Abstract: 903,730. Pleating-machines. DAMAGNEY, D. Sept. 30, 1958 [Nov. 30, 1957], No. 31196/58. Class 141. A device is provided on a pleating-machine having pleating knives 4, 5 connected to reciprocating means, for altering the pleating depth of the machine in some predetermined sequence. In the arrangement shown, the essential components of a known pleating-machine are shown in dot-dash lines as comprising main drive-shaft 1, rollers 2, 3; blades 4, 5; blade-carriers 6, 7 and a blade carrier block 8 actuated by a lever 9 oscillated about pivot 9c by roller 10 riding in cam-way 11a The pivot 9c is carried by an adjusting lever 12 pivoted to the machine frame at 12a so that the position of the pivot 9c and thereby the depth of the pleat can be varied in operation. For this purpose a link 20 is adjustably secured to lever 12 at one end and to a crank 21 at the other. The crank 21 is secured on a secondary shaft 17 driven from the main shaft 1 through a pawl and dog arrangement which rotates the shaft 17 in semi-revolutions, thereby displacing the pivot bolt 23 from a position on one side of the line x-y to a position on the other side of line x-y and hence altering the position of pivot 9c and the depth of the pleat. The pawl and dog device can be controlled by a mechanism such as a pin-wheel and a rocking fork arrangement to control the frequency of the adjustment in accordance with a predetermined law.

A beam-steering apparatus is provided in a generally field-free region between the ends of a particle accelerator and comprises a pair of conducting plates 39, 40 flanking the beam trajectory. A resistive path connects the ends of the accelerator, and the plates 39, 40 are connected to points thereon in the electrical vicinity of the field-free region, one of the connections being adjustable to control the potential difference between the plates. As shown, one plate 39 is connected to conductive cylinder 115 and to the mid-point of a potentiometer 37 connecting the adjacent accelerator electrodes 26. The other plate 40 is connected to a potentiometer contact 42 secured to a nut 44 mounted on screw-threaded bolt 46 and prevented from rotating by bar 45. Movement of contact 42 is effected by rotation of insulating rod 50, which may be controlled by an earthed selsyn motor. After initial adjustment; correct beam-centring is automatic despite changes in the accelerating voltage or in the type of particle being accelerated. A second pair of deflecting plates 51 may be provided to effect beam-steering in a perpendicular plane. The apparatus is particularly useful in inclined-field accelerator tubes of the kind disclosed in Specification 1,006,063, but may be used in other accelerators for accurately directing the beam on to a target area.

[Class 8 (ii).] Apparatus for liquefying air as described in Specification 336,798, [Class 8 (ii), Air and gases, Treating &c.], is combined with a double column rectifier, e.g. as described in Specification 26720/08, [Class 8, Air and gases, Compressing &c.], so that the air leaving the liquefier at high pressure is delivered to the lower column 10 after reduction of its pressure and if required after condensation in a coil 11 used to heat the oxygen at the base of the lower column, while the other portion of the air leaving the expansion motor 5 is delivered to the upper rectifying column 12. Air is supplied to the lower column by a compresser 14, and liquid nitrogen from the lower column is delivered to the upper column where it rectifies the gas from the expander. If the supply of liquid nitrogen is greater than required for this purpose, air may be delivered at low pressure to the upper column by a compressor 15. The apparatus shown delivers oxygen in gaseous form from the upper column. If the oxygen is to be withdrawn as liquid, the gas from the expander is passed through a coil cooled by the escaping nitrogen before delivery to the upper column.

Abstract: 471,089. Theodolites. COOKE, TROUGHTON, & SIMMS, Ltd., and TAYLOR, E. W. Nov. 19, 1936, No. 31747. [Class 97 (ii)] A theodolite comprises means whereby an image of part of the circle is superimposed on a graticule carrying a number of parallel supplementary scales offset from each other by a distance equal to one scale division divided by the number of supplementary scales employed. Fig. 1 shows the principle of the invention and shows three supplementary scales A, B, C, Each scale is divided into minutes, and scales B and C are spaced longitudinally relatively to scale A by 20" and 40" respectively. Thus, when the reference line is at DD, the reading is between 1, 20" and 1, 40", and may be taken as 1, 30" with a maximlun error of + 10". Other examples show the use of a larger number of supplementary scales giving a less maximum possible error. In the theodolite, Fig. 5, a transparent horizontal circle 4 is illuminated by light passing from a mirror 5 through a prism 6, and is viewed in a telescope 16 through a light path 9, 10, 11, 13, 14. The circle is marked in degrees and three supplementary scales similar to those of Fig. 1, are marked on the member 11, to co-operate with the degree markings. The markings on the vertical circle 17 co-operate with supplementary scales mounted in a tube 24, the reading being viewed in a telescope 23.

Title: Improvements in the cooking of meats, vegetables and other substances which are normally cooked with common salt
IPC: A23L5/10
Filed: 1937-11-18
Abstract: 507,904. Cooking and preserving foodstuffs; table salt preparations. CHEMTEX, Ltd. Nov. 18, 1937, No. 31791. Convention 'date, June 16. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 20, 1938.] [Class 49] In cooking meat, vegetables, cereals,. and other foodstuffs normally cooked with common salt, a preparation is employed applied directly to the foodstuff or dissolved in its cooking liquor, consisting substantially of common salt and containing 4-10 per cent by weight of sodium or potassium orthophosphate or a mixture thereof, the preparation being in solution alkaline to methyl orange. The cooking processes which may be employed include boiling, steaming, baking, grilling and frying. With meat, improved results are obtained by applying the preparation some time before the cooking. Soluble sulphates and/or bicarbonates may be included, e.g. 1-25 per cent by weight of anhydrous sodium sulphate or 1-10 per cent of sodium bicarbonate. In an example, the preparation contains 7 per cent by weight of sodium orthophosphate, 5 per cent of sodium bicarbonate, 10 per cent of sodium sulphate and 78 per cent of common salt. Where chemically pure sodium orthophosphate is used it may be mixed with a small amount, e.g. 0À6 per cent by weight, of sodium carbonate. The salts used are preferably anhydrous, and are non-toxic or employed in non-toxic amounts. Chemical equivalents of the salts may be employed, e.g. sodium orthophosphate may be replaced by the mono- or disodium salt, the preparation being adjusted to the alkaline side by varying the proportion of bicarbonates. The alkalinity of the preparation may be such that 1À4-1À6 c.cs. of normal acid are required to neutralize a gram of it, using methyl orange as indicator. The preparation may be used in a concentration of 1-1À5 gm. in 100 c.cs. of water. The preparation shortens the time of cooking, makes the food more tender and, in the case of vegetables, preserves the colour. The Specification as open to inspection under Sect. 91 comprises also the treatment of organic materials such as foodstuffs with a preparation containing common salt and a water-soluble salt of one of the trivalent acids of phosphorus, or chemical equivalents thereof, in which may also be included soluble sulphates and/or carbonates and/or bicarbonates. The preparation may also be used as a substitute for table salt. This subject-matter does not appear in the Specification as accepted.
