Abstract: 616,187. Shelling peas. WHITTINGSLOWE. W. T. Aug. 7, 1946. No. 23439. [Class 28 (ii)] Peas are shelled between rollers 8 and 9 the nip of the rollers being out of alignment with the plane of the feed-in so that the pods are bent as they engage the rollers. The top roller is forward of the bottom roller, to effect this mis-alignment and also to provide clearance for the peas to fall away. The rollers are mounted between pressed metal or die cast end plates 1, 20 the plate 1 being extended to form a table clamp mounting. The end plates receive between them a cover 30 with front and back openings for the pods, the lower end of the front opening being flanged inwards at 46 to form a guide and rest for the pods. This guide may be replaced by a third roller. The end plates and cover 30 are secured together by metal tongues engaging in notches 13, &c., in the end flanges. The rollers are geared together and may be driven by an electric motor. A hopper may be arranged to feed the pods between the rollers.

Abstract: 760,372. Smoke and ventilation shaft arrangements. VAN DE POL'S HANDELSONDERNEMING N. V., E. M. Aug. 17, 1954, No. 23924/54. Classes 25 and 137  The arrangement of shafts provided in a building for the purpose of carrying off combustion gases or for ventilation comprises an upwardly extending main shaft and auxiliary shafts running in vertical direction and each connected at one end to the main shaft and the other end to a ventilation orifice or fire, wherein the vertical distance between the orifice by which the main shaft debouches into free air and the nearest connecting orifice between the said shaft and an auxiliary shaft is 12 feet or more. The smoke removal system shown (Fig. 1) comprises a main shaft 1 with auxiliary shafts 2, 3, 4 running parallel and adjacent to it. These shafts connect heating appliances 5, 6 and 7 to the main shaft whose upper part 6a is provided with a chimney cap 5a. The distance between orifice 13 connecting the auxiliary shaft 4 with the main shaft and the cap 5a must be 12 feet or more. In a modified system where the distance beween the cap 5a and the point of connection of the auxiliary shaft on the top floor of the building with the main shaft would be less than 12 feet no connection between the shafts is made the auxiliary shaft being carried out to the atmosphere as an independent one. In the ventilation system shown in Fig. 3 a main shaft 28 with associated auxiliary shafts 30, 31, 32, 33, provides fresh air to rooms on storeys 49, 50, 51, 52, 53 whilst foul air is removed from the rooms by a main shaft 29 with associated shafts 39, 40, 41, 42. As the vertical distance between orifices 34 and 55 and orifice 47 and the chimney cap is less than 12 feet both orifices, i.e. inlet orifice 34 and outlet orifice 47, are connected to the atmosphere by shafts independent of main shafts 28, 29, respectively.

Abstract: 351,303. Printing-machines. HUCKINS, A. S., 257, Diamond Street, Philadelphia, U.S.A. Aug. 11, 1930, No. 24009. [Class 100 (i).] Sheet-separators; pile supports; grippermechanism.-Envelope blanks 1 are fed to the impression cylinder 2 of a rotary printing couple by means of a suction separator 17 mounted on an oscillating shaft 11 carried by endplates 12, 13 of the cylinder2, the nozzle at the end of the separator being moved outwardly from the cylinder at each rotation to. engage the foremost blank of the pile 1, and to separate a blank therefrom. The separator 17 is connected by a flexible tube 19 to the hollow shaft 5 of the cylinder 2, and the shaft 5 is periodically exhausted of air by means of a pump 4 and an oscillating valve which connects the shaft 5 to the pump. The movement of the separator 15 is controlled by means of an arm 14 which is secured to the shaft 11 parallel to the separator 17, and a fixed cam segment 15 which acts on the arm 14 and rotates the shaft 11 against the action of a spring 16. After the separator 17, which is formed with an orifice of oblong shape with the long side thereof parallel to the axis of the shaft 5, has seized a blank it remains substantially parallel to its original position, but is withdrawn into the cylinder 2. It moves backwards relatively to the cylinder 2, and the separated blank is gripped by an oscillating gripper 26 on a spring-controlled shaft geared to an oscillating segment. The pile 1 is retained by a holding device 21, and an oscillating picker 22 assists the separation of the blank by moving down between the holder 21 and the blank attached to the separator 17. After the arm 14 is released from the cam 15, the parts 14, 17 return to their original position relatively to the cylinder 2 under spring action. The blanks are printed on by a cylinder 29, and are detached from the cylinder 2 by a stripper 31 and stacked in a pile 32.

Title: Improvements in and relating to the treatment of cellulosic textile materials
IPC: D06M15/423
Filed: 1938-08-15
Abstract: 517,890. Treating textiles with liquids; resinous condensation products. COURTAULDS, Ltd., and BOULTON, J. Aug. 15, 1938, No. 24023. [Classes 2 (iii) and 15 (ii)] The resistance to creasing of cellulosic textile material is improved and the material is also delustred by treating it with a cold aqueous solution containing two distinct water-soluble urea-formaldehyde precondensates to which solution there has been added, shortly before the treatment of the material, an acid or acidforming substance which initiates and assists the process of rendering insoluble one of the precondensates in the cold, but which only causes the other precondensate to become insoluble when heat is applied, and subsequently drying and heating the so-treated material. The first precondensate rapidly becomes deposited on the fibres during the cold treatment and is distributed in the form of fine particles which cause delustring. The other precondensate is converted into a synthetic resin during the heat treatment and gives the anticrease effect. In an example, urea is shaken with formaldehyde solution and strong caustic soda is added to give a pH value of 7.5-8. Ammonium hydroxide is added and the solution is refluxed with vigorous heating for a few minutes followed by cooling. A clear syrup is obtained. Another precondensate is prepared by mixing urea and formaldehyde and adding caustic soda to give a pH of 9. The solution is shaken for several hours at room temperature. The two precondensates are mixed together with lactic acid, ammonium sulphate and water. Viscose rayon crepe is padded with the cold solution. It is run on a mangle bowl or hung in the air till delustring is observed. It is then dried and subsequently heated to 145‹ C. Specification 499,207 is referred to.

A string of elongate nuclear fuel elements superposed one upon another to form a column has means whereby the string can be lifted and lowered as a unit, with the lowermost element suspended from the means and the other fuel elements supported axially on the lowermost fuel element, the means being removable from the elements by an operation remote from the elements. In the embodiment shown in Fig. 1, fuel elements 11 having helically extending swirlers 13 projecting to the inner surfaces of graphite sleeves 12 are suspended in end-to-end relation by means of a cable 25 which passes down through tubes 17 secured to one side of the elements 11, through an arc-shaped tube 20 incorporated in a bridge 19 extending diametrically across the lowermost sleeve 12 at the bottom of the corresponding element 11, and up through tubes 18 secured to the sides of the elements 11 opposite the tubes 17. At the top of each element 11 is a lifting lug 15 secured centrally in the sleeve 12 by a spider 16 and a bridge (not shown) is fixed diametrically just inside the lower end of each sleeve 12. The tubes 17, 18 extend between the spiders 16 and the bridges, the swirlers 13 being notched to give free passage to these tubes. Each element 11 with the exception of the lowermost is provided with a tube 22 in a'similar manner to the tubes 17, 18 but mid-way between them, the wire 23 from a thermocouple fitted to the lowermost element passing up this tube 22 to join the wire 24 from a thermocouple fixed to the uppermost element. The lengths of cable 25 extending above the fuel element string are encased in flexible metal conduits 26 of helically wound wire which can be coiled together with the cable on a winding drum. Both conduits 26 have their ends anchored between the halves of a split dolly 27, the bottom end of which presents a cone 30 engageable in a cup in the lifting lug 15. After the string is inserted within a reactor core, one end of the cable is freed at the winding drum and the cable pulled out of the fuel elements, the dolly then being withdrawn by rewinding on the winding drum. In an alternative embodiment (Fig. 3), a Bowden cable 51 extends along opposite sides of the fuel element string in flexible guide tubes 52 s supported at intervals along the length of the string by brackets (not shown) attached to the longitudinal fins 43 of the element 40, and through a passageway 48 and curved hollow arms 49 of an end fitting 41a. After the Bowden cable 51 has been removed, the flexible tubes 52 are withdrawn. As an alternative to a looped cable, two separate straight cables may be used, each being secured to the lower end of the lowermost fuel element in the string so that they are releasable when the string is in position in a reactor channel.
