Patent GB-2128104-A (GB)
Title: Educational aids games and playthings
Inventor: BARNWELL GEORGE DERRICK
IPC: A63F9/10
Filed: 1983-10-07
Abstract: The invention relates to educational aids, games and playthings. With such items as conventional jigsaw puzzles, there is reliance on the presence of interlocking nodules and recesses and the cutting of the faces from a large sheet is relatively expensive. The nodules are easily damaged during repeated assembly and dismantling of the puzzle. It is known that so-called magnetic rubber can be utilised for itself holding effect on an appropriate board but such material applied to educational aids, games and playthings has not proved readily acceptable because of the cost of the board and the use of sheet foil or metal which can cause injury to the user. The object of the invention is to avoid the above disadvantages, which objective is met by a construction of educational aid, game or plaything comprising a number of pieces of magnetic rubber collectively capable of careful juxtaposition into abutting side-by-side relationship to form a coherent pattern on a support surface capable of holding the pieces in position by magnetic attraction, said support surface being formed as a non-metallic board having a coating formed from or including ferromagnetic particles.

Title: Pattern-recognizing self-tuning controller
Inventor: KRAUS THOMAS W
IPC: G05B13/02
Filed: 1985-03-25
Abstract: Measured characteristics including at least one error signal peak, derived from the differences occurring over time between the values of a process controlled variable (14) and a desired set-point level (22), are used to identify the behaviour pattern of the error signal (32) so that an operating parameter of the controller can be changed to minimize process recovery time whenever the process is subsequently disturbed or an abrupt change is made to the set-point level e.g. by a disturbance (26). A PID controller (42) may be used, the PID coefficients being calculated in accordance with prescribed relationships determined by adapter (34) and based on damping, overshoot and time period characteristics of the error signal and initialising signals (46). A user-specified noise threshold may be entered (46) to reduce the possibility of detecting a noise peak as a true error signal peak. In a pre-adapt mode the controller automatically determines the initial values of the PID coefficients, the noise threshold, and the approximate time scale of the process. <IMAGE>

Title: Fluid gauging system
Inventor: CLINTON PETER
IPC: G01F23/26
Filed: 1986-03-26
Abstract: An aircraft fuel gauging system has a capacitance level probe (6) mounted in a fuel tank (5) that receives an alternating signal from a drive unit (2). The output of the level probe (6) is connected to two diodes (7 and 8) one of which is connected in series to earth and the other of which is connected in the opposite sense to a measuring unit (3). The measuring unit (3) includes a signal conditioning unit (32) which is switchable between operating as a d.c. current to voltage amplifier and a d.c. voltage amplifier by switching a resistor (35) out of or into series connection with the diodes. A constant current source (50, 51) backs off the current from the probe when the tank is empty. Periodically, the supply of signals from the drive unit (2) is interrupted and the conditioning unit (32) is switched to operating as a d.c. voltage amplifier, the measuring unit (3) measuring the voltage drop across the two diodes (8 and 7) caused by current from the constant source (50, 51). The current from the constant source (50, 51) may be increased when the resistor (35) is connected in line such that the current through the diodes is substantially the same as the mean current during a.c. operation. The measuring unit (3) may provide an indication of temperature derived from the voltage drop across the diodes (7 and 8). <IMAGE>

Title: Vacuum-operated brake power booster
Inventor: FELLINGER ROLF
IPC: B60T13/575
Filed: 1986-05-16
Abstract: In a vacuum-operated brake power booster, a rubber reaction disc (30) between a valve piston (16) mounted in a control housing (2) and a push rod (29) co-operating with a piston of a master cylinder (not shown) is shaped in the form of a truncated circular cone or part of a sphere with an edge of the rubber reaction disc (30), extending radially outwardly in the form of a flange, abutting a step (b) of a recess (24) of the control housing (2). The recess (24) of the control housing (2) also has a funnel-shaped portion (13) which is filled by means of the second (truncated-cone) portion (d) of the rubber reaction disc (30). The truncated cone shape of the rubber reaction disc (30) permits the use of a very soft elastic material, the volume increase of the rubber reaction disc (30) caused by differences in temperature being compensated in that the material flows into the gap between a disc (6) and the rubber reaction disc (30), since the large end face of the rubber reaction disc, firmly abuts on the push rod (29) of the master cylinder piston, which push rod is preloaded by means of a spring. A reduction of the gap between the disc (6) and/or the valve piston (16) and the rubber reaction disc (30) has the extremely favourable effect that the response or lost travel of the brake power booster is reduced. <IMAGE>
