Title: Method and apparatus for filling trays with rod-shaped articles
Inventor: MIELKE JOHANNES
IPC: A01G9/08
Filed: 1984-04-09
Abstract: Cylindrical rod-shaped articles (109) which carry or are about to carry seeds or cuttings, are transported by a conveyor (124) in a direction at right angles to their axes to a row forming station where they are picked-up and held in flutes at the underside of a suction head (131) to form a row. The suction head (131) is then lifted and a pusher (134) transfers the row, by moving the articles (109) axially, into an adjacent tray (2c) which has rows of spikes on which the articles are impaled or compartments for receiving discrete articles. If the seeds or cuttings are to be implanted subsequent to introduction of the articles into the tray, the exposed end face of each article is formed with a recess during or immediately after introduction into the tray. All the articles of a row are transferred in a single step and the tray is lowered to receive successive rows. The trays can be tilted from horizontal to vertical positions prior as well as subsequent to reception of the rows of articles. <IMAGE>

Patent GB-846545-A (GB)
Abstract: 846,545. Electric indicating systems. BRITISH THOMSON-HOUSTON CO. Ltd. Jan. 30, 1957 [Feb. 9, 1956], No. 4094/56. Class 40 (1). [Also in Group XXXV] In a circuit for indicating whether two A.C. signals are in phase or 180 degrees out-of-phase comprising two transistors in which one of said signals is applied differentially to the transistors whilst the other of the signals is applied in parallel to the transistors, each transistor has an output circuit in one of which current flows when the signals are in phase and in the other of which current flows when the signals are 180 degrees out-of-phase, the output circuits including a differential relay having two operating coils respectively connected in the said circuits. The transistors T1, T2 which have a reference source V applied differentially to their collector circuits over transformer T and the signal whose phase is to be detected applied to their baseemitter circuits in parallel from terminals 8, 9, conduct only when the collector voltage is negative simultaneously with negative base current, and in consequence, current flows through coils 1 or 2 of a differential relay according to whether the input signal is inphase or 180 degrees out-of-phase with the reference signal. The output of a temperature measuring bridge, Fig. 3, containing a thermistor 7 is connected to terminals 8, 9 of the arrangement, Fig. 1, which serves to indicate balance when resistor R2 is adjusted; the setting of the resistor being a measurement of temperature. The arrangement can be used for automatic temperature indication by presetting resistor R2 so that the relay contacts change-over when the desired temperature is obtained.

Title: Detection and correction of magnetic interference in the surveying of boreholes
Inventor: COBERN MARTIN
IPC: E21B47/022
Filed: 1985-05-09
Abstract: A method is presented, for use in borehole drilling for correcting errors in azimuth determination resulting from variations in the earth's magnetic field to which a measuring instrument is exposed. The method distinguishes between variations in the earth's magnetic field caused by the drillstring and variation caused by external sources, and the method corrects only for errors caused by the drillstring. If the error is caused by the drillstring, an azimuth correction is made based on dip angle data, thereby reducing errors caused by scale factor variations since dip angle is a ratio quantity of magnetic field components.

Title: Improved semiconductor die-attach method and product
Inventor: SOLOMON DAVID A
IPC: B23K35/26
Filed: 1986-06-16
Abstract: A method for attaching semiconductor dies to metal package supports is characterised by the use of a homogeneous soft solder preform. The soft solder preform has a uniform microstructure which is free from contaminants, such as organic materials, as well as from intermetallics, and has a particule size below about 10 microns. Such homogeneous preforms provide a bonding layer between the semiconductor device and a metal support frame which is initially free from voids and which resists deformation and cracking during subsequent power cycling of the device. The reduction in voids and cracking, in turn, allows for uniform head dissipation in the device, eliminating hot spots and extending the life of the device.

Title: Electrolytically etching linear impressions in grain-oriented trical steel
Inventor: BECKLEY PHILIP
IPC: C21D8/12
Filed: 1987-08-22
Abstract: This invention relates to a method of enhancing linear impressions formed in the surface of grain oriented electrical steel strip, by electrolytically etching said impressions with e.g. citric acid. The impressions may be formed by mechanical wheel scribing or by surface ablation, e.g. by spark discharge or laser treatment, and may be continuous or discontinuous in the form of spots or lines. In accordance with this invention therefore, the initial generation of light impressions in steel strip formed by mechanical wheel scribing or spark ablation techniques can readily be enhanced by application of the electrolytic etching technique to produce a material exhibiting values of power loss (reduced from the original unscribed loss value) which are substantially anneal-proof. In comparison, conventionally scribed material shows no resistance to a high temperature anneal as far as loss reduction is concerned.

Title: Printing on containers with hyperboloidic surfaces
Inventor: VESBORG STEEN
IPC: B41F15/08
Filed: 1987-10-20
Abstract: Containers, such as disposable plastics bottles 10, and having hyperboloidic surfaces, receive printed information in areas 12, 14 of these surfaces by line contact between the surfaces and a print-transferring element. Preferably, Fig. 4, printing is achieved by a doctor blade traversing a planar, but flexible, silk-screen; the hyperboloidic surface is partly rotated and partly translated with the doctor blade so that the screen stays in line contact with the surface along a generatrix for the surface. The shape of container serves to prevent visible deformation when a partial vacuum is created during dispensing of the contents.

Title: Fluid dynamic structures containing anisotropic material
Inventor: JERONIMIDIS GEORGE
IPC: F03D7/02
Filed: 1989-03-23
Abstract: An elongated structure such as a blade or fin, and especially the blade of a wind turbine, comprises an outer part shaped so as to generate useful thrust when set in motion relative to surrounding fluid at an appropriate angle of attack, and a reinforcing inner part. At least one of these parts includes material of anisotropic character, whereby elongation or bending of the length of the structure causes the outer part to twist about its length, so varying the angle of attack. As wind speed increases, and with it the risk of overloading or damaging the blade or turbine, this angular variation progressively moderates the forces upon the blades and so avoids the overloading.
