Title: Improvements in or relating to control apparatus for boilers
IPC: F23C1/00
Filed: 1957-10-02
Abstract: 856,470. Controlling furnace burners. CENTRAL ELECTRICITY GENERATING BOARD, and EDLEY, W. Sept. 5, 1958 [Oct. 2, 1957], No. 30912/57. Class 51 (1). [Also in Group XXIX] Control apparatus for a boiler furnace 1 fired with a primary solid fuel at 2 or by a secondary fuel e.g. oil at burner 3 comprises a first control device 12 e.g. a floating proportional controller with diaphragm operated pilot valves, receiving a signal of the steam pressure e.g. via a master pressure controller 14, a manual or automatic selecting valve 25 and pipe 13, and signals from the input and output of a solid fuel pulverizer 8 via pipes 16, 17 and emitting at 18 a primary fuel supply indicating signal, a second control device 19 receiving a signal of the steam pressure via pipe 20 and the primary fuel supply signal 18 and emitting at 21 a fuel need signal, and a start device 22 operable by a fuel need signal of predetermined value from the second control device for initiating operation of the secondary burner via a control panel 4. With solid fuelling, the signal from 26 acts via 28 on a regulator 7 operating an automatic feeder 6 controlling the feed from the bunker 5 to the pulverizer, while a fan 10 feeds the pulverized fuel to the burner 2. On the failure of the solid fuelling, e.g. by clogging, the signal from 26 is of such a value as to operate a pressure gauge, the indicator 23 of which actuates a switch which brings the secondary burner into operation. When the primary supply is restored, valves 25, 26 are manually operated to recondition the apparatus for automatic burner control, and then act as air pressure reducing valves for lines 13, 21. The apparatus may be electrically or hydraulically operated.

Title: Improvements in Resonance Cells For Optical Pumping Devices
IPC: H01J65/04
Filed: 1966-07-11
Abstract: 1,152,460. Resonance cells. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 11 July, 1966 [22 July, 1965], No. 31121/66. Heading G6P. A resonance cell, for an optical pumping device, is filled with gas at a pressure so as to control the cell resonance frequency and to compensate for temperature effects. Buffer gas is admitted from the tank 5, Fig. 1, into the resonance cell 7 and the cell 6 of the atomic clock 1. When the clock frequency attains a predetermined value, the buffer gas pressure is at the required level in both cells 6 and 7, and the neck 9 is sealed. In a modification, the frequency drift of the clock, caused by pressure charges during the filling process, is amplified by using heptane as the buffer gas in the clock and separating the clock and cell to be filled by a flexible bellows. Heptane has a frequency drift greater than that of the buffer gas in cell 7.

Title: Improvements in and relating to superconductive binary storage devices
IPC: G11C11/44
Filed: 1958-09-30
Abstract: 887,710. Super-conductor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 30, 1958 [Sept. 30, 1957], No. 31161 / 58. Class 40 (9). [Also in Group XIX] A super-conductive storage element of a two or three-dimensional matrix comprises a thin layer 4 of super-conductive lead alloy between two insulating layers 3, 8 of aluminium oxide. The layer 4 is formed with two semicircular holes 5, 6 separated by a cross-bar 7. A superconductive sensing conductor 2 is mounted between the insulating layer 3 and a glass backing 1. The drive conductors 9, 10 and 11 are insulated and are mounted parallel to the crossbar 7 and the sensing conductor. The digits " 1 " and " 0 " are stored as the presence and absence of circulating current in the layer 4. The element is maintained at 4.2‹ K. which is below the critical temperature 7.2‹ K. of the lead alloy. Write 1."-Two coincident current pulses 9', 10', Fig. 4a, in drive conductors 9, 10 are followed by a pulse 11' in conductor 11. The pulses provide a current waveform 14, Fig. 5 (a), which drives the cross-bar 7 resistive when the drive current 14 and the induced current 15 reach the threshold beyond which the resultant magnetic field makes the cross-bar resistive. The current is dissipated as heat and the resistive condition remains when the current falls as the single pulse 11' follows the coincident pair. The temperature relaxation time is such that the cross-bar 7 cools below the critical temperature 7.2 K. to be super-conductive again before pulse 11 ends. The flux linked with the apertures 5, 6 is trapped when the pulse ends leaving a persistent current 16 representing the digit " 1." A pulse 17 induced in the sensing conductor 2 when the cross-bar is first driven resistive, is not used. If the pulses 9', 10', 11' are applied when the digit " 1 " is already stored by a persistent current 16, the resultant current in the cross-bar 7 is insufficient to reach the threshold and the persistent current 16 representing " 1 " remains at the end of the pulse. Read " 1."-Two coincident pulses 9', 10', Fig. 4c, produce a waveform 24, Fig. 5 (b). In view of the persistent current bias 16, the pulse 18 resulting from the reading pulses is insufficient to reach the threshold and there is no output pulse in the sensing winding 2. The absence of an output pulse signifies that " 1 " is stored. Write " 0."-The three pulses 9', 10', 11', Fig. 4b, are coincident and the current induced in the cross-bar 7 is sufficient to drive it resistive even when a " 1 " is already stored as a persistent current 16. The pulse terminates within the relaxation time of 0.3 Ás. and there is no remaining flux to be trapped when the cross-bar cooks again to the critical temperature 7.2‹ K. Read " 0."-The coincident reading pulses 9', 10' are sufficient, in the absence of a circulating current, to drive the cross-bar resistive. An output pulse such as 17 is induced in sensing conductor 2. Specifications 860,280 and 860,281 are referred to.
