Title: Improvements in or relating to taps for the control of fluids
IPC: F16K31/44
Filed: 1938-01-17
Abstract: 492,033. Valves combined with electric switches. HERSEY, J. C. Jan. 17, 1938, No. 5052. [Class 135] In a tap of the screw down type, the operating member 6 is provided with one or more pawl devices 8 which co-operate with the actuating elements 9 of one or more switches of the type which must be moved positively in each direction, the element or elements being fixed as regards the axial travel of the member 6 the turning movement of which causes the pawl device or devices to operate them in a tangential direction. The switch 2 and the tap body 1 are maintained in fixed relation by a bracket 3 or otherwise. The screwed valve spindle 6 carries a hand wheel 7 and a pawl device 8 comprising a collar 10 with side flanges 11, 12 embracing pivoted pawls 13, 14 pressed outwardly by springs 17, 18. When the spindle 6 has been moved into a position in which the pawls 13, 14 are opposite the switch actuating element 9, further rotation of the spindle in the same direction causes one of the pawls, say 13, to bear with its working face 19 against the element 9 and move the switch to its alternate position. Continued rotation of the spindle in the same direction has no effect on the switch, but on reversing the rotation the working face 20 of the pawl 14 is operative to return the switch to its initial position when the pawl device is again aligned with the element 9. The end of the element 9 is of less width than the distance between the flanges 11, 12, these being cut away at 30 to prevent jamming with the switch element 9. The tap may be used to control the electric water heater described in Specification 474,826, [Group XI].

Title: Method of deflecting a hot gas jet passing through a nozzle for carrying out the method
Inventor: BERTIN JEAN HENRL
IPC: F02K9/82
Filed: 1963-02-08
Abstract: 1,028,465. Deflecting aircraft propulsion jets. BERTIN & CIE. Feb. 8, 1963 [Feb. 8, 1962; Jan. 15, 1963], No. 5191/63. Heading B7G. [Also in Division F1] A hot gas jet flowing in a nozzle, e.g. of a rocket engine, is deflected by injection of a liquid into the flow from the nozzle wall, the expansion of the liquid along the nozzle wall deflecting the jet. Fig. 1 is a half section through a nozzle in which liquid is injected into the boundary layer on the nozzle wall through nozzles 7 formed between two parts 4, 6 of the graphite nozzle lining. Injection may alternatively take place at or upstream of the throat 5. The fluid may be injected with an upstream component of velocity. The liquid, in the slow-moving boundary layer, has time to vaporize, decompose and/or to react with the gases of the jet, the resulting rapid expansion causing a shock wave and detachment of the flow from the nozzle wall at 12. A slow-moving wake 13 is formed. In case the liquid in the feed pipe 8 becomes heated and decomposes (in the case of a monopropellant) while liquid is not being injected, the pipe 8 may feed several smaller conduits each discharging into a nozzle 7, these smaller conduits withstanding high pressures better. The injected liquid may have been used for cooling the nozzle. A second set of injection nozzles spaced axially of the nozzle from the first set may be provided, the same or a different liquid, or a gas, being injected therethrough. The injection slots or apertures may be formed in inserts cemented into the nozzle lining, the exposed face of each insert being coated with tungsten. Such an insert may have a plurality of injection bores 39 communicating with a common plenum chamber in the insert, Fig. 11, and a second liquid may be injected through a pipe system 42. Alternatively, the insert may define a plenum chamber with the nozzle wall, and be of a porous material, e.g. sintered metal.

Abstract: 961,554. Screening apparatus. F. F. DAUENHAUER. Feb. 13, 1961, No. 5328/61. Heading B2H. A machine for separating hops from extraneous matter includes an inclined endless screen 21 with its upper run moving upwardly and fed with a mixture of hops and foreign matter from a shaker conveyer 13 and under the control of pivoted baffles 16, 18. The conveyer is supplied from a preliminary separator 11 fed from a conveyer 12. Some small stems and leaves pass through the screen 21 and fall to a trash conveyer 45, and other foreign material is carried over the top pulley 41 of the screen and falls to the trash conveyer. Hops and larger leaves, stems &c. move downwardly on to a stationary imperforate plate 22 which retards the movement of the leaves, and the material falls on to a more steeply inclined endless screen 23 with its upper run moving upwardly. As shown in Fig. 2 the plate 22 is parallel to the upper run of the screen 21 and is attached to a lower pulley bracket 44. A deflector 46 controls the fall of hops which separate from the mixture as it leaves the screen 21 and plate 22 so that the hops fall on to the screen at the desired point. The leaves which fall from the plate 22 are blown on to the screen 23 by a blower 61 and are carried over the pulley 58 of the lower screen and fall on to the trash conveyer. Hops pass downwardly over the screen 23 and are received on a multi-slotted surface 70 through which small leaves and stems fall to the trash conveyer ; the hops then pass to a take-off conveyer 68. The lower pulleys of the inclined screens are self-cleaning and are in the form of drums comprising perforated ends 71, 72, Fig. 3, and a central imperforate disc 74 interconnected by spaced rods 78, thereby providing compartments 76, 77. A helix 79 ensures that foreign material which may collect within the drums is conveyed through the ends 71, 72 and falls to the trash conveyer.
