Title: Manufacture of crystallised arsenobenzenes
IPC: C07F9/74
Filed: 1926-10-04
Abstract: 259,245. Albert, A. Oct. 3, 1925, [Convention date]. Arsenobenzenes are produced in a crystalline form by treating trivalent or pentavalent organo arsenic compounds of the type As-Ar-CO-R (in which Ar represents a substituted or unsubstituted aryl residue and R represents alkyl or hydrogen) in solution or suspension with hypophosphorous acid or a salt thereof. The derivatives of the aforesaid arsenic compounds obtained by reaction with a hydrazine compounds may also be used as starting materials. When using pentavalent arsinic compounds it is advantageous to add small quantities of hydriodic acid or its salts. According to the examples, crystalline arsenobenzenes are obtained by adding (1) hypophosphorus acid and a little hydriodic acid to a solution of m-hydroxybenzaldehydearsinic acid semicarbazone hydrochloride or the corresponding arsinic acid chloride in alcohol, (2) m-hydroxyacetophenone-p-arsenoxide semicarbazone to a solution of ammonium hypophosphite in glacial acetic acid, (3) a solution of sodium hypophosphite in glacial acetic acid to a solution of pacetophenonearsenoxide in the same solvent, and (4) aqueous hypophosphorous acid containing a little hydriodic acid to an alcoholic solution of m-hydroxyacetophenone-p-arsinic acid semicarbazone hydrochloride. Specifications 199,091 and 199,093 are referred to. The Specification, as open to inspection under Sect. 91 (3) (a) also includes an example according to which p-hydroxy-m-acetylaminophenylarsinic acid is reduced to the arseno compound with sodium hypophosphite and a little potassium iodide in glacial acetic acid. This subject-matter does not appear in the Specification as accepted. m-Hydroxybenzaldehyde-p-arsinic acid semicarbazone and its chloride are prepared by arsenating m-nitro-p-aminobenzaldehyde according to Bart's method, reducing the nitro group to the amino group, replacing it by hydroxy, converting the product into its semicarbazone, and if desired evaporating a solution of the arsinic acid in alcoholic hydrochloric acid.

Filed: 1919-10-08
Abstract: 154,400. Williams, O. R. Oct. 8, 1919. Safety, fouling, and locking bars.-In locking- bars and other signalling-bars of the kind operated by a balance or rod on which two balance springs are used to assist in raising the bar, the bracket supporting the buckle and balancer is fixed to the track rail, so that, since the rockers supporting the bar are also carried by the rail, creeping of the rail does not cause relative movement of the bar and the bracket which would upset the adjustment of the balancing action. The bracket is formed of a bent piece of mild steel or iron flat bar A bolted to the track rail. Holes A<3>, B are bored in the upturned bracket side A<2> and in the opposite upturned side of a piece of angle iron B bolted to the base of the bracket A. The trunnions C of the balancer sleeve or buckle C<1> are supported in the holes A<3>, B Alternatively, a plain mild steel bracket or casting may be bolted to the rail and used to support the castings already employed for securing the balancer to sleepers. In a modification used for locking-bars which are raised and then returned to their original position instead of being raised to the top and then moved over to the opposite lower position, a mild steel, iron, or cast-iron bracket is bolted to the track rail. The balancer rod passes through a hole in a partly circular oscillating fulcrum block mounted in a partly circular recess in the bracket. Only one balance spring is required in this type. Alternatively, a bracket &c. as shown in Fig. 4 may be used for locking bars of this kind, the balancer rod being provided with only one balance spring.

Filed: 1974-06-05
Abstract: 1474735 Milking machines J M PERKINS and G A F CHILLINGWORTH 5 June 1974 24828/74 Heading AIM The pressure fall which occurs at the cessation of milk flow is used to actuate a device which terminates milking by closing the milk line of a milking machine. A housing 18 contains a diaphragm 19 having a central stem 41 which carries a rubber discoid valve member 42 and a U-cup seal 43 slidable within the bore 44. The milk line 24 is connected to an upper chamber of housing 18 by a conduit 21 leading from a T-piece 25 connected to a claw 23. A piston and cylinder assembly 35 comprises a vertical cylinder 36 housing a piston 37 coupled to the T-piece 25 by a flexible line 38. A conduit 40, connected to the top of cylinder 36, is in air flow communication with the upper chamber of housing 18 via an aperture 32, and may also be brought into air flow communication with the atmosphere via the valve member 42 or an aperture 54 through the housing 18. The aperture 54 can be closed by a suction cup 53 urged onto its seating by the plunger of a timer 49, and it can be manually opened by the use of handle 50. During the milking process, both the lower chamber below diaphragm 19 and the upper part of cylinder 36 are connected to atmosphere via aperture 32 and the open valve member 42. With aperture 54 closed, the pressure fall in the upper chamber of housing 18 at cessation of milk flow produces a differential pressure on diaphragm 19 which elevates valve stem 41 and closes valve member 42. As a result, the vacuum line 29 is connected to cylinder 36 via the aperture 32, and the T-piece 25 lifts and terminates milk flow by kinking a length of hose 22. In order to prevent premature termination of milking being brought about by a hiatus which may occur after an initial milking period, the aperture 54 is manually opened at the start of milking, and closed at the end of the hiatus after a time interval controlled by the timer 49. A secondary air bleed aperture (not shown) may also be included in the milk line conduit 21.

Abstract: 1,093,005. Woodworking. P. A. KIRSTEN. June 14, 1965 [June 13, 1964], No. 25124/65 Heading B5L. A machine for cutting wood chips has means for automatically changing the knives 4, 5 comprising a frame 8 having receiving stations 14 for units 41 ... 46 containing knives, the frame being movable relative to a carrier 1 for units 31 ... 36 for the knives 4, 5 so that the units 31 ... 36 may be moved from the carrier to the frame and the units 41 ... 46 from the frame to the carrier by mechanical, electromagnetic, pneumatic or hydraulic means. The carrier 1 is rotatable about a shaft 2 so that the knives comprising marking knives 4 and cutting knives 5 reduce a block of wood 7 supported by a guide 6 and pressed against the carrier into chips. The units 31 ... 36 are retained in the carrier 1 by locking rods 24, Fig. 2, urged resiliently outwards. The machine has a pair of guide rails 9 for the frame 8 which has a number of recesses 14 for carrying the units 41 ... 46 having sharpened knives. When the knives in the units 31 ... 36 have become blunt, the carrier is stopped and positioned with the unit 31 adjacent a magnetic plate 35 by a locking bar 11 actuated by a cylinder 13 engaging a recess 12 in the carrier. The frame 8 is positioned in the guide rails 9 with an empty recess 14 aligned with the unit 31. A cylinder 16 is then actuated to move the magnetic plate 15 which is energized so as to hold the unit and move it from the carrier to the recess 14 in the frame, the locking rod 24 having been moved by a rod 21 of a cylinder 20 to permit the movement of the unit. The magnetic plate is then de-energized and retracted and the frame moved by a motor 22 to align the unit 41 with the empty recess in the carrier. Thereafter, the magnetic plate is again advanced by the cylinder 16 and energized to hold the unit 41, the extension of the plate carrying the unit from the frame to the carrier where it is retained by the locking rod 24 after release by the cylinder 20. The carrier is then indexed to align the next unit 32 with the magnetic plate and the process repeated until the units 41 ... 46 have replaced the units 31 ... 36, the frame being removable from the guide rails so that the knives of the latter units can be sharpened while the machine is using the other knives. In another embodiment, the knives are carried on the inner cylindrical surface of a dish-shaped carrier and the wood to be reduced to chips is thrown against the knives by a rotating cross having a direction of rotation opposite to that of the carrier. The knives are secured to knife holders and, when blunt, are replaced by a second set which are mounted on an annular frame that can be mounted on an extension of the shaft of the rotary cross. A magnet carried by the rod of a cylinder is swung into operative position about a pivot and energized to effect the changing of the knife holders.
