Abstract: An apparatus which transmits a laser beam to a target, such as an area of human tissue being treated. Delivery of the beam and its direction to the target area is controlled safely. The apparatus is operatively connected directly to an instrument, such as an endoscope or laryngoscope, which identifies and defines the target area. A joy-stick assembly provides control of the direction of the beam as it enters atmosphere from the apparatus, by manipulation of its lever which swivels its mirror from which the beam is reflected towards the target area. Means to block transmission of the beam from the apparatus to atmosphere is coupled with a fail-safe arrangement of elements whereby only when the mirror is in a proper swivelling position to reflect the beam to the target area is the beam emitted from the apparatus. An adjustable sliding lens system within the apparatus provides change of focus of the beam to effect a change in the plane of treating the target area.

Abstract: A drafting template having printed thereon a pattern of non-concentric elliptical portions, preferably forming complete ellipses, a vertical measuring line extending upwardly from a common point for the pattern or from a base point for the vertical measuring line, and a horizon line mounted at a scaled height above the base point and being parallel to the major axes of the elliptical portions or ellipses. The pattern is a perspective view of concentric circles or portions thereof taken at a scaled distant station point and scaled height above the plane for the circles. The horizon line is mounted at a scaled height above the base point. By selecting one or more vanishing points on the horizon (line), and drawing lines on an overlaying drafting sheet correlated to the base point between the vanishing point(s) and base point, such drawing lines intersecting the elliptical portions or ellipses, a lined grid field can be ultimately produced on the drafting sheet.

Abstract: A device (10) for directionally controlling a beam of light, particularly adaptable with a laser beam in surgical operations. The beam is focused in a chamber (10) by a lense (46) (one of a selectable number), passes through a passageway (16) through which the operator or surgeon observes the target area for the beam, and strikes a specular element or mirror (27) in a cavity (26) separated from the chamber (12) by the passageway (16). The disposition of the mirror (27) in the cavity eliminates vignette obstructions of such element that heretofore was disposed in the passageway in prior teachings. The beam reflects from the mirror (27) in the direction of the target. A unique joystick (28) is operatively connected to the mirror (27) to swivel same and thereby control the direction of the beam. The device (10) is mounted to an adaptor (20) for 360.degree. rotation thereabout.

Abstract: A portable coolable beverage or liquid dispenser made of insulating material forming a base unit, shell and cap, all joined to form a chamber in which a pliant or ductile beverage-containing vessel is mounted on and partially supported by a container having a reservoir which captures the vessel's beverage after the latter's release therefrom. Such release occurs in the assembly for use of the dispenser, as a portion of the vessel's skin within a threaded collar connected to such skin is punctured by a tip on a sleeve extending through a threaded opening in the container's lid. The lid's opening and the vessel's collar are secured together prior to closure of the container by its lid. The container's reservoir is sealed by such lid closure to avoid contamination of the beverage. Spacial dimensions about the vessel and container provide for introduction of ice into the chamber, and a passageway from the reservoir to an external spigot provides the manner of dispensing the liquid.

Abstract: A positive action basin wrench comprising a torsion bar spring mounted in a hollow shaft of the wrench and which is actuated to produce a pre-load grip on a work element (nut) held between a pair of jaws, one being movable. A tubular member in the shaft drives the torsion bar spring the action on which causes a pinion/gear arrangement at the head end of the shaft to turn a post rotatably mounted in a transverse extension to the shaft, the movable jaw in turn rotated as the post is rotated and being mounted atop the extension. The driving member for the spring rotates in the shaft to the extent of a pair of opposing aligned slots therein, by means of a crossbar projecting through such member and out of the slots in the shaft. As the crossbar is rotated, the tubular member and spring turn before the shaft does, causing the movable jaw to grip with the fixed jaw the nut, while reaction in the spring twists it until the crossbar is stopped by the slots' ends.

Abstract: The invention comprises a two-member bracket assembly each member cooperating with the other. A locking effect is produced on an article, such as a screw or bolt, securely mounted in a wall or the like. The first member includes a bight that is securely mounted to a frame or the like that is to hang on the wall. The bight via an aperture in it is thrust over, say, the screw-head of, the article in the wall. The second member cooperates by engaging the bight in the latter's cavity, sliding therealong and into a position on such article to lock the bracket assembly to such article. This locking effect is obtained by the second member including sections which define a slot that clips on to the article, say, behind the shoulder of the screw-head in the example above, that has been thrust through the aperture of the bight.

Abstract: A solid-state dimmer control circuit using opto-isolators, whereby the effective power to be supplied to a load is selectively varied. The opto-isolators couple a variable pulse switching circuit to a full-wave switching circuit which includes back-to-back silicon-controlled rectifiers. The variable pulse switching circuit is connected to means for generating a selectively variable control signal that is proportional to the power to be supplied to the load. A single a.c. power source is provided both switching circuits.

Abstract: A concealable signaling, e.g., radio alarm, device worn on the person and actuated by concealed switch means that include mechanical detents. The engagement of the detents provides secret tactile information back to the wearer. The presently preferred embodiment is a miniature radio alarm transmitter concealed in a device which also serves as a belt buckle. The wearer distends his waist to actuate the transmitter. Tension in the belt moves an element through one or more detent engagements before it activates the transmitter. These detent engagements make transient changes in the belt tension which are felt by the wearer; these inform the wearer of impending activation, so preventing false transmitter signals or alarms.

Abstract: An alarm device which eliminates the possibility of totally disarming its alarm by a thief. In one embodiment, a magnet is swiped by a reed switch a predetermined number of times to set the device in an armed condition. With each swipe, a stepper arm in the electrical circuitry moves from one contact to the next, until in a contact position, known only to the authorized user, that sets the device in such armed condition. Should any current be drained off from the electrical source (battery) to energize any car electrical circuit (light bulb, say), current is also then made available to the armed device through the stepper arm contact, the alarm of the device thereby being activated. A simpler embodiment includes a mechanical latching relay DPST switch which is normally open, but is closed upon a magnet passed over a first reed switch to arm the device. The magnet is passed over a second reed switch to open such relay switch, disarming the device.

Abstract: A pictorial display system in which continuously updated images of `other ship` aircraft within a specified airspace envelope are superimposed on a map display along with the pilot's `own ship` position, whereby collision threats are avoided by taking corrective flight action. This information is displayed, independently of and without interfering with ground facilities operations and communications, as a response to a low-powered signal transmitted from an onboard FM transceiver-multiplexer unit in which the response in terms of positions and altitudes of other aircraft in electrical form, is received, demodulated and then transformed into digital form. Such digital information along with "own ship" position and altitude in digital form, are fed into an altitude discriminator synchronizer unit.

Abstract: An article of manufacture to eliminate ease of destruction of a slotted hasp and/or staple combination utilized to lock a door, secured together by a padlock, whereby unauthorized entry is prevented. The inventive subject matter includes a pair of spaced rigid members in secured relationship to each other, with each having an aperture placeable in contiguity and alignment with the pocket or cavity of the staple which displaces the void or spacing between the secured members. One species of the invention includes a horizontally-disposed segment at its rear end and which maintains in spaced position the members to each other, the members terminating at their other ends or faces in an open manner in order for a slip-on connection to the staple after the hasp's slot is in placed or closed upon the staple. With such connection, the rear end abuts the staple's bow while the configuration of the guard's faces at its open end cooperates with the form of the hasp.
