Title: Process of and apparatus for resolving solutions or liquid mixtures into their constituents by cooling and crystallisation
IPC: B01D9/00
Filed: 1934-10-25
Abstract: 429,474. Solidifying liquids by cooling. GES. FUR LINDE'S EISMASCHINEN AKT.- GES., H÷llriegelskreuth, near M³nich, and KRAUSE, G. A., 16, Widenmayerstrasse, Munich, Germany. Oct. 25, 1934, Nos. 30583 and 30584. Convention dates, Nov. 1, 1933 and April 9, 1934. [Class 29] A process for resolving a solution by freezing one or more of its constituents consists in cooling the solution in a mould until it is sufficiently frozen to be removed to a separator, e.g. a centrifuge, having the same form as the mould in which the liquid phase is separated from the solid phase. The mould is so cooled that the ice crystals formed in the solution lie in the direction in which the separating force acts. In the production of a milk concentrate, the milk may be frozen in an annular enamel mould 1 and removed by the member 2 to the basket of a centrifuge for the separation of the concentrate from the interstices between the ice crystals. The milk is frozen by immersing the moulds in a bath of cold brine which is circulated downwardly over the walls of the mould. The brine may be sprayed on to the walls of the moulds through pipes 18, 19, Fig. 5, and re-circulated by a pump 22. In order to prevent the formation of a crust of ice at the surfaces of the frozen milk, the mould may be provided with heatinsulating members such as 3, Fig. 1, and to prevent the formation of ice in the intersticed between the crystals during the washing or stripping operation, washing liquids having a freezing point below 0‹ C., are sprayed on to the frozen block which may, however, be finally washed with water. In a modification, the milk may be frozen in a disc mould and the frozen disc removed to a filter to the underside of which a suction pump is connected to withdraw the concentrate.

Title: Automatic telegraphy monitoring device
IPC: H04N5/76
Filed: 1972-06-29
Abstract: 1358355 Television monitoring arrangement T OHSAWA and M KARITA 29 June 1972 [3 July 1971] 30586/72 Heading H4F [Also in Division G4] A broadcasting monitoring device detects an audio or visual start and stop signal and between these signals filters the audio signal into predetermined frequency ranges, integrates and converts to a digital value the signal into each range and then codes and stores the values. The signals may be radio or TV and may be broadcast or transmitted by cable. The audio start signal is preferably two 20 nS duration pulses separated by and followed by a 20 nS portion of no signal inserted into the audio signal (Fig. 1, not shown) and the stop signal may be similar but with 10 nS duration. The visual signals are preferably white horizontal bars at predetermined positions on an otherwise black frame (Fig. 5, not shown). The system of Fig. 3 uses audio start and stop pulses on a TV signal. The audio signal is extracted from the audio detector 10 of a television receiver TV and is fed to start detector circuit A, stop detector circuit B and gate G. In start circuit A, the signal is band pass filtered at 13s at the frequency corresponding to 20 nS pulses and is shaped and rectified at 14s. The detection circuits comprise gate 15s, clock 16s, mark and space timing circuit 17s, 18s respectively and pattern detector 19s. These detect the start signal and when the full, correct start pattern has been received, an output is generated which sets bi-stable 20 and enables gate G. Stop circuit B functions in an identical manner; its output setting monostable 21 which resets bi-stable 20 and closes gate G. The audio signal passing through G is divided into channels 1 to n by filters 22. The signals are integrated at 23 to a level determined by Schmidt trigger 24 which then resets the integrator and supplies a pulse to counter 25. The counts in counters 25 after the stop signal are representative of the energy in each frequency channel and are characteristic of the signal. They are read into register D and then transferred by a pulse from monostable 21 into store E. When the start and stop pulses are video signals, the horizontal sync. pulses are integrated during each frame. When the integrated voltages exceeds a threshold, the arrival of the video voltage associated with the white bar opens a gate and the audio signal is again fed to the filter, integrator and counter circuits.

Title: Improvements in or relating to liquid dispensing apparatus
IPC: B01L3/02
Filed: 1960-09-08
Abstract: 946,109. Drop dispensing devices. DOSAMATIC DROPPER CORPORATION. Sept. 8, 1960 [Sept. 8, 1959; Dec. 23, 1959], No. 31036/60. Heading B8T. In a combined drop dispenser and bottle closure clap the amount by which the bulb can be depressed is adjustably limited to correspond to a desired amount to be dispensed. In Fig. 2 the flexible bulb 152 is secured in a rotatable and airtight manner to the cap 86 which carries a stop 108 having a pair of projecting arms 110, 112, cooperating with a stepped member 152 on the bulb. By rotating the bulb to bring different pairs of steps 170a opposite the arms 110, 112, the amount by which the bulb can be depressed before the steps contact the stop is adjustable, and hence adjustable amounts of liquid are drawn into the pipette 140. The pipette is carried by a resilient diaphragm 130, attached to the cap 86, which forms an air-tight seal between the cap and the end of the bottle neck, when the cap is tightened, and also prevents liquid flowing into the bulb through the air passage 106. The diaphragm 130 moves away from the passage 106, when the cap 86 is slackened, to connect the interior of the bulb to the pipette. The bulb carries markings co-operating with a stationary pointer 182, Fig. 1, to indicate the amount of liquid which will be drawn into the pipette for each setting of the bulb. In a modification, Fig. 7, the movement of the resilient cap 241 is limited by a helical surface 221, Fig. 8, co-operating with arms 231 on a plunger 230 carried by the cap 241. In Fig. 14 the movement of the bulb 271 is limited by a disc 275 with three legs 276 which engage three sets of grooves 274, Fig. 16, of different lengths formed on a sleeve 273 carried by the cap 270.

Title: Process for hydrogenating heavy hydrocarbon oil
IPC: C10G65/04
Filed: 1963-08-12
Abstract: Heavy hydrocarbon oils contaminated by asphaltenes and metallic impurities are contacted with hydrogen in a first stage in the presence of a solid catalyst containing at least one metal selected from Groups V(B), VI(B) and VIII, at 370-440 DEG  C. and 68-204 atmos., reacting at least a high boiling portion of the effluent from the first stage with hydrogen in a second stage at a temperature of 413-468 DEG  C., and higher than that in the first stage, in the presence of some of the same catalyst as used in the first stage, and returning high boiling oil from the second stage to the first stage. The first stage may be effected in partly vapour phase in a fluidized bed.  Stripped catalyst may be recycled from the second to the first stage. The catalyst may be nickel oxide-molybdenum oxide on a silica-alumina carrier, or the catalyst may be carrier-free and suspended in the oil, being the product of thermal decomposition of an oil-soluble compound of the metal, for example a carbonyl, acetylacetonate or xanthate.  This catalyst may be recirculated in suspension in heavy oil from the second to the first stage.

Filed: 1976-08-02
Abstract: 1491855 Straightening KAWECKI BERYLCO INDUSTRIES Inc 2 Aug 1976 [11 Aug 1975] 32123/76 Heading B3E Straightening apparatus comprises means for advancing an elongate workpiece while rotating it about its longitudinal axis, and a bending station comprising a rotatable infeed part having a passage for support of the workpiece, a rotatable outfeed part having a passage for support of the workpiece, such that the axis of the element assumes two different directions in the two passages, these directions lying in a plane, and a rotatable workpiece-confining member located at the intersection of the two directions. Figs. 1 and 2 are a plan and an elevation of an embodiment for straightening a tapered tube 90, Fig. 3, which is sheathed by a coil spring element 91 during straightening, such as to present a cylindrical outer surface and support the tube wall during straightening. Fig. 6 is a plan of the bending station. The sheathed tube is initially located in cylinder 16 rotated in bearing blocks 18, 20 by belt drive 26. Twin rams 40, 42 drive a cross-head 44 on which push-rod 30 is rotatably mounted, the rod being keyed to cylinder 16 and engaging the trailing end of the sheathed tube. Operation of the belt drive and rams thus rotates and advances the tube. The bending station comprises a yoke 62 rotating with cylinder 16, a yoke 64 rotatably mounted in blocks 82, and a central member 60 to which both yokes are pivoted as in a universal joint. The passage through member 60 is flared in a vertical plane at its inlet, and in a horizontal plane at its outlet 86a. Blocks 82 are mounted on a platform 50 rotatable about a vertical axis coincident with the pivotal axis 74 of yoke 64, such rotation being controlled by cam 102 moving with crosshead 44, through follower 106 and linkwork 108, 110, 114. The cam contour is such that at the beginning of a working stroke, link 108 is in position 108A, and the bending station passages are aligned, so that the sheathed tube can be fed in from the output end. As the stroke begins, follower 106 immediately rises, and sets yoke 64 at a maximum inclination suitable for the small diameter end of the tube. As the tube advances, this angle is reduced to suit the increasing diameter of the portion being straightened.
