Title: Improvements in axial flow turbines having a tip turbine fan
Inventor: SIMONSON MARVIN RAY
IPC: B64C29/00
Filed: 1963-09-02
Abstract: 997,465. Turbines; jet propulsion plant. GENERAL ELECTRIC CO. Sept. 2, 1963, No. 34537/63. Headings F1G, F1J and F1T. An axial flow tip turbine driving a fan comprises turbine nozzle and rotor blades having a constant cross-section and blade angle from root to tip and a turbine flow path having a portion curved to offset the centrifugal force due to the working fluid tangential velocity from the nozzle blades whereby in operation the static pressure gradient across the flow path is substantially zero. The casing 20, Fig. 3, of a tip turbine driven fan 9 comprises inner and outer walls 18, 19 surrounding the turbine rotor blades 10, upstream nozzle vanes 12 and guide vanes 21. The curvature of walls 18, 19 in an axial plane is such that the centrifugal force due to the working fluid tangential velocity from nozzles 12 is offset whereby the radial static pressure gradient across casing 20 is substantially zero. The mathematical calculation of the curvature of walls 18, 19 is described. The nozzles 12, blades 10 and vanes 21 are of constant aerofoil cross section and are untwisted from root to tip. A scroll 24, Fig. 4, may lead into casing 20 when the fan 9 is mounted in the wing of an aircraft to provide vertical lift.

Abstract: 651,862. Cheese. WOUD, H. Dec. 30, 1947, No. 34643. Convention date, June 8, 1945. [Class 84] In a process of manufacturing a dried cheese product the initial cheese material is converted into a molten mass by breaking up, rolling and incorporating during rolling an aqueous solution of citric acid and sodium carbonate, the amounts of which are controlled according to the acidity of the initial cheese material so as to yield in the resultant molten mass a pH between 6.5 and 7.0 and the molten mass is then heated with sufficient water and agitation to effect emulsification and thereafter dried in finely divided form. As shown, the raw cheese is fed into a screw mill 1 broken up and passed to a rolling unit 2 where during rolling the mixture of citric acid and sodium carbonate is fed from a mixer 3 by a sprayer 5. The rolled cheese mass is then mixed in the hopper 6, passed into a conveyer 9 having an internally-heated screw 11 from which it is discharged at 10 to internally steam heated drying rolls 12 and formed into a dried mm which is scraped from the last roll and reduced to powder by a rotating brush 14. The powder may be passed through a shaking sieve 15 and pressed into blocks by a press 16, wrapped and labelled by a machine 17 and removed by conveyers 18. In an example to each 100 Kg of fullcream cheese (fat content 45 per cent) is added a solution prepared from 6 litres of water, 3,000 grms. citric acid and 2,250 grms. sodium carbonate.

[Classes 83 (ii) and 83 (iv)] [Also in Group XI] In a machine for making supports for the filaments of tubular electric incandescent lamps vitreous pellets 32 are secured at intervals along a metal rod 10, and wires 170 are inserted into the beads and bent at their free lower ends to receive the filament, the wires being severed in succession from a length 115 which is unwound from a spool carried by a vertically reciprocating slide 113, Fig. 4. Shearing.-The metal rod 10 is advanced intermittently through the machine, above the bead-applying and wire-inserting devices. The upper part of the wire 115 is threaded through slots in a slide 116 and held beneath a leafspring 117, with the end of the wire projecting. The slide 116 is coupled to the slide 113 by a cam plate 120 which is mounted on a fixed pivot 123 and provided with two slots which engage pins 121, 124 respectively on the slides 113, 116. When the slides are moved downwardly a length of wire is severed by a horizontally sliding cutter 132 fastened to a plate 134 which is connected to a lever 135 pivoted on a pin 138 and provided at its lower end with a roller 139 engaging a cam slot 140 in the slide 113, whereby the cutter is moved inwardly over a block 133 to sever the wire. The block 133 is secured on a plate 136 which is moved inwardly towards the cutter under the action of a lever 143 pivoted on its underside. The plate 136 forms a support for the cutter 132 and is pressed against the underside of the cutter by a spring 148 on a bolt 149 which passes through a longitudinal slot in the plate 136 and is screwed into the plate 134. Angular bending.-As the wire is being severed, a cam 150 extending from the plate 134 engages the free end of a wire 151 which has one end secured to a plate 154 by a screw 155, and the free end 152 bent at a right-angle so that it can be pushed through an aperture in the plate and form a mandrel against which the end of the severed supporting-wire 170 is bent sidewardly and then into the form of a hook by pressure from a pin 156 carried by a lever 157. The lever 157 is actuated by a link 160 which is connected to one arm of a lever 163 adapted to be rocked by its other arm engaging a roller 164. Specification 461,590 is referred to.
