Title: An aircraft of the rotating wing type
IPC: B64C27/04
Filed: 1959-02-12
Abstract: 861,407. Rotary wing aircraft. BLACKBURN GROUP Ltd., and BRADBURY, C. Aug. 11, 1959 [Feb. 12, 1959], No. 4948/59. Class 4. A rotary wing aircraft comprises a non- rotating structure including landing gear and pilots' accommodation and a vertical axle having an air intake housing at its upper end, and a structure rotatable on the axle and including a plurality of lifting blades and engines for feeding gases to propulsion nozzles on the blades. The Figures show a " flying crane ", the non-rotating structure comprising a fairing 4 and four undercarriage legs 1 (two shown) one of which supports a crew nacelle 6. A lifting cable 5 depends from winch mechanism not shown. The undercarriage supports a vertical axle 2 surmounted by a structure 7 with a forwardly facing air intake, feeding twelve engines 11 mounted on fuel or fuel and oil tanks 10, the engines and tanks being in a rotary structure 9 mounted by a bearing 8 on the axle 2. There are two engines for each of the six blades 13, each engine being connected by flexible ducting 16 to rigid ducting 17, to allow for pitch change movements of the blades. The engine exhaust gases discharge tangentially to the blade tip path through a cascade of vanes 18 desgined to act as nozzles. Each blade is mainly of steel, with a light alloy trailing edge. The engines may be gas turbines producing exhaust gases, or gas turbines, mono-propellant or bi-propellant liquid fuel turbines, or reciprocating engines driving compressors, or free-piston gas generators. The non-rotary structure is orientatable by servomotors on the rotary structure cooperating with a toothed ring on the non-rotary structure, the motors being accelerated or decelerated to rotate the non-rotary structure, The motors may be driven by gases from the engines 11.

Title: Improvements in or relating to methods of producing 3-keto-í~,-10(ª-)-methyl steroids
IPC: C07J75/00
Filed: 1959-02-13
Abstract: 3-Keto-D 4,6-10a -methyl-steroids are prepared by subjecting 3-keto-D 4,7-10a -methyl-steroids to isomerisation in a solvent which contains less than 1% by weight of water and which, if it is saturated with hydrofluoric acid gas at 18 DEG C. has an electrical conductivity of at least 10-4 Mhos-preferably exceeding 10-2 Mhos, while the isomerisation in the solvent occurs under the influence of a hydrogen halide present in the solvent to at least 60% of saturation value-preferably saturated, at the reaction temperature.  Suitable solvents are primary and secondary alcohols such as methyl, ethyl, propyl, butyl, pentyl, hexyl, propyl-2, butyl-2 and -3 and pentyl-2 and -3 alcohols.  The steroid reactant may contain an a - or b -methyl group at C13, and at C17 a saturated or unsaturated aliphatic hydrocarbon substituent such as a 17-side chain similar to that of ergosterol, a 17-side chain formed by the oxidation of such a side chain e.g. a chain formed by ozonolysis such as a radical of the formula -CH(CH3)-CHO, or a 17-side chain containing an aldehyde or carboxy substituent.  Furthermore, one or more of the hydrogen atoms at positions 9, 11, 16 and/or 17 may be replaced by functional groups, e.g. by hydroxy, esterified hydroxy, alkyl, acyl, hydroxylated acyl, keto or halogen substituents.  In the examples D 4,6,22-luminstatrien-3-one is prepared from D 4,7,22-lumistatrien-3-one, and D 4,6,22-pyrostatrien-3-one is prepared from D 4,7,22-pyrostatrien-3-one.  The conversion of D 7 - 10a  - methyl - progesterone into D 6-10a -methyl-progesterone is also referred to.  10a -Methyl-progesterone (lumiprogesterone) is prepared by hydrogenating the D 6-double bond of 3-keto-D 3,6-lumisterol and then degrading the side chain by usual methods.  3 - Methoxy-D 3,5,7,22-lumistatetraene is prepared by isomerising D 4,7,22-lumistatriene-3-one with hydrogen chloride in propanol-2 up to 20% saturation concentration in the propanol-2.  D 4,7,22-Pyrostatrien-3-one is prepared by the Oppenauer oxidation of pyrocalciferol.

Title: A process for preparing polymerisation catalysts containing phosphoric acid and silice-phosphoric acid and the application of these catalysts in the polymerisation of alkenes
IPC: C07C2/18
Filed: 1952-02-28
Abstract: Catalysts for the polymerization of alkenes are prepared by impregnating kieselguhr in the form of porous pieces with phosphoric acid and dehydrating the pieces without substantially changing the particulate character of the kieselguhr; the porosity of the kieselguhr is such that pieces which will pass a screen of 15mm. mesh, but will be retained on a screen of 2 mm. mesh, can absorb, per 100 gms., at least about 150 gms. of P2O5 in the form of pyrophosphoric acid at about 100 DEG -200 DEG C. Kieselguhr products known as Sterchamol and Mollerstein may be used, or a kieselguhr paste containing a boric acid or soda ash may be extruded or pressed, and the pieces hardened; higher porosity may be obtained by adding sawdust which is subsequently burned out.  Preferably the kieselguhr pieces have a strength such that a spherical piece of 7 mm. diameter is able to withstand a pressure of at least 0.5 kg.  Impregnation is carried out at 100 DEG -200 DEG C (preferably 150 DEG -180 DEG C) and dehydration at 200 DEG -900C (preferably 300 DEG -400 DEG C).  The final catalyst has a preferred phosphoric acid content, calculated as P2O5 of 60-80 per cent by weight, and a preferred free or water-extractable acid content of 10-20 per cent.  The catalysts may be used for the polymerization of propene to form motor fuels or propene tetramer, pentamer, or hexamer.

Title: Tensioning and severing tools
IPC: B65B13/02
Filed: 1977-02-09
Abstract: The installation tool is especially suitable for attaching binding means which require to be tightened and cut off. A tightening mechanism (11) is actuated by means of a toggle joint (14) which gives way when a predetermined degree of tightening is reached and then actuates a cutting lever (12). The binding means is thus cut through with reduced impact action. In addition, the tool is easy to actuate. The degree of tightening can be set accurately and reliably, and the binding material is delivered from the tool to a controllable extent. <IMAGE>

Title: Improvements in apparatus for controlling the distribution of materials
IPC: B65G47/51
Filed: 1947-02-24
Abstract: 628,336. Endless-belt conveyers. HALFORD, T. F., and BAILLOT, A. G. Feb. 24, 1947, No. 5360. [Class 78 (i)] [Also in Group XXXV] Apparatus for conveying for example foundry sand comprises a conveyer 1 and several hoppers 5a, 5b, 5c, 5d, 5e each associated with means 9a-9e for discharging material from the conveyer into the hopper, and control means causing each discharging means to operate in sequence to discharge material into each hopper in turn. Further control means may be provided which, when the level of material in any hopper falls below a predetermined minimum, causes the corresponding discharge means only to be operated and which, when the level in any hopper exceeds a predetermined maximum, prevents delivery to this hopper. The endless belt conveyer 1 conveys sand from a source 6 past ploughs 9a, 9b, 9c, 9d, 9e which divert the sand into the hoppers but may be raised when electromagnets 12a, 12b, 12c, 12d, 12e are operated, surplus sand passing to a receiver 7 whence it is returned to the source 6. Two probes, comprising stainless steel rods mounted in insulators of glazed ceramic material at the upper end of each hopper, project vertically down into the hopper to different extents. The body of the hopper is earthed so that when the material reaches the level of a probe it is earthed to change the mode of operation of a relay system (see Group XXXV) controlling the sequential operation of the electromagnets 12a, 12b, 12c, 12d, 12e. The probes are arranged to vary the bias on the grid of a thermionic valve, the bias being changed more when the material reaches the level of the upper probe than when it reaches the lower probe. In the anode circuit of the valve are two relays, one more sensitive than the other so that one is operated when the material reaches the lower probe and the other when the material reaches the upper probe. These relays after the mode of operation of a series of relays including one corresponding to each plough, the latter relays being operated sequentially by means including an automatically periodically operated twoway switch, the relays locking when operated until released by an automatically operating interrupter switch. The time for which each electromagnet is caused to lower the corresponding plough is determined by a corresponding electric time-delay device.
