Abstract: In a production method and system, a set of camera frame assemblies are partially assembled and a film unit is loaded. Each camera frame assembly is disposed on a pallet. Each pallet has a unique machine-readable designator. Defects are found in one or more members of the set of camera frame assemblies and a record is made of the respective designators of the pallets bearing the camera frame assemblies having defects. Assembly of the camera frame assemblies is then concluded. Afterward, camera frame assemblies on pallets having designators in the record of defects are culled. The assembly has the pallets, a transporter, a plurality of assembly devices, a series of defect inspectors, and an alteration unit that prepares for culling film rolls of camera frame assemblies having defects. The alteration unit transmits camera frame assemblies that are free of the defects without the preparing.

Abstract: A head rest attachment is provided for tubular frame lawn or patio furniture. The head rest attachment includes a curved head support surface, and a resilient adjustable clamp for attaching the supporting surface to the top of the back tubular member of the lawn or patio furniture so that a head supporting force is created along a line between the centers of the supporting surface and the tubular member. For added comfort the head support surface may be padded. Further, the head support surface may be concave and extend upwardly and laterally to provide lateral support and to prevent a person's head from rolling to the side, if the user should doze off.

Abstract: A power supply for use in a computer terminal capable of providing a plurality of direct voltage signals to the computer terminal logic system while isolating this logic circuitry from the line voltage is disclosed. A high frequency power supply transformer and associated circuitry provides the various direct voltage signals to the computer terminal logic system and provides isolation between the line input and logic circuitry. Parallel isolation is provided by a horizontal sync coupling circuit which is driven by the logic system and which, in turn, synchronizes the horizontal deflection system. The direct voltage signals provided to the logic supply system are both scan- and pulse-derived from the horizontal sweep signal permitting various computer terminal systems to be operated by display-derived power output signals.

Abstract: Dynamic focus voltages for a CRT are obtained by utilizing the combined parabolic conversion wave shapes for control of the focusing electrode to provide sharp focus at all points in the raster. A current source is coupled to the focus divider chain and the conversion wave shape controls the current in the divider chain by controlling the resistance in a transistor. No high voltage capacitors are required since the dynamic voltages are coupled into the chain near the low voltage end.

Abstract: An oversize, heavy duty beach towel is provided with sealable pockets at one end. The pockets are located so as not to interfere with the use of the towel for drying oneself off after swimming or for reclining. The pockets are designed to enclose various items that may be brought to the beach. One of the pockets is larger than the others, and is located at the middle of one end of the towel to facilitate its use as a pillow when filled with soft, bulky material. Waterproof zippers and linings protect the contents of the pockets from moisture. The towel unit includes a removable handle to be used for retaining the towel and its contents in a convenient package when the towel is rolled or folded.
