Abstract: ABSTRACT OF THE DISCLOSURE     In a facetted gem of angular shape it is the usual treatment to fashion the stone in a step cut style, notably the emerald cut.    In the invention the embodiment is such that the rows of facets of the emerald cut and its variations are replaced by an arrangement of facets in a brilliant style, resulting in a higher degree of scintilation. This is achieved by the alignment of the main facets of the top and/or bottom with the corners of the stone and at elevation angles that are recognized as being ideal. This alignment is contrary to the customary palacement of facets on a stone of angular shape. The remaining subsidiary facets are positioned accordingly. The resulting cut meets the criteria and appearance of the fully brilliant style.

Abstract: ABSTRACT OF THE DISCLOSURE     A door strike for reinforcing a door jamb against forced entry has a stepped body which is designed to conform to the contour of the door jamb.  When the door strike is mounted, a first planar platelike landing portion of the body is positioned against the edge margin of the jamb.  This first landing portion defines a latch mechanism receiving opening though which a door mounted deadbolt or latch when the door is closed and locked.  A second planar platelike landing portion of the body is positioned against a central region of the jamb when the door strike is mounted.  In addition, an anchor rod projects rearwardly from this second landing portion, through the jamb, and into the center of studs which form the rough door opening so as to reinforce the jamb against forced entry.

Abstract: Abstract Device for simultaneous control of air flow and circula-tion speed for an air conditioning installation with variable air flow.         The device includes a pressure-reducing chamber arranged immediately upstream of an air conditioning dif-fuser.  It includes a shutter which pivots about an axis and which tends to reduce the useful area of the diffuser in question, under the action of a counterweight.   The air introduced into the chamber, by means of a normally open motorized damper, exerts on one of the faces of the shutter, a pressure which tends to oppose the effect of the counterweight and tends to increase the use-ful area of the diffuser.        A sensor which serves as a stop during the opening of the shutter, reacts on the motorized damper to tend towards a balance of the forces applied on the shutter, for a particular area of diffusion defined by the position of the sensor.        The displacement of the sensor, operated by an at ent thermostat for example, enables the variation of the airflow by changing the free area of circulation.        The speed of circulation is practically constant and depends on the counterweight acting on the shutter.

Further,  methods  are  provided  for  obtaining  from  microorganisms, including      dematiaceous      hyphomycetes,      non-heme-containing chloroperoxidases, which have the same halide-oxidation capabilities and pH optima and which are substantially more stable to inactivation by  H202 and HOCl  than the chloroperoxidase of  Caldariomyces fumago. The  chloroperoxidases  obtained  by the methods of the invention are used,  in  aqueous  solution  at  a  pH  between  about  4  and  9 in the presence of H202, to catalyze the oxidation of iodide to iodine and the  same  halogenation  reactions,  between  halide  ions  and  organic acceptor   compounds,   that   can   be   catalyzed   by   C.   fumago chloroperoxidase.

Abstract: ABSTRACT   1.   SELF-ADAPTING RETENTIVE ENDODONTIC BUILDUP-POST.        Core buildups of endodontically treated teeth the crowns of which are fractured, weakened, or destroyed by caries can be done in basically 2 ways:        - cast post and core - prefabricated posts with metal cores or cores in combination with acrylics.  Retention is achieved through cementation, threads on the post, or a combination of the two.  In order to achieve the best possible hold and to prevent stress of surrounding tissue, most prefabricated post systems re-quire preliminary precision drilling.  Due to the use of these cylindrical posts, two problems often occur.  First of all, in teeth which have tapered canals or slender roots, perforation of the canal wall can occur.  Secondly, in teeth with very large or very asymmetrical canal lumen, sufficient actual retention can be very difficult to achieve.  Although the treatment of choice in such cases is the cast post, in comparison to the pre-fabricated post it is work and time consuming.        The objective for my invention was the development of a pre-fabricated endodontic post that is simple and time saving, and can also be used in flaring or very oval canals without comprising the clinical strength or stability necessary for the core build-up.  I have named this the self-adapting retentive endodontic build-up post, hereafter called the S.A.R. Post.

Abstract: ABSTRACT A computing means is provided which has its instruction execution synchronized to a reference signal. The computing means executes instructions in instruction cycles synchronously related to a clock signal. The clock signal is generated by means which can control its phase and frequency in response to a control signal. The computing means generates a comparison signal each time a predetermined number of instruction cycles have occurred. A comparison means compares the phase and frequency of the comparison signal to that of a reference signal from a source and generates the control signal in response. Alternatively, characters are displayed on the image display device of a television system by means of a microprocessor. The microprocessor is embodied on an integrated circuit and executes instructions in instruction cycles in time relationship with a clock signal. The clock signal is generated by means which can control its phase and frequeny in response to a control signal. A synchronizing means generates the control signal in response to the clock signal and a television synchronizing signal from a source so that the instruction cycles are synchronized with the television synchronizing signal. The microprocessor generates character pulses at a rate proportional to the instruction cycles from data signals corresponding to the character from a source. Means couple the character pulses to the image display device to display the characters.

Abstract: ABSTRACT Method and device for determining an NMR distribution in a region of a body.     The method and device for NMR Fourier zeugmatography utilizes amplitude-modulated r.f. pulses (90° and 180° pulses) for the excitation of nuclear spins and the generating of nuclear spin echo signals. For three-dimensional Fourier zeugmatography r.f. pulse having a large bandwidth (for example 10 - 50 kHz) are desired. The use of amplitude-modulated signals then implies an undesirably high peak power of the r.f. generator. In accordance with the invention, use is made of a frequency-modulated signal which can have a substantially constant amplitude and which preferably covers the desired frequency spectrum at a uniform speed.
