Abstract: Abstract An improved process for the for the formation of alumina-containing fiber is described.  The process utilizes alumina having an alpha crystalline phase content in the range of from 5% to 60%, preferably 5% to 35%, as compared to the alpha alumina contents of 75% to 90% of the prior art materials.  Use of the low alpha crystalline phase content alumina permits substantial increase in the melt rate of the alumina-containing composition and thus increases production of fiber without any significant deterioration of other processing parameters or properties of the finished fiber.

Abstract: SPEAKER CROSSOVER NETWORKS          ABSTRACT OF THE DISCLOSURE The invention comprises improved electroacoustic audio speaker cross-over networks. The improvements comprise both the addition of various passive elements and a novel inductively coupled circuit configuration. The improvements are applied to low pass and nigh pass networks and combinations thereof. In the preferred embodiments a separate electrical circuit is inductively coupled to the filter network. The physical configuration of the separate circuit can be easily adjusted to counter variations in individual speaker performance parameters. Thus, production variations in speakers from the same manufacturer or among the products of different manufacturers can be overcome and a better matching of speakers provided. In the simplest embodiment the separate inductively coupled circuit comprises a copper ring placed within an inductive coil of the filter. Adjust-ment is accomplished by adjusting the physical location within the coil or by small changes in the physical dimensions of the ring.

Abstract: Abstract My invention is a power-driven therapeutic machine designed to replace the three to five therapists needed, until now, to impose passive homolateral crawling, passive cross-pattern crawling and cross-pattern creeping exercises on brain-damaged patients.  The weight of each patient is born by the benches and head-cradle of the machine while the limbs and head are moved in rythm.  All of these movements are done for them while they are in a prone position.  There are three variables for this type of therapy; intensity, duration and frequency.  These may be controlled to a large extent by this invention.

Abstract: ELECTRONIC INTERRUPTER     ABSTRACT OF THE DISCLOSURE A circuit for controlling the intermittent application of a dc potential to a device, such as a striker mechanism for a gong, having a mem-ber reciprocally moveable between rest and active positions. The recipro-cating member shunts snd unshunts a capacitor when the member is in its rest position and moved away therefrom, respectively. While the capacitor is shorted, and during its charge time, dc power is applied to the device.          When the capacitor is charged to a predetermined potential, dc power is disconnected from the device thereby allowing the reciprocating member to return to its rest position to shunt the capacitor and initiate a new cycle of operation. The system is substantially independent of mechanical character-istics of the device and the current interrupted or made by the contact pair may be at least an order of magnitude less than the peak current in said device.

The bypass or shunt switch of such group of power converters subsequently receives an opening command.          The control pulses, after accomplishment of opening of the bypass or shunt switch are shifted  in accordance with a predetermined linear ramp function in the rectifying range and thereafter the control pulses are delivered by means of a pole current regulator.  The placement into operation of a power converter operating in the inverting mode is accomplished in a similar fashion.  Reactive power swings or fluctuations between the network and the power converters are avoided.

Abstract: MULTI-CHAMBER TEMPERATURE COMPENSATED PNEUMATIC COUNTERBALANCE              ABSTRACT OF THE DISCLOSURE           A pneumatic, piston/cylinder counterbalance in which the counterbalance force is obtained by differential pressure across the piston and in which the force changes due to temperature are compensated by use of a variable volume cylinder having one or more auxiliary chambers separated by walls, each including a temperature responsive bi-metal disc valve normally acting as a check valve permitting flow into the auxiliary chambers but pre-venting flow out of the chambers except when the temperature drops to a predetermined value.  In the multiple auxiliary chamber embodiment, flow into and out from each chamber is controlled by an associated bi-metal disc valve responsive to successively lower temperatures to enable a more linear stabilization of force output regardless of temperature.

Abstract: ABSTRACT OF THE DISCLOSURE            The apparatus includes a fluid-tight housing oscillated about a vertical axis, the housing containing a central deflector separating the housing into an upper chamber and a lower chamber.  Baffles are provided in both chambers, above and below the deflector.  The upper baffle directs the incoming slurry radially outwardly in a torical path, throwing the particulate material toward the periphery of a housing in the first separation zone the particulate material passing in a gravity induced flow, through the annular passageway into the lower hopper where the relatively lighter and heavier constituents are then separated and separately discharged from the housing.  A ring dam formed in the second baffle provides a recess into which the lighter constituents overflow where they are reunited with the liquid flow path and thus discharged from the housing.  An aspirator removes air automatically from the top of the chamber.  The method carried out by the apparatus is claimed.  In a second embodiment the slurry is introduced tangential in the upper chamber and radial paddles or baffles arrest the whirlpool thus created, so that during the first portion of operation the slurry is subjected to centrifugal action and subsequently to settling action.  In other forms of the invention, recirculating closed systems are provided for re-circulating the fluid medium.  Also, the flow rates of the fluids and solids or particulates are independently adjustable by various means.  The slurry is formed from fluid particulate material.  Either gas (air) or liquid (water) is used as the fluid medium and finely divided solids such as gold ore is used as the particulate material.

Abstract: Abstract of the Disclosure A temperature control system for a building has a temperature responsive means or thermostat in the space for controlling a temperature conditioning apparatus furnishing temperature condition medium to the space. A time control apparatus provides for a reduction or deviation of the space temperature during certain time periods for the purpose of energy conservation and/or comfort.  The space temperature is restored to the normal temperature by a pickup operation.  The magnitude of temperature setback initially selected or to be maintained during the setback time period is automatically adjusted by responding to the actual building heat load, so as to keep the time and heating capacity needed to restore the space to the normal temperature within certain limits.
