Title: Ground-supported implements
Inventor: MAHER LOUIS EDWARD
IPC: A01B63/22
Filed: 1981-11-12
Abstract: A folding roll 10 has rolls 16, 17 supported on booms 18 which pivot from the transport position shown to an operative position in which they span the strip of ground to be treated, by means of energising rams 34 which pivot the wheel- supporting arms 28, 29 rearwardly about skew axes C-C. This turns wheels 24 inwardly so that moving the implement rearwardly will cause the booms to begin their opening movement. When the booms have been partially opened in this way, the wheels 24 are retracted and the continued rearward movement of the implement, now supported on rolls 12, 16 and 17, will move the booms into their fully open operational position. The booms are locked in this position so that the towing tractor can move forward to commence the rolling operation. The reverse operation is performed to recover the transport position. <IMAGE>
Patent GB-818494-A (GB)
Abstract: 818,494. Radar. ALBISWERK ZURICH A.G. Sept. 3,1956 [Sept. 2, 1955], No. 26909/56. Class 40 (7). Relates to a ship-borne radar system for directing anti-aircraft guns comprising an unstabilized search radar 1 which determines the azimuth α<SP>1</SP>z of a target relative to the unstable deck plane and a fire-directing radar 3 stabilized against roll # and pitch y, the azimuth αz of the target in the stabilized co-ordinates being given by where t is the target elevation. In a first embodiment the aerial 2 of the search radar 1 rotates continuously about an axis normal to the deck plane and the instantaneous azimuthal position α<SP>1</SP> of the aerial 2 in said plane is applied together with the roll and pitch angles # and y and the mean angle of elevation # of the aerial 4 of the stabilized radar 3 to a computer 5 which computes in accordance with the above equation the corresponding azimuth angle α in the stabilized co-ordinates. The output α from the computer 5 is applied to control the angular co-ordinate of a search P.P.I. 6 and a rotatable cursor is continuously aligned with the target response to produce an electrical signal representing the stabilized target azimuth αz which is applied to control the azimuth position of the aerial 4 of the stabilized radar 3. The aerial 4 scans in elevation about the mean angle # until the target is detected. In a modification, Fig. 2 (not shown), the angular co-ordinate of the P.P.I 6 is controlled directly by the unstabilized azimuth angle α<SP>1</SP> and corresponding values of α<SP>1</SP>, # and y are continuously stored during each rotation of the aerial 2. The cursor on the P.P.I. 6 now produces an unstabilized target azimuth signal αz<SP>1</SP> which is applied to the storage device to produce corresponding values of # and y which are applied together with α<SP>1</SP>z and the instantaneous elevation t of the aerial 4 to the computer 5 to produce the required signal αz.

Title: Integral combined core and back plate for loudspeaker and process for fabricating the same
Inventor: LANE THOMAS J
IPC: H04R9/02
Filed: 1982-08-09
Abstract: The magnet driver for a loudspeaker employs an integral combined core and back plate fabricated from a flat strip of metal as distinguished from casting or forging from a billet. In a first forming step, the center of the strip is formed into the shape of a dome, retaining original thickness, the height and width of the dome being substantially greater than the height and width of the formed core of the magnet motor. Thereafter, the width of the dome is reduced by compressing the walls of the dome and at the same time forming a flat circumferential back plate flange about the base of the dome. Then, the height of the dome is reduced and the top of the dome is flattened by axially compressing the dome while maintaining the walls of the dome vertical. Finally, the formed unit is severed from the metal strip and trimmed. The thickness of the dome walls and flange forming the fabricated core/back plate is essentially that of the original strip of metal. The core portion is hollow. <IMAGE>

Patent GB-2125973-A (GB)
Title: Self-test method and apparatus
Inventor: PARKER KEITH WAYNE
IPC: G01R31/30
Filed: 1983-07-20
Abstract: A self-test system is disclosed wherein a microprocessor controlled system 10 under test, including a ROM 10c and a microprocessor 10d, may generate a raise-to-maximum signal. In response to this raise-to- maximum signal, a power supply generates a supply voltage having a magnitude equivalent to the maximum rated voltage of the power supply. A self-test program encoded in the ROM 10c directs the microprocessor 10d to interrogate the components of the system under test 10a when energized by the maximum rated supply voltage. The microprocessor controlled system under test 10 then generates a lower-to-minimum signal. In response to this lower-to-minimum signal, the power supply generates a supply voltage having a magnitude equivalent to the minimum rated voltage of the power supply. The microprocessor 10d, under the instructions of the self-test program, interrogates the components of the system under test 10a when energized by the minimum rated supply voltage. When the raise-to- maximum signal and the lower-to- minimum signals are not generated, the power supply develops a nominal power supply voltage for energizing the components of the system under test. The components of the system under test are interrogated when energized by the nominal power supply voltage. Since the components of the system under test are energized by a supply voltage having a magnitude ranging from a minimum to a maximum rated power supply voltage while being interrogated by the microprocessor during the self- test mode, all of the defective or potentially defective components of the system under test will fail during the performance of the self-test interrogation. Replacement thereof will ensure that the system will operate more efficiently and more reliably. <IMAGE>
