Abstract: ABSTRACT OF THE DISCLOSURE           A  signal  generator  for high  level  low  noise signals is disclosed.  The preferred embodiment of the invention utilizes the output signal of a low noise crystal oscillator as a fundamental reference signal.  The funda-mental reference signal is multiplied to generate a series of coherent reference signals.  Additionally,  one of the coherent reference signals is coupled as an input signal to  a divide circuit  to generate  at the output of the divide  circuit  a  plurality  of  coherent  low frequency reference signals.  The coherent reference signals and the low frequency coherent reference signals are utilized by a synthesizer to generate a plurality of coherent signals having a frequency determined by the  synthesizer.  The output signal of the synthesizer is combined with one or more of the reference signals to generate the microwave output signal which is stepped from a minimum to a maximum value in equal increments.

Abstract: ABSTRACT OF THE DISCLOSURE         An air induction system for an automotive air-conditioner has an air switching housing connected to the suction opening of a blower casing.  The housing is provided with a fresh outdoor air induction opening formed in the top wall opposing the suction opening, and a recirculated indoor air induction opening formed in a side wall adjacent to the top wall.  An air-switching door is provided for selectively opening and closing the outdoor air induction opening and the indoor air opening.  The air-switching door is foldable substantially at its mid portion so that, when the door closes the indoor air induction opening, it is folded to provide a small effective area, while, when it closes the outdoor air induction opening, it is extended to provide a large effective area.  The system further has auxiliary indoor air induction openings formed in other side walls and an accordion-type shutter for selectively closing and opening the auxiliary indoor air induction opening.  The air switching door and the accordion-type shutter are operatively connected such that, when the door opens the outdoor air induction opening and closes the indoor air opening, the shutter closes the auxiliary indoor air induction openings.

Abstract: A B S T R A C T     A high speed feeder for carton blanks being fed into a cartoner includes both mechanical and fluid flow environments for precisely delivering carton blanks.  A preferably inclined conveyor has an upper run which receives generally vertically oriented blanks stacked on their edges.          Blanks are fed one at a time from the stack at the down-stream end of the upper run.  A pressure roller is pro-vided adjacent and upstream of the feed zone so as to over-lie  the upper run and to engage with the upper edges of the blanks.  The pressure roller holds back most of the upstream blanks while permitting only a few blanks to pass by.  This structure relieves the pressure from the weight of the up-stream blanks on the few downstream blanks.

Abstract: ABSTRACT           In a method of liquefying coal at elevated pressure  and  temperature  in  a  reaction  zone,  the reaction  product  leaving  the  reaction  zone  is  fed to a  coking  zone,  and the gases and vapours formed therein,  mainly distillate  oil  vapours,  are  cooled, preferably by direct heat exchange with a fresh coal slurry.    The  gases  and vapours  which    are    not cooled  by  this  heat  exchange  are  remoded  from the installation as end products.  The method of operation transfers the oil production partly from the reaction zone  to the  coking zone,  so that the reaction zone may  be  operated  at  a  low  pressure.    In addition, the direct heat exchange between the vapours produced and the  fresh  coal  slurry enables  a  large part of the  exothermal  heat  produced  during  the  liquefying reaction to be returned to the process.

Abstract: Abstract Method for the continuous production of shaped bodies, in particular boards, from a mixture of gypsum and fibrous material and apparatus for carrying out the method The invention relates to a method for the continuous production of shaped bodies from gypsum and fibrous material in which firstly a proportioned amount of gypsum and fibrous material are intimately mixed together, the mass of the dry gypsum-fibrous material mixture then being measured.  In a second mixing operation underproportioned water addition the mixture is moistened and is then spread to form shaped bodies whose surfaces are subsequently moistened; the shaped body is then compacted.  To obtain higher strengths it is further provided to divide the mass flow into separate sub-mass flows and to spread the shaped body in several layers, each sub-mass flow forming a layer of the shaped body.  Each deposited layer is subsequently moistened with water, and the total amount of water added to a shaped body may be up to 25% above the stoichiometric water amount for setting the gypsum-fibrous material mixture.

Abstract: Abstract of the Disclosure A reduced-size thermal overload relay having a housing that includes three narrow compartments in which are mounted three connector brackets supporting three flat bimetal members.  Three narrow casette heaters are mounted at the upper part of the housing and held in by a snap-in hold-down device that engages pairs of hooks at the lower portions of the heaters.  A pushbutton on the hold-down device extends through a hole in the front wall of the housing for manual depression to release the heaters for removal.  Each bracket is H-shaped having legs for mount-ing it in a housing compartment and arms connected by a platform to which the upper terminal clip is clamped with a screw, the small angles of this platform and terminal clip automatically drawing the flat heater element into desired spacing with the bimetal member.  The current flow down the arms prevents loss of heat through the terminal lead.  A switch mounted at the side of the housing is tripped by a joint or differential operating mechanism mounted below the three compartments and actuated by the three deflecting bimetal members.
