Title: Improvements in or relating to control devices for liquid flow
IPC: F16K24/06
Filed: 1931-01-05
Abstract: 370,403. Air venting valves. WHYATT, C. E., 74, Halsbury Road, East Northolt, Middlesex, and ELECTROLUX, Ltd., 153, Regent Street, London. Jan. 5, 1931, No. 382. [Class 135.] An inlet valve which, by admitting air to a chamber inserted in a liquid supply line, prevents the return flow of liquid therethrough, is always maintained out of contact with the liquid. In a preferred form, a liquid inlet 11 and a liquid outlet 12 are in alignment to facilitate insertion in a pipe' line. The outlet 12 communicates with an opening 15 at the bottom of the chamber 10 by a passage provided by a depending flange 14 which also serves to maintain a liquid seal for the air trapped in the pocket 22, provided by the shrouding member 20, after flow has commenced. The shrouding member 20 also prevents liquid from the inlet reaching the valve 16. The latter which is located above the chamber 10 is loaded by a spring 17, the compression of which may be regulated. The outlet 12 is adapted to be connected to some apparatus at its own or a lower level. In the absence of a liquid head on the outlet side, the valve 16 admits air to prevent return flow when the pressure at the inlet falls below a predetermined subatmospheric pressure. Apertures 18 in the spring housing are covered by a gauze 19 which prevents the access of solid matter to the valve. To allow of the removal of solid impurities collecting in the bottom of the chamber 10, a screwed plug 21 is provided.

In a method of making a photographic silver halide emulsion wherein an aqueous solution of a silver salt and an aqueous halide solution are simultaneously added to an aqueous medium which contains, or has added to it during the above addition, a water-soluble thiocyanate, the concentrations of the water-soluble salts, their times of addition and the temperature of the aqueous medium are controlled so that a coarse grained emulsion having a mean grain projective area between 0. 6 and 2. 5 Á<SP>2</SP> is produced. The time of addition may be from 20-60 mins., and the concentration of the thiocyanate in the aqueous medium may be from 0. 75-7. 5 mole % of the total silver halide formed, or, if added with the halide solution, up to 20 mole % of the total silver halide formed. The aqueous medium is preferably maintained at 65-85C. In the examples, a solution of 39g. of silver nitrate in 200 ml. of water and a solution of 28. 6 g (or 29.1 g) of potassium bromide in 200 ml. of water are simultaneously added to 113 (or 115) ml of water containing gelatine, sulphuric acid and a small amount of KBr or NaCI at 72C. over a period of 40 minutes. 3g. of KCNS are present in the aqueous medium or 6 g. in the KBr solution. A water-soluble lead salt also may be added to the aqueous medium, for example by inclusion in the silver nitrate solution. A halogen acceptor such as thiosalicylic acid may be added to the emulsions after the precipitation.

Abstract: 1,152,008. Methanating a combustible gas. 22 Feb., 1967 [5 Jan., 1966], No. 553/66. Heading C5E. A reactant gas containing H 2 , CH 4 , carbon oxides and steam is methanated over a suitable catalyst in the form of a fluidized bed located in a reaction zone, the zone being in heatexchange relationship through a heat-conducting wall with a cooling zone through which a fluid is passed. The fluid may be a mixture of diphenyl and diphenyl oxide, air, steam, or 1.p.d., or a mixture of steam and 1.p.d. which is to be the feed to a catalytic gasification stage which provides the gas to be methanated. In a specific embodiment, see Fig. 1 (not shown), the cooling zone is a series of interconnected vertical tubes, with header rings top and bottom, which depend into the bed. The reactant gas is the fluidizing gas and is delivered to the bottom of the bed through a distributer which may be constructed as described in Specification 1,036,890. Cooling fluid leaving the zone may pass in heat-exchange relationship with gases leaving the gasification stage to cool them prior to their entry into the reaction zone.

The disc may be held on a punch 1 by rod 2 with a centring pin 3 and is drawn by a die 9 moved down by a sleeve 18 until it is stopped, while still in contact with the lower edge of the cylinder 20, by engaging a bed 21. Further movement of the sleeve 18 moves an internally coned sleeve 13 down, against the action of a spring 14, thus pressing wedge fingers 10, provided with number type faces 12, radially inwards to form intaglio numbering. If raised numbering is desired the fingers 10 have intaglio numbering and levers with raised type faces are arranged in the punch 1 and adapted to be pressed outwards by the descending die 9. In a modification the radially movable dies 22, Fig. 3, are operated by an annulus 25 which engages the dies by a spiral thread 24 and is rotated, through a distance determined by an adjustable stop by a hand or machine-operated lever 27. Instead of a thread the annulus may have rollers to engage cam slots in the dies.

Filed: 1943-01-18
Abstract: <PICT:0568670/IV/1> The gaseous reaction products obtained by treating acetonitrile with chlorine are scrubbed with water, and the resulting condensate and aqueous layer allowed to separate.  The scrubbing water may be used to scrub further quantities of gaseous products and the process made continuous.  In the Figure, gaseous products from a reaction chamber 1, packed with active charcoal are washed in a scrubber 3 after passing through a cooler 2, with water which circulates through the scrubber 3, settler 4, storage tank 5 and cooler 7.  The non-aqueous product pass to a still 8, the chlorinated acetonitrile leaving the latter at the bottom and the gases passing to a reflux condenser 10.  The condensate from the reflux condenser passes to a washing vessel 9 and the gases pass out of the system together with those from the scrubber 3.  Water is supplied to the vessel 9 from a reservoir 11.  Examples are given in which mono-, di-and tri-chloracetonitrile are produced, using a reaction chamber packed with charcoal and also an empty glass chamber.  Specification 567,289 is referred to.

Abstract: In the case of an optical pick-up device for reading a magneto-optical recording medium, depending on the direction of rotation of its polarisation plane, the light beam reflected by the recording medium is reflected onto a first photodetector or a second photodetector. The data signal is obtained from the difference between the photoelectric voltages of the two photodetectors. 
<??>With a novel recording medium on which data are stored by means of pits and in magnetic domains, in order to be able to read both types of data simultaneously, the data signal PS, which represents the data which are stored by means of the pits, is obtained from the sum signal of the two photoelectric voltages. The data signal MS, which represents the data contained in the magnetic domains, is obtained from the difference signal of the two photoelectric voltages. The data signal PS can also be obtained by the transilluminating method by means of a photodetector (24, 25) provided behind the recording medium (5). The data signal MS can likewise be obtained by the transilluminating method by means of a polariser (27) and two photodetectors (28, 29) provided behind the recording medium (5), by forming the difference between their output signals, whereas the data signal PS is obtained from the light reflected by the recording medium (5).

Title: Hot sprue assembly for an injection molding machine
Inventor: MORRISON ROCKY V
IPC: B29C45/26
Filed: 1991-03-14
Abstract: A hot sprue assembly is provided for controlling flow of molten material into the mold cavity of an injection molding machine. The hot sprue assembly is particularly designed for use with an injection molding machine for molding centrally apertured record discs, such as video information discs. The hot sprue assembly includes a hot sprue bushing cooperating with a dispersion head to define an open and relatively narrow annular gate through which molten material is injected into the mold cavity, and a central die plug within the mold cavity for cooperating with the dispersion head to mold a central aperture into the disc. Valving of the molten material through the gate is achieved by heating the sprue assembly to create a temperature differential which, during soldification of the material within the mold cavity, permits the material within the mold cavity to soldify up to the gate without substantial soldification of material within the sprue assembly. The gate is disposed at a plane recessed slightly from the general plane of the soldified disc to prevent any surface discontinuities arising by retraction of the sprue assembly when the mold cavity is opened from projecting above the general plane of the disc.
