Title: Improvements in and relating to the production of ammonium sulphate
IPC: C01C1/246
Filed: 1962-02-19
Abstract: (NH4)2SO4 and S are produced by reaction of a heated aqueous solution of ammonium sulphite and ammonium bisulphite at, e.g. 120-190 DEG C., in a vessel containing a number of perforated plates arranged to give streamlined non-turbulent flow without any back-flow. The solution may be preheated before its introduction into the reaction zone and is not heated further in this zone.  A preferred vessel is a vertical cylinder which may be operated with the solution flowing up or down the vessel. The plates may be grids, cones, truncated cones, cuspidal or spheroidal shaped or corrugated sheets.  The concave sections of the plates may be uppermost or downward whilst the conical plates have a summit angle of 120-180 degrees.  The plates are arranged transversely along the longitudinal axis of the vessel and may be supported upon a central axial support which may be demountable into small sections by means of screw-in connections. The perforations in the plates are of diameter 6 to 16 mm. and constitute 0.5 to 50% of the surface area of the plate whilst the plates are at 100 to 500 mm. intervals.  The plates have a gas between their periphery and the interior wall of the vessel or in between the neck of the plate and the axis.  In Fig. 1, the aqueous solution is pumped through preheater 2 into the vessel 3 which has thermometers <PICT:0982152/C1/1> 6 and 7, pressure gauge, safety valve and bursting disc 4a, 4b and 4c, respectively.  Part of the sulphur formed falls through the vessel 3 to reservoir 10 whilst the solution passes through 12 to decantation vessel 8 where the sulphur is separated and passed to reservoir 10 by pipe 13. The product solution is removed through expansion valve 9.

Title: An Improved Type of Airship.
Inventor: HUCK JOHN ROBERT
IPC: B64B1/00
Filed: 1916-05-04
Abstract: 105,274. Huck, J. R. May 4, 1916. Aerial machines with aerostats; aerostats; propelling; steering- balancing, a n d regulating altitude. - An airship is supported by an adjustable aerostat having a cork framework covered with sheet cork and strengthened wire and wire netting, and is driven by adjustable fans carried by the wheels of a car or of a cycle-like structure. The aerostat, which may be circular in cross-section but otherwise of the shape shown, comprises an inner compartmented shell of sheet cork supported by a cork framework strengthened with wire, and an outer spaced frame and shell of two or three layers of sheet cork, each layer having a covering of wire mesh. The aerostat is connected at its ends by cords which pass under the pulleys shown and around a large central pulley, which can be adjusted to tilt the aerostat longitudinally. Rubber-tyred wheels are carried in wide forks projecting fore and aft of the framework or car, and pairs of rectangular blades are pivotally mounted on the spokes, a spoke lying diagonally along each blade. The outer edges of the blades are connected by hooks to an auxiliary rim capable of sliding on the wheel rim and slotted to take the spoke heads. Movement of the auxiliary rim under the action of air currents thus causes simultaneous movement of the blades about their pivots. The rear wheel-fork is pivoted to move upwards or downwards 45 degrees each way and can also be turned over on its side. The wheels are adapted to have their upper and lower portions enclosed at will by pairs of shallow hoods of cork or wire mesh, as shown applied to the front wheel, those for enclosing the upper portion being fixed at right-angles to those for enclosing the lower portion, so that the pair not in use forms a laterally projecting plane on each side of the wheel. Both wheels are driven from a pulley 1 by belts comprising wire-bound ovoid cork links eyeleted and threaded on cords. Springs S in the rear chain permit movement of the rear wheel. The pulley 1 is driven forwards or backwards by pedals through the reversing-gear shown in Fig. 12. For forward driving, the pulley 1 is in engagement with projections on a sun-pinion carried by a sleeve I on a squared portion of the pedal shaft L. The sleeve I and a sleeve H sliding on a fixed spindle K are engaged by the forked ends of a lever G adapted to be moved by a lever F. When the lever F is operated, the sun-pinion is released from the pulley 1 and engages a pinion 4 on the sleeve H, the pinion 4 also engaging internal teeth within the rim of the pulley 1. A light motor may be used as an auxiliary in large machines.

Abstract: 683,669. Spring suspensions; shock absorbers. DAIMLER-BENZ AKT.-GES. March 16, 1951 [March 16, 1950], No. 6432/51. Classes 108 (ii) and 108 (iii). A vehicle springing arrangement comprises in combination with a main spring and one or more additional springs which becomes effective or become effective only after a certain deflection of the main spring, a damping device adapted for counteracting the return swing of the springing by wholly or partially suspending the restoring effect of one or more of the additional later-effective springs during the return swing. In the arrangement shown in Fig. 1 a spring 13 clamped at each end to a frame 10 is connected at its other end to a shock absorber 17, which end is normally spaced from a rubber cushion 14 secured to an axle 12. The shock-absorber 17 offers only slight resistance to upward movement of the spring 13, but heavily damps downward movement thereof. In another arrangement, Fig. 3, one end of a supplementary leaf spring 131, secured to an axle 12, is connected to a shock absorber 17<1> which is also secured to the axle. The spring 13<1> co-operates with rubber cushions 141, 141. An additional spring 18 becomes effective after full deflection of spring 13<1>. A shock absorber may be connected to both ends of the spring 13<1>. In another arrangement (Fig. 5, not shown), in which a coil spring is disposed between a swinging half axle and a vehicle frame, a supplementary coil spring is disposed within the main spring and a telescopic shock absorber is connected between the frame and half axle. The shock absorber, Fig. 6, comprises a piston 27 slidable in a cylinder 26, the piston including one or more passages 29, a non-return valve 30 and a damping orifice 32. A by-pass 31 in the cylinder 26 permits substantially restricted fluid flow from one side of the piston 27 to the other at a point in the downward stroke of the piston, corresponding substantially to the position of the supplementary spring at which the latter becomes ineffective. The invention is applicable to link quadrilateral suspensions and the damping device may be variable in operation and may be a friction damper.
