Abstract: ABSTRACT OF THE DISCLOSURE:            A cutting tool with removable blades, comprising a stack of discs each having at least a cut opened on its periphery,  and  clamping  means  compressing  the  stack  of discs. The angular position of the discs relative to each other  is  such  that,  in working position,  the cuts  form at  least  one  peripheral  longitudinal  housing.  At  least a blade, the cutting edge of which is situated on a diameter longer than the external diameter of the discs is fixed in at least one of the housings by means of a locking ele-ment disposed in the housing parallel to the blade.  The size of the cut  is such that the blade and the locking element are introduced with clearance in the longitudinal housing formed by the cut. The locking element is an elon-gated wedge which bears against the blade when the tool is rotated.  The wedge has means including wedge surfaces that converge in a radially outward direction whereby cen-trifugal force causes the wedge to lock said blade by jam-ming when the tool is rotated.

Abstract: ABSTRACT OF THE DISCLOSURE The current that drives the motor for a slicing blade is continuously monitored to detect when it rises above a thres-hold level. This threshold level is related to the resistance to the rotation of the blade that it presented by a product being sliced. When this current rises above the threshold level, the slicing operation is momentarily interrupted. The threshold level is adjustable in accordance with the number of slices that is desired to be trimmed. While the slicing operation is inter-rupted, the first few irregular slices from the leading edge of the product can be carried away from the location of the slicing blade. Then slicing can resume with the first slice in the first full draft being a full slice.

Abstract: INCINERATOR & CREMATOR          ABSTRACT          The cremator disclosed is of the kind in which reduction  burning  takes  place in  a  coffin chamber,   followed by oxidation   burning  in an  afterburner  chamber.   It is also of  the kind  in which partly cremated embers  can  be moved  to  an ember-reducing location to  make room for another coffin to be admitted to  the coffin chamber.  The disclosure shows the ash removal  port  in  the side of  the  cremator, which allows the afterburner chamber to occupy space   behind  and  underneath   the   coffin chamber; an arrangement which makes for a very compact,  fuel  efficient,  easy-to-construct unit.   The  hearth includes an ash-trough for ember  reduction.   The  hearth  can  be  thin because  it is supported on the  central  wall that  divides  the  ducts of  the  afterburner chamber,  which makes for good heat  transfer, and quick warm-up.

Abstract: PULSE-WIDTH CONTROL OF BONDING BALL FORMATION          Abstract of the Disclosure A method, timing control circuit, and power supply are described for initiating arc discharge between the cover gas delivery shroud and lead wire held in the bonding tool of a lead wire bonding machine for melting and forming a ball at the end of the lead wire.  An arc discharge timing control pulse controls duration of the arc discharge within an empirically determined time window between the shortest and longest durations of arc discharge which result in optimal ball formation of a substantially spherical ball at the end of the lead wire without necking of the lead wire above the formed ball.  The timing control circuit also provides an initial cover gas movement delay before ball formation for displacing oxygen from the shield and the end of the lead wire, and a subsequent cooling delay for solidifying and cooling the formed ball in the cover gas stream prior to ball bonding.  Intially, the lead wire tail length extending below the bonding tool is selected to provide a ball of specified size; the voltage is selected according to tail length to form the mass of tail length metal into a substantially spherical ball; and a neck of desired thickness is selected by adjusting the duration of the arc discharge timing control pulse within the time window.

Abstract: ABSTRACT OF THE DISCLOSURE     A clamping device which has a plurality of elongated clamping members joined to a clamp main frame by a pair of slideable side plates which allow the separate clamping members to be moved axially relative to each other and to the clamp main frame so that the clamping members can be adjusted to com-pensate for irregularities in those workpieces to be clamped that require coaction of two or more clamping members.  The slideable side plates are fixed to the clamp main frame and con-nected to the clamping member by pegs slideable in slots on the clamping member and side plates.  A locking nut and bolt clamp the side plates to the clamping member to fix the portion of the clamping member to the frame once the position of the clamping member is determined.  The side plates can accommodate relative movement of the clamp support member and can be easily removed from or shifted along the support member.  In one embodiment, the pair of side plates are engaged to a coacting pair of horizontal stationary clamp supporting members on the main frame.  To provide for disengagement therefrom, the clamp carrier is raised to enabling relative movement along the supporting members and enabling removal therefrom.

Abstract: MEMBRANE TYPE NON-INTRUSIVE ICE DETECTOR        ABSTRACT OF THE DISCLOSURE An ice detector of the vibrating element type comprises a tube that vibrates along its longitudinal axis, and is driven by an excitation coil at the natural frequency of the tube is sealed by a diaphragm which has a surface exposed to an air stream in which icing is to be sensed.  The exposed diaphragm surface is deflectable during vibration of the tube at a flexible support portion of the diaphragm.  As ice accumulates on the exposed surface of the flexible support the spring rate or flexibility of the flexible support changes, thereby changing the natural frequency of the vibration of the tube section.  The changes in the natural frequency are sensed to determine that ice is accumulating.  The diaphragm is of low mass, and small so that stiffness of small amounts of ice significantly changes the spring constant of the flexible support and the diaphragm is shaped to conform to adjacent aerodynamic surfaces.
