Title: Improvements relating to electrically controlled oil burning apparatus
IPC: F23N5/24
Filed: 1932-09-27
Abstract: 407,106. Electrically controlling oilburners. MARSDEN, A., 68, Victoria Street, London. Sept. 27, 1932, No. 26833. [Class 75 (i).] An electrically driven and ignited oil-burning plant includes a single movable member tending a predetermined time after the burner motor has started to open switches in the motor and ignition circuits, and a mechanism responsive to the burner flame normally allowing operation of the ignition switch but preventing operation of the motor switch. In the apparatus shown the movable member consists of a rotor 2 carrying mercury switches 7, 8 arranged in the motor and ignition circuits respectively. On the closure of a switch 32, which may be, for example, a thermostatic switch arranged in the water space of the boiler heated by the burner, current can pass from the mains switch 12 to the burner motor 13, to the ignition transformer 16, to an electromagnet 6, and to a lamp 24, a resistance 23, and a coil 17 heating a metal bar 18. The rotor carries a laminated pole-piece 4 adjacent the electromagnet 6 but is prevented from being turned by the electromagnet 6 from the position shown by a hook 11 on its surface engaging a projection 10 on a lever 9. After a predetermined time the expansion of the bar 18 operates the lever 9 to raise the projection 10 and the rotor 2 will then turn until the polepiece 4 is opposite the electromagnet 6 and both switches 7, 8 are opened, unless ignition of the fuel has previously occurred when a thermally operated switch 25 in the path of the combustion gases closes the circuit to an electromagnet 5 which acts on a laminated pole piece 3 carried by the rotor 2. In these conditions the rotor when the parts 10, 11 are disengaged assumes an intermediate position in which the ignition switch 8 is open and the motor switch 7 remains closed, this being the position for normal operation until the switch 32 opens and the rotor is returned by an attached weight 30 to the starting position. Should the flame become extinguished the electromagnet 5 will be de-energized and the switch 7 will be opened as in the case of non- ignition. When the switch 7 opens the electromagnet 6 is also de-energized and the rotor is held by the engagement of the weight 30 with a stop 34. The rotor can then be returned to the starting position by the operator pressing a switch 28 to energize temporarily the electromagnet 5. The electromagnets may be replaced by bimetallic strips acting when heated to turn the rotor in. the same direction as the electromagnets.

Abstract: 952,627. Typewriters. PAILLARD S.A. Aug. 4, 1960 [Aug. 22, 1959], No. 27059/60. Heading B6F. A typewriter control device comprises a series of control members 3 each with a number of code elements 4 which determine a function, e.g. case shift, that the typewriter is to perform. As described each control member may have up to twenty code elements 4 which engage with twenty contact fingers 11 arranged in four rows of five. These fingers are only momentary in engagement with the control members 3 but are latched until the next operation of the assembly carrying the fingers. The machine function is effected through the closure of pairs of electrical contacts 12, 13 by the downward movement of certain of the twenty slide fingers 11 locked by notches 15 and the latching or locking grid 16. The fingers are all moved against the code elements 4 by the pivotal movement of a plate 5 operated by an electromagnet 9. The control members 3 are formed of a material so that the code elements 4 may be easily broken off to represent a particular code and determine which function the typewriter is to perform. The members 3 are mounted at letter-space intervals between blades 2 on the carriage 1 of the typewriter. The housing for the fingers 11 is also mounted so they can travel up and down the control elements 3 by the distance equivalent to four elements. This is effected by an electromagnet sliding the plate 5 along the spindle 7.

Title: Corrosion protection in water systems
Inventor: WILSON JOHN KENNETH
IPC: B01J47/00
Filed: 1960-08-05
Abstract: 909,218. Preventing corrosion. NAPIER & SON Ltd., D., and PERMUTIT CO. Ltd. July 20, 1961 [Aug. 5, 1960], No. 27290/60. Class 123 (1). A method of protecting from corrosion ferrous metal in contact with water which is particularly applicable to water systems such as engine-cooling or domestic water systems consists of introducing into the water an anion exchange resin loaded with a corrosion inhibiting anion, particularly a phosphate or chromate anion. Anion in the water which may cause corrosion, e.g. chloride ions, replace the phosphate or chromate anion which are released into the water and exert a corrosion inhibiting effect. Where the anion is that of a phosphate the water is preferably softened to avoid precipitation of calcium phosphate. The resin may be used in an acid phosphate form and preferably in a mono-substituted orthophosphate form. An example is given of the corrosion inhibiting effect of a weakly basic polystyrene bead resin of chloride form treated by percolation with sodium dihydrogen phosphate and suspended in a porous polyvinylchloride bag in water in a water-circulating system.

Motors, controlling. - Electrical means for actuating a jack for a dental, barber's or surgical chair, operating table &c., comprises a motor adapted to be reversed by shifting its brushes, a switch for controlling the motor supply circuit and an operating lever common to the brushes and switch. Trip mechanism is provided which opens the switch automatically when the jack completes its range of movement in either direction even if the operator retains the lever in an operative position. The brushes 4, 5 of the motor, Fig. 1, are resiliently mounted on arms 6, 7 of a brush-carrier 8 which is loosely mounted on an armature shaft 3. Motor 1 mav be of the series compensated type and is designed so that successive shifting of the brushes from the neutral position causes successive reversals in the direction of rotation of the shaft 3. Spring contact elements 8, 9 on the brush arms engage stationary contact elements 11, 12 on the motor frame 2. A switch 14 is in series circuit relation with a motor energizing circuit 15 including the elements 11, 12 and having a plug element 16 adapted to be connected to a live socket element 17. The switch includes a push button 18 which is normally maintained in an open position. The operating lever 19 is rotatable in a horizontal plane and is connected by the adjustable linkage 24 to the brush-carrier 8. The lever is held resiliently in the neutral position by a spring-actuated member 33, Fig. 3, engaging pins 34, 35. The switch is actuated by an extension 42 of the lever 19. Spaced shoulders 43, 44, Fig. 2, on the end of the arm 42 engage opposite sides of a horizontally disposed arm 45 which may be pivoted to a vertical shaft 46 for motion in a vertical plane. Arms 51, 52 carrying adjustable pins 53, 54 project from the lower end of the shaft 46. The pins 53, 54 engage pivoted links 55, 56, the free ends of which engage the push button 18.

Abstract: 529,704. Fluid-pressure servomotor-control systems. BRANDENBURGISCHE MOTORENWERKE GES. Sept. 23, 1938, No. 27830. Convention date, Sept. 23, 1937. [Class 135] The output of supercharged or high compression internal combustion engines, especially high altitude aircraft engines, is regulated in two stages, namely a lower output stage in which the throttle valve 9 is only manually actuated and a higher output stage in which the throttle valve is actuated by automatic adjustment of the charging pressure regulator to its predetermined datum. In the form shown in Fig. 1, the pilots' lever 13 is in non-rigid connection with two linkages, one comprising a lever 12, a link 11, and a cam lever 10 which adjusts the setting of the charging pressure regulator, and the other comprising a lever 18 and links 19, 14, 7 connected to the crank arm 8 of the throttle valve 9. The lever 18 is urged towards the lever 13 by a spring 16 whilst the linkage 11, 12 is similarly urged towards the pilots' lever 13 by a spring 20. The movement of the linkage 18, 19, 14, 7 is limited by stops 17 one of these corresponding to the closed position of the throttle valve. The charging pressure regulator comprises a pressure responsive chamber 1 which influences a fluid-pressure servomotor 2, 3 the working piston of which is linked to a guide crank 5 in turn connected by a link 6 to the links 7, 14. One of the links 6, 14 provides an abutment for the actuation of the throttle by the other link. In the modification, Fig. 4, the pilot's control is rigidly connected to the adjusting member of the charging pressure regulator through links 11, 21 and non-rigidly connected to the linkage 15, 14, 7 through a lever 22. In both forms the link 6 is the same length as the crank 5 with which it coincides in one position of the throttle, as shown the closed position, so that in this position the charging pressure regulator has an idle movement. If the charging pressure regulator sticks or its chamber 1 collapses the throttle 9 can always be operated manually.
