Patent EP-0213325-A3 (EP)
IPC: B60T13/563
Filed: 1986-07-05
Abstract: A tandem brake booster (10) having a first wall (24) and a 
second wall (28) which move in opposite directions in re­
sponse to a pressure differential created by allowing air to be 
communicated to a control chamber (26) while vacuum is pre­
sent in operational chambers (20) and (30). As wall (28) moves 
straps (124...124 N ) pulls an annular projection (32) to combine 
the force produced in the second wall (28) with the force prod­
uced in the first wall (24). As the operational force is transmit­
ted into push rod (56) from hub (34), sleeve (37) prevent the 
reaction disc (50) from being extruded into passage (40) and 
as such, the reaction force is carried into plunger (64) to pro­
vide an operator with an indicator of the operation of the brake 
booster (10).

Title: Fluid handling apparatus and method
IPC: G01N35/02
Filed: 1986-01-24
Abstract: A fluid handling system is described wherein a small fluid volume (16) is placed on a reversibly-deformable support (12), which can be deformed to form a cavity. As the fluid clings to the surface of the support, it is physically agitated and mixed as the support is deformed. The deformable support can be utilized to provide fluid containers of varying sizes, to accommodate different fluid volumes and as a transport mechanism to move fluid from one location to another.

Patent EP-0214738-A3 (EP)
IPC: H01G11/24
Filed: 1986-07-25
Abstract: Improved activated carbon electrodes are disclosed, 
which electrodes have increased charge storage capacity. 
Such improved electrodes are incorporated into energy 
storage devices such as electrical double layer capacitors. The 
improved charge storage capacity is due to the adsorption of 
polyoxometalate compounds into the activated carbon, 
which compounds are capable of reversible redox reactions 
and so provide a secondary charge storage mechanism 
without decreasing the charge storage ability of the activated 
carbon.

Title: Tamper-evident structures
IPC: B65D55/02
Filed: 1988-08-04
Abstract: The invention relates to a laminated tamper-evident structure which exhibits an irreversible colour change upon delamination. The structure includes a laminate of at least two layers (10,12) capable of generating a colour by a light interference and absorption phenomenon that requires direct and intimate contact between an adjacent two of the layers. The strength of attachment among the layers of the laminate is such that the laminate can be uniformly and reliably peeled apart at the interface between the adjacent two layers. An overlying flexible strip (14) of transparent or translucent material is adhered to the laminate to facilitate the peeling operation. Upon peeling apart the laminate, the generated colour is irreversibly lost, thus providing evidence that the structure has been tampered with. The structure can be incorporated into a variety of closable articles or products to provide evidence of opening or tampering.

Patent EP-0349783-A3 (EP)
IPC: G01B5/00
Filed: 1989-06-08
Abstract: Measured temperatures can be used for the purpose of compensating thermally induced dilatations, e.g. on machine tools. Compensation methods known to date satisfy themselves with a few temperature measurement points. However, entire temperature fields in the components are responsible for the thermal dilatations. Consequently, said compensation methods are unsuitable in the case of rapid variation in rotational speed, in particular when thermally induced dilatations are to be measured on moving components. Better results are obtained if for the purpose of compensation use is made of a measurement signal which is proportional to the expansion of the component. In addition, in accordance with Figure 4 it is possible to compensate angular displacements of spindles (S) such as occur, for example, with the main spindles of lathes. The tool or workpiece position can be directly corrected by attaching resistances on linear scales. <IMAGE>

The power lead element is a stranded conductor having one end connected to the appertaining terminal element and the other end directly connected to the contact element. Therebetween, a stranded conductor is conducted from one side of the coil to the other through a transverse bore in a coil member flange. In this way, the stranded conductor and, thus, and the load circuit is well insulated from the winding and, moreover, the power lead element requires no space in the actual winding space, simplifying the assembly thereof as a result.

Abstract: A learning pattern is classified into a plurality of 
patterns by a classifying means (102). The result of the 
classification, as well as the representative features 
quantity calculated by a representative feature quantity 
operating unit (103), are stored in a dictionary storing 
unit (104) in respective regions. Upon recognition, after 
feature quantities of unknown input patterns are extracted 
from a feature quantity extracting unit (101), a 
similarity operating unit (105) arithmetically operates 
the similarity between the input pattern and respective 
learning patterns for respective regions. The point 
accumulating means (106) searches a dictionary storing 
unit (104) and accumulates points corresponding to a rank 
for respective learning patterns included in class having 
the upper rank from the highest to a lower similarity for 
respective regions. The recognition result candidate 
outputting unit (107) outputs the recognition result 
candidate in accordance with the order of the higher 
accumulated point for the learning pattern. Therefore, 
the present pattern recognition can decrease the memory 
capacity of the dictionary and the number of the 
calculations.

Abstract: The system operating in accordance with the principle of chain synchronization, comprising a central station (Z) having several two-core primary signalling lines (ML), to which a plurality of detectors (Mn) are connected in the form of a chain which are regularly cyclically activated from the central station (Z) and are interrogated for their respective analog detector measurement value, in each case uses detectors (Mn) which exhibit a voltage measuring device (MU) which monitors the applied line voltage (UL), a subsequent logic circuit (VL) with associated sensor part (S), a subsequent control device (St), an energy accumulator (C) and a switching transistor (T). The logic circuit (VL) is essentially formed by a microprocessor which can be connected and disconnected. According to the invention, the microprocessor is switched into a current-saving standby condition and switched on again in dependence on particular switching criteria which are specific for the hazard signalling system, a required start-up time (tan) being ensured for the microprocessor. For example, the microprocessor is switched to the standby condition in dependence on a particular line voltage (disconnecting voltage UAB=UR) and switched on again with the presence of another predetermined line voltage (connecting voltage UAN=US) so that the detector is activated after a particular start-up time (tan=ts). <IMAGE>
