Filed: 1946-05-30
Abstract: 612,688. Rotary-wing aircraft. BRISTOL AEROPLANE CO., Ltd., and WOTTON, J. May 30, 1946, No. 16485. [Class 4] A control for adjusting the pitch of the blades of a sustaining rotor comprises a cockpit control member movable in two directions at right angles, a pair of articulated, converging rods jointed together and movable by the control member in one direction to pull or. push both rods, and in the other direction to pull one rod and push the other, and a connection between the rods and an element of the pitchadjusting mechanism to which the movement of the rods is applied to reproduce the control movements. The invention is shown applied to a training helicopter fitted with dual control columns 10, 11 mounted on a transverse torque tube 12, the columns having downwardlyextending members 15 connected together by a link 16, and also connected to converging push-pull rods 17, 18. The latter are connected by vertical links 38 to a second pair of converging rods 29, 30 which control the movements of a universally-mounted rod 26 carrying 'the pitch-control spider 23. Movement of either control column in a fore-and-aft direction moves both pairs of converging rods in the same direction, resulting in the rod 26 being tilted in'the fore-and-aft plane. Transverse movement of either column causes approximately equal movements in opposite directions of the push-pull rods, with consequent transverse tilting movement of the member 26. Collective pitch control is effected by a hand lever 42 and links 43, 44.

Title: Improvements in or relating to a process for producing synthetic rubbery compositions
IPC: C08C19/36
Filed: 1952-07-03
Abstract: Synthetic rubbery compositions are prepared by mixing a synthetic rubbery polymeric material comprising predominantly linear carbon chains to which are attached from 0.001 to 0.30 chemical equivalents by weight of combined carboxyl ( - COOH) per 100 parts by weight of polymer with an amount of curing agent sufficient to react with at least 1/10 of the carbonyl groups, the curing agent being selected from primary and secondary aliphatic and heterocyclic polyamines and their salts containing at least two amino- or imino-nitrogen groups and heating at from 100 DEG  to 450 DEG  F. until an elastic condition is produced.  The polymeric material may be prepared by any of the methods of Specification 707,425, and may be any of those specified therein. Preferred polymers are those of an open-chain unsaturated aliphatic diene (e.g. butadiene-1 : 3), of an alkyl ester of acrylic acid, which is then hydrolysed, of a mixture of an olefinically unsaturated carboxylic acid (e.g. methacrylic acid) with either of the above; specified are butadiene-sorbic acid copolymer, butadiene-acrylonitrile-methacrylic acid terpolymer, ethyl acrylate-acrylic acid-methacrylic acid terpolymer (this polymerization may take place in two stages) and ethylacrylate-acrylic acid-methacrylic acid-divinyl benzene tetrapolymer.  The mixing may be done in any conventional manner such as mill-mixing, preferably below 175 DEG  to 200 DEG  F.  Preferred curing agents are the polymethylene diamines and the polyethylene diamines, e.g. hexamethylene diamine, its carbonate and its borate and the preferred proportions vary from 1 to 30 per cent based on the weight of polymer.  The heating may be carried out until the product has properties comparable to metallocarboxylates (e.g. 150-300 DEG F.) or more drastically to form diamide- or imido-type cross-linkages (e.g. 250-450 DEG  F.).

[Also in Division G1] A radiation - sensitive arrangement for use in an X-ray dosimeter consists of two PN junction silicon diodes 2, 3 mounted in a common housing 5, e.g. of plastic within which a shield, such as a perforated tin plate 4, blocks part of the radiation which would otherwise fall on one of the diodes and also acts as a source of secondary radiation. In the complete dosimeter a switch can connect either of the diodes to a microammeter 12, Fig. 2 (not shown). The unshielded diode's output will depend on both the intensity and the spectral distribution of the radiation, but the effect of the shield on the other diode is not only to reduce its quantitative sensitivity but also to minimize its dependance on spectral distribution. Thus a comparison of the outputs of the two diodes provides some indication of the spectral distribution of the radiation: in particular the thickness of a copper plate which will stop half the X-rays (the so-called halfvalue thickness, which is dependent on spectral distribution) may be inferred from the ratio of the outputs of the two diodes.
