Title: Tape winding devices
Inventor: SHIRAISHI YASUSHI
IPC: G11B15/32
Filed: 1997-08-25
Granted: 2002-03-12
Abstract: A thin ribbon cassette (16) is set on a tape winding device and its vertical-direction position is fixed by a position restricting member (18) provided on a back of a cover for an apparatus body. When the ribbon cassette (16) is thin in correspondence to a narrow width of an ink ribbon (15), a quantity of lowering of a ribbon winding top (5) engaged with a reel (16-1) of the cassette (16) is small. The biasing force of a clutch spring (7) compressed depending on the quantity of lowering of the ribbon winding top (5) is small, the force of a winding drive gear (6) which presses a clutch plate (4-1) through a felt (12) is small, the frictional force of the felt (12) is small, and the torque of the rotational shaft (4) is small. This torque is just suitable for winding an ink ribbon narrower long ink ribbon having a corresponding small tensile strength.    When a thicker ink ribbon cassette (22) is set on the apparatus body, the quantity of lowering of the ribbon winding top (5) is large, and the biasing force of the clutch spring (7) is correspondingly large, so that the torque of the rotational shaft (4) is large in correspondence to a long wide ink ribbon (21). In alternative embodiments, the clutch plate (4-1) is replaced by a clutch plate (20-1) provided on a short rotational shaft (20), with a short ribbon winding top (34) being mounted on the shaft (20) to be axially slidable, but non-rotatable, relative to the shaft (20).      A longer rotational shaft (14) is disposed within the shaft (20) and has an annular clutch plate (14-1) surrounding the clutch plate (20-1), a longer ribbon winding top (30) being mounted on the shaft (14) to be axially slidable, but non-rotatable, relative to the shaft (14) .

Title: Aerator valve assembly
Inventor: BURKHART JAMES R
IPC: F16K21/00
Filed: 1998-05-20
Granted: 2001-12-11
Abstract: An aerator valve assembly adapted to provide selective fluid communication between a supply of pressurized gas and a pressure vessel and adapted to provide selective fluid communication between the pressure vessel and a bulk material handling structure. The valve assembly includes a valve housing including a valve body, an end cap adapted to be connected to the supply of pressurized gas, and a piston seat having an outlet port adapted to provide fluid communication with the bulk material handling structure. The valve body includes a port adapted to provide fluid communication with the pressure vessel. A piston is located within a chamber of the valve body between the end cap and the piston seat. The piston is selectively slidable between an extended position wherein the piston creates a metal-to-meta1 seal with the piston seat to seal the outlet port closed and a retracted position wherein the seal is broken. The piston includes a diaphragm that is adapted to engage the piston seat and that includes a plurality of fluid passages adapted to provide fluid communication between the supply of gas and the port of the valve body. The piston includes a cylindrical skirt extending from the diaphragm that slidably engages a bearing on the interior wall of the valve body to provide proper piston alignment. A  biasing member extends between the piston and the end cap and resiliently biases the piston from the retracted position to the extended position.

Title: Digital video security system
Inventor: BAKSHI RAJEEV K
IPC: G08B13/196
Filed: 1998-07-06
Granted: 2001-10-23
Abstract: An embedded system for video monitoring and security is disclosed. The embedded system includes a video camera, a user programmable motion detection sub-system which activates the camera and a solid state storage mechanism for collecting the digital video images. All three of the functional units as well as additional hardware and software required for image analysis, compression, storage, playback, and a user interface are all contained within the same vandal resistant enclosure, which is relatively small and easily mountable to almost any surface. Digital video images captured by the camera are processed and continually monitored for unexpected motion. The required memory capacity is reduced by storing the video images in a "time lapse" fashion and storing only when the storage subsystem is triggered by the motion detection subsystem. The solid state storage media provides for increased reliability over older mechanical forms of memory. The user interface takes the form of an on-screen display, where the user can program many system features including: aspects of the motion detection and storage subsystems.

Abstract: A delay-locked loop (DLL), including frequency detection logic and a phase detector, is described having an operating range as wide as a conventional charge pump phase locked loop. The frequency detector logic counts the number of rising edges of the multi-phase clocks generated from a reference clock during one period of the reference clock. A loop filter is used to adjust the frequency of each multi-phase clock until frequency lock is obtained by comparing the number of rising edges.  After frequency lock, phase detection logic is used to finely tune out the remaining phase error.
