Abstract: The invention is a traffic signalling post which comprises a flexible rod member, a rigid shaft coaxially secured at one end to the rod member, an anchor bore member adapted to house the shaft for maintaining the latter in a vertical position. The bore member has a perforated elastic diaphragm for peripherally sealing the shaft at a location adjacent the rod member when the latter sits in the bore member. The diaphragm is particularly characterized by a pair of rectilinear lips extending upwardly and adapted to be depressed downwardly with the introduction of the shaft in the anchor bore member and to be raised upwardly by the retraction of the shaft from the anchor bore member.

Abstract: A safety reflector which is attached to a V-shaped bracket that may be used for mounting onto a boat motor or extended load on a trailer. The safety reflector used to notify persons following such a boat or load that the motor or load is present which will possibly prevent accidental hitting of such. The safety reflector is collapsible and may be easily stored when not in use.

Abstract: An indicating mechanism is described. The mechanism is ideally suited for the indication of time but is also applicable to other indicating functions where changing information must be displayed. The mechanism is composed of a flexible belt bearing indicia and three supportive discs. As the discs are caused to rotate, the belt and any indicia on it will rotate. This rotation will be apparent to users who see or touch the indicia on the belt, thus providing an indicating function. The unique geometry of the belt gives two full circular discoidal surfaces for decoration. Typically only one of these surfaces will be visible to users as the other is disposed directly below it. This arrangement allows times within each 12 hour period in the 24 hour day cycle to be indicated uniquely while maintaining the conventional location of each AM and PM hour's representation of the clock face.

Abstract: A high pressure, fluid level sensor and seal includes a body supporting a removable end cap and housing a trunnion bearing comprising a pivot disk that is pivotable about a pivot axis formed by a pair of pivot pins that are secured to the base of the end cap. The pivot disk is connected to a control arm that freely passes through the end cap. The pivot disk is also connected to a displacer arm that engages a float or displacer in communication with fluid in a high pressure tank. A compression spring acting between the control arm and the end cap biases the pivot disk against the pivot pins. The control arm engages an operating mechanism in a controller that includes a relay. The body is secured in the wall of a high pressure tank. A high pressure seal is formed by a spacer that forms a slip fit with an annular recess on the pivot disk and which engages the end cap and O-rings. The O-rings couple the spacer to the pivot disk and couple the spacer to the end cap.

A movable stop bar 75 is provided on the reloading chute 71 to prevent unintentional discharge a replenishing supply of drop markers through the discharge end 73 of the reloading magazine 70.

Abstract: A traffic warning mat apparatus is provided for use in combination with a vehicle of a type having a trunk lid pivotally attached to the vehicle. A mat is adapted to be disposed on the rear of an automobile. A light reflecting material is disposed on one side of the mat for making the mat highly visible to vehicles with headlights which shine onto the mat or, under daylight conditions, can be easily seen. Straps are connected between the top of the mat and a gutter hook which extends around the front end of the trunk lid. Straps are attached to the bottom of the mat and have gutter hooks thereon for attachment to the underside of a vehicle or to the bottom of a bumper thereof. Additionally, straps are connected to the side edges of the mat and these straps have gutter hooks on one end thereof for attachment to the bottom rear ledge of the trunk lid. Each of the aforementioned straps include mechanisms for tightening the straps for securing the mat on the rear of the automobile when in use.

Abstract: A liquid level sensor comprises an elongated tubular member with two open ends contained in an elongated cylindrical container vessel in an arrangement wherein the two extremities of the elongated tubular member extending through the wall of the elongated cylindrical container vessel are respectively open to a liquid medium that rises through the elongated tubular member to the same level as the free surface thereof and to an ambient air above the free surface of the liquid medium; wherein the level of the liquid medium is determined from a natural frequency of flexural vibration of a section of the elongated tubular member partially filled with the liquid medium; which combination may further include another section of the elongated tubular member completely filled with the liquid medium, wherein the density of the liquid medium is determined from a natural frequency of flexural vibration of the section completely filled with the liquid medium and the level of the liquid medium is determined from a combinati

Abstract: A combination book marker and pen holder designed so that when the book marker is placed between two pages of a book the pen is oriented in an exposed position extending along the upper edge of the book. The pen is readily accessible for use when needed for marking passages in the book or making notes on the content of the book. The pen holder is adjustable in size to accommodate different diameter pens. A thin flat panel has one end zone extendable beyond the upper edges of the book pages when positioned within the book. The pen holder is mounted on the end zone. The holder is formed from a single strip of material having a flat central strip section and two resilient circular coil sections extending in opposite directions from the flat central strip section so as to be resiliently biased into contact with each other. The coil sections spread apart to releasably retain a pen inserted between the two coils.

Abstract: A gear range indicator for use with automatic transmission which is remote from the shift mechanism, yet requires little or no adjustment to be made to the mechanical linkage to compensate for variations in the position of the display relative to the shift mechanism. The gear range indicator uses light conducting columns to illuminate symbols corresponding to the gear range selected. An opague indicator control strip with an aperture blocks light from reaching the columns except for that light passing through the aperture. The aperture is aligned with the column corresponding to the gear range selected.
