Abstract: CONNECTOR FOR OPTICAL FIBERS     ABSTRACT OF THE INVENTION:     This invention provides a connector for optical fibers which includes a receptacle within which is a lens member, with plugs being connected to the opposite ends of the receptacle so that optical fibers carried by the two plugs are in a light-transmissive relationship at the lens member.  The plugs include forward tapered surfaces which are biased by resilient forces against tapered surfaces of the lens member for directly aligning the plugs with the lens member.  Each of the plugs includes a back shell carrying a clamping member in which resilient pads are biased against the fiber to grip it without damaging it.  Within the front shell the optical fiber is caused to bow in a predetermined direction which enables compensation to be made for any offset in the axes of the cavities in the lens member.  There is also a cable clamp for retaining the cable of the optical fiber unit to the connector between tapered surfaces, and a tool with an expansible loop and a stop for associating the end portion of the cable with the tapered surfaces of the cable clamp.

Abstract: METHOD FOR CONNECTING TWO MEMBERS            Abstract of the Disclosure The specification disloses a method for connecting two members together.  A circumferential groove is formed in each of the connecting surfaces of the members to be connected.  Secondly, axial recesses are formed in the inner surface of the groove.  Thirdly, a connecting member is placed between the members to be connected.  The con-necting member is made of a material which has a smaller resistance against deformation than the members to be con-nected, but which has the required mechanical strength.          Finally, the connecting member is pressed and plastically deformed, causing the connecting member to flow into the grooves and the recesses.  In this way, the two members can be rigidly connected together in a simple and econom-ical manner without requiring large scale apparatus.

Abstract: ABSTRACT     A cylinder lock comprising a stationary cylinder housing and therein a turnable cylinder inclosing a plurality of tumbler discs turnable by means of the key of the lock.  There is also a locking bar normally locking the cylinder non-turnably to the cylinder housing.  When the tumbler discs have been brought to a releasing position, the locking bar can move closer to the center of the lock into a groove formed by alignment of peri-pheral recesses in the tumbler discs, and this releases the cylin-der from its locking.  In the lock there is also at least one composite tumbler disc including two parts, a first part and a second part, which are angularly adjustably connected to each other.  The first part can be turned with a key.  Within an adjust-ment sector the first part has such a small radial extension that it leaves the locking bar free to move radially to its cylinder-releasing position.  Within the same adjustment sector the second part of the composite tumbler disc has a support surface pre-venting the locking bar from moving radially to its cylinder-releasing position but has also a peripheral recess allowing the locking bar to reach its cylinder-releasing position.  Between the first and second parts of the composite tumbler disc, there is an adjustable clutch device allowing setting of the first and second parts to a plurality of different, functionally fixed angular positions relative to each other.  There is a specially designed setting key to be used for setting of the composite tumbler disc to another position, thereby changing the lock combi-nation.

Abstract: ABSTRACT OF THE DISCLOSURE                A method is described of prestressing structural members wherein there are a pair of longitudinal elements, a plurality of strut elements and a plurality of diagonal members.  A plurality of joint connector means enable the strut elements and diagonal members to be interconnected rigidly together as an inner latticework, and the latter to the longitudinal elements.  The inner latticework is initially left freely moveable relative to the longitudinal elements, and a prestressing tensile load applied only to said latticework.  While the prestressing load is being applied, the longitudinal elements are rigidly secured to the inner latticework.  When the prestressing load is then removed, the diagonal members remain in tension, the strut elements remain in compression and the longitudinal elements acquire a compressive load.          The prestressing load should not generate any moments or rotational forces at the junctions of diagonals with the strut and longitudinal elements that have not been accounted for.  Preferably, the prestressing load is applied to the latticework in a manner so as to be colinear with the longitudinal elements.

Abstract: ABSTRACT           This invention relates generally to color copying and particularly concerns electrostatic color copying technique.         An apparatus and method for making color copies of a color original in which color resolved latent electrostatic image components of the original are formed on the surface of a rotating electrophotographic drum, developed with color corresponding development material from a developing device and then transferred to a sheet of carrier material, such as paper, in superimposed relationship.         The color resolved latent electrostatic images are formed on the surface of the electrophotographic drum by converting the color resolved image of the original into digital data, feeding the data into a computer and then writing the images on the surface of the electrophotographic drum with a laser whose output is modulated by the digital data.  The color resolved images are obtained by projecting an image of the color original through color separation filters.         The developing device includes a  plurality of developing units, each containing developing material whose color corresponds to one of the color image components of the color original.  The developing units are moved past the drum, seriatim in a stepwise cycle.  The movement of developing device and the electrophotographic drum are coordinated so that each developing unit will apply developing material to its corresponding latent electrostatic image during the dwell period of the developing device when said developing unit is in toner applying relation with the drum.

Abstract: ABSTRACT OF THE DISCLOSURE          A separation device, comprising an assembly of substantially parallel corrugated plates arranged in a basin at an angle with the horizontal plane, defining therebetween  separation passages through which the liquid to be treated is passed as a flow crossing the corrugation axes, so that the components separated from said flow will be removed between the corrugations and transversely to the liquid flow, and shielded from the latter by said corrugations, towards discharge passages at an extremity of said plates, in which passages guiding baffles are provided for suppressing short-circuit flows past the plate assembly. The improvement is that the plates extend up to the lateral walls of the basin, contacting the wall in question in alter-nating extreme points of the corrugations, the intermediate extreme points in which the separated components are being discharged remain-ing at a distance from said wall thus providing discharge passages, the guiding baffles being provided in at least a part of the latter. At least a part of the corrugated plates can be provided with cut-outs so as to widen the discharge passages. For simplifying mounting and cleaning groups of plates are combined to subassemblies by means of draw-bars and distance pieces, and in the corners of the assembly smaller subassemblies can be arranged so as to fill substantially the whole cross-section of the basin.
