Filed: 1968-12-04
Abstract: 1,207,036. Reactors. BABCOCK & WILCOX Ltd. 4 Dec., 1968, No. 57583/68. Heading G6C.  The wall 1, and floor 2, of the concrete pressure vessel of a water-cooled nuclear reactor are thermally insulated by cells 6 filled with U- shaped, glazed porcelain bodies. The wall cells are formed of channel-form plates 5, welded together and to the lining plates 3. The floor cells are built from bent plates 21 welded together and to the lining plate. Apertures 7, 23, 24 and 25 are provided to permit water to fill the cells. At the end of reactor operation, water is withdrawn from the pressure vessel and flows from the cells as the water level falls. The siphon tubes 9 empty the lower regions of the cells. The sealing lining is cooled by the tubes 4.

Title: Automatic frequency control of oscillator
IPC: B06B1/02
Filed: 1967-12-27
Abstract: 1,210,393. Automatic frequency control. OHIO STATE UNIVERSITY. 27 Dec., 1967 [16 Jan., 1967], No. 58673/67. Heading H3A. In a power generator comprising an oscillator feeding a variable load, variations in oscillator output power are detected, and used to produce an error signal which controls the frequency of the oscillator. The output of an oscillator for feeding an electromechanical transducer is measured by a wattmeter, the resulting output from which is added to a D.C. bias and fed to a circuit, Fig. 2, which cycles through four phases under the control of bi-stable circuits 125, 70. During the first phase, transistors Q 2 , Q 6  are rendered non- conductive and Q 7  is rendered conductive by the bi-stable circuits and input signals are fed via Q 1 , phase splitter Q 3  and upper channel Q 4 , Q 9  to the integrating amplifier. During the second phase, bi-stable 125 reverses the states of Q 6  and Q 7  so that signals of opposite polarity are fed via lower channel Q 5 , Q 10  to the integrating amplifier. The resulting output after these two phases is thus either positive, negative or zero depending on whether the first phase signal is greater than, less than or the same as the second phase signal. During the third and fourth phases bi-stable 70 switches on transistor Q 2  to earth the input and the integrating amplifier is reset by Q 11  during the third phase, or by Q 12  during the fourth phase, depending on whether the output is negative or positive. The positive or negative output is used to control a bi-stable circuit (180, Fig. 1, not shown) which determines whether a function generator (190) sweeps the oscillator frequency upwards or downwards. A number of such systems may be employed in cascade.
Patent GB-1417849-A (GB)
Title: Control systems
IPC: H03M11/08
Filed: 1972-12-20
Abstract: 1417849 Electric selective signalling H KAFAFIAN 20 Dec 1972 [26 Jan 1972] 58854/72 Heading G4H The invention concerns systems for operating program-controlled machines which are particularly adapted for use by the disabled. Depression of two switches SW1-SW7 provide X, Y co-ordinate inputs to a coding matrix, e.g. an ASC11 code converter and solenoid driver for a typewriter (Figs. 2, 3, not shown). Depression of e.g. SW1 for the X-co-ordinate sends a signal 1-1 to a buffer IBC1 and a signal 2-1 to a common buffer CIBC. IBC1 outputs a signal 3-1 through a gate Z1A (initially open) to a memory Z1B whose outputs 6-1, 5-1 pass to one of seven output drive circuits 7 and a logic circuit Z8. As soon as Z8 receives a signal it causes a "first co-ordinate entered" lamp 12 to be lit and closes gates Z1A-Z7A via output 26. Release of SW1 causes CIBC to output a signal 14 which, with an output 16 from Z8, enables a gate Z9A to cause a control Z9B to produce a signal 18 which enables gates Z12A-Z12G. Depression of the Y-co-ordinate switch (e.g. SW1) causes the above procedure to be repeated, except that signal 3-1 passes through gate Z12A to the corresponding drive circuit 22. Upon release of this switch the input to CIBC is again removed, and its output now changes: this is differentiated at 21 to enable a gate Z10C whose other input is fed by a signal 34 from gate Z9A. Output 28 from gate Z10C is used to clear memories Z1B-Z7B through a logic element Z11C (output 28), whereupon Z8 reverts to its initial state so that lamp 12 is extinguished and gate Z9A blocked. A further switch SW8 can be used in conjunction with Z11C to reset Z1B-Z7B in the event that the first switch is wrongly selected.

A fleece is made by air-laying continuous filaments on a moving conveyor belt, adding water to the fleece to temporarily strengthen it (by virtue of the surface tension of the water acting on the filaments), removing the fleece from the conveyor belt, permeating with a binder and drying the process prevents binder accumulating on the conveyor belt. The binder can be added after the water has been sprayed into the fleece and whilst it is suspended between two conveyors. The fleece can be passed through a heater whilst it is suspended to cure the binder. The fleece can be dried on another conveyor belt or on a drum drier. The binder can be polyacrylic or a latex. The filaments can be freshly spun and separated using electrostatic or aerodynamic forces. Alternatively drawn filaments forwarded from creels can be used. The filaments can be made of polyamides, polyesters, or polyurethanes.

Title: Water for nutrient feed systems
IPC: A01G31/00
Filed: 1978-08-23
Abstract: Water fed to or circulating in a nutrient film system is treated with a pathogenicide to reduce pathogen problems with plants growing in the system. For example the pathogenicide can be fed to the system as a solid or as a liquid concentrate, notably to the sum tank of the nutrient film system. Preferably the pathogenicides are used in conjunction with nutrients for the plants and the invention also relates to solid mixtures of the plant nutrients and the pathogenicide. In some cases it may be necessary to isolate the pathogenicide from the nutrients to prevent chemical interaction between them. For example one or more of the components can be given a coating or the pathogenicide can be put up in one compartment of a multi compartment container used to feed the nutrients to the nutrient film system.

Title: Feed bridge for a telephone line
IPC: H04M19/00
Filed: 1979-01-04
Abstract: In an electronic feed bridge, such as used in a telephone exchange for supplying direct current to the line, it is known to use transistor gyrators between each "leg" of the line and the power supply terminals. However, such transistor gyrators are liable to act as amplifiers for any noise which originates on the d.c. supply. To overcome this each gyrator's transistor (T, T', Fig. 5) has an inverter feed to its emitter circuit from the other gyrator's transistor. By suitable proporting of these inverse feed connections, the noise due to the d.c. supply is substantially eliminated. <IMAGE>

Title: Improvements in or relating to binary adder circuits
IPC: G06F7/50
Filed: 1979-03-13
Abstract: A binary adder 12 has a switching circuit 16 connected to one of its inputs.

The invention is useful in an array processor, for performing additions and shifting operations in which an input from a neighbouring processing element N,E,W,S selected by a multiplexer 24 is conveyed by the adder 12 to its sum output for gating into the Q register, and the previous state of the Q register emerges at the carry output for transmission to a neighbouring processing element. <IMAGE>
