Abstract: A set of surgical products which includes an attachment mechanism for modular surgical products. The set includes a plurality of first components and a plurality of second components. One of the first components and one of the second components are to be selected for engagement with each other.      The components each include an indexing means including a key on the first components and a corresponding slot on the second components for mating with the key. The orientations of the keys and slots vary, so that only first components having a key orientation that is similar to and aligns with the slot orientation of a second component will properly mate together and so that first components will not properly align and mate with second components having slot orientations that are different from the respective key orientation.

Title: Magnetic head position control apparatus
Inventor: YOKOTA TETPEI
IPC: G11B11/10
Filed: 1990-08-21
Granted: 1999-07-20
Abstract: A magnetic head position control apparatus for driving the magnetic head of a disk recording apparatus toward or away from the recording surface of a magneto-optical disk to effect position control of the magnetic head.  Changes in the distance between the magnetic head and the magneto-optical disk are detected  from changes in capacitance between a capacitance detection electrode mounted on the magnetic head and a surface of the magneto-optical disk.  An oscillator circuit connected to the capacitance detection electrode varies its oscillation frequency in response to changes in capacitance and detects such frequency variations and controls the position of the magnetic head for maintaining it at a constant predetermined distance from the magneto-optical disk.

Title: Arrangement and method for conducting substance and lock therefor
Inventor: BRADDICK BRITT O
IPC: E21B33/16
Filed: 1990-11-16
Granted: 1997-08-19
Abstract: An operating string (OS) has upper and lower wipers (45), (26) with external seals thereon releasably connected to the operating string (OS). A lock arrangement (98), (210d), (230), (234), (235), (91b) prevents premature release of the upper (45) and/or lower (26) wiper by mechanical force, but is responsive to fluid pressure in the operating string (OS) to first release the lower wiper (26) from the operating string (OS) prior to release of the upper wiper (45). The upper wiper (45) cannot be released from the operating string (OS) until the lower wiper (26) has released from the operating string (OS). Seals (210), (217), (218), (45a), (45b), (45c), (45d), (231), (232) are provided to close off communication between the operating string bore (21) and the external wiper seals (29), (46b') to confine the pressure present in the operating string(OS) in a manner to assure release of the wipers (45), (26) as and when desired and in a sequence as may be desired. The wipers (45), (26) are each connected to the operating string (OS) to accommodate relative rotation therebetween to further reduce the possibility of malfunction or improper functioning in releasing the wipers (45), (26) and to permit the operating string (OS) to be manipulated without releasing the wipers prematurely.

Title: Dark current and defective pixel correction apparatus
Inventor: SUDO FUMIHIKO
IPC: H04N5/361
Filed: 1991-03-12
Granted: 2001-07-10
Abstract: A dark current correction apparatus eliminates a dark current signal component or components from an output signal of an imaging device having an array of pixels. The apparatus includes an A/D converter for digitizing the output signal, and a memory for storing level data of the digitized signal while exposure of the imaging device is controlled to be at a zero level or a uniformly illuminated level, according to whether dark current correction or white current correction, respectively, is to be performed. A dark current correction signal former generates a dark current correction signal or signals from data read out from the memory. The dark current correction signal or signals are applied to a correction circuit which processes an output signal produced by the imaging device during normal imaging operation in accordance with the correction signal or signals in order to eliminate the dark current signal component or components from that output signal.

Title: Twist lock window regulator pivot pin
Inventor: ACCIACCA ALLAN C
IPC: E05F11/44
Filed: 1992-01-17
Granted: 1995-06-13
Abstract: A twist lock pivot pin is provided for rotatably connecting a lift arm of a cross arm window regulator mechanism for a vehicle window to a support panel.  The lift arm has a non-circular through opening and the pivot pin, which is rotatably supported by the support panel, is provided with a complementary shaped non-circular head which is insertable through the non-circular opening in the lift arm.  The head of the pivot pin is undercut to define a neck which engages a side surface of the non-circular opening in the lift arm when the pivot pin is rotated 75 to cause sections of the head to overlie the lift arm to lock the lift arm to the support panel against movement axially of the pivot pin.  A counterbalance spring then biases the neck of the pivot pin into engagement with the lift arm.
Patent CA-2061455-C (CA)
Inventor: MENARD ROGER
IPC: E05C1/12
Filed: 1992-02-18
Granted: 1996-12-10
Abstract: Ce dispositif d'embrayage mécanique à validation électrique oblige une opération manuelle supplémentaire afin de permettre à la partie électrique de fonctionner sous un très faible courant. Ce système, utilisé dans une serrure, comprend un boîtier dans lequel se retrouvent la serrure, les piles, le circuit électronique et le mécanisme d'embrayage ci-haut nommé. Ce dernier est formé d'un cylindre fixé au boîtier dans lequel une tige cylindrique peut tourner librement mais qui peut agir en translation de façon limitée, d'une part par une buté fixe et d'autre part par une buté mobile agissant comme premier mécanisme de blocage. Cette dernière recule lorsque la tige est tirée et elle peut être bloquée dans cette position par une dent, appartenant à un levier qui pivote sur un axe et qui cherche à s'approcher de la buté mobile lorsque cette dernière recule, constituant ainsi le deuxième mécanisme de blocage. Mais le levier peut être empêché d'avancer par la plaque mobile d'un petit relais si le système n'est pas validé. Si validé, la dent empêche la buté mobile de bouger, permettant ensuite à la tige d'avancer pour faire la jonction avec le reste du dispositif à embrayer. Un bouton supplémentaire permet l'embrayage manuel lorsque désiré pour, par exemple, barrer la porte en sortant, sans avoir à actionner le système électrique.

Inventor: BREUNING JOERGEN ILLNER
IPC: E04B5/48
Filed: 1991-09-30
Granted: 2004-09-14
Abstract: The invention presents a technique to development of plane hollow reinforced concrete floor slabs with two-dimensional structure.        Constructions developed by this technique will widely and with considerable profit replace conventional floor structures. The technique makes it possible to chose higher strength and stiffness, less volume of materials, greater flexibility, better economy or an arbitrary combination of these gains. The technique makes it possible to create a total balance between bending forces, shear forces and stiffness (deformations), so that all design conditions can be fully optimized at the same time. The technique presents a distinct minimized construction, characterized by the ability that the concrete can be placed exactly where it yields maximum capacity. The technique offers unusual profits compared with the conventional compact two-way reinforced slab structure: less volume of materials (concrete 40-50 %, steel 30-40 %); 100-150 % higher strength; up to 200 % higher span. The technique is suitable for both in situ works and for prefabrication.
