Abstract: 759,922. Volt-amperes and volt-amperehours measuring. METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 27, 1954 [Oct. 27, 1953], No. 29683/53. Class 37. An electrical meter for measuring voltamperes or volt-ampere-hours in a three-phase system comprises two voltage windings 1, 2, switching means and a further choke core 3 whereby the windings may be connected to the voltage terminals 9, 10, 11 either as shown in Fig. 2 or in Fig. 3, the meter in the former connection providing a measure of the active component, and in the latter connection a measure of the reactive-component, of the quantity to be measured. In the connection shown in Fig. 3, the currents in the windings 1 and 2 lag 90 degrees on those in the same windings in the connection shown in Fig. 2, while the current windings (not shown) are similarly fed in both arrangements; hence if the arrangement of Fig. 2 measures the active or energy component, that of Fig. 3 will measure the reactive or wattless component, the tapping points c on the inductors 1, 2 and the value of the choke 3 being chosen to give the desired result. Alternatively, the coils may be untapped, resistors being connected in series therewith in the energy position of the switch to provide conect relative energization of the coils for the two positions of the switch. In order to calibrate the instrument to measure reactive voltamperes or volt-ampere-hours it is only necessary to calibrate it against a standard wattmeter or watt-hour meter when arranged in the Fig. 2 connection. Fig. 1 (not shown) illustrates the switching arrangement providing the alternative connections of Figs. 2 and 3.

Abstract: 1377745 Torque converters SRM HYDROMEKANIK AB 21 Dec 1971 [25 June 1971 9 Sept 1971] 29886/71 and 42130/71 Heading F2C In a torque converter of the rotating casing type the pump 402 is disengageable from the casing 2 by a friction clutch 406, 408. The clutch shown is the cone type, but this may be replaced by a multiplate type, which allows controlled slip between the casing and pump. In the embodiment shown the clutch is engaged by passing liquid through passages 50, 52, 54 and 56 and through a valve 432 into the working chamber 410, to leave via passages 48 and 50, the presence of valve 432 causing the pressure on the pump to be greater on the side of the pump away from the chamber 410 and cause the clutch to engage. A further clutch is also shown comprising members 442, 440 and 448 which locks the turbine (attached to disc 442), pump and casing together. In a further embodiment (Fig. 7, not shown) the valve equivalent to valve 432 is designed such that the clutch is only engaged when the turbine is rotating slower than the casing, and in yet another a reverse and a two speed gear are attached to the converter, these being controlled with interconnections to ensure that the clutch beween pump and casing is disengaged before the forward-reverse control can be operated. The control of the clutch is by a pneumatically operated valve in the hydraulic circuit.

[Class 89 (i)] [Also in Groups VII and XXII] A rivet for use in blind riveting comprises a member 10 having a tapped end 11 and a thin walled extension 12 terminating in a shoulder 13. The part 12 is expanded to the same diameter as the end 11 forming a groove 15 and the outer end is further expanded to limit the extent to which the rivet can be inserted. The rivet is set by driving in a pin or mandrel to expand the part 12 to fit the hole in the plates &c. and by action on the tapered part 16 to expand the shoulder 13 beyond the plates. A screw is then inserted further to draw the shoulder 13 against the plates whilst upsetting the end 14 to form a coacting flange. In a modification the shoulder 13 is formed by an external flange 19 and the rivet is contracted to render the external diameter uniform thus forming the internal taper 16.

Title: Production of soda ash
IPC: C01D7/12
Filed: 1962-08-07
Abstract: Soda ash is obtained from crude trona by dissolving the trona, which may be calcined, in water, separating insolubles, evaporating to produce a slurry of sodium carbonate containing crystals, mixing the slurry with hot soda ash to absorb the solution, and calcining the resulting mixture to give soda ash, of which at least a part may be recycled to absorb more solution.

Abstract: 761,993. Induction relays. ENGLISH ELECTRIC CO., Ltd. Nov. 5, 1954 [Nov. 6. 1953], No. 30781/53. Class 38(5) To facilitate adjustment of the characteristics of a time-overcurrent induction relay employing a shaped induction disc (i.e. a non-circular, slotted, or perforated disc) braked by a permanent magnet, the magnet has two different independent adjustments, each of which varies the braking torque. As shown, the shaped disc 1 rotates between a pair of two-pole permanent magnets 30 providing a closed magnetic flux path crossing the disc. The magnets 30 are carried by a structure 25 slidable on a guide 26 and fixed at the desired distance from the disc spindle 2 by a screw 27 co-operating with a slot. The upper magnet 30 is pivoted at 28 on an eccentric screw, thus permitting adjustment of ,the air gap, the magnet being held in adjusted position by screws 29. In an alternative construction (not shown) one of the magnets is adjustable by rotation about an axis parallel to the spindle 2 whereby the registering area between the opposed magnets is varied. In a further construction (not shown) a flux diverter is employed. The disc 1 is driven by an electromagnet 24 against the bias of a spiral spring 8 so that a silver contact cylinder 13 carried by the spindle 2 engages a dome 17 on a contact arm 15.

Abstract: 922,396. Building pneumatic tyres. DUNLOP RUBBER CO. Ltd. Aug. 27, 1959 [Sept. 27, 1958], No. 30930/58. Class 144 (1). A rubber side wall is shaped from a flat band 16 by being expanded on a drum 1 into contact with an annular surface 8 of dished form which is complementary to the contour of the sides of a pre-shaped carcase 17, the side wall being held in contact with the surface 8 by vacuum means during application to the carcase side. As shown, the drum 1 carries an annular inflatable tube 3 to expand two flat bands 6 respectively against frusto-conical surfaces 8 of two shaper rings 4 which locate coaxially one at each end of the drum 1. Each ring 4 has a series of passages extending therethrough from its surface 8 to a vacuum chamber 7 provided on its axially outer face, and the two rings 4 are bridged by a cylindrical shroud 14 to define an annular cavity 15 into which the tube 3 expands to effect shaping of the bands 16. With the bands 16 vacuum held against the surface 8, each ring 4 is located coaxially with the appropriate bead 18 of the shaped tyre carcase 17, Fig. 3, the sides of which are then stitched, by means of rollers 19, to the shaped side wall 16. To ensure that the outer peripheral edge of the shaped band 16 is coaxial with the carcase, an annular knife edge 9 defines the outer edge of the shaping surface 8 to sever excess rubber during the shaping operation.
