Title: Improvements relating to revolving doors
IPC: E06B3/90
Filed: 1922-06-07
Abstract: 195,305. Colman, T. B. June 7, 1922. Revolving doors, such as described in Specifications 22552/10, 10589/12, and 187,740, are provided with means to ensure rotation in one direction' only. For this purpose, one member 4 of a clutch is secured above the soffit, and the second member 6 is slidable on a sleeve 2 which rotates with the door. During rotation of the door in one direction, the clutch members are separated by pins 9 carried by the sleeve and entering inclined slots in the member 6; on rotation in the reverse direction, the clutch members are forced into engagement by wedge-shaped projections on a collar 11 keyed to the sleeve. Adjustablypressed pads 15 act on the clutch member 6 to hold it against rotation. The pins 9 and the inclined slots may be omitted. Spring-pressed pawls may be mounted in the soffit to engage the wings on reverse rotation in place of or in addition to the clutch; or pawls on the wings may be adapted to engage a ratchet on the soffit or circumference of the casing. In the case of doors used for entrance or exit only, obstructions to prevent access to the door on one side are combined with the devices described above. These are preferably quadrant-shaped members 26 and are fixed on the stationary central shaft, slits being provided in the door wings to pass over same when rotating. Rubber &c. draught-excluding strips are secured in the slits and to the tips of the wings. The clutch may be faced with leather to avoid noise. In the case of a movable door with collapsable wings, the clutch member 4 is secured to the trolley which carries the central rotating spindle.

Title: Improvements in or relating to a method for the purification of titanium tetrachloride
IPC: C01G23/02
Filed: 1953-06-10
Abstract: Crude titanium tetrachloride is treated to remove a major portion of the impurities therein by refluxing in the presence of a non-drying vegetable oil of the olive oil type, namely almond, apricot kernel, date kernel, hazel nut, peach kernel, peanut, plum kernel. and olive oils.  The amount of oil employed is suitably 0.1 to 0.2 per cent. The treatment may suitably be carried out in a unit comprising a still having a fractionating column, a reflux return and a condenser and the tetrachloride oil mixture may be heated to a temperature and for a period of time such that all the tetrachloride as vapour is circulating through the fractionating column and reflux return; thereafter the vapour is allowed to pass to a condenser where the tetrachloride is condensed and collected leaving a hard granular still residue comprising rutile, anatase, free carbon and vanadium in the form of its chloride or oxychloride, which may be recovered from the residue by water leaching.  Impurities referred to include vanadium, silica, alumina, niobium and tungsten and the vanadium content of the final condensate may be reduced to from 0.0001 to 0.0003 per cent by weight of the tetrachloride.  Examples relate to the addition of 1 part of olive or peanut oil respectively to 1000 parts of crude tetrachloride at room temperature and the subsequent refluxing of the mixture at 136 DEG C. for about 2 hours, followed by distillation to obtain water-white titanium tetrachloride condensate.

Filed: 1943-09-30
Abstract: 570,757. Counting-apparatus. BAKER, D. A. Sept. 30,1943, No. 16038. [Class 106 (i)] A machine for counting and delivering seeds or other small articles comprises a box in which the seeds or articles are placed in bulk, a set of vertical plungers passing up through the box, means by which the box is raised and lowered in relation to the plungers to locate a seed on each plunger, and means whereby the seeds are removed from the plungers and delivered into a package. As shown in Figs. 1 and 2, a seed box D supported at its end by plates J, connected by tie rods M, is guided by blocks d slidable on pillars a to reciprocate vertically by means of a connecting rod K and crank-pin disc H operated by gearing from a motor G. Extending upward through the bottom of the box is a set of plungers F each having a cupped end to receive a single seed. When the box is lowered after raising, the plungers F extend through a gap in the slanting upper wall d<4> of the box and a rod N carrying a brush or bristles n is rocked to sweep the seeds into a hopper E tapering into a spout e<2> from which the seed are delivered. The rod N is mounted in eccentric bearings for adjustment purposes and its movement is controlled by a spring lever n<1> co-operating with a byepass pawl p supported on a pillar P. To render a plunger inoperative, a rounded cap may be placed on top to prevent pick up of a seed. For different sized seed or other articles, a cap with a larger cupped end may be fitted on the plungers.

Filed: 1926-06-25
Abstract: 277,758. Telegraph Construction & Maintenance Co., Ltd., and Riddle, J. June 25, 1926. Perforated-strip transmitters.-In a perforatedstrip transmitter the contacts are made through the signal perforations as the strip passes between one or more rollers or other conductive surfaces and conductive balls or plungers biassed outwards from recesses in a rotary disc. Two such discs 1, 2, Figs. 1 and 3, each provided with balls 6 pressed outwards by springs 7 in radial recesses 5, Fig. 2, and each co-operating with a corresponding conductive roller 8, may be connected by a wheel 3 of insulating material provided with teeth for engaging the feed perforations in the strip which is held against the wheel by an adjusable guide 11, Fig. 2. The outer ends of the recesses 7 are of a diameter to retain the balls. Each roller 8, preferably grooved to the curvature of the balls, is carried by a flexible arm 15 projecting from a bracket 25 and adjustable to or from the disc 1 or 2 by a set screw 17 mounted in a rigid arm 16, and a screw 18 is provided for locking the screw 17 in adjusted position. Curbing at transmitter; automatic telegraphs.- The transmission circuit for the apparatus shown in Fig. 1 includes a curbing disc 19 of insulating material carried by the shaft of the discs 1, 2 and provided with embedded metal strips 20 radiating from a metallic hub 21 as shown in Fig. 4. A contact brush 24 bears continuously on the hub 21 and a second brush 22 is adjustable radially of the disc to vary the degree the curbing. Alternatively the curbing may be effected by a brush with two adjustably-spaced conductivelyconnected portions bearing on contact bars separated by insulation to constitute a rotary commutator. The impulses produced by each disc 1 or 2 may be applied to the field winding of a corresponding generator of which the armature is connected to line and earth or they may be applied to the winding of a relay which closes contacts for transmission to line. Fig. 7 shows a modified construction of the curbing disc 19 and its circuit connections in which the outer portion of the disc is made conductive with radial tapering portions extending into the spaces between the strips 20, and a third brush 22a bears on this outer portion. The arrangement is such that the line L is earthed through the contacts 22, 22<a> for a portion of each signal determined by the radial position of the brush 22.

Title: Improvements in, and relating to, the manufacture and production of artificial threads, filaments and the like
IPC: D01F2/30
Filed: 1930-05-26
Abstract: In the downward dry spinning of artificial threads, filaments, &c., the whole of the evaporative atmosphere is introduced into the cell or chamber at the region of and on one side of the extrusion nozzle, while the atmosphere is withdrawn either wholly or partly on the opposite side of the cell, so as to cause the atmosphere to move across the face of the nozzle.  When the whole of the atmosphere is withdrawn at the region of the nozzle, the cell or chamber may be comparatively short, say, of one foot in height; if, however, a part only of the atmosphere is withdrawn at this point, then the remainder is caused to pass downwards with the filaments, and is withdrawn at a point or points lower down the cell, and in this case the cell may be several feet in height. To assist in causing the atmosphere to move across the face of the nozzle, a small horizontal baffle may be provided just below the point at which the atmosphere enters.
