Title: Processes for producing high strength cold rolled steel sheets
IPC: C21D9/46
Filed: 1980-11-27
Abstract: A low-alloy steel is subjected to hot rolling, optionally hot coiling, then cold rolling and continuous annealing. The continuous annealing is performed by soaking the sheet at 730 to 850 DEG C for from 20 seconds to 2 minutes, whereafter the sheet is rapidly cooled with a cooling rate of from 30 to 300 DEG C/sec. If required, an overageing treatment at 300-500 DEG C may be imparted to the sheet, preferably by stopping the rapid cooling at an appropriate temperature to avoid reheating of the sheet. The composition of the steel is as follows:  Element             Wt%  C                   0.05-0.12  Si                  1.2 max  Mn                  0.7-1.5  P                   0.04-0.15  Sol Al              0.01-0.10  Fe  [and impurities]    Balance. e

Title: Switching apparatus for load matching of wind-driven electrical generators
IPC: H02J7/14
Filed: 1981-01-23
Abstract: A switching arrangement for matching an electrical load to the voltage output of a wind-driven generator where the loads are an even number of batteries or electrolytic cells (16), includes switching units (10) each having four terminals. Each switching unit has two switching states A and B, the odd numbered switching units (10a, 10c etc.) having pairs of batteries or cells connected between first and third, and second and fourth terminals so that when the switching unit is in State A, the batteries are in parallel and when in state B they are in series. The even numbered switching units (10b etc.) each serve for the interconnection of adjacent pairs of batteries in series or parallel. Control means responsive to the voltage output of the generator effects a switching sequence at given voltage thresholds to switch the batteries progressively from parallel arrangement to series arrangement as the output voltage from the wind-driven generator increases from a minimum to a maximum. <IMAGE>

Title: Shorted-emitter thyristor device
IPC: H01L29/417
Filed: 1981-03-02
Abstract: In a thyristor device the dynamic characteristics, e.g. critical dV/dt, of the thyristor may be improved by means of shorts 2 between the base layer 4 and the emitter metallisation layer 9. Such shorts, however, slow the rate of conduction spreading. To overcome this the series resistance of the shorts is made at least equal to the maximum effective lateral resistance of the base layer between the shorts by means of a layer 7 of resistive material provided between the upper surface of the columns 3 of the shorts and the emitter metallisation layer 9. The resistive material may be silicon of the same type as the base layer but possessing higher resistivity or a cermet film. In another form in the upper surface of the columns of the shorts, in contact with metallisation layer, a moat surrounding a central land is etched to leave only a relatively small contact area. <IMAGE>

Title: Control circuit arrangement for an electromagnetically operated power tool
Inventor: HUBER SIEGFRIED
IPC: H03K17/292
Filed: 1982-11-12
Abstract: A solenoid (10) is provided connected in series with a thyristor (11) for controlling energisation of the solenoid by an A.C. supply in response to a trigger signal applied to the gate of the thyristor (11). Also connected in series with the solenoid (10) and the thyristor (11), in a primary circuit, is a trigger control switch (12), which, when closed, does not energise the solenoid (10), since the thyristor (11) has not been triggered, but initiates the generation of a trigger signal by a trigger control circuit (15) after a delay. The trigger control circuit (15) incorporates delay circuit means (20), additional circuit means in the form of a flip-flop (21) and a zero crossing detector (22) for preventing generation of a further trigger pulse while the main trigger switch (12) remains closed, and trigger pulse generating means (24, 25) for applying a trigger pulse to the gate of the thyristor (11). Release of the trigger control switch (12) effectively isolates the primary circuit including the solenoid (10) thereby protecting the solenoid (10) in the event of failure and short-circuit of the thyristor (11). The circuit is particularly applied to tackers. The thyristor (11) may be triggered for an adjustable part of a half-cycle of the A.C. supply to control the power of each impulse. Adjustment is set by a potentiometer (27). <IMAGE>

Abstract: A flywheel mechanism (5) rotatable with a shaft (4) comprises a flywheel (10), a thrust member (13), and an expander mechanism (15, 16, 17) comprising angularly spaced balls and ramps arranged to cause one of the members (10, 13) to move axially and actuate a brake pressure modulator (3) when the flywheel and the thrust member are relatively displaced from a predetermined angular alignment. The thrust member (13) is carried from the shaft (4) by a mounting (18) comprising a driving flange (19) coupled to the shaft (4), and a clutch plate (21) in frictional engagement with the thrust member (13) and driven from the flange by a coupling (20, 23; 36, 37) which enables the thrust member (13) to articulate and move radially with respect to the flywheel (10). A bias force is applied centrally to the movable member (10, 13) by lever (24), and the articulating mounting (18) ensures that the force is distributed substantially equally between the balls (15). Rotation of lever (24) actuates an anti-skid valve mechanism. A further embodiment (fig. 3, not shown) discloses a different lever and valve arrangement. <IMAGE>
