Title: Improvements in or relating to provers for bread doughs and the like
IPC: A21C13/02
Filed: 1946-06-21
Abstract: 613,630. Bread prover. POULTER, H. J., and BAKER PERKINS, Ltd. June 21, 1946, No. 18689. [Class 28(i)] In proving dough lumps by transferring them from one pocket to another within a prover to expose their surfaces uniformly to treatment and encourage the formation of a skin as described in Specification 291,422, the prover has several rings of tiltable pockets, e.g., A-F and A<1>-F<1> arranged about a horizontal axis each dough lump being transferred after one revolution downwardly and axially, e.g., from pocket A to a lower pocket B in the ring of pockets B. The pockets travel in a circulatory path about a horizontal axis, e.g., by being mounted on bars 11 and 14 between rotated end rings 2 and 4 respectively. The pockets A &c. are individual but pockets A to E may be combined to form elongated horizontal trays. Pockets A to F also may be combined into single horizontal trays with final delivery from F so that a dough piece does not travel through both outer and inner rings. Transfer from one pocket to another is by the usual fixed cams which tip each pocket when it arrives after one revolution, at the top. The dough lumps are delivered from a feed chute 12 by hand or automatically, and after making one revolution in one pocket of each ring of pockets in succession, are transferred from the ring F to the ring F<1> from which they travel back in the same way from ring F<1> to ring E<1> and finally back to A<1> during rotation within the prover and are ejected finally from a delivery chute 13 (Fig. 7 not shown) The rings 2 and 4 run on groups of anti-friction rollers 3 and 5 respectively and have toothed rings and driving pinions, e.g., 8, 10, &c., Fig. 3. The initial feed of dough lumps may be to an inner group, e.g., A<1> of pockets from which they are transferred to an outer group before final delivery. Alternatively, each group may be fed with dough lumps and may finally deliver its own lumps outside independently of another group.

A three-block polymer which is elastomeric at ambient temperatures and thermoplastic at higher temperatures is prepared by condensing two molecules of a non-elastomeric monofunctional polymer A of mol. wt. 3000-50,000 with one molecule of elastomeric, bifunctional polymer B of mol. wt. not more than 50,000, the two functional groups being attached at respective ends of the polymer B to terminal C atoms, the average C chain length between the two functional groups of the polymer B being equivaleng to a homopolymer of mol. wt.# 2000, the polymers being not mutually miscible at ambient temperatures, the functional groups on the A and B polymers being such that they are mutually reactive and the mol. wt. of each polymer A block not exceeding that of the polymer B block. In examples (1) a di-hydroxy terminated polybutadiene prepared by sodium polymerization of butadiene in an aromatic solvent followed by deactivation with air and acid, was reacted with a polystyrene containing a mono-isocyanate group prepared by polymerizing styrene with lithium butyl in benzene followed by treatment with air and methanol and HCl and reacting the hydroxyl-terminated polystyrene with tolylene 2: 4 diisocyanate; (2) and (3) the polybutadiene of (1) was reacted with a polyamide prepared from 25 parts hexamethylene diamine and 26 parts adipyl chloride or adipic acid respectively; (4) the polybutadiene of (1) was reacted with a polyester prepared from ethylene glycol and terephthalic acid; (5) a di-hydroxy terminated polyisoprene was reacted with the polyamide of (2); and (6) a di-carboxyl terminated polybutadiene was reacted with the polyamide of (2) but of reverse diamine/diacid ratio.

Abstract: 208,508. Steenkiste, J. van, and Maerche, J. van. Dec. 12, 1922, [Convention date]. Scutching-apparatus.-A device for scutching flax comprises a holding device 1 for the flax moving along a guide 28, and a pair of long rotary scutching-devices each of which consists of a series of scutching knives 14, 15, 16 mounted on elastic steel spokes 8, 9, 10. The knives of the two devices work in between one another, and the devices are arranged so that the flax hangs loosely between them, and only one blade acts at a time. The spokes are bent at the outer ends, and a plate 19 is mounted on them to support the knives, which have bevelled, plain or undulating edges. The inner ends 7 of the spokes are bent for attachment to a wooden casing 5 round the shaft 4. An outer wooden casing 6 is also provided to deaden the noise. Plates 27 secured to the spokes act as abutments for the flax to lessen the creasing and lashing effect. The knives may be arranged helically, and the spokes may be mounted elastically instead of being themselves elastic.

A process for manufacturing a cylindrical article includes the steps of positioning a blank 16 within a cavity defined by three outer rolls 10, 14 and by a pair of opposed profiling cheeks 42 and 44, urging the cheeks inwardly to decrease the width of the cavity and to impose their profiles on the ends of the blank, simultaneously moving the rolls 10, 12 outwardly to accommodate the increasing diameter of the blank, and finally moving the rolls inwardly to impose their profile on the blank circumference (Fig. 4). During the profiling, spikes 46 may be hydraulically urged towards one another to indent the ends of the blank, and one of the spikes may then be passed through the blank to pierce a hole. The cheeks 42 and 44 are carried on arms 32 which are pivoted by hydraulic cylinders 34 about a hinge 30. Hydraulic motors 52 rotate the cheeks by means of splined spigots 36, the cheeks thereby rotating the blank and hence the rolls 10, 14. The spikes 46 are movable axially by hydraulic cylinders 54. The cheeks 42, 44 may be provided with projections or indentations such as gear teeth, and one cheek is formed with recesses 58, 60 to accommodate excess material during rolling.

In the embodiment shown in which the crane is mounted on a boat 1, Fig. 1, each runway for the gantry 15, Fig. 2, comprises members 7, 8 permanently supported on columns 2, 3; 4, 5 and connected by a girder 10, Fig. 4, and a section 19 which is movable vertically along guide ribs 20 on the columns 3, 4. The section 19 is raised to the position shown in Fig. 1 by the cables 24, 25 of the hoisting trolleys 22, 23. These. cables are passed through blocks 26, 28, 30 and 27, 29, 31, Fig. 5, respectively and anchored at 32 on the deck. The blocks , 30, 31 each engage a tackle for lifting one of the sections 19. The tackle engaged by the block 30 comprises cables 33, 34 passing over blocks 37, 38, 39 and 40, 41, 42, 43 respectively and anchored to the blocks 39, 43, the blocks 38, 42 being mounted on the members 7, 8 and the blocks 39, 43 on one of the sections 19. In a similar way the block 31 is connected to blocks 47, 50 on the other section 19. When these sections are raised to their upper position, their lugs 52, Fig. 4, engage in recesses in members 51 secured to the runway members 7, 8 and the sections are held by nuts threaded on screws 53 projecting through the members 51. In their lower position the sections 19 rest on ledges 54.
