Title: Improvements in the manufacture of blue water gas from bituminous fuel
IPC: C10J3/00
Filed: 1931-01-27
Abstract: 371,841. Water gas generation. POWER-GAS CORPORATION, Ltd. and RAMBUSH, N. E., Parkfield Works, Stockton-on-Tees. Jan. 27, 1931, No. 2616. [Class 55 (i).] Blue water gas without admixture with distillation gas, and a fuel gas consisting of crude producer gas or " blow " gas with distillation gas are produced in one apparatus from bituminous fuel. During the "blow," air is admitted at the base 4 of the generator 1, and the products pass up through the fuel in the retort 2, the mixed " blow " and distillation gas passing to gas-outlet 6. During the "run," steam is admitted at 4 and reacts with the coke to form blue water gas which leaves the generator through ports 3 without coming into contact with the fuel in the retort. The generator may be down-steamed, the functions of 3, 4 being reversed.

Title: A circuit arrangement for the emergency release of electrical locking devices in railway signalling route setting systems
Inventor: GERLACH OTTO
IPC: B61L19/06
Filed: 1961-01-23
Abstract: 936,011. Route setting. SIEMENS & HALSKE A.G. Jan. 23, 1961, No. 2654/61. Class 105. In an emergency release arrangement for the locking and/or interlocking of route elements in a route setting system, a relay is provided in association with each route element which blocks the locking and/or interlocking reset circuit for that element, controlled by an emergency release device, when the route signal is set to proceed and a route section in advance of the signal is occupied until the signal is manually set to " stop " and the delay time of a time limit relay has expired. Assuming a route set between line d and line b, Fig. 1, setting circuits for the route points W3, W4 and safety points W1, W2 energize relays (not shown) which close contacts W31, W41, Fig. 2, and contacts W33, W35, W43, W45, Fig. 3, and the " proceed " setting relay for signal D closes contacts FD1, Fig. 2, and FD2, Fig. 3. As a result blocking relays AW3, AW4 for route points W3, W4 and AW1, AW2 for safety points W1, W2 are energized and block circuits, Fig. 4 (not shown), extending from an emergency release device to lock and/or interlock reset circuits associated with the points. If the emergency release button for the route is operated, contacts HTD1-HTD3 closed, after a train has entered track section GD and track relay contents GD1  and GD2 have reversed, time delay relay 2b and an emergency release relay Db operate and via contacts Db1 and Zb1 set signal setting relay HD to " stop." Contacts FD1 and FD2 therefore open but the blocking relays are maintained operated by contact Zb3, Fig. 3, until the expiration of the time delay of relay Zb, this delay enabling even the slowest train to clear the points section before the points can be moved.

Patent GB-939265-A (GB)
Title: Measurement and control of constituent chemical potentials
IPC: G01N27/12
Filed: 1960-01-25
Abstract: 939,265. Measuring bridges. LEEDS & NORTHRUP CO. Jan. 25, 1960 [Jan. 30, 1959], No. 2715/60. Class 37. [Also in Groups II and XXXVIII] An A.C. operated resistance bridge 82 (Fig. 2, is adapted for calibrating a measuring resistance 11 for determining the constitution of a furnace atmosphere (see Group XXXVIII). At the commencement of operations, the bridge output at 81 is high, and is interrupted cyclically by a modulating network 79 and amplifier 78 to effect cyclic operation of certain relays associated with the operation of the furnace. As a steady state is approached, the bridge output falls and the cycling rate is reduced. For calibration, relay 112 is operated to shift the energization point of the bridge from the slidewire 101a to the other end of resistor 113, and at the same time to short out the modulating network 79. The bridge output will now be low, and the relay 77 falls off, its c contacts energizing a motor 117 to adjust resistors 114 and 115 until the bridge output has risen sufficiently to operate relay 77. Meanwhile, the resistance of element 11 is altering (by means not shown), and the bridge output rises to a sufficiently high value to close the a and b contacts as well as the c contacts. The motor 117 is now driven in the opposite direction and adjusts resistors 114 and 115 accordingly. At the same time, relay 118 is energized to ensure that the motor 117 can never be driven back in its original direction and to start a time-delay relay 106. Each time the upper winding of the motor is energized, a further relay 122 is simultaneously operated and its contacts stop the relay 106. During the initial part of the calibration operation the bridge output is high and the relay 77 will be pulsed at a relatively high rate so that relay 106 will be switched off again before it has completed its time cycle (e.g. 4 minutes). As calibration proceeds, the pulsing of relay 77 will become slower, and eventually relay 106 will be able to complete its cycle and terminate the calibration operation. The bridge output is also applied across resistors 134 and 135, of which the latter is preset simultaneously with the slide-wire 101a. A motor 133 adjusts resistor 134 for balance and indicates the value of element 11 continuously on a chart 61. The bridge reading is compensated for temperature changes by a slide-wire 126 adjusted from a thermocouple 20. A modified circuit having the same essential features appears in Fig. 4 (not shown). Specifications 939,266 and 939,267 are referred to.

[Class 40 (v)] An oscillator having a step-by-step coarse tuning control, a fine tuning control and a trimming control is provided with means to indicate the tuning error at each step for the purpose of setting the trimming control. The indication of the tuning error is effected by observing the error in the beat frequency produced. The error in the beat frequency may be observed by comparison with another oscillator of low frequency which may be the beat frequency oscillator used for C.W. and may 'have the frequency of 450 K.C. Alternatively, the arrangements may be such that a standard frequency generator produces such frequencies that two different frequencies are produced in a mixer which are mixed to provide the comparison. The trimming control may be arranged to produce a frequency change independent of the setting of the step-by-step control as described in Specification 563,788 and a single operation may set the fine tuning to a predetermined setting and bring into operation the frequency checking means. As applied to a superheterodyne receiver in which the local oscillator is required to be tuned to a frequency differing from the signal by the intermediate frequency, the mixer may be that of the receiver and the intermediate frequency amplifier may be used to select and amplify the beat frequency. The error in the beat frequency may be observed by beating with an oscillator having the correct difference frequency which oscillator may be the beat oscillator for C.W. telegraphy reception.

Abstract: 606,409. Drinking appliances for animals. MARECHAL, G. T. J. Feb. 1, 1946, No. 3235. Convention date, Feb. 7, 1940. [Class 5(ii)] Relates to a cattle drinking trough of the type in which the supply of water is controlled by a valve held closed by a weightactuated part and opened by movement of a pivoted member operable by the animal. According to the invention a weight-loaded part independent of the trough controls the valve and carries or is connected to the pivoted member. A pivoted nose-plate 2 with lateral projections 3 is supported in bearings 12 within a drinking bowl 1 and has two arms 4 extending inwardly and downwardly and carrying adjusting screws 11 bearing against the underside of a weighted part 5. The weighted part 5 rests upon a washer 8 on the nozzle 7 leading from a water supply pipe 26. The part 5 carrying weights in the form of removable bars 9 is free to move vertically between guides 24 and the inner surface 25 of the bowl 1, sound insulating material 14 being arranged between the part 5 and the guides 24 and wall 25. To prevent splashing the underside of the part 5 is provided with a recess 13. Upon depression of the noseplate 2 by an animal the screws 11 lift the weighted part 5 off its seating on the nozzle 7 and water enters the bowl 1. As the water level in the bowl rises the animal ceases to press on the nose-plate and the weighted part 5 sinks back on to the nozzle and cuts off the water supply. In a modification the guides 24 are omitted and the weighted part 5 is formed integral with the nose-plate 2 so that instead of moving vertically it is rocked about the pivots 3. In a second modification the weighted part is pivoted on an axle and is recessed to receive the end of the nose-plate 2. In a third modification the weighted part 5 is arranged in a chamber having a cover with an orifice communicating with the water supply pipe 26 which is placed above. The nozzle 7 passes through the base of the chamber and a control bar passing through the nozzle 7 has its upper threaded end screwed into the underside of the weighted part 5. The lower end of the control bar bears against the inner end of the noseplate 2. A pivoted cover plate 27 may be provided in each form of the invention.
