Title: Improvements in or relating to mechanisms for responding to predetermined electricalsignals of morse form
IPC: H04L15/26
Filed: 1946-05-10
Abstract: 621,690. Selectors responsive to code signals. COOPER, A. H. May 10, 1946, No. 14123. [Class 40 (i)] An alarm device responsive only to a particular signal, such as a series of dashes, each of 3¢ to 4¢ seconds duration, separated by spaces of ¢ to 1¢ seconds, comprises a shaft 1 which, in the absence of a signal, oscillates about an initial position under the opposing actions of a spring 4 and a driving ratchet-wheel 2 which co-operates with a power-driven pawl 3 operated several times a second. The shift carries further ratchet-wheels 5, 6 having, respectively, toothed portions 10, 11 corresponding with the maximum lengths of the dashes and spaces of the signal and with which co-operate pawls 7, 8 actuated by an electromagnet 9 energized by the signal, the arrangement being such that when either pawl engages its ratchet-wheel the other is free, whilst in an intermediate position both pawls are free. A correct signal thus causes the pawls 7, 8 alternately to engage their ratchet wheels to allow progressive rotation of the shaft under the action of the driving pawl 3, return of the shaft by the spring 4 being prevented whilst pawls 7, 8 are changing over by a further pawl 17 then engaging one of a number of notches 18 in a holding disc 16'which rotates with the shaft. Release arms 12, 24 adjacent the wheels 5, 6 disengage pawls 7, 8 and allow the shaft to return if the maximum time limit of either a dash or space is exceeded, whilst if the minimum time is not exceeded, the teeth of one or other of the ratchet-wheels are not in a position to be engaged by a pawl when the other pawl disengages, so that the shaft will again return to its initial position. A shutter disc 19 connected to the holding disc 16 through lost motion closes the notches 18 on return movement of the shaft and so prevents pawl 17 from engaging. After a predetermined angle of rotation of the shaft by a correct signal, a striker 25 closes an alarm or like circuit. Switches 14, 15 and 22, 23 operated respectively by relative movement between release arms 24 and wheel 6 and between the holding and shutter discs may be arranged to cause the release of all pawls. The device may be used as a transmitter by moving a pawl 27 into engagement with a ratchet 26 so that the shaft rotates continuously and drives a cam 28 operating keying contacts 29.

Title: Magnetic film memory
IPC: G11C7/00
Filed: 1967-03-30
Abstract: 1,111,709. Magnetic data storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. 30 March, 1967 [4 May, 1966], No. 14460/67. Heading H3B. Creeping in a coupled-film store is reduced by applying a hard-direction bias to the storage elements. Magnetic films 14 are provided on each side of bit - sense lines 12, storage regions being defined by the intersections of lines 12 with word lines 10. The easy axes of the films are transverse to the longitudinal axes of the bit lines 12. It is stated that creeping occurs when intermittent fields having a magnitude up to about 30% of the anisotropy field of the films are applied to a storage region. To avoid creeping, bias field 26 is applied along the hard axis of the films, the field having a magnitude of between 50% and 100% of the anisotropy field. The bias field preferably acts in the same direction as the word field 20, so that the magnitude of the latter required for writing and reading is reduced. Magnetic material may be provided on the sides of the bit lines to completely close the easy-axis flux. Keeper films 24 may be provided for closing the hard-axis flux of each storage element. A keeper film in the form of a single magnetic sheet overlying the storage plane is also referred to. The bias field may be provided by a solenoid or a Helmholtz coil arrangement, or each keeper film 24 may be made of anisotropic high-remanence material with an easy axis transverse to its length. These keeper films are permanently magnetized in the direction of the word field to provide the necessary bias field.

Title: Improvements in apparatus for slicing meat and the like
IPC: A47J47/00
Filed: 1927-06-07
Abstract: 301,937. Davies, J. H., and Scott, E. B. June 7, 1927. Cutting slices in succession.-In apparatus, for slicing pressed meats, of the kind in which the meat is fed towards the open end of a container by a plunger attached to a rotary feed screw, a hand-knife being guided by the open end of the container, means are provided whereby the screw and plunger may be quickly retracted, or entirely removed from the container, without rotating the feed screw. As shown in Fig. 1, the feed screw F engages normally with a nut segment G and the handwheel H is feathered on the screw so as to be slidable, but not rotatable, therein. In operation, the recessed hub of the handwheel engages under a projecting part g<1> of the nut segment and holds the screw in engagement with the threads. The wheel H may have ratchet teeth on its hub to engage a clicking pawl which indicates the extent of feed imparted to the meat. To permit sliding of the screw and the plunger P, the handwheel H is slid back on the screw F out of engagement with the nut segment G, and the screw is lifted out of engagement with the threads. The container C may be of glass and of circular or rectilinear section. It is supported at one end on a cradle D to which it is secured by a band E tightened by a screw e<3>, and at the other end it is held in an annular packing groove in a back plate B which is integral with, or screwed to the base. A hinged lid M may be provided to receive the cut slices, and it may carry a pad to arrest the knife without damage. The container may have internal ribs to prevent the meat from rotating. In a modification, a pivoted spring-controlled member normally keeps the feed screw engaged with the nut segment. The base is shaped as a cradle to embrace the whole of the bottom of the container and the back plate is integral with the base. The back plate may be split along about two-thirds of a diameter to form an elastic socket to grip the container, and, if desired, lugs may be formed on each side of the slit to receive clamping bolts. The plunger may be attached to the screw as shown in Fig. 1, the sleeve m<3> being driven into the plunger after the bolt and washer f<4>, f<5> have been secured to the screw, or, the plunger may have a through central hole, the sleeve m<3> then being dispensed with. According to the first Provisional Specification, a divided nut may be used instead of a nut segment, the upper half being slidably or pivotally carried and being spring controlled.
