Abstract: ABSTRACT OF THE DISCLOSURE       The disclosure describes a method for determining the half-lifetime (? 1/2) of a potential mutagenic agent in a cell culture environment.  According to this method there is first formed a culture of living cells, the cells being a tester strain for mutagenesis.  Then a spot of test agent in known concentration is applied to the culture whereby said test agent diffuses outwardly from the spot to form a ring-shaped mutagenic band in which viable mutant cells are produced, the ring-shaped mutagenic band being concentric to the spot of test agent.  The length of a radius extending from the center of the spot to the outer perimeter of the ring-shaped mutagenic band is measured.  The above steps are repeated a sufficient number of times with different initial concentrations of test agent to allow a plot to be constructed relating the initial concentration of agent to the length of radius measured.  The method also involves constructing a plot relating the initial concentration to the length of the radius measured for a plur-ality of initial concentrations, and determining the slope of the plot as an indication of the half-lifetime of the agent.

Abstract: TITLE:  PIPE HANGER CAPABLE OF TOTALLY ENCIRCLING         A PIPE                     ABSTRACT    A pipe clamp is formed with a body and the body includes a wall.  The wall is formed as a loop which completely surrounds an aperture except for an inter-stice opening through the wall into the aperture.  The portions of the wall located on either side of the inter-stice forms first and second wall ends.  The body also includes a foot joined to the wall.  A discontinuous passageway passes through the first and second wall ends and through the foot.  This passageway is capable of re-ceiving an object such as a nail.  The size of the nail utilized is such that its length is greater than the length of the passageway such that when the nail is lo-cated within the passageway a portion of the nail is cap-able of holding the first and second wall ends together in fixed association and a further portion of the nail is capable of extending out of the passageway beyond the foot.  The portion of the nail extending out of the pas-sageway beyond the foot is capable of being driven into a support surface to hold the body to the support surface when the foot of the body is abutted against the support surface.  The portion of the nail holding the first and second end walls together is capable of maintaining a pipe fixedly held within the hanger.

Abstract: ABSTRACT OF THE DISCLOSURE          An instrument for applying clips to a surgical site has an applicator with two jaws which are movable between open and closed positions.  A mechanism is provided for feeding the respectively leading clip of a string of such clips between the jaws, whereupon the jaws are closed and the leading clip is cinched as it is being applied to the surgical site.  To vary the presentation of the clip, i.e., its orientation relative to the surgical site, the mechanism is mounted so that it can turn about a longitudinal axis of the instrument.  In one embodiment, a slide button is provided which can be slid forward and back-ward with one finger of a user, such translatory movement of the button being converted into a turning movement of the mechanism and consequently also of the clip which is being held between anvils preparatory to its application to the surgical site.  In another embodiment, turning movement is effected by rotating a knob secured to the mechanism.  The instrument permits variations in the presentation (orientation) of at least the leading clip of a string of clips relative to a surgical site without requiring concomitant change in the orientation of a user's hand holding the instrument.

Abstract: ABSTRACT OF THE DISCLOSURE           An inductor alternator of the type used in a motor vehicle is combined with throttle control apparatus having a vacuum diaphragm that is communicable via a solenoid operated vacuum valve with the intake manifold of the vehicle engine and is operated thereby to actuate linkage connecting the diaphragm to the throttle of the engine carburetor.  A function switch selects one of two operating modes, the first providing a regulated do voltage output for battery charging and the second providing an unregulated do voltage output that varies directly with engine running speed and which is suitable for arc welding, battery boosting or powering small resistive appliances, floodlights and the like.  In the first mode the vehicle's battery is connected to the do output of the alternator via a solenoid switch but is disconnected in the second mode to prevent damage by an overvoltage.  In the second mode, the output voltage is available at either a polarized  receptacle or via a pair of welding cables.  A local switch actuates the vacuum valve to increase engine speed in the second mode to obtain a fixed output voltage suitable for appliance operation whereas a remote control switch on a welding rod holder runs up engine speed to develop a welding voltage only for as long as the switch is held closed.  When released, the engine speed drops to a preset minimum, thereby economizing on fuel consumption.

Abstract: This machine comprises at least one grinding unit mounted to a grinding base. Each unit comprises a frame secured to the grinding base. The grinding wheel is driven by an electric motor, suspended from the frame by means of four rocker arms constituting two parallel-motion suspension systems. The lower rocker arms are levers of the first order and the grinding pressure is applied for one of the rocker arms by the piston rod of a hydraulic cylinder rigid with the frame and adapted to position the grinding wheel in relation to the rail, and for the other rocker arm by the piston rod of a pneumatic cylinder also rigid with the frame. This pneumatic cylinder determines the operating pressure of the grinding wheel on the rail. The operative face of the grinding wheel is parallel to the plane of the theoretical tangent to the rail profile. A right-angled lever is pivoted to a projection of the frame and provided at one end with a stud facing the grinding wheel. During the forward feed of the grinding wheel this stud moves from an inoperative position to the theoretical tangent and when this theoretical tangent is attained by the wheel the opposite end of the right-angled lever actuates a device for stopping and locking the feed of the grinding wheel by actuating the hydraulic positioning cylinder.

Abstract: ABSTRACT:           The invention relates to an EPROM or an EEPROM in which the information is stored in the form of elec-trical charge above the channel region of a MOST, as a result of which the threshold voltage of the MOST is determined by the stored information.  Writing/erasing of the memory generally requires high voltages to cause charge current to flow through an insulating layer to and from the charge storage region.  In order to avoid para-sitic MOSTs becoming conductive, means are provided by which during operation a small reverse bias is applied to the sources of these parasitic transistors, as a result of which due to the high ? factor the threshold voltage of the parasitic transistors increases considerably.  This does not require additional logic because use can be made of the generator in the reading circuit, which generates a suitable small voltage.
