Title: Continuously-operating press
Inventor: BIELFELDT FRIEDRICH BERND
IPC: B30B5/06
Filed: 1991-02-25
Granted: 1998-06-02
Abstract: The invention relates to a continuously-operating press suitable for producing particle board, fibreboard, plastic sheets, plywood sheets or similar products.  The press has flexible endless steel bands which circulate about a press bed and a press top over drive rollers and deflection rollers and which serve to transmit pressing force to and a material to be pressed and to pull the material through a press gap between the press bed and the press top.  The steel bands are supported on the press bed and the press top by means of roller rods whose axes run transversely to the direction of movement of said steel bands.  The roller rods extend along heating plates attached to the press bed and the press top. Contact plates are removably and reversibly attached over the heating plates and the roller rods contact the contact plates. The contact plates generally have a thickness of between 7 and 23 mm, a Brinell hardness of 250 or more and finely ground surfaces.  The contact plates can be reversed for prolonged operational life and are easier to harden than the heating plates to which they are attached.
Patent CA-2040346-C (CA)
Inventor: VILLAMAGNA FORTUNATO
IPC: C06B23/00
Filed: 1991-04-12
Granted: 2001-06-12
Abstract: A sensitized explosive composition, and a method of production therefor, wherein the composition is sensitized by the addition of a gas void-containing, gas-in-liquid foam to a base explosive composition. The foam is produced in water or in a non-aqueous liquid carrier and is, preferably, stabilized by the addition of viscosity control and foaming agents. The explosive composition may be, for example, a water-in-oil emulsion explosive or an oil-in-water slurry explosive. The sensitized explosives thus produced are manufactured by a method having improved safety, greater low temperature manufacturing flexibility, and are more economical than microballoon gas void-containing explosives of the prior art.
Patent CA-2040472-C (CA)
Inventor: AMENDOLA ANGEL
IPC: B44C1/14
Filed: 1991-04-15
Granted: 2001-04-03
Abstract: A continuous sheet 27 of metal leaf advanced at a constant rate is moved at variable velocity through a rotary die stamper 6, 7 such that between stamps the metal leaf moves at a velocity which is slower than the velocity of a substrate web 28; but just prior to stamping the metal leaf is accelerated by contact between the metal leaf sheet and a raised die 5 rotating at the velocity of the substrate web so that when the stamp occurs the metal leaf sheet is travelling at a velocity substantially equal to the velocity of the substrate web. Varying the velocity of the metal leaf sheet has the effect of minimizing the distance the metal leaf sheet travels between stamps which conserves consumption of the metal leaf sheet. Separate means for accelerating the leaf sheet prior to stamping and decelerating the leaf sheet after stamping may also be provided.

Title: Disposable apparatus and method for infusing a material into a closed loop system
Inventor: COOPER B WILLIAM
IPC: F25B45/00
Filed: 1992-08-06
Granted: 1997-04-01
Abstract: A method and apparatus for infusing an atomized liquid material into an operating, pressurized closed-loop system.    The  method  uses  an  atomizing  mist  infuser comprising a pre-filled liquid filled disposable capsule (12) having a sealable inlet (14) sealed by an inlet seal (54) and a sealable outlet (16) sealed by an outlet seal (52).    The  disposable  capsule  has  a  reservoir  (18) containing a predetermined amount and concentration of liquid to be infused into the system.  The capsule inlet and outlet are in open communication with the capsule reservoir.  The capsule outlet is connected to the closed-loop system, and an externally available high pressure system carrier fluid supply (30-37) is connected to the capsule inlet to form a high pressure mixture comprising the  liquid material  and the  system carrier  fluid.  A selectively regulated amount of the high pressure mixture is infused as a mist into said closed-loop system.  The capsule sealable outlet means is constructed and arranged to substantially prevent the liquid material held in the capsule reservoir from flowing through the outlet means when the outlet means is unsealed and when the liquid material is subjected to normal gravitational forces, and to atomize the liquid material held in the reservoirs as the liquid material is forced, under pressure, through the outlet means when the outlet means is unsealed.
