Title: Correction of errors in autopilots
Inventor: BOOTH THOMAS BRINDLEY
IPC: G05D1/00
Filed: 1988-05-05
Granted: 1996-01-09
Abstract: A system (1) responds to inputs (2) in parallel with a state estimator (4).   The controller (6) provides the inputs (2) in response to ordered state inputs (14) and state estimator inputs.   An external disturbance vector (f) affects the system (1) so that the observed values of the state variables are not the same as the estimated values. The estimated and measured values are compared (8) to give an error signal (9).   The error values are fed to an Ordered State Corrector (11) which computes the error that the ordered state variable would have in the steady state and applies it in the opposite sense to increment the input ordered state (14).   If more than one state variable is to be corrected, the correction is applied directly to the control inputs using Multi-State Correction, in which the steady state errors are used to find the control inputs which would cause the errors and then a correction is applied to the control inputs.

Abstract: Abstract of the Disclosure Fluorine-generating electrolytic cells A fluorine generating electrolytic cell comprises a base (12) and cooling coils (24) for cooling the electrolyte, the cooling coils (24) being displaced from the base (12).  A layer (10) of plastics material such as PTFE is disposed on the base (12) to electrically insulate the base (12) and the layer (10) is held against the base (12) by means (14-22) bridging the space between the cooling coils (24) and an upwardly presented face (9) of the layer (10).  By using the cooling coils (24) in holding the insulating layer (10) in place, the need to make changes to the cell vessel is avoided and installation and removal of the layer (10) is relatively easy and inexpensive.  In addition, by using an insulating layer (10), all of the electrolyte is molten with the advantage that a smaller temperature gradient through the depth of the electrolyte results, which leads to improvements in mass transfer.

Abstract: CE12r Abstract of the Disclosure An improved TDMA radiotelephone cellular communication system employs an improved cell site scan monitoring technique. The technique includes monitoring radiotelephone calls, and tracking and recording their signal qualities. The records are used to maintain and determine which frequencies and which time partitions at the base site equipment are being utilized for radiotelephone communication. When a new call assignment is required at a cell site, it is assigned to a time partition of a base site equipment frequency in a frequency prioritized manner such that radiotelephone calls are concentrated within each frequency so as to reduce the number of frequencies carrying radiotelephone calls.

The device  includes  a measuring  head  and  an  apparatus  for  traversing  the measuring head across a photosensitive material attached to the body.  The measuring head measures the intensity of light  reflected  or  dispersed  from  the  photosensitive material.   The reflected or  dispersed  light  is emitted from  and  received  by  diodes  in  the  measuring  head. Electrical  signals  representative  of  the  intensity  of light  traversing  the  photosensitive  material  in  three directions are generated for each of a set of points on the photosensitive material.   The electrical signals are analyzed by computer and converted to stress and strain data which may then be displayed on a plotter or monitor. The method includes traversing the measuring head across the photosensitive material,  detecting  the  intensity of light  dispersed  or  reflected  from  the  photosensitive material  in  three  directions,  analyzing  the  electrical signals  to  produce  stress  and  strain  data  for  the photosensitive material at each point, and displaying the resulting stress and strain data.

The apparatus includes numerous functional blocks (20), a core (30), and a parametric/microinstruction bus (35). The functional blocks include serial (62,66) and parallel ports (68), D/A (54) and A/D (52) converters, and programmable signal processors (300) which serve to process signal data and are connected in any desired manner through a switching matrix (160) located in the core.  The topology of the switching matrix (160) is received via the communications bus (40).  Parameters and microinstructions for the programmable signal processors (300) are sent via the communications bus (40), the core (30), and the parametric/microinstruction (35) bus.  Topological and/or parametric data may be burned into the switch matrix and functional blocks as permanent programmed memory, or held in programmable nonvolatile or volatile memory associated with the core and functional blocks.  Signal data is typically received and transmitted via the serial and/or parallel ports (62,66,68) and via the D/A and A/D (54,52) converters of the apparatus.

Abstract: Nail-type fastener comprising an elongated shank (1) having three symmetrically positioned, longitudinal grooves (4) separated by longitudinal ridges (8) with a cross-sectional arcuate outer side (9), the grooves having flat, concave or cross-sectional V-shaped bottom surfaces (27, 17, 7). The nail has a high-flexured rigidity and high pull grip with comparatively low weight. The fastener or nail is produced starting from a cross-sectional circular nail wire stock which is profiled in two cold-rolling steps. In the first step, the nail wire passes through a first roller trio, the section rollers producing grooves into the nail wire stock. In the second step, the nail wire passes through a second roller trio, whereby a deepening of these grooves into deep grooves is brought about. Thereupon the head and the point are produced at the ends of the shank, the finished nail thereby being separated.

Abstract: A sub-roof for roofs with roofing boards consisting of a plurality rectangular insulating boards (1) overlapping each other in direction of the slope of the roof. Each insulating board has a parallel plane central section (3), integral with a wedge-shaped board section (2) on the ridge side and a wedge-shaped board section (4) on the eaves side, the thickness of which increases towards the middle of the board. The thickness of the board sections (2 and 4) on the ridge side and on the eaves side at their edge towards the central board section (3) is at least equal to the thickness of said central board portion (3) and, when thicker boards are used, reaches said thickness after going through a step (11 and 12). The insulating boards (1) are placed so that they constitute an offset double or multiple covering. Due to the wedge-shaped multiple overlap the rows of insulating boards can be shifted within the longitudinal direction, for example, to adapt to different batten intervals or spacing, whereby the effective insulating layer thickness of the sub-roof does not change noticeably and tightness is not affected.

Abstract: Opening arrangements for packing containers often consist of a pouring opening formed in the packing container wall which is covered by a tear-off cover strip. To faciliate the removal of the cover strip, the same is placed so that it projects with one end portion outside the edge line of the container wall. However, this also increases the risk of unintentional opening. To reduce this risk the projecting end part (6) of the cover strip (5) may be folded about 180 DEG  to lie against the main part of the cover strip, at the same time as the cover strip is provided with one or more moulded portions (9) which make it possible to insert a finger underneath the grip lug (6) and lift the same when the cover strip (5) is to be removed.
