Abstract: 326,306. Gramophone Co., Ltd., and Morgan, R. B. Feb. 12, 1929. Vibrations, recording.-The light from an electric discharge tube used in recording mechanical or electrical oscillations is controlled or influenced magnetically. In the discharge tube described, a filamentary cathode 2 and a surrounding anode 3 ate enclosed in a glass or quartz envelope 1 containing mercury vapour, and a magnetic coil is arranged outside the envelope and coaxial with the filament. The magnet may be used only to concentrate the beam of light while it is modulated by fluctuating electrodepotentials, or, as shown in Fig. 3, the discharge may be maintained by a steady potential derived from a battery connected through a choke 5, the coil 4 then receiving the input oscillations and so modulating the discharge.

Abstract: 727,983. Dispensing pumps. VALBANIA, Ltd., and TANNER, T. H. Dec. 15, 1952 [Feb. 21, 1952], No. 4662/52. Class 102 (1). In apparatus for dispensing liquids, a container 2 is surrounded by a housing 1 fitted with a closure 4 carrying a dispensing pump. The closure is located on the housing by a projection 39 and secured by screws 43 in a flat surface 31 having a key-hole opening 34 and a screw hole 36 for attachment to a wall etc. The closure cannot be removed until the housing is removed from the wall etc. Slots in the housing enable the amount of liquid in the container 2 to be observed. A filling aperture in the closure is fitted with a plug attached to a chain 46 and ring 47 to prevent separation from the closure. The dispensing pump comprises a hollow member 6 having an outlet aperture 26 and attached to a cup 11, packing 13 being interposed between the two parts. A member 14 carries a spring-loaded valve 19 and is slidable in an opening in the member 11, the head 20 of a screw limiting outward movement. The member 6 is loaded by a spring 21 and its movement is restricted by a screw 22 engaging a groove 24. A double helice of wire 30 in the bore 25 produces lather when the apparatus dispenses soap. On the suction stroke, liquid enters through 'valve 19 and port 29 and on the delivery stroke is discharged through port 28 and aperture 26. Reference has been directed by the Comptroller to Specification 664,105, [Group XVIII].

Title: Improvements relating to apparatus for dyeing under pressure and methods of dyeing with such apparatus
IPC: D06B5/12
Filed: 1954-02-17
Abstract: Apparatus for dyeing or otherwise treating with liquid (shown in plans views in Fig. 2 and substantially in Fig. 3), comprices a hermetically sealed dyeing vat 1 and a hermetically sealed storage or expansion vat 2 togther with a centrifugal <PICT:0753676/IV(c)/1> <PICT:0753676/IV(c)/2> pump 3 having its input connected through a valve 8 to the storage vat 2 and its output connected through a conduit 9 to a distriber 5 (not visible in Fig. 2), there being also provided conduits leading from the distributer to the vat 1, to the vat 2 through the valve 12 and to the input of the pump 3 through the valve 15.  A further direct connection 18 provided with a valve 19 is made between the upper parts of the two vats for permitting the equilization of the pressures therein.  As indicated in Fig. 3 the distributer 5 comprises an internal tube 23, which is rotatable about the axis of the conduit 9, so permitting connection to be made between the conduit 9 and any one of the conduits 22, 221 and 10 the position of the tube 23 being controlled by the hand wheel 17, Fig. 2.  With the apparatus arranged as indicated in Fig. 3 the treatment liquid is circulated continuously between the vats 1 and 2.  The direction in which the liquid passes through the vat 2 may be reversed by rotating tube 23 to bring it into communication with conduit 22.  By changing over each of the valves 8, 12 and 15 liquid may be circulated through the vat 1 without passing through the vat 2, while by rotating the tube 23 to put it into communication with the conduit 10 and by suitably engaging the valves 8, 12 and 15, the liquid in the vat 1 may be wholly transferred to the vat 2.  An auxiliary 1 and 6 permits ingredients to be added to the expansion vat 2 while the latter is sealed

Title: Improvements relating to generators of electric oscillations having saw-tooth waveform
Inventor: SCOLES GRAHAM JOHN
IPC: H03K4/20
Filed: 1949-02-22
Abstract: 665,132. Saw-tooth generating circuits. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 13, 1950 [Feb. 22, 1949], No. 4817/49. Class 40 (vi). In a circuit in which a saw-tooth wave, comprising a capacitor which is charged through a valve made conductive or non-conductive by varying the grid potential, the limits of the saw-tooth wave are determined by the limits of the grid potential variations, which are independently adjustable. During the long flank of the saw-tooth wave a capacitor 1 discharges through a resistor 13 or through an equivalent pentode or saturated diode. The discharge continues until the voltage across capacitor 1 is insufficient to maintain valve 2 non-conductive and current then flows through a resistor 3, causing valve 10 to be cutoff. The anode voltage of valve 10 rises and the grid voltage of valve 2 accordingly rises to a value determined by a diode 7 and the potentiometer 6. Capacitor 1 therefore charges rapidly through valve 2 until the cathode voltage rises above the grid voltage, when the anode current ceases and a positive potential is-applied to the grid of valve 10. This lowers the potential of the cathode of a diode 8 and since resistor 5 is of high value lowers its anode voltage and the grid voltage of valve 2 to the same value. Capacitor 1 again discharges slowly until the cathode voltage is below this grid voltage, the value of which may be adjusted by potentiometer 9. The input circuit of valve 10 is arranged to effect D.C. restoration and capacitor 11 may be replaced by a resistor.

Abstract: 1,132,784. Purifying aromatic or alicyclic dianhydrides. GELSENBERG BENZIN A.G. 4 Feb., 1966 [5 Feb., 1965], No. 4988/66. Heading C2C. Crude aromatic or alicyclic carboxylic dianhydrides are purified by extraction with an aromatic hydrocarbon capable of forming an adduct with the dianhydride, at or below the boiling point of the hydrocarbon, at normal pressure or at an elevated pressure, and then a hot filtration is effected, from the filtrate of which an adduct of the aromatic dianhydride is crystallized out upon cooling and isolated by filtration whereupon the adduct is converted into the dianhydride by removal of the extraoting agent. Typical aromatic dianhydrides are pyromellitic dianhydride, naphthalene-tetracarboxylic dianhydrides, diphenyl-tetracarboxylic dianhydrides, benzophenone-tetracarboxylic dianhydrides, cyclopentane-tetracarboxylic dianhydrides and bis-(dicarboxyphenyl)- sulphone dianhydrides. Suitable extracting agents are benzene, toluene, o-xylene, p-xylene or higher alkylated aromatic hydrocarbons or mixtures thereof. The extracting agent may be removed by heating. The pyromellitic dianhydride may be derived from oxidation of a 1,2,4,5-tetra-alkyl benzene.

Abstract: 961,298. Manometers. COUNCIL FOR SCIENTIFIC INDUSTRIAL RESEARCH. Feb. 7, 1961 [Feb. 12, 1960], No. 5044/60. Heading G1L. A manometer which comprises a closed limb AB and an open limb F, D with bulbs P1, P2 of substantially equal volume provided respectively at the top of the closed limb and between the two limbs, contains, sufficient mercury or the like to extend from E to F at zero reading. If air manages to seep into the Torricellian vacuum above the mercury in limb AB its effect on the levels in limbs EB, FD is reduced by bulb P, since the pressure exerted by this air is inversely proportional to the volume it occupies. The bottom U portion of the manometer may be of constricted bore to damp the effects of sudden pressure changes.
