Filed: 1928-09-18
Abstract: 326,812. Neumann, E. Sept. 18, 1928. Alcohols, aldehydes, and ketones. - Higher alcohols, accompanied by the corresponding aldehydes and ketones, are obtained by passing the vapours of lower alcohols, alone or in admixture, at atmospheric pressure and a temperature not exceeding 350‹ C. over catalysts comprising a mixture of a hydrogenating or dehydrogenating component with a dehydrating component. Starting from single alcohols it is possible to obtain alcohols having twice the number of carbon atoms, whilst a mixture of different alcohols gives rise to products whose number of carbon atoms equals that of the starting materials. Hydrogenating or dehydrogenating catalysts mentioned are silver, copper, cobalt, iron and nickel; as dehydrating catalysts the oxides of aluminium, thorium, iron, chromium, tungsten, titanium and beryllium are specified, and dehydrating salts are referred to. The aldehydes and ketones arising from the debydrogenation of the original alcohols, together with the unaltered portion of the original alcohols, may be reintroduced into the process, or circulated through a second system containing the same catalyst. Examples are given of the preparation of (1) butyl alcohol from ethyl alcohol using a mixture of copper and alumina or thoria; acetaldehyde and butyl aldehyde are also obtained; (2) 2-methylpentanol-1 and the corresponding aldehyde from propyl alcohol over a mixture of silver and alumina; (3) methylisobutylcarbinol and the corresponding ketone from isopropyl alcohol over a mixture of copper, nickel and thoria; (4) methylpropylcarbinol and methylisobutylcarbinol, together with the corresponding ketones and some butyl aldehyde, acetaldehyde and acetone, from a mixture of ethyl alcohol and isopropyl alcohol over copper and kaolin.

Title: Improvements in or relating to stabilising devices for vehicle suspension arrangements
IPC: B60G17/015
Filed: 1936-10-05
Abstract: 465,563. Vehicle spring-suspensions; vehicle shock-absorbers. LEGGOTT, R. R. Oct. 5, 1936, No. 26930. [Classes 108 (ii) and 108 (iii)] In stabilizing devices for vehicle suspensions of the kind in which hydraulic or like shockabsorbers on opposite sides of the vehicle are hydraulically interconnected so as to operate against tendency of the vehicle to tilt but arranged to operate independently so long as the chassis remains parallel, a pendulum, inertia device, &c. is operably connected to a pair of valves in such a manner that one valve only at a time is moved to its closed position to vary the cross-sectional area of the crossconnection between the shock-absorbers. Shock-absorbers 10, 12 are mounted on the longitudinal 11, 13 respectively of the frame and each absorber comprises two cylinders 19, 20 with pistons 21, 22 operated by a rocking arm 14 connected to the shaft 15 on which is mounted the arm 16 connected to the axle. The shaft 15 is provided with cams adapted to operate a valve 29 to restrict the openings 25, 26 between the two cylinders 19, 20. The cylinders 19, 20 of the shock-absorber on one side of the vehicle are connected to the opposite cylinders 20,19 of the absorber on the other side of the vehicle by conduits 30 having narrow ducts 31. Arranged centrally on a transverse member 36 is a pendulum 32 pivoted at 33 in a casing 34 and connected by wire cores 37 to valves displaceable across the passages 26 of the shock-absorbers. These valves comprise parts 39, 41 with a reduced part 40 between them. In operation if the vehicle tends to tilt the pendulum 32 will operate the cores 37 so that on one side the part 39 will completely close the connection 25, 26 between the cylinders 19, 20 while on the other side the part 41 will restrict the connection 25, 26. Assuming the descent of piston 21 and rise of piston 22 in one shock-absorber 10 in which the valve 39 closes the intercommunication then as piston 21 in absorber 20 descends fluid is forced through the conduits 30 to cylinder 20 of absorber 12 but as the piston 22 of this cylinder is descending it opposes the entry of fluid and an increased volume of fluid is forced through the restricted passages 25, 26 of absorber 12 with the result that a greater resistance is given to the movements of the pistons and thus a stabilizing effect is exerted by the shockabsorbers on the vehicle frame. If however, no tilting takes place and the wheel on one side only meets an obstruction then the shockabsorber on that side only is operated the fluid passing from one cylinder to the other through the passages 25, 26. Instead of a pendulum an inertia mass may be employed.

Abstract: 774,136. Detecting leaks by means of radioactivity. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 23, 1955 [Sept. 23, 1954], No. 27489/54. Class 40 (3). [Also in Group XL (c)] To detect leaks in pipe lines a radio active solution is made up in a container attached to the inlet valve by a tube and is allowed to run into the liquid already flowing in the pipe. A squce-gee go-devil is then inserted in the pipe at a point up stream from the radio-active solution and travels along the pipe-line under the action of the flowing liquid. After about half an hour a second squee-gee go-devil is inserted in the line. The second go-devil carries or is attached to a radio-activity detector and recorder and so records radio active liquid which has leaked to the outside of the pipe and has not been flushed away. If the recorder runs at a constant speed the positions of the peaks corresponding to the leaking points may be correlated with the length of the pipe but radioactive markers may be arranged along the pipe to mark the record. Fig. 3 shows the construction of the detector and recorder which is attached to the second squee-gee go-devil by a swivel bolt 16 and which comprises a stainless steel housing 10 with domed ends 11, 15. Inside the casing mounted on shock absorbers 12 is a framework comprising three aluminium plates 2a, 2b, 2c supported on screwed rods 3. Between plates 2b and 2c are four Geiger tubes 4 and wire recorder 5 of known type. Between plates 2a and 2b is a transistor pulse lengthening circuit 6 (see Group XL (c)) and batteries 7, 8, 9.
