Abstract: 997,848. Shock absorbers. STABILUS, INDUSTRIE - UND HANDELSGESELLSCHAFT G.m.b.H. Jan. 15, 1964 [Jan 15, 1963], No. 1799/64. Heading F2S. A fluid pressure damping device in which the filling medium 4 is under high pressure comprises a cylinder 1, a piston 2 and a piston - rod 3 extending through a first wall of the cylinder. An end part 5 freely passes through a second wall of the cylinder and is provided with an annular flange 6 within the cylinder. An elastic sealing ring 9 is placed between the flange 6 and a corresponding annular surface of the second wall such that, in its uncompressed state, a gap is left between the cylinder and the outer surface of the sealing ring for filling the damping element with fluid. When the pressure is cut off externally of the damping device the internal pressure acts on the flange to compress the sealing ring against the annular surface of the cylinder. The construction may be incorporated in hydraulic, pneumatic or hydro-pneumatic damping devices. The filling may be an inert gas, e.g. nitrogen, at from 50 to 200 atmospheres.

IPC: H01J17/04
Filed: 1962-01-18
Abstract: 1,025,381. Pulse generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 18, 1963 [Jan. 18, 1962], No. 1921/62. Heading H3P. A pulse generator of the kind in which a pulse forming network (PFN) is periodically charged and then discharged through a load to generate a pulse, is provided with a protective arrangement to reduce the voltage to which the PFN is charged under fault conditions. As shown, the PFN is charged from the EHT supply unit via inductor H and thyratron V 1  and discharged via a magnetron load when the thyratron V 2  is triggered. Breakdown of the magnetron load results in the voltage across the PFN reversing, hence valve D 1  becomes conductive producing a voltage pulse which is integrated and used to vary the instants at which thyratron V1 is triggered so as to reduce the time period during which it is conductive and hence reduce the voltage to which the PFN is charged. A further integrator having a long time constant is provided to reduce the output from the EHT unit if the fault persists.

Patent GB-1066651-A (GB)
Title: Oxides
Inventor: CLEAVER DENIS
IPC: C01F7/302
Filed: 1965-01-18
Abstract: A process for the production of oxides (e.g. TiO2) by oxidizing a halide (e.g. TiCl4) in the vapour phase with an oxygenating gas in a reaction zone having a porous wall comprises heating an inert gas or one or both of the reactants at least to the temperature of the oxidation by means of a radio-frequency induced plasma, maintaining the temperature of the reaction zone at least in part by means of such heated gas and effecting the oxidation while transpiring a further gas or vaporizable liquid through the porous wall into the reaction zone whereby the deposition of solid products on the wall is inhibited.  The further gas may be inert, e.g. N2, or the same as the halogen of the halide reactant.  The pore size of the wall, which may be of fritted silica, should be such as to give a pressure drop across the wall sufficient for even distribution of the transpired gas.  The plasma may be produced by a single layer solenoid or spiral pancake induction coil of metal (e.g. Cu tube cooled by water) which may be shielded if the transpiral gas is corrosive (e.g. Cl2) by enclosing in a coil of hollow silica ware.  In a preferred embodiment the reactor is double-walled, the induction coil being wound round the inner porous wall, with a reverse turn at each end to contain the plasma magnetically to a zone through which the heating gas or reactant must pass.

Title: Improvements relating to drive chains
IPC: F16G13/04
Filed: 1929-01-22
Abstract: 305,167. Morse Chain Co., (Assignees of Morse, F. L.). Feb. 1, 1928, [Convention date]. Driving-chains with separate joint pins.-The effective centre of articulation of the joints is arranged to be positively moved, during articulation of the chain, transversely to the line of pull, to cause the leading link of the free run first to dip and then to rise relatively to the last link engaged by a tooth of the sprocket wheel. In the construction shown in Fig. 2, each joint pin consists of three mebers 3, 4, 5, the members 3. 4 being respectively keyed in adjacent links while the member 5 floats between them. When the chain is straight the member 5 engages at 7 with one link so that it is constrained to move with the member 4 during the first half of an articulation, after which it is engaged at 8, Fig. 4, by the other link and is constrained to move with the member 3 on the seating of the member 4 for the remainder of the articulation. A modification is described (Figs. 12 to 14, not shown), wherein the bearing surfaces of the member 5 are concave instead of convex. In the construction shown in Fig. 5, a rib 13 on the member 5a engages in a wider groove 12 in the member 4a, which thus first moves relatively to the member 5<a> and then moves with it on the member 3<a>. In a modification (Fig. 6, not shown), interengaging ribs and grooves are formed at both sides of the floating member, both surfaces of which are convex. In the construction shown in Fig. 7, a cam 15 on the member 4d engages with one end of the member 3<d> and first depresses this and then allows it to rise again during an articulation. In the construction shown in Fig. 9, the relative movements of the parts of the pintle are controlled by an external cam, e.g. a cam-slot 16 in one link engaged with a pin 17 in the other link. A similar control of a one-part pin joint is shown in Fig. 11. sufficient vertical play in the joint being allowed to enable the cam 16f and pin 17<f> to act.

Title: Improvements in connection with filters
IPC: B01D25/00
Filed: 1923-01-25
Abstract: 209,947. Candy, F. P. Jan. 25, 1923. Filters with loose filtering-materials. - To ensure that a filter shall start work slowly after cleansing the inlet for unfiltered liquid or the outlet for the filtered liquid is controlled by a valve, actuated by the slow filling or emptying of a bucket or the rise or fall of a float in a tank other than the filter tank. As shown in Fig. 1, a butterfly valve 2 on the supply pipe for unfiltered liquid is normally kept open by the weight of a float 6, connected by a chain 7 to a quadrant 3 on the spindle of the valve and adapted to overcome a weight 9 which is also connected to the quadrant. When the valve 4 on the supply pipe is closed for cleansing, valves 11, 16 connected thereto by rods 17, 14 are respectively opened and closed. Water then enters the tank 5 through the valve 11 and a ball cock 10, the float 6 rises, and the weight 9 closes the valve 2. When cleansing is finished and the valve 4 opened, the valve 11 is closed and the valve 16 opened. As the tank 5 is emptied through a timing-valve 18, the float falls and slowly opens the valve 2. Fig. 2 shows an arrangement in which a double-beat valve 2 in the filtered liquid outlet is slowly opened as a float 6 rises when a tank 5 is filled through a timing-cock 18. The rod 17 is in this case connected to the wash-water outlet valve. The valve 2, Fig. 3, is opened by a weight 9 as a bucket 5<A> empties. The weight is attached to a cam 3 on the spindle of the valve in such a manner that the leverage due to the weight decreases as the bucket rises. The bucket is filled from a flush tank 24. According to the Provisional Specification the supply of water to, or the emptying of water from, the bucket or tank may be automatically effected by the operation that opens the filtered water outlet, and a floating arm may be used for emptying the bucket or tank.
