Title: Improvements in or relating to the method of and apparatus for determining the position of concealed guns or other sound producing devices
IPC: G01S1/72
Filed: 1925-03-19
Abstract: 248,189. Schier, J. March 19, 1925. Locating sounds. - In apparatus for locating guns or other sound-producing devices, in which microphones located at various points transmit current impulses to a central station where the impulses are recorded on a paper strip, the voltage of the impulses is increased bv transformers, the resulting alternating impulses are rectified and amplified by thermionic devices, and the direct-current impulses thus produced actuate recording pencils through electromechanical means. The electromechanical recording device preferably comprises a Johnsen-Rahbek device, having a semi-conducting revolving roller around which pass thin metal bands, the spindle of the roller being connected to the movable contact of a potentiometer and to the central point of a star-connected series of high resistances, and each metal band being connected to the outer end of one of the resistances and to the anode of one of the amplifiers. The microphones A, B, C are in circuit with batteries and with the primary windings of transformers E, F, G. One secondary terminal of each transformer is connected to the grid of one of the thermionic valves e, f, g and the other terminal to the corresponding filament. The filaments are connected in parallel to a battery H and to the negative terminal N of a battery of 120 volts. The anodes L of the valves are connected in star connection through high resistances W<1>, W<2>, W<3> to the movable contact Q of a potentiometer P connected across the high-voltage battery. The centre point of the star is connected to the spindle R of a revolving agate roller S, around part of the circumference of which pass thin metal bands T<1>, T<2>, T<3>. Each band is connected to the outer end of one of the resistances, and is attached to the upper end of a lever t<1>, t<2> or t<3>, the lower end of the levers carrying pencils s<1>, s<2>, s<3>, which bear against a paper strip moved at constant speed over a cylinder w. The metal bands are held against the agate roller by springs u<1>, u<2>, u<3>, the tension of which is adjustable. An additional pencil may be used to indicate the speed of the paper strip. Preferably the ratio of the speed of the latter to the velocity of sound is equal to the scale of the map on which the positions of the microphones are marked, so that the actual distances apart of the records of one sound on the strip are equal to the differences in the distances on the map of the source of the sound from the microphones affected.

Patent GB-1341679-A (GB)
Title: Screw press
IPC: B30B1/18
Filed: 1972-02-18
Abstract: 1341679 Forging NOVOPRESS GmbH PRESSEN UND PRES8WERKZEUGE & CO KG 18 Feb 1972 [3 March 1971] 7529/72 Heading B3 [Also in Divisions B5 and F2] A screw press comprises a screw 4 which drives a ram 2 downwardly and is driven through a releasable coupling 6 by a continuously rotating flywheel 5, the coupling being released on the angular velocity of the screw falling below, and/or on the screw suffering an angular retardation exceeding, predetermined limits. Hydraulic cylinders 9 withdraw the ram upwardly, and also initially rotate the screw to couple it to the flywheel. The coupling may comprise centrifugal weights (12, Fig. 2, not shown) mounted on the screw for movement radially of the screw, the weights which are spring urged inwardly having a friction lining to engage the interior of a drum extending axially from the flywheel. Alternatively (Figs. 3 and 4, not shown) to reduce the inertia of the screw, the weights may be mounted on levers pivoted to the screw adjacent the axis thereof, the lever being spring urged together and connected to further levers which can push coupling members outwardly or axially to engage the flywheel. In another embodiment (Fig. 5, not shown) the weights comprise balls movably in radial grooves in a plate fixed to the screw, outward movement of the balls causing a clutch plate (48) to engage the flywheel. In Fig. 7, the centrifugal weights 62 and friction pads 63 are mounted on levers 66 pivoted to a plate 64 fixed to the screw 4. The weights are so positioned that a retardation of the screw tends to pivot the levers 66 inwardly against the centrifugal outward force of the weights. The embodiment of Figs. 2-5 may be modified so that the centrifugal weights also have a component of motion in the tangential direction so that a retardation of the screw tends to declutch the coupling. In Fig. 6, spring plates 54 mounted on the screw are flexed outwardly to engage the flywheel by air pressure between them. Compressed air is introduced through a non-return valve 60. An air outlet 59 is normally closed by a nut or slide 52 and can be opened by a release of the force of levers 56 which carry centrifugal weights and/or by a retardation of the screw causing nut 52 to rotate. Alternatively outlet 52 may have an electrically actuated valve controlled by an electrical device which measures the angular velocity and/or retardation of the screw. In another embodiment a feeler device measures the stoppage which is a measure of the angular retardation between the two parts of the coupling or of an auxiliary coupling and is connected to a release device.

As a further modification, the movable valve element 7 which terminates a stainless steel spindle 6, has a flat end 7a coacting with a slightly resilient seat, e.g. of nylon.

March 9, 1934, No. 7556. Convention date, March 10, 1933. [Class 38 (v).] Magnetic blow-outs have their coils 13 in the form of a spirally-wounc conductor, the inner end 21 of which is dividec and the ends 19, 20 so formed are brought out on opposite sides to provide circuit connections. In building the coil, one end is divided and the limbs spread apart so that the coil can be wound between them.

Title: Heat shrinkable anti-fogging films
Inventor: SPILLERS FRANK WAYNE
IPC: C08K5/06
Filed: 1970-02-18
Abstract: 1,245,069. Making heat shrinkable polyolefin films. DOW CHEMICAL CO. 18 Feb., 1970 [19 Feb., 1969], No. 7823/70. Heading B5B. Heat shrinkable polyolefin packaging film is produced by heating a polyolefin composition containing an anti-fogging additive to a temperature at or above its melting point, extruding the composition to form a tube or a sheet, treating the tube or sheet with high energy ionizing radiation, stretching and cooling the sheet or tube to provide a heat shrinkable film and exposing the film to corona discharge treatment at a power level of from “ to 20 watts (preferably ¢ to 8 watts) per square foot (0À09 sq. metre) per minute. The polyolefin may be polyethylene. The anti-fogging agent may be an alkylphenolpoly - (ethyleneoxy) - ethanol. The proportion of the agent in the film may be 0À25 to 1À5% (preferably 0À4 to 0À9%) by weight based on the total weight of the film. The composition may be shaped into a tube by tube extrusion or into a sheet by slot extrusion. In an example, a blend of 100 parts by weight of a copolymer of 94À5% by wt. of ethylene and 5À5% by weight of vinyl acetate, 5À4 parts by weight of polyethylene, 0À2 part by weight of finely divided calcium carbonate and 0À8 part by weight of nonyl-phenoxypoly (ethyleneoxy) ethanol (having about 4 ethyleneoxy units) is extruded at 200‹ C. to form a tube 6 inches in circumference and having a 35 mil. thick wall. The extruded tube is cooled to room temperature in water and is subsequently irradiated with high energy ionizing radiation at a dosage of 8 Megarads employing a 750 kilovolt electron generator beam. After irradiation, the tubing is heated to about 100‹ C., inflated with air to expand it to a diameter of about 30 inches and simultaneously stretched longitudinally at a stretch ratio of 5-7. The tubular film thereby formed has a wall thickness of about 0À6 mil and is passed over a rotating metal drum having a 35 mils thick coating of polyethylene terephthalate. One surface of the flattened tubular film is given a corona discharge treatment of 3À2 watts per square foot per minute and the other surface of the flattened tubular film is then treated in the same manner. Samples of the film are passed through the treating apparatus 3, 6 and 9 times respectively. In other examples, a large number of specified anti-fogging agents are used. The polyolefins used may be copolymers of up to about 30% by weight of acrylic acid (or methacrylic acid) with ethylene, copolymers of ethylene with vinyl esters, alkyl acrylates and the like.
