Patent GB-406855-A (GB)
Title: Process for the production of monobasic aluminium sulphite
IPC: C01F7/72
Filed: 1933-01-20
Abstract: Monobasic aluminium sulphite is obtained by heating aluminium sulphite solutions under conditions wholly or partially maintaining the sulphur dioxide concentration, at least two molecules of sulphur dioxide per molecule of alumina being maintained.  The ratio of silica, if present, to alumina in the solution must not exceed 2 : 100.  The concentration of sulphur dioxide may be maintained by heating the solution under pressure, for example in a lead-lined autoclave provided with an agitator, at from 70 to 150 DEG  C.  The solution may be heated at temperatures below 90 DEG  C. in open vessels.  It may originally contain say from p  33 to 170 grms Al2O3 per litre.  If, when impure aluminium sulphite solutions are employed, the deposited salt contains iron, the salt is dissolved in aqueous sulphurous acid, and redeposited while maintaining the sulphur dioxide concentration.  Aluminium sulphite solutions containing silica and iron may be heated first in the usual manner to expel sulphur dioxide and produce a basic aluminium sulphite mixture relatively poor in sulphur dioxide, which is then dissolved in preferably concentrated aqueous sulphurous acid; monobasic aluminium sulphite is deposited from the resulting solution by heating under the conditions maintaining the sulphur dioxide concentration detailed above.  Residual mother liquors may be employed for decomposing aluminous compounds.  The density of the monobasic aluminium sulphite, and that of the alumina obtained by calcining the same, increases with increasing deposition temperature.

Abstract: 657,258. Wrapping nested receptacles. STEVENS, A. H. (Sutherland Paper Co.). Jan. 26, 1949, No. 2131. [Class 94(i)] In a method of wrapping a group of nested cups 2 to form the package shown in Fig. 2, a web or strip of heat-sealable, transparent wrapping material 12 with a superposed label strip 14 is advanced step-by-step through a channel 16, 17 and the groups of cups deposited thereon at intervals with their tops facing rearwardly leaving substantial portions 18 of wrapping strip between adjacent groups. The edges 7 of the strip are then overlapped and heat-sealed by an element 20 over at least a portion of the length of the package, and the portions 18 puckered and collapsed by elements 21, 22 prior to heatsealing by elements 23. 24 which form spaced seals 8, 9. The strip is simultaneously severed between the seals by a knife 25 to form individual packages. The movement of a package beyond the sealing and severing point is restrained or frictionally retarded, e.g. by means 26 and a holder 28, so that the following package is advanced into nested relationship therewith to tuck the sealed ends 10 and 11 of the wrapper into the recessed end of the bottom cup of the group and the top cup of the group respectively. A stack of nested packages is thus formed which is suitable for storage or packing in a shipping container.

Title: An Improved Process for the Manufacture of Matches.
Inventor: BEST THOMAS THOMPSON
IPC: C06F3/00
Filed: 1916-02-15
Abstract: 104,015. Best, T. T. Feb. 15, 1916. Matches.-The igniting-compound used for match heads contains a proportion of sodium chlorate from which the hygroscopic impurities have been removed. The remaining substances may be potassium chlorate, gum, quartz or glass powder, antimony sulphide, sulphur, phosphorus and its compounds, zinc oxide, calcium sulphate, and paraffin wax. The ingredients are made into a paste with water and applied to the match sticks in the ordinary way. The ends of the match splints may be impregnated with hot paraffin wax before being cooled, and the splints may be the usual wood strips or strips of card, or taper. The sodium chlorate is preferably made by treating a warm solution of sodium carbonate with chlorine and concentrating the solution till it contains 1100 grm. of scdium chlorate per litre. The solution is kept in steam-heated vessels until the sodium chloride ceases to crystallise out. The solution is then filtered and diluted with water to a strength of 825 grm. of sodium chlorate per litre. Any remaining sodium chloride is thus retained in solution, while pure sodium chlorate crystallizes out.

[Also in Division H3] The temperature coefficient of the simulated Zener diode of the main Specification 1,230,879 which comprises at least three transistor structures formed as an integrated circuit and having a common collector region, the emitter junctions of the transistors being connected in series so that at least one is reverse biased to form a Zener diode and the remainder are forward biased, is reduced by incorporating a further transistor in the structure sharing the common collector region and having its emitter junction forward biased, and its base region biased by a potential divider comprising two resistors connected to the transistor collector and emitter, the value of at least one of the resistors being adjustable during manufacture. The residual temperature coefficient of the structure is measured and the values of the resistor are selected to provide compensation. In a first embodiment, Fig. 3 (not shown), the resistors are formed as diffused regions, the collector-base arm being formed in four sections in series the connections between which are provided with conductive connecting pads overlying an insulating layer on the surface of the wafer. One pair of adjacent pads may be bridged by a deposited track to select the desired resistance value. In a second embodiment, Fig. 4 (not shown), the resistors are formed as deposited tracks the arms of the potential divider being connected to the collector and emitter of the transistor and each comprising a plurality of sections of varying resistance having connection pads located on either side of a conducting strip connected to the base region of the transistor. A single strip of conductive material deposited across the conductive strip interconnects the connection pads of the desired resistor tapping parts and the base of the transistor. In a further embodiment, Fig. 5 (not shown), the resistors are in the form of deposited tracks, the emitter-base resistor being fixed in value and the collector-base resistor comprising a plurality of sections of different resistances joined by conductive pads adjacent ones of which may be connected together by a deposited connection to short out the relevant resistor section. The deposited selective connections may be connected together by a deposited connection to short out the relevant resistor section. The deposited selective connections may be replaced by wires bonded to the pads. In a further embodiment, Fig. 6 (not shown), the collector-base resistor comprises a broad diffused region or deposited area the resistance of which may be increased to the desired value by removing its lateral edge by sandblasting or etching.

Abstract: 304,789. Wrangell, M. de. Jan. 27, 1928, [Convention date]. Addition to 278,386. Driving.-The alternative spring and electric motor drive of the parent Specification is controlled by the screwing on of the winding key or .handle preparatory to winding the spring, such action moving a slide to release the clockwork train and to open the motor circuit. The spring and the electric motor drive the turntable through free wheels, and the governor is driven from the turntable shaft so as to be effective! with either drive. When the key 14 is screwed on the winding spindle 15 for the spring motor it presses back a slide 18 against the action of a spring 19 so that a projection 27 on the slide disengages a ratchet wheel 28 on a shaft a driven from the spring motor 2 and driving the turntable spindle 1 through a free wheel 6. This movement of the slide also rocks a lever to open a switch in the electric motor circuit, such motor being driven through belt and pulley 3 and a worm 9 and wormwheel 10 and driving the spindle 1 through a free wheel. On unscrewing the winding key 14 the spring 19 returns the slide 18 to again lock the ratchet wheel 28 so as to arrest the spring drive, and also rocks the switch controlling arm so that the circuit of the electric motor is closed. The governor 13 is driven by wheel 11 and worm 12 from the turntable spindle 1. Specification 282,014 is referred to.
