Title: Method and device for nondestructively, magnetically inspecting elongated objects for structural faults
Inventor: WEISCHEDEL HERBERT R
IPC: G01N27/90
Filed: 1994-04-29
Abstract: A magnetic inspection device for detecting structural faults in elongated magnetically permeable objects has two opposite magnetic poles, at least one pole being an end pole, that induce a first magnetic flux axially in a first section of an object between the poles, and an oppositely directed magnetic flux in another section adjacent the end pole. As the device and object move relative to one another, eddy currents induced in the object by the changing longitudinal fluxes at the end pole are detected to locate structural faults in the object.

Title: Diagnostic test and kit for disease or disorders in the digestive system
Inventor: FAGERHOL MAGNE K
IPC: G01N33/574
Filed: 1994-05-18
Abstract: ABSTRACT OF THE DISCLOSURE         A new diagnostic test and kit for diseases or disorders in the digestive system.            This study describes method for extraction and quantification of calprotectin (L1 protein) in feces by enzyme immunoassay. This  protein  is  a  prominent  antimicrobial  component  of neutrophils, monocytes, macrophages and squamous epithelia. Calprotectin was stable in feces during storage for seven days at room temperature. Fecal calprotectin quantitated in a five gram sample taken from a 24 hours feces collection gave a  reliable  estimate  of  calprotectin  found  in  the  pooled collection. The assay had a within assay precision (=CV) of 1,9 % and a between assay precision of 14,8 %. The following mean fecal calprotectin levels were found: Healthy subjects (n=33)  3095  µg/l,  hospital  controls  (n=40):  14637  µg/l, patients with inflammatory bowel disease (Crohn's disease and ulcerative  colitis),  (n=28)  40850  µg/l.  The  differences between the means are highly significant. All patients with IBD and  ten out  of eleven patients with gastrointestinal carcinomas  had  calprotectin  level  above  the  suggested reference  limit  of  9000  µg/l.  Determination  of  fecal calprotectin is an important routine parameter for monitoring IBD and gastrointestinal cancer.

Title: Spring tooth harrow
Inventor: GATES MICHAEL B
IPC: A01B73/04
Filed: 1994-08-02
Abstract: A spring tooth harrow comprising an elongated tool bar having a  plurality  of  harrow  sections  cured  thereto  by  adjustable mounting brackets to enable the harrow section to be raised or lowered  with  respect  to  the  draw  bar.

The pipes may be rotatably moved in unison to change the angle of attack of the spring teeth or the forwardmost pipe may be independently rotated with respect to  the  remaining  pipes  so  that  the  angle  of  attack of  the forwardmost  spring  teeth  may  be  varied  with  respect  to  the trailing spring teeth.
Patent CA-2131672-A1 (CA)
Title: Linear scanning using a single illumination and scanning optic station
Inventor: PRAKASH RAVINDER
IPC: G02B26/10
Filed: 1994-09-08
Abstract: An optical scanning station is disclosed which utilizes light bending apparatus such as mirrors or optical wedges to gather and redirect some of the illumination radiating from the object. The gathering of the light occurs off-axis from the lens and the redirection of the light to the lens causes an off-axis angle between the light beam and the lens axis, thereby resulting in multiple images which are spaced apart from each other when focused on an image plane. The multiple images may be split apart and directed to separate image planes by use of front surface mirrors making the images then available for individual capture by charge couple devices or other similar image capture apparatus.  Alternatively,  the outboard images may be redirected, again by mirrors, to be focused coincident to the on-axis image, thereby increasing the illumination level at the image plane well in excess of that obtainable with only a single image of the object being focused at the image plane. The primary advantage of these devices is either to permit separate images to be presented on separate  image  planes  without  the  subtractive  losses occasioned by use of subtractive beam splitters or to combine the multiple images to raise the illumination level of a single image at the image plane, thereby permitting the use of slower lenses or reduced illumination level at the object.

Title: Composite cylinder for use in aircraft hydraulic actuator
Inventor: CHING FRED Y
IPC: F16J10/02
Filed: 1992-10-13
Abstract: A composite cylinder constructed from a cylindrical liner (12) having an outer surface (18) which is dome shaped adjacent each end. A plurality of layers (30) of resin impregnated carbon filaments are wound on the outer surface (18) of the liner (19) and over the dome shaped portions. Preferably the filaments are helically wound and are wound at an angle with respect to the access of the cylindrical liner (12) such that radial stress as applied during operation will not tend to displace the filaments wound over the dome shaped portions of the liner (12).

Title: Process and device for preparing film strips for subsequent orders
Inventor: KUNZ JUERG
IPC: G03D15/00
Filed: 1994-11-03
Abstract: PROCESS AND DEVICE FOR PREPARING FILM STRIPS FOR SUBSEQUENT ORDERS            Abstract Process for preparing film strips for subsequent orders, the film strips belonging to a customer order. Each film strip includes a number of numbered masters which are fed into a preparation station. There, they are glued to a carrier belt and coiled into a film roll, which can be used at subsequent processing stations. Customer-specific order data regarding the desired number of copies of specific masters and, where applicable, the desired copy format, are entered via an input unit in the preparation station and stored onto a carrier medium which is compatible with the subsequent processing stations. In the process, the customer-specific order data are entered before the film strips are fed in. The fed-in film strips are automatically checked, before gluing to the carrier belt, for their position parallel to the conveyance direction and for the number order of the masters on the respective film strip, and by comparing with the customer-specific order data entered, it is checked whether the fed-in film strip is required for processing the customer order. If a film strip is improperly positioned or if a film strip is superfluous for processing the order, the operating personnel's attention is automatically drawn to the respective error, or the concerned firlm strip is automatically expelled before being glued to the carrier belt. A device according to the invention has an insertion area for the film strips which is equipped with at least one photoelectric sensor before a pair of draw-in rollers and which has, following the pair of draw-in rollers, a photoelectric scanner for the master numbers.

Title: Public-Key Cryptographic Apparatus Handling Ciphertext by Public-Key
Inventor: SHIMADA MICHIO
IPC: G09C1/00
Filed: 1995-02-07
Abstract: The invention provides a public-key cryptographic apparatus which does not leak information regarding a plaintext and can prevent an increase in block length.          A quadratic residue calculation circuit calculates a residue when the square of the lower n-1 bits of the plaintext of n bits is divided by public-key, and an exclusive OR circuit calculates an exclusive OR of the least significant bit of a result of the calculation and the most significant bit of the plaintext.  Then, public-key encipherment such as the RSA cryptosystem or a modified Rabin cryptosystem is performed twice repetitively for totaling n bits of the output of exclusive OR circuit and the lower n-1 bits of plaintext by public-key enciphering circuits so as to make it impossible to estimate the most significant bit of the plaintext from the ciphertext.
