Filed: 1941-08-11
Abstract: 551,888. Accumulator batteries. CHLORIDE ELECTRICAL STORAGE CO., Ltd., and GRAY, R. Aug. 11, 1941, No. 10201. [Class 53] In an accumulator cell of the type having an anti-spill device comprising a chamber a wholly or mainly external to the cell, with a depending tubular extension c terminating at the plates, and with a tube f extending down into the chamber from the vent aperture e, the space within the cell above the plates is reduced to an extent which causes a surplus of electrolyte to pass from the cell into the chamber when the cell is inverted, the chamber and the length of the tube f being so proportioned as to prevent any of this surplus flowing into the tube f and out of the vent e. The reduction of the space above the plates in the cell results in a cell of less weight and of less electrical resistance owing to the shorter cell pillars. In the form shown the chamber a screws into the top of the cell and is provided with strengthening ribs h.. The tube f is closed at the bottom, where it has a lateral aperture g; it may contain baffles or a system of tubes or chambers. In a modification the chamber is formed integrally with the top of the cell and the tube f depends from a cap screwed into the top.

Title: Process for the preparation of complex synthetic esters
IPC: C07C69/34
Filed: 1958-03-31
Abstract: Synthetic ester lubricating oils of general formula <FORM:0818136/IV (b)/1> wherein R1 and R5 are C5-12 alkyl radicals, R2 and R4 are hydrocarbon radicals of a C4-12 dicarboxylic acid, R3 is a C2-20 glycol or polyglycol radical, x is 1 to 6 and the esters preferably contain from 20 to about 150 carbon atoms are prepared by heating a C2-20 glycol or polyglycol and a C5-12 alkanol with a diester of a C1-3 alkanol and a C4-12 dicarboxylic acid and removing the alcohol formed during the reaction.  An inert entraining agent is generally used, e.g. a hydrocarbon such as heptane, benzene or toluol.  After the low-boiling alcohol and the bulk of the entraining agent have been removed by distillation the product may be filtered or washed to remove catalyst, if used, and then stripped at about 175-200 DEG  C. under about 1-10 mm. Hg pressure, preferably with a nitrogen purge. A catalyst is preferably used, e.g. an alkaline esterification catalyst such as sodium methylate, metallic sodium, sodium-potassium alloy, K2CO3, lime, zinc oxide, or basic ion exchange resins. The C1-3 alkyl diester may be derived from aliphatic, alicyclic or alkylene aromatic acids.  Specified are dimethyl sebacate, diethyl adipate, diisopropyl azelate, diethyl norcamphorate, diethyl pinate, diethyl phenylene diacetate, diethyl methylglutarate, diethyl methyladipate and diethyl isosebacate.  The C5-12 alkanol may be straight or branched, e.g. oxo alcohols.  The glycol may be ethylene glycol or its homologues containing up to 20 carbon atoms and polyglycols such as polyethylene or polypropylene glycols.  An apparatus for effecting the reaction continuously is illustrated (not shown), it being stated that the molar ratio of the higher alcohol to the diester should be about 2 : 1 while the molar ratio of the diester to the glycol will usually be about 2 : 1, depending on the desired chain length in the product.  Examples describe the batchwise preparation of (1) a complex ester in which n is 1 from tetraethylene glycol, diethyl sebacate and 2-ethylhexanol and (2) a complex ester from a polyethylene glycol (m.wt. 200), diethyl norcamphorate and oxo decyl alcohol.

Abstract: 795,803. Ion trapping in cathode ray tube. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 28, 1955 [April 9, 1954], No. 10439/54. Class 39(1). An ion trap gun comprises an electrode 7, Fig. 1 with an eccentric aperture arranged between the first and second anodes 4, 5, the arrangement being such that the electrostatic fields between 4, 7 and 5, 7 have transverse components to deflect the beam twice in the same direction, the electrons subsequently being deflected back by means of a magnetic field. By keeping the electrostatic ion trap deflections small it is stated that distortion of the beam cross section can be minimized. The potential of electrode 7 must be less than that of second anode 5 ; it is stated that the potentials of 4, 7 can be equal in which case they can be joined by a tubular member or formed as an integral structure, Fig. 2 (not shown). The beam outlet end of second anode 5 may or may not have a transverse wall 6. The ion trap magnetic field is produced by a permanent magnet held on the tube neck by a spring clip in the correct angular and axial position and magnetic focusing is achieved by an annular permanent magnet or electromagnet. Since a single ion trap magnet cannot centre the beam on the tube axis if the gun and tube axis coincide, the gun axis may be tilted with respect to the tube axis. The second anode 5 need not be the final anode but can form the first electrode of a two electrode or unipotential electrostatic lens ; in this case electrode 5 has a transverse wall between its ends to prevent negative ions or secondary electrons from reaching the lens field.
