Title: Device for cleaning metal surfaces after they have been worked at high temperatures
Inventor: ALBONI ALESSANDRO
IPC: C25F7/00
Filed: 1996-08-27
Abstract: The device proposed for cleaning metal surfaces consist of pad (12, 34, 91) of insulating material held between a beak-shaped (11, 52, 94) electrode (10, 26, 46) and the metal surface (8) tobe cleaned, plus a low-voltage a.c. power supply (2) which is connected via the other electro-de to the metal (7). A pump supplies the pad with a highly corrosive, high-density, acid solution. The pad consists of a relatively thick hose or tape. The device has slots (36) into which the gases and vapours produced during cleaning are drawn by an extractor fan (40) and then passed through a washing bottle (41) where they are cleaned. The electrode may have various shapes, and it is possible to replace the tip (28, 94, 98). The electrode is preferably designed with bores through which the acid solution can be fed. The main body (97) of the electrode and the replaceable tip (94, 98) may be coated with a la-yer (101, 100) of insulating material which prevents short-cicuits occurring and concentrates the electrolitic action ant the end surface (102) of the electrode. Woven of felt fabric made of plyetheretherketone is preferably used as the insulating material of the pad. The lifetime and working capacity of the device are maximized by using a double-layer pad (92, 93), the inner layer being made of woven fabric (92) and the other layer of felt (93).

Title: Dna vaccination for induction of suppressive t cell response
Inventor: WAISMAN ARI
IPC: A61P37/00
Filed: 1997-02-24
Abstract: A pro-inflammatory T response is specifically prevented by the injection into a recipient of DNA encoding the variable region of a T cell receptor. In response to the vaccination, T cells expressing the variable region produce Th2 cytokines, including IL-4. A  pro-inflammatory T cell response directed to an autoantigen is shown to be suppressed by DNA vaccination. The suppressive vaccination further reduced the inflammatory effect of T cells reactive against epitopes of the autoantigen not recognized by the variable region used for vaccination.

Title: Security label with diffusing identifier medium and method of making same
Inventor: MARFORI WALFREDO M
IPC: G09F3/02
Filed: 1996-08-21
Abstract: A security label (20) with the sheet material (21) having a first major surface. An adhesive layer (26) containing an identifier medium (32) is coated on the first major surface. A barrier medium (22) is selectively applied on an exposed surface of the adhesive layer for at least partially blocking diffusion of the identifier medium from the adhesive layer into a substrate (30). A release liner (28) may be provided that extends substantially over the exposed surface of the adhesive layer. A method of preparing the security label includes applying a barrier medium in the form of an identifier pattern to a low energy surface material.  The low energy surface material is laminated to a security label having an adhesive layer containing an identifier medium. When the low energy surface material is removed from the adhesive layer, the barrier medium substantially transfers to the adhesive layer to block diffusion of the identifier medium into a substrate.
Patent CA-2251515-A1 (CA)
Inventor: CHOI CHRISTOPHER
IPC: G01C15/00
Filed: 1998-11-05
Abstract: This projector level is composed of a bottom plate, a main structure above the bottom plate, a lid on the main structure, a connection plate over the lid, a main structure internal base block hanging freely from the lid with a perpendicular bi-axial universal coupling, a group of laser ray producers situated on the base block, and a battery case holding the battery that supplies power to the laser producers. On the base block, there is a semitransparent projection lens. In front of the semitransparent projection lens , there is an expansion lens. Parallel laser rays go through, and are reflected by, the projection lens. Those rays going through the projection lens proceed through the expansion lens to form a vertical or horizontal line on a surface in front of the projector. Those rays reflected by the projection lens form two opposite dots, one above the projector level and the other below the projector level. These two dots form a plumb line.  Several similar projector levels can be used together, with one situated on the top of the other, and so on. The angles of multiple lines from several projector levels can be adjusted and can be based on the same reference coordinate, which is convenient for construction purposes.

Title: Methods and apparatus for multiple-iteration cmea encryption and decryption for improved security for wireless telephone messages
Inventor: FRANK ROBERT JOHN
IPC: H04L9/06
Filed: 1998-04-14
Abstract: An enhanced CMEA encryption system suitable for use in wireless telephony. A  plaintext message is introduced into the system and subjected to a first iteration of a CMEA process, using a first CMEA key to produce an intermediate ciphertext. The intermediate ciphertext is then subjected to a second iteration of the CMEA process using a second CMEA key to produce a final ciphertext. Additional security is achieved by subjecting the plaintext and intermediate ciphertext to input and output transformations before and after each iteration of the CMEA process. The CMEA iterations may be performed using an improved use of a box function which adds permutations to a message or intermediate crypto-processed data. Decryption is achieved by subjecting a ciphertext message to the reverse order of the steps used for encryption, replacing the input and output transformations by inverse output and inverse input transformations, respectively, as appropriate.
