Title: Method of making composite stock
IPC: B32B15/01
Filed: 1959-03-10
Abstract: 877,163. Making composite stock; rolling. TEXAS INSTRUMENTS Inc. March 10, 1959 [March 10, 1958], No. 8293/59. Classes 83 (2) and 83 (4). Composite stock consisting of a layer of silver adhered to one of ductile, non-porous silver halide (i.e. silver bromide, silver chloride or silver iodide) is made by melting the silver halide in contact with a layer of silver, cooling the assembly in the direction from the silver layer to the silver halide to solidify the halide and adhere it to the silver, and then rolling the assembly to eliminate porosity from the silver halide layer and submitting the assembly to a temperature within the range at which the silver halide remains free of porosity and good adherence between the silver and silver halide layers results. This range is 525-575 F. for silver bromide, about 68-425 F. for silver chloride and about 68-300 F. for silver iodide. For use in a battery, the silver layer of the composite stock may be bonded to a backing of corrosion-resistant metal by the method described in Specification 745,426. The assembly of the silver layer and the silver halide may be rolled at a temperature below, within or above the above respective range. The final rolling operation must be at a temperature within or below the above range in order to avoid porosity of the silver halide. If the final rolling temperature is within the range, it is unnecessary to again heat the stock to a temperature within the range unless it is desired to anneal the silver  layer. Several annealing steps may be effected during the rolling operation. Tellurium may be added to the silver bromide. As shown, a channel C is milled in a sheet 10 of silver and the ends of the channel closed by bars (Fig. 1, not shown) secured by welding. A layer of powdered silver bromide 18 is placed in the channel and covered by coarser grains 20 of the silver bromide. Heating to melt the silver bromide is by a furnace or over a flame, and differential cooling is by placing the sheet 10 on a copper &c. support and/or heating the surface of the silver bromide, as by gas flame. Before the final rolling operation, the stock is trimmed to remove the sides 14 and the ends. A reduction by rolling of over 99.5% is referred to.

Title: Method of refining mineral and shale oils, tar oils and the like
IPC: C10G17/06
Filed: 1947-04-02
Abstract: Mineral oils, shale oils, tar oils and the like are refined by a process comprising treating them with concentrated sulphuric acid (preferably of not less than 90 per cent by weight concentration) or with chloro-sulphonic acid in order to extract the more reactive components of the oil, and separating the solution (extract phase) from the treated oil (raffinate phase) by centrifuging before any noticeable chemical reaction (with subsequent solution of acid reaction products in the raffinate phase) has taken place.  The acid remaining in the raffinate phase is then allowed to react chemically with the more reactive constituents present in this phase and the sludge thus formed is removed from the raffinate phase by centrifuging.  Air may be blown through the raffinate while the chemical reaction is taking place and this air blowing may be continued until there is no noticeable formation of additional sludge and the sludge has been transformed into a state suitable for centrifuging.  The agglomeration of the sludge may also be accelerated by the addition of oxides, hydroxides, or metal salts, preferably of metals belonging to the first and second groups of the periodic system.  The de-sludged raffinate may be neutralized, for instance with lime, and the neutralization products removed by centrifuging, preferably while introducing water into the centrifuge. Specification 435,826 is referred to.

Abstract: 769,686. Reversing valves for regenerators. KOPPERS GES., H. April 2, 1953 [April 7, 1952], No. 9242/53. Class 64(1) In a regenerative coke oven, the fuel gas cock or cocks such as 13 which are open during any part of an operation cycle of the oven are so connected, e.g. by means including a chain 28, to the waste gas valve or valves 14 which are open during the same part of the cycle, that that valve or those valves are prevented from closing without prior closure of the said gas cocks or cocks. The connection is also such that the same waste gas valve or valves are re-opened when the said fuel gas cock or cocksare re-opened. In the form shown, the fuel gas cocks 13, 13a at opposite ends of a coke oven battery, the waste gas valves 14, and the air valves 10 are connected to levers 15, 15a, 17, the ends of which are engaged by pairs of stops such as 25 carried by endless chains 5, 6, 7 or rods, which are movable by a reversing machine 4. The pulleys 29, 29a, over which the chains 5, 6 actuating the' fuel gas valves pass, drive pulleys over which endless chains 28, 28a pass. These chains carry stops 30, 30a arranged so that they obstruct movement of the levers 17 and so prevent the waste gas valves 14 on one side of the coke oven battery from closing, until the fuel gas valves 13 or 13a on the other side of the battery are closed, even if the chain 7 or rods acting on the levers break.

Title: Device for Photoelectric Measurement of Absorption of Liquid Samples
Inventor: HRDINA JIRI
IPC: G01J3/42
Filed: 1967-02-28
Abstract: 1,183,472. Photo-electric, absorption analysis. CESKOSLOVENSKA AKADEMIE VED. Feb. 28, 1967, No. 9362/67. Heading G1A. [Also in Division G2] In apparatus for absorption analysis of liquid samples e. g. amino acids passed through a sample chamber 14, means are provided to compensate for the difference in transmitted intensity which is obtained when, for example, the chamber is changed for a layer or smaller one 14b or 14a or when the interference filter 16, used to carry out analysis in a particular spectral band, is changed for a different one, 16a or 16b. The compensation may be carried out by simultaneous movement into the light path of an appropriately adjusted attenuator, or effected electrically by switching in appropriate resistors or altering the light source supply. The invention is described with reference to a two-path system comprising a lamp 2 directing light via a collinating lens 9, attenuators 17, 18, 19 and interference filter 16, to a mirror 10, splitting the beam into one (the sample beam) passing through central aperture 11 and another (the reference beam), being reflected off at right angles to the original beam. The sample beam is focussed by lens 12 through diaphragm 14 on to the sample chamber 14, the light transmitted through which is detected by detector 13 e. g. a selenium photo-cell. The reference beam is monitored by photo-cell 15. The outputs of the cells are connected differentially to feed an amplifier 28 supplying a motor 30 which drives the wiper of a measuring potentiometer to maintain a balance between the outputs of the cells. This arrangement compensates for fluctuation in source intensity. Compensation for the differences in transmission when a different flow cell or filter is introduced is carried out in the following alternative ways. An appropriate grey filter 17, 17a and 17b may be provided with each interference filter and is moved into the parallel beam simultaneously with the interference filter. As this may provide only coarse correction, a fine control of compensation is provided by diaphragms 18, 18a or 18b and 14<SP>1</SP>, 14<SP>1</SP>a and 14<SP>1</SP>b or attenuators 19, 19a or 19b. The diaphragms have more effect on the intensity of the reference beam and attenuators than on the sample beam intensity. Typical attenuator and diaphragm devices are detailed in Figs.2 or 3 (not shown). Adjustment of these devices is made beforehand to provide immediate compensation when the interference filter or sample chamber is changed. Electrical methods of compensation include switching different value resistors into the lamp supply circuit (resistors 5) or into the photocell output circuits (resistors 20, 24). Figs. 4 and 5 (not shown) indicate alternative circuit configurations.
