Abstract: INVENTOR:   MAX HAAS          INVENTION:  LIFT LANDING DOOR FRAME ARRANGEMENT     ABSTRACT OF THE DISCLOSURE     The lift landing door frame arrangement contains horizontally adjustable lateral caulking or sealing elements arranged at uprights of the door frame and a vertically adjustable top caulking or sealing element associated with the topside of the door frame.  To avoid retouching due to the caulking elements at the time of placement of the lift landing door frame arrangement and to avoid the formation of gaps in the door frame after placement, each lateral caulking element comprises a rectangular sheet metal panel of a length which exceeds the height of the door frame.  Each lateral caulking element engages with and is fixed to the interior of the related upright.  Each lateral caulking element is also guided for simultaneous vertical and horizontal adjustment at a guide plate  carried by  the  related  upright.   The  vertically adjustable top caulking element is constituted by a U-shaped sheet metal strap which is disposed astride the front parts of the door frame and is laterally guided thereat.  This lift landing door frame arrangement is particularly suitable in cases in which the lift or elevator shaft does not include lateral masonry returns at the landing openings.

Abstract: ABSTRACT             The system switches data packets, with headers, from input junctions to output junctions.          The series incoming packets are converted into parallel packets.  The headers of cash incoming packet and the identity of the involved input junction are transferred to the address inputs of a control memory.  The control memory supplies a new header which is assigned to the incoming packet, in replacement of the original header, in order to form the parallel outgoing packet with the remaining part of the incoming packet.  A buffer memory is cyclically enabled for writing, in order to store the outgoing packets.  Each parallel packet read out of the buffer memory is converted into a series packet which is assigned to the address multiplex.  Queues store the addresses of a packet in the buffer memory, and are selectively enabled for writing, depending on information from the control memory.  Each queue is assigned to an output junction.  Responsive to a signal for indicating that one of the output junctions is enabled, the address contained in the corresponding queue is read, in order to find the output packet which is to be transferred to the outgoing junction in the buffer memory.

Abstract: ABSTRACT OF THE DISCLOSURE         A four-wheel drive vehicle having straddle-type seating.  A power train is located beneath the seat and between the footpegs of the vehicle, the engine employs parallel output shafts located on either side of the crankshaft to drive power transmission means to the front and rear axles.  A speed change mechanism is contained within the engine case along with the output shafts and includes a first transmission shaft between the crankshaft and one of the output shafts.  The arrangement of the frame is such that the upper portion of the frame is narrower than the lower portion of the frame for appropriate rider comfort and footpeg location.  The wheels are located such that the front and rear tracks are substantially the same and diagonals between the wheel centers cross close to the center of gravity of the vehicle.  The cushion assemblies of the vehicle are inclined to increase cushion stroke and the steering assembly is arranged with crossing tie bars for maximum steering control with minimum mechanical complexity.

Abstract: A B S T R A C T      A method of detecting a mutation of a specific nucleotide base in a target nucleic acid chain comprises: a) hybridizing a labelled probe to the target to form a hybrid in which one end of the probe is positioned adjacent the specific base;  b) adding a nucleotide derivative, e.g. a thionucleotide, under conditions to cause it to join to the end of the probe if it is complementary to the specific base;  c) digesting the hybrid using an exonuclease enzyme under conditions such that the nucleotide derivative protects the probe from digestion;  and observing the presence or absence of label attached to the target.   The method can be used to detect mutations even when these are not present at restriction enzyme cleavage sites, and does not require the preliminary steps of restriction digestion, gel electrophoresis and DNA (or RNA) blotting.

Abstract: ABSTRACT       Cesium is recovered from cesium alum, CsAl(SO4)2, by an aqueous conversion and precipitation reaction using a critical stoichiometric excess of a water-soluble permanga-nate to form solid cesium permanganate (CsMnO4) free from cesium alum.  The other metal salts remain in solution, providing the final pH does not cause hydroxides of aluminum or iron to form.  The precipitate is separated from the residual solution to obtain CsMnO4 of high purity.

Abstract: FOR:  SYSTEM FOR PRINTING ENCRYPTED MESSAGES       WITH BAR-CODE REPRESENTATION     ABSTRACT OF THE DISCLOSURE     A system for the metering of encrypted post-age and similar indicia includes a device for printing such  indicia and a device for reading such indicia.        The printing is accomplished with a bar-code printer driven by signals obtained from a keyboard and from an encryption circuit.  The reading is accomplished with a bar-code reader to retreive the characters, and permit the  comparison  of  the  separated  coded  data  with  a reference code to determine the accuracy of the printed material.    Thereby,   forgery   and   alteration   is inhibited.  Both the data and the code are imprinted by a bar-code indicia,  a portion of the code being set aside for the data and a portion of the bar-code being set aside for encryption purposes.  Thereby,  the two portions  can  readily  be  separated  to  allow  for automatic reading of the bar code for extraction of the message, while also allowing for automatic verification by use of the encrypted material.

Abstract: Un procédé de sélection d'une station d'un ensemble de stations, dans lequel ensemble les stations constituent des groupes et dialoguent avec une station principale. Cette dernière consulte les stations groupe après groupe par diffusion d'un message de consultation dans le groupe consulté. Dans chaque groupe, les stations désirant émettre effectuent une demande de réservation d'une voie d'une liaison multiplex reliant le groupe à la station principale. Une telle demande est effectuée par chaque station désirant émettre, après qu'un temps fonction de l'adresse de la station dans le groupe se soit écoulé à partir de la réception d'un signal de synchronisation. Lorsque la station principale consulte un groupe, seule la station ayant réservé la liaison multiplex émet sur cette liaison. Un dispositif pour mettre en oeuvre le procédé est caractérisé en ce que chaque groupe comporte un bus d'auto-allocation, une liaison de signaux de synchronisation, et en ce que chaque station comporte un dispositif d'allocation relié au bus d'autoallocation et à un microprocesseur de la station.

Abstract: ABSTRACT            The invention concerns a reciprocating pump where packings (11) estab-lish a seal between the pump cylinder (9) and the plunger (10) and where the latter is connected with a plunger rod (12) that runs in a stuffing box (13) coordinated with the pump cylinder (9) cap and is driven in reciprocating fashion. To make such a reciprocating pump safe to run dry and avoid burning of the packings (11, 13a) of plunger (10) and stuffing box (13), the invention suggests providing the plunger rod (12) and the cylindrical walls of the pump cylinder (9) over their entire length with flow-through openings (9a; 12c, 12d) for a coolant flowing through them. If the reciprocating pump is driven hydraulically, the hydraulic medium suitably acts likewise as the coolant.
