Title: Improvements in or relating to the manufacture of coke
IPC: C10B49/04
Filed: 1969-11-28
Abstract: 1,271,585. Continuous carbonizing apparatus. KOPPERS CO. Inc. 28 Nov., 1969 [12 Dec., 1968], No. 58410/69. Heading F4B. Apparatus for continuously coking coal comprises an endless conveyer 13 fed by a coal hopper 61, heating walls 15 around a coking chamber 45, and a discharge hopper 17 incorporating cooling water sprays 100 and a rotary pocketed drum 89 feeding a discharge conveyer 91. The conveyer 13 comprises endless chains 23 carried by sprockets 25 and attached to refractory blocks 21 with side-plates 31. The heating walls are formed by inner and outer walls 39, 43, 41 and 47 and hot gases from burners 81 are directed therethrough along a sinuous path defined by side baffles 53 and upper baffles 57 before leaving via a hood 59 and chimney 19. The burners 81 are disposed in a header wall 79 connected by a branch 95 to a conduit 93 in the discharge hopper 17, the top of conduit 93 having a butterfly valve 97. Once coking has started, some of the gas generated in chamber 45 goes direct to the burners 81 and some into the hopper 17 where it passes up conduit 93 together with steam generated therein from the cooling coke. Windbores 33 below the conveyer supply limited quantities of air or oxygen enriched air to chamber 45. The coal hopper 61 may be equipped with superposed reciprocating rams (Figs. 6 and 7) which discharge the coal down a slope on to the endless conveyer 13 with some consequent compression. Modified apparatus (Figs. 3-5) has double concentric heating walls, the inner one being fired by side burners for part of the cycle and swept by a stream of carbonized gas and steam for the remainder of the cycle. Reforming action which takes place cools the heating wall to a desired minimum temperature.

Title: A portable auxiliary fastening device
Inventor: WEINGART RICHARD ISAAC NEWTON
IPC: E05C19/18
Filed: 1967-12-29
Abstract: 1,222,960. Releasable fastenings. R. I. N. WEINGART. 29 Dec., 1967 [23 June, 1967], No. 58975/67. Heading E2A. A portable auxiliary fastening device of a door comprises a fastening bar 10 having a long thin flat portion with protrusions along at least one of the two opposed longitudinal edges thereof and provided with a laterally offset anchor 14 such that the fastening bar can be arranged to extend forwardly between a frame and a door or drawer when the latter is in its closed position with said anchor engaging a part of the frame to secure the bar against forward displacement, a collar 26 having an axial bore 28 with at least one radially extending groove 30 to enable said collar to be slid over said bar to a position adjacent a front face of the door or drawer and the frame, and having recess formations 29 in said bore communicating with said groove or grooves whereby the collar is adapted to be rotated to locate some of said protrusions in said recess formations to secure the collar against axial movement along said bar, the device having means adapted to receive releasable locking means to prevent rotation of said collar after said protrusions have been engaged with said recess formations. In the construction shown the bar has protrusions 11, 12 along both edges and the collar has one groove only, the mass formations being portions of a screw thread in the bore. The releasable locking means as a padlock and the means which it engages is a pin which spans or a notch 32 in the collar. In a modification, the collar is circular instead of being hexagonal as shown, it has two grooves 30 and the means engaged by the padlock is a curved lever product on a pin so that it extends through a notch similar to the notch 32 so that one end engages the bar, the opposite end portion having a hole for the padlock which limits its rotation so that the bar cannot be aligned with the grooves 30.

Title: Feeder for copying machines
IPC: B65H3/44
Filed: 1979-03-09
Abstract: A high capacity paper magazine (110) which can be used with an existing photocopier in place of the standard magazine comprises a paper supporting plate (158) biased upwardly by springs (138). The plate is mounted on a parallel motion mechanism formed by arms (144, 152) which carry meshing gears and upward motion of the plate (158) is damped by a flywheel (220) which is rotated as the plate rises. Normally, when the top sheet of paper is at the desired height, the upward movement of the plate (158) is prevented by a brake (236). However, as paper is removed, downward movement of paper feed rollers (320) releases the brake to allow the paper to be lifted by the springs (138). Both the brake and the flywheel incorporate clutches so that during loading the plate (158) can be depressed without opposition from the brake or flywheel. <IMAGE>

Title: Low-pressure mercury-vapour discharge lamp
IPC: H01J61/20
Filed: 1979-05-11
Abstract: A low pressure mercury-vapour discharge lamp includes a quantity of a binary amalgam so disposed that, during operation, it is heated to provide a suitable mercury vapour pressure. The amalgam consists of mercury and magnesium in the form of any one member (except the last) of, or an alloy of any two adjacent members of the series HgMg, Hg3Mg5, HgMg2, Hg2Mg5, HgMg3, Mg. The amalgam is chosen so that anticipated loss of mercury from it during construction and/or operation of the lap lamp will not change it qualitatively, and hence the vapour pressure of mercury will be maintained. A3:1 alloy (the mercury-richer component predominating) is preferred to provide manufacturing tolerance. The amalgam may be a sheet-metal element disposed on a mounting plate adjacent an electrode, the construction and arrangement of the element, plate and electrode determining the temperature attained by the amalgam.

Patent GB-2037845-A (GB)
Title: Aqueous polymer solutions for well treating methods
IPC: C09K8/88
Filed: 1979-09-26
Abstract: Processes and compositions for use in these processes, are provided whereby the fluid flow and surface characteristics of porous permeable particulate formations, especially subterranean formations intersected by an oil well, can be altered. The compositions can be used to increase viscosity or gel aqueous fluids, especially acids, which can be used to treat such earthen formations. Treatment of the earthen formations with the compositions of this invention can substantially modify the permeability and surface characteristics of the formation to prevent or reduce the flow of aqueous fluids, especially water and formation brines through that portion of the formation, thereby reducing the water-oil ratio of fluid flowing through or produced from that formation and in some cases enhancing the hydrocarbon production. The invention uses branched organic polymers of a wide molecular weight range. The branches are preferably hydrophilic and the polymer contains bonding groups (e.g. ionic bonding groups) which serve to attract or repel a substrate, a particular formation, suspended solids, other polymers or segments, carrier fluid or a fluid to be treated.
