Abstract: DIGITAL CIRCUITRY FOR SPARK TIMING AND  EXHAUST GAS RECIRCULATION CONTROL                        ABSTRACT      A digital signal processing circuit for controlling the spark timing and exhaust gas recirculation (EGR) of an internal combustion engine is disclosed herein.  The circuit first samples the magnitude of the vacuum manifold pressure and produces a complex function analog output signal in response thereto.  The output signal is produced by first converting the vacuum pressure to a digital signal, then using a read only memory to produce a complex function digital output signal and then reconverting the digital output signal to an analog output signal. The pressure analog output signal is then stored in a first holding device.  Subsequently, an analog signal proportional to the period of engine revolution is sampled by the same circuit.          However, the circuit now develops a digital output signal which is a function of the inverse of this analog input signal and this inverse digital output signal is effectively multiplied by the held pressure analog signal to produce an EGR analog control voltage which is stored in a second holding device.  Subsequently, an analog output signal which is a different inverse function of the engine period is developed and stored in the first holding device and then the EGR analog output signal is processed by the circuit and effectively multiplied by the analog signal now being held in the first holding device to produce a spark timing control analog output signal which is stored in a third holding device.  The EGR control signal in the second holding device controls how much exhaust gas will be re-injected into the cylinders of the internal combustion engine and the spark timing control signal in the second holding device adjusts the timing of the sparks generated for the cylinders of the internal combustion engine.

Title: Apparatus for reflecting and controlling radiant energy
Inventor: GULLIKSEN JOHN E
IPC: F21V9/40
Filed: 1978-06-14
Granted: 1982-03-16
Abstract: ABSTRACT   A source of radiant energy is combined with spaced apart reflecting surfaces which are sections of paraboloids of revolution and which have a common focal point but differing focal lengths.  Radiant energy is reflected in substantially parallel rays and passed through radiation transmitting means which include radiation control  zones.  The reflecting surfaces and the radiation transmitting means are mounted for rotary displacement of one relative to the other to vary the distribution pattern, intensity, color, and other characteristics of the reflected radiant energy in a unique manner. Radiation output from the source of radiant energy may be instantly tailored to a task at hand such as may arise, for example in theatrical lighting, mine lighting, police and surveillance work, military operations, fire fighting, sports activity, illumination of recreational areas and the like. By means of the unique construction and arrangement of the reflecting and transmitting components, it becomes possible to achieve a relatively high degree of efficiency and operating life in a range of luminaire sizes which can be manufactured on a commercially feasible basis.

Abstract: ABSTRACT OF THE DISCLOSURE     A motion transmitting remote control assembly which prevents connection of the outer casing members of adjoining mechanical push-pull control sections unless the inner trans-lating core members are connected.  The assembly includes at least two inner translating core members for transmission of motion and being detachably connected for allowing connected and disconnected positions.  At least two outer casing members slid-ably receive the inner translating core members and are detachably attached by a coupling nut for allowing attached and unattached positions.  A spring-loaded finger member having a flange portion is pivotally housed in a longitudinal cavity in one of the core members.  The flange portion protrudes to be engageable with an abutment surface defined by an annular groove axially disposed within one of the outer casing members to provide an inoperable position of the assembly.  The portion of the outer casing member surrounding the annular groove encloses the finger member in order to limit access to the finger member.  A head member is connected to the other core member by an extension member.          The first-mentioned core member has a slot which terminates in a radial bore adjacent the longitudinal cavity for receiving the extension member and the head member.  The finger member has a reactive surface which cooperates with an interaction surface on the head member for moving the finger member to a retracted position when the inner translating core members are connected in order to provide an operable position of the assembly whereby the outer casing members may be connected.  Additionally, the second-mentioned inner translating core member engages a shoulder surface defined by its associated outer casing member to limit axial movement of the second core member.

Abstract: ABSTRACT          The present invention relates to an apparatus for as-sembling contacts into the contact mounting pockets of a ribbon connector.  Handling and insertion of the contacts into the connec-tor Pockets is difficult to perform with prior art automated equipment because of jamming problems or damage to the fragile contacts during the loading operation.  The present invention overcomes these deficiencies of the prior art by providing an apparatus which includes means for assembling the contacts in proper orientation for insertion into the pockets, means for transferring the contacts for the contact assembly means into an initial mounting position within the pockets, and means for seat-ing and retaining the contacts in a final mounting position within the pockets.  The apparatus provides structure to positively con-trol the movement of the contacts throughout the loading operation to thereby minimize jamming or damage to the fragile contacts.
