Abstract: 1,028,254. Cooling gases by direct contact with water. LEUNA-WERKE "WALTER ULBRIGHT." VEBApril 1, 1964, No. 13393/64. Heading F4K. In a process for removing the heat generated when gases are compressed in multi-stage compressors, which uses direct contact between the gases and cooling water, but is so designed as to overcome the problem of water hammer, a pump 9 provides high-pressure cooling water, which is controlled by a throttle valve 10 so that it is sprayed from a sprinkler 5 in a cooler 3 at the same pressure as the gases, which have passed through a pressure pipe 1 of a first compressor stage, via an optional oil separator 2, to cooler 3, containing Raschig rings 4. The gases then pass through a shallow layer of Raschig rings 6, to separate any water particles, and thence, through pipe 8, to a second compressor stage. The water leaves cooler 3 through pipe 11 and is expanded in a degasification tank 12, the gases thus released, if valuable, may be conveyed, through pipe 13, back to the first compressor stage.

Title: Negative Resistance Amplifier
IPC: H04J3/20
Filed: 1967-03-22
Abstract: 1,182,336. Negative resistance amplifiers. INTERNATIONAL STANDARD ELECTRIC CORP. 22 March, 1967 [25 March, 1966], No. 13458/67. Heading H4R. In a negative resistance amplifier which is used in conjunction with a reactive storage device in an energy transfer network in a T.D.M. communication system, the negative resistance, when coupled to the storage device to provide amplification of the energy stored therein, forms an arrangement which includes a capacitance shunted by a negative resistance. such that the combination is short-circuit stable, or the electrical dual of a capacitance shunted by a negative resistance. Fig. 5, shows an embodiment in which after S 3  has been closed for a short time to store a signal sample in storage capacitor C, S 2  is closed to allow the capacitor to discharge for a short time before switch S 1  is opened to couple in the negative resistance -G to amplify the sample, then switch S 1  is closed, S 2  is opened, and the amplified sample transferred, e.g. by resonant transfer, from the circuit to a load by closing S 4  for a short time. A circuit using an inductor as the energy storage element is shown in Fig. 7 and this circuit uses the dual of a capacitance in shunt with the negative resistance, i.e. an inductance LC in series with the negative resistance - R, forming a circuit which is opencircuit stable. A circuit for the reflectionless amplified transfer of energy between two storage capacitors C 1  and C 2  is shown in Fig. 8 in which amplification is obtained if open-circuit stable negative impedances are provided in the series branches, and short-circuit stable negative impedances in the parallel branch, R 1 , R 2  and (R 0 /2), being negative resistances and R<SP>1</SP> 1  and   R<SP>1</SP> 2  positive. Transfer takes place when S 3  and S 4  are closed simultaneously while S 1  is opened. In this type of circuit the gain may be changed by switching additional resistances in parallel with the negative resistances, e.g. when a call has been connected, Fig. 9 (not shown).

Sunken ships, raising.-The open-bottomed air tank 1, Fig. 1, used with the submarine tractor 31 described in Specification 146,063 is provided with an air-supply siphon 7, an electric device 3 for indicating the water-level, an equalizer bar 21 to which are attached the lifting-cables 22, and a support 19 upon which the tank may rest on the sea bottom. Sufficient water having been admitted to the tank 1 to cause it to sink, it is lowered by the cable 12 attached to the siphon 7 on which the lower edge of the tank rests, being guided if necessary by a cable 17 winding on a winch 16 on the tractor 32. The water-level, as indicated by the contact 3 and bell 6, is kept constant during the descent by admitting air from the cylinder 9 through the pipe 8 and siphon 7. When the support 19 rests on the bottom, the siphon is disengaged and hauled up to lower another tank. The tanks are then carried into position against the wreck by being engaged with the lug 36, Fig. 4, of the movable bar 35 on the tractor, and the hooks 23 inserted into previously drilled holes by means of the cranked rod 30. The siphon 7, which has a base 20 adapted to rest on the sea bottom, is then picked up by the bar 30 and carried successively into position under the tanks which are thus filled with air. In a modification of the apparatus, the air tank 1, Fig. 6, is partially filled with air, hooked on to the air buoy 55, and drawn down against its reserve buoyancy by the cable 59 of the winch 60, the hooks 50 being then inserted into the holes as before. To indicate whether the determined buoyancy of the tank is being maintained during lowering, measuring instruments are included in the circuit of the electric motor 64 which drives the winch 60. When in position the tank is supplied with air by the pipe 53 through the buoy 55.

Abstract: 134,258. Salmon, P., and Smith, W. S. Aug. 30, 1918. Apparatus.-Relates to an automatic control for propellers of variable pitch. An oil or other fluid pump a is driven by an auxiliary propeller b and is adapted to force liquid through the passage h<2> into the space c' so as to move the piston d against the action of the spring g. The piston rod e is attached to the cross-head f, which is connected by links to the blades of the main propeller of an aeroplane. When the engine is started on the ground, the auxiliary propeller b remains stationary and the pump rotates on its spindle, a comparatively small amount of oil being pumped to the space c'. When the aeroplane moves forward, the air rotates the propeller b in the opposite direction to the main propeller, the boss of which carries the body of the apparatus. The delivery of the pump is increased and the piston d moves further to the left and regulates the pitch of the propeller blades. An independent or finer adjustment of the propeller may be made by hand. The valve i controls the flow through the ports k<2>, k<1> from one side of the piston to the other, and consequently the position of the piston. The valve i may be adjusted by a fork-and-sleeve device l operated by the pilot. The by-pass may also be automatically controlled by a centrifugal governor m, n.
