Patent ZA-9210099-B (ZA)
Title: Roll of compressed fibrous mat, method and device for obtaining it
Inventor: BICHOT BERNARD
IPC: B65H18/22
Filed: 1992-12-30
Abstract: The baler consists of two endless flexible belts (17, 18), each covering approximately a half of the bale being rolled, which is made from a strip (19) of a compressed fibrous material. The completed roll is discharged from the baler in the same direction as that in which the strip (19) is introduced. The strip of fibrous material (19) is compressed by passing it between two compression units (5, 6) at the inlet side of the baler, e.g. in the form of endless belts which compress the strip without slipping. In a variant of the design the fibrous strip can be held in its compressed state by a metal pressure plate, and as each bale is completed it can be wrapped in a layer of a film material.

Title: Hybrid interleaver for turbo codes
Inventor: SUNG-HYUK SHIN
IPC: H03M13/00
Filed: 2002-01-29
Abstract: A turbo code encoder with a hybrid interleaver having two recursive systematic constituent code (RSC) encoders. The system encodes a finite sequence of informative bits without requiring a plurality of tail bits to flush the registers of each encoder to an all-zero state.

Abstract: The method provides for the use of Cupressus arizonica pollen harvested by gravity under optimum climatic conditions, selected on the basis of macroscopic and microscopic criteria and having a degree of purity of not less than 99.5%. This pollen is then preserved from deterioration by freezing at -30 degree C. The method also provides for the preparation of an allergenic extract by double extraction using two different concentrations of NH4HCO3 and subsequent concentration of the extract by precipitation with (NH4)2SO4. The allergenic extract so obtained is then used to prepare an ELISA test which is capable of detecting the presence of Cupressaceae-antigen counter-IgE in at least 75% of individuals affected by such pollen. The test is also highly specific.

Patent PT-101450-B (PT)
Inventor: VILLAX PETER
IPC: A61M16/00
Filed: 1994-02-02
Abstract: A new inhalation device, which during operation causes an aerosol to be formed inside a chamber such as a capsule (4) which occludes one end (3) of the inhalation tube (1), the capsule having holes at its extremities (7,8) which admit airflow. The airflow causes the powder contained inside the capsule to be surprisingly transported to the capsule extremity contrary to the direction of inhalation, that is towards the air entry holes in the capsule, and then to form an aerosol until all powder has been removed from the capsule or chamber through the tube (1), the duration of inhalation being chiefly regulated by the size and proportion of the capsule holes. The tube (1) has air inlets downstream of the capsule to permit a balanced airflow that will transport the finely suspended powder into the lungs, maximizing the fraction of medicament deposited therein. <IMAGE>

Title: Use of isovaleramide as a mild anxiolytic and mild sedative agent
Inventor: BALANDRIN MANUEL F
IPC: A61P25/20
Filed: 1994-06-11
Granted: 2001-02-01
Abstract: Isovaleramide has been found to exhibit mild anxiolytic (anxiety-reducing) activity at low to moderate dosage levels and mild sedative activity at somewhat higher dosage levels. In contrast to certain other materials thought to be anxiolytic or mildly sedative, isovaleramide is non-cytotoxic and does not paradoxically stimulate the central nervous system. Isovaleramide is therefore useful as a mild anxiolytic and mild sedative agent which can be made available to the general public.
