Title: Improvements in or relating to cable and the like telegraphy
IPC: H04L5/14
Filed: 1927-02-26
Abstract: 291,157. Smith, W. S., Channon, H. C., and Partridge, N. G. R. Feb. 26, 1927. Artificial lines and balancing networks.-In an artificial line the lumped inductances are made of the same material worked under the same condition as the loading of the line cable, whose resistance, capacity and variation with frequency and current strength are also simulated by the artificial line. In an example the inductance of the first few hundred miles of cable is simulated by toroidal coils whose cores contain magnetic wire or tape equal in weight and cross-section and similar in composition to that used in the required length of cable. For convenience in manufacture the windings may be in two or more separated sections. The toroidal form of the coils eliminates mutual inductance, and the " added resistance " of the artificial line due to eddy currents and hysteresis is equal to that in the cable. The mean flux density in the toroidal core is made equal to that in the cablewinding by winding a number of turns on the former equal to the ration of the mean diameters of toroid and cable, and in order that the flux mav be similarly distributed in the two cases the ratios of inner to outer diameters are made equal. A nest of concentric toroidal coils of different diameters may be provided. Adjustments may be made by connecting a variable resistance in series with the windings, which may be of lower resistance than the cable: by adding an independent winding for controlling the degree of saturation of each core; by adding a series aircore inductance, to reduce the rate of increase of inductance with current; by adding a series iron-core inductance run at high field-strength per ampere, to enhance the rate of increase with current of the " added resistance " due to hysteresis and eddy current: by adding a secondary winding shunted with suitable impedances; or by adding an eddy-current plate in conjunction with an inductance coil. In order to simulate the lealance as well as the capacity of the line, high-leakance paper condensers may be combined in suitable proportion with lowleakance mica condensers, or condensers having the same dielectric as the cable insulation may be employed.

Title: Improvements in the manufacture and production of active silica
IPC: C01B33/154
Filed: 1926-02-26
Abstract: 270,040. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 26, 1926. Colloidal sols.-In the production of silica gel, the silicon compound (silicate solution. solid silicate, silicon chloride or fluoride &c.) is introduced into the decomposing agent (acid or water) in such a manner that a non-alkaline silica sol is obtained containing at least 9 grammes of silica per 100 c.c. of the liquid, the sol being allowed to set, after which the gel is washed, dried and heated in the usual manner. The washing may be effected with slightly alkaline water with or without an addition of oils, colloids, or substances having capillary activity. The oils &c. may also be added to the sol or to the compounds from which it is produced. The danger of the premature setting of the sols may be avoided by effecting the reaction of low temperature, which may have the effect of increasing the adsorbing power of the product. In the examples sodium silicate solution is run into strong hydrochloric acid, with stirring, a sol containing' 12 grs. silica per 100 c.c. being formed, which after setting, is washed and dried at 70-120‹ C. or more and heated at 300-400‹ C. Nitric or sulphuric acid may be employed instead of hydrochloric. Powdered sodium zeolite is introduced gradually into hydrochloric acid, with stirring, at room temperature or preferably at 0‹ C., the subsequent treatment being as described in the first example.

Abstract: 1,216,723. Pipe couplings. ERMETO ROHRVERSCHRAUBUNG G.m.b.H. 6 Feb., 1968, No. 5819/68. Heading F2G. A pipe coupling is of the kind comprising an externally screwthreaded union 6 against which the end of the metal or plastic pipe 1 to be connected abuts and is secured by an internally screwthreaded nut 2 and packing means, wherein the packing means comprises a bracing ring 5, which also abuts the union and is formed with an inclined face, and a sealing ring 4 of plastics material arranged in a recess formed by a plain bore 2<SP>1</SP> of the nut 2 and an inwardly directed collar portion 211 thereof, the arrangement being such that after assembly and tightening of the nut the bracing ring is caused by the pressure exerted through the sealing ring on its tapering surface to urge the pipe into contact with the end face of the union. This is effected by pivoting of the bracing ring about its point of contact with the union, which causes it to deform the pipe slightly, so that on subsequent dismantling the parts 2, 4, 5 cannot be lost. A locking ring 3 is preferably included, both to allow for excessive clearance between the nut and the pipe and also to prevent overtightening of the nut. As shown, the sealing ring 4 is adapted to flow into the first groove of the threading in the nut to further assist sealing. The inclined face on the bracing ring is preferably a 30 degree bevel. It may alternatively be constructed as an ogee.

Abstract: 758,037. Switching systems; systems depending on the use of static transformers. BRITISH THOMSON-HOUSTON CO., Ltd. March 1, 1955 [March 1, 1954], No. 5948/54. Classes 38 (2) and 38 (4). A switching system for controlling the connection of an A.C. load circuit 8 to a supply circuit 6 comprises ferrite cores 20, 21, each carrying a winding 22 or 23, connected respectively across the supply and load circuits and so arranged that there is little or no mutual inductance between the windings. A further winding 24 is common to both cores and is controlled by a switch 25 whereby this winding may either be short-circuited upon itself to effect coupling between the windings 22, 23 and consequential energization of the load circuit, or open-circuited to effect de-energization of the load circuit. A series of intermediate cores, coupled together in cascade and to the cores carrying the input and output windings by switched windings corresponding to the winding 24, may be provided, thereby forming a system in which closure of a number of switches is necessary in order to connect the load circuit to the supply. Fig. 5 shows such a system wherein an input winding 50 on a core 51 may be coupled to any of the output windings 70, 71, 78, 79, 92, 93, 100, 101 by switched windings coupling other cores. For instance, output winding 70 may be energized by closing switches 56, 62, 68 associated with windings 54, 58, 64 for coupling the input and output cores 51, 66 to intermediate cores 52, 60.

IPC: F42C9/02
Filed: 1957-02-23
Abstract: 846,012. Projectile fuzes. FERRANTI Ltd. May 15, 1958 [Feb. 23, 1957], No. 6136/57. Class 9(1). An arming device for a projectile fuze comprises a frame 10 in which is pivoted a shaft 11 arranged transversely of the projectile and, urged to rotate by a spring 30 and carrying stop means controlling the release of a parallel shaft 29 which may operate an electric switch. One end 12 of the shaft 11, which is of reduced diameter, is surrounded by a collar 13 connected to the shaft by a spring 14. Spring 14 stresses the collar 13 to a position in which an arm 16 extending from the collar abuts a stop 16A. A collar 18 rigidly mounted on the shaft 11 is provided on the face adjacent the collar 13 with abutments 19, 20 corresponding with abutments 21, 22 on the adjacent face of collar 13. In the position of rest, the bent-up end 25 of a lever 26 carried by the shaft 29 extends through a slot 27 in the frame 10 and engages in an annular recess 23 in the collar 18, the shaft 11 being immobilized by the spring 14 which holds the abutment 22 of collar 13 against abutment 20 of collar 18. The spring 30, which is weaker than spring 14, is arranged in a housing 33 having teeth 32 which can be adjusted by an element 31 pivoted in the frame 10 to vary the tension of the spring. The shaft 11 carries a wheel 34 connected by a gear train 35 to a flywheel 36. The device is so mounted in a projectile that on firing a weight 15 on the arm 16 turns the collar 13 and so tends to turn the shaft against the drive of its spring 30. This drives the flywheel 36 and so the projectile accelerates the shaft 11 rotates until the end 25 of lever 26 escapes through an opening in the collar 18; the shaft 29 being stressed by a spring 28 rotates until the end 25 of lever 26 reaches the end of the slot 27, when the fuze is armed.

Title: Improvements in or relating to thermally actuated electric circuit control devices
IPC: H01H71/22
Filed: 1942-05-08
Abstract: 557,090. Thermal switches; electrically-released switches. JENKINS, G. M. O. May 8, 1942, No. 6239. [Class 38 (v)] Contacts 7, 8 of a circuit controller are mounted on leaf springs 29, 30 biassed in the same direction, one against the pull of a wire 2 which carries current, and the other against the adjustable pull of a cold wire 27 susceptible to ambien temperature. In the example, an overload electromagnetic cut-out is operated when the current through a load 1 is excessive so that wire 2 elongates and contacts 7, 8 close, thereby energizing winding 9 to pull armature 39 so that rods 46, normally keeping contacts 3, 4 and 5, 6 closed, slip into groove 49 on armature spindle 41 and the load circuit is interrupted. Re-setting is by pressing knob 10. In a modification, the wires 2, 27 are transverse to the spring leaves 29, 30. In a further modification, Fig. 7 (not shown), adapted for automatic re-setting, the leaf spring 30 bears two, separately insulated, contacts at its free end, one on each side of a double contact borne by leaf spring 29, and connected to electromagnets which alternatively close two pairs of contacts, one controlling breaking and the other making of the load circuit. Another example shows the " hot wire controlling a leaf spring which, on moving away from the spring controlled by the " cold wire under overload causes a sliding pin to be tripped to prevent reclosure and to open the load circuit. Re-setting is by hand.

Title: Process for moulding polytetrafluoroethylene
IPC: B29C48/03
Filed: 1955-03-04
Abstract: 782,700. Injection-moulding polytetrafluoroethylene. TUBE TURNS PLASTICS, Inc. March 4, 1955 [April 1, 1954], No. 6462/55. Class 87(2). Process. (1) Granular polytetrafluoroethylene is heated and agitated until it attains a substantially uniform temperature in excess of 580F., but below the temperature at which the polytetrafluoroethylene becomes mouldable. (2) Sufficient pressure is applied to the material to form it into a dense mass. (3) The dense mass is pushed into a mould cavity and fills the cavity, the temperature not being allowed to rise sufficiently to convert the mass into a mouldable state (this " mouldable " temperature being stated to be about 690F.). (4) The mass in the cavity is heated sufficiently to convert it into a mouldable condition, e.g. to 710 or 715F., whilst pressure is maintained thereon to force it to conform to the shape of the cavity. (5) The temperature of the material in the mould is reduced to a level below the " mouldable " temperature, e.g. to 650F., whilst the pressure on the material is reduced and held at the reduced level until the material has set. (6) Finally the pressure is released and the moulded article is removed from the mould cavity. Fig. 1 shows apparatus for doing this, comprising a cylinder 10 in which the material is worked and heated, an injection unit 2 and a mould 1. In the cylinder 10 the material is heated by bands 11 and by frictional heat to, say, 600F., is compacted in the zone 10a, and is pushed by the screw into the injection cylinder 12. From cylinder 12 the compacted material is pushed by piston 14 into the mould cavity C. The mechanical work thus done on the material raises its temperature, but the rate of motion is so controlled that the temperature does not reach the " mouldable " temperature (690F.). (In a modified procedure the temperature may be raised in the cylinder 10 to a level close to the mouldable temperature and held there in the injection cylinder and runners). When the mould is full it is heated to 710 or 715F., the pressure on the piston 14 being maintained at 30,000 or 37,000 p.s.i. When material exudes through mould vents 18 the pressure is released sufficiently to terminate such exudation, and simultaneously the application of heat is reduced or terminated : e.g. the pressure is released to 4,000 p.s.i. and the temperature to 650F. In a modified apparatus, Fig. 2 (not shown) the zone 10a is formed by a restriction in the cylinder 10. In a further modification, Fig. 3, there are two mould cavities 20 and 22, the cavity 22 being initially filled with a viscous fluid substance, e.g. a silicone base oil, which is used to maintain pressure on the incoming material and is expelled from the cavity by the material.
