Title: Production of carbene derivatives
IPC: C07C17/266
Filed: 1961-12-08
Abstract: Hydrogen halide is produced as a by-product during the vapour phase reaction of a carbene (generated from a carbene precursor) and an acceptor substance in the vapour phase and in the absence of liquid base.  Carbene precursors are compounds of formula <FORM:0986060/C1/1> where X and Y are H, CN, or halogen, Z is halogen other than fluorine.  During the reaction the halide is split off in decreasing order of molecular weight, i.e. hydrogen iodide, bromide, chloride, cyanide.  In examples hydrogen chloride is obtained from chloroform and cyclohexene, or propylene.  Reference has been directed by the Comptroller to Specification 925,917.ALSO:Carbene derivatives are produced by contacting in the vapour phase a carbene and an acceptor substance (other than a carbene generator) in the absence of liquid base, the carbene having been generated from a carbene precursor.  The carbene may be generated in the presence of vapours of the acceptor substance or before contacting the acceptor. The carbene precursor is a compound of formula <FORM:0986060/C2/1> in which X is H1CH1 or halogen, Y is H1CH1 or halogen, Z is a halogen other than fluorine.  The carbene may be generated by heat along or by using a catalyst which may be oxides and phosphates of alkaline earth metals prepared by precipitation and on which have been deposited halides of metals of Group Ia, Ib, IIa, IIb and IIIa of the Mendeleer Periodic Table.  Acceptor substances include unsaturated hydrocarbons, ethers, esters, alcohols, nitriles and acids, the carbene reacting with the unsaturated linkage.  Specified reactions are between chloroform and benzene to produce chlorobenzene, chloroform and propylene to produce chloroprene, chloroform and cyclohexene to produce toluene.  Numerous examples of carbene precursors and acceptor substances are given.  Reference has been directed by the Comptroller to Specification 925,917.ALSO:Toluene is produced by heating chloroform with cyclohexene at 400 DEG  to 700 DEG  C. in the proportion of from 0.2 to 0.8 mols. cyclohexene and from 0.8 to 0.2 mols. of chloroform.  During the reaction the chloroform is decomposed into hydrogen chloride and dichlorocarbene which reacts with the cyclohexene.  Toluene is separated by fractional distillation.  Reference has been directed by the Comptroller to Specification 925,917.

Alternatively, the 5-cyano compound may be hydrogenated in the presence of hydrochloric acid to form the 5-hydroxymethyl compound directly.  Cyclobutylmethyl bromide is prepared by treating cyclobutane carboxylic acid with lithium aluminium hydride to form cyclobutylmethanol and treating this with phosphorus tribromide. Cyclopropylmethyl bromide is similarly prepared via cyclopropylmethanol.  4 - Amino - 5 - chloromethyl - 2 - cyclopropylmethyl-pyrimidine hydrochloride is prepared by reacting 4-amino-5-hydroxymethyl-2-cyclopropylmethyl-pyrimidine with thionyl chloride.

Title: Improvements in or relating to a Pressure Lubrication System for a Trunk Piston
Inventor: POPE JOSEPH ALBERT
IPC: F02B3/06
Filed: 1966-10-07
Abstract: 1,175,844. Lubricating. MIRRLEES NATIONAL Ltd. 18 Aug., 1967 [7 Oct., 1966], No. 44818/66. Heading F2A. [Also in Division F1] A trunk piston 10 for a reciprocating-piston I.C. engine comprises a gudgeon pin 12 fixed to the associated connecting-rod 13 and containing a pair of piston-and-cylinder units 18, 21 to effect intensification of the pressure of lubricating oil in a central distributing-groove 27 within an immovable bearing-bush 11 for the pin. The piston 21 in each of the units aforesaid is biased into abutment with a tappet 22 by a compression spring 24, which tappet has an oblique end-surface engaging with a cam 39 attached to a dished cap 14 that is fixed to the piston in alignment with the gudgeon pin. The tappets are substantially non-rotatable relative to the gudgeon pin so that owing to oscillation of the latter . about its longitudinal axis as the piston reciprocates the cams 39 effect reciprocation of the pistons and consequent displacement of oil within passages or duets 25 communicating with the innermost ends of the cylinders. 18, the latter being fixed by screw threads on a portion or head 19 thereof. The ducts 25 are charged with pressurized oil by way of a duct 13a in the connecting-rod and a passage 37 in an axially-movable valve-member 34 containing a non-return ball valve-member 38, which permits the pistons 21 to effect a pumping action that drives oil from the ducts 25 into the groove 27 through passages 26. The valve-member 34 is lodged in a chamber 28 and is biased upwardly by resilient dished-rings 35, the purpose of this member being to relieve excessive pressure in the ducts 25. The chamber 28 communicates with circumferentially - orientated grooves 31 at the ends of the bush 11 through passages 29, 30, which are thereby in direct communication with the duct 13a. Oil in spaces between the end caps 14 and the gudgeon pin is distributed to the outer surfaces of the piston through ducts 15, a cooling chamber or space 16 and outlets 17, high-pressure oil in the ducts 25 being prevented from leaking into said spaces by copper sealing-rings 20 adjacent shoulders on the outer parts of the cylinders 18. A proportion of the output of each of the units 18, 21 may be used to effect lubrication of other parts of the piston, e.g. the exterior surface.

Title: Liquid crystal display device with interdigital electrode
IPC: G02F1/133
Filed: 1974-10-23
Abstract: 1489893 Matrix displays TOKYO SHIBAURA ELECTRIC CO Ltd 23 Oct 1974 [31 Oct 1973] 45829/74 Heading G5C [Also in Division G2] A dynamic scattering liquid crystal display device comprises at least two interdigital electrode pairs occupying registered areas in two parallel spaced planes, the teeth of one pair being at an angle to those of the other pair, and A.C. voltages are applied to the electrodes so as to produce an electric field with a rotating component, increasing the scattering efficiency of the cell, and reducing the rise and decay times and the threshold voltage compared with that obtained with an oscillating A.C. field of the same amplitude and frequency. In a first embodiment, the two electrode pairs lie either side of the liquid crystal layer, or both lie to one side of the layer and are separated by a transparent dielectric. The teeth of one pair are at 90 degrees to those of the other pair and relative A.C. potentials (as shown in Fig. 3B, sinusoidal waves of equal amplitude and differing in phase by 90 degrees) A and C, and B and D are applied to the electrodes of respective pairs. The amount of scattering may be successively reduced by holding one electrode, and one electrode of each pair at the D.C. (earth) potential of all the electrodes, i.e. grey-scale modulation, but still lies above the prior art wherein A.C. potential differences in phase were applied between both electrode pairs. In a second embodiment, two interdigital electrode pairs spaced by a transparent dielectric lie to one side of the liquid crystal layer, a third pair being disposed on the other side of the layer, the teeth of each pair being at 60 degrees to those the other pairs. Relative A.C. voltages A and D, B and E, C and F, Fig. 11, are applied to the electrodes of respective pairs. A seven segment or X-Y matrix display may be formed of a number N of sets each of two electrode pairs in a common cell, Figs. 12 and 14 (not shown). One electrode of each pair is connected in common to the (N-1) like electrodes. Due to the reduced threshold voltage and rise time in the presence of the rotating electric field component, which is only present at the addressed point, cross-talk in the X-Y matrix with "half-voltage address" can be reduced by suitable choice of the addressing speed. Alternatively the known twofrequency or 1/3 voltage bias methods can be used.
