Title: An aircraft with ground effect type landing gear
IPC: B64C25/00
Filed: 1965-08-20
Abstract: 1,121,148. Air cushion aircraft undercarriages. BELL AEROSPACE CORP. 20 Aug., 1965 [17 March, 1965], No. 35762/65. Headings B7G and B7K. [Also in Division F2] An aircraft undercarriage comprises at least one inflatable bag 30 enclosing an air cushion beneath the fuselage 20. The bag is of resilient material and when uninflated merges into the fuselage contours (Fig. 12, not shown). It is inflated by ducted fans 26 driven by gas turbines (28, Fig. 8, not shown) and contains a peripheral slot 40 forming an air curtain. The slot contains a tube 42 which when uninflated is hat, closing the slot (Figs. 11 and 12, not shown) and which is inflated by air bled from compressors of the gas turbine engines (28) to open the slot. The jet forming the air curtain is given an inward velocity component by Coande effect on the tube 42, and the air cushion may also be supplied through an opening 54. Air is drawn into the fans 26 and engines (28) through louvred intakes 68 in the fuselage or through porous sections of the fuselage (Fig. 15, not shown) for boundary layer control. After take-off, the fan air may be diverted through a tail pipe (60, Figs. 13-16, not shown) by valves (64) to provide propulsive thrust. These valves may be arranged (Fig. 16, not shown) to act as ejectors so that air is drawn into the tail pipe from the bag 30 to help deflate the latter. The aircraft described has a relatively large bag (32, Figs. 3 and 4, not shown), beneath the centre of gravity, and a smaller bag 30 forwardly thereof. When landing, the rear end of the larger bag (32) may be grounded to brake the aircraft.

Title: Improvements in the manufacture and production of acetaldehyde from acetylene
Filed: 1933-12-27
Abstract: Acetylene or a mixture containing acetylene is converted in part into acetaldehyde by passage through a concentrated aqueous solution of a heavy metal salt, the concentrated aqueous solution of which shows an acid reaction; the residual acetylene, preferably after separation of the acetaldehyde formed, is then converted into acetaldehyde by catalytic reaction with steam.  The first stage may be conducted as described in Specification 313,864, [Class 2 (iii)], or 393,690; for example, the gas may be passed at a raised temperature and pressure through a concentrated aqueous solution of a salt of zinc, cadmium or chromium, the activity of the solution being maintained by filtration through active carbon or a bleaching earth; preferably, a portion of the solution is continuously withdrawn, filtered, and returned to the reaction vessel.  The second stage may be effected as described in Specification 329,867 or 332,635, [both in Class 2 (iii)].  In an example, products obtained by leading methane or natural gas through an electric arc are washed with gas oil to yield a mixture containing acetylene 15, hydrogen 70, and methane hydrocarbons 14 per cent, this mixture is led at 140 DEG  C. through a concentrated aqueous solution of zinc chloride, the water consumed being replaced; the acetaldehyde formed is removed by washing with water under pressure and the residual gas, containing acetylene 5, hydrogen 78, and methane hydrocarbons 17 per cent, is saturated with water vapour and led at 300--400 DEG  C., over a mixture of aluminium, tungsten and zinc oxides, the acetaldehyde formed being recovered by washing with water.

Abstract: 1454536 Amplitude modulation DEFENCE SECRETARY OF STATE FOR 7 Aug 1974 [10 Aug 1973] 38113/73 Heading H3R A balanced modulator comprises a phase switching circuit 1 including two alternative carrier signal paths 2, 3 differing by one or more odd carrier half-wavelengths, a switching arrangement 6-8 for rendering one of the paths effective according to the polarity of a modulation signal and an amplitude modulator 9 connected to the output of circuit 1. In operation, modulation pulses are applied to a sharp cut-off low pass filter 16 to produce a signal having a sin x/x waveform. This signal is applied via a limiting amplifier 8 to switch diodes 6, 7 alternately as to reverse the phase of the carrier applied to line 5. The modulation signal is also applied via a full-wave rectifier 12 and a differential amplifier 11 to vary the effective impedance presented by the diode 10 on the carrier wave, as to amplitude modulate it. A portion of the modulated signal is rectified at 14 and fed back to an input of amplifier 11 to ensure a linear modulation relationship. The switching circuit 1 serves to suppress the carrier component in the output signal. A doppler landing guidance transmitter may have each aerial of a linear array fed with signals from a separate balanced modulator, the modulators being all connected to a common carrier-wave source and to time sequenced modulation signal sources. In elevation guidance transmitters, the aerials may be connected to the modulators via delay lines.

Filed: 1928-12-27
Abstract: 327,142. Deutsche Goldund Silber- Scheideanstalt, vorm. Roessler, and Weiss, L. Dec. 27, 1928. Enamels.-In a process for obtaining highly dispersive oxides of tin, titanium or zirconium, suitable for use as turbidity agents for vitreous enamels and the like, soluble compounds of the metals are allowed to react in their normal condition or in the presence of limited quantities of solvents with substances capable of converting them into oxides, as for example alkaline lyes, steam, ammonia, or the like, and the oxides or hydroxides produced are heated in the case of pigments to 500-800‹ C., and turbidity agents to 900-1500‹ C., to convert them into a voluminous form. The initial reaction can take place either in the liquid phase or between the vapours of the reactants. If the reaction in the vaporous phase takes place above 600‹ C., the subsequent heating may be omitted. In examples (1) titanium tetrachloride in the form of vapour is allowed to react with superheated steam at 500‹ C. and the oxide formed is washed, dried and heated to 600-800‹ C. to produce a pigment; (2) zirconium oxy-chloride or a concentrated solution thereof is stirred with concentrated ammonia solution, the pasty mass diluted with water, and the precipitate washed, dried and heated to 1200‹-1400‹ C. and a turbidity agent obtained; (3) the vapour of stannic chloride is treated with superheated steam at 300‹ C. and the oxide product is washed, dried and heated to a little above 900‹ C. to produce a turbidity agent.

Abstract: 1311068 Moulding surgical pads SCHOLL MFG CO Ltd 10 Aug 1970 [13 Oct 1969] 38392/70 Heading B5A [Also in Division A5] A surgical pad comprises a sheet of thermo plastics foam having an affliction-receiving cavity pressed inwardly from one face. The pad is formed in a double action press employing dies heated by high frequency alternating current. The upper die 1 comprises a conductive backing 6 and a knife edged skirt 7 for blanking the pad. An insulating block 10 provides a backing for the heated probe 12 that moves up through the lower die 2, collapsing the foam and creating the cavity in the pad. Preferably the pads are made of plasticized polyvinyl chloride or polyurethane although several other thermoplastics are suggested. An adhesive 23 may be applied to the lower surface of the foam sheet before the pressing operation. Normally this adhesive will be destroyed in the cavity by the hot probe, this is preferable if the pad is used to protect open wounds. A thermally stable adhesive may be used that will survive the pressing. In this case medicament may be secured in the cavity. The lower surface of the foam is covered by a sheet of material 24 having a release facing to protect the adhesive until the pad is used. In addition the upper surface of the foam may be laminated with a vinyl sheet 20 or a layer of pile fabric 22 for decorative purposes. The lower die 2 may be covered with a dielectric buffer such as tetrofluoroethylene to prevent the pad adhering to the die, or the buffer may be in the form of a travelling belt carrying the foam sheet.
