Abstract: ABSTRACT OF THE DISCLOSURE     A method of packaging an object in flexible thermo-plastic film material comprises moulding the film by differential pressure in a die cavity to form in the film a recess having the same surface area but a different contour to that of the object, the film then being re-shaped after removal from the die cavity to form a container having a contour corresponding to that of the object, the object then being deposited in the container which is closed by another film sealed around the mouth of the container.  The parts of the recess corresponding to corners and edges of the object have a larger radius of curvature, prior to re-shaping of the film, then the radius of curvature of the corresponding edges or corners of the object, so that the stretch of the film during the moulding operation is less than if the film was moulded in a die cavity in the shape of the object.

Title: Frequency synthesizer with rom controlled divider and  display
Inventor: BECKMANN ROBERT M
IPC: G06F3/14
Filed: 1979-02-05
Granted: 1981-09-01
Abstract: ABSTRACT           A frequency synthesizer is disclosed in which a single read only memory (ROM) is utilized to directly control programmable frequency dividers in a phase locked loop while also directly controlling the excitation of seven segment visual digital display modules. During the tuning of the frequency synthesizer, an enable circuit disables the programmable dividers while altering the input signals to the read only memory such that direct drive signals are produced by the output of the read only memory which alternately excite two separate seven segment displays modules.           After the tuning operation is completed, the enable circuit alters the input signals to the read only memory, simultaneously enables the programmable dividers, and effectively disables the digital display modules such that they hold their previous visual displays.

Abstract: ABSTRACT OF THE DISCLOSURE           Methods and apparatus for steam sterilization in which goods are conditioned by removing air and heating to a desired temperature in a sealable chamber.  Pressure change in the chamber is monitored and employed to control conditioning.  The goods are subjected to a plurality of controlled cyclic pressure pulses below a predetermined supra-atmospheric pressure level by alternate evacuation and vapor pressurization of the cham-ber.  The cyclic pressure pulsing is made responsive to load characteristics which are determined by monitoring pressure change in the chamber.  In a specific embodiment, air is flushed from the chamber initially by the injection of steam simultaneously with evacuation; the evacuation phase of each pulse continues until both a predetermined time has lapsed and a predetermined vacuum level has been attained; and, the steam pressurization phase of each pulse is continued until a fixed pressure related to sterilization temperature is reached.

Abstract: ABSTRACT        A fluid flow monitor for use in a steam flow line and comprising a chamber (1) in which condensate can collect and a single baffle (5,50) between an inlet (2) and an outlet (3) of this chamber. The baffle is disposed such that a steam flow induced pressure drop at the chamber outlet results in rise in condensate level on the outlet side of the baffle and corresponding fall on the inlet side.  The monitor further comprises means for detecting change in condensate level constituted by a single electrode (8) extending into the interior of the chamber, this electrode being electrically insulated  from an electrically conductive area (9) exposed to the collected condensate and positioned such that in use change in condensate level to a predetermined extent breaks an electrically conductive path from the electrode via the condensate to the conductive area.            The need for sight glasses which are easily dirtied and require skill in use is avoided and the monitor described is of simple construction.

Abstract: ABSTRACT         A sampled data servo positioning system employs an actuator to move a member between a current and a target position.  Incremental position feedback is provided only at sampling times.  The system employs a model responsive to a velocity related input signal to produce a continually available model incremental position signal.  Phase com-paring means indicates phase differences between the model and sampled position signals at the sampling times.         The system has two operational configurations in the first of which a source of saturation control signals is connected to the actuator to cause maximum acceleration or deceleration thereof.  In this first configuration, the model is forced to track the actuator motion by means of feedforward plus feedback control.  The feedforward signal represents actuator performance while the feedback signal is the position signal phase difference.  In the second operational configuration, a velocity profile signal is applied to the model and the actuator is forced to track the model by means of feedforward plus feedback control.    The feedback signal is again the position signal phase difference but the feedforward signal is a predetermined signal representing the desired actuator current to execute the velocity profile.  The sampled data servo positioning system may be the access motion control system of a sector servo disk file.
