Title: Improvements in and relating to aeroplane supporting surfaces
IPC: B64C3/00
Filed: 1920-07-12
Abstract: 152,308. Rumpler Luftfahrzeugbau Ges., E. Jan. 26, 1914. [Convention date]. No Patent granted (Sealing fee not paid). Planes, construction of.-The upper and lower surfaces of a plane are adapted to take stress and form the flanges of a cellular girder of which the spars form the webs. Fig. 3 shows a cross-section of a wing having spars 1 and ribs 2 connected by compound plates 3 which may be continuously extended to a leading edge 4, or these extensions may be in the form of tongues at intervals supporting a fabric covering 6. The coverings may also be extended in either manner to the trailing edge. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter : Fig. 4 (Cancelled) shows a modification in which the front spar b is placed adjacent to a nose-piece f and covered with compound plates of wood a, the upper edge of the covering being gradually reduced in thickness, as shown. Upper and lower members c, d extend from the rear face of the spar b. The usual fabric covering in this case may terminate at the covering a. The external covering may be of sheet metal secured by countersunk rivets. The fixed tail surface may be formed as a single plane without external bracing and threaded through a slot in the fuselage, the covering being several sheets of thin metal. Fig. 8 (Cancelled) shows an elevator or aileron having a rounded conical front edge formed by bending plates 33 over formers 31. A transverse piece of wood 34 with lightening-holes is placed behind the formers 31, and is strengthened by a thin strip of wood 36 with its grain running vertically. The plates 33 are also secured to ribs 37 and end pieces 39, 40. The front of the plane has T-shaped slots 41, 42 for the introduction and working clearance of connecting members 46 which turn on tubes 48 secured in blocks 44 by pins 49. The blocks 44 have peripheral lightening recesses 45, and a wood plate 43 reinforces the covering 33 where the slots 41, 42 are made. Steering and balancing.-The conical surface formed by the cover 33 co-operates with a similar concave surface on the adjacent plane so that the gap remains constant as the control surface turns about the axis of the tubes 48. A rudder having a hollow conical leading edge co-operating with a convex-edged plane is also described. This subject-matter does not appear in the Specification as accepted.

Abstract: 315,229. British Arca Regulators, Ltd., (Assignees of Arca-Regler Akt.-Ges.). July 9, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Mixing fluids in flow.-The consistency of the supply of a mixture, such as paper pulp, is maintained constant by supplying thereto a diluent, such as water, the supply of the diluent being controlled by the head of a part of the mixture circulating through a chamber with a discharge offering resistance to flow. In the form shown, the mixture contained in a vessel a is raised by a constant delivery pump c, the discharge from which is divided into two streams, one of which passes by the pipe e to a tank r, while the other stream passes by a pipe d to a chamber h which discharges by a swan neck g to the vessel a. The head in the chamber varies with the consistency of the mixture, circulating therethrough, and a float k controls a valve n for supplying diluent through a branch o by means of a device such as described in Specification 116,074*, [Class 96, Paper &c.]. The float may be replaced by a flexible diaphragm in the side of the chamber, or air may be forced through a pipe dipping into the mixture in the chamber, variations in the necessary air pressure, consequent upon variations in the head, operating the control device.

Title: Improvements in or relating to pulse train transmission systems
Inventor: DUERDOTH WINSTON THEODORE
IPC: H04Q11/04
Filed: 1954-07-21
Abstract: 819,631. Pulse modulation systems. POSTMASTER GENERAL. Nov. 4, 1955 [July 21, 1954],. No. 21327/54. Class 40 (5). In a telephone system in which amplitudemodulated, time division multiplexed pulse signals are transmitted by a coaxial cable, and in which the original unidirectional pulses are, at the transmitter, converted into pairs of pulses of opposite polarity, the receiver delays the leading pulse, inverts it in polarity and adds it to the second pulse of the pair. In order to reduce waveform distortion due to the cable, the waveform of the pulse pair may be deliberately modified at the transmitter, or the response of the receiver may be modified. At the transmitter, Fig. 3 (not shown), the unidirectional pulses are applied to a delay line which by reflection produces a pulse of inverted polarity delayed one pulse width, and this, added to the original pulse, provides the pair. At the receiver the pulse pairs are applied by a valve V3 to a similar delay line N1 and the output is taken from across the line via a rectifier W1. The first pulse of the pair passes only to the line N1 and the second pulse plus the reflected first pulse are passed as a single pulse of double amplitude by the rectifier W1 to the output V4. By adjusting resistor R6 (or the corresponding matching resistor at the transmitter) so as to produce multiple reflections of decaying amplitude, waveform distortion due to the coaxial cable may be compensated. In a further embodiment, Fig. 10 (not shown), the pulse pairs at the transmitter are produced by differentiation and using the resulting pulses to control a sin<SP>2</SP> pulse generation network. The sin2 pulses are of opposite polarity and overlap in time.
Patent GB-214987-A (GB)
Abstract: 214,987. K³ntzel, H. April 28, 1923, [Convention date]. Reciprocating-punch machines are combined with writing desks or devices for use with account sheets having perforations d, Fig. 4, at the edges to ensure registration of the printed matter on sheets superposed for duplicating. The sheets a are held on a writing desk e, Fig. 2, by a frame b pivoted to the desk at g and carrying a plate which marks the sheets up to the writing line. Each sheet is initially provided with two perforations, d at each edge engaging studs f on the desk in such position that the first line of the sheets is in the writing position. When the frame, b is lowered to hold the sheets a, a perforator h makes a third perforation i in the sheets which together with the nearer of the two perforations d is placed on the studs f for the second line of writing. A fresh perforation is made each time the frame b is lowered for a line of writing and the. studs f are always placed in the lower two perforations. The frame b is retained in a raised position by pawls k engaging ratchets m, the pawls being released when the frame b is to be lowered by turning a handle o connected by side rods to the pawls. To prevent tearing the sheets in handling, the studs f are lowered against the action of a spring r by a lever operated by a side key. Reference has been directed by the Comptroller to Specifications 104,563 and 112,742, [both in Class 100 (iv), Typewriters &c.], and 120,179, [Class 16, Books &c.].

Title: Method and apparatus for spinning filaments
IPC: B22D11/00
Filed: 1970-05-05
Abstract: 1317813 Continuous casting MONSANTO CO 5 May 1970 [6 May 1969] 21642/70 Heading B3F [Also in Division F4] A filament is produced by extruding a melt (e.g. of Pb/Sn alloy or Al, Cu or alloys of these melted in a crucible assembly 13, Fig. 1) having a viscosity of not more than 1 poise, through an orifice 31, Fig. 3, into an atmosphere containing a gas (e.g. for Pb/Sn alloy, O 2  or an O 2 /He mixture containing 10% of O 2  or of He) which reacts with the extruded stream, forming an insoluble film on it to stabilize it until it solidifies, the orifice 31 being frusto-conical for at least part of its length so that, despite the natural cross-sectional contraction of the initial stream 32 as indicated, the stream is intercepted by the orifice wall at a level below the orifice entrance and, at the orifice exit (which is shown in the particular case when it is at the interception level), the stream flows in contact with the wall and seals the orifice against the entry of the stabilizing gas. Once the interception contact is established the orifice fills with melt. The molten metals are non-wetting, i.e. they have a wetting angle of 90 degrees or greater relative to the material, e.g. alumina, of the orifice member 30. The orifice need not be radially symmetrical. Since, for a hypothetical inviscid melt, the minimum diameter to which a stream from a planar orifice would contact would be 0À78 times the orifice diameter, the frusto-conical orifice 19, Fig. 1, in an insert in a base 14 of the crucible assembly 13 has an exit diameter equal to or less than 0À78 times the diameter of the orifice entrance in order to intercept a stream of any melt. A charge of material is melted in the crucible 13 by a coil 20 and a susceptor 12 and is forced by gas pressure, through the orifice 19 and an aperture in a shelf 11 supported on a pedestal, into a stabilizing gas chamber 22. The distance L, Fig. 4, of the narrowest portion of the orifice from the orifice entrance need not be the length of the orifice since the orifice may extend below the narrowest portion as long as the extended region has a diameter no greater than the intercept diameter. As is evident, for interception, the angle α between a straight line 42 (joining corresponding points on the entrance periphery and the periphery of the narrowest portion) and the vertical 43, must be greater than an angle whose tangent is (X-S)/L where X is the entrance radius, L is the distance between the entrance and narrowest portion of the orifice and S is the radius of the stream at a distance L below the entrance. Since the orifice need not be radially symmetrical, the intercept angle α may vary around the orifice. Reference has been directed by the Comptroller to Specifications 1,153,577 and 1,197,972.

Title: Improvements in or relating to electrical pulse separating circuits
IPC: H04N5/073
Filed: 1943-12-24
Abstract: 582,330. Radiolocation; valve circuits. WATTON, W. L., BULL, E. W., and WHITE, E. L. C. Dec. 24, 1943, No. 21679. [Class 40 (v)] A pulse width discriminating circuit for separating single narrow pulses from wide pulses or series of pulses, comprises a main channel in which the pulses are delayed and an observing channel which derives control voltages to open the main channel to permit only single pulses of desired width to pass. Positive pulses such as a, b, c, d, Fig. 2, are fed to the grid of valve 7, Fig. 1, the output across the cathode resistor 10 being fed through delay network 11 and phase-reversing and limiting valve 12 to produce, at point Y, waveforms as shown at a<1>-d<1>, Fig. 3. Valve 7 is normally non-conducting and contains in its anode circuit resistors 16, 17 and capacitor 18 forming an integrating network. Applied pulses causing valve 7 to conduct, partially discharge capacitor 18, the time constant of the charging circuit being such that capacitor 18 reaches the full H.T. potential in the repetition period of the pulses. Single pulses of the desired width therefore produce at point X derived pulses a<2>, Fig. 4, of lesser amplitude than the pulses a<1>, whereas series of pulses or wide pulses produce derived pulses of greater amplitude as at a<3>. The pulses at points X and Y are fed to the grids of valves 19, 20 respectively which have a common cathode resistor 27. Valve 20 is normally fully conducting and pulses such as a<2>, which cause the common cathode potential to fall are insufficient to prevent pulses a<1> lowering the anode current of valve 20 and producing output pulses a<4>, Fig. 5, at the terminal Z, while pulses such as a<3> cause the cathode potential of valve 20 to be lowered to such a value that no output is obtained from Z. The circuit may be arranged to provide an output corresponding to wide pulses or series of pulses by reversing the polarities of the original and derived pulses and arranging for valve 19 to conduct only during the presence of a pulse such as a<3>. Preferably, however, the valves 19, 20 are replaced by a hexode, pulses at points X and Y being applied to different grids, pulses a<2> being insufficient to render the valve conducting while pulses a<3> permit the valve to conduct and produce an output. An alternative integrating circuit sensitive to amplitude and number of pulses but not their width is shown in Fig. 6. Negative pulses at the anode of valve 7 charge capacitors 28 and 30 in series through diode 29 to an extent dependent upon the pulse amplitude, the charge upon capacitor 30 decaying through resistor 31 in the pulse repetition period. At the end of a pulse, diode 32 conducts to discharge capacitor 28 and if before the discharge of capacitor 30 is appreciable, a further pulse is applied, a further charge is added to produce a derived pulse of stepped form and greater magnitude at X than that due to a single pulse.
