Abstract: A display assembly (FIG. 1) comprises a plurality of panels (1) joined together by elongate connecting members (2, 3). Each panel has a removable frame formed by extrusions (6) in each of which is a slot (13) having a restricted entrance (FIG. 2). Each connecting member (2, 3) has two heads (18) which can be slid into slots (13) in adjacent panels (1), from one end, to join the panels together, each head being too wide to pass through the restricted entrance of the slot. A central body portion (20) of the connecting member, to which the heads (18) are joined, is positioned between, and extends outwards between, adjacent panels to facilitate access to the connecting member and enable the screen assembly to be dismantled easily. A longitudinal slot (50), (FIGS. 21 to 23), can be provided in a part of the body (20) that is accessible between connected panels, to enable components such as shelf-supporting brackets to be secured to the screen assembly.

Abstract: In a exemplary computerized FM Data Transceiver terminal, an antenna may extend longitudinally from one end and a battery drawer at an opposite (lower) end may receive a detachable bar code scanner module or the like for mechanized data input. In such computer terminals which are hand-held for relatively long time periods, e.g., during inventory data collection, use of the terminal is particularly facilitated by indenting the underside of the terminal intermediate its ends to form a hand grip configuration and by providing a strap spanning the indentation such that the fingers of one hand can be inserted between the hand grip and strap in a quick smooth motion without requiring as a separate motion the lifting of the strap to accommodate the fingers. These features coact to provide for an outstandingly comfortable and secure gripping of the terminal during use.

Abstract: A controller operates in pre-ignition and ignition phases to obtain stable and reliable control of operation of a half-bridge DC-AC converter in a frequency range which is offset from a resonant frequency of an output circuit which includes a transformer and capacitors and which couples the converter to a fluorescent lamp load. The converter is supplied with a DC voltage from a switched-mode DC-DC supply of a pre-conditioner circuit which responds to a full-wave rectified AC voltage and which is supplied with pulse-width modulated gating pulses from the controller, preferably at a frequency which is the same as that of the converter. The controller monitors signals from the output circuit and pre-conditioner circuits and exercises control to reliable starting and highly efficient lamp operation and to obtain an in-phase proportional relationship of input voltage and current waveforms.

Abstract: Capacitor ignition systems for internal combustion engines in which a charging winding forms part of an ignition coil and a primary winding is connected in circuit with the charging winding to contribute to capacitor charging. In one embodiment, the secondary winding is also connected in circuit with the charging winding which contributes to development of an output voltage. Circuit components are provided for insuring a high output voltage while protecting a charging diode against excessive inverse voltage during ignition and for protecting the gate of a thyristor switch from an excessive negative voltage.

Abstract: A collapsible foldable dispensing carton is provided which includes pairs of first and second top closure flaps foldably connected to upright wall panels, the latter being foldably interconnected. When the carton is in a set up mode, pairs of wall panels are in spaced, opposed relation. When the closure flaps are in an overlapping close relation, one of the first flaps is the outermost flap and is provided with a dispensing opening. A fitment of thin material is mounted on an exposed surface of the outermost flap and in registry with the dispensing opening. The fitment includes a base section which is affixed to the exposed surface portion of the outermost first flap circumjacent the dispensing opening. The base section is provided with an aperture in registry with the dispensing opening. The fitment also includes a hingedly mounted cover section movable relative to the base section between fully open and close modes.

Abstract: A diaphragm operated valve assembly is controlled by an electromagnetic valve assembly. A flat disc armature, which forms part of a flux path, is operable in an inner chamber to modulate the flow between the inner chamber and an exit port in response to an applied magnetic force. The level of the effective magnetic force is a function of the armature mass, and the pressure acting on the disc surface. A pole piece adjacent to the flat disc armature is slidably adjustable to establish a specified force to actuate the armature to the closed or sealing position. This specified force is proportional to the current flow through the winding of the electromagnetic valve assembly. Thus the armature operates to seal communication between the inner chamber and the exit port at a given pressure differential as a function of current flow. The travel distance between the armature and a nonmagnetic seal seat has been minimized by spring biasing the armature in proximity to the seal seat.

Abstract: A container shroud which is a unitary, molded plastic article is comprised of a substantially cylindrical portion for engaging the body of a vial as well as helical rings or ribs located on the interior wall of the cylindrical portion which serve to grip the periphery of the vial.

A first playing surface which accommodates four players is divided into four playing areas and each playing area is divided into identical playing spaces. Players are assigned a playing area and the player's playing pieces are placed in the respective playing areas. The playing pieces move along the playing surface and opposing playing pieces may be captured. A second surface on the opposite side of the board discloses another embodiment of the game wherein the second playing surface is divided into six playing areas, one playing area assigned to each player.

Abstract: The present invention provides a connector having a seamless tubular metallic shell which not only provides proper RFI/EMC shielding but also is constructed in such a way as to prevent ingress of moulding material into the spaces between contacts of the connector. This is achieved by forming one end of a seamless tube of ferromagnetic material (which is initially of substantially uniform cross-sectional area) such that is collapsed on to itself and a cable connected to the connector whereby to tightly seal the send of the tube on to the cable to prevent ingress of moulding material subsequently applied to the exterior of the shell. In the case of a cable providing a braid or foil shielding element, this process simultaneously provides an electrical bond between the shell and a portion of the shielding element of the cable exposed by removing a portion of the outer insulation covering of the cable.

Abstract: In an exemplary communications system a multiplicity of mobile terminals are to share a communications link with a primary processor. The primary processor may transmit a multiterminal polling signal defining a series of successive response time slots which the terminals may randomly select. A terminal wishing to send a message transmits a brief response burst in the selected time slot giving its identification. The primary processor may then sequentially poll specific individual terminals having messages to send. The primary processor may maintain a record of currently active terminals and/or of collisions (where more than one terminal seeks to transmit in the same response time slot), and as needed may automatically send e.g. with its multiterminal poll, a time slot number change, creating a greater or lesser number of time slots for future use by the active terminals.
