Title: Improvements in batteries for housing livestock, particularly poultry
IPC: A01K31/17
Filed: 1955-04-28
Abstract: 801,139. Poultry houses. SHEPHERD & SONS, Ltd., J. and SHEPHERD, W. April 30, 1956 [April 28, 1955], No. 12241/55. Class 5(2). In a battery for livestock, in particular poultry, the cages are built of readily removable members so as to facilitate the conversion of the battery or the variation of the capacities of the cages in accordance with the purposes for which the battery is required, e.g. for stock breeding and rearing, or for laying purposes. The battery comprises a skeleton framework of uprights 10, longitudinal frame members 11 and tie rods 12 as illustrated in Fig. 1 upon which rows of cages are arranged back to back and superimposed in tiers. The framework is divided into sections by panels 18 of sheet metal or reticulate form extending between and secured to opposite uprights 10, and the following description will be confined to one row of cages extending between two such panels 18. Removably mounted in holes or mesh openings at the midwidth of the said panels 18 are extensions 16a of a further panel 16 of sheet metal as reticulate form which extends across a complete section and forms the backs of the row of cages therein. The front panel 15, comprising horizontally spaced vertical rods, is mounted on the framework by hooks 15a engaging, in the case of the top tier, holes in the top longitudinal frame member 11a, or in the case of lower tiers, a rod 21, Fig. 5, extending between the uprights 10, two horizontal rods at the bottom of the panel being engaged in holes in the uprights 10 and a feeding trough 22 being suspended from one of the said horizontal rods. Cage-dividing panels 14 are adjustably located in the structure by means of extensions 14a and 14b engaging holes or mesh openings in the back panels 16 and a forwardly extended eye 14c secured to the front panel 15. The floor panel 17 has its rearward extension 17b hooked over the bottom rod of the back panel 16 and is supported at the front by the adjacent longitudinal frame member 11. The floor may be horizontal instead of being inclined. The structure may have incorporated in it a "cafeteria" feeding system as described in Specification 714,268, droppings clearing arrangements as described in Specifications 652,468 or 714,288, and part of it may be adapted to incorporate a brooder with adjustable floors as described in Specification 685,994.

Title: Improvements in means for locking railway carriage and like doors
IPC: E05B65/42
Filed: 1919-05-17
Abstract: 149,446. Gray, F. C. May 17, 1919. Railway-carriage doors and the like, fastening automatically.-Centrifugal apparatus for locking railway carriage and like doors when the train is in motion is constructed with spring-controlled conical weights 8 slidable on sleeves 5 on rods 7 acting through plates 11 to clamp a set of wood blocks 2 secured around the carriage axle 1 so that the parts are driven thereby. The weights in moving outwards under centrifugal action act on rods 10 carried by arms 11 from sliding sleeves 12 on the axle 1 and move the sleeves against the action of springs 13. Flanges 14 on the sleeves contact rolls 15 on arms 16 pivotally supported between a fixed transverse rod 18 and the carriage underframe and connected by links 20 to sleeves 21. When the flanges 14 of the sleeves 12 are moved apart by the action of the weights, the springs 22 slide the sleeves 21 on the rod 18 to operate or control the fastening or other device. As shown, the sleeves 21 operate through links 23 to rock shafts arranged longitudinally of the carriage and provided with arms operating rods 27, Fig. 2, extending up into each latch casing 28 to engage a spring 29 controlling a pivoted notched latch 30 so that this is normally inoperative when the train is at rest. When the train is in motion, the parts operate to engage the notch of the latch 30 with the locking-arm 32 of the usual handle 33, or if this is not turned into locking position, to swing the latch into a recess in the casing of the locking-arm. The latch is bevelled to permit closing of the door, and its shank 35 is shaped for operation by a key when necessary.

Abstract: 592,070. Manufacture of bags. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd. May 17, 1945, No. 12494. [Class 94 (ii)] A blank 11 of heat sealing material is folded to U-shape about a former 12 and a tube, having an upstanding longitudinal seam 16 and a portion sufficient to form the base of the bag extending from the end of the former, is then produced by moving simultaneously towards a web 13 a pair of heated pressure members 14 which, when the web is removed, grip and seal the seam. The seam is folded down on to the tube and the open end of the tube is then transversely distended by a pair of stretchers 18 which, when pressed axially towards the former, flatten portions of the walls of the tube on to the end face of the former and at the same time form triangular tabs 19 extending in the plane of the end of the former together with a projecting end seam 20. The stretchers are withdrawn and the end seam is sealed by a pair of heated pressuremembers 21. To complete the bag the end seam and the tabs are then folded on to the end of the former. A tearing strip 22 may be incorporated in the bag.

Patent GB-700876-A (GB)
Title: A method for producing proteolytic and amylolytic ferments and products containing same
Filed: 1951-05-29
Abstract: In the production of proteolytic and amylolytic ferments by mould culture, the yield of proteases is increased by adding fish protein or its degradation products to the culture medium.  The cultivation of the mould may be carried out in the presence of activating agents (e.g. ammonium salts or certain trace elements), or these may be added to the product after cultivation.  The yield of amylase may be simultaneously increased by arresting mould grown as soon as the temperature of the culture falls to approximately that of the incubator, e.g. by adding an agent capable of suppressing the propagation of the mould, or by rapidly heat-drying the culture at a temperature which will inhibit mould growth without affecting the ferments.  The yield of both types of ferment may be further increased by reducing the speed of growth of the mould below the optimum, e.g. by one or more of the following means: (a) keeping the temperature below that of optinum growth, preferably only slightly above the minimum temperature at which the mould starts to propagate (e.g. by aerating the culture with an increased flow of air of corresponding temperature); (b) adding fungistatic agents (e.g. naphthoquinones, polychlorinated phenols, salicylic acid derivatives, sulphanilamides or antibiotics); (c) diluting the aeration gases with inert gases (e.g. nitrogen or carbon dioxide).  In examples: (1) Aspergillus oryzae is cultivated for 5 days on a mash of wheat bran and fish meal; (2) the fermentation in (1) is continued until the temperature drops (60 hours) and then interrupted, e.g. by introducing vapours of chloroform or ethylene oxide; (3) A. oryzae is cultivated at 18 DEG  C., 28 DEG  C. and 38 DEG  C. on a mash of wheat hull bran, malt sprouts and fish meal, the cultures being dried as soon as conidia are formed.  Other moulds specified are those of the genera Mucor and Penicillium.

Title: Improvements in or relating to preparation of m- and p-diisopropylbenzene
IPC: C07C15/02
Filed: 1954-05-03
Abstract: A diisopropylbenzene substantially free from o-diisopropylbenzene and trimethylindene is obtained by propylating benzene with a propylene-containing gas containing no higher molecular weight unsaturates in the presence of an acid-acting condensation catalyst to produce a reaction mixture rich in o-, m-, and p-diisopropyl benzene, and then contacting the mixture in an isomerization reaction with 0.1 to 2 mols. per cent of aluminium chloride at a temperature of 65-115 DEG  C. until a mixture rich in m-diisopropylbenzene and substantially free from o-diisopropylbenzene and trimethylindane is obtained and separating it by distillation.  p-Diisopropylbenzene may also be isolated by distillation.  The initial alkylation reaction may be catalysed at 50-80 DEG  C. with 80 per cent sulphuric acid, or up to 115 DEG  C. when the catalyst is aluminium chloride.  The isomerization step is effected by adding the aluminium chloride powder preferably at a temperature below 50 DEG  C. and then allowing the temperature to rise gradually to 65-115 DEG  C.  After the reaction has been completed, the catalyst is removed by adding water, preferably containing acid or caustic.  Specification 763,179 is referred to.
