Title: Improvements in or relating to friction driving gear for textile machines
IPC: D01H1/243
Filed: 1931-05-11
Abstract: 364,988. Collecting leakage oil from bearings. MASCHINENFABRIK SCHWEITER AKT.-GES., Horgen, near Zurich, Switzerland. May 11, 1931, No. 13905. Convention date, July 7, 1930. [Class 12 (i).] In a textile machine, such as a spooling machine, wherein a shaft 4 extending from a gear box 7 has secured thereto a friction disc 1 driven by a wheel 2, the hub of the disc 1 is formed with a funnel-shaped cavity 1a, the rim 1c of which is disposed within a recess 7a in the wall of the box 7, whereby oil leaking from the box along the shaft is trapped in the cavity la and is thrown from the rim 1c into the recess 7a, whence it returns to the box through ducts 8, 9. The diameter of the rim 1c is only slightly less than that of the recess 7a. Disengagement of the drive is effected by axial movement of a sleeve, 3 bearing against the disc hub through a ball bearing 6 and flanged rings 12, 13. A felt ring 11 arranged between the rings 12, 13 prevents passage of oil, which is led through radial holes 14 into the cavity 1a.

Title: Improvements in or relating to method of and apparatus for irradiating provitamin d
IPC: A61K31/592
Filed: 1944-07-21
Abstract: A method of irradiating provitamin D (for the production of vitamin D2, vitamin D3, tachysterol &c.) comprises agitating a provitamin D solution maintained at a temperature between room temperature and 50 DEG  C. while subjecting the solution to irradiation by ultra-violet light of a wavelength of 2500-3100 DEG  A.U. from a mantle-protected high-output ultra-violet source which is immersed in the solution. The provitamin may be ergesterol or 7-dehydrocholesterol and it may be dissolved in benzene, alcohol, ether, decalin, tetralin or toluene. Preferably, an inert gas such as carbon dioxide or nitrogen is introduced into the solution during the process.  The process may be carried out in an apparatus comprising a liquid-cooled container 13 of glass, earthenware, platinum, gold or enamelled metal into which the solution is introduced by a pipe 32, a mechanical stirrer 24, a pipe 28 for introducing <PICT:0617414/III/1> inert gas and a mercury arc 39 enclosed in a mantle 36 made of silica, "Corex" glass or like material which is transparent to ultraviolet light.  The arc may be cooled by passing air or the like through a side inlet 44 of a tube 43 which carries one of the arc leads 42, the air passing through channels in a positioning stopper 45 and out through a spacer 40.  According to modifications, several arcs may be used in one vessel and the arcs may be U-shaped or helical.ALSO:Vitamin D2, vitamin D3, tachysterol, &c. are prepared from provitamin D (e.g. ergesterol or 7-dehydrocholesterol) by agitating a provitamin solution maintained at a temperature between room temperature and 50 DEG  C. while subjecting the solution to irradiation by ultra-violet light of a wavelength of 2500-3100 DEG  A.V. from a mantle-protected high-output ultra-violet source which is immersed in the solution. Suitable solvents for the provitamin are benzene, alcohol, ethers, decalin, tetralin and toluene.  Preferably, an inert gas such as nitrogen or carbon dioxide is introduced into the solution during the process.  According to an example, solvent (benzene) is removed by vacuum distillation in an atmosphere of carbon dioxide at the completion of irradiation.  Unreacted ergosterol is recovered by repeated leachings with methanolether (2 : 1).  The residue is reacted with a pyridine solution of 3,5-dinitrobenzoyl chloride to convert it into the 3,5-dinitrobenzoate which is extracted with methanol after the removal of pyridine &c.  The dry residue is refluxed with acetone and on cooling the 3,5-dinitrobenzoate of vitamin D2 is crystallized out.  The ester is hydrolysed with methanolic potassium hydroxide to obtain vitamin D2.

Title: An improved method of and apparatus for the measurement and control of the average demand of an electric circuit
IPC: G01R11/66
Filed: 1933-05-15
Abstract: 421,402. Supply meters. DANCE, H. E., 6, Alexandra Road, Birkenhead, Cheshire. May 15, 1933. Nos. 14027/33, 16149/33, and 2132/34. [Class 37] Electricity supply demand is measured or controlled by main and interim demand integrating mechanisms operating with reference to two different time intervals, or by main and interim demand thermal meters having different temperature-time constants, the integrating mechanisms or meters, when an increase in the established demand is impending, actuating signals or load-controlling switchgear when the demands have a predetermined relationship. In one arrangement, Fig. 1, two demand mechanisms a<2> .. a<6>, b<2> .. b<6> include indicators a<7>, b<7>, the indicator a<7> leaving an arm a<9>, which connects with a further arm a<10>, in its maximum position from interval to interval. Contacts a<11>, b<11> on the members a<10>, b<7> connect at predetermined demand relationships and energize a relay circuit c<1>, c<2> to operate the control or signal apparatus. The magnitude of the increase in load is indicated approximately by a relay-operated contact drum the contacts being arranged in sequence to correspond with the interim integration periods, contact between the members a<11>, b<11> during a particular interval illuminating a particular lamp in a series. The integration period of the interim demand is preferably a fraction of that of the main demand so that a signal or control is effected some considerable time before the demand can be established at a level corresponding to the increased load. The main and interim integration mechanism can be operated by a single energy integrating meter. In a modification a mechanical integrating mechanism can be employed with a thermal demand meter having a temperature-time constant different from the integration interval of the mechanical mechanism.

Title: Process for the production of ammonium chloride and alkali sulphate
IPC: C01C1/16
Filed: 1925-06-02
Abstract: The double decomposition of a solid mixture of ammonium sulphate and alkali chloride is conducted in the presence of oxygen, chlorine, or chlorine dioxide.  Alternatively, substances may be added to the reacting mixture, which, under the influence of heat, produce these gases in situ.  In an example, a mixture containing sodium or potassium chloride, ammonium sulphate, and a small quantity of sodium peroxide or alkali nitrate, chlorate, persulphate, or hypochlorite is strongly heated, after a preliminary heat treatment, to remove any moisture.  Pure white sublimated salammoniac and, when sodium chloride is used, calcined sodium sulphate are obtained.  According to the Specification as open to inspection under Sect. 91 (3) (a), the decomposition may be effected in the presence of other oxidizing gases.  This subject-matter does not appear in the Specification as accepted.

Filed: 1937-04-06
Abstract: A food product is prepared by heating honey to pasteurizing temperature to destroy any yeast therein, cooling, allowing it to crystallize, mixing the crystallized honey with butter and homogenizing the mixture.  The honey may be heated to about 120 DEG F., strained, pasteurized by heating to 140-160 DEG  F., e.g. to 158 DEG  F. for 10 mins., quickly cooled to 90 DEG  F. or below, and finely crystallized seed honey is added.  The seeded honey is placed in containers and kept at a constant temperature between 40 DEG  and 60 DEG  F. until complete crystallization has taken place.  The crystallized honey and the butter, of which preferably 10-50 per cent is used, are mixed preferably by passing several times through a domestic meat grinder.  The mixture is finally passed through a homogenizer which may consist of three plungers and cylinders which act on it successively so that it is at a pressure of 1000-4000 lb. per sq. in. in the final cylinder from which it is abruptly discharged to a low pressure through a small orifice.

In Fig. 3, modulating signals from a microphone 1 and a carrier wave from oscillator 5 are supplied to a push-pull modulator 20 the output of which passes to a single sideband filter 21 and an adder 22 which restores the carrier. After the limiter 7 the signal passes through a filter 8 to the frequency doubler 18 and a filter 19 operating at twice the carrier frequency. The original signal is recovered in a single sideband demodulator 12 and passed through a filter 13 and adjustable attenuator and phase units 14 and 15 to the modulator 10. Preferably a dynamic control device 23 is included to vary a damping network 24 as a function (1+a<SP>2</SP>) of the amplitude a of the original signal. This could be applied in lead 27 or in the path leading to modulator 10 instead of where shown.
