Abstract: Separating volatile impurities from AlCl.sub.3 by supplying impure AlCl.sub.3 into a molten salt bath of a gas separation compartment in an electrolysis cell. The impurities are removed from the compartment and molten salt bath containing dissolved AlCl.sub.3 is carried under a partition into a chamber where the AlCl.sub.3 is electrolyzed. In a preferred embodiment, desublimation is avoided by supplying AlCl.sub.3 to the bath as a gas rather than in solid form.

Abstract: A gimbaled cup supporting device for holding cups in a level position in a moving vehicle while at the same time isolating the cup from shock and vibration transmitted from the moving vehicle to the support mechanism. A shock absorber is described in which the central portion supports a collar and shaft attached to the cup holding mechanism and an annular ring portion displaced from the central portion is attached to a supporting shaft that is removably attached to the supporting vehicle. The rubber shock absorber isolates the supporting shaft from the gimbaled cup supporter while supporting it in the conventional manner.

Abstract: A resistance heating element is formed in a spiral pattern to a spherical radius to provide conductive heating for a wok. The resistance heating element is supported by a support which accommodates the spherical surface of the heating element. The heating element can be for either plug-in or permanent installation.

Abstract: The blower is made separate from the rest of a self-ventilated range and is installed prior to the installation of the range. The blower can be selectively mounted for through-the-wall or through-the-floor discharge and is located so that the hole in the wall or floor misses the studs or joists, respectively. After the blower is installed, the self-ventilated range is set in place over the blower and the blower is connected to the plenum by means of a flexible pipe. In this way the plenum can be made thinner providing more room for the oven cavity.

Abstract: A modular induction cooktop cartridge contains a fan which is interlocked with the panel switches so that whenever an induction unit is operative, air is drawn into the cartridge to cool the solid state electronic components. Air is exhausted in a high velocity discharge to minimize recirculation.

A plurality of tower assemblies are supported on the upper and lower tracks for longitudinal movement therealong. Each tower assembly includes a flexible tension member adapted for securement to a vehicle positioned between the side members and a power source for pulling the tension member toward the tower assembly to thereby straighten the vehicle. The track supporting frame includes a superstructure above the upper track and a plurality of upper pulleys adjustably mounted on the superstructure whereby each tension member may be trained about one of the upper pulleys for exerting a pulling force on the vehicle from an elevation above the upper track.

Abstract: A typewriter correction tape cartridge for holding and feeding correction tape for a correcting typewriter is improved by the addition of a beam spring cantilever supported such that one end of the beam spring wipes the correction tape onto the takeup spool. This will act to eliminate bubbles, wrinkles and crimps in the tape as it is placed in a new convolution on the spool and will thus reduce the outside diameter of the ultimate disc of used tape. The advantage of this spring is that a reduced size cartridge may be used while utilizing the entire volume of tape supplied on the supply side of the cartridge and, secondly, a more reliable takeup is accomplished due to the elimination of irregularities in the takeup disc.

Abstract: In a typewriter ribbon cartridge, it is necessary to maintain tension on the span of ribbon extending outside the cartridge to prevent tangling and to insure high print quality during machine operation. One technique for insuring that adequate tension is maintained is disclosed herein as an anti-backup back check device. Connected to the takeup spool of the ribbon cartridge is a disc member supporting thereon a pair of thin flexible resilient arms with outwardly oriented pointed ends. These ends formed in the shape of points engage ratchet teeth formed around the interior surface of a cylinder. The cylinder is formed as a part of the ribbon cartridge and, thus, is permanently positioned and fixed with respect to it. As the takeup spool disc and arms are rotated by the ribbon feed mechanism, the arms will flex and permit a rotation of the disc and takeup spool with a minimal drag force.

Abstract: A anti-detonation safety device for use in a bulk handling system transporting explosive powder. The device comprises spaced inlet and outlet members and, disposed therebetween, a plurality of interconnected planar panels defining a cruciform chamber, the wings of which each include a top panel, operable in response to an increase of the pressure in the chamber, to provide for venting the same.

Abstract: In a typewriter, a ribbon is contained within a cartridge which is in turn placed upon the ribbon mechanism support of the typewriter. The cartridge is maintained rigidly clamped to the support but readily releasable by means of operator actuation of a release lever. The cartridge may either be a single cartridge or may be stacked such as where two cartridges are utilized together, one containing a print ribbon, the other containing, for example, a correction ribbon. The cartridge containing the print ribbon is provided with a bottom plate or surface which is formed to define an aperture therein for the admission of a clamping member attached to the support. The clamping member is inserted into the aperture and then caused to rotate about its axis a part turn at which point the clamping member engages an inclined surface on the interior of the cartridge causing the cartridge to be wedged downward against the support.

Abstract: A recoil simulator is disclosed in which one end of a flexible cable is ached to a weapon and the other end to a system comprising a rotating shaft and a clutch. As the trigger of the weapon is pulled a signal is produced which activates the clutch. The clutch creates a sudden pull on the end of the flexible cable simulating recoil.
