Abstract: A collapsible walker that includes a front frame, a pair of side frames, and a pair of levers. The front frame has a pair of skewed surfaces. The pair of side frames are hingedly attached to the front frame and are parallel thereto when the collapsible walker is in the closed position and are perpendicular thereto when the collapsible walker is in the open position. The pair of side frames have notches therein with skewed surfaces, with the pair of skewed surfaces of the front frame being vertically movable in the notches. The skewed surfaces of the pair of side frames move relative to the pair of skewed surfaces of the front frame as the collapsible walker is achieving the open position, until such time as it achieves the open position in which the pair of skewed surfaces of the front frame and drop down in the notches and mate with, and abut against, the skewed surfaces therein so as to prevent relative rotation therebetween and further rotation of the pair of side frames in both directions.

The spokes and/or the ring are selectively movable relative to each other between a first position wherein the ring abuts with the end of the spokes preventing removal of the merchandise, and a second position spaced from one or more of the spokes to free the ends thereof, permitting removal of the merchandise.

Abstract: An elongated rod is journalled in a housing to reciprocate substantially vertical therefrom and has a cutting blade fixed on the tip of the lower end of the rod. A rotary motor is located at the upper end of the housing and is provided with an eccentric cam for converting the rotary motion into linear reciprocating motion.

Abstract: A pair of terminals is provided, each terminal being identical to the other and being formed of an insulating body having a plurality of electrical conductive contacts partially embedded therein. The frontal sections of the contacts are exposed from the surface of the body so that the terminals may be placed into frontal abutment with the conductive contacts in mutual engagement.

Abstract: A neck band for holding napkins, bibs and the like on the chest of the user. The neck band is formed of a strip of disposable material, such as paper provided with a tab of self-adhesive material at each end, by which the strip can be attached to the napkin, bib etc.

Abstract: A VCR player tape cartridge reinsertion device for automatically reinserting a conventional tape cartridge back into a tape input slot in a conventional VCR player after the conventional tape cartridge has rewound and been partially ejected therefrom so as to allow the conventional tape cartridge to automatically record continuously without the need for an endless tape. The device includes a platform, a motor, an upright shaft, and at least one arm. The platform is positioned in close proximity to the tape input slot. The motor is disposed in the platform and has a shaft that extends vertically upwardly therefrom. The upright shaft is vertically-oriented and operatively connected to the shaft of the motor for rotation therewith.

Abstract: A plastic flat bottom bag is provided with a handle, which is attached while the handle is flat against the surface of the bag and is directed downwardly toward the flat bottom.

Abstract: A hanging planter having a bowl shaped container and a suspension assembly is provided. The suspension assembly comprises a plurality of stringers the lower ends of which are attached to the rim of the container. The upper end of the stringers are joined together in a rim shaped hub to which is removably connected a hook so that the hook and stringer assembly are rotatable relative to each other.

Abstract: This invention relates to a vibration-type gyro apparatus for measuring an angular velocity using the Coriolis force exerted on a tuning fork. The tuning fork has two vibrational members symmetric about a Z axis. The two vibrational members vibrate along Z axis and are displaced along a Y axis by the Coriolis force. Each of the two vibrational members includes a cantilevered tabular member arranged along an XZ plane and has a shape symmetric about the center axis thereof. Electrode sections are formed on the two sides of the vibrational members, and electrodes are formed in the internal space of a casing at positions corresponding to the electrode sections. The electrodes are arranged by being deviated outward or inward of the center axis of the vibration members with respect to the electrode sections. Each of the electrodes is supplied with a displacement detection AC voltage and a control voltage from a detection and drive circuit.

Abstract: Retaining pin assemblies for use in releasably securing an excavating tooth or point to a mounting adaptor. Each pin assembly includes one or more holders insertable lengthwise in registering apertures in the adaptor and tooth and movable thereafter widthwise to cause interengagement. The holder and the apertures are provided with complementary portions. A locking member is inserted after engagement of the pin to fix the adaptor and tooth together.

Abstract: Individual sheets of paper currency or bills are conveyed in line in a path from a receiving inlet slot through a verification station and outputting verified currency through a storage slot. The verification station senses the value and authenticity of the currency and converts the value into a signal and thereafter moves the paper currency to the storage station where they are securely stacked one on top of the other.

Abstract: A fluid actuator for use in a fluid injector assembly including a piston arranged for reciprocation in a chamber, the piston including a connected plunger operating in an injection chamber. A control valve member is actuated to apply fluid to the chamber on opposite sides of the piston to reciprocate the piston and plunger. A fluid throttling arrangement is provided to decelerate the piston towards the ends of its stroke. The fluid actuator may also be associated with an engine valve assembly. A fluid actuated engine piston assembly is also described.

Abstract: A stack of light-deflecting elements are installed in a window. Each deflecting element has a solar ray inlet, a curved middle section and an end comprising a ray outlet into the room. Each element is rectilinear at the outlet end so that rays are dispersed and emerge from the light-deflecting elements in prisms of rays, the bottom edge of which is horizontal. The solar rays entering the light-deflecting elements are subjected to multiple total internal reflections at a different angle. The angle of the normal line of the deflector elements to the horizontal is selected so that the largest possible amount of sunlight can be captured and conveyed into the room to illuminate the room with a uniform, diffuse distribution.

Abstract: A method for the qualitative determination of the visible levels of glycol and/or formaldehyde at significant concentrations greater than 10 ppm (10 ppm-10,000 ppm range) in a water sample, in which the sample is treated first with periodic acid, then with iodide-thiosulfate and finally with acetyl acetone to yield a yellow color without the benefit of heat. This yellow color is visible to the naked eye and proportional to the amount of contaminants ethylene glycol, propylene glycol and/or formaldehyde present in the original water sample.

Abstract: In a method for quenching metal parts, a quenching chamber is provided in which the quenching oil is continuously supplied from below the steel parts and circulated upward through the parts in a laminar flow.
