Abstract: ABSTRACT               A pneumatic bottle stop for a case packer is presented.  Fundamentally, the bottle stop con-sists of a cylinder associated with each lane of a case packer.  A piston of each cylinder extends into the lane. for making contacting engagement with oncoming bottles or articles.  The bottles compress the piston into the cylinder, expelling air there-from through an adjustable orifice of an associated quick dump valve.  The pistons are extended by the application of exhaust air derived from a head con-trol cylinder when the piston of that cylinder is drawn to position skid bars in the head to receive oncoming bottles.  A bleeder valve is provided such that the cylinders associated with each lane are maintained at atmospheric pressure after extension of the associated pistons.

Abstract: ABSTRACT OF THE DISCLOSURE     An ambient sensing electrochemical device comprising an inert non-silicon substrate; a monolithic semiconductive device formed on a first portion of a first surface of the substrate and integral therewith; a sensor for sensing at least one property of the ambient formed on and integral with a second portion of the first surface of the substrate removed from the first portion; and a connector for connecting the sensing means to the semiconductive device.  By using an inert substrate in place of a substrate such as silicon, ion migration through the substrate and resulting degradation in device performance is minimized.  The device is useful for monitoring the composition of a chemical environment, for example, to regulate chemical or biochemical processors, to determine air or water quality, or to measure parameters of interest in biomedical, agricultural or animal husbandry disciplines.

Abstract: ABSTRACT                  INTERNAL BUBBLE SUPPRESSION      The novel method substantially reduces the pressure pulse  generated  by  an  implosion of a cavity within a body of water by aborting the implosion. The abortion of the implosion  is  produced  by  generating  within  the cavity an  explosion  at  the  instant that this cavity attains its maximum volume.  The method can also be used to  generate  within  a body of water an impulsive acoustic signal by generating a  first  explosion  within the body of water to produce therein a powerful pressure pulse and a cavity  of  very low  pressure, and  then  generating a second explosion within  the  cavity  so  as  to  establish   hydrostatic pressure  inside  the  cavity  while  the  volume of the cavity remains within  a  few  percent  of  its  maximum volume.     The apparatus comprises first (10) and second (10 ) explosive  generators  which  consecutively  create  two explosions within the body of water: a  first  explosion which  produces  within  the  body  of  water a powerful acoustic pulse (PO) and an expanding cavity (1) of  very low  pressure,  and a second explosion which establishes hydrostatic pressure within the  cavity  (1)  while  the volume of the cavity (1) remains within a few percent of its  maximum  volume, thereby substantially reducing the ensuing secondary pressure pulses.

Abstract: ADJUSTABLE AUXILIARY VEHICLE LIGHT                 Abstract of the Disclosure An adjustable signal light which is attachable to the rear window of a vehicle.  The signal light has a bracket with a frame that may be secured to the inside surface of the vehicle rear window by adhesive means, and a pair of spaced side fins which extend from opposed sides of the frame.  A lamp housing is rotatably mounted between the bracket side fins and defines a lamp chamber open generally toward the frame opening at a desired angle thereto.  A lamp is mounted within the chamber and electrical means connect the lamp to the electrical system of the vehicle.  A lens is secured to the housing to enclose the lamp in the lamp housing and refract light from the lamp through the frame opening.  A removeable cover is engaged on the bracket to enclose the lamp housing and secure the bracket side fins in locking engagement with the lamp housing to prevent rotation of the lamp housing during use.  The cover and lamp housing are removeable from the bracket to permit service of the lamp and electrical components without detaching the bracket from the vehicle window.  The lamp housing peripheral wall has an opening in which a metal heat sink is mounted, and a circuit board with logic circuit may be mounted within the housing in proximity to the heat sink. The heat sink conducts heat from the lamp and the logic circuit components within the housing out of the housing. Ventilation openings in the upper and lower portions of the cover permit the flow of air past the housing to remove heat from the signal light.

Abstract: : 14 :     ABSTRACT OF THE DISCLOSURE The domestic communication network has a main control unit which can selectively address sixteen separate stations by sending signals along the common electrical mains wiring.   Each station has a unique four-bit address identity, while each signal sent out by control unit has an address signal (formed of a four-bit address word and a mask code) and a data signal.   The mask code informs the stations of how many bits in the address word are to be ignored.     Each station has a unit to extract, from the address signal, the mask code and input it to subtractors, for modification of the station identity and the received signal to the same number of most-significant bits.   Suitable equivalence at a comparator actuates a switch for activation of a circuit.

Each adjustment motor is arranged between the related roll surface to be moved and its related roll stand.  A regulation device is arranged between a pressure source, the pressure chamber of the adjustment motor and a vessel for the hydraulic medium.  This regulation device is structured for regulating the impingement of the pressure chamber with different pressures up to the maximum pressure of the pressure source and for regulating the outflow of a selected volume of the hydraulic medium out of the pressure chamber, correlated to the desired lowering of each roll surface, during lowering of the roll surface and for maintaining a residual volume of the hydraulic medium.  Consequently, there is provided a defined relative position between the roll surfaces.  With this apparatus there can be thus accomplished the raising, relieving, lowering or holding of the work surfaces of the rolls  in  desired  positions.   The  apparatus  is  also particularly suitable  for very rapidly moving apart the individual rolls, especially the intermediate rolls of the roll stack, and by setting an appropriately reduced pressure in the pressure chamber is capable of taking-up the weights to be relieved, for instance the so-called overhanging or cantilever weights or marginal loads at the individual roll surfaces and to counteract the same.
