Title: Improvements in and relating to the manufacture of finely divided preparations of calcium hydrate and added substances
IPC: C08K3/22
Filed: 1948-02-17
Abstract: Finely divided preparations consisting mainly of calcium hydrate or calcium magnesium hydrate are prepared by hydrating the corresponding oxide with an aqueous solution of a sodium salt of a sulphonated higher fatty alcohol.  Optionally other substances, inactive or weakly reactive to calcium oxide such as sulphur, silicon compounds, china clay, pigments, rosins or waxes, may be added at any stage of hydration.  According to examples: (i) calcium oxide admixed with sulphur is hydrated with a 5 per cent aqueous solution of sodium salts of higher secondary alkyl sulphates, such solution being known under the Registered Trade Mark "Teepol".  The sulphur may be wholly or partly replaced by D.D.T. hexachlorocyclohexane or naphthalene; (ii) calcium oxide is hydrated with an aqueous solution of sodium alkyl naphthalene sulphonates known under the Registered Trade Mark "Alkanol H.G." in which has been emulsified ethyl silicate.  China clay, or titanium oxide may be employed as the additive substance to produce white pigments for distempers and paint.ALSO:A reinforcing and filling material for rubber comprises sulphur or ethyl silicate incorporated at any stage in the hydration of calcium or calcium magnesium oxide with an aqueous solution of a sodium salt of a sulphonated higher fatty alcohol.  According to example (a) 95 parts of powder calcium oxide are intimately mixed with 5 parts of flowers of sulphur and the mixture hydrated with 35 parts of water containing 5 per cent of sodium higher secondary alkyl sulphates, and (b) 100 parts of freshly burnt quicklime are hydrated with 40 parts of water containing in solution 2 per cent of sodium alkyl naphthalene sulphonate in which has been emulsified 10 parts of ethyl silicate.ALSO:Insecticidal or fungicidal compounds are incorporated at any stage in the hydration of calcium oxide or calcium magnesium oxide with an aqueous solution of a sodium salt of a sulphonated higher fatty alcohol.  According to examples calcium oxide, preferably freshly burnt is mixed with sulphur, D.D.T., hexachlorocylohexane or naphthalene and hydrated with a 5 per cent aqueous solution of the sodium salts of higher secondary alkyl sulphates known under the Registered Trade Mark "Teepol."  The resulting finely divided powder can be dispersed in water and applied as a powder, spray or as a soil fumigant.

Filed: 1926-02-22
Abstract: 263,343. Stuebing, A. F., and Clark, F. H. Feb. 22, 1926. Closure members; seats.-A throttle valve for controlling the flow of superheated steam to locomotive cylinders and of the type comprising a main valve 1 with a balancing piston 18 controlled by a pilot valve 21 has an annular seating 3 loosely mounted on an annular flange 16 in the casing so as to be self-adjusting transversely; the annular seating 3 is provided with a plurality of depending guide lugs 19 to prevent the seating from displacement from its normal assembly with its support. The seating is formed of a material sufficiently thin in cross-section to provide high flexibility so as to conform under fluid pressure to the parts of its support and valve engager thereby. By this means the distortion due to steam pressure on the valve is greater than the distortion of the valve body resulting from temperature changes and external stresses. The main and pilot valves 1,'21 are operated in proper sequence by an oscillatable shaft 28 and link 26. To prevent rotation of the main valve a baffle ring 27 is provided to deflect the steam.

Driving-mechanism, spring.-Relates to clockwork powerful enough to drive recording mechanism, astronomical instrurnents, light-house apparatus, and the like. The power is derived from a spring barrel 1 and is taken from the intermediate shaft 3<11> of a train of wheels and pinions 2, 2<1>, 3, 3<1>, and 4, 4<1>, and a time-movement beginning with the wheel 10 is driven through bevel sun and planet wheels 6, 7, 11, the first being integral with the wheel 3 of the power-train. The arm 11<1> carrying the planet wheel 11 is pulled by a spring 13 which constitutes accordingly the immediate driving device of the time-movement, a second spring 16 or maintaining power being optional. With imperfect synchronism between the continuous rotation of the driver 6 and the intermittent advance of the follower 7, the arm is carried forward and, being furnished with a pad 12, acts as a brake on a wheel 5 upon the last spindle of the main train.

Title: Improvements in and relating to harmonic generators
Inventor: BOISSIERE EISNER VALETON DE
IPC: H04J1/06
Filed: 1966-02-07
Abstract: 1,121,186. Harmonic generating circuits. TELEPHONE MFG. CO. Ltd. 31 Jan., 1967 [7 Feb., 1966], No. 5259/66. Heading H3T. In a harmonic generator a sine wave input from transformer T1 is clipped by a network MR1-MR5 and used to switch transistors VT1, VT2 and hence a bi-stable circuit VT3, VT4, the pulse output from which is used to charge or discharge capacitors C2, C3 through an output transformer T2. The clipping by network MR1-MR5 enables the use of a larger input signal than is necessary to switch VT1, VT2 and hence, because of the clipping, only the steep edges of the input signal are applied to VT1, VT2, thus speeding the switching. Diodes MR8, MR9 isolate transistors VT3, VT4 from the charges on capacitors C2, C3 during the switching of bi-stable pair VT3, VT4, thus preventing a slowing of this switching process. The odd harmonics may be taken from one of the secondaries of transformer T2 through a level matching pad, and the even harmonics taken from the other secondary, through a full wave rectifier (composed of transistors connected as diodes) followed by a level matching pad (Fig. 2, not shown).
