Patent CA-2098340-A1 (CA)
Title: Light-responsive enclosure alarm
Inventor: DRAGAN STEPHEN
IPC: G08B13/14
Filed: 1993-06-14
Abstract: ABSTRACT OF THE DISCLOSURE           The                      device determines  whether a darkened enclosure has been opened by an unauthorized user.  The device does not require that it first be turned on in light  and when placed into a darkened enclosure, has the capacity of informing the authorized user of a possible unauthorized opening. After an unauthorized opening, and audible alarm would be triggered for a predetermined period of time.  Subsequent to the cessation of this audible alarm, the authorized user by viewing the status of a light emitting diode after depressing an on/off switch, can determine whether an unauthorized user has gained access to the enclosure.

Title: Isokinetic separator apparatus
Inventor: WILLIAMS ROBERT M
IPC: B02C13/26
Filed: 1993-06-24
Abstract: ABSTRACT Apparatus for grinding material which may comprise a flow of ground material that contains both desirable fines and undesirable oversize particles in which a separator rotor is equipped with shaped blades that isokinetically separate out the oversized particles and centrifuges such particles out of the path of the flow of ground material and into a path for returning the oversize particles for further grinding.  The centrifuging of the oversize particles reduces the drag in the flow of the ground material into the separator rotor, and that reduces the horsepower needed to establish the movement of the ground material at a rate that improves the efficiency of the apparatus.  A variation of the foregoing develops pressurization of the material in the separator zone so that the oversize ground material is forced to return to be subjected to further grinding under the influence of a differential pressure in the apparatus while the acceptable material is subject to micron sizing in the rotor.  The apparatus further coordinates the operation of the rotor to air moving devices used to move the material through the apparatus.

Filed: 1994-01-06
Abstract: A gyratory crusher includes a bowl assembly with a concave crushing surface and a crusher head of conical shape which extends into the concave portion of the bowl assembly.  A central crusher axis extends centrally through the bowl assembly. The crusher head is mounted with a central head axis at an angular deviation with respect to the central crusher axis to intersect the crusher axis at an apex.   Crushing action is obtained by driving the crusher head to gyrate the angular offset of its central axis about the central crusher axis.   The gyratory crusher has an adjustable stroke of gyration.  Adjustability of the stroke is obtained by controllably varying the amount of angular deviation by which the crusher head gyrates about the central crusher axis.  The amount of angular deviation is controlled by an eccentric support bearing which gyrates a guide shaft of the crusher head about the crusher axis and which is adjustably mounted to move toward and away from the apex of gyration without also changing the position of the crusher head with respect to the apex.

Title: Extendable conveyor without base unit
Inventor: GILMORE PHILLIP J
IPC: B65G67/08
Filed: 1994-06-09
Abstract: An extendable conveyor unit eliminates the necessity of a base unit by supporting the extendable units directly from the warehouse floor with a minimum amount of support structure. The extendable conveyor includes one or more extendable units, a stationary support for supporting the extendable units, and a conveying surface defined on an extended portion of the extendable units. The stationary support supports the extendable units between a fully extended position, wherein the extendable units extend from the support in the direction of the vehicle to be loaded and a fully retracted position in which the extendable units extend from the support in a direction opposite from the direction of the vehicle to be loaded. The conveying surface may be a gravity roller conveyor or it may be an endless belt. When the conveying surface is an endless belt, an elevating unit may be provided with the stationary support in order to elevate the conveying member above the extendable unit at the stationary support to match up with a discharge or receiving conveyor. A cable routing system to the extendable units includes an electrical cable running between the stationary support and an extendable unit over a sheave mounted to another extendable unit with the extendable units extended at a rate that maintains tension on the cable for all extendable positions of the extendable units.

Abstract: ABSTRACT OF THE DISCLOSURE   A beverage cup lid is disclosed that comprises a circular closure panel, circumscribed by a side wall that terminates in a resilient, restricted diameteredge for capturing a brim of a beverage cup, and a frustro-conical skirt connected around the restricted diameter edge for increasing the hoop strength of the edge, and an extended diameter flange circumscribing the free edge of the skirt for further increasing the hoop strength of the restricted diameter edge such that the edge retains the brim with a force of at least 1 pound. The invention is particularly applicable to beverage cup lids formed by a plastic web machine that applies heat to only those areas that are deformed into structural components on the lid (such as the side wall, restricted diameter edge, and skirt), and which consequently results in some, amount of wall thinning in the skirt, and hence some reduction in the hoop strength that the skirt gives to the restricted diameter edge that retains the cup brim. The radial extent of the flange is large enough to increase the hoop strength, and hence retaining force of the restricted diameter edge by between .5 and 1.0 pounds.

Title: Process for producing aromatic hydroxylic compound
Inventor: ARAKI SHINTARO
IPC: C07C37/08
Filed: 1993-11-01
Abstract: ABSTRACT        There is disclosed a process for producing an aromatic hydroxylic compound by acid decomposition of a hydroperoxide having the general formula (I)   (I) wherein Ar represents an aromatic hydrocarbon group having a valence of n; and n represents an integer of 1 or 2, in the presence of an acid catalyst, thereby to provide an aromatic hydroxylic compound having the general formula (II) Ar-(OH)n (II) wherein Ar and n are the same as above defined, characterized in that tetrafluoroboric acid, hexafluorosilicic acid or hexafluorophosphoric acid is used as the acid catalyst. According to this process,  the aromatic hydroxylic compound is obtained in a high yield while the by-production of hydroxyacetone is effectively suppressed.  In paricular, a more effective suppression of by-production of hydroxy-acetone and a higher yield of the target compopund can be achieved by carrying out the acid decomposition reaction in two stages wherein the first stage of the reaction is carried out in the first reactor at a temperature of 50-95°C, the resultant reaction mixture is sent to the second reactor, and the second stage of the reaction is then carried  out in the second reactor at a temperature of 80-120°C.
