Title: Direct reading dosimeter
Inventor: THOMSON IAN
IPC: G01T1/24
Filed: 1991-07-05
Abstract: ABSTRACT   The invention relates to a radiation dosimeter having a pair of insulated gate field effect transistors integrated into the same silicon substrate, in which each of the transistors are operable in a bias mode and a test mode. A means for biasing each of the transistors, during the test mode is provided, so that one of the transistors is more sensitive to ionizing radiation than the other of the transistors. A means is provided for determining, during the test mode, the difference in the threshold voltages of the transistors, whereby the difference voltage is indicative of the radiation dose, and a means is provided for continuously switching the transistors between the bias mode and the test mode, whereby the period of operation of the transistors in the test mode time period is small in comparison to the period of operation of the transistors in the bias mode.

Title: Clip-on handle for baseball caps
Inventor: MOUSSEAU GILLES A
IPC: A42B1/24
Filed: 1992-07-27
Abstract: Abstract On the plastic handle used to clip on to the baseball cap's beak in order to make a secure catching device out of the cap, one that can be used by either left or right hand, and one that can give much more range to the man, woman or child baseball fan who is in a position to catch a stray baseball coming his or her way, it is known to have a knob at the and of it, so that it does not slip from the hand when the force of the ball is applied in the process of catching the ball. This clip-handle is also known to have on one of the extremities on one side of it a 180° hook of sufficient diameter to grasp firmly the band and the seam of the cap from the inside. In this way, when force is applied, the rigid but not brittle plastic hook does not slip off, but rather digs in more into the band and seam of the cap The other side of this clip-handle, opposite the hook, is also known to have a hot dog shape that is of the approximate size and curvature of an average baseball cap so as to facilitate the positioning of the cap opening when catching a baseball from any angle and to give it stability.

Title: Method for grinding plastics or glass
Inventor: RUDOLF BORIS E
IPC: B24B7/30
Filed: 1992-07-31
Abstract: Abstract Method for grinding plastics or glass The invention proposes a method for grinding plastics or glass, in particular for grinding acrylic glass, where a mechanically driven grinding tool is moved across a surface to be finished (44). Grinding is effected by a dry process, without any liquid working agent, the grinding tool performing an orbital movement, or oscillating about a fixed rotary axis at high frequencies, while the grinding dust is extracted from the marginal area. The grinding tool comprises a closed abrasive with resiliently embedded abrasive grains, a plurality of the resiliently embedded abrasive grains having, preferably, level front surfaces which are delimited by relatively sharp edges at the transition to their lateral surfaces, the greatest part of the front surfaces being oriented to extend substantially in parallel to the surface to be worked (44). The method enables plastic and glass surfaces to be micro-finished to a particularly high grade (fig. 1).

Inventor: ANSTEY HENRY D
IPC: A01F15/07
Filed: 1992-11-20
Abstract: A large round baler is equipped with a wrapping mechanism for applying a web of plastic material to a bale located in the bale-forming chamber.  The wrapping mechanism includes a housing including a cover mounted to the rear of the discharge gate of the baler for pivoting vertically, about a first horizontal transverse axis at an upper forward location of the cover, between a lowered closed position, wherein it encloses a roll of wrap material resting on a pair of roll end supports, and a raised position permitting access to the roll end supports.  A pair of gas springs are coupled between opposite side walls of the cover and spaced apart crank arms of a load member which is vertically pivotally supported from the gate for swinging about a second horizontal transverse axis located slightly below and rearwardly of the first axis. The disposition of the gas springs relative to the first and second axes is such that the springs act to maintain a load bar of the load member urged into contact with a roll of wrap material supported on the roll end supports when the cover is in its closed position and acts to pivot the load member so as to dispose the load bar thereof in a raised inoperative position in response to the cover being raised to its open position, the springs also acting to maintain the cover in its raised position.

Title: Gas fired convection oven
Inventor: PRABHU GAJANAN M
IPC: F24C15/00
Filed: 1993-01-29
Abstract: ABSTRACT OF THE DISCLOSURE A convection oven is given a lower profile so that two ovens may be stacked without exceeding a height so that the uppermost of the stacked ovens may be comfortably reached by a relatively short person.  Also, the oven requires less floor space for installation and operation.  The height of the oven is reduced by placing inshot burners at an inlet to the oven.  Heretofore, the burners were placed under the oven, which increased the space which must be provided to enclose the burner, and therefore the overall height of the burner.  The height of the oven is reduced by allowing the flue gas flow from front to rear before entering the cooking cavity.  Heretofore, the flue gas flowed from under the cooking cavity to the sides and up towards the top of the cooking cavity.  From there, it traveled to the top of the cooking cavity before entering the cooking cavity itself.

Filed: 1993-01-29
Abstract: An improved method for making a composite tube (10) to a carbon steel tube (16) joint or a composite tube (10) to a carbon steel header (50) joint is achieved by specially preparing the composite tube (10) by removing the cladding (12) from one end (24) to a predetermined length to provide base carbon steel material (14).  The end (24) of the composite tube has cladding (12) tapered at a predetermined angle.  This end (24) is then expanded.  The composite tube (10) is then welded to the carbon steel tube (16) with fewer weld passes while also eliminating the stainless steel weld pass.
