Abstract: A noise blocking earmuff is described, which has a better noise blocking ability and which is more comfortable than prior earmuffs. The earmuff includes a cup-shaped shell (20), a cushion (22) that surrounds the open inner end of the shell and which presses against the head of the wearer, and an inside sound-absorber (26) lying in the shell. The cushion is formed of slow recovery material which has a rebound of no more than about 10 percent, to more comfortably and completely conform the cushion to the area of the wearer's head that the cushion presses against. The inside sound absorber includes a layer (50) of resilient felted foam for blocking higher frequency sounds, and a layer (52) of unfelted foam for blocking lower frequency sounds, to obtain a better overall noise blocking capability.

Abstract: The invention relates to a shuttering element for separating a concreting section into concreting subsections. The shuttering element is of strip-like form and is adapted widthwise to the thickness of the concreting section. It comprises at least a strip-like shuttering board which is formed from a thin-walled, sheet-like material, with the result that, once the concreting section has been cast, the shuttering board can remain between the cast concreting subsections.      The shuttering board preferably has recesses through which reinforcement struts can engage, with the result that the shuttering element according to the invention can be inserted even when reinforcement struts of a reinforcement are to cross the shuttering element.

Patent CA-2296259-C (CA)

IPC: F04B39/00

Granted: 2008-12-30
Abstract: An improved wobble piston and seal assembly for an oil free air compressor. The piston has a seal support surface which is provided with an upwardly directed curve adjacent its perimeter. A flat annular seal is secured to the piston to be supported by the support surface. The curve imparts a limited bend to the seal adjacent the perimeter of the piston. The piston and seal are then inserted into a cylinder which increases the bend to substantially 90°. The region of the bend in the seal adjacent the top of the piston is supported by the curved top to reduce flexing during operation at high air pressures. By preventing a reduction in the bend radius at high air pressures, stress in the seal at the bend is reduced, permitting use of a harder more durable seal material.

Abstract: A process for producing clad pipe comprises forming a hollow body (S10) of base material, bonding a cladding material metallurgically to the base material. (S12) to form a composite body and subsequently extruding the composite body to form a pipe. This process allows the metallurgical bond to be validated using non-destructive methods prior to extrusion. Any areas that arc unbonded will be detected, thereby reducing wastage. Moreover, because the metallurgical bond is achieved prior to extrusion, the cladding thickness is controlled during the extrusion process, avoiding migration of the clad material into the base material by disproportionate amounts.

Patent CA-2312492-C (CA)
Title: Multi-protocol unified file-locking
Inventor: BORR ANDREA
IPC: G06F12/00
Filed: 1998-11-30
Granted: 2006-02-07
Abstract: The invention provides a method and system for correct interoperation of multiple diverse file server or file locking protocols, using a uniform multi-protocol lock management system. A file server determines, before allowing any client device to access data or to obtain a lock, whether that would be inconsistent with existing locks, regardless of originating client device or originating protocol for those existing Locks. A first protocol enforces mandatory file-open and file-locking together with an opportunistic file-locking technique, while a second protocol lacks file-open semantics and provides only for advisory byte-range and file locking. Enforcing file-locking protects file data against corruption by NFS client devices. A CIFS client device, upon opening a file, can obtain an "oplock" (an opportunistic lock). When a client device issues a non-CIFS protocol request for the oplocked file, the file server sends an oplock-break message to the CIFS client device, giving the CIFS client device the opportunity to flush any cached write operations and possibly close the file. Allowing NFS and NLM requests to break oplocks ensures that file data remains available to NFS client devices simultaneously with protecting integrity of that file data. A CIFS client device can obtain a "change-monitoring" lockfor a directory in the file system, so as to be notified by the file server whenever there is a change to that directory. The file server notes changes to the directory by both CIFS and non-CIFS client devices, and notifies those CIFS client devices with "change-monitoring" locks of those changes.</ SDOAB>
