Abstract: A large diameter nose bar roll apparatus for a veneer lathe is disclosed including an automatic knife gap adjustment means (64). The knife gap adjustment means reduces the knife gap between the nose bar roll (10) and the knife blade (14) during peeling in response to decreases in the log diameter and/or changes in the knife pitch angle. This knife gap adjustment maintains the nose bar roll in contact with the log (12) at the proper contact pressure as the diameter of the log decreases during peeling. This is necessary for nose bar rolls having a large diameter of at least 1.5 inches and 15 times the thickness of the veneer such as, for example, a nose bar roll of 3.75 inches diameter. An electrical control means is employed for automatically controlling the knife gap adjustment means by moving the nose bar roll toward the knife in response to decreases in the log diameter and changes in the pitch angle. The nose bar roll may be driven by power means (46) to apply an auxiliary driving force for rotating the log in addition to the powered spindles (16) provided at the opposite ends thereof for rotating such log during peeling.

Abstract: A three-phase supply system is described which has particular application for single to three-phase converters and variable speed three-phase a.c. motor controllers. This is achieved by using a solid state six element voltage-source inverter (20) to achieve and control the dual conversion of voltage and frequency. The solid state unit is used in the single to three-phase converter and in a three-phase to three-phase converter and consists of six power switches (34), (gate turn-off switches (GTOs)) which invert the fixed d.c. voltage derived from a recti­fied single-phase or three-phase a.c. mains (12,82) to provide a required symmetrical three-phase output supply (22). The use of solid state elements enables the unit to be controlled from a processing unit (54) which can be programmed and set so that the output voltage and frequency is carefully controlled to meet supply requirements for both the three-phase power supply and to achieve variable speed a.c. motor control.

Abstract: A high-performance deflection yoke (50) providing deflection of an electron beam in a CRT (52) at high rates at high deflection angles. The high-performance deflection yoke (50) includes a heat sink (54,56) con­tacting the coils of the deflection yoke (50) to remove the heat produced in the deflection yoke due to core losses and heat produced in the deflection coils due to resistive losses. The heat sink minimizes induced eddy currents and comprises fine wire elements, inter­woven and/or in juxtaposition with the deflection coils, wherein the heat created within and picked up by the deflection coils is transferred to the heat sink for dissipation. By minimizing power loss in the heat sink due to inductive heating of the metallic components thereof, the heat sink according to the present invention provides a high-performance deflection yoke having low inductance, high power performance not heretofore practically realizable.

Abstract: Apparatus used in a relational data base system to maintain a dependence between a user-defined field in a row of one base table (101) and the state of a set of rows in another base table (101). There are three kinds of dependent fields: a count field (107) which contains a count of the rows in the set, a sum field (105) which is the sum of a field in the rows of the set, and a base copy down field (113) which is a field in the rows of the set which contains a copy of a value in a field in the row of the one base table. The two base tables make up a referenced-referencing pair and the row from the one table has a primary key (103) which is used as a foreign key (111) in the set of rows of the other base table. The apparatus consists of components (313, 306) in the data dictionary which define the user-defined dependent field and the nature of the dependence, including any conditions thereon, and components (319) in the data base system's run time system for maintaining the dependence. Each time the state of a row in the referencing base table is altered, the run time system uses the data dictionary to determine whether there is a user-defined dependent field, and if there is, what kind of dependent field it is. Code in the run time system then reestablishes the dependence as required for the altered row.
