Abstract: 685,416. Transformers and inductors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 13, 1951 [April 8, 1950], No. 5976/51. Class 38 (ii). The insertion, of additional magnetic laminations 37 between the yoke laminations in the central joint areas of a T - shaped three - phase magnetic core structure 31 locally reduces the flux density to minimize the core loss thereat due to the butt joints 46 between the core members and to the flux flowing at an angle to the orientated direction of the material grain. The structure is shown as comprising laminations flatwise bent to form a rectangular loop 32 and a half core loop 41 having respective winding legs 33, 34, 42 split into two sections 39, 40; 43, 44 to facilitate coil assembly. It may alternatively comprise three half-core loops not so split. The structure may be bonded, and the joint faces may be worked to a smooth surface to reduce losses. In a modification each insert 37 may extend right across the central joint areas of both the loop and the half-loop instead of there being a separate piece for each such member. Reference has been directed by the Comptroller to Specifications 657,888 and 677,946.

Title: Burglar and like alarm systems employing thermionic oscillators
IPC: G08B13/26
Filed: 1930-02-22
Abstract: 349,496. Indicating proximity of earth or other bodies. FROM Y , E. M. F., 96, Boulevard Montparnasse, Paris. Feb. 22, 1930, No. 5982. Convention date, Feb. 22, 1929. [Class 37.] A burglar or other alarm system comprises a valve oscillator whose anode-grid coupling L, Lg, C1, C2 is normally balanced so that oscillation does not occur. When the balance is disturbed, e.g. by earth capacity between a metallic object OB and the body of a burglar, oscillations are set up, the mean plate current falls off owing to the gridleak arrangement r, C1, and the relay R opens circuit L, L2, and so releases the alarm-controlling relay Rs. The filament current may be derived either from a separate battery, Fig. 1 (not shown), or through a resistance Rh from the anode-current source S of voltage. This may be connected to the point H as shown or to an intermediate point on the resistance Rh, Fig. 3 (not shown). To prevent false actuation the earth-return circuit A may be separated by a condenser C6 from the source S of current. The circuit L1' L2, connecting the above control-apparatus with the alarm Av may be of the normally closed or normally open type. The alarm Av and relay Rs may be energized by separate sources of current. Several systems as shown in Fig. 4 may be grouped together so that their alarm circuits L1, L2 have a common battery and return wire, Fig. 5 (not shown), and the circuits may be distinguished by annunciators; or a single alarm circuit L1, L2 may be governed by several independent controlling relays R, whose contacts are connected in series, Fig. 6 (not shown) and Fig. 7. The relay Rs may be dispensed with, the normally-flowing current through the bell Av, Fig. 7, serving to hold open the contact m until one of the contacts b is broken by de-energization of a relay R.

Abstract: 885,272. Clutches. ROLLS-ROYCE Ltd. Feb. 12, 1960 [Feb. 23, 1959], No. 6242/59. Class 80 (2). In order to prevent wear and overheating of a friction clutch due to residual friction when disengaged, a synchronized dog clutch is interposed between the friction clutch and a driving shaft and is disengaged upon disengagement of the friction clutch. The friction clutch does not engage until the dog clutch has engaged. A driving shaft 26 is axially slidable and has internal dog teeth 27 engageable with dog teeth 28 provided on an end plate 28<SP>1</SP> of a casing 29 of the friction clutch which has plates 31, 33 splined to the casing and a driven shaft 24. Synchronizing means for the dog clutch comprises a sleeve 78 axially slidable on a flange 79 formed on an enlarged portion 26<SP>1</SP> of the driving shaft 26, the sleeve 78 having helical serrations 81 engaging serrations 82 on the enlarged portion 26<SP>1</SP> and a surface 86 on the sleeve being frictionally engageable with the end plate 28<SP>1</SP>. In operation, low-pressure liquid is permanently supplied to a clearance 53 between coaxial tubes 51, 52, and to engage the clutch high-pressure liquid is supplied to the interior of the tube 52 whence it passes through ports 74, 73, 72 to a chamber 71 to act on a plate 69 fast with the input shaft 26 to move it towards the right. Liquid from chamber 71 leaks through a clearance between sleeves 70, 41 and enters a chamber 85 whence it is centrifuged through ports 84 into a chamber 83 to shift the sleeve 78 to the right to engage the surfaces 86, 87. This effects rotation of the casing 29 and facilitates engagement of the dog teeth 27, 28 which occurs immediately thereafter. Movement of the plate 69 to the right uncovers ports 75 so that high-pressure oil is admitted to a chamber 76 and thence through ports 45 to a chamber 77 to act on a piston 38 a skirt 36 of which acts on a presser member 35 so that the friction clutch engages. To disengage the drive, the interior of tube 52 is opened to exhaust. Low-pressure liquid continues to be supplied through the clearance 53 and through ports 55, 54 to a chamber 56 to retract the piston 38 and so disengages the friction clutch. Low-pressure liquid is also supplied through a passage 68 to a chamber 67 to retract the shaft 26 thus disengaging the dog clutch. Specification 885,271 is referred to.
