Title: High velocity pneumatic device
Inventor: ARTZBERGER THOMAS G
IPC: E02F3/92
Filed: 1991-06-18
Abstract: A high velocity pneumatic device for excavating or dislodging soil includes a housing (1) having a passage (2) that connects a source of air under pressure, such as a compressor, to an elongated discharge tube (5). A valve mechanism (6) is disposed in the passage (2) and controls the flow of air through the tube. Mounted in the distal end of the tube (5) is a nozzle (44) having an inwardly converging upstream end and an outwardly diverging downstream end which increases the velocity of the air being discharged through the tube (5). A manually operable trigger (33) is directly connected to the valve mechanism (6) and actuates the valve to discharge air through the tube (5). The nozzle (44) is formed of a non-sparking metal, such as brass, while the tube (5) is composed of an electrically non-conductive material, such as glass reinforced resin. <IMAGE>

Title: Biological signal monitor and transmitter
Inventor: KINOSHITA SATOSHI
IPC: A61B5/024
Filed: 1992-09-08
Abstract: Biological signals detected by detecting units (1) on a plurality of persons to be monitored are first transmitted to wristwatches (3). The biological signals and ID code data are then transmitted in the form of radio signals to a receiver (6) which sends them to a monitor (8). The monitor (8) displays the biological signals in a one-to-one correspondence with the ID code data. Upon detecting an abnormality, the monitor (8) generates an alarm sound. The corresponding person may stop any erroneous alarm sound by manipulating a switch. If it is not a false alarm, the person's wristwatch (3) transmits a contact designation signal and ID code data to the receiver (6) which then activates an auto-dialing unit to inform the third person of the emergency. <IMAGE>

Patent GB-926763-A (GB)
Abstract: 926,763. Measuring rotor unbalance electrically. W. & T. AVERY Ltd. April 19, 1960 [April 22, 1959], No. 13557/60. Class 40 (1). Apparatus for determining the unbalance of a rotor comprises means for applying a pulsating force to the body along its axis and noting the unbalance forces or movements thereby produced. As shown (Fig. 1), a test body 1 is located on a holder 2, with its axis coincidental with that of the support rod 3. Mechanical oscillations are imparted to the test body 1 along its axis by an oscillator generator 4 attached to the rod 3, and unbalance in the body 1 produces oscillations which are sensed by perpendicular pick-ups 6, 7. The unbalance signals are taken to the moving coils of wattmeters 8, 9 whose field windings are energized by a reference generator 10 driven synchronously with oscillator generator 4, whereby the readings on the wattmeters enable the magnitude and angular position of the unbalance to be determined. In another embodiment (Fig. 2), the support rod 23 is made rigid, with resistance strain gauges a-d mounted symmetrically on it to determine the stresses produced by the unbalance in the body 1.

IPC: B01D29/01
Filed: 1993-05-20
Abstract: A filter bag comprises two impervious plastic sheets (2, 3) sealed to each other along three sides to form a pocket, and a filtering sheet (4) which is fixed to at least one of the two sheets (2, 3) so as to divide the interior of the pocket into at least two volumes. The bag is used in the preparation of a filtrate from a solid, fibrous, non-homogenous or insoluble sample in order to carry out a microbiological analysis. In Fig. 1 the sheets 2, 3, 4 are of equal area and sealed together along three edges. In Fig. 2 the filter sheet 4 is smaller and is sealed to only one of sheets 2, 3 along three edges of sheet 4. In Fig. 3 the bag of Fig. 1 is further divided by vertical seams connecting the filter sheet to each plastic sheet alternately, creating a series of chambers through which liquid flows in series being thereby filtered several times. The bag is made by unwinding sections of the sheets from respective rolls and heat sealing them together, while making transverse perforations which allow resulting bags to be separated as required. <IMAGE>

Title: Rotational speed sensing device
Inventor: SHIRAI KATSUYOSHI
IPC: G01P3/488
Filed: 1996-03-22
Abstract: In a rotational speed sensing device e.g. for sensing wheel speed of a vehicle and of the type which includes a pulser ring 11 attached to a rotary part 10 and having a plurality of circumferentially spaced wall portions 11b, and a fixed structure including a permanent magnet M and a coil 22, the fixed structure also includes a first magnetic member 20 and a second magnetic member 21 which have spaced projections 20b, 21b to interact with the pulser ring in a phase displaced manner. The projections (radial teeth) 20b of the member 20 form a first magnetic circuit which passes through the coil 22, while the projections (teeth) 21b of the member 21 form a second magnetic circuit which alternately bypasses the coil. As the pulser ring rotates, its wall portions 11b come alternately into a first position in which they are opposite the projections 20b and a second position in which they are not opposite the projections 20b but are opposite the projections 21b. The reluctance of the second magnetic circuit is then lower than that of the first magnetic circuit. The effect is to increase the output voltage from the coil. A number of embodiments are described.

Title: Solid concentration measuring device
Inventor: PARISH GEORGE KEITH
IPC: G01N15/06
Filed: 1996-05-09
Abstract: A measuring device 1 for measuring the concentration of solids in a liquid, such as particles in liquid toner in the case of copiers or printers, uses a variable capacitor having a movable upper plate 5 which is allowed to fall towards a lower plate 3 as the liquid flows out from between the plates. The capacitance between the two plates is measured, and the time for the plate 5 to move between two predetermined values of capacitance is used as a measure of the liquid viscosity and therefore of the solid concentration. As described the plate 5 is raised by a cam on the shaft of an agitator motor, fresh fluid being drawn into the space between the plates through a valve 9. A microprocessor (30, Fig.3) receives the capacitance measurement and a liquid temperature signal, and controls a system which tops up the toner or carrier fluid as required.

IPC: F21W107/10
Filed: 1996-07-17
Abstract: A vehicle lamp includes a reflection mirror, a front lens, and a light source arranged between the reflection mirror and the front lens, the central axis of the light source is perpendicular to the principal optical axis of the reflection mirror, on the reflection mirror, there is formed a reflection surface composed of a large number of reflection steps which are defined by portions of paraboloids of revolution and are formed between adjacent ones of closed curves. The closed curves are obtained as lines of intersection between a fundamental reflection surface and a group of paraboloids of revolution composed of a large number of paraboloids of revolution having different focal distances. Centers of the group of closed curves forming the boundaries of the reflection steps are arranged at a position distant from an intersection at which the principal optical axis of the reflection mirror crosses the reflection mirror, and square lens steps are formed on the front lens. Due to the foregoing, the arrangement of the image of the light source that has been projected by the reflection steps tend to be matched with the sections of the lens steps formed on the front lens.
