Title: Overhead service unit
IPC: B66F11/04
Filed: 1975-02-28
Abstract: 1487889 Propelling elevators HUGH J BAKER & CO 28 Feb 1975 [12 April 1974] 8551/75 Heading B8L An overhead service unit for connection to a tractor vehicle 10, comprises a base 12 having a first frame secured thereto and extending upwardly therefrom, a pair of second frames 40, 50 slidably interconnected to each other and to the first frame, and a service platform 60 movably mounted on the second frame 50, the unit being extensible and retractable by a pair of hydraulic rams 90, 96 and 91, 92 and associated chains 150, 165 and 175, the rams moving in opposite directions to each other to cause movement of the frames and platform in a single direction. The ram 90, 96 has its cylinder 90 pinned at 95 to the base 12 and with the platform 60 in the lowered position, the pistonrod 96 of the ram is fully extended and a pair of sprockets 125 on a cross axle carried by the rod 96 engage a pair of chains 150 which extend from fixtures 152 at the top of the first frame, over sprockets 134 at the top of the first frame, around sprockets 142 at the bottom of one second frame 40, around sprockets 148 at the top of the other second frame 50 and are secured at their ends to the platform 60. Upon downward retraction of the ram rod 96, the platform is raised by rolling along guides on the said other second frame 50, the axle carrying the sprockets 125 being guided along rails 110 on the first frame. A similarly guided axle carrying a pair of sprockets 160 at the top end of the piston-rod 92 of the pin mounted ram 91, 92, engages a pair of chains 165 extending between fixtures 167 on the base 12 and fixtures 168 at the bottom of the said one second frame 40, whereby extension of the ram 91, 92 causes elevation of the frame 40 relative to the first fixed frame. A third pair of chains 175 extend from fixtures 185, 186 on the first fixed frame, over sprockets 178 at the top of the second frame 40 and are secured at 188 to the bottom of the second frame 50, whereby as the second frame 40 is elevated by the ram 91, 92 the chains 175 cause the frame 50 to elevate relative to the frame 40. The hydraulic pressure necessary to motivate the ram 90, 96 is less than that required for the ram 91, 92 whereby upon supply of fluid, the ram 90, 96 is first retracted elevating the platform 60 relative to the frame 50, whereafter the ram 91, 92 is extended causing elevation of the frame 40 relative to the fixed frame and consequential simultaneous elevation of the frame 50 relative the frame 40. When selected, the fluid is returned from the rams to reservoir simultaneously so that the platform and frames all lower together. Wheels 34 are mounted laterally of the unit, and are associated with stabilizing feet engageable with the ground.

Patent GB-803376-A (GB)
Title: Stabilization of acrylonitrile
IPC: B04B11/06
Filed: 1957-03-20
Abstract: Stabilized acrylonitrile is produced by incorporating therein from about 1 to 1000 parts per million of a tetra-alkyl thiuram mono-sulphide of the formula <FORM:0803376/IV (b)/1> wherein R is an alkyl radical containing 1 to 4 carbon atoms. Ordinarily the stabilizer will be used in amounts of 1 to 300, preferably 5 to 150 parts per million.  Tetramethyl thiuram monosulphide is preferred, in concentrations from 5 to 50 parts per million.  Tetra-ethyl thiuram monosulphide and diethyl dimethyl thiuram monosulphide have a similar stabilizing effect. The stabilizers may be used to protect acrylonitrile from polymerization during distillation, during processing and under storage conditions for long periods of time, even in the presence of oxygen and with use of high temperatures of storage.  The small amounts of stabilizer have no appreciable effect on the polymerization rate in emulsion systems with normal alkali metal persulphate, hydrogen peroxide, organic peroxide or hydroperoxide catalyst at low or high temperatures.  Examples demonstrate the stabilizing effect of the tetraalkyl thiuram monosulphides in an accelerated ageing test employing acrylonitrile containing acetaldehyde charged to an oxygen bomb with oxygen under 100 pounds pressure at 100 DEG  C.  Comparison with the use of hydroquinone, t-butyl catechol, hydroquinone monobenzyl ether, and phenyl b -naphthylamine is also made.
