Title: Epoxy resin composition and semiconductor sealing material comprising same
Inventor: TOGASHI EIKI
IPC: C08K3/36
Filed: 1990-01-17
Abstract: Disclosed is an epoxy resin composition comprising, as basic components, (A) an epoxy resin, (B) a phenol-novolak resin, (C) a curing promotor and (D) a filler.  Pulverized or spherical silica having specific particle size characteristics is used as the filler (D). Preferably, a halogenated epoxy resin and antimony oxide are further incorporated in this epoxy resin.  This epoxy resin composition shows a very small molding shrinkage.  If a dialkylurea derivative is used as the curing promotor (C), the stability of the composition at about 100°C is drastically improved and the flowability of the composition is improved.  Accordingly, precision injection molding becomes possible, and the effect of sealing a semiconductor is enhanced.

Title: Process for preparing proteins from a protein-containing substance
Inventor: NEUMUELLER WALDEMAR
IPC: A23K20/147
Filed: 1994-11-22
Abstract: In a process for preparing proteins from a protein-containing substance, the substance is dispersed in an alkaline solvent with a pH of over 11.5 and at a temperature of under 30 °C.  The proteins in the substance are thus dissolved.  The resulting solution is then neutralised  and the proteins in it are concentrated.  To improve the profitability of the process in large-scale manufacture, the protein-containing substance is treated with a protease before dispersion in the alkaline solvent.

Title: Process and apparatus for the cleaning of dust laden gas
Inventor: DEHN GUENTHER
IPC: B01D46/24
Filed: 1996-06-21
Abstract: In a process for the cleaning of dust laden, preferably hot gas with the aid of ceramic filter candles which are open at one end stacked above one another in levels in a raw gas space, and connected to a clean gas space, these filter candles are cleaned by way of pulsed gas, which is blown into the filter candles for a short period of time from the side of the clean gas space and against the direction of raw gas flow.      In the raw gas space the gas to be cleaned and the dust loosened by the cleaning are guided separately so that the loosened dust is guided to the dust removal structure of the raw gas space without once again mixing with the gas to be cleaned. The process is advantageously carried out in a filter housing wherein the filter candles are connected to laterally spaced apart supporting collectors. The filter candles in one level are separated from the filter candles in the level thereabove by an ash removal mantle.

Patent CA-2188321-A1 (CA)
Inventor: HANSEN LEONARD ROY
IPC: F24H7/02
Filed: 1996-10-16
Abstract: A gas fuelled water heater for small scale (4-6kw) supply has an upright, tubular water jacket with a multi-jet gas burner at the lower end and a finned multi-tube preheater at the upper end. The incoming water is preheated before it enters the jacket. Heat exchange is promoted by water tubes which criss cross the diameter of the jacket. These are staggered radially by 10-35 degrees in order to slow the passage of the flue gases without creating back pressure.          A  thermostat  controls  gas  supply  from  a  bottled  or reticulated supply. As the heater is connected in circuit with a domestic hot water tank it can supplement or replace electric  water  heating.  The  heater  needs  no  electric current and can operate in areas without gas or electric reticulation.

Title: Voice Band Signal Cell Assembly Apparatus for ATM
Inventor: TAMURA KAZUNORI
IPC: H04L47/43
Filed: 1997-01-28
Abstract: A discriminating section determines whether a voice band signal is "voice" or "data". When the voice band signal is voice, a voice detector detects the presence or absence of voice in the signal. If silence is detected, a cell assembly section prohibits transmission of cells. In the meantime, when the voice band signal is data, a carrier detector detects the presence or absence of a carrier. A cell assembly section sends out a cell in response to the presence of the carrier in the input signal, while prohibiting the cell transmission when no carrier is detected in the input signal. The apparatus reduces the number of cells transmitted and achieves a high transmission efficiency.

IPC: A63B69/00
Filed: 1997-02-10
Abstract: An exercising device of the type that may be used in hand to hand combat training or to enhance hand, eye and foot reflexes and coordination is disclosed. The device includes a central longitudinal body which is generally vertically oriented and has at least one elongate cross member, having two opposing ends, pivotally mounted on the central body. The opposing ends extend radially outward in opposite directions from said central body allowing the cross member to rotate about the longitudinal axis of the central body. When one of the ends of the cross members is struck by the hand or foot of an operator the end moves rotationally away from the operator while the opposing end moves rotationally toward the operator thereby requiring the operator to react defensively to avoid being hit by the opposing end. The cental body also includes an upper and a lower shaft and the cross members have bores extending through them that are generally perpendicular to the longitudinal axes of the respective cross members. The upper and lower shafts are received within the respective bores thereby permitting the cross members to rotate about the shafts and hence the central body.
