Abstract: 679,438. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 18, 1950. [Dec. 30, 1949] No. 30778/50. Class 38 (iii). [Also in Group XXXV] A rectifying system for supplying directcurrent traction motors is energized from a single-phase line 4 through transformer primary winding 5 which is earthed at wheel 2, two interconnected secondary windings 6, 7 being coupled with the winding 5. The winding 7 is tapped and is connected with a phase-shifting circuit comprising inductance 10 and capacitance 11 so that the voltage across points 8, 12 is 90 degrees out-of-phase with the voltage induced in windings 6, 7. Three-phase voltage is obtained from terminals 12, 13, 14, and is applied to series-connected discharge valves 15, 16, of the make-alive type. The leads 17, 18 thus form the respective positive and negative supply-lines for the load consisting of the armatures 19 and series field windings 20 of the traction motors. Resistors 21 are shunted across the field windings so as to by-pass ripplecurrents. In the modification of Fig. 2 a filter system 23, 24, 25 is connected in the primary circuit of the main transformer in order to reduce voltage disturbances in the trolley supply. The windings 6 and 7 are placed on separate transformers having primary windings 26 and 27 respectively. The winding 27 is tapped and has a movable contact 30 connected to winding 26, a second controller contact 32 connecting taps 9 on winding 7 with capacitor 11. When the contact 32 leaves the uppermost of taps 9 it engages bar 34 which is connected to the movable contact 36 of stepping relay 37. A balancing relay 38 has coil 40 subjected to the phase-shifted current derived from winding 7, and coil 39 energized in accordance with the current-output of winding 6. These currents are therefore automatically substantially equalized, after the manuallycontrolled starting period, by means of the relay 37 and the contact 36.

Title: Apparatus for stencil-printing thick fabrics
Inventor: WILFORD ERNEST
IPC: B41F15/08
Filed: 1965-07-21
Abstract: 1,112,978. Stencilling apparatus. BRADFORD DYERS ASSOCIATION Ltd. 18 July, 1966 [21 July, 1965], No. 31064/65. Heading B6C. [Also in Division F2] In apparatus for printing on a thick fabric by the application of free-flowing colouring matter through a stencil to the fabric whilst the fabric is on a perforated support forming the top of a suction box, a valve such as 14, Fig. 4, is provided in the side of the suction box so as to be subject to the suction in the box on one face, i.e. to the left, Fig. 4, and to atmospheric pressure on the other face, i.e. to the right, Fig. 4, and yielding means hold the valve on its seat so that the valve opens when the suction reaches a predetermined value to maintain the suction in the box constant. The yielding means may be a spring, or a piston-and-cylinder subjected to air pressure, and the valve may be a flatplate coacting with an annular seating. As shown, however, the valve 14 is frusto-conical and is connected by a rod 15 and ball joints to a lever member 44. The member 44 has one pivot 52 engaging a forked end of a bracket 51 and connected to a piston 49 of a cylinder 48. A second pivot at the lower end of the member 44 is movable in slots 46 in a bracket 45 and is connected to the piston 42 of a smaller cylinder 41. When a low suction is required in the suction box, high-pressure air is supplied to the right-hand side of the piston 49 so as to maintain the pivot 52 on a leftward position. Air at a predetermined low pressure is supplied to the right-hand side of piston 42. When so set, the valve 14 opens when the suction on the valve 14 plus atmospheric pressure exceeds the closing force exerted by the piston 42. For a higher suction, high-pressure air is supplied to the left-hand side of the piston 42 so that the lower end of the member 44 is moved to its rightward position and the member pivots about that end. Compressed air at a low pressure is supplied to the left-hand side of piston 49 so that opening of the valve 14 takes place against the air pressure exerted on that piston. In another arrangement, Fig. 2 (not shown), a lever corresponding to member 44 is movable about a fixed pivot, and at a part extending below the pivot is connected to two piston rods. Compressed air at a predetermined pressure is supplied to a cylinder associated with one of the piston rods for low vacuum working, and is supplied to both cylinders for a higher vacuum working.

Filed: 1949-12-08
Abstract: 681,274. Thermionic valves; electron beam valves. RADIO CORPORATION OF AMERICA. Dec. 8, 1949 [Dec. 10, 1948], No. 31536/49. Class 39(i) An electrical signal translating system comprises electrode means for producing a beam of electrons along a given curved path, an electron receiving electrode arranged to intercept the beam, and control means for changing the total current of the beam wherein means are provided to cause a change in the proportion of the beam intercepted by the receiving electrode in response to transverse deflection of the beam, the signal to be translated being applied to the control means, and the operating parameters and/or the geometry of the system is arranged to cause an interdependent change in the proportion of the beam intercepted and in the intensity of the intercepted portion as a result of a change in the total beam current. In Fig. 2 the electrons from cathode 24 are controlled by a grid 22 and the beam is reflected from an outer shield electrode 12 so that part of it falls on a dynode 14, the secondary emission of which is collected by anode 16, and part falls on a shield electrode 30; a shield electrode 18 screens the output electrodes from the beam forming electrodes. As the current in the beam is increased, by increasing the potential of the control grid 22, the paths of the electrons change from those shown at A to those shown at B owing to space charge effects; thus the current reaching the dynode 14 is doubly increased since it receives a larger proportion of a beam of increased intensity. A transconductance of 36 mA per volt may be achieved with an output current of 3 mA. In a modification, Fig. 1 (not shown), the screen electrode 30 is omitted. and in a further modification, Fig. 3 (not shown). the dynode is replaced by a non-secondary emitting collector electrode, the anode 16 being omitted and the collector electrode being in the same plane as the cathode. In Fig. 5 electrons from an electron gun are deflected by signals applied to deflection plates 92 so that the beam is variably intercepted by the edge 78<SP>11</SP> of electrode 78. The total current of the beam 90 between electrodes 78 and 82 is thus varied and the space charge effect causes variation in the proportion of the beam intercepted by the edge 78<SP>1</SP> of electrode 78; an output load may be connected to the collector electrode 80. In a modification of this arrangement, Fig. 4 (not shown), the intensity of the beam is controlled by a grid instead of by deflection across an intercepting electrode.
