Abstract: An optical disk for optical recording and reproducing data has a spiral track and further includes a single index field and a plurality of sectors. The index field includes an index mark that indicates the position at which an optical head of the optical recording and reproducing apparatus retraces a spiral track by jumping a specific portion of the guide track. Each of the sectors has a sector header, which comprises a sector mark located at the start of the sector and an address field including a track address, sector address, and an error detecting and correcting code. The index mark in the field is detected, and the optical head is made to perform a jumping operation in response to the resulting signal, whereby the jumping operation is rendered certain. When there is a failure to read the address fields, the signal produced by detecting the index mark starts a counter which counts the signal produced by detecting a sector mark, for recovering the sector address.

Title: Traeger.
Inventor: JOHNSON RONALD J
IPC: E04G11/48
Filed: 1985-12-24
Granted: 1992-04-16
Abstract: The present invention discloses a new concrete forming system and components therefor, particularly adapted for forming of vaulted ceilings and for use in buildings wherein the floors at the edges thereof have upwardly extending sills and/or wherein the ceilings have been dropped by a similar ledge or sill thereby significantly reducing the clear area through which a truss can be removed. The truss comprises a top chord and a bottom chord interconnected by upright members and diagonal bracing members. A number of adjustable extension legs are associated with the upright members and are telescopically received within an upright member such that a leg extending to the upper side of the truss can overlap with a leg extending to the lower side of the truss, whereby the legs extending above the truss can be adjusted and maintained independent of the legs extending below the truss. In contrast to the prior art practise of having the upper chord of the truss at the lowest level of the ceiling with "packing" thereabove to define and support the concrete forming surface. The present system provides load collecting support beams adjustably secured above the upper chord of the truss by extendable legs whereby the position of the support beam can vary relative to the top chord of the truss. The height of the truss is used to accommodate the extendable legs which position the truss above the floor as well as the extendable legs supporting the load collecting beam, whereby the amount of packing and the time required to initially set up the system for a given building are reduced. Therefore, the present invention relates to improvements in flying forms and components thereof and in particular to a system which is more flexible and adjustable for the forming of vaulted ceilings.

Title: Method and apparatus for the thermal regulation of a liquid moving mass
IPC: C03B7/06
Filed: 1986-08-12
Granted: 1989-11-23
Abstract: The device comprises a three-dimensional grid of thermocouples which are immersed in a fluid, which is moving in a covered channel and has a temperature above that of its environment. Apertures in the sheathing of the channel can be progressively closed by shutters so as to control the cooling of the fluid through an outgoing radiation through the apertures. Burners with a variable intensity are placed within the channel and allow to heat up the fluid in the vicinity of each burner. The position of each shutter and the fuel flow to each burner are commanded severally, based on the values emitted by the ensemable of the thermocouples in order to obtain a homogeneous repartition of the temperature of the fluid, transversally with respect to the channel.

Granted: 1990-03-08
Abstract: The timepiece comprises an oscillator (1), a frequency divider (2), a control circuit (3), a stepping motor (4), a seconds hand (5), a circuit (7) for detecting steps missed by the motor, an up-down counter (15) having a capacity N, and a flip-flop (16). At each missed step the detecting circuit (7) generates a tally pulse (S7) which increments the counter (15). The latter is also decremented by periodic pulses appearing on the B output of the frequency divider (2). When a cell supplying the timepiece is nearly exhausted, the number of steps missed per unit of time is high and the counter (15) is, on balance, incremented. When passing from state N-1 to state N the counter issues on its Qh output a pulse that causes the Q output of the flip-flop (16) to go high. The control circuit (3) produces, in response to this high state of the flip-flop, a signal warning of the imminent end of the cell's life in the form of an irregular motion of the seconds hand (5). Otherwise, when the cell is still good, the number of missed steps is low and the counter (15) is decremented. When passing from state 1 to state 0 the counter issues on its Qb output a pulse that causes the Q output of the flip-flop (16) to go low, thereby stopping the warning signal.
