Abstract: ABSTRACT OF THE DISCLOSURE           A broaching machine broaches a multiplicity of generally flat work pieces having a projection at only one side, which are advanced in a single file with the projections extending in the same direction.  In order to broach the work pieces in stacked pairs in which the perpheries of the work pieces are continuous, rather than spaced apart by confronting projections, half of the work pieces are inverted and a pair con-sisting of one inverted work piece and one work piece which has not been inverted are stacked together and presented to a pot broach which broaches the perpheries of both work pieces of the pair in continuous cutting strokes.  The finished work pieces are advanced away from the broaching station in stacked condition and are separated into two groups, one of which consists of the bottom work pieces of the pair and the other consists of the top work pieces of the pair.  This places all work pieces in the same orientation with respect to the lateral projection.  The work pieces are then fed alternatively into a single file conveyor.

Abstract: ABSTRACT OF THE DISCLOSURE        An expansion dowel assembly is formed of an axially extending dowel body and an expansion member.  The dowel body has a support surface inclined relative to the axis of the dowel body along which the expansion member can be displaced by a setting tool for anchoring the dowel assembly in an opening such as a borehole.  At least a portion of the support surface is in the form of a groove formed in the dowel body extending in the axial direction of the dowel body and the bottom of the groove is inclined so that when the expansion member is displaced it is forced along an inclined path away from the axis of the dowel body, and the bottom of the groove is arc-shaped in transverse spacing.

Abstract: ABSTRACT OF THE DISCLOSURE        A novel plastic closure is disclosed having a self-engaging locking pilfer band arrangement for engagement with a locking ring on the neck of the container to which the closure is applied.  The pilfer band includes a plurality of circumferentially spaced, inwardly extending relatively thin flexible wings or fingers which move to an out-of-the-way position during application of the closure to the container.  When the closure is in place on the container, the wings are disposed such that they engage the surface of the locking ring on the container neck when the closure is moved for removal from the container.  During removal, each wing engages the locking ring so that resistance to removal of the closure is created in the pilfer bandy whereby areas of reduced strength fracture clearly indicating partial or complete removal of the closure from the container.

Abstract: ABSTRACT OF THE DISCLOSURE         The apparatus according to the invention includes a fluid pressure accumulator which is preferably precharged to a relatively low pressure at the surface, and which is brought to its final pres-sure charge after the apparatus is placed downhole in the well through a valve assembly provided in the apparatus.  Pressure charg-ing of the accumulator downhole is accomplished by exposing the accumulator to a downhole pressure, for example the casing pressure, after the apparatus is placed in its downhole position, to increase the accumulator pressure to its desired value, and then sealing off the accumulator so that its charged pressure will thereafter remain constant.

Abstract: ABSTRACT DIELECTRIC OPTICAL WAVEGUIDE AND TECHNIQUE FOR FABRICATING SAME A multilayer dielectric optical waveguide (30, 40) is formed on a III-V semiconductor substrate layer (6) comprised of either InGaAsP or AlGaAs.  A lower cladding layer (30) of dielectric material such as SiOx, (x-2) having a lower index of refraction than the substrate layer is directionally deposited on an exposed surface (17) of the substrate layer by a controlled evaporation process. A core layer (40) is fabricated on the lower cladding layer by coating an exposed surface (31) of the lower cladding layer with a dielectric material having an index of refraction greater than the index o-f the cladding layer. One material useful as the core layer is polyimide  Both one-dimensional and two-dimensional waveguides are capable of being made by appropriate addition of an upper cladding layer (50 or 60) about the core layer.  The refractive index of the upper cladding layer is less than the refractive index of the core layer.

Abstract: ABSTRACT         In a printer according to the invention, the drum has at least one slot for receiving sheet-like record car-riers, which extends in the circumferential direction and into which clamping means can be inserted for holding the record carrier with clamping fit.  The control of the clamping means is effected, for example, by means of disks which are secured adjacent the end faces of the drum and whose circumference is also engaged by the clamping means. The disks are provided at their outer side with a first stopper element, which resiliently co-operates with a second stopper element secured to the housing of the device in such a manner that upon rotation of the drum in the printing direction of rotation both stopper elements slip one over the other and upon rotation of the drum in oppos-ite direction prevent the rotation of the disk.  Thus, the clamping means are passed out of the slot.  On the con-trary, upon rotation of the drum in the printing direction of rotation, the disks, which are connected to the drum through a tensile spring, are moved in a direction oppos-ite to the printing direction of rotation so that the clamping means are thus again pressed into the slot.

Abstract: DISTRIBUTED COMPUTER CONTROL SYSTEM WITH        VARIABLE TRANSFER MONITOR TIMERS     ABSTRACT          In a distributed computer control system in which remote stations are interconnected by a communications link, the remote stations take turn having supervisory control over the communications link.  Each remote is numbered in sequence in a predetermined succession order and takes its turn having control of the communications link in accordance with this succession order.  when a remote station has completed its turn of having super-visory control, it transmits a first control message over the communications link.  The next remote station in the succession order then takes control over the communications link by transmitting a second control message over the communications link.  Each remote station has two variable timers which are set in response to the first control message and the second control message, respectively and have time out intervals depending upon the offset of the receiving remote station from the remote station which transmitted the control message.  If and when any of these variable timers times out in a given remote station, then that remote station will assume control of the communications link by transmitting the second control message on the communications link.

Abstract: ABSTRACT     Arrangements for the treatment of a moving material web by means of an air flow are used for example in the packaging industry for the drying of packing material in web-shape. In this process the web passes through a chamber provided with inlet and outlet for the air, and at high air velocities the web is affected in an undesirable manner so that an uneven, unstable movement is imparted to it.    In the arrangement in accordance with the invention this is avoided by means of a baffle plate     placed at an angle in rela-tion to the web between the web     and the outlet     which causes a partial vacuum which balances the web and gives it a calm and steady movement through the chamber    .
