Title: An electric converter
IPC: H02M5/27
Filed: 1965-07-26
Abstract: 1,108,325. Frequency changing. ALLMNNA SVENSKA ELECTRISKA A.B. 26 July, 1965 [27 July, 1964], No. 31711/65. Heading H2F. An arrangement for converting a single phase alternating voltage to a multiphase alternating voltage of lower frequency comprises a number of branch circuits 2, 3, 4, one for each phase, each branch circuit comprising a centre tapped transformer secondary winding 23 and a pair of controllable rectifier elements 21, 22, connected in bi-phase connection and an inductor 24, the branch circuits being connected as a polygon (i.e. for the three phases shown a triangle-viz. delta connection) and the connection points forming the output terminals. Each circuit operates for a number of high frequency cycles at maximum rectifier operation, followed by a number at minimum rectifier operation and a number under blocking conditions, this sequence being displaced in the three circuits. Thus three-phase voltages are developed at the terminals r, s and t, and since one circuit is always operating under blocking conditions no circulating currents are produced in the delta circuit.

Title: Improvements in or relating to braking control systems, more particularly for motor vehicles
IPC: B60T11/24
Filed: 1958-10-08
Abstract: 846,055. Hydraulic brakes. FRANCAISE DU FERODO S.A. Oct. 8, 1958 [Oct. 8, 1957], No. 32177/58. Addition to 811,812. Class 103 (1). An hydraulic mastercylinder for a brake control system of the kind described and claimed in the parent Specification. is characterized in that the primary sections comprising the conduits 27, 271 connected to chamber 56 of the brake cylinders 58 and the secondary circuit including conduits 37 connected to secondary chambers 57 are permanently isolated one against the other but include fluidtight manometers. Connecting-means which permit the establishment or otherwise between the pressure in the primary chambers 56 in relation of manometric dependence according to the relative values of the pressures in the primary chambers 56 on the one hand and the secondary chambers 57 on the other hand. When for the purpose of effecting braking, the pedal 12 is pressed, the block 11 releases the valve stems 25, 35 and 45, whereby the valves 24, 34 and 44 are closed. The volumes of the primary spaces 21 and 41 thus decrease by equal amounts. The oil is forced into the primary conduits 27 and 271 and at the same time acts in chambers 29 and 291 on the plungers 51 and 51<SP>1</SP> against the action of spring 52, the force of which is preferably selected to be sufficient for plungers 51 and 51<SP>1</SP> to remain in contact with 49 and 49<SP>1</SP>. Upon forward travel, at the moment when frictional surfaces of the brake AV are thus urged into contact by the oil in the primary elements 27 and 27<SP>1</SP>, the greater reaction is developed on the secondary side. The oil is forced back under high-pressure through the conduit 37 towards the brake AR and master cylinder 10. The high-pressure is established in chamber 39 and maintains the plungers 51 and 51<SP>1</SP> all the more in the position of maximum separation, which ensures manometric independence of the primary conduits 27 and 27<SP>1</SP> and permits predominantly secure equilibrium. In continuing to depress the pedal 12, the braking action is accentuated whilst the state of equilibrium is maintained.

Abstract: 957,076. Metal working presses. L. SCHULER A.G. Sept. 8, 1961 [Oct. 29, 1960], No. 32297/61. Heading B3H. A system for monitoring the transfer of workpieces 2, Fig. 2, in a gang or multiple press comprises a relay C, Fig. 3b, which controls the operation of the press ram and whose exciting circuit 7 contains a contact u which is opened periodically in synchronism with the ram operation or the workpiece transfer, said contact being by-passed, when a blank is properly ejected and transferred by a second circuit 8 containing contacts I, II, III, N in series, each controlled by a monitoring unit 5 at a working station of the press, and at least some of the contacts are adapted to be bridged separately by a contact d<SP>1</SP> 4  of a relay which operates wherever the monitoring unit associated with the preceding station indicates the absence of a workpiece during the preceding working stroke. This enables the press to perform some idle strokes without stopping whilst fresh workpieces such as 2<SP>1</SP> are supplied to, or a fresh strip of material is supplied to, a pre-working station. The workpieces are transferred by grippers 4 mounted on rails 3 which move inwardly for gripping the blank and then transfer it to the next station. At each station there is a monitoring device consisting of a detector finger 5 actuating a switch 6. The relays may be operated by impulses derived from a cam-operated or rotary switch driven in synchronism with the press ram, which is operated through a clutch controlled by relay C. The contacts I, II, III, N actuated by the fingers 5, are removable from the circuit 8 by plug and socket connections 9. When any of these contacts are open in the circuit 8 they operate, through a circuit 12, one or more warning indicators L. A bridging circuit 13 with contact Si is used to render the monitoring system inoperative.
