Title: Phase shifting apparatus
IPC: H02M5/27
Filed: 1973-10-19
Abstract: 1480899 Single to polyphase conversion; frequency conversion; phase shifting DEFENCE SECRETARY OF STATE FOR 21 Oct 1974 [19 Oct 1973] 48909/73 Heading H2F A phase shifting circuit, e.g. for use in a single to polyphase converter, comprises a singlephase bridge of four arms each containing bidirectional switching means such as thyristors Da1 ... Dd2 having input terminals for connection to a single-phase source 1, connected across one diagonal and output terminals AB across which a phase-shifted voltage of the same or lower frequency is obtained. The single phase source may serve as one phase of the polyphase output, the phase shifted voltage across AB forms a further phase, further bridges being included, if required, to provide further phases, e.g. for a motor. The thyristors may be replaced by triacs or by transistors, each across a diagonal of a diode bridge or by valves or reed switches. The thyristors Da1, Da2, Db1, Db2 are turned on at the beginning to of a half cycle so that the output AB follows the input until capacitor C1 has charged sufficiently to break down unijunction transistor TR1 which provides a pulse on xy which triggers a monostable circuit (Fig. 7, not shown) which triggers a commutating thyristor (not shown) so as to discharge a capacitor through the primary of a transformer, secondary windings T1 ... T4 of which turn off the conducting thyristors. At the same time a 1-2 kHz multivibrator (Fig. 7, not shown) is turned on so as to pulse the other thyristors Dc1 ... Dd2 at time (t 0 +t1). This action reverses the effective connections between source 1 and output terminals AB so as to give a rapid change in polarity of output. The monostable circuit is arranged to be timed out by the next zero crossing so that it causes the conduction of the thyristors to be once more transposed, restoring the connections between source 1 and terminals AB. A further thyristor TH is triggered by the unijunction transistor TR1 and prevents further triggering of TR1 once it has triggered in any half cycle. The voltage (Fig. 2) across AB is thus seen to be effectively phase shifted with respect to that of the source 1 by an amount which is a function of the variable resistor VR1. Fig. 8 (not shown) depicts a filter in the form of a parallel resonant circuit in parallel with two series resonant circuits and used for harmonic suppression. In Fig. 9 (not shown) each arm of the bridge is formed by a diode bridge having a transistor across one of its diagonals, the transistors being triggered by a master timing unit via respective bi-stable circuits. Frequency changing.-The switching devices in the arms of the bridge may be triggered so that the output frequency is effectively less than that of the input and may be varied during the starting period of an induction motor to maximize its output torque.

Abstract: 1,033,607. Automatic adjusters for friction devices. WAGNER ELECTRIC CORPORATION. Dec. 17, 1963 [June 5, 1963], No. 49718/63. Heading F2E. An automatic wear-compensating adjuster for a friction device comprises a pivoted member having a follower arm and a driving arm and which is spring biased whereby the follower arm engages a smooth face of a rotatable adjusting member which moves with a friction member of the friction device, while the driving arm engages teeth or undulations on the adjusting member, so that, on energization of the friction device, the pivoted member in following movement of the adjusting member rotates about its pivot to cause the driving arm to slip a tooth or undulation, and upon subsequent de-energization of the friction device the spring biasing causes the pivoted member to rotate in the opposite rotation so that the driving arm rotates the adjusting member which, e.g. through a screw-and-nut mechanism, adjusts the friction member. As shown applied to an internal shoe drum brake which has a pair of shoes 2, 2a engageable with a drum 4 by supply of fluid, e.g. by a master cylinder, to a wheel cylinder 10, a pair of independently operating members 34, 34a are pivoted by studs 40, 40a to the cylinder, spring washers 41, 41a allowing movement of each member out of its plane to permit a driving pawl 43 on a driving arm 42 of each member to slip a tooth 30 of a rotatable adjusting member 26, if during brake application wear of the lining 3 exceeds a predetermined amount. The member 34 is caused to pivot, in accordance with movement of piston 22 together with a screw-and-nut adjuster assembly 27, 32, by a follower arm 44 which engages the back of the adjusting member 26, the latter being integral with part 27 of the adjuster assembly. A compression spring 47 acts on both members 34, 34a to maintain their follower arms 44, 44a in such engagement. On release of the brake the piston 22 and assembly 27, 32 retract, whereby member 34 pivots back and, if the driving arm 42 slipped a tooth 30 of member 26, it now rotates the latter causing relative rotation of the screw-and-nut assembly 27, 32 to advance the retracted position of the shoe 3. The same applies to the operation of member 34a, adjuster assembly 27a, 32a and shoe 3a. Manual adjustment is also provided for by apertures 48, 48a in the backing plate 8, normally plugged to keep out dirt. An aperture 14 in the backing plate locates the cylinder 10. In a modification, Fig. 5, each pivoted member 102 has an integrally formed leaf spring 111 abutting a lug on the cylinder 10 for urging a follower arm 109 into engagement with the back of member 26 to control a driving arm 107.

Abstract: 1478164 Dissolving gas in liquid flow to controlled concentration GEORGE KENT Ltd 20 Nov 1975 [22 Nov 1974] 50789/74 Heading B1C In a method of and apparatus for dissolving a gas in a flow of liquid to provide a solution of predetermined concentration the flow is divided, in proportions which are independent of the quantity of the total flow, between first and second flow paths and the substance dissolved in the flow in one of those paths to provide a saturated solution which is then recombined with the other flow. In apparatus for providing a controlled concentration of oxygen in a flow of water the total flow passes through an annular space 99 between sleeves 5, 7 before being divided (by valve 117, Fig. 6 not shown) in proportions of about 600:1 the minor flow passing in laminar manner over an elongate coiled tube 137 of oxygen-permeable material and through capillary tube 65 before combining with the main branch flow. The latter passes through a variable orifice device provided by glass ball 93 in an upwardly widening passage 83, the purpose of which is to ensure a linear relation between the flow rate and pressure drop of the main branch flow (which is turbulent) and thus to ensure that the proportions in which the total flow is divided remain constant despite changing flow rate. The ends 139 of the tubing 137 are either open to atmosphere or connected at one end to an aspirator to ensure flow of air therethrough, the length of tubing 137 being adequate to ensure saturation of the minor branch flow with oxygen. The decrease in solubility of oxygen in water with temperature increase would tend to make the apparatus inaccurate with temperature variations but this is largely counterbalanced for the range of 10‹C-40‹C by the different effects on the turbulent and laminar branch flows of temperature-linked changes in viscosity of water. The apparatus may be used for calibrating meters for monitoring dissolved oxygen levels.
