Patent CA-2122069-A1 (CA)
Title: Process for refining oil and fat
Inventor: YAGI TAKASHI
IPC: C12S3/18
Filed: 1994-04-25
Abstract: This invention provides processes for the refining of oil and fat by which phospholipide in the oil and fat to be treated can be decomposed and removed efficiently.      Particularly, it provides a process for the refining of oil and fat which comprises reacting, in an emulsion, the oil and fat with an enzyme having an activity to decompose glycerol-fatty acid ester bonds in glycerophospholipids (e. g., pancreas-derived phospholipase A2); and another process in which the enzyme-treated oil and fat is washed with water or an acidic aqueous solution. Preferably, the acidic aqueous solution to be used in the washing step is a solution of at least one acid selected from the group consisting of citric acid, acetic acid, phosphoric acid and salts thereof. Also, it is preferred that the emulsified condition is formed using 30 weight parts or more of water per 100 weight parts of the oil and fat.      Since oil and fat can be purified without employing the conventional alkali refining step, generation of washing waste water and industrial waste can be reduced. In addition, the recovery yield of oil is improved because loss of neutral oil and fist due to their inclusion in these wastes does not occur in the inventive process.

Title: Remote temperature control system
Inventor: MCNAIR HENRY P
IPC: G05D23/19
Filed: 1994-05-20
Abstract: A boiler control system includes a room temperature sensor 10 which  utilises  radio  transmission  to  send  temperature information via antenna 11 to receiver 15 via antenna 16.  The receiver will provide an output to a control unit 18 to cause actuation of the boiler 19 for example if the room temperature falls below a preset value.  The temperature selected can be varied by means of up/down keys 13/14 on the sensor 10.          Temperature information can be displayed by means of display 12.   Unique coding identifies the transmitting sensor and transmission can be sequenced on a number of frequencies to reduce the risk of reception failure.  Additional temperature sensors including a hand held unit each with a unique identity code can be used and transmission time is varied to avoid coincident transmission from the sensors.  Telephone linkage for a number of devices can be provided.

Abstract: An adaptor (1) can be releasably connected to a fixed plug portion (13 or 21). The fixed plug portion is, with that, for example a component in a measuring device for taking measurements on differing optical fibres. The adaptor is provided with a sleeve (3) in which various transferable plug portions can be temporarily inserted. The sleeve has an axially parallel slot (6) for accommodating a rotational security device on an initial category of fixed plug portions (21). Additionally, the sleeve also has at least one further recess (4, 4, 5) on its outer casing for accommodation of the rotational security device (19, 19', 20) of a second category of fixed plug portions (13). In this way, an interface between adaptor (1) and fixed plug portion (13, 21) is created, which indeed enables combination with an adaptor equipped in the same way, although an adaptor without an additional recess is only able to be placed on one of the two categories.

Title: Pseudo-adenovirus vectors
Inventor: GREGORY RICHARD J
IPC: A61K48/00
Filed: 1993-12-02
Abstract: Gene Therapy vectors, which are especially useful for cystic fibrosis, and methods for using the vectors are disclosed.  In preferred embodiments, the vectors are adenovirus-based.  Advantages of adenovirus-based vectors for gene therapy are that they appear to be relatively safe and can be manipulated to encode the desired gene product and at the same time are inactivated in terms of their ability to replicate in a normal lytic viral life cycle. Additionally, adenovirus has a natural tropism for airway epithelia.  Therefore, adenovirus-based vectors are particularly preferred for respiratory gene therapy applications such as gene therapy for cystic fibrosis.  In one embodiment, the adenovirus-based gene therapy vector comprises an adenovirus 2 serotype genome in which the E1a and E1b regions of the genome, which are involved in early stages of viral replication have been deleted and replaced by genetic material of interest (e.g., DNA encoding the cystic fibrosis transmembrane regulator protein). In another embodiment, the adenovirus-based therapy vector is a pseudo-adenovirus (PAV). PAVs contain no potentially harmful viral genes, have a theoretical capacity for foreign material of nearly 36 kb, may be produced in reasonably high titers and maintain the tropism of the parent adenovirus for dividing and non-dividing human target cell types.

Patent CA-2151952-A1 (CA)
Inventor: KIEFFER JOSEPH W
IPC: B05B7/12
Filed: 1993-12-13
Abstract: A trigger (20) for opening a valve (50) against fluid pressure has two alternate pivot pins (122, 124). The first pivot point (124) has a relatively higher mechanical advantage to make it easier to push the valve against the fluid pressure. The second pivot point (122) has a relatively lower mechanical adavantage to increase the distance travelled by the valve in response to further movement of the trigger to make it easier to control the flow of the fluid pass the valve. The trigger thereby reduces the force required to open the valve without decreasing the range of motion of the valve.

Inventor: MALEK CHARLES JOHN
IPC: H04B1/713
Filed: 1995-09-12
Abstract: A method and apparatus increases spectrum efficiency in a wireless communication system having base stations which may be positioned to operate within range of one another. The method and apparatus eliminates the requirement for a base station to periodically transmit to maintain synchronization with an associated handset (504). The handset effectively assumes the role of a base station when making a call (508).      The handset will synchronize with other handset traffic or another base station which is within range (506). The handset will then page the base station (510). Eliminating the requirement that the base station repeatedly transmit a signal to maintain sync with a handset significantly increases the available spectrum allocation for providing communication.      Reversing the role of a handset also enables handset-to-handset communication independent of the base station (808).
