Title: Improvements in or in connection with the Manufacture of Hollow Glass Articles.
Inventor: ROIRANT EMILE
IPC: C03B9/193
Filed: 1916-08-01
Abstract: 108,352. Roirant, E. Aug. 1, 1916. Blowing.-In manufacturing " pressed blown " articles, a short parison which fills the parison mould and the superposed neck mould is drawn out mechanically to the requisite length for blow. ing in the finishing mould by moving the neck mould away from the parison mould or vice versa. A parison mould 1, Fig. 4, the cavity of which is approximately spherical, is almost filled with molten glass, and a pressure plunger 3, Fig. 5, is introduced and forces the glass to fill the neck mould 2. The parison mould is then moved away from the neck mould, as shown in Fig. 6, thus compelling the glass to pass through the orifice of the parison mould. The parison is thus drawn out to its proper length without exposing the glass to the chilling effect of large metal surfaces In some cases, the plunger may move downwards with the mould to assist the stretching process.

Title: Improvements in apparatus for trimming, turning and pressing collars and the like
Inventor: HUNT HARRY CLEVELAND
IPC: D06F71/22
Filed: 1959-03-31
Abstract: 863,594. Cutting-machines. AMERICAN SAFETY TABLE CO. Inc. March 31,1959, No. 10909/59. Class 31 (1). [Also in Group VII] In a collar-making machine (see Group VII) trimming of the collar edges is effected by cooperating trimming members 35, 40. The trimmer head 35 is mounted on a rod 55 for vertical reciprocating movement while the stationary trimmer block 40 is located on a shelf 34 in a U- section frame. The head has a V-shaped recess 36 and is undercut to provide divergent cutting edges 38. A compression spring 41 forces the complementary pointed end of the block 40 against the recessed head. In using the machine, a collar is fitted over a pointed member 44 pivoted to the frame at 43 and arranged to swing downwardly and hold the collar against the block while trimming takes place. Actuation of the trimming mechanism is effected by a double-acting pneumatic cylinder 72 controlled by a solenoid-operated valve 47. The rod 55 carrying the trimmer head is connected to the piston 50 by a pivoted link 52. The piston has also at its upper end a plate 56 through which is threaded a screw 64 registering with the lower end 57 of a rod 58 pivoted to the rocker arm 60 of the collar-carrying member 44. The rod 58 is biased downwardly by a compression spring 62. In the normal positions of the machine parts as in Fig. 17, the solenoid is deenergized and air under pressure from conduit 65 acts on the head 67 in the valve 48 thus moving the sliding rod 68 and associated valve element 69 to open the passage 71 leading to the lower end of the cylinder and to close the passage 70, 74 leading to the upper end of the cylinder. The piston 50 is forced upwardly causing the trimmer head to be held in its lowermost position and the collar-carrying member 44 to be raised against the action of the spring 62. When the solenoid is energized air flows through branch conduit 66 into valve 47 and exerts pressure on the head 75 so as to move the rod 68 in the reverse direction and open the passage 70. Air pressure at the upper end of the cylinder forces the piston head downwards to raise the trimmer head and lower the member 44. The machine comprises two such trimming mechanisms mounted side by side and operated from the same piston 50.

Title: Improvements in or relating to the preparation of titanium compounds
IPC: C01G23/00
Filed: 1931-04-14
Abstract: A basic titanium oxalate is obtained by precipitation from a mineral acid solution of tetravalent titanium under regulated conditions of neutralization, dilution, presence of oxalate radicle, and temperature.  For instance a solution of titanium sulphate may be treated with calcium carbonate, with or without separation of the calcium sulphate precipitated, until it contains 0,6-0,7 mols. of SO3 to each mol. of TiO2, dilution be effected until the solution contains 3 per cent weight by volume of TiO2, and precipitation be effected by addition of 0,15-0,3 mols. of oxalic acid per mol. TiO2. Precipitation is preferably carried out below 50 DEG  C. and may be effected in presence of an extender such as barium or calcium sulphate as by neutralizing with an alkaline-earth metal carbonate or precipitating with an alkaline-earth metal oxalate.  Solutions consisting largely or entirely of chloride need less neutralization, whilst the character of the precipitate may be favourably influenced by the presence of sodium chloride.  By leaving a small portion of the TiO2 in solution a purer product is precipitated.  The basic oxalate obtained at low temperatures is readily soluble in acids, and by treatment with alkali titanium hydroxide also readily soluble in acids may be produced.  The products obtained from the process may be dried and calcined to form pigments.

Abstract: 721,829. Guillotine cutting-machines. WALLIS, L. S. May 16, 1952 [May 17, 1951], No. 11511/51. Class 31(1). A power-operated guillotine has a blade 9 mounted pivotally at its ends, one of which is moved to its lowermost position during the shearing operation before the other is lowered. The blade 9 is guided at one end by a bracket 40 fixed to a beam 6 on which is supported a co-operating stationary blade adjustable by locking-screws 8. The blade 9 is secured by an angle-beam 10 to bearing-blocks 11, 12 by which it is pivotally-mounted on trunnions 24, 13 suspended on pins 25, 14 from levers 26, 17. A spring 37, Fig. 2, acting between the bifurcated end 33a, 33b of a link 33 pivoted on the pin 25, contacts a projection 36 on the block 11 to swing the blade 9 laterally, about the trunnions 24, 13, into engagement with the fixed blade 7. The rotation of the blade 9 is limited by a stop-screw 34, and the lateral pressure between the cutting edges, which effects sharpening of the blade 9 during the shearing operation, is adjustable by a screw 35. The blade 9 is mounted on the blocks 11, 12, by screws 39 engaging slots in the blocks so that the blade can be inclined in plan view relatively to the blade 7 to produce contact between the blades at a point only during the shearing operation. The latter is effected by lowering first the end of the blade 9 supported by the pin 25 and then that carried by the pin 14 by poweroperated means, e.g. the pneumatic cylinders 21, 30 of which the ram 29 for the cylinder 30 is operated before that for the cylinder 21 and has the longest stroke. As the point of contact between the blades travels along their length, the blade 9 rocks about the trunnions 24, 13 against the influence of the spring 37.
