Title: Improvements in machines for the production of hollow glassware
IPC: C03B9/22
Filed: 1933-03-27
Abstract: 421,562. Glass manufacture. LAWSON, A., and RANKIN AUTOMATIC GLASS FEEDER CO., Ltd., Fishergate, York. March 27, 1933, No. 9178. [Class 56] Relates to a glass-blowing machine of the kind in which a ring mould is moved vertically and is also swung about a vertical axis in order to transfer parisons from a parison mould to a finishing mould that is situated closer to the centre of the machine. According to the invention, the ring mould is moved vertically by an air cylinder, and the swinging movement is effected by the piston of an air cylinder which may be annular in shape. The machine comprises a number of mould units mounted on a table 1, Fig. 1, which rotates continuously about a vertical column 8. Each mould unit comprises a parison mould 18, a finishing mould 3, and a transferring- device. The finishing mould is situated between the parison mould and the column 8, and in such a position that it passes the forehearth or trough 28 into which the parison mould dips to gather charges of molten glass. The finishing mould is opened and closed by an air cylinder 5, and a blowhead 9 is swung on to, and away from, the mould by an air cylinder. The parison mould of each unit is supported on a carriage 27 which is raised and lowered by a lever 29 rocked by a cam 32 on the column 8. The position of the carriage can be adjusted vertically by a nut 35 in order to allow parison moulds of different lengths to be used in each mould unit, and to adjust the position of the mould to suit the level of the glass in the trough 28. The parison mould is opened and closed by an air cylinder 42 operated by an adjustable cam 44 secured to the column 8. The carriage 27 also carries a blowhead 45 which includes an air cylinder 47 for operating the neck-forming plunger. A transfer cylinder 49 is bolted to the blowhead casting 45, and its piston rod 50 carries at its lower end a plate 19 on which the ring mould 17, and an air cylinder 52 for operating it, are mounted. The piston rod 50 has an extension 59 which slides through and rotates with a spur wheel 60 that is engaged by a rack formed integrally with the piston 62 of an air cylinder 61. In a modified construction, a piston 67, Fig. 5, carried by a plate which is splined on the rod 59, slides in a cylinder 65 of semi-circular shape. In each case, movement of the piston 62 or 67 rotates the rod 50 through 180‹ and carries the ring mould from the position shown to a position in line with the finishing mould. At the same time, the rod 50 is lowered by the cylinder 49, thus transferring a parison from the parison mould to the finishing mould. The transferring mechanism can also be used with a non-rotary machine in which a single mould unit is mounted on a stationary bed plate, and the column 8 is replaced by a rotary shaft which carries the operating cams and the valves for distributing compressed air for the different operations.

Title: Improvements in or relating to machines for moulding tiles and the like
IPC: B28B3/02
Filed: 1931-03-26
Abstract: 369,006. Moulding tiles &c. SHARPLES, A. G., Glenfarg, Storeton Lane, Barnston, Wirral, Cheshire. March 26, 1931, -No. 9196. [Class 87 (ii).] In machines for moulding tiles and the like, the nail-holes are punched in the tile as the die commences its upward stroke immediately after the moulding-pressure has been relieved. The punches H are housed normally in the upper die B, but are depressed against the action of the springs h<2> by the cam G acting through linkage F, R, P. An adjustable bar f<2> limits the upward swing of the lever F and thus limits the down stroke of the punches. The up stroke of the punches is limited by an adjustable cross-bar q<2>, Fig. 3, which limits the swing of the lever P. The upper die is lowered in known manner by toggle-mechanism K indicated in outline only. The punching-operation also prevents the tile sticking to the upper die. In cases where the tiles are re-pressed the perforating takes place immediately after the second pressing operation.

Patent GB-572602-A (GB)
Title: Production of methyl pentadienes
IPC: C07C11/12
Filed: 1943-06-15
Abstract: Methyl pentadiene is produced by condensing acetone with a condensing agent to diacetone alcohol, catalytically hydrogenating this to diacetone glycol, and treating the latter in the liquid phase at a temperature below its normal boiling point with iodine or hydrogen chloride to dehydrate it.  The acetone may be condensed with alkali carbonate, bicarbonate, acetate, cyanide or hydroxide or alcoholates, or may be passed upwards through a cooled bed of granular soda lime or lime with a binder.  Diacetone alcohol may be separated by distillation and is hydrogenated, preferably in liquid phase at a temperature below its boiling point, e.g. 50-125 DEG  C.  Raney nickel is the preferred catalyst, but other base metals or oxides or mixtures or alloys thereof or noble metals may be used.  Carriers, and promoters, particularly high melting and difficulty reducible oxides and oxygen-containing salts, may be present.  Solvents such as alcohols, ethers, glycols and glycerols may also be used.  After removal of catalyst, the diacetone alcohol is separated and dehydrated with iodine, either alone or with, for example, hydrogen iodide or a salt thereof with a weak alkali such as aniline, or with hydrogen chloride, for example, as a concentrated aqueous solution. Generally about .02 to .5 g. of iodine per mol. of diacetone glycol is used.  An ordinary distillation kettle and column may be employed, the distillate being allowed to stratify and the methyl pentadiene recovered from the non-aqueous layer.  In examples: (1) a reactor containing bonded soda lime is continuously flooded with acetone, products withdrawn at the top being fractionated to separate diacetone alcohol which is mixed with Raney nickel and treated with hydrogen at 500 lbs./sq. in. and about 70-80 DEG  C. to give the glycol which is heated with iodine to 120-130 DEG  C., additional reactants being added periodically, the distillate being separated into phases, the water phase being removed and part of the anhydrous phase refluxed, methyl pentadiene being finally separated therefrom; (2) the dehydration is effected with iodine and 50 per cent aqueous hydrogen iodide at about 125 DEG  C.; (3) dehydration is effected with 38 per cent aqueous hydrogen chloride at about 140-145 DEG  C. The Specification as open to inspection under Sect. 91 (4) comprises the production of polyolefins generally by condensing aldehydes or ketones or mixtures thereof to give hydroxylated carbonyl compounds, hydrogenating to polyhydroxy compounds, and then dehydrating.  The initial materials may contain carbonyl groups attached to an alkyl chain, which may be linked to an aromatic, alicyclic or heterocyclic radical, or may comprise part of an alicyclic or heterocyclic structure.  They may be saturated or unsaturated and may contain substituent elements.  Various aliphatic aldehydes and ketones are specified.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the analysis of specimens by electromagnetic radiation
Inventor: FRANKS ALBERT
IPC: G01N23/207
Filed: 1958-03-26
Abstract: 908,182. Determining composition by radiation. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 25, 1959 [March 26, 1958], No. 9699/58. Class 40 (3). In order to determine the composition of a sample which is capable of emitting a characteristic radiation when suitably irradiated it is proposed to obtain the characteristic radiation and direct it to a reflector whose refractive index is less than that of the surrounding medium so as to investigate the critical glancing angle. X-rays, particularly longer X-rays, from substances of relatively atomic weight may comprise the characteristic radiation and the reflector may be angularly adjustable to determine the critical angle. The reflector adjustment, where adjustment is provided, may be calibrated in terms of wavelength or sample composition. In one embodiment a vacuum-tight casing, capable of being evacuated by a diffusion pump contains an electron gun, provision for mounting a sample as target or anode, a collimator for rays from the sample, an adjustable reflector, and a detector. The positioning of the reflector is controlled from outside the casing by a micro-meter screw and the point of adjustment corresponding a sudden change in the response of the detector to energy directed by the collimator on to the reflector and thence to the detector indicates the critical angle. The detector may comprise an electron multiplier and an external indicator. The sharpness of the change can be increased by using material of low density such as beryllium for the reflector. Diaphragms are used to prevent stray radiation reaching the detector. The electron beam from the gun may be concentrated on a small area of the sample by an electron optical system and the sample may be moved relative to the beam to obtain a point by point indication of its composition. When it is desired to check the composition of the end-product of a metallurgical process samples may be taken and irradiated with X-rays, the wavelength of the emitted characteristic radiation being measured as described above. Where this arrangement is employed the samples need not be placed in an evacuated casing but when very long wavelength energy is produced an atmosphere of hydrogen or helium may be required to avoid excessive absorption. In a control arrangement to maintain samples within given limits of composition two mirrors M1, M2 are fixed at angles to the common X-ray beam emitted by a sample which are, respectively, just greater and just less than the critical angle. The outputs of associated detectors D1 and D2 are fed to a difference circuit and any difference signal amplified and used to control regulator V to adjust the feed to the process producing the samples in such a way as to maintain the required limits of composition.

Title: Improvements in record changers for gramophones
IPC: G11B17/02
Filed: 1943-06-18
Abstract: 569,141. Automatic gramophones. AGA-BALTIC AKTIEBOLAG. June 18, 1943, No. 9824. Convention date, Oct. 2, 1942. [Class 40 (ii)] In automatic gramophones in which the automatic record changing operations are performed by one rotation of a cam wheel 12 adapted to be driven for that period by a friction pinion 11 on the turntable spindle 10, the engagement between the cam wheel 12 and the pinion 11 is brought about by a lateral displacement of the cam wheel. For this purpose, the cam wheel pivot 13 is carried by a lever 14 pivoted at 15 and guided at its other end by a pin 17 in a slot 18; and a cam disc 24 is fastened to the cam wheel 12 and formed with a saw-shaped notch 25 normally held in engagement with a pin 27 on a fixed bracket 28 by means of a spring 29 extending between the fixed bracket and the lever 14. The automatic cycle is started by imparting a slight counterclockwise rotation to the cam wheel 12 by means of a lever 30 acting on a pin 32 on the cam wheel. This wedges the notch 25 from the pin 27, causing the cam wheel to be shifted to the right to grip the pinion 10. After one revolution of the cam wheel, the notch 25 re-engages the pin 27. When it is desired that the camwheel should be capable of stopping in an intermediate position, as may be required when the supply of records is exhausted, a second notch 26 and a second impulse lever 31 are provided. Instead of starting the operation by an initial rotation of the cam wheel, the same result may be attained by a counterclockwise deflection of the lever 14. The mechanism may otherwise be as described in Specification 568,663.
