Title: Method and device for performing a flying splice
Inventor: MADRZAK ZYGMUNT
IPC: B65H19/18
Filed: 1995-08-11
Abstract: An unwinding station for fiber webs, particularly paper webs, features a support each for a new web roll (primary paper roll 16) and for a previous web roll (secondary paper roll) as well as a system for splicing the web leader of the primary paper roll on the fly to the web end of the secondary paper roll.  This system allows the so-called flying splice.  A drive unit (M) operating selectively as a motor or brake is coupled to the primary paper roll (16).  An RPM control (24) or a web draw control (25) is coupled selectively to a control (20) of the drive unit (M) using a switching system (34).  An additional drive (M') operating exclusively as a motor is coupled to the primary paper roll (16), and at that, during the period of time between the activation of the drive unit (M) and splicing the web on the fly, independent of the drive unit (M).

Patent CA-2161635-A1 (CA)
Inventor: REYNOLDS ANDREW JOHN
IPC: B65D79/00
Filed: 1994-03-31
Abstract: Method and apparatus is described for removing oxygen from a can (12) and frothy head inducing capsule (10) of a lightweight two piece can beverage pack storing alcoholic beverage under gaseous pressure. The method involves evacuating the can and the capsule combination and purging with an inert gas such as Nitrogen and retaining the purged condition of the capsule and of the can by filling the can with water. Just before the can is to be filled the can is inverted to pour the water away and is washed in a conventional manner and re-inverted ready for filling. The method may be by marshalling cans on a conveyor and purging a large number of cans simultaneously in a batch first of all to the evacuation, then the purging step and then the water filling step. Two batch purging units (94, 96) may be provided and operated out of synchronism to provide a continuous supply of purged cans partly filled with water ready for feeding to the can washing (56) and filling (64) facility. Alternative apparatus involves injecting Nitrogen gas in liquid or gaseous form into the capsule before or after it is inserted into the can and plugging the hole made by the filling device (24) so as to retain the gas charge within the capsule.

Title: Indicator device responsive to axial force
Inventor: GARBY GAGE
IPC: A61M15/00
Filed: 1994-09-22
Abstract: A device to indicate the application of a non-rotative force, having particular utility in recording the dispensing of a push-down activated aerosol medication dispenser. A non-rotative force on an outer cover (20) is translated into a rotation of an indicator wheel (50) relative to the outer cover by a set of flexible pawls (80) engaged with a set of teeth (58). The pawls depress and thereby extend circumferentially when the applied force flexes them to effect a rotation of the teeth. Suitable means indicate the relative rotation of the teeth such as a window (26) in the outer cover through which are visible indicia on the indicator wheel. The device may also include means to resist its operation by a child.

Inventor: WAGNER JOHN R
IPC: A24B3/18
Filed: 1996-06-20
Abstract: A tobacco expansion method is provided whereby cured tobacco is first moistened with a humectant solution, as is conventional in the industry, to increase the resident liquids thereof. Next, the prepared tobacco in shredded form is placed in a sealed chamber and the chamber evacuated to vaporize a portion of the resident liquids. Next, ethyl alcohol vapor is allowed to enter the pressure chamber below 70 mm (Hg) absolute to prevent a water-ethyl alcohol azeotrope from forming. Thereafter, a hydrocarbon vapor, such as n-pentane vapor, is directed into the chamber and the pressure restored to atmospheric. The n-pentane vapor diffuses into the cellular structure of the tobacco with the assistance of the ethyl alcohol, whereafter the tobacco is heated and the n-pentane and ethyl alcohol acts as a propellant to expand the tobacco.

Abstract: Waterborne acoustic signals are received and processed into electrical driver signals to energize a transducer  (30) held in selectively  controllable vibration-transmitting engagement  with a tooth (29) of an underwater  diver.  The transducer (30) converts the electrical signals into low amplitude sound-associated  vibrations imparted to the tooth (29), through the jawbone and skull to the cochlea for processing into electrical signals carried to the brain and perceived as intelligible sound.  The addition  of  conventional broadcast  permits two-way underwater communication.  The transducer (30) can be labially or occlusively  mounted, preferably against an upper or maxillary tooth (29) and the force of engagement  between the transducer (30) and the tooth (29) is at least partially controlled by the diver to optimize  communication characteristics.

IPC: E04G21/14
Filed: 1996-01-04
Abstract: A support member for a concrete structure comprises a T-shaped (10) insert defining a T-shaped internal volume (14).   A nut (20) is inserted in the transverse portion of the internal volume and end caps (24) are placed over the ends of the insert to fully seal enclose the internal volume. The insert is then placed within a form for a concrete structure such that the base surface of the T-shaped insert will be coplanar with a surface of the concrete after the concrete has been poured into the form and set. The base wall (12a) of the insert is then removed, thus exposing the T-shaped volume. The distal end of a bolt (2) can be inserted into the insert and fixed to the nut (20). The proximal end of the bolt extends out of the insert and beyond the surface of the concrete and can be attached to equipment or other structure which is to be supported on the concrete structure. Feet (42) may be provided on the end caps to support the insert away from the surface of the form so that when the concrete is poured and set, the insert will be embedded within the concrete rather than contiguous with the surface of the concrete. Antennae (44) may be provided on the end caps to extend above the base surface of the T-shaped insert so that such antenna will extend above the surface of the concrete so that the insert can be easily located visually.
