Title: Circuit and method for producing a cross-hair cursor
IPC: G09G5/08
Filed: 1980-07-22
Abstract: A desired location is identified in a raster-scan display by a cross-hair cursor the component parts of which extend the full height and width of the display area and the intersection of which is blank. X and Y co-ordinates of the location are continually stored in registers 22,24. At the start of each line, the X co-ordinate is loaded into counter 26 which is then decremented at clock (dot) rate whereby the output 66 goes high for count zero corresponding to the required X co-ordinate in the display. Thus, a vertical line is drawn at the required position. Similarly, the Y co- ordinate is loaded into counter 28 at the start of each field or frame and decremented at line rate to produce the required horizontal line. Since the output of both counters is high at the intersection of the lines, the exclusive- OR gate 30 produces a low output at this point. <IMAGE>

Patent GB-2075611-A (GB)
Title: Compressor
IPC: F01B1/12
Filed: 1979-11-28
Abstract: Compact and inexpensive vibration free compressor that is readily assembled. It embodies, a linear type of compressor wherein a housing section (11), for enclosing a crankshaft (29) and pinions (17) of a counter. balancing synchronizer (39, 40 and 21), has axially extending support means (14) for the pinions formed integrally therewith through an inner flange (13) also integral with the housing section, so that the holes for the pinion shafts may be formed in the support means when the hole (31) in the housing for the crankshaft is formed. This assures the making of all of the holes exactly parallel and avoids time-consuming assembly work, experienced in prior art compressor manufacturing, when the housing sections are put together. By providing a large opening through the upper portion of the support means or through the bottom of the housing, an axial bore may be made to receive a piston type of crosshead (21b). By cutting down on the number of compressor parts and the manufacturing tolerances involved in the manufacture of the parts and the use of U-shaped members (141) as guides for the gear racks (37) and as retainers for the pinion shafts (18), a further saving in manufacturing cost is obtained.

Title: Laser system
Inventor: BARNIE JAMES W
IPC: H01S3/104
Filed: 1982-10-20
Abstract: To produce multiple pulses a single laser resonator has two separate discharge regions and two sets of electrodes 12, 14 and 16, 18 and preionizers 21, 23. The optical resonator is folded by mirrors 32 and 34 and the beam passes through both discharge regions between end mirrors 30 and 36. Since the multiple discharges occur within the same resonator, multiple identical pulses are produced and since the discharge regions are separated, the shock wave and medium inhomogeneity produced by a discharge in one discharge region will not disturb the others. A discharge in the region between the electrodes 12 and 14 is triggered directly from a timer 50 by a pulse forming network 70. A subsequent discharge is triggered indirectly from the timer 50 by a pulse forming network 110 coupled through a delay 90 to the timer 50. The overall mirror separation and electrode spacing define a Fresnel number suited for single transverse mode operation. <IMAGE>
