Abstract: Folding eyeglasses include, in combination, a pair of members each having a lens and a half-nosepiece and a half-bridge. Means disposed on the half-bridges afford rotation of the members relative to one another about a vertical axis. A pair of temples are mounted on the respective members, remote from the half-bridges and rotatable about a vertical axis. Each temple has an intermediate hinge dividing the temple into a front part and a rear part rotatable relative to one another about a vertical axis.      Each rear part may be rotated inwardly to contact its corresponding front part. Each lens has a rear surface; each half-bridge and corresponding half-nosepiece extending rearwardly of that rear surface and being provided with a horizontally-extending recess therebetween so that each contacting front and rear part may be rotated into a corresponding recess and the two members may be folded until the half-nosepieces are in proximity to one another.      In the folded position of the members the two recesses form an aperture and the intermediate hinges extend into that aperture.

Title: Method of and apparatus for controlling a process
Inventor: BAILEY GRAHAM
IPC: G05D23/19
Filed: 1996-05-03
Granted: 2005-10-25
Abstract: The present invention relates to a method of controlling an output variable of a process having long dead times and delay times, for example for controlling the interior temperature of an abosrber refrigerator, and also relates to an apparatus for carrying out such a method. The output variable of the process, such as the interior temperature, is sampled and compared with a desired value in order to determine a desired value deviation. In dependence on the determined desired value deviation, a manipulated variable, such as the power supplied to the absorber, is calculated in such a manner that the output variable of the process is brought near to the desired value. After the lapse of a waiting time, a value of the manipulated variable is newly determined. During the waiting time, the manipulated variable is not altered.  The waiting time is calculated on the basis of the difference between the value of the manipulated variable and an earlier value of the manipulated variable. A  controller for carrying out the method comprises a memory for an earlier calculated manipulated variable and a timer which is designed to receive the earlier calculated value of the manipulated variable and the current value of the manipulated variable, to calculate a waiting time from these and, after the lapse of this waiting time, to start a new calculation of a value for the manipulated variable.

Granted: 1998-11-17
Abstract: A method of winding a length of a conveyor belt onto a support structure which is delivered to the location where it is to be used, and then unwound.  The length of conveyor belt is then spliced to other lengths of conveyor belt to form a continuous conveyor belt.  The particular support structure has an elongate configuration so that when the belt is wound on the support structure, it extends along a winding path that has 180° curves at opposite ends, these being joined by upper and lower straight path sections parallel to the longitudinal axis of the support structure.  The use of this support structure, as well as the method of the present invention, provide greater efficiency and savings. Specifically, usually belt sections of greater lengths can be shipped, thus reducing costs of splicing the belt sections at the end location, as well as other advantages.

Filed: 1995-08-14
Granted: 2000-10-10
Abstract: A method and apparatus for reeling a traveling web (w), such as the paper web produced on a papermaking machine, comprises the concept of winding the on-coming traveling web onto a reel spool (16) which is horizontally supported rotatively, and which, in a preferred embodiment, moves translationally in a direction from the dry end of the papermaking machine towards the wet end of the papermaking machine as the diameter of the wound web roll (20) increases. The reel spool (16) is supported on a pair of spaced, substantially horizontally disposed rails. The on-coming web is first partially wrapped over a segment of a translationally movable support drum (44) with the upper side (wu) of the web facing inwardly toward the surface of the support drum (44). The support drum (44) is selectively nipped, or not nipped, with the web over the web roll (20) as it is commenced to be wound in a winding position, and continues to be wound into a web roll (20) on a reel spool (16). As the web roll (20) being wound increases in diameter, it is translationally moved upstream while being supported on the substantially horizontally disposed rails, and while torque is maintained on the reel spool (16).
