Abstract: ABSTRACT An analog to digital conversion system using an analog to digital converter (ADC) and a digital to analog converter (DAC) is described.  A fre-quency dependent variable response network, with or without associated gain, is provided in combination with the ADC and DAC.  The frequency dependent variable response network changes the shape of its response characteristic in response to a control signal.  The invention may be viewed as an adaptive pre- and de-emphasis in combination with the ADC and DAC, whereby the most audible noise is reduced by the response shaping network whenever input signal amplitudes do not lead to system overload, but when overload would occur, the networks adapt to avoid boosting predominant spectral components while retaining noise reduction where noise might be audible in the presence of those spectral com-ponents.  Such a system permits much more boost and cut in the presence of predominant signals at frequencies where noise is not a problem, and can therefore render noise modulation inaudible.

Abstract: ABSTRACT     This invention is for a multi-cultured yogurt or dairy spread such as cottage cheese and the process for making them.  Yogurt is normally produced by inoculating milk with L. bulgaricus and S. thermophilus then letting fermentation breakdown the milk lactose.  The accomplishment of this invention is the recognition that more lactose can be broken down by adding a second fermentation step to the usual yogurt making process. The result is that one maximizes the breakdown of milk lactose into glucose and galactose while enhancing the amount of enzyme lactase in the finished product.  B. bifidum or L. acidophilus are disclosed as the preferred mircroorganisms used in the second fermentation steps.           The invention further relates to a method of pro-ducing multi-cultured dairy products containing Bifidobacterium bifidum using a fermented dairy product, such as yogurt or buttermilk, multi-cultured with B. bifidum.  The products made according to the method can be further processed into a spread, cottage cheese, or frozen dessert.  The invention also relates to the starter cultures used in the method and the dairy products thus produced.

Abstract: ABSTRACT OF THE DISCLOSURE    Resistance to cathodic or galvanic disbondment of plastic-metal  laminates  is  obtained  by  incorporating  in the metal bonding plastic material used in forming the laminate an amount of  conductive carbon black effective to minimize or prevent disruption of the bond by galvanic action which otherwise would take place in the absence of the conductive carbon black.  The conductive carbon black is used in a relatively high concentration, for example, between about 20 and about 40 percent, with the balance of the composition being made up of a polymeric material containing an amount effective to promote bonding between the metal and the polymeric material of an ionomeric co-polymer containing about 25 to about 98.5 percent ethylenic units and between about 1.5 to about 30 percent carboxylic acid units, the major proportion of which is in the free acid form.   Advantageously, two-thirds or more of the carboxylic units are in the free form and the remainder, if any, are neutralized by zinc.

Abstract: ABSTRACT OF THE INVENTION A scannable asynchronous/synchronous CMOS latch circuit that includes a first, second, and third latch element, an asynchronous latch section, and a clock control section.  When operated as a synchronous latch, the first latch element operates as the "master" portion and the second latch element acts as the "slave" portion of a master/slave latch.  The clock control circuit enables the  clock  signals  to  control  the  synchronous operation of the master/slave latch.  When operated as an asynchronous latch, the clock control circuit disables the clock.  The output of the asynchronous latch section is connected to the input of the first latch element.  An asynchronous signal appearing on one of the inputs of the asynchronous latch section passes  through the  first and  second  latch elements  and  is  applied  to  another  input  of  the  asynchronous  latch section,  causing  it  to  be  latched,  or  held.   Separate  outputs  are provided  for the asynchronous latch and  the  synchronous  latch.   When scanning occurs,  the second and third  latch elements act  as  a  shift register stage.  The second latch element acts as the master while the third latch element acts and the slave of a master/slave latch.   The contents of the asynchronous latch can be latched in the slave section of the synchronous latch for scanning.   Shift-in data is coupled  to the master, then transferred to the slave, where it appears on the shift-out output, by appropriate clock signals.

Abstract: ABSTRACT OF THE DISCLOSURE         An electrically powered hand tool, such as a staple gun, can employ an electrical driver, such as a solenoid, which is actuated by a trigger circuit in response to depres-sion of a trigger on the handle of the device.  The trigger circuit can include a circuit board dimensioned to fit into the handle of the staple gun, and having AC input leads.  A circuit formed of conventional electronic components delivers a burst of power to output leads which are in turn connected to a driver solenoid. This circuit is actuated to deliver the power burst by opening of a switch formed of two switch members: one switch member has a first flexible resilient conductive leaf formed, e.g., of an alloy of copper, extending beyond an edge of the board; the other member has a flexible resilient leaf with a bent-in pointed end contacting a side of the first blade.  These blades are biased against each other to form a normally-closed switch.  When the first blade is moved in one direction, the switch opens.  When the first blade returns in the other direction to close the switch, the pointed end of the other resilient leaf or blade scratches off corrosion at the contact area of the two members.  This permits low current (1 ma) to be used as a control current through the switch.
