Abstract: 1,200,974. Electric fluid detectors. ENGLISH ELECTRIC CO. Ltd. Jan.22, 1969 [Jan.23, 1968], No.3481/68. Heading G1N. Non-conducting fluid, e.g. water leaks in a cooling system, is detected by a sensing device including a body of porous insulating material 12, e.g. glass sandwiched between two electrodes 10, 11, and a body 8 e.g. a felt pad, containing a conducting substance, e.g. sodium chloride. The device also includes an apertured plastics housing 3, 4. When non-conducting fluid enters the housing it saturates the felt pad 8 and the resultant boine solution is absorbed by the glass body 12 so that the resistance between the electrodes is decreased. An alarm or control function may then be operated. Several of these sensing devices may be connected on parallel across a D.C. source, and the particular device affected may be indicated by including a colouring substance, e.g. potassium permanganate, in the conducting substance. Further, such devices may be used in bridge networks for detecting changes in the conductivity of a fluid at various depths.

Abstract: 703,888. Endless-belt conveyers. DUDLEY, E. R. Feb. 11, 1952, No. 3539/52. Class 78 (1) A machine for arranging cans with their axes in a predetermined direction comprises an endless belt having can gauging and turning means disposed above it and guiding means arranged to allow free passage of cans with their axes transverse to the belt and to direct cans whose axes are in the same direction as the belt towards the gauging and turning means. The cans are delivered to the endless belt 20 of the machine by an endless belt conveyer 10 and are divided into two groups by a V-shaped member 13, Fig. 1. Each group passes devices which separate cans 40 hooked together, upset cans 42 which are on end and rotate cans 41 to arrange them with their axes transverse to the belt. The unhooking device comprises inclined plates 44, 46, Fig. 3, When two hooked cans pass between these plates, one of them will be forced up the plate 46 and rotated to separate them. The corner 48 of the plate 46 is upturned and effects the separation of the cans if this has not occurred already. The separated cans pass beneath a pivoted plate 80, the free end of which has a downwardly turned hook 84. This hook engages any can standing on its end and upsets it to lie on its side. The cans are then directed by a spring-controlled pivoted guide 51 to the turning device 50, Fig. 4. This device comprises an arm 55 which is pivoted at 67, is adjustable in length and has a cam 61, Fig. 6, secured to its free end. The minimum height of the cam is determined by adjusting a stop screw 63 and it is maintained yieldably in this position by a spring 65. A bar 66 having a recess 66a at one end is suspended from a beam 45, the edge 45a of which acts as a gauge. The cans which are transverse to the belt are not acted on by the turning device, but the ends of the others engage the recess 66a and as the belt 20 moves on, these cans are turned to the transverse position. A second turning device is provided to deal with cans which have not been turned completely by the first device. Guides 90 direct the cans into shoots 14, 15 which deliver them to a common shoot 16. In a modification the cans are upset by engaging an arm secured to the beam 45 and extending. diagonally and upwards across their path. In a further modification the cans are acted upon by a series of staggered members 50a, Fig. 11, from each of which is suspended a member 66b having a serrated edge 70.

Title: Improvements in or relating to magnetic storage systems
IPC: G11C11/06
Filed: 1960-10-19
Abstract: 930,680. Magnetic core storage matrices. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 19, 1960 [Oct. 19, 1959], No. 35904/60. Class 40 (9). In a storage matrix cores are switched to maximum remanence in one direction to store the O state and are switched to a remanent state short of maximum remanence in the opposite direction to store the 1 state, read-out being effected non-destructively by the application of first and second pulses of opposite polarity and of an amplitude which does not shift appreciable flux when the cores are in the O state but cycles the cores round a minor hysteresis loop when they are in the 1 state. As shown in Fig. 4 each row of the matrix is pulsed from a source A individual to the row to set the cores to the O state. The 1 state is written into selected cores of a row by a halfwrite pulse on the row wire from sources such as Bx1, Bx2 and half-write pulses on the selected column wires from sources such as By1. Read. out is effected from each row by pulsing the row wire from a source such as C1 with one pulse in the O direction followed by another in the 1 direction. Cores in the 1 state cycle round their minor hystersis loop and induce a voltage in the column wire which is detected over amplifiers such as D1. The cores of a row may be selectively set to their 1 states by applying a full write pulse to the row wire and an inhibit pulse to the column wires of unselected cores. Reference has been directed by the Comptroller to Specification 841,669.

Filed: 1943-03-05
Abstract: 563,256. Severing by fusion. HANCOCK, L. J. March 5, 1943, No. 3650. [Class 83 (iv)] In a flame cutting machine for cutting metal along paths of similar shape, a mechanicallydriven tracer is guided by a template or drawing lying wholly round a cylindrical surface and arranged to rotate so as to bring successive points on its profile into position for co-operation with the tracer. Metal may thus be cut along paths of recurring shapes such as a wave form in a metal section without the necessity of laying out a template or pattern for the entire length of the cut. The machine may be of the stationary type in which the section to be cut is laid on the bed of the machine or may be of the portable type having a carriage 1 with track wheels 3 running on the upturned flanges of the beam 4 to be cut. The track wheels are adjustable on their axles 7 to suit the width of the section and may be grooved or check rollers 6 on shafts 9 may be provided. The carriage has extending arms 12 for a cross rail 13 on which is mounted on rollers a carriage 2 carrying on one side an adjustable cutting burner 18 and on the other side a tracing mechanism 16 comprising an electric motor, speed reduction and variable speed gears and a magnetic tracer roller 19 engaging the profile 21 of a cylindrical template on an axis 22 in a plane containing the axis of the back axle 7. The shaft 22 carries a toothed wheel 24 meshing with a toothed wheel 25 on the back axle. When that part of the edge with which the roller is in contact is parallel with the longitudinal track, the template is rotated and the machine travels longitudinally without transverse movement. At other times when said part is transverse, the tracer roller travels transversely taking with it the burner carriage 2. The template may be replaced by a strip template engaging a pair of rollers on the tracer head or a drawing may be carried by the cylinder engaging a hand-guided mechanicallydriven tracer wheel. To sever the web completely an extension is attached thereto at the finishing end thereof.

Abstract: 1,219,631. Fuel Injection pumps. ROBERT BOSCH G.m.b.H. Jan. 26, 1968 [Jan. 27, 1967], No. 4078/68. Heading F1A. In a fuel injection pump of the rotary distributor type in which a by-pass valve is opened during the stroke of the injection plunger to terminate injection, by a pressure pulse operating in synchronism with the reciprocating plunger, the pressure pulses are derived from the feed pump in conjunction with the rotary distributor. As shown in Fig. 1, during the suction stroke the feed pump 1 supplies fuel through passages 32, 33, 36, chamber 34, the pressure in which is regulated by a valve 43, and passages 41, 40, 23. On the delivery tube the passage 39 is closed and delivery takes place through passages 23, 24 to one of the outlets 3; at the same time the high feed pump pressure passes from a groove 36 through valve 38 to the under side of the valve 5 which is raised until the groove 28 connects the by-pass passages 6a, 6b to terminate injection. On the subsequent suction stroke the valve 5 returns towards its stop 29 under the action of the spring 9, pushing liquid beneath it through the adjustable throttle 10, the feed pump pressure during this period dropping to the set pressure in the suction chamber 34. A further embodiment is described in which the inwardly acting plungers are replaced by outwardly acting plungers (17a). In a further embodiment the invention is applied to a rotating and reciprocating plunger type distributing pump.
