Abstract: 295,252. Batty, D. E., and Associated Equipment Co., Ltd. May 7, 1927. Supplying consuming-devices from variablespeed generators. - A generating system for omnibus and like vehicles, and for other purposes, designed to give the required output at low speeds and to be immune from excessive sparking at high speeds, comprises a prime mover with a large speed range driving a plurality of generating elements each of which gives the required voltage at a different speed. The system may comprise a single machine with two windings and commutators with a single armature and a singel field system. The preferred arrangement comprises an auxiliary generator which becomes operative at about 250 r.p.m., a main generator which operates in parallel therewith from 500 (or 800) r.p.m. and speed controlled switching arrangements to render the auxiliary machine inoperative at 2000 (or 2600) r.p.m. The main machine may have an auxiliary exciting winding carrying the load current of the auxiliary machine. Fig. 1 shows an auxiliary three-brush machine the field circuit of which is closed at 250 r.p.m. by a speed-controlled switch 19. The machine is then connected to the battery 12 through the auxiliary field 16 of the main machine 11. At 500 r.p.m. the machine 11 is cut-in by the magnetic cut-out 13. The shunt field 14 of the main machine has a voltage regulator 15. The output of the auxiliary machine falls off as the speed rises according to the curve 20 in Fig. 2, the curve 21 representing the output of the main machine, and at 2000 r.p.m. the switch 19 disconnects it from the load circuit. In a modification the auxiliary machine is a shunt wound dynamo with a field regulator. Its load circuit is controlled by a magnetic cutout and a resistance is inserted in its field circuit to reduce its output at about 2000 r.p.m. by a speed-controlled switch. More than one auxiliary machine may be employed.

Filed: 1952-05-19
Abstract: Apparatus for distilling liquids, particularly for distilling sea water in lifeboats, comprises a boiler (or two or more superposed boilers in multiple effect), and valves controlling the admission of liquid to the boiler, the overflow of liquid from the boiler when a desired level has been reached, and the discharge of liquid from the boiler, the valves being operated by a single control having three positions corresponding to admission of liquid and overflow, <PICT:0732916/III/1> discharge of liquid and distillation (all valves shut).  As shown, two boilers 10, 11 are provided separated by a heat-insulating pad.  A vertical valve chest 26 has pairs of opposed pipe unions which may communicate through holes in a slide-bar 42 raised and lowered by a rack and pinion operated by handle 50.  The boilers are surrounded by a casing 18 the upper part 21 of which constitutes a reservoir for feed water in which is disposed a condensing coil 63.  In one position of the slide-bar 42 the pairs of pipes 25, and 25a, 27 and 27a, 28 and 28a, and 31 and 31a are in communication so that water can flow from reservoir 21 to fill boiler 10 by pipes 25, 25a, overflow from boiler 10 when the correct level is reached flowing by pipes 27-28a to fill boiler 11.  When boiler 11 is full to the correct level, overflow discharges by pipes 31, 31a and 33.  The valves are then shut and distillation started.  To discharge concentrated brine the handle 50 is moved to its third position to allow pairs of discharge pipes 34a and 34, and 35a and 35 to communicate, the brine discharging to pipe 33.  At the same time pairs of pipes 27 and 27a, and 28 and 28a also communicate to allow air to enter the boilers by vent pipes 38.  Vapours from boiler 11 are taken to a coil in boiler 10 to heat the water therein, the end of the coil being connected by pipe 59 to valve 60 which maintains the required pressure in boiler 11.  From valve 60 a pipe 62 leads to condenser coil 63.  Steam from boiler 10 is taken to coil 63 by pipe 66.  Stainless metal gauges are disposed just above the liquid levels in the boilers to prevent frothing.  The boilers are heated by burners 71, the hot gases passing around the boilers and in the case of the lower boiler 11 between the wall of this boiler and a corrugated surrounding cylinder 13.  In a modification a rotary valve replaces the slide valve.

Abstract: 435,421. Machines for making cables. NORDDEUTSCHE SEEKABELWERKE AKT.-GES., Nordenham, Oldenburg, Germany. April 26, 1934, No. 12591. Convention date, June 21, 1933. [Class 109] [See also Group XXXVI] In a stranding-machine for making a stranded high-frequency conductor of the kind in which the individually insulated wires, when seen in a number of successive crosssections of the conductor, follow cyclically one behind the other along a closed curve through the entire cross-section of the conductor or a sector thereof, the bobbins of the stranding machine are moved by chains in guides in the bobbin-head in such a manner that they travel one behind the other along a closed curve similar in shape to the path traversed by a wire in the finished conductor. Fig. 2 shows a conductor comprising two stranded semicircular cores laid around a central wire a in which the wires of each core follow cyclically along one or the other of the closed paths b. Such a conductor may be produced by a machine having a stationary bobbin-head 1, Figs. 3 and 4, provided with crescent-shaped slots 2 around which traverse the bobbin holders 4 carrying the wires 7 for each core. The bobbin holders are connected together by a chain 14 which is driven by rollers 9. The wires 7 are laid about the central wire a by rotating the take-off device 10 to which a stranding die 11 is attached. A tube 12, through which the central wire a passes, projects towards the die 11 to prevent stranding of the cores taking place in advance of the die 11. In a modified construction the bobbin-head 1 is rotated instead of the die 11.
