Patent GB-1080209-A (GB)
Title: Torsion joint or bearing
IPC: F16F1/40
Filed: 1966-02-28
Abstract: 1,080,209. Aircraft rotors. LORD CORPORATION. Feb. 28, 1966 [March 30, 1965], No. 8785/66. Heading B7W. [Also in Division F2] An elastomeric torsion joint, for use in connecting helicopter blades to a rotor shaft head and which is stressed in shear by the change in blade pitch and heavily in compression by the centrifugal load of the blade when it is whirling rapidly, comprises an annular elastomeric body 15 which is bonded to annular end plates 9, 10 and to shims 16 imbedded therein, the plates 9, 10 being secured respectively to a flange 11 on the stem 12 of a blade and to an inwardly-extending flange 13 on a cylindrical member connected to a rotor arm (3) through joints (5), (6), Fig. 1, not shown. Column instability, due to lateral shifting of the elastomer, is overcome by having the central sections of the shims of shallow frusto conical section 19, and the outer sections flat, perforations 25 being formed in the shims to equalize the elastomer. The bending load of the stem 12 is taken by bearings 26, 27 which allow relative axial sliding, and rotating, movements between the members 11, 14. In a modification a cylindrical elastomeric body (41), Figs. 7, 9, not shown, with metal shims (42) is bonded to annular end plates (37), (38) secured respectively to a U-shaped member (34) carried by a rotor arm (31) and a member (35), fixed to the blade (32), and having a pitch change linkage arm (36). A stabilizing metal pin (43) is bonded in the centre of the body (41). The sandwich joint of Figs. 7, 9, not shown, may be replaced by a joint according to Figs. 10, not shown, wherein the effective height (" H ") of the joint is reduced to such a low value compared to the outside diameter (" D ") of the elastomeric body that the problem of a buckling column is avoided. To this end the end plates (47), (48) have depending flanges (51), (52) which encircle annular flanges (54) adjacent end of the elastomer body (49). With a joint of rectangular section, because lateral instability only occurs in the direction of the width (" W "), a centre-pin (61) is only bonded into the elastomer along sides in the direction of the width of the body, Figs. 13, 15, not shown.

Title: Process of producing glucoheptonic acid and/or calcium glucoheptonate for the preparation of derivatives thereof
IPC: C07C51/487
Filed: 1953-03-31
Abstract: A solution of glucoheptonic acid containing 60-70 per cent of its calcium salt is obtained by reacting oxalic acid with calcium glucoheptonate in aqueous solutions so as to give a pH of 3.5-4.5 and allowing the resulting calcium oxalate to settle.  The clear solution is either further acidified, e.g. with oxalic acid to decompose the untransformed glucoheptonate or is completely neutralized to give pure calcium glucoheptonate by adding lime. Active carbon may be added to help decolorisation and the lactone may be obtained by freezing the solution of glucoheptonic acid. The calcium glucoheptonate may be obtained by treating glucose with calcium cyanide in aqueous media made alkaline by the addition of excess lime.  Ammonia, which is liberated, is driven off with steam or by boiling in vacuo.  Preferably excess of calcium cyanide is used.  The ferrous and magnesium salts are obtained by treating the solution with ferrous oxalate and magnesium carbonate respectively.

Title: Manufacture of sulphonation products
IPC: C07C303/24
Filed: 1937-03-31
Abstract: Sulphonated products stated to have foaming and washing properties are obtained by treating a hydroxyalkyl, polyhydroxyalkyl polyglycol or polyglycerol ether of an aromatic hydroxy compound together with an olefine having at least three carbon atoms, with a sulphonating agent followed, if desired, by neutralization.  In examples: (1) diisobutylene is condensed with phenylmonoglycol ether and with phenyldecaglycolether in the presence of sulphuric monohydrate; (2) phenylpenta-glycolether is condensed with isododecylene in the presence of oleum and with isohexylene in the presence of sulphuric acid, the product of the latter process is neutralized with ethanolamine; (3) cresylmonoglycolether, prepared from a mixture of crude cresols. is condensed with a mixture of olefines obtained by cracking petroleum; (4) o-cresylmonoglycerolether is condensed with isobutylene; (5) phenylhexa-glycolether is condensed with isoheptylene in the presence of concentrated sulphuric acid and the resulting mixture of mono- and diisoheptylphenylhexaglycolethersulphuric acid esters neutralized with ammonia or sodium carbonate.  Ethers of xylenols, naphthols, hydroxydiphenyls, hydroxyanthracenes, e.g. xylenyldihydroxypropylether, a  - naphthyl-polyglycerolether, and p-cresylpolyhydroxypropylether are specified starting materials. When impure olefines are employed, the paraffin hydrocarbons may be separated from the sulphonation products.  Samples have been furnished under Sect. 2 (5) of products prepared as follows: (1) naphthylpentapropyleneglycolether is condensed with isohexylene in the presence of methylenechloride and concentrated sulphuric acid; (2) phenyltrioxypropyleneglycolether is condensed with isododecylene in the presence of sulphuric acid and neutralized with caustic soda; (3) phenylheptaglycolether is condensed with octodecylene in the presence of sulphuric acid and the product neutralized and freed from inorganic salt by means of methanol.

Title: Methods and Apparatus for Trueing Wire-Spoked Wheels.

IPC: G01L1/10
Filed: 1968-02-26
Abstract: 1,197,853. Tensioning spokes. ATELIERS DE LA MOTOBECANE. 26 Feb., 1968 [27 Feb., 1967], No. 9227/68. Heading B7C. [Also in Division G1] In the trueing of a wire-spoke wheel by applying torque to each spoke nut to tension the spoke, the torque is applied in dependence on the natural frequency of vibration of the spoke. After initial pretensioning of the spokes, the wheel is fixed on a support 1a (Fig. 1) and an electromagnetic vibration exciter 5, detector 6 and a pneumatic wrench 3 for tightening the spoke nut 3a are provided for each spoke. A first exciter 5 1  previously energized by a pulse caused by the discharge of capacitor 7 when voltage source 91 is connected to fire thyristor 10, causes a spoke 2 1  to vibrate at its natural frequency, which is sensed by detector 6 1 , converted into a square wave signal of constant amplitude and fed to a comparator 20, where the frequency is compared with a reference frequency from an oscillator (not shown). If the tension in the spoke is below the desired value, a pulse is emitted by comparator 20, stretched in circuit 23 and, after a preset time delay provided by circuit 24 1 , is applied to the control 11 1  of pneumatic winch 3 1 . The tensioning of each spoke is carried out three times with increasing reference frequencies, so that the tensions finally lie within a narrow band corresponding to the highest frequency. The cyclic operation is effected by three switch banks A, B, C, driven by a motor 13, each having the same number of contacts 16, 19, 22 as there are spokes. The contacts on unit A for any one spoke are advanced by one in relation to the corresponding contacts on unit B so that while vibration of one spoke is being excited, the vibrations of the previously excited spoke are being detected and its tension adjusted, after a further slight delay at unit C. The cyclic operation may be effected electronically (Fig. 2) utilizing a pulse distributer 30 feeding pulses in sequence to pulse modifier 32, corresponding to unit A, and AND gates 33, 34, corresponding to units B, C. There are the same number of circuits 32, 33, 34 as there are spokes, and the gates 33, 34 for one spoke are energized by the pulse following that which is fed to the corresponding pulse modifier 32.
