Title: Improvements in or relating to remote control systems for engines and machines
Inventor: ALDRED ALEC SANDERSON
IPC: G08B9/00
Filed: 1963-01-15
Abstract: 1,063,264. Remote control of engines, electrically. CHADBURNS (LIVERPOOL) Ltd. Jan. 8, 1964 [Jan. 15, 1963], No. 1876/63. Heading G1N. Relates to a system for the remote control of an engine e.g. from wheelhouse to engine room, having an arrangement to override signals from the remote control transmitter and cause the engine to stop or idle, in the event of abnormal cooling water temperature or oil pressure. The control handle of a wheelhouse transmitter is coupled to the movable brush of a potentiometer 19a (Fig. 5) which is connected with the field windings 21a, 21b of an electric motor 21 on an engine room receiver unit. The motor shaft is coupled through a clutch so as to move the brush of a potentiometer 33a, and also carries cams which actuate pneumatic valves connected respectively to act on the engine fuel supply governor and a gear lever on the propeller shaft gear box. As the potentiometer 19a brush is moved by the transmitter handle the circuit including potentiometer 33a becomes out of balance and there will be a change in current flow to a transistor 46 which amplifies the current which then passes from A-A to transistor 48 where it is further amplified and flows through the half field winding 21a causing the motor to rotate. The brush of potentiometer 33a is thereby moved until it is again in a balance position with the brush of 19a so that equal currents flow in the field windings 21a, 21b and the motor stops. During the adjustment to balance procedure the current to winding 21b will first be amplified by transistor 47, and then by transistor 49. Automatic Over-ridins of Control Signals. Water temperature and oil pressure sensitive switches 50 (Fig. 6) are connected so as to energize a relay 51 under abnormal conditions. The relay 51 switches a potentiometer 52 into the circuit of Fig. 5 at points XYZ, in place of the potentiometer 19a whereby a state of unbalance is created which causes the motor 21 to run until the controls are at the engine stop or idle position. The relay remains energized by a locking circuit until the transmitter handle is placed in neutral position. The control system also includes indication of over-run, or wrong direction, of the motor, also a means to provide a time delay with respect to the final balancing of the currents in the motor field windings.

Title: Method and device for the separation of a mixture of liquids having different boiling points
IPC: B01D3/14
Filed: 1926-01-22
Abstract: 271,130. Chur, E. Jan. 22, 1926. Liquids, treating with gases. - In separating mixtures of liquids such as tar oils, washing oils, &c., the liquid is passed from a pipe 4 down a main column A, Fig. 4, arranged so that the vapours generated also pass down the column, which is divided into sections. The vapours from the base of each section are drawn off through pipes 1, 2, 3, into separate condensing columns r, and the reflux from each of these columns is passed into the base of the succeeding condensing column. The main column is formed with passages a, b, c, Fig. 1, in the side walls. Steam for heating passes through the passages a and through spaces e below the plates. Liquid flows from plate to plate through passages c, and vapours flow downwards through passages b, h, and through pipes f immersed in the liquid on the plate below. The pipes may project into the spaces h to collect and remove condensates. In place of heating by steam, the liquid on each plate may be heated by being passed through tubes in a furnace flue or in the liquid or vapour space of a tar still. The tubes may be surrounded by a steam jacket, and the superheated steam formed in the jacket be used in the lower divisions of the column. The condensing columns in which the vapours pass upwards are formed with coolers k, Fig. 4, which take vapours from one plate of the column, partially condense these vapours, and return the condensate to a plate below and the uncondensed vapours to a plate above. The condensate from the base of the column passes by a pipe 9 into the base of the next condensing column, which receives hotter vapours.

IPC: H01H21/26
Filed: 1921-01-14
Abstract: 178,533. Parrish, E. W. Jan. 14, 1921. Road-traffic signals on vehicles.-In signalling apparatus for use on vehicles of the kind in which the circuits of lamps to indicate the direction of turning are initially closed by a switch and remain closed until the steering-wheel has returned to its central position, the initial completion of the circuit is by depression of a push 26 which forces down the armature 24 of a magnet 23 to maks contact at 25, 27. These contacts complete a circuit through the appropriate lamp and the magnet 23 in series so that the switch is held closed. Turning of the steering-wheel traverses a block 18 along a quick-pitched screw 17 to make. contact between blocks 13, 15, or 13, 16. This contact itself closes the lamp circuit and at the same time cuts out the magnet 23 so that when the steering-wheel moves the block 18 off either of the blocks 15, 16, the circuit of the lamp is broken. A separate lamp to indicate stopping is closed by contacts 35 on a disc 33 fixed on a rod 30 which slides against the action of a spring when the brake pedal 28 is depressed, contacts 35 being brought against fixed contacts 36.

Abstract: 1,019,835. Automatic exchange systems. SIEMENS & HALSKE A.G. Jan. 17, 1963 [Jan. 19, 1962], No. 2077/63. Heading H4K. In a three-dimensional matrix of magnetic ring cores employed for investigating the condition of trunks in a cross-bar system, the condition of each core indicates the idle or busy condition of a corresponding trunk, and the cores are threaded by three sets of conductors at right angles. To test the core S111, for example, positive pulses are applied over contacts x1 y1, and, if the core is in one condition, it is switched into the other condition, thus giving an output pulse at terminal z1 In order to restore the tested cores, additional conductors are connected to contacts z1 z2 &c. To restore the core S 111, negative pulses are applied over contacts x1 yl, zl, and at the same time positive pulses are applied over contacts z2 z3 &c. to avoid switching of other cores, e.g. S112 S113. The matrices relating to trunks interconnecting the successive switching stages may be incorporated in a single structure Figs. 4 5 (not shown).
