Abstract: Abstract of the Disclosure IMPROVEMENTS IN OR RELATING TO ELECTRONIC MOTOR CONTROLS, LAUNDRY MACHINES INCLUDING SUCH CONTROLS AND/OR METHODS OF           OPERATING SUCH CONTROLS A control  apparatus  and method for an electric motor having sensing devices which sense the frequency and polarity of EMFs in the rotor windings down to a condition where the rotor is in condition for reversing, and causing reversing of the motor when the frequency is such as to allow reversing and the polarits of a selected winding is at or near a zero crossing between positive and negative polarities.   Cyclical reversal is effected by measuring the time the rotor takes to coast from a "power off" condition to the condition for reversing and with  an electronically  commutated motor reversing  can usually be effected in one commutation period.  The motor is used in a clothes washing machine or similar application where rapid reversal is required or timing of the time from one reversal to the next is required to be constant.

Title: Lens shutter camera including zoom lens
Inventor: HARAGUCHI KEISUKE
IPC: G02B23/14
Filed: 1987-05-12
Granted: 1993-01-05
Abstract: IN THE ABSTRACT    A lens shutter type of camera is disclosed in which a zoom lens is positioned in a lens block (1) which has a sector gear (15) rotatably associated with the lens block and with a rotatable cam ring (14).  The cam ring and sector gear  are rotatable  in a substantially constant axial position.   A movable finder optical assembly (8) and a movable strobe assembly (9) are movable in association with movement of the zoom lens.  The zoom lens is movable between an extreme telephoto position and an extreme wide angle position,  as well a into a fully collapsed lens position beyond the extreme wide angle position and a macro or close-up photographing position beyond the extreme telephoto position.   When the camera is in its macro mode, a prism (P1) is inserted into the finder optical assembly to correct for parallax; the strobe assembly is moved to change its illumination angle; and an optical wedge  (4e)  is pivoted into the path between a light receiver (4) and a light emitter (3e).  A single cam plate (53) is provided to move the  finder assembly and the strobe assembly.   The photographic aperture  (22b)  can be selectively closed by barrier plates (31a) when the zoom lens is moved into its fully collapsed position.   A light intercepting assembly (210)  is provided for preventing light from entering the photographic optical assembly via cam grooves (20 and 21). This intercepting assembly includes a flexible code plate (90) which surrounds a peripheral portion of the cam ring (14) and which provides positional information relating to the position of the zoom lens.

Title: Dynamic memory management system and method
Inventor: STEWART DARRYL J
IPC: G06F12/10
Filed: 1988-07-15
Granted: 1993-07-20
Abstract: ABSTRACT     A system and method for allowing dynamic configuration of the translation entries within a memory management system of a computer.   In the disclosed embodiment, portions of a logical  address  from a CPU are defined as offset,  page, volume/page,  and  volume  fields.    The  offset  field  is presented unaltered to a main memory to select a specific location within a page of memory.   The page field forms a first portion of the address of a selected entry in the translation memory.  The volume/page field is combined with the contents of a base register as specified by the contents of a mask register  to form the  remaining portion of the address of a selected entry in the translation memory.  The volume field and volume/page fields are compared to one or more tags stored in the translation memory to determine if a match  exists.    If  a  match  exists,  the  frame  pointer associated with the matching tag is output to main memory as the physical address of  the frame containing  the desired page.

Granted: 1992-07-21
Abstract: METHOD AND APPARATUS FOR PHOTOGRAPHING A MOVEMENT               ABSTRACT OF THE DISCLOSURE      Method and photographic apparatus for performing motion studies on a moving subject.  The moving subject is photo-graphed through a rotating disc having at least one transparent aperture and a plurality of filter apertures covered with filter plates.  Opaque regions of the disc separate the aper-tures from one another.  Preferably, miniature spotlights are connected to moving points of the subject that are desired to be studied.  Each of the spotlights projects a beam having essentially one selected wavelength to pass through the filter apertures and the filter plates.  Incident background light, lighting the subject, is prevented from passing through the filter apertures by virtue of the filter plates.  As a result, a photograph produced by the camera includes a series of light-streak images produced by the motion of the spotlights and the light emitted by the spotlights entering the filter apertures.  Interruptions in the light-streaks are produced by the opaque regions of the disc.  Additionally, the photograph also includes a series of stroboscopic images of the subject produced by the incident background light reflecting from the subject and entering the camera through the transparent aper-ture.

Abstract: A passive, all optical communications network is provided in which a single optical source in a central station serves many outstations (eg telephones in customers' premises).  Time division multiplexed optical signals from a laser source are transmitted along a single optical fibre (14) from a central station (4).

At this stage there are 120 individual fibres to customers' premises (8).  Digital speech or data is sent back to the central station by a laser in the customers' premises operating in a low duty-cycle mode.  The 120 data streams are interleaved at the branching points.

Abstract: - 19 -                   53,933 ABSTRACT OF THE DISCLOSURE      A steam turbine inlet valve control system includes separately tunable valve characteristics for single valve and sequential valve operation modes. The sequential valve characteristics include both normal and alternate sequences which can be selected during operation of the steam turbine.  The characteristics may be displayed to an operator and modified by graphical manipulation to simplify tuning the control system's characteristics to the steam turbine's operation.  The control system also performs direct tracking of flow through the valves by converting sensed position signals to individual valve flow signals using a lift-to-flow conversion characteristic.  Individual valve flow signals are summed and corrected for choked flow conditions to produce a tracked flow demand signal.

Abstract: A method and apparatus for the generation of reports. The voice signals including predetermined trigger phrases are transmitted from an input device such as a multiline telephone to a voice recognition system.  The voice recognition system associates the trigger phrases with predetermined blocks of text message and in response to a sequence of trigger phrases, creates a report.  The text is then output to a voice synthesizer system for the creation of synthetic voice signals corresponding to the full text of the report and the synthetic voice signals are output to a voice storage and forward system for later retrieval. The system also provides a printed copy of the full text of the report. In one embodiment of the system, an exception dictionary is provided which substitutes replacement words having a modified spelling for exception words whose pronunciation, as synthesized by the voice synthesizer, is not considered acceptable.

Abstract: A  downhole  oil  well  tool  uses  impact,  reciprocal drilling  and  an  improved  rotating  bit  or  like  working member,  receiving both fluid pressure and weight from an elongated pipe string with a flow bore in order to drive the tool.  A valve within tool housing controls fluid pressure to the working end  so that the tool pressures up,  then releases pressure through the working member allowing the pipe string to load the bit,  creating impact.   A clutch rotates  the  working  member  during  drilling  to  prevent imprint upon the formation.
