Title: Improvements in or relating to shock absorbers
IPC: B64C25/60
Filed: 1938-12-30
Abstract: 523,282. Hydro - pneumatic shock - absorbers. STEVENS, A. H. (Cleveland Pneumatic Tool Co.). Dec. 30, 1938, No. 37855. [Class 108 (iii)] A shock-absorber includes telescopic members 42, 43 and a partition 14<SP>B</SP> fixed in relation to one member 43 and provided with a passage 54 for metering flow of fluid between the members ; a cylinder 56 is mounted on the partition and is provided with a piston 61 or the like which is adapted to move under fluid pressure to cooperate with a port 58 in the side of the cylinder for metering the flow of fluid through the passage. In one form, the shock-absorber comprises telescopic tubes 42, 43, Fig. 1, guided by splines 27<SP>1</SP>, 28<SP>1</SP>. The diaphragm 14<SP>B</SP> is provided with orifices 53 and the opening 54 is regulated by a metering pin 62 attached to the piston 61 working in the cylinder 56. The upper end of the cylinder 56 may be closed except for a small aperture or be provided with a disc valve 59 opening inwards against springs, the disc being provided with a small aperture 60. The strut is filled with air and liquid and under a slight shock liquid flows through orifices 53 and piston 61 may rise slightly to permit some flow through the opening 54 and partially open ports 58. On rebound, liquid passes into cylinder 56 through port 57, the disc valve 59 being unseated. Piston 61 is thereby forced down to its lowermost position and the metering of the liquid takes place through orifices 53 to check rebound. On heavy impact piston 61 rises at a rate controlled by flow through aperture 60 and uncovers ports 58 so that the flow through the diaphragm takes place at a faster rate and in order that some of the impact is absorbed by the air in the upper end of the strut. When the impact is particularly heavy the piston 61 may rise sufficiently for the metering pin 62 to close the orifice 54 thereby retarding the flow. In a modification, the diaphragm 14D, Fig. 3, may be imperforate except for a conical valve 73 enclosed in a cylinder 71 provided with ports 72. The valve is provided with an orifice 75 and is loaded by a spring 76. On compression the liquid flows through orifice 75 and under heavier shocks valve 73 rises and liquid flows through ports 72. When valve 73 is lifted off its seat the effective area exposed to the pressure beneath the piston is increased and the closing of the valve by the spring 76 delayed. U.S.A. Specification 1,888,578 is referred to.

Title: Apparatus and method for coating articles in a fluidised bed of plastic material
Inventor: LAULAN JEAN MICHEL
IPC: B05D1/24
Filed: 1966-09-05
Abstract: 1,123,329. Coating articles by immersion in a fluidised bed of powder. RHONE-POULENC S.A. 5 Sept., 1966 [15 Sept., 1965], No. 39624/66. Heading B2L. Articles are coated in a vessel 4 which contains a bed of a powdered plastics material and to which gas is supplied such that at least two vertically adjacent powder containing zones of different density are produced of which at least the least-dense zone is fluidised, by supplying the articles one by one to the upper part of the more dense zone, raising an inclined grid 9 into contact with the article to cause the article to slide by gravity down the grid into the less dense fluidised zone, and removing the article from the fluidised zone. The more dense zone slows down the descent of the article and allows its lower surface to be coated while the remaining surfaces are mainly coated in the fluidised zone. To achieve the differing degrees of density in the two zones, a fluidisation gas entering at 5 passes through a porous plate 6 which is covered in part by a slidable shutter 7 such that the zone above the shutter 7 is substantially non-fluidised. Prior to coating the articles are heated in an electric furnace 1, and a pneumatic jack 10, which moves the grid 9, also causes actuation of the furnace shutter 2. The fluidiser is followed by a perforated slide 14, which allows any exces powder to run into recovery vessel 15 and leads onto a conveyor belt 16 which passes through an infra-red oven 17 and into a cooling vessel 18.
