Title: Improvements in blades for ducted axial flow machines
Inventor: GARDINER TERENCE EDWARD GOUVEN
IPC: F04D29/32

Abstract: 1,003,313. Turbine and like blades. BRISTOL SIDDELEY ENGINES Ltd. Nov. 16, 1961 [Nov. 17, 1960], No. 39550/60. Heading FIT. A blade assembly for an axial flow turbine or like machine comprises at least two fluid deflection blade parts, one radially outside the other and articulated together to allow relative pivotal movement. A gas turbine blade 1 has a tip shroud 4 carrying radial lugs 5, 6, 7, 8. A pin 16, retrained loosely in holes in the lugs by a washer 17, pivotally supports lugs 14, 15 .of an outer ducted fan blade 2 having an inner platform 13. A stop (not shown) limits pivotal movement of blade 2. Thrust washers 18 are mounted between lugs 5, 14 and 8, 15 respectively. Blade 1 is made from a high strength metal alloy such as an alloy of nickel, cobalt and chromium and blade 2 is made from an aluminium base light alloy, titanium, or a plastic material reinforced with glass fibre. The shrouds, platforms and lugs of circumferentially adjacent blades form annular rings. Projections 9 from lugs 5, 8 form labyrinth seal rings co-operating with rings 10 on adjacent parts 11, 12 of the stator. Cooling air may be directed on to the lugs. In a modification, a turbine blade or blades is or are pivotally mounted on the tip of a radially inner ducted fan blade by a pin or bulb and socket joint. In a further modification, the inner and outer blades 1, 2 work in the same gas duct and the outer blade may be of ceramic material. The assembly may be pivoted to the rotor hub. The construction effects vibration damping.

Title: Process for the production of n,n-dimethyl-d-glucosamine, its salts and acetyl derivatives thereof
IPC: C07H13/04
Filed: 1960-11-18
Abstract: The invention comprises 1,3,4,6-tetraacetyl-N,N-dimethyl-D-glucosamine and its salts prepared by treating 1,3,4,6-tetraacetyl-D-glucosamine with formaldehyde and hydrogen in the presence of a hydrogenation catalyst and in an inert solvent at room temperature, and isolating the product preferably as its salt.  Raney nickel, and platinum oxide or palladium on carriers such as charcoal, barium sulphate or carbonate can be used as catalysts and hydrochloric, hydrobromic, sulphuric, oxalic or maleic acids are added to form salts which are separated, and the base liberated therefrom if desired.  N,N-dimethyl-D-glucosamine may be formed by further hydrolysis with aqueous mineral acid e.g. 0.5-3N hydrochloric acid.  The compound may be reacted with acetylbromide to form a -bromo - 3,4,6 - triacetyl-N,N-dimethylglucosamine hydrobromide, which may be reacted with the sodium salt of o -benzylphenol or 2,6-dimethyl phenol to form 3,4,6-triacetyl - b  - (o  - benzylphenyl)-N,N-dimethyl-D-pyranoglucosaminide, which with ammonia in aqueous methanol forms b -(o -benzylphenyl) - N,N-dimethyl-D-pyranoglucosaminide or which may be reacted with methyl halides to form methohalides, or 3,4,6-triacetyl-b -(2161-dimethylphenyl)-N, N-dimethyl-D-pyranolglucosaminide which may be quaternised with methyl halides.

Title: Improvements relating to fluid pressure oscillators
IPC: F15C1/22
Filed: 1964-09-30
Abstract: 1,010,930. Fluid pulse generators. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 30, 1964 [Oct. 29, 1963], No. 39735/64. Heading G4B. A fluid pulse generator consists of a tuning fork 10 maintained in vibration by fluid pressure and gating a fluid pressure supply to produce the required pulses. The fork is maintained in oscillation by fluid from a nozzle 16 offset slightly from an opening 12 in one tine 10a. The other tine 10b carries a member 18 having a slot 20 lying between conduits 21 and 22 when the fork is at rest. Movement of this tine periodically gates the flow of fluid from conduit 21 to conduit 22, thus producing timed pulses. These are amplified by a bi-stable switch 24 producing pulses alternately in conduits 27 and 28. A delay 36-1 ensures a slight overlap in the pulses applied to an AND gate 34, the output of which thus consists of short pulses, e.g. of one millisecond at a frequency of one hundred per second. A switch 24-1 produces amplified pulses at T1. Further switches and delays will produce delayed pulses at T2 and T3. In a modification the conduit 16 is inclined relative to the opening 12 in the tine 10a. In the embodiment shown in Fig. 6, fluid from one of the output conduits 76, 78 of a bi-stable switch 70 acts on the tine 10b. Movement of this causes corresponding movement of the other tine which cuts off the flow of air at one of two orifices 59, 60 thus changing the flow in conduits 62, 64 and switching the output from the switch 70. The outputs from the switch 70 may also be used to operate further logical devices. In a further embodiment one of the tines of the tuning fork vibrates between two nozzles, the conduits to which can be adjusted in length to provide a resonant system. Various other systems are also described, one using a fluid Helmholtz resonator to provide the activation of the fork.

In operation a tap 14 is opened and a gas sample is drawn in by expanding a bellows 8 until the liquid level in the cavity 3 falls near to the zero mark on a scale 4. A spring loaded valve 6 is opened and the bellows is operated to equalise the liquid levels in the tubes 3, 5 and the scale reading is noted. A cock 12 is opened and the bellows contracted to force the gas sample into the absorption pipette 11 which contains an absorbent for one of the constituents of the gas mixture and is preferably packed with glass tubes or beads. The pipette is connected to a stoppered limp flexible reservoir 13 e.g. of polyethylene or polyvinyl chloride, and this allows all of the gas sample to enter the pipette 11. On completion of the absorption the bellows 8 is expanded to draw the gas from the burette and the cock 12 is closed just as the liquid in the pipette reaches its level. The liquid levels in the cavity 3 and 5 are again equalised with the valve 6 open and thus the volume of gas absorbed can be measured. Several pipettes 11 may be provided for successive determination of the different constituents of the gas mixture and instead of glass beads the pipette 11 may be provided with a spraying device actuated by squeezing the reservoir 13.

Abstract: 1481606 Ropes; braided fabrics ALLIED POLYMER GROUP Ltd 23 Sept 1975 [24 Sept 1974 14 March 1975] 41441/74 and 10666/ 75 Headings D1K and DIT A rope having at least one element of elastic material is characterised in that it is associated with strips, filaments or cords having a resilience that is low compared with that of the elastic material; the strips, filaments or cords causing the elastic material to be subjected to pressure when the rope is elongated or at least when the elongation exceeds a predetermined value and the volume and density of the element is such that the rope is buoyant in water. In Fig. 1 a thick walled tube 1 of rubber or the like has flanges 2 and 3 attached to its ends. Also attached to the flanges 2 and 3 is a sheath of braiding, one wire of which is schematically indicated at 4. The angle made by the wire 4 with the axis of the cylinder is marked X. If the angle X is less than 45 degrees, the radius of the helix will decrease more rapidly than the radius of the rubber, and the braiding will then tighten on the rubber. If in an untensioned rope the angle X is 60‹ then stretching of the rope will initially be resisted only by the rubber, with the braiding moving out of contact with the rubber. When stretching has reduced the angle X to 30 degrees the braiding will again be in contact with the rubber; and further stretching will cause the braiding to tighten against the rubber. Radial pressure of the braiding against the rubber increases the resistance to stretching of the rope. In a modified embodiment a sheath of braiding contains a line of rubber balls or bodies of non-cylindrical shape. In the condition of rest the braiding just touches the balls; when stretched the braiding contracts radially to compress the balls. In a further modification the rope comprises an elastomeric core that is reinforced by longitudinally extending support yarns. Extending helically around the core are nylon strands which, when the rope is stretched, exert a radial compression on the core. The rope may be in the form of a plaited or knitted web.
