Abstract: ABSTRACT    A portable horizontal drill press for drilling holes in the surfaces of highway vehicles and construction type equipment including a T-shaped base support beam which is mounted on swivel type wheels with low clearance provided to minimize tipping.  A drill support column having a slidable mounting platform for an industrial type drill motor is mounted at one end of the beam support structure.  The drill motor platform includes a hand wheel and lead screw combination which is used for feeding the drill motor into the work.  The height of the drill motor platform can be adjusted either by a rack and pinion gear provided on a one-piece solid column or the column can be provided in several telescoping sections which can also combine a rack and pinion gear for the upper section of the column.  A similar height elevating and positioning arrangement can be provided for a center support column provided at the opposite end of the base support beam.  The center support column can be longitudinally moved with respect to the drill platform along the elongated support beam for adjusting the position of the drill center column in relation to the drill motor.  A drill center rod is provided on the center support column and adjusted to contact that opposite side of the object so as to back-up the drill during the drilling process.  In one embodiment the drill support column has a pivoting socket arrangement whereby the column can be laid down parallel to the support beam to allow the center column to be moved under an object having low clearance and then erected for positioning the drill center opposite the location of the area to be drilled.

Title: Cathode ray tube with dynode having restricted entry  angle
Inventor: WOODHEAD ALFRED W
IPC: H01J31/12
Filed: 1984-07-05
Granted: 1987-04-28
Abstract: ABSTRACT:          In order to reduce contrast degradation in an electrostatically scanned flat cathode ray tube (10) having a channel plate electron multiplier (44), due to back-scattered electrons (45) entering channels remote from their origin, steps are taken to restrict the acceptance angle of the channel plate electron multiplier.  In one arrangement means are provided on the input surface to restrict the angle of entry to a range normally associated with the addressing electron beam (arrow A).  In another arrangement (Figures 9A and 9B or Figure 10) the ready emission of secondary electrons is restricted to a pre-determined arcuate portion of the input of each channel of the electron multiplier.  In either arrangement stray electrons (arrows B and C) are unable to impinge upon the secondary emitting material (48) or surface in the channels and in consequence produce many fewer back-scattered elec-trons.  Optionally a material (50) having a low back-scatter coefficient and a microscopically rough surface texture may be applied to the exposed surfaces, apart from the apertures, of the input side of the electron multi-plier (44).

Granted: 1987-06-23
Abstract: ABSTRACT A technique for high quality low bit rate speech coding is described. The technique involves developing a new pulse location and amplitude sequen-tially based on the pulse location and amplitude previously obtained concerning a speech signal on a frame basis.  As a first step a pulse close to the location of the new pulse based on the pulses previously obtained is selected.  Next, the new pulse is developed based on the selected pulse.  At least the new pulse is then coded.  The invention greatly reduces the amount of calculation required compared with prior techniques.

Abstract: ABSTRACT      A process is disclosed for making a hollow fiber mass transfer device.  A bundle (12)   of hollow fiber (34)  is  formed by winding  a  length of hollow fiber around a core (38) from an arm (20) that is in a plane at an acute angle with respect to the longitudinal axis of the core and is between opposite ends of the core. Relative rotation is provided between the longitudinal axis of the core and the position of the winding arm. During winding of the hollow fiber around the core, there is an increase in the ratio of  (a) the angular velocity of the wind and  (b)  the relative rotational velocity between the longitudinal axis of the core and the position of the winding arm.   In this manner, the void fraction of radially-outward annuli of the wound bundle is less than the void fraction would be if the ratio remained constant.

Abstract: CIRCUIT APPARATUS AND METHOD FOR ELECTROTHERMAL         TREATMENT OF CANCER EYE     Abstract of the Disclosure Circuitry for use in a hand-held electronic probe for passing high frequency current through malignant eye tissue of livestock or other tissue such as warts includes a thermistor in a probe tip that contacts the tissue, producing a voltage that controls a voltage controlled oscillator which drives an audio transducer.  If, during treatment, the probe tip is held against the malignant tissue with sufficient force, the pitch of a sound emitted by the audio transducer steadily increases, indicating to the user that proper pressure is being maintained to ensure heating of the tissue to the desired treatment temperature.  The circuitry then causes the transducer to emit periodic beeping signals which the user can count to ensure that the tissue is maintained in a desired elevated temperature range for a desired amount of time.  Circuitry responsive to the temperature sensor varies the duty cycle of the high frequency current applied to the tissue to maintain the elevated temperature thereof within a predetermined range.  Initially, the high frequency current is applied at a substantially reduced duty cycle to prevent excessive temperature lag between the tissue and the probe tip to prevent initial temperature overshoot of the tissue before the thermistor and circuitry can respond to reduce the duty cycle.
