Patent GB-891939-A (GB)
Title: Substituted bisamidines
Inventor: MCKAY ARTHUR FERGUSON
Filed: 1959-11-30
Abstract: The invention comprises bisamidines of general formula <FORM:0891939/IV (b)/1> in which R is a substituted benzyl group containing one or two chlorine atoms, (A) is an alkylene group having from four to twelve carbon atoms, a phenylene, or a tolylene group, and X is an organic or inorganic anion, and a process for the manufacture thereof by reaction of a dinitrile of general formula NC-(A)-CN with a benzenesulphonate salt of a chlorinated benxylamine to yield a dibenzenesulphonate salt, and conversion of the said salt into another salt via the free base, or by passage through a column of anion exchange resin, if desired.  Detailed examples are given. The products have bacteriostatic activity (see Group VI). Benzenesulphonate salts of benzylamines containing as substituents in the benzyl group one or two chlorine atoms are prepared by reaction of benzenesulphonic acid with the appropriate chlorobenzylamines. The Provisional Specification refers to bisamidines similar to the above but in which all four nitrogen atoms bear a chlorobenzyl group, for example N,N,N1N1 - tetrakis(3,4 - dichlorobenzyl) sebacamidine which is prepared by treating N,N1 - bis(3,4 - dichlorobenzyl)sebacamide first with phosphorus pentachloride and then with 3,4-dichlorobenzylamine. N,N1-bis(3,4-Dichlorobenzyl)sebacamide is perpared by treatment of sebacyl chloride with 3,4-dichlorobenzylamin in the presence of pyridine.ALSO:Bacteriostatic compositions comprise a compound of general formula <FORM:0891939/VI/1> in which R is a substituted benzyl group containing one or two chlorine atoms, (A) is an alkylene group having from four to twelve carbon atoms, a phenylene, or a tolylene group, and X is an organic or inorganic anion, in association with a carrier. Preferred compositions are tablets for internal use, and ointments or salves for external use.  A convenient concentration of the active substance in a tablet is from 25 mg. to about 300 mg. per tablet, and for a salve or ointment 2 to 10% by weight. Other active constituents may be present.  A detailed example of a tablet is given.  The Provisional Specification also refers to compounds similar to the above but in which all four nitrogen atoms bear chlorobenzyl groups, e.g. N,N,N1,N1 - tetrakis(3,4 - dichlorobenzyl) sebacamidine, as active principles of bacteriostatic compositions.

Title: Railway Brake Safety Device
IPC: B61H13/24
Filed: 1968-08-27
Abstract: 1,191,765. Brake linkages. AMSTED INDUSTRIES Inc. 27 Aug., 1968 [15 Sept., 1967], No. 40882/68. Heading F2E. A railway brake rigging comprises a brake lever pivotally connected to a brake rod, the brake rod having an opening near the pivotal connection, there being means secured to the brake lever and slidably engaged in the opening for supporting the brake rod from the brake lever in the absence of the pivotal connection. The invention thus provides a safety device for a brake rod in case of mechanical failure of the pivotal connection. Preferably the brake rod is a brake compression rod. As shown, a brake rod 34 extends from actuating means and is pivotally connected at 32 to a brake lever 30 which in turn is pivotally connected by a pin 42 in one of several openings 40 in the bifurcated end 38 of a brake compression rod 36. The end 38 is extended upwards by side walls 43 and a top wall 45 to define an opening 44 in which is located, with clearance, the head of a bolt 46, Fig. 4, secured to the brake lever 30 above pin 42. If the pin 42 fails, the rod 36 drops until the top wall 45 engages the bolt 46 whereby it is retained. The bolt may be longer than as shown in Fig. 4, to permit a flanged tubular spacer to be located on the bolt between its head and the lever 30. The opening 44 may be provided, as an alternative, in a member which may be secured to an existing brake rod. The lever 30 is pivoted at 28 to a conventional brake beam 16 having a brake head 21 and shoe 23 for engagement with a railway car wheel 25.

Title: Die and method for drawing metal tubes
Inventor: MATTHEWS RAYMOND ARTHUR
IPC: B21C37/18
Filed: 1969-08-20
Abstract: 1,220,766. Drawing. R. A. MATTHEWS. 20 Aug., 1969 [19 Sept., 1968], No. 41494/69. Heading B3P. A die 17, Fig. 3, for drawing a tube on to a tapered mandrel is composed of a non-metallic plastic material capable of stretching radially and being contracted back to its original annular form. In one embodiment the smaller end of the tapered mandrel with a tube thereon is threaded through the die 17, e.g. of nylon, and fluid pressure from a line 41 is supplied through a die holder 37 and into a groove 33 in the die. The die land 29 is thereby contracted against the tube which is collapsed on to the mandrel. The tube is drawn through the die by an hydraulic cylinder and as the die orifice diameter is increased by the increasing mandrel diameter, the original land area 29 is buckled outwardly from the tube, Fig. 4, and the effective land progresses towards the entry end of the die. The backing pressure is maintained constant during drawing by draining fluid from the chamber 33 through a pressure relief valve (44), (Fig. 1, not shown). In another embodiment, the tube is drawn from a large to a small diameter by first drawing a tapered extension (49) (Fig. 9, not shown) of the mandrel through the die which is thereby expanded. After collapsing the tube onto the mandrel by supplying fluid pressure to the chamber 33, the drawing of the tube is initiated, the die being contracted progressively around the tube. Additional fluid is supplied to the chamber 33 through an accumulator (53) to compensate for the pressure loss due to the contracting die. The die may be strengthened by fingers (54) (Fig. 12, not shown) spring-urged into the groove 33.

Abstract: 1,122,987. Microwave heating. MICROWAVE INSTRUMENTS Ltd. 11 Oct., 1965 [12 Oct., 1964], No. 41497/64. Heading H5H. [Also in Divisions F4 and G1] Particulate material is heated or dried by the absorption of microwave energy while being passed down a vertical waveguide 1 in countercurrent to a heated pressurized air flow which maintains the material in a fluidized state. As shown in Fig. 3, microwaves from a generator 8 pass down the waveguide through the material and are mostly absorbed in a lossy load 30. A directional coupler 31 leads part of the microwave energy through a level set attenuator 33 to a crystal detector 34, the output of which controls the power output of the generator 8 or the temperature and/or humidity of the incoming air. Rejector means 14, 15 prevent leakage of microwave energy through openings 2 and 6. A vacuum extraction unit may be provided at the top of the waveguide to set up a forced circulation.

Abstract: 1450095 Fluid control circuits SIEMENS AG 5 Sept 1973 [23 Nov 1972] 41768/73 Heading Fl D [Also in Division F2] An actuator 7, 8, Fig. 1, clamps a workpiece to be welded between electrodes 11, 12 and when a predetermined pressure is reached a pressure sensitive switch 19 completes a circuit to provide a welding pulse. Compressed air is drawn from a compressor or cylinder 16 through an operating pressure valve 17 to a reversing valve 15 and through an adjustable throttle valve 18 to the switch 19 to provide a reference pressure at which the switch triggers. During the clamping cycle air passes to a chamber 6' through a throttle 21, switch 19 and check-valve 23. When a chamber 6 is being pressurized the chamber 6' is vented through a line 25 and check-valve 26. Air from the source 16 is fed to a chamber 37, Fig. 2, of switch 19 through a port 18', thus holding open a valve 40, 41 against the pressure of a spring 39. Air is supplied to the actuator chamber 6' through a port 20, chamber 36, valve 40, 41 and port 22. As pressure builds up in the chamber 6' pressure in the chamber 36 pushes a diaphragm 31 down against the reference pressure in chamber 37. This closes the valve 40, 41 and operates a switch 33 to provide the pulse of welding current. Hydraulic liquid may be used in the circuit.
