Abstract: Abstract In hydrodynamic bearings it is necessary for the lubricant leaving the lubricant film to be cooled. The self-sufficient, reliable operation of the system is only ensured if the transport of lubricant can be generated and maintained by the bearing itself. For this purpose the lubricant is taken from the contact surface of the moving component (2) into a pumping gap (13), recessed in the stationary component (4), which exhibits a strong constriction (17) in the direction of movement by a graduation (16). This pumping gap (13) may be machined directly in the contact surface of a bearing segment or in a separate component. A part of the lubricant stream which enters the pumping gap (13) is removed in front of the constriction (17) through an appropriate lubricant discharge duct (14). This branched lubricant stream (19) represents the delivery quantity of the pumping gap (13), the remainder flows on through the lubrication gap (18). The pumping pressure corresponds to the pressure built up hydrodynamically in the pumping gap (13).

Abstract: CONTROL OF AC POWER TO INDUCTIVE LOADS     Abstract of the Disclosure A control system is provided for controlling the average power from an alternating voltage source (AC) to a load having inductive properties.  The system uses a synchronous switch shunted by a capacitor connected between the source (generator) and sink (load) to pulse duration modulate the AC voltage carrier wave.   A control signal generator circuit drives the synchronous switch such that the switch is closed at a variable time early in each half-wave of the AC voltage source carrier wave and such that the switch is opened at a subsequent later, variable time during that half-wave.  This is accomplished by sensing the voltage across the synchronous switch in order to inhibit closing of the switch early in the half-wave until the synchronous switch voltage (and thus the voltage on the capacitor) is substantially zero and then opening the synchronous switch at a point in time to give the desired volt-second area between closure and opening within each half-wave.

Abstract: A SELF-ROUTING PACKET SWITCHING NETWORK WITH INTRASTATE PACKET COMMUNICATION     Abstract A communication method and packet switching system in which self-routing packets are communicated through the system by intra-communication of the packets within the stages of the network as well as inter-communication of the packets among stages.  The switching network comprises stages each having a plurality of pairs of switching nodes with each pair having an intra-node between the pair of nodes.  Each of the switching nodes comprises input controllers and output controllers.  The input controller of a node is responsive to the receipt of a packet for interrogating the address field of the packet to determine the destination of the packet.  The input control on the basis of the destination determination communicates the packet towards the destination via either an inter-stage link or an intra-node link on the basis of availability of the links and an internal control circuit.  If a packet is transmitted via an intra-node link to the paired node the latter then transmits the packet via its output controller to the next stage via an inter-stage link.  If both the intra-node link and the inter-stage link are available, the internal control circuit then determines which link should be utilized in communicating the packet.  The internal destination circuit performs this designating function on the basis of a random number generator.

Abstract: MERCURY PUMP                 ABSTRACT OF THE DISCLOSURE A mercury pump for analyzing geological core samples has a vertically oriented cylindrical cavity in which a lower portion forms a mercury displacement chamber and an upper portion in axial alignment with it forms a sample chamber.  A pressure transducer, e.g., a strain gauge or solid-state sensor, in communication with the sample chamber produces an electrical pressure signal.  A screw ball jack urges a synthetic-resin piston upwards in the displacement section to push the mercury into the sample chamber.  The displacement of the mercury is sensed by an electronic encoder coupled to the hand crank of the jack, and provides data regarding both the direction and the amount of piston displacement.  A microprocessor-controlled volume-measuring device has inputs connected to the encoder, and automatically provides core sample data, in response to the signals from the encoder, at the end of a core test run.

Abstract: "TIE SUPPORT SYSTEM FOR MASONRY VENEER"     ABSTRACT OF THE DISCLOSURE         Conventional  masonry  support  ties  extend through insulation or sheathing and are secured to metal or wooden studs.  In order to secure same, the insulation or sheathing material is often compressed so that suf-ficient support is provided.  This lowers the insulation value and permits moisture penetration either of which may allow movement of the veneer and which may cause cracking or deterioration thereof.   The present system provides a support or tie which may be applied on top of the insulation or sheathing and which will transfer the load directly to the face of the stud without compressing the insulation or sheathing.   It comprises a length of channel having four pointed legs extending perpendicular to the plane thereof which assist in piercing the insula-tion or sheathing.   The length of the legs are substan-tially  equal  to  the  thickness  of  the  insulation  or sheathing so that no compression takes place yet because the points of the legs engage the face of the stud, the tie  support attached thereto enables the load of  the masonry veneer to be transferred directly to the face of the stud.

Abstract: ALTITUDE LOSS AFTER TAKE-OFF WARNING         SYSTEM UTILIZING TIME AND ALTITUDE           Abstract of the Disclosure Warning systems for aircraft that provide a warning to the pilot of an excessive altitude loss or an excessive descent rate after take-off as long as he is flying below a predetermined altitude save the problem that they require a valid radio altitude signal for proper operation, and tend to generate nuisance warnings when used in low flying aircraft.  This problem is solved by comparing the accumulated altitude loss after take-off (12, 14, 62, 34) with the product of a barometrically derived altitude and the length of time the aircraft has been flying (12, 14, 30, 32, 34).  A warning is generated if the altitude loss is excessive for the accumulated time-altitude product after take-off (38, 40). Thus, the system is more sen-sitive immediately after take-off and becomes less sensitive as flight time is accumulated to permit low level maneuvering without generating false or nuisance warnings, and does not require a valid radio altitude signal to generate a warning.

Abstract: LINE CIRCUIT FOR DRIVING A RINGER AND A SERVICE INDICATING LAMP IN A TELEPHONE SET     ABSTRACT OF THE DISCLOSURE      A line circuit for driving a ringer and a service indicating lamp in a telephone set, including a high frequency transformer (T2), a switching circuit (22) for intermittently disconnecting a D.C. voltage applied to the primary winding of the transformer (T2), and a control signal generating circuit (23).  The control signal generating circuit generates a first control signal having high frequency and having a first duty ratio when the ringer is to be rung; and generates a second control signal having the same frequency but having a second duty ratio smaller than the first duty ratio when the service indicating lamp is to be lit. The first or the second control signal is applied to the switching circuit so that the high frequency transformer generates a ringing signal or a D.C. voltage to light the lamp. Since the high-frequency transformer is commonly used for generating the ringing signal and the D.C. voltage for the lamp, the line circuit can be made small and light.
