Patent CA-2530824-A1 (CA)
Inventor: LONGMOORE KENNETH
IPC: B32B27/32
Filed: 2005-12-19
Abstract: A multilayer, heat-sealable film includes at least a first outer layer and a second, heat- sealable inner layer having a first surface adhered to the outer layer and a second, opposed surface adapted to be heat sealed to and peeled from another surface. The first outer layer comprises a mixture of a polypropylene and a second polymer immiscible in the polypropylene, with the polypropylene constituting over 50% by weight of the mixture. The second layer is free of polybutylene and is formed predominantly of polymers from the group consisting of propylene-ethylene copolymers, ethylene-propylene-butene-1 terpolymers and propylene-butene- 1 copolymers, wherein the propylene in the copolymers and terpolymers constitutes over 50%, by weight, of such copolymers and terpolymers. The films have a peel strength of less than 250 g/in. with peel separation taking place at the interface between the second layer and the first outer layer and/or through the first outer layer. The films of this invention are stand-alone films that can be employed by themselves and/or can be laminated to one or more additional outer films to form a composite film structure.

IPC: B25B23/147
Filed: 2006-02-06
Abstract: The power tool comprises a servomotor, a torque converter and a control assembly that includes a power supply for converting AC to low voltage DC, a drive controller for firstly converting the AC from one phase to three and, secondly, for delivering the latter to the servomotor, a controls apparatus for detecting signals and data to and from the servomotor / torque converter, and also from the drive controller, and a serial communication port for connecting the drive controller to a computer for uploading and downloading data and software/firmware, which computer is used for programming, calibrating and retrieving data incorporated in the memory. The method is based on the fact that the current in the servomotor increases gradually until the converter reaches a preset torque that is programmed to correspond to a specific current that is continuously detected and compared to the current supplied to the servomotor.

Abstract: A method for preparation of smoke extract from wood tar for flavouring and colouring of food products is disclosed. The smoke extract is with the present method produced by means of supercritical extraction of fractions of the wood tar. The extractions solvent, such as carbon dioxide, has very good properties of entraining and resolving the required fractions of the wood tar, and it is relatively simple to separate the resolved components in the retrieving process, as the different components have different solubility at different supercritical and subcritical conditions. Thus, a smoke extract containing less than 10 ppb (parts per billion) of benzo (a) pyrene and less than 20 ppb of benzo (a) athracene may be obtained. In one embodiment, the wood tar is subject to a separation process prior to the supercritical extraction to remove a substantial part of the unwanted components.
