Title: Engine for exchanging energy between fluids of different pressures
IPC: F01B3/00
Filed: 1968-12-06
Abstract: 1,241,453. Desalination by freezing. H. T. HASHEMI and J. L. LOTT. 6 Dec., 1968, No. 58015/68. Heading C1C. [Also in Division F1] In a saline solution in which initially the saline solution is mixed with a water imiscible substance such as a hydrocarbon in its solid form. When the particles of solid hydrocarbon are melted the latent heat of fusion absorbed from the solution goes to freeze out particles of pure ice and after the remaining brine solution is separated there is left a slurry of ice and liquid hydrocarbon. Pressure is then applied which freezes the hydrocarbon and effectively melts the ice. As shown in Fig. 4 a slurry of ice and liquid hydrocarbon is split and fed at low pressure via conduits 152, 154 to the two pumps 156, 158 constructed in accordance with the present invention which impart a high pressure to the two slurries which are then joined into a common conduit 164 which then leads to a highpressure pump 166. The function of the pump 166 is to impart to the slurry the residual pressure which was lost in the pump systems. The highly pressurized slurry is now separated at 170 by gravity and the separated fresh water transfers its energy to the incoming ice-hydrocarbon slurry moving through the pump 158 after which fresh water at atmospheric pressure is discharged to a suitable storage facility via conduit 174. Owing to significant reduction in volume of the mixture resulting from the freezing and melting processes it is necessary to add some fresh water at high pressure to the system. The separated hydrocarbon slurry is used in the same way to impart its energy to the ice-hydrocarbon slurry moving through the pump 156 after which it will be recycled to the first step of the exchange process. In such an operation the seal plates 58, 80 or even the entire stationary structure of the pump are maintained at a temperature below the freezing point of water and/or the hydrocarbon. The interior of the rotor is however kept at the temperature of the slurries. With this arrangement leakage between the end faces of the rotor and the seal plates will occur which will freeze to form a seal and further produce a disc of high lubricity. Lubrication and sealing functions can also be obtained from controlled leakage without freezing.

Abstract: 1,237,340. Audible signalling-apparatus. UNITED-CARR Inc. 12 Dec., 1969 [26 Dec., 1968], No. 60696/69. Heading G4F. An on-circuit buzzer device for use in automobile electric circuitry having circuits independent of the ignition circuit comprises a relay-type buzzer, the core 10 of which has two equal windings 11, 12 and which is adapted when magnetically energized to close normally open buzzer contacts 13, 14. Input terminal 15 is connected to the positive voltage of a lamp or other ignition independent circuit from which an inadvertence warning signal may be required and is in circuit by line 16, resistor 16a and line 17 with one of the buzzer contacts 13 and one lead 18 of one of the windings 11. Ignition terminal 19 is connected to the positive voltage of the ignition circuit and by line 20 with one lead 21 of the other winding 12. The other buzzer contact 14 and the other leads 22, 23 of windings 11, 12 are commonly connected by lines 24, 25 to control terminal 26 connected through a normally open control switch 27 such as a door switch to chassis ground 28. In operation, the circuit is inactive while the ignition is on because closure of switch 27 will energize only coil 12 holding contacts 13, 14 closed if there is no voltage output at input terminal 15. If voltage is at terminal 15 when ignition is on then contacts 13, 14 will not close because windings 11 and 12 are then in bucking relationship. Resistance 16a in input line 16 prevents short-circuiting the input terminal 15 to ground 28 when contacts 13, 14 are closed.

The point of connection of the tie rods and the beam 36 may be changed to maintain the position of the tie rods substantially constant, if the rollers are unduly displaced.
Patent GB-737850-A (GB)
Abstract: 737,850. Joint-making packing. SMITSVONK N.V. Dec. 3, 1953 [Dec. 19, 1952], No. 33590/53. Class 122 (3). [Also in Group XXVII] The packing provided between the cylinder 1 and cylinder head 2 is designed as a lowvoltage sparking plug and consists of an annular sheath 4 of copper for example, into which a heat resistant insulator 5, such as asbestos, mica or the material known under the Registered Trade Mark of " Permanite," has been pressed ; an electrode ring 6 which is embedded in the insulator 5 has a lip 7 for connection to the ignition lead. The holes through the electrode 6 for the cylinder and head securing bolts are larger than those through the sheath 4 and insulator 5 to prevent inadvertent sparking at these places. The inner edges of the sheath may be bent inwardly or the active surface of the electrode 6 made T-shaped in order to reduce the length of the insulator path over which the sparks travel. In a modification, each packing ring may comprise two or more separate insulated electrode rings and the bentover edges of the sheath may be cut away at places to prevent sparking occurring thereat. The plug is energized by a condenser 9 that is alternately connected to a charging circuit 10 and the electrode 6 by a throw-over switch 8 ; the electrodes may be actuated simultaneously each from a separate condenser. A similar result obtains by forming each electrode as a half-ring, the ends of which are spaced apart.
Patent GB-2003628-A (GB)
Title: Voltage control systems
IPC: H03K7/08
Filed: 1978-08-21
Abstract: A source for providing a voltage which is controlled by a digital signal includes a digital-to-analogue converter (30) which supplies a proportion of a voltage (VR) in accordance with the digital signal. The gain of an amplifier (48, 50) receiving an oscillatory signal is controlled by an error integrator (32) using an optical link (50) in dependence upon the difference between the converter output and a feedback signal derived via a rectifier (62) from a secondary winding (60) on an isolating transformer (56), the primary (54) of which is coupled to the amplifier output, so the feedback signal tracks the converter output. Another secondary winding (66) and rectifier (70) provide an output voltage equal to the feedback signal that tracks variations in voltage (VR). The output voltage can be used to control a voltage-controlled current source (74). <IMAGE>

Title: CO2 recovery process
IPC: C01B32/50
Filed: 1979-07-03
Abstract: A process for recovering up to substantially 100 molar % of the CO2 formed in a conventional ammonia production process by steam reforming a hydrocarbon feedstock and then subjecting the resulting gas stream to combustion with process air in a secondary reformer followed by at least one CO shift reaction includes the step of scrubbing the gas stream leaving at least one shift reaction with a physical solvent (eg. water, an inert ether or a dimethyl ether of a polyethyleneglycol), passing the solvent through a pressure reduction stage in which the solvent releases the majority of the CO2 dissolved therein, and then stripping the dissolved CO2 from the physical solvent with the process air being fed to the secondary reformer. Preferably the hydrocarbon feedstock is natural gas and the recovered CO2 is used for urea production by reaction with the ammonia formed in the basic process.
