IPC: A47J31/047
Filed: 1950-07-31
Abstract: 684,990. Thermal switches. SUNBEAM CORPORATION. July 31, 1950, No. 19125/50. Class 38 (v) A thermal control device for a coffee maker or other heating appliance, particularly one which requires a high temperature such as 240‹F. to be first attained and a subsequent lower temperature such as 180‹F. to be maintained, comprises a bimetal element 55 fixed at one end 52 to the appliance and at its other end to a bowed spring 59 fixed to a member 60 pivoted at 62 and carrying a handle 49 whereby the device may be moved over a dead centre position into the position shown in which the bimetal strip lies in close contact with the appliance. In this position contacts 65, 71 in the circuit of the heater 18 are closed. When the appliance reaches a temperature of 240‹F. the bimetal strip 55 moves down and the parts 55, 59, 60 snap past the dead centre position and operate a stud 79 to open contacts 65, 71. Adjustment for the above temperature is by a screw, not shown, which alters the position of the pivot 62 and thus the degree of stress in the bowed member 59, which is in the form of a flat loop, Fig. 2 (not shown). The appliance now cools down till at 180‹F, the slight consequent flexing of the bimetal strip (insufficient to reach the dead-centre position) causes contact to be remade. Adjustment for this temperature is by alterating the position of the stud 79 and if carried sufficiently far may be such that the parts begin to snap across the dead-centre position before the contacts close. With such an adjustment, the device will only provide one range of temperature instead of two.

Abstract: 1,166,971. Automatic exchange systems. SIEMENS A.G. 24 April, 1968 [25 April, 1967], No. 19312/68. Heading H4K. In a multistage switching network comprising matrices of remanent relays, each interstage link has associated therewith a non-remanent relay the operation of which at the end of a call causes the release of the crosspoint at which the link terminates. In the three stage network shown, only the release windings KAII, KBII, KCII of the relevant crosspoint relays between a connected inlet and outlet VS1 are depicted. Each link includes a control wire h, zlab, zlbc which is switched through at crosspoints ka, kb, kc when the crosspoint relays are energized. At the end of a call contacts d1, d2 close and c recloses whereby non-remanent relays HA, HB, HC which are associated with the relevant links come up. In so doing their contacts 2ha, 2hb, 2hc complete a path through the release windings of the relevant crosspoint relays and those of the link busy relays ZAB, ZBC which thereby fall back. The release of the link busy relays is noted in an associated path-seeking network. Contacts d1 are opened later in order to release the link relays HA, HB, HC.

Title: Improvements in or relating to weighing balances
IPC: G01G21/23
Filed: 1943-11-23
Abstract: 581,929. Weighing-apparatus. HONEGGER. W. Nov. 23, 1943, Nos. 19572 and 19573. Convention dates, Oct. 24, 1942, and Sept. 14, 1943. [Class 143] In a weighing balance, the load carrier is supported by balls or rollers on inclined bearer surfaces, the load being counterbalanced by a roller device which is caused to roll up inclined guide surfaces, parallel to the bearer surfaces, by the movement of the load carrier, springy metal tapes being wound on the roller device as it moves up the guides. As shown in Fig. 1, the pan support 1<1> rests upon balls 5 situated between inclined surfaces 3 and rails 4. A load on the pan causes the balls to roll down the inclines, and an arm 8 rigid with the pan support pulls upon a steel band thereby causing a roller 13 to travel up a pair of inclines 14 and winding upon itself steel tapes 17. A rack 19 connected to the roller by a steel band actuates the indicating pointers 23, 27. Stops 7 limit the movements of the pan support. In a modification, the movements of the pan support are transmitted by means of segments, roller, and rack connected by steel bands. This arrangement avoids out-of-level error. In an embodiment shown in Fig. 5, the depression of the load carrier 1<1> causes a roller 83 to move up an incline 82, the movement being transmitted to an indicator 88 by mechanism 87. The indicator may carry a magnifying glass 89. The Specification as open to inspection under Sect. 91 comprises also a modification shown in Fig. 4 (Cancelled) in which the pan support rests on transverse spindles 36, 37, undesirable movement being prevented by steel bands 39. The load is counter-balanced by a weight 46 or by a poise weight on an arm carried by the spindle 36. The load may be counter-balanced by a weight suspended from a disc carried by the spindle 36. This subject-matter does not appear in the Specification as accepted.

Abstract: 733,927. Heat-treating metal wire &c. REINECKEN, W. Aug. 1, 1952, No. 19586/52. Class 72. [Also in Groups XI and XXV] Metal wires, strips, or tubes are continuously heat-treated by subjecting the material to a single electric current, the tempering temperature being controlled by suitable displacement of a quenching nozzle to define a heating path and a tempering path. The process may be carried out in a protective atmosphere and the speed of movement of the material controlled by a relay and temperature sensitive instrument. As shown, a wire may pass through straighteners 2, conductor rolls 3, a quenching nozzle 4 having one adjustable fluid outlet and being adjustable longitudinally of the wire, conductor rolls 5, straighteners 6 and a final cooling device 7. The wire may be given a coating of phosphate or another metal or may be subjected to ultrasonic vibrations while passing through the tempering path. Short lengths of wire may be joined by a double conical clamp, Fig. 2 (not shown). The conductor rolls may be immersed in a conducting liquid, and the wire in the tempering path may be subjected to plastic deformation.

Title: Manufacture of azo-dyestuffs on the fibre
IPC: D06P5/12
Filed: 1932-07-11
Abstract: Azo dyes, forming on the material; printing.--In the production of azo dyestuffs on the fibre by impregnation with a solution of a substantive coupling component and subsequent development with a solution of a diazo compound, the material is passed, immediately after the treatment with the diazo solution, through a space heated substantially above the atmospheric temperature in order to accelerate and complete the coupling operation.  Processes in which the material is impregnated with an o -methylsulphonic acid of an aromatic amine in addition to a substantive coupling component are excluded.  The method is of particular advantage in using diazo compounds which couple slowly and in the production of resist effects.  Specified slowly coupling diazo compounds are those of aminodiarylamines and related compounds such as the diazo components of Specifications 286,274, 313,865, and 329,960, [all in Class 15 (ii), Dyeing, Processes &c. for].  The following examples are specified.  (1) Material, grounded with a liquor containing the anilide of 2 : 3-oxynaphthoic acid, turkey red oil and caustic soda, is dried and passed through a cold bath containing the diazonium chloride of 4 - amino - 4<1> - methoxydiphenylamine and is immediately, without exposure to air, passed through a steamer wherein it is treated at 110--115 DEG  C. for about 30 seconds, passed through a bath at 40 DEG  C. containing dilute hydrochloric acid, rinsed and soaped.  (2) Material, grounded and dried as in (1), is printed with an aqueous white resist paste containing aluminium sulphate, starch tragacanth thickening and kaolin, dried, passed through a cold diazo bath as in (1), immediately passed through a steamer as in (1) or between pairs of flat hollow steam-heated iron plates, passed through a bath at 80 DEG  C. containing dilute hydrochloric acid, rinsed, passed through a bath at 80 DEG  C. containing sodium bisulphite, rinsed and soaped to obtain a white resist on a blue ground.  (3) The white resist paste of (2) is replaced by an aqueous yellow resist paste containing the sulphuric acid ester salt of leuco-3 : 4 : 8 : 9-dibenzopyrene-5 : 10-quinone, ethylene glycol, diethylene glycol, the monoethyl ether of diethylene glycol, starch tragacanth thickening, sodium bisulphite, ammonium thiocyanate, chrome yellow and kaolin, and the development and further treatment are as in (2).  (4) The yellow resist paste of (3) is replaced by a similar aqueous green resist paste containing, as the sulphuric acid ester salt, that of leucodimethoxydibenzanthrone, and the development and further treatment are as in (2).

Title: Double-flow gas turbine
IPC: F01D25/16
Filed: 1947-07-25
Abstract: 625,377. Bearings. TRIGGS, W. W. (Akt.- Ges. Brown, Boveri, & Cie). July 25, 1947, No. 20025. [Class 12 (i)] [Also in Group XXVI] The rotor a of a divided flow low-pressure gas turbine is held in the casing b by means of two thrust bearings c, d, which are displaceable axially so that the planes of symmetry of both halves of the rotor and stator approximately co-incide under all conditions of operation. The bearings c, d, Fig. 7,. which may be mounted on the casing b, are loaded by springs g which press towards the centre 1-2 of the machine so that as the rotor expands the stress in the springs is increased. The supporting element of the thrust bearing is formed as a piston so that when the spring casing is filled with oil it provides means for damping out any axial oscillations of the rotor. Oil pressure may be used instead of the springs g. In this case, the supply of oil to the casing must be controlled by the edges of the damping piston so that the oil pressure increases as the rotor moves away from the symmetrical position. In the arrangement shown in Fig. 9, the thrust bearings are connected by means of rodding i, k, l, m and n which allows extensions of the rotor but prevents its displacement. By means of unsymmetrical rodding, it is possible to distribute the expansion of the rotor in any desired ratio over the two bearings. If desired, the levers i, n may be pivoted -on the casing b.
