Title: Improvements in devices for sealing a longitudinal overlapping seam
IPC: B65B51/16
Filed: 1955-11-25
Abstract: 795,015. Seaming non-metallic sheet material. HERMORION, Ltd. Nov. 25, 1955 [July 8, 1955], No. 33826/55. Class 42 (1). Means for pressing together and sealing a longitudinal overlapping seam in the production of a continuous tube or cylinder from a sheet or strip material includes two co-operating rollers acting as a pressure roller and a backing roller respectively, in which the pressure roller is journalled in one end of a link member for rotation about its own axis, the link member being provided at its other end with a universal joint support and carrying a further roller arranged to transfer operative pressure to the pressure roller. In the arrangement shown, 10 indicates a part of the machine frame supporting an upper shaping element 12 and a lower shaping element 14 between which is located a heating unit 16 for heating the overlapping edges of the sheet material. A bracket 18 is attached to frame 10 and supports a feed tube 20 for the supply of pourable material into packages simultaneously with their formation. The packaging material 22 is formed into a tube by the shaping elements 12 and 14, each of which is provided with a ring of concave rollers 24 contacting the outside of the tube. One of these'concave rollers 24 of the lower member 14 and indicated at 24a serves as a backing roller in the process of pressing and sealing the seam. A pressure roller 26 operates in conjunction with the backing roller 24a and is carried by a lower forked end 28 of a link member 30 having its upper end journalled by means of a universal joint in a housing 36 supported on feed tube 20, the whole being covered by a cover 38. The link 30 also carries a roller 42 which is arranged to bear against a cam or guide surface 44 of the housing 36. Pressure is exerted between the roller 24a and the roller 26 by applying a force to the bracket 18 which is carried on a pivot pin 46, such that the end of the bracket connected to the pipe 20 is forced downwardly. This force is transmitted to the pressure roller 26 by the supply pipe 20, housing 36 roller 42 and link member 30.

Abstract: 457,078. Thermostats. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., Cricklewood, and GROSE, F. J., 11, Slough Lane, Kingsbury, both in London. Dec. 6, 1935, No. 33892. [Class 135] A thermostatically operated valve device especially adapted for use in the cooling systems of internal combustion engines is constructed as a unit for insertion in a fluid conduit. The thermal bellows 10 is secured in a stirrup 12 the arms of which are secured to a ring 13 provided with a flange 15 for clamping between two parts of the fluid conduit. The upper edge of the ring 13 forms a seat for a lift valve member 18 mounted on a spindle 16 secured to the movable wall of the bellows and guided by a cross-bar 17. A second valve member 21 controlling a bypass is formed on an arm 20 pivoted to one of the arms of the stirrup and is coupled by a pin and slot to a bracket on the spindle 16. This valve member co-operates with an inclined seat 27 and is arranged to close as the valve 18 opens.
Patent GB-829506-A (GB)
Title: Improvements in the manufacture of wood putp
IPC: D21C3/22
Filed: 1957-10-30
Abstract: Wood pulp is prepared by partially leaching wood with a lye containing sodium sulphite, an alkaline hydrosulphite, preferably sodium hydrosulphite, and oxalate ions and thereafter grinding the leached material.  The oxalate ions may be provided by addition to the lye of sodium oxalate or oxalic acid.  The wood may first be impregnated with a lye of such concentration that the reagents retained within the wood are sufficient for at least partial leaching, and thereafter leaching may be effected by use of a lye substantially more dilute than the lye for the impregnating step, e.g. a lye 3-6 times more dilute or a lye containing only sodium sulphite.  The liquor from a preceding operation may also be used for leaching.  The initial pH of the lye may be adjusted, e.g. by adding sodium carbonate so that, after the leaching step, the pH is between 5-7.  The impregnated wood may also be leached by the use of steam in the absence of liquid.  Examples are given.

Title: Improvements in or relating to containers for powdery or granular materials
Inventor: BRAMALL JOHN WALTER
IPC: B65G53/00
Filed: 1959-10-07
Abstract: 880,370. Pneumatic conveyers. PORTASILO Ltd. June 1, 1960 [Oct. 7, 1959], No. 34044/59. Class 78 (1). The invention relates to a container 1 for powdery or granular material which can be discharged from the container 1 under the action of gas under pressure to fluidize the material so that it will flow out of the delivery pipe 7. According to the invention, a valve 13 is provided on the outlet side of the inlet 9 to the pipe 7 and means 16 are provided for opening the valve 13 even when the container is filled to its normal height with material. The valve 13 serves, when open, to act as a by-pass for material to flow directly into the pipe 7 and so enable delivery to continue in spite of a blockage of the inlet 9. Compressed-air is supplied to a space 5 below a porous floor in order to fluidize the granular material so that normally it will flow out of the container into the inlet 9 under the control of a valve 8. A non- return valve is provided at 10 between the interior of the container and the pipe 7. The means 16 comprises a handle which may be disposed to pass to the outside of the container. There may be a plurality of valves 13 at different levels, each having separate actuating means. The valve 13 may be a sleeve valve having either rotary or axial operation. Specification 871,972 is referred to.

Title: Purification of slightly water soluble c5 alcohols
Inventor: SCHEELINE HAROLD WENDEL
IPC: C07C29/74
Filed: 1958-10-24
Abstract: <PICT:0841803/III/1> In the purification of crude C5 alcohols containing C10 hydrocarbons and other impurities, e.g. amyl alcohols produced by the "Oxo" process, the crude alcohol is fed by line 2 into a fractional distillation column 1, steam is introduced by line 4 and, if desired, also by line 2, the amount of water added as steam being sufficient to saturate the alcohol refluxing in the column 1 but insufficient to form a second liquid phase, C10 hydrocarbons and light impurities are removed overhead, the residual alcohol reflux containing heavy impurities is stripped of remaining water in a drying section 23, and dry C5 alcohols are distilled from the heavy impurities in a column 15.  Overhead vapours from column 1 proceed by line 8 through condenser 9 to receiver 10 where two layers separate, a bottom water layer containing some of the alcohols which is discarded through line 11, and an upper oil layer containing hydrocarbons with some aldehydes and alcohols.  Part of the upper layer is withdrawn by line 12 while part is refluxed by line 13 to an upper part of column 1.  The drying section 23 is maintained by a reboiler 5 and recycle lines 6 and 7, the reboiler vapourizing the bottoms and stripping them free of water.  Dry C5 alcohols and high boiling impurities are separated by straight distillation in column 15, overhead being withdrawn by line 16 through condenser 17, a part of the overhead being refluxed by line 18, while the remainder is withdrawn by line 19 as pure alcohol product.  High boiling impurities are drained from the bottoms by line 20 and a part is recycled through reboiler 21 and line 22.
