Abstract: 1,220,315. Semi-conductor devices. BROWN, BOVERI & CO. Ltd. 14 July, 1969 [15 July, 1968], No. 35239/69. Heading H1K. In a semi-conductor device having three regions of alternate conductivity types, the junctions between which emerge at the edge of the body, the edge is bevelled and an annular groove is formed in the smaller face extending completely through the region in which it is formed to divide this region and the associated junction into two parts. As shown, Fig. 2, the edge 5 of a thyristor is bevelled and a groove 11 is ultrasonically machined in the upper face 1 to divide the upper P-type base region into two portions 4, 12. This groove allows the depletion layer associated with the junction between regions 2 and 3 under reverse bias to spread further into region 3 without surface breakdown occurring since without the groove breakdown would occur as soon as the upturned edge of the depletion layer contacted the junction between regions 3 and 4. The semi-conductor body is of Si and is mounted on a Mo support 6. The emitter region 9 and its electrode 8 are annular and surround a central gate contact (not shown). The angle α between the wall 14 of the groove 11 and the junction between regions 3 and 4 is preferably 20 degrees or less.

Patent ZA-811586-B (ZA)
Title: Process and installation for the intermittent cleaning of dust-laden crude gases
Inventor: BERZ W
IPC: B01D46/30
Filed: 1981-03-10
Abstract: An intermittently operated apparatus for cleaning dust laden gases has a gas-tight housing, a pair of spaced gas-permeable walls holding a filter bed consisting of granular filter material. A centrally located conveying pipe is mounted to the housing for regenerating the filter bed after a predetermined amount of operating time. A high electric potential is applied in the region of the filter bed for removing dust particles from the dust laden gas which is flowing through the permeable walls and the filter bed. From time to time, the gas cleaning mode is interrupted and the granular filter material of the filter bed is regenerated by fluidizing the same in the conveying pipe. A system comprising a plurality of such filtering apparatus always maintains one of the apparatus in a regenerating mode while the remaining filter devices are in gas cleaning mode. Thus, the simultaneous operation of cleaning and regenerating is accomplished. The use of a filter bed having a thickness of about 25 to 100 mm. and consisting of granular filter material having a grain size of about 0.5 to 2.0 mm. in combination with application of high electric potential charge of about 10,000 to 60,000 volts achieves significant improvement over prior apparatus and methods.

Title: Pateurizable,freeze-driable hemoglobin-based blood substitute
Inventor: HSIA JEN-CHANG
IPC: A61K38/16
Filed: 1988-05-04
Abstract: The present specification describes a process by which a blood substitute (hereinafter referred to as "HemoSafe") is derived from uniformly stabilized monomers and polymers of deoxyhemoglobin in its tight (T) conformation, with oxygen affinity similar to that of human blood. Two classes of HemoSafe are derived respectively from animal-hemoglobin and human-hemoglobin. HemoSafe (animal) differs from HemoSafe (human) in that it is free of polymers in order to reduce potential immunogenicity if used in man. Both types of HemoSafe may be derived in the following manner. The stabilized deoxyhemoglobins are converted to their carbonmonoxy derivatives (CO-HemoSafe) which are then stable under pasteurization conditions to render them viral disease transmission-free. CO-HemoSafes are stable for 2 months at 56 DEG C in either the solution or the freeze-dried state. For transfusion CO-HemoSafes are easily oxygenated under sterile conditions by photoconversion yielding oxy-HemoSafe. In addition a transfusable met-hemoglobin derivative for treatment of cyanide poisoning, is derived by converting oxy-HemoSafe to met-HemoSafe.

Title: Container adapted for stacking
Inventor: ROSS JOHN ALEXANDER
IPC: B65D5/00
Filed: 1994-07-01
Abstract: A container formed by wrapping a slotted flexible sheet about rigid end panels having projections that extend through the slots. The projections include stacking projections which engage recesses in the end panels of adjacent stacked containers and support projections at the corners. The support projections engage each other when the containers are stacked to provide resistance to lateral loading.

Title: Apparatus for avoiding crosstalks problems when locating a vehicle travelling along means for propagating electromagnetic waves
Inventor: FOURNIER DENIS
IPC: G01S13/84
Filed: 1996-06-24
Abstract: The system is used with a vehicle (V) having an transmitter (E) of e.m. waves and a receiver (R) for the waves returning from a reflector (R') as it passes along the length of a propagation medium (P) of e.m. waves. The Transmitted ( SIGMA e) and reflected ( SIGMA r) waves are compared (C) and a processing module (T) determines the distance between the reflector and the vehicle. The wave emissions and reflections are alternated by sequencers to synchronise the system with a number of positioning devices on vehicles using a transmission network supported by the propagation medium. The sequencers may be placed in the ground and transmit to reflectors the moment when they must be reflecting and to transmitters when they must transmit.

Title: Coin dispenser arrangement.
Inventor: TOKOYODA YUJI
IPC: A63F5/04
Filed: 1999-09-22
Abstract: A coin dispenser arrangement (1) for a gaming machine has a bucket portion (2) for accommodating a plurality of coins and discharging the coins one by one, and a passage (5, 6) for guiding the discharged coins to a predetermined position, wherein the passage (5, 6) has a coin face adjustment (5a) for changing facing direction of the discharged coin to an optional facing direction. Because facing direction of coin discharged from the bucket portion can be changed optionally by the coin face adjustment, the passage does not need to have a gently sloped curve for changing the facing direction of coin. The inside space of the housing of gaming machine can be saved due to the shortened passage by eliminating the curve. Time required for paying out coins can be shortened. Also, when the curve is eliminated, coin clogging rarely occurs. As a result, coins can be smoothly paid out. <IMAGE>
