Filed: 1939-06-05
Abstract: 529,607. Hydraulic brakes. PRATT, J. H., MANLEY, G. E., and GIRLING, A. H. G. June 5, 1939, No. 16401. [Class 103 (i)] Relates to hydraulic control mechanism comprising a master cylinder incorporating a valve mechanism which permits communication between the liquid reservoir and the master cylinder when the master piston is returned to its initial position after a control operation but which cuts off communication between the reservoir and master cylinder immediately a control movement is initiated. In order that closing of the valve mechanism may not be prevented by dirt &c. in the liquid one or other of the co-operating parts of the valve is formed of a soft and resilient material such as rubber and the movable valve element has a relatively large acting surface; a spring for continually exerting a closing influence on the valve is made insufficiently strong to overcome the influence of atmospheric pressure on the acting face of the valve. In the construction shown in Fig. 1, the closed end of the master cylinder 3 communicates with the reservoir through an axial passage 3a controlled by a soft rubber valve head 5 with a concave acting face 5a, the valve head being contained in a cage 10 against the top of which the valve-closing spring 11 bears. The valve head 5 is carried on a stem 6 with an enlarged head 6a working in an axial hole of the master piston 7, the closing cap of the axial-hole abutting against the head 6a when the piston 7 returns to the out-of-action position as shown and lifting the valve head 5 off its seat. In another embodiment of the invention the open portion of the master cylinder is placed within the reservoir, the controlling valve and its port being at this end of the cylinder and a link and crank arm for actuating the piston being also within the reservoir.

Filed: 1920-06-21
Abstract: 145,478. Parolini, C., and Ferron, G. March 31, 1919, [Convention date]. Kinematograph apparatus. - A camera, which differs from an ordinary kinematograph camera in that it has a speed-multiplying gear and colour screens, is turned on its side, when in use, to produce negative films, Figs. 1 and 2, having pairs of colour records A A', B B' &c. and from such films positive films, Fig. 6, having reduced pairs of images A A<1> &c. in the space normally occupied by a monochrome image, are printed by projection in an apparatus in which the films are fed in perpendicular directions; a divided objective for use in projecting the positive films is also described. A camera for producing films as shown in Fig. 1 has gearing such that the film is fed at twice the normal rate, and a transparent rotating disk, coloured, green over one half and orange over the other half, constitutes the colour screens. For films as in Fig. 2, the gearing trebles the normal rate of feed, and the rotating disk has three equal sectors, one green, another orange, and the third opaque, thus producing a blank or " null image " A<0> between each pair of colour records. The printing-apparatus may, as shown in Fig. 3, comprise toothed drums for feeding the films 1, 2. The drums are driven by Maltese cross mechanisms geared together, and have diameters such that the positive film 2 is fed intermittently one picture space, and the negative film 1 is simultaneously fed two or three picture spaces according to the kind of negative film in use. The exposure aperture for the negative film is equal in area to two of the images thereon. Fig. 7 shows a projector objective comprising lenses 25, 26 which are cut so that the separation of their optical centres may be reduced to the distance between the centres of the images A A<1>, &c. of each pair. The lenses, which may have slightly convergent axes, are carried by plates hinged together, the plates being relatively adjustable by a micrometer screw 29 to enable the images A A' to be registered on the screen. Colour screens are provided in the objective, so that, by substitution of this objective for the usual one, an ordinary projector may be used to project the positive films.

Title: Improvements in or relating to data stores
Inventor: WILLIAMS MICHAEL
IPC: H01F10/32
Filed: 1958-05-28
Abstract: 919,023. Magnetic storage devices. GENERAL ELECTRIC CO. Ltd. May 28, 1959 [May 28, 1958], No. 17015/58. Class 38 (2). [Also in Groups XIX and XXXIX] In a matrix data store in which thin magnetic films with a thickness in the range of 300 to 3000 Angstrom units are associated with column and row conductors, each film has its preferred axis along which it exhibits uniaxial anisotropy and two alternative remanent magnetization states arranged parallel to the column conductors. As shown in Figs. 1 and 2, magnetic thin films 1 of a nickel-iron alloy which may include molybdenum or copper are deposited in rows and columns on a glass base 2. Printed circuit boards 3, 4, 5, 6, 7, 8 carrying copper electrodes 9a, 9b, 10a, 10b, 11a, 11b are arranged on the two sides of the glass base, pairs of electrodes such as 9a, 9b being joined together at one end to provide single turn read-out, row and column windings 9, 10 and 11, respectively. It is stated that two modes of magnetization state reversal by a magnetic field applied along the preferred axis by current in a row conductor are possible. In one mode a magnetic field of sufficient magnitude switches the remanent state by direct rotation. In the alternative mode a magnetic field of lesser value causes a slow switching by the growth of reverse domains. In this arrangement the row current applied is of such value as to be unable to effect switching in either mode by itself. This current passes through a row winding in one or other direction according to the binary value of a signal applied to an associated input circuit 12. During the period when row current is flowing, a current is applied from a control circuit 15 to a selected column conductor, this current being of a value in excess of 0.6 of the current necessary to saturate a film in a direction perpendicular to its preferred axis. The combined effect of the coincident currents in a row and column is to reverse the remanent state of a film (if its existing remanent state permits) by direct rotation. Examples of current values are: row 100 mA. and column 1A. A read-out pulse is induced in the winding 9 which is detected as to polarity by a circuit 17. Non- destructive read-out may also be effected by using a column current of one-half the previous magnitude. In this case no reversal of remanent state occurs, but a flux change occurs temporarily which induces pulses in conductor 9 corresponding to the leading and trailing edges of current in conductor 11. The remanent state is distinguishable by the relative polarities of these pulses. According to the Provisional Specification, gold electrodes may be used, and the films 1 may be coated with a silicon monoxide or magnesium fluoride layer. Specification 919,021 is referred to.

The collector of the second transistor element T7, T8 is connected to the emitter of the third transistor element T3, T4 and to one terminal 2, the collector of the third transistor element T3, T4 is connected to the emitter of the first transistor element T5, T6 and to a second terminal 1 which is connectable to a capacitor C thereby to produce an oscillator circuit, the collector of the first transistor element T5, T6 is connected to the base of the second transistor element T7, T8, a first resistive impedance R1 is connected between the bases of the first and third transistor elements and a second resistive impedance R2 is connected between the base of the first transistor element T5, T6 and the emitter of the second transistor element T7, T8 to which a third terminal 3 is connected. In an equivalent circuit, Fig. 3b, of the lamp flashes circuit shown in Fig. 3a when the capacitor C has charged sufficiently the transistor T10 turns on. This turns on the transistor T11 which lights the lamp L and turns the transistor T9 off. The capacitor C now discharges via T10 until the charge on the capacitor falls below a certain level which causes T10 to turn off. This turns off T11 and the lamp L and turns on T9 so that the capacitor C now recharges and the above cycle is repeated. The transistor circuit can be formed as an integrated circuit for connection to the capacitor C and lamp L.
