Title: Automated warehouse apparatus
IPC: B65G1/04
Filed: 1968-07-08
Abstract: 1,213,070. Selective signalling. LUMMUS CO. 8 July, 1968 [7 July, 1967], No. 32525/68. Heading G4H. In a load storing system having a rectangular array of load storing compartments, Figs. 1, 2, each compartment is addressed by an ordered pair of voltages significant by either amplitude (as described) or frequency (as mentioned) which are used either successively or simultaneously to position a carriage 40, alongside a selected compartment so that pallet lifting fingers 43, Fig. 1, can be extended to remove or to enter the load, and control of the positioning of the carriage is effected by comparing the voltages representing the compartment to which the carriage has to move with voltages representing the actual position of the carriage, these being obtained by wipers 56, 57; 71, 70, Fig. 4, from conductive segments 1b 2b . . ., 1a, 2a . . ., segment r being at a potential of r volts. The conductive segments 1b 2b . . ., Fig. 4, and also other conductive members 53, 66, 79 and s for controlling horizontal movement are carried by supports 110, Fig. 1, and those for controlling vertical movement by the carriage support frame 34, 35. For horizontal movement the desired position voltage is applied to conductor 53, Fig. 4, by a signal generator 55, and is compared under the control of logic on the carriage with the voltages picked up by brushes 56, 57, which are so spaced that both can just fit on to a single contact. When the voltages from both brushes equal the desired position voltage, movement is stopped. This results in fairly accurate positioning but for safety a check is made that the carriage is in registration with the main supports 108, Fig. 14, by comparing the outputs of two magnetic detectors 106, 107, any difference causing a corresponding correction to be made to the position of the carriage.

Title: Reverberatory smelting furnace and method of operating the same
IPC: F27B3/00
Filed: 1930-10-31
Abstract: 356,559. Charging reverberatory furnaces. DAVIS STEEL PROCESS CORPORATION, 25, Broad Street, New York, U.S.A. Oct. 31, 1930, No. 32797. Convention date, Nov. 23, 1929. [Class 51 (ii)] A reverberatory furnace has an elongated feed opening at one or both sides of the hearth with adjacent feeding mechanism, which is adapted to establish and maintain a sloping body of charge within the furnace without causing any substantial disturbance of the smelting face. In the construction shown the curved bottom plate 54 of the shoot 64 is supported by links 42, 44 pivoted to a fixed member 38, and oscillated from an hydraulic cylinder 56 through cranks 58, 60 and the link 62. The lower layers of material passing over the plate 54 are fed forward more rapidly than the upper layers, so that the free face of the material will be at an angle somewhat less than the angle of repose, and the centre about which the plate is oscillated is so chosen that the feed to the various levels of the free face corresponds with the smelting rate. A suitable rate of feed would be effected by one complete stroke of about inch every two minutes. The upper portion of the shoot may be fitted with vertical partitions such as 66 for stratifying the charge, and in the construction described these are so arranged that the main body of ore can be separated from the bottom and sides of the shoot by a layer of fuel. Roofs.-The roof 12 is brought closer to the hearth than is usual in the ordinary type of reverberatory furnaces, and is suspended from cross beams 20 by hanger arm 18 which support the skew-backs 16. The hanger arms are pivoted to the beams and they are pulled inwards by spring- pressed tie rods 26 passing through a block 30. Hearths.-The hearth is narrow, and has feed shelves 34 at the sides which are preferably overlapped by the roof. At one end of the hearth is a depression forming a settling pocket from which the reduced metal and slag are tapped.

Title: Apparatus for measuring frequency with oscillating electric crystals
IPC: G01R23/02
Filed: 1926-12-28
Abstract: 263,841. Radiofrequenz Ges., and Eberhard, H. Dec. 29, 1925, [Convention date]. Piezo-electric crystal units.-In an instrument in which resonance is detected bv the luminous effect produced by the mechanical oscillations of a piezo-electric crystal K, a glow-discharge lamp G is connected in parallel with the crystal in order to limit the voltage applied thereto and thus to protect the crystal from disintegration. The lamp G may contain a mixture of helium, neon, and mercury vapour. If the coupling between the transmitter S and the resonating circuit R is made initially tight, the glow-discharge lamp G is illuminated when approximate resonance is obtained. The coupling is then made loose, exact resonance is indicated by the lamp G ceasing to glow, owing to the extraction of energy therefrom by the oscillating crystal. A single glow-discharge lamp may be employed as a safety device and coarse-adjustment indicator for a number of crystals oscillating at different frequencies. The lamp G may be arranged adjacent to or structurally combined with the luminous tube in which the oscillating crystal is inserted, so that both phenomena of luminosity may be simultaneously observed.

Title: Improved method of treating low temperature tar and its distillates
IPC: C07C37/00
Filed: 1927-12-06
Abstract: 307,382. Morgan, G. T., and Pratt, D. D. Dec. 6, 1927. Pitch; tar. - The resinous or asphaltic constituents contained, in alkaline extracts of lowtemperature tar or its distillates are separated by salting out. Crude low-temperature tar or a distillate therefrom may be treated with a solvent for phenols which is a non-solvent for pitch, and the solution, after clarifying, may be treated with an aqueous solution of an alkali-metal hydroxide saturated with a neutral salt of an alkali metal; a distillate boiling up to 150‹ C. from low-temperature tar is the preferred solvent, although petrol or ether also may be used, and a 10-20 per cent caustic-soda solution saturated with common salt is the preferred aqueous solution. A modified procedure consists in first treating the organic solvent extract obtained as above with a solution of an alkaline-earth metal hydroxide saturated with a neutral salt of an alkali or alkaline-earth metal, such as lime water saturated with calcium chloride. Such a solution extracts only phenols of lower boiling point, the remainder being subsequently extracted as above. A further modification begins with the extraction of the low-temperature tar or distillate with caustic-soda solution in known manner. This extract is saturated with common salt, with or without a preliminary washing with an organic solvent, and filtered through common salt until clear; in this modification also the. double extraction with an alkaline-earth metal hydroxide and an alkali metal hydroxide may be applied. The pitch precipitated in these processes may be worked up by treatment with solvents or by distillation to vield lubricating or other oils and a harder pitch.

Title: Improvements in or relating to preparations of natural or artificial milk containingbacillus acidophilus
IPC: A23C11/10
Filed: 1934-11-16
Abstract: A milk-like product is prepared by adding b. acidophilus to soya bean milk and developing it therein until a vigorous growth has been attained and a palatable flavour produced.  The soya bean milk, which may be made by the process of Specification 30275/10, [Class 2 (iii)], is sterilized and about 2 per cent of lactose may be added to encourage growth of the bacteria and production of lactic acid. After inoculation with the culture of b. acidophilus a temperature of about 100 DEG  F. is maintained until the desired acidity is reached, usually in 10-15 hours.  The milk is then placed in a cool place to prevent further bacterial growth and development of too high an acidity.  The cultures prepared in soya bean milk may be used for inoculating cows' or goats' milk or a milk prepared from almonds, peanuts, cashew nuts or filberts.
