a further conductor 28 is simultaneously pulsed 26 to establish an in-plane field in exchange coupled layer 22. The layer may be ion-implanted, a magnetic garnet or a Ni-Fe alloy and the medium 24 a rare earth garnet on a non-magnetic garnet substrate. The conductor 32 may be straight but with a notch to concentrate the generating field (Fig. 3, not shown). Alternatively, bubbles generated by known means such as lasers may be propagated to a position where they are subjected to a field of 40-50Oe or more which imposes a critical wall velocity at which any previously existing Bloch lines are removed, thereby producing a train of bubbles all of the same, no Bloch line, type. These may then be selectively converted to the two line type by an exchange-coupled layer influenced by an in-plane field. Conductor loops (Figs. 11, 12, not shown) provide the fields as in the device of Fig. 2 or the in-plane field may be produced by permanent magnets. The encoding technique may be applied to the column-accessed free lattice data store of Specification 1,486,250 in which columns of bubbles are generated and encoded as above then pushed into a column position in the lattice at the same time as an existing column is with, drawn for sensing according to bubble deflection (Fig. 13, not shown). In another memory device Fig. 1, encoded bubbles generated at 10 in the same manner as in Fig. 2 are propagated along equal length groovod channels 18 to a converging arrangement 14 where conductors P1-P6 are sequentially pulsed to close the bubble spacing from 4 to 2 diameters for insertion into the lattice L which is defined by conductors 34. At the output side the bubbles are opened up by arrangement 16 for feeding to a magnetic field gradient generated by conductors P13, P14 where the different bubble types deflect to respective paths 40, 42 associated with magnetoresistive sensors 44, 46.

Title: Improvements in or relating to linear-dimension gauges
IPC: G01B13/10
Filed: 1951-10-02
Abstract: 693,806. Linear-diinension gauges. SHEFFIELD CORPORATION. Oct. 2, 1951 [Oct. 5, 1950], No. 22915/51. Class 106 (ii). A linear-dimension gauge head for use with an air gauge comprises a body having an air supply path and a transverse bore in communication therewith, a pair of spaced ball retainers, one at each end of the bore, a ball retained by each ball retainer, the inner side of a ball retainer co-operating with the inner side of its ball to control the flow of air past the ball. A device for gauging the diameter of an internal bore comprises a source of fluid pressure communicating with an axial path 11 in a body 10 through a flow meter and end part 12, the flow being controlled by a plurality of balls 13, 14 held outwardly in contact with the work by the fluid-pressure. The ball 13, preferably of steel or other hard metal, is arranged in a retainer 15 which is a press-fit in a radiallyextending passage 16 and has a passage 19, a ball seat 20 and a plurality of outwardlyextending arcuate arms 21. The inner portions of the arms 21 keep the ball centrally aligned while the outer portions are deflected inwardly at 22 to prevent excessive outward movement of the ball but are sufficiently resilient to allow the ball to be sprung into position during assembly. An identical retainer 18 for the ball 14 is carried in a passage 17 preferably in axial alignment with the passage 16. A plug 24 in a continuation 25 of passage 11 prevents leakage and also serves as a stop for rings 26, 27 which slide in the bores 16, 17 and locate the retainers 15, 18 so that the balls are seated when flush with the outside of the body 10. In use, the diameter of the work will control the distance between the balls and seats 20 which will conjointly control the flow so that the meter will indicate the diameter even though the work is not centralized on the body 10. The fluid escapes along longitudinal slots in the body 10. By varying the size of the spaces 26, 27 the same balls and retainers can be adapted for use in different sized bodies 10.

Title: Improvements in or relating to a method of moulding hollow articles of self-setting materials
IPC: B28B1/50
Filed: 1950-09-19
Abstract: Hollow articles of aerated self-setting material are moulded by positioning a hollow thin-walled, open-ended former in each mould of a series of moulds in turn, placing a non-self-supporting mix prepared by aerating a mix containing cement or like self-setting material and a wetting agent between the outside of the former and the inside of the mould and filling the hollow of the former with loose particulate material, the former being taken out of each mould during or after the placing and filling operations and transferred to and positioned in the next mould while leaving the particulate material in situ at least until the mix has become self-supporting. The former may be of sheet steel or aluminium and designed for easy withdrawal by arranging, e.g. that its vertical faces are parallel to the vertical walls of the mould; and it may have suitable projections to aid its positioning in the mould and a withdrawal handle.  Closed hollow articles, or articles with filled cores, may be moulded by first placing a layer of mix on the bottom of the mould, then placing the former on it and filling the former, then withdrawing the former and then spreading a layer of mix on the material in the mould; or the last step could be carried out by inverting the mould and placing it on a layer of mix already formed.  The core material may be sand, sawdust, powdered chalk, flue dust, stone dust, or material with a high insulation value such as cork dust.

Title: Improvements in or relating to headstocks for lathes
IPC: B23B7/02
Filed: 1932-08-17
Abstract: 406,308. Lathes. BUTTERWORTH, A., BUTTERWORTH, H., and BUTTERWORTH, G., Ainsworth Street, Rochdale. Aug. 17, 1932, No. 23030. [Class 83 (iii).] A lathe headstock has a gear arrangement with automatic selector mechanism adapted to vary the speed of rotation of the work-spindle within a wide range in either the forward or reverse direction and includes cam and lever mechanism permitting a sliding clutch member to engage a continuously rotating clutch body the former being connected to a drum with a cam path engaging the bifurcated end of a clutchoperating lever. The spindle 20, Fig. 1, driven either by belt pulley or selfcontained 'electric motor, is connected to the shaft 32 by pick-off gears 11, 12 and is adapted through a bevel train and clutch to drive this shaft in both forward and reverse directions. A high and low-speed train of gears with pick-off wheels 15, 16 and 13, 14 respectively, brought into operation in turn by movement of the clutch 39, completes the drive to the work-spindle 17. The clutches for speed change and reverse are operated thus:- A stop 42, Fig. 4, on the main cam drum 40 contacts a latch 43 which is displaced against spring pressure with lost motion before subsequently raising a lever 44 and depressing a plunger 49, Fig. 5, thus withdrawing a stop 50 from one half of a clutch member 52 allowing same to be pressed by a spring to engage the continuously rotating part 54 ; subsequent rotation of the part 52 drives the cam drum 55 through about half a revolution thus operating the lever 58 for shifting the change-speed clutch, a cam projection 60 on the part 52 raises the lever 44 to disengage the latch and hence stop the motion of the cam drum 55. The clutch for the reverse is operated in a similar manner by the plunger 64, stop 69, clutch part 71 and cam drum 72 except that a latch 67 and plunger 66 prevent this clutch being operated when the high-speed gear is engaged and only permits reversal during lowspeed drive.

Title: Vehicle-windscreen washers
Inventor: PARKES ERIC BERNARD
IPC: B60S1/50
Filed: 1952-09-15
Abstract: 718,336. Windscreen washers. LUCAS (INDUSTRIES), Ltd., J. Sept. 4, 1953, [Sept. 15, 1952.] No. 23092/52. Class 138 (1). In a vehicle windscreen washer of the type comprising a pump, the suction stroke of which is effected by hand or power means and the delivery stroke by a spring, a nozzle adapted to direct a small jet of water on to the windscreen, and means for supporting the nozzle on the vehicle body at a position in front of the windscreen, means are provided for effecting oscillation of the jet to cause it to sweep over an adequate area of the windscreen. Washing liquid in a bottle g is caused to flow through a pipe p and flexible pipe s to a nozzle d, pivotally mounted on the vehicle engine bonnet b, by means of a diaphragm pump. The diaphragm k is caused to effect a suction stroke by means of a rod m reciprocated by a flexible cable o operated by hand or mechanical means, and to effect a delivery stroke by means of a spring n. Known valves r, q, are interposed in the liquid circuit. Cam-like notches on the rod co-operate with a roller u on a stirrup t connected by a flexible cable e to the pivoted nozzle d. When the pump is actuated oscillatory motion is transmitted to the nozzle against the action of a spring f, and the liquid jet v sweeps upwardly and downwardly on to the windscreen a. In another embodiment, the nozzle is fixed relative to the bonnet and a throttling valve is interposed in the pipe s, the valve being oscillated by the cable e to cause fluctuations in the velocity of the liquid supplied to the nozzle and consequent deviations in the direction of the jet v. In a further embodiment having a fixed nozzle the cable e is dispensed with and the cam-like notches co-operate with a spring pawl so that the diaphragm moves in jerks and thus causes the jet to issue at a fluctuating rate. A piston pump may be used in lieu of that shown, and oscillation of the jet may be produced by other means co-ordinated with the pump action.

Title: Improvements in or relating to picture analysis and recording devices
IPC: H04N3/36
Filed: 1951-10-08
Abstract: 705,953. Television. RADIO-INDUSTRIE SOC. ANON. Oct. 8, 1951 [Oct. 14, 1950; Nov. 18, 1950], No. 23401/51. Class 40 (3) In a system for the recording of television images upon or for the generation of television signals from kinema film, there are provided means for deriving a correcting signal from the frame synchronizing pulses and further means employing the correcting signal to compensate for flicker occurring at the picture repetition frequency due to non-uniform illumination of the film gate. In an arrangement to which the invention is applied wherein television signals are generated by the scanning of kinema film, light rays from a scanning raster formed upon the screen 2 pass through two separate optical paths comprising prisms 4 and 5 and the lens 6 so that, were the shutter 15 removed, a pair of images of the scanning raster would be formed one above the other upon the film 3 in the film gate 7. The shutter 15 exposes the upper and lower halves of the gate alternately in synchronism with the scanning of odd and even frames and the film 3 passes continuously through the gate at such a rate that interlaced scanning of the film results. Light passing through the film is focused upon a photo-electric cell 10 which consequently develops a signal which is then passed to suitable utilization circuits. It is found in such a system, or in a similar system for recording images derived from received television signals upon film, that a flicker effect occurs due to non-uniform illumination of the film gate. In order to compensate for this a correcting voltage at one half the frame-recurrence frequency is obtained by applying the framesynchronizing pulses to an Eccles-Jordan circuit and shaping the output square-waves therefrom by means of one or more stages of integrating circuits. The correcting voltage may be applied to a control electrode of the cathode-ray tube on to one or more stages of the circuits conveying the television signals to or from the apparatus. In the case of a transmitter circuit, as illustrated, the correcting may alternatively be applied to the photo-cell 10, particularly when this incorporates a cascade-type electron multiplier.
