Abstract: A security system for distributed computer systems with a central computer and remotely located interactive terminals. The security system includes a master security control processor (SCP) which is associated with the central computer, and one or more slave SCPs, each of which is associated with one of the interactive terminals. Clearance at several security levels is required before communications between one of the remote terminals and the central computer is authorized. The security levels are implemented after communications are established to maintain only authorized access to the central computer. One of several unauthorized access modes are implemented when an unauthorized interactive terminal or SCP is identified. All data communicated between the master and slave SCPs is encrypted for security.

Abstract: In the case of a pizza home delivery system, customer addresses and mapping information may be auomatically retrieved and displayed based on customer telephone number, and order data including an assigned order number may be imprinted on a label to be attached to each pizza container. Preferably, the system produces the order number in the form of a bar code on an adhesively backed label. Each driver may check out order for delivery by inserting his coded identification key at a bar code reader station and having the bar code labels scanned into the system, so that each order is assigned to a particular driver in a reliable and accurate manner. A voice synthesizer unit at the station can then remind the driver that the order includes beverages or more than one pizza container, and can advise the driver when the sum of the cash payments he has received for his deliveries exceeds a certain amount, making it advisable to deposit some of the accumulated cash before the next delivery.

Abstract: A method of converting a conventional lock set from one manufacturer's lock cylinder to another's is provided. The method includes provision of a universal doorknob or handle mountable, generally by means of adaptors, on any of a variety of manufactures of hardware systems. The universal knob includes means therein for mounting of a selected manufacture or design of lock cylinder. According to the method a tail piece member is provided, to translate motion from the lock cylinder to a drive mechanism of the hardware system being converted. Generally, according to the method each different design of lock cylinder will have a different universal knob design associated therewith. Further, each selected lock cylinder design will have associated therewith a set of tail piece members, one for each manufacture or design of hardware systems. As a result of the above, almost any type of hardware system can be readily converted to a system utilizing a universal knob and a selected lock cylinder.

Abstract: A fluid filled resilient bushing assembly for rotary vibratory motion control, particularly adapted for use in a joint between a motion inducing member and a base member, having an elongate outer rigid sleeve member, an elongate inner rigid member rotatable with respect to the outer rigid sleeve member and a resilient means interposed between the inner and outer members. The resilient means defines at least two spaced chambers interconnected by an elongate restricted passageway filled with incompressible fluid. The bushing assembly further has a pressure differential inducing means creating a differential in the fluid pressure of the chambers due to the rotary motion of the inner rigid member to permit contraction of one of the chambers, expansion of the second chamber and fluid flow therebetween providing damping of the rotary vibratory motion.

Abstract: A subterranean well casing float tool is comprised of a tubular metal housing which is securable to a well casing conduit. Varing means are implaced within the housing, with substantially all of the components of the valving means, save a biasing means, are thermosetting. The valving means has a thermosetting frame and valve head and valve seat means relative to the frame. A biasing member, such as a compressed spring is used for urging the valve head toward the valve seat to a closed position. A compartment including the valve head is provided for enclosure around the biasing means when the valve head is moved fully away from the valve seat to protect the spring from errosive turbulent fluid flow when the valve head is in the open position relative to the seat. The valving means is directly secured to the housing by means of thread members having profiled shear surfaces such that the shear area of the valving means is substantially greater than that of the metal housing.

The service override switch is interconnected with the normal operation switch so that both switches cannot be closed at the same time.

Abstract: A patient monitoring unit is used to follow the actual changes in a patient's weight during the course of a surgical procedure. A patients' fluid inventory is vital to the patients' well being and any significant additions to or losses in body fluids are very significant in the proper management of the patient during surgery. Real time changes in a patient's weight are monitored throughout the surgical procedure. A weighing system utilizing strain gauges or other transducers is built into the operating platform and the output from the transducers is communicated into a computer controller. Angle sensors are provided to measure the tilt at which the operating table may be placed thereby causing an apparent change in weight. The apparent weight change is corrected to the true weight. In the event various portions of the operating table are individually articulated, separate weighing systems and angle sensors are provided for each articulated portion.
