Patent GB-1592255-A (GB)
Title: Method of continuous casting of metallic strips
IPC: B22D11/06
Filed: 1977-10-11
Abstract: Molten metal is applied under pressure, through a slit nozzle (10), to a moving cooling body (7). The slit nozzle (10) is arranged directly adjacent to the surface of the cooling body (7). The cooling body (7) moves past the slit nozzle (10) at a surface velocity of 100 to 2000 m/min. The distance between the slit nozzle (10) and the surface of the cooling body (7) is 0.03 to 1 mm. These dimensions permit high-speed production of continuous polycrystalline metal strips and amorphous metal strips with hitherto unachieved dimensions of isotropic thickness and other isotropic properties, e.g. magnetisability. <IMAGE>

(1) or the expansion: - 4F(#,#) = (a -1  -a 1 )(b -1 -b 1 ) + 4a o b o sin<SP>2</SP># ... (2) A first embodiment evaluates F(#,#), using the first expansion above, to monitor whether the current in a power line leads or lags the voltage by more than a pre-set amount. The current a and voltage b, Fig. 2, of a line 10 are sampled and digitized 13, 14, the products occurring in the first expansion (1) are evaluated 16 and appropriately combined 17, and the resulting signal is compared with a pre-set threshold. For example if the current does not lead or lag the voltage by more than 90 degrees then F(#,#) is positive: otherwise it is negative. A second embodiment, Fig. 4 (not shown) evaluates the same function for the current and voltage in a power line but uses the second expansion (2) above. In a third embodiment, Fig. 3 (not shown) the current in a single line is sampled at two points, so that if the line is fault free the samples will be identical, and the differences between pairs of samples taken at the same time are taken as the values of both the a and b samples above.

Title: Process for the improvement of lacquers
IPC: C09D7/80
Filed: 1959-12-23
Abstract: Finely-divided, pyrogenically prepared silicon dioxide is added to a lacquer in the form of a liquid dispersion with a solid content of at least 25% by weight, preferably 30-45% by weight, in a dispersing agent with a predominantly polar character.  The dispersing agent may contain polar and non-polar groups or may be a mixture of polar and non-polar substances.  In a preferred method, the silicon dioxide dispersion is added to diluted lacquer, and this mixture is then added to the lacquer. Pyrogenically obtained silicon dioxide consisting predominantly of particles of about 5 to 100X10-16 mm. and specific surface about 200 m2/g. may be used.  Specified dispersing agents include methanol, ethanol, n-propanol, isopropanol, isanol (60% n-butanol plus 40% isobutanol, by weight), ethylene glycol monomethyl ether, ethylene glycol monobutyl ether, and the following mixtures (all proportions by weight): 90/10 ethanol/benzene, 90/10 ethanol/benzine, 90/10 ethanol/toluene, 90/10 isopropanol/benzine, 85/15 isopropanol/benzene, and 85/15 isopropanol/toluene.  In an example, a lacquer comprising nitrocellulose, a modified urea resin, dibutyl phthalate, n-butanol, ethyl acetate, n-butyl acetate and toluene is mixed with a diluted lacquer to which a dispersion of silicon dioxide in n-butanol had been added, the diluent used being a mixture of toluene, n-butyl acetate, ethyl acetate and n-butanol. Lacquers so made have good matting power and enhanced resistance to sedimentation.

Abstract: 1329558 Attendance registers F GELDER 14 Sept 1970 [15 Sept 1969] 43878/70 Heading G4T An arrangement for registering the presence of the personnel of an enterprise comprises a first indicator board 1 divided into a plurality of fields 3, each corresponding to a category of work and including display units 4 for representing individual employees engaged on the work category. The first indicator board is electrically connected to a second indicator board 2 having lamps (or rotatable discs) 9 in a matrix arrangement, the rows of lamps being co-ordinated with symbols 7 designating individual employees, and the columns being co-ordinated with symbols 8 designating work categories, to indicate the work categories that each employee can undertake. On starting work of a particular category (e.g. a bonus category, an accounting unit, or a particular location) an employee inserts a punched card 6 into a control unit 5 (or presses an individual button or actuates a light barrier) that illuminates the employee's name or a serial number on a digital countertube. The time spent on that work category is clocked by a counter 11. Simultaneously through the electrical connection from the activated unit 4, the corresponding lamp 9 on board 2 is increased in intensity, dimmed with shutters, or its colour changed. A computer 13 programs the pattern of lamps 9, and selects appropriate employees for substitutes in cases of vacancy in the work categories. The computer 13 stores the starting and finishing times indicated by a clock 10, computes salaries, and operates digital countertubes in a field 12 on board 1, simultaneously setting lamps on board 2 flashing, to indicate absent or present employees. A counter is provided for indicating the total number of persons present or absent. The control unit 5 can be used to indicate machine failure; three is one unit per work category, or a single unit for overall control.

Abstract: 1,056,758. Hydraulic transmissions. J. H. CHILD. Feb. 1, 1965 [Nov. 11, 1963], No. 44373/63. Heading F2C. [Also in Division F1] An hydraulic transmission comprises a centrifugal pump 1 having radial vanes 1B and a casing 1A which are fast with an input shaft 1C, the pump supplying liquid through tubes 3D to a stationary tube 2G on which a motor sleeve 2B is slidably and rotatably mounted, the other end of the sleeve 2B being accommodated in a bore 2 of the input shaft 1C. The liquid passes through the sleeve 2B and a valve 2C at the end thereof to the inlet of the pump. A static pressure is maintained in the system by compressed air supplied under the control of a valve 3H to act on a piston 3J in the tube 2G. The motor sleeve 2B is formed with an extension 2F formed with a cam face 3 engaging a radially spring-loaded stop 3A on the tube 2G, a spring 2K being fixed at its ends to the sleeve 2B and the tube 2G to provide axial and torsional loading. Initially, liquid is circulated by the pump through the open valve 2C and the static pressure on the end 4 of the sleeve shifts the sleeve to the right, the sleeve rotating during this movement due to the stop 3A and cam surface 3, thereby winding up the spring. Rotational movement continues until the stop 3A enters a slot 3K having an inclined base which depresses the stop on further axial movement of the sleeve until the stop is fully retracted and the sleeve freed for reverse rotation by the spring 2K. This reverse rotation closes the valve 2C which comprises pivoted flaps 2D which are closed due to the resistance of the liquid; the pump then tends to reduce the pressure acting on the end 4 of the sleeve and the spring 2K returns the.sleeve to the left with the aid of the momentum of the liquid, ready for another stroke. The axial movement of the sleeve may be converted into rotary movement by known means (not disclosed).

In one embodiment, a flame cutting torch 24 is mounted by a pivotable axle on the end of a shaft 23 which is movable by a rack 22, and pinion drive relative to a carriage 15 which is mounted by rollers on and movable by a rack 14 and pinion drive along an upper jaw member 1. The workpiece to be cut in the form of a steel girder positioned in a building, is clamped between the jaw 1 and a spring loaded lower jaw member 3. The shaft 23 is lowered to cause the torch 24 to cut through the right hand flanges and the web of the girder, after which the shaft 23 is raised until a bar 29 carried by the jaw 1 engages a geneva wheel 31 mounted on the torch axle to cause the torch 24 to pivot downwards. The carriage 15 is the nmoved along the upper jaw 1 which causes the wheel 31 to be engaged by a second bar 29 so that the torch 24 is rotated through a further 90 degrees. Subsequently, the torch 24 is again lowered to cut through the remainder of the girder from its opposite side. The torch movement is controlled by a sensor and microswitches. In another embodiment (Fig. 6, not shown) two cutting torches (42, 43) are mounted on the shaft 23, one on each side of the jaws (41).
