Abstract: ABSTRACT OF THE DISCLOSURE    The present invention relates to the cutting, chipping and chopping of wood and, more particularly, to a machine using a knife-like blade for cutting and chipping wood into relatively large pieces in a direction transverse, or at least approximately transverse, to the orientation and direction of the grain.  In accordance with the invention, the blade is oriented with regard to the angle of cutting to run between 70 and 30 degrees to the direction of fiber and grain.  This oblique mode of cutting permits a lowering of the force requirement for advancing the blade by about two thirds of the force requirement inherent in vertical cutting devices.  A cut carried out with a relatively oblique angle is preferably used for cutting wood having many knots, while a shallower angle of cutting will be used for hardwood grains.

Abstract: ABSTRACT     A severable wall construction for a tray forming package or carton,  One or more circumferential zones is each defined by overlapping wall portions of the package or carton, each zone being Z-shaped in transverse cross-section.          A tear strip (filament tape) is positioned along each zone, between the middle and one leg of the Z.  The tear strip is pulled to sever the Z at the junction of the middle and one leg and thereby separate the package or carton into two portions.  The remaining middle and other leg of the Z forms an edge hem for one of the two separated package or container portions.  The hem edge is thus defined by a smooth rim.  In one application of the invention, a paper towel roll package is provided with two Z-shaped zones around its circumference.          After ripping both Z zones, that portion of the package originally between them is discarded, and two trays for display  the paper towel rolls are defined.   Kraft paper or paperboard forms the package or container.  The invention may also be applied to multiple package carriers, i.e., carriers for cans,  for easy container opening and access.    The invention also may be applied to a folding carton of rectangular form or a round paperboard can, with the Z fold and tear strip providing a reclosable lid.

Abstract: Abstract of the Disclosure A barbecue grill makes it possible to effect quick and easy extinguishing of any flames that could develop as drops of fat fell into the heating chamber of that grill, by having a grid which normally holds meat in position over that heating chamber but which can be shifted horizontally to move that meat away from that heating chamber, and thereby keep further drops of fat from falling into that heating chamber.  When the flames subside, as they will quickly do, that grid can be shifted to shift the meat back into position over the heating chamber to permit further cooking of that meat.  Also, the barbecue grill enables a person to use his or her hands in placing all kinds of meat on the grid by permitting that grid to be shifted horizontally away from the heating chamber whenever any meat is to be placed on it.  Further, the grill enables a user to shift the grid, and the meat thereon, away from the heating chamber whenever that user wishes to test, turn or remove that meat.  In addition, the meat-supporting grid can be disposed wholly in register with the heating chamber, wholly out of register with that heating chamber, or in any intermediate position to enable all of the meat to receive full heat from that heating chamber, to enable none of that meat to receive heat from that heating chamber, or to enable just some of that meat to receive heat from that heating chamber.  As a result, a user of the barbecue grill can, during a given barbecuing session, cook some meat so it is rare, cook other meat so it is medium, and cook still other meat so it is well-done.

Abstract: ABSTRACT             A frequency doubler for receiving an input clock signal and generating an output signal at twice the input signal frequency and having fifty percent duty cycle.  The input signal is received by a tapped delay line and transmitted from a predetermined tap thereof to a first input of an EXCLUSIVE OR gate.  The second input of the EXCLUSIVE OR gate receives the undelayed input clock signal and generates the output clock signal in response to performing an EXCLUSIVE OR operation on the delayed and undelayed signals.  The duty cycle of the output signal is monitored via a comparator in combination with logic circuitry.  The output of the comparator is connected to the up/down input of a digital counter which is clocked once for each cycle of the input signal, and generates a digital count value in response thereto.  In the event that the monitored duty cycle is less than fifty percent, the comparator generates an up count signal for incrementing the digital counter.  In the event that the duty cycle is greater than fifty percent, the comparator generates a down count signal for decrementing the counter.  The counter output is connected to a decoder circuit for decoding the digital count value and generating a signal to enable one of the taps of the delay line, thereby compensating for drift in the components comprising the delay line, and maintaining the output signal at fifty percent duty cycle.

Abstract: ABSTRACT A flow controller is provided that detects intervals between successive drops and responds to detection of intervals which are too long by shutting down operation of the administration set if the abnormal flow causing the long interval cannot be corrected.  In response to detection of abnormal flow which is not clearly a high flow condition and/or an empty container, the flow controller sequentially opens, closes, re-opens and again closes the clamp of the controller in an attempt to restore normal flow.  If normal flow is restarted before the sequence is completed, the controller returns to normal control of the fluid flow.  Otherwise, completion of the sequence results in a shutdown of the system and activation of an alarm.  In keeping with the invention, indicia are provided in connection with the drop chambers of the administration sets which are sensed by sensing means mounted to the drop detector of the flow-controller in order to indicate to the controller the size of the orifice in the drop chamber.  In addition, a plurality of drop sensors are provided which cooperate to provide a reliable drop signal for angles approaching 30 degrees from vertical.   39-125/cad
