Abstract: 1470143 Centrifugal shaft coupling HITACHI Ltd 17 Feb 1975 [15 Feb 1974] 6629/75 Heading F2U In a centrifugal ignition advancer device for an I.C. engine in which a first spring 14 connected to weight 6 is of higher spring constant and lower initial tension than that of a second spring 15 connected to weight 7, the ignition can be advanced relative to the shaft 1 when the weights 1 are displaced in combination and when the first weight is displaced and the second weight is not displaced. As shown, the weights 6, 7 are pivoted at 5 on a plate 4 rotatable with the shaft 1 and are provided with stops 16a, 16b which rest against the shaft and pins 9, 10 which operated in slots 12, 13 to advance a plate 11 carrying a cam surface 2b. The slot 13 is made with clearances X and Y to allow movement of the plate 11 anti-clockwise by only the pin 9 after the speed N 2  has been reached. Upon speed N 4  being reached, the weight 7 moves but does not engage the sides of the slot 13. When speed N c  is exceeded the gap in the slot is closed and since the amount of displacement of weight 7 is greater than that of weight 6 the spring 14 of the weight 6 interferes with the displacement of weight 7 to cause a line H of smaller gradient than line L. At speed N 5  the pins 9, 10 are stopped by the ends 12W, 13W of the slots.

IPC: A61K38/22
Filed: 1930-02-28
Abstract: Therapeutically active albuminous substances are separated from aqueous thyroid extracts by addition of a saturated aqueous solution of ammonium sulphate or other easily soluble salt in a series of steps.  The extract is first treated with 40 to 45 per cent by volume of the saturated salt solution to precipitate inactive matter, which is removed and discarded, and then one or more further additions up to a total of about 80 per cent are made to precipitate active fractions.  The active precipitates are removed by filtration, freed from the precipitating salt by dialysis whereby the precipitates are re-dissolved, and the dialysate evaporated in vacuo.  Zinc sulphate, dimethylamine hydrochloride, diethylamine hydrochloride, or other easily soluble di-, tri- or tetra-alkyl-ammonium salts may be used in place of ammonium sulphate.  According to examples (1) an aqueous extract of the glands is treated successively with 45, 60, and 80 per cent by volume of saturated ammonium sulphate solution of the same hydrogen-ion concentration as the extract; (2) glands are extracted with water at a low temperature, the turbid juice obtained by percolation is clarified by centrifuging and treating successively with 40 to 45 and 60 per cent by volume of saturated ammonium sulphate solution.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of saturated salt solution up to 100 per cent by volume of the extract and includes examples according to which (1) frozen sheep thyroids are ground and extracted with water at 10 DEG  C., the extract is purified by percolation and centrifuging, and successive additions of saturated zinc sulphate solution are made up to a total of 70 per cent by volume; (2) an aqueous extract of pig's thyroids is treated first with 20 per cent and then with 60 per cent by volume of a concentrated solution of dimethylamine hydrochloride; (3) thyroids of cattle are extracted with water containing sodium chloride and the extract treated successively with 20 to 25 per cent and 70 per cent of concentrated diethylamine hydrochloride.  This subject-matter does not appear in the Specification as accepted.

Title: Light modulator

IPC: G02F1/33
Filed: 1967-02-13
Abstract: 1,113,917. Deflecting light. STANDARD TELEPHONES & CABLES Ltd. 13 Feb., 1967, No. 6748/67. Heading H4F. [Also in Division H1] A collimated beam 4, Fig. 1, of monochromatic light is deflected in a body 1 of transparent material having similarly stepped faces 5 and 6 by means of mechanical stress standing wave patterns in the ultrasonic range of frequencies, i.e. acoustic frequencies, set up by transducers 9 on steps 7, the body 1 acting as an acoustic resonator. The separation between faces 5 and 6 measured normally to the faces of the steps 7 and 8 is an integral number of halfwavelengths of a given centre acoustic frequency and the relative advance of the steps is equal to one wavelength at the centre frequency. At the centre frequency, line 12 represents the plane of the acoustic wavefront, and with beam 4 incident at the Bragg angle a, the beam is deflected through an angle 2α according to the Bragg reflection law of diffraction. When the acoustic frequency is varied about the centre frequency, the direction of propagation of the acoustic wave is altered to the right for a reduction in frequency and to the left for an increase in frequency. Thus by increasing the frequency of the acoustic wave to produce a new resonant state having a standing wave pattern front indicated by line 13 the beam of light is deflected through an angle 2α + 2#. The light beam is diffracted to within a certain resolvable angle which may exceed the angle between adjacent resonant states of the acoustic resonator in which case the control of the light beam may be quasi-continuous. To keep the Bragg angle in step with the direction of the acoustic beam over a range of acoustic wavelengths, it has been shown (A. Karpel et al, Proc. I.E.E.E., Vol. 54, No. 10, October, 1966, pp. 1429-1437) that a good choice of the pitch (d) of the steps is d = 2# a 2/# where # a  is the acoustic wavelength at the central frequency and # l  is the optical wavelength of the incident light beam in the body 1 which may comprise a crystal of quartz or sapphire. Typical dimensions of the crystal are given in the Specification. The resonator may comprise a single crystal of piezo-electric material such as quartz or lithium niobate, the transducer face of which is pressed against the inner conductor of a concentric transmission line, the other conductor of which being formed into a coaxial cavity, Figs. 2 and 3, not shown. The resonator may be shaped as a cylinder the opposed faces having parabolic sections with the same or different axes and foci, Figs. 4 and 5, not shown.

Title: Oxo synthesis and catalysts therefor
IPC: C07C27/22
Filed: 1958-03-04
Abstract: Olefines are formylated with a mixture of carbon monoxide and hydrogen at elevated temperature and pressure in the presence of a manganese polycarbonyl catalyst having the formula: RaMn(CO)y in which R is an alkyl, alkenyl, aryl, aralkyl or an acyl group or a cyclopentadienyl hydrocarbon radical, a is O or 1 and y is 3 or 5. Preferred temperatures for carrying out the reaction are in the range 75-300 DEG C. and preferred pressures are 100-300 atm.  Suitable catalysts are, for example, methyl manganese pentacarbonyl, ethyl manganese pentacarbonyl, sec-amyl manganese pentacarbonyl, dodecyl manganese pentacarbonyl, phenyl manganese pentacarbonyl, naphthyl manganese pentacarbonyl, toluyl manganese pentacarbonyl, tetramethylphenyl manganese pentacarbonyl, acetyl manganese pentacarbonyl, benzoyl manganese pentacarbonyl, propionyl manganese pentacarbonyl, tolmyl pentacarbonyl, allyl manganese pentacarbonyl, cyclopentadienyl manganese tricarbonyl, methyl cyclopentadienyl manganese tricarbonyl and indenyl manganese tricarbonyl.  The amount of catalyst used is preferably between 0,1 and 5% by weight of the olefine feed.  It is advantageous to carry out the reaction in the presence of a diluent which may be the olefine being formylated, the liquid reaction products or liquid hydrocarbons.  The manganese penta carbonyl compounds may be made by reacting phenyl magnesium chloride with manganous chloride in the presence of carbon monoxide to give manganese pentacarbonyl which on treatment with sodium gives sodium manganese pentacarbonyl; this may be reacted with alkyl halides, alkyl sulphates or acyl halides to produce the alkyl or acyl manganese pentacarbonyls.  If the acyl halide is aromatic thermal decomposition of the acyl manganese pentacarbonyl gives the aryl manganese pentacarbonyl. The cyclopentadienyl manganese tricarbonyls may be prepared by reacting cyclopentadienyl sodium with manganous chloride and treating the product with carbon monoxide.
