Patent GB-940559-A (GB)
Title: Glass cutting apparatus
IPC: C03B33/03
Filed: 1961-02-15
Abstract: In apparatus for scoring parallel lines on a glass sheet by moving it on a conveyer under transversely spaced scoring devices, means for squaring the leading edge of the sheet on the conveyer initially comprise two transversely <PICT:0940559/C1/1> spaced stops, each incorporating means to detect when it is contacted by the leading edge of the sheet, the stops being moved out of the path of the sheet when both have been contacted by the leading edge.  Thus if the leading edge is not square it is retarded by the stop which it contacts first until movement of the conveyer brings the edge against the other stop also.  In the form shown the sheet is carried from left to right until its edge contacts stops 26 carried on a shaft 24. Each stop comprises a stop member 37 on an arm 34 pivoted to a bracket 33 and located between a stop-screw 44 and a stop-spring 41. Movement of the arm 34, when the glass strikes the member 37, operates a switch 1LS through an arm 42.  The switches of both stops are in a relay circuit which, when both are operated, opens a solenoid operated valve to feed air to a piston (not shown) which turns the shaft 24 to lift the stops away from the glass.  At the same time, movement of a projecting arm 49 lowers rollers 48 on to the glass to hold it in contact with the conveyer by their weight.  A switch closed by the leading edge of the glass maintains the stops out of contact with the glass until it has passed and also opens another solenoid-operated valve to feed air to cylinders which lower a beam to bring the scoring devices on to the glass.  These devices are mounted to be adjustable transversely of the glass and may be ultrasonically oscillated to open the cracks as they score.  After the sheet has passed the parts of the apparatus return to their former positions in readiness for the next sheet.

Abstract: 452,487. Tamping blasting-cartridges. SAFETY MINING CO., 307, North Michigan Avenue, Chicago, U.S.A. Feb. 23, 1935, No. 5872. Convention date, Feb. 28, 1934. [Class 9(i)] Relates to the tamping of blasting-cartridges which are charged with a fluid under pressure while in the borehole, and consists mainly in the provision of means adapted to be expanded by the fluid pressure during the charging of the cartridge to engage the borehole to produce an effective tamping. As shown, the device comprises a number of rubber rings 32 adapted to be pressed up on cones 31 by rings 35 operated by a number of rods 75 by the head 40 of a plunger 18 subjected to the fluid pressure. The pressure fluid is supplied to the cartridge 4 by a pipe 42. When a certain pressure has been reached the fluid passes through a non- return valve 26 and by its pressure on the flange 22 of the plunger 18 drives this plunger inwards, and thereby the rings 32 are wedged up and expanded into firm gripping contact with the borehole.

Title: Improved process for preparing and for purifying octachlorodihydroxydiphenyl
IPC: C07C37/86
Filed: 1962-02-16
Abstract: Octachlorodihydroxydiphenyl is made by hydrolysing powdered decachlorodiphenyl with an aqueous solution of alkaline hydroxide or alkaline earth hydroxides in the absence of organic solvents at a temperature in excess of 200 DEG  C., and precipitating the octachlorodihydroxydiphenyl thus formed by acidification of the reactants.  The hydrolysis is preferably carried out between 240 DEG and 250 DEG  C. Powdered decachlorodiphenyl of 20 to 40 microns as described in Specification 897,149 may be used.  If still finer powder is used, the addition of a wetting agent is advisable, e.g. sodium methyloleyltauride or monolaurate of polyethyleneglycol. The crude octachlorodihydroxydiphenyl may be purified by the alkaline aqueous solution of impure product with a salt of a heavy metal or alkaline earth metal, e.g. a salt of iron, copper, manganese, calcium, barium, strontium or magnesium, then separating the metal hydroxide formed and precipitating by acidification, e.g. with a mineral acid, such as sulphuric or hydrochloric, and draining, washing and drying the purified octachlorodihydroxydiphenyl.

Class 64 (3). In order to prevent the formation of ice at the outlet ends of air-cooled surface condenser elements 1, 2 arranged in V-formation as shown, some of the cooling air which has been drawn by main fans 14 over the relatively warm upper ends of the elements is, at predetermined low temperatures of either ambient air or condensate, directed by auxiliary fans 17 over the relatively cool lower ends of the elements. The auxiliary fans are arranged in flanged apertures 19 in a plate member provided also with other apertures covered by hinged flaps 21, 22. At normal and higher ambient air temperatures these flaps are open to the position shown by the dotted lines in the Figure, and the auxiliary fans are stopped. On a fall in temperature of either the condensate or the cooling air, a thermallysensitive device (not shown) causes the flaps 21, 22 to close and at the same time switches on the auxiliary fans 17 and reduces the speed of the main fans 14.

Classes 17 (1) and 17 (2). An outsole 4 is joined to a lasted upper 2 and insole 3 by a method comprising introducing a rubber mix 5 into a recess formed in the upper and insole assembly by the last 1 having a continuous lip around and projecting from its bottom face, pressing the upper along a line defined by the lip into direct fluid-tight contact with the outsole 4 and vulcanizing the mix 5. The upper and insole assembly is slip lasted. The outsole blank 4 is placed on a plate 6 which may have a contoured surface to contour the sole, and the rubber mix 5 is then superimposed on the sole blank. The lasted assembly is pressed down towards the outsole blank 4, the plate 6 possessing means for centralizing the lasted assembly with respect to the outsole blank, until the lower margin of the lasted unit seals down on the outsole blank. The rubber mix is then vulcanized by heating the assembly preferably using a heated last, the rubber mix thus forming the bond between the upper and insole unit and the outsole in the finished shoe. Means for centralizing the lasted assembly with respect to the outsole blank include a plate having a raised, shaped and contoured platform, a plate having a shaped and contoured recess in the form of a sole and heel and also a plate having blocks to engage with the toe and heel portions of the shoe. The rubbery mix may be superimposed over the margin only of the top face of the outsole with the central area being covered by a conventional filler, e.g. felt.

[Class 112] Relates to a double-loop sewing-machine having needle and upper foot feeds co-operating with a feed dog and a looper oscillating in the plane of the feed as described also in Specifications 536,792, 537,161 and 539,249. Oil splashed in chamber 13 by a ring 246 is collected in a reservoir 250 and delivered by a pipe 251 to the mechanisms in the bracket arm. Some passes to wicks 256 in a block 252 from which oil drips on to exposed mid portions of wicks in the hollow stems of the upper feed pitmans. These wick feeds are regulated by screws in the block 252 which compress the wicks 256. Oil is also led to a vertical bore in the partition 23 and the bearing bush 25 and lubricates the shaft 26. It also passes by a horizontal duct 264 to the end of the bush 25 and drips into an undercut recess in the end of the needle crank 70. A bore 268 in this crank leads the oil to the hollow crank pin 69 and to the hollow pitman 68. Oil passing to. the shaft 26 is limited by invariable grooves in a piston valve 279 in the vertical bore and that passing to the needle crank goes by way of another groove in the piston valve and its quantity is adjusted by turning the piston valve. The oil passing to the pitman 68 is controlled by the axial adjustment of a head 283 of a rod screwed at 272 in the crank pin. Oil is also caught by recesses in a plate 286, Fig. 20, in the lower part of the machine which deliver the oil to reservoirs 289, 290 and from these reservoirs the oil is passed to the bearings and the hollow members of the mechanisms below the work-plate by oil pipes and wicks.
