Title: Process for evaporation of liquid and condensation of vapour
Inventor: GRUNDY DEREK GEORGE RITCHIE
IPC: C02F1/16
Filed: 1964-07-08
Abstract: 1, 026, 375. Separation of solvent from solutions; distillation of water. LUMMUS CO. June 8, 1964, No. 23664/64. Heading B1B. Solvent is separated from a solution by passing the solution, in contact with an immiscible liquid which is hotter than the solution, upwards over alternate superposed trays E in a tower whereby some of the solvent vaporizes. The process is suitable for the separation of potable water from sea water using a hydrocarbon oil, e.g. kerosene, as heat-transfer medium (h.t.m.). At the top of the tower, the concentrated solution separates from the cool h.t.m. in phase separator UPS. The concentrated solution is withdrawn from the tower and is conveyed to the heat-exchange columns 10 and 11. The cool h.t.m. flows down the tower over trays H, which alternate with trays E; and the solvent vapours condense in contact with the h.t.m., thereby re-heating it. Trays H may be of the sieve type. The condensate, i.e. purified solvent, separates from the hot h.t.m. in the base of the tower. The condensate, withdrawn from the tower, is is conveyed to columns 12 and 13. The vapours evolved in the middle and lower sections of the tower do not leave it, but the vapours evolved on the upper trays E1. . . E3 pass through lines 31... 33 to compressors 25, and the compressed vapours are then conducted to the condenser trays H 9 ... H 11  in the lower section of the tower. The solution to be treated is introduced into the system by pump 3, and flows through tubes in columns 4 and 5, wherein it is preheated by spraying an auxiliary heat-exchange medium on to the tubes. The auxiliary heat-exchange medium is itself heated by spraying it, in columns 10... 13, over tubes through which the recovered solvent and the concentrated solution are passed before being withdrawn from the system. The preheated solution, withdrawn from column 5, is introduced into the tower through sparger 6. In an example relating to the distillation of sea water, the pressure in the top of the tower is 15 p.s.i.g. and the pressure at the bottom is 46. 5 p.s.i.g., the temperaturegradient being 218‹F.- 274‹F.

Abstract: 1285526 Automatic frequency control circuit SIEMENS ALBIS AG 19 April 1971 [26 March 1970] 23681/71 Heading H3A An A.F.C. circuit for a transceiver of a distance measuring system comprises a local oscillator 1 controlled by the output of a frequency discriminator 8, there being provided a hunting circuit for sweeping oscillator 1 consisting of a capacitor 2 and a resistor 3 connected via an amplifier 4 and a resistor 12 to the discriminator 8 and via a further resistor 6 to a blocking potential source - U. At a sub-station a switch 5 connecting source - U via a monostable circuit 9 to a control amplifier 4 is closed so that the amplifier is blocked and no charge voltage US exists across 2 so that oscillator 1 operates at its normal frequency f N  (Fig. 2, not shown). At the main station the switch 5 is opened, indicating a change in logical state from "1" to "0" and the monostable circuit 9 produces a positive pulse causing amplifier 4 to saturate and capacitor 2 to commence charging so that the oscillator frequency shifts from f N  to f E  on the other side of hunted frequency f H , which differs from f N  by the intermediate frequency to which circuits 11, 8 are tuned, the discriminator output being ineffective during the frequency shift as the amplifier 4 is already saturated. At the end of the pulse period, amplifier 4 is blocked and capacitor 2 starts discharging so that a sweep of the oscillator 1 commences from f E  till f H  when it falls within the capture range of the discriminator 8 when the discriminator output is allowed to pass via amplifier 4 for effecting automatic control of 1.

Abstract: 856,349. Making gas burners; punching. RADIATION Ltd. July 21, 1958 [July 26, 1957], No. 23779/57. Classes 83 (2) and 83 (4). In a method of making a gaseous fuel burner metal strip is formed into tube, inward pressure is applied to the tube to create outward pressure in an area of the burner where burner orifices are to be punched and the orifices punched while the pressure is applied. A stainless steel or brass burner tube of oval cross-section is perforated by punches 19 while located in a channel 12 between fixed and movable supporting members 3 and 4. Immediately prior to punching a cam-surface 16 on a strip 15 attached to the press-head 14, forces the spring-loaded member 4 towards the fixed member 3 which supports the upper portion of the tube by inducing a vertically directed outward force which resists the punching load. A resiliently-mounted punch guide 23 descends with the press-head and remains in contact with the members 3 and 4 until the punches are withdrawn. The punches 19 (Fig. 3, not shown) are mounted in a punch head 18 and secured by a member 19a and a collar 21, each punch being attached to a collar 21 by a circlip. Several burners may be perforated together, using a number of gripping members.

Abstract: 258,899. Armstrong, H. W. D., and Armstrong, S. E. Sept. 26, 1925, [Convention date]. Operating doors by treadles and weights and by cord arrangements.- The swing doors of a garage are coupled together to move in unison and are moved into the open position by the depression of treadles by the vehicle and into the closed position behind the vehicle by means of weights, a supplemental weighted cord being also provided to raise a crossbar into engagement with the outer face of the closed doors. The front and rear treadles 14, 23 rest on a crossbar 11 beneath the swinging doors 6 and when, by the entering vehicle, the bar 11 is depressed, a rope 35 at each side of the doorway and engaging a pulley 33 secured to the rod exerts a pull on a pulley 26 secured to the spindle of the door. The rope 35 at one end is secured to a weight 37 and at the other end to a weight 31, and the pulley 26 of each door is rigid with a pulley 27. An endless cable 40 is mounted in the pulley 27 of each door so that, as the vehicle moves into the garage, the doors 6 open in unison. When the vehicle has entered the garage and is off the inner treadles 23, the doors are closed by means of the weights 31 and cables 35. The weight operates to raise the cross-bar 11 and carry the member 13, Fig. 4, in front of the. doors to hold them closed. To ensure the doors being kept closed when the car is housed in the garage, the front wheels of the vehicle, as they engage with a stop block 41. are arranged to swing rearwardly a cross-bar 42 and thereby exert a pull on a cord 45 through the arms 42, 44. This causes a member 46 to be raised to the locking position beneath the cross-bar 11. Movement of the vehicle away from the block 41 allows the member 46 to be lowered by the counterweight 49, the doors then opening as the vehicle mounts on the treadles 23.

In a loom controlled electrically by the circuits disclosed in Specification 779,124, various operations are performed by electromagnetic clutches which slip when the load exceeds a predetermined value. Letting-off warp, Fig. 2. When the warp threads T become taut, they lift a wire X extending over them, thereby actuating a switch to close a clutch SC; the beam WB is driven until the warp becomes slack enough to sag on to a wire grill WG, depression of which operates a switch to disengage the clutch. Tensioning warp, Fig. 2. The warp threads pass between a brass shim BS and a soft iron bar SIB, a row of electromagnets EM causing the threads to be gripped to tension them. When warp is being let off from the beam WB, the strength of the magnets is increased. Warp stop motion, Fig. 2. Individuallysuspended weights SW interrupt a beam of light directed along a channel CH if any of them fall due to thread breakage, whereby a photocell stops the loom. Shedding. The heald shafts are actuated by cables wound on the hubs of slipping clutches ; at the end of the movement of a heald shaft, the clutch slips but maintains the lifting force on the shaft. Beat-up and take-up mechanism. The reed R, Fig. 5a, is actuated by a slipping clutch, whereby equal beat-up force is exerted on all picks in spite of the reduced stroke of the reed as successive picks are inserted without taking up the fabric. The top of the reed normally rides completely under a feeler TA pivoted on a spring-loaded plunger PN, the feeler being merely deflected, and returning to its vertical position when the reed has passed. When the fell has moved rearward sufficiently, the feeler remains in a groove in the top of the reed, so that as the reed moves rearwards after beat up, the feeler lifts the plunger PN to operate a switch RC, which energises a clutch to rotate the cloth beam. During takeup, the magnets EM, Fig. 2, are weakened.
