Title: Improved process of and apparatus for roasting cocoa beans and the like
IPC: A23N12/08
Filed: 1920-05-10
Abstract: 143,224. Pannevis, M. Feb. 1, 1919. [Convention date]. Void [Published under Sect. 91 of the Act]. Roasting granular substances.-Cocoa beans and the like are roasted in receptacles heated by a surrounding liquid, such as glycerine, which is maintained at or near its boiling point. The material is conveyed from a feeding-device 5 by worm conveyers 3 through a series of tubes 2, which are surrounded by the liquid contained in the casing 1. The central tubes may be of larger diameter to allow for the temporary expansion of the beans. A gauze-covered outlet 13 is provided for vapours from the cocoa, and the casing is connected to a condenser by the pipe 16. The time of treatment is varied by varying the speed of the conveyers.

Title: Improvements in and relating to spaced self-supporting electric coils
IPC: H01F17/02
Filed: 1924-05-27
Abstract: 234,635. Hake, E. G. May 27, 1924. No Patent granted (Sealing fee not paid). Inductances.-A multi-layer inductance coil comprises turns of wave or zig-zag form, the wave forms of adjacent layers being oppositely disposed, the corresponding peaks or bends of the waves being in the same straight line. Figs. 1 and 2 show developments of cylindrical coils wound on cylindrical formers A. In Fig. 1 the former is divided into an odd number of divisions, the winding commencing at the division 1 and proceding in zig-zag fashion until it reaches the division 7, when it proceeds to division 2, the zig-zag winding being continued to the opposite edge of the former or until the required number of turns have been obtained for a single layer. The next layer is then wound with the wave forms reversed as shown at R. In the modification shown in Fig. 2 the former A is divided into an even number of divisions, and each turn follows a helical path. When the final turn S arrives at the division 1 it is brought vertically down the division 1 as shown at T, the next layer being wound with the wave forms in the reverse direction. The peaks or bends of the waves in both modifications are situated in the dividing lines on the formers A. Fig. 7 shows a disc form of coil, the bends of the waves of each layer lying on the radii of the disc.

Abstract: 785,766. Variable pitch propellers. ROTOL, Ltd. May 1, 1956 [May 5, 1955], No. 13075/55. Class 114. A pitch lock valve 5 in the coarse pitch conduit 4 of an hydraulic pitch motor 1, 2 is urged to close by a spring 6 and to open by the combined force of pressure from the fine pitch conduit 3 acting through a conduit 10 on one end of the valve 5 which may be of the piston type and pressure from the coarse pitch conduit 4 acting on one side of a piston 13 in a cylinder 15, the opposite ends of the cylinders of the pistons being connected to a drain 12 and the piston 13 having a piston rod engaging the end of the piston valve 5. A lift valve may replace the piston valve 5 which is bye-passed by a conduit 7 having a spring pressed valve 8 adapted to be closed while the pressure on the coarse pitch side of the motor exceeds that below the valve but to permit fluid under pressure to be forced into the motor cylinder 2 to coarsen the pitch when the pressure is sufficient to overcome the spring of the valve 8.

Abstract: 652,893. Rod couplings. FORD, C. M. May 12, 1948, No. 13077. [Class 99(i)] [Also in Groups X and XXII] To enable the web of a T or Y section directly to receive a bolt or the screwed end of a rod in the plane of the web, this has a number of slits made parallel to the edge and the resulting strips 3, Fig. 3, are offset on opposite sides to form a socket that is tapped to receive the bolt. Panels 6, of a wall or partition are clamped to the flanges 7 by a cover strip or series of clips 8 secured by the bolts 4. A ceiling joist 7, Fig. 4, is suspended by tie rods 4a and lock nuts 10 are received in holes punched in the web. Glass 13, Fig. 5, is secured to glazing bars 7 by rubber beading 12 held in place by a capping-strip 11 secured by the bolts 4. A similar construction for clamping these plates employs small channel section clips passed through holes in the web. The flange 7, Fig. 8, of a T-bar are cut away to receive one flange of an angle bar secured by bolts 4 to offset strips formed in the web 2. In the case of a T formed by folding a strip to give a web of double thickness, a notch is cut in the fold and the two parts of the web are separated to form the screw socket.

Filed: 1971-05-05
Abstract: 1349863 Moulding ceramic pipes SCHNEIDER & CO 5 May 1971 [6 May 1970] 13167/71 Heading B5A In a method of producing branched ceramic pipes in a mould having a main mould cavity part 1 and a side cavity part 2, ceramic material is introduced into the mould cavity, compacted by pistons, and then shaped into a tubular form by the introduction of mandrels 8, 9 into the parts 1, 2, the mandrels being vibrated to facilitate their insertion into the compacted material. The vibration preferably takes the form of a "relative translatory circular movement" of the mandrel axis about the cavity axis such that any point on the mandrel axis moves in a substantially circular path around the axis of the cavity the orientation of the mandrel in relation to its own axis remaining unchanged during movement around the circular path. The mandrels have an external diameter which is smaller than the eventual diameter of the finished moulding by an amount equal to twice the vibration amplitude. In an alternative embodiment, the mould may be vibrated instead of, or in addition to, the mandrel. The vibrating may be effected by mechanical or electromagnetic means. Also described (Fig. 5, not shown) is an arrangement for supporting the mandrels and directing insertion into the mould cavity of the mandrels.
