Title: Improvements in or relating to shock absorbers
IPC: F16F9/512
Filed: 1961-06-09
Abstract: 983,394. Shock absorbers; seals. DES ETABLISSEMENT REPUSSEAU S.A. June 9, 1961 [June 9, 1960; April 13, 1961], No. 20951/61. Headings F2B and F2S. [Also in Division B7] A railway vehicle buffer, Figs. 1 and 2 (see Division B7), comprises a telescopic plunger B which when pushed inwardly under load compresses an hydraulic shock absorber unit E in parallel with rubber/ metal springs in Fig. 1, and a metal spring in Fig. 2. The unit E, Figs. 3, 4, comprises an oil-filled cylinder a, and a partly filled piston c provided with a head having an orifice j 1  which may be closed or throttled by a slidable stem j which on no load is pressed into the Fig. 4 position by springs 8 and u. In operation, as the buffing load increases the slider j is forced back against spring s until the gap x is closed. In this position, Fig. 7 (not shown), the orifice j 1  is closed by the head j 3  of the slider and oil can no longer pass from the space a 1  through the orifice and ducts q 1 , and pipe m to the reservoir c 1 . Increased load then causes the slider head j 3  to be pressed even further back to compress the heavier spring u, in which position, Fig. 8 (not shown), the slider head is clear of the other side of the orifice and oil can once again pass from a 1  to c 1 . The reservoir c 1  is vented to atmosphere through a passage i in the piston base and a pipe n which reaches above the oil in c 1  so that on recoil the oil returns from c 1  to a 1 . The seals f and g are subjected only to low pressures, as the piston when telescoping draws oil from c 1  at low pressure into the space behind its head. Oil forced past the seals is collected by a cup v, Fig. 9 (not shown), and returned to c 1 , or is collected in a bellows h and forced back into the reservoir during the next compression via tube n. The resilient low-pressure ring seals f of trapezoidal section are complemented by one or more of the seals g, Fig. 5, which are of rubber and are fixed by screws to the cylinder a. The seals g have thick lip portions which bear tightly on the piston c, and are retained against longitudinal displacement by a member p.

Patent GB-866446-A (GB)
Title: Improvements in or relating to estratriene derivatives
IPC: C07J75/00
Filed: 1959-06-18
Abstract: The invention comprises compounds of the general formula: <FORM:0866446/IV (b)/1> wherein X is halogen and Z is a carbonyl or hydroxymethylene radical or an alkanoyloxymethylene radical containing not more than 8 carbon atoms, and 16b ,17b -oxido-1,3,5(10)-estratriene. The compounds of the above general formula, where Z represents the carbonyl radical and X represents chlorine, bromine or iodine are prepared by treating a 1,3,5(10),16-estratetraen-17-ol-alkonoate with the required halogen in an inert solvent such as carbon tetrachloride, or with the required halogenating agent such as N-bromo- or N-iodo-succinimide. The corresponding 16-fluoro compounds are prepared by treating the 16-iodo compounds prepared as above with silver fluoride.  The compounds of the above general formula in which Z represents a hydroxymethylene radical are prepared by treating the corresponding 17-ones with a reducing agent such as lithium aluminium hydride or sodium borohydride.  Subsequent esterification forms the compounds in which Z represents the alkanoyloxymethylene radical.  The processes outlined above form a mixture of the 16a and 16b -isomers in which usually one isomer predominates and which may be separated by crystallisation. 16b -Iodo (and chloro)-1,3,5 (10)-estratriene-17-one may also be prepared by treating the corresponding 16a -iodo (and chloro) compounds with a lithium halide.  Detailed examples are given.  1,3,5(10),16-Estratetraen-17-ol acetate is prepared by reacting 1,3,5(10)-estratrien-17-one with isopropenyl acetate.

Title: Aircraft surface controls
IPC: B64C13/00
Filed: 1939-07-20
Abstract: 536,053. Aircraft controls. DOUGLAS AIRCRAFT CO. July 20, 1939, No. 21135. Convention date, March 28. [Class 135] A fluid-pressure servomotor with moving seat follow-up for actuating an aircraft control surface exerts a force which is always a multiple of that exerted by the pilot so that the feel of the control is retained. The ratio of the forces exerted may be varied. A fluid-pressure servomotor 17 is floatingly suspended between a lever 72, fixed to the torque tube 73 of the control surface, and a lever 76 pivoted to a fixed part 77 of the aircraft. Cables 83, 84 from the pilot's control actuate a lever 82, pivoted about the tube 73, a slot 88 being formed in the lever to engage a pin 89 on the lever 72. Connected to another pin, mounted on the lever 82 and normally co-axial with the pin 89 is a linkage 86 for actuating the pilot valve 19 of the servomotor. The lower end of the lever 82 is connected by a link 80 to the upper end of the lever 76, the piston rod of the servomotor being connected to a nut 75 which can be traversed along the lever 76 by a screw actuated by a motor 78. Movement of the lever 82 by the pilot actuates the valve 19 to cause the main piston to effect movement of the control surface in the same direction and cause the valve seat to follow up the valve, but since the reaction comes upon the lever 76 a proportion of the force exerted is transmitted to the pilot's control through the link 80. This proportion may be varied by altering the position of the nut. If the pivot 74 of the piston rod is brought into coincidence with the pivot of the lever 76 the reaction on the pilot's control is reduced to zero. Pressure fluid is supplied from a pump 11 delivering to a pressure chamber 58 containing air and oil separated by a diaphragm, and is led to the pilot valve through a pipe 16. Exhaust ports 26, 28, Fig. 2, lead to a common pipe 43 in which is a snubber cylinder 90 to restrict the flow back to a reservoir 15 and thus minimize the effects of gusts. The valve 19 is further controlled by a dash-pot comprising a piston 49 supplied on both sides with pressure fluid through pipes 52, 53 connected by a restricted passage 54, check valves 61, 62 being provided in the pipes 52, 53. Check valves 47, 59, 60, and a pressure-relief valve 46 also are provided in the system. The snubber cylinder 90, Fig. 3, contains a spring-loaded piston 98 having a restricted hole 99 so that under flow conditions the piston rises to cover to a certain extent ports 94 in a liner in the cylinder. Under extreme pressure resulting from wind gusts the ports are completely closed and the flow can only continue through small holes 104. Reference has been directed by the Comptroller to Specifications 131,354, 157,049, [both in Class 135], 185,850 and 265,631, [both in Class 69 (ii)].
