Title: Improvements in or relating to bottling and like machinery
Inventor: BROOKES-SMITH COLIN HECTOR WIL
IPC: B67C7/00
Filed: 1948-02-11
Abstract: 647,977. Electric tests. SOUTHERN INSTRUMENTS, Ltd. Feb. 11, 1948, No. 4063. [Class 37] [Also in Group XL (b)] Insulating containers, e.g. milk bottles are tested for a correct filling by causing the liquid to form one of the electrodes of a condenser. Each bottle is examined by passing it between two spaced electrodes 5 and 2 so that the liquid forms the central electrode of a pair of series condensers. The condenser is connected in parallel with an inductance 4 and supplied from an oscillator 3 so that the correct quantity of liquid x brings the circuit to resonance or alternatively disturbs it, the voltage change across the circuit being rectified. In addition the bottles may be tested for the presence of the sealing cap, the top of each bottle passing between a pair of limbs of. an E-type transformer, the primaries of which are oppositely wound on the outside limbs. The unbalance current in the secondary caused by the presence of the metal top of the bottle in one leg of the inductive circuit is amplified and used to operate a relay. The cap of the bottle may also form with a fixed electrode, a condenser, the arrival of a bottle bringing a tuned circuit to resonance and operating a relay. An arrangement is described with reference to Fig. 3 (not shown), in which bottles are counted, by interrupting a beam of light to a photo-cell, the counting relay however operates only if its circuit has been previously prepared by the relays testing for correct filling and the presence of the metal cap. Alarms are provided to show which one of the relays is unoperated. In a modification of this last arrangement Fig. 4, not shown), a relay may be connected in the common anode circuit of a pair of valves rendered conductive or non-conductive respectively by the connector filling and the presence of the metal cap. The relay is operated only when both conditions are fulfilled.

Abstract: 1,218,444. Stabilizing exposed photographic silver halide materials. EASTMAN KODAK CO. Jan. 26, 1968 [Jan. 27, 1967], No. 4271/68. Heading G2C. A light-sensitive heat-stabilizable photographic silver halide material comprises a silver halide emulsion layer and a contiguous layer containing per mole of silver halide at least one mole of a stabilizer precursor, which is a sulphur-containing organic compound which breaks down at elevated temperatures to form a compound which combines with unexposed silver halide to form a light-stable silver mercaptide, and at least one quarter mole of an activator precursor which is a compound which breaks down at temperatures above about 90C. to form an alkaline compound, which aids in the breakdown of the stabilizer precursor. After exposure and development, the materials can be stabilized by heating, the stabilization being more quickly effected than materials in which an activator precursor is absent. Stabilizer precursors specified include those specified in Specification 1,113, 603, e. g. 3-S-thiuronium propane sulphonate and 2-hydroxyethyl isothiuronium trichloroacetate, and activator precursors include guanidinium salts, e. g. the trichloroacetate and oxalate, quaternary ammonium malonates, e. g. piperidinium malonate, amine malonates, amino acids, heat cleavable hydrazides oxazolidone and sodium trichloroacetate. The materials may be developed by applying a thin layer of developer and then be stabilized by heat or a developing agent may be incorporated in the material which is then heat-developed and heatstabilized.

Title: Silica sols and refractory materials prepared therewith
IPC: C04B35/63
Filed: 1961-02-06
Abstract: Silica sols in a dispersion medium comprising an oxygen-containing solvent miscible or partially miscible with water, and substantially no inorganic salts, are prepared by conventionally forming a silica organo-hydrosol sol containing inorganic salts, adding a quantity of said solvent such as to precipitate or flocculate said salts.  The original sol may be prepared by acidifying an inorganic silicate, e.g. with hydrochloric or sulphuric acid and adding a salt of the acid used together with an organic dispersing medium for the silica to salt out the water; the organo-hydrosol may be separated by decantation and subjected to osmosis to remove water.  The purified sol produced by the method of the invention may be dehydrated and/or concentrated (a) by addition of ethyl silicate, (b) by addition of SiCl4 and subsequently removing the hydrochloric acid formed by blowing in dry air or by passing through an anion exchanger in hydroxyl form, or (c) by adding an organic solvent miscible with the oxygen-containing organic solvent but which does not serve as a dispersion medium for the silica, and separating the layers which form; (c) may if desired by followed by (a) or (b).  Specified oxygen-containing solvents are methyl, ethyl, n- and i-propyl, t-butyl alcohols, acetone and dioxane.  Specified solvents miscible therewith are turpentine, trichlorethylene, diisobutylene and benzene.  The sols may be stabilized by addition of aluminium salts, e.g. the chloride, acetate or isopropylate. The organic liquid in the original sol may be acetone, t-butyl alcohol and i-propyl alcohol. The sols may be employed as bonding agents for metals or refractory materials, e.g. to form furnace elements or catalysts. For furnace elements the powdered refractory, e.g. a mixture of zirconiferous sand and zirconia, may be incorporated with the sol and a small amount of magnesia added as a setting accelerator, to form a paste which can be poured into moulds subjected to vibration or compacting by a ram.  After hardening, the product is dried to remove solvent, and produce a dense element. For elements, such as catalyst spheres, of greater porosity, powdered alumina may be mixed with the sol and magnesia added as a setting accelerator; the mixture is poured into moulds, removed therefrom after hardening, which may be after 1 minute, and calcined to give spheres having a porosity of 42%.ALSO:Silica sols composed of colloidal silica, organic solvents and water (see Division C1) may be applied alone or mixed with powdered materials, e.g. metals or metallic oxides, to form sealing or protective coatings on parts to be heated to a high temperature, by spraying, brushing or impregnating in vacuo.
