Title: Improvements in or relating to pressing machines for molten material
IPC: C03B11/00
Filed: 1945-01-03
Abstract: 588,632. Moulding-machines. SISSON, J. B. Jan. 3, 1945, No. 239. [Class 87 (ii)] [Also in Group XXIII] An apparatus for moulding a large number of articles which may be alike, complementary or dissimilar, from molten material such as glass comprises an intermittently rotated drum having its surface covered with removable axiallyarranged lines of moulds 66 forming annuli around the drum, all the moulds in one axial line being filled with gobs of glass, by means not shown, whilst the drum is stationary. A second drum 37 having a similarly arranged and similar number of co-operating press members 83 is rotated, out of contact with the first drum, step by step in phase with the first drum. During the time that neither drum has any motion of rotation the second drum is swung into contact with the first so that the press members 83 in one line co-act with the filled moulds at the station adjacent the filling point and is then swung away before rotation starts again. Cooling takes place at a third station and ejection by means of a sliding plunger 72 acted on by a weighted cam 77, occurs at a fourth station. Fluid jets, e.g., for cooling, cleaning or lubricating, may be directed on to the moulds at the station preceding the filling station and on to the press members at the station preceding the pressing station.

Filed: 1937-01-07
Abstract: 472,874. Wrapping-machines. VERPACKUNGS-AUTOMATEN GES., and WOLTER, F. Jan. 7, 1937, No. 448. [Class 94 (i)] The machine wraps regular articles or irregular articles such as cigars, tooth brushes, sweets, &c. The wrapping material is drawn from a drum 1 past a roller 3, and a guide channel 4, which forms it into a U-shape in cross-section within the channel. Articles 6 are introduced into the paper trough by a feeder 8, and the paper is folded over at the top to form a tube. The tube passes through a ring-shaped member 10, Fig. 3, consisting of a metal core having a helical spring 10b loosely wound on it. The spring bears upon the wrapper and causes it to conform to the shape of the articles. Heating members 9, 9a advance and press the longitudinal seam and the space between the articles respectively, causing the formation shown at x, Fig. 6. Prior to the action of the members 9, folders pass through slot 13a in the channel to tuck in the sides of the wrapper to facilitate the formation of bellows folds. The heating elements are withdrawn and grippers 2, Figs. la and 7, advance and seize the flattened sleeve portion, and draw it to the right. The jaws 2a of the grippers are formed with teeth 15 and grooves 16 to form transverse indentations 17, and a cutter 20 forms a longitudinal slot 17a, by which means the ends of the sleeve are formed in two parts to facilitate tearing open. Shears 21 sever the sleeve into separate packets and the end pieces may be folded on to the ends.

Direct air-pressure apparatus, automatic; floats; valves for pressure fluid, actuation of.- Relates to systems of the kind described in Specifications 144,688, [Class 47 (ii), Fire-extinguishing &c.], 153,587, 154,595, [Class 47 (ii), Fire-extinguishing &c.], 154,891, 166,551, and 172,329, comprising a storage, reservoir 1, Fig. 3, and two alternately-acting auxiliary receptacles 2<a>, 2<b> through which the liquid passes to the discharge pipe 14. The discharge of the auxiliary receptacles 2<a>, 2<b> is controlled by an automatic reversing-device, and is effected by protective gas in a closed pipe circuit comprising a high-pressure gas tank 6 and a low-pressure gas tank 8, with an interposed compressor 11 operated at will by hand or by automatic or non- automatic mechanical means. The liquid is fed from the reservoir 1 to the receptacles 2a, 2b either by gravity, or, if at a higher level, by sucticn from the low-pressure tank 8. A multiple system for delivery at a number of points may be employed, the auxiliary receptacles 2<a>, 2b being arranged in pairs connected in parallel to a double pipe line from central high and low pressure gas tanks. As each receptacle 2a or 2<b>, Fig. 3, is emptied by means of gas acting through a pipe 4 and branch pipes 4a or 4<b>, the gas pressure is transferred to the companion receptacle by an automatic reversing-device 16, shown diagramatically in Fig. 7. The receptacles 2a, 2<b> are provided with floats 51 (of cup form fitted with emptying-siphons), each adapted in its lowest position to close a gas-inlet valve 50, whereby the gas pressure is transferred to a diaphragm 28 or 29, through a needle-valve 43 controlled by an auxiliary diaphragm 41 or 42 in communication with the discharge pipe 14. Operation of the diaphragm 28 or 29 causes the operation of valves 39, 40, through lever mechanism, to transfer the gas pressure to the receptacle 2<a> or 2<b> next to be emptied. The pipe 14<1> connecting the delivery pipe 14 with the reversing- device may be fitted at its junction with the pipe 14, with a receptacle adapted to regulate the. discharge of liquid. The high and low pressure tanks 6, 8 are connected together by a pipe 12 fitted with a valve 13 adapted when opened to restore the tanks 6, 8 to atmospheric pressure during periods when the plant is inoperative.

Title: Improvements in cathodes and method of making them
IPC: H01J1/28
Filed: 1952-01-07
Abstract: 721,837. Cathode materials and processing. EGYESULT IZZOLAMPA ES VILLAMOSSAGI R. T. Jan. 7, 1952 [Jan. 11, 1951], No. 483/52. Class 39(1) The type of cathode described in Specification 715,284, which consists of a closed box having one wall of sintered porous tungsten through which diffuses caesium and/or rubidium vapour from a source within the box, is improved by having oxides of the active metal and of tungsten present between the sintered tungsten surface and the active layer thereon. The sintered member is oxidized by heating to about 600-800‹ C., in an atmosphere of nitrogen containing about .1 per cent. of oxygen. This forms the so-called " blue " oxides of tungsten, the most important of which is W,O,. The oxide layer is partially reduced by the active metal as it diffuses out. The reduced tungsten is in a finely pulverulent state, in which the partially oxidized active metal is embedded; the active metal is present in the outer surface of the oxide layer. Applications mentioned are to fluorescent, flash and stroboscopic lamps, or co'd cathode thyratrons. A suitable source of caesium is caesium chloride reduced by sodium. The cathode may be blackened, and have cooling fins.

Title: Improvements in the chromium-plating of needles
IPC: C25D7/00
Filed: 1933-01-06
Abstract: 412,641. Electroplating. HORST, H. VAN DER, 22, Alexanderlaan, Hilversum, Holland. Jan. 6, 1933, Nos. 565 and 9039. [Class 41.] The pointed ends of metal articles such as gramophone needles are prepared for chromium-plating by anodic etching in an acid bath. During the subsequent plating the average current density over the whole surface to be plated is maintained at a constant value lying between 16 and 25 amps. per sq. dcm. ; the bath temperature is maintained at 53 C. for the lower current density value and at 65 C. for the higher value, and correspondingly for intermediate values. The anodes are arranged in such a way that the current density at the tips of the articles lies between 30 and 60 amps. per sq. dcm. ; the current density at the tips is estimated by the thickness of the deposit there in relation to the average thickness. The preliminary etching may be continued until the depth of metal removed from the points is substantially the same as that to be deposited. By etching for a suitable time all the needles of a batch mounted in the same holder may be etched to the same degree of sharpness. A holder for gramophone needles comprises a pair of plates 10, 11, Fig. 3, hinged at 12. The needles 13 are held between a rubber strip 17 and a copper strip 18 which are forced into engagement by a cam 15 operated by a handle 16. The engaging faces may be grooved. The anodes consist of lead or mild steel wires 24 disposed some distance above the points of the needles. The wires are anchored at one end and at the other end are slidably mounted in a grooved plate 32 secured to the underside of a block 25, provided with a curved surface 33 round which the wires are bent upwardly. The upward limbs are passed through an abutment bar 29 and maintained taut by a spring 30. The blocks 25 are mounted on guide bars 26 by clamps 28. The plates 11 of the holders are provided with lugs 19 engaging slots in conducting supporting bars 21.

Title: Improvements in or relating to a cable railway for circulation service
IPC: B61J1/06
Filed: 1951-01-09
Abstract: 691,812. Rope railways; terminals for overhead ways. PETER, K. Jan. 9, 1951. [Jan. 19, 1950] No. 645/51. Classes 78 (iv) and 104 (ii). A circulating cable railway has the suspended cabin transferred from the arrival side of the support rope to the departure side of the support rope at the location where the horizontally disposed pulley for the reversing turn of the haulage rope is situated, the means by which the transfer is effected comprising a short rail carried by a member 7 independently rotatable around the axis of the pulley and on to which short rail the support trolley of the cabin runs, the short rail member thereafter being turned around the axis of the pulley by the action of the haulage rope which is of course connected to the support trolley of the cabin. The support ropes 4, 10 terminate in rails 5, 9 adjacent the pulley 2 and the support trolley 12 is attached to the haulage rope 3 by means of a universal coupling 17. The rail 13 of the member 7 normally abuts the arrival side rail 5 and the supporting trolley 12 on rolling from the rail 5 to the rail 13 depresses a catch 20 to lock the rails 5 and 13 in alignment. The member 7 is rotated by the haulage rope 3 through a roller 19 of the support trolley 12 engaging a spring loaded catch 15. The force exerted by the rope 3 on the roller 19 of the trolley 12 when the rail 13 abuts the departure side rail 9 is sufficient to depress the catch 15 to lock the rails 13, 9 in alignment and the trolley 12 is then pulled on to the rail 9. The member 7 is returned to its normal position by a spring or weight acting on a rope, Fig. 8 (not shown), wound round a hub 11. The doors of the cabin 1 may be opened or closed by hand but normally when the cabin 1 is occupied they are opened just before the cabin enters a station by a stop actuating a valve 26, the weight of the passengers opening another valve in a duct of an hydraulic system to supply oil under pressure to a cylinder 27, and they are closed by a spring or if the system is fully automatic by hydraulic pressure acting on the opposite side of the piston in cylinder 27 after a certain time delay. The oil is maintained under pressure in a reservoir by a piston pump 23 driven by a crank 24 connected'to a roller 34 of the trolley 12. A catch 22 mounted on a rib 21 of the hub 11 is lifted by an oblique portion of the trolley 12 to engage a projection thereon to hold the trolley 12 in position on the rail 13.

Title: Improvements in or relating to folding photographic cameras
IPC: G03B3/02
Filed: 1937-01-11
Abstract: 488,578. Photographic cameras. KODAK, Ltd. Jan. 11, 1937, No. 781. Convention date, Jan. 15, 1936. [Class 98 (i)] Latch devices for both the front and the bed of a folding camera are released from operative position by the operation of the focusing member of the camera. The camera bed 4 is hinged on a pintle 7 to the body 1, and the lens board 12 is supported by lazy-tongs 13 which are attached both at pivots 15 and at studs 16 which slide in slots 17 in the lens board 12. Each stud 16 also supports a link 18 which is pivotally attached at 19 to the bed 4. One latch device comprises a pivoted lever 31 which is pressed by a spring 32 so that a shoulder 33 lies over a lug 34 on the link 18. When the focusing ring is moved clockwise, a lug 36 strikes a flange 37 on the lever 31 and moves it to the unlatched position. The second latch member comprises a flange 38 on the lens board 12 provided with an aperture 39 for receiving a pin 40 carried by a leaf spring 41 on the link 18. As the camera is opened, the pin 40 rides over the flange 38 and drops into the aperture 39. When the focusing handle 26 is moved clockwise, to a position beyond that for infinity focusing, a straight edge 45 on the ring 25 strikes a flange 44 on the spring 41 and moves the pin out of the latching position. As the camera is folded, an extension 47 on the lazy-tong member 13 moves the focusing ring to the infinity position. A latch member 50 with pin 51 and slot 52 locks the camera in folded position. Specification 471,541 is referred to.
Patent GB-569212-A (GB)
Title: Improvements in and relating to the manufacture and production of artificial filaments, threads, films and the like
IPC: D01F9/04
Filed: 1942-01-20
Abstract: Artificial filaments, threads, films and the like are obtained by extruding into a liquid or gaseous setting medium an aqueous solution of an alkali metal alginate or ammonium alginate containing in suspension a finely - divided alkaline earth metal salt which is less soluble in water than the corresponding alkaline earth metal alginate.  The solution may be obtained by treating an alkaline earth metal alginate, e.g. calcium or barium alginate, with a solution of a salt of an alkali metal or of ammonium and of an acid of which the alkaline earth metal salt is less soluble than the corresponding alkaline earth metal alginate. The salt used may be an oxalate, phosphate, or carbonate.  The solution of alkali metal alginate containing the suspended alkaline earth metal salt may be extruded into a solution of hydrochloric, acetic, or other acid, the alkaline earth metal salts of which are soluble in water.  The alginic compound is coagulated in the form of filaments or films consisting of a mixture of the alkaline earth metal alginate and alginic acid. The coagulating liquid may contain a soluble alkaline earth salt, e.g. calcium chloride as well as the acid.  To complete the conversion of the filaments to alkaline earth metal alginate, they may be treated with a solution of calcium chloride containing calcium hydroxide or finely-divided calcium carbonate.  When ammonium carbonate is used to bring the alginic acid radical into solution, the solution may be extruded into air, and as the filaments begin to dry, the ammonia tends to evaporate, leaving the free alginic acid to react with the suspended alkaline earth metal carbonate.  The filaments are thus converted to the insoluble alkaline earth metal alginate.  Conversion may be assisted by treatment with a dilute solution of an alkaline earth metal salt or by treatment with steam. In an example, calcium alginate is dissolved in a dilute solution of sodium carbonate containing a little formaldehyde as preservative. The solution containing suspended calcium carbonate is extruded into a solution of calcium chloride and hydrochloric acid.  The filaments so produced are treated with very dilute hydrochloric acid and then with dilute calcium chloride saturated with calcium hydroxide.  In another example, a solution obtained by mixing calcium alginate, ammonium carbonate, ammonia, and water is extruded into calcium chloride solution, and the filaments so formed are treated with a saturated solution of calcium hydroxide. A similar alginate solution is extruded in the form of a thin film on to a glass plate and dried in the air.  The film is removed from the plate and either heated until free from ammonia or washed with calcium acetate and then with water, and then dried.
