Title: An improved magnetic sound record transcribing apparatus
IPC: G11B25/06
Filed: 1955-10-06
Abstract: 771,104. Magnetic recording and reproducing apparatus. UNIVERSITY OF EDINBURGH, UNIVERSITY COURT OF, and ANTHONY, J. K. F. Oct. 6, 1955, No. 28480/55. Addition to 730,664. Class 40 (2). In a modification of the repeating device set out in claims 3 to 8 of the parent Specification, wherein means are provided for continuously recording signals from a reel of tape to a loop of tape and for continuously reproducing the signals on the loop, switch means control erasing means for the loop after reproduction and are operative to stop, simultaneously, the reel of tape and the erasing from the loop, whereby signals on the loop are repeatedly reproduced until said switch means are operated to re-start the reel of tape, and the erasing means restored to permit further recording from the reel tape on to the loop and reproduction therefrom. In the embodiment described, a reel machine A transmits its signal via its amplifier 2 to recording head R of a loop machine B. A switch 81 coupled to the stop-start mechanism of the reel machine A controls an oscillator 3 for the supply of erase and bias current to erase head E and recording head R, respectively. The signal on the loop is thus continuously reproduced by reproducing head P2 and erased by erasing head E. When machine A is stopped, oscillator 3 becomes disconnected leaving the length of the loop between recording head P2 and erasing head E still with its recording thereon, which is repeatedly reproduced by reproducing head P2.

Abstract: 461,917. Bridges ; floors; beams. WILLIAMS & SONS, Ltd., S., and STENT, D. H. Oct. 15, 1935, Nos. 28492 and 31669. [Classes 20 (i) and 20 (iv)] A bridge, floor, or like structure, comprises pre-cast reinforced-concrete beams a of channel section assembled side by side as shown in Fig. 1, with lateral beads b at their base portions disposed in abutting relation so as to provide longitudinal troughs e between adjacent beams, pre-cast concrete g adapted to cover the channels of the beams, and concrete h cast in situ into the said troughs e, and over the beams, so as to embed reinforcements c which project upwardly from the beams and intertie the pre-cast and cast-in-situ concrete. The projecting reinforcement c passes through the meshes of reinforcement i which is laid above the pre-cast concrete slabs g. Each beam may be bridged at intervals by webs d, and the underface of each beam mav be flat or have bevelled edges y. The beams may be slightly arched to such an extent that when under load the undersurface is not deflected beyond becoming straight. The upper surface of each beam, and of the concrete h, may be curved longitudinally as shown in Fig. 3, and the longitudinal reinforcements l of the beam may project at the ends so as to bond into the bridge abutments. The Provisional Specifications describe also the arrangement of the channel beams in pairs, with their mouths mutually opposed, so that no pre-cast cover slabs are required.

Title: Improvements in or relating to artificial limbs
IPC: A61F2/58
Filed: 1946-09-24
Abstract: 616,942. Artificial limbs. EVANS, J., and PARKWOOD (ARTIFICIAL COMPONENTS), Ltd. Sept. 24, 1946. No. 28549. [Class 81 (ii)] The locking bolt and securing catch of a wrist for an artificial hand, of the kind comprising a base-plate on the hand having a grooved peg which is rotatably engaged by a securing catch on the arm fitting, and a locking bolt on the arm fitting to prevent the hand rotating when set in position, are operated by a single lever. The peg 5 of the hand member 3 is grooved at 7 to co-act with a catch 12, Fig. 5, on the arm fitting to secure them together rotatably. A ball catch consisting of three spring-pressed balls 10 on the arm fitting engaging a number of equidistant holes in the base-plate 1 of the hand 3 gives a frictional adjustment for the rotational setting of the hand. A bolt 18, mounted in the arm fitting parallel to the peg 5 engages one of the holes in the base-plate 1 to lock it in position. The bolt is pressed by a spring 20 into the locking position, and is unlocked by means of a lever 21 protruding through a bayonet slot in the arm fitting and secured in the top of the bolt 18. The inner end 24 of the lever 21 projects beyond the bolt 18, so that rotational movement of the lever 21 in the direction of the arrow A, Fig. 5, causes it to disengage the catch 12 and release the peg 5, thus releasing the hand from the arm fitting. There are, therefore, three positions of the lever 21 in the bayonet slot, the first in which the hand is locked against rotational movement, the second, a neutral position, in which the hand is free to rotate against the ball catch and a third in which the hand is completely released from the arm fitting.

Abstract: 1,016,940. Magnetic storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 13, 1964 [July 16, 1963], No. 28824/64. Heading H3B. Binary information is stored in pairs of magnetic cores such as A and B (Fig. 1).by applying to each core alternating current in an information wire 2 linked oppositely with the two cores and an alternating current and a direct current through a selector wire 1, one or other of the cores (depending whether the information is a " 0 " or a " 1 ") being switched, in steps, from a datum state of (positive) saturation to saturation in the opposite (negative) direction while the other core remains in its datum state. The states of the unselected pairs of cores remain unchanged and the alternating currents are provided by parametric cells connected one (6) to the selector 7 through the mixer 4 and the others to the information wires 2. For read-out of the information in a column of core pairs an alternating current similar in phase and amplitude to that used for writing together with a direct current on the opposite direction to the writing direct current is applied to the appropriate line so that the negatively saturated core is switched in steps to positive (datum) saturation and an A.C. output, the phase of which, in relation to the phase of the interrogating A.C. indicates the information stored, is fed to the appropriate parametric reading cell 8. The amplitude of the reading A.C. may be increased by using an additional column wire carrying extra A.C. A matrix designed for series writing is also described (Figs. 3 and 4, not shown).

Filed: 1920-10-13
Abstract: 174,147. Clayton, W., Nodder, G., Gill, J. F., and Chaviara, J. N. Oct. 13,1920. Extrusion machines.-In apparatus for the continuous manufacture of margarine or other edible fats, the consistency of the product is automatically maintained constant by utilizing the pressure variations in the inlet pipe d to the cooler a and blender b to control the temperature of the cooling medium or the quantity of the cooling medium or of the material under treatment passing through the apparatus, or both. If, owing to excessive solidification, the resistance of the material passing through the cooler and blender increases, the pressure in the pipe d rises and the piston c is moved against an adjustable spring e. The valve g attached to the piston opens successively a number of passages h by which steam or other fluid is supplied to the exterior or the jacket of the blender b, and to various sections of the cooler a. The piston may control a valve &c. to reduce the amount of cooling medium or fat passing into the cooler. The invention may be applied to the apparatus described in Specifications 147,257 and 155,477, [Class 29, Cooling &c.].

Title: Improvements in and relating to the manufacture of light-sensitive gelatino-silver halide photographic layers
Inventor: FOSTER JOHN LESLIE
IPC: G03C1/74
Filed: 1953-10-21
Abstract: 751,746. Photographic plates. KODAK, Ltd. Jan. 21, 1955 [Oct. 21, 1953], No. 29090/53. Addition to 688,980. Classes 98 (1) and 98 (2). The method of the parent Specification in which a gelatino-silver halide emulsion applied as a coating on a support is maintained fluent until the silver halide has sedimented is modified by the feature of setting or setting and drying the emulsion directly after coating, after which it is made fluent again for sedimentation. Such fluidity may be attained by raising the temperature to 40‹ C., after soaking in water if drying has been effected. A humid atmosphere for the sedimentation may later be changed to permit final drying. The modified method is more convenient in commercial production. In an example an X-ray emulsion of 6 per cent gelatin is coated on half-plates at a weight equal to 100 grains silver nitrate per 11 square feet, set, dried and packed, and at a later date the plates are soaked in distilled water for 5 minutes at room temperature and then sedimented at 40‹ C. for 1 hour at 95-100 per cent relative humidity, dried again and washed in water at 40‹ C. to produce ultraviolet sensitization by removal of supernatant gelatin.
