Abstract: Dry cast sheets or films of a water-soluble polyvinyl alcohol, including the products of incomplete saponification of polyvinyl esters, and polyvinyl alcohols containing acetal groups, capable of being easily stripped from the casting wheel in an undeformed or unmarred condition, are produced by incorporating into the casting solution a stripping agent of the following class: <FORM:0566144/IV/1> A water-soluble ester of a sulphonium acid salt of an aliphatic dibasic acid in which X is a bivalent radical of not more than 8 carbon atoms, Y and Z are alike or different, and are alkyl and aryl radicals of not more than 18 carbon atoms, and M is an alkali metal or ammonium radical.  The sum of the carbon atoms in the radicals X, Y and Z is not less than 11 and not greater than 32. The central residue may be that of malonic, succinic, glutanic, adipic, subaric, azelaic and sebacic acids.  The stripping agent may be used alone or in combination with others of the type, or with other known stripping agents, e.g. higher straight chain fatty alcohol alkali metal sulphates and alkyl naphthalene sodium sulphonates.  Softening or plasticising agents may be added, e.g. glycol, hexaethylene glycol, glycerol, formamide acetamide, ethanol formamide, ethanol acetamide.  Examples are given employing the di-octyl, the di-hexyl and the di-amyl ester of the sodium salt of sulphosuccinic acid, as the stripping agents.

Title: Method of controlling atmosphere in a drip feed gas carburizing furnace
IPC: C23C8/20
Filed: 1970-01-23
Abstract: 1,247,642. Automatic concentration control. TOYO KINZOKU KAGAKU CO. Ltd. Jan.23, 1970 [Jan.23, 1969], No.3345/70. Heading G3R. [Also in Division G1] Variation of the concentration of one of the gases present in a drip feed carburizing furnace is detected and utilized to restore the desired concentration by automatic control of the relative proportions of two different organic liquids being dripped. In Fig.6, gases from a carburizing furnace 10 are exhausted at 12, passed through filters 13, 14, cooled at 15 and mixed at 16 with nitrogen from a source 17 purged at 18. The gas mixture passes through a further filter 19 to an infrared carbon dioxide detector 20 from which it is extracted by a pump 22 and exhausted at 23. In the carbon dioxide detector the gas passes through a test cell 31, Fig.7, and infrared radiation from a source 36 is alternately passed, by virtue of a rotary shutter 42, through test cell 31 and through a standard cell 34 absorbing less radiation, so that each influences a device 39 in which the radiation varies gas pressure to move a foil varying electrical capacity. This variation controls, through an amplifier 46, synchronizer 47 and a further amplifier 24, a reversible servomotor 48 which adjusts an optical iris 49 until equal radiation is received through the two paths. Motor 48 also operates a potentiometer 51 and develops at 52 a temperature-compensated signal corresponding to the carbon dioxide content. This signal is applied through a controller 26, Fig. 6, and an amplifier 30 to operate a differential valve 11 in which a flapper is moved relative to opposed nozzles so that the ratio of the supplies of two different carburizing liquids A and B to furnace 10 is varied to correct variations of carbon dioxide content while maintaining to total supply of carburizing liquid constant.

Title: Improved tea preparation
IPC: A23F3/42
Filed: 1956-02-02
Abstract: A tea preparation is produced by withering green tea leaves, boiling them with water, separating the resultant liquid from the leaves and extracting it with ether or other solvent, concentrating and filtering the aqueous extract, evaporating it to dryness and powdering the residue which is mixed with the product obtained by successively washing the ether extract with water and drying and evaporating it.  Preferably the leaves are withered by exposing them to open air for about 3 1/2 hours and then they are boiled with water in a covered vessel for about 20 minutes, 4 to 5 1/2 and preferably 4.8 pints of water being allowed per pound of tea.  The leaves may be pounded in a mortar before extraction.  The liquid is poured off the leaves and when cool is extracted with ether.  The aqueous extract is evaporated to a small volume, filtered and evaporated to dryness on a steam bath and powdered.  The ether extract is washed with water, dried with anhydrous sodium sulphate and evaporated at room temperature by blowing with air.  The extracts are then mixed. According to the Provisional Specification, green tea is crushed by passing it between rollers and then fermented, fermentation being assisted by sugar or the like, after which the liquor is expressed from the leaf, evaporated and dried.

Title: Container bottom valve
IPC: F16K1/00
Filed: 1976-01-29
Abstract: 1512142 Bitumen tanks GUSTAV F GERDTS KG 29 Jan 1976 [28 Feb 1975] 03448/76 Addition to 1484743 Heading E1G [Also in Division F2] The bottom valve of the parent Specification is modified in that the extension or sleeve between the upper and lower closure members is fixed and has lateral passages 6 through its bottom end, and the lower closure member is in the form of a tubular slider 10 arranged concentrically in or on the sleeve. The slider 10 is subjected to the forces of a closing spring 15, an opening spring 16 and a main closing spring 25. Upward movement of actuating rod 19 opens the closure member 9 as shown in the right-hand half of the drawing, whereupon molten material flows through the sleeve to the outlet 4, thereby heating and melting the solidified material at the bottom of the container 1. Moreover, the upward movement produces a net opening force exerted on the slider 10 by the springs. Thus as soon as the solidified material melts the slider is opened and allows the material to flow to the outlet via the passages 6. Bellows 11, 22 and air trapped in annular chambers 13, 24 prevent the material from reaching the cooperating sliding surfaces 12, 23 of the valve.

Title: An electric current-rectifying apparatus
IPC: H01L25/03
Filed: 1960-02-01
Abstract: 911,134. PN-junction rectifier assemblies. SIEMENS-SCHUCKERTWERKE A.G. Feb. 1, 1960 [Jan. 31, 1959], No. 3567/60. Class 37. In an assembly comprising a plurality of parallel connected PN junction rectifiers, the rectifiers are mounted on the outside of the cylindrical electrically-conductive rim of a hollow-hubbed spoked wheel. One electrode of each rectifier is in electrical contact with the rim and the other electrodes of the rectifiers are connected together. To facilitate cooling the inner surface of the run is finned. Several wheel assemblies may be clamped together on a central bolt which may also be used as a bus-bar. In one embodiment, Fig. 3, three assemblies of the above type with hubs of different internal diameters are superposed and aircooled by fan 13. The wheels 4 which have annular recesses are insulated from each other by pairs of stepped washers 9 which mate with the recesses to locate the wheels coaxially. Alternatively the wheels may be located by dowels and corresponding bores. The rectifiers 2, the housings of which form the electrode, are individually connected in series with cartridge fuses 3 which may, if desired, be disposed obliquely or transversely with respect to the wheel axes to allow the axial dimension of the wheels to be reduced. Each rectifier is mounted in a housing the base portion of which is attached to a nut screwed into a tapped hole in the wheel rim. A central bus-bar 11 fits into the hub of the lowest wheel which is linked to the other wheels by bridging members 18. The other side of each fused rectifier is connected by a radial conductor 12 to one of three coaxial tubular bus-bars 10 insulated from the wheel hubs. Such connection enables the assembly to be used in the circuit of Fig. 3a. In an otherwise similar arrangement (Fig. 5), the wheels are insulated from each other but electrically connected to respective coaxial bus-bars 10, the other sides of the individual fused devices being connected by parallel rods 17 connected to tubular bus-bar 11 by radial conductors 12. In a further arrangement (Fig. 6), comprising four wheel assemblies, the parallel connected rectifier assemblies on the lower two wheels are connected in series and have one pole in common with the series connected assemblies on the upper two wheels. In yet another arrangement (Fig. 7), the parallel rectifier assemblies on all the wheels are connected in series with a centre tap connection to bus-bar 10 via radial conductors 12. Any of the above arrangements may be modified by replacing the chimney 14 by an axially rotatable closed casing, preferably wholly of or with windows of transparent plastic material. The fan in this case blows air through the spokes of the wheels and then in the reverse direction past their rims, which may be hollow and filled with liquid coolant.
