IPC: D01D1/10
Filed: 1953-03-04
Abstract: In an apparatus for melt-spinning or extrusion, a filter pack, located between a pump such as a gear pump, a ram or screw (or a combination of a gear pump with a ram or screw) and a spinneret or die, comprises one or more coherent, shaped porous metal blocks or plates, preferably of sintered stainless steel powder.  The block or plate may be a porous casting machined to the required shape, and may have a permeability such that it will pass a silicone oil of 2000 poises viscosity at 20 DEG  C. at a rate of 1 lb./hour/sq. inch under pressures ranging from 100-5000 lbs. per square inch at 20 DEG  C. The block may be in the shape of a hollow cylinder or cup.  A filter pack may consist of several porous plates in series, the pore size of each plate being less than that of the preceding plate in the direction of flow of the melt.  In comparative examples 70 denier filament polyethylene terephthalate yarn is spun in a melt spinning apparatus provided with a porous sintered metal filter consisting of a plate 0.125 inch thick and 2.5 inches diameter giving a pressure drop of 150, 200 or 300 p.s.i. respectively when tested at 20 DEG  C. with silicone oil of 2000 poises viscosity at 20 DEG  C. at 1 lb./per hour/per sq. inch rate of flow.

Title: Gun of electrical projector type
IPC: F41B6/00
Filed: 1942-08-01
Abstract: 560,896. Photo-electric and cathoderay control of guns. WHITEHORN, H. K. Aug. 1, 1942, No. 6314. [Classes 39 (i) and 40 (iii)] [Also in Group XXI] Relates to electromagnetic guns in which the projectile is attracted towards the centre of a coil system excited by unidirectional current which is switched off when the projectile approaches the centre of the coil system. According to the invention in order to avoid the arc formed when the circuit is broken, the projectile is first attracted by one or more auxiliary coils excited by direct-current and, when the projectile is nearing its central position in the main coil, this coil is fed with unidirectional variable current obtained from a strongly-charged condenser arranged in a circuit .the characteristics of which are such that R<2> is equal to or greater 4L than -, where R is the resistance, L the C inductance, and C the capacity of the circuit. In these circumstances, the discharge current rises and falls but is unidirectional and has a minimum value when the projectile is at the centre of the main coil. Fig. VII shows a simple form of circuit with condenser C charged with direct current through switches S which are opened after the condenser has received a powerful charge. The condenser discharges to feed the main coil G through contactors W and transformer T. The contactors W are closed by timing means controlled by the projectile, and no arc is formed when the contactors W are opened with the current at its minimum value. Fig. I shows a gun barrel 2 with projectile 1 and a single coil 3 arranged to function both as a main and auxiliary coil. The timing may be controlled by the passage of light or electronic rays through passages 4, 5 directed across the gun barrel 2, the rays acting on the contactors through a relay in known manner. Fig. III shows a gun barrel 11 with projectile 1 the main coil 9 and auxiliary coil 10 being shrouded by a laminated iron sleeve 8. Specification 364,230, [Group XXX] is referred to.

Title: Data enciphering apparatus
IPC: G06F21/14
Filed: 1976-02-18
Abstract: 1501073 Pseudo-random sequence generators NCR CORP 18 Feb 1976 [28 Feb 1975] 06385/76 Heading G4D [Also in Division H4] A data bit enciphering apparatus comprises pseudo-random bit sequence generator, means receiving the sequence for logically modifying it in a varying manner, means for logically combining the modified sequence with the data bits and means for shuffling the resulting sequence. The arrangement is stated to be advantageous where a high degree of security is not required such as in auto-teller and cash dispensing machines. The pseudo-random sequence generator (Figs. 2A and 2B, not shown) include four 4-stage serially connected shift registers (12, 14, 16, 18) with the parallel outputs connected to a pin board. Jumpered connections provided in a plug (152, Fig. 5, not shown) connect the outputs to three similar logic circuits (40A, 40B, 40C, Fig. 3A, not shown) each comprising NAND gates 43 having erect and inverting inputs and each connected to a parity circuit (41A) so that three alternative random sequences are provided (lines 302, 304, 306). In Fig. 3B (not shown) one of these is selected and added in an Exclusive-OR gate (60) with the clear text to provide enciphered text (at 310). The resulting sequence is then fed into a series of shift registers (Fig. 4A) which has input and output connections from various stages interconnected so as to shuffle the digits of the sequence, the interconnections being made in a further jumper plug (154, Fig. 5, not shown). The first block of any ciphered text transmission comprises 16 synchronizing bits and 40 data bits which determine the starting configuration of the registers. For deciphering the process is used in reverse.

Title: Color television picture tube
IPC: H01J29/00
Filed: 1970-02-10
Abstract: 1,249,798. Colour television tubes. SONY CORP. 10 Feb., 1970 [20 Feb., 1969], No. 6437/70. Heading H1D. [Also in Divisions H3-H5] In a colour television tube of the shadow mask type, misregistration due to thermal expansion of the shadow mask or grid is prevented by providing an auxiliary deflection coil behind the main deflection coil and energised in opposition to it to a variable extent by means including an inductance having a core the permeability of which reduces as its temperature increases; this core is mounted on the neck or the cone of the envelope so that as the shadow mask heats up the cone also heats up thereby effectively moving the centre of deflection to compensate for the expansion of the mask. In one arrangement, Fig. 3 (not shown), the inductance is in parallel with the auxiliary coil and both are in series with the main deflection coil so that the current through the auxiliary coil reduces with increasing temperature of the tube. In another arrangement, Fig. 6 (not shown), the main coil is in series with the primary winding of a transformer with a core whose permeability decreases with increasing temperature, and the secondary winding of the transformer feeds the auxiliary coil. In a modification of this arrangement, Fig. 7 (not shown), the auxiliary coil is also energised from an adjustable D.C. supply for centring the beams, an inductance and a capacitor being included to isolate the D.C. supply, and the transformer secondary winding from each other. If the shadow mask is in the form of a grid with vertical apertures it is necessary to compensate only the horizontal deflection.

Title: Improvements in means for working internal combustion engines with heavy oils
IPC: F02M31/08
Filed: 1922-03-06
Abstract: 197,771. Hall, H. L. March 6, 1922. Cylinders receiving liquid fuel; vaporizers, external.- In an engine employing electric or equivalent ignition, and which is constructed to be run either with carburetted mixture or liquid fuel injected into the cylinder, a heater is provided for the fuel, consisting of a coil of pipe e, Fig. 5, in the exhaust pipe, wound round an inner perforated tube d through which the exhaust escapes to the atmosphere. A pyrometer is provided in the exhaust pipe a, and the temperature of the fuel may be regulated by by-passing some of the hot gases. The piping e may be heated by a blowlamp at starting, and means for heating the main fuel tank may be provided. The fuel is supplied by a pump, any excess being returned by means of a spring-loaded valve situated in the supply pipe to the coil e. A non-return valve separates the coil from its supply pipe. The fuel is maintained at a high pressure in the coil e which is in permanent connection with the injector c through the pipe v. Pressure gauges are provided both for the fuel in the heater and that in the pipe supplying it. The amount of fuel injected is regulated by varying the duration and extent of the opening of the injection valve, for which purpose an axially slidable cam-shaft l is employed, actuated from a suitable regulating lever. This lever is also connected to the throttle valve p of a carburettor, so that when fuel is cut off from the latter, the air which is aspirated therethrough is regulated in amount as the quantity of fuel injected into the cylinder is varied. Fuel may be supplied to the carburettor at starting, or when otherwise desired, through a rotary plug or cock, which is connected to anothersimilar cock controlling the supply of heavy fuel to the heater so that as one fuel supply is turned on, the other is cut off. These valves are also connected to a distance piece which is withdrawn from between the axially slidable cam e and its actuating member when the heavy fuel is cut off' and light fuel is being supplied to the carburettor, the withdrawal of the distance piece allowing the cam shaft to move into a position at which no. opening of the injection valve takes place. The engine may be run on a mixture of light and heavy fuels, in which case the carburettor is set to supply a very weak mixture, which is suitably enriched by the fuel injected through the injector c. Light and heavy fuels mixed may be supplied to the heater, or the latter together with the pump and injection valve may be duplicated, different fuel being supplied by each set. The injection valve c comprises a ball f normally held on its seat, as shown, by a rod h, which ball is adapted during inflation to seat on the guide for the rod h, thus preventing leakage of fuel past it. The fuel is sprayed through a non-return valve m on to a sparking plug o.
