Abstract: Abstract An annulus pressure operated ratchet device for use in a well bore.  A mandrel includes an upwardly-directed elastomeric cup which is slidingly received over the mandrel.  A sleeve is slidingly received over the mandrel beneath the cup and a ratchet disposed between the sleeve and the mandrel permits only downward movement of the sleeve.  An elastomeric packer is received about the mandrel between the sleeve and an upwardly-directed shoulder.          Annulus pressure urges the cup and sleeve downwardly to compress the packer thereby sealingly engaging it with the casing.  The shoulder beneath the packer is threadably engaged with the mandrel by a left-hand thread.  Right-hand mandrel rotation unthreads the connection thereby releasing the packer.

Granted: 1992-04-14
Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a steam-shower apparatus and method including a supply of steam which is fed through a Coanda nozzle and along a path running parallel with one surface of the apparatus.  The sheet to which the steam is to be applied runs parallel to this same surface of the machine, but in a direction opposite to the direction of the flow of steam.  The sheet travels along a path spaced slightly from the surface of the machine, and the flow of steam runs the entire length of this surface heating the sheet as it flows in the opposite direction.  The apparatus may be divided into several sections so that the sheet may be profiled along certain regions which are defined by these sections.  In addition, means are included for altering the volume of flow to any one of the particular sections.

Title: Single chip transponder device
Inventor: CARROLL GARY T
IPC: H01Q1/22
Filed: 1987-07-16
Granted: 1991-06-18
Abstract: ABSTRACT OF THE DISCLOSURE A transponder device (14) receives a carrier signal (16) from an interrogator unit (12).  This carrier signal, of frequency F, is rectified by a rectifying circuit (22) in order to generate operating power.  Logic/timing circuits (24) derive a clock signal (28) and second carrier signal of frequency F/n from the received carrier signal. This clock signal reads a unique identifying data word from a programmable read only memory (PROM), which is park of a data generator (30).  The data word is encoded and mixed with the carrier signal in a balanced modulator circuit (22).  The output of the balanced modulator (18) is transmitted to the interrogator unit, where it is decoded and used as an identifying signal.  The identifying signal identifies the particular transponder device from which it originated.  The rectifier and balanced modulator circuits (22) are realized from the same diode elements.  All electrical circuits of the transponder device are realized on the same monolithic semiconductor chip (98).  In one embodiment, an antenna receiving/transmitting coil  (20) is also part of the chip, being placed around the periphery thereof.  In alternative embodiments, various hybrid elements may be connected to the monolithic elements in order to realize additional functions, such as adjustable tuning of the receiving circuit, independent crystal frequency control, and battery-powered operation.

Title: Partial eyeshield
Inventor: ARMSTRONG JEFFREY A
IPC: G03B13/04
Filed: 1987-11-09
Granted: 1992-08-04
Abstract: PARTIAL EYESHIELD      Abstract A partial eyeshield is attached to a sighting device, for example a video camera. The eyeshield is constructed so that it covers a portion of the field of view of the user's nonsighting eye. That portion of the nonsighting eye's field of view corresponds to a portion of the field of view of the sighting eye the user desires to view without closing his nonsighting eye. So covering the nonsighting eye causes the corresponding field of view in the sighting eye to dominate, while leaving substantial usable vision through the nonsighting eye.
