Abstract: 1,084,882. Steam turbines. LICENTIA PATENT-VERWALTUNGS - G. m. b. H. Feb.17, 1965 [Feb. 17, 1964], No. 6852/65. Heading F1T. A split stuffing box 8 mounted within the unsplit inner casing 4 of a double casing steam turbine has an internal annular channel 9 receiving live steam from inlet pipes 4a through passages 9a and delivering through a split nozzle ring 11 mounted within the stuffing box 8 to the turbine live steam stages 14. The nozzle ring 11 is supported in a groove (23), Fig. 2 (not shown), in the stuffing box and is retained with freedom for expansion by a disc 12 and screws 13. The stuffing box is located intermediate the turbine live and reheated steam stages 14, 16, respectively, by bolts 6 passing through inner casing 4 and engaging a groove 27. In a modification, Fig. 3 (not shown), a portion (8a) of the stuffing box is separate from the remainder of the box and is retained by bolts (21). Bores (22), Fig. 4 (not shown), may be provided to tap off a small quantity of steam from the channel 9 to an annular groove (28) in the outer surface of the stuffing box 8 and thus reduce thermal stresses. In a further modification, Fig. 5 (not shown), for partial admission operation, radial partitions divide the channel 9 into a series of part-annular sections and an annular slot (26) is cut in the box 8 to reduce distortion.

Title: Improvements in or relating to gunn effect oscillators
IPC: H03B9/12
Filed: 1968-02-13
Abstract: 1,210,427. Gunn effect oscillators. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 13 Feb., 1968 [28 Feb., 1967], No. 6912/68. Heading H3T. In an oscillator having a Gun effect device biased below the oscillation level a resonator is coupled to the device so that when a pulse is applied to the device to cause oscillations to be produced the magnitude of the positive halfwave or waves of the oscillation produced in the resonator are of sufficient level to increase the effective level of the bias voltage applied to the device. This maintains the oscillations once the device has been triggered by an external signal such as a radio signal. The Gunn effect device may be connected to the inner conductor of a coaxial resonator and may be stopped from oscillating after some time by a control signal. The output oscillation may be rectified to provide a D.C. either applied in opposition to the D.C. bias voltage on the device so as to interrupt the oscillation or may be used to actuate an electrical or electronic relay to lower the D.C. bias voltage or switch it off. The oscillator may be used as a radio beacon controlled externally to emit a predetermined combination of frequencies for ship or aircraft navigation. The Gunn effect device may be a Group III-V semi-conductor.

Abstract: A process for concentrating aqueous acrylic acid comprises dissolving aqueous acrylic acid in a ketone which is at least partially miscible with water but immiscible with a concentrated aqueous solution of nickel, copper or cobalt salts and capable of forming together with water an azeotropic mixture boiling below 140 DEG  C. at atmospheric pressure, shaking the solution with a pulverulent anhydrous nickel, cobalt or copper salt, the relative quantities of aqueous acrylic acid, ketone and metal salt used being such as to form a concentrated aqueous solution of the metal salt and disposed as a layer on the metal salt solution-a solution of acrylic acid in water and ketone, the relative quantities of water and ketone being such that the water content of the azeotropic mixture of water and ketone at atmospheric pressure is not exceeded, and then, after separation of the upper layer from the lower layer, distilling off the azeotrope of ketone and water and finally anhydrous acrylic acid from the upper layer. The aqueous acrylic acid is suitably one having a concentration of 35 to 40% and specified ketones are methyl ethyl (propyl or isopropyl) ketone, diethyl ketone, ethylisopropyl ketone and di-isopropyl ketone.  Suitable salts are copper sulphate, cobalt chloride and preferably nickel chloride and/or nickel bromide and one or more of the metal salts may be used.  The shaking of the solution with the metal salt or salts should preferably be effected at about 40 DEG  C. and the subsequent azeotropic distillation and the acrylic acid distillation is preferably carried out in the presence of a polymerization inhibitor, e.g. hydroquinone.

[Classes 7 (ii) and 7 (v).] In a direct-acting motor compressor with oppositely moving pistons 23, 24, a vacuum is produced at the end of the working stroke by the pistons overrunning the exhaust and inlet ports 29, 30, which are on opposite sides of the central plane through the motor compresser. As shown, there are two sets of air inlets, which also serve as the suction inlets for the compresser sides of the machine. The two sets of air ports are connected to a common pipe 34 with two valved inlets 32, 33. The exhaust pipe has a bye pass 37 around the outlet valve 36 to allow some products to be drawn back into the cylinder and form part of the charge. Fuel is ignited by the heat of the compressed charge. Starting.-To drive the pistons outwardly at starting compressed air from a reservoir 47, Fig. 3, is admitted through the starter 38 ; this comprises a valve 39 held on its seat by a spring 41 and balance piston 40. To open the valve 39 a piston 45 is depressed by hand and compressed air flows to the underside of the piston 40 thereby allowing the air to lift the valve 39.
