Title: Improvements in or relating to timing mechanisms
IPC: F23Q9/02
Filed: 1926-11-06
Abstract: 272,756. Jackson, L. Mellersh-, (Sentinel Manufacturing Co.). Nov. 6, 1926. Clockwork actuation.-Controlling mechanism for a valve or switch comprises a two-stage setting mechanism of two concentrically moving pointers frictionally coupled to a time-movement, an operating shaft connected with the valve or switch, spring-controlled actuating means for the operating shaft, and releasing means controlled by the time-movement for segmental closing and opening of the valve or switch. The front and rear case-plates 15, 16 carry the movement plates 18, 19 of a time-movement comprising mainspring 21, main-wheel 22, ratchet 23, pawl 24, winding arbor 25, and a friction coupling 26 - -28. The squared end 30 of this arbor 25 passes through the plate 15 and a dial 31 secured thereto, and engages a squared opening 35 of the second-stage setting-pointer 34 and the squared opening 45 of the second-stage cam 44. The first-stage setting-pointer 33 is attached to a sleeve 39 which carries the first-stage cam 40 and which rotates freely on the part 30 of the winding-arbor. A spring 42 presses the cams 40, 44 together so that 40 is driven frictionally from the part 30 of the winding-arbor. These cams coact with a roller 47 on an arm 48 pivoted at 49 and having a hook 50 which coacts with two teeth 51, 52 on a flange 53, the tooth 51 extending farther from the axis of the flange than the tooth 52. This flange is integral with a sleeve 54 rigid on a shaft 55 which is connected with the valve or switch. Rigid with the shaft 55 is a hand-lever 56; a spring 58, Fig. 10, tends to move the shaft counter-clockwise, Fig. 1. A spring 71 presses the hook 50 towards the teeth 51, 52. If a housewife desired the gas-valve of a cooker, say, to be turned on and off one hour and four hours, respectively, after she has left the house, giving a cooking period of three hours, the first pointer 33 is set at " 1," second pointer 34 at " 4," and the lever 56 is raised to the position shown, where the hook 50 engages over the lower tooth 52. The counter-clockwise movement of the second pointer also winds up the spring 21. The device is now driven by the time-movement and for one hour the pointers 33 and 34 move together. When the pointer 33 reaches zero the first cam 40 moves the roller 47 and arm 48 so that the tooth 52 is released from the hook 50. The shaft 55 thereby turns counter-clockwise until the higher tooth 51 engages the hook 50, this movement turning on the gas. The pointers continue to rotate, and when the second pointer 34 reaches zero after another three hours, the second cam 44 moves the roller 47 further outwards, releasing the tooth 51 and allowing further rotation of shaft 55, which is thereby adapted to turn the gas off. A cushioning device is provided to minimize the blow between the parts 50, 51 when the tooth 52 is released.

Title: Improvements relating to artificial shaped structures
IPC: B05D3/06
Filed: 1959-08-18
Abstract: A plexifilament grafted polymer is made by subjecting a plexifilament formed from a synthetic organic fibre-forming polymer to ionizing radiation while it is in intimate contact with an organic compound. A plexifilament is defined as a three-dimensional fibrous integral plexus of synthetic organic fibre-forming polymeric material, the preparation of which is described in Specification 891,943.  The plexifilament may be made from an addition polymer of an unsaturated monomer (listed), in particular linear polyethylene or polypropylene, or from a condensation polymer, e.g. a plyamide, polyester, polyurea, polyurethane, polyoxymethylene, polyether, polyacetal or polysulphonamide.  The modifying organic compound is one in which a carbon atom is attached only to one or more of hydrogen, halogen, nitrogen, oxygen, sulphur, a radical containing a nitrogen, oxygen or sulphur atom through which the radical is attached to the carbon atom, or an organic radical, with the proviso that the carbon atom may not be doubly bonded to more than one sulphur or oxygen atom. Examples of such compounds are hydrocarbons, alcohols, acids, ethers, ketones, esters, aldehydes, isocyanates, sulphonates, mercaptans, thioethers, disulphides, nitriles, nitro compounds, amines, amides and halides, especially such compounds which contain ethylenic or acetylenic unsaturation (listed).  The ionizing radiation to which the plexifilament is exposed may be X-rays or particle radiation, e.g. accelerated electrons, protons, neutrons, alpha particles, deuterons or beta-particles.  The resulting products may consist of a backbone polymer to which are grafted (i) chains of a polymerized unsaturated monomer, (ii) chains of a preformed polymer, e.g. polyethylene glycol or polyacrylic or polymethacrylic acid, when such is used as the grafting compound, or (iii) single units of a grafting compound which is not homopolymerizable.  By the selection of an appropriate grafting compound the properties of the plexifilament may be modified in a desired manner, e.g. the dyeability, stability, wearing properties &c. may be improved.  The examples describe the grafting of acrylic acid, acrylonitrile, methyl acrylate, styrene and N-vinyl pyrrolidone on to polyethylene plexifilaments and acrylic acid on to a polypropylene plexifilament.  Reference has been directed by the Comptroller to Specification 820,120.

Title: Improvements in the production of organic sulphites
IPC: C07C301/00
Filed: 1946-09-20
Abstract: Organic sulphites are made by reacting an organic hydroxy compound with thionyl chloride and freezing the reaction mass while hydrogen chloride formed is removed, e.g. by evacuation. The freezing is brought about by rapid evacuation of the hydrogen chloride or by freezing by external means, e.g. solid carbon dioxide with or without acetone.  The reaction may be started at 0-15 DEG  C., cooled to prevent a rise above 20 DEG  C., and the reaction mass may be frozen just before the slow addition of a slight excess of thionyl chloride is completed.  The product may be neutralized with sodium carbonate or bicarbonate.  An example describes the reaction of n-decanol with thionyl chloride. Organic hydroxy bodies listed as suitable comprise straight-chain alcohols of 1-18 carbon atoms, ethyl lactate, triethyl citrate, benzyl alcohol, phenol, cresol, naphthol, xylenol, halogen and alkyl phenols.

Title: The antibiotic endomycin and process for its production
Filed: 1951-12-05
Abstract: An antibiotic endomycin, effective against bacteria, fungi and yeasts, is prepared by culturing Streptomyces endus NRRL 2339, the macroscopic and cultural characteristics of which are described, or a mutant thereof, in a nutrient medium preferably under submerged aerobic conditions at a pH 6.5-8.5 and a temperature of 20-30 DEG C., for 44 to 144 hours.  The nutrient medium contains a carbohydrate source, e.g. corn sugar, a nitrogen source, e.g. ammonium sulphate, soyabean meal, beef extract, peptone, brewers yeast and fermentation solubles, and inorganic salts, e.g. sodium chloride, potassium dihydrogen phosphate and calcium carbonate. The endomycin is mainly associated with the mycelium and may be extracted therefrom with an aliphatic alcohol of one to four C atoms, e.g. methanol, ethanol, propanol and butanol, and preferably 30-90 per cent. aqueous alcohol. The endomycin in the culture fluid may be obtained by alcohol extraction; but it is preferred to adjust the pH of the fermentation broth to 4-6, and especially pH 4.8, to render the endomycin insoluble and to filter it off with the mycelium, preferably with a filter aid.  The aqueous-alcohol extract is concentrated in vacuo, the aqueous concentrate extracted with a fat solvent, e.g. chloroform, petroleum ether and hexane to remove anti-foaming agent used in the fermentation, and then adjusted to pH 8-11, and preferably 8.5-9, with alkali metal hydroxide, carbonate or bicarbonate.  The filtrate is acidified with, e.g. acetic acid to a pH 3.5-5, and preferably 4.8, and the endomycin collected.  The endomycin may be further purified by dissolving in alcohol and adding a non-polar solvent such as ether, benzene, amyl acetate (preferred) or chloroform.  Endomycin is soluble in water at pH 7 or above or at pH 2.0 or lower; it is insoluble in water at pH 4-6.  Molecular weight 1300-1450, infra red absorption spectrum distinctive.

Title: Improvements in or relating to pre-payment mechanism for gas and the like meters
IPC: G07F15/00
Filed: 1938-10-01
Abstract: 516,956. Prepayment mechanism for meters. WILSON, J. H., and -WILSON GAS METERS, Ltd., G. Oct. 1, 1938, No. 28560. [Class 27] In prepayment gas and like meters the seating f against which the coin-controlled valve a is adapted to bear is capable of movement against the action of a spring h in the same direction as the closing movement of the valve. In the construction shown the valve a is carried by a push rod l and the seating comprises a sleeve f sliding in a socket g under the control of the spring. h. Stops f<1>, g<2> limit the movement of the seating. When a coin has been inserted a cam m on a gear-wheel n, driven by the prepayment mechanism moves under a pin o carried by a gear p and allows a spring s to open the valve, the gear p being free to rotate on the rod l but prevented from axial movement thereon. The meter mechanism rotates the gear p through a worm q, so that the pin o travels along the cam and finally closes the valve. If grit prevents the valve from bearing on its seating so that some gas still passes through, the seating slides in the socket g until the pin reaches the flat part m<1> of the cam. The additional rotation of the gear p and pin o will be proportional to the amount of unpaid' gas passed through the meter, and when next a coin is inserted part or all of the rotational movement given thereby to the cam will be employed in allowing the pin o to return to its normal position on the cam. The invention is also shown applied to a valve carried by an arm on a shaft. In this case the sliding movement of the valve seating 'is proportional to the amount of unpaid gas.

Title: Improvements in or relating to the reproduction of sound films
IPC: G11B7/00
Filed: 1936-10-21
Abstract: 475,835. Valve amplifying-circuits. KLANGFILM GES. Oct. 21, 1936, No. 28650. Convention date, Oct. 30, 1935. [Class 40 (v)] In recording sound on films the higher frequencies may be imperfectly recorded in the troughs or peaks of the waves giving an effect similar to the rectification of the waves and resulting in low-pitched interfering noise on reproduction. This defect is overcome in the reproducing-amplifier 2 by selecting the higher notes from its output by a variable condenser 5 connected to a transformer 6. The secondary coil is connected through rectifiers 8, 9 to a resistance 10, giving rise to a voltage across this resistance proportional to the varying high-frequency amplitude. A portion of this voltage is tapped off at 11 and is fed through a smoothing-circuit to the grid of the valve, where it counteracts the noise effect present in the input currents. A grid-bias battery 7 is connected between the mid-point of the transformer secondary and earth. The tapping 11 may be adjusted on either side of the midpoint, according to the nature and extent of the distortion in the record.

Title: Means for measuring servo shaft error
IPC: G05B23/02
Filed: 1957-09-11
Abstract: 824,465. Determining shaft position errors. COLLINS RADIO CO. Sept. 11, 1957 [Feb. 25, 1957], No. 28683/57. Class 40 (1). The average positional error of the output shaft 12 of a servo system due to spurious pulses is determined by a series of counters CB 1 -CB N  C 0  and CF I -CF N  connected to equally spaced contacts of a rotary switch 13, wiper arm 14 co-operating with the contacts being fixed to the shaft, and connected to a source of pulses 20. The first group of counters receives pulses when the shaft has deviated in a backward direction, the central counter Co receives them when the shaft is accurately positioned and the second group when the shaft is displaced forwardly. The summation of the products of the value in each counter and the displacement corresponding to that counter, taking forward deviation as positive and backward as negative, divided by the total number of pulses gives the average positional error of the shaft. The root mean square deviation may be worked out in a similar manner.
