Title: Improvements in transporters
IPC: B65G49/04
Filed: 1936-10-14
Abstract: 482,675. Screw-and-nut load-handling machines; elevated railways. MACKENZIE, W. E. Oct. 14, 1936, No. 27923. [Classes 78 (iii), 78 (iv), and 104 (ii)] In transporters comprising an endless overhead runway and carriers continuously moved thereon by a worm at a rate dependent on the pitch and speed of the worm, a second worm p, Fig. 1, extending parallel to part of the length of the first worm n and driven at a different speed, effects the propulsion of such of the carriers as are opposite to it. The driving means, according to the invention, are stated to be especially applicable to transporters as described in Specification 263,273, [Class 78 (iv)], wherein the carriers are provided with hoisting gear actuated by preceding and/or following carriers due to the differences in their rates of progression, thereby rendering them suitable for the transference of work through the several steps of a process, e.g. for electroplating articles, where it is necessary at times to move the work at a rate greater or less than'the maximum or minimum possible by a single worm. The carriers or trollies run in pairs b, c on an endless track a, the trolley c of each pair having a roller o engaging the worm n and pushing the trolley b before it through a projection 4. The load may be carried by suspenders h from a bridle k movable on rollers m up and down a T-shaped guide bar l depending from the trolley b, a hoisting rope f attached to the bridle passing over a pulley e on the trolley b and being attached at g to the other trolley c. Both trollies have rollers s to engage the second worm p. The thread of the worm n on the path g opposite the worm p may be omitted. The entrance and exit portions of the thread of the worm p are of shorter pitch than the intermediate portion to effect the raising and lowering of the suspenders h as they pass from one vat t to another. The worm p is driven from the worm n by gearing at each end such as at r, Fig. 3. The trollies are moved from one parallel portion of the runway to the other round a curved portion by transferring discs w having radial pins x which engage holes y in the trollies. The discs w are driven by worm-gearing z from shafts 1 connected by spiral gearing 3 to the worms n. The trollies have swivelling wheels d and. the rollers o, s have anti-friction bearings.

Title: Improvements in or relating to organosilicon compounds
IPC: C08G77/24
Filed: 1957-09-04
Abstract: The invention comprises fluoroalkylchloro silanes of the general formula <FORM:0812252/IV (a)/1> where n is 1 or 2, R is a saturated aliphatic or an aromatic hydrocarbon radical, m is 0, 1 or 2, and m + n is not greater than 3, and siloxanes produced by hydrolysis of these silanes.  The silanes are prepared by reacting 2-trifluoromethylpropane with silanes of the formula HnSiRmCl24-m-n, optionally in the presence of catalysts such as activated platinum on charcoal, and at 150-300 DEG  C.  The silanes are useful per se as water repellents for ceramics; and the siloxanes as lubricants or intermediates for the production of solvent resistant resins and rubbers.  The examples describe the preparation of 2 - trifluoromethylpropyl - methyldichloro-, trichloro -, dimethylchloro -, phenyldichloro-, octadecyldichloro - and xenyldichloro - silanes and bis - (2 - trifluoromethylpropyl) dichlorosilane; the cyclic trimer and tetramer and higher polymers of 2-trifluoromethylpropyl methylsiloxane, and the siloxanes (including disiloxane) prepared from the other silanes specified above.

Abstract: 1276144 Coating apparatus EASTMAN KODAK CO 3 June 1969 [3 June 1968] 27947/ 69 Heading B2L [Also in Division Dl] Coating apparatus comprises a hopper 10 having a horizontal narrow slit 11 from which liquid L flows onto a downwardly inclined surface 12 and which terminates in a lip 13 over which the liquid falls in a vertical curtain 27' onto an advancing substrate 29'. As shown, vertical curtain-edge guides and a movable curtain deflector 38 leading to a liquid recovery bath 37 may be provided. Optional deflector 32 prevents air draughts. The flow rate and substrate speed are controllable and the lipsubstrate distance may be adjustable. The edge guides may have a resilient brush or strip at their end which contacts the substrate.

Title: Improvements in or relating to removal of tar from the vapours arising from the distillation of wood
IPC: C10K1/04
Filed: 1921-10-21
Abstract: 170,591. Barbet et Fils et Cie., E. Oct. 21, 1920, [Convention date]. Addition to 120,560. Materials for purifying; condensing processes. -Wood gas &c. is treated for the removal of tar by washing in liquid tar and in condensates from a cooler through which the gases are passed after leaving the tar washer. The crude gases enter a washer A, of the kind described in the parent Specification, through a pipe a and pass at a temperature of about 100‹ C. to a condenser C in which dense vapours of tar, creosote oils, and acetic acid are condensed. The gases at a temperature of about 65‹ to 75‹ C. are then passed through coolers which condense the remainder of the volatiles. The liquid from the condenser C is returned by a pipe d to the upper part of the washer A and the methyl alcohol and acetic acid are re-vaporized from the tar, which is thereby freed from such impurities, a steam coil S immersed in the tar serving to complete the process before the tar is discharged through the overflow B. A sample of the liquid in the pipe d is drawn off through a cock Rand examined, the quality of this liquid being regulated by altering the temperature of the condenser C. The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification, in which the condenser C is worked, at a temperature of 30‹ to 40‹ C., so as to condense nearly all the vapours, and in this case about three-fourths of the condensed liquid would be drawn off from the cock R, only a small quantity thus being used for washing the vapours in the washer A. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to marine propulsion
IPC: B63H11/00
Filed: 1923-11-07
Abstract: 213,878. Paxton, C. M. April 7, 1923, [Convention date]. Lubricating; resistance to propulsion, reducing. - Water jet propulsion for ships comprises high velocity jets which in addition to the nozzle reaction are disposed in relation to the hull to induce surrounding water flow and tend to create a reduced pressure on the forward part of the hull and an increased pressure aft and thus assist propulsion. The orifice 6 of the nozzle 1 is a deep narrow slot parallel to the hull 2 directed slightly downwardly and outwardly at an angle of 14‹ and placed between onefifth to one-third of the length of the ship from the bow. The portion 6 may be detachable from the nozzle 1, and the slot form may be replaced by a vertical row of small circular orifices. The nozzle is carried by a plate 4 secured to the hull 2 and receives its supply at 3 from a centrifugal or other pump driven by a turbine or other prime mover. The intake is placed aft of the nozzles and at the keel line. Two or more sets of jets placed near each other may be employed, and another jet may be placed amidships. A screw propeller may be used in combination with the jets. A common header for the port and starboard nozzles mav be used when the cross section of the ship at the nozzle position is sufficiently small.

IPC: B29C70/00
Filed: 1955-10-08
Abstract: A pipe or other hollow article is moulded from reinforcing fibres and a synthetic resin, e.g. a polyester, phenol-formaldehyde, epoxy or furnace resin, by placing the reinforcement on an expansible mandrel, introducing the mandrel into a mould, impregnating the fibres with the resin before introduction into the mould, expanding the mandrel to force the fibres into engagement with the mould, and contracting and removing the mandrel either before or after the resin has been cured.  In a centrifugal process, the mandrel and reinforcement are introduced into a mould, and the mould rotated rapidly, the resin cured, and the mandrel removed before rotating the mould in which case the mandrel is either expanded to force the reinforcement against the mould or the inside of the mould is coated with a resin to act as an adhesive for the reinforcement. The mandrel may be (a) an inflatable rubber container, (b) a rubber cylinder having a screw threaded metal rod passing through a bore in the container and having a nut at each end for expanding or contracting the container or (c) a split cylinder provided with a longitudinally movable tapered plug. The reinforcing fibres may be of glass, nylon or sisal and may be in the form of a nap, spirally wound strip or loose roving. Specification 771,833 is referred to.
