Title: Retaining mechanism for a tooth assembly
Inventor: GARMAN JAMES A
IPC: E02F9/28
Filed: 1992-06-22
Abstract: Retaining mechanisms are normally utilized for securing a tooth to an adapter. Many times the forces necessary to secure the retaining mechanism in an assembled position is not high enough to maintain assembly during use. In the subject arrangement, the retaining mechanism (16) includes a pin (40) having a means (60) thereon for forming a shoulder and a plurality of conical spring washers (42, 44, 46) each having an inner surface (52) defining an opening (53) having a diameter of a predetermined size which is smaller than the outer diameter of the shoulder means (60). During assembly, the shoulder means (60) of the pin (40) is forced through the opening (53) of the respective conical spring washers (42, 44, 46) from a concave side (48) thereof. In order to disassemble the pin (40), the shoulder means (60) of the pin (40) must be forced through the respective openings (53). In instances where the pin (40) must be removed from the same side that it is installed, a much higher force is required to force the shoulder means (60) through the opening (53) of the respective first, second, and thrird conical spring washers (42, 44, 46). Consequently, a retaining mechanism (16) is provided which has very high resistance to inadvertent disassembly during use.

Inventor: SHIBAYAMA HIROAKI
IPC: G08B5/22
Filed: 1993-10-22
Abstract: A radio paging receiver enables an user of the receiver later to see a received message even when an alert stopping operation or message confirmation operation is first executed in an environment too dark to see the received message. The receiver has a photosensor for detecting whether a display environment is light or dark. If the alert stopping operation is executed in the dark condition, the received message is stored in a memory as an unconfirmed message, so that the user later can see and read the received message in a light condition after a change of the environment. In addition, when the environment is changed from a dark condition to a light condition, if an unconfirmed message exists in the memory, the receiver alerts the user.

Title: Method and apparatus for folding wing portions of flat dough members
Inventor: BRINK POUL E
IPC: A21C11/00
Filed: 1992-06-29
Abstract: In the production of various kinds of pastry it is actual to effect a folding-over of wing portions of flat dough members, such that these portions are folded down over some stuffing deposited e.g. on a middle area of the dough member. While this is easily done manually, it has been very difficult to automatize the operation, but according to the invention this is achieved in a very simple and efficient manner. A rubber resilient shaping plate is used, which, through foldable areas, is connected with projecting wing portions each associated with a depending rubber rod. At their lower ends these rods are rigidly attached to an actuator plate, which, in being raised relative to the shaping plate, urges the rubber rods upwardly for folding the wing portions up- and inwardly. Hereby the rubber rods will be bent, and due to the tensions thus produced a further raising of the actuator plate can result in the rods causing the wing portions to be folded inwardly over and down towards the shaping plate.

Title: Sideframe with Increased Fatigue Life
Inventor: WRONKIEWICZ ROBERT D
IPC: B61F5/52
Filed: 1994-03-03
Abstract: The present invention involves structurally changing an American Association of Railroads (AAR) standard 100 ton sideframe so that it is statically and dynamically capable of handling a 110 ton payload; this is accomplished by reducing two weak points on the sideframe.  The first weak point is located in the sideframe upper compression member, near the vertical support column, and the second weak point is the upper portion of the area comprising the lower diagonal tension member core support hole.  Stresses in this area are reduced by gradually extending the zone where cross-sectional wall thicknesses normally experience an abrupt change.  The gradual decrease in cross-sectional areas increases the static strength of the sideframe by increasing the elastic or ultimate loading limits.  In the second area metallic mass is added, thereby increasing the section modulus of the sideframe near the core support hole.  Increasing the section modulus increases the number of flexure stresses which the improved AAR standard 100 ton sideframe can withstand, allowing this sideframe to meet AAR dynamic testing standards set for a 100 ton sideframe, even though it's loaded with 110 tons of payload.

Filed: 1994-10-11
Abstract: A missile includes an optical fiber canister with the optical fiber wound as an annular fiber pack having an initial payout region extending from the inner annular surface. A reinforcing leader overlies the initial payout region of the optical fiber to form a leader composite structure. The leader composite structure is wound into a flat outwardly spiraling coil lying perpendicular to the axis of symmetry of the annular fiber pack, with the outer turn of the spiral leading away from the optical fiber pack. The coil is encased in a mass of potting compound. At the initiation of optical fiber payout, the turns of the coil progressively tear free of the mass of potting compound to achieve a gradual loading of the optical fiber and opening of a path for the axial payout of the portion of the optical fiber not protected by the reinforcing leader.

IPC: F03D7/02
Filed: 1992-09-17
Abstract: A controller (30) and method is disclosed for a variable speed turbine (10) to track wind speed fluctuations for greater efficiency. The controller (30) controls the rotor (22) speed in accordance with a wind speed supplied by a wind observer (40) in order to approximate the varying wind speeds. The wind observer (40) predicts the average wind speed at a subsequent point in time over cross-section. Data is applied to a parameter schedule (42) determining desired rotor (22) values. Load torque is controlled where desired rotor speed is approximated. Wind speed prediction is repeated at each subsequent time intervals to control load torque and rotor speed. Aerodynamic torque and net torque are calculated.  Wind speed prediction is based on (previously predicted) wind speed and correction terms including net torque and the difference between the predicted and actual rotor speed.

Title: No-Till Seeder and Fertilizer
Inventor: POIRIER GERARD H
IPC: A01C7/06
Filed: 1994-03-29
Abstract: A seed and fertilizer boot is mounted on a conventional cultivator shank. The boot has side-by-side fertilizer and seed tubes. One tube leads to a downwardly and rearwardly sloping delivery spout while the other delivery tube projects below the delivery spout. A flat knife is mounted on the front of the straight delivery tube to form a narrow furrow immediately in front of the associated delivery tube for receiving seed or fertilizer from the tube. The knife is adjustable along the tube so that its depth can be adjusted to compensate for wear. A second knife extends along the front face of the delivery spout to form a second furrow immediately beside the first furrow. This closes the first furrow and packs the soil onto the planted seed or fertilizer. The second knife also provides a shallower furrow for planting fertilizer or seed as the case may be. Like the first knife, the second knife is adjustable. Where desired, a skid-type packer can be mounted on the shank to close the furrows.
