Title: Improvements relating to the loading of natural silk
IPC: D06M11/20
Filed: 1930-09-30
Abstract: <PICT:0366513/IV/1> <PICT:0366513/IV/2> Natural silk is loaded without impairing its lustre by passing it without intermediate washing through a first treatment liquor containing a loading metal salt, e.g. a salt of tin or zirconium, one or more neutral salts of alkalies, ammonium, magnesium or organic amines, and phosphoric acid or phosphate salts, and a second treatment liquor containing an alkaline phosphate.  The second liquor may contain mild alkalies, preferably ammonia, or small quantities of free caustic alkali; organic nitrogen - containing weak basic compounds such as urea, thiourea, hydroxylamine, or hexamethylenetetramine may also be present. Protective colloids such as glue, gelatine, agar-agar, or decoctions of carragheen moss may also be present in either or both treatment liquors.  In an example the first liquor contains tin tetrachloride, disodium phosphate, phosphoric acid, and magnesium chloride and the second contains disodium phosphate, urea, and ammonia in specified proportions.  In the preferred apparatus the first treatment is effected in a trough 1, Fig. 1, provided with concentric smooth walls 2, 3 between which the folded debasted silk 16 is passed by means of conveyer bands 17, 18.  The silk passes thence between squeezing rollers 11, 12 past a suction device, if desired, and over rollers 30, Fig. 2, to the apparatus for applying the second treatment comprising an inclined conveyer band 24 moving upwards and sprayed with an ammoniacal phosphate solution from pipes 32.  The silk is carried thence by a band 24 moving downwards beneath other pipes 32 from which rinsing water is sprayed.  The two portions of the band 24 are provided with separate troughs 27, 28 for collecting the treatment liquors, and a third trough 25 is provided beneath the guide roller 21, and the collected liquors may be recirculated.  Alternatively superposed conveyer bands each provided with a collecting trough may be used, the upper bands being sprayed with the alkaline phosphate solution and the lower ones with the rinsing water.  The loaded silk may be subjected to the usual final treatment with a solution of water-glass.  Reference has been directed by the Comptroller to Specification 303,128, [Class 2 (ii), Cellulose &c.].

Abstract: High vacuum distillation apparatus comprises a plurality of chambers disposed in series for the continuous gravity flow therethrough of the liquid to be treated, one or more of the chambers being used for degassing the liquid before it is distilled, means for creating in the chambers a vacuum which increases from one chamber to the next in the direction of the flow, means for maintaining the interior of the chambers at temperatures increasing from the first chamber to the last, a rotary member mounted in each chamber to receive the inflowing liquid and project it on to a surrounding wall so that a thin and regular film of liquid flows down the wall, a heated surface positioned in the last chamber to receive the liquid from the relevant surrounding wall, a cooled surface for condensing the vapours disposed close to the heated surface, <PICT:0719563/III/1> and conduits provided with liquid-seals for the continuous withdrawal of distillate and distillation-residue from the last chamber.  In the apparatus shown, the liquid is degassed in chambers A1 and A2 which are separated by funnel 5 and liquid seal 6.  Discs 9 and 10, rotated by shaft 11, are disposed in chambers A1 and A2 respectively.  The cylinders 1, 2, bounding the chambers are heated by passing heating medium through jackets 14, 15; chamber A2 being maintained at a temperature higher than that of chamber A1. Chamber A1 is evacuated via pipe 17 to create a vacuum therein of the order of 1/10 mm. Hg.; and chamber A2 is evacuated via pipe 18 to create a vacuum therein of the order of 1/100 mm. Hg.  The liquid enters chamber A1 through pipe 20, and is projected by rotating disc 9 against the internal surface of heated cylinder 1 in the form of a thin film; and is thereby degassed.  The liquid then flows through seal 6 into chamber A2 where rotary disc 10 distributes it over the internal surface of cylinder 2.  The liquid which collects at the base of chamber A2 is entirely freed of gas.  The degassed liquid flows via pipe 22, liquid seal 23 and pipe 24 into distiller B.  The liquid is supplied to rotary disc 28, from which it is distributed over the internal surface of cylinder 27; it then flows over the external surface of cylindrospherical body 32, which is heated by circulating heating medium through pipes 36 and 37.  The interior of the distiller is evacuated to 10-3-10-4 mm. Hg. by a multi-stage pump attached to pipe 39.  The distilled vapours are condensed on cylinder 25 which is cooled by passing refrigerating medium through jacket 38.  A ring 40, for maintaining distillate and distillation-residue separate, is disposed between the body 32 and the cylinder 25 at the base of the distiller B.

Title: Improvements in internal combustion turbines
IPC: F02C1/00
Filed: 1931-10-30
Abstract: 384,753. Turbines. ROWLANDS, P. 0., Chester Road, Castle Bromwich, Birmingham. Oct. 30, 1931, No. 30059. [Class 110 (iii).] A turbine wheel 4 having buckets 56 is driven by liquid which is forced upon it by exploding gases in revolving combustion chambers 10. The chambers 10 are mounted in a frame 7 which is rotated by gearing 6 connected with the main shaft 3. Gas is fed in at 11 and passes by a channel 12 to a chamber 14 where it is mixed with air introduced through valve-controlled ports 16. Camactuated compression pumps 9 carried by the rotating frame 7 draw mixture past non-return valves 22, and force it through pipes 23 to the combustion chambers 10. Ignition is effected by a magneto 63 which is wired to sparking- plugs 53a through a distributer 65. For cooling purposes the combustion chambers have fins surrounded by water jackets. The inlet valves 24 of the combustion chambers 10 are normally kept closed by centrifugal force acting upon them, and upon pivoted weights 28, and are opened periodically by cams on rockshafts 33. The rock-shafts are actuated by cam and link gear 41, 44, 48. Should the speed become excessive, electromagnets 59 release latches 61 which lock the valve rods 41 and stop the machine. Each explosion chamber is surrounded by an annular space 35 which is bounded by a ported sleeve valve 36 controlled by the valve link 44. Water is fed by a pipe 38a to a rotary chamber 38 and passes through a port in the valve 36 into the space 35, and thence through ports 37 into the explosion chamber 10, where, under the action of centrifugal force, it compresses the already admitted charge of gas and air. Upon the charge being fired, the water is driven through the annulus 35 and the nozzle 54 to the turbine wheel 4. Movement of the valve 36 allows the spent gases to exhaust to a pipe 40a. Blades 8 are fitted to the frame 7 so that the air is carried round to prevent churning.

Patent GB-470089-A (GB)
Title: Improvements in brake arrangements for vehicles
IPC: B60T8/42
Filed: 1935-10-31
Abstract: 470,089. Fluid - pressure brakes. FELIES, J. F. Oct. 31, 1935, No. 30133. Void. Convention date, Nov. 3, 1934. [Class 103 (i)] Brake mechanism supplied with power dependent on speed of vehicle comprises brake cylinder relief valve having an orifice controlled by the power of the brake cylinder in such a way that after initial increase in the brake cylinder pressure the orifice is opened and the further brake cylinder pressure increase is modified by escape through the orifice, brake cylinder pressure then decreases so that the brake piston finally causes the orifice to be closed. In the modification shown in Fig. 1, when the brake pedal 1 is depressed a vacuum pump 7 is clutched to the vehicle transmission by a clutch 11 and draws air from the brake cylinder 21 connection of which with the atmosphere is closed by a valve 29 closed by depression of the brake pedal. Consequent movement of the brake piston 22 to apply the brakes moves a valve 34 which when the brakes are applied at full' speed moves sufficiently far to uncover an atmospheric outlet 39 so that the brake power is limited to 75 per cent of the maximum available. As the speed of the vehicle falls the vacuum maintained by the pump lessens and the brake piston moves towards release position. The orifice 39 is thus reclosed and the brake pressure increases again. The valve 34 reciprocates across the port 39 until the vehicle stops. In a modification using the vacuum of the vehicle engine induction pipe, this vacuum is regulated according to the speed of the vehicle by the clutch 11, which brings into operation a centrifugal governor operating a valve in the pipe between the induction pipe and the brake cylinder. A further modification shows the apparatus arranged for operation with a pressure pump and this arrangement may be modified by dispensing with the valve 34 and arranging the brake piston to control ports in the cylinder wall. In Fig. 8, a pressure pump 50 charges a reservoir 49 until the pressure therein operates a piston 60 to release the clutch 54 driving the pump. The pedal 1 controls a valve 75 in the pipe between the reservoir and the brake cylinder by a rod 3 which is operated after a certain amount of lost motion has been taken up by the pedal. The brake cylinder and the valve 34 are re-arranged for use with compressed air. In Fig. 10, liquid is circulated by a pump 7 through a pipe 9, the brake cylinder the valve 29, a pipe 28a, a container 8a and a return pipe 8 to the pump. Closure of the valve 29 applies the brake. In a further modification, the orifice 39 is contained in a sleeve movable by a hand lever so as to vary the brake operation. In a further modification, the sleeve is moved by a centrifugal governor driven by the vehicle transmission.
