Title: Improvements in connection with the brake gear of winding engines, hoists and the like
IPC: B66D5/26
Filed: 1926-09-30
Abstract: 284,3,71. English Electric Co., Ltd., and Dixon, J. D. Sept. 30, 1926. Brakes for winding-apparatus.-In biake gear for winding engines including a cataract cylinder and a brake engine cylinder arranged in line and having the two pistons connected with the same piston rod, and in which when the brake is applied under normal service conditions by hand control, manipulation of the valve of the brake engine cylinder is used as the means of controlling the extent and rapidity of braking, but when emergency braking takes place, this valve is opened fully and the rapidity of action is determined solely by the cataract cylinder, the degree of control exerted by the cataract cylinder is determined by a valve which is set normally at a position where it permits the degree of control to be relatively weak, and which is influenced by the emergency brake gear in such a way that as this gear is brought into action the valve may be moved into a position which corresponds to relatively strong control by the cylinder to provide for emergency braking conditions which permit of gradual retardation, an additional gear being provided for this valve which is controlled automatically bv means dependent upon the conditions of winding, or by hand, in such a way that it can cancel or prevent the movement of the valve into the relatively strong controlling position due to the operation of the emergency brake gear. The ends of the cataract cylinder 1 are connected by pipes 3, 4 provided with valves 5, 6 respectively. The valve 5 is hand-actuated and is set to such a position that when the valve 6 is closed the maximum control required is exerted. The valve 6 is actuated by a rod 7 which is pivoted to the weighted arm 19 of a catch lever 9 loosely mounted on a shaft 10. This shaft is biassed by a weight 15 and has a second catch lever 20 keyed to it. A third catch lever 12 having two catches 13, 14 and an actuating arm 16 is keyed to a shaft 17 which is biassed by a weight 18. Pins on the actuating arms of the catch levers project into slots in links 21, 22 which are connected by a. rod 23 to a hand lever 24. The arm 19 is engaged by a catch 25 on an arm 26 which is controlled either by a hand lever 30 or a cam 27 driven by the winding drum, or the cages, or the depth indicator. The shaft 10 is connected to a link mechanism which operates the valve of the brake engine and the emergency control switches. The shaft 17 also is controlled by mechanism of known kind which operates on failure of current to the winding motor, or failure of the air pressure, the occurrence of an overwind, or in the event of the speed of the drum exceeding a predetermined maximum.

Title: An improved method of and apparatus for condensing vapours, in particular the exhaust steam of locomotives, particularly turbine locomotives
IPC: F28B1/06
Filed: 1937-09-17
Abstract: <PICT:0485972/III/1> The greater part of the exhaust steam of a turbine locomotive is condensed by a moist cooler and the cooling-air thereof, moistened as a result of the condensation, is subjected to the heat in the remainder of the exhaust whereby it is rendered invisible.  The engine exhaust steam passes by pipes 2, 3 through a condenser 1 and the cooling-water thereof is led to a perforated pipe 7 and passes down a cooling hurdle 9 on to an inclined wall 10 leading to a trough 11 connected by pipe 4 to the circulating pump 6. Air is drawn through the hurdle by a fan 14 and passes through a condenser 13 heated by a portion of the exhaust steam, which may comprise the exhaust of the engine driving the auxiliaries.  The condensate passes to the exhaust inlet 2 or the condensate discharge 3 of the condenser 1.  The cooling-air is thus rendered invisible. Modifications are described comprising arrangements of two or more hurdles.  These may be directly associated with the condensers. Instead of the cooling-air passing through the condenser 13, it may be heated by admixture with additional hot air passed therethrough. In a further modification of the arrangement shown, a trickler condenser is used in lieu of condenser 1.  In this construction, the cooling-water from the holes 7 trickle over air-cooled steam tubes.

Title: Improvements in appliances for playing games
IPC: A63F9/00
Filed: 1920-09-02
Abstract: 172,695. Chester, F. R. Sept. 2, 1920. Race games. mechanical.-Relates to apparatus for playing a game at pleasure resorts, exhibition grounds, and the like of the type described in Specification 172,388 in which hollow fragile objects are charged with fluid under pressure so as to inflate or burst them and consists more particularly in the provision of a reservoir of compressed fluid and means for supplying the objects first with fluid at a low pressure and finally at a high pressure, so as to inflate and burst them. As shown, the reservoir 27, Fig. 1, containing compressed air is connected to each of the balloons 22 through high and low pressure pipes 25 and 35 respectively. The air supplied through the low-pressure pipe is controlled by a valve 130, a diametrical aperture 46, Fig. 3 in a manually-operated shaft 12, and a valve 121 which is controlled by an electromagnet 124. The air supplied through the high-pressure pipes is controlled by a valve 30 and an electromagnet 51. In using the apparatus, the attendant closes the battery switch 62 so as to energize the electromagnet 134 and open the valve 130, and the players stand in front of the table and turn the hand-wheels so that air passes into the cylinder 36 and through the aperture 42, Fig. 6, to the balloons. The weighted piston-rod 38 rises and falls in the cylinder owing to fluctuations of the air pressure and makes and breaks the contact 96, thus energizing and de-energizing the electromagnet 87 which is mounted upon a pivoted arm. The armature of the electromagnet 87 is provided with a pawl 85 engaging a rack 70 which is raised gradually until it contacts with a flexible member 71 and energizes the electromagnet 51 so as to open the valve 30 and admit air at bursting pressure from the reservoir into the balloon. The rack is prevented from falling when the electromagnet 87 is de-energized by a pawl 102. If the pressure within the cylinder 36 becomes excessive, the piston-rod engages the contact 110 and energizes the electromagnets 91 and 124 so as to release the pawl from the rack, which falls to its lowermost position, and open the valve 121 respectively. The winner is the player who succeeds first in bursting his balloon.

Abstract: 338,588. Standard Telephones & Cables, Ltd., and Blumlein, A. D. Aug. 21, 1929. Inductances, measuring; inductances. - An alternating- current bridge is provided with a fixed external inductance coupled through a magnetic core to inductances in at least two of its arms, the resistance of the bridge being kept constant while the mutual inductance is varied by current fed to the external inductance. A variable inductance comprises a number of relatively fixed inductances conductively connected and fed from a common source of alternating current, the ratio of current to potential on different members being varied by means of a shunted network across the inductance through which the current is varied. In one arrangement, Fig. 1, the coils 1, 4 and 5-8 form the primary and secondary windings of a toroidal inductance, current being fed from the source S through a variable resistance R to the secondary winding 5-8. The variable resistance R may be calibrated in inductance values. The measuring &c. instrument Z is connected in the diagonal A, C and when an inductance is being measured it is located at X in the arm A, D. In another arrangement, the coupled coils of the variable mutual inductance are both external to the bridge, and such an arrangement is employed in shielded bridges without affecting the shielding. The coil carrying the varying currents can be connected across a network such as that described in Specification 202,284, [Class 40 (iii), Telegraphs, Electric].
