Title: Filter depict acceleration of angular velocity - uses feedback from two counters to input addition logic
IPC: H03H17/02
Filed: 1973-08-24
Abstract: The digital filter produces digital output signal characterising the acceleration associated with an input signal representing an angular speed. The input signal (x) is passed via logic (12) to a first forwards/backwards counter (2). This counter's output (u) is passed to a comparator (4) where it is compared with a first shift-register's (6) contents. The comparator's output is passed to the input of a second forwards/backwards counter (3) whose output (y) is likewise fed to a comparator (5) for comparison with the contents of a second shift-register (7). The outputs of both comparators are fed back to the input logic. The logic forms the sum x-y-u and applies it to the first counter. (At equilibrium u=O, and x=y).

Title: Split bearing with slightly inclined mating surfaces - prevents distortion on bearing bore by bearing cap bolts
IPC: F16C35/02
Filed: 1975-02-05
Abstract: The split bearing consists of a base (1) and a cap which enclose a bore (3) and are joined together by bolts through the holes (5). If the mating surfaces of the two parts are truly flat the bearing bore distorts to an oval shape when the bolts are fully tightened due to a high pressure in the areas between the bore (3) and the bolts holes (4). If the joint surfaces (6), (7), (8), (9) are inclined at a small angle (alpha) of about 30 minutes with the inclined surfaces intersecting the diametral surface at the points (10), (11), i.e. close to but outside the bolt centre lines (5), this region of high pressure is eliminated and the distortion to the bore is avoided.

Title: Conversion of coherent light with different wavelengths - into a coherent light with one wavelength
IPC: H01S3/108
Filed: 1976-08-05
Abstract: Coherent polychromatic light is converted to coherent monochromatic light. Process comprises pumping a laser till it produces spontaneous radiation of coherent light components with a number of wavelengths. A laser medium is then irradiated with these light components.
