Title: Threaded joint for steel tubing including a seal at the threading
Inventor: PLAQUIN BERNARD
IPC: F16L15/04
Filed: 1985-10-08
Abstract: The invention concerns a steel tube threaded joint particularly useful in the petroleum industry of the type in which the male element (3) and female element (1) are combined by threading (2, 4) wherein a portion of the surface of each thread is forcefully applied to the status of screwing to the thread of the outer element. A first element (1) of the joint has a composite structure and has on at least a certain length of its thread a lining of synthetic material whose volume and shape correspond exactly to the volume and shape of the existing clearance of the screwing status between the metal part and composite element (1) and the second element (3) having dimensions at the limit of the machining tolerances which allow the greatest possible clearance in the assembled state of the joint.

Title: Semipermeable nerve guidance channels
Inventor: VALENTINI ROBERT F
IPC: A61B19/00
Filed: 1988-03-29
Abstract: Medical devices and methods employing semipermeable materials, such as acrylic copolymers, polyurethane isocyanate, and other biocompatible semipermeable polymers, are disclosed for use as guidance channels in regenerating nerves. The devices can be formed by tubular semipermeable conduits adapted to receive the ends of a severed or damaged nerve. The tubular conduits define lumens through which axons can regenerate to restore motor and/or sensory functions. The guidance materials are chosen such that they are capable of allowing the diffusion of nutrients and other metabolites to the regenerating nerve site while excluding fibroblasts and other scar-forming cells. In particular, tubular channels which have a smooth inner surface and longitudinally oriented trabeculae result in significantly larger regenerated nerve cables and higher numbers of regenerated myelinated axons.

Title: Shaped,compressed controlled-release unit-dosage forms,and process for their preparation
Inventor: STEMMLE BERTHOLD
IPC: A61K9/20
Filed: 1991-07-01
Abstract: Process for the preparation of shaped, compressed controlled-release unit-dosage forms from a therapeutic active substance exhibiting a self-retarding release that depends on the magnitude of the force used for the compression. The process gives unit-dosage forms for which the release of the active substance is highly uniform, reproducibly identical and largely linear. To achieve this, the active substance and an additive charge that inhibits or compensates for the self-retardation of its release are processed into particles in the first stage of production, so that the preliminary compressed objects made from these particles without any further additives exhibit a rapid release (in comparison with the required controlled release) over the range of the force of compression envisaged for the production of the unit-dosage form in question, after which the particles are compressed in the second stage of production with a release-retarding agent to obtain the unit-dosage forms. The invention also relates to the unit-dosage forms thus obtained.

Patent ZA-929224-B (ZA)
Title: Pipe coupling.
Inventor: STRAUB IMMANUEL
IPC: F16L21/06
Filed: 1992-11-27
Abstract: The pipe coupling has a housing (10) which can be constricted and in which the elastomer sealing collar (32) is arranged which has a C-shaped cross-section and sealing lips (36) extending towards one another. The meandering spring ring (44) which has a U-shaped cross-section and is provided with slots (74) is inserted into the respective annular groove (42) in order to support the sealing lip (36) on the collar web (34). When the housing (10) is constricted, the collar (32) is compressed in the circumferential sense and the sealing lips (36) rest smoothly on the pipe wall (55). At the same time, the spring ring (44) is constricted by the width of the slots (74) being reduced. The sealing lip (36) is supported by the spring ring (44) over a large area and the material of the collar (32) is prevented from flowing into and through the slots (74). The spring limb (68) which projects beyond the sealing lip (36) prevents the annular bead (56) sticking to the collar web (34). This pipe coupling is particularly suitable for use in the case of high operating temperatures and large temperature changes.

Title: Read head with read track width defining layer that planarizes the write gap layer of a write head
Inventor: CHANG HENRY CHINLIN
IPC: G11B5/012
Filed: 1999-11-24
Granted: 2002-12-18
Abstract: A read track width defining layer is employed for defining first and second side edges of a read sensor. The read track width defining layer preferably remains in the head to planarize the read head at first and second hard bias and lead layers so as to overcome a problem of write gap curvature in an accompanying write head. The read track width defining layer is defined by a subtractive process about a bilayer photoresist layer. The subtractive process is selective to the read track width defining layer over a read sensor material layer therebelow. Ion milling is then employed for defining first and second side edges of a read sensor layer employing the read track width defining layer as a mask. First and second hard bias and lead layers are then deposited which make contiguous junctions with the first and second side edges of each of the read sensor and read track width defining layers. The photoresist is then removed and the remainder of the read head is completed.

Title: Process for the isolation of fermentation products
Inventor: HINCHLIFFE EDWARD
IPC: C12P7/06
Filed: 1986-04-22
Granted: 1988-11-09
Abstract: The invention provides a process for the production of ethanol and a protein or peptide which is heterologous to yeast which comprises fermenting an aqueous carbohydrate-containing medium with an industrial yeast strain which has been genetically modified to be capable of expressing a heterologous protein or peptide, under conditions such that the yeast multiplies but no expression of the said heterologous protein or peptide takes place, recovering the ethanol so-formed, inducing expression of the said protein or peptide by the yeast, and obtaining the said heterologous protein or peptide therefrom. The process may be applied to the industrial production of alcoholic beverages such as beer or distilled alcohol. The yeast inevitably obtained as a by-product in the process has improved value because it provides a source of the heterologous protein or peptide. Heterologous protein and peptides which may be produced by the new process include enzymes such as beta-lactamase, beta-glucanase and beta-galactosidase and proteins of therapeutic value such as human serum albumin.
