Title: Cam operated workpiece engaging apparatus
Inventor: JACKSON DONALD T
IPC: B23Q7/04
Filed: 1991-04-04
Abstract: CAM OPERATED WORKPIECE ENGAGING APPARATUS           ABSTRACT OF THE DISCLOSURE         A workpiece engaging apparatus includes a drive having a linearly reciprocal drive member.  Two workpiece engaging members are arranged in opposed, inverted relationship with respect to each other and pivotally connected at one end to the drive.  Each workpiece engaging member includes a workpiece engaging surface and at least one cam.  In one embodiment, the cams in each of the first and second workpiece engaging member are identically constructed, but are disposed in opposed, invert-ed relationship with respect to the cams in the opposed one of the first and second workpiece engaging members.  Cam follower members mounted on the linear drive member engage the cams during reciprocal movement of the drive member to pivot the workpiece engaging surfaces of the first and second workpiece engaging means between open and closed workpiece engaging positions.  In another embodiment in which the apparatus is designed to perform a hemming operation on overlapping sheets, a first cam is formed in each of a pair of block members secured to the linear drive member.  The block members are pivotally connected at a first end to the linear drive cylinder.  Spaced, outer plates, each having a second cam formed therein, are also pivotally connected at one end to the linear drive cylinder and carry a workpiece engaging member at an opposite end.  Linear movement of the cam follower driven by the linear drive member causes the outer plates to pivot between an open position and a closed, workpiece engaging position.

Title: Rotary locking system with metal seals
Inventor: DOLLISON WILLIAM W
IPC: E21B17/06
Filed: 1991-07-11
Abstract: ROTARY LOCKING SYSTEM WITH METAL SEALS            ABSTRACT     The locking system utilizes metal seals for sealing and a rotary locking mandrel (15) which is rotated by a rotary running tool (27) to lock in a landing nipple (10) in a well conduit.  The lock mandrel has a metal sealing surface (26a) sealingly engageable with a metal seat (14h) in the landing nipple and orientors (20) on a number of helically profiled segments (19) which are rotatably engageable with mating profiled segments (14) in the landing nipple.  As the lock mandrel is lowered on the running tool into the landing nipple, the lock mandrel segments (19) are oriented between nipple segments (14), and the mandrel metal sealing surface (26a) engages the metal seat (14h) in the landing nipple.  Downward jarring on the running tool rotates the mandrel segments into engagement with the landing nipple segments, locking the lock mandrel in the landing nipple, sealingly engaging the metal seal surface (26a) on the metal seat (14h) and releasing the running tool (27) from the locking mandrel for retrieval from the well conduit.

Title: Gas insulated electric apparatus
Inventor: ENDO FUMIHIRO
IPC: H02B13/065
Filed: 1991-09-12
Abstract: In a gas insulated electric apparatus having a plurality of gas sections filled with insulating gas, locating device orientates position of a gas section, in which insulation abnormalities are produced, on the basis of a detection signal from sensors disposed in each of predetermined gas sections and at the same time hindering degree diagnosing device diagnoses the degree and the kind of the insulation abnormalities, while comparing a detection signal from the sensors with data stored in a data base. A valve control generates a valve control signal, responding to the locating device and the hindering degree diagnosing device and trip circuit generates a valve opening signal for opening an electromagnetic valve disposed in a gas section, in which insulation abnormalities are produced, responding to this valve control signal.          Insulating gas injecting and evacuating device injects an insulating gas different from the insulating gas, with which the gas sections are filled beforehand, in the gas section, for which the electromagnetic valve opened by the valve opening signal is disposed, or evacuates a predetermined amount of the insulating gas, with which the gas sections are filled beforehand, so as to increase insulation strength.

Patent CA-2054038-A1 (CA)
Inventor: ONISHI MASASHI
IPC: H01S3/06
Filed: 1991-10-23
Abstract: Abstract of the Disclosure An optically active device comprising an optical fiber, a light source and a coupler is disclosed.  The optical fiber has a core made of a silicate glass containing Rb and/or Cs oxide.  The core is doped with Nd3+ as an active ion and transmits light at 1.3 µm band.  The light source generates excitation light at 0.8 µm.  The coupler directs the excitation light from the light source into the core of the optical fiber.  A signal light or a spontaneous light at 1.3 µm band which is transmitted in the core stimulates Nd3+ to emit light at 1.3 µm band.  As a result an optical function such as optical amplification can be effected at 1.3 µm band.

Title: Non-fat cream cheese product and method for manufacture thereof
Inventor: CRANE LORI A
IPC: A23C19/076
Filed: 1992-07-14
Abstract: In the method of the present invention for making a non-fat cream cheese product, a fermented skim milk retentate is introduced into a mixing tank provided with agitation means. The skim milk retentate is agitated and transferred through a recirculating loop as dry cottage cheese curd and an emulsifying salt are added to the mixing tank. Agitation and recirculation are continued for a period of time sufficient to provide a dispersion of the dry cottage cheese curd and emulsifying salt homogeneously throughout the retentate. Heating of the dispersion is then started by injecting steam into the dispersion as it passes through the recirculating loop. While the temperature of the dispersion is within the range of from about 70° F. to about 150° F., non-fat dry milk is added to the dispersion. Agitation and heating is continued until the dispersion temperature is within the range of from about 140. degree. F. to about 165° F.      Xanthan gum, as the first gum of a stabilizing system, is then added to the mixing tank. Agitation and heating is continued until the dispersion temperature is in the range of from about 165° F. to about 190. degree. F. The steam is shut off and salt, sugar and carrageenan, as the second gum of a stabilizer system, are added to the mixing tank. Agitation is continued for a period of from about 1 to about 4 minutes to provide a non-fat cream cheese mix. The cream cheese mix is then homogenized to provide a non-fat cream cheese product.
