Title: An attachment means for the spray boom of a field sprayer
Inventor: OBERHEIDE FRIEDRICH
IPC: A01M7/00
Filed: 1985-05-23
Abstract: An attachment means for the spray boom of a field sprayer, includes a basic frame 1-3 which is connected to the field sprayer and on which frame the spray boom 5 is mounted via pivot joint members in such a manner that it is pivotable to a limited extent both in the horizontal plane and in the vertical plane, the pivotal axis for the pivotal movement in the vertical plane extending in the intended direction of travel and being disposed above the centre of gravity of the spray boom. In order to substantially simplify the complex structure for the mounting of the spray boom, whilst simultaneously substantially improving the vibrational behaviour of the spray boom, the vertical pivotal axis (15) for the pivotal movement in the horizontal plane is disposed at least approximately in the centre of gravity plane of the spray boom (5), and the mounting for the spray boom (5) on the basic frame (1) has bearings (12, 13) which are spaced from each other in the direction of travel (7). <IMAGE>

Title: Diverter valve with bypass duct obturator for twin gas turbine engine installation
Inventor: HITCHCOCK MALCOLM CHARLES
IPC: F04D25/16
Filed: 1985-09-04
Abstract: A fluid flow diverter system for use with a twin engined vertical take-off aircraft is employed to direct a portion of, or all, the working fluid from the first axial flow compressor (14) of either a by-pass engine, a twin fan engine or a variable cycle engine to either a pair of vectorable front nozzles 36 or to a by-pass duct (34).

Patent GB-2191142-A (GB)
Title: Flash prevention
Inventor: BAIRD JOHN
IPC: H01L21/56
Filed: 1987-04-22
Abstract: The formation of flash during plastic encapsulation of electronic devices may be reduced or eliminated by modifying the mold chases so that the edges of the channels (11) have a wedge shaped edge region (60) extending to the parting plane (30) of the mold (21,22). The wedge angle (69) is desirably in the range 15-30 degrees, measured with respect to the parting plane (30). The length (67) of the wedge (60,60A-B) should be sufficient to provide for heating of the thermosetting plastic (12,73) flowing therein. The plastic (73) flowing into the wedge shaped region (60) solidifies more rapidly than the plastic (12) in the main channel (11), thereby damming the wedge to prevent flash formation at the mold parting line (30). Modifications of the wedge shaped region are shown in Figure 5B (not shown). <IMAGE>

Title: Logging apparatus and method
Inventor: PASKE WILLIAM CHARLES
IPC: G01V5/12
Filed: 1987-12-11
Abstract: Downhole measuring apparatus includes a gamma radiation source 24 and at least two pairs of radiation detectors 26 - 32 carried by a housing 12 so that radiation may be emitted from the source and scattered by the environment of the housing and detected by the detectors. Each pair of detectors is arranged so that its detectors are positioned symmetrically on opposite sides of the longitudinal axis of the housing, and each pair of detectors, in combination with the radiation source, forms a different geometrical configuration so that, in general, the radiation counts obtained by the different pairs of detectors will not be redundant. The output signals from the detectors may be processed to provide data signals indicative of the radiation counts experienced by the detectors, and which may then be used to simultaneously obtain values for two or more downhole parameters. The addition of each new, independent pair of detectors permits the simultaneous solution of an additional downhole parameter. <IMAGE>
