Abstract: Abstract of the Disclosure Light fixtures with a rod-shaped light source (1) and with concave reflectors on both longitudinal sides of the light source.  The concave reflectors extend above the light source, and have a curvature such that all light rays reflected across the light source will emerge in the transverse direction either directly or after reflection at an angle that is steeper than a light-specific masking angle (.alpha.).  The reflectors include lamellae (4) that have an approximately V-shaped cross section and run across the middle vertical longitudinal plane of the light source and have reflecting concave side surfaces with a curvature such that all light rays reflected in the longitudinal direction of the light source (1) will emerge in the longitudinal direction either directly or after reflectiona t an angle that is steeper than a light-specific masking angle (.beta.). the top sides (8) of the lamellae are covered by a flat reflecting cover, and the lamellae are shaped so as to form two lamellar sections that are symmetrical with the middle vertical longitudinal plane; their flat top sides, starting below the light source, form an angle with the longitudinal plane that approximately corresponds to the masking angle (d) and have the opposite slopes such that they are in tangential proximity to the light source (1) but do not come in contact with it, and they extend as far as the reflectors (2).

Abstract: ABSTRACT         "DIGITAL TELECOMMUNICATIONS SYSTEM"   The digital signal multiplexing arrangement has at least one multiplexer (1,2) and at least one demultiplexer (6,7) for pulse frames having a plurality of useful information channels. The transmitting section has a data protection coder (3) whereas the receiving section has a data protection decoder (5). The data protection coder (3) produces an error protection code dependent on errors detected in predetermined ones of the useful information channels and inserts the error protection information into one or more of the useful information channels or into one or more dedicated portions of the useful information channels. At the receiving end, the data protection decoder (5) recognises and corrects errors in the predetermined channels of the transmitted t.d.m. signal. In this way, all or some of the useful information channels, which are provided, for example, for data transmission, can be transmitted with a lower bit error quota without thereby departing from the standardised hierarchy stages of the transmission systems.

Abstract: SAFETY SHEAR APPARATUS AND METHOD       FOR PRODUCTION WELLS                         Abstract An apparatus and method for shutting in a well in the event all other control equipment on the well fails to close and hold.  The apparatus includes a lower and upper tubing head in which the tubing extends from the well upwardly through the lower head and into the upper head and sealingly engages both heads.  A sealing and shear ram is positioned between the heads for shearing and sealing the tubing.  The shear tubing is moved away from the shear rams after shearing to allow the rams to seal.  The tubing is preferably supported from only one of the tubing heads.  In one embodiment the tubing is supported initially from the upper head and after shearing the lower tubing portion moves downwardly to seat on the lower tubing head for allowing the rams to seal.  In another embodiment the tubing is supported from the lower head and after shearing the upper portion of the tubing is raised to allow the shear rams to seal.

Abstract: DATA PROCESSOR HAVING DYNAMIC BUS SIZING                   Abstract of the Disclosure In a data processor adapted to perform operations upon operands of a given size, a bus controller is provided to communicate the operands with a storage device having a data port which may be a submultiple of the operand size.  In response to a signal from the bus controller requesting the transfer of an operand of a particular size, the storage device provides a size signal indicating the size of the data port available to accommodate the requested transfer. Depending upon the size of the operand to be transferred and the size of the data port of the storage device, the bus controller may break the operand transfer cycle into several bus cycle in order to completely transfer the operand.  In the process, the bus controller compensates for any address misalignment between the operand and the data port.  In order to distinguish individual operand cycles from the several bus cycles which may comprise the operand cycle, the bus controller provides an operand cycle start signal only at the start of the first bus cycle of each operand cycle.

Abstract: Abstract of the Disclosure A  bender  for  plastic  printing  plates locates the line of fold from the leading edge of the plate by providing positioning means adjacent the die surface.  The printing plate is placed on a flat base and adjusted to engage the positioning means,  the latter in alignment relative to the die.  Next, a guide means lifts an edge segment of the plate into a position for engagement by a chan-nel carried by the die.  As the die swingably moves through an arc, the edge segment is reversely folded back and into contact with an adjacent area of the sheet while forming a crease sufficient to overcome a substantial part of the memory of the sheet along the line of fold.  Consequently, plate image will be precisely parallel to the line of fold, thereby minimizing setup time.   Also, plates of various lengths may be bent without adjusting the bender.

Abstract: ABSTRACT An energy-absorbing element is provided between an insulative piston and a movable contact of a switch for a high-voltage device. In arrangements where a fusible element is in electrical shunt with the switch, the energy-absorbing element improves the rapid commutation of the current from the switch to the fusible element where final circuit interruption takes place. The switch is of the general type in which ignition of a power cartridge moves the insulative piston, which is normally located in a bore formed in a conductive member, away therefrom and into a passageway formed in an insulative liner. The movement of the piston moves the movable contact through the passageway and away from the conductive member to break an electrical interconnection between the conductive member and the movable contact. This forms a gap between the conductive member and the movable contact and opens the switch. The ignition of the power cartridge evolves high pressure within a chamber defined by the piston and the bore. This high pressure acts against the piston and the resulting forces rapidly drive the piston; the movable contact being driven via the transmission of forces through the energy-absorbing element. The energy-absorbing element enhances the rapid and simultaneous movement of the piston and the movable contact. The energy-absorbing element absorbs sufficient energy at the interface between the piston and the movable contact to prevent undesirable reaction effects which may be caused by the reaction or rebounding forces between the piston and the movable contact.
