Patent CA-2156993-C (CA)
Inventor: GRAY JOHN C
IPC: B21D7/022
Filed: 1995-08-25
Granted: 2005-08-16
Abstract: A vertical frame supports an interchangeable mandrel or die which receives the center portion of an elongated metal rod having opposite threaded end portions, and the rod is clamped to the die by a pivotal locking bar secured by a wedge actuated by a hydraulic cylinder. The frame also includes a vertical plate having upper and lower corner blocks connected by a pair of vertical guide rods. The rods support a horizontal carriage cross bar for vertical movement, and the cross bar pivotally supports upper end portions of a pair of arms each formed by rigidly connected parallel spaced plates having aligned straight cam slots. A pair of bending rollers are supported by the lower end portions of the arms, and a hub member extends between the plates of each arm and supports slide blocks which wave within the cam slots. A hydraulic cylinder moves the cross bar vertically to move the arms and bending rollers along converging paths for overbending the rod around the die.      An elongated adjustment screw is rotatably supported by the lower corner blocks and a center block and extends between the plates forming the arms. The screw has appositely threaded portions engaging the hub members to provide for conveniently and precisely adjusting the spacing between the bending rollers for accommodating dies and rods of different sizes and shapes.

Granted: 2008-07-15
Abstract: Method of communication for an intelligent digital, audiovisual playback system. The method for communication between a central server and a computerized jukebox is characterized in that it operates in a conference mode and includes sending, prior to any transaction, a header including the identity of the destination target, the originator identity and the packet size; sending the response of the server as a data packet, each packet from the server being encrypted by the code which identifies the jukebox software. The jukebox receives and then decrypts the data packet. At the same time the packet controls the data received by the cyclic redundancy check method (CRC) and sends an acknowledgement of receipt to the server stating that the information received is accurate. The server can then prepare a new packet addressed to the unit.

Abstract: A process and apparatus for tobacco expansion is employed for expanding tobacco at rapid throughput rates.  The apparatus includes a spool and shell assembly (10) wherein the spool (16) is moveable within the shell (14) between loading (12), impregnating (18), and unloading (20) positions.  In the impregnating position, sealing assemblies (38a-38d) seal the radial clearance between shell (14) and the end members (35, 36) of the spool to provide a pressure vessel for tobacco impregnation.  The sealing assemblies includes at least one elastically deformable sealing ring (28a, 28b) associated with the circumferential exterior of the end member (35, 36).  A pressure applying member (44a, 44b) is operatively associated with an axial end of each of the sealing members to releasably impart axial pressure onto the axial end of the sealing member when the spool is in the treating position to cause radial expansion of the deformable sealing ring (28a, 28b) and thereby accomplish sealing of the spool within the shell.

Abstract: An apparatus for adjusting the level of liquid in a vaporization chamber even if the vaporization chamber is tilted.  The device consists of a flexible bag through which liquid passes via a tube to a float valve and hence to a heated vaporization chamber.  The float valve consists of a cylindrical float housing with a cylindrical float having a closed top surface and an open bottom surface.  The diameter of the float is slightly less than the diameter of the float chamber thereby forming a capillary gap therebetween.  A valve member is situated at the top of the float for controlling the flow of water from the tube through the float housing into a heated vaporization chamber.

Title: Releasable grip facemask for helmet
Inventor: WHITE MICHAEL D
IPC: A42B3/20
Filed: 1996-10-17
Granted: 2008-06-17
Abstract: A facemask (10) for a helmet (5) which is of at least two parts (12, 14) and is split in the middle and resiliently mounted on the sides of the helmet. In accordance with the invention, the facemask will tend to open outwardly thereby increasing the likelihood that an opponent's grip on the facemask will be released. The facemask can be releasably mounted on the helmet so that, if the grip is not released, the portion of the facemask being grasped will then "break away" from the helmet. The force required to open up the two-part facemask is less than the force required to cause one or both parts of the facemask to be detached from the helmet. The present invention can be used with helmets for sports such as football, ice hockey, lacrosse, or other contact/collision sports.

Abstract: A method of encrypting clear payload data to form encrypted payload data uses a block cipher, the block cipher being characterized by a predetermined block length. The method includes a step of parsing (7) and first and second steps of encrypting (8). The step of parsing parses (7) the clear payload data into at least one full clear block. Each full clear block is characterized by the predetermined block length. The residual block is characterized by a residual block length, the residual block length being less than the predetermined block length. The step of parsing further parses (7) the last full clear block into a first part and a second part, the second part being characterized by a length equaling a difference between the predetermined block length and the residual block length.

Title: Method for the compression of recordings of ambient noise, method for the detection of program elements therein, and device therefor
Inventor: BICHSEL MARTIN
IPC: G01H17/00
Filed: 1998-06-22
Granted: 2007-05-22
Abstract: The amount of data produced in the process of recording even short hearing samples by means of a monitor (1) may be considerably reduced by effecting a normalization to a range of values D and a subsequent nonlinear mapping to a second, preferably smaller range of values W. The result may be stored in an electronic memory. Further preferred measures are the spitting of the hearing samples into e.g. 6 signals each of which contains a respective frequency band of the original signal, and the conversion of the original amplitude values into energy variation values with simultaneous low pass filtering. Preferably, all cited processing steps are performed by a signal processor (9). A continuous recording time of up to 14 days by a monitor in the form of a wristwatch can thus be attained with state-of--the-art technology.
