Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a hand-held firearm comprising a muzzle silencer and a barrel which is provided with transverse bores and is surrounded by an expansion area into which the transverse bores extend.  The transverse bores enable the muzzle velocity of the bullets to be less than Mach 1, in spite of the use of conventional ammunition, and there is consequently no supersonic boom of the bullet.  To selectively eliminate the reduction in firing energy involved therein and be able to shoot with maximum firing force, the transverse bores are selectively closable by a locking device which is preferably in the form of a sleeve which surrounds the barrel and is mounted for rotation thereon and is furthermore provided with an actuating member for setting the open or closed position.  The actuating member may take the form of a tube section surrounding the barrel in spaced relationship thereto at least over part of its length and delimiting the expansion area, with its both ends connected with the barrel in sealed relationship and mounted on the barrel for rotation. The tube section is connected with the sleeve for rotation therewith.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for electrically testing a multi-core cable comprises a pick-up unit for picking up cores individually from a group of cores at one end of the cable. The conductor wires of the cable are collectively electrically interconnected by a contact gripping device at one end of all the conductor wires, the opposite ends of which are immersed in a conductive liquid in a vessel at the other end of the cable.  The conductor wire of each picked up core is electrically separated from the other cores and power is supplied to the picked up conductor wire so that a current flows through the picked up wire through the conductive liquid, conductor wires of other cores and the contact gripping device to the ground.  A determining circuit determines in response to the current that any picked up core is in a discontinuity state when the current is less than a first value and that an insulation breakdown has occurred between any picked up core and any other core of the cable when the current is greater than a second value which is greater than the first value. Thus, both discontinuity testing and defective insulation testing are carried out simultaneously by the present apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE         A multi-mode solar heat recovery device for use at an interior surface of a window.  The device includes heat conductive plates for heat absorption of sunlight, reflected from corres-ponding light reflective surface.  Each heat conductive plate includes heat conductive tubing and carrier fluid to convey the heat from the plate to a point of heat utilization, such as a water heater or space heated.  Regulation of the heat recovery device is provided by automatic adjustment of the light reflective surfaces to variable orientations with respect to the incident sunlight and heat conductive plates.  This vari-able orientation permits selection of (i) essentially complete light blockage when adjusted to a closed position, (ii) maximum light reflec-tion to a heat absorbing surface when at an intermediate position and unobstructed transmit-tance of light when in a fully opened position.   The heat recovery device is further adapted with a convection heat collector which may be utilized as a cooling device.  The solar heat recovery device and convection heat collector may also be used collectively as part of an overall temperature control system which includes two water storage tanks and heat utilization.  Furthermore, this system to complement the heat recovery system.

Abstract: ABSTRACT   The invention described is a test method and testing kit used in the detection and quantitation of complement fixation antimicrobial antibodies,  such as antiviral antibodies, in human or animal serum samples. The test procedure utilizes Staphylococcal protein A-coated red blood cells immobilized in a gel into which is encorporated a specific microbial antigen. Undiluted heat inactivated serum samples are allowed to diffuse radially from wells punched in the solidified gel. Protein A serves to concentrate the subsequent antigen-antibody reaction on the surface of the red blood cell. Zones of hemolysis are developed by flooding with complement. The diameter Or the zone of hemolysis is proportional to the concentration of specific antibody in the serum. Using adenovirus as a model, basic test parameters have been defined and optimum reagent concentrations and diffusion conditions have been determined.

Abstract: PROCESS FOR FABRICATING AN OPTICAL DEVICE            Abstract This invention is a process for fabricating optical devices by photoetching geometrical shapes on the surface of an n-type or intrinsic compound semiconductor so as to yield surfaces of optical quality without further processing.  The etching process is an electrochemical process where etching is proportional to light intensity. The process involves applying a potential to the compound semiconductor while immersed in an electrolytic solution containing hydrofluoric acid and irradiating the surface to be etched with light in a certain energy range.  The distribution of light intensity and ray direction is selected to produce the desired geometrical shape. Particularly advantageous is that the surfaces produced are of optical quality.  For example, lenses produced by the etching process exhibit surfaces of optical quality. Further, the process can be carried out on all the lenses on a wafer simultaneously without attention to individual devices.  This is highly desirable economically.  Also, the lenses produced are integral parts of the light emitting diode.

Horrobin thus proposed that inter alia a GLA supplement should be given to cancer patients receiving conventional treatment, in order to test his hypothesis, namely, that in bypassing the metabolic block caused by an inhibited delta-6-desaturase (d-6-d) activity, it should be possible to normalise cancer cells by reverse transformation.

Abstract: Abstract An arbitration technique is described for use in conjunction with a parallel bus structure. Essentially, it involves the use of a Request signal instead of an Acknowledge signal as the propagated polling signal and making use of the delay elements in each bus unit, which act in parallel with poll propagation and with each other to reduce the net poll propagation time.  Making use of the Request signal allows initiation of arbitration prior to the activation time of the Acknowledge line.
