Abstract: ABSTRACT       The invention relates to a scanning device for reading and/or writing using a laser beam. A drum (243) includes a rotatable shaft (102) carrying optical elements (120) which are moved rotationally and translationally to cause a laser beam to scan sheet material lying around the surface of a cylinder coaxial with the shaft. A sheet to be scanned is placed on a flexible transport (150) while flat and then the transport is fed into the drum until a surface of the transport is in intimate contact with a location wall (243) of the drum. A bed (191) supports the flat transport outside the drum and there is a support (211,212) for supporting a transport above the bed together with positioning means (200) for the bed and support either for driving a transport on the bed into the drum or for driving a transport in the drum onto the support. The shaft (102) is rotatable in a housing (101) on air journal bearings (100) and end thrusts are balanced by air thrust bearings defined between a wall (125) of a reaction air turbine for driving the shaft, and a wall (124) of a porous plate through which air for the bearing is supplied through a controllable restriction (1232,1233).

Abstract: ABSTRACT OF THE DISCLOSURE         A mechanical gear changing device in a gear change box for motor vehicles, for engaging and disengaging positive drive clutches, with selector rails of rectangular cross-section running parallel with the gear-box shaft and each associated with a channel in the basic gearbox, the selector rails being arranged as a set and for example at an angle of 45° to the centre of the gear-box shaft, and being mounted in the gear-box housing.  The selector rails are provided with recess in which drivers, with rounded contact surfaces, are engaged by gear change levers mounted in the gear-box housing and/or gear change fingers arranged, for example, upon a selector shaft, or are secured to selector forks with selector rails.  All of the selector rails (2,3,4), of similar cross-section, are mounted directly and jointly in the gear-box housing at least at two locations and are adapted to pivot through 90° in order to co-operate with the selector fingers(91,92,93) arranged approx-imately vertically or horizontally.  The common centre of rotation of the selector rail is arranged in such a manner that the same gear change levers or selector forks are actuated by the associated selector rails and that the respective gear change levers and/or selector forks associated with the channels remain unchanged as regards position and shape.  The selector rails are preferably guided in circular bearing bushes (8,80) securable to the housing, each also carrying a locking plate which is specially shaped and is provided with an opening and, in the case of a group transmission, a blocking plate (65), co-operating with the selector rails and passing partly through the recesses.  The locking plate is actuated positively by a selector rail provided with notches (23,33,43) in an end recess (24,34,44) when it is shifted to an operative position.  The other two selector rails are locked by radial displacement or pivoting.  The locking device requires only this one locking plate, whereas the other parts are already present in the cir-cuit and may be easily adapted.  Under the action of a spring (99), blocking plate (65) presses a nose(68)at all times against a control cam(96)on selector rail 95 for the group transmission and blocks the selector rails (2,3,4) of the basic gear-box during a gear change in the group transmission when the said nose engages in indentation(97)in control cam (96).

Abstract: IMPROVED IMAGING SYSTEM                            ABSTRACT Means are provided for preventing image diffusion  : in images formed by imagewise exposure of a microencapsulated photosensitive material to actinic radiation, followed by a color forming reaction between a chromogenic material and a developer.  A curing agent for the photosensitive composition, such as an organic peroxide, is microencapsulated separately from the photosensitive material and included in the coating.  When the capsules are ruptured, the released curing agent reacts with the photosensitive material and thereby stabilizes the formed color so that its quality will not deteriorate over time.

Abstract: : PROCESS FOR THE DECOMPOSITION AND DECONTAMINATION OF ORGANIC SUBSTANCES AND HALOGENATED TOXIC MATE RIALS" A method for the decomposition of an halogenated organic compound is described which comprises reac ting the compound with a reagent which consists of a) at least one member which is a polyethyleneglycol, Nixolen(R), an alcohol or a polyhydroxy compound, b) a base, and c) an oxidizing agent or a source of radicals, in the absence of oxygen. The method is applicable to the decontamination of mineral oils and soil contaminated with polychlorobi phenyls, polychlorodibenzofurans, polychlorodibenzo dioxins, DDT and other halogenated organic compounds. The different possible formulations of such reagents allow the preparation of stable reactive mixture, which can be either liquid or solid; the liquid reagents are particularly suitable for the de contamination of porous surfaces such as cement, gres, asphalt and for the decontamination of parts of plants contaminated by PCBs. The use of microwaves during the decontamination process proved to be particularly advantageous.

The respective information carriers (the video tape and the sound tape) are mixed with each other in such a synchronous way that a new information carrier is provided.  For providing such a new information carrier, precise synchronism between the individual carrier tracks is necessary in all operational states.  Such a synchronism is obtained by providing a drive coupled connection between the driving means for the video tape and the driving means for the sound track.

Abstract: CAP ASSEMBLY WITH PRICTION DRAG ON TENSION BRUSH             Abstract A cap assembly for facilitating pay-off of wire past one end flange of a spool, comprising a wheel car-ried on a shaft mounted along the axis of the spool at one end, and a tension brush comprising a body having radially extending, resilient and flexible tines extend-ing to the periphery of the wheel, and adapted to be brushed by a wire strand as it orbits or traverses the spool end flange and passes over the wheel.  The wheel is rotatable on the shaft, and the moving strand imparts turning motion thereto during pay-off.  The tension brush body is also rotatable on the shaft under the action of the orbiting strand.  An adjustable braking device is associated with the brush body and shaft such that a small drag force can be imparted to the brush as it is rotating, tending to slow it down to a point where the tines are moving a a circumferential velocity somewhat less than that of the strand.  The advantage of this con-struction over the devices of the prior art is that there is minimized the tendency for the tines of the brush to move at the same speed as the strand, which would defeat the purpose of the brush.  Also, the slight drag on the brush causes the strand to be swept by the tines at a relatively slow rate, thereby maintaining the desired brushing action but eliminating fast relative movement between the tines and strand, as in the case of a stationary brush.  Higher pay-out speeds are thus at-tainable with the present arrangement than with any other known wheel/brush combinations, and significantly improved results are thereby had.

Abstract: ABSTRACT OF THE DISCLOSURE Refueling control system prevents even the slightest inaccuracy of the refuelled volume which would otherwise be caused by pressure variations inside a refuelling pipe upon activation of a pump motor for starting a refuelling operation and while no gasoline is flowing from the nozzle. The system first causes a sub-CPU to read a non-measurement time data from a host CPU in response to a nozzle signal from a refuelling unit and then inhibits counting of flow-rate pulses from the refuelling unit for a time period corresponding to this time data, which can be variably preset using an input of a host CPU.
