Patent GB-2041161-A (GB)
Title: Rollers
IPC: D21G1/02
Filed: 1980-01-28
Abstract: The invention relates to a roller for paper machines, of the kind having a rotatable hollow casing 1 supported by at least one pressure shoe 10 acting against the casing and at least one piston 5 projecting into the latter and braced against a cross-beam 2. The invention is characterised in that the piston 5 is located spherically via annular sealing surfaces 4a against the cross-beam 2, and that in the space between the piston 5, the cross-beam 2 and the sealing surface 4a a pressure acts which considerably reduces or cancels out the pressure of the piston on the sealing surface. Oil may be fed to the space via a duct 3 and to pockets 15 of the shoe 10 via capillaries 4. Preferably, an intermediate ring 4 is fitted between the piston 5 and the cross-beam 2 and may be displaced spherically relative to the piston and linearly relative to the cross-beam 2 in a plane approximately perpendicular to the pressing direction of the piston. <IMAGE>

Title: Preparation of master plates for magnetic duplicating
IPC: G03G19/00
Filed: 1980-01-31
Abstract: Master plates for magnetographic duplicating are prepared by carrying out in either order the following steps:   a) forming image areas in a homogeneous permanently magnetisable layer 1 by making in the said areas a multiplicity of minute perforations, and   b) magnetising the magnetisable layer in a uniform magnetic field.   The perforations in the image areas can be made in the magnetisable layer in several ways. Preferably they are made by means of electric discharges from a needle electrode, the activation of which is controlled by a scanning device which scans the original to be duplicated. The presence of the perforations causes developer to be attracted to their edges in the image areas. <IMAGE>

Title: Coke production
IPC: C10B57/04
Filed: 1981-12-04
Abstract: In the delayed coking of a coking feedstock wherein the feedstock is continuously heated in a coking heater 35 and introduced into a coke drum 36, the heater is operated to provide a coke drum temperature of from 415 DEG  to 455 DEG C, and, after filling of the drum to the desired level, feedstock introduction is discontinued and the coke-drum placed off-steam (36') and the coke drum contents are heated at a temperature of 450 DEG C to 500 DEG C, which temperature is at least 10 DEG C greater than the coking temperature, by passing a non-coking vapour 101 through the contents of the drum to reduce the volatile combustible matter content to a value of 4% to 10% by weight and thereby reduce the CTE of the formed coke. The process is applicable to the production of needle coke in particular from a petroleum feedstock wherein the feedstock is initially treated by thermal soaking in the presence of sulphur, followed by thermal cracking to increase the aromaticity. Noncrystalline substances may be removed prior to coking to further improve the process. <IMAGE>

Title: Slicing cutter for kitchen food-cutting appliance
IPC: B26D1/29
Filed: 1982-01-11
Abstract: A rotary slicing cutter for a kitchen food-cutting appliance comprises a disc (4) formed on one side with raised portions (15), for example in the form of ridges, which provide a surface for supporting and positioning the food during operation of the cutter, the surface lying in a first plane (16) perpendicular to the central axis of the disc. Fixed on the same side of the disc over an opening (7) therein, and on an unraised portion of the disc, is a cutter blade (3), the cutting edge (9) of which lies in a second plane (17) perpendicular to the central axis of the disc. There may be a plurality of such blades. The distance between the two planes determines the thickness of the slices cut by the blade or blades. Different slice thicknesses can be obtained by the use of a set of interchangeable cutters of the above construction which differ from one another only in the height of the raised portions on the disc of each cutter and therefore in the distance between the first and second planes. <IMAGE>

Title: Improvements in or relating to master clocks
Inventor: ATAMIAN HAGOP
IPC: G04G7/00
Filed: 1983-04-27
Abstract: Slave devices such as slave clocks, loudspeakers, buzzers and the like are controlled by means of a master clock having a plurality of output ports (P0 to P27) through which control pulses are supplied to the slave devices. An identity register (209) is associated with each port and has entered therein the pulse type to be transmitted through that port. A waveform generator (203) supplies different clock pulses in normal and fast rate pairs (C1 to C6). Waveform selector means severally associated with the individual ports (P0 to P27) is supplied with pulses from the waveform generator (203) and is arranged to pass only the pair of pulse trains (C1, C2 or C3, C4 or C5, C6) entered in the identity register (209). A counter (215) is arranged to be incremented by normal rate pulses from the waveform selector (216, 219). A gate (218) receives fast rate pulses from the waveform selector (216) and is enabled when slave device power (PE) is available and the state of counter (215) is positive, the gate 218 then decrements the counter (215) as output pulses occur with the result that until the state of the counter (215) is zero the gate (218) transmits output pulses in sympathy with the fast rate pulse train and thereafter transmits output pulses in sympathy with the slow rate pulse train. <IMAGE>
