Patent GB-2241780-A (GB)
Title: Measuring distance
Inventor: NOSE NORIYUKI
IPC: G01D5/38
Filed: 1991-03-08
Abstract: A device for measuring the relative position of two relatively moving objects includes a diffraction grating (GS) on one object and a measuring head (MH) on the other object (SR), which includes a second diffraction grating (GF1 and 2), a light source (LD) and a photo-detecting system (PD1-4). Two beams (LO1 and LO2) are projected upon two parts of the. second diffraction grating so that different diffraction orders are directed to the same point on the first diffraction grating (GS) and are thereby diffracted along a common path and mutually interfere. The photodetecting system (PD1-4) determines the position from cyclical variations in interference produced by relative movement between the two gratings. Polarising beam splitters (MK21-23) may produce beams out of phase by steps of 45 DEG . In other embodiments a single grating receives two beams at different angles produced by a double refracting prism, and a single grating splits one beam into opposite diffraction orders which are reflected back through the grating and recombined. <IMAGE>

Patent GB-913867-A (GB)
IPC: G21C7/00
Abstract: 913,867. Nuclear reactors. BABCOCK & WILCOX Ltd. Jan. 27, 1959 [Jan. 27, 1958], No. 2735/58. Class 39 (4). In a nuclear reactor of the kind having a reactor core with fuel channels through which a fluid coolant passes, neutron-absorbing material distributed within the core to effect flux-flattening is so arranged that the thermal neutron flux during operation in at least some of the channels has a peak value at a location along the length of the channels between the coolant inlet and the mid-point of the channel and spaced from the mid-point by a distance of at least 10% of the length of the channel, the arrangement being such that a higher bulk coolant temperature at the coolant outlet from the core is obtained than if, the conditions being otherwise similar, the heat flux were determined by a thermal neutron phase symmetrical in relation to the channels and varying along their lengths in cosine manner. It is explained that this distortion of the neutron flux reduces the maximum temperatures at the centre of the fuel and at the surfaces of the fuel cans; in fact these temperatures may be made substantially constant over most of the length of the fuel channel, and the maximum gas outlet temperature can thus be increased. The desired flux is achieved by appropriate distribution of neutron absorbing bodies in the core, possibly assisted by the distribution of aged fuel elements. Fig. 2 shows a crosssection of a quadrant of a reactor core comprising graphite columns of square crosssection provided with central fuel channels 5; the corners of some of the columns are shaped to provide two further sets of channels 29, 30, the channels 30 containing the usual control rods and the channels 29 containing the neutron absorbing bodies which produce the required flux distribution. As shown in Fig. 4, the neutron absorbing bodies comprise elements 31 of the same length as fuel elements and which can be handled by the fuel-loading gear; each element comprises a column assembly of collars 32 which are of mild steel if neutron absorption is required and of graphite otherwise, the absorption being adjusted by replacing a steel collar by a graphite one or vice versa.

Filed: 1994-02-11
Abstract: A computer based logging device, including dual-axis accelerometers and capable of measuring forward and lateral accelerations, is installed in a road vehicle. Using acceleration data which has been measured over a period of time, the device classifies the driver into one of several groups, each of which is associated with a different level of accident risk. The device has a display panel to indicate to the driver the group to which he or she is currently assigned and advice on how to make his or her driving safer. Each driver is identified by a separate programming means, to be applied to the logging device before driving the vehicle. The programming means is also used to transfer the results from the logger to a remote database, where accident risk and driver group parameters are determined.

Title: Method of determining the start and the end of an automatic braking process
Inventor: STEINER MANFRED
IPC: B60T7/12
Filed: 1994-07-28
Abstract: In a method for determining the start and the end of an automatic braking process, an automatic braking process is triggered when the actuation speed of a brake pedal exceeds a threshold value. The triggering of the automatic braking process is optimized by changing the threshold value as a function of the driving state, e.g. the speed of the vehicle when the brake pedal is actuated and, independently thereof, the position of the brake pedal. In addition, various criteria are described for terminating the automatic braking process as a function of the actuation force of the brake pedal, of the speed of the vehicle and of the pedal travel.

Abstract: Apparatus for separating and sequencing individual articles, for example seeds, comprises a perforated drum (3) which in use is rotated in the direction of the arrow (4) by a motor (5). The surface of the drum passes in sequence over a first chamber (7) in which a vacuum is maintained and a second chamber (8) in which a super-atmospheric pressure is maintained. A bulk supply of articles to be sorted is maintained in a trough (12) and individual articles are removed from the bulk supply by being attracted against the perforations by the vacuum existing in the first chamber. The perforations come into register with the second chamber (8) one at a time so that a sequence of individual articles is formed in chute (15). Counting means are provided to count the individual articles. The counting means may include means of determining the size of individual articles and means for comparing the measured size with acceptable size standards so that articles falling outside of acceptable standards are not counted. Fluorescence and/or colour detectors may also be included to determine whether or not articles have acceptable characteristics. The invention is particularly useful for the counting and packaging of seeds.
