Abstract: A bidirectional communication link and a method of contemporaneously transmitting signals having an optical carrier of a common wavelength along an optical fiber are disclosed. The link comprises an optical fiber (160) having a first and a second end. A transmitter (260) is provided for launching a first optical carrier of a first wavelength onto the fiber (160) at the first end thereof, the transmitter (160) including a modulator (300) for modulating the first carrier with a first modulating signal (D) confined to a first frequency spectrum upon the first carrier. Further, a second transmitter (270) is provided for launching a second optical carrier of the same wavelength along the fiber (160) at the second end thereof. The second transmitter (270) includes a modulator (360) for modulating upon the second carrier a second modulating signal (U) confined to a second frequency spectrum not overlapping the first spectrum. A first receiver (440) is coupled to the second end of the fiber (160) for extracting the first modulating signal (D) from the first optical carrier, and a second receiver (420) is coupled to the first end of the fiber (160) for extracting the second modulating signal (U) from the second optical carrier.

Abstract: The invention relates to a process and apparatus for cleaning a swimming pool, where the apparatus or device, moves back and forth in the swimming pool, and where the device has driving gears or belts that can be switched to drive reverse or forward during operation. A contact rail is frontally positioned in the cleaning casing of the device, and a swich rail is positioned at the rear of the casing. Correction-dependent signals are obtained by the device striking an obstacle and these signals are supplied to a gear via a control mechanism. Upon obtaining such signals, the driving gear or belt slows down and remains still for so long until the other driving gear or belt which is still moving turns the cleaning device around and until the rear switch rail is activated. The signals resulting from the switch rail are used for switching the gear to reverse and for straightening out the cleaning device to a new position and prepare it to a forwards motion to continue its course along the swimming pool.

Abstract: A printed circuit board comprising rigid and flexible parts contains not only the rigid layer or layers, but a layer of temperature-resistant woven fabric or paper which is coated and impregnated with flexible cured synthetic resin and which is both a composite film and the substrate for the conductor patterns in the flexible part of the printed circuit board. The essence of the process for manufacturing the printed circuit board is that, in each of the parts which are to be of flexible construction, a filler piece (3) is punched out of the rigid layer or layers (1) before laminating the single layer composite, the filler piece (3) being identical to said part in its dimensions, and is then immediately reinserted as an exact fit in the punching window by the reverse procedure and then a nonwoven fabric coated and impregnated with synthetic resin or the paper prepared in this way is placed as a prepreg (5) directly and over the entire surface of the rigid single layer (1) on the circuit side. In this process, the adhesion of the prepreg (5) is prevented in the future flexible regions by a previously applied release layer (4) on the rigid layer. This is followed by coating the prepreg (5) with the ductile copper foil (22), the forming of the conductor patterns (24) and the removal of the filler piece (3) in the flexible part of the rigid single layer (1). <IMAGE>

Abstract: A method for memory management within a document history log in a data processing system having multiple resource objects which are accessible by a plurality of users within the data processing system. A history log is created (64) and associated with each resource object for which documentation of selected activities is desired. Next, a maximum memory size for each document history log is specified (66) along with a protocol which dictates the order in which that memory shall be allocated (68) after the maximum memory size has been exceeded. Thereafter, documentation of each activity which relates to a selected resource object is stored (80) within its associated document history log after determining whether or not sufficient memory space is available (78). In the event sufficient memory space does not exist within the document history log, new activities are overwritten (82, 84, 86) in accordance with the specified protocol. In the event such overwriting has not been specified, an appropriate error message is generated. In this manner it is possible to ensure that activities relating to a particular resource object are recorded within a document history log after exceeding the maximum memory space of that document history log.

Abstract: An end wall for beverage containers, in which the end wall has a center section (15) extending across its width, and reduced thickness side sections (13,14) on opposite sides of the center section, thereby enabling the end wall to be manufactured with less material than is required in conventional end wall constructions. The center section is of the same thickness as used in conventional container end walls, and is able to support a pull tab (16) and associated pull ring (17), while at the same time reinforcing the end wall. The reduced thickness side sections (13,14) are only about one-half as thick as the center section (15), and all shaping to produce the reduced thickness is performed on the top surface of the end wall, so that the underside remains flat.

   continuously calculating said relative distance between the compressor operating point and the surge limit as a function of one or more measured process variables and adjusting the position of said anti-surge valve by a closed loop response of the control system to prevent said relative distance between the compressor operating point and the surge limit from decreasing below a minimum margin of safety, said minimum margin of safety including both constant and variable parts, and adding an open-loop response to the output of said anti-surge control system whenever the relative distance between the compressor operating point and the surge limit is below a preset level of danger because when said relative distance between the compressor operating point and the surge limit is located below said preset level of danger, the operating point may cross the surge limit line; and 
   maintaining said open-loop response at zero under steadystate conditions, increasing said open-loop response by an amount proportional to the instantaneous rate at which said controlled variable is approaching said surge limit whenever the relative distance between the compressor operating point and the surge limit decreases below the preset level of danger, and at preset time intervals thereafter so long as said relative distance between the compressor operating point and the surge limit continues to be below said preset level of danger, and decreasing said open-loop response slowly toward zero whenever said relative distance between the operating point and the surge limit becomes higher than the preset level of danger.
