Abstract: ABSTRACT      A piston  (10)  and piston rings  (16,  17,  18) assembly.  The piston rings (16, 17, 18) include a flat cylindrical face (20) and a support structure for supporting the face (20)  such that under load the ring deflects so that the. face  (20)  forms a hydrodynamic  wedge between the  face  20  and the cylinder wall.   The support structure includes a pair of circumferential ligaments (22, 24, 34, 36, 45, 46) arranged relative to the face (20) of the ring 50 as to intersect at a point (25) in front of the face 25.   The support structure may further include dog legs (37, 38, 47, 48).   The face (20) may include scraping edges  (42,  44).   The piston ring may include an oil duct (50).

Abstract: MOBILE RADIO DATA COMMUNICATION               SYSTEM AND METHOD          ABSTRACT      In an exemplary embodiment, a test signal is sent by a base station at a suitable point in a communi- ications protocol.  According to the evaluation of the test signal transmission, a relatively high data rate or a lower more conservative data rate is selected by a mobile unit for the transmission of a relatively lengthy data message.  The test signal can be associated with a query from a mobile unit having a message to send, or with a contention polling message from the base.  Such test signal can be transmitted at the lower data rate where its transmission characteristics (e.g. signal strength, jitter or quality of transmission of known information) can be used to predict probable feasibility of transmission at the higher data rate, but most preferably the test signal is part of a high data rate contention poll which may alternate with a low data rate contention poll.

Abstract: Abstract of the Disclosure.      The invention relates to a self-aligning coupling for connecting laboratory animal cages to a drinking water supply.  A male coupling is attached to a grommet assembly at the back of the cage and a female coupling is assembled to a fluid supply manifold at the back of a shelf located so that when the cage is placed on the shelf and translated to the rear the male coupling will automatically connect to the female coupling and water supply.   The grommet assembly allows the male coupling to be self-aligning in angular and radial directions to facilitate coupling.

Abstract: A vascular graft is used to supply blood to one or more coronary artery branches. The vascular graft has an elongated U-shaped tubular body providing a continuous passage for carrying blood from a high pressure blood supply to a blood receiver. One or more openings in the body allow blood to flow into the coronary artery branches. The flow and pressure of the blood in the passage is controlled by a restriction providing a Venturi passage located remote from the inlet end of the tubular body. The restriction is reinforced with an annular sleeve to maintain a desired cross sectional area and length of the Venturi passage. The pressure differential between the blood supply and blood receiver maintains continuous and adequate blood flow at a desired pressure in the body passage and provides a continual supply of blood for the coronary artery branches.

Apparatus for making filaments; cellulose - xanthates, processes for making filaments from.- In the manufacture of viscose silk, transference - of the material from the original collecting spools is avoided by employing a foraminated spool made from a material which resists the action of the desulphurizing-mechanism, and by subjecting the silk while on this spool to the several baths required for the purpose of removing acid, bleaching, desulphurizing, soaping, &c., the baths being caused to flow through the material. Suitable materials for the spools are stainless steel and ceramic materials. As a modification, the silk is partly treated on the original foraminated spool and then transferred to a foraminated twisting spool, the treatment being completed while the silk is on the second spool. By forcing the baths through the silk the duration of the treatment is appreciably shortened. Specification 250,303 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes an arrangement, for use in carrying out the treatment, comprising a spool a of stainless steel covered with a layer b of felt, on which a mass c of silk is spun. The treatments are carried out in a vat d provided with pipe connections f to an exhaust pump, the pipes leading from seatings i; the spools are piled up on the seatings, packing pieces g being placed between their ends, and the exposed end of the uppermost spool being closed by a stopper h. The Specification refers also to the creation of a vacuum within the spool for the purpose of causing the passage of the liquid therethrough. This subject-matter does not appear in the Specification as accepted.

Abstract: The invention relates to a method and to an arrangement for controlling the respective conduction times of two directionally opposed electrical devices (9, 10) which are mutually connected in parallel and permit current to pass therethrough solely in one direction, and which also permit current (l<sub>2</sub>) to pass through the primary winding (2) of a transformer during a respective half-period of an A.C. voltage (U,) applied to the primary winding, this control being effected so that the magnetizing current through the transformer can be advantageously minimized and/or held beneath a given limit value when an asymmetric load (4, 5) is applied to the secondary side (3) of the transformer. A magnetizing current in the primary winding corresponding to the load (5) of the secondary winding (3) is controlled through the agency of different conduction times of the two directionally opposed devices (9, 10).

Abstract: Compositions of matter, including: A mixture of at least one oxide of manganese and at least one oxide of a Lanthanum Series metal, preferably lanthanum or cerium, or at leaat one oxide of niobium. The above compositions are particularly useful as catalytic compositions for the conversion of C<sub>3</sub> and C<sub>4</sub> hydrocarbons to less saturated hydrocarbons, particularly ethylene and propylene and preferably ethylene. The life of the catalyst for the selective production of ethylene is extended by carrying out the reaction in the presence of steam. The steam substantially increases the active life of the catalytic composition, before regeneration is necessary, as well as significantly increasing the selectivity to ethylene. Limiting the amount of "bound" or "fixed" sulfur in the catalytic composition also improves the catalyst.

A satisfactory line connection between the S/T interface and the NT is indicated if the response from the NT is a predetermined response, while an unsatisfactory line connection is indicated if the response is not said predetermined response. A plurality of additional tests are performed after the initial line connection test to determine the location of a problem in said line connection if the initial line connection test indicates that the line connection between the S/T interface and the NT is unsatisfactory.

Abstract: ABSTRACT OF THE DISCLOSURE   In a satellite communications system, a time slot assignment signal and a reference timing signal are transmitted from a central station to terminal stations to allow them to send bursts on assigned time slots and to establish the frame timing. In the central station, first and second self-resettable counters increment their respective binary counts at clock intervals and reset their counts to an initial value at time-slot intervals. A local timing signal is generated synchronously with the reference timing signal and delayed by an amount corresponding to a minimum round-trip propagation delay to reset the first counter. In an initial, wide aperture mode, the output of the first counter is used to generate control signals for recovering a carrier and clock and widely opening an aperture gate for detecting unique words of a burst that is affected by satellite drift. If a unique word is detected, the central station switches to a narrow aperture mode in which the output of the second counter is used instead to generate control signals for recovering the carrier and clock and narrowly opening the gate to reduce the possibility of detecting false unique words. In a preferred embodiment, the output of the second counter is stored in a memory in response to the detection of a unique word and an average value of the stored counts is derived to optimize the reset timing of the second counter.
