Abstract: BUILT-IN RACK APPARATUS                   ABSTRACT OF THE DISCLOSURE    For breaking out a drill rod joint, a hydraulic chuck is mounted by a housing for clampingly engaging a drill rod and rotation to break a rod joint, the chuck being rotated by a first gear that is bolted to a drive tube which mounts the chuck.  A hydraulic motor drives a second gear within the housing for rotating the first gear.  A rack is mounted for tangential movement by a race mount which is movable radially inwardly to move the rack teeth for engaging the first gear teeth while first spring mechanism constantly resilient urge the rack mount to a retracted position such that the rack teeth are not engagable with the gear teeth even though the rack is tangentially moved by a first hydraulic ram that is operable for moving the rack to a tangential advance position. Second spring mechanism urges the rack radially outwardly, a second ram being operated to radially move the rack mount and thereby the rack to have the rack teeth engagable with the gear teeth.          Hydraulic controls automatically operates the second ram to move the rack inwardly and thereafter the first ram tangentially to apply a rotary force to the gear teeth in the event the motor is not able to initially start the rotation of the second gear to start the breaking out of a rod joint.

Title: Magnetic recording medium and information recording-reproduction method using the same
Inventor: NAKAJIMA JUNSAKU
IPC: G11B13/04
Filed: 1991-08-09
Abstract: A magnetic recording medium has a recording layer made up of a ferrimagnetic material whose compensation temperature is substantially within room temperatures, and an information recording-reproduction method uses the magnetic recording medium. During recording, while a light beam is projected on the recording layer so as to raise the temperature of a recording portion, information is recorded by applying a signal magnetic field from a magnetic head. During reproduction, while a light beam is projected on a reproducing portion of the recording layer so as to raise the temperature thereof, information is reproduced by detecting leakage flux from the reproducing portion by the magnetic head. Thus, during reproduction, no magnetic flux is generated from other portions of the recording layer not irradiated by the light beam. With the arrangement, crosstalk due to leakage flux from adjoining tracks not irradiated by the optical beam can be eliminated.      Therefore, track pitches can be made narrower so as to increase recording density of the magnetic recording medium. Further, since crosstalk from adjoining tracks is eliminated, a high S/N can be achieved.

Title: High power electrical machinery with toroidal permanent magnets
Inventor: LEUPOLD HERBERT A
IPC: H02K31/02
Filed: 1992-01-09
Abstract: A pair of hollow permanent magnets mounted to form a toroidal stator having cylindrical gaps and apposed cavities. The magnets are polarized such that their magnetic flux passes in one direction through the gaps to intersect the rotar along two cylindrical bands and then passes through the magnetic shell and subsequently in the opposite direction through the cavities to intersect the rotor in a cylindrical region located between the cylindrical bands. An electrical circuit couples a utilization device to the rotor. Another embodiment of the invention uses a magnetic mirror to replace one of the permanent magnets. Still other embodiments teach the use of a plurality of toroidal stators mounted in tandem about a common rotor. The machine may be used as a homopolar generator or a homopolar motor.

Abstract: In a method of encoding and decoding informational data for transmission to a storage medium (32), a group G of physical blocks written to the storage medium includes both user data information blocks and auxiliary error correction blocks (70415). Each block (Br,c) included in the group G belongs both to a row r and a column c. Informational data is formatted into preselected bit positions of the user data information blocks. Values for bit positions in the auxiliary error correction blocks (70415) are generated by performing an exclusive OR operation upon values in corresponding bit positions in a subgroup of strategically selected user data blocks. By strategically selecting the user data blocks to be included in the subgroup, the method facilitates recovery of entire blocks, and even rows or columns of blocks.

Abstract: A belt grill or belt cooking apparatus, of the general type previously known for rapidly cooking meat, grilled sandwiches, etc. in a travelling path through the apparatus, has improvements enabling the belt cooking grill to impart grill stripes or grill pat-terns on the product as it is cooked. In one embodiment the improved belt cooking apparatus has upper and lower heat platens (34, 36) with ridges or other types of embossings (46), with the moving belts (12, 14) being formed of a flexible material capable of good heat transfer and good wear resistance at elevated temperatures. The ridges or embossings (46) press the belt into the food product (32), causing greater heat transfer at the ridges than between them, and thus forming a series of grill stripes on the pro-duct while the product is also cooked. In another embodiment, the belts (80, 82) are formed of stainless steel, with corrugations, embossings or ridges (84, 88) which press directly against the moving food product as it is cooked, to effect grill stripes due to greater heat transfer along the lines of pressure.
