Title: Adjustable bulkhead
Inventor: GUINS SERGEI G
IPC: B60P7/14
Filed: 1979-04-24
Granted: 1981-12-22
Abstract: ABSTRACT OF DISCLOSURE The present invention relates to an adjustable bulkhead for pre-venting the movement of lading within a lading carrying vehicle, such as a railway car, and more particularly, relates to a mechanical bulkhead having a structural frame member adapted to be mounted in a stationary position, with one or more expandable panels connected to said frame member by clevis linkages which are operated by one or more hydraulic cylinders. By the use of an air-operated hydraulic pump fed by a constant volume air reservoir of a size chosen so that as the bulkhead expands the pressure of the air supplied to the hydraulic pump, and thus, the oil pressure in the hydraulic cylinder, will decrease as the natural mechani-cal advantage of the clevis type linkage comes into play, a substantially uniform force can be kept on the lading regardless of the amount of the expansion of the bulkhead.     The use of the hydraulic cylinder permits a near instant response to the movement of the lading, either in the horizontal or vertical direc-tions with substantially instantaneous expansion of the movable bulkhead panels to take up slack and to prevent the development of voids that were present with the old air bag bulkhead systems, such voids being primarily responslble for cargo damage. The provision of a check valve in the hydraulic line also prevents any backward movement of the panels, and thus, the present invention provides a bulkhead which can initially expand to compress a lading, will maintain a uniform force on the lading, either in a horizontal or vertical direction and will quickly take up any slack which develops in the lading, but which will not retract until the operator desires it to, and thus, substantially eliminates the possibility of any damage to the lading being carried from having voids develop in the lad-ing due to quick starts and stops or bumps of the vehicle, into which cargo can fall and be crushed by further motion of the vehicle.

Abstract: METHOD AND APPARATUS FOR REMOVING COMBUSTIBLE MATERIAL FROM METAL SCRAP                   Abstract of the Disclosure A method and apparatus for removing combustible material from metal scrap.  The apparatus includes an inclined rotating retort, and scrap metal containing combustible material is fed into one end of the retort and as the scrap moves through the retort the combustible material is burned from the scrap.          The retort is spaced within an outer refractory housing to provide an annular chamber therebetween, and the chamber is divided into two or more zones.  Located within each zone is a fuel burner and a cooling air inlet.  The temperature is sensed in each zone, and if the temperature falls below a preset minimum, the burner in that zone is operated, while if the temperature in the zone exceeds a pre-set maximum, cooling air is supplied to that zone to thereby maintain the temperature of the scrap metal within predetermined limits.

Abstract: "CONTROL CIRCUIT FOR PROTECTING VACUUM CLEANER MOTOR FROM JAMMED BEATER BRUSH DAMAGE"              ABSTRACT OF THE DISCLOSURE         A control circuit for effectively preventing damage to the blower or fan motor of a vacuum cleaner which could otherwise result from a jammed condition of the beater brush thereof.  The control circuit effects discontinuation of the energization of the motor in the event the rotational speed of the beater brush drops below a preselected speed.  The dis-continuation of energization may be effected by the control a preselected period of time after the speed drops below the preselected speed.  An indicating device may be provided for indicating such discontinuation of energization.  A second indicating device may be provided for indicating a reduction in speed of the beater brush less than that sufficient to cause discontinuation of the energization but sufficient to warrant warning the user that a partial jamming of the beater brush has occurred.  The control may be arranged to require manual operation of the operating switch of the vacuum cleaner to the "off" condition and subsequently to the "on" condition to re-energize the motor subsequent to such discontinuation of energization.  The control includes means for causing the energization of the motor in the event the motor does not come up to a preselected speed within a preselected period of time after such operation of the control switch to the "on" position.  The speed of the beater brush may be sensed by a Hall effect sensor responding to magnetic pulses from a magnet rotatable with the beater brush.

Abstract: ABSTRACT OF THE DISCLOSURE        The present invention relates to the manufacture of fibrous wool by the rotary process.  In the rotary process heat softenable material, such as molten glass, is supplied to a centrifuge wherefrom streams of the heat softenable material emanate and are acted upon by a fiber attenuating high velocity gaseous medium located about the periphery of the centrifuging means.  A cylindrically shaped veil of high velocity gases having attenuated fibers contained therein flows axially away from the centrifuging means to a suitable collecting means.          Improved method and apparatus are provided for distributing the entrained fibers upon the collecting means.  The cylindri-cally shaped veil is intermittently acted upon by finite sheets of high velocity gas thereby interrupting the otherwise columnar flow of the cylindrical veil and establishing diverging flows of fibers.  There are preferably a pair of oppositely directed pulsating sheets each having modulated progressively ascending and descending pressure wave forms.  By the intermittent action of the gaseous planes upon the cylindrical veil a randomly uniform distribution of fibers upon the collecting means is realized.

Abstract: PULSE WELDING PROCESS            ABSTRACT OF THE DISCLOSURE    A gas-shielded, metal-arc, pulse welding process which comprises establishing an arc with a consumable metal electrode in a gas-shielded environment.  A direct current in the range of from about 15 to 80 amps is applied to the electrode and pulsated at a frequency of from about 5000 to 25,000 pulses per second to a first maximum amplitude of from 100 to 125% of the minimum current required to produce a spray transfer of metal from the electrode.  The pulsating current applied to the electrode is cyclically increased at a frequency of from about 90 to 400 cycles per second to a second maximum amplitude of from about 150 to 600% of the minimum current required to produce a spray transfer of metal from the electrode and is maintained at the second maximum amplitude for a time within the range of from 5 to 50% of each cycle.  The process is particularly applicable to automatic welding processes wherein the weld must be accomplished out-of-position.  In accordance with the present invention, the deposition rate is greatly enhanced in such a process without any detrimental effect on the quality of the weld.
