Abstract: COMPUTER-COMMUNICATIONS CONCENTRATOR FOR TRANSMISSION AND       SWITCHING OF PACKETIZED DATA          ABSTRACT OF THE DISCLOSURE   A-computer-communications concentrator for establishing connections between a plurality of asynchronous computer-communications terminals and a two-way computer-communications channel for transmission and switching of packetized data.  The concentrator is comprised of one processing unit which is operated asynchronously and is connected to the computer-communications terminals.  One packet communication protocol standard normalizing function processing unit, preferably of the well known X25 interface is connected to the two-way computer-communication channel, with, between the two processing units, a communication system comprised of one memory unit having a first part in which each packet transmitted in one or the other direction is stored, and a second part comprised of forward and return cell pairs.  Each cell is provided to store a packet header during a transfer into the communication system, each local header containing the address of the packet stored in the first part of the memory unit, its length, and some data relevant to the type of packet, the interpretation of which is used to determine in the processing unit which reads it, the appropriate processing to be done for the packet at hand.  Each link between a terminal and the two-way channel makes use of a couple of selected pairs of cells, each packet being stored in a location available from the first part of the processing unit which introduces this packet into the memory inserting a local header in the corresponding outgoing cell from the associated cell pair, then transferring this local header into the return cell of the other pair from the set associated with the unit which will output the packet from the memory unit when this cell is available as indicated by a particular value of the packet type information.

Abstract: Docket M-387 Abstract of the Disclosure There is disclosed a hand-held label printing and applying apparatus having an impression control mechanism. The apparatus includes a pair of relatively movable slides.  A first slide is driven in response to movement of a manually operable actuator and a second slide which carries the print head is slidably mounted on the first slide.  During the initial actuation of the actuator, the first and second slides move as a unit until the second slide is stopped by a shoulder of a latch.  Continued movement of the actuator and travel of the first slide causes energy to be stored in a spring arrangement. Upon further movement of the actuator and continued travel of the first slide the latch is tripped and the spring arrangement drives the second slide and causes the print head to be driven into a straight line into printing cooperation with the platen.  There is also enclosed an arrangement by which the print head can be releasably connected to the second slide.  The apparatus also includes an improved spring assembly.

Abstract: TITLE               FLUID ACTUATED PUMP SYSTEM            ABSTRACT OF THE DISCLOSURE           A pump system includes a source of fluid under pressure conveyed into a fluid chamber containing meshing gears which are rotated by the pressurized fluid to, in turn, transmit rotation to a unitary valve member positioned in a housing. Rotation of the gears also displaces fluid at a preselected flow rate through an inlet port of the housing and into a first inlet port of the rotary valve member.  During the first one half cycle of rotation of the rotary valve member, fluid is conveyed through a first set of aligned outlet ports of the valve member and the valve housing to a water pump for displacing a water piston. The water piston is displaced to convey water through a first conduit.  During the second one half cycle. of rotation of the rotary valve member, fluid is conveyed through a second set of aligned outlet ports of the valve member and the valve housing to displace the water piston in an opposite direction to convey water through a second conduit.     By continuously rotating the unitary valve member, fluid under pressure is alternately supplied to inlet ports of the water pump to reciprocate the water piston.  For the first and second conduits having nozzle end portions, this arrangement generates a continuous spray which is adaptable in underground mining operations to suppress the circulation of dust in the mine atmosphere by directing the water spray upon the mine face as the mineral material is being dislodged.

Abstract: APPARATUS AND PROCESS FOR HOT-STAMPING CONTAINERS                        ABSTRACT      Apparatus (12,14,22,27,29) and process for hot-stamping molded plastic containers (10) in which the container (10) is moved past a heated die (96) having a platen (101) with a printing die (110), the die (110) being floatable movable so that linear uniform pressure is exerted between a confronting container surface and die surface.  As the container (10) moves across the die surface (110), it is rotated so that foil (24) which is pinched between the container (10) and die (110) is transferred onto the surface of the rotatable container (10).  The uniform linear pressure between container (10) and die (110), transfers foil (24) to the accompaniment of rotation of the container (10) so that defect-free lamination of foil (24) is transferred onto the container surface to form decorative or alpha numeric information.  The operation is continuous, with successively spaced containers (10) moving into printing position relatively to the die (110), where the hot-stamping operation is repeated.  Containers (10) are automatically removed after printing, and successive containers (10) supplied either manually or automati-cally.

Abstract: INVENTOR:    Robert W. Carlson TITLE:       VEHICLE ACCELERATION/DECELERATION WARNING              SYSTEM                  ABSTRACT OF THE DISCLOSURE           A compound pendulum allows light to impinge upon properly positioned acceleration or deceleration photocells to vary the resistance of the photocells in accordance with the angular displacement of the pendulum; the amount and direction of angular displacement of the pendulum is dependent on the amount of acceleration or deceleration of the vehicle.          Variation of the deceleration photocell resistance varies the frequency of an oscillator circuit to alternately flash a pair of warning lights at a frequency dependent on the rate of deceleration of the vehicle.  The acceleration photocell must receive maximum illumination (a threshold value) to actuate a light for warning of a minimum rate of acceleration of the vehicle.  A manual switch allows a high flash rate of alternate warning lights to be controlled by the operator of the vehicle.  An audio generator produces a continuous tone for acceleration and an interrupted tone for deceleration, the frequency of interruption corresponding to the flash rate of the deceleration warning lights. The system is an  aid in preventing rear end collisions and will save gasoline if properly used.

Abstract: APPARATUS FOR APPLYING LIQUID   CHEMICALS TO A MOVING WEB                    ABSTRACT          In a preferred embodiment of the invention, a manifold in the form of a pipe having a closed end is utilized to supply a finishing agent to orifices arranged at spaced intervals along the pipe.  A foam material surrounds the manifold to receive the finishing agent and to apply it in a thin film to the curved surface of an element comprising a longitudinal section of a cylinder.  The film is retained on the curved surface by surface tension as it moves under the force of gravity to a longitudinal edge of the cylindrical section.  A web of fabric is tensioned against the section edge as the fabric moves past the cylindrical section.  The direction of fabric movement is such that the film of finishing agent is applied to the fabric immediately ahead of the line of contact between the fabric and the section edge.

Abstract: ABSTRACT OF THE DISCLOSURE           A pressure-resistant thermoplastic bottle has a low center of gravity and a dimensionally stable seating ring zone of substantial strength.  The center of gravity is lowered by reducing the weight of the finish and neck, and using a larger diameter for the main body to reduce the overall height while maintaining the desired internal volume.  The improved design of the seating ring results in a thicker wall in the bottom end and, therefore, a stronger structure.  The bottom end includes a sharp V-shaped structure having a concave in-side wall and a generally convex outside wall joined at the bottom ends by a lower end portion which is concave at its outer surface.  A convex central portion is connected to an upper end of the inner wall to define a central cavity and an extreme lower end of the outer wall is generally concave.
