Abstract: Case 3-13360/ARL 306/+                    CANADA         PHOTOPOLYMERISATION PROCESS EMPLOYING COMPOUNDS         CONTAINING ACRYLOYL GROUPS AND MALEIMIDE GROUPS  SUMMARY      In a three stage process, a layer of a liquid composition containing a compound (A) having in the same molecule at least one (meth)acryloyl group and at least one 2,3-disubstituted maleimido group is exposed to actinic radiation so that the layer solidifies due to photopolymerisation of (A) through the (meth)acryloyl group(s), remaining, however, further photocrosslinkable.  When desired, the solidified layer is exposed, as through a negative, to a substantially greater amount of actinic radiation, the parts so further exposed becoming more highly photocrosslinked through the disubstituted maleimido group(s) and hence insoluble.  An image is produced which can be developed by means of suitable solvents.  Examples of (A) include N-(2-(acryloyloxy)ethyl)-2,3-dimethylmaleimide and N-(3-(methacryloyloxy)-2-hydroxypropyl)-2,3-dimethylmaleimide.

Abstract: ABSTRACT OF THE DISCLOSURE         An antilock braking system and associated method for a four wheel automotive vehicle having front left and right wheels and rear left and right wheels with a determined weight distribution of the vehicle on the front and rear wheels, each wheel having a respective brake cylinder adapted for applying braking pressure to the wheel in response to pressure fluid supplied from a master cylinder.  The supply of pressure fluid from the master cylinder to the brake cylinders during a braking operation is controlled in accordance with the weight distribution of the vehicle on the wheels to enable the front and rear wheels normally to undergo incipient wheel slip at substantially the same time.  A fluid pressure regulating unit relieves the fluid pressure transmitted to the respective brake cylinders of the four wheels of the vehicle all at the same time when one of the two front wheels rotates at a higher circumferential speed than the other front wheel and indicates incipient wheel slip.

Abstract: ABSTRACT OF THE DISCLOSURE           A process is described for the preparation of methyl tert-butyl ether and ethyl tert-butyl ether by the selective reaction of methanol and ethanol respectively with isobutylene contained in C4-hydrocarbon fractions, in particular those resulting from processes for the thermal or catalytic pyrolysis of suitable petroleum fractions.  The reaction is carried out in the liquid phase, under the influence of acid catalysts, at increased temperatures and pressures and with a molar ratio of the alcohol to the isobutylene equal to or approximately equal to the stoichiometric value. To the reaction medium are added inert aliphatic hydrocarbons which are liquid under the operating conditions in order to dilute the medium to a greater extent than the dilution given by the inert hydrocarbons contained in the C4-fraction of the feed.          For this purpose, in the most typical embodiment, the exhausted C4-fraction itself is recycled to the reaction medium.  By means of this dilution, the thermodynamic equilibrium conditions of the reaction system are favourably influenced, and improved conversions of the isobutylene to the useful reaction product are achieved.

Abstract: Abstract A method and apparatus for separating a medium into components having different particle masses by means of centrifugal force in free turbulence flow operated equipment, e.g. cyclones. The invention serves to reduce the friction resistance between a vortex and a chamber by removing part of a chamber wall or an entire chamber wall from between parallel vortexes. The supporting action of a chamber wall is compensated for by having parallel, oppositely rotating vortexes collide with each other at an angle of 0 to 90°. Turbulence separators can be built up into large systems in which parallel vortexes are disposed e.g. in circular configuration or in a regular square net. Having the vortexes collide with each other further acts to develop a separating power intensifying radial oscillating motion in vortexes.

The chase is also removably positioned on the support so that an entire chase can be readily separated from the apparatus, and a differ-ent chase with different printing heads substituted in the apparatus.  The chase is equipped with guides which cooper-ate with guides on the apparatus frame to insure automatic alignment of the chase as it is located in operating posi-tion, and the drive shafts carrying the printing heads are at the same time automatically engaged with drive means associated with the apparatus.  Locking mechanisms are pro-vided to secure the chase in position relative to the frame and the chase is also equipped with pins engageable with the apparatus frame and having the capability of adjusting print-ing head pressure on the material being printed.  The chase is also equipped with means for automatically shifting the heads between "On Impression" and "Off Impression" posi-tions in the course of a printing run.

Abstract: Abstract of the Disclosure This invention relates to a composition for developing latent electrostatic images by liquid development and a method of transferring the developed image to a carrier sheet over a gap.  The gap is formed by dielectric spacing particles disseminated through a dielectric carrier liquid, through which toner particles are also disseminated. The toner particles and the spacing particles bear the same surface charge so as to repel each other while in the de-veloping liquid.  Apparatus is provided, for use of the novel developing composition, which includes a metering means adapted to remove excess liquid from the surface of a developed image.  In order to induce the spacing particles to migrate toward the photoconductor, the metering means is biased to a potential greater than that of the non-image areas. This enables the spacing particles, which have a higher dielectric constant than the carrier liquid, to migrate toward the photoconductor.  The toner particles, however, will be attracted to the metering means from the background areas so as to maintain these clear of toner particles.  The method contemplates the steps of biasing the metering means with a potential of opposite polarity to the polarity of the toner particles and yet permitting the spacing particles to remain on the photoconductor to perform their spacing function at the gap transfer station.

The nickel layer is of high density,  tensile strength and ductility.   Before the application of the microcracked hard-chromium layer,  the previously-applied  nickel  layer  is  activated electrolytically in a sulphuric acid bath, in order to improve the adhesion of the hard-chromium layer to the nickel layer.

Abstract: DEVICE FOR LOWERING A PERSON OR A LOAD ON A ROPE                ABSTRACT     A device for lowering a person or a load on a rope which automatically arrests further movement of the person or load on the rope regardless of which direction the rope passes through the device, and which is capable of accommodating ropes of different diameters.  The device of this invention includes a friction cylinder disposed on a base plate, a friction body, and a pivotally mounted control lever.  The rope is wrapped around at least a portion of the circumference of the friction cylinder and also around the friction body, and the rope thereafter passes between a concave braking surface disposed on the friction body and one end of the control lever.  The end of the control lever is provided with two camming surfaces which are positioned on opposite sides of the axis of rotation of the lever.  Regardless of the direction of movement of the rope, friction between one of the camming surfaces and the rope causes the rope to be wedged between that camming surface and the concave braking surface on the friction body.  Free movement of the rope is permitted by manually positioning the lever in an intermediate position so that both camming surfaces are spaced from the concave braking surface.
