Patent CA-2037308-A1 (CA)
Inventor: KOENIG ROLF
IPC: B02C13/28
Filed: 1991-02-28
Abstract: The invention relates to a rotor for impact or hammer mills, whose rotor discs 1 are made of cast steel and have widened roots 3 which according to the invention are welded to one another at their outer edges. Before the welding process, the rotor discs are joined centred by means of fitted bolts 10 provided in the roots 3. The outer edges of the rotor discs 1 remain - at least initially - unconnected to one another so that the roots 3 can be preferably welded to one another automatically by means of annular welding seams 9. <IMAGE>
Patent CA-2038508-A1 (CA)
Inventor: STRAUB IMMANUEL
IPC: F16L17/04
Filed: 1991-03-18
Abstract: A pipe coupling has a cylindrical housing which is split in the longitudinal direction and has inwardly bent end walls and a steel insert sheet of analogous design bridging the gap in the housing. With the aid of a closure with tensioning screws, the housing can be constricted in the manner of a pipe clip, such that a sealing sleeve positioned between the housing and a pipe is compressed in the circumferential direction and brought to bear on the pipes to be sealed off. The closure is offset in the circumferential direction with respect to the housing gap, and the end section of the housing projecting through the region of the tensioning screws is overlapped by a slideway anchored on the other end section. By this means, dimensional stability is increased without increasing the wall thickness, or the constrictability of the housing is guaranteed despite an increased wall thickness.

Abstract: GOLF PRACTICE APPARATUS                  Joseph P.Bussiere Richard A. Bussiere Paul L. Bussiere Daniel J. Bussiere Christopher Lindop ABSTRACT The apparatus is comprised of a platform with a teeing mechanism operated by a user.  The user depresses a lever arm that  depresses  a  tee  and that  activates  a  dispensing mechanism that feeds golf balls to the tee in its depressed position.  The mechanism is comprised of a set of levers,  a ratchet and an axle which extends into a reservoir or golf ball dispenser. The reservoir includes a hole leading to a chute that terminates at a vertical tube in which moves a depressible tee. on the axle, within the reservoir, is a flexible rotating disk with a plurality of oval holes. As the disk rotates, balls in the reservoir fall into the holes, and as the holes pass over the hole in the reservoir, the balls fall into the chute and onto the tee. The ratchet coordinates the motion of the flexible disk so that one ball is moved into position over the hole in the reservoir for each depression of the tee.

Title: Gas displacement device for packaging food and non-food products
Inventor: MARANO GERALD A
IPC: B65D5/74
Filed: 1991-10-04
Abstract: A gas displacement device and method for substituting inert gas for ambient air in a gable-top paperboard carton prior to closing of an open top of the carton. The device includes a source of inert gas connected to an outlet, a hood for forming a blanket of inert gas in a predetermined volume of space which communicates with the outlet, the hood having an opening which lies in a substantially horizontal plane, and a conveyor for moving cartons in a direction of displacement so that each open top passes under the opening. The outlet to which the inert gas source is connected is formed in a wall of the hood. A stream of inert gas from the outlet is injected into the headspace of the container when the container is in a first position, but not when the container is in a second position and the blanket of inert gas overlies the open top of the container when the container is in the second position.

Abstract: Pour commander l'actionnement d'un allumeur électrique à fil résistant, il est proposé un dispositif de mise à feu piézo-électrique qui comprend, a l'intérieur d'un boîtier (10), un mécanisme de commande (14), un générateur piézo-électrique (16) et un transformateur électrique (18). L'enfoncement d'un bouton poussoir (24) du mécanisme de commande (14) propulse une masse (36) contre la coiffe (52) du générateur piézo-électrique. Le signal électrique haute tension et de très courte durée ainsi produit est transformé, dans le transformateur (18) en un signal basse tension, dont l'intensité et la durée permettent d'actionner l'allumeur. Dès le relâchement du bouton poussoir (24), un ressort de rappel (46) ramène le mécanisme de commande dans son état initial, de sorte que le dispositif peut être actionné plusieurs milliers de fois sans maintenance.

Abstract: The use of aluminum sulfate to neutralize alkaline solu-tions yields a gelatinous precipitate.  When neutralization of the solution causes other materials to precipitate along with the gel, filtration of the precipitated materials is very difficult because of the gel.

Abstract: ABSTRACT        Relatively thin microdisc cassette cases having a generally rectangular parallelpiped shape and adapted to house therewithin a standardized 3.5-inch flexible magnetic disc, include a pair of opposing planar cassette case halves, and detent members for joining these cassette case halves one to another in face-to-face relationship.  The detent members include a number of registered male and female detents which are sized and configured to as to be in an interference friction fit with one another.  In such a manner, the cassette case halves are securely joined one to another without necessarily employing conventional ultrasonic welding techniques.  However, the cassette case halves may nonetheless be separated upon application of a separatory force of sufficient magnitude.  Preferably, the cassette case halves, and hence the male and female detent members, are unitarily molded from a polyacetal resin.

Abstract: IMPROVED COMPACT DISC PACKAGE                Inventor:  Donald Spector, a citizen of the United States and resident of Union City, N.J.                 ABSTRACT OF THE DISCLOSURE       A package for a compact disc having impressed on one face thereof a sound or video recording (CD or VCD) of a story or other instructive material relating to a particular character such as a sports or entertainment figure, the opposing face of the disc having a printable surface thereon.  The disc is nested in a circular well formed in a rectangular card having a backing sheet adhered thereto, a circular section of whose inner surface is encircled by the well.  Printed on the printable surface of the disc and on the region of the card surrounding this surface is a picture of the character so that a portion of this picture appears on the printable surface, and the remainder on the card.  Printed on the inner surface of the backing sheet in the section encircled by the well is the same portion of the picture.  Hence when the disc is removed from the well, one still sees the entire picture.          The disc-loaded card is inserted in a transparent plastic sleeve having matching dimensions to provide a card-like package which may be manipulated in play activity as well as stored or displayed.  To play the disc in an optical player, the card is removed from the sleeve and the disc withdrawn from the card.

Inventor: ROWE DOUGLAS J
IPC: G01V5/02
Filed: 1992-06-01
Abstract: This invention relates to the field of prospecting to locate mineral deposits particularly gravel and clay deposits. The method of prospecting to locate these mineral deposits includes the steps of traversing an area of the earth's surface and obtaining measurements of gamma radiation corresponding to the presence of uranium, potassium and thorium at spaced points along the traverse .      The data collected are used to determine an area mean value for the gamma radiation measurements obtained. The mineral location is obtained by noting areas within the area traversed in which the variations of the measurements of gamma radiation corresponding to each of uranium, potassium and thorium relating to the respective area mean values are indicative of the particular mineral being located. It has been found that aggregates may be located by looking for areas in which the gamma radiation corresponding to uranium is approximately equal to the area mean value while the measurements corresponding to potassium are low relative to the area mean and the measurements corresponding to thorium are low relative to the are mean. Clay may be located by noting areas in which the measurements corresponding to uranium are relatively high compared to the area mean value, the measurements corresponding to potassium are high relative to the area mean and the measurements of thorium are high relative to the area mean respectively.
