Title: Improvements in and relating to the control of fluid flow along a solid boundary surface
IPC: B64C21/04
Filed: 1946-04-11
Abstract: 610,623. Boundary layer control. GOLDSTEIN, S., RICHARDS, E. J., and PRESTON, J. H. April 11, 1946, No. 11198. [Class 4] A solid surface intended to serve as the boundary of a fluid stream is provided with a transversely-extending slot facing downstream through which fluid may be injected downstream into the boundary layer tangentially of the surface, which is so shaped that the calculated potential flow velocity decreases abruptly in the downstream direction at a position substantially coincident with the slot and not upstream of it, the upstream velocity gradients being such as not to provoke boundary layer separation, means being provided for injecting fluid through the slot into the boundary layer at a velocity not less than that of the outside edge of the boundary layer immediately upstream of the slot. Fig. 4 shows a thick unsymmetrical aerofoil, the section of which is shaped to produce a discontinuity in the velocity distribution over the upper surface at a point 69.1 per cent of the chord from the leading edge, where a spanwise slot S is provided connected to a pump P for injecting air into the boundary layer. The symmetrical aerofoil section shown in Fig. 6 is shaped to produce velocity discontinuities at points on the upper and lower surfaces distant 80 per cent of the chord from the leading edge. Slots S1, S2, in communication with a pump P are located at these points, the upper one S1 being a suction slot and the lower one S2 a discharge slot through which air drawn through the upper slot is injected into the boundary layer on the lower surface. This arrangement may be modified by providing a discharge slot on both the upper and lower surfaces, the air being supplied to the slots through a single branched duct or two separate ducts. Fig. 8 shows the application of the invention to a symmetrical expansion duct with decreasing velocity in the downstream direction, e.g. for a compressor diffuser, in which downstream-facing injection slots S2 are provided in the portions of the wall W where the velocity q changes abruptly. Specification 578,763 is referred to.

Abstract: 290,971. I. G. Farbenindustrie Akt.- Ges. May 21, 1927, [Convention date]. Phosphorus.-Phosphorus may be produced from ferro-phosphorus by displacing the phosphorus from its combination with the iron, by the addition of silicon, which combines with the iron. The process may be carried out by fusing in an electric furnace, ferro-phosphorous with silicon or a silicon forming mixture such as silica and coke or carbon. The proportions may be adjusted to give a commercial ferro-silicon containing any desired quantity of silicon; the ferro-silicon is tapped off at intervals or continuously. The removal of the phosphorus may be facilitated by the introduction of inert gases, the phosphorus vapour evolved being subsequently condensed. According to the Specification as open to inspection under Sect. 91 (3) (a) sulphur or other substances may be used in place of silicon. This subject-matter does not appear in the Specification as accepted..

Title: Improvements in Grease Cups.
Inventor: ROHR WILLIAM JOHN
IPC: F16N21/06
Filed: 1919-05-07
Abstract: 136,089. Rohr, W. J. May 7, 1919. Grease cups.-The cap of a force-feed grease cup is furnished with a lid secured and released by rotating a handle which is also used to screw down the cap to expel the grease. The cap B has an inwardly projecting rim C furnished with an opening shaped as shown in Fig. 4, and the lid d is depressed at its central portion to fit into the opening. A handle m is riveted to plates h, i above and below the lid, and can be rotated to cause projections on the plate i to engage under the rim C. One of the projections comes against a stop p so that after securing the lid, continued rotation of the handle screws down the cap B. The thread at the lower edge of the cap B is mutilated so that the cap cannot readily be removed from the part A. The lid is secured against loss by a ring r fastening it to the cap B. On unscrewing the cap by means of the handle m, the handle yields when resistance is met, preventing the mutilated thread from becoming jammed.

Title: Arrangement for interception service
IPC: H04Q3/42
Filed: 1967-03-10
Abstract: 1,136,055. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. 10 March, 1967 [15 March, 1966], No. 11480/67. Heading H4K. In an automatic telephone exchange calls (e.g. dead number calls) to predetermined numbers are intercepted and a store is scanned until a corresponding number is found. Data relating to a new number and/or a digital representation of a message is then read out from an adjacent storage location. The store may be a magnetic drum or a core store. The digital representation of the message may be used for the automatic selection of a verbal message from a drum or tape recorder (Fig. 2, not shown), or may be displayed together with the old and new number on a cathode - ray tube and announced by an operator to the calling subscriber. As shown each subscriber is connected to the exchange by a line selector S. The contacts of the final selectors LV connect either to one of the lines via cross connections KK or to a relay set RF associated with the intercept system. Intercepted calls enable relay set RF, and selectors ES and RSS complete a connection to a register REGS, to which the called number is transferred. A selector EV makes a connection to a free operator position EXP. Each register REGS is selected in sequence at TRS and the number applied to a comparator CC while a first address portion of a drum store DM is scanned. When a match is found this number, a new number and a representation of a corresponding message are read out at AH1, AH2 and AH3 and entered in portions AM1, AM2 and AM3 of a readout register. After re-coding at KO1 KO2 and KO3 the data is transferred to portions BM1, BM2 and BM3 of a further register. A signal sent from the comparator CC via selectors TRS, RSS and EV enables a register REGH associated with the selected vacant operator position. If the data from the register BM1-BM3 is received by the register REGH is correct as shown by a parity check lines t4 and t5 are enabled clearing registers AM1- AM3 and BM1-BM3 and comparator CC ready for the next call. If an error has occured the registers AM1-AM3, BM1-BM3 and REGH are cleared and the drum is read again during the next cycle. Data entered in register REGH correctly is displayed on a cathode-ray tube KSR as described in Specification 1,087,456. The operator sends an appropriate verbal message to the calling subscriber.

Title: Detector and automatic volume control circuit for frequency modulation receivers
IPC: H03G3/22
Filed: 1942-08-19
Abstract: 559,535. Frequency modulation ; automatic volume control. PHILCO RADIO & TELEVISION CORPORATION. Aug. 19, 1942, No. 11665. Convention date, Oct. 17, 1941. [Class 40 (v)] In a frequency-discriminating detector circuit for the reception of frequency-modulated waves, the load resistances of the rectifiers are connected in series-aiding relation for D.C. voltage so as to provide a voltage suitable for automatic volume control, and are connected in a reversed relation for providing audio output voltages. The circuit may be arranged for the alternative reception of ampli'ude-modulated or frequencymodulated waves without switching. The I.F. wave in circuit 9 is applied bv the coils 3, 4 in phase opposition to the rectifiers D1, D2 and in quadrature phase by the tuned circuit 5 loosely coupled to the circuit 9. The load resistance 1, 2 of the respective rectifiers are connected in seriesaiding relation by a high resistance 10, 20 so as to provide at AVC a direct or slowly-varying voltage for regulating the gain of the receiver. The resistances 1, 2 are connected in opposed relation by an audio-frequency condenser 8 so as to provide the audio output voltage across the two cathodes of the rectifiers. When the circuit is required to receive amplitude-modulated waves, a circuit tuned to a much lower I.F. than the circuit 9 is connected in series with that circuit, and is coupled to a secondary tuned circuit connected between the coil 4 and the condenser 8. The AM signal is rectified by the diode D2 and appears across the resistance 2, and may be taken off at the same terminals as the FM signal, Fig. 3 (not shown). Specifications 181,799, [Class 40 (v)], 489,094 and 559,967 are referred to.

Title: Turbine
IPC: F01D7/02
Filed: 1958-04-11
Abstract: 874,601. Wind motors; centrifugal governors. GARRETT CORPORATION. April 11, 1958 [April 11, 1957], No. 11679/58. Classes 57 and 110 (3). The means for adjusting in unison the pitch of turbine blades, each of which is mounted on a rotor in a manner allowing the blade to rotate about an axis extending along its length but preventing movement along this axis comprises a flyweight whose centre of gravity moves away from the axis of the rotor against a restraint as the rotor rotates and which transmits movement to the blades through a cam and camfollower. Preferably there are two flyweights and the restraint is a torsion bar. The two blades 18 (Fig. 1) of a windmotor are rotatably mounted in the front portion 20 of the rotor frame 17 and have gear portions 42 meshed with a crown wheel 43 which is mounted in bearings 44 in the frame and carries a cam 47. Flyweights 55 are pivoted on diametrically opposite shafts 54 (Fig. 3) on the portion 20 and carry rollers 56 engaging the cam. The rear portion 21 of the frame comprises a hollow shaft 22 journalled in bearings 16 in the fixed casing of the driven member 11, e.g. an electric generator, and a torsion bar 50 coaxial with the shaft is splined at opposite ends to the cam 47 and to the shaft. The two portions of the frame are secured together by screws 25 passing through arcuate slots in the rear portion and may be relatively angularly adjusted, to preload the torsion bar, by means of tangential set-screws 52 on the portion 20 which abut lugs 51 on the portion 21. When the flyweights swing outwardly they cause the cam to rotate against the torsion of the bar and the crownwheel 43 to turn the blades 18 towards a feathered position. Set-screws 58 limit the outward movement of the flyweights.
