Patent GB-452215-A (GB)
Title: The manufacture of high molecular organic sulphur compounds
IPC: C08G75/16
Filed: 1935-02-18
Abstract: High molecular sulphur-containing products are obtained by reaction between water soluble polysulphides and polyhalogenated compounds having the halogens attached to carbon atoms and containing the group >C=O, the polysulphides being employed in an amount sufficient to combine with the halogen.  The substances produced are of plastic to elastic properties and may be vulcanized.  Examples of polyhalogenated substances are esters of polyhydric alcohols (e.g. glycerine) with halogenated fatty acids (e.g. mono- or di-chloracetic or propionic acid), esters of halogenated alcohols with polybasic acids, carbonic acid esters of halogenated alcohols, esters of halogenated alcohols with halogenated acids, polyhalognated ketones, amides of halogenated p  acids and polyamines, urea derivatives containing halogen - alkyl groups attached to nitrogen, amides of halogenated acids and halogen - alkyl amines or amides of polycarboxylic acids and halogenated amines.  When the reaction is carried out in the presence of water emulsifying agents may be added such as sodium di-isobutyl sulphonate, condensation products of fatty acids with aliphatic amino-alkyl-sulphonic acids and condensation products of oleic acid chloride with amino-carboxylic acids such as hydrolyzed albumen.  Surface-active solid dispersing agents may also be employed to assist the reaction, e.g. freshly precipitated barium sulphate, magnesium hydroxide or aluminium silicate.  Under such conditions the condensation products are obtained in the form of a latex-like emulsion which may be worked up in a manner similar to that used for natural rubber.  According to examples: (1) glycerine tris-monochloracetate in admixture with alcohol is treated with concentrated aqueous sodium trisulphide; (2) glycerine tris - monochlor - acetate in admixture with alcohol is treated with alcoholic sodium polysulphide; (3) glycol dichloracetic acid diester in alcoholic solution is treated with a 35 per cent aqueous solution of sodium trisulphide; (4) sorbitol tetra-monochloracetate in alcoholic solution is treated with alcoholic sodium polysulphide; symmetrical dichloracetone is treated with aqueous sodium polysulphide; (6) monochloracetic acid beta-chlorethyl ester is treated with an aqueous solution containing crystallized sodium sulphide and sulphur; (7, 8, 9) monochloracetic acid betachlorethylamide, dichlordiacetyl - ethylene - diamine, carbonic acid dichlorodiethyl ester respectively are treated with aqueous solutions of sodium sulphide in which sulphur has been dissolved.

Title: Transducer
Inventor: FIELDEN JOHN ERNEST
IPC: G01F1/36
Filed: 1958-02-21
Abstract: 847,863. Electric measuring systems. FIELDEN ELECTRONICS Ltd. Feb. 16, 1959 [Feb. 21, 1958], No. 5672/58. Class 40 (1). [Also in Group XXXVI] In means for producing an output current substantially proportional to the square root of an input, which may be a displacement or a voltage, the output current, which is derived from a circuit comprising an oscillator whose amplitude of oscillation is determined by the value of a reactance responsive to the input, energizes means to produce a current or voltage which is proportional to the square of the output current and which operates to maintain the value of the reactance substantially constant. In a flowmeter, Fig. 1, the plates 4, 6 of a capacitor are mounted on coaxially-pivoted levers 2, 5, respectively, the angular position of the lever 2 being determined by the differential pressure across a Venturi &C in a flow-pipe 1. The capacitance of capacitor 4, 6 determines the amplitude of the output of an oscillatory circuit 8 which is fed to the heater 9 of a thermojunction 10 whose output, which is proportional to the square of the heater current, is fed to a moving coil movement 7 to cause plate 6 to follow plate 4 until the capacitance is restored substantially to its former value, when meter 18 gives a linear indication of the rate of flow. In Fig. 2, plate 4 is fixed and the moving-coil 7 is fed with the difference between an input potential, which may be representative of a pressure differential, impressed at terminals 16, 17, and the output potential of the thermojunction 10. The moving coil arrangement may be replaced by a pivoted lever displaceable by an electromagnet, and a variable inductor may be used in place of the variable capacitor.

The dimmer control potentiometers of a stage lighting system may be selectively connected, individually or in groups, to a master potentiometer and then transferred to a second master potentiometer leaving the first available for connection to further dimmer potentiometers. Fig. 1 shows the basic circuit arrangement which uses bi-stable relays 8, 8<SP>1</SP> and is so arranged that, by suitably operating switches 6, 6<SP>1</SP>, 9, either or both of the dimmer potentiometers 1, 3 can be connected to the master potentiometer 5 and then transferred to the second master potentiometer 7. The selector switches 6, 6<SP>1</SP> may be operated manually or electrically from a memory store. After selection, the individual dimmer potentiometers may be adjusted as desired, the master potentiometer is moved from the " full-off " to the " full-on " position (at the required rate) and the potentiometers are then transferred to the second master potentiometer. Some or all of the transferred potentiometers may be reconnected to the master for fading-in or out. Alternatively this may be done by using the second master. Provision is made for the adjustment of one or a number of selected dimmer potentiometers without disturbing the existing selection, for transferring a single "selected" potentiometer from a number of selected potentiometers, or for " blacking out " those light channels under the control of the first or second master potentiometer. Various selections may be connected to a memory store for subsequent reproduction. The panel arrangement, circuit diagram and operation of a control system embodying the above features is described, Figs. 2, 3 and 4 (not shown).

Moulding material is thus forced into the mould cavities to take up shrinkage as the material solidifies. The accumulator chamber 68 contains a ram 67 operated by a single acting hydraulic ram 78. When fluid material is being fed by the feed means 75 to the accumulator chamber 68 the ram 67 is moved upwardly against the resistance offered by an hydraulic restrictor 88. A nozzle valve 70 is opened and closed when the nozzle is engaged with and disengaged from the moulds. The mould cavities are provided by a plurality of centrally apertured plate-like elements 35 interleaved with a plurality of ring-like elements 36, and housed in a guide 23. The elements 35, 36 have passages 51, 52 respectively therein to receive heating and cooling fluid. The elements 35, 36 defining cavities 38-14 are water cooled and the elements defining cavities 45, 46 are heated by warm air. The mould guide 23 is guided for vertical movement by means of slides 11a and mounted on a table 14 which can be raised and lowered by means of an hydraulic jack 20 and toggle arms 15. Removal of a filled mould from the lower end of the series is effected by an hydraulic jack 55 which pushes the mould on to a platform 63 having an opening 64 through which the moulded article can drop. A pair of pneumatic rams (62), Fig. 2, (not shown), are operated to lift the stack of mould elements slightly as soon as the mould being removed has moved clear of these rams. An insertion platform 65 having a removable heating jacket 66 may be connected to the platform 63 by an endless belt or the like (not shown). Fluid pressure admitted to a cavity 33 acts on a piston 27 which presses the mould elements 35, 36 together and against the table 14. Modifications.-The feed of material to the accumulator chamber may be shut off during the provision of an empty mould cavity at the input end of the series. Two accumulator chambers and two series of mould cavities fed from a single feed means may be provided, material being fed into one chamber while the other is disconnected from its series.
