Title: Improvements relating to machines for making friction grip threaded members
IPC: B23G9/00
Filed: 1953-01-16
Abstract: 728,938. Shearing rods. NYLOK CORPORATION. Jan. 16, 1953, No. 1408/53. Class 31 (1). [Also in Group XXII] In automatic machines for making friction grip nuts 10 (see Group XXII), rods 16 of nylon are successively cut into short lengths 36 and inserted into side holes 23 in the nuts by a pneumatically operated shearing attachment. The rod 16, continuously urged forward by a friction wheel 18, passes through a hole 22 in a vertically reciprocating knife blade 21 into engagement with a stop 25 when the blade 21 is at its lowermost position. On raising the blade 21 by a pneumatic ram 27 the slug within the hole 22 is sheared off and raised to a position opposite the hole 23 in the nut. A pin 29 on a cross head 30 actuated by a pneumatic ram 33 and passing through the hole 22 in the blade pushes the slug 36 into the nut.

Title: Means for grid-control in converting arrangements
IPC: H02M1/04
Filed: 1936-01-17
Abstract: 469,084. Converting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Jan. 17, 1936, No. 1594. Convention date, Jan. 22, 1935. [Class 38 (ii)] In a converting arrangement means are provided for obtaining a grid control voltage which is proportional to the difference between the currents of two conducting anodes, one of which is succeeding the other. In an inverter as shown a current transformer 7 has two primary windings connected in opposition in the anode circuits of the discharge device 1, and a secondary winding connected across a resistance 8 in the grid circuit. Since the transformer 7 is of the type having a small magnetizing current compared with the primary current the voltage across the resistance 8 will be proportional to the difference of the anode currents. In addition a peaky voltage may be injected into the grid circuit from a saturated transformer 11, supplied through a phase shifting transformer 9, giving a positive peak at the moment of ignition for control purposes and a negative peak at the moment when the arc is extinguished for deionization.

Abstract: 764,219. Engine valve-gear. AKTIEBOLA. GET SVENSKA KULLAGERFABRIKEN. Jan. 19, 1955 [Jan. 20, 1954], No. 1607/55. Class 122 (2). [Also in Group XXVIII] In a multi-cylinder pump delivering liquid at constant pressure, mechanically-independent differential pistons 11, 12 and 13, 14 are actuated by compressed air &c. supplied through a main 20 past a piston valve 19 which directs the air alternately to a constant stroke piston (13, 14) and a variable stroke piston (11, 12): the main also supplies air to the lower ends of auxiliary pistons 32, 33 which return the pistons (11, 12) (13, 14) to their starting positions for their working strokes. The undersides of the upper parts 12, 14 of the main pistons are always exposed to atmospheric pressure through ports 38, 39. When the piston 13, 14 reaches the end of its stroke, the reduced upper end of the auxiliary piston 33 opens to atmosphere a port 40 communicating with a chamber 22 at the right hand end of the piston valve 19, the opposite end of which is constantly exposed tc pressure lower than the mains pressure and determined by a needle valve restriction 340 and a relief valve 34. This pressure moves the piston to the right, there being a moment when both cylinders 15, 16 are open to the main 20 as a land 31 on the valve passes forked passages 29, 30 leading from the main 20. Ports 41, 44 in the valve casing open the non-operative cylinder 16 or 15 to the atmosphere. When the auxiliary piston 33 reaches the top of its stroke its supply passage 46 is opened to the port 40 and mains pressure applied to the chamber 22 to actuate the valve 19. Permanent magnets 25, 26 hold the valve in its end positions.

Title: Improvements in or relating to modified nitrocellulose coating compositions and fabrics coated therewith
IPC: C09D101/18
Filed: 1945-01-26
Abstract: A cellulose derivative composition suitable for coating fabrics comprises 10-33 per cent of cellulose nitrate, 50-80 per cent of a polyester alkyd resin, and 7-33 per cent of a ureaformaldehyde resin modified with a monohydric alcohol, these values being based on the weight of the composition exclusive of any pigment or volatile solvent.  The polyester alkyd resin is selected from the group comprising polyesters of the dihydric alcohols:-propylene, ethylene, diethylene, triethylene 1-4-butylene, and 1-3-butylene glycols with the dicarboxylic acids:-succinic, maleic, glutaric, adipic, azelaic, and sebacic acid.  After application of the composition and removal of solvent, the coated fabric is preferably subjected to a heat curing treatment at 210-200 DEG  F. Fabrics so treated are rendered resistant to penetration by organic solvents, vapours, and war-gases. An acidic hardening catalyst, e.g. n-butyl acid phosphate, phosphorus pentoxide, hydrochloric acid, or ammonium chloride may be included in the composition.  In an example, cotton fabric is passed through heated calendar rolls under pressure to lay the nap and is then given a plurality of coats of cellulose nitrate composition on both sides. The composition comprises cellulose nitrate, butanol modified urea-formaldehyde polymer, diethylene glycol sebacate, n-butyl acid phosphate, non-alkaline pigments, silica gel, blown castor oil, ethyl acetate, ethyl alcohol, n-butyl alcohol, and butyl acetate.  After each successive coat the volatile solvents are removed by passing the coated fabric through a heated chamber. The fabric is then given another heat treatment by passing between heated rollers under pressure.  Surface coatings of similar composition but containing a higher proportion of cellulose nitrate, pigments, and silica gel are then applied, and the coatings are dried and heat cured.  The coated fabric is impermeable to mustard gas and many organic liquids.  The fabric may finally be dusted with talc.  In another example, upholstery material is obtained by applying several coats of the cellulose nitrate composition to a woven sateen cotton fabric.  The material is resistant to cracking at low temperature and does not become sticky at 180 DEG  F.
