Title: Improvements in and relating to fish tails or like devices for the exhaust pipes of internal combustion engines
IPC: F01N13/20
Filed: 1925-09-18
Abstract: 259,017. King, R. O. Sept. 18, 1925. Exhaust-silencers.-A fishtail silencer comprises stamped or cast metal casings which are secured together by flanges 6, and form a passage having a converging top and. bottom 18, 19 and diverging sides 12 leading to a parallel-sided port 15; the passage is lined with asbestos sheets which are secured at their two ends only by plates 20, 21, 26. The shape of the casing enables a rectangular sheet of asbestos to extend from one seam 14 to the other. The silencer is secured to the exhaust pipe A by a nut 31 and a washer 32 having an extension 32<1>, slotted to accommodate the flanges 29; a nut 17, pinned to the exhaust pipe, serves as an abutment. Throughout the length of the silencer the crosssectional area inside the lining should be slightly less than the port area of any one cylinder discharging into the pipe A. According to a modification a number of the silencers may be connected together in tandem, and the Provisional Specification describes the use, in this arrangement, of asbestos strips continuous throughout the length of the series.

Patent GB-226625-A (GB)
Title: Improvements in or relating to brake mechanisms for winding engines or the like
IPC: B66B15/00
Filed: 1923-09-29
Abstract: 226,625. General Electric Co., Ltd., and Woollatt, G. S. Sept. 29, 1923. Regulating and control-transmitting gear for winding and paying-out apparatus.-Cornprises a brake mechanism for winding engines in which the emergency brake mechanism always comes into action slowly so long as the cage is more than a predetermined distance from the end of the run, no matter whether the braking is initiated by the operation of the emergency brake lever, by the overwinding mechanism, or by the failure of electric current or air supply, but which allows a rapid application of the brakes near the end of the run and in the circumstances applies a supplementary braking force in addition to the usual brake weights. Fig. 1 shows a brake cylinder 1 and a cataract cylinder 2, the brakes being applied by weights 6 and normally held off by pressure fluid acting on the under side of the piston 4. The normal or slow application of the brakes is initiated by moving the rods 28 downwards through the medium of the brake lever 24 which closes the fluid-pressure supply-valve 25 and opens an exhaust valve 31 communicating with the under side of the piston. The rod 28 is moved downwards also by the failure of the electric current allowing a solenoid core 39 to drop or by the failure of the compressed air supply allowing the weighted lever 41 to fall. The falling of the lever 41 also operates a switch 38 to cut off the current. When the emergency brake lever 45 is operated it closes an air valve 49 and opens the cylinder 44 to exhaust, thereby allowing the weighted arm 42 to apply the brake and cut off the current as before. This movement also actuates the 3-armed lever 52. This normally has no effect, but when the cage is less than a predetermined distance from the end of its run, a lever 55 registers with a recess on a cam 60 geared to the drum and allows the emergency brake lever 45 to be pulled over to its full extent, thus moving lever 52 sufficiently to cause interaction with the lever 35, thereby moving the lever 28 downwards to an additional extent, to re-open the valve 25 and close the exhaust valve 31. At the same time, the additional movement of the lever 45 operates through the links 63, 70 to release a weighted arm which is linked to the rod 17. The movement of the rod 17 reverses the distributing valve to admit steam above the piston 4 to supply the additional braking pressure. The overwinding mechanism acts on the weighted arm through the rod 69. In some cases only one brake lever is used, and in this instance the cam mechanism may be arranged to allow the brake lever to have an additional length of stroke when near the end of the run, in order to get the quickaction and supplementary braking effect. Specification 15139/07 is referred to.

Title: Improvements in or relating to methods of and apparatus for taking or projecting motion pictures
IPC: G03B41/08
Filed: 1928-08-23
Abstract: 296,669. Leventhal, J. F. Sept. 3, 1927, [Convention date]. Kinematograph apparatus.-Optical compensation for film movement in a continuous-feed apparatus is effected by rotating a plano-parallel refracting member or members about an axis inclined thereto, and by directing the light beam through it at such an angle that the displacement of the beam in the direction of feed is constant for each degree of rotation over a limited range.. As shown, the compensation comprises four refracting members 29 mounted on a shaft 23 carrying sprocket teeth 33. Light from a source 46 passes through a gate aperture 41, and is reflected by a, prism 44 through one of the members 29 to a prism 32 by which it is twice reflected to pass through a second member 29 to a projection lens 47 and the screen. Rotation of the shaft 23 feeds the film 34 downwards through the gate, round a sprocket 43, and thence round the shaft 23 to a take-up reel. The lateral displacement of the image produced by one of the members 29 is neutralized by the displacement produced by the other. Formulae for determining the proper inclinations of the members 29 and of the light paths through them, together with calculated values, are set out in the Specification. Modifications in which the light beam passes twice through one member 29 only, and in which the beam passes through two parallel members, are described in the Specification, the beam in each modification being reflected three times between the two passages.

Abstract: 584,056. Helico-centrifugal superchargers. MEISSER. C. Dec. 8, 1944, No. 24598. Convention date. Jan. 26. Drawings to Specification. [Classes 110 (i) and 110 (iii)] [Also in Group XXVII] A helico-centrifugal compressor driven by an exhaust gas turbine is used to supercharge a two-stroke I.C. engine. The helical blading of the impeller makes an angle with the tangent at the periphery of the impeller whose cosine is greater than the relative velocity of the air divided by twice the peripheral velocity of the impeller. The quantity of air drawn in by the compressor during one compression stroke and one expansion stroke of the I.C. engine amounts to at least twice the swept volume of the combustion cylinders and to not more than that volume in its compressed state at the compressor delivery. The exhaust gas turbine may be geared mechanically, hydraulically, pneumatically or electrically with the I.C. engine. Or, the turbine may be free and provided with an electric or other motor for starting and arranged to recover any excess power developed by the turbine. When the I.C. engine is used as a producer of power gas, two or more stages of helico-centrifugal compressors may be used. Such an I.C. engine may be of the free-piston type.
