Abstract: A vertical spindle numerically controlled machining center includes a stationary bed or base (12) on which a workpiece holding table (18) is slidably mounted for movement along a first axis (16). A vertically extending upright or column (28), having a vertically reciprocal spindlehead (42) slidably mounted thereon, is slidably mounted on the bed (12) for movement along a second axis (26) perpendicular to the first axis (16) so that the spindlehead (42) overlies a portion of the table (18). Within the upright (28) is a recess (78) adjacent to the bed (12). A tool storage magazine (82) is located in the recess (78) and is slidably mounted on the bed (12) for movement through the recess (78) along an axis parallel to the second axis (26). During a tool change cycle, the toolholder then held in the spindle (44) is returned to the tool storage magazine (82) by first moving the spindlehead (42) to the ready position and then moving the tool storage magazine (82) toward the spindlehead (42) to engage the tool then held in the spindle (44). To provide the spindle (44) with a new tool, the spindlehead (42) is first moved upwardly to clear the toolholder shank and then the tool storage magazine (82) is indexed to position a new tool directly beneath the spindle (44) so that the spindle (44) can engage the tool when the spindlehead (42) is moved downwardly to the ready position.

Abstract: An ignition system comprises a ferro-magnetic disc (10) mounted on the distributor shaft (11) and provided with four pairs of protuberances (16, 17), the spacing of the two protuberances of each pair corresponding to maximum and minimum spark advance positions. The protuberances (16, 17) are detected by a first variable reluctance pick-up (19) of fixed position and a second variable reluctance pick-up (18) angularly movable by an engine load sensor (20). The two pick-ups (19, 18) are connected respectively to two signal generators (22, 21) which produce a rectangular waveform (WF) of fixed phase and a rectangular waveform (WV) the phase of which varies in accordance with engine load. The two waveforms have the same frequency. A function timing circuit (23, 30 to 37) responsive to both waveforms calculates engine speed, engine load and crank-shaft position and from these produces a trigger signal for each ignition spark. Further circuitry (40, 42, 43, 50 to 53) responsive to the trigger signals drives the ignition coil (44).

Abstract: A fiber optic recirculating memory is disclosed which utilizes dual couplers (110, 210) to form a splice-free recirculating memory device from a length of single mode optical fiber (112) forming a loop (140) which acts as a delay line and a second length of single mode optical fiber (130) which provides an input end (132) and an output end (134) for the device. A single signal supplied as an input to the device will result in a series of output signals identical to the input signal, although at smaller, decreasing amplitudes; the invention prevents the first output signal from being substantially larger than the rest of the output signals, thus eliminating the need for protective circuitry on the output end (134) or the rejection of the first output signal. In addition to being useful as a recirculating memory device for use in a system where data is generated at a rate faster than it can be accepted by a data processor, the invention may be used as a tap filter to pass a selected fundamental frequency and its harmonics, and to attenuate all other frequencies.

Abstract: An interface circuit (10) for coupling a parallel data device (12) to a serial data channel (14,16) over which Manchester-type codes are transmitted. In the interface circuit, an efficient and reliable Manchester decoder (22), comprising a flip-flop (50), an exclusive-ore gate (52), and at least one delay line (58A or 588) separates the data and clocking signals. The serial data signals are clocked into a serial register (30) under control of the external clocking signals from the channel. A carrier detector (24) enables the serial register only when valid information signals are present. A parallel data register (40) receives in parallel the data from the serial data register. To get in phase the external clocking signals with the internal clock source, an internal clock synchronizing circuit (34, 42) recycles the internal clock source upon the occurrence of a synchronizing character that is transmitted over the serial data channel. In this fashion, the internal operations of the parallel data transfers are in phase, but isolated from the external clocking signals so that in the event that the external clocking signals become corrupted due to noise or simultaneous transmissions of information signals by different devices, the internal parallel transfer operations may continue freely without disruption.
