  • Patent number: 5303169
    Abstract: A computer senses a voltage which is representative of wall thickness and defines with the use of a voltage/thickness curve the thickness of that wall portion. To define this curve, a plurality of voltage/thickness points are inputted by a sensor into the computer Each point is defined by sensing and defining the voltage of a wall portion on a calibration standard having a known thickness and defining a calibration thickness corresponding to that voltage using the following equation{((Calibration Standard Diameter in inches -Container Diameter in inches).times.0.2)+1}.times.Calibration Standard Thickness in mils, andequating these calibration thicknesses to the corresponding voltages produced by the sensor when sensing at least two thicknesses of the standard.

  • Patent number: 5154376
    Abstract: A cable-securing device having a locking head and a flexible strap extending therefrom in the form of a ladder having cross bars extending between parallel side members. The cross bars are larger than the separation of the side members so that they are bent as they lie in the plane of the side members. The device has a projecting locking peg which forms a cable-securing loop when a cross bar is engaged by the locking peg.

  • Patent number: 5121068
    Abstract: A capacitive sensor senses the wall thickness of an object. The sensor has an electrode covered by an adhesive tape including a non-transparent glass cloth tape layer which engages the object and a layer of silicon or acrylic adhesive for securing the tape layer to the electrode. The adhesive and tape have a dielectric constant that is constant throughout the temperature range in which the sensor is to operate.

  • Patent number: 5066838
    Abstract: An automobile brake switch assembly including a mounting clip and two brake switches, each brake switch including a threaded, cylindrical plunger housing. The mounting clip includes two hollow, cylindrical sleeves, each having an inner diameter slightly larger than the outer diameter of the threads on one of the brake switches. The sleeves are integrally molded, together with a plate that joins them, out of acetal plastic. Each sleeve includes a thread-like tooth molded about the inner circumference and located approximately centrally in the cylinder. Four slots are formed in each sleeve parallel to and spaced about the cylindrical axis, the slots cutting the tooth to form four teeth. The slots permit expansion of the teeth when the threaded plunger housing of the corresponding brake switch is pressed into the sleeve so that the threads may ratchet on the teeth.

  • Patent number: 5061309
    Abstract: A pusher system for transferring formed glass bottles from a plurality of deadplates which are part of an I.S. machine to a common conveyor. A discrete pusher is associated with each dead plate and can transfer the bottles on that dead plate to either of two spaced lines along the conveyor thereby enabling a multiplicity of bottle rows to increase conveyor capacity.

  • Patent number: 5028769
    Abstract: Apparatus for reading code elements which are relieved from a container. A source of light projects normally at the code elements while the container is rotated to sequentially illuminate each of the code elements. A sensor receives light which is reflected approximately normal to the surface of the container but avoids light which is reflected from the surface of each code element at an appreciable angle relative to the normal. The intensity of the reflections from regions of said container not containing a code element are relatively large compared to reflections received from portions of the container surface containing a code element and a threshold is set therebetween.

  • Patent number: 5025117
    Abstract: A u-shaped timer housing body has a pair of elongated legs, a closed end, an open end, and a pair of open sides. There are a plurality of electrical switches, each switch including a pair of contacts, one of which comprises a terminal-switch blade combination passing through and secured to the closed end of the housing body. A cylindrical cam assembly, including a cam shaft, is rotatably supported by a pair of side panels, one end of the shaft mounted in a bearing in each of the panels. The panels and the housing body have a tongue and groove construction which permits the panels to be slid into the housing body along the legs, the panels closing the open sides and the cam assembly entering the housing through the open end, in a direction along a radius of the cam axis. A cover plate snaps onto the housing body, closing the open end and locking the panels and the cam assembly in place.

  • Patent number: 5020343
    Abstract: A lockset for a door comprising a latchbolt assembly movable between a partially extended latching position, a fully extended deadbolt position and a retracted position. A spindle extends through the latchbolt assembly in a direction transverse of the direction of movement of the bolt. The spindle is connected to the bolt for moving the bolt between its positions upon rotation of the spindle. An operating assembly includes a hand operator having a locking member therein, a first plate mounted for linear movement in a direction transverse to the axis of the spindle and having a pair of ears vertically spaced about and generally aligned with the longitudinal axis of the spindle. A pivotally mounted actuator member is movable in response to the hand operator and has first and second surfaces vertically spaced about and generally aligned with the longitudinal axis of the spindle and in engagement with the pair of ears such that pivotal movement of the actuator produces linear movement of the first plate.
