Abstract: An eye shield (20) for a bow includes a horizontally-elongated plate-like member (51) operatively mounted on the bow, and preferably to a sight (32) mounted thereon. The member extends toward the head of a person aiming the bow, and, if projected rearwardly, would intersect such person at a point between his eyes. The sight is so dimensioned, configured and arranged as to limit the field of vision of each of such person's eyes, to assist the person in shooting the bow with binocular vision.

Abstract: A fluid coupling (30) has a male half (32) and a female half (31). Each half has a poppet (35,42) arranged to move toward and way from a seat (34,43). The male half (32) has an outer sleeve (38) which is adapted to guide initial joinder of the female half distal end (46). After the two halves have been initially joined, the male half body (39) is extended relative to the sleeve (38) so as to move both poppets (35,42) off their respective seats and to permit flow through the coupling. The coupling has protrusions (76) provided with sharpened edges which are positioned to scrape ice adhering to facing surfaces when the coupling halves are joined and separated.

Abstract: A capsule for absorbing liquid waste which contains a a capsule body, a capsule cap joined to said capsule body, and a powder disposed within said capsule. The body of the capsule consists essentially of water-soluble material. Each of the capsule cap and the capsule body contains a domed-shape end section and a linear body section, each of which contains several orifices. The density of orifices in the domed-shape sections exceeds the density of the orifices in the linear body sections. Disposed within the capsule is a powdered absorbent material.

Abstract: An improved apparatus (11) for emitting infrared radiation of a desired wavelength includes a primary surface (35); a burner (24) for raising the temperature of the primary surface so as to cause the primary surface to emit infrared radiation of a first wavelength; a secondary surface (26) surrounding the primary surface in spaced relation thereto and arranged to be heated by infrared radiation emitted by the first surface and for emitting infrared radiation of a second wavelength toward the object; and an actuator (28) for selectively varying the spacing between the primary and secondary surfaces so that infrared radiation emitted by the secondary surface will be at a desired wavelength and will be focused; whereby the apparatus will emit infrared radiation of a desired wavelength toward the object.

Abstract: This invention most generally relates to a clip mechanism assembleable to the back-side of an ornament member, most preferably jewelry objects or fanciful buttons and the like, to be displayed by removable attachment to clothing mainly through "button-holes" and used, for example, as tuxedo-studs, cuff-links, lapel-pins, etc. The clip mechanism may also be used with hooks or posts upon which may be placed, or hung, tools, pictures, or articles for display. The clip mechanism is removably insertable into a mounting hole or peg-board hole and because of the particular design of the clip mechanism will support the article hung on the hook or post. The clip mechanism is removable with a pulling force in a direction opposite the direction of insertion of the mechanism.

Abstract: A fluid-powered actuator (42) has a body (11) which includes an end wall (16) provided with a through-opening (21). A piston rod (44) has an inner portion (44A) arranged on one side of the end wall within a pressurizable working chamber (24) of the actuator, has a penetrant portion (44B) passing through the end wall opening, and has an outer portion (44C) arranged on the other side of the end wall. The rod is configured such that the transverse cross-sectional area of the penetrant portion is greater than the transverse cross-sectional area of the outer portion so as to define an annular surface (46) which faces away from the actuator chamber. The improvement provides a seal assembly (43) for containing fluid leaking from the actuator chamber.

Abstract: A storm monitoring apparatus and method is described wherein two H-field antennas are oriented with respect to the heading axis of an aircraft or the like at an angle of 45.degree.. The signals developed by these two antennas are picked-up by small R-F transformers which serve the inherent function of integrating the signals and extracting the H-field current component. A printed circuit board structuring of the two antennas provides for consistency of fabrication and reliability as well as compactness. The monitoring apparatus exhibits broad band frequency response to evaluate lightning strike rate to determine storm range and intensity. A computer control test utilizing diagnostic coils at the antenna carries out periodic testing of the performance of the device and a component such as a gravity switch provides an indication to the control system as to the orientation of mounting of the antenna on an aircraft.

Abstract: A method for aligning the process tools of a typical box blank die-cutting machine. The method contemplates the use of alignment openings 21 and 22 on the surface of male and female tools 19 and 20 corresponding to a cut through-hole 16 on test sheet 14. As test sheet is urged through the process, a series of alignment cylinders, 18, 24 are used to insure each of the male and female tools and test sheet are aligned by having the alignment cylinders fall cleaning through the various alignment openings and through-hole. Once the tools at each position of the process are aligned, alignment screws 31 and alignment members 28 on the machine frame 25 serve to fix the position of the tools relative to the position of the sheets to be die-cut, stripped and blanked. Accordingly, the method contemplates alignment and set-up of the machine based upon the urged position of the sheets to be etched and cut.

Abstract: An improved communication system (10) includes a plurality of transceivers (A, B, C, D, etc.) adapted to communicate with one another via a common communication path. Each transceiver has its own unique identity code. The invention provides a cable (11) for temporarily enabling the mutual exchanging of identity codes between only two of the transceivers so as to establish a dedicated pair. Each transceiver has memory (12) for receiving and storing the identity code of the other transceiver of the pair, and for purging any previously-stored identity code. Each transceiver is arranged to identify all communications transmitted by it as having originated from it, and as being addressed to the other transceiver of the pair. Each transceiver is also arranged to accept communications only if addressed to it and if identified as having originated from the other transceiver of the pair.

Abstract: The present invention is a surgical drape 10 specifically designed for surgery on extremities (e.g. arm, hand, leg, foot). The drape 10 comprises a base sheet 11, a work surface 14, a dam 21 having an adjustable opening 22 and cord stays 25-32. The patient 18 lies under the drape while a subject extremity 23 is placed through the adjustable opening. The dam is made of an elastomeric material which forms a tight engagement around the subject extremity. The work area completely surrounds the dam and is substantially stronger than the base sheet to reduce accidental tearing and prevent instruments from slipping off from the drape. The work area extends a substantial distance around the dam to provide adequate protection from accidentally tearing the drape when surgery is conducted near the dam. The cord stays prevent cords from interfering with surgery or becoming contaminated as a result of falling to the operating room floor.

Abstract: An electro-mechanical-hydraulic drive mechanism (10) for moving a lead (11) relative to a support (12) includes an electric motor-driven element (14) and a hydraulic reaction element (15). The two elements are arranged mechanically in series between the lead and the support. The motor-driven element may be operated independently of the reaction element to move the lead relative to the support when the reaction element is held at a fixed displacement. The two elements may be operated cooperatively to move the load when the motor-driven element is operated at a controlled velocity to pressurize the reaction element, and the reaction element is operated by controlling its pressure.
