Title: Improvements in brick making machines
IPC: B28B7/24
Filed: 1920-02-02
Abstract: 162,105. Cook, W. G. Feb. 2, 1920. Moulds.-Consists in a machine for moulding bricks, blocks, &c. having a mould-box a slotted at c to receive partition plates D which are so mounted as to be capable of horizontal reciprocation within the slots to free them from adhering material and to give a smooth finish to the bricks, and capable of being swung clear of the mould to allow the bricks to be pushed up out of the mould. In the form shown, the partition plates are connected by a rod g having operating-handles h, and are slotted at e to receive a hinge-rod d secured to the rear side of the mould. The slots e permit reciprocation of the plates when these are turned down into their operative position in the slots c.

Title: Carbamate esters
Inventor: JOHNSTON HOWARD
IPC: A01N47/18
Filed: 1966-01-24
Abstract: The invention comprises carbamate esters of the formula <FORM:1081806/C2/1> where R is a C1- 18 alkyl group and n is an integer of 1-4.  The compounds are made by reacting a chloropyridinol of the formula <FORM:1081806/C2/2> with an isocyanate RNCO, preferably in the presence of an inert solvent and a tertiary amine catalyst, e.g., triethylamine, trimethylamine and pyridine.  Suitable reaction temperatures are in the range 20-40 DEG  C.  The compounds possess antimicrobial activity (see Division A5). Numerous examples, many relating to the polychlorinated compounds, are provided.ALSO:Carbamate esters of the formula (I) <FORM:1081806/A5-A6/1> where R is a C1-18 alkyl group and n is an integer from 1-4, possess antimicrobial activity and are particularly useful as preservatives for paint and latex compositions.  The polychlorinated compounds are the most active compounds.  The antimicrobial properties of agar containing 0.05% of 3,5,6-trichloro-2-pyridyl methylcarbamate and 2,3,5,6-tetrachloro - 4 - pyridyl methyl carbamate are described.  The invention also includes pharmaceutical compositions comprising one of the above carbamate esters and a carrier or diluent which find particular use as anthelmintics.

Filed: 1942-03-16
Abstract: 558,133. Drawing; rolling. SIMONS, A. March 16, 1942, No. 3444. [Class 83 (iv)] The thickness of a work strip &c. is reduced by drawing it through rolls 22 supported throughout their length by rolls 25 which are reciprocated axially to reduce friction. The work strip A, Fig. 3, is drawn by one of the drums 20, 24, driven by a reversable electric motor between the rolls 22 supported and rotated, at a surface speed less than that of the strip, by the rolls 25 which are driven, through gears 31, Fig. 3, spline shafts 30, and gear 35, by a motor 38. Chain gearing 57 drives a shaft 49 which, acting through a double clutch 50, Fig. 5, and bevel gearing 48 rotates a pinion 45, Fig. 2, in engagement with racks 44 attached to two frames 39 ... 41 and 139 ... 141 in which the rolls 22, 23 are mounted. The axial movement of the rolls thus produced is reversed by pins 55 in the upper rack 44 which engage a lever 54 on a shaft 53 which carries a lever 52, Fig. 5, arranged to operate the clutch lever 51. The rolls 25 and frame members 41, 141 are mounted, to slide axially in cylinders 26, Fig. 2, which can be rocked simultaneously in opposite directions, to adjust the pass, by wheels 60, worm 61 and a hand-wheel 67, Fig. 6. The worm-shaft 62 is arranged to slide axially through a distance limited by adjustable nuts 64, 66 so that, after setting, the pass can be opened, to admit the work, by moving the shaft 62 axially, by means of the wheel 67 or of a lever 65, in a direction opposite to the proposed movement of the work, this work-movement causing the cylinders 26 to rock back to the present position.

Title: Production of marine propellers
IPC: B23P15/02
Filed: 1975-01-27
Abstract: 1462607 Making propellers; working at specified temperatures PRINCE EDWARD ISLAND MARKET DEVELOPMENT CORP 27 Jan 1975 [25 Jan 1974] 3452/75 Headings B3A and B3V A marine propeller is made by casting a propeller blank, bringing the casting to a workable temperature, applying a required pitch to the blades, and cooling the propeller to room temperature. Thus different moulds are not required for different blade pitches. The casting may be brought to a workable temperature either by cooling directly after casting, or by cooling the casting to room temperature, storing the casting, and reheating it when required to room temperature. The material may be a zinc-aluminium alloy having a melting point about 810‹ F., casting taking place at 880‹ to 925‹ F. To apply the required pitch, the blank may be heated to 600‹ F. and struck with metal or neoprene pads, or heated to 780‹ to 800‹ F. and subjected to static pressure. The propeller is then machined or polished to obtain proper balance, anodized, and coated with an epoxy paint, and the balance checked.

From the bottom outlet of the furnace IV, FeO and CaO are entrained by reducing gases from a nozzle 27 connected to the gas outlet of an upstream furnace II and fed to furnace III where sponge iron is formed. The sponge iron passes through a discharge pipe 16 to be entrained by a jet of town gas under pressure from a nozzle 12 and fed to a melting furnace I. The temperature of the effluent gases from the melting furnace is reduced and their reducing power increased by feeding carbon from hopper 22 to furnace II. Steam may be fed to furnace II to reduce the temperature of gas supplied to furnace III so that the sponge iron does not agglomerate. Carbon residues from furnace II are fed to the melting furnaces by a jet of hot air from a nozzle 7, and additional carbon from a hopper 38 may be supplied.
