Title: Improvements in or relating to devices comprising a closed circuit of ferromagnetic material having high retentivity
IPC: F24F3/16
Filed: 1955-04-12
Abstract: 766,037. Electric digital-data-storage apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 12, 1955 [April 15, 1954], No. 10470/55. Class 106 (1). [Also in Group XXXIX] In a non-obliterating read-out arrangement for a store of the saturable ferromagnetic ring type, a pulse is applied to a winding or windings so arranged that in one part of the magnetic material the field due to the flux and the remanent magnetism are in the same direction and in another part they are in opposite directions. In such an arrangement it is found that the part in which the field due to the pulse opposes. the remanent magnetism, returns to its original magnetized state after the pulse terminates. As shown, Fig. 3, a storage element 1 comprises a read-in winding 2 and a read-out winding 3, a pulse being applied to the two oppositely poled coils 4, 5, connected in series when read-out is required. As shown, the field due to coil 4 opposes the remanent magnetism and temporarily changes the direction of magnetism to produce a large change in flux in coil 3. The opposing change due to coil 5 is only small since this portion of the ring remains saturated. In the event of the remanent magnetism being in the opposite direction, the above considerations are reversed and the change of flux in coil 3 takes place in the opposite direction. The output of the coil 3 comprises an integrating circuit the polarity of whose output thus indicates the state of the core. In a modification, Fig. 4 (not shown), there are provided two output coils connected in series opposition, and located respectively near the coils 4, 5 and so arranged that any transformer action between the pairs of coils is cancelled out in the output circuit. In a modification, Fig. 5, the pulsed winding 12 passes through a hole in the toroid so that, say, the field due to the pulse and the remanent magnetism are respectively in the same and opposite directions on the upper and lower sides of the hole. A coil CD surrounding the part above the hole thus receives large or small voltage pulses according to the direction of the remanent magnetism. Alternatively two series-opposed coils may be wound on the parts above and below the hole and the state of the core is then determined by the polarity of the pulse obtained from an integrating circuit connected thereto. It is also found that the same results can be obtained from a single coil wound round. the main body of the core. Fig. 6 illustrates such a coil CD, the winding FH being threaded through a plurality of holes in the toroid to increase the effect. In a storage matrix of such toroids, Fig. 8, storage is registered by simultaneously pulsing horizontal windings h, k, m, and vertical windings e, f, g, and read-out is effected by pulsing the winding 12 threaded through holes in all the toroids, each toroid having its own output winding 13.

Reference has been directed by the Comptroller to Specifications 1,189,545 and 1,013,893.
Patent GB-105646-A (GB)
IPC: C09C1/00
Abstract: 105,646. Wade, H., (Titanium Alloy Manufacturing Co.). May 10, 1916. Pigments consisting of titanium oxide and an insoluble sulphate are obtained by treating a concentrated solution of titanium sulphate for instance of 1.40 specific gravity with a solution of a soluble salt such as a chloride, for instance calcium or barium chloride in equivalent proportions, and digesting (not boiling) the mixture say at 100‹ C. until the titanium oxide has precipitated upon the sulphate; or the mixture may be distilled at 100‹ C. and the residue extracted with water. A product richer in titanium oxide may be obtained by adding a part of the chloride solution first, then filtering, then adding to the solution the remainder of the chloride and finally digesting. The precipitate is finally calcined. The titanium sulphate solution may be obtained by dissolving a titaniferous material such as ilmenite in sulphuric acid, or fusing it with an alkali compound and then dissolving in sulphuric acid; or by dissolving in sulphuric acid for instance in a digester, at 100- 150‹ C. a soft gray form of titanium oxide obtained by fusing titanic oxide with an alkali sulphide (or alkali sulphate and carbon) and, if desired, lixiviating the melt.

Title: Improvements in measuring stretchable tubular fabric
Inventor: MORLEY THOMAS KEVIN
IPC: D06H3/16
Filed: 1957-04-02
Abstract: 891,391. Testing fabrics. HOSIERY & ALLIED TRADES RESEARCH ASSOCIATION. June 30, 1958 [April 2, 1957], No. 10670/57. Class 42 (2). [Also in Group XIX] A portable hand appliance for the measurement testing of tubular fabric, particularly ladies' stockings, has feelers 4, 5 for engaging the interior of the fabric tube at spaced locations, manually operated means for producing relative expansion of the feelers against the tube interior, a spring 28 which yields upon resistance by the fabric to continued expansion of the feelers, means for giving a warning or indication that the yield stage has been reached, and an indicator 7 showing the tube size as measured by the expansion of the feelers. As shown, repeated manual operation of a trigger 6 acts through a pawl 15 and ratchet-wheel 16, gears 12, 11, a pinion 10 and rack 9 to progressively project feeler 5 out of the head 3 of the device, a stop pawl 17 preventing return movement of the feeler. An abutment 7c on feeler 5 moves a finger 7b along the scale 7a of indicator 7. When the fabric has been stretched to a predetermined load, spring 28 yields and a peg 36 on feeler 4 moves to release a trip lever 33 for a lock pawl 30 which locks gear 12 and prevents further movement of feeler 5, thus indicating that the yield stage has been reached. The position of finger 7b indicates the tube girth at this stage. To re-set the feelers, a finger grip 39 is moved along a slot 40; this causes a cam-plate 37 to pivot at 38 and disengage all the pawls 15, 17, 30 so that feeler 5 can be returned to its initial position and the device removed from the fabric. In a modification, movement of feeler 4 when the spring yields is used to switch on first a green warning light and then a red light indicating that the desired load has been applied. In another modification, the device is operated pneumatic. ally. Telescopically extensible feelers, or different length interchangeable feelers, may be used for measuring different parts of a stocking. Since a knitted stocking will stretch widthwise until the normally curved loops are straightened, the device can be used to give an indication of stitch length; alternatively, it can be used to check girth at the panel or foot of a stocking, or for determining the girth of the elastic top when expanded under a given load; the test result may be used for checking the setting of a knitting machine.

April 6, 1935, No. 10742. [Class 78 (i)] The load carriers of a conveyer which is run at uniform speed are movable relatively to the chains in order that they may be lowered into liquid contained in a tank for treatment of the articles conveyed, e.g. for pickling metals, the duration of the treatment being varied by changing the point of lowering of a carrier. In one construction each carrier 4 is pivoted to links 22 which are pivoted to arms 21 keyed to a rotatable shaft 20 carried by bearings in the chains 23. A star wheel 26, Fig. 2, is secured by a sliding feather key to the shaft 20 and provided with a spring-biassed catch 27 which can be engaged with any one of a series of holes 28 in the shaft, the number of these holes corresponding with the number of positions at which a carrier can be lowered. At these positions a fixed rack is arranged to engage the lower teeth of the star wheel. This engagement causes the rotation of the wheel in a clockwise direction, and the carrier descends from the position shown in Fig. 3 to that shown in Fig. 4. Raising of a carrier at the end of the treatment is effected by the engagement of the upper teeth of the wheel with a similar rack. In a modification, each carrier is suspended by cables wound on drums on the shaft 20.

The lens a, Fig. 3, is mounted on a holder supported by a carriage 16 which slides transversely to the face of the grindstone 10 on a guideway 8 fixed to the main supporting-frame. The carriage 16 is traversed by means of a piston 20, sliding in a cylinder 19 rigidly secured to the frame 8 and having cppositely-projecting piston-rods 21 which engage abutments 23, 24 underneath the carriage. Situated immediately beneath the cylinder 19 is a pendent pump case 28 containing a rotary impeller 31, Figs. 5 and 7, driven through worm gearing 41, 42, Fig. 3, from a shaft 43 geared to the main shaft 11 of the grindstone. An eccentric rotary valve 29, Fig. 7, controls the direction of flow of the oil or other circulating fluid employed. As shown in Fig. 7, the impeller 31 is driving fluid from the right-hand ports 36, Fig. 5, into the left-hand ports 36, and is consequently moving the carriage 16 from left to right. The fluid friction also tends to rotate the valve 29, but this is normally prevented by a double stop pawl or escapement 48 carried at the end of an horizontal rock-shaft 47, Figs. 3 and 5. This shaft is rocked to allow a half-turn of the valve 29, and consequent reversal of the carriage traverse, by means of pins 58 carried by levers 55 secured to the carriage 16.
