Patent ES-310678-A1 (ES)
Title: Improvements relating to the cooling of the fuel jet nozzles of diesel engines
IPC: F02M53/04
Filed: 1965-03-17
Abstract: The fuel jet nozzles 17 of a diesel engine 1 are cooled by liquid in a closed circuit 20 .. 23 separate from the engine coolant and cooled by heat exchange at 16 with uncooled coolant liquid leaving the engine. The cooling system for the engine comprises a heat exchanger 2 from which cooled coolant is supplied to the cylinders through an inlet conduit 3 by a pump 5. Heated coolant from the cylinders is discharged through a conduit 4 and returned to the heat exchanger 2 through the heat exchanger 16 through which passes a coil in the circuit 20 .. 23 cooling the fuel jets 17. The two cooling circuits are maintained under pressure by elevated tanks 15, 25. A pump 22 circulates the cooling water for the fuel jets, and valves 9, 14, 12 are provided in the engine cooling circuit. In a modification the heat exchanger 16 is arranged as a by-pass across a restriction in the pipe 4.

Patent ES-315220-A1 (ES)
Title: Liquid pumping systems
IPC: F04D9/00
Filed: 1965-07-10
Abstract: A liquid pumping system comprises a centrifugal pump 1 driven by a turbine or electric motor and connected by a feed pipe 4 to the cargo or ballast tanks of a tanker ship. During discharge of the cargo, the liquid level in a separating chamber 3 is depressed by vapour accumulating therein, and the vapour pressure is communicated to a liquid level controller 7 which responds and sends out a pneumatic signal to various controls. Initially, the increasing signal pressure opens a diaphragm controlled valve 11 to communicate the chamber 3 with atmosphere via an intercepting chamber 13 having a moisture separator. Further increase in signal pressure closes switches 8 to a vacuum pump 6 which discharges the vapour together with pump sealing water to a separating tank 20 vented at 21 and containing a cooling coil 22 cooled by sea water. During final draining of the cargo tank the higher signal pressure, communicated through a selector relay 25, causes progressive closing of a valve 14 in the discharge line of the pump 1 and reduction in the pump speed. The valve 14 may be operated manually and locked in open, shut and draining positions. In the event of excessive temperature of the discharge from pump 1, a thermostat 23 stops the pump. Overloading of the pump 1, as by pumping high viscosity liquids, is avoided by applying an over-riding pneumatic signal through the selector relay 25 to the valve 14 to cause it to throttle the flow. This signal is applied either by a hand-set air regulator 26 connected to an air supply line 27, or by an electro-pneumatic device 28 which senses the driving motor current by a current transformer 29 and produces a suitable pneumatic signal through a controller 30. The pump may be shut down in an emergency by venting the pneumatic signal lines and isolating the air supply. A valve 18 prevents undue gasification due to excessive vacuum.

Abstract: A machine for making single strand barbed wire having a main strand and barbs wound thereon comprises a pair of wire forming rollers, means intermittently driving said rollers to advance and form the main strand of wire, and means for winding barbs on the main strand, the rollers at all times engaging the main strand to advance and precisely position it in relation to the barb winding means, the rollers also functioning to flatten the main strand at those places on which the barbs are to be wound. A line wire strand 56 is flattened to oval cross-section by intermittent feed rollers 52, 53, grooves 58, Fig. 14, in the rollers 52, 53 being interrupted by pairs of notches 59 to leave portions 60, Fig. 11, of the wire of circular cross-section separated by oval section portions 61 around which the barbs are wound. Three pairs of notches 59 are spaced around each roll 52, 53 and the rolls are rotated 120 degrees at a time by crank, link and braked ratchet means, Figs. 5-8 (not shown), from a main drive shaft 15. Barb forming wire 67 is fed to the wire 56 from two sides thereof by roller assemblies 70 and through guides 71 to a barb winding head 72 and barb cut-off knives 73. The roller assemblies 70 each includes a pair of rollers intermittently driven by eccentric, connecting rod and ratchet means, Fig. 16 (not shown), driven from the main shaft 15. The rollers serve also to flatten that side of the barb wire 67 which is to contact the strand wire 56 about which it is wound. The winding head 72 includes, Fig. 19, a hollow bar 145, through which the strand wire 56 passes, carrying axially projecting fingers 146 and rotated by a gear 135, driven from the main shaft 15, to wind the barbs from the wires 69. The bar 145 and thus the fingers 146 are suitably projected and retracted by a face cam 136 on the gear 135. The barbs are cut off after winding by the knives 73 which are moved forward by an eccentric, Fig. 20 (not shown). The completed barbed wire 56 passes over a pulley 180 on a spring-urged pivoted arm 181 to take up slack, around a driven pulley 176, over an axially reciprocated pulley 160 and on to a reel 163 rotated through a slip clutch. The arm carrying the pulley 180 may be positively oscillated by cam means, Figs. 24, 25 (not shown), for high-speed operation.
