Abstract: METHOD AND CONSTRUCTION FOR SPIRAL WIRE BINDING OF PADS               ABSTRACT OF THE DISCLOSURE             A machine for feeding and simultaneously binding pairs of relatively small spiral wire bound pads. Groups of sheets of twice the final desired size are fed serially to a station where they are split and separated. Pairs of the split pads are then fed through a conventional coil binding machine having stations where they are successively aligned and receive a single spiral binder while in side-by-side and slightly spaced relationship. At the next station cutter means are provided for simultaneously trimming and inwardly bending both the outer and the inner ends of the binders of both pads. The two trim-cutting and bending assemblies for the outer ends are of conventional construction having a fixed cutter member and a movable blade operated by a cam with a diagonal slot. The trim-cutting and bending assembly for the inner ends however is of novel construction, comprising two fixed cutter members carried by a single arm and spring-urged movable cutter blades actuated by a V-shaped cam on another arm.

Abstract: PHN.8954 ABSTRACT:         Delta modulation decoder comprising an integrating network provided with a first integrating capacitor which is on the one hand connected to an input terminal of the integrating network and on the other hand to ground po-tential through a second integrating capacitor. The 1-pulses and O-pulses of the delta modulation signal, ap-plied to the decoder, are applied to a current source cir-cuit generating a positive charging quantum in response to each 1-pulse and a negative charging quantum in res-ponse to each O-pulse. Said charging quanta are applied to the input terminal of the integrating network through a correction network. This correction network is con-trolled by the voltage VC3 across the second integrating capacitor, so that, if VC3 is positive, the positive charging quanta are reduced and/or the negative charging quanta increased and that, if VC3 is negative, the posi-tive charging quanta are increased and/or the negative charging quanta reduced.

Abstract: ABSTRACT  OF  THE  DISCLOSURE     In a centrifugal fan or the like including an impeller housed in a casing, recirculation means are provided to recycle a portion of the gas discharge back to the blades of the impeller.   Specifically these means comprise a radial passage between an impeller shroud and a wall of the casing, and aperture means in the shroud.   15% to approximately 30% of the gas discharge may be recycled.     This arrangement has the advantage of increasing the fan pressure at low discharge rates in comparison with previous fans with no gas recirculation, and this is advantageous in some fan installations where operation is at reduced rates for considerable periods.

The system also includes a random access memory, a keyboard, a video terminal, and a port device in the form of a tape recorder/player.  A master clock initiates timing used throughout the system.  A multi-line data bus interconnects the CPU and the different memories of the system including the keyboard and the video RAM.  Bi-directional communication is possible on the data bus.  The addressing of these different memories is by way of an address bus from the CPU, which is a uni-directional bus.  Data to be operated upon is basically stored in the random access memory.  The keyboard is used for inputting data to the CPU and the video terminal is used for displaying data.  Features of the present invention include a special reset scheme for the CPU, a multiplexing scheme for addressing the RAM, a teaching for simply altering the control to provide capabilities of different capacity memories, alternate display of characters to provide, for example, either a 32-character line or a 64-character line, an improved keyboard selection scheme, and improved video processing means.     1.

The electronic control  unit  has an open loop calibration for regulating air/fuel ratio that is corrected with a  closed  loop  correction  signal  developed  by  an integral controller.  The open loop calibration is a speed-density based schedule which is combined with corrections for  special  conditions  to  account  for  the  operating parameters of the engine at any instant.  Included in these special condition corrections are provision for start and warm-up features.  The start feature includes an enrichment pulse generator whose pulses have a duration dependent upon the  engine  operating  temperature  and  speed  which  are inhibited while the engine is above a predetermined RPM. The  warm-up  feature  includes  a  time  and  temperature dependent enrichment which is linearly multiplied by an engine load factor.  The warm-up feature further includes a time  dependent  holding  level  or  delay  from  which  the enrichment factor value decays during warm up and a feature to  defeat  this  holding level  above  a  certain  engine operating temperature.
