Abstract: The invention refers to a solution for the reactor block of a sodium-cooled fast reactor, fitted with an inner cylindrical vessel. This forms the mechanical structure for hydraulic separation 7 between the primary sodium hot header 2 and the cold header 3. The hot header is located in the area above the core, and the cold header, having a larger volume and an an­nular shape, is located all around the hot header. According to the invention the primary pumps and inter­mediate exchangers 8 are immersed in the cold header 3. The intermediate heat exchangers 8 are of the straight tube bundle type, with primary sodium outside the tubes, and they are hydraulically connected to the hot header by a transverse duct 13, solid with the inner cylindrical vessel 7, and mechanically sealed where it interfaces with the exchanger. This mechanical sealing system is made as close against the exchanger as possible, so that the component is removable.

Abstract: Subgingival plaque samples can be analyzed for the presence of the trypsin substrate N-benzoyl-DL-arginine-2-naphthylamide (BANA) in order to make a clinical diagnosis of periodontal disease. The solid phase test utilizes enzyme sensitive reagents adsorbed separately onto two elements. The sample is added to one element, the second element contacted therewith and water is added to initiate the reaction. The resulting analysis is complete within thirty minutes. Positive tests indicating periodontal disease-causing organisms are determined by a color change on the element containing the Fast Black K salt color developer. The test provides a stable, readable, permanent record which can be included in the patient's dental records.

Abstract: A learning control system for controlling the throttling of an internal combustion engine (1) includes a step motor (9) for operating the throttling lever (4) of a fuel supply device (2) which supplies fuel to the internal combustion engine (1). Each time the number of steps for driving the step motor is incremented, the rotational speed of the engine (1) is detected and compared with a preset maximum engine rotational speed. When the rotational speed of the engine (1) reaches the preset maximum engine rotational speed, the number of steps is stored as the number of steps for driving the step motor (9) at the time the accelerator pedal (11) is fully depressed.

Abstract: A closed-loop attenuator for an FM stereo receiver provides attenuation to a L+R audio signal in a controlled and predictable reaction to an ultrasonic noise (USN) voltage presented to an input amplifier (10). This is accomplished through a closed-loop circuit configuration including a multiplier (16) which modulates the current output of the input amplifier (10) in accordance with the output of a master differential amplifier (18) and supplies the modulated current to a gain stage (14) connected to the input of the master differential amplifier (18). The output of the master differential amplifier (18) is mirrored by a slave differential amplifier (20) which applies the actual audio signal attenuation. The closed-loop configuration confines this linear control action to a very narrow range. Outside of this range, the circuit provides either full attenuation or no attenuation.

Abstract: A probe head (10) for orientating a probe relative to a head of a coordinate measuring machine, has a support (12), a rotor (14) rotatable relative to the support (12), and a swivel (18) rotatable relative to the rotor (14). The rotor (14) and swivel (18) are mounted for rotation through a series of discrete, and repeatable rest positions. The relative orientation of support (12), rotor (14) and swivel (18) is detected by an indicating mechanism comprising a printed circuit board (34) having a series of electrical conductive elements (36) and (38) and a contact arm (40) mounted for rotation over the conductive elements on the circuit board (34). When the electrical contacts (42) to (46) come into register with the conductive elements (36) on the circuit board (34) a pulse is transmitted to a micro-processor (50) which determines the relative orientation of e.g. the support (12) and rotor (14); this is shown on an LCD (52). The micro-processor may also provide instructions (on the LCD (52)) indicating in which direction the rotor (14) should be moved in order to attain a predetermined position stored in a memory of the micro-processor; an indication is provided on the LCD (52) that such a predetermined position has been attained.

Abstract: For on-chip self testing, a first data register (10) performs storage or transfer of data, operates in a scan mode or generates pseudo-random numbers (PRN), and a second data register (60) performs storage or transfer of data, operates in a scan mode or performs signature analysis. Data initialisation of the registers occurs automatically when operating in a test mode. Each stage (50,...,100,...) of each register includes a mode controller (33,83) which in the data mode passes data from a data input transmission gate (22,72) to a storage flip flop (38,90), or initialisation data from an initialisation transmission gate (20,70) at the beginning of a test mode. Also during the test mode, data output from each stage is fed back through exclusive-OR gates (40,42,90,92) and a transmission gate (32,82) to a first one of the stages (Stage A). Data and test mode are selected by a test enable signal applied through conditioning logic (12,14,16,18,24,26; 62,64,66,68,74,76) to each stage.

Abstract: Buffer control apparatus for making a timing control for reading and writing data to and from a buffer used in for example a hard disk device. A write pointer specifies a write address of a buffer and a read pointer specifies a read address. A comparator compares the values of the pointers and when an equal signal is output from the comparator, a discriminator identifies one of the write and read pointers which has caught up with the other. Writing to the buffer is inhibited when the write pointer has caught up with the read pointer and reading from the buffer is inhibited when the read pointer had caught up with the write pointer.

Abstract: The center of a collet (10) having a plurality of individual gripper members (32) resiliently spaced apart in an annular array and operated on by a frustoconical surface (14) can be adjusted by displacing some of the gripper members more than others of said gripper members parallel to the axis (20) with which both the annular array and the frustoconical surface are nominally concentric. This causes the frustoconical surface (14) to produce greater radial displacement of some of the gripper members (32), thereby shifting the center of the collet (10) transverse to the above-mentioned axis (20).

Abstract: In an optical heterodyne or homodyne receiver an optical system (140) is used in which the local oscillator beam (L) is combined with the signal beam (S). Simultaneously, these beams are split into orthogonally polarized sub-beams. For this purpose the optical system (140) comprises polarization-sensitive beam-splitting layers (141a and 141b) and neutral beam-splitting layers (142a and 142b) which function as beam-combining elements. In order to align the directions of the exit sub-beams of the signal beam (S₁₁, S₁₂, S₂₁, S₂₂) and the local oscillator beam (L₁₁, L₁₂, L₂₁, L₂₂), the angles (α,γ,β, δ) enclosed by the beam-splitting faces are chosen to be such that two angles located opposite each other have a combined magnitude of 180 o . This is realised by providing the layers (141a, 142b and 141b, 142a) on side faces of one prism (140a, 140b).
