Title: Improvements in or relating to the production of a control value dependent on the deviations of power and frequency from their reference values in an alternating-currentsystem
IPC: H02J3/46
Filed: 1957-04-17
Abstract: 830,624. Automatic control systems for power and frequency. PATELHOLD PATENTVERWERTUNGS & ELEKTROHOLDING A.G. April 17, 1957 [April 18, 1956], No. 12547/57. Class 38 (4). In an arrangement for producing a control value depending on the deviation from a reference value of the power and frequency in an A.C. system, the power is represented by the frequency of an auxiliary voltage, this frequency and the system frequency being counted and compared with reference numbers. The differences are used to produce the control value. Each frequency is separately fed through a circuit such as that of Fig. 1, which is for the system frequency. The two circuits operate intermittently and alternately. The input frequency (e.g. 50 c/s.) is multiplied at V and the output (e.g. 50 kc/s.) fed to a counting circuit R which produces a single pulse output after 50,000 cycles. At N a stable oscillator (e.g. 100 kc/s.) feeds a divider T which produces a pulse output after 1 sec. The time and frequency count pulses are applied to a discriminator D and the difference output, representing frequency error, is applied to gating circuits W+ or W - according to sign. Also applied to these circuits is a train of pulses from variable frequency divider K so that the number of pulses in the gated output at either Z + or Z - represents frequency error. In Fig. 2 the train of pulses is applied to circuit elements Sf or Sp (for the frequency representing power) comprising pulse formers, amplifiers and lowpass filters. The output levels are set by resistors Wf, Wp and the channels give a combined D.C. output at C. Also added at C is a component proportional to the integral control function of the sum of the errors. The output at C is the required control value, which may be used in the control of turbines.

Abstract: 1,120,593. Drills, making self-tapping screws; extruding; heading. TEXTRON INDUSTRIES Inc. 22 March, 1966 [3 Nov., 1965], No. 12586/66. Headings B3A, B3C, B3H, B3N and B3P. A self-drilling and self-tapping screw 30, Fig. 1, is produced by placing a blank in an extrusion die 51, Fig. 5, applying pressure by a punch 57 to extrude a portion 49, Fig. 6, and thus form a flat portion 31, transferring the blank to a heading die (60), Fig. 7 (not shown), and forming a head by punch (62), machining cutting edges 40, 41 on portion 31, and then rolling a screw thread 38 on the shank. The drill point may have the cross sections of any of the Figs. 3, 13, 16, 19, 22, 33, 35, 37, 39 (not shown). In a modification, the drill point 121, Fig. 23, is helically twisted when being operated on in the heading die. The screw head (132), Fig. 26 (not shown), may have an integral washer (131), and if the drill point is to have a larger diameter than that of the screw threads, the end (172), Figs. 30, 31 (not shown), is upset by a tool (176), and then machined along the dotted lines (179). The screw thread may be non- circular in cross-section, Fig. 35 (not shown). The extrusion die has a knock-out pin 58 of rectangular cross-section.

[Class 109.] A wire rope is subjected, after it has passed through the closing die, to a tensile stress comparable with that to which it is subjected in operative conditions, e.g., one-fifteenth of the breaking stress. The rope may be stressed by passing it over pulleys 1 .. 3, one of which is offset with respect to the others, or by direct pull. For this latter purpose, a second capstan PO2 or draught device is provided and a slubbing drum SD is arranged between the capstan PO2 and the usual haul-off drum PO1. The direct pull may be applied after the bending operation. Reference has been directed by the Comptroller to Specifications 274,052, [Class 109, Ropes &c.], and 341,867.

[Also in Division C3] Iron or steel surfaces, e.g. vehicle bodies, are provided with weather resistant coatings by applying, e.g. by spraying a thixotropic, aqueous composition comprising a styrene/ butadiene/unsaturated carboxylic acid copolymer, an organic and/or inorganic thickener and an organic and/or inorganic fibrous material, e.g. to a thickness of 200 and 2000 microns. A primer coating may be applied to the metal before application of the composition. The copolymer preferably forms 30-50% wt. of the dried coating and may comprise 25-85% styrene, 10-65% butadiene and 1-5% of the unsaturated acid which is suitably an acid of 3-20 C atoms, e.g. acrylic methacrylic or maleic. The thickener may be an acrylic ester/acrylic acid system, bentonite or magnesium montmorillonite or silicate. The fibres may be of asbestos, polyamide, polyester or polyacrylonitrile and usually are less than 3 mm. long and from up to 30% of the coating. The composition may also include acrylates, acrylonitriles, alkyd or epoxy resins as well as pigments. The coatings may be stoved.

Title: Improvements in and relating to internal combustion motors and the like
IPC: F01M9/12
Filed: 1923-05-14
Abstract: 224,567. Sandwith, H. May 14, 1923. Valve-gear.-Engines with liquid pistons transmit power to a shaft or pump through a solid piston m, on each side of which is a column k of oil in a tube e. These tubes are connected to the power cylinders g by the bends l, the oil floating on water in the bends l. Two power cylinders g, g<1>, Fig. 15, may be connected to each tube e, the bend l being doubled; these cylinders work alternately. The liquid-fuel injection valve s, Fig. 14, is held on its seat by a spring and is opened by a piston in a cylinder a<3> subject to the pressure in the power cylinder. The valve stem moves in a hollow cone f<2>, balls g<2> being placed between the valve stem and the cone to grip the stem when the ring h<2> is lowered. Similar gripping-devices are used between a rod p<3> and lever d<2>, and between the piston rod g<2> and lever v<2>. As the piston rises, the ring h<2> releases the balls g<2>: then the ring n<2> releases the balls o<2>, and finally the rod p<2> pulls down the cone c<2> and opens the valve, which is held open during the combustion period by the balls g<2>. As the pressure in the cylinder a<3> falls, the piston descends and raises the ring h<2>, releasing the valve s. If the piston did not originally rise sufficiently to open the valve s, through the lever d<2>, the lafter is worked through an auxiliary linkage; this consists of the lever x<2> attached to, or constrained to rest against, the top of the valve stem. In ther rest position, the ring z<2> will be down, so that after the piston rod b<2> has been raised, it will, on descending, be clamped to the cone u<2> and open the valve s; this will close at the end of the movement of the piston. In an engine having two combustion chambers g, g<1>, Fig. 15, at each end of the engine and using pistons u, u<1> floating on the water, the inlet and exhaust valves h, h<1> and i, i<1> are worked through linkage from the pistons u, u<1>. The piston u is connected to a lever d' moving on the fulcrum e<3> and reciprocating the slide g<3>. The pin connections between the piston, connecting- rods c<3>, f<3>, the levers, and the fulcrum are contained in inverted cups. On the power stroke in the cylinder g, the piston u moves down and, through the slide g<3>, pulls down the cam m<3>: as a result, the lever g<3> is moved to the position shown, opening the exhaust valve i and removing the lock on the inlet valve h<1> of the cylinder g<1>. After the explosion stroke, the momentum of the moving parts causes continued movement of the water columns in the same direction, thereby drawing in a charge into the cylinder g<1>. The return movement of the liquid columns first expels the exhaust from the cylinder g and then compresses the mixture in the cylinder g'. The upward movement of the slide g' releases the cam m<3> and thereby closes the exhaust valve i and locks the valve h<1>. A similar gear worked from the piston u<1> works the valves h and i<1>.
