Abstract: Abstract of the Disclosure Shoes having an upper formed with a plurality of dimples with an air hole therein are proposed.  Hot dieing to form dimples hardens the leather at the dimples, increasing the durability of the shoes.  Thus, the shoes are highly durable even though they are provided with air holes in the upper.

Abstract: MULTIPROCESSOR MECHANISM FOR  HANDLING CHANNEL INTERRUPTS                   Abstract The disclosure relates to multiprocessor handling of plural queues of pending I/O interrupt requests (I/O IRs) in a main storage (MS) shared by plural central processors (CPs).  An input/output processor (IOP) inserts I/O IR entries onto the queues in accordance with the type of interrupt.  The entries in the queues are only removed by the CPs, after their selection by a system controller (SC) for execution of an interruption handling program. An I/O interrupt pending register in I/O interrupt con-troller circuits in the SC is used in selecting CPs to handle the I/O IRs on the queues.  The bit positions in the pending register are respectively assigned to the I/O IR queues in MS, and the order of the bit positions determines the priority among the queues for CP handling. An I/O IR command from the IOP to the SC sets a correspond-ing queue bit position in the pending register and con-trols the addition of an entry on the corresponding queue in MS.  If a bit is set to one, the corresponding queue is non-empty;  if set to zero, the queue is empty.  A broadcast bus connects the outputs of the bit positions of the pending register to each of the CPs.  In each CP, acceptance determining circuits connect to the broad-cast bus and accept the highest-priority-unmask non-empty-state bit position being broadcast.  From this, the CP sends the SC an accepted queue identifier signal and an accept signal when the CP is in an interruptable state.  The CP also sends to the SC a wait state signal if the CP is then in wait state.  Selection determining circuits in the SC receive the accept, wait (if any), and queue identifier signals from all accepting CPs and select one accepting CP per accepted queu at any one time.  The selection circuits can perform the selection of plural CPs in parallel, and send a select signal to each selected CP.  An inhibit register in the interrupt controller in the SC inhibits selected bits on the broad-cast bus to all CPs except the selected CP for the selected queue identifier.  The inhibit on any bit is removed when the selected CP ends it acceptance of the corresponding queue, so that any CP can select the next entry on the corresponding queue.  When any selected CP finds it has emptied a queue, it activates a reset line to the SC which resets the corresponding bit in the pending register to indicate the empty state.

Abstract: DETECTION OF TONES IN SAMPLED SIGNALS            Abstract of the Disclosure A tone detector in the form of a digital correlator is disclosed in which PCM signal samples are delayed in a RAM for the correlation period.  Using PROMs, the products of the current and delayed samples with samples of a sine signal at the frequency to be detected are produced, and their difference is cumulatively summed to produce a first accumulated signal.  A second accumulated signal is similarly produced using samples of a cosine signal at the frequency to be detected, and an output signal indicating the presence or absence of the tone is produced from the sum of the squares of the two accumulated signals.  The use of memories enables the detector to be readily multiplexed for detection of a plurality of tones on each of a plurality of channels.

Abstract: ABSTRACT OF THE DISCLOSURE     A water heating column furnace for producing non-corro-sive, drinking-water-quality heated water comprising a body or shell having at least an upper,  heat exchange and stripping compartment and integrally formed and in-line therewith a lower compartment.  A grating separates the integrated two compart-ments and a plurality of heat absorbing and transfer bodies, such  as  for example,  Paul rings,  are positioned within the upper compartment on top of the grating. A greater amount and depth  of heat absorbing bodies  are  provided than would be needed merely for heating in order to also strip the water of substantially all  its free oxygen to eliminate the corrosive effects of CO2 presence.  Cold water is introduced into the furnace by a spray positioned over the heat absorbing bodies with the water running into the lower compartment as it is heated and oxygen-stripped by heating means. The heating means operates at a relatively low temperature free of intense hot spots to avoid NOx formations and its corrosive effects, with the heating means positioned within the lower compartment being in a first direct contact type (Figures 1 - 6) an open, exposed flame with direct flame/water contact and in a second, heat reclaiming  type  (Figures  7  -  8)  hot  exhaust  gases  from  a separate source.  In the first type the furnace has water flow directing means positioned within the furnace shell to direct the downward flow of water to a predetermined area in the lower compartment in order to prevent hot spots from forming on the shell of the furnace in the area of the lower compartment. An exhaust  stack  is provided  above  the upper  compartment  for removing the  exhaust  gas from the furnace with the exhaust stack being formed,  in a generally U-shape configuration. The U-shape configuration acts to prevent back flow of air into the furnace whenever the furnace blowers are shut-off.

Abstract: ABSTRACT OF THE DISCLOSURE     A compact refraction instrument for use in both the objective and subjective examination of human eyes.  The instrument incorporates an alignment mode, a retinoscopy mode, a distance mode and near mode.  For carrying out the functions associated with these modes, the instrument includes a Brewster stereoscope and a system for supporting a plurality of binocular/ monocular vision testing slides.  Positioned along the pair of optical paths between the Brewster stereoscope and the slide supporting system are:  a first mask/septum system; a mode change system; a second mask/septum system; and a horizontal/ vertical target mask system.  The instrument also includes a refractor system and apparatus for suspending the refractor system in the optical paths before the Brewster stereoscope.          The slide supporting system includes two rotatable concentric drums.  The mode change system includes a first mirror for folding the optical paths when the instrument is used for subjective testing at a distance and near vision testing.          Alternately, for retinoscopic examination, the paths are folded by a pair of mirrors having an opening therebetween.  The Brewster stereoscope and both septums are rotatable so that they can be inserted into or removed from the optical paths as required by the various modes of operation of the instrument.
