Abstract: The invention concerns a crusher comprising a ring-shaped track with horizontal axis (14), a roller (16) rolling on said track, means for pressing the roller on the track and means (18) for displacing the material from one track edge to the other so that it passes several times under the roller before it is evacuated. In order to improve the efficacy of the roller and the distribution of mechanical stresses in the roller and the track, the track (14) and the roller (16) are so designed that the space between them decreases from the track (14) edge on the side supplying the material to be crushed up to a distance from said edge not less than 80 % the track width, and that this space then quickly increases to constitute a decompression zone (19) on the side where the material is evacuated.

Abstract: An injection-moulding unit for an injection-moulding machine has an injectio n motor (E) to activate an electromechanical injection unit (16) for axial movement of the feed screw (12). An electromechanical rotary motor is provided to be able to turn the feed screw independently of the axial movement. The rotary motor (R) and the injection motor (E) work via a first drive element (19) and a drive element (20) coaxial to the first drive element (19 ) to make the feed screw move. To transmit the axial movement to the feed screw (12) by a means of linear movement (16a) of the injection unit (16), there is an axial bearing element (21) directly between the first drive element (19) and the other drive element. The axial bearing element is a force-transmission element, but at the same time has the job of acting as a means of separation to allow the drive elements 19, 20 to rotate independently of one another and, if necessary, at the same time. This is a simple way of permitting compact coupling of the drive elements for dosing and injection on an injection-moulding unit.

Title: Secure mutual network authentication protocol
Inventor: MACKENZIE PHILIP DOUGLAS
IPC: G06F21/44
Filed: 2000-07-06
Granted: 2005-03-01
Abstract: A password-only mutual network authentication protocol and key exchange protocol using a public key encryption scheme in which a server generates a public key / secret key pair and transmits the public key to a client. The client determines whether the public key was chosen in an acceptable manner, and if so, continues with the protocol. Otherwise, the client rejects authentication. If the protocol is continued, in one embodiment the client generates a parameter p as a function of the public key and a password (or, in an alternate embodiment, as a function of the public key and a function of a password). If the public key space mapping function F PK applied to p, F  PK(p), is an element of the public key message space, then the protocol continues. If F  PK(p) is not an element of the public key message space, then the client determines to reject authentication, but continues with the protocol so that the server does not gain any information about the password. If the client determines to reject authentication, it will terminate the protocol at a later step at which time the termination of the protocol cannot leak any sensitive information. If both the client and the server accept authentication, then session keys are generated for subsequent secure communication between the client and server. Specific embodiments are disclosed in which RSA is used as the public key encryption scheme.

Title: Method of reducing axial beam focusing
Inventor: BERGSTROM JAN OLOF
IPC: H05H13/00
Filed: 1999-09-28
Granted: 2010-02-16
Abstract: A method is disclosed for minimising the diameter of the magnet poles of a cyclotron system for production of radioactive tracers. The method selects an operation mode having v z defined below the critical resonance value of v z= 1/2 and chooses a valley technique having shallow valleys by selecting a first magnet pole parameter defining a valley gap accepting a narrow spaced RF electrode system and size facilitating a vacuum conductance necessary for obtaining a low enough pressure. The method then defines a second magnet pole parameter by setting a sector gap size. The magnetic azimuthal field shape is transformed from being "square-wave"-shaped to becoming approximately sinusoidal by increasing the magnetising field. Then an average magnetic field is calculated from the increased magnetising field and the first and second magnet pole parameter. A pole diameter can then be established to obtain a most compact design of the electromagnet for a cyclotron system. A cyclotron system in accordance with the method is also disclosed.

Abstract: A fuel-fired, forced draft air heating furnace is provided with a draft inducer fan structure which substantially reduces the operational noise of the furnace. The draft inducer fan is disposed within a sealed burner vestibule area of the furnace and is provided with an auxiliary fan blade structure mounted on its drive shaft in a spaced relationship with its main fan impeller. The auxiliary fan blade structure and the fan motor are disposed within an open-ended air transfer duct structure coupled to an air inlet opening in an exterior wall portion of the vestibule. During operation of the draft inducer fan, combustion air is drawn inwardly through the transfer duct structure, across the inducer fan motor, and into the vestibule for supply to the furnace burner section. The use of the transfer duct structure and auxiliary fan blade structure serves to cool the fan motor, preheat the combustion air, and reduce the overall operational noise of the furnace. A baffle plate member is placed in a shielding relationship with the burner structure to inhibit burner flame flickering that might otherwise be caused by combustion air impingement with the burner flames.

Abstract: The present invention relates to a tooth whitening strip of material having a shape adapted to fit a user's teeth. Each user has four front teeth, two canine teeth and additional back teeth, such as molars. Each tooth has a front side, a tip, and a back side. The strip of material is of a shape so that the strip will substantially cover the front side of at least the user's front four teeth and two canine teeth. The front sides of additional teeth may be covered. The tooth whitening strip will then fold over the tips and onto the back side of one or more of the front four teeth. However, the strip of material will not cover the tips of the two canine teeth. The strip of material may be of any shape that allows for the canines to protrude. Possible shapes include substantially trapezoidal with or without stair stepped sides or notches, and rectangular with notches, stair stepped sides, or recesses.

Abstract: A papermaking belt comprises a reinforcing element and a resinous framework joined together. The resinous framework is formed by a plurality of resinous beads which mutually contact or cross-over. Superknuckles extending outwardly from the reinforcing element are formed at points of contact. A  preferred continuous process for making the belt comprises extruding, in a pre-selected pattern, a plurality of beads of a resinous material onto the forming surface thereby forming the resinous framework thereon, joining the resinous framework and the reinforcing element together, and then solidifying the resinous framework. The resinous material may comprise at least two chemically-active materials capable of cross-linking upon contact. The present invention provides a novel process and an apparatus for making a papermaking belt by extruding a fluid resinous material onto the reinforcing element according to a desired predetermined pattern and then solidifying the patterned resinous material.
