Abstract: An improved mirror mount assembly is disclosed. The mirror mount assembly provides a post assembly slidable in a Y-axis orientation and a nut plate assembly slidable in an X-axis orientation and a device for simultaneously locking the post assembly and the key assembly in a fixed position.

Abstract: Superconducting mirror surfaces are provided by forming a mirror surface from a material which is superconductive at a temperature above about 40.degree. K. and adjusting the temperature of the surface to that temperature at which the material is superconducting. The mirror surfaces are essentially perfect reflectors for electromagnetic radiation with photon energy less than the superconducting band gap.

Abstract: A digitally programmable waveform generator for generating completely arbitrary digital or analog waveforms from very low frequencies to frequencies in the gigasample per second range. A memory array with multiple parallel outputs is addressed; then the parallel output data is latched into buffer storage from which it is serially multiplexed out at a data rate many times faster than the access time of the memory array itself. While data is being multiplexed out serially, the memory array is accessed with the next required address and presents its data to the buffer storage before the serial multiplexing of the last group of data is completed, allowing this new data to then be latched into the buffer storage for smooth continuous serial data output. In a preferred implementation, a plurality of these serial data outputs are paralleled to form the input to a digital to analog converter, providing a programmable analog output.

Abstract: A self-starting windmill of the vertical axis type. Upstanding helical in configuration, pivotally mounted outer blade members surround a central, rotatably mounted shaft are connected to the shaft by radially disposed strut members. Arcuate in planform, pivotally mounted inner blade members are mounted radially inwardly of the outer blade members in a collective triangular configuration and have their respective convex surfaces facing toward the shaft. A weight member and a spring member bias a preselected edge of each outer blade member against wind force.

Abstract: A reverse osmosis (R.O.) water purifier system that collects and stores pure water at low pressure and dispenses it at high pressure. Impurities left behind when the water passes through a R.O. module are disposed of by two methods: the fast flush method and the slow flush method. In the fast flush method, water entering a R.O. module may take two paths to escape therefrom. The first path constrains it to travel through a semi-permeable membrane in the module which filters out undissolved solids and which restrains the passage of dissolved liquids. The second path allows it to travel through the R.O. module, without passing through the membrane, thereby carrying out those impurities left behind by the water passing through the membrane. The purified water is directed to one side of a compartmented storage tank and the waste water from the module is directed to a control valve.

Abstract: A pillow having storage compartments. The compartments may be used to store suntan lotion, beach, poolside or camping accessories. The stored articles are protected from theft because the compartments are hidden from view when the pillow is in use; specifically, they are positioned on the underside of the pillow so that when the pillow is operatively deployed, the existence of the storage compartments may not be ascertained by visual inspection.

Abstract: An engine protection apparatus that monitors several engine functions and that disables the engine in response to the detection of undesireable operating conditions. When ambient temperatures are low, an extended engine warm up period is provided; since the vehicle may be left unattended during an extended warm up period in a cold climate, the engine is monitored during the warm up period so that it may be disabled by the apparatus if an undesireable operating condition arises. Similarly, when ambient temperatures are high, an extended engine cool down period is provided; since the engine may be left unattended during the cool down period, the engine is monitored by the apparatus and disabled if an undesireable operating condition is detected. The apparatus also monitors the engine during its normal operating times, in addition to the warm up and cool down periods of time.

Abstract: A device for handling liquid fluids drained from vehicles. The device includes a fluid storage tank, a container for holding fluid to be recycled, a funnel having an anti-splash mat positioned therein to prevent the splashing of fluid being drained, and a valve means operative to direct the fluid to either the storage tank or to the recycle container for subsequent reintroduction into the vehicle. The valve means also includes means for connecting an air compressor to the storage tank so that compressed air may enter the tank and expel the fluid therefrom through a hose. The storage tank is mounted on casters for mobility and the size of the funnel's opening is sufficiently large to capture fluid flowing from widely spaced sources.

Abstract: An apparatus that cleans printed wiring assemblies. A plurality of assemblies are positioned in a rack on their respective edges so that each of them is maintained in a substantially vertical plane. A spray header member mounted for reciprocation between an uppermost and a lowermost position has a plurality of horizontally disposed support members that are positioned in staggered relation to the assemblies to be cleaned so that when the header member travels downwardly, the support members enter into the spaces between the rows of assemblies. A plurality of nozzles are formed on the support members, and direct a fan-shaped spray onto the assemblies both during the downward travel time of the spray header member and its upward travel time. The spray impinges the assemblies at a forty five degree angle. Depending upon the cycle being undergone, the nozzles discharge a caustic cleaning solution, domestic potable water, or a dionized water rinsing solution.

Abstract: A device for the removal and installation of bearings and hubs on all front wheel drive vehicles. The device comprises a main housing, a threaded rod guider, a bearing pusher, a bearing stopper, a push nut, a hub installer, a hub pusher and a guide lock nut. For the hub removal function, the device uses the hub pusher which exerts a pushing pressure against the hub to be removed. For the wheel bearing removal function, the device uses the bearing pusher which exerts a pushing pressure against the wheel bearing to be removed. For wheel bearing installation function, the device uses the bearing pusher which exerts a pushing pressure against the bearing to be installed. For the hub installation function, the device uses the bearing pusher which exerts a pushing pressure against the hub to be installed. To perform these functions there is no need to remove the wheel bearing housing from the vehicle. Also there is no need for major disassembly of adjacent parts or disturbance of front end alignment.

Abstract: An improvement to a drill bit sharpening apparatus in the form of a simple spacer that provides the space setting between a drill bit point and the surface of a grinding device. The spacer comprises an elongated strip made of hard material; the width of the strip is not uniform and diminishes at two portions of the strip. The slanting angle of the portions corresponds to the Z-distances travelled by a drill bit supporting member so as to accomplish the setting. The strip also has calibration marks on its surface corresponding to a set of drill bit diameters for a given point angle. The spacer completely replaces the disc shaped and rectangular shaped prior art spacers.

Abstract: An apparatus for continuously removing waste materials from a water stream. The apparatus includes a rotating screen assembly formed by a plurality of articulated "L"-shaped links that form separate, laterally spaced closed loops. The space between the loops of links defines the maximum size of material that can pass through the apparatus without being removed from the stream. The respective truncate portions of the "L"-shaped links facilitate the lifting of the debris from the stream. The screen assembly is rotated by motor-driven sprocket segments that are positioned at the discharge end of the apparatus. These segments substantially occupy the spaces between the links when the links travel past the segments, and the occupation of the spaces by the segments displaces the waste materials from the spaces and dislodges the materials from the links as well so that the materials may fall under the influence of gravity to a receptacle.

Abstract: A four function vital sign monitor. The apparatus provides a display showing a person's temperature, respiration rate, pulse rate and blood pressure. The apparatus is specifically designed to provide accurate systolic and diastolic measurements for persons having healthy, flexible arteries or unhealthy, rigid arteries, or having unusually low blood pressure as a result of trauma or other shock-inducing event. A blood pressure cuff applied around any extremity transmits cuff pressure signals, for blood pressure and pulse rate computation, to a pressure transducer housed in the monitor. The versatility of the apparatus resides in its provision of a plurality of devices having different levels of sensitivity so that pressure pulses of differing amplitudes transmitted by the pressure transducer are detected by different ones of such detecting devices.

Abstract: A long-lifetime light source with sufficiently low intensity to be used for reading a map or other writing at nighttime, while not obscuring the user's normal night vision. This light source includes a diode electrically connected in series with a small power source and a lens properly positioned to focus at least a portion of the light produced by the diode.
