The leg of the voltage divider on the collector side of the first transistor includes two serial connected resistors.  A second capacitor is connected between (a) the point between the two serial connected resistors in the leg of the voltage divider on the collector side of the first transistor, and (b) the common terminal of the primary winding of the transformer and of the switching transistor.

Abstract: DOOR CHECK            Abstract of the Disclosure:        A door check provides a positive stop at a hold open position, as well as being disengageable to provide a fully open position, and is automatically reengageable upon door closing.  A check strap is pivotally mounted to a vehicle body and resiliently biased into sliding engagement with a stop pin fixed to the vehicle door.  As the door is opened, the stop pin slides along a working surface of the check strap, and into a catch portion hook to block the stop pin and provide a positive stop to maintain the door at a hold open position.  The door may be moved back toward closed position to move the stop pin out of the hook, and the check strap moved by an external force away from the stop pin enough that the stop pin will miss the hook as the door is moved back to the hold open position.  From there, the door can be moved to a fully open position, as the stop pin slides along the surface of a keeper portion on the check strap.  The keeper portion surface is oriented so that the stop pin will slide over the catch portion and automatically back into engagement with the working surface under the resilient bias as the door is closed.

Title: Method and device for recording and replaying audio communications
Inventor: LEUNG KEITH K W
IPC: H04M1/656
Filed: 1987-04-28
Granted: 1991-05-14
Abstract: ABSTRACT OF THE DISCLOSURE Methods and devices for recording and replaying audio or voice communications are disclosed.  A device according to the invent on is compatible with conventional magnetic tape loggers.  Such a device is termed a message repeater, and it records and replays audio signals forming messages on a message channel, such as a telephone line or a radio channel.  The message repeater includes circuits for converting the audio signals on a particular channel into corresponding digital signals and circuits for storing the digital signals.  The message repeater also includes circuits for selectively recalling the signals that were stored and circuits for converting the signals that were recalled into analog audio signals.  The analog audio signals may be sent to a speaker, a headset, or another recording device, such as a cassette recorder.  Hence, messages on the selected message channel may be recorded and later replayed by the message repeater.  Preferably, the message repeater includes a display with indications of the relative locations and lengths of the stored messages as well as a cursor or index.  Furthermore, the message repeater preferably permits a selected message to be saved, thereby allowing the selected message to be replayed at the convenience of the operator.  Additionally, the message repeater advantageously has fault detection circuits for determining if a fault has occurred in the other circuits.          For instance, a relatively low audio frequency signal may be generated in the message repeater.  This signal is converted into corresponding digital signals, which are stored and then recalled.  After these signals are recalled, they are converted to an analog audio signal, which is supplied to a sensing circuit.  Moreover, a predetermined pattern of bits may be stored and retrieved.  The data retrieved from storage is compared to the predetermined pattern of bits to check for proper storage operation.

Abstract: Resinous particles carried on the respective grain surface with a metal compound through a metal ester bonding, and preparation methods thereof, said metal compound having a biological activity, above all, against harmful livings, and said preparation method comprising forming a metal ester bonding by reacting a metal compound with resin particles having a mean grain diameter of 0.01 to 250µ and bearing organic acid group(s) in the form of free acid or salt on the respective grain surface thereof.          Said resinous particles are characterized by having metal compound(s) only on the respective grain surface, and therefore, the amounts of metal compound required for the preparation of hydrolyzable resinous particles are greatly reduced as compared with those of the heretofore proposed metal containing resinous particles.

Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE       An ankle brace for constraining movement of the lower leg and foot about the normal horizontal axis of rotation of the ankle while inhibiting other rotation or extension or retraction movement about abnormal axes or in abnormal directions in order to help prevent injury to the ankle joint.  The device includes a U-shaped leg member positionable in straddling relationship to the ankle joint and fixable to the lower leg.  An ankle member is connected by a sliding pivot to the U-shaped leg member and is engaged with respect to the foot to hold the foot and lower leg together for movement about an arcuate path described by the sliding pivot joint.

Title: Method of measuring viscosity of a body
Inventor: GREGO GIORGIO
IPC: G01J3/44
Filed: 1987-11-27
Granted: 1992-07-14
Abstract: Abstract The method of measuring viscosity of a body exploits the scattering effects the body introduces into a substantially monochromatic radiation passing through it: more particularly, the width of the spectral line due to Brillouin scattering is measured.  The temperature of the body can be determined too, by measuring also the width of the line generated by Rayleigh scattering.  The method is of particular interest for measurements on glasses.
