Abstract: A portable Machining Turntable (PMT) (1) used in combination with a milling, grinding or drilling machine (101) to allow both single and compound angles to be worked. The PMT (1) is comprised of an integral housing (2) enclosing an electric stepping motor (23) that through two pulleys (22), (24) and a timing belt (27) drives a worm drive assembly (17). The worm (21) drives a worm gear (43) that rotates a rotary head (36). The power to operate the motor (23) is supplied and controlled by a conventional numerical control system. However, the PMT (1) includes a mechanical override that allows the rotary head (36) to be manually rotated. To operate the PMT (1) it is mounted to a mill bed by standard clamp blocks inserted into hold-down slots (14) located on the lower walls of the housing (2). The work piece is then attached to the rotary head (36) and the head is rotated to the desired work angle. If compound angles are required the PMT (1) is secured to standard machine vise, attached to the mill bed, and positioned within the vise to provide the first angle. The second angle is then produced by rotating the rotary head in the prescribed manner.

Patent WO-8602117-A1 (WO)
Title: Corner tooth for a bucket
Inventor: KLETT GENE R
IPC: E02F3/40
Filed: 1984-12-18
Abstract: A corner tooth is useful, for example, on construction equipment buckets to protect the sidewalls from abrasive wear which normally results from continued contact with the ground. In order to protect the sidewall, others use elements secured directly to the sidewall or various forms of specialized teeth mounted on the corner. Many of these specialized teeth inhibit the tooth's ability to penetrate the ground. The present corner tooth (10/10") provides the protection for the sidewall (36/38) while still maintaining good strength and penetration. This is due to a single flat member (52) being oriented vertically with respect to the normal working position of the tooth and a single reinforcement rib (54) extending perpendicular to the flat member (52). Furthermore, since the tooth (10/10") is symmetrical about the second plane (50) and the rib (54) is located along the second plane (50) the tooth can be used on either corner. This eliminates the need to manufacture and stock an extra part of a different design. Furthermore, once the part is installed, it remains in the same location for its entire useful life thus eliminating down time to change the tooth from one corner to the other.

Title: Transformerless drive circuit for field-effect transistors
Inventor: NESLER JOHN J
IPC: H03K17/06
Filed: 1985-04-04
Abstract: A transformerless drive circuit for operation of a switch mode regulator includes a turn-on circuit and a turn-off circuit coupled to a control terminal of the switch, respectively, for inducing a state of conduction in the switch and for terminating the state of conduction. The switch is, in the preferred embodiment, a P-channel DMOS field-effect transistor (FET) with a source electrode connected to the positive voltage terminal of a power supply, and with the drain terminal connected to load circuitry of the regulator. The gate electrode serves as the control terminal. The regulator includes a sensor of output voltage and circuitry for providing a pulse-width modulated control signal for designating the average amount of current to be passed by the switch. The turn-on circuit and the turn-off circuit share a common diode which operates alternately for conduction or turn-off. The turn-off circuit includes a bootstrap capacitor for momentarily powering the circuit for saturating a transistor therein, the relatively low saturation voltage being impressed at the control terminal for rapid turn-off. The drawing of current by the turn-on circuit pulls a gate-voltage away from the power line for rapid turn-on.

Title: Method and apparatus for making a reflection hologram to interconnect nonlinear optical elements
Inventor: HINTON HARVARD SCOTT
IPC: G02B5/32
Filed: 1985-12-11
Abstract: Method and apparatus for making a plurality of reflection holograms (101-109) positioned in a two-dimensional array to interconnect optically a plurality (120) of optically nonlinear optical devices (121-129) also positioned in a two-dimensional array. The devices are operated to function as optical logic NOR gates, and the reflection holograms optically interconnect the devices to form any desired optical logic circuit such as a clocked JK sequential logic flip-flop circuit. The reflection holograms are made by affixing the devices and a photosensitive material (500) to the opposite surfaces of a layer of transparent material (505). The transparent material maintains the positions of the devices relative to the photosensitive material both before and after the hologram is made. Spatial light modulator masks (501, 502) are temporarily placed over the outside surfaces of the photosensitive material and the devices to mask all but selected areas of the photosensitive material and designated devices from being illuminated by coherent light beams.

Title: Acceleration responsive transducers
Inventor: JENSEN JORGEN
IPC: G01H11/08
Filed: 1985-12-27
Abstract: An improved vibration-responsive device is provided for monitoring the condition of a selected apparatus. The improved device is adapted to be mounted (25) to the selected apparatus and comprises a vibration-responsive transducer (8, 10) capable of generating an electrical output signal when the transducer is subjected to vibrations or shock, an auxiliary transducer (20) capable of producing mechanical vibrations in response to an input electrical signal (46), and an annular spring (16) mounting said auxiliary transducer in force-transmitting relation to the vibration-responsive transducer. The device is adapted to be connected to (1) a monitoring system (44) for monitoring the electrical output of the vibration-responsive transducer (the ''primary transducer'') and (2) a computer for selectively energizing the auxiliary transducer with an externally generated test signal. When the auxiliary transducer is energized by the test signal, it will cause the associated primary transducer to vibrate, whereupon a change in the signal output of the primary transducer will occur if the latter is operating correctly. If the signal output of the primary transducer does not change when the auxiliary transducer is energized by the test signal, the interrogating party may validly conclude that the primary transducer is malfunctioning. The invention contemplates several ways of arranging the auxiliary transducer in force-transmitting relation to the primary transducer. Preferably the auxiliary transducer is disposed between the primary transducer and its mounting base (2). Alternatively the auxiliary transducer is clamped between the mounting base of the primary transducer and the surface to which the base is mounted. In an alternative embodiment, the primary and auxiliary transducers share common piezoelectric elements.

Title: Traffic advisory-vertical speed and radar display
Inventor: GRALNICK PAUL EDWARD LOUIS
IPC: G01S13/933
Filed: 1988-08-22
Abstract: An electronic display for presenting to an aircraft flight crew the combined information outputs of a vertical speed sensor and a TCAS computer aboard an aircraft. TCAS traffic advisories, i.e. the locations of other aircraft in the vicinity of the protected aircraft, are presented in a first display area of an electric display panel, preferably in PPI format, showing range, relative bearing and relative altitude, if known. Vertical speed of the protected aircraft is indicated in a second display area adjacent the first display area on the same display panel. Whenever the TCAS computer determines that a particular aircraft constitutes a collision threat and that the establishment or maintenance of a specific flight path is necessary to minimize the probability of collision, the TCAS computer issues a resolution advisory which is displayed by identifying the threatening aircraft with a characterizing symbol in the first display area and by indicating symbolically and by other distinctive visual means, such as contrasting colors, in the first and second display areas the specific flight path to be established or maintained.
