Title: An improved method of and apparatus for disintegrating, dehydrating and otherwise treating peat for fuel or distillation purposes
IPC: C10F5/00
Filed: 1921-04-25
Abstract: 183,566. Clewlow, C. W. G. April 25, 1921. Multi-stage processes. - Disintegrated peat worked into a thin paste with milk of lime and water if necessary is continuously forced through a region heated above atmospheric boiling temperature and abruptly enters a low pressure region, by passing a loaded valve. wherein evolution of steam completes the disruption of the cellular tissues and water is liberated. The peat cream arrives by a pipe a having a relief valve a<1>, and is urged forward by a steam jet at about 130 lb. pressure injected by a nozzle b<2>. The peat then traverses a heater c which provides a jacket maintained about 300‹ F. round a serpentine continuation of the peat pipe. The peat cream is then forced into one or other of two branch pipes e<1> and receivers e, after passing through an annular space into the abrupt pressure relief device f, which contains a plunger f<1> and a valve thrust towards a seating in the delivery pipe d. The valve may be loaded by a weight f<3> by a weight bearing directly on the plunger or by weighed levers. Steam and vapour escape by a pipe g to an upwardly directed separating chamber h provided at the base, with a conical perforated cone h<1> surrounded by a drainage space. A steam jet is injected into the pipe g to assist in disrupting peat carried up. Uncondensed vapour passes to a flue h<3>.

Title: Improvements in or relating to a flake mica separating and film forming machine
Inventor: BADGER RICHARD ALAN
IPC: B03B4/04
Filed: 1961-04-04
Abstract: 966,607. Endless conveyers. GENERAL ELECTRIC CO. April 4, 1961, No. 11958/61. Heading B8A. [Also in Division B2] A conveyer belt to the surface of which a vacuum is applied, is used in a flake mica filmforming machine to convey the mica flakes and also to separate the single-thickness flakes from clumps of flakes. The conveyer comprises a foraminous belt 12 which on its upper run overlies a perforated plate 18 (Fig. 6). The latter extends to the point where it joins an unperforated baffle 19 on the lower run, and at this point the vacuum is thus broken and the flakes drop into a shoot 10. The thicker clumps of flakes, however, due to the fact that they will not bend with the belt around an idler roller 15, tend to fall into a shoot 23 by means of which they are separated out. The flakes pass from the shoot 10 to a conveyer belt 26 to which vacuum is applied in the same way as to the belt 12. The flakes generally are retained on the lower run of this belt but any excess falls on to a rotating disc 33. Flakes on the disc 33, as they pass under the belt, are agitated mechanically or pneumatically and thus may be picked up to fill any voids of flakes on the belt. The conveyer belt 26 conveys its flakes into contact with a web 37 which has previously been coated with a suitable resin binder at 38 and subjected to a dryer 43. The flakes on the conveyer belt 26 are thus transferred to the web 37 with a bonding action and a further supply of resin is applied over the flakes and the web 37 at 47. A second web is then applied continuously to the second resin layer (Fig. 2). The sandwich web thus produced then passes through further apparatus similar to that shown in Fig. 1 by means of which a further layer of mica flakes are applied and finally to apparatus in which a further web of material is placed on top of the material already formed.

Abstract: 1,117,846. Teaching gunnery. CONTRAVES, A.G. 22 March, 1966 [2 April, 1965], No. 12482/66. Heading F3C. An apparatus for simulating firing on a freely movable target comprises a television camera trained on the target by the gunner, distance adjusting means into which the distance of the target estimated by the gunner is fed and a distance error computer for ascertaining the difference between the estimated and actual target distance. A video store member is also provided which stores momentary camera pictures and a flying time computer which is set in operation by the gunner releasing a firing signal and which after the flying time for a projectile over the estimated distance interrupts any further storing of camera pictures in the video store. The firing signal also actuates a means which prevents the camera from being trained further in azimuth and locks the distance adjusting means. A difference signal from the distance error computer is then fed into the video store to superimpose a hit pattern on the last picture from the camera such that the hit pattern is produced on the vertical diameter of the picture field with an upper and lower offset relative to the centre of the picture corresponding to the distance error. The television camera may serve as the gun or it may be mechanically coupled to a gun. The real distance is ascertained from a distance measuring device.
