Title: Method and apparatus for pitting and slicing olives
IPC: B26D1/28
Filed: 1988-12-01
Abstract: Each olive (10) is carried in a cup (16) positioned between a coring knife (24) and a pitting knife (22) in a manner so that the longitudinal axes of the cup (16) and the knives coincide. As the cup (16) and knives rotate around a drive shaft (18) along parallel circular paths, a system of cams (28,30) extends and retracts the knives (22,24) relative to the cup (16), in order to pit the olive. After the pitting operation, the cup (16) (containing a pitted olive) continues to rotate along its circular path past a set of slicing knives (60) or water jet cutters. The slicing elements (60) are oriented substantially parallel to the plane of the cup's (16) circular path, so that the slicing elements (60) will sever the olive cleanly into slices as the cup (16) translates past them. In the inventive method and apparatus, both the pitting and slicing operations are performed on each olive (10) while the olive is held in a known orientation. The known orientation is not changed between the two operations, in order to enhance the uniformity of the resulting olive slices.

Abstract: A light-triggered thyristor module incorporates 
light-triggered thyristors and associated fiber optics for 
transmitting light from a remotely located light source. 
The isolated light-triggered thyristor module includes a 
housing having an anode contact, a cathode contact and an 
electrically grounded base plate. In the housing is 
disposed a thyristor in a semiconductor body. The 
semiconductor body has a first major surface and an 
opposing second major surface. The thyristor has an 
optical gate, cathode emitter and base regions disposed 
adjacent the first major surface and anode emitter and 
base regions disposed adjacent the second major surface. 
A cathode conductive layer and an anode conductive layer 
contact the first and second major surfaces, respectively, 
of the semiconductor body, and are electrically connected 
to the cathode and anode contacts, respectively, of the 
housing. Disposed in and penetrating the housing is also 
means for receiving an optical fiber. Additionally, a 
fiber optic locator member for holding and supporting an 
optical fiber is disposed adjacent the optical gate of the 
thyristor. The locator member is of an electrically non-­
conductive and optically neutral material such that light 
passing through a fiber within the locator member is 
substantially unaffected by the locator member. Extending 
from the fiber receiving means through the fiber optic 
locator member is an optical fiber. The fiber is 
positioned within the locator member in such a way that it 
is in optical communication with the optical gate of the 
thyristor. Lastly, an anode member electrically and 
thermally adjoins both the anode conductive layer and the 
 
 
base plate of the housing. The anode member is 
electrically insulating to allow for high voltage 
isolation of the module and thermally conducting to allow 
for heat dissipation.

Title: Formation of film superconductors by metallo-organic deposition
IPC: C23C18/08
Filed: 1988-09-01
Abstract: Superconducting thin films of RE₁Ba₂Cu₄O z , 
where RE is a rare earth metal chosen from the group 
consisting of yttrium, ytterbium, and europium, are 
produced in a non-vacuum environment using 
metallo-organic deposition techniques. A metallo-­
organic solution comprising the neodecanoates of the 
rare earth metal, barium, and copper is formed and spun 
on a single crystal substrate of strontium titanate to 
form a film thereon. The metallo-organic film is 
heated in an air environment at a temperature 
sufficient to decompose the neodecanoates, about 500°C, 
and then annealed to promote recrystallization and 
grain growth of the resulting metal oxides. The 
annealing step is preferably accomplished using rapid 
thermal annealing techniques wherein the material is 
uniformly and rapidly heated to an appropriate 
temperature for an amount of time of up to about 2 
minutes. The resulting films of material exhibit 
superconductive characteristics at elevated 
temperatures relative to the temperature of liquid 
nitrogen.

environment in which devices which perform parity checking (103) and 
those which do not (150) are connected to the same synchronous bus. 
The bus includes a parity enable line (113), which carries an parity 
enable signal indicating that the device transmitting data on the 
bus is a parity device which provides the parity of the data it 
transmits, a parity line (111), which carries the parity of the data 
being transmitted, and a parity error line (109) which carries a 
parity error signal indicating whether the receiving device detected 
a parity error. The data is transmitted in a first bus cycle, the 
parity enable signal and the parity are transmitted in the following 
bus cycle, and the receiving device transmits the parity error 
signal in the next bus cycle after that. The bus interface for each 
parity device includes a parity generator (327) and logic (519, 521, 
523, 525, 509) which generates the parity and parity enable signals 
and receives the parity error signal when the parity device is 
transmitting and which receives the parity and parity enable signals 
and generates the parity error signal when the device is receiving. 
The apparatus is used with system diagnostic apparatus which records 
the occurrence of any parity error among devices attached to the 
bus.

Title: Method of measuring a profile of an object and an apparatus for carrying out the method
IPC: G01B17/06
Filed: 1989-07-10
Abstract: A method of measuring a profile of an object 
wherein an ultrasonic wave is radiated from an 
ultrasonic transducer toward an object supported by a 
supporting member in the water filled in a water tank, 
and a wave reflected at the surface of the object is 
detected by the transducer, and an apparatus for 
carrying out the method. A traversing device moves the 
transducer sequentially to a plurality of measurement 
points on an arc equidistant from a predetermined 
rotational center while opposing the transducer to the 
predetermined rotational center. A supporting device 
moves the supporting member relative to the transducer 
and sets the object in the predetermined position under 
water. A control device delivers a drive signal to the 
traversing device to move the transducer sequentially 
to the measurement points, causes the transducer to 
radiate an ultrasonic wave when the transducer is in 
each of the measurement points, calculates a distance 
between the transducer and the surface of the object in 
accordance with a difference between the time the 
transducer radiates the ultrasonic wave and the time 
transducer receives the wave reflected at the surface 
of the object, calculates coordinates of each of the 
measurement points, and coordinates of the surface of 
the object corresponding to each of the measurement 
points from the calculated distance, and obtains the 
profile of the object from the calculated coordinate 
of the surface of the object at each of the measurement 
points.

Title: Dynamic head position tracking control for a magnetic tape playback system
IPC: G11B5/588
Filed: 1989-10-20
Abstract: A dynamic head position tracking control for a magnetic tape 
playback system employs a detected dither signal to 
determine the elevational position of a pair of magnetic 
transducing heads relative to tracks of recorded information 
being scanned by the heads. This detection is carried out 
at several locations along the lengths of the tracks being 
scanned, and a value is stored for each of the locations. 
Based upon the stored information, an estimation is made of 
a position value for the first location along the length of 
the tracks. This estimation is determined from a weighted 
extrapolation of the following two samples taken during the 
scan of the track. The elevational position of the heads is 
then dynamically controlled in accordance with the actual 
and estimated head position values.
Patent EP-0369769-A3 (EP)
Title: Liquid chromatography using microporous hollow fibers
IPC: B01D15/08
Filed: 1989-11-15
Abstract: Liquid chromatography separations of solutes are achieved using porous hollow fibers. The pores of the hollow fibers immobilize a solute-absorbing phase (preferably organic) which has a greater absorbance affinity towards at least one solute in a mixture of solutes. By passing the solute mixture through the central lumen of the hollow fibers, chromatographic separations are realized due to the greater retention time of that solute with which the immobilized phase has greater absorbance affinity. The immobilized phase may be a liquid organic which may contain a surfactant so as to form reversed micelles or it may be in the form of a polymeric gel. Separations of biological species (e.g., proteins) may thus be accomplished by means of the present invention.
Patent EP-0342148-A3 (EP)
Title: Process and installation for the thermal treatment of solids
IPC: F27B1/22
Filed: 1989-04-27
Abstract: A process and an installation for the thermal treatment of solids in an oxidising or reducing environment is proposed, in which two regenerators are interconnected via a furnace. The solids are introduced into the furncae in the centre and distributed, after burning, in approximately equal parts to the regenerators. Combustion air, which is heated in the respective regenerator by means of the solids and, after leaving the respective regenerator, is further heated for the implementation of the thermal treatment, is introduced, in each case reciprocally, into the regenerators. After completion of the thermal treatment, for example after burning of the solids with the heated gases, the hot gases are supplied to the other regenerator respectively, and transmit their heat to the solids. After a clock time, the direction of flow of the combustion air introduced and thus of the hot gases also is reversed. <IMAGE>
