Patent CA-1280567-C (CA)
Title: Cleaning flowing viscous material with laterally moving screen adjoining a variable space
Inventor: BRITCHI LUCIAN
IPC: B29C48/08
Filed: 1986-10-02
Granted: 1991-02-26
Abstract: ABSTRACT The invention is concerned with a method and apparatus for cleaning viscous materials, wherein the viscous materials are passed in the molten condition under pressure through a movable strip-shaped screen having an upstream face which retains impurities. The pressure of the viscous material against the upstream face of the strip-shaped screen is reduced when the latter is obstructed by the impurities it retains. The sealing pressure between the strip-shaped screen and a first chamber which feeds the molten material through the strip-shaped screen and a second chamber which receives the filtered molten material is temporarily eliminated, and the strip-shaped screen is moved crossways with respect to the direction of flow of the viscous material to replace a soiled area of the screen by a clean area and then it is immobilized. The first chamber, screen and second chamber are resealed together, the molten material upstream of the screen being simultaneously repressurized, and filtering of the material through the strip-shaped screen is continued. The reduction of the pressure of the viscous material is achieved by increasing the original volume of the first chamber supplying the molten material to the strip-shaped screen, and repressurization of the viscous material is accomplished by restoring the first chamber to its original volume.

Abstract: ABSTRACT OF THE DISCLOSURE         A socket adapter for use with a broom block, the socket adapter for receiving a threaded handle such that the release torque required to remove the handle is aggrandized, i.e. greater than the application torque required to attach the handle.  The socket adapter comprises a tube having an annular lip for abutting against a corresponding lip adjacent the threads of the handle and at least one thread on the tube. The thread begins a predetermined distance below the annular lip such that an expansion space is formed above the thread to provide a space into which the handle thread material may expand.  Upon tightening the handle in the socket adapter with a predetermined amount of attachment torque, the handle material will expand into the expansion space and create an attachment between the handle and the socket requiring a release torque greater than the attachment torque to remove the handle.

Inventor: ALVI ZIA R
IPC: B21J15/16
Filed: 1987-02-09
Granted: 1991-08-20
Abstract: P.309 ABSTRACT            A headed steel pin (10) for a multi-grip fastener of the pin and swageable collar (12) type has a homogeneous microstructure, and consists substantially entirely of sorbitic tempered martensite.          Suitable coarse-grained medium carbon steel is shaped to form a headed pin (10) having a plurality of identical, regularly spaced, annular, combination grooves (22) each able to function alternatively as a locking groove, a pulling groove, or a breaker groove.  The shaped pin (10) is heat treated, the steel being rendered homogeneously martensitic and then tempered at a temperature approaching as closely as practicable to the lower critical temperature of the steel, to convert the martensitic steel entirely to sorbite.          The finished pin (10) has a suitable balance of brittleness, toughness, ductility and impact strength, and tends to break cleanly and reliably at a selected one of the combination grooves (22) when the fastener is installed in a workpiece (60, 62).

Title: Process for the granulating of sulphur and a sulphur granulator
Inventor: GARCIA ROBERTO
IPC: B29B9/00
Filed: 1987-09-11
Granted: 1993-03-23
Abstract: ABSTRACT OF THE DISCLOSURE Sulphur is obtained to the desired granulation and at the same time cooled by means of a directed hollow cylindrical jet of melted sulphur, on either side of which, i.e. both inside and outside the cylinder of molten sulphur, there are jets of cold water, the three jets directed onto a disk which disk is able to turn freely. The jets of water and sulphur strike the disk between the middle of the disk and its outer edge and make it turn, while at the same time the sulphur hardens into granules. The turning spins the granules off the disk. The fact that there are two jets of water leads to a better particle size of the sulphur and, because there is a better contact between the water and the sulphur, prevents any hardening of the sulphur upon the disk.

Title: Peak power shaving apparatus and method
Inventor: ALENDUFF PHILLIP D
IPC: H02J3/38
Filed: 1987-12-03
Granted: 1992-10-06
Abstract: Abstract of the Disclosure Electrical Utility Peak Shaving Apparatus and Method Utility charges associated with peak electrical power demands constitute an increasing portion of utility bills associated with large commercial consumers of electricity.  The instant invention provides an apparatus for reducing the peak electrical demand of a predetermined user operational unit from an electrical power distribution network by controllably operating at least one secondary electrical generator associated with the operational unit in parallel with the utility power distribution network.  The secondary electrical generator includes a switch for connecting the generator in parallel with the utility network in response to receiving a transfer command signal.  A transducer senses the actual peak power demand of the operational unit from the utility network and produces a demand signal having a value responsive to the sensed actual peak power demand.  A memory element controllably stores a plurality of control parameters including a demand setpoint value. A logic device controllably produces the transfer command signal and connects the secondary electrical generator in parallel with the utility distribution network in response to the value of the demand signal exceeding the value of the demand setpoint.  The logic device controls the secondary electrical generator to produce only the amount of power necessary to maintain the demand signal at or below the demand setpoint value.
