Title: Improvements in and relating to hydrokinetic torque transmitting devices
IPC: F16D33/00
Filed: 1941-05-22
Abstract: 549,154. Hydraulic transmission of power ; governors. HEPPNER, F. A. M. May 22, 1941, No. 6584. [Class 69 (ii)] [Also in Group XXVI] A hydrokinetic torque transmitting device of the kind having a substantially toroidal liquid circuit in which work pump and turbine members is constructed with backwardly inclined channels 1 in the pump wheel of such form that the whole twist of the cross section of the channel in its own plane in proceeding from the inlet to the outlet is progressive. The channels are of a substantially constant cross section, which is that of a rectangle with rounded corners or semi-circular ends. The channels extend through 120 degrees in length as indicated in Fig. 2, and are preferably of the interlaced form as described in Specification 538,758 in which two rows of channels are relatively staggered and are located one within the other at their ends nearer the axis and interlace to form a single row at their ends further from the axis. The form of the channels is determined by laying each over the surface of a cone 61, Fig. 1, having its axis lying askew of and not intersecting the axis of the device. When used with a member having streamline reaction blades 8i, 80, Fig. 5, arranged in conjunction with turbine channels 7i, 70, the channels 7i arranged nearer the axis of the device are set at a steeper angle than the channels 70, and the inner reaction blades 8i are set less steeply than the blades 80. In Fig. 6 a torque converter 10 as above is used to drive a vehicle, and the engine 9 is controlled by a governor 13 driven by the converter and acting to control the engine throttle 16 via a lever 15 mounted on a pivot adjustable by a hand control 17 to permit the speed of the engine to be adjusted. A hydraulic governing device may replace the centrifugal one.

Title: Improvements relating to wired radio signalling systems
IPC: H04H20/77
Filed: 1946-03-04
Abstract: 608,991. Distributing music &c. BRITISH THOMSON-HOUSTON CO., Ltd., and MOIR, J. March 4, 1946, No. 6654. Drawings to Specification. [Class 40 (iv)] In a system in which modulated carrier currents are transmitted along two-conductor lines and distributed to subscribers' receivers, the two-conductor branch line constituting the subscriber's connection is joined to the main transmission line through impedance which is high compared with the line impedance, and the capacitance of the branch line is used as at least a part of the capacitance required to effect the tuning of the input circuit of the subscriber's receiver to the carrier frequency to be received. Tuning to different frequencies is effected by varying either the inductance connected across the receiver end of the branch line or the capacitance connected in shunt or series with the branch line or by a combination of both. Additional capacitance may be introduced in parallel with the branch line and its value chosen or varied to render the capacitance of all subscribers' connections substantially equal.

Abstract: 1,072,826. Signal control. SOCIETE TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. " STIN." Feb. 16, 1966 [March 1, 1965], No. 6711/66. Heading B7N. Arrangement for controlling e.g. a signal 30 when the route to which it gives entry has been set up, comprises a circuit simulating the track layout, manually or automatically operated signal switches 531-536 and command receiving circuits 500, 510 associated with signals 30 and 31 respectively. Assume a route from signal 30 to exit GB, the normal positions of points 32, 33 and 35 required for this route is proved by relay contacts 521, 522 and 524 in the positions shown so that operation of signal switch 533 applies a positive voltage via its contact to receiver 500. The receiver includes a relay with a pair of series-connected, opposed windings 501, 502 connected across the D.C. source with a centre tap connected to the switching circuit and a pair of slave relays 505, 506 connected to the switching circuit and to the positive and negative terminals of the source, respectively. The positive voltage applied by the switching circuit unbalances the double-wound relay which picks up closing contacts 503, 504. As a result relay 506 is energized, opening contact 554 to switch off red signal lamps 555 and closing contact 552 to energize yellow lamp 557.

Title: Improvements in or relating to hand trucks for surmounting kerbs and steps
IPC: B62B5/02
Filed: 1922-03-08
Abstract: 185,067. Jones, H., and McGill, J. March 8, 1922. Hand-trucks.-A hand-truck is provided with a 'pair of hinged sectors mounted between the wheels and handles to act as a fulcrum in raising or lowering the truck to or from a higher level. The sectors 4, Fig. 1, are hinged to the side frames of the truck 1, and are connected to a slidable actuating bar 11 by springs 8. The bar 11 projects forwards to form a striker and is held in its forward position by a spring 13. Slotted latches 16 engaged by pins 19 on the bars 11 normally engage pins 20 on the sectors to hold them up. When the striker encounters a curb or step, it is pushed in to release the sectors. The handles 3 are then raised, Fig. 4, to allow the sectors 4 to be swung forwards by the springs 8, to the position shown, the truck then being raised with the sectors acting as fulcra, after which they may be folded up. In descending steps, the actuating bar is pulled back to cause the hinge connections 10 to lie behind the sector hinges, so that the sector will swing clear of the step.

Title: An improved method of and apparatus for controlling steam temperatures in a reheat steam generator
IPC: F22G5/04
Filed: 1955-03-08
Abstract: 793,048. Regulating steam temperature in water-tube boilers. COMBUSTION ENGINEERING, Inc. March 8, 1955 [March 8, 1954], No. 6779/55. Classes 123(2) and 123(3) In a water-tube boiler comprising a steam generating tube lined furnace F fired by corner-mounted, tilting burners B and from which hot gasses flow through a lateral pass H locating a high temperature superheater section S2 and a high temperature reheater section R respectively receiving steam from a low temperature superheater S1 and low temperature reheater RB disposed respectively in parallel downpass V, 22, the superheat and reheat temperatures are held constant over a wide load range without substantial use of desuperheating by simultaneously regulating the two temperatures by varying the amount of heat absorbed by the steam generating section of the boiler and thus making more or less heat available for steam heating, this being accomplished by adjusting the burner tilt by means of a control C1 and adjusting the amount of flue gas withdrawn from the bottom of the downpass and recirculated to the furnace through a duct 20 by means of a control C2 acting on a damper 23, the controls C1, C2 being actuated in response to changes 'in superheat temperature in the final outlet header and, at loads below the maximum when the reheat temperature would otherwise be too low and the superheat temperature too high, holding the temperature constant by exposing supplemental reheater surface to convection heating by opening a damper 30 at the bottom of the pass 22, thus diverting part of the furnace gas flow from the superheater pass V. The damper 30 is adjusted by a control C3 actuated in response to changes in steam temperature in the outlet header of the high temperature reheater section R. In a modification, the low temperature superheater is disposed in the pass 22 and the low temperature reheater in the pass V, the low temperature superheater being brought into action as the boiler load increases to a maximum with corresponding reduction o-f heat input to the reheater. In a further modification the invention is applied to a boiler operating under a double reheat cycle, the first and second stage low temperature reheaters being disposed in damper-controlled downpasses bypassing the low temperature superheater whilst the high temperature sections are both located in pass H or one in pass H and the other in the furnace chamber F.

Classes 37 and 41. An I-N or I-P junction in a germanium body is produced by heating a pellet of lead or lead-germanium alloy in contact with the body and recrystallizing whereby the recrystallized lead then contains impurities removed from the germanium body to leave a substantially intrinsic region. The impurity-containing lead may be removed by washing with chromic acid or electrolytic etching in lead acetate solution. A very small amount of significant impurity may be contained in the pellet to compensate for slight residual N or P-type conductivity which may be present in the substantially intrinsic region. Arsenic and indium are given as examples of impurities. The invention may be applied to a field effect type of transistor having source and drain electrodes provided on a thin intrinsic region.
