Abstract: A frame for a portable sprayer having an interlocking joint for securing sections of a frame on opposite sides of a tank. The interlocking joint facilitates attachment and detachment of tanks with respect to the frame, as well as securing a telescopic handle relative to the frame. An extension rib prevents the tank from tipping-over.

Abstract: A release mechanism is provided for a portable sprayer having a pump unit removably connected to a fluid tank. The release mechanism provides locking for the connection between the tank and the pump unit. Moreover, the release mechanism unlocks the connection between the pump unit and the tank, and operates in conjunction with a pressure relief mechanism to concurrently de-pressurize the tank to ease disconnection from the pump unit. Further, the compass of the pressure relief mechanism also serve to automatically relieve pressure when the pressure in the tank exceeds a predetermined threshold level.

Abstract: A cutting module and a cutting element which fits within the cutting module are used to remove polymer, e.g. insulation or a conductive polymer composition, from the first and second electrodes of the cable at the end of the cable in order to make electrical connection from the electrodes to the first and second contact members of an electrical plug. Present within the cutting module are first and second electrode-contact sections positioned on the concave arcuate inner surface of the wall of a cavity in the cutting module. The electrode-contact sections can be electrically connected to the first and second contact members. The cutting element comprises a cutting wedge which has (a) a convex arcuate outer surface which complements the inner surface of the wall of the cutting module, and (b) piercing means suitable for penetrating the polymer.

Abstract: An electrical plug for connecting an electrical cable such as an electrical heating cable to an electrical power outlet. Contained within the housing of the plug are first and second contact members which comprise a first prong and a second prong, respectively, each prong being suitable for insertion into a socket of an electrical power outlet. A cutting module and a cutting element which fits within the cutting module are used to remove polymer, e.g. insulation or a conductive polymer composition, from the first and second electrodes of the cable at the end of the cable in order to make electrical connection from the electrodes to the first and second contact members. Present within the cutting module are first and second electrode-contact sections positioned on the concave arcuate inner surface of the wall of a cavity in the cutting module. The electrode-contact sections can be electrically connected to the first and second contact members.

Abstract: An exercise device provides resistance to flexion or extension of the arms or legs. The device is worn about the knee or elbow and has a first framework which is secured about the upper portion of the limb and a second framework which is secured about the lower portion of the limb. Struts protrude toward the joint from the upper framework and from the lower framework, and are connected at the joint by a resistive pivot connection. The resistive pivot connection has a resistive mechanism which is attached between the struts by matching projections and conduits which are on opposing faces of the struts and ends of the mechanism. The degree of resistance is varied by substituting a mechanism, which is made of an elastomeric material, with another of different resistive properties. Resistance may be varied by changing the positions of the projections and conduits relative to each other. Moving the relative positions of the conduits and projections would also change the muscle group being exercised.

Abstract: A hand holdable, disposable dispension container of low cost construction, generally of plastic, for the dispensing of fluent, generally viscid materials, including processed foodstuff such as ketchup, relish, mustard and jams; creams, handcreams, lotions, colloidal solids such as toothpaste and the like, has a base portion on which the container is free standing, and a valved dispensing outlet located on a lower side face of the container, in underhung protected relation adjacent to the base, to permit downward dispensing of selected quantities of the contents without having to resort to invention of the container. The container incorporates a self-venting pressure balance capability. The container content is always located in the lower part of the container, due to the influence of gravity for immediate dispensing, by squeezing of the container walls, and making possible the dispensing of substantially all of the contents so that virtually none is wasted and thrown out with the container.

Abstract: A splash guard for use on auto vehicles having at each wheel a body panel and a flange which in part defines a wheel well. The splash guard includes a body portion with an upper section and an adjacent mounting part formed to engage and cover the wheel well flange during use. The mounting part being curved in an upright plane of cross section whereby in use it is either undistorted or distorted into a condition of lesser curvature. The body portion also includes a lower section which is dished for enhanced splash protection, and sufficiently curved to disguise splash guard deformation and a lack of parallelism with a road surface. A flange portion projects from the body portion in a rearward direction during use and is preferably of a material capable of deforming to effect a seal between the flange portion and body panel. The flange portion includes a surface which engages the body panel and which is at an acute angle with the surface which engages the wheel well flange.

Abstract: An adjustable safety seat for children for use in a motor vehicle. Height and width configuration of the seat can be easily changed to suit children of different sizes or a growing child.The child's safety seat comprises a pair of side pedestals and a seat bench. Raising of the bench relative to the pedestals for a small child concurrently narrows the width of the seat and lowering of the bench for a larger child concurrently widens the seat.The safety seat and a child contained therein are securely and safely positioned on a vehicle seat by means of the vehicle seat belts.
