Abstract: ABSTRACT OF THE DISCLOSURE     To improve reliability of recognition of an announcement recognition (AR) signal radiated by a transmitter upon broadcasting an announcement (e.g. traffic information, news, etc.) in the form of AM modulation of a 57 kHz auxiliary subcarrier, in which the subcarrier is essentially continuously modulated by region or radio-station recognition signals, the level of which changes when the announcement recognition signal is radiated, the subcarrier is filtered in the receiver, demodulated, and the degree of modulation by the frequency characteristics of the region or radio-station recognition frequency (RR) is sensed.  If the modulation of the subcarrier at this frequency or frequency band (RR) drops from, for example, 60% modulation to 30% modulation, or  less - a 50% level change - a switch (4) is activated which inhibits transmission of audio programs from an external source, such as a tape recorder (5), a tuner tuned to another station, or the like, and reproduces the program or announcement being broadcast by the station to which a  region or radio-station recognition frequency is assigned.  Termination of the AR signal (Fig. 3: t2), forming the AR modulation on the 57 kHz subcarrier, causes the switch (4) to revert for reproduction  of previously controlled audio information upon increase in the level of the RR modulation on the subcarrier, which is sensed in a modulation sensing circuit of network (Fig. 2: 34-37).

Abstract: ABSTRACT OF THE DISCLOSURE   "PORTABLE PULSED NMR INSTRUMENT AND METHOD OF USES"               In accordance with the present invention, fluid-flow properties of a rock sample based on NMR response of the hydro-gen nuclei of interstitial fluids within the pore space of such sample, can be swiftly and accurately achieved using a portable NMR instrument. Inherent instrument inadequacies (DC field inhomogeneity and large phase background jitter) are themselves relied upon to increase the data-throughput efficiency, i.e., the number of NMR responses performed per unit time. Result: Even though the instrument is placed at field sites away from the usual processing center, quick analysis of rock samples as during the drilling of a well, still results. Also, effects of possible echoes during subsequent measurements are prevented by using both the inhomogeneities of the DC field and the essen-tially random phase spectrum that is inherent in the instrument to average out echoes of prior generated NMR responses .

Abstract: ABSTRACT OF THE DISCLOSURE There is disclosed a technique for tightening threaded fasteners in which values of offset torque, initial tension rate relative to angle advance, final tension rate relative to angle advance and other joint related factors are empirically determined by instrumenting a plurality of fasteners of the type ultimately to be tightened.  In one embodiment, torque and angle of advance are monitored during the tightening of production fasteners.          Calculations are conducted, while tightening, of the ratio of the torque and the torque rate of the fastener being tightened to determine the tension prevailing in the bolt at a particular angle of advance.  By using the calculated tension value and the particular angle of advance, an instantaneous position of thread-ing advance on the tension-angle curve of the fasteners is established.  From this instantaneous position, it is determined how much greater angle of advance or how much torque is required to tighten the fasteners to a final desired tension value.  The same technique is also used merely to monitor tightening which is terminated by a different tightening strategy.  In another embodiment, analog devices are utilized to convert sensed values of torque and the rate of threading advance into parameters which control tool shut off.

Abstract: Abstract A high voltage fuse having mounted gas evolv-ing members and method of forming such a fuse are disclosed.  The high voltage fuse comprises, in part, a plurality of block shaped gas evolving members attached to a plurality of fuse elements, which, in turn, are wound about a supporting core. The high voltage fuse also has an electrically insulating casing in which is mounted the core having the wound fuse elements and the attached blocks of gas evolving members.  The fuse casing is filled with a pulverulent arc quenching filler material.  The block shaped gas evolving members have a narrow slit which allows the gas evolving members to be easily slipped over the fuse element so as to cover part or all of a transverse portion of the fuse.  The gas evolving members are positioned over the fuse element at locations along the core so that the block type gas evolving members are arranged between adjacent portions of the ribs of the core. The block type gas evolving members are further positioned in desired locations by disposing the gas evolving members between the adjacent turns of the fusible elements.  Positioning the gas evolving material blocks at their desired locations provides stationary boundaries and limits the movement of the gas evolving material during the filling of the fuse casing by the pulverulent arc quenching filler material.

Abstract: ABSTRACT   An elongated stamped sheet-metal slider member facilitates the alinement and support for the guiding pulley of a band saw.  The slider member has several integrally-formed portions.  A first portion depends within the housing, and the pulley is rotatably supported thereon about an axis substantially perpendicular thereto.  A second portion of the slider member is bent away, forming an obtuse angle with the first portion, and extends through a slotted opening formed in the housing.  This second portion has a pair of ears projecting laterally of the slotted opening for preventing the slider from passing completely into the housing.  The ears have respective side edge portions engaging the outer surface of the housing and forming therebetween a fulcrum for pivotal movement of the slider member and hence the pulley about an axis which is above the pulley axis and transverse thereto.  A jack screw is carried by the housing for engaging the first portion of the slider member below the pulley axis.  Movement of the jack screw pivots the slider member and hence the pulley about the pivot axis of the slider member, thereby facilitating an alinement of the guiding pulley.  A third portion of the slider member is bent back into the housing above the fulcrum and within a plane substantially at right angles to the plane of the first portion of the slider member.  A cap screw is secured at its lower end to the third portion of the slider member, and the head of the cap screw is captured by a tensioning knob for supporting the slider and hence the pulley within the housing.          By means of the tensioning knob and cap screw, the slider member may be raised and lowered vertically within the housing, and thus the pivot axis of the slider member will be adjusted vertically.  In addition, a suitable spring is provided to tension the assembly and hence the guiding pulley, and as a result the pivot axis of the slider member will float along the outer surface of the housing.

Abstract: Abstract of the Disclosure Packing tubular membranes or membrane channels for Ion Chromatography with inert particles greatly increases overall suppressor efficiency.  The length of membrane required is reduced, e.g. from 20 feet to 5 feet and bandspreading is reduced from 870µl to 200µl.          This significant increase in efficiency is attributed to the mixing action of the packing on the flow stream which results in convective radial transport much more rapid than the diffusion controlled transport observed in unpacked membranes.  The technique is also described for developing more efficient liquid chromatographic post-column reactors for adding reagent to the column effluent to increase detection sensitivity.

Abstract: ABSTRACT             Expression Vectors There are described a number of plasmid vectors suitable for the expression of genetic material, at various levels in yeasts.  The plasmids each comprise a yeast selective marker, a yeast replication origin and a yeast promoter positioned relative to a  unique restrict-ion site in such a way that expression may be obtained of a polypeptide coding sequence inserted at the restriction site.  The promoters used are derived from the 5' region of a gene coding for a yeast glycolytic enzyme e.g. phos-phoglycerate kinase (PGK), or from the 5' region of the yeast TRP1 gene.  In one Example a plasmid contains a promoter derived From both the 3' and 5' regions of the PGK gene.  The replication systems used involve the yeast 2? replication origin or  an autonomous replicating sequence (ARS) stabilised with an ARS stabilising sequence (ASS).  The replication systems allow for a choice of high or low copy number per cell.  The promoter sequences allow for a choice of high or low expression level.  A kit including vectors having a combination of these alternative features is described.  Yeast expression vectors including a gene for coding for human interferon-?are described.

Abstract: ABSTRACT OF THE DISCLOSURE      An adjustable jig assembly for holding a work piece in a desired position, comprising a stand having wall members defining a pair of opposed substantially vertically extending slide channels, mounting means slidable in the slide channels for fixedly mounting therebetween an axially rotatable retaining means in desired vertical and axial orientation, and a work piece engaging member adapted to be fixedly retained by the retaining means in desired orientation about an axis normal to that of the axially rotatable retaining means.  The adjustable jig assembly is particularly useful in manufacturing replacement flanged pipes due to the criticality of reproducing the exact spatial orientation of the flange members.  Present practice requires that individual jigs be custom made for each flange and that the individual jigs be identifiably coded so that they can be reused during a stress relieving treatment subsequent to welding and machining operations.  Disadvantages of the present practice include unnecessary wastage of time and material to custom make the individual jigs, the necessity of identifiably coding the individual jigs and the potential necessity of transporting the individual jigs to different work sites since welding and stress relieving are frequently carried out in separate locations.

Abstract: REACTION METHOD AND REACTOR THEREFOR            Abstract of the Disclosure:         Disclosed herein are a method for carrying out a catalytic chemical reaction in the presence of a granular catalyst under conditions such that both the reactants and the reaction product are gaseous at the temperature and pressure of the reaction, and a reactor useful for practicing the above method.  According to the present invention, a vertically extending, annular, intercylinder space, defined between a cylindrical outer catalyst retainer and a cylinder inner catalyst retainer, is divided by radially extending vertical partition walls into a plurality of chambers.  Heat-exchanging tubes are disposed vertically in at least one of the chambers.  A granular catalyst is packed in at least two of said chambers to form at least two reaction chambers.  A feed gas is caused to flow successively and in radial direc-tions through these reaction chambers.  Since the inven-tion reactor achieves an improved linear gas flow velocity and a greater overall heat-transfer coefficient, the reactor of the invention requires fewer heat-exchanging tubes and can thus be made smaller.  The optimum temper-ature distribution for the reaction can be attained in each reaction chamber.
