Abstract: A process, system and pressure chamber for the automated sterilization of articles, particularly medical or dental instruments is disclosed, which is simple to use and economically efficient by comparison with conventional autoclaves and steam sterilizing system. Steam is generated by the pulsed injection of a controlled quantity of water into a heated boiler whenever it runs dry. The boiler is coupled in a closed-loop system to a relatively small pressure chamber in the form of a cassette that is readily inserted and removed from a holder comprising means for connecting the chamber to a steam inlet conduit and a venting conduit, the latter being closed off during pressurization of the chamber. By automated monitoring of the boiler and chamber temperatures, conditions in the chamber are measured and the boiler and valves in the system controlled to effect a sterilization cycle.

Abstract: A pacemaker may be implanted with equal facility on either side of a patient's chest without causing torque in the lead wires and avoiding unwanted local muscle stimulation. In one embodiment, the casing of the pacemaker is provided on opposite sides with a removable tab that covers an indifferent electrode so that when the device is implanted the appropriate tab may be removed to expose the electrode facing the patient's chest cavity. In a second embodiment, a portion along the edge of the pacemaker is left exposed to serve as the indifferent electrode, again allowing the device to be implanted with equal facility on either side of the chest without torque in the lead wires. Furthermore, since the edge of the device is not facing toward the patient's pectoral muscles, the device avoids unwanted pectoral twitching.

Abstract: An above-ground secondary containment unit for storage tanks is comprised of a rigid base and upwardly extending side and end walls. Side cover shields are mounted to the top of the side walls by way of hinges and are intended to contact a side surface of the storage tank thus minimizing or preventing the entry of precipitation or debris into the unit while the tank is in place. End cover shields are mounted to the top of the end walls using a nut and bolt arrangement and slots in the shield allowing for lateral adjustment of the shields with respect to an end surface of tanks of varying sizes and configurations. These shields similarly minimize or prevent the entry of precipitation and debris into the unit. The walls of the unit are tapered so that one unit may be nested within another similarly shaped unit for convenient storage and to permit shipment of multiple units at the same time.

Abstract: A method and apparatus for the preparation of a wound roll of a web of material is provided. The apparatus utilizes a surface windup device for automatically introducing a core onto a primary lay-on roll, and automatically cuts the web so that it can be attached around a new core. A primary lay-on roll feeds the web of material onto the rotating core. The core is driven by a secondary lay-on roll. The differential in speed between the primary and secondary lay-on rolls controls the tension of the web as it is wound. This invention also incorporates a retractable cutting roll and knife assembly that moves into position to cut the web of material, assists in transferring the web of material to a new core, and then retracts to a position that does not hinder winding the new roll of wound material. The winder is also equipped with an apparatus that ejects the wound roll from the hold-down clamps as a new roll is automatically started.

Abstract: A glue gun includes a nozzle body and a replaceable nozzle cap. The body is mounted in a melt casting of the glue gun such that it is rotationally adjustable. Thus, a rotationally asymmetric nozzle cap is more easily used because the nozzle body can be rotated to correct misalignment of the cap due to differences in the orientation of threads holding the cap to the body.A preferred nozzle includes a plurality of openings that allows the application of several small beads. These beads can be pressed into a thin layer if delay tack adhesive is used.

Abstract: Volumetric metering equipment, especially but not exclusively for use in metering the volume of fluid pumped through one or more injectors by a diesel-engine fuel injection pump, having means which serve to cause the inertia of a moveable member, and/or a return force applied to a moveable member to reduce the time taken for a desired back pressure to be built up following a draining operation.

Abstract: A support bracket for protective railing may be adjustably positioned on a wall or other surface. The bracket is constructed such that when the bracket is loosely assembled, the placement of a rail segment on the bracket may be adjusted as desired within a limited range in one or more directions. After the placement of the rail segment has been adjusted, the component parts of the bracket are tightened to fix the rail segment in place. When assembled, the bracket forms a sealed unit with a smooth exterior that has a minimal tendency to collect dust, dirt and bacteria and that is easy to clean.

A floater provided in the artificial floating space has a buoyancy vessel part and a support part in which a floating person rides. The floating person enters the artificial floating space through a gate unit and rides in the support part of the floater for steering the floater for floating operation thereof in the artificial floating space.

Abstract: Apparatus for obtaining a desired tint, which apparatus uses a light source to provide a gamut of colours. The apparatus comprises wheel and paddle (34,60) which enable a tint to be obtained from such light in such a manner that the hue and saturation of the tint can be varied substantially independently of one another, whilst maintaining a given brightness. The invention extends to a method using such apparatus, and to equipment comprising a set of coloured filters, and also to a method in which a tint created by a combination of filters selected from a set of filters is varied, by removal, addition, or replacement of one or more filters of the combination, to match the selected tint, and finally to the making of lenses using such methods, and the lenses themselves.

Abstract: A grouting composition for sealing boreholes or other cavities comprising 90.0-99.99% water swellable clay and 0.01-10.0% gelling agent. The grouting composition is mixed with fresh water to provide an easily placed, low cost, low permeability sealing composition. A preferred grouting composition contains 98-99% sodium bentonite and 1-2% cement. In use 50 pounds of the preferred grouting composition is mixed with 27-38 gallons of fresh water to produce a grouting composition containing 13.7-18.2% solids and having a fluid density equal to or greater than 9.0 lbs/gallon with a Marsh funnel viscosity equal to or greater than 50 seconds.

Abstract: An injection site designed for use with a needleless syringe includes a housing placed in an infusion line and an inlet for engaging the syringe and conveying a fluid to be mixed with the infusate to the interior of the housing. A liner within the housing controls flow of fluid through the inlet by sealing the inlet when the pressure in the housing is equal to or exceeds the pressure in the syringe. The housing is made of two parts, each of which includes a flange. When assembled, the spaced flanges are on opposite ends of the liner, which is not directly attached to the housing, to limit movement of the liner to maintain its position in the housing.
