Title: Machine for peeling shrimp
IPC: A22C29/02
Filed: 1955-07-07
Abstract: 773,264. Shrimps, shelling. LAPEYRE, F. S., LAPEYRE, J. M. LAPEYRE, A. C., LAPEYRE, F. H., LAPEYRE, E. M., and RIESS, F. E. [trading as PEELERS CO]. July 7, 1955, No. 19645/55. Class 28(2) Shrimps are peeled by yieldingly and intermittently pressing them into the nip of a pair of rolls 28, 30,   Fig. 2, which grip some of the legs and shell of one side and pull them away from the shrimp which turns over freely in the nip, the shrimp then passing over the roll 26 to another pair of rolls 29, 27 which likewise grip some of the legs and shell of the other side and pull them away from the body. This method comprises the method of U.S.A. Specification 2,537,355. The rolls 27 to 30 are rotated by frictional contact with a driven roll 26 which makes 1¢ revolutions and then similarly reverses, by means of an oscillated rack and pinion Fig. 4. The rollers 29, 30 are pressed towards the other rollers by hold down devices of thin metal (93, 107 not shown). The shrimps are flushed from a hopper 26 towards the peeling device by water. The shrimps are pressed by springs 129 towards the nips by fingers 120 on hinged frames 114 and A and B Fig. 1. Springs 129 in frame A urge the fingers 120 against the shrimp whereas in frame B a shrimp first passes freely beneath the fingers 146 and then after peeling allows free exit. The fingers are intermittently released from pressure on the shrimp by cams. The pressure fingers 120, 146 are caused by cams 109 &c. to rise and fall in synchronous frequency with the rotatory oscillations of the rollers The rollers 29, 30 are held down by an upper hold down (93, 107 not shown) by tension springs. The machine comprises two sections A and B the oscillated rollers 26 extending the length of both sections but the small gripping rollers 29. 30 are discontinuous for each section. Likewise the hold downs of the rollers 29, 30 and also the sets of fingers pressing the shrimp into the peeling nip of the rolls are independent for each section. In the section B Fig. 3 the small rollers are omitted and the peeling is done by the grip of the rollers 26 and their idler support rollers 37. the shrimp being pressed into the nip by different shaped fingers 146, Fig. 23. The rollers of the machine slope downwards from the feed in end so that the shrimps travel axially along the nips of the rollers so that pieces of shell &c. left on at an earlier stage may be removed by the later stages. The oscillatory rotation of the rolls 26 moves the shrimp from the roller nip at one side to the nip at the other side of the rolls 26.

Title: Improvements in and relating to the production of aromatic ketones
Inventor: SMITH PETER
IPC: C07C45/48
Filed: 1952-08-05
Abstract: Aromatic ketones are produced by reacting an aromatic carboxylic acid, in which a carboxyl group is attached directly to an aryl group, with an aldehyde or ketone at elevated temperature in the presence of a decarboxylation catalyst which comprises either (a) chromic oxide, e.g. cadmium chromite, zinc chromite, zinc iron chromite and zinc cadmium chromite; or (b) cadmium oxide, e.g. supported on zinc oxide; or (c) copper, e.g. reduced copper-zinc oxide mixture; or (d) a hydrogenating metal of Group VIII of the Periodic System, e.g. nickel, alone or supported on kieselguhr. Preferably the process is effected in vapour phase at temperatures in the range 260 DEG  to 500 DEG  C. and using excess of carbonyl compound.  A solvent such as toluene may be employed.  A phenyl carbinol is presumed to be formed as an intermediate which is dehydrogenated to a ketone.  Suitable aromatic acids include unsubstituted and alkyl, halogen or nitro-substituted benzoic acids and substituted or unsubstituted naphthoic acids.  Suitable carbonyl reactants include formaldehyde, acetaldehyde, propionaldehyde, benzaldehyde and acetone.  The aldehyde or ketone may also be produced in situ from an alcohol when the catalyst is capable of catalysing dehydrogenation reactions; e.g. ethyl alcohol may replace acetaldehyde when using a reduced copper-zinc oxide catalyst. By-products include the hydrocarbon formed by decarboxylating the aromatic acid, and carbinols or ketones formed from the aromatic acid and dimers or polymers of the carbonyl compound, e.g. propenyl phenyl carbinol or ketone. In examples (1) a solution of acetaldehyde and benzoic acid in toluene is passed over a reduced copper-zinc oxide catalyst contained in a cylindrical converter at 400 DEG  C., through which nitrogen is also passed, to yield acetophenone, with benzene and phenyl propenyl ketone by-products; the process is repeated using (2) acetone and (3) benzaldehyde, the latter giving benzophenone as product; (4) a solution of benzoic acid in ethanol is passed over cadmium oxide to yield acetophenone; (5) zinc iron chromite catalyst is used in the process of example 1.  The Provisional Specification refers also to the production of styrene by dehydration of the phenyl methyl carbinol intermediate formed from benzoic acid and acetaldehyde when the catalyst also catalyses dehydration reactions.
