Abstract: A gas turbine engine component has an annular flange arm, a backing plate mounted to the flange arm and a bypass circuit formed between the flange arm and the backing plate. The bypass circuit includes one or more channels formed in one of the flange arm or the backing plate. When more than one channels are used, at least one connecting slot is provided between the channels. At least one inlet passage extends through the flange arm in fluid communication with the forward-most channel, and at least one outlet slot is formed between the flange arm and the backing plate in fluid communication with the aft-most channel.

Abstract: The present invention provides a cervical collar preferably formed from a thermoplastic material, which includes flexibility enhancing openings which allow the collar to conform properly to the shape of a patient's neck. Most preferably, the collar is formed from linear low density polypropylene, which is an injection moldable material. The collar may be injection molded and include rivets injection molded directly as part of the collar.

Abstract: A cervical collar is provided which has front and rear semi-rigid portions, attached by hook and loop fasteners. The front portion-comprises a semi-rigid preformed jaw support contoured to follow the jaw line of a patient, and a preformed sternum brace contoured to contact the sternum and upper trapezius of the patient and to support said jaw support. The rear portion of the cervical collar is contoured to follow the curve of the back of the head or occiput and to support the head and neck. The sternum brace has right, left, and central sections, wherein the height of the central section is adapted to correspond to the distance between a patient's sternum and jaw at the chin and the height of the right and left sections is adapted to correspond to the distance between a patient's upper trapezius muscle and jaw. The height of the right and left sections is independent of the height of the central section. Further, the jaw support may include a cushioning pad and a covering of anti-decubitus material.

Abstract: The present invention provides a culture medium designated COF 1769 useful for establishing, growing and maintaining mammalian cells in culture, in particular for the establishment and culture of human normal and malignant cells. Also provided by the invention is an improved method for obtaining growth of mammalian cells.

Abstract: A variable ratio transmission apparatus for converting an input torque at a first RPM to an output torque at a second RPM includes a pair of driving discs disposed on an input drive shaft and in spaced parallel relationship thereto, a pair of driven discs disposed on an output drive shaft and a continuous length of metal link chain extending around and in direct contact with each pair of discs so as to create a high frictional force at the discs and chain interface sufficient to transmit motion from the driving discs to the driven discs. The link chain is arranged as a continuously repeating pattern of link plates which are interconnected by pins and a plurality of U-shaped drive members assembled relative to the link plates and pins. The outwardly facing surfaces of each drive member are contoured so as to conform to the surface shape of the driving and driven discs such that the chain is able to move in and out according to disc spacing, thereby realizing different radii.

Abstract: A communication system is arranged having a special hold mode (called parkhold) where a station may place any conference connection associated with that station in the parkhold mode. Any station in the system may, by transmitting a certain signal, become connected to any parked conference without regard to whether that staton has an appearance of the parked line. Selectivity is provided in that each conference is parked on a separate link and the recall signal identifies the link of any particular parked conference. This arrangement can be used for call transfer, meet-me-conferencing as well as for allowing mobility between stations in retrieving a call from the parkhold mode.

Abstract: A variable ratio transmission apparatus for converting an input torque at a first RPM to an output torque at a second RPM includes a pair of driving discs disposed on an input drive shaft and in spaced parallel ralationship thereto, a pair of driven discs disposed on an output drive shaft and a continuous length of metal link chain extending around and in direct contact with each pair of discs so as to create a high frictional force at the discs and chain interface sufficient to transmit motion from the driving discs to the driven discs. The link chain is arranged as a continuously repeating pattern wherein each pattern includes three generally triangular link plates of a clustered configuration which are interconnected by pins disposed in a first row and a plurality of U-shaped drive members connected to the link plates by pins disposed in a second row.

Abstract: A coupler unit is provided for attaching a tractor to a farm implement. The unit includes a frame pivotally attached between the farm implement and lower trailing arms extending rearwardly from the tractor. Structure is provided from the upper portion of the frame for engaging a second point on the farm implement. A coupling arm is pivotally attached at one end to the upper portion of the frame and pivotally attached at a second end to the upper trailing arm extending from the tractor.

Abstract: An arrangement for limiting the pressure developed by the combination of gases of a gaseous mixture, such as hydrogen and oxygen in a closed container, for example, in a rechargeable battery. The arrangement includes material having substantial heat capacity and having a high surface-to-volume ratio disposed in free spaces in the container wherein the hydrogen and oxygen may accumulate during the charging or discharging of the battery. When the hydrogen and oxygen combine to form a gaseous product or vapor at a high pressure, the gaseous product is cooled by the aforementioned material to limit the pressure to an amount below that capable of causing rupture of the container. The material may further, in the case of a condensible vapor such as that formed by the combination of hydrogen and oxygen effect a temperature reduction which results in condensation of the vapor to further reduce the pressure to insure against rupture of the container.
