Title: Improvements relating to oil-engine driven locomotives
IPC: B61C9/14
Filed: 1922-07-20
Abstract: 190,981. Schneider, H. July 20, 1922. Hydraulic and pneumatic transmission apparatus; transmission gear between separate axles; reversing-gearing. - Comprises transmission gear for locomotives driven by oil engines. Fig. 2 shows one construction in which two longitudinally-arranged engines drive the primary members 6 of a pair of nuid-transmission members, the secondary members 7 of which are connected together and to the externally-toothed casing 10. The casing transmits the drive through pinions 11 to longitudinal shafts 12 geared by bevel or worm gear to the shaft of each driving-wheel. Fig. 5 shows another construction providing for change-speed and reversing. A single, preferably non-reversible motor, is used in conjunction with two fluid-pressure transmission members 110, 120, either of which can be rendered operative or run idle at will, by admitting or discharging nuid to or from its interior. For slow speed forward running, the member 120 is operative, and 110 idle. The shaft 130 is driven in this case through a spur train and the shaft-coupling clutch 135, part of the power being re-transmitted through the spur gear of the idle transmission member to the longitudinal shaft 140 on the opposite side of the vehicle. To reverse, the coupling crutch 145 is connected and 135 disconnected. The shaft 140 then is driven through a reversing spur train from the member 120, part of the power being retransmitted to the shaft 130. For high-speed for. ward driving the member 110 is made operative and 120 idle. Both longitudinal shafts then are driven from the member 110. The use of a reversible oil-engine which would allow certain of the gear trains in Fig. 5 to be omitted is referred to. The making use of the reversing-gear to serve as a third slow speed forward drive, by reversing the engine, also is described. By rendering both fluid transmission gears operative at the same time and manipulating the two couplings so that the transmission gears rotate in opposite directions, a braking effect can be obtained. In some cases one end only of each wheel axle may be driven.

Title: Improvements in and relating to electric circuit breakers
IPC: H01H71/70
Filed: 1930-07-01
Abstract: 357,287. Automatic circuit-breakers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hilliard, J. D. ; Hotel Hough, Schenectady, New York, U.S.A.) July 1, 1930, No. 19966. Convention date, July I, 1929. [Class 38 (v).] 0 i l switches ; electricmotor actuation; locking and unlocking.- A circuit-breaker is closed by means of a rotating shaft carrying a flywheel and a cam, a disengageable thrusttransmitting member being inserted between the cam and the operating - member of the circuitbreaker whereby the kinetic energy of the flywheel is imparted to the latter. Closure of contacts 23, 24 energizes a motor 8 which speeds up a flywheel 7 driving a cam 11 through reductiongearing. Closure of contacts 23, 25, de-energizes the motor and energizes a solenoid 6a which moves a toggle 6 out of locking-engagement with the switch operating-member 1 and also makes at 31, 32 a circuit over closed contacts 29, 30 for a solenoid 22. The latter attracts its core 21 and rotates a bellcrank lever 14 against the action of a spring 16 so that a member 12 pivoted to the end of the member 1 is moved into the path of the cam 11. The energy of the flywheel, acting through the cam and member 12, moves the member 1 upwards in a straight line at a uniform speed or with harmonic motion, depending on the cam. The switch is retained closed by a locking-toggle 5, and in this position the solenoid 5a is de-energized (by means not shown), so that the circuit of solenoid 22 is broken at contacts 29, 30. To open the switch, a pushbutton switch is closed to energize the solenoid 5a and free the latch 5, the switch opening under gravity, aided, if desired, by a spring.

Title: Improvements in or relating to methods of applying light-diffusing layers to glass surfaces
IPC: H01K3/00
Filed: 1954-07-08
Abstract: 754,369. Electric incandescent lamps. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 8, 1954 [July 9, 1953], No. 20010/54. Class 39(2). [Also in Group XV] In order to improve the adhesion of a lightdiffusing coating produced upon a glass surface, such as the interior surface of a lamp bulb, by burning magnesium or magnesium alloys whereby finely divided magnesium oxide is deposited, the glass surface is .treated with. gaseous oxidation products of phosphorus, either during or prior to the deposition of the magnesium oxide. The treatment with the gaseous oxidation products of phosphorus is preferably carried out simultaneously with the application of the magnesium oxide, since the temperatures are then sufficient to ensure the reaction of the oxidation products with the glass surface. When the phosphorus is burned in the bulb beforehand it may be necessary to heat the glass to a temperature exceeding 150‹C. during, or for some time after, that treatment in order to obtain the desired action upon the glass. Satisfactory adhesion may be obtained by burning 15 milligrams of red or white phosphorus within a bulb having a surface area of about 100 square centimetres. Alternatively phosphorus compounds e.g. PzOs, P 2 O 5  or PH 3  may be used in amounts sufficient to yield the necessary quantities of oxidation products. The magnesium oxide may be applied to the glass surface by burning alloys of magnesium with other metals, e.g. lithium, aluminium, silicon &c., relative compositions of which are given in the Specification. Preferably the glass surfaces upon which the coatings are to be deposited are previously rendered light diffusing by etching. The magnesium or magnesium alloy, and the substances that produce oxidation products of phosphorus by combustion may be burnt in a container of quartz, tungsten, tantalum or similar refractory materials within the bulb, and the heat for combustion initiated electrically by a filament, carbon arc, high frequency heating or, as shown in Fig. 1, by passing current through a metal container 7 in which the materials are placed. The neck of the inverted bulb 3 is fitted upon a holder 2 on a stand 1, and the container 7, which is made of tungsten and supported upon two insulated current supply conductors 5, 6, is introduced through the aperture in the holder 2. A supply of oxygen and/or air for combustion is fed through a tube 4 located between the conductors 5, 6. Alternatively a supply of gases which yield oxidation products of phosphorus may be fed through the tube 4.

Title: Improvements in type line composing and casting machines
IPC: B41B11/38
Filed: 1932-07-15
Abstract: 388,993. Type-bar-making machines. INTERTYPE CORPORATION, 360, Furman Street, Brooklyn, New York, U.S.A. July 15, 1932, No. 20105. Convention date, Nov. 9, 1931. [Class 100 (iii).] Clamping matrices.-In means for quadding out and centralizing short lines, a single pawl is adapted to impart the clamping movement either to the right-hand jaw or to both jaws, according to whether a line is to be indented at the end only, or is to be centralized. The jaws 2, 3, Fig. 1, have rack-bars 5, 6, which can be connected by a slidably mounted pinion 7 when both jaws are to be moved, and the right-hand jaw 3 has closing mechanism similar to that described in the prior Specification. The rack-bar 6 has on its underside teeth 42, which can be engaged by a pawl 41, mounted so as to move obliquely in a bracket 40, which is carried by one of the rods 37 that support the justifying-bar 39. The pawl 41 is held in raised position by a spring, so that, as the justifying-bar rises, the pawl first engages the teeth 42, and is then forced to the left, carrying the rack-bar 6 and jaw 3 with it, so as to clamp the line. If the pinion 7 is in operative position, both jaws are moved towards each other. In a modification, designed to avoid wide-spacing between words, the bracket 40a, Fig. 5, that supports the pawl 41, is carried by a post 50, which can slide vertically in a guide 52 on the vice-frame. A plunger 55, guided to move horizontally through the bracket 40a, is adapted to be moved by means of a hand-lever 57 into and out of the path of a member 39a attached to the justifying-bar 39. The arrangement is such that, when the plunger 55 is projected the pawl 41 is brought into engagement with the rack-bar 6 before the spacebands have been driven upwards to the full extent. When full-length lines containing spacebands are to be cast from, the plunger 55 is withdrawn, so as to put the pawl out of action, and a pin 61, connected to the lever 57, is simultaneously projected into a recess in the jaw 3 to prevent its movement. To facilitate the quadding of infrequent short lines, a pawl 63, which can be turned out of action, is mounted on the lever 57, so as to be engaged by a pin 64 on the first elevator, and to withdraw the plunger 55 after the casting. Specification 14582/90, [Class 100, Printing, Letterpress &c.], also is referred to.

Filed: 1919-08-16
Abstract: 158,589. Snarry, J. W., and Bullows, R. J. Aug. 16, 1919. Regulating; valve-gear.-In a two-stroke engine having a valve in the piston, for admitting the charge from a pre-compression chamber to the working cylinder, actuated by a cam which is adjustable angularly on the crank-pin whilst the engine is running, means are provided to permit of such adjustment during running in engines in which the crank-shaft is not stationarv. For this purpose, the cam a is fitted with a spur-wheel c which gears with a wheel d coaxial with the crank-shaft b<1>, and normally the shaft b<1>, the wheels d, c, the crank-pin and the cam rotate as one, but the position of the cam on the crank-pin may be varied by adjusting the wheel d about the crank-shaft by traversing a head d<3>, which has a clutch connection at d<2> with the spindle of the wheel, and carries pins d<5> engaging helical slots in the crank-shaft. The normal setting of the cam may be such as to open the valve at the end of the power stroke to admit the charge after an exhaust port has been uncovered. Adjustment of the cam throttles the new charge and reduces compression. The Provisional Specification states that the invention is applicable to engines of the type described in Specification 140,598.
