Title: Improvements relating to signalling apparatus
Inventor: PUCKLE OWEN STANDIDGE
IPC: H04W88/02
Filed: 1949-02-08
Abstract: 677,836. Party-line systems. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 8, 1950 [Feb. 8, 1949], No. 3393/49. Drawings to Specification. Class 40 (iv). [Also in Group XL (c)] In a system for providing communication between a main receiving and transmitting station and a plurality of subsidiary receiving and transmitting stations, means are provided for preventing one of the subsidiary stations communicating with the main station in the event of the main station already receiving signals from a further subsidiary station. As applied to a radio system (see Group XL(c)), to call the main station the operator at a subsidiary station lifts his telephone handset to energize his transmitter, and announces his call sign. The operator at the main station then energizes his transmitter, the carrier wave being received at each subsidiary station, operating a relay to render each station incapable of transmitting and energizing a warning lamp. The main station operator then transmits a coded signal allotted to the station which has called, which through a selective calling device attached to the receiver energizes the transmitter, connects a loud-speaker, and de-energizes a lamp at the calling station. The operator can then communicate with the main station. The main station operator can call a subsidiary station by first energizing his trans. mitter which energizes a lamp and de-energizes the transmitter at each station, the code signal then being sent out and causing a bell to ring at the selected station. In the case of a land partyline system of telephony or telegraphy a signal of a frequency outside the band used for the transmission of intelligence is used to render the subsidiary stations incapable of transmitting, and instead of de-energizing a transmitter disconnects the microphone from the line. Communication between subsidiary stations may be effected via the main station, in this case the exchange.

Title: Method for the gaseous reduction of metal ores
IPC: C21B13/04
Filed: 1974-01-24
Abstract: 1410464 Reducing metal ore FIERRO ESPONJA SA 24 Jan 1974 [22 Feb 1973] 03407/74 Heading C7D Metal ore (e.g. Fe, Ni, Cu, Sn, Ti, Ba or Ca ore) is reduced in a reducing reactor using gas of composition 15-40% CO, 5-40% CO 2 , 15-50% H 2 , 10-60% CH 4  at 750-900 C the effluent gas being recycled to form a reducing circuit.which is topped up with hydrocarbon gas and maintained at temperature by burning to 800 to 1200C in a combustion chamber supplied with oxygen prior to entering the reducing reactor, a stream of gas is bled from the reducing circuit to a cooling circuit in which ore reduced in a previous cycle and contained in a cooling reactor is cooled. The cooling reactor is then emptied, charged with fresh ore and functionally exchanged with the reducing reactor i.e. reducing gas is fed to the new reducing reactor (the original cooling reactor) and a stream is bled from the new reducing to the new cooling circuit to cool reduced ore contained in the new cooling reactor (the original reducing reactor). A catalyst e.g. sponge Fe, nickel oxide or alumina may be utilized in the combustion chamber. Alternatively the reducing gas may be fed initially to the cooling circuit and a stream bled therefrom to the reducing circuit.

Title: Flow regulating apparatus
IPC: G05D7/03
Filed: 1944-02-28
Abstract: 592,884. Fluid-pressure servomotorcontrol systems. EICHER. F. Feb. 28, 1944, No. 3626. [Class 135] In apparatus in which the flow of a fluid is regulated automatically by a valve in dependence upon some controlling condition such as fluid flow, temperature, pressure or liquid level, and in which the valve is adjusted in dependence upon an impulse transmitter by means of a servomotor, which has throttling means in the path supplying working medium thereto, means are provided for temporarily increasing the cross-sectional area of the path for the working medium for the purpose of operating the valve rapidly when required. As shown, a constant flow is maintained in a pipe 1 supplied by a pump 2 by means of a valve 4 regulated by a servomotor 6 in accordance with the pressure difference across a throttling point 7. This pressure difference acts on a piston 11 which actuates a control valve 12 supplying a control pressure conduit 16, the pressure in which acts on the valve 12 in opposition to the pressure difference acting on the piston 11 so that valve' 12 is automatically returned to its neutral position after a change in the pressure difference. The control pressure in the conduit 16 acts on a further valve 17 controlling the servomotor 6. The valve 17 is operated against a spring 80 and has supply and exhaust conduits 21,19 which are normally restricted by throttling devices 23, 20 respectively. In order to interrupt or re-establish the flow in the pipe 1 rapidly, further valves 24, 22, 32 are provided. The valve 24 has supply and exhaust connections 36, 29 and is raised by a solenoid 27 controlled from a distant point by a switch 8. The latter is normally closed but on being opened as shown, the cylinders 31, 30 of the valves 32, 22 are connected by a conduit 28 with the drain 29. The valve 32 falls immediately placing the servomotor in connection with a drain 35 so that the main valve 4 closes. Due to a throttle 37, the valve 22 carrying the throttle 23 falls slowly. When the switch 8 is closed again the valve 24 is raised placing the pressure supply 36 in connection with the conduit 28 so that the valve 32 is immediately raised to cut off the drain 35 from the servomotor. Due to the restriction 37, however, the valve 22 is not raised immediately and pressure fluid from the supply 36 passes unchecked through conduits 38, 21 and past the valve 17 to raise the servo-, piston 5 quickly and so open the valve 4. Control by the pressure difference across the throttle 7 is now effective again and as the valve 22 has now had time to reach its upper position, the throttle 23 is once more effective. Thermostatically controlled electrical means may be employed where the controlling condition is temperature.

Abstract: 1,163,195. Controlling change-speed gears. FORD MOTOR CO. Ltd. 27 Jan., 1967, No. 4127/67. Heading F2D. A manual shift five-speed gear-box of a motor vehicle has an interlock controlled by a device responsive to gear-box tailshaft speed to prevent downshift from a particular gear to another particular gear above a predetermined tailshaft speed and to allow such a shift below said speed. The five-speed gear and a two-speed axle combine to give the following sequence of overall ratios: (numbers-gear ratios, lettersaxle ratios) 1L, 1H, 2L, 2H, 3L, 3H, 4L, 5L, 4H, 5H. To prevent engine overspeeding, 4H to 3L downshifts in particular are blocked above the predetermined tailshaft speed. In Figs. 3, 4, latches 61, 71 engageable with a selector shaft 80 respectively prevent downshift from a first to a second particular gear above a first predetermined speed, and downshift from a third to a fourth particular gear above a speed. Shaft 80 rotates clockwise to engage said second gear and anticlockwise to engage said fourth gear. Each latch is spring engaged and solenoid retracted. The signal from a pulse generator 30 is related to vehicle speed and is fed via a flipflop circuit (not shown) and smoothing circuit (not shown) to the bases of two switching transistors (not shown) which control the energization of relays 93, 94, respectively, which in turn control energization of the solenoids for the latches 61, 71 respectively. Rheostats between the smoothing circuit and the transistors allow adjustment of the predetermined tailshaft speeds. In Figs. 1, 2 (not shown), a single latch, with a similar but single path control circuit, blocks engagement of the ratio 3L above a predetermined speed.

Title: Improvements relating to cementitious material
Inventor: URMSTON CHARLES WILLIAM BRABAZ
IPC: B28C5/32
Filed: 1964-01-31
Abstract: <PICT:1087812/C1/1> Aerated concrete is produced from a wet mix of aluminium, cementitious material and fine aggregate by a method involving rapid movement of the various particles and sudden changes of the direction of movement; if coarse aggregate is to be employed it is added to the pre-mixed cementitious material and fine aggregate in a second separate mixing step which is terminated immediately the coarse aggregate is sufficiently distributed in the other material. Suitable mixing apparatus comprises adjacent drums 1, 2 containing pump chambers 5, 6 with impellers 7, 8 rotatable at 2000 r.p.m., the drums being fitted with valve systems 9, 10 which allow recycle or discharge of the mix.  In operation, aluminium and water followed by cement and fine aggregate are fed into drum 1 from above, the recycled mix entering tangentially via valve 10 causing a vortex to be set up in which the falling cement particles spin at 400-500 ft./sec. for 15-30 sec. before entering pump chambers 5 and 6 where they are forced at high speed between impeller 7 and the wall; the particles are thus forced rapidly from generally horizontal to generally vertical movement in the drum and pump chamber respectively.  The mix is then discharged to drum 2 where fine aggregate is added and mixed in the same general manner; sand or fly ash may be used and in the latter case the second drum 2 may be dispensed with. A second mixer is then used for the addition of coarse aggregate under heating from steam and hot water.  Alternative apparatus is illustrated in Figs. 2-4 (not shown).  The present mixing technique may be applied to the inventions of Specifications 1,000,875 and 1,040,442.

Abstract: 678,255. Threshing machines. DECHENTREITER, J. Feb. 22, 1951 [Jan. 13, 1951], No. 4315/51. Class 58 In a combined mowing and threshing machine in which the drive of the individual parts is effected from a common shaft, e.g. the shaft 5 of the threshing drum, which in its turn is driven by a motor 3, the drive of the individual aggregates is divided into two groups of which one, namely, that lying in the feeding direction of the cereals before the threshing drum, e.g. the upper and lower band cylinders 43, 44, conveying bands 23, 22, mowing beam 25, windlass 30 and straw discharger 15, is adapted to be disconnected by means of a coupling from the threshing drum and from the group lying beyond it, e.g. elevator 9, scattering blower 11 and press 7. As shown a belt 12 runs from a disc 13 mounted on the shaft 5 over a disc 16 mounted on the shaft 18 of the upper band cylinder to a tension roller 17 which is mounted eccentrically on the crank end of a shaft 33 mounted in the casing 1 and provided with a handle 34. When the handle 34 is turned from the right top end to the left lower end (as seen in Fig. 4 not shown), a cam 37 on the shaft 33 is also turned, and abutting against the brake jaw 38 pivoted at 39 presses the brake 38 against the rim 40 of the disc 16 thus releasing the tension of the belt 12 whereby no transmission of power takes place between the shafts 5 and 18 so that the conveying bands 22, 23, the straw discharger 15, the mowing beam 25 and the windlass 30 are disconnected. When the lever 34 is returned to its position the brake 38 is released whereupon the belt 12 is tensioned so that the disconnected individual aggegates can again be quickly brought into operation.
