Abstract: 281,474. Cooper, C, Holmes, F. B. and Holmes &. Co., Ltd., W. C. Nov. 30, 1926. Materials for purifying ; condensing processes. -Coal &c. gas is cooled to produce an aqueous condensate containing ammonia and then subjected to the conjoint action of the condensate and calcium sulphate, carbon dioxide being introduced, if necessary. To increase the content of ammonia or carbon dioxide, the condensate may be treated to expel the whole of the ammonia and carbon dioxide, the vapours being condensed to obtain these constituents with a diminished proportion of water; or the condensate may be cooled further and used in association with calcium sulphate for washing the already cooled gas. The liquor obtained by cooling the gases may be divided into two portions, one being treated to expel ammonia and other separable constituents which are returned to the gas stream and the other used after cooling for washing the cooled gases and then employed with calcium sulphate in treating the cooled washed gas to which the constituents expelled from the first portion have been added. The treatment may be effected in successive chambers fitted with agitators and cooling coils or other temperature controlling means. The gases may be finally washed with sulphuric acid which is preferably only partly neutralized and used to treat the mixture of ammonia liquor and calcium sulphate employed for extracting ammonia from the gases. The acid material is preferably added to the last portion of the treating mixture after the calcium carbonate formed in reaction with the gases has been separated and when fully saturated. The ammonia liquor may be treated either before or after concentration or addition of acid, to remove pyridine, tar acids, or cyano. gen compounds.

Title: Improvements in or relating to methods and apparatus for measurement
IPC: A21C15/04
Filed: 1956-10-05
Abstract: 819,272. Electric correspondence control. ETABLISSEMENTS E. JAEGER. Oct. 5, 1956 [Oct. 7, 1955; Aug. 6, 1956], No. 30500/56. Class 40 (1). Greater accuracy is achieved in measuring a quantity such as speed over a limited range by converting the quantity into a frequency and subtracting from this frequency a standard fixed frequency. A shaft, the speed of which is to be measured, drives a 3-phase alternator 15, Fig. 6, the windings of which are connected to the plates 16 of three diodes. A constant direct voltage is applied to terminal 20. A waveform is thus fed to output conductor 21 only when the rectified voltages are higher than the voltage applied to 20, i.e. when the alternator rotates at a sufficiently high speed. In Fig. 7, a single winding 22 feeds through a high-pass filter 24 frequencies corresponding to shaft speeds exceeding 7500 r.p.m. The third harmonic is added at 25 and filter 26 passes frequencies between two limits corresponding to shaft speeds of 7500 and 8500 r.p.m. A quartz oscillator 27, Fig. 8, and frequency dividers 28-31 provides a reference frequency corresponding to approximately 7200 r.p.m. A three-phase oscillator, Fig. 9, comprises three triodes with plates 32- 34 connected to the grids of subsequent triodes 2# giving an apparent phase shift of - between 3 adjacent triodes. The reference frequency is fed in at 38. The plates feed grids 42-44 of a four-triode differential system, Fig. 10. The grid 45 of the first triode receives the measuring frequency from the circuit of Fig. 5 or Fig. 6. The circuit of Fig. 10 subtracts the reference frequency from the measuring frequency on the heat principle and the plate currents are fed through preamplifiers and main amplifiers to a rotary-field motor 9, Fig. 3, driving a pointer through a magnet 13. The alternator measuring the shaft speed may also supply a low-sensitivity tachometer 70, Fig. 3, indicating shaft speeds 0-8500 r.p.m. The pointer of the high-sensitivity tachometer may be masked until the speed reaches 7500 r.p.m. The measuring magnets 13, 74 of the two tachometers are displaced along the motor axes to avoid magnetic interaction, Figs. 3 and 11. The field closing plates 78, 79 are adjustable as shown in Fig. 12. If the speeds of two shafts 61,61a, e.g. jet engines, are to be measured the reference frequency may be provided from a common source 63 and the speeds indicated on separate instruments 67, 67a.

A horizontal lock chamber B leading to a reactor servicing chamber (not shown) is closable at each end by a door 26, the drawings showing only one end of the chamber, this end being connectible to atmosphere through a tunnel C. The system functions to transfer fuel elements between the servicing chamber and the exterior of the reactor as disclosed in the parent Specification. The door 26 in its closed position, as shown in Fig. 1, and in the left-hand half of Fig. 2 seals against a seating 4 provided at the entrance to the tunnel C, the door being mounted on a frame 50 carried by a rotatable base-plate 24. Jacks 46 move the door rectilinearly with respect to the base-plate to engage or disengage the seating 4. In order to open the passage between the chamber B and tunnel C the baseplate 24 is rotated through 90 degrees by gearing 36, 38, 40, this plate being supported by a thrust bearing 28 and centred on a pivot 34 by bearings 32.

Title: Road traffic signal controllers
IPC: G08G1/08
Filed: 1971-06-30
Abstract: 1400445 Controlling road-traffic signals GEC-ELLIOTT TRAFFIC AUTOMATION Ltd 24 July 1972 [30 June 1971] 30741/71 Heading G4Q [Also in Division H3]  A road-traffic signal controller includes means to extend a signal phase (e.g. the green period), for a period dependent upon traffic density on a route, the means comprising a digital counter 1 which stores a number representative of the traffic density on the route, a digital counter 2 which stores a reference number which increases throughout the extension period, and a comparator 16 which compares the numbers periodically and causes termination of the signal phase when the reference number exceeds the traffic density number. Traffic density is defined as the number of vehicles per unit time. The signal controller provides a minimum green period, an ordinary (or preset) maximum green period and the further, variable maximum, green period. The counter 1 stores a count of the assessed traffic density, during the ordinary and variable maximum green periods. Counter 2 stores the reference count, which increases from a threshold value at the beginning of the variable maximum green period at any one of a number of predetermined time rates selected in accordance with known traffic characteristics for the routes controlled. The greater the traffic density, the longer it takes for the reference count to exceed the traffic density count; however, a limit to the extension, even with infinitely great traffic density, is provided. A single, long pulse derived each time a vehicle passes over an inductive loop is shaped and doubled to provide two short pulses applied to terminal 3 for passage to counter 1. The count is maintained at zero, by an input at terminal 5, in the absence of demand on a conflicting route. In the presence of such demand, the count proceeds but is interrupted periodically for the comparison with the reference count. Following the comparison, counter 1 is caused to operate as a shift register to provide a running average of traffic density. Each signal phase has an associated threshold value below which no green extension, beyond the ordinary maximum, is provided. The appropriate threshold value is injected into counter 2 and pulses are fed to counter 2 at a rate in accordance with a selected characteristic which is associated with each respective phase. The characteristics and threshold values are determined from known traffic characteristics on the routes controlled. The traffic density count is a 5-bit number, while the reference count is a 6-bit number. In making the comparison, therefore, a decision to change or not to change the signalling phase is made on the basis of the most significant unequal digits only. Limitation of the variable maximum green period is provided by disabling gate 4 by gates 19 associated with counter 1 and set to detect twice the threshold value. A circuit, for modifying the pulses from the inductive loops to provide the specified pulse form at terminal 3, is described (Fig. 2, not shown).
