Abstract: CASTER AND SWIVEL LOCK ASSEMBLY                      ABSTRACT              A self-aligning swivel caster for use on carts and the like, the caster being equipped with a member for locking and releasing the caster with respect to swivel move-ment.  The locking and releasing member, which can selectively be oriented in an operative or an inoperative position, is friction and gravity actuated.  The strucutral relationship of the caster and the member is such that automatic camming and actuation of the member occurs as the caster is swiveled from an unlocked position into a locked position or from a locked position into an unlocked position.  During actuation of the locking and releasing member, the caster makes direct contact with the member until the member finally drops into the proper position to either restrict or facilitate further swivel movement of the caster.

Abstract: Abstract of the Disclosure Method and apparatus is described for remote detection of location and intensity of clear air turbulence through the collection and analyses of back scattered laser light from a region where clear air turbulence may exist.  The interference pattern of the collected light is determined through an ultra high resolution spectroscope and is analyzed with an image dissector.  Information from the image dissector relating to the spectrum of back scattered light is correlated with the standard spectrum representing absence of clear air turbulence at the distance in question.  By providing apparatus having high sen-sitivity and fast response, a device suitable for use in aircraft to detect clear air turbulence is provided.

Title: Process for recovery of copper and zinc from complex sulfides
Inventor: WEIR DONALD R
IPC: C01G3/12
Filed: 1977-08-19
Granted: 1981-07-14
Abstract: ABSTRACT         A process for treating thermally activated metal sulfides containing copper, iron and zinc for separate recovery of zinc as zinc sulfide in which the metal sulfides are subjected to a two-stage countercurrent acid leach for the formation of copper sulfide containing acid leach residue and ferrous sulfate solution.  The second-stage acid leach is performed in two steps;  the first step is operated at a relatively high pulp density and high acid concentration for iron and zinc extraction, the resulting slurry diluted, and the second step is operated at a relatively low pulp density and low acid concentration for dissolution of precipitated ferrous sulfate and precipitation of any dissolved copper values by H2S.  The diluent solution for the slurry from the second-stage first step preferably is generated sulfuric acid solution from a jarosite precipitation and iron and zinc-containing solution from a subsequent activation leach.  Zinc in solution from the acid leach and activation leach is precipitated as zinc sulfide in substantially pure form.

Abstract: Abstract of the Disclosure A water play toy comprising a base portion and an elevatable, elongated upper portion having a water deflector mounted at the top.  A source of water under pressure is coupled to an upwardly directed nozzle located in the base portion.  When the water pressure is turned on, a jet of water is directed upwardly from the nozzle through the upper portion to the deflector and the force of water lifts the upper portion into the air where it balances on the head of the water stream.  When the deflector is an impeller, the upper portion rotates and an umbrella-shaped shower of water is broadcast outwardly from the deflector.  As long as the water pressure is uninterrupted, the upper portion is balanced on the top of the water stream from the nozzle and continues to spray water in a circular pattern around the toy.  The nozzle is slidably positionable to enable it to be positioned to direct the water stream directly vertical.

Abstract: ABSTRACT      An apparatus in a digital communication system having the capability for transmitting or receiving a partial byte in the final byte position of the information field.  Thus, a non-byte-oriented message may be blocked into bytes of any convenient size, and the final bits, if they do not completely fill up the final byte, can still be accommodated using the partial byte capability.  The size of the final byte is indicated by adding a pointer bit to the character in memory.  The partial character is right justified in its byte and a one (i.e. pointer bit) is inserted immediately to the left of the character and zeros are filled to the left to complete the byte.  This byte is placed in a transmit register; a partial byte is shifted to the right until a pattern of all zeros and a one remain in the register; this pattern is recognized by the hardware and indicates that the end of the partial byte has been transmitted.  For received data, the process is reversed.

Abstract: ABSTRACT OF THE DISCLOSURE      A control system is provided for a hydraulically operated tractor hitch assembly including a rockshaft operated by a main cylinder which is controlled through a spool valve operated by a pilot cylinder which is controlled, in turn, through a solenoid operated pilot valve. The pilot valve is controlled in response to a command signal and first and second feedback signals which correspond to the position of the rockshaft and to the position of the spool valve member. The velocity of the downward movement is limited by limiting the amplitude of a firs error signal which is developed by a first comparator responsive to the command and first feedback signals with the firs error signal and the second feedback signal being applied to a second comparator. Such velocity-limiting operations are controlled through a manually operated switch or by a motion sense circuit responsive to the rate of change of the command signal. A command signal which has a fixed magnitude corresponding to a fully raised position is applied in a raise position of a raise-lower switch or in a transport lock position of a control lever. Error detector means are provided for sensing loss of the first feedback signal and for applying a signal to cause centering of main valve to lock the hitch against movement.

Title: Fiber optic interface for combined signal transmission and detection

Granted: 1981-08-18
Abstract: ABSTRACT OF THE DISCLOSURE               A fiber  optic interface for combined signal trans-mission and detection is provided.  The interface enables transmission in two directions over a single optic fiber and includes a housing having an elongated channel extending therethrough.  The housing is comprised of a transparent material.  A first optic fiber is secured in one end of the channel with the outermost end of the first optic fiber being aligned with a light source.  A second optic fiber is secured in the other end of the channel with the innermost end of the second fiber being disposed adjacent the innermost end of the first fiber.  The ends of the fibers are mismatched so that there is a loss of light passed from at least the second fiber to the first fiber during a light transmission from the second  to the first fiber.  A light sensitive device is secured to the housing and is responsive to light escaping at the junction between the first and the second fiber ends.  The mismatching of the fiber ends is accomplished in two ways.  The first is the provision of a smaller diameter optic fiber which is connected to the light source than the optic fiber connected to the remote light source.  In this way substantially all of the light provided by the light source connected to the first optic fiber is passed to the optic fiber connected to a remote light source.  However, in a transmission from the remote light source to the local interface, there is a loss of light about the periphery of the first optic fiber which enables the detection device to pick up the signal.
