Abstract: ABSTRACT OF THE DISCLOSURE A two-piece child-resistant closure comprises nested inner and outer closure members.  Sets of lugs on an inner surface of a panel of the outer member and an outer surface of a panel of the inner member engage each other when the outer members rotated for application of the closure to a container, but cam past each other on inclined surfaces when the outer closure is rotated in a removal direction.  The panel of the outer closure member is resiliently deformable to bring the non-camming surfaces of the lugs into engage-ment for removal of the closure.

Abstract: Abstract of the Invention A rigid, earth-contacting target for use with an acoustic signal generator is designed to be impacted by a mass propelled downwardly by compressed air or other energy source.          The target includes an upper impact-receiving member slidably interfitted with a lower ground-contacting member.  An elasto-meric disc is confined between the upper and lower members so as to experience three-dimensional compression in response to such impact.  The bulk modulus of the elastomer determines the degree to which the rate of acceleration of the lower member is reduced as compared to that of the upper member, and thus in turn, controls the frequency content of the resultant acoustic pulse.

Abstract: ABSTRACT OF THE DISCLOSURE          The disclosure describes a method for measuring pressure, more particularly the stationary, or quasi-stationary, pressure of a fluid, with a pressure actuated measuring piston guided in a cylinder and communicating with a load measuring device.  According to that method the piston is guided in the cylinder, without contact, by means of hydro-static or pneumostatic lubrication with a separating fluid supplied under  pressure.  An apparatus to carry out the method is also disclosed.  The measuring device is capable of completely eliminating existing measuring uncertainties and cases where weighing is impossible.  More particularly, in weighing the pressure of a column of liquid as a basic factor in gravimetrical determination of quantities, the effect of temperature is eliminated and therefore need not be considered.

Abstract: ABSTRACT OF THE DISCLOSURE     According to this invention, the anaerobic treatment or purifica-tion, respectively, of waste water that contains furfural, and particularly the vapour condensate of the sulfite spent liquor thickening in wood pulp production in the presence of sulfate reducing bacteria and methanogenic bacteria can be initiated and controlled by the addition of furfural degrading bacteria.  Such furfural degrading bacteria were obtained by proceeding from a source for anaerobic bacteria, such as swamps or bogs, or more particularly sewage sludge, with intermediate enrichment in a continuous liquid culture with the addition of a solution that contains furfural by means of a special tech-nique, in which the bacteria (at various concentrations) are fixed in agar columns that are overlaid with a diluted solution of furfural, this serving as the sole source of carbon.  On diffusion in the agar a concentration gradient is formed, within which there exists in each case a concentration area that is suitable for the bacteria.  In this way, discus shaped, beige coloured indivi-dual colonies of furfural degrading bacteria are obtained.  These are highly mobile, slightly S-shaped curved flagellate rods, and are similar to Desulf-ovibrio gigas.

Abstract: ABSTRACT OF THE DISCLOSURE    An anchoring device for a prestressing location can also serve as a coupling location for tendons in prestressed concrete where a subsequent bond is provided for the tendons.  The anchoring device includes an anchoring member containing a plurality of bores divided into two separate groups, with each group arranged to anchor individual tendon elements extending into the anchoring member from an opposite direction.     Each bore has an axially extending frusto-conical section and a cylindrical section extending from the smaller diameter end of the frusto-conical section.  The frusto-conical sections in one group of bores are axially offset from the frusto-conical sections in the other group of bores.  The bores in one group are filled with a plastic corrosion protection material, such as grease.  Such corrosion protection material ensures a continuously active wedge-anchoring system which facilitates the movement of the wedges under full load conditions while providing a short bond-free length in the cylindrical section affording compensation for the time-dependent slippage of the anchoring device.  A similar arrangement of the anchoring device can be used as a coupling device along the length of a tendon.

Abstract: Abstract The rotary seal assembly is used for sealing a rotating shaft, such as the shaft of a centrifugal pump.  The assembly has a first sealing element fast on the shaft and d second sealing element arranged non-rotatably but axially movably next to the first element.  On that side of the elements towards the pressure fluid which is to be sealed, there is a barrier, and there is an inlet for pressurized service liquid into the annular space between the elements and the barrier.  The pressure of the service liquid forces the second element into sealing contact with the first and also provides a liquid barrier separating the elements from the pressure fluid which is being sealed. This feature is useful when abrasive slurries are being pumped, since the slurry is refused access to the elements.

Abstract: ABSTRACT OF THE DISCLOSURE            A method of position control by DC servomotor with improved stiffness is disclosed.  In the present invention, electric current (iR) of the servomotor is interpreted anew and given as follows:                    where .theta. is an observed rotation angle of the load (L), .theta.c is a precommanded value, KF is a feedback coeffi-cient, and KV is a velocity coefficient.  After normalizing the above equation, it was discovered that stiffness (S) can be increased by incorporating a limiter into the control system, thus providing prompt response and smooth convergence of .theta. to .theta.c with a high degree of stiffness maintained at the precom-manded angle (.theta.c).

Abstract: ABSTRACT OF THE DISCLOSURE     A torque limited threaded locking fastener and a method for setting it to form an assembly.  The fastener comprises an externally threaded shank and an internally threaded collar.  At least one convolution of the threads on the shank is non-circular.  The collar has a nut section and a drive section.  The drive section is shaped to be engaged by a driver.  Between these sections there is formed a shear section having the least torque resis-tance of the sections.  The shear section fractures when a predetermined torque is exerted between the two sections.  The nut section has an internal thread engageable to the shank thread, and an external rib engageable by a swaging tool.  The swaging tool radially inwardly deforms and displaces the rib so as to displace nut section material at the non-circular convolution whereby to lock the nut to the shank after, but only after, the drive section is torqued off.  The rib is proportioned and arranged so that the swaging of the rib to a lesser radial dimension does not change the torque level which was applied when the drive section was torqued off.

Abstract: Abstract of the Disclosure A sodium Y type faujasite having a high silica/alumina ratio is obtained by lowering the active soda content below the conventionally employed levels.  This is done by adding an acid and/or an aluminum salt solution such as an aluminum sulfate solution to the sodium silicate in the zeolite synthesis slurry.  Alternatively, the desired alumina and silica starting materials can be supplied in part by using an aluminum salt gelled mother liquor such as an alum gelled mother liquor.  This permits the use of less reactants which are high in soda such as sodium silicate and sodium aluminate which in turn reduces the amount of soda present.  The addition of these soda removers or the use of low soda reactants permits the production of NaY having a silica/alumina ratio of 5.0 and higher.  These Y zeolites have a high degree of crystallinity as measured by an NMR sharpness index defined herein and they have an absence of occluded silica.  The final product can be ion exchanged to a low level of Na2O with rare earth or other metal cations or ammonium ions, to make a more thermally and steam stable zeolitic promoter for catalysts for treating petroleum fractions than can be made from conventional sodium Y.

Abstract: ICING APPARATUS FOR PALLET SUPPORTED CARTONS            Abstract The icing apparatus comprises an open frame structure for receiving cartons stacked in rows and columns on a pallet.  These cartons contain perishable food such as broccoli brought in from the field and are to be treated with liquid ice to preserve their contents.  Towards this end, the apparatus includes left and right carriages carrying horizontal rows of liquid ice injecting probes or nozzles.  These carriages can move up and down left and right sides of the frame and also the probes themselves can be moved in and out towards and away from cartons on the pallet.  By this arrangement, an upper horizontal row of cartons can be simultaneously iced by the horizontal row of probes by simply moving the same into the hand hold openings of the cartons.          The carriage structures can then be lowered by the heighth dimen-sion of the cartons and a next horizontal row of cartons simulta-neously treated with liquid ice.  The process is repeated until all cartons on the pallet have been treated with liquid ice, the cartons then being removed while still on the pallet.

The derivative of R, R is calculated and stored and the function is divided by power P to obtain R/P.  The resistance curve is searched to obtain the maximum value Rm which occurs during the heating phase and the function R/P is searched prior to the time of Rm to find the maximum of that curve representing the highest rate of resistance increase.  Then the R/P curve is searched subsequent to its maximum to deter-mine when the function reaches a specified percentage of the maximum  That value occurs at the knee of the resistance curve and approximate the onset of melting in the weld.         A prediction of whether a weld is a nugget or a sticker is made by calculating the ratio of weld energy after the onset of melting to the total weld energy, the ratio of the resistance drop after the resistance peak to the peak resistance, and then a weighted sum of the energy ratio and resistance drop ratio.         An edge weld geometry is detected by calcu-lating from the resistance and power curves the weld energy during the period of expulsion, if any, divided by the cumulative energy between the onset of melting and the end of expulsion, a measure of expul-sion intensity based on the maximum degree of resis-tance inflection, and then a weighted sum of the energy value and the inflection value.
