IPC: H01H37/66
Filed: 1955-05-20
Abstract: 788,612. Switches. LUCAS (INDUSTRIES), Ltd., J. April 19, 1956 [May 20, 1955], No. 14635/55. Class 38 (5). A bimetallic switch for preventing overload of a motor actuating a vehicle windscreenwiper, comprises a strip d consisting in part of iron or having an iron part attached to it, secured to a rigid metal strip a and carrying a contact co-operating with a contact on a further rigid metal strip g. The strips d, g have terminal lugs f, i, respectively, and strips a, g are insulatingly carried on a clip b for securing to the motor housing c, Fig. 4, in a position adjacent the field pole j and armature k. In use, the stray field of the motor holds the contacts closed until the deformation of the bimetal under overload and/or overheating produces quick separation of the contacts. The switch may be in series with the armature only or with armature and field (Fig. 5, not shown).

Title: Process and apparatus for hat making
IPC: A42C1/02
Filed: 1947-06-05
Abstract: 634,406. Hardening hat bats. HAT CORPORATION OF AMERICA. June 5, 1947, No. 14904. Convention date, Feb. 21, 1939. [Class 63] An apparatus for starting hat bats in two stages comprises a first phase machine which imparts a slow rolling and light pressing action together with a flow of hot water upon a roll of hat bats and a second phase machine which subjects each of said rolls to a relatively faster rolling and relatively greater pressing action, after said rolls have been soaked in water on completion of the first stage working. The first phase machine is generally similar to that described in Specification 339,111, [Class 63], with the addition of an adjustable spring mechanism which supplements the weight of the pressing rollers, and is adapted to be released by the timing mechanism which controls the main rollers, Fig. 6 shows a further variation in which longitudinally spaced kneading rods 19 on one of the roller drums 21 are relatively thicker and spaced further apart than the rods 18 on the other drum 20, and in which each or both of the drums is covered with a rubber mat 81 having longitudinally extending ribs 82. The second phase machine, Figs. 10 and 11, includes a main frame 90 supporting a main roller 94 having a rope spirally secured thereto, and a main roller 97 with wood strips 98 secured thereto. Disposed above the rollers 94, 97 is a retractable frame 106 with side plates 107 pivotally mounted on a shaft 108 for the roller 97. The frame 106 supports a pressure roller 104 provided with wood strips 105, and the rollers 94, 97, and 104 are driven by chain and sprocket gearing which is driven through the clutch mechanism 122 slidably mounted on the shaft 108 of the roller 97 and engageable with a pulley 123 driven by a prime mover. A fluid-operated cylinder and piston unit 112 forces the roller 104 on to a roll 100 of hat bats, with a pressure determined by the setting of a blow off valve 134, when fluid is directed along a pipe 118 to the bottom of the piston cylinder unit 112. Fluid directed along the pipe 121 enters the top of the cylinder and piston unit 112 to force the roller 104 to its inoperative position shown in Fig. 11. A starting handle 176 sets a tripping pawl 161 of a timing mechanism 143 and operates a valve which directs fluid to the pipe 118 so that the pressure roller is applied to the bats. The movement of the retractable frame 106 sets in motion a mechanism which causes the clutch 122 to engage the pulley 123. When the machine has run for a predetermined time the timing apparatus trips the pawl 161 which operates the valve to cause the fluid to enter the pipe 121 and the retractable frame to move to the inoperative position so that the clutch 122 disengages the pulley 123.

Abstract: 545,193. Coating surfaces. DU PONT DE NEMOURS & CO., E. I. Oct. 5, 1940, No. 14909. Convention date, Oct. 4, 1939. [Class 95] [Also in Group IV] Drying-oils are produced by polymerization of a diolefine in an inert hydrocarbon solvent in presence of at least about 4 per cent. of an alkali or alkaline earth metal or hydride thereof at 110-170‹ C. under pressure. Examples describe the polymerization of butadiene, with benzene and of a butadiene-butylene mixture with or without benzene by means of sodium, and of butadiene with benzene by means of sodium hydride. A small proportion of a reactive unsaturated substance such as indene, dihydronaphthalene, chloroprene, styrene, viyl acetate, methyl methacrylate, cyclopentadiene and cyclohexadiene may be added to modify the properties of the product. Solutions of the polymers are suitable for coating purposes, especially those which involve baking, especially as an undercoat; when a vinyl chloride-vinyl acetate inter-polymer is employed as a top coat the butadiene polymer solution may have an addition of a small proportion of a methacrylic acid ester such as isobutyl methacrylate to promote adhesion to the top coat. The Specification as open to inspection under Sect. 91 gives the lower limit of temperature as 100‹ C. This subject-matter does not appear. in the Specification as accepted.

Title: Improvements in or relating to thermionic valves
IPC: H01J5/54
Filed: 1937-05-31
Abstract: 501,515. Two-part couplings. ROBINSON, E. Y., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 31, 1937, Nos. 15124 and 15599. [Class 38 (i)] The octal base for thermionic valves is adapted for various valves having glass envelopes by arranging the connections to suit lead-in wires passing through a flat pinch and to effect shielding, and providing means to prevent insertion of a standard metal envelope valve in the holder wired for such modified connections. The cap is provided with a central spigot 2 having one or two keys 3 the spigot being of larger diameter than that of the metal valve and being made hollow to accommodate the exhaust tube of the valve. The pins are asymmetrically arranged, either on an ellipse or oval or on a pitch circle of larger diameter than that of the metal valve and on which the spaces between the pins subtend unequal angles. The unequal spacing may be effected by arranging the filament pins to subtend an angle of 55À5‹ which embraces the key 3, the other pins being equally spaced. In order to effect shielding between the pins connected to the filament, anode, and certain grids such pins alternate with pins connected to the cathode, screen grid, or metal coating on the envelope or with pins unconnected within the valve, that can be earthed in the receiver. Where such unconnected pins are not required for shielding the pins may be omitted.

Abstract: 440,241. Multiplex signalling. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Chesnut, R. W. ; 115, Inwood Avenue, Crane, R. E.; 446, Valley Road, both in Upper Montclair, New Jersey, and Huber, G. H.; 332, East 7th Street, Brooklyn, New York, both in U.S.A.) May 24, 1935, No. 15225. Con. vention date, May 26, 1934. Drawings to Specification. [Class 40 (iv)] In a single line multi-channel signalling system wherein the different channels consist of different frequency bands, the signals are transmitted over the various channels at energy levels dependent on the attenuations of the respective channels and on the level of the combined interference due to noise inherent in the respective channels and to the presence of signal currents in other channels. The noise inherent in a channel includes all interference not due to operation of the line itself such as static, resistance noise, cross talk from other lines and induction from power lines. The interference due to signals in other channels on the same line comprises modulation products consisting of harmonics and combinations of frequencies due to non- linear characteristics of the lines and associated equipment. The invention enables more or higher grade channels to be obtained from a given line or the same number and grade to be obtained from a cheaper line of higher attenuation. The Specification contains a mathematical discussion of the problem and shows how to calculate the transmitting levels assuming specified margins for signal level over combined interference level and for modulation products below the natural noise level. In a two-way multi-channel system using different bands for the two directions, the modulation products in a channel due to other channels in the same direction and to the corresponding opposite bound channel may be neglected. Different combinations of opposite bound channels should also be considered since although interaction between opposite bound channels of a pair is not important, interaction between different pairs may vary for different combinations.
