Abstract: 914,740. Endless conveyers. BAKER PERKINS Ltd. Aug. 27, 1959 [Sept. 5, 1958], No. 28545/58. Class 78 (1). Articles are transferred from a feeding conveyer to a receiving conveyer at an angle thereto by means of a transfer conveyer, aligned with either the feeding conveyer or the receiving conveyer and supported on a frame which is pivotable about a horizontal axis so that raising or lowering of the transfer conveyer permits completion of the transfer of articles to the receiving conveyer. As shown, Fig. 1, strapped groups 1 of baking tins are transferred from a conveyer 2 to a conveyer 4, comprising spaced endless bands 11, 11<SP>1</SP>, by means of a transfer conveyer 5 which is aligned with the conveyer 2 and comprises endless chains 18, Fig. 2, mounted on a frame 17 pivoted at one end on a shaft 15 about an axis 13 and supported at the other end by means of an hydraulic or pneumatic ram 31, 32 or a solenoid device. Idler sprockets 22, 23, 24 deflect the upper runs of the chains 18 beneath the upper run of the band 11 by an amount sufficient to permit raising movement of the conveyer 5 about the axis 13 to carry an article thereon clear of the runs 11, 11<SP>1</SP>. In operation, an article passing from the conveyer 2 on to the conveyer 5, which is raised clear of the bands 11, 11<SP>1</SP>, actuates a switch means 35 to raise stops 7 to stop ensuing articles and, when positioned abreast both runs 11, 11<SP>1</SP>, actuates switch means 36 to lower the ram 31, 32, thereby being deposited on the runs 11, 11<SP>1</SP>. The articles are transferred from the conveyer 4 to a conveyer 3 by means of a similar transfer conveyer 6 aligned with the conveyer 3. The Specification describes how the invention can be applied to a bakery plant in which a stream of empty bread tins carried on one conveyer is divided into two conveyer lines by means of transfer conveyers of the type described above.

Abstract: 489,273. Forming staple fibre yarns or like products. POOL, W. Oct. 21, 1936, No. 28594. [Classes 120 (ii) and 120 (iii)] Staple fibre yarns or like products are formed by feeding a substantially twistless bundle of associated continuous filaments towards a rotating drum, separating the filaments of the bundle from each other at the end of the bundle, obtaining from the separated filaments a succession of groups of separated fibres of predetermined length by a cutting operation, nipping each group of cut fibres to the peripheral surface of a drum at a point which, by reason of the rotation of the drum, progresses along the length of the group and withdrawing the overlapping groups through a passage to the axis of the drum, the rates of feeding and withdrawal being such that the twist imparted by the drum unites them into a continuous twisted product. A number of nipping-points may be provided with corresponding passages leading to the axis of the drum, the several successions of groups being united and twisted together. The fibres may be of cellulose acetate or other organic derivatives of cellulose. Apparatus generally similar to that described in Specification 489,272 is shown, the groups severed from a bundle 13 being nipped by the co-operation of a covered roller 11 with a part 6 of the surface of the drum 1 and withdrawn through the passage 7. The filaments are separated from each other, fed and severed generally as described in Specification 489,272. Specification 484,192 also is referred to.

Abstract: 1,189,859. 8tacking bricks; endless conveyers. J. LINGL. 21 June, 1967 [21 June, 1966], No. 28750/67. Headings B8A and B8C. Bricks are stacked by forming two separate brick layers, inverting one layer and placing it upon the other so that the brick faces in contact will not be discoloured during subsequent firing, lifting the double-layer group and separating it into individual rows of double brick height and depositing the rows, e.g. on a kiln trolley, to form the base of a stack. The apparatus for stacking comprises a conveyer 1, carrying a continuous row 2 of bricks, and a reciprocating pusher device, Fig. 2 (not shown), for moving rows 3 and 4, of fixed length, alternately from conveyer 1 on to conveyers 5 and 6. A pusher 14 moves rows 4 from conveyer 6 on to an intermittently moving conveyer 21 until a first layer of three abutting rows is formed. A pusher 8 moves rows 3 from conveyer 5 on to a platform 49 until a second layer of three abutting rows is formed. The pushers 14 and 8 are actuated when the rows 4 and 3 abut respective end stops (60, Fig. 5). The second layer is then lifted, inverted and lowered on to the first layer by a gripper assembly 7, which rotates through 180 degrees about an axis 13. A gripper head 29 is lowered and picks up two adjacent groups 22, 23. The head 29 then separates the groups into rows running perpendicularly to the original rows 3, 4. The head 29 is substantially as described in Specification 1,002,288 and is mounted on rails 24, 26, for longitudinal and transverse movement, for setting down the separated rows in a convenient position on a kiln trolley 55 to form stacks 25. The head 29 may be rotated through 90 degrees so that the next batch of separated rows may be stacked at right angles to the first. Conveyer 5 and platform 49 may be higher than conveyers 6 and 21 by a distance equal to one brick height.

Patent GB-723397-A (GB)
Title: Production of hydantoin and of glycine
IPC: C07D233/72
Filed: 1952-11-17
Abstract: A process for making hydantoin comprises introducing one molecular proportion of formaldehyde into contact with an aqueous solution containing an ammonium carbonate and an alkali metal cyanide in proportions sufficient to provide the chemical equivalent of at least two mols. of ammonia, and at least 1.5 mols. of carbonate and at least one mol. of the alkali metal p  cyanide, maintained at a temperature of from -10 DEG  to 30 DEG  C., either by slowly adding the formaldehyde in the form of an aqueous solution at a rate such that not more than one mol. of the formaldehyde is released into contact with the dissolved salts in the solution over a period of 4 hours or more or by dissolving a proportionate amount of paraformaldehyde in the solution, then heating the solution at a temperature of from 50 DEG  to 120 DEG  C. to complete the reaction and form hydantoin.  Glycine is prepared by boiling the aqueous reaction liquid to distil ammonia and carbon dioxide, mixing the residual aqueous liquid with an alkali metal hydroxide in amount corresponding to at least two mols. of the alkali metal hydroxide per mol. of the formaldehyde starting material, heating the alkaline solution at a temperature between 130 DEG  and 250 DEG  C. under pressure to hydrolyse the hydantoin and recovering glycine from the alkaline hydrolysis liquid.  Starting materials mentioned include sodium or potassium cyanide and ammonium carbonate or bicarbonate. The alkaline solutions containing hydantoin and glycine are treated with cation exchange resins in hydrogen form to remove alkali metal ions before separating the desired products.  Insoluble sulphonated vinyl aromatic resins and sulphonated phenol-formaldehyde resins are mentioned.  In examples: hydantoin is obtained by dissolving paraformaldehyde in an aqueous solution containing sodium cyanide and ammonium bicarbonate, boiling the solution, treating it with decolourizing charcoal and a sulphonated vinyl aromatic resin in hydrogen form and concentrating and cooling the residual solution (1); reaction liquor from (1) is heated in an autoclave with sodium hydroxide and the solution is decolourized, boiled, cooled, treated with the ion exchange resin used in (1); concentrated and treated with methyl alcohol to obtain glycine (2); and formaldehyde is gradually added to an aqueous solution of ammonium carbonate and sodium cyanide, the mixture is heated under pressure, ammonia and carbon dioxide are boiled off, aqueous caustic soda is added and the solution is pumped through a heated tube to effect hydrolysis of the hydantoin.  The hydrolysed solution is treated with the ion exchange resin used in (1) and concentrated and glycine is precipitated by the addition of methyl alcohol.  Specifications 687,486 and 693,522 are referred to.  Reference has been directed by the Comptroller to Specifications 687,486 and 693,522.
