Title: Imitation Sheepskin Fabrics
Inventor: ROBINSON DEREK GILBERT
IPC: A41H41/00
Filed: 1967-10-10
Abstract: 1,198,819. Knitting; finishing fabrics. IMPERIAL CHEMICAL INDUSTRIES Ltd. 7 Oct., 1968 [10 Oct., 1967], No. 43187/67. Headings D1K and D1S. An imitation lamb or sheepskin fabric comprises a pile made from melt spun quenched drawn synthetic aromatic polyester fibres which have a denier of four or more and a resilient helical crimp. The pile may be formed by weaving or knitting in tufts of helically crimped polyethylene terephthalate fibres with a tenacity of 2 to 6 grams per denier, an extension to break of 10 to 60%, an initial modulus of 20 to 40 grams per denier, a crimp index of 15 to 70%, a crimp level of 2 to 13 crimps per straight inch, a mean rate of change of instantaneous modulus between 5% and 10% per extension, of 90 to 160 grams per denier and a denier of 4 to 18 and an assemtry of refractive index of not less than 1.10<SP>-3</SP> measured across the width of the fibre. The fabric is given a finishing treatment after it has been sheared to the required length to give it a pebble like appearance. This is achieved by conventional textile operations such as hot air tumbling, winch processing or even stentering with a suitable down draft of hot air in order to give the required degree of interlocking or coalescing of the fibres into pebble like clumps. If desired the fabric may be subjected to a further treatment such as polishing the pile fibres with high gloss rapidly rotating heated cylinders. This has the effect of reducing the size of the clumps and the width of the cleavage.

Title: Production of titanium trichloride
IPC: C01G23/02
Filed: 1963-11-01
Abstract: Titanium trichloride is produced by reducing titanium tetrachloride at an elevated temperature with silicon or boron and condensing the titanium trichloride formed.  The reaction is preferably carried out between 700 DEG  and 1100 DEG  C. and the condensation of the titanium trichloride takes place at a temperature above the boiling points of the titanium tetrachloride and of the volatile chlorides of boron and silicon formed in the reaction, and a preferred condensation temperature is between 150 DEG  and 300 DEG  C. Alternatively, the condensation zone may be held at 30 DEG  C. so that TiCl3 forms as a solid phase dispersed in the other liquid halides, from which the solid TiCl3 phase may be obtained by filtration in an atmosphere of inert gas.

(C8H5)2O; SnCl4.2(C5H5)N; SnCl4.2N(C4H9)3; SnCl4.2(C2H5)3N; and SnBr4(CH3)3N.  If desired, the aryl aluminium compound may be prepared in situ by heating aluminium dust, powder or grit which has been activated by small amounts of a halogen, hydrogen halide, a metal halide or an organometallic compound, with an aryl halide such as chlorobenzene, bromobenzene, 4-bromotoluene, 3-chloro-4-methyltoluene, 2-chlorotoluene, 4-chlorocumene, a -chloronaphthalene or 4-chlorodiphenyl.  This process may be carried out in an inert solvent such as benzene, toluene, xylenes, cyclohexane or n-heptane.  In the reaction with the tin compound aluminium halide is produced and this may be removed by complexing with an aromatic or aliphatic ether or thioether, a tertiary amine or an alkali metal or alkaline earth metal halide, thus allowing the desired aryl tin to be recovered by distillation or, in some cases, fractional crystallisation.

Abstract: 1498716 Corona charging apparatus XEROX CORP 29 Oct 1975 [16 Jan 1975] 44653/75 Heading H1X A corona discharge device is operated by applying to the corona electrode wire 12 a first constant D.C. potential and applying to the conductive shield 11 partially surrounding the wire 12 a second D.C. potential of the same polarity as the first upon which is superimposed a distinctly pulsed potential variation. As shown, in use in electrophotographic apparatus for charging a photoconductive surface 22 carried on a conductive substrate 21 held at a fixed potential, e.g. earth, the the negative-going pulses from source 27 superimposed on positive D.C. bias 26 increase the potential difference and hence the field between the shield 11 and wire 12 for the efficient generation of ions at the wire 12. Upon removal of the pulse from source 27 from the shield, the generated ions are preferentially attracted to the photoconductive surface 22 rather than to the shield. In an example given the pulse width is of 2-10 microseconds with a repetition rate of 200-5000 Hz. In an alternative embodiment the batteries are replaced by a high voltage D.C. supply and the pulses are supplied through a transformer from a pulse generator, Fig. 2 (not shown).
