Patent CA-2071598-A1 (CA)
Inventor: EDA AKIRA
IPC: H01S3/23
Filed: 1992-06-18
Abstract: At least one convex arcuate face (or concave arcuate face) is formed by photolithography on a photoresist layer formed on a surface of an optical device constituted from an optical material, and the surface of the optical device and the photoresist film are etched continuously or stepwise to form on the surface of the optical device at least one convex arcuate face (or concave arcuate face) similar to the convex arcuate face (or concave arcuate face) of the photoresist film.  In case the optical material is polished into a mirror face, a photoresist film is formed on the polished face, and the polished face and the photoresist film are etched uniformly.  An optical device obtained in this manner is used for a laser oscillator, a monolithic laser system, a non-linear optical device, a microlens, a ring laser and so forth.          On the other hand, a plurality of reflecting portions are provided on each of a pair of opposing faces of a light transmitting optical material, and a reflecting portion of at least one of the faces is formed from a convex arcuate face formed on the surface of the light transmitting optical material.  A zigzag optical path is formed between the reflecting portions of the opposing faces of the light transmitting optical material such that it couples the reflecting portions alternately to each other, thereby to obtain an optical device having a long optical path.  The optical device is employed as a higher harmonic wave converting device for light of a high efficiency for a short wavelength laser apparatus.

Title: Synchronization of vertical phase of video signals in a video system
Inventor: THOMPSON EDWIN S
IPC: H04N5/073
Filed: 1992-07-07
Abstract: A video system in which synchronization of the vertical phase components of a plurality of video signals is carried out by a plurality of reference signals having substantially the same frequency and substantially a fixed relative phase relationship.  Each vertical synchronization signal is locked to one of the reference signals at a phase associated with the measured phase difference between the vertical synchronization signal and a selected one of the reference signals. In this way, all the vertical synchronization signals are brought into phase with one another.

L'enregistrement en continu de données numériques est remplacé par un enregistrement par rafales. Suite à l'enregistrement par rafales des données, chaque rafale forme sur le support d'enregistrement une grappe. Les données sont de préférence enregistrées en utilisant le format standard d'enregistrement sur CD à un débit de 1,411 Mbit/s. Le procédé est utile pour enregistrer et reproduitre des données sur un support d'enregistrement sur lequel on peut ré-enregistrer et qui peut être lu sans contact, tel qu'un disque magnéto-optique (MOD).

Title: Impact Pad with Horizontal Flow Guides
Inventor: SOOFI MADJID
IPC: B22D11/112
Filed: 1992-08-21
Abstract: An impact pad for use in a tundish vessel utilizes outer and inner guides (12,16) which partially surround the region of impact (20) except in the direction of one or more tundish drains (44). Much of the molten iron or steel entering the tundish is directed toward a drain by the inner guide or guides (16).

Title: Supporting element to be used in building constructions
Inventor: LEEUW PETRUS J L DE
IPC: E04G25/06
Filed: 1992-01-27
Abstract: Supporting element for building constructions, comprising an outer tube (3) made of sheet steel, in which an inner tube (1) can be telescoped, the outer tube having ridges (13) intentionally provided by way of de-formation and constituting a guide for the inner tube (1).      As a result, lateral damages such as dents caused during construction operations may be absorbed by the wider portions of the outer tube (3) without impeding the teles-copic capability-of the inner tube (1). For coupling this element, a ring (23) is welded to the outer tube (3) which ring has a widened portion (31) at the location of each ridge (13), so that between the tube and the ring a cavity (33) is created which may accommodate the hooked end (35) of a coupling element (37). This end can be locked in that cavity by means of a lever (39) clamped with its end portion (54) against the bottom of the ring (23) by way of a displacing mechanism (41).

This is achieved using noncontact means. The system comprises a particle size monitoring probe disposed in the exhaust stack. The probe detects and counts particles having sizes within a predetermined size range and provides data indicative thereof. A computer is coupled to the probe and runs a program that computes the the total mass of the particles expelled from an exhaust stack. This information is derived from the data provided by the probe, and particle size, and the total quantity and total mass of the particles monitored in the exhaust stack are provided as output data. The present system and method measures particulates in the size range from (a) 50 microns to 3100 microns, (b) 100 microns to 6200 microns, or (c) 150 microns to 9300 microns. The particulates measured by the system may be water particles, wet paint particles, a solid particles. The present system and method is adapted to determine whether or not particulates are being discharged in an exhaust stack, when they are being discharged, what size and quantity are being discharged, and the total mass of particulates discharged during some time interval.

Abstract: ABSTRACT            Induction  method  for  a  compression-ignition  internal combustion engine.         Using a centrifugation effect,  the fresh air introduced to the working chamber (1) of the engine is prevented from mixing with the combustion gases inten-tionally retained in the latter from one cycle to the next. The means for introducing pressurised fuel (10) are arranged so as to inject the fuel directly into the central zone (G) of the chamber (1) where the concentra-tion of the retained combustion gases and the temperature are thus made maximal, which makes it possible to reduce the ignition delay of the fuel.

Abstract: Peat moss is palletized in bulk compressed form by holding  a  predetermined  quantity  of  peat  moss  stacked vertically  on  a  pallet  to  confine  the  peat  moss  to  a desired,  compressed shape,  the peat  moss having a water-content ranging from about 25 to about 50   weight  %  and a density ranging from about 0.05 to about 0.15 gm/cc on dry basis,  and downwardly compressing the peat moss  directly onto the pallet at a pressure ranging from about 3 to about 5 kg/cm2 so as to form the peat moss into a coherent, shape-retaining body without  substantially altering the water-content and intrinsic properties of the peat moss.  The body of compressed peat moss maintains a structural integrity for a period of time sufficient to permit wrapping thereof. Such a body of compressed peat moss is then wrapped to retain the peat moss in compressed form on the pallet.   The invention enables one to significantly increase the quantity of peat moss per unit of shipment.
