Patent SK-63195-A3 (SK)
Title: Method of producing metallic magnesium, magnesium oxide or a refractory material
Inventor: ENGELL JOHN
IPC: C01F5/04
Filed: 1992-11-16
Abstract: Metal magnesium and pure magnesia oxide are obtained by carbothermic reduction of initial materials, such as magnesia oxide, containing small amounts of Fe, Si, Ca and Al oxides and/ or magnesia-silicate materials such as olivene, in pressure under atmospheric pressure. Metal magnesium is evaporated from the reduction zone and pure metal magnesium and pure magnesia oxide are condensed in the second condensation zone. Si is partly evaporated as SiO, which is evaporated in the first condensation zone before the second condensation zone, partly is converted to SiC and alloy of Si and Fe in reaction mixture. The initial materials can be also processed by the method, wherein their magnesia component converts to magnesia oxide in reaction mixture whilst the remaining components converts to SiC and alloy of Si and Fe. Au and infrequent siderofile elements can be obtained by lixivitation of the alloy of Si and Fe.

Title: Internal combustion engine
Inventor: MERRITT DAN
IPC: F02M37/00
Filed: 1992-10-30
Abstract: An internal combustion engine has at least one set of first and second cylinders (12,14), the first cylinder (12) having a larger swept volume than the second cylinder (14), and respective first and second pistons (16,18) movable in the cylinders. The pistons are coupled together such that they are movable in the cylinders in a cyclic manner at the same frequency. An air inlet (24) and an exhaust outlet open into the first cylinder and a fuel injector (34) provides fuel to the second cylinder. A combustion space (20) is also provided which communicates with both cylinders during at least a portion of the expansion stroke. The second piston has a crown (35) and a body portion (19), with the crown being spaced from and connected to the body portion and having an edge (37) which is relatively small in the axial direction compared to the distance between the crown and the body portion in the axial direction. The combustion space (20) is defined between the piston crown and body portion and a side wall (14a) of the second cylinder. The gap (128) between the crown edge (37) and the cylinder wall (14a) serves to inhibit ingression of fuel into the combustion space (20) until towards the end of the compression stroke. Access means (30) associated with the second cylinder for admitting fuel and/or air to the second cylinder during the induction stroke comprises a port (33) opening into the second cylinder and a valve (31) for controlling port. <IMAGE>

Title: Severing process of glass tubes or sticks and apparatus for making the same
Inventor: FABIAN ZDEN K
IPC: C03B33/06
Filed: 1999-04-19
Abstract: Parting of glass tubes (1) or sticks is carried out in vertical position by at least two opposite blades (3, 5) having cutting edges arranged in one horizontal plane. The parting proceeds so that the internal blade (3) disposed on a rotary carousel (2) forces a glass tube (1) or a stick against the opposite external blade (5) disposed on a fixed holder (4) by a pressure being sufficient for penetration of the blade (3, 5) cutting edges into the glass tube (1) resulting in indentations perpendicular to the glass tube (1) or the stick vertical axis. At the same time, the glass tube (1) or the stick rolls on a stop (7) and opposite cutting edges in the direction toward read tips (12, 13) of both the blades (3, 5) so that the indentations elongate until the glass part separates. After the glass part falls away, the bottom end of the glass tube (1) or the stick shifts due to its own weight up to a stop (7) and into the starting position is then returned by a spring (9) pressure. A parting device has in each working position a guide tube (6) and a stop (7) adjustable for height and disposed below the guide tube (7). Between the guide tube, (6) and the stop (7) there is arranged at least one pair of opposite cutting blades (3, 5) the cutting edges of which are arranged in one horizontal plane. each blade (3, 5) has a straight cutting edge with two end tips (11, 12, 13, 14) arranged at certain distance from each other on imaginary concentric circles with radii (ri1, ri2, ri3, ri4) and center in the axis of a carousel (2) rotation. When the carousel (2) is moving, rear tips (14) of each cutting edge of the internal blade (3) circumscribe a greater imaginary circle if compared with the front tips (13) thereof. Front tips (11) of each cutting edge of the external blade (5),  disposed on a fixed holder (4) outside the carousel (2), lie on imaginary circle further from the caroused (2) center than the rear tips (13).

Title: Cable protected against lighting
Inventor: GASQUE SAMUEL M JR
IPC: H01B11/12
Filed: 1997-02-28
Abstract: There is provided a cable which retards lightning. The cable includes at least one internal conductor which may be a power conductor or a signal conductor. A choke conductor is wound about the internal conductor in the shape of a spiral. If lightning strikes near the cable or a device which is attached to the cable, such as an antenna, the chock conductor presents a high impedance to the current caused by lightning and will prevent the lightning current from flowing down the choke conductor, thus entering the internal conductor, thereby preventing damage to the internal conductor and any associated electronic equipment. Preferably, a shield is also spiraled wound about the internal conductor adjacent to the choke conductor in a direction opposite to the choke conductor, whereby the angle formed by the crossing of the choke conductor and the shield is approximately 90 DEG  to block the magnetic field component of the lightning discharge.
