Title: Improvements in or relating to shimmy damper
IPC: B64C25/50
Filed: 1953-09-16
Abstract: 739,739. Aircraft undercarriages. HOUDAILLE-HERSHEY CORPORATION. Sept. 16, 1953 [Feb. 11, 1953], No. 25601/53. Class 4. [Also in Group XXXII] A shimmy damper installation for an aircraft undercarriage wherein the wheel assembly is subjected to damping over a limited range only of its castering movement and is disconnected from the damping mechanism over the remaining portion of its movement comprises a strut 14 non-rotatably attached to the aircraft and associated with a relatively movable cylinder 13 to which the wheel-mounting fork is attached. The strut 14 carries two freely rotatable collars 40, 41 the collar 40 being connected to the wheel-carrying fork by a scissors linkage 46 and the collar 41 having an integral arm 48 connected by a link 49 to a further arm 31 clamped to the spindle 30 of a rotary piston or vane type hydraulic damping assembly 15 secured to the strut 14. The arm 31 has a cranked extension 35 having an upwardly extending portion 35b which is engaged on opposite sides by the free ends of a coiled centering spring 36 surrounding the assembly 15, the free ends being in contact also with opposite faces of a fixed bar 25 secured to the mounting of the assembly 15. The collar 41 carries, offset from its centre, a spring-loaded plunger 55 adapted to register with a recess 57 in the collar 40 whereby the two collars may be connected to transmit castering movements of the wheel to the damper assembly 15. Such damping is required over a limited range only of the full castering movement and to enable the wheel to caster freely beyond such movement the plunger 55 is formed with a laterally projecting head having cam faces on its under surface adapted to engage with opposed cam faces 63 on members fast with the strut 14 to withdraw the pin 55 from the recess 57 and to allow it to rest on the upper face of the collar 40. The spring 36 restores the wheel and collar 41 to its mid-position after castering and the pin 55 engages automatically with the recess to re-render the damping mechanism operative. The assembly 15 may be used for steering the undercarriage.

Filed: 1933-09-18
Abstract: 418,044. Starting prime movers. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. Sept. 18, 1933, No. 25740. Convention date, Oct. 8, 1932. [Class 38 (iv).] In an engine starter in which a pinion 13 screws along a threaded sleeve 2 driven from the shaft 1 of the starting motor 23 through a friction clutch 3, means is provided for effecting a light clutching action between the shaft and the sleeve until the pinion is fully in mesh with teeth on the engine flywheel 14, and for effecting a heavier clutching action for starting only when the pinion is fully in mesh. A rod 26 carries at its rear end an iron core 30, lying within a magnet coil 32, and a contact bridge 31 adapted to cut out a resistance 45 in series with the field 43 of the motor 23. On closing the starter switch 44, the armature shaft 1 is driven at moderate speed and drives the sleeve 2 through the flange 10 and disc 7, so that the pinion 13 moves axially on the sleeve into engagement with the flywheel 14. When the pinion comes into full mesh with the flywheel teeth, the coil 32 is switched on by a spring contact 37 engaged by a flange on the pinion 13. The coil attracts the core 30 and moves the rod 26 and sleeve 2 to the left, causing the flange 10 to compress the clutch plates 5, 8 and the bridge member 31 to cut out the series coil 45, so that full torque is transmitted from the starting motor.

Title: Process and installation for the extraction and production of peat by mechanical dehydration of raw peat
IPC: C10G5/04
Filed: 1929-08-23
Abstract: 338,950. Evans, W. E., (Madruck, Ges. f³r Maschinelle Druckentwõsserung). Aug. 23, 1929. Peat. preparing.-In the preparation of dried peat for briquettes from raw peat, the raw peat is mixed with peat dust, preferably in such quantity that the weight of dry material in the dust exceeds that in the raw peat, the mixture being subsequently highly compressed, preferably by a hydraulic press, to extract water. So much dust is added as to bring the water content of the raw peat approximately to the same level as that of the dust, when the latter has absorbed moisture from the former. The compressed material is broken up, heatdried, aired, cooled, and sifted to produce dust for the preliminary mixing with the raw peat, and larger r material for making g briquettes. The large quantity of peat dust used provides many drainage channels, so that large quantities can be pressed in one operation, hydraulic presses, if employed, providing for ready regulation of the pressure whatever the nature of the raw peat employed. The early motion of the filter-press ram in compressing the mixture is performed rapidly under low water pressure and the final motion slowly under high pressure, the curve of this latter motion when plotted against time occupied preferably being of parabolic form. The material is advanced hydraulically by a bottomless carriage to lie upon the bottom ram 2 of the press, which ram has been raised to the top of the perforated cylinder 1. The ram 2 and an upper ram 6 are then lowered to lie at opposite ends of the cylinder. The ram 6 is held and the ram 2 raised, first under low pressure and then under high pressure to compress the material, which is finally raised so that it is thrust off the ram 2 into a receptacle by the carriage advancing with another charge. The compressed and disintegrated material is aerated to remove surplus moisture and then cooled.

Abstract: 303,542. Mahon, H. G. B. Oct. 4, 1927. Gauge glasses. -In a gauge glass, the water level is shown by the difference in brilliance between light condensed by the watercontaining part and the dispersed light, the source of illumination being so screened that the condensed and dispersed light are separated so that a receiving screen can be placed to receive either beam of light. The beam of light is not passed centrally through the gauge glass, but to one side of a diameter, to produce greater separation of the condensed and dispersed light. To obtain uniform illumination of the whole length of the gauge glass, the illuminant may be raised above the top of the gauge glass, or the same effect may be obtained by a horizontal reflector j, Fig. 3, which deflects the light from a lamp a through the upper part of the glass C' so that it may be clearly seen from a position below.

Refrigerating, solution processes for.-Apparatus for effecting continuous refrigeration by the absorption of heat in the process of solution of a salt such as ammonium nitrate in a solvent such as water, comprises a tank b in which the cold is produced, arranged for example in a small refrigerator a, a concentrator i and condenser o arranged outside the chamber, and a liquid circulating-pump f. The brine is circulated by the pump from the tank b through a pipe c, jacket d, pipe g and jacket h to outlet pipes h<2> discharging into the concentrator i. which is heated by suitable means k and is closed by a cover i<1> to prevent escape of steam. The concentrated.liquid flows up dip-pipes i<2> into a tubular member l having an extension l<2>, and falls on to a series of inclined trays l<3> arranged in staggered formation on the walls of the tube l. Owing to the cooling action of the brine in the jacket h the solid crystallizes out, the action being facilitated by stirrers n<2> on a shaft n<1> driven from the pump motor f<1>. Any crystals gathering on the trays ara detached by the stirrers or fa.1 off. The solid flows through the extension l<2> into a mixer m. The steam from the concentrator flows into an outer jacket o open at the top, and is condensed partly by the rising brine in the jacket h and partly by external air. The steam and condensate are passed through a coil o<2>, which may be cooled by a water jacket and then through a further coil o'' cooled by the brine in the jacket d, the cooled coudensate being- continuously discharged into the mixer. The mixer may have a screen m<1> at the bottom to retain solid salt to effect complete solution before it enters the brine tank.
