Abstract: 982,804. Ventilation; air heaters. AEROFLOW DYNAMICS Inc. Aug. 3, 1962, No. 29999/62. Headings F4S and F4V. An air or other gas supply unit, particularly an air heating and ventilating unit comprises a casing 11 through which air is blown by a fan (not shown) and is divided into two sets of internal passages 56, 57 separated by horizontal partitions (Fig. 5 being a sectional view turned to the vertical position), winged dampers 64, 65 mounted pivotally at the front edge of the partitions controlling the proportions of the gas flow through the two passages. As shown, alternate passages 57 contain transversely disposed hairpin type steam heating elements 81 which extend from inlet and outlet steam headers at the side of the casing. Each damper includes two curved wings one of which extends into a heating passage 57 and one into an unheated or by-pass passage 56. Single-wing dampers 68, 69 are disposed at the outer edges of the two extreme side passages. Adjacent dampers 64, 65 are arranged to rotate in opposite directions so that restriction of the air flow through one set of passages is accompanied by simultaneous increase in airflow through the other set of passages the convexly-curved form of the damper wings resulting in uniformly low resistance to airflow through the unit at all positions of the dampers. The heating passages 57 are slightly wider than passages 56 to compensate for the presence of the heating elements and the corresponding damper wings are longer than those in the by-pass passages. A motor 101 mounted externally to the casing operates through a mechanical linkage to adjust the positions of the dampers in dependence upon the temperature of the blended air streams as measured by a thermostat control (not shown). The linkage mechanism is arranged so that upon complete closure of the heating passages a switch 131 is closed to operate a second motor 132 which operating through a further system of links closes a set of dampers 90 at the exhaust end of the heating passages. The dampers 90 serve to prevent hot air leaking into the air flowing from the by-pass passages when the heating passages are intended to be completely shut off.

Patent GB-660817-A (GB)
Title: Improvements in the resolution of dl-methionine
IPC: C12P13/12
Filed: 1948-11-24
Abstract: A process for removing d-methionine esters from dl-methionine esters comprises allowing a preparation of pancreas ferments containing proteinase to act in the presence of water upon an ester of dl-methionine with a monohydric alcohol having 1 to 5 carbon atoms, and separating the substantially unchanged d-methionine ester from the l-methionine and any peptide-like compounds which have been formed from l-methionine as a result of the action of the pancreas ferments.  Pancreatin preparations, such as are used as leather bates, resolve the dl-ester into a mixture of d-methionine ester and free l-methionine.  Other pancreas enzymes, e.g. containing chymotrypsin, yield in addition compounds built up from l-methionine in the form of peptides.  The d-methionine ester and the l-methionine peptide, after separation, are hydrolysed to yield the d- and l-methionine respectively.  The ferment preparation can be employed either as such, or aqueous filtered or dialysed extracts, their lyophilic dried residues, or re-precipitated products may be used. From the reaction mixture the d-methionine is extracted with solvents, the free l-methionine is dissolved out in water, and the insoluble peptide compounds of l-methionine, if any, are filtered off and hydrolysed with acid to l-methionine.  Final purification may be effected by converting the isomers to their salts, e.g. with aromatic sulphonic acids.  Examples describe the action on dl-methionine isopropyl ester using of the ferment (1) and (2) the basic material for leather bates; (3) an ice-water extract of trypsin; (4) an ice-water extract of pangestin; (5) the dried pulverulent precipitate obtained by saturating the ferment of (1) with ammonium sulphate; (6) a product obtained by dialysing pancreas ferment in aqueous suspension, filtering off insoluble p  particles from the dialysed material, and drying the filtrate; (7), (8) and (9) crystalline chymotrypsin containing 50 per cent magnesium sulphate.  The products are worked up to give separate d- and l-methionine by the above general methods.  Samples have been furnished under Sect. 2 (5) of l-methionine and d-methionine obtained by resolving the (1) and (2) methyl ester, and (3) and (4) the isoamyl ester of dl-methionine, using the ferment of example (6).  The Specification as open to inspection under Sect. 91 comprises also the use of the benzyl and cyclohexyl esters of dl-methionine as starting material.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the selective handling of metal bars or billets
IPC: B21B39/00
Filed: 1928-10-22
Abstract: 305,449. White, A. E., (Morgan Construction Co.). Oct. 22, 1928. Rolling; roller tables.-Relates to cooling-beds for rolling plants and to like devices and consists in means for selectively removing the bars, &c. from the beds to the discharge devices either singly or in batches of number variable as desired, e.g., to select bars to be discarded. Bars arriving over a roller table 1 from shears (not shown) are stacked by skew rollers 5 and an end stop 6 against a pusher 7. This stack is then either transferred by the pusher on to the bars 11 of a cooling- bed 3 or the stop 6 is removed and the batch is forwarded to a stop 9 for transfer by a pusher 10 on to a second bed 4. The pushers are operated, in known manner, by ropes 12 attached to opposite sides of the pushers and passing over pulleys 13, 15 and making one or more turns round drums 14 driven by reversing motors 16. The discharge means, at the other end of the beds, comprises a roller way 17 and beams 18 fitted near their ends with bars 19 projecting between the bars of the beds. The beams are traversable similarly to the pushers 7, 10. Associated with each beam is a straight edge 31 adjustable as to its distance from the beam by racks engaging pinions on a shaft 34 on the beam and operated either manually at 37 or by worm gearing from a reversing motor. In the latter case the motor is mounted on the beam but the current supply contacts are so arranged that when the beam is advanced towards the cooling-bed the circuit is broken. When the adjustment is manually effected, hooked pawls 35 serve to lock the racks after adjustment. The bars 19 carry pawls pivoted at 27 so that they can pass under the bars on the cooling-bed, swing- ing into the position shown in dotted lines in Fig. 3. On the return of the beams 18 towards the discharge rollers the ends 29 of the pawls rise and shift the selected number of bars into position on said rollers, the number depending on the distance between the pawls and the set position of the straight-edge 31. A number of intermediate bars 25 carry pawls in alignment with those on the bars 19 so that trouble in removal will not arise due to bars shorter than the normal.
