Abstract: A device for coupling a rotary member to an axially movable input stem of a linear displacement transducer comprises an axially movable element which is coupled to the stem and threadedly engages the rotary member. The axially movable element is restrained against rotation by spring loaded detents and has abutments which can engage a lug on the member when the element reaches its limiting axial positions. This engagement causes the element to be rotated with the member and input to the transducer is arrested.

Abstract: An electrocautery instrument which is provided with a non-removable enclosed electrical switching mechanism. The entire switch assembly may be sealed from human contact by an insulating medium.

Abstract: A structure and method of improving the exterior appearance of a building is provided wherein a frame and panels simulating windows are installed on the exterior of the building. The frame is installable on new or existing construction.

Abstract: A dispenser for maintaining light sensitive substances utilized in the practice of dentistry shielded from light and providing easy and convenient access by the dentist includes a container and a cover therefor with the cover being hingably attached to the container. The container includes a plurality of recesses for receiving one or more light sensitive substances. The container is provided with structure such as a finger hold on the bottom or an elastic band for maintaining the container on one or more digits of a hand and the cover is provided with a ring or other suitable structure for maintaining the cover in operable engagement with another digit of the hand, such as a thumb, whereby the dispenser may be held in one hand and readily opened and closed to provide easy, quick, convenient access to the light sensitive substances by the dentist.

Abstract: Joystick controller apparatus in which a pair of joystick controllers may send signal bursts on the same communication channel in the infrared frequency range by means of an electromagnetic transmission without recognizable loss of data. An error checking system is also provided to eliminate the effects of noise. A universal cable connector is provided for connection to various video game apparatus.

Abstract: A flow through polarographic or other voltammetric analyzer utilizes an improved deoxygenator/pulse dampener in the form of a knitted or other form of convoluted oxygen permeable tubing, such as silicone rubber tubing, through which the flow sample passes. The oxygen permeable tubing is mounted in a chamber containing a flowing inert gas under a positive pressure.

Abstract: A device for mounting a writing pad structure having dual faces on opposite sides, comprises a frame structure having parallel members which may be inserted in a folder or compendium. A transverse member is connected between the parallel members and slides along the length thereof. The writing pad structure is hingeably mounted on the transverse member such that the writing pad structure can be turned over to expose either face thereof, the transverse member sliding along the parallel frame member, to permit writing to take place on the exposed face. The writing pad structure remains substantially within the zone defined by the parallel frame members.

Abstract: A rotary to linear converter has a rotary input shaft and a linearly movable output element. A torque limiter arrests rotation of the shaft at a critical value of torque thereon. A friction device increase the torque on the shaft if a predetermined axial force on the output element is exceeded, this torque increase being sufficient to operate the limiter. The arrangement renders operation of the torque limiter directly responsive to axial force on the output element.

Abstract: Hypoallergenic jewelry and a method of making the same is achieved by providing vapor deposition of unsubstituted and substituted linear homopolymers and copolymers of poly(p-xylylene) on the jewelry having a thickness in the range of about 0.5 microns to about 25 microns. A new use of preventing allergic reactions when jewelry is worn is achieved by providing the jewelry with a poly(p-xylylene) polymer coating which provides a hypoallergenic surface on the jewelry.

Abstract: A first control element is movable to control fluid flow between ports in a housing. A second control element is movable by an electric force motor and engages the first element through biasing springs so that in normal use the elements move in unison. An arrangement of ports and passages in the elements has the effect that relative movement between the elements as a result of jamming of the first element causes fluid pressure to be applied to the first element to overcome the jamming.

Abstract: A vibration or impact isolator for use between bodies and/or structures, such as between a boat and a dock, is formed from a resilient elongated strip of resiliently flexible material of uniform lateral cross-section wherein longitudinal lateral portions of the strip are formed in the shape of open involutes extending through at least 270 degrees in the unbiased or undeformed condition. An intermediate portion or central portion of the strip between the two lateral edges, which connects the involutes, is deformable on mounting of the longitudinal strip to one of the bodies.

Abstract: A temperature compensated fluid metering valve has a body including a ported sleeve in which a metering element is slidable, the thermal coefficient of expansion of the sleeve and metering element being identical and different from that of the body. The sleeve is secured at one of its ends to the body and a device for detecting the position of the metering element is secured to the body at the other end of the sleeve. The dimensions of the body and the coefficients of expansion are selected so a change in temperature results in an apparent position error signal from the device, this signal repositioning the metering element to compensate for changes in specific gravity of the metered fluid as a result of the temperature change.

Abstract: A solarium structure provides a muntinless exterior appearance by eliminating the outer retaining member of the horizontal muntins. The glazing panels are supported between an inner supporting member and an outer retaining member of the mullions and by the top and leg of an inner supporting horizontal muntin. The space between the glazing panels which overlies the legs of the T's of the substantially horizontal muntins is covered by a caulking material, which is preferably a silicone material.

The chimney (18) through which the burnt gases produced during heating of the melting chamber (1) pass is arranged in the cover (14) of the holding chamber (2), namely at the end of the holding chamber (2) opposite to the openings (6).

Abstract: A deep-bore drilling machine consists of a deep-bore drilling unit (1) which is driven by rotation and has a deep drill tool (4, 7). The front end (7) of the deep-bore drilling tool (4) is led into the drill bushing (10) at the beginning of the drilling operation. The drill bushing (10) is thereby contained in a main spindle (22) and is replaceable. Also, the main spindle (22) can also be driven independent of drive (2) of the deep-bore drilling unit (1) by another drive (30).
