Title: Improvements in or relating to silencers and spark arresters for gas streams
IPC: F01N3/06
Filed: 1954-01-29
Abstract: 771,759. Silencers for gaseous currents. COOPER'S MECHANICAL JOINTS, Ltd. and STREETE, C. M. Dec. 16, 1954 [Jan. 29, 1954], No. 2800/54. Class 7 (2). [Also in Group X] A casing 1 is divided into at least two compartments 1c, 1d in series by one or more transverse baffles 4, inlet conduits 2, 9 of substantially smaller cross-sectional area than the casing leading into the compartment 1c and into the or each succeeding compartment 1d being closed at the discharge ends thereof except for peripheral outlets 7. An outlet 13 allows the escape of gases from the last of the series of compartments. The gases issue from the outlets 7 with a rotary motion and circulate within the associated compartment, the arrangement being such that the gases do not readily lose their angular momentum before leaving a compartment and so cannot easily pass back into the conduit from which they are discharged. As shown, the compartment 1d is about one third greater in volume than that of the compartment 1c, and the baffle 4 is formed with a series of peripheral flanges 14 separated by narrow gaps and is secured to the casing by two diametrically opposed flanges so as to prevent the casing resonating within a predetermined frequency range ; the remaining flanges bear resiliently on the wall of the casing. The inner end of the inlet conduit 2, entering the casing near the bottom thereof, lies close to the baffle 4 and is closed by a cap 5 ; pressed-out louvres 8, Fig. 4, form a peripheral series of slots 7 which cause the gases to emerge from the conduit in substantially tangential directions. The gases pass from the compartment 1c into the compartment 1d via the conduit 9 secured in a central flanged opening of the baffle 4 and constructed in a manner similar to that of the conduit 2 ; the conduit is secured to the baffle by brackets 15 and by a bracket 11 to the wall of the casing. Anti-resonance holes 2a, 9a are provided in the conduits. The conduits 2, 9 may be staggered with respect to each other as shown ; alternatively, the conduit 9 may be axially aligned with the outlet pipe 13, or the conduits and the pipe 13 may all be disposed on the central axis of the casing. The device may be mounted vertically, ash contained in the gases being centrifuged out to fall on to the baffle or lower surface of the casing removed through cleaning doors.

Abstract: 489,383. Automatic couplings for vehicles. STRAUSSLER, N., and ALVISSTRAUSSLER, Ltd. Feb. 2, 1937, No. 3101. [Class 103 (v)] In a semi-trailer coupling a single central ramp A mounted on the tractor for co-operation with a roller Q on the trailer is provided with an indentation a<1> adapted to receive a reduced or waisted portion of the roller, which is locked therein by means of a pair of independent spring-controlled hooks D pivoted on a transverse shaft E on the tractor and engaging the roller spindle G. When the tractor is backed towards the trailer to effect a coupling, the spindle G, on contacting with the hooks D, forces them back against the effort of springs F ; finally, the roller Q drops into the indentation a<1>, and the hooks D spring back and engage over the spindle G to prevent the latter from rising. Uncoupling is brought about by a pull exerted on a rod Z which is connected to a compensator arm Y linked to the hooks D. The coupling is preferably associated with braking means for the trailer, such means, as shown, comprising a brake operating rod X, bell-crank W having an extension W<1>, plunger T, bell-crank U and brake-rod V. When the brakes have been applied, they are maintained in this condition by a toothed pawl T<1> engaging the plunger T and actuated by a spring-pressed lever T<2> coacting with the extension W<1>. The brakes are also adapted to be applied during an uncoupling operation by the pull on the rod Z after the hooks D have been released, lostmotion links X<1>, Y<1> being provided to permit independent operation of the rods X, Z. In the act of coupling the tractor and trailer the bell-crank W is engaged either by the spindle G or roller Q and presses back the lever T<2> so as to release the brakes.

Abstract: 560,565. Selenium rectifiers and lightsensitive cells. STANDARD TELEPHONES & CABLES, Ltd. Feb. 26,1943, No. 3165. Convention date, April 13,1942. Drawings to Specification. [Class 40 (iii)] [Also in Group XXXVI] A selenium coated electrode for rectifiers or light sensitive cells is manufactured by heating a base plate having an adherent coating of selenium to a temperature between 80 C. and 120 C. for a short time and then applying pressure to the selenium coating while the temperature is raised to a point slightly below the melting point of selenium. This temperature may be between 160 C. and 218 C., and the pressure may be between 240 and 750 pounds per square inch. The times of the two treatments will vary somewhat according to the temperatures and pressures used. The initial treatment should be long enough to allow a sufficient number of nuclei to form, for example 5 minutes at a temperature of 100 C. without pressure. The final treatment may be in some cases only a matter of seconds. The whole treatment is completed in less than one hour. Specification 509,432 is referred to.
