Inventor: MENNESSON BERNARD RENE
IPC: F16D43/18
Filed: 1959-03-26
Abstract: 859,651. Friction clutches. SOC. D'APPAREILS DE CONTROLE ET D'EQUIPEMENT DES MOTEURS S.A.C.E.M. March 26, 1959 [April 3, 1958], No. 10673/59. Class 80 (2). A centrifugal friction clutch for motorassisted pedal cycles wherein spring-retracted centrifugal masses 14, 15 pivoted between plates 19, 20 fast with the driving shaft 6, acts on levers 16, 17 carrying friction segments 18 which are moved radially by the masses 14, 15 at a predetermined speed into engagement with a drum 9 fast with the output shaft 4, has arms 16a, 17a fast with the levers 16, 17 which are engaged by the masses 14, 15 when the latter are retracted by springs 23 to engage the clutch when the engine is stopped, thus permitting push starting. The clearance between the arms 16a, 17a and the levers 16, 17 is greater than the width of the masses, thus permitting the masses to occupy an intermediate position when the engine is idling, with the clutch disengaged. The levers 16,17 may be arranged, as shown, so that there is a wedging between the drum 9 and friction segment 18 during push starting and the arms 16a, 17a may be weighted (Figs. 5 and 6, not shown) to facilitate disengagement during idling. Apertures 13 in the casing 5 permit the circulation of air.

Abstract: 853,472. Aerials. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 8, 1957 [April 7, 1956], No. 10675/56. Class 40(7). An aerial system comprises a gapped loop conductor 1, 2, effectively one wavelength long at the frequency of operation with the feeder 5 connected across the gapped ends 3, 4. In the construction shown the loop is circular and a conductive support tube 7 extends from the midpoint of the loop diametrically across to the gap where it is attached to the end 3 along with the outer conductor of the coaxial feeder 5. The support tube 7 is attached centrally to a further support 8. Arrangements may be made to use a balanced feeder if desired. A director and/or reflector or a plurality of such may be used with the aerial. These may comprise closed loops 9, 10, in phases parallel to the aerial and spaced one-fifth of a wavelength thereform as shown in Fig. 2. The reflector circumference exceeds that of the aerial by about 5% and the director circumference is about 10% less. Reflectors and directors are also provided with diametrical support tubes and the further support rod 8 may run axially through all the elements. Two gapped loop aerials of the kind described may be arranged in parallel in a common plane; the gapped ends of the two being co-incident and connected to a common feeder Fig. 6 (not shown). The aerial may also be extended by adding loops in series, a second loop giving a figure 8 formation. The extension may be taken beyond two loops and Fig. 8 shows an arrangement in which two pairs of loops in series are connected in parallel at the feed point 12. A loop aerial according to the invention may be provided with series capacity elements inserted therein so that the physical diameter may be increased and the polar diagram improved. Linear or sheet reflectors and directors may be used instead of the type described with reference to Fig. 2.

Title: Improvements in or relating to pneumatic brakes for tramways, light railways and thelike
IPC: B60T15/04
Filed: 1921-04-12
Abstract: 161,951. Seguin, E. April 19, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Fluid-pressure. - The operating and distribution valves of pneumatic brakes for railway vehicles and the like are provided with pressed leather pistons instead of slide- or liftvalves. Fig. 1 shows the operating valve in lap position. To charge the system, the piston B is raised by the handle D<1> to admit air from the main reservoir connected at f to the trainpipe connected at f<1>, by the passages G, G<1>. Upon releasing the handle it and the piston B are returned to the position shown bv the main reservoir pressure acting on the piston B the downward movement of which is limited by the stop C. To apply the brakes the handle is depressed sufficiently against the action of a spring E to permit air from the train-pipe to escape by passages G<1>, G<2>. The distribution valve is shown in the running and release position in Fig. 2 in which air from the train-pipe feeds through the passage g, groove g<7> and passages g<1>, g<2> to the auxiliary reservoir and the brake cylinder is open to exhaust by passages H, g<3>, g<5>. When the train-pipe pressure is reduced to apply the brakes, the piston f<2> descends until it contacts with the washer I and compresses the spring h<1>. In this position the piston f<4> cuts off the passage g<3> from the exhaust passage g<5> and the piston f<5> is below the passage g<4> so that air flows from the auxiliary reservoir to the brake cylinder by this passage and the passage g<1>. When the auxiliary reservoir pressure has equalized with the reduced train-pipe pressure the pistons are returned to the extent of the stroke of the rod h in which position the pistons f<4>, f<5> respectively cut off the supply and exhaust passages of the brake cylinder so that a graduated application can be obtained. The arrangement of the pistons f<3>, f<4> f' ensures the balance of the apparatus in all cases.

Title: Improvements in or relating to gasifiers
Inventor: MASTERMAN STANDISH
IPC: C10J3/08
Filed: 1962-03-21
Abstract: A slagging gasifier, having a burner within a sleeve 27 for maintaining slag flow through the outlet 21, comprises a cylindrical body 1 surmounted by a charging dome 2.  The upper part of the body 1 has a metal clad refractory lining 8, a charge directing sleeve 60 and a gas off-take 4.  The combustion chamber of the gasifier has a refractory coated inner shell 6 spaced from the body 1 to leave a water space 9, which is closed at the bottom by a plate 17 connecting a tube 16 depending from the bottom plate 10 of the hearth with the body 1.  Cooling coils 29, 28, 31, 32 in the refractory burner sleeve 27, and in the lining of the combustion chamber have inlet pipes extending through a chamber 33 in the part of the body 1 below the hearth.  Cooling coils 28 in the refractory hearth discharge into the interior of the tube 16, the wall cooling coils 31, 32 discharge into lower part of the crater jacket between the tube 16 and body 1, and cooling water from the tuyere jackets is discharged into the tuyere insertion boxes 12.  Pipes 44 extending to the top of the water jacket 9 discharge the cooling water through connections 46 first below the tuyere level.  The lower part of the body 1 containing a slag receptacle 48 and a frit draw-off pipe 52, 52a is supplied with water through a pipe 51 discharging downwardly into the container 48 to agitate the frit.  A water level indicator 53 <PICT:0977122/C4-C5/1> is connected between the level of the pipe outlet box 33 and the tube 16, the upper tube 55 passing into the tube 16 through the housing 56 of a sight glass for observing the flow of slag. The outlet pipes 46 from the water jacket 9 lead into the bottom of a tube 57 having an outlet 59 to the water filled bottom part of the body 1.  The tube 57 forms a stem supporting the slag receptacle 48, from which large lumps of slag may be withdrawn through a lock hopper (not shown).  The lower part of the gasifier may be purged through a pipe 66, and a sampling probe 62 may be inserted through the charging dome 2, which may have a radioactive detector to regulate or indicate the necessity of charging.  The water pressure in the cooling tubes and water jackets is maintained at a level suitable to the operating pressure of the gasifier.  Hot gases from the burner not only maintain freedom of slag flow through the tap hole 21, but also the freedom of slag flow in the race way below the tuyeres, and prevents solid fuel passing out of the tap hole 21.  The burner may be used to start the gasifier from cold, and frit withdrawn from the container 48 may be recirculated to maintain a suitable slag flow from the gasifier. A pyrometer (not shown) may be located at the outer end of a quartz rod extending through a tuyere and acting as a waveguide.
