Title: Improvements in blades for helicopter rotors, propellers and the like
Inventor: CHEESEMAN IAN CLIFFORD
IPC: B64C27/46
Filed: 1968-05-20
Abstract: 1,244,621. Helicopter rotor blades; aircraft propellers. AVIATION SUPPLY. MINISTER OF. 15 May, 1969 [20 May, 1968], No. 23876/68. Headings B7V and B7W. [Also in Division F2] In a fibre-reinforced plastics aerofoil blade for a helicopter rotor or a propeller, a hollow spine member 1 extends substantially along the span of the blade and is provided with a root attachment 4, the spine member serving to conduct fluid to at least one aperture formed in the blade surface for discharge therefrom. A helicopter rotor blade with sections L 1 , L 2 , L 3  has a fibre-reinforced plastics sheath 2 formed around the steel spine member 1 and at the root end of the blade, sandwiched between an integral flange 3 of the spine member and a cover-plate 5, the flange, cover-plate and sheath being bolted to the rotor hub. Hightensile steel wires 9, to limit deflection of the blade, are riveted to the flange 3 and welded to the spine member near the tip. In order to modify the circulation around the blade and thereby provide added lift, pairs of axially extending slots through which air is discharged tangentially over the blade surface, are formed by prefabricated structures in cut-away portions of the sheath 2 in the sections L 1 , L 2 , L 3 ; for example, the slots 15, 16 in the section L 3  are formed by an axially extending strip (11) Fig. 5 (not shown), and a moulding (12) between which a convoluted plate (13) is attached by webs to the moulding. A flow distributer 42 supplies air through a duct 46 to the spine interior and to a plenum chamber 41 connected to an annular passage 8 formed in the coverplate 5 and to the first pair of slots (39), (40), Fig. 2 (not shown). The spine interior is divided into two passages by a baffle 47 along part of its length, the right-hand passage being blanked off at the end of section L 2  and the left-hand passage communicating with the spine interior in the section L 3 . Slots 30, 31, Fig. 3, are connected by holes to the right-hand passage; similarly, slots (21), (22) which are continuous with slots (15), (16), Figs. 4, 5 (not shown), are connected by holes to the spine interior in the section L 3 . The fibres may extend longitudinally of the blade, the sheath being applied in the form of laminations of plastics impregnated woven fibres of glass, boron, silicon, iron or alumina, heat-cured and bonded to the steel spine. In a modification, the slots are defined in liner sections, either integral or in the form of complimentary shaped components, inserted into grooves cut in the sheath.

Abstract: 958,806. Excess current protection. J. LANGHAM THOMPSON Ltd. June 26, 1962 [July 4, 1961], No. 24091/61. Heading H2H. [Also in Division G3] In a voltage regulator of the series transistor type comprising input terminals 10, 11 and a series transistor Trl, the conductivity of which is automatically controlled, over a voltage reference and comparison device 14 and a further transistor Tr2 to maintain a constant voltage at output terminals 12, 13, there is provided a third transistor Tr3 which operates to protect the regulator under fault conditions by cutting-off transistor Tr1. Transistor Tr3 has its base connected to a potential divider R4, R5 across the input terminals 10, 11, its collector connected over a switch S1b to the base of transistor Tr2 and its emitter connected to the emitter of transistor Tr1. Under normal operating conditions, the emitter of transistor Tr3 is more negative than the base and the transistor is cut-off; if, however, the output voltage at terminal 12 falls, under fault conditions, below the base voltage of transistor Tr3 as determined by potential divider R4, R5, the emitter of Tr3 becomes less negative than the base and transistor Tr3 conducts to cut-off transistor Tr2 which in turn cuts off the series transistor Tr1 to protect the circuit. When the fault has been removed, the circuit can be reset by operating switch contacts S1b and S1a. The input voltage may be a rectified alternating voltage and the device 14 may include a Zener diode and a fourth transistor (Fig. 2, not shown).

Title: Improvements in and relating to a process for manufacture of electric discharge devices
IPC: H01J7/18
Filed: 1933-08-30
Abstract: 424,787. Discharge apparatus. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, and FAIRBROTHER, J. A. V., 110, Eastlands Road, Rugby. Aug. 30, 1933, No. 24094. [Class 39 (i)] The formation of deposit on the envelope during outgassing or activating is prevented or the deposit is removed by vaporizing the deposit-forming material in the presence of a reducing material, such as hydrogen which is gaseous at ordinary temperatures and after combination exhausting the gaseous products of the reaction. It is stated that in manufacturing mercury vapour lamps with tungsten cathodes an oxide deposit is formed on the envelope. After evacuation and bake-out, the reducing gas is admitted and the cathodes heated to liberate the deposit-forming substance. After liberation, the gaseous products and any unoxidized reducing materials are evacuated. If the deposit is first allowed to form, it is vaporized by heating the bulb to a point just below its softening-point. In both cases the process is preferably carried out at a temperature just below the melting- point of glass.

The plate 46 is then withdrawn to allow the member 44 to descend further and push the sleeve over the neck. The sleeve is of thermally contractile synthetic resin so that the bottle may be conveyed to a heating station 51 where the sleeve is shrunk to grip a cap previously applied on the bottle neck. The sealed bottles are finally transferred to a rotary table 52. Infeed of bottles is from a rotary table 1 to a main conveyer 3 on which a worm 4 spaces them before they are engaged by a feed rotor 5. Alternate ports 30 of the suction rotor 29 engage sleeves 31 of a respective magazine 32 and transfer them to the ports 34 of fingers at the lower end of tubes 33 which are pivoted in plates 18, 18a of a rotary frame 17. Tubes (33a) are cam-operated both to rotate and to move axially so that ports (34a) engage each sleeve, and gears 36, 36a, Fig. 9, cause corresponding rotation of tubes 33. A cam-operated arm 35 then causes separation of the ports 34, 34a, while they hold opposite parts of each sleeve, thus opening the sleeve, Fig. 4 (not shown). The guide rods 39 and pusher members 44 are also cam-operated.

After the dye has been applied to the fibre the pH of the dyebath may be increased above 8, preferably 9-10, by adding an acid-binding agent or the dyed goods are aftertreated in a fresh bath at this pH.  The dyebath and after-treating bath preferably contain a neutral salt, e.g. sodium or potassium chloride, sodium sulphate or calcium chloride.
