Title: Improvements in storage batteries and process of producing same
IPC: H01M4/20
Filed: 1925-05-20
Abstract: 257,019. Downer, G. F. May 20, 1925. Electrodes.-Plates for storage batteries are made by pasting the grids with a substantially inactive paste of lead oxide and water and afterwards sulphating by soaking in a solution of sulphuric acid, loosening of the paste upon immersion being avoided by having surface pores full of water at the instant of immersion. The paste may also include some porosity producing agent such as magnesium sulphate or porous organic material, and an inactive solution may be used in place of pure water. The same materials are used for both plates, and the lead oxide may contain from 40 to 75 per cent of litharge, the balance being red. lead. The pores may be produced by passing the pasted grids between rollers covered with woven wire cloth or canvas. The plates may be dipped in or sprayed with water before being soaked in the acid solution. They are then assembled in battery jars containing distilled water or very weak acid and a charging current is passed through the cells; when charging is complete, the acid in the cells approximates to the normal strength.

Abstract: 1294742 Spinning pack containing a filter TORAY INDUSTRIES Inc 19 March 1970 [22 March 1969 23 May 1969 4 Feb 1970] 13244/70 Heading B5B [Also in Division B1] As shown in Fig. 1A, a melt spinning pack for fibre-forming polymeric materials comprises a housing 1 containing a spinning head 2 having extrusion orifices 3 and supported on a shoulder 4, a packing ring 5 being provided between the shoulder and the spinneret plate. A filter element support plate 6 is supported on the spinning head 2 by a packing-ring 7. The plate 6 has a number of ducts 9 communicating with the orifices 3 through the distributing space 8. A number of substantially vertical porous hollow filter candles 10 are detachably mounted in the support plate 6. The peripheral wall 11 of each filter candle is porous and the upper end of each candle is closed in a liquid-tight manner by an impervious cap 13 and a washer 15. The open lower end 16 of each candle 10 communicates with at least one aperture 9 in the support plate 6. The joint between the lower end of the wall of each candle 10 and a corresponding annular recess in the plate 6 is rendered liquidtight by a washer 17. The top of the housing 1 is closed by a closure member 18 having an inlet passage 19. The joint mating surfaces of the housing 1 and the plate 18 are sealed by a gasket 20. The filter candles 10 may be detached from the support plate 6 for cleaning. The caps 14 sealing the upper ends 13 of the filter candles 10 may or may not be detachable. In the apparatus of Fig. 2, a plate 26 has apertures 25 through which the melt can flow from inlet passage 19 to the space 21 surrounding the filter candles and is provided on its lower surface with studs which contact the caps 14 of the filter candles. The plate is supported on the upper edge of a hollow cylinder forming part of the filter candle support plate 6 and surrounding the assembly of filter candles in such a manner that it can be urged downwards and thus press the caps 14 into tight engagement with the upper ends of the filter candles 10. Fig. 3A (not shown) illustrates a modification of this apparatus with provision for individual adjustment of the setting of each filter candle cap, so preventing the candles leaning owing to uneven distribution of melt in the pack. In the apparatus of Fig. 4 the member 6 carrying the filter candles 10 is a cylindrical block which is a close fit in the spinning pack housing and which is provided with a number of vertical cylindrical recesses 40 each accommodating a filter candle and each having a diameter slightly larger than the filter candle so that the spinning melt can flow into the spaces 41 between the recesses and the filter candles and from thence through the walls of the filter candles. This construction has the advantage that the volume of melt in the spinning pack is reduced and the formation of zones between the filter candles in which the melt is stagnant and tends to decompose is prevented or minimized.

Abstract: 132,562. Western Electric Co., (Western Electric Co.). June 24, 1918. Wireless signalling; multiplex wireless signalling.-Wireless signalling is effected by a highfrequency carrier wave modulated by a wave of intermediate and inaudible frequency, which is itself modulated in accordance with the signal to be sent. Multiplex working is obtained by employing several non-interfering intermediate frequences, and, if desired, several carrier frequencies. The transmitting-apparatus shown in Fig. 1 comprises a high-frequency generator 1 with a frequency of, say, 1,000,000, coupled to a circuit 2. A number of generators 3, 3<1>, 3<11>, &c., of frequencies, say, 40,000, 30,000, 20,000, are connected through thermionic modulators 4 to tuned circuits 6 coupled to the circuit 2. The oscillations generated by the sources 3, 3<1>, &c. are modulated by microphones 5 or other source of audible-frequency signal currents. The modulated oscillations in the circuits 6 are combined with the carrier waves in the modulator 7, and are amplified by the relay 9 and transferred to the aerial 10. At the receiving-station, Fig. 2, the waves are received in a circuit 13 tuned to the carrier frequency, and are rectified to currents of the intermediate frequencies by the detector 14. These currents are separated bv the circuits 15, 15<1>, &c. tuned to the various intermediate frequencies, and are transferred to other tuned circuits 16, 16<1>, &c., which are connected across the grid and filament of rectifiers 17. Telephone receivers 18 are placed in the plate-filament circuits of the detectors

Patent GB-133374-A (GB)
IPC: C12P7/20
Abstract: 133,374. Eoff, J. R. July 21, 1917, [Convention date]. Glycerine, obtaining.-Glycerine is produced by fermenting sugars with veast in the presence of an alkali or alkaline salt, the proportion of alkali &c. being just below that which inhibits the activity of the yeast. Acetic acid, alcohol, and acetone are obtained as by-products. Any yeast capable of acclimatization in an alkaline medium is used. The yeast is first cultivated in sterile grape juice, and when in vigorous growth is added to a medium consisting of a wort made from malt sprouts, dextrose, and a yeast food such as Pasteur's solution, or a mixture containing ammonium nitrate, potassium phosphate, ammonium phosphate, magnesium sulphate, and traces of zinc and iron salts. When fermentation is active, sodium or potassium carbonate, phosphate, or hydroxide is added in successive doses up to the limit previously indicated. The " starter " so obtained, when fermenting vigorously, is added to a larger quantity of the medium, and alkali is added as before, the product being used for the manufacturing operation. The material treated for the production of glycerine may be either a solution of dextrose to which a wort obtained from malt sprouts is added, or " black strap " or other molasses, or purified and neutralized waste, sulphite liquor. The temperature is maintained at 27-50‹ C. preferably 37‹ C., during the fermentation. In treating molasses, the initial stage of the fermentation is effected while the molasses is slightly acid, in order that the sucrose may be inverted by the invertase of the yeast. Afterwards, successive doses of alkali are added in the ordinary manner. Reference has been directed by the Comptroller to Specifications 138,099, 138,328, 138,329, 138,330 and 138,331.

Filed: 1965-04-01
Abstract: 1,076,731. Measuring alignment of holes in components. SOCIETE FRANCAISE DES COUSSINETS MINCES. April 1, 1965 [April 10, 1964], No. 13893/65. Heading G1M. In a method for ascertaining the presence and alignment of holes in a component such as a bearing, each component is placed on a block 1 pierced by passages aligned with the expected hole positions, and a high or negative pressure is applied to the passages, any variation in pressure being detected as a measure of the presence or alignment of the holes. As shown in Fig. 1, the apparatus includes the block 1, formed with a seat 2 for supporting the bearing and a flange 5 displaceable by a piston 7 operated under air pressure controlled by a distributor 8. The block 2 is supplied with air pressure through lines 8a, 9 controlled by a distributor 10. The apparatus is further provided with two air pressure circuits, one, a high pressure circuit fed in at 12 controlled by manually operated valves 13, 14 and the other, a low pressure circuit leading from a reduction valve 17, through the distributor 10 to passages 8a, 9. In case the bearing 3 is inserted into the seat 2 and valves 13, 14 are opened to move the flange 5 into abutment with the bearing, thus moving the bearing to a position where the passages 8a, 9 should register with the bearing holes. If holes are present the pressure gauge 23 remains inactive, but if they are absent a contact 25 is operated actuating a valve 24 to cancel the feed of compressed air to distributor 8. Consequently the distributor remains in the operative position preventing depression of levers 15, 16 and non- operation of an ejector 28.
