Title: Improvements in or relating to electrical interlocking control systems for railway signals and points
IPC: B61L19/06
Filed: 1953-10-26
Abstract: 758,528. Railway signals and points interlocking. SIEMENS & HALSKE AKT.-GES. Oct. 26, 1953 [Oct. 25, 1952], No. 29600/53. Drawings to Specification. Classes 104 (1) and 105. In a control system for railway signals and points having all-electric interlocking with interlocking and locking relays and with points changeable under direct manual control or under the control of route-setting devices, different kinds of currents and impulses are employed for changing over different kinds of devices, for signalling between a relay room and a control panel and for differentiating between through routes and shunting routes. Different types of impulses may actuate through the same conductors route relays, e.g. three position polarized relays which control setting control relays and interlocking relays of points to be travelled over and when necessary as in setting up a through route the locking relays of these points, and the setting control relays, and also the interlocking relays and locking relays of the safety points. Distinctive current impulse, may be employed for back-signalling the positions or conditions of the operated devices. The actuation and locking of safety points are signalled to the associated route points and the locking of this route points is only effected after the reception of the impulse signals indicating such locking of the safety points. Release of a set route is effected by a particular type of current impulse transmitted by key actuation at the control office or in dependence on the track relays to release the locking of the route points and of the safety points. In a practical embodiment described pulses of positive polarity are employed for setting shunting routes and pulses of negative polarity for through routes, utilizing three-position-polarized route relays so that only the appropriate contacts operate in response to the particular current. Both positive and negative pulses are transmitted along the same conductors between the route relays in the relay room and the control panel.

Title: Improvements in or relating to propellers for helicopterous aircrafts
IPC: B64C27/54
Filed: 1925-11-26
Abstract: 263,599. Mellander, J. Nov. 26, 1925. Screw propellers. -Propellers for sustaining and propelling helicopters comprise a number of vanes the longitudinal axes of which may be varied in inclination to the propeller axis and also the axes of opposite vanes are inclinable in parallel relation. The variation in inclination is effected by tilting the rings carrying the vanes. Automatic control by a pendulum is also employed. The vanes a are pivotally connected at the centre of pressure b by wires b c, b d to a ring capable of angular movement at the ball joint e on the hollow shaft f. The vanes are also connected with rings g secured to the hollow shaft, and a ring h secured to a member which can be tilted about the pivot i relative to the shaft, either under hand control or automatically by the pendulum m. The pivoting of the blades at b leaves the vanes free to alter the inclination of their longitudinal axes, and consequently the angle of incidence, cyclically during each revolution. To propel the craft in addition to sustaining it, the ring h its inclined. Springs o are used in the pendulum control and act to increase the natural change in inclination and effect a more speedy control. Oscillations of the pendulum are damped by a plane n.

Abstract: 866,503. Variable -speed epicyclic gear. PRESTON, M. Sept. 2, 1959 [Oct. 8, 1958], No. 29930/59. Class 80 (2). A variable-speed transmission, particularly for a hoist or winch, comprises an hydraulic transmission unit including an impeller 5 driven from the driving shaft 1 and a turbine rotor or runner 7, a three-element epicyclic differential gear unit of which a first element (planet carrier 12) is directly coupled to the turbine rotor and a second element (annulus 16) is directly coupled to the driven shaft 3, clutch means being arranged between the driving shaft 1, 2 and the third gear element (sun wheel 15), and a selectively operable brake 11 being engageable with the first gear element. In the arrangement shown the clutch means between shaft 1 and sun wheel 15 comprises a free-wheel clutch 14 and a disc friction clutch 17, while a locking-up disc clutch 18 is provided between planet carrier 12 and annulus 16, a brake 23 is provided on the clutch element integral with sun wheel 15, and a one-way brake 9 is mounted between the turbine rotor 7 and the reaction member 4. For maximum lowering speed at any given engine speed brake 11 is applied to bring the converter output shaft 8 to rest, and if the load is light, clutch 17 is also applied to lock sun gear 15 to driving shaft extension 2. Increased hoisting speed with maximum driving torque is obtained by engaging locking-up clutch 18 and clutch 17 with brakes 11, 23 released, so that the whole gear unit is solid with output shaft 3, one-way clutch 14 permitting shaft 2 to overrun sun gear 15. If clutches 17, 18 are both engaged direct drive is obtained between shafts 1 and 3. With brakes 11, 23 and clutches 17, 18 all disengaged the load may be inched up or down by varying the engine speed. In other arrangements, Figs. 2 and 3 (not shown), the gear unit comprises double planet pinions meshing with two sun pinions, and in a further embodiment, Fig. 4 (not shown), a second differential gear unit is added to give faster hoisting and lowering speeds. An hydraulic coupling with suitable torque and slip characteristics may be used instead of the converter.

IPC: G06F3/023
Filed: 1964-07-29
Abstract: 1,066,953. Digital electric computers. BœROMASCHINENWERK SOMMERDA. VEB. July 29, 1964, No. 30088/64. Heading G4A. In a decimal calculating machine in which arithmetical operations and input are effected by the same control means an input operation is inhibited, if a calculation is being effected until the termination of a cycle of the calculation, and the commencement of a calculation is inhibited until any input operation which may be taking place has been completed. The machine described is a keyboard input machine operating with 12-digit binary coded decimal words in series by digit and in parallel by bit, operands being stored in registers (MR, MD, AC, Fig. 1, not shown), which together with an input buffer register (E) constitute a 4-plane ferrite core memory (SP). The machine is capable of effecting addition, subtraction and multiplication. The columns of the matrix memory (SP) are scanned under the control of a counter (Z) having 12 operative states, during which an output Z = 1 is produced, and a zero state when an output Z = 0 is produced. To enter a decimal digit into the calculator, the appropriate key, Fig. 2, is depressed, a 4-bit coded form of the digit being produced on leads T1-T4 by a recoder U. To prevent incorrect operation due to contact bounce, a monostable circuit UV2 temporarily inhibits a gate K5 which when the circuit UV2 has reset and also when the scanning counter (Z) is in its zero state, indicating the completion of a cycle of (say) a multiplication operation, is opened to gate the input digit to an auxiliary register E1-E4. A second monostable circuit UV1 is now triggered to block the gate K5 thereby preventing double entry of an input digit. The input digit is transferred from the register E1-E4 to the buffer register (E) in the memory (SP) under the control of a bi-stable circuit UE, the register (E) being scanned, read out, and rewritten with a one-digit shift to permit the new digit to be entered in the least-significant position. The interrupted calculating operation is resumed after the completion of the single cycle of the counter (Z) required to effect the input of a digit. Similarly, if an input operation is taking place when an arithmetic calculation is required to be initiated, the commencement of the calculation is inhibited until the input has been effected, by means of a gate (K9, Fig. 3, not shown) controlled by the bi-stable circuit UE.

Abstract: 1 : 4-Diamino-2-aryloxy-3-sulphoanthraquinones are prepared by heating 1 : 4-diamino-2 : 3-dichloranthraquinones under atmospheric pressure with a phenol and a sulphite of a strong, preferably inorganic, base in the presence of water.  In examples 1 : 4-diamino-2 : 3-dichloranthraquinone is boiled with phenol and aqueous sodium sulphite to give 1 : 4-diamino-2-phenoxy-3-sulphoanthraquinone; this product is saponified to the corresponding 2-oxy derivative by warming with dilute soda and it dyes wool from a faintly acid bath in blue-violet shades.  The sodium sulphite may be replaced by the methylamine salt of sulphurous acid, and homologues and substitution products of phenol may replace the latter; thus when m-cresol is used 1 : 4-diamino-2-cresoxy-3-sulphoanthraquinone which dyes wool violet-blue shades is obtained.  The dyestuffs produced from halogenphenols also yield violet dyeings on wool.

Title: Method and apparatus for control of a boiling water nuclear reactor responsive to steam demand
IPC: G21D3/12
Filed: 1962-08-07
Abstract: 939,995. Nuclear power plant. UNITED STATES ATOMIC ENERGY COMMISSION. Aug. 7, 1962 [Aug. 14, 1961], No. 30164/62. Class 39 (4). A boiling water reactor turbine combination comprises a nuclear reactor in which the fuel elements are contained in coolant tubes provided with ignition nozzles at their lower ends and surrounded by water which is in communication with the nozzles ; a multistage turbine with its speed controlled by a governor actuated throttle valve; a condenser for condensing exhaust steam from the turbine; a pump for returning the condensed water to the reactor by way of the nozzles; and a steam supply line to the pump from an intermediate stage of the turbine so that the speed of the pump is responsive to changes of steam pressure at the chosen intermediate stage of the turbine. In Fig. 4, steam from the reactor 9 passes to a turbine 106 and condenser 112, and the condensed water is returned to the reactor by a pump 120. The pump 120 is operated by steam exhausted from the first stage of turbine 106, the adjustment of the steam supply being by a manually operated valve 132. If the supply of water to pump 120 from condenser 112 is insufficient, a pressure signal from gauge 128 opens valve 126 and allows some of the water surrounding the coolant tubes of the reactor to pass through line 122 to the pump. When the load on the turbine 106 increases, the throttle valve 116 is opened by governor 115 so increasing the steam pressure; this increased pressure is passed on to pump 120 so there is an increased flow of water to the reactor which increases its reactivity since the steam void fraction is decreased. A decrease in the power demand of the turbine has the reverse effect so the system is self-controlling. Specifications 840,789 and 886,874 are referred to.
