Patent EP-0265984-A1 (EP)
Inventor: RAAYMAKERS WILHELMUS PETRUS MA
IPC: G11B7/24082
Filed: 1987-10-05
Abstract: A record carrier (40) comprises a radiation-sensitive layer (43) upon a disc-shaped substrate (42) and is provided with an information-recording area arranged in accordance with a spiral-shaped or concentric pattern of preformed tracks (41). The track exhibits a track modulation in the form of a radial wobble whose frequency is modulated with a position-information signal (Ip). Further, an apparatus (1) is disclosed for forming the track pattern during the manufacture of the record carrier (40). When an information signal (Vi) is recorded on the record carrier (40) and the recorded signal is read an FM demodulation device (60) recovers the position-information signal Ip from the variations in the scanning beam (54, 54a) produced by the track modulation. Moreover, a clock signal for the purpose of scanning-velocity control is recovered from these variations in the scanning beam.

Abstract: Apparatus for transferring components, particu­larly rod control cluster elements for a nuclear reactor, to and from containers, particularly fuel assemblies, with the aid of a movable carriage (6) containing compartments (10,14) for receiving at least one fuel assembly and (12) at least one rod control cluster element. The carriage is mounted on tracks (4) and carries an abutment member (60) arranged to cooperate with stops (58) which delimit respective positions of the carriage along the tracks. When the carriage is at least in some of its positions, a respective compartment is located directly below a vertically movable gripper (20) which is operable for gripping a rod control cluster element. In order to allow the carriage to have more than two positions, there is provided a movable stop (50) which can be lowered to permit the carriage abutment member to move therepast and raised to be contacted by the abutment member. Movements of the car­riage and gripper are controlled by means of pushbuttons located at a station accessible to an operator and via a data processing system which is responsive to actuation of the pushbuttons to effect the indicated operation.

Abstract: A surface acoustic wave filter comprising: a first bidirectional ID transducer (5) of symmetrical form; a second ID transducer (1) acoustically coupled with the first transducer and comprising two parts (1A, 1B) each of which parts is in the form of one half of a respective bidirectional ID transducer (9 or 11) of symmetrical form, the two parts being positioned with respect to one another and the first transducer so that when respectively excited by corresponding signals of different phases they co-operate to produce a unidirectional acoustic signal propagating towards the first transducer from one side thereof; and a third transducer (3) acoustically coupled with the first transducer and comprising two parts (3A, 3B), each of which parts is electrically connected in parallel with a respective one of the two parts of said second transducer, and each of which parts of the third transducer is effectively in the form of the mirror image about the centre line (7) of the first transducer of the other half of the bidirectional transducer whose one half constitutes the part of the second transducer with which it is connected. The invention provides a filter of intrinsically low insertion loss without the use of a cross-over structure as is required in known forms of low loss filter using unidirectional multiphase ID transducers.

Abstract: A data processing machine which is controlled to produce graphical output from stored sets of data. The data sets may be stored in the non-uniform manner. The machine is controlled to determine column boundaries in each row of a data set and then to determine column boundaries in each row of a data set and then to determine which rows of the set have missing items. Data sets can then be reformatted as graphs or similar representations. The machine takes away the constraint on users to accurately enter data items into specific slots in a table or date set.

Abstract: An immunoadsorbent material for removing IgM and IgM-complexes from biological fluids is prepared by covalently binding anti-IgM antibodies to a solid-phase silica matrix. It has been found that reacting hydroxyl-derivatized silica in the presence of cyanogen bromide with the anti-IgM antibodies provides a particularly stable, high-capacity immunoadsorbent. The immunoadsorbent material may be employed in a column for therapeutic treatment of various disorders, such as primary biliary cirrhosis.

Abstract: A gas torch comprises a body with at a first end adjuster valves for connection to fluid supplies and at a second end a torch tip. At the first end there is a support from which the body extends to the tip. The body is made up of sections of rigid tube articulated and connected to each other by articulation and fluid passage connection devices. These ensure continuity of fluid circulation between the sections of tube. The sections of tube near the support are articulated to the support by articulation and fluid passage connection devices enabling them to be connected to the valves. Maneuvering means are articulated to the supports and to at least the sections of tube near the support so as to enable remote displacement of the tip. The tip is supplied with fluid by some at least of the articulated sections of tube constituting the body.

Abstract: An accelerator for a fishing jar is disclosed. The accelerator includes front (11), compression (15), rear (23), and air (25) chambers. These chambers insure that the pressure of the fluid in the compression chamber is substantially independent of the temperature of the fluid and the hydrostatic pressure of the well. These chambers also insure that the high pressure seals of the compression chamber are lubricated on each side of each seal. The accelerator also insures that a threshold upward force which is proportional to the hydrostatic pressure must be applied to the drill string before the fluid in the compression chamber begins to be compressed, thereby providing an accelerator that has a higher maximum load in deep wells.

Abstract: A vehicle has first and second drivers' seats (18, 18a) and a control console (10), the control console carrying a plurality of individual controls and display means. The drivers' seats are in side-by-side relation. Pivot means (19) carry the control console to permit the console to pivot between at least a first position facing the first driver's seat and a second position facing the second driver's seat. Thus, two drivers may operate the vehicle from the same control console in alternating manner. Typically, releasable locking means provide retention of the control console in either of the two positons described above, and also in an intermediate rotating position in which the control console faces between the two seats. Also, cable means may communicate with the control console, the cable means extending through the pivot means for communication with the rest of the vehicle.

Abstract: A bone clamp (10) and method of use is described for clamping damaged or fractured bones (14). The clamp comprises a hooked or barbed pin (22) which is inserted through a hole (12) in the bones (14) to be clamped. The hook (22) springs out to rest against the far side (20) of the bone. The shaft of the pin (16) protrudes from the near side of the bone and has conical shaped protrusions (18) whose larger ends (48) face torward the hook. A unitary clamping button (26) having a central bore (28-30) smaller than the larger ends (46) of the conical protrusions (18) is slipped over the exposed shaft (16) and forced over the protrusions (18). The protrusions (18) and/or the button (26) deform to allow passage of the button (26). Once the button (26) is past a protrusions (18) the deformed parts spring back to their original shape and the button (26) cannot be retracted. An automatically locking ratchet-type clamping action is obtained and installation of the button (26) may be made with one hand.
