Abstract: A simple camera for use in a telescope having a hollow support cylinder that is capable of being slipped into the focus mount tube of the instrument for mounting and positioning the camera in reference to the image plane of the telescope. The cylinder depends from the base of the camera and encloses an aperture formed in the base so that the telescope image is allowed to pass directly into the camera. The main housing of the camera is pivotably supported on the base and contains a plurality of film-holding compartments that can be selectively moved over the aperture to expose the film contained therein whereby a number of exposures can be made without having to reload the camera. A viewing window is further provided in the housing that is also capable of being positioned over the aperture to permit visual observation of the image without having to remove the camera from the instrument.

Abstract: An RF control system suitable for use in a mass spectrometer of the type having an ionization chamber, a mass filter and an ion detector. A constant frequency RF voltage is applied to the filter. The magnitude of the RF signal is varied in response to a DC control signal to permit selected ions having a desired charge-to-mass ratio to pass through the filter and strike the detector. In the control system the generated RF signal is attenuated and added to the DC control signal. The resultant voltage is applied to a comparator-integrator circuit that is arranged to provide a control signal capable of precisely holding the output of the RF generator at a predetermined peak voltage.

Abstract: A simple and inexpensive camera for use in conjunction with a telescope that includes a hollow mounting cylinder that is able to be conveniently slipped into the focus mount of the telescope to align the camera along the optical axis of the instrument and to properly locate the camera thereupon. In assembly, the cylinder depends downwardly from the bottom of the camera housing and conducts the telescopic image into an exposure aperture passing vertically through the housing. A film slit passes horizontally through both the housing and the aperture to provide a guideway for positioning film over the aperture within the image plane of the telescope. A slide containing a ground optical element is slidably supported in the aperture whereby the element is movable into a first position within the image plane of the telescope to present a light image of an observed body thereupon, and into a second position wherein the bottom surface of the element is coextensively aligned with the top wall of the film slit.

Abstract: A cross country ski binding that includes a toe piece affixed to the boot of a skier which is slidably received within an open sided base section secured to the ski. A rocker bar is rotatably mounted in the base that contains a pair of downwardly extended, contoured lugs that are adapted to be received in openings formed in the top surface of the toe piece. An adjustable biasing means acts upon the rocker bar to pressure the lugs against the front face of the receiving openings. The front wall surface of the toe piece is arrested against the base section and is arranged to pivot laterally in either direction about its two side edges so that the toe piece can be freed from the ski piece in the event the skier overcomes the holding pressure exerted by the lugs upon the toe piece.

Abstract: A kerfless slitter, capable of cutting various materials without generating chips or sawdust. The slitter includes a circular blade having a plurality of teeth spaced about its outer periphery and which contains a knife-edge centered along the mid plane of the blade in regard to its thickness. In practice, the blade is rotated at a peripheral speed that is equal to the linear speed of the work acted upon whereby each tooth is advanced along a cycloidal path of travel in reference to the work. Each tooth is arranged to enter the work ahead of the cutting line established by the teeth that have previously penetrated the work so that the cut is increased in length and in depth by means of a series of short slits.

Abstract: Apparatus for automatically locking the blade mechanism of a vehicular driven snowplow at a desired angular position in regard to the forward line of movement of the vehicle. The locking device is adapted to automatically release the blade mechanism when the blade is raised from a normal snow clearing or working position and to move back automatically into locking engagement when the blade mechanism is lowered into the same or a new angularly disposed working position.

Abstract: Apparatus for lifting, repositioning and transporting relatively large storage drums that includes a carriage containing a movable frame in which is pivotably supported an open ended drum saddle. The saddle is made up of two parallel side rails joined together by a back rail. The distance between the side rails is less than the diameter of the drum whereby the drum can be cradled in a horizontal rest position within the saddle with one of its planar end walls seated against the back rail of the saddle and its cylindrical side wall resting between the two side rails. A cinching mechanism acts in cooperation with the saddle to securely lock the drum to the rails. In operation, adjustment of the frame and the saddle is accomplished independently to permit a drum to be lifted from either a horizontal or vertical rest position and brought to any desired secondary position within the operating range of the apparatus.

Abstract: A method of constructing a burner for efficiently burning a wide variety of fuels without having to add auxiliary fuel to the system or provide special air handling equipment. In the main embodiment of the invention, two cylindrical burning sections are superimposed one over the other in a cross-like configuration. The lower cylinder serves as a primary burning chamber in the system while the upper cylinder serves as an afterburner. A conveyor transports raw fuel from the front of the primary chamber through an extended burning zone. The rear of the chamber remains open to the atmosphere so that air is drawn over the moving fuel bed in the burning zone in counterflow relationship therewith. An elongated duct is aligned within the primary chamber over the burning bed of fuel and is arranged to accelerate volatile gases generated in the primary chamber into the afterburner. The angular relationship between the two cylinders is adjusted so that the turbulent vortical flow is created in the afterburner.

Abstract: Method for treating a fluid containing anaerobically digestible nutrients and organic substrates wherein a plurality of individual anaerobic microorganisms are established upon rotatable discs mounted within an enclosed housing and a stream of treatable fluid is passed through the housing to wet more than fifty percent of the disc surfaces. The discs are rotated through the fluid whereby the microorganisms are able to feed upon the nutrients and substrates in the fluid and expel a process gas into the atmosphere maintained over the fluid. To further enhance both the feeding of the microorganisms and the expulsion of gas, the housing is divided into a number of individual compartments or stages and the pressure is reduced below atmospheric pressure in each compartment.

Abstract: A retention system for safeguarding a surgical incision to prevent rupturing of the wound during healing wherein at least one pair of elongated retaining bars of similar design and constructuion are positioned on either side of the incision. The bars are cojoined by means of retension sutures embedded beneath the skin which pass transversely across the wound. Each bar consists of a relatively rigid top plate and a complimentary lower pad that is secured to the bottom surface of the plate and which is adapted to conform to the contour of the body. One or more pair of suture holes are spaced along the longitudinal axis of each bar with the spacing between the holes being substantially equal to the width of the bar at the contact surface whereby a relatively uniform holding pressure is evenly distributed over the entire contact region when the retention sutures are tied off.

Abstract: A detecting element for sensing the presence of higher than normal concentrations of ozone in air at ambient temperatures and pressures. The element is formed of a "lower" oxide of a semiconductor having a variable valence. In the presence of ozone, two free electrons in the conductive band of the semiconductor combine with dissociated atomic oxygen to form a "higher" oxide of the semiconductor thereby changing the conductivity of the element. At least two electrodes are placed in spaced apart contact with the element to permit a current to be passed therethrough whereby the change in conductivity can be discerned.

Abstract: A method of manufacturing a solid state sensor wherein a reactive compound of an alkali metal is tightly packed between a central electrode and a surrounding ion shield. A heating coil is wound about the outside of the shield. The ion shield is formed of a material that is deplete in ions of alkali metal and serves as a ion depletion boundry in the system.

Abstract: A preformed structural member that includes an elongated web having first and second flanges projecting laterally from its two longitudinal edges. Each of the flanges is of different construction, however, the flanges of two or more members can be interlocked to form either a right angle corner sections or continuous flooring or ceiling sections. Similarly, the member can be easily snapped into operative relationship with flat panels to create a self-standing sub-assembly possessing sufficient holding power to temporarily support the cojoined components until such time as they can be more securely locked together in final assembly.

A pair of guide elements are provided which engage the leads to seat them upon the sprocket drive and to positively hold the leads thereon as the components are advanced through the work stations.

Abstract: A structural member having similar flanges mounted on either end. The flanges of individual members can be interlocked to form either right angle sections or rectangular columns.

Abstract: A structural frame in which vertically aligned metallic studs are secured to horizontal metallic runners or the like by means of clips to create a strong, easy to erect, partition. Each clip includes two upraised legs that are connected at their upper ends by means of a sinusoidal shaped section. The lower end of each leg contains an outwardly extended locking key. In assembly, the sinusoidal section of the clip is received within a slotted hole formed in the stud with the bottom of the slotted hole being seated against one of the peaks of the sinusoidal waveform section. The clip is crimped to allow the keys to pass through a pair of receiving holes formed in the horizontal runner. The crimping force on the clip is released whereupon the locking bars are driven beneath the holes to lock the clip in place and thus secure the two structural members in assembly.

Abstract: A clutch brake unit suitable for use in conjunction with a heavy duty clutch assembly for retarding the motion of the driven clutch shaft. The unit is actuated by the clutch release mechanism which causes the unit to be compressed between a movable member and a stationary member as the clutch is being released. A pair of discs, adapted to positively engage the shaft in sliding relationship therewith, are initially engaged by the members in friction driving contact and forced together against the biasing pressure of a wave washer mounted therebetween. The discs are independently mounted for compression within a relatively rigid housing. When the discs are compressed to a predetermined depth, the two members engage the housing thereby preventing further loading of the shaft.
