Abstract: ABSTRACT OF THE DISCLOSURE         In a process for producing an ethylene polymer by the slurry-type polymerization of ethylene or ethylene and other olefins by using a catalyst system comprising a high-activity supported-type Ziegler catalyst component (hereinafter referred to as solid catalyst component) and an organometallic compound component in the presence of hydrogen as molecular weight regulator in two or more reaction zones connected in series and kept full with the liquid phase to exclude the gas phase, the improvement which comprises using a solid catalyst component of long-lasting high-activity and limiting the average amount of polymer formation in each reaction zone within a specific range.  According to the said process, it is possible to vary the average molecular weight, molecular weight distribution, and density of the polymer as desired and to produce economically on a commercial scale a polymer having desirable physical properties and processability.

Abstract: ABSTRACT               CATALYTIC COMBUSTION ENGINES            A catalytic combustion engine, each cylinder of which has a pre-combustion chamber (30) communicating through an inclined transfer cylinder (10) to produce swirl around the chamber, and has a pair of spaced parallel. or nearly-parallel catalytic screen elements (37, 41 or 55), e.g. gazes, mounted adjacent to both the mouth of the transfer passage (13) and the fuel injector nozzle (21), so as to be clear of the circumferential swirl path of the gas circulating in the chamber.  The minimum spacing between the two catalytic screens should exceed the width of the mouth of the transfer passage (13).  The injector (21) injects a fuel spray between the two catalytic screens which preferably just brushes each screen and impinges on a heater plug (24).  The compression ratio may be much lower than that for a conventional Diesel engine, for example down to 12:1.

Abstract: ABSTRACT      The invention is concerned to control the combustion conditions of a burner 1 supplied with a mixture of pulverized fuel and air,  By use of a vortex amplifier 10 in the supply pipe 3, the supply of fuel is interrupted so that the flame is consequently first too lean and then too rich. The temperature of the burner flame is monitored by a photodiode device 6a and an indication is pro-duced of the delay between the operation of the vortex amplifier 10 and the flame temperature pass-ing through that indicating that the flame conditions are optimum,  The length of the delay will indicate whether, and to what extent, the flame before the operation of the vortex amplifier was too lean or too rich,  Adjacent burners can be controlled by operating the vortex amplifiers associated with each at different regular frequencies.

Abstract: ABSTRACT            The apparatus contains a target exposed to a beam of accelerated electrons and an electron absorber positioned behind the target.  The acceleration energy of the electron accelerator is monitored by monitoring the traveling range of the electrons in the absorber.  For this pur-pose the electron absorber is made up of several in-sulated absorber portions which are arranged one behind another.  Each of these portions is electrically con-nected to a separate input of a processing system.            The monitoring apparatus is especially well suited for application in electron accelerators in medical radiation therapy, such as linear accelerators.

Abstract: ABSTRACT           An automatic apparatus which transports filter cigarettes from a tipping machine to a packing machine has a first transporting unit which directly couples the output of the tipping machine with the magazine of the packing machine, and a second transporting unit which receives the surplus of filter cigarettes from a diverting device of the first transporting unit when the output of the tipping machine exceeds the requirements of the packing machine and delivers the removed surplus back to the first transporting unit when the requirements of the packing machine exceed the output of the tipping machine.  The second transporting unit employs a tray filler which receives cigarettes from the diverting device, a first conveying section which transports filled trays away from the tray filler, a tray evacuator which converts the contents of successive filled trays into a stream of cigarettes and turns the cigarettes through 180° so that the orientation of cigarettes in the stream deviates from the orientation of cigarettes in the first transporting unit, and a second conveying section which delivers the stream to a junction of the first transporting unit. In order to restore the original orientation of diverted cigarettes, the first or second conveying section embodies a loop-shaped inverting device which changes the orientation of cigarettes in filled trays or the orientation of cigarettes in the stream by 180° so that the orientation of cigarettes which reenter the first transporting unit is the same as that of non-diverted cigarettes.

Abstract: TITLE LASER-SURFACE COUPLER                   INVENTORS Paolo G. Cielo Serge Dallaire ABSTRACT OF THE DISCLOSURE The laser-surface coupler is used to uniformly irradiate a well defined surface area with a laser beam.  The coupler includes a lower masking section and an upper section to form a cavity.  The mask-ing section has inner surfaces which are highly reflective and lustrous, and an aperture to define the surface area to be irradiated.  The upper section has an opening to receive the laser beam into the cavity, and a highly reflective and diffuse inner surface to reflect and diffuse any radiation reflected to it from the irradiated surface.  The coupler recycles any reflected radiation from the laser beam increasing the absorption coefficient and the irradiated surface is precisely defined by the masking section without loss of energy.
