Title: Improvements in and relating to preparations for use in contact with the teeth
IPC: A61Q11/00
Filed: 1948-03-11
Abstract: Preparations for use in contact with the teeth and which depress the solubility of tooth enamel in acids, comprise an aqueous solution of an alkali metal or ammonium salt of a fluoride complex of a Group IV element of the Periodic Table having an atomic number from 22 to 72 inclusive, the said salt being stable in water and soluble therein to the extent of at least 0.05 per cent at 70 DEG F, and a flavouring material.  Such fluoride complexes include potassium fluotitanate, fluohafniate and fluorgermanate, ammonium fluozirconate, sodium fluostannate and lithium fluozirconate.  Flavouring materials include salt, sugar, saccharin, vanillin and essential oils such as peppermint, spearmint, cinnamon, anise and clove.  The preparations may be in the form of tooth paste, tooth powder, liquid dentifrice, mouth wash or chewing gum.  Preferred concentration of fluoride complex in such preparations is 0.2 to 2 per cent, except in the case of the mouth wash in which 0.1 to 1 per cent may be employed.  The tooth preparations contain a non-toxic cleansing agent, which is stable in aqueous solution below pH7, and an abrasive such as calcium sulphate and pumice, such materials being compatible with the fluoride complex.  Suitable cleansing agents are water soluble alkyl sulphonates, e.g., sodium lauryl sulphonate; salts of high molecular weight, mono-fatty acid esters of lower molecular weight, hydroxy alkyl sulphonic acids, e.g., sodium salt of the coconut oil, fatty acid monoester of 1,2-dihydroxy-propane-3-sulphonic acid and the oleic acid ester of the sodium salt of isethionio acid; salts of high molecular weight fatty acid amides of lower molecular weight amino alkyl sulphonic acids, e.g., potassium salt of oleic acid amide of N-methyl-taurine; salts of high molecular alcohol esters of sulphocarbonylic acids, e.g., sodium salt of the lauryl alcohol ester of sulphoacetic acid; salts of lower molecular sulphocarbonylic acid amides of alkylolamine amine esters of high molecular weight fatty acids, e.g., sodium salt of the sulphoacetamide of amino ethyl laurate; higher alkylated aromatic sulphonic acids, e.g., potassium salt of the sulphonic acid derived from the condensation product of benzene and a chlorinated kerosene fraction containing predominately 12 carbon atoms per molecule; ethers of higher molecular weight alcohols and lower molecular weight hydroxysulphonic acids, e.g., monolauryl ether of 1, 2-dihydroxypropane-3-sodium sulphonate and monolauryl ether of the sodium salt of isethionic acid; non ionic alkyl or alkyl-aryl polyglycol ethers (see Specification 380,431). Where the preparations can be buffered at not lower than pH6 without precipitating the fluoride complex sulphuric acid ester detergents may be employed.  In the examples the compositions for a liquid dentifrice, mouth wash and topical application respectively contains ethyl alcohol, while a tooth paste contains glycerin and tragacanth, in addition to a selection from the above ingredients.

Abstract: 1,099,038. Automatic gramophones. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 22, 1965 [Feb. 24, 1964]. No. 7544/65. Heading G5R. The cam disc 35 controlling the cycle of an automatic gramophone is driven from a motor shaft 28 by an idler 32, Fig. 4, carried on a plate 34 which is rotatable about a shaft 33 and is biased by a spring 34a, Fig. 6, towards a position where the idler 32 is disengaged. In the disengaged position a pin 62 on a slidable bar 61 enters a notch in a cam groove 63 on cam disc 35 and holds the plate 34 in position by. its engagement with abutment surface 72 on the plate. When a start button 38 is pressed the plate 34 is rotated to the engaged position and the pin 62 moves out of the notch into the circular part of groove 63 and holds the plate 34 in the engaged position by its engagement with abutment surface 68. The groove 63 may be provided with a portion 70 causing inward movement of the bar 61 which operates a recorddropping mechanism. After one rotation of the cam disc 35 the pin 62 re-enters the notch in groove 63 and allows the plate 34 to rotate to the disengaged position. At the end of a record the plate 34 is rotated by an actuating mechanism to start a new change cycle. Tap-tap mechanism. One end 50, Fig. 4, of an actuating rod 45 forms a ring embracing an eccentric boss 53 on the underside of the turntable so that the hooked end 51 describes an ellipse as the turntable rotates. One arm of a control lever 46 pivoted to plate 34 carries a hook 58 and the other arm 57 co-operates with an arm 47 frictionally pivoted to a lever 44 which rotates with the pick-up arm. With the normal movement of the pick-up arm, the hook 51 strikes the edge of hook 58 and rotates the lever 46, so causing arm 47 to pivot.

Title: Improvements relating to folding tables or seats for use on motor vehicles
IPC: B60N3/00
Filed: 1929-03-11
Abstract: 321,135. Auster, Ltd., and Lane, P. March 11, 1929. Folding seats; rests, foot.-A folding seat or table for use on vehicles is adapted when not required, to be collapsed into a tray or base and used in an inclined position as a foot rest. The invention is described in connection with tables which are modifications of that described in Specification 310,651. The table shown in Fig. 1 is disposed behind the front seats of a vehicle, and the top 5 is supported at each end by two pairs of toggle-like links 1, 2 above a shallow tray 3, hinged to the floor, into which the table collapses. The table is divided longitudinally into two halves 4. 5, Fig. 3, which lie one over the other when the table is collapsed. The legs 1, 2 are maintained in their extended positions by the bars 17 &c. shown in Fig. 1. The links 2 are extended upwards beyond their pivot joints 11, and are connected, at the left-hand side, by links 13<a> to a lever 15, which is pivoted at 16 to the links 1 and pivoted also to the bars 17. At the other side the links 13 are longer, and are connected by a cross-bar 18 forming a handle, by means of which the parts are moved. On the bars 17 are spring catches 20 which engage with pins 19 on the links 13 and hold all the parts rigid. Lugs 21 on the links 1 prevent the levers 15 from falling too far. The catches 20 may be omitted. When the table is raised, the top is unfolded. For this purpose the part 5, Fig. 3, is raised on links 24 pivoted to framing 6, and turned down until the links are supported by pins 25, projecting parts of the strips 22 engage under other studs 26 on the framing 6, and hold the parts 5 in the same plane as the part 4. To provide additional support a draw-out frame 28, Fig. 1, may be fitted under the part 4. When the table is collapsed, the tray 3 may be turned up so that its underside, which may be covered with rubber, may be used as a foot-rest. To facilitate this, the tray is provided with extensions 31 pivoted to semi-circular slotted plates 33 mounted on the outer ends of sliding rods 37 each adjustably secured in a sleeve, 38 by a screw 41. The table is turned up to a suitable inclined position and secured by screw-and-nut fastenings 36. Handles 42 are fitted to facilitate the lifting of the table. In a modification, Fig. 10, the extensions 2a of two diagonally-opposed links 2 are inwardly cranked, and their upper ends engage with leaf-spring catches 43, which retain the table in its opened-out position. A hook 48 positively retains the parts in that position. A sliding member 49 has pins 29 adapted to engage with holes in the frame 6 and hold in the parts in their folded-up position.

Filed: 1950-03-30
Abstract: 691,316. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd., BEESON, E. J. G., and WEBB, A. A. March 6, 1951 [March 30, 1950], No. 8004/50. Drawings to Specification. Class 39(i). Each electrode of a discharge lamp has a tip in the form of a cone with a hemispherical end, said tips facing each other; the electrodes are of tungsten containing 3-5 per cent thoria, and may be massive, or slender rods. The lamp is of the compact source type with an electrode spacing of 3-5 mm., and is filled with a rare gas, e.g. xenon, possibly admixed with hydrogen, at ¢-2 atmospheres. With a xenon filling, the pressure is such that 2000 volts D.C. will not cause the discharge to strike until a pulse is applied to a starting electrode. The discharge may be continuous or an intermittent flash, and owing to the shape of the electrodes is localised at the tips, so that its path is always constant; thus the lamp can be accurately located relatively to an optical system.

Title: New or improved means for the production of castings
IPC: B22D47/02
Filed: 1949-03-25
Abstract: 674,234. Foundry plant; moulding-machines; moulding processes. WALLWORK & CO., Ltd., H., and WALLWORK, C. M. G. June 26, 1950 [March 25, 1949], No. 8166/49. Class 83 (i). Plant for the continuous production of castings comprises a continuous track around which flasks are carried past means for automatically opening or separating the two parts which travel side-by-side past sand-supplying means, through a moulding machine and past means for automatically closing the mould and a metal-pouring station, over a cooling track, and past a knock-out station, the cycle then being repeated. The flasks 20 each comprise halves 10, 11, Fig. 4, hinged together at 14, the part 10 having a roller 15 and the part 11 a spring clamp 17. The flasks 20 are fed from the point A by an intermittently-advanced chain conveyer 22, Fig. 2, past a helical rail 23 which engages the rollers 15 and opens them, then below false flasks 24 carried by a conveyer at the same speed as the conveyer 22 so that one flask 24 is applied to each part 10 and 11. They then pass below a sand hopper 28, which fills them, a press ram 31, which consolidates the sand adjacent the walls or at any re-entrant point on the pattern, a facing-sand hopper 34, which again fills them, and a pattern 36 of the moulding-machine 35 which is pressed into the sand. The false flasks are then removed by their conveyer and the moulds pass to a conveyer 37 by which they are carried past a helical rail 38 which closes the mould parts. The closed moulds pass to the pouring station where, say, six moulds are filled with molten metal from pots 39 filled from a ladle 40 carried from an overhead track 41. The filled moulds pass along a cooling track 42, Fig. 1, to the knock-out station 43 where they are vibrated over a grid which passes the castings to tables 44 while the sand is carried by a conveyer 46 past a magnetic separator 47, Fig. 2, to a hopper 48. Sand drawn from this is aerated and carried by a belt 49 to a mixer 50 from which it is carried by a conveyer 51 to the hopper 26. Facing sand from a mill 52 is carried by a conveyer 53 to the hopper 32. Cores may be inserted if required. The pattern 36 and table may have co-acting projections to form runners and the flasks, during moulding, may be located laterally by a pneumatic clamp and guide. If desired, longitudinal location may be ensured by hydraulic-ram feeding devices which may also be used for any part of the flasks' travel. If the pressure applied to the sand is over 100 lbs. per square inch, moulding bars, bottom boards or other sand supports are not required. The moulding ram may include an axial cylinder in which a weight is reciprocated to give a jarring effect while pressing.

Abstract: 526,365. Wireless systems; directive aerials. STANDARD TELEPHONES & CABLES, Ltd. March 14, 1939, No. 8179. Convention date, March 15, 1938. [Class 40 (v)] A dipole aerial having an overall length onetenth that of the working wave, so that it is particularly suitable for portable sets, is directly coupled to a low-loss transmission-line, the combination being tuned to the operating frequency by a bridge-bar 4, whereby the efficiency of the system as a collector or radiator is made approximately equal to one of standard size. As shown, the capacitative impedance of the dipole 1, 2 is balanced by the inductance of the transmission-line 3, the latter being tuned by a shortcircuiting bar 4 to approximately a quarter wave-length. A receiver 7 is connected to a branch line 5, which is clamped to the main feeder at a point selected to match the impedances. A condenser 6; preferably of the splitstator type, is shunted across the main feed line to adjust the tuning of the system over a small range without moving the bar 4. For directional working two dipoles are coupled, in parallel, to the main feeder, through leads which are crossed in order to neutralize radiation in a direction at right-angles to the plane of the dipoles. The spacing of the two aerials is also preferably one-tenth the working wave-length.
