Title: Improvements in telephone rate recorders
IPC: H04M15/28
Filed: 1937-10-27
Abstract: 491,281. Counting-apparatus. SODECO SOC. DES COMPTEURS DE GENEVE. Oct. 27, 1937, No. 29326. Convention date, Oct. 31, 1936. [Class 106 (i)] In a telephone-rate recorder a trip and a total counter are simultaneously operated by current impulses in unison with the subscribers meter at the exchange and the return to zero of the trip counter is effected by a tensioned spring after the former is disconnected from the other counter which remains in its fixed position owing to its connection with the member actuated by the current impulses. For example when the counter 15 reaches its maximum a pin 26 operates a lever 19 which, through levers 20 and 22 releases a dog clutch 14 and allows a spring 18 to zeroize the counter 15. When the latter is zeroized a pin 25 strikes a member 24 and moves a pawl 23 allowing the member 19 to return to its original position and engage the clutch 14. The latter may be dispensed with if the fork 21 is arranged to slide gear wheel 10 into or out of engagement with wheel 7. The counters can be placed on the same axis and be driven by a common shaft 6. In this construction operation of a push button 22<1> releases clutch 14 and permits spring 19<1> to zeroize counter 15. The driving mechanism of the counters in all cases comprises an electromagnet 1 operating a ratchet and pawl mechanism 3 and 4.

Title: Method and apparatus for the treatment of particulate materials
IPC: B65G69/10
Filed: 1973-06-21
Abstract: 1440616 Piling material LAFARGE 21 June 1973 [23 June 1972] 29531/73 Heading B8E [Also in Division B1] A method of blending particulate material comprises uniformly distributing the material in superposed layers on a surface by dropping the material on the surface from one or more points which rotate around an axis and simultaneously move radially of the axis the rotation being continuous in one direction so as to form an annular or part-annular heap of superposed layers of juxtaposed strips and reclaiming material from the heap by extracting radial or sectorial slices from the heap. In one embodiment of apparatus incoming material on a conveyer 37 is fed by a shoot 36 mounted on a central axis 2 to a conveyer 3 which is mounted both for rotation about the axis 2 and for radial adjustment so that the drop point 39 can vary in location over an annular surface 1 with outer wall 35. An annular heap 42 of the materials is formed. A conveyer 43 with scraper elements 44 is disposed, submerged in the heap and is mounted to rotate slowly about the central axis 2 and draws material to a central hopper 47 from which the homogenized material is removed by a conveyer. The outer end of the retrieval conveyer may be mounted by trolley wheels 45 on the wall 35 of the pit. In other embodiments (e.g. Fig. 13, not shown) the incoming material is divided into two portions fed respectively to two rotating belt type conveyers one of which distributes material over the outer part of the surface on which the annular mass is formed while the other distributes material over the inner part thereof the incoming material being divided in proportion to the radial distances of the drop points of the two conveyers. In other embodiments part annular masses may be formed either (Fig. 15, not shown) by temporarily diverting part of the incoming feed on to a reversible storage belt arranged to return the stored material to the distributing conveyer or by directing the incoming material alternately to one of two distributing conveyers arranged extending in opposite directions from the central axis. To provide uniform section strips of material or strips of controlled variation in thickness the radial displacement and/or the angular velocity of the dstributing conveyers may be suitably controlled in relation to the radial distance of the drop point from the central axis. The invention has particular application in the stockpiling and homogenizing of materials used in the manufacture of cement. Where the retrieval conveyer is submerged in the heap a blast of compressed air admitted in the region of the conveyer may be used to assist starting thereof.

Title: Holography
Inventor: GREENWAY DAVID LESLIE
IPC: G03H1/00
Filed: 1968-06-20
Abstract: 1280996 Holography RCA CORPORATION 10 Sept 1969 [20 June 1968 (3)] 29579/68 29580/68 and 29581/68 Heading H4D [Also in Division G2] Holograms are produced by interfering a first coherent wave energy component, encoded with object information, with a second coherent wave energy component which has been acted on by a co-ordinated wave modifying structure (defined), the hologram being such that an image reconstructed therefrom will be modified by said structure. In one embodiment a laser beam 10 (Fig. 5) is split into two beams one of which 12, 84 is collimated and is encoded with information about object 26. Preferably the beam passes a diffuser 24 before the object. The other beam 14 is collimated and passed through a two-dimensional lens array 52 having a common focal plane C-C; the array produces a plurality of divergent reference beams. In effect the array forms a plurality of offset reference beams emanating as if from a plurality of spaced point sources. When the hologram is read-out with a beam equivalent to the original object-beam, but minus the object, a plurality of images are formed in the equivalent of plane C-C (Fig. 6, not shown). In an alternative embodiment the lens array is replaced by a pin hole plate. In a further embodiment (Fig. 10) an annular hologram 200 is formed. A laser beam 212 is reflected by mirrors 220, 214 located on the optic axis O-O of a parabolic mirror 226 and a lens-array 216. Light from mirror 220 passes a diffuser and object 224 located in focal plane of mirror 226 and is then reflected from mirror 226 as a parallel beam 228. Only an annular portion 232 falls on hologram plate 200. Light from mirror 214 passes through the lens array 216 and forms a plurality of divergent beams. Reconstruction of the hologram 200 by a parallel annular light beam from a parabolic mirror gives rise to a plurality of images of the object. The wave energy need not be light. It can be microwaves or acoustic waves. In such latter ease the mirrors and lenses will be of acoustical type.
