Title: Injection moulded containers for foodstuffs
IPC: B29C45/14
Filed: 1971-05-12
Abstract: A container is formed by injection moulding a circular lip to which is attached a vertical element which holds in position a single sheet of flexible material which forms the vertical wall whose diameter decreases towards the base which is also part of the injection moulding, the sheet being welded along a rib which joins the mouth and base. The moulding may include a number of vertical ribs of which one constitutes the weld line. Axial ribs may bifurcate as they rise from the base. The transverse section may optionally by polygonal. The injection moulded portion of the container is of conventional material e.g. polyethylene or polypropylene, but the flexible sheet material is one having a low percentage of residual monomers such as biaxially oriented polystyrene. Due to the use of sheet material of low monomer content the container is suitable for use with foodstuff.

Abstract: Abstract A pair of similar conductivity transistors operated at substantially the same temperature T are connected as a current divider.  A common terminal to which their emitter electrodes are each connected receives an input current to be apportioned between the emitter-to-collector paths of the transistors, these separate currents flowing to respective branch terminals at the respective collector electrodes of this transistor.  The base electrodes of the transistors are connected to opposite ends of a resistive element.  A current responsive to T is caused to flow through the resistive element to cause a potential drop substantially proportionally responsive to T between its opposite ends, biasing the transistors relative to each other so as to apportion the input current to the branch terminals in an invariant ratio.  The means for developing the temperature responsive current may include a current regulator comprising a regenerative feedback loop connection of a pair of current amplifiers, one of which exhibits decreasing gain with increased level of current supplied to its input circuit.

Abstract: Application for Patent of Ronald W. Russell for OFFSET ADJUSTMENT CIRCUIT                  ABSTRACT OF THE DISCLOSURE       An offset adjustment circuit for a differential am-plifier includes a current source connected in series with a resistor for establishing a biasing voltage for a pair of field effect transistors (FET) having variable resistors in their biasing circuits.  These FET's are connected to intro-duce currents respective connections between an input stage and a second stage of the differential amplifier.  The dif-ference of the currents supplied by the FET's divided by the transconductance of  the input stage of the differential amplifier corresponds to an offset which remains fixed with changes in temperature.  The offset introduced by the FET's, as determined by the adjusted values of the resistors in their biasing circuits, may be in opposition to the offset of the differential amplifier to either reduce it partially or com-pletely, or it may be additive to the offset of the differ-ential amplifier, as desired.

The AGC circuit produces a constant amplitude output signal so long as the amplitude of the input signal exceeds an adjustable reference voltage applied to the peak detector.  The reference voltage may be changed to change the range of input voltages resulting in a constant-amplitude output.          The AGC circuit responds almost instantly to control a sudden increase in input voltage.

Abstract: TITLE:  DRAWBAR ASSEMBLY                         Abstract of the Disclosure A drawbar assembly for transporting three point hitch imple-ments in an elevated or lowered condition by a single point connector towing vehicle.  The assembly is wheel supported and mountable between the connector of a towing vehicle and the three point connectors of a three point hitch trailing unit such as a plow or other farm implement. The three point connectors are movably mounted relative to a central supporting framework.  A jack assembly and appropriate linkage inter-connect the three point connectors with the framework to enable movement of the three point connectors and attached implement between an elevated carrying position and a lowered operating position.  The jack assembly is operated through provision of conventional accessory drive units provided on the towing vehicle.  In an alternative embodiment, a tongue load relieving mechanism is also provided, operatively connecting the implement and tractor to reduce the load normally transferred to the hitch members through the tongue of the drawbar assembly.  Shock loads, received when the implement is in the elevated condition, are dampened through the stabilizer assembly.  The drawbar assembly pivots about the axis of a pin near the tractor drawbar to avoid binding the tractor and drawbar hitch members together.

Abstract: ABSTRACT OF THE DISCLOSURE          A single pressure sulfur hexafluoride circuit inter-rupter is contained in a bottle or elongated, cylindrical housing filled with gas under moderate pressure.  The bottle contains arcing and main contacts arranged generally along the axis of the bottle and arranged to separate from one another in the vicinity of a pair of spaced, conductive rings fixed relative to one another, and which serve as arc runners.  Each of the rings is connected in series with a respective coil which is wound on the axis of its respective ring and which encircles the cooperating contact and conductors therefor.  The coils and the conduction rings create a magnetic field which spins an arc drawn between the spaced short-circuited rings through the sulfur hexafluoride gas, thereby to extinguish the arc. Each short-circuited ring and its respective coil are fixed relative to one another and are contained within a common insulation body in order to withstand the high electrodynamic forces created between the rings and coils during high current interruption. A small, low capacity puffer cylinder is connected to one of the moving contacts in order to produce at least a limited amount of gas motion through the arc space between the open contacts and the fixed rings when the contact separate.  The arcing contacts are arranged to have a blow-off path directed to cause an arc drawn between the contacts to transfer to the spaced conductive rings.  In one embodiment of the invention, only a single coil is used to produce a magnetic field for spinning the arc between the spaced rings.  The interrupter structure is useful in connection with a vacuum dielectric medium.
