Title: Method of and apparatus for dehydrating aqueous solutions and suspensions of relatively low solids content
IPC: B01D9/04
Filed: 1954-09-07
Abstract: 778,301. Freeze-concentrating liquids. COMMONWEALTH ENGINEERING CO. OF OHIO. Sept. 7, 1954 [Sept. 14, 1953] No. 25933/54. Class 49 A process for dehydrating aqueous solutions and suspension of low solids content, e.g. fruit and vegetable juices, beers, wines, milk, coffee and aqueous pharmaceutical preparations, particularly valuable for concentrating such solutions or suspensions which contain volatile aromatic constituents, involves subjection of the solution or suspension to a series of refrigeration stages at decreasing temperatures, the temperature between stages being 5-7‹C. and the temperature at each stage being maintained constant, so as to freeze out water as a slush of ice crystals at each stage, separating the ice crystals after each freezing by use of a centrifuge with perforated side walls, and, at each centrifuging, removing residual solution or suspension from the ice crystals in the centrifuge by directing a blast of gas through the centrifuge walls, which gas may be heated sufficiently to melt the outermost layers of the crystals for better removal of adhering concentrate. In carrying out the process with the aid of the apparatus of Figs. 1 and 2, orange juice is treated in a first refrigeration tank 30 having therein three revolving hollow cylinders 150 through each of which is passed a refrigerating liquid, downwards by a central pipe 155 and upwards in an annular channel 156 between the wall of the pipe and the wall of the cylinder, having a stationary blade 180 near the outer surface of each revolving cylinder for prevention of ice deposition thereon, and having a central shaft 201 carrying a propeller blade 205, which, upon rotation of the shaft, agitates the juice undergoing refrigeration, and carrying also a loosely mounted disc 210, which, upon vertical reciprocation of the shaft 201 facilitates discharge of juice and ice slush from the base of the tank' 30, into a conduit 80 and to a centrifuge 90 having a screen wall 92; after centrifuging off the liquid and allowing it to flow into a tank 97, compressed air from an adaptor 130 is directed through the centrifuge wall, and the ice so detached is led off at a discharge opening 122; succeeding refrigerations of liquid in the tank 97 are effected in tanks 32, 33, 34 and 35 of progressively smaller capacity.

Abstract: 1472190 Telegraphic exchanges INTERNATIONAL STANDARD ELECTRIC CORP 13 June 1974 [20 June 1973] 26274/74 Heading H4P In a system for analyzing and storing message characters received in blocks at a telegraph switching centre, Fig. 1, each block includes a header which contains destination information as well as the message character, the received characters CAR each with the identity N1 of the line over which it was received are stored as CAR and N1 in fa1 Fig. 3 of a waiting queue memory FAR of a memory unit MEM, a signalling waiting queue memory FARS stores the identity of the line over which each character is to be transmitted, a character block unit BC reads characters from the reception waiting queue memory FAR each together with the identity of the line over which it was received and the character block unit BC examines each character for a header portion and addresses each character, together with a sequence indication SQ received from a line memory ML, to a translator TR. The translator provides for each character a new sequence indication SQ<SP>1</SP> and, if the character includes a header portion, a signalling indication. The character block unit BC stores each character in a buffer memory MTo-MTn and simultaneously updates the line memory ML with the new sequence indication and the header portion, if any, is stored, together with the identity of the line over which it is to be transmitted, in the signalling waiting queue memory FARS. As shown Figs. 1 and 3 the memory MEM which may be a ferrite core memory includes the reception waiting queue memory FAR, the line memory ML, an area of buffer memories MTo- MTn and the signalling waiting queue memory FASR. When a central processing unit or programme block BP is available it reads the signals including line number N1 in the queue memory FASR which signals resulting from analysis of the characters determines the switching operations for routing the message towards the outgoing line. The characters block BD, Fig. 3 includes a memory CAM including logic circuits for writing or reading requests for receiving in exchange an item of information indicating that the required operation is achieved, a register A in which an address to be selected in memory MEM is written and a memory register M in which is written the infornation to be transferred to or information to be read out of memory MEM. Auxiliary registers REG X, Y, Z temporarily store information read out from memory MEM by the character block BC and after a specified processing rewrites them in the memory MEM. Control logic circuits CLC include a time distributor DT providing clock pulses t 1 -t 5  and a sequence unit SQR formed by a chain of bi-stables and functioning in accordance with flow charts (Figs. 7 and 8, not shown). The line block BL is disclosed in Specification 1,205,193 and a telegraph message receiving and switching centre disclosed in Specification 1,450,428 is referred to.

Abstract: 1,177,844. Thermo-electric generators. SEIMENS A.G. 7 June, 1967 [8 June, 1966], No. 26387/67. Heading H1K. A plurality of thermocouples, each consisting of a pair of P- and N-type bodies 1, are mounted between a pair of heat exchangers 6 and 7 one of which is a fluid-filled conduit. To take up stresses caused by differential expansion the conduit consists of a tube with rigid portions spring-held against the respective couples, these rigid portions being joined by flexible tubing. In Fig. 1 the conduit 6 consists of a bellowslike corrugated tube, parts of which are made rigid by bonding complementarily corrugated rigid bodies 5 to it. These bodies rest on thermally conducting electrically insulating layers 3 of mica or aluminium oxide which in turn rest on the junction bridges 2 of the couples. They are spring held in such contact: either by the means shown in Fig. 2, and at the left hand side of Fig. 1, such means consisting of an outwardly open channel member 10a fitted with a blade spring 11; or by the means shown at the right hand side of Fig. 1, this means consisting of an inwardly open channel 10b whose web engages a helical spring 14. In both cases the channel is connected to the other heat exchanger 7 by screws 17 one of which is shown in Fig. 2. The washers 18 and spacers 19 associated with these screws are insulating and the screw itself should have a low thermal conductance. The couples are mounted on the other heat exchanger 7, which may be a rigid tube also acting as a fluid conduit, by bonding the bridge member 4 of each couple to an aluminium oxide layer 8 situated in a recess in the heat exchanger surface.  In Figs. 4 and 5 (not shown), the conduit 6 consists of rigid tube lengths joined by short bellows-like corrugated tube lengths, each rigid tube contacts two couples instead of the one engaged by the corresponding member in Fig. 1, and the second heat exchanger (7) is a rigid tube with a line of thermocouples displaced along each of a plurality of axially extending bounding lines of the tube, so that the tube is completely surrounded by couples.

Title: Improvements in or relating to apparatus for determining the frequency of electrical signals
Inventor: BROOKER ROBERT JAMES
IPC: G01R23/10
Filed: 1955-09-15
Abstract: 799,674. Frequency measuring. RANK CINTEL, Ltd., [formerly CINEMA-TELEVISION, Ltd.]. Sept. 14, 1956 [Sept. 15, 1955], No. 26434/55. Class 37. Apparatus for measuring the frequency of electric signals; particularly intermittent signals such as a keyed carrier in which each signal portion is too short for satisfactory measurements comprises a first means 5 operative only during the reception of input signals above a predetermined amplitude to allow these signals to be passed to a counter 8 and indicating means 9, and a second means 7 for applying constant frequency signals to a second counter means 11 which on receipt of a predetermined number of signals operates to prevent further application of the input signals to the first counter means 8. The incoming signal is passed through a gate 2 which is opened by a start pulse from 3 (supplied for example by an operator) and closed on receiving a suitable signal from counter 11. After passing through the gates the signal goes to a detector 4 and trigger 5 and also to gate 6. Trigger 5 opens gates 6 and 7 when the amplitude of the signal exceeds a predetermined value, and closes them when the strength of the signal falls below this value. The output of gate 6 is fed to counter chain 8 and the state of the count is indicated at 9 either continuously or on reception of the stop pulse from 11. Gate 7 controls the supply of a constant frequency source 10 to counter chain 11 and when the count on 11 reaches a certain predetermined value the stop pulse is produced which closes gate 2. The total time period provided by counter 11 being known, the indicator 9 may be used to determine the frequency. The start pulse received at 3 can be used to zero counters 8 and 11 and indicator 9. Preferably, this zeroizing is triggered by the leading edge of the start pulse and the opening of gate 2 by the trailing edge. Specification 743,528 is referred to.
