Title: Spherical roller bearing
IPC: F16C23/08
Filed: 1979-08-15
Abstract: A spherical roller bearing comprises inner and outer raceways (12, 14) and a plurality of rollers (15). Each raceway (12, 14) is formed as the rotation of an arc of a circle Ro, Ri) about an axis. The external surface of each roller (15) is formed as the rotation of another arc about an axis, which said another arc is composed of at least two different curves (Rr1, Rr2), all such that in use of the bearing there is a resultant frictional moment on each roller causing it to be skewed to a skew angle which is positive. <IMAGE>

Title: Mounting of gun sights
IPC: F41G1/393
Filed: 1979-11-09
Abstract: On the body 7 of a tank are mounted a gun 5 which pivots about axis 1 and a sight 8 which pivots about an axis 2. To ensure that the sight 8 is aligned with the gun 5 for all angles of elevation the sight 8 and gun 5 are joined by a link 13. Adjustments must be made to ensure that the axes 1, 2, 3 and 4 lie at the corners of a parallelogram. This is done by setting the gun at mid-range and adjusting turnbuckle 13A until the sight is aligned with it. The gun is then lowered to a given elevation and the error in the elevation of the sight is noted. The gun is then raised to another elevation and the error in the elevation of the sight again noted. From the two error values the adjustment required to the distance between axes 2 and 3 and the distance between axes 3 and 4 can be calculated. A special adjusting mechanism (Fig. 2: not shown) is used to carry out these adjustments. <IMAGE>

Title: Dual flush apparatus e.g. for toilet cisterns
IPC: E03D1/08
Filed: 1982-01-11
Abstract: A conversion apparatus for converting a single flush syphonic action liquid discharge apparatus into discharge apparatus capable of providing dual flush capability. The apparatus includes a control valve unit (14) connected in the operational linkage (9, 10, 13) for a syphonic unit (6), the valve being normally open. The arrangement is such that on operating the linkage to start syphon action the valve unit (14) is automatically closed, so long as the linkage is held in the operated setting, and such that on release of the linkage the valve opens. The valve connects via an air pipe (19) to the syphon unit at a location (20) where admission of air stops syphon action, and via a second pipe (21) to a point below normal full level of the container for the liquid to be discharged. In operation if linkage is released after starting the syphoning the valve is open to allow air to enter syphon unit when water level falls to said point, and if linkage held valve is closed to allow full water discharge. <IMAGE>

Title: Device for controlling the spark starting in an electric or electronic welding machine
Inventor: SANTINI CARLO
IPC: B23K9/073
Filed: 1982-07-09
Abstract: An arc-welding machine having a potentiometer 19 for manual adjustment of the current delivered by a generator 2 includes a control circuit 25 which controls the current delivered by the generator in dependence on the voltage between the tip 13 of a welding torch 12 and a workpiece. When the tip 13 touches the workpiece 15 with a relay-operated switch 9 open, a comparator 30 turns on an LED 29 so that a phototransistor 36 applies a low resistance across inputs 17, 18 of the generator 2 so that when the switch 9 is closed the generator 2 initially delivers current at its lowest current setting. Subsequently when the tip 13 is lifted from the workpiece 15 to establish an arc, the voltage between the tip 13 and workpiece 15 increases causing the comparator 30 to turn off the LED 29 whereby the current delivered by the generator 2 is that set by the potentiometer 19. <IMAGE>
