Title: Improved method of and apparatus for measuring bulk material
IPC: B28C7/04
Filed: 1927-02-15
Abstract: 272,421. White, A. E., (Blaw-Knox Co.). Feb. 15, 1927. Fixed-chamber apparatus for granular materials.-Apparatus for measuring bulk materials, such as sand, broken stone, and cement, in definite batches for making concrete mixtures, comprises means by which the materials may first be measured approximately by volume in hoppers of adjustable capacity, the measurement being completed by weighing. Fig. 1 shows an apparatus consisting of a bin A, divided into compartments 15, 17, for different materials, such as stone and sand, and a hopper B with gate mechanism C for delivering these materials to compartments 16, 18, whence they are delivered simultaneously by opening a door 35. The capacities of the compartments 16, 18 are adjustable by means of plates 21, 24, 27, 28, pivoted at 21<a> - - 28<a>, and adjusted by screw- and-nut gearing 22, 23, &c. The hopper B is slung upon hanger bolts 31, which may be replaced by steelyard-like weighing-devices. The partition 20 extends nearly to the top of the hopper B, and is continued by a detachable extension 33. The gate mechanism C is slidably supported in aagle-irons 7. It consists of a pair of oppositely-moving trough-shaped gates 9, 10, moving on antifriction rollers 12 on tracks 13 attached to the angle-irons. As the gate move, the cross members 34 strike off the top surfaces of the materials in the hoppers. When measuring by weight, the partition 26, 27, 28 may be removed.

Abstract: 859,959. Continuous-discharge and batch mixing apparatus. FARBENFABRIKEN BAYER A.G. Feb. 10, 1958 [Feb. 8, 1957], No. 4273/58. Class 86 [Also in Group V] An apparatus for plasticising, colouring, incorporating plasticisers in a material, and producing granulates, tapes or foils, comprises a smooth cylindrical rotary roller 3, Fig. 1, in a housing 1 having fixed elements 2 uniformly distributed around its inside wall so as to form with the roller surface, wedge-shaped spaces 6 in which the material forms into rolls. The material is fed in powder form through pipe connections 4 and the plasticised material is removed through an opening 5, e.g. as a strip cut from the skin on the roller. It may be removed from each fixed element after having passed through a space between the element and the roller. The elements 2 are either hollow or contain passages for a heating medium or electric heating elements. The material may be granulated by passing through holes 7 in a recessed element 2, Fig. 2, and the granulate cut by a blade 9 in an apertured plate 8 in the recess, and removed by a shoot 10. In another arrangement for forming a foil, the material is passed through a longitudinal slot 11, Fig. 3, in the element 2 having a flexible wall 12 adjustable by a screw 13. In another embodiment two elements 2 are fixed in a frame pivotal on the shaft of the roller so that the torque imparted to the frame can be measured to control the process.

Title: Improvements relating to liquid fuel injectors
Inventor: CORBITT ROBERT WILLIAM
IPC: F02M61/16
Filed: 1949-02-17
Abstract: 665,131. Spray burners. ROLLS-ROYCE, Ltd. Feb. 17, 1950 [Feb. 17, 1949], No. 4414/49. Class 75(i) In a liquid fuel atomizing injector a plurality of air orifices 49 are disposed around a centrally arranged orifice 34 from which swirling fuel emerges to form a conical spray, and the air jets are directed so as to have a component of velocity tangential to the periphery of the fuel orifice 34. The air orifices 49 extend from an annular groove 47 on the back face of a plate 35 to the front face thereof and they are skewed relatively to the axis of the fuel orifice 34 so that the jets lie on a conical surface. The tangential velocity of the air jets is preferably opposite to the direction of the fuel swirl. The injector shown has two fuel orifices 27, 34 arranged coaxially and serving as pilot and main orifices, each having its own fuel supply and swirl chamber. The fuel passes through two separate bores 13, 14 in the body of the injector to recesses 16, 17 in the rear face of a plate 15 abutting the front end of the body. From the recess 16 it passes through a port 18 in the plate 15 and then through a series of passages 28 in a boss 24 at the centre of a second plate 22 to enter a bore 25 forming the swirl chamber for the pilot orifice 27. The other recess 17 in the plate 15 communicates through a hole 20 in the plate 15 with an annular recess 21 in the front of the plate and this recess in turn communicates through a ring of ports 23 in the second plate 22 with an annular recess 30 in the rear face of a third plate 29 having a series of passages 33 arranged to deliver the fuel in a swirl to the main swirl chamber 31 of annular converging shape formed between a frusto-conical flange on the third plate 29 and the boss 24 at the centre of the second plate 22. The air orifice plate 35 abuts the third plate 29 and the four plates are contained in a sleeve 36 engaging the injector body, a nut 37 with an internal flange 37a being screwed on to the injector body to retain the plates in position. Air is supplied by a pipe 41 and passes through ducts 42 to a space 43 between the nut 37 and the sleeve 36; it then passes through apertures 44 in the sleeve to an annular channel 45 in the air orifice plate 35 whence it passes by grooves 46 to the annular groove 47 with which the air outlet orifices 49 communicate; it also passes through a gap 48 between the air orifice plate 35 and the third plate 29 to prevent fuel from clinging to the air plate.
