Title: Improvements in the manufacture of decolourising carbon
IPC: C01B32/336
Filed: 1923-08-09
Abstract: 228,812. Potts, H. E., (Algemeene Norit Maatschappij). Aug. 9, 1923. Carbon and charcoal.-Active carbon is produced by subjecting carbonaceous material, for example wood or fruit pips, to the action of activating gases while freely moving in close proximity to heat-radiating surfaces supplementary to the ordinary walls of the retort. The use of rotary retorts is excluded. The heat radiating surfaces may consist of baflle rods, which, the Provisional Specifications state, may be transversely disposed in staggered horizontal layers and may be composed of silica, fireclay or magnesia heated to the activation temperature, or may be hollow and internally heated. In the apparatus illustrated, the heat radiating surfaces consist of a number of superimposed hollow rhomboids 22 heated by flue pipes 25 and disposed within an activating chamber 20 provided with inlets 26, 26<1> for activating gas and inlets 27, 27<1> for the combustible gas mixture for internal heating. The raw material fed from a hopper 21 is forced to move in thin layers past the rhomboids by the provision of baffles 23, 28 and is finally discharged into the chamber 24. The gases are drawn off by an exhauster 30 through a conduit 29 and dust collector 31. The nature of the raw material, which should be finely divided, the temperature and the quantity, quality and velocity of the gases may be adjusted so as to yield novel products of very high activity, which according to the Provisional Specifications may be used for catalytic reactions, gas absorption, and for the purification and sterilization of sugar juices, water, oils such as linseed and soya bean oils, fats and other liquids, and may be easily regenerated by burning or treatment with acids, alkalies &c. in tne Provisional Specifications peat and predistilled material such as charcoal and peat coke are described as suitable initial materials, steam, carbon dioxide, air, producer gas, water gas, Mond gas, chlorine, sulphur dioxide, volatile chlorides, ammonia &c. as suitable activating gases and lumps of quartz and the like as heat radiating surfaces.

Title: Titanium halides
Inventor: EMELIUS HARRY JULIUS
IPC: C08F4/64
Filed: 1962-07-13
Abstract: Propylene is polymerized using the following catalyst mixtures containing a lower titanium halide and an aluminium halide excluding fluorides at 50 DEG  C.: Example 1, 17.8 millimoles Et3Al and equivalent of 8.9 millimoles Ti of a reacted mixture prepared from 9 gms. Al powder, 121 mls. TiCl4 and 8.12 gms. ICl; Example 2, 20.8 millimoles Et3Al and equivalent of 10.4 millimoles titanium of a reacted mixture prepared from 9 gms. Al powder, 121 mls. TiCl4 and 33 gms. ICl; Example 3, 21.0 millimoles Et3Al, and 10.5 millimoles titanium equivalents from reacting 9 gms. Al, 330 mls. TiCl4 and 33 gms. ICl; Example 4, 20.7 millimoles Et3Al and 10.35 millimole titanium equivalents from reacting 9 gms. Al, 121 mls. TiCl4 and 10 gms. ICl3.ALSO:A mixture containing a lower halide of titanium and an aluminium halide, other than the fluorides, which can be used in the vapour phase oxidation of a titanium tetrahalide, is produced by reducing a titanium tetrahalide (e.g. TiCl4) other than the fluoride with aluminium in the presence of an interhalogen compound having the formula ABx, where A and B are different halogens, neither being a fluorine atom, and X is an integer from 1-3 inclusive (e.g. ICl or ICl3).  Preferably only sufficient ABx is used to initiate the reaction, e.g. 0.9-10 times the weight of aluminium used.  The tetrahalide is preferably at least sufficient to react with all the aluminium present.  The process may be carried out in a liquid diluent, e.g. aromatic hydrocarbon (e.g. benzene, toluene or xylene) or excess titanium halide if a liquid (e.g. TiCl4).  The reaction, which may be started by heating, and the recovery of product, is preferably carried out in absence of oxygen and moisture e.g. under nitrogen or argon.  The interhalogen compound may be introduced by dissolving it in the titanium tetrahalide or liquid diluent, e.g. before adding this to the aluminium, or adding it after mixing the rest of the reactants.  The Al is preferably finely divided. Examples are given.  The vapour phase oxidation of a titanium tetrahalide can be carried out by reacting a calculated proportion of aluminium with an excess of titanium tetrahalide in the presence of the interhalogen compound ABx, and using the product as a feed or as an addition to the feed to the vapour phase oxidation reactor.ALSO:A catalyst comprises a lower titanium halide and an aluminium halide (other than the fluorides), and triethyl aluminium, tri-n-propyl aluminium, tri-n-butyl aluminium or triphenyl aluminium, or alkyl or aryl compounds of other Group I-III metals.

Title: Improvements in or relating to lift controlling mechanisms
IPC: B66B1/16
Filed: 1933-10-05
Abstract: 426,492. Lifts. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, SMART, N. C., and MOSS, B. F., c/o General Electric Co., Stoke, Coventry. Oct. 5, 1933, No. 27376. [Class 78 (ii)] [See also Group XXXVIII] Electric plant.-A floor-selector for a pushbutton lift controlling system comprises a group of two-position relays which are successively tripped over by impulses transmitted from the lift as it passes successive floors, and which remain in either position without the continuous use of current. In the diagram, the relays are shown at FA-FF, and the lift is at the ground floor. Upon operating the third floor push-button PC, for example, contactor CC is energized, locks at cc1, and opens at cc2, cc3 a short circuit across the "up" motor contactor. As the lift passes a suitable point between each floor, an indicator plate NS operates ns1 momentarily to transmit an impulse via up4 and b2 to one of relays FA-FF, whose successive operation is ensured by contacts fa1, fb1, &c., and contacts b2 of relay B. When relay FB is impulsed, contacts fb3 operate a slow-down relay SD via cc3, which releases CC at sd2, so that cc3 restores the short-circuit across the " up contactor via fb3. The lift is brought to rest at each floor by the opening of contacts nr1 by an indicator plate NR, SD locks via contacts sd1 and a time-delay circuit so as to keep sd2 open for a period sufficient to permit opening of the gates ; gate switches FM are provided at each floor and prevent operation of the motor contactors. unless the gates are all closed. For downward travel of the lift, similar operation of relays FA-FF occurs via contacts dn4 and ff 1 fd2 &c. Relays FA-FF may be of the type described in Specification 354,847, [Group XXXVII], or of the latching type. Specification 423,805, [Croup XXXVII], also is referred to.

Patent GB-275451-A (GB)
Abstract: 275,451. Huber, H. Nov. 5, 1926. Printing totals and reading totals. The result of a calculation as represented by the rotary displacement of the wheels of a totalizer, having tiansfer-mechanism of the continuous-gear type peimitting simultaneous actuation and transfer, is rendered visible by rotating certain denominational wheels seriatim into initial or standard positions so as to throw the result into indicating or printing elements displaying the digits in a straight line. In the application of the invention to a multiplying-machine (Figs. 1 and 3) the externally and internally toothed wheels c receive the denominational actuations through pinions q and are engaged by the planetary pinions i carried by gear wheels g and meshing also with pinions d internal with spur-wheels f. Upon a shaft b are sleeves l each rigidly supporting a wheel m meshing with wheel f, a wheel k gearing with wheel g and a star wheel n. The various wheels n are thus subject to the ordinary actuations derived from pinions q through wheels c, i, g and k, and also continuously receive transfers from the lower denomination through wheels m, f, d, i, g and k. In order to take a reading of the total, a shaft o is given one rotation so as through spirally disposed arms p to turn the star wheels n back into initial or standard position, one after the other commencing with the lowest denomination. During the rotation of the shafts o, numeral wheels 10 carried by arms 5 controlled by notched discs 15 are engaged with wheels c and thus receive the return movements of the star wheels so as to exhibit the total. Figs. 4 and 5 show the invention as applied to an adding and subtracting machine operated by the depression of keys 22 which differentially displace spring-controlled bars 21 linked to levers 24 carrying actuating pawls 25 engaging the wheels c. Oppositely effective detents 31, 32 are controlled by a release key so that when the item has been set up the depression of this key frees the wheels c to allow actuation by the restoration of the bars 21. When it is desired to take the total, the shaft o is rotated as in the first form and this causes arms 29 to bear upon the pawls 25 to lock the levers 24 to the wheels c so that by the return of wheels n and consequent rotation of wheels c the item-indicating plates 27 are positioned to expose the total at the window 36. The arms 29 may be given an intermediate position to free the pawls 25 entirely from the wheels c so that the levers 24 and plates 27 may return to normal position without affecting the totalizer. By further adjustments the arms 29 may cause engagement of the actuating pawls during their up strokes only, thus enabling subtraction to be effected. Moreover by maintaining the detents 31, 32 respectively out of and in engagement the keys may be depressed in rapid succession for effecting repeated addition.

Abstract: 649,776. Knitting. QUORTEX, Ltd., and CHAPMAN, J. H. Oct. 15, 1947, No. 27601. [Class 74 (ii)] A method of forming heel parts of a stocking blank consists, whilst continuing to knit on the instep needles, in first progressively widening the blank by loop transference, initially on a comparatively large group of needles extending inwardly from the normal selvedge and thereafter on groups of needles of substantially the same size but located at progressively increasing distances outwardly from the inner end of the first group then, after said widening, progressively narrowing the blank by loop transference on a comparatively small group of needles extending inwardly from the selvedge of the last widened course and, during said narrowing, forming marking stitches (e.g. eyelet holes along lines B, C ; B<SP>1</SP>, Cl) by needles at the junction of that large group of needles last to be employed during widening and the remaining needles. The widening produces panels A, B, D, F ; A<SP>1</SP>, B<SP>1</SP>, D<SP>1</SP> Fl and rows of eyelet holes A, B ; A<SP>1</SP>, B<SP>1</SP>. The number of needles narrowing is progressively reduced, by outwardly rocking the narrowing boxes one needle per course until all the needles of the group have been stripped, the final narrowing course coinciding substantially with the last course of the heel proper. Thereafter, the thread carrier is racked in to G, G<SP>1</SP> and, during formation of the foot panel 3, ravelling courses 4 are knitted. After removal of the ravelling courses, the ends G, E and G<SP>1</SP>, El of the heel parts are linked together and the stocking is completed in the normal way.
