Title: Soft absorbent tissue paper with high permanent wet strength.
Inventor: PHAN DEAN VAN
IPC: D21H17/37
Filed: 1992-10-19
Abstract: Tissue paper webs useful in the manufacture of soft, absorbent products such as paper towels, napkins, and facial tissues, and processes for making the webs. The tissue paper webs comprise papermaking fibers, a biodegradable quaternary ammonium compound, a polyhydroxy plasticizer, and a permanent wet strength resin. The process comprises a first step of forming an aqueous papermaking furnish from the above-mentioned components. The second and third steps in the basic process are the deposition of the papermaking furnish onto a foraminous surface such as a Fourdrinier wire and removal of the water from the deposited furnish. An alternate process involves the use of the furnish containing the aforementioned components in a papermaking process which will produce a pattern densified fibrous web having a relatively high bulk field of relatively low fiber density in a patterned array of spaced zones of relatively high fiber density.

Title: Self-optimizing detergent controller
Inventor: BRADY DANIEL F
IPC: D06F33/37
Filed: 1992-10-26
Abstract: An apparatus and method for programming a detergent controller to vary the detergent concentration set-point according to the time of day and to achieve detergent concentration levels quickly without incurring overshoot. Thus, the present invention insures that the warewashing machine is operated at optimum efficiency and cost. To vary the set-point according to the time of day, the invention combines the features of a microprocessor, a clock and a controller into one unit. The user enters the time setting and set point into the controller. The microprocessor then compares the real-time clock signal with the user time settings and outputs an appropriate set-point value from the microprocessor to the controller. To achieve detergent concentration levels quickly without incurring overshoot, the controller senses the detergent concentration and dispenses the proper detergent level to the warewashing machine according to a predetermined detergent feed time based on the previous response time and the programmed set-point. Thus, the controller can change the response function if and when conditions change.

Abstract: A controlled-output power amplifier (50) is provided having a wide dynamic range in a plurality of output power levels. The controlled-output amplifier (50) includes an amplifier (12) for receiving an input signal (14) and for providing an output signal (16) therefrom. A power detector (24) is employed for rectifying a sample signal and providing a DC output signal (26) therefrom. An active variable coupling network (52) which preferably includes a varactor (62) is connected between the output of the amplifier (12) and the power detector (24). The variable coupling network (52) receives the amplifier output signal (16) and further receives an isolation voltage (54) and adjusts the amount of isolation between the amplifier (12) and the power detector (24). For high output signals, the isolation voltage (54) causes a high isolation thereby causing less power to be transferred to the power detector (24). The isolation voltage (54), similarly, decreases the isolation for low output signals such that more power is transferred to the power detector (24). The DC output signal (26) is then compared with a fixed voltage reference (30). The voltage comparison provides an error voltage (34) which is used to adjust the gain of amplifier (12) so that the output signal (16) of the amplifier (12) is set to a desired magnitude.

At each frame, image data S2 is sequentially stored in the image data multilayer memory 8 which consists of frame memories formed in a ring shape. When an anomalous phenomena (image) which includes this image data S2 is detected by the anomalous phenomena detecting device 2, then for image data S2 and anomalous image data S4, from a time immediately before the occurrence of an anomalous phenomena until the elapse of a prespecified period of time, maintenance and storage in the multilayer memory 8 for image data and in the multilayer memory 7 for extracted anomalous image data by the start/stop control circuit 6. Following this, the image data S2 and the anomalous image data S4 from immediately before the occurrence of an anomalous phenomena until the elapse of a prespecified period of time is forwarded to storage device 10 by the data transfer circuit 9. Based on the thus obtained images from before and after the occurrence of an anomalous phenomena, analysis and resolution of an anomalous phenomena occurring within a surveilled area may be carried out.

Abstract: Sur une ligne à plusieurs canaux logiques, on surveille la transmission de paquets de données. Il existe pour chaque canal logique (i) une valeur de comptage (Li) et lorsqu'arrive un paquet de données ou lors de chaque créneau temporel si cette ligne est prévue pour une transmission à multiplexage temporel, pour chaque créneau où un paquet de données aurait pu arriver, seule cette valeur de comptage (Lm) concernant un seul canal (m) est décrémentée. On détermine alors si le paquet de données éventuellement reçu doit être réexpédié ou ignoré, par comparaison entre une valeur calculée (Fn) et une valeur de seuil (Tn) relative au canal (n) dont relève ce paquet. Pour le calcul de cette valeur de discrimination (Fn), on utilise le nombre de canaux qui n'ont pas été décrementés après décrementation du canal (n) dont relève ce paquet reçu. On peut ainsi faire ressembler la valeur calculée (Fn) à la valeur calculée, ou valeur de niveau, telle qu'utilisée avec les procédés antérieurs pour traiter des pertes de paquets survenant dans un réseau. Pour chaque paquet reçu, ce procédé n'exige que de décrémenter une valeur de comptage (Ln), ce qui implique un gain de temps significatif et une simplification des circuits utilisés pour appliquer ledit procédé.
