Title: Electric car controlling apparatus
IPC: B60L3/10
Filed: 1963-05-07
Abstract: 991,993. Automatic speed control. HITACHI Ltd. May 7,1963 [May 11, 1962], No. 18074/63. Heading G3R. [Also in Divisions H1 and H2] A traction motor 14 is supplied from tapped transformer 10 through rectifier 13, saturable reactors 11, 12 being provided for tap-changing under non-arcing conditions. A wheel-slip preventing circuit senses a voltage proportional to the motor speed and raises the impedance of the saturable reactors as well as adjusting the tapchanger when there is a tendency to wheel-slip. Initially, a reference voltage Vp is supplied to control windings 302, 402 of magnetic amplifiers 30, 40 so that amplifier 30 delivers no output and amplifier 40 causes pilot motor 41 to adjust rheostat 23. The output of magnetic amplifier 22 is reduced to increase the impedance of saturable reactor 12, whilst the output of magnetic amplifier 21 is increased whereby the impedance of saturable reactor 11 is reduced. The tap-changing mechanism under the control of motor 14 closes contact S 1  when the impedance of reactor 12 is high so that no arcing takes place. The impedance of the reactor 12 is then reduced so that the traction motor is started, the next contact S 2  being closed when the impedance of the reactor 11 is at a maximum. The tap-changing operation is repeated to increase the motor terminal voltage, contact S 3  being closed when contact S 1  is opendd, and the operation being terminated when the terminal voltage V f  equals the reference voltage Vp. If the driving wheels start to slip, the voltage V f  exceeds the voltage Vp and the output of amplifier 40 is reversed to reverse the tap-changer. At the same time, the amplifier 30 energizes control widnings 211, 221 of amplifiers 21, 22, so increasing the impedance of reactors 11, 12. The terminal voltage of the traction motor is rapidly reduced to restore the adhesion of the wheels. The saturable reactors 11, 12 may be replaced by reactors of the auto-excited type, or by grid-controlled rectifers.

Title: Improvements in or relating to coating-applying machines
IPC: A43D95/06
Filed: 1935-06-25
Abstract: A coating - applying device comprises a reservoir for coating liquid and a coating applying roll rotatably mounted in and substantially entirely housed in a slot in a roll carrying member, to which slot coating liquid from the reservoir is delivered through a passageway of small cross-section having a delivery end from which the liquid passes to said slot and having, at its other end, a valve, operable by the user of the device, to control passage of the liquid through said passageway.  The device illustrated, for use in applying a colouring liquid to Viennese edges of a heel breast flap F, comprises a reservoir 103 communicating, through a tube 101 and a fine passage 169, with a slot 130 in which the V-grooved applying roll 128 is almost entirely housed, delivery of liquid being controlled by a valve 163 and treadle rod 168.  The roll carrying member 133, formed as a detachable sleeve, has its lower surface inclined to the axis of the roll 128, <PICT:0458769/III/1> <PICT:0458769/III/2> <PICT:0458769/III/3> the surface 134 serving to position the workpiece.

Abstract: 773,259. Soot-blowers. BABCOCK & WILCOX, Ltd. June 24, 1955 [June 25, 1954], No. 18271/55. Class 99(2) In a fluid heat-exchange apparatus having an inner partition wall 24 separating regions 31, 32 subject to hot fluid flow, means are provided for giving access from the exterior of an outer wall 22 at a side of the region 31 remote from the wall 24 to the other region 32, those means including a tube 26, affording a passageway, secured at the inner end thereof to the wall 24 and extending from that wall across the region 31 to an opening in the wall 22. A fluid-tight joint permits relative movement in the direction of the length of the tube between the tube and the wall 22, the outer end of the tube being closeable by removable sealing means. The tube 26 houses, for example, the cleaning fluid supply tube 27 of a soot-blower. The regions 31, 32 may be respectively the open gas pass and the convection heating gas pass of a tubulous vapour generator. As shown, the tube 26 is supported from superheater tubes 28 by spaced tube ties 28a and is slidably engaged in an annular flange 18 within a tubular member 17 rigidly attached to a reinforcing plate 20 of the casing 21 of the generator. A chamber 19 is formed between the member 17 and the tube 26, a lantern ring 14 of H- section and provided with radial holes 36 being disposed between and with pliable packing 13 in the chamber. Within the tube 26 is a cleaning fluid supply tube 27, supporting a nozzle 25 located in the pass 32 and. adjacent the wall 24, which is rotated by drive mechanism 1 connected by flanges 8 to the tube 26. A chamber 15 is formed between the member 17 and the tube 26 and gases are prevented from flowing from the pass 31 into that chamber by air supplied by a forced draught fan through a conduit 2 connected to a pipe line 6. Provided in the wall of the tube 26 are a number of obliquely inclined passages 12, air being supplied through the holes 36 in the ring 14 to those passages to prevent the escape to atmosphere of gases from the pass 32 when the soot-blower drive mechanism is removed.

The aerosol passes into the reservoir and the larger drops are returned to the liquid therein, and the remainder is drawn through a conduit 49 to the main air stream at 13. The plug 42, against which is sealed a sight-glass 31, may be turned slightly to vary the amount of air admitted thereto. Fig. 3 shows a modified plug with liquid and air conduits 46<SP>1</SP>, 48<SP>1</SP> and a replaceable baffle 50.
