Patent GB-1173950-A (GB)
Title: Sieves
Inventor: ARNOLD ARTHUR JOHN
IPC: B07B1/00
Filed: 1967-07-12
Abstract: 1,173,950. Vibrating sieves. NATIONAL RESEARCH DEVELOPMENT CORP. 10 July, 1968 [12 July, 1967], No. 32024/67. Heading B2H. A variable-pass sieve comprises a coil spring 1 extending between two supports 2, 3, means for adjusting the length of the spring, means for vibrating the spring in a direction normal, or having a component normal, to the longitudinal axis of the spring, and means for introducing axially of the spring matter to be sieved. The support 2 is secured to a frame member 4 between which and another frame member 7 guide rods 5, 6 are secured. The support 3 is connected to a slide 8 whose position on the guide is adjusted by means of a threaded shaft 9 to adjust the length of the spring 1 and hence the pass of the sieve. The spring is vibrated by means of electromagnetic vibrators 15, 16 connected to the frame members 4, 7 and mounted on top of a cover 17 of a trough 18 of downwardly wedge-shaped cross-section in which the spring 1 is immersed in liquid maintained at a level 27 and flowing from an inlet 21 to an outlet 22. The material to be sieved, e.g. dead insects, is supplied in a liquid vehicle via a conduit 25 to the interior of the spring. A damper 26 is adjustably mounted on the guide rod 5 and constrains that portion of the spring to which it is adjacent to vibrate in phase with, and with the same amplitude as, the end portions of the spring. If the material being sieved is denser than the liquid vehicle, which is usually the same as that flowing through the trough, it will sink and the finer material will pass between the turns of the spring to the exterior of the spring and is carried in the liquid flow and discharged at 22. The coarser material, in the case of batch separation, remains inside the spring and is subsequently removed therefromby lengthening of the spring. If the material being sieved is less dense than the liquid, the latter is arranged to flow outwardly through of the spring. Where continuous sieving is required the support 3 may be provided with a conduit similar to conduit 25 whereby liquid may be withdrawn from within the spring with the coarser material. The spring may be a compression or a tension spring. The pitch of the spring helix and hence the spacing between adjacent turns of the spring may be uniform or non-uniform throughout the effective length of the spring. The spring may be conical instead of cylindrical. When viewed axially, each turn of the spring may be rectangular instead of circular. The spring wire may be of circular or rectangular cross-section. The length of the spring may alternatively be adjusted by pneumatic, hydraulic or electrical means. The spring may not be immersed in a liquid and the material to be sieved may or may not be introduced in a liquid vehicle.

Title: A machine for producing cement tiles
IPC: B28B3/12
Filed: 1932-11-15
Abstract: 400,429. Moulding tiles. FLAMAND, S., 5, Naestvedvej, Ringsted, Denmark. Nov. 15, 1932, No. 32288. [Class 87 (ii).] A machine for making cement tiles comprises a supply conveyer 47 travelling at a greater speed than, and serving to supply bedplates 13 (upon which the tiles are formed) to a main conveyer 39 by means of which the bedplates are carried forward in a continuous row, in which succeeding bedplates abut against each other, beneath the lower open end of a mortar box 14. The bedplates may be moved along rails 12 so that the bedplates pass below a punching device 16 and a colour applying device 17 to a delivery conveyer 45, the speed of which is greater than the speed of the main conveyer. The rails 12 are formed with a recess 50 into which the rear end of each bedplate slides down when the front end is engaged by the delivery conveyer, thus separating the edge of the tile on a bedplate from the edge of the tile lying on the next bedplate. In this way the tiles are produced as a continuously moved and continuous progressive series which is not divided until the bedplates have passed all the steps of production within the machine. The layer of mortar supplied to the bedplates by the mortar box 14 is compressed by a drum 15 located at the rear edge of the box. As shown in Fig. 3 the profile of the drum 15 is in conformity with the profile of the bedplate and is provided at its ends with flanges 55 that serve to limit at the sides the amount of mortar passing beneath the drum. A substantially vertical partition 52 adjustable preferably in a vertical direction by handwheels 53 may be provided in the mortar box to control the level of the mortar. Before the bedplates reach the mortar box they may be sprayed with oil from a nozzle 20 in order to prevent adherence of the mortar. After passing the drum 15 the mortar may be further compressed and smoothed by a sleeking device, not shown. The punching device 16 comprises a rod 56 suspended from a lever 57 and normally held raised against an abutment 61 by a spring 58. An arm 59 attached to the lever 57 co-operates with studs 60 on a cam disc 18. Upon one of the studs 60 passing beneath the notched end of the arm 59 the lever 57 swings in a clockwise direction, whereby the lower end of the rod 56 is caused to penetrate the tile which at the moment is immediately below the punching device and to move along with the tile as long as the end of the rod is in engagement therewith ; when the engagement ceases the rod by its weight is returned to its initial position. The colourapplying device 16 has a drum 19 for applying colour in powder form. An electromotor 24 through gearing serves to drive the conveyers, the drums 15, 19 and the disc 18.

As shown, a rail 1 is connected to guide tubes 5, 6 having sliding sleeves 7, which are horizontally displacable on longitudinal rails 8, 9, and can be locked in the desired position by spring locking means 10. The rails 8, 9 are secured to the lateral wall by brackets 21, 22. The rail 1 is pivotally mounted at both ends by means of minnions 2 in sleeves 3, which are connected to the tubes 5, 6. The rail 1 can therefore be pivoted about the minnions, then locked in position by spring locking means 23. A carrier arm 36 connects the seat to a housing 26, which is slidably mounted on the rail 1. The vertical adjustment of the seat is effected by loosening a spring bolt 35, which allows the housing 26 to be pressed upwards by a compression spring 33, and locked by spring bolt 35. The housing 26 slides on ten needle bearings 27 which prevent the seat from tilting. The seat 41 is a tip-up seat, with reinforcing ribs 42, hinged about pivot 43 by means of two axle springs (not shown). The back rest 45 is secured to sleeve 44, which is loosely positioned on a tube 40 between fish plates 39, so that the back rest can pivot about the tube and be secured in position by locking means 48. This enables the back rest 45 to be held in one of two alternative raised positions or to be lowered down to a horizontal position.

Patent GB-618568-A (GB)
Title: Improvements in method of treating wheat
IPC: C08B30/04
Filed: 1946-11-05
Abstract: Starch and gluten are extracted from wheat from which bran and shoots and germ have been removed and which is in flour or, preferably clears form, by mixing with sufficient water to form a soft dough but insufficient to dispense the gluten, so as to hydrate the gluten and develop its strength, more water being then added to subdivide the gluten and wash out the starch in the form of a slurry.  The flour and 85-115 per cent water are mixed in a tank (see Group II) at a temperature of 50-55 DEG  C.  During the first part of the mixing an elastic dough is produced, which is stretched and washed until the starch is washed out, after which the gluten is disintegrated by the mixing elements.  The mass is passed to separating screens where the starch solution is filtered away.  The gluten is washed to remove last traces of the starch, the wash water being returned to the mixing tank.  The gluten is then passed to a dividing-apparatus, preferably in the form of an extruder to divide the mass into a number of strings which are passed into a coagulation tank containing water of at least 71 DEG  C. from whence it is passed to washing, drying and grinding apparatus.  The wash-water which contains small amounts of starch is passed into the liquor from the mixing tank, and this liquor, containing 15-24 per cent starch solids passes to conversion apparatus for the production of dextrose.  After neutralization and filtration, the product is passed through vegetable carbon for decolourizing and then to a vacuum evaporator. A proteolytic enzyme may be added to solubilize any protein residue still remaining which may amount to 2-4 per cent, and an anti-foaming agent, e.g. an edible oil such as cottonseed oil, can be added. The syrup is then further decolourized, and finally treated for the production of syrup or crystallized dextrose.
