To accomplish this, the wheelchair tilting apparatus utilizes a base frame arranged for placement on a ground surface, the base frame pivotally mounting the rear end of a wheelchair supporting tilt frame assembly having an upstanding backrest member arranged to support the chair and occupant reclined thereagainst when the apparatus is in operative, tilted condition.

Abstract: An apparatus for the high-volume manufacture of assembled wall frame structures for use in the residential and commercial building industry is arranged to receive and support a pair of laterally spaced apart top and bottom plate members and move them longitudinally in indexed, stepwise increments through a stud-inserting and fastening station in which wall stud members are automatically positioned to engage and extend perpendicularly between the plate members at predetermined intervals therealong, whereupon the opposite ends of a stud member are secured to the opposite plate members by a fastening device, whereby complete wall frame assemblies may be quickly and efficiently made on a continuous basis according to desired specification as ordered and thence delivered to a construction site for erection.

Abstract: A deposit collecting and transporting security apparatus provides a deposit container arranged to be lockably mounted for receiving and collecting deposits from a depository outfeed apparatus. In order to remove the container for transport to a deposit processing facility, a container-closing lid panel is slid onto the container into position closing the confines thereof against access whereupon the lid panel is automatically locked in place against removal. Thus locked against removal, further slight sliding movement of the lid panel overrides and disengages a container mounting lock, thereby permitting the container to be removed from the depository for transport only after the lid panel has been installed and locked into operative position securing the confines of the container against access.

Abstract: Recovery of ethanol from the exhaust stacks of a bread-baking oven is achieved by passing the stack emissions through an adiabatic humidifier where the emissions are humidified to near saturation. The unevaporated water content of the humidifier is collected for separation of the ethanol content. The humidified emissions are passed from the humidifier to the vaporization chamber of a heat exchanger where the gas content of the humidified emissions is separated from the moisture content thereof, and the moisture content is collected for recovery of the ethanol content.

Abstract: A swimming exercising and training tether device includes an elongated tether line connected at one end preferably through a coil spring or other elastic, shock-absorbing member, to an anchor adjacent a wall of a swimming pool and at the opposite end detachably to the back panel of a harness worn by a swimmer. The attachment to the back panel is in the area intermediate the shoulders of the swimmer. Intermediate the ends of the tether line it extends freely through a loop or ring secured to the back panel of the harness in the area intermediate the hips of the swimmer. The loop or ring functions to raise the hips of the swimmer to the level promoting most efficient swimming posture in the water.

Abstract: An object or vehicle transporting dolly supporting one elevated object end comprising of a pair of mounting pads and transporting wheels each connected to a pair of vertically pivoting control arms which have also a vertical pivot connection to a center parallel control member which then can be fixed to a draw and steering control tongue. The scissoring control arms provide for handling multiple widths of objects. A frame connection rack or a wheel well for dollying of wheeled vehicles can be fixed to the mounting pad and can optionally swivel on the mounting pad. Articulation between the towing and towed vehicles force the tongue and control arms to direct the mounting pads and the trailering wheels to maintain a longitudinal alignment to the draw control tongue, even though they are in a fixed longitudinal position to the transport object causing king-pin type of steering with the swivelling at the mounting pad.
