Abstract: A process and multistation apparatus for injection blow molding a thermoplastic material to form a blow molded container having an integral injection molded handle is disclosed. The process and apparatus feature an injection mold which is closed to form an injection mold cavity with a contiguous injection mold handle cavity. A preform pin is inserted into the injection mold cavity through a preform carrier to form a preform recess into which hot thermoplastic is injected to form a hollow preform having a solid injection molded handle. After cooling the thermoplastic preform the preform pin is withdrawn and the molds are opened. The injection formed preform may be optionally heat treated prior to the preform being enclosed within a blow mold. The blow mold forms a cavity having the final desired container shape and a cavity into which the handle is enclosed.

Abstract: An improved hollow plastic container which is blow molded from an injection molded preform is disclosed. The container has an integral injection molded handle which handle is attached at only one point to the container. The injection molded handle is formed contemporaneously with the formation of the injection molded preform.

Abstract: This invention relates to a marble shooter device which features: a frame having two elongated sides attached together at one of their ends in a spaced-apart relationship by a front end frame piece and attached together at their outer ends in spaced-apart relationship by a rear end frame piece; a barrel mounted to the end frame pieces and between and substantially parallel to the elongated sides, the barrel having a loading port on its upper side for loading the barrel with a marble and a barrel trigger notch in the top of the barrel and rearward of the loading port, and a pair of slots on opposite sides of the slot and rearward of the barrel trigger notch; a striker which is fittable within the barrel which has at least one striker trigger notch on its upper side; a power source attached to the frame and the striker to propel the striker towards the front end of the barrel; a trigger attached to the frame, the trigger extending into the trigger notch to contact and hold the striker in a rearward position by

Abstract: The lighter of the present invention includes a handle for grasping by the user connected to a chamber for holding a disposable lighter. The chamber has a trigger mechanism connected thereto for depressing the fuel releasing element of the lighter. The chamber also has a hollow metal rod extending therefrom and aligned with the fuel supply element of the lighter in such a manner as to convey the fuel from the lighter to the end of the rod.

Abstract: A two-piece nozzle for use on hand actuated pump dispensers is disclosed. The nozzle features a tubular member, which may be a part of the main body of the pump, having a circular, planar face at its terminal end. A hollow bore extending through the tubular member and the hollow face is in liquid passage communication with a recess in the planar face. A cap is rotatably mounted to the tubular member and has an end wall with a planar inside surface which will form an interface with the circular planar face of the tubular member. Radially displaced from the center axis of the circular skirt is a dispensing orifice which is registerable with the recess present in the planar face of the tubular member. A sealing boss surrounds the dispensing orifice and bore to provide a liquid-tight seal with the planar face when the orifice is not in registration with the recess. Mounting structure is provided on the cap and tubular member for achieving a rotating mount of the cap to the tubular member.

Abstract: A grading and dozing attachment for a tractor including a blade located between the front wheels and the back wheels of the tractor, a carrying frame adapted to fit between the front wheels and the rear wheels of the tractor, the frame having a plurality of symmetrically disposed legs attachable to the rear axle of the tractor and a lifting mechanism connected to the tractor and the carrying frame for pivoting the carrying frame upwardly and downwardly about the rear axle, plates for adjusting the angle of the blade in a horizontal plane attached to the carrying frame by pins, and plates attached to the blade for adjusting the angle of the blade in a vertical plane.

Abstract: An artificial fishing lure which may be fished within aquatic weeds without the lure hooks tangling themselves in the weeds is disclosed. The lure features a lure body having a hollow portion into which an automatically actuated hooking mechanism is housed. The hooking mechanism has a pair of hooks which are mounted at their shanks to a pivot rigidly mounted in the hollow portion. The hooks are originally within the housing and are arcuately movable about the pivot so that the hook points are outside the hollow portion and facing forward. To achieve this arcuate motion, an elongated V-shaped spring is slidably carried within the hollow portion and is attached at its leg ends to the hook ends. These points of connection will assume a position rearward of the pivot when the hooks are in the retracted position and within the hollow portion. When the points of connection are moved forward of the pivot, the spring action causes the hooks to move arcuately outward in the outside position and facing forward.

Abstract: A device is disclosed for the packaging and dispensing of a hot-fill solid product such as solid antiperspirant. The device provides for product holding structure which will have selectively attached thereto a cover which will, along with the produce holding structure, provide a cavity into which the hot-fill product may be introduced. Also attached to the product holding structure is a handle. In use, the cover is removed from the product holding structure to expose the product so that it may be applied. The cover may have a structure on its outside surface for supporting the device in an upright position with the cover being at the bottom and the handle at the top. Alternatively, the handle may have supporting structure which will allow setting of the device down on the handle so that the handle is on the bottom and the cover is on the top.

Abstract: A lighted cassette holder for displaying and protecting cassettes is disclosed. The cassette holder features a plurality of cassette holding tracks which are diagonally convergent. The tracks are held by a support member which is attached to a base and a top plate. Electrical lighting is provided adjacent the top plate. Movable dust shields are mounted between the base and top plate to protect the cassettes from dust accumulation.

Abstract: A filter box for filtering trash from sand is disclosed. The box features a rectangular portion and a trapezoidal portion. The trapezoidal portion is enclosed by tapered sidewalls and an overlying trapezoidal top wall to form a funnel. The rectangular portion has upwardly projecting sidewalls which connect with the tapered sidewalls. A screen is fitted within the sidewalls of the rectangular portion and is utilized to filter, from sand, any trash that may be present. The filtered sand is then replaced into the receptacle from which it came by pouring it through the formed funnel of the filter box of this invention.

Abstract: A method and apparatus for determining the location at which a string of pipe is stuck in a well bore. The apparatus has two relatively movable sections and an electrical sensing device for determining relative movement of the two sections which produces a signal representing the movement. The electrical sensing device has a wiper arm adapted to be displaced with a longitudinal deformation of the pipe string and with angular deformation of the pipe string.

Abstract: A thermoplastic tamperproof closure for fitment to a container is disclosed. The container has a threaded neck and an outwardly extending flange beneath the neck threads. The closure features a top wall with an annular sidewall downwardly depending therefrom and having about its inside surface a thread for cooperation with the container thread. Attached to the sidewall by a plurality of spaced apart, non-fracturable ribs is a fracturable band which will fit in a position of intereference under the container flange. This fit is achieved by applying heat to the ribs and band, after the closure is fitted to the container, causing the band and ribs to shrink to the position of interference.
