IPC: F22B1/16
Filed: 1923-05-04
Abstract: 212,778. Haag, J. May 4, 1923. Superheating by steam.-An evaporator, steam generator and steam superheater are arranged so that vapour flows directly from the evaporator in contact with the superheater and generator, the condensate returning to the evaporator and the vapour pressure being kept substantially constant. A liquid such as a hydrocarbon with a boiling point of about 400‹ C. is evaporated in a drum 6 from the bottom of which extend Fieldtubes 4. The vapour passes to a drum 10 and condenses on the water-tubes of a steam generator 11, any uncondensed vapour passing by a pipe 13 to a collector 14 open to the atmosphere at 15. The condensate passes back to the drum 6 through a pipe 12, and a valve 17 is opened at intervals to recover the condensate from the collector 14. Steam flows from the generator to a drum 18 in the collector 14 through a nozzle 19, the lower end of which determines the water level in the generator as described in Specification 159,498, [Class 123 (ii), Steam generators], and then from the dome 20 through a pipe 7 to the superheater 8 in the drum 6. The air in the apparatus may be replaced by nitrogen to prevent oxidation of the evaporating liquid. In a modification, the generator drum is open at the top and is placed within the evaporator drum, superheating coils surrounding the superheater drum. Additional steam may be supplied to the superheater from an independent source. The vapour collector may have vertical cooling tubes.

[Class 40 (iv)] [Also in Group XL] Variations in attenuation and impedance in a transmission system with temperature are compensated by means of one or more networks comprising thermistors and reactance elements. Numerous networks comprising one or two reactances in various positions in relation to the thermistor are described. A preferred arrangement is shown in Fig. 21 in which a network comprises a thermistor T, shunted by a resistance RS 1  and by a condenser C 1 , the whole being in series with a second thermistor T 2  shunted by a resistance RS 2 . Similar compensating networks are connected in both legs to avoid unbalance. In general the attenuation is compensated mainly by a unit at the middle of a section and the impedance by units at the ends. In the case of a loaded line the compensating networks are preferably separated by intervals equal to the distances between loading coils and their nature is determined by the position in the section at which they are placed. In a carrier system, the compensators are provided at the rate of # or more per wavelength. Specification 540,844, [Group XXXVI], is referred to. the cathodes of the tubes associated with such parties. Otherwise the cathodes of the other tubes remain connected. The connection of battery to the line causes ionization to take place in the tube of the calling line and discharges to occur via the appropriate register relays which lock up, control a printer or number indicator in known manner and jointly complete a circuit for a relay CK which extinguishes the tube. The register relays are unlocked by a relay 416 when the printer has completed its operation.

Abstract: 700,821. Engine valve-gear. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 21, 1952 [May 29, 1951], No. 12558/51. Class 122 (2) In a uniflow engine the working fluid is admitted through two valves arranged in series one of which is a piston type cut-off valve having a circumferentially extending cut-off edge cooperating with a port in its cylinder and arranged so that the point of cut-off can be varied by rotation of the valve relative to its cylinder whilst the other is an admission valve that opens when the piston valve is open. In a two cylinder uniflow steam engine with cranks at 180 degrees the point of cut-off in each cylinder is respectively controlled by the co-operation of two inclined cut-off edges H, H<SP>1</SP> of a single piston valve G<SP>3</SP> with ports G, G' in the valve cylinder G2 leading via chambers F, F<SP>1</SP> to the cylinder admission passages D, D' each respectively controlled by a cam actuated spring-loaded poppet admission valve E, E'. The piston valve G3 is reciprocated by an eccentric M<SP>5</SP> and its stem G4 is surrounded, where it extends through the valve casing B5, by a sleeve J<SP>1</SP> having tongues engaging grooves in the stem G4 and fixedly carrying an arm N connected by a rod N' to a lever N<SP>2</SP> controlled by a centrifugal governor N3 so that operation of the governor causes rotational movement of the sleeve J<SP>1</SP> and piston valve G<SP>3</SP> to vary the cut-off in each cylinder ; the cut-off being retarded when the engine speed falls and vice versa. The ends of the piston valve cylinder G<SP>2</SP> are in continuous communication due to longitudinal grooves H<SP>2</SP> extending from each cut-off edge H, H' to the piston end remote from that edge. During operation port G or G<SP>1</SP> is uncovered by the cut-off edge H or H' prior to the point of admission of the appropriate cylinder which is controlled by opening of the admission valve E or E' and steam is admitted from a supply passage L through the port G or G', chamber F or F', valve E or E' to the appropriate cylinder. During normal running conditions the cut-off in each cylinder is controlled by the closure of the appropriate port G or G<SP>1</SP> by the cut-off edge H or H<SP>1</SP> of the valve G<SP>3</SP>-the admission valve E or E' closing later-but at a predetermined overload condition the piston valve G<SP>3</SP> is rotated to the position in which the grooves H<SP>2</SP> register with the ports G, G<SP>1</SP> which then remain permanently open and both admission and cut-off are controlled by the admission valves E, E<SP>1</SP>.

Abstract: 514,113. Milling-cutters. MAMMANO GEAR CO., Ltd., and MAMMANO, B. April 27, 1938, No. 12561. [Class 83 (iii)] A face milling - cutter for the continuous generating of curved-tooth bevel gears has finishing blades spaced at an' angle and within which are located subsidiary finishing blades, 'while roughing blades are arranged in the remaining angle of the tool face. In Fig. 1 the finishing blades V and Ware arranged at 180 degrees on the tool disc, a point E in the pitch plane and lying in the external edge of the blade V which finishes the surface A, B being at the same distance from the centre P as the corresponding point I in the internal edge of the cutter W which finishes the surface C, D. According to the invention the finishing blades Fi, Fe, Fig. 2, separated preferably by an angle a of 160 degrees in the case of the tool for cutting the pinion of a pair are associated with a number of other blades, all of the same rack section. For cutting the gear member, the finishing blades are arranged at 200 degrees, Fig. 3, on the tool disc, the sum of the angles between Fe and Fi on the two cutters being 360 degrees. The two cutters rotate in opposite directions for cutting the pinion and gear respectively, and by spacing the finishing blades. As described the tooth space cut is less than half the pitch on the pinion and correspondingly greater than half the pitch on the gear. Between the blades Fi and Fe are arranged a number of subsidiary blades S1, S2 &c. which cut on the -external edge and relieve the work of the finishing blade Fe. The sum of the radial differences in the settings of the blades S1 ... Fi is equal to the pitch thickness MN of the blades and the differences are graded to distribute the cut between the blades. The roughing blades R1, R2 &c. cut mainly on the internal edge and are set progressively at different heights. Fig. 7 of the drawings in the Provisional Specification shows the manner in which the blades a are adjusted to the desired radial settings, the screwed bush d being rotated after releasing the stamping bolt b. Formulae are given in the Specification for determining the settings of the roughing and finishing blades. Specification 465,008 is referred to.
