Abstract: An alarm device for use with doors, windows, and the like for causing a loud gunshot-like signal upon unauthorized entry is disclosed. The alarm device includes a compact housing having a chamber therein containing a firing mechanism and a detonatable gas generator cartridge. The cartridge communicates with an opening in the housing whereby when the cartridge is detonated, the gases rush through the opening resulting in a loud gunshot-like report. The chamber of the housing is closed by a movable cover which is constructed to hold the firing mechanism against acting on the cartridge. The housing is shaped for mounting on a door or window surface with the cover engaging the frame of the door or another part of the window, such that when the door or window are opened the cover will move to release the firing mechanism to strike and detonate the cartridge. The alarm device is also provided with a lock to secure the cover from moving until it is desired to activate the device.

The mechanism (10) includes a pair of opposing locking elements (18), selectively spreadable to frictionally engage a slot (20) formed in the adjacent member (16); and also including an adjustment knob (44) axially fixed relative to the locking elements in mounting plate (12) attached to a movable member or fixed member, rotation of the adjustment knob (44) allowing precision adjustment of the position of the movable member after the locking element (18) is engaged with the slot (20).

Abstract: A centering gauge tool for determining if an axial bore is disposed concentrically relative to a desired center. The tool preferably has four sensing fingers equally spaced about a conical core, the finger being resiliently biased away from the surface of the core and depressible against the resilient urging into engagement with an electrical contact member connected in a circuit with lights and a source of electrical energy. When the tool is inserted within the bore of a workpiece and the bore is concentric about the axis of the workpiece relative to axes the tool, all of the indicator fingers will be depressed substantially simultaneously to light all the indicators. If the bore is eccentric, when the tool is inserted within the bore less than all the fingers will engage the wall of the bore and effect a lighting of less than all the indicators.

Abstract: An electronic measuring rule wherein the rule tape is formed integrally with a magnetic recording tape imbedded therein along the longitudinal axis of the tape rule. The recording tape which has spaced indicia signals recorded thereon is molded into a recess along the longitudinal center of a vinyl tape so that the vinyl tape covers the outer edges of the magnetic recording tape and the back thereof. A thin protective resin layer covers the recorded side to protect it from abrasions during use. Visible indicia are printed on both sides of the vinyl tape, top and bottom, on each lateral side so that the tape may be "read" visually in the usual manner from either lateral side, both top and bottom.The recording tape portion of the measuring rule is "read" directly by a pick-up head located within the case adjacent the location where the tape exits the enclosing case.

Abstract: A golfing scores recorder consists of a generally rectangular case having a plurality of openings formed in a predetermined pattern provided in its front panel and a plurality of depressions of the same pattern formed in the inner surface of its rear panel. A perforable score card is insertable into the case. The score card has a score recording pattern printed thereon which has a plurality of score recording areas in register with the pattern of openings in the front panel of the case. The dimension of the openings in the front panel is sized to permit a golf tee to be inserted therethrough to pierce a mark in the score card to provide a permanent recording of the number of strokes played in each hole of the golf game.

Abstract: A radiant-energy temperature measuring apparatus of a scanning type having a linear array of light-sensitive elements which generate photoelectric signals corresponding to respective amounts of radiant energy produced at different points of an object and vicinities thereof on a straight line corresponding to the above linear array, and further having a device for determining a temperature of the object at desired one of its different points, based on the photoelectric signal generated by one of the light-sensitive elements which optically matches the desired one point of the object. The apparatus includes an edge detector for detecting an edge of the object, based on the photoelectric signals generated by the light-sensitive elements, and a selector for selecting the desired one point of the object, by designating a number of the light-sensitive elements as counted from the element corresponding to the detected edge of the object, to the element which corresponds to the above-indicated desired one point.

Abstract: An under layer of a mortar material such as stucco is first applied to a structural surface such as a wall or floor. Over this under layer a second layer is applied generally of a different color than the first layer. A tool having a guide bar, an elongated strip forming a measuring rod removably attached along one edge of the guide bar, a bubble level mounted thereon and a handle for manipulating the guide bar is used to form a straight edge for a mortar scratcher which is used to groove channels in the top layer of material. The measuring rod is placed in successive channels thus formed to provide a guide for the formation of subsequent such channels. The measuring rod is removably attached to the guide bar and can be selectively positioned in a vertical orientation relative thereto or in predetermined angular orientations so that the guide bar can be utilized in forming channels at right angles or acute angles relative to the channels initially formed.
