Abstract: 474,033. Flame-machining. LINDE AIR PRODUCTS CO. April 21, 1936, No. 11344. Convention date, May 7, 1935. [Class 83 (iv)] [Also in Group XI] The surface of a metal member is shaped by the use of a number of oxidizing gas streams progressively and concurrently applied obliquely against and along such surface, one of the streams acting both on adjacent original surface metal and on newly exposed surface metal produced by a preceding gas stream. Two oxidizing gas streams may be applied by a single nozzle 16, Figs. 1 and 2, for shaping the edge of a metal plate 10, the lower stream b is supplied from a circular orifice 40, Figs. 6 and 7, which is directed downwardly relative to the nozzle axis and the upper stream a, which strikes the work nearer to the nozzle than the other stream, is supplied from a rectangular opening 39, the axis of which is laterally inclined to the nozzle axis. A group of passages 34 extend from the inlet end 35 of the nozzle 17 to the discharge end 36, being reduced in cross-section at their outer ends and adapted to supply combustible gas such as a mixture of oxygen and acetylene to heat the work. The two orifices for the supply of oxidizing gas open into a single passage 37 within the nozzle. The gas stream a shapes the radius 11, Fig. 2, and passes across the area previously operated upon by the stream b to produce a smooth surface. Other shaped edges may be formed by varying the shape and inclination of the orifices supplying the oxidizing gas. Apparatus for guiding the nozzle comprises a holder 54, Figs. 9 and 10, which is mounted on a carriage (not shown), rotatably adjustable according to graduated scales 55, 56 in two planes at right-angles. A plate 59 carried by the holder supports a linkage connected to another plate 60 which is constrained thereby to have parallel movement relative to the first plate. The plate 60 carries the nozzle N and this is held in constant spaced relation to the edge of the work 10 by a roller 65 which runs along the edge of the work and is mounted in a pillow 69 adjustable on an arm 71. this arm is adjustable in a block 73, to vary the inclination of the nozzle with respect to the work; and the block is rotatable about a rod 76 but is connected thereto by a torsion spring 77, an adjusting screw (7 enabling the elevation of the nozzle N to be changed, and the spring permitting the nozzle to be thrust downwards until the tip is.opposite the bottom surface of the work to effect the preliminary heating operation, the nozzle being subsequently released and oxidizing gas being then directed upon the work with the nozzle in its properly adjusted position at which it is fed along relative to the work.

Abstract: 475,734. Lathes. GOYOT, F. A. April 21, 1936, No. 11430. Convention date, April 23, 1935. [Class 83 (iii)] [Also in Group XXIII] A machine for turning and polishing copper printing-cylinders comprises a bed, a carriage f, Fig. 1, movable along the bed adapted to carry diamond or hard metal turning tools, and polishing stones or blocks u, Fig. 2, fixed to swing- able arms s with means for imparting a translatory motion to the polishing stones and means for moving these along the bed j. The tool carriage f, Fig. 1, is moved by means of a driving slide m on a guideway e at the front of the machine, a ball n transmitting the drive and thus preventing vertical movements of the driving slide being transmitted to the tool. A carriage i, Fig. 1, supported on a guideway h at the rear of the machine is adapted to be reciprocated and carries pillars q provided with vertical driving shafts which rotate crank discs p and impart a circular movement to a connecting rod o. Arms s adjustably connected to the rod o carry at their ends charcoal blocks u which are thus given a translatory motion along the surface of the cylinder o. The pillars q have apertures w which may support adjustable brackets and units along which the cylinder may be run to load or unload the machine. The tailstock b, Fig. 1, may be given a power traverse by connecting it, through the latch 4, with the driving slide m. Sag in the bed of the machine may be compensated by a screw-jack 5 which bears on a plate embedded in the floor.

Title: Improvements in engine starter drives
IPC: F02N15/06
Filed: 1933-04-20
Abstract: 420,363. Turning gear. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. April 20, 1933, No. 11640. Convention date, April 21, 1932. [Class 7 (v)] In an engine starter in which a pinion 2 is slidably journalled on a power shaft 1 and is automatically traversed into and out of engagement with an engine member 3, the pinion is connected to the shaft through two helical connections arranged in series, one of the connections being automatically disconnected when the pinion is thrown out of engagement with the member 3. As shown, a threaded sleeve 4, secured to the shaft 1 by a key 6 and a stud 7 threaded into a collar 8, is engaged by a nut 9 movable axially on the sleeve between the collar 8 and shoulders 12 on the sleeve. The nut 9 is normally retained on a smooth portion of the sleeve 4 by a light spring 13 bearing against an abutment ring 14 sealed against a collar at the end of the sleeve. A steep-pitched external thread on the nut 9 is engaged by a second nut 16 having lugs 21 slidable in slots 22 in a shell 19 engaging the teeth of the pinion 2 by means of lugs 23. A spring 27 is interposed between the nut 16 and the front end of the shell 19, which is closed at the rear end by a screw cap 25 forming an abutment for the nuts 9 and 16. In the position shown in Fig. 1, the nut 9 is urged against the threads of the sleeve 4 by means of a loosely mounted elastic spider 31, Figs. 1 and 9, having resilient arms 32 bearing against the end of the shell 19. On rotation of the shaft 1, the pinion 2 is moved into mesh with the gear 3 by the travel of the nut 9 into engagement with the shoulders 12 on the sleeve 4. Rotation is then transmitted to the shell 19 and pinion 2 through the nuts 9, 16, which form in co-operation with the spring 27 a yielding driving connection. If the teeth of the pinion clash with the gear 3, the pinion is turned into meshing position by the threaded connection between the nuts 9, 16. When the engine starts and the nut 9, carrying the pinion assembly, returns along the threaded sleeve 4 to the smooth portion, it rotates freely thereon and does not tend to rebound, and the inclined faces on the sleeve and the collar 8 dissipate by friction the momentum of the pinion assembly.

Abstract: 540,989. Thermionic valves and circuits therefor. STANDARD TELEPHONES & CABLES, Ltd. July 12, 1940, No. 11629. Convention date, Sept. 27, 1939. [Classes 39 (i) and 40 (v)] In an amplifier or oscillation generator the anode 15 is surrounded by the equipotential cathode 20 heated by the coil 21 ; the anode is supported in the metal envelope 10 directly at one end and by insulation 16 in the base. As an oscillation generator there is integral with the anode a loop 17 which ends in a plate 18, which with dielectric 19 and the wall base form a condenser; a coil 36 is placed within the loop and is connected by the lead 28 and a metal cylinder 26 to the cathode. Leads 30, 31 are provided to allow a D.C. to flow along the anode and generate a co- ,axial magnetic field. The feed back through coils 17, 36 varies the effect of this field which at times inhibits flow of electrons to the anode and thereby produces oscillation. The condenser 33, Fig. 3, formed by the plate 18 &c. is placed across the D.C. source 32 producing the magnetic field. As an amplifier the coil 36, Fig. 4, acts as output winding the anode circuit including the battery 32 and the inner conductor 39 of a coaxial cable which is connected to the input 40.

Title: Improvements in textile printing
IPC: D06P5/12
Filed: 1944-06-23
Abstract: Printing; regenerated celluloses, dyeing.-In the resist printing of fabrics of cellulosic fibre, e.g. cotton, or viscose or other regenerated cellulose artificial silk, by printing on the fabric a resist paste containing chemicals (reducing agents and/or acid-binding agents) which inhibit the oxidation of oxidation dyestuffs, and then applying (e.g. by padding or over-printing) an oxidation dyestuff in conjunction with an oxidizing agent, the purity of the white pattern is enhanced by the treating the fabric, or at least that portion of it which is to receive the resist paste, with a small proportion (e.g. 0.05 to 0.2 per cent calculated on the weight of the treated portions of the fabric) of the free acid or a water-soluble salt of 4 : 41-di-(benzoylamino)-stilbene-2 : 21-disulphonic acid of a substitution product thereof substituted in the benzoyl nuclei.  The stilbene derivative may be applied at any stage in the process, but is conveniently incorporated in the resist paste, which may be applied by machine printing, screen printing, block printing or spray printing.  In examples: (1) cotton fabric is printed with a resist paste containing zinc oxide, sodium acetate, gum tragacanth thickening, potassium sulphite and the sodium salt of 4 : 41-bis-(p-aminobenzoylamino) - 2 : 21 - disulphostilbene, dried, padded with an aniline black paste containing aniline hydrochloride, sodium chlorate and potassium ferrocyanide, dried, steamed, immersed in an aqueous bath containing potassium dichromate and acetic acid, rinsed, soaped and dried; (2) cotton fabric is printed with a resist paste containing zinc oxide, British gum thickening, soda ash, potassium sulphite, sodium formaldehyde sulphoxylate dihydrate and the same stilbene derivative as in (1), dried, padded in a solution containing p-aminodiphenylamine sulphate, lactic and acetic acids, gum tragacanth thickening, sodium chlorate, monoacetin, ammonium sulphocyanide and ammonium vanadate, dried, steamed, rinsed and soaped; (3) cotton fabric is printed with a resist paste containing British gum thickening, sodium formaldehyde sulphoxylate dihydrate, sodium acetate, potassium sulphite and the same stilbene derivative as in (1), dried, padded with a solution containing chloro-p - phenylenediamine sulphate, monoacetin, ammonia, gum tragacanth thickening, sodium chlorate and vanadium chloride, dried, steamed, rinsed and soaped.  p-Phenylenediamine is also specified as an oxidation dyestuff, and other suitable stilbene derivatives are 4 : 41-bis-(p-acetylaminobenzoylamino)-stilbene-2 : 21-disulphonic acid and 4 : 41 - bis - (p - ureidobenzoylamino)-stilbene-2 : 21-disulphonic acid (obtainable by condensing 4 : 41-bis-(p-aminobenzoylamino) - stilbene - 2 : 21 - disulphonic acid and sodium cyanate in aqueous medium in the presence of a small quantity of acetic acid).

Title: Improvements in or relating to pressure limiting devices for automatic compressed air brake systems
IPC: B60T15/50
Filed: 1945-05-14
Abstract: 581,437. Brakes. GALLUSSER, H. May 14, 1945, No. 12062. Convention date, March 15. [Class 103 (i)] In a compressed-air automatic braking-system having distributor valves SV each with a constant pressure control chamber, overcharging of the control reservoir S during the filling of the trainpipe H is prevented by a valve DB between the main reservoir L and the driver's valve BV, the valve DB having a chamber 33 subject to constant pressure from an auxiliary control reservoir HS, a chamber 32 subject to auxiliary reservoir pressure and a chamber 31 subject, in @turning and release positions of the valve BV, to train-pipe pressure. In charging the system initially, a hand-valve U<2> connects the reservoirs HS and L until a pressure of, say, 5 atmospheres in HS against 7 atmospheres in L is established, when the valve U<2> is closed. This pressure raises the rod 34 and opens the valve 36 against the action of a spring 35, thereby connecting the train-pipe H through the valve BV and pipe 41 to the main reservoir L. The valve 36 remains open although the pressure in the chamber 31 rises to 7 atmospheres, but as the auxiliary reservoir pressure in the chamber 32 rises, the pressure in the chamber 31 must fall if the valve 36 is to remain open. Equilibrium is reached, and the valve 36 remains closed, when each chamber 31, 32, 33 contains 5 atmospheres. On a brakerelease, therefore, the auxiliary reservoir HL may be re-charged quickly by admitting 7 atmospheres to the train-pipe, but as the auxiliary reservoir pressure approaches 5 atmospheres, the train pipe pressure falls towards the same level. As the control reservoir S is connected to the train pipe only when the auxiliary-reservoir has been charged to about 4.9 atmospheres, it is not possible to overcharge it: By varying the pressure in the reservoir HS, the pressures in the train pipe, and reservoirs S, HL are varied identically.
