Title: A laser optical projection system for balances and fine weighing instruments
Inventor: BUCKLEY MICHAEL JAMES
IPC: G01G1/18
Filed: 1983-01-12
Abstract: A laser operated optical projection for the enhanced readability and precision of balances and similarly constructed weighing instruments where the image is read either on an associated direct reading scale or by an automatic light sensor. The system is capable of operation on weighing instruments of capacities normally between 25 kg and 20 g in laboratory conditions under natural or artificial light and does not create any thermal effect which acting on the beam of the weighing instrument would lead to unqualified error. Light generated from a helium-neon laser (a) is reflected via a collimator (b) and beam subdivider (c) onto a principal reflector (e) mounted on the beam of the weighing instrument (f) and then onto a remotely situated direct reading scale (g), or via a light sensing unit (not shown) where the result is displayed on a digital display unit. When used on such weighing equipment the ultimate precision when expressed in terms of parts per million (at 1 kg) can be expressed as 0.5 ppm (minimum) at the 95% confidence level. <IMAGE>

Title: Computer system with bus cycle sharing
Inventor: CAREY RICHARD A
IPC: G06F13/362
Filed: 1983-04-27
Abstract: An interactive computer terminal system includes a CPU 4A, a direct memory access (DMA) controller, a RAM 8A, terminal display units 16-1A to 16-32A and various other units all coupled to a system bus 2A. The CPU 4A includes bus arbitration logic which assigns time slots on the system bus 2A in accordance with predetermined priority rules. To achieve maximum bus usage, a unit having a short bus cycle can utilize the bus during a portion of a longer bus cycle, being utilized by another unit, when that other unit is not transferring information over the bus. For example, the processor bus cycle equals two memory cycles, and the processor always accesses the memory during the second half of the processor cycle. Hence another cycle, e.g. a chip refresh cycle, can be activated concurrently with the first half of the processor cycle. <IMAGE>

Title: Variable-ratio transmission
Inventor: O'HEA ADRIAN RALPH
IPC: F16H19/00
Filed: 1984-06-13
Abstract: A chain or belt drive has one or more spiral chainwheels or pulleys. The driving chainwheel 5 is made to oscillate back and forth, perhaps by an eccentric cam. The driven chainwheel 3 also oscillates and drives the output shaft 1 through a one-way clutch 2. The cam driving the driving chainwheel may be shaped in such a way that a constant output speed is produced during the course of each forward stroke despite the continuously changing radius. Slack in the chain is taken up by a chain tensioner, or the spirals are shaped so that no slack occurs. The gearing ratio is changed by changing the relative positions of the output shaft and of the arc through which the driving chainwheel oscillates. The complete transmission generally consists of two or more of these drives, all mounted on the same output shaft and each taking the load in turn. <IMAGE>

Title: Underwater sealing of an oil-lubricated shaft bearing
Inventor: OTTO FRIEDRICH-WILHELM
IPC: F16J15/40
Filed: 1984-11-08
Abstract: For the sealing of an oil-lubricated bearing (2, 3) of a drive shaft (1), a leakage space (20) and an adjoining oil chamber (30) are arranged between a slide ring seal (11, 12) and the bearing. The oil chamber is bounded by two outer lip seals (25, 27) and contains a further, normally unloaded inner lip seal (26). If a water pressure, which is higher than the normally low oil pressure in the oil chamber (30), should build up in the leakage space (20) and a collecting chamber (41) connected therewith, the oil pressure in the forward oil chamber compartment (30b) is increased to about half that of the water pressure. The changing of the pressures in the oil chamber compartments (30a and 30b) activates the inner lip seal (26), which, however, is subjected to only half the pressure difference between the ambient water pressure and the low oil pressure in the bearing. <IMAGE>
