Title: Improvements in relation to rotorcraft
IPC: B64C27/26
Filed: 1963-05-03
Abstract: 1,091,401. Rotary wing aircraft. HANDLEY PAGE Ltd., and A. A. BLYTHE. May 1, 1964 [May 3, 1963], No. 17680/63. Headings B7G and B7W. A rotary wing aircraft comprises a rotor mast 1 connected to a prime mover 8, means for pivoting the mast between vertical and stowed positions and for locking it in the vertical position, and devices 35 for engaging the outer parts of the blades and folding them about hinges to stowed positions. In Fig. 3, the prime mover 8 drives coaxial shafts 14, 15 through clutch 9, bevel gear-box 13, and main gear-box 6, the two gear-boxes being connected by a shaft having an axis 2 about which the gear-box 6 with shafts 14 and 15 can be pivoted by a jack 41 to a stowed position. Arms 35 on the aircraft, which may be operable as a road or marine vehicle, using prime mover 8, can be swung between the broken and full line positions, by motors 37. Conventional collective and cyclic pitch control is transmitted through linkages to spider 18, swash plate 17 and push rods 16, each linkage having a pivot 2 which in a predetermined position of the flying controls lies on axis 2. Each blade has a flapping hinge 4, see also Fig. 7, the flapping motion being limited by a collar 51 and abutments 50 in the blade root. When the blade is to be folded, its collar 51 is withdrawn towards the hub by a motor and linkage, Fig. 6 (not shown). When clutch 9 is disengaged, the blades are stopped when lying transversely of the aircraft by a cam mechanism, Fig. 10, on the outer shaft 14. Normally, spring biased plungers 63 are held clear of the cam 60, but during the stowing operation, the plunger housings 68 are moved radially inwardly by a motor (not shown) so that the plunger noses 63 engage the cam, and bring the shaft to rest with the nose engaged in recesses 62. The shafts 14, 15 are so connected through gear-box 6 that all rotor blades then lie transversely of the aircraft, and when the rotor is lowered, the blades are received in rollers (Fig. 3) mounted on members 35. To stow the rotor, the pilot sets the prime mover to idle, disengages clutch 9, and puts the flying controls in the predetermined position. A single control may then effect the following sequence. The members 35 are swung out to the full line position, a locking pin 39 is withdrawn by jack 40, the mast 1 is lowered by jack 41 so that the blades engage the rollers on members 35, the blades flapping hinges are freed, and the members 35 are swung back to fold the blades against the fuselage, which may have recesses to receive the outer parts of the blades. The completion of this sequence is indicated to the pilot. To prepare for flight, this sequence is reversed. The jacks and motors involved may be hydraulic, pneumatic, or electric. Two or more prime movers may be used together, each connected through a free wheel device to gear-box 6, so as to permit overrunning.

Title: Vehicle parking apparatus
IPC: E04H6/18
Filed: 1947-07-04
Abstract: 648,683. Handling and storing vehicles. PARK-O-MAT, Inc. July 4, 1947, No. 17733. Convention date, Feb. 25, 1944. [Class 78 (iv)] In an apparatus for parking vehicles in which a common carrier selectively transports vehicles to and from storage compartments, a vehicle transferring member is mounted on the carrier to move the vehicles into and out of the compartments and carries vehicleengaging means mounted for axial movement along and swinging movement about the longitudinal axis of the transferring member to engage and disengage the vehicle. As shown (Fig. 4), the vehicle engaging means comprises two pistons 47 sliding in a cylinder 46 and having oppositely directed piston rods 48 extending through glands 56 and bent radially at 52 to pass through slots 51 in the cylinder 46. The inner portions of the slots 51 are parallel to the axis of the cylinder 46 and are at the top of the cylinder, while the outer ends spiral round the cylinder through a right angle. Thus, as the pistons 47 are moved toward the centre of the cylinder 46 by admitting pressure fluid through conduits 53 and exhausting it through conduit 54, the bent extensions 52 of the rods 48 rotate from a horizontal position to the vertical position shown and then move inwardly to grip a vehicle between them. The cylinder 46 is mounted on a head 36, Fig. 6, mounted to slide on a carriage 26 slidably mounted in turn in a well in the floor 22 of an elevator adapted to deliver a car to any of a series of floors, on each of which a storage compartment 18 is disposed at each side of the elevator. To transfer a car to a storage compartment from the elevator, a motor 76 is operated to drive a winch 74 so, through cable 78 and pulleys 71, 72, 73 driving the carriage 26 into the compartment until it is stopped by stops 81, and then driving the head 36 further into the compartment. If the rods 52 are in their vertical positions during this movement they will extend upwardly from the well in the floor 22 of the elevator to push a vehicle thereon into the compartment. The rods 52 are then retracted and the head 36 and carriage 26 withdrawn. Electromagnetically released locks lock the head 36 and carriage 26 in position when they have returned to their central positions. All the controls-hydraulic and electricfor the elevator, pistons 46, carriage 26, head 36, and locks therefor, are disposed on a single operator's panel. Modifications are shown in which the elevator is sufficiently wide to serve more than two compartments on each floor, and in which the floor 22 is rotatable about a vertical axis to serve a series of radially-disposed compartments on each floor.

Title: Improvements relating to the purification of labile enzymes contaminated with hemolysiní¬o
IPC: C07K14/315
Filed: 1952-07-16
Abstract: Labile enzymes contaminated with haemolysin-O are purified by treating aqueous solutions thereof with a solution of cholesterol in an organic liquid protein-precipitant, removing the resulting precipitate, adding water and separating the insoluble cholesterol-haemolysin complex and free cholesterol from the enzyme solution; the amount of cholesterol should be sufficient to combine with all the haemolysin, i.e. at least 0.01 mg. (and preferably 0.2-2.0 mg.) per 10,000 Bernheimer units thereof; the temperature is kept below 5 DEG  C. throughout.  The process is especially applicable to enzymes obtained by bacterial fermentation, with or without preliminary purification.  The organic liquid may be ethanol, methanol, acetone or ether; another liquid may be added to increase the solubility of the cholesterol. Sufficient liquid protein-precipitant should be added to give a concentration of 5-60 per cent by volume; when the concentration is greater than 40 per cent the temperature should be kept below 0 DEG  C., and in general it is desirable to keep the temperature within 5 DEG  C. of the freezing point of the mixture.  By suitable control of concentration, ionic strength, temperature, pH and amount of organic solvent it is possible to retain some non-enzymatic protein material in solution when all the enzymes have been precipitated.  To ensure that all the haemolysin is in its reduced form it is desirable to add a mercapto compound before the cholesterol.  The cholesterol complex is often too fine to be readily separated from the reconstituted solution and it is therefore advantageous to add protamine (0.005-0.02 parts by weight of total N in the solution), thereby precipitating non-enzymatic proteins in addition; this method is described in Specification 715,572.  Examples are given of the purification of a mixture of streptokinase and streptodornase, with and without protamine treatment.
