Abstract: ABSTRACT          A do-it-yourself spiral staircase with a central column from a hollow steel tube, which extends between a base on a lower floor and a landing plate or end tread on an upper floor of a dwelling or office building. On the central column are arranged individual treads between which spacer sleeves can be arranged. The steel tube is divided into two tubular sections, of which one portion is arranged for shortening on site to adjust the total height of the spiral staircase to the desired length, while the other part is fixedly secured with a short tubular sleeve, which is telescopically connectable with the shortened end of the other part. In order to fixedly secure the telescopically interengaged tubular portions, at least one bore is provided which passes perpendicularly to the tubular parts. Into the bore is engaged  under pre-stressing a highly tempered locking pin or a split sleeve under elastic pre-stressing.

Abstract: ABSTRACT       "PHOTOACOUSTIC ROTATIONAL RAMAN SPECTROSCOPY"         A method and apparatus for spectroscopic material analysis are provided.  Two coherent beams of monochromatic radiation are directed through a sample of material.  A tuning mechanism adjusts the frequency difference between the radiation beams to equal substan-tially the rotational frequency of a preselected con-stituent of the material.  Molecular energy of a preselected constituent of the material is increased, thereby producing a detectable signal in the form of a pressure wave.  The signal is received by a detecting mechanism which indicates the magnitude thereof.

Abstract: RUBBLE MINING ABSTRACT OF THE DISCLOSURE The invention disclosed herein relates to solution mining soluble ore deposits by creating a cavity substantially entirely filled with a deep bed of rubble.  Solvent introduced at the top of the cavity is permitted to percolate downwardly through the rubble and is withdrawn near the bottom of the cavity.  More specifically, the invention relates to selective solution mining generally horizontal beds of sylvinite, i.e., a mixture of crystals of halite (NaCl) and sylvite (KCl) wherein water or salt brine is washed down a generally vertical bore hole into the deposits and recovered enriched with dissolved KCl.

Abstract: ABSTRACT    A differential thermocouple combustible gases detector is provided by coating one thermocouple junction of a differential thermocouple pair with a catalyst and the other thermocouple junction with a non-catalyst.  Heated combustible gases react with the catalyst to liberate heat to the catalyst coated thermocouple junction in proportion to the concentration of combustible gases and proportionally raise the temperature of that junction above the non-catalyst coated junction.  The out-put signal from the differential thermocouple device is thus a signal indicative of the concentration of combustible gases.

Abstract: TITLE OF THE INVENTION:            STRAIN GAGE PICK-UP AND METHOD FOR ADJUSTING SUCH STRAIN GAGE PICK-UP            ABSTRACT OF THE DISCLOSURE:     Off-center load applications to strain gage pick-ups or transducers are substantially compensated by re-ducing  the off-center load application sensitivity of such transducers.  This is accomplished by providing the strain gage of the transducer with additional strain gage components which are so located that the effective position of the strain gage device is shifted on its supporting spring body.  Thus, although the strain gage device remains physically in position on the supporting spring body, the center of the coordinate system which defines the ordinate of the system can be shifted in any one of the four directions of the system.  If the spring body is equipped with a single strain gage only then the point of load application should lie upon the ordinate of the coordinate system what can be achieved by that shifting.  If the spring body is equipped with more than one strain gage then the symmetry of the whole strain gage circuitry can be improved by shifting of the respec-tive strain gage coordinate systems.

Title: Arrangement for synchronizing the phase of a local clock signal with an input signal
Inventor: JANSEN GERARDUS L M
IPC: H03L7/06
Filed: 1981-01-22
Granted: 1983-10-25
Abstract: 11 PHN. 9677 Synchronizing the phase of a locally generated clock signal with the phase of an input signal is usually effected by using a phase-locked loop, but this has a drawback that a certain run-in time is necessary to be sure that the phase of the clock signal is stable. The present arrangement comprises a delay line having taps, the delay line being driven by a crystal oscillator. Clock signal versions Cl(0), Cl(90), Cl(180) and Cl(270) which are phase shifted relative to one another through 90.degree. are available at the successive taps. A coincidence detection circuit comprising trigger circuits and a combining network detects the version of the clock signal whose ascending edge, for example, is located nearest to an ascending edge of the data signal, and this version is supplied as the clock signal at an output by the selective control of switches by control signals from the outputs of the network.

Abstract: ABSTRACT OF THE DISCLOSURE In an exemplary embodiment, two clamping parts which are mounted pivotally about a shaft for movement oppositely relative to one another in the manner of tongs, have a spring therebetween which compresses the clamping ends of the clamping parts for the purpose of clamping engagement with an electrode or the like.  Manual gripping portions disposed on the other side of the pivot shaft from the clamping ends, are manually compressed for the purpose of open-ing the clamp connection, at least one of the manual gripping portions receives a conductor which electrically connects with at least one of the clamping ends. It is the object of the disclosure to create a contact clip which is optimally ensured against breakage and which simultaneously presents no problems regarding cleansing.  This object is achieved in that the gripping portions of the clamp-ing parts are provided with one cavity each, which cavities during pivotal move-ments of the clamping parts, movably interengage whereby, simultaneously, in every clamping part position between the clamped and open state, extensive seal-ing-off of the interior space toward the exterior is guaranteed due to the interengaging cavities, and that a spring for spreading the gripping portions to be manually operated is seated inside these cavities.

A pivotable throttle member is positioned in the throat intermediate its opposite ends and is pivotable between a fluid flow restricting position and an open position.  The pivotable throttle member includes a cam surface. The carburetor is also constructed such that an increased number of the openings supply fuel to the throat as the throttle member pivots from a fluid flow restricting position to an open position and the openings are closed as the throttle member pivots from an open position to a fluid flow restricting position.  This is accomplished by a sleeve surrounding the tube and supported for slideable movement on the tube, and a cam follower engaging the cam surface, the cam follower carrying the sleeve whereby the sleeve is slideable on the tube in response to movement of the cam surface with respect to the cam follower.

Abstract: ABSTRACT OF THE DISCLOSURE      An alarm clock has a cambered leaf spring traversed by a nest of clock-hand shafts projecting from a mounting plate designed as a printed-circuit board.  The leaf spring is sup-ported at opposite ends by posts rising from the mounting plate and is limitedly swingable about a centerline parallel to that plate and perpendicular to the axis of the nested shafts.  A toothed control disk centered on the same axis, with a hub car-rying an alarm hand, is axially shiftable under pressure of the cambered leaf spring upon alignment of a tooth on that disk with a notch in an adjoining hour wheel; two diametrically op-posite metallic contacts formed by lateral tongues on that spring then engage respective countercontacts on the mounting plate to close a circuit for the  emission of an  acoustic alarm signal.  The alarm circuit can be broken by a manually displace-able interrupter lifting one of these tongues off its counter-contact; with a modified alarm circuit, closure of one or the other contact pair can be selectively inhibited to enable the alternative operation of  a buzzer or of a radio receiver upon displacement of the control disk by the leaf spring.
