Abstract: 1,267,081. Leno shedding motions. STAUBLI & CO. GEB. 1 April, 1969 [8 April, 1968], No. 16941/69. Heading DIE. A dobby for controlling the movement of the standard heald 8 in the weaving of fabrics with a mixture of leno weaves and other weaves has a cam 9 driving a follower 12 to move the heald 8 between the lower sheet position, Fig. 4, and the mid-sheet position, Fig. 5, for leno weaves and a Hattersley dobby 1-6 which is controlled to actuate means 16-18 to further raise the follower 12 beyond the range of the cam so that the heald moves to the upper sheet position (Fig. 6, not shown) for normal weaves. The means for raising the follower may be a wedge 17 which slides under a follower wheel 19 on the follower when moved by the dobby jack 6, or a pivoted cam (27), Fig. 7, (not shown) moved by the jack to act on a pivoted follower (22) of the cam 9, or a fork (36) Fig. 11 (not shown) acting on a toggle link (40) connected to a pivoted follower (32).

Abstract: 1288313 Semi-conductors FERRANTI Ltd 19 April 1971 [21 Feb 1970] 8435/70 Heading H1K A lateral PNP transistor 10 of an integrated circuit is formed in a silicon wafer having a P- type semi-conductor substrate and a N-type epitaxial layer 12 in which the transistor is formed. A heavily doped layer 13 at the 11, 12 interface prevents parasitic transistor action between substrate 11 and emitter 14 which, with spacedly surrounding collector 15, are formed within base 16 comprising the bulk epitaxial layer 12; the base having a sufficiently thick separating portion and a heavily doped N+ contact region 17 being provided externally of the collector. An isolation barrier 18 of similar conductivity type to the emitter 14 and collector 15 extends through layer 12 to substrate 11. The surface portions 14<SP>1</SP>, 151, 181 of the emitter 14, collector 15 and barrier 18 are heavily doped to P + conductivity type so that 18<SP>1</SP> forms a current leakage guard ring and 14<SP>1</SP>, 15<SP>1</SP> prevent ion drift in the emitter base and collector base PN junctions, while 14<SP>1</SP> improves injection rate of charge carriers into base 16; whereby the current gain is increased. Impurity concentration figures are quoted and fabrication is by plural known diffusion steps, forming a passivating oxide layer 19 and an epitaxial layer 12, through which emitter, collector, and base contacts 20, 21, 22 extend. A conventional NPN transistor (not shown) and other circuit elements are simultaneously fabricated.

Abstract: 1289352 Agitating and circulating liquids J E OSTBERG 5 Sept 1969 43974/69 Heading B1C In apparatus for producing rectilinear unidirectional flow in a metallurgical melt, a reciprocating propelling member is at least partly immersed in the melt and disposed in non co-acting relationship with the walls of a container, and has a shape, including a substantially plane or concave face facing in one direction of rectilinear motion of the member when reciprocating, such that by motion of the member in said one direction it produces a greater resistance to motion than by motion in the other direction, hence exerts a greater force on the melt and causes the melt to move. In one embodiment, Fig. 4, an annular curved member 16 causes downward motion of a melt, as shown by the arrows, within a chamber 12 immersed in the melt. In another embodiment downward flow is caused by two cup-shaped members reciprocated by a shaft. In other embodiments (Figs. 1, 3, 5 not shown) there is only one cupshaped member, with its concave face facing upwards or downwards to produce corresponding motion of the melt in which it is immersed. Alternatively (Figs. 6 and 7 not shown) the concave face of the member may open sideways of the shaft to produce sideways motion of the melt. The member may take the form of an annular ring (Fig. 2 not shown) opening downwardly. Two spaced apart members (36) may be provided (Fig. 11 not shown), one having a downwardly facing concave face and the other having an upwardly facing concave face. They reciprocate "out of phase" to produce circulation of the melt in a container (34). In another embodiment (Fig. 10, not shown) the member (28) is a tube having an inwardly extending lip (30) at its top, the lip having an annular downwardly facing recess (32). In a further embodiment (Fig. 9 not shown), a tube has an inwardly extending annular flange, having a convex top surface and a flat lower surface The tube is reciprocated to produce motion of the melt.

The internal wall of the connector may have teeth to penetrate the conductor insulation if it is not bored. The plunger is bifurcated and tapered to allow it to enter the opening 70, and may be made of rubber or plastics.

Title: Two powder synthesis of hydrotalcite and hydrotalcite-like compounds
IPC: C01F7/784
Filed: 1995-08-15
Abstract: There is provided an improved method for making synthetic hydrotalcite by first reacting powdered magnesium oxide with a high surface area, transition alumina in a solution or suspension to form a meixnerite-like intermediate. This intermediate is then contacted with an anion source such as an acid, and most preferably carbon dioxide, to form the layered double hydroxide which is separated from the suspension by filtering, centrifugation, vacuum dehydration or other known means. On a preferred basis, the transition alumina combined with activated magnesia consists essentially of a rehydratable alumina powder having a surface area of 100 m<2>/g or greater. To make related double hydroxide compounds, still other reactants such as bromides, chlorides, boric acids, or salts thereof, may be subsituted for the carbon dioxide gas fed into this suspension.
