Title: Improvements in and relating to jet propulsion apparatus for the driving of vehicles, ships, boats, flying machines and the like
IPC: F02K5/00
Filed: 1924-03-18
Abstract: 235,630. ValdÚs, S. March 18, 1924. Jet propulsion apparatus.-The nozzle of a jet propulsion apparatus is formed with a central hub portion merging into an aft portion, forming a pair of broad shallow lips from between which pressure fluid is directed and the external surfaces of the body are curved with convergent surfaces so as to direct the outer medium over the lips. The central hub a, Figs. 1 and 2 extends into flat lips h, c forming a shallow fluid outlet d. The outer surface e of the lips is stream lined. The nozzle is fitted near the keel. The lips may be provided with guide vanes g. Instead of a fixed nozzle it may be pivotally mounted for steering and reversing, and for submarines may be universally mounted for manoeuvring. The lips may each be in two parts pivotally connected for varying the shallowness and broadness of the jet. For propelling a life-line rocket, a body u, Fig. 9, carrying a gas-generator w is fitted with a reaction apparatus v with shallow lipped discharge x. As applie dto aeroplanes, Fig. 10, a turbine 16 discharges air between lips b, c. The device is adaptable also for propelling overhead cable or telfer suspension vehicles, airships, torpedoes, seaplanes, and motor cars. More than one nozzle may be fitted as desired.

Abstract: 144,810. Andrew, H. F. March 20, 1919. Stropping-apparatus.-A safety razor, shown in Fig. 2 as disposed for sharpening by a to-andfro movement on a strop &c. 24, comprises a blade 1, Figs. 2 and 4, mounted in a carrier 2 of sheet metal, which is doubled round a spindle 7 and made to engage frictionally therewith. The spindle 7 is pivotally supported in a handled U- frame 5. The carrier 2 is indented at 14, 15 to engage notches in the blade sides. A thin reversing-plate 3 with doubled-over parts 10, 11 has recesses 12, 13 engaged by mutilated toothed wheels 8 on the spindle 7. The plate 3 has a plain-edged or serrated cross-bar 4 acting as a guard during shaving, when hooks 22, 23 receive the blade-edge; the plate 3 may be roughened or may carry a metal or other dressing in order to grip the strop during sharpening. In the sharpening position, if the frame 5 is kept depressed it is free, between the strokes, to ride on the frame 3 within the limits of the slots formed by the doubled-over parts 10, 11, the frame 3 being retained frictionally on the strop, so that the blade is reversed by the wheels 8 engaging t'he recesses 12, 13, and the parts being such as to give the correct stropping-angle, The blade may be stropped on one side only by restraining its rotation by finger pressure. In the position shown in Fig. 2, the frame 5 may be raised so that projections 18 on it engage slots 20 in the plate 3, the blade being thus raised by the pinions etc.; the blade may then be depressed and guided and forced into engagement with the guard hooks 22, 23. The blade-edge may similarly be adjusted in relation to the guard, or adjusted by moving the guard by the thumb; the full lines in Fig. 4 show the normal position for shaving, and the dotted lines positions with fine and coarse adjustments. The guard and blade may fold flat on the frame 5, and means for holding the parts in the various positions may be provided. A device for stropping only is shown in Fig. 6, the reversing-plate 3 being of arcuate form with a rack part 25, and the lower part having a cross-bar 26 connecting the sides 27, formed as shown on the lower face; the plate may sometimes be linked to the frame 5. In another form, the frame 5 is slotted and toothed, the plate 3 being triangular and carrying the blade-spindle and toothed wheels. Other modifications of this stropping-device may be made; also modifications of the means for adjusting the blade-edge with respect to the guard, in the razor construction.

Rolling-machines.-A machine for rolling explosives or similar gelatinous substances is furnished with two rollers of different diameters, one in fixed and the other in sliding bearings, both being driven by different-sized worm wheels, from an inclined or vertical worm shaft. Fig. 1 shows a larger upper roller 19 and lower roller 21 mounted in bearings in end frames 1. One end frame carries bearings for an inclined shaft 9 gearing with the two rollers. The bearings for the upper roller are fixed in position by the bolts 11, while those for the lower roller slide parallel to the worm shaft in the inclined slots 5 in the end frames and are adjusted by the wedge 28 which is operated as described in Specification 250,334. The rollers are preferably hollow and heated. In a modified construction the worm shaft is vertical and the smaller roller above the larger one. The driving-gear is selected so that the peripheral speed of both rollers is equal; the driving worms being of equal and opposite pitch. The rollers may be provided with registering projections and recesses to stamp numbers on the rolled product. In this case hand-operated worm gear is provided to adjust the lower roll after it has been moved in its bearings, so that the projections and recesses will register accurately in the new position. Specification 252,048 also is referred to.

Abstract: 1283513 Welding by pressure UNITED AIRCRAFT CORP 13 Feb 1970 [2 April 1969] 7135/70 Heading B3R A process for concurrently bonding and coating metallic components formed of nickel base or cobalt base alloys comprises positioning the components with the surfaces to be joined in intimate contact and coating and diffusionbonding the components by heating in a reducing atmosphere of coating vapour to a temperature in excess of 982 C., preferably 1093 C. The coating vapour may be metallic chromium and the process may be carried out by embedding the components in a dry impregnation pack comprising a source of chrom-   ium (e.g. chromium or chromium alloy powders) a source of halogen vapour (e.g. ammonium chloride) and an inert mineral filler (e.g. activated alumina). The pack is preferably heated to within the range 1093-1399 C. and heating continued to coat the components to a thickness of at least 25À4 microns, preferably, 50À8-127 microns. The reducing atmosphere serves to remove oxides at the interface to be bonded and slight irregularities therein can be accommodated since the coating material tends to build up on parts not in contact. Coating may be carried out alternatively by vacuum vapour deposition. Specific, compositions of nickel base and cobalt base alloys are given.

Title: Improvements in electric remcte control systems
IPC: H02J13/00
Filed: 1931-03-09
Abstract: 378,435. Electric signalling systems. WHITBY, E., 33, Cropthorne Court, Maida Vale, London, PEDLER, I. A. D., 5, Hampstead Road, Brislington, SELSTON, E. J., York House, Morley Road, Staple Hill, both in Bristol, and LESTER, L. R., Rest Harrow, Old Bracknell, Berkshire. March 9, 1931, No. 7221. [Class 40 (i).] In a remote control system for effecting at a distance operations such as the change over in multiple tariff meters, the actuation of switches, &c., the control currents or impulses are transmitted over a single phase or polyphase alternating current network and are derived from the network through a transformer. As shown in the Figure, the switch 1 of a transmitting device 2 is connected through the secondary winding 3 of a transformer 4 to the coil 5 of an impulse relay 6. The transformer 4 is supplied from one phase of a high-tension network 7. The relay 6 controls the primary of a transformer 10 supplied from the transformer 4, the earthed secondary of the transformer 10 being connected to the network through star-connected impedance coils 12. Instead of the coils 12, condensers may be employed. At the remote station B the high-tension network 7 supplies the low-tension feeders 20, and an impulse receiving relay 16 is connected to the network 7 through star-connected coils 14. The relay 16 controls the primary winding of a transformer 17 supplied from one phase of the lowtension network and the secondary winding is connected to the receiving devices R over the neutral conductor 22, an earth return being utilized. Instead of the earth, a cable sheath or an independent line may be employed. In stations having no neutral conductors, the control currents are transmitted over one or more phase conductors through artificial neutral points. Instead of supplying the transformer 17 from the network 20, it may be supplied from a network having a separate source of supply. Selective control of the devices R may be effected by transmitting characteristic numbers of impulses or impulses having characteristic durations. Instead of employing an impulse receiving relay at station B, a bridging transformer may be used to transmit the control impulses directly from the hightension side to the low-tension side of the network. The Provisional Specification states that control currents may be transmitted over a direct-current network, the impulses being derived from the network or a separate external source.

Abstract: 589,509. Fish-filleting machines. ATLANTIC COAST FISHERIES CO. March 22, 1945, No. 7292. Convention date, April 14, 1944. [Class 28 (ii)] In a fish-filleting machine in which side fillets are partly cut but still remain attached to the back-bone and ribs, the fish then being moved over a pair of fixed spaced ribbing knives 18 to effect final detachment as described in Specification 452,688, the fish is pressed down and moved along the ribbing knives 18 by a number of pusher fingers 44, mounted on blocks 42 pivotally secured at their end to a chain 40, each block having a pair of downwardly extending supports 46 providing at the top a passage in which the chain 40 is positioned, the pusher fingers 44 being pivoted to the inner surface of each support 46. The blocks are secured on the chain 40 by pins 122 engaging the boss 114 of one block with a pair of slots 100 of the next block, the slot allowing shifting of the block relative to the chain on passing round the sprockets 36, 38. When the chain 40 is horizontal, the surface 118, Fig. 2, rests on shoulder 102 of the block in front to hold their connections rigid, so that they cannot sag, non-sagging being also assisted if desired by the flanges 50 travelling on spaced fixed rails 130. A fixed cam guide 144, Fig. 1, acts on cam roller 82 to pivot the fingers 44 about 74, Fig. 2, so that they enter the flared portion 146 of the ribbing knives 18 and the fingers entering the belly of the fish, to press it down on the ribbing knives. As a fish passes to the left away from the below-belly slitting knives 10, a fixed cam 134, Fig. 1, acting on cam roller 82 pivots the fingers 44 so that they engage on each side of the backbone in the upper slit and in the pectoral cavity. The fingers then slide the fish along and down against the ribbing knives 18 during their lower horizontal run, to detach the fillets from the backbone and scrape the flesh from the ribs. At the end of this run, a fixed cam 146 acting on rollers 82 raises the fingers 44 out of the fish and keeps the fingers safely retracted as they pass round the sprocket 38. U.S.A. Specification 2,179,821 also is referred to.

Abstract: 127,680. Lanchester, F. W. May 25, 1917. Ballasting.-Relates to apparatus for automatically varying the buoyancy in order to maintain a given depth and consists in controlling variations of depth by the combined action of (1) a hydrostat, (2) an inertia or velocity-sensitive device, and (3) a damping-device. As shown in Fig. 1, a hydrostat J<4> is attached to a stem J<2> carried by springs J<3> and provided with a baffle plate J. The parts controlled by the springs J<3> constitute a device sensitive to the velocities of oscillations of the mine and the plate J exposed to the water constitutes the damping device. The combined action is transmitted to a piston valve J<6> controlling the inlets and outlet of two waterballast chambers B, C, Fig 4. The pressure within these chambers is maintained at a constant difference within limits, by means of an electrically-driven pump G, G<2>, G<4>, G<3>, the switch H<3> of which is controlled by this difference in pressure, the switch being on a rod H<4> connecting two diaphragms H<5>, H<6> exposed to the pressures in the chambers B, C respectively and balanced by a spring H<7>. The diaphragms H<5>, H<6> are dished so as to move to their extreme positions as soon as they pass their dead centres. This produces a rapid make and break, and also enables the motor driving the pump to run for a sufficient time before being stopped, thus ensuring efficient use of power,
