Abstract: AN INTERFACE FACILITY FOR A                 PACKET SWITCHING SYSTEM            Abstract A communication method and packet switching system in which packets comprising logical addresses and voice/data information are communicated through the system by packet switching networks which are interconnected by high-speed digital trunks with each of the latter being directly terminated on both ends by trunk controllers.      During initial call setup of a particular call, central processors associated with each network in the desired route store the necessary logical to physical address information in the controllers which perform all logical to physical address translations on packets of the call.  Each network comprises stages of switching nodes which are responsive to the physical address associated with a packet by a controller to communicate this packet to a designated subsequent node.  The nodes provide for variable packet buffering, packet address rotation techniques, and intranode and internode signaling protocols.  Each packet has a field which is automatically updated by the controllers for accumulating the total time delay incurred by the packet in progressing through the networks.  Each processor has the capability of doing fault detection and isolation on the associated network, trunks, and controllers by the transmission of a single test packet.        The testing is done solely in response to the test packet and no preconditioning of controllers or networks is necessary.   \

Abstract: IMPLEMENT WORKING HEIGHT-ADJUSTMENT MECHANISM Abstract of the Disclosure A vehicle includes hydraulically actuated lift arms which are pivotally connected to central locations of the top of a mower blade housing and are operative for moving the mower vertically between working and transport positions.  When the mower is in its working position, a pair of caster wheels supports the front of the blade housing while the rear of the housing is supported from the lift arms by a pair of suspension assemblies.  Each of the suspension assemblies includes a fore-and-aft extending adjuster screw which is operable for effecting selected fore-and-aft movement of an adjuster bracket, which is connected to an associated lift arm by a chain, so as to cause the rear end of the housing to be adjusted vertically.  These suspension assemblies cooperate with adjustment mechanisms associated with the caster wheels to place the mower at different cutting heights.

Abstract: "APPARATUS FOR SECURING AN ELECTRONIC UNIT TO AN             AVIONICS TRAY"      This invention relates to apparatus for securing an electronic unit or the like to an avionics tray.     Electronic equipment for use in aircraft has been generally standardised into set sizes of electronic units.   These units are supported on avionics trays which are likewise of standardised sizes.     When an electronic-unit is mounted onto an avionics tray, electrical connections must be made in order to allow the proper functioning of the equipment.   Usually, the electronic unit is provided with a bank of pins which meet with a corresponding socket provided in or on the avionics tray.   Because of the delicacy of the equipment and the need to ensure proper electrical connections, the method of mounting the unit on an avionics tray, and correspondingly of extracting the unit from the avionics tray, assumes an important role. In order to ensure proper electrical connection, an appropriate degree of force is required to insert the pins into their respective sockets.  Too much force, however, could lead to damage to the electronic unit or to the connections, and therefore the appropriate insertion forces for a particular electronic unit can be defined within a relatively narrow range.

Abstract: LINEARLY REVERSIBLE CASTER ASSEMBLY                 ABSTRACT   A linearly reversible caster assembly (30) capable of carrying a load (L) on a surface (S) com-prising a pivotable U-shaped frame (34) coaxially mounted with a caster wheel (32) on an axle (48). A translatable U-shaped frame (36), suitably attached to the load (L), has planar surface (56) that coacts with a rollable surface (42) carried by the pivotable frame (34).  The rollable surface (42) has a radius greater than the wheel (32) whereby when it is desired to reverse the direction of travel of the load (L), and thus the assembly (30), the frame (34) will pivot about the axle (48) and the wheel (32) will remain substantially motionless.  As a result, the eccentricity of the caster assembly (30) is changed and the wheel (32) is linearly reversed.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved method of and apparatus for making artificial snow.  The snow making machine disclosed for practicing the invention includes a ducted fan within a housing for generating a substantially unidirectional, high volume air current over the area to be deposited with snow.  High velocity water sprays are injected into the air current from above  and below  the  air current via  a plurality  of nozzles connected to an annular water manifold circumferentially disposed around the discharge end of the housing.  Nucleated ice crystals are also injected into the air current by a high velocity vapor spray emitted from a pair of seeder nozzles disposed at the center of the housing.          The vapor spray is ccmprised of a mixture of water and compressed air which is vaporized in a venturi-type expansion chamber prior to emission through the seeder nozzles.  In accordance with a second embodiment of this invention,  a shroud member surrounds the discharge end of the housing such that a secondary airflow is guided between the shroud and housing.  The secondary airflow guided by the shroud has been found to permit greater quantities of high quality snow to be made at given atmospheric conditions and further allows snow to be manufactured in warmer conditions as compared to prior art devices.
