Title: Window stop
Inventor: THORNHILL GLENDON
IPC: E05C17/60
Filed: 1994-01-19
Abstract: "Devices for partially opening and closing horizontal and vertical sliding windows are obstructive, complicated and difficult to operate.        Permanent or difficult devices can be obstructive in a quick escape during the event of a disaster, e.g. bars.  In this invention, a track elevated on two stand-offs are mounted on a frame parallel to the opening side of a sliding window; a slidable bracket embracing the track with an extended arm; the arm permits limited backward movement of the window; a bolt secured in a recess in the bracket body contains a pin, a spring and a ring for biasing and retracting the bolt out of the slots in the track; the slots permitting movement of the bracket in either direction on the track so that the window can be permanently closed or partially closed or opened."

Title: Continuous casting apparatus for ingots to be rolled
Inventor: SCHNEIDER WOLFGANG
IPC: B22D11/08
Filed: 1994-03-04
Abstract: A continuous casting billet consists of a mould with a shaping attachment (1) and of a die (3) which closes the mould (2) at the lower end in the starting condition and which, from the shaping attachment (1), receives a metal melt directed in the vertical direction towards the die. The die (3) consists of a block which is shaped approximately like the mould and which is provided with a substantially tub-shaped indentation (5) delimited by a continuous edge (4). The indentation (5) comprises at least one raised portion (6) arranged symmetrically relative to the central axes (7, 8) of the die. The side walls of the continuous edge (4) and the raised portion (6) are inclined towards the indentation (5). The invention provides increase of safety during initial casting, improves billet stability and greatly reduces the occurrence of billet base deformation and billet base scrap.

Abstract: An accumulator (30) for an implantable infusion system employs a pair of separated diaphragms (47, 52) movable in unison by a transfer fluid disposed therebetween. A drug chamber (41) received infusate in metered amounts through inlet (42) and dispenses the contents as a function of a toggled valve operation. During filling, the first diaphragm (47) deflects upward and by pressure transfer causes a corresponding deflection in the second diaphragm (52). The second diaphragm (52) is biased by springs, gas under pressure or the like. Hence, when inlet valve (26) closes and outlet valve (28) opens, the pressure differential cross second diaphragm (52) causes downward deflection and fluid flows through outlet (44). No mechanical stops are needed in chamber (41) for the first diaphragm (47) since its movement is controlled by the pressure differential across the second diaphragm (52).

Title: Method and apparatus for operating a neural network with missing and/or incomplete data
Inventor: KEELER JAMES DAVID
IPC: G06N3/04
Filed: 1993-11-19
Abstract: A neural network system is provided that models the system in a system model (12) with the output thereof providing a predicted output. This predicted output is modified or controlled by an output control (14). Input data is processed in a data preprocess step (10) to reconcile the data for input to the system model (12).  Additionally, the error resulted from the reconciliation is input to an uncertainty model to predict the uncertainty in the predicted output. This is input to a decision processor (20) which is utilized to control the output control (14). The output control (14) is controlled to either vary the predicted output or to inhibit the predicted output whenever the output of the uncertainty model (18) exceeds a predetermined decision threshold, input by a decision threshold block (22). Additionally, a validity model (16) is also provided which represents the reliability or validity of the output as a function of the number of data points in a given data region during training of the system model (12). This predicts the confidence in the predicted output which is also input to the decision processor (20). The decision processor (20) therefore bases its decision on the predicted confidence and the predicted uncertainty. Additionally, the uncertainty output by the data preprocess block (10) can be utilized to train the system model (12).

Title: Lift with a lift cage
Inventor: FERRARIO RENATO
IPC: B66B11/02
Filed: 1995-07-31
Abstract: In a panoramic lift, a roller placard (7) is provided, which is fastened at one end at a reeling and unreeling device (9)  in the shaft foot (11) or in the shaft head (14) and at the other end at the cage underside  (12)  or at the upper cage side (15)  and which is thereby reeled and unreeled in the lower or upper shaft region (13, 16) during the travelling of the lift cage (5).     The reeling and unreeling device (9)  is mounted in the shaft foot (11) or in the shaft head (14) to be easily exchangeable as well as alignable horizontally and vertically and contains a rotating drum (8), which carries the roller placard (7) and is biassed in reeling-up direction  relative  to  its  rotational  axle  by means  of spiral springs.  Roller blind lifts (A, B) are secured against blocking of the rotating drum (8)  in both directions of rotation.   The roller placard (7) is preferably a foil or a fabric of a tear-resistant and bending-resistant synthetic material which can also be printed on in colour, but is not combustible or only combustible with difficulty. It achieves the greatest attention due to its permanent presence and its constant reeling and unreeling movements.  Special light effects result through  particular  choice of material  in  the case of  the roller placard (7), by the use of lasers and coloured or polarised light or by the use of specially coated glass for the cage (5) and the lift shaft (4).
