Abstract: A process is provided for producing high-active detergent agglomerates through multi-stage surfactant paste injection. According to the process, starting detergent materials are mixed with an initial amount of surfactant paste and then allowed to age for a specified period of time. Following the initial paste injection and aging period, additional amounts of surfactant paste are injected incrementally to make a final detergent agglomerate having at least about 45% by weight of surfactant.

Abstract: A communications device and method for effectively managing bandwidth within a telecommunications network carrying both time division multiplexed signals as well as data signals. The communications device having dialable TDM/cell and/or packet-based bandwidth management capability so that a network operator can select to manage bandwidth for any particular signal on in STS, VT, or cell or packet basis.

Abstract: A clothing protective device which is particularly adapted to be worn by a man, woman or child, and which in particular will assist in the protection of clothing while dining or engaging in other activities which may stain clothes. In essence, the device is essentially in the form of a so-called napkin holder which can be readily transported in a clothing pocket or a purse.

Abstract: A process for preparing low density detergent agglomerates is provided. The process involves the step of: (a) agglomerating a detergent surfactant paste or precursor thereof and dry starting detergent material having a median particle size in a range from about 5 microns to about 70 microns in a first high speed mixer to obtain detergent agglomerates having a median particle size of from about 100 microns to about 250 microns; (b) mixing the detergent agglomerates with a binder in a second high speed mixer to obtain built-up agglomerates having a median particle size in a range of from 140 microns to about 350 microns; and (c) feeding the built-up agglomerates into a fluid bed dryer in which the built-up agglomerates are agglomerated with another binder and dried to form detergent agglomerates having a median particle size in a range from about 300 microns to about 700 microns and a density in a range from about 300 g/l to about 550 g/l.

In essence, the device is essentially in the form of a so-called napkin holder which can be readily transported in a clothing pocket or a purse and which is imparted a large number of uses in addition to being merely a clothing protective device.

Abstract: A device and method for monitoring a foetus over a period of time. The device includes an electrocardiograph for receiving and processing signals generated by the foetal heart and received from an electrode attached to the abdomen of the mother. The device also includes a second signal receiving and processing means for signals generated by a pressure or acceleration detector that is also attached to the abdomen of the pregnant mammalian animal. The pressure detector produces signals representative of the sounds of foetal heartbeat. The device also includes a comparator means to compare the respective sets of signals, and output means to produce an output indicative of the comparison between the two sets of signals.

Abstract: A mask and harness assembly (10). The assembly (10) includes a mask (12) a harness (14) including at least one strap (16) connected to the mask (12) and at least one fluid delivery tube (18) connected to, and in fluid communication with, the mask (12). The strap(s) (16) and the tube(s) (18) being adapted to locate the mask (12) at a predetermined location on the head of the wearer.

Abstract: A device and method for detecting and recording the snoring of a patient. The device comprises a piezoelectric sensor, placed below a sleeping patient on a mattress, which generates signals representative of the sub-audible vibrations of the patient's airway which are present during a snore. The signals generated by the sensor can be amplified by an amplifier and processed by a signal processing circuit. The sensor can also generate signals representative of the patient's breathing cycle and general movement of the patient. The signal processing circuit can be adapted to discriminate the signals generated by the sensor and then output these signals for analysis. The output can be used to determine the presence of snoring by the patient and the snoring pattern can also be used to detect episodes of obstructive sleep apnea.

Abstract: Choline base is prepared by the electrolysis of choline chloride in electrolytic cells having the anode and cathode separated by a cation exchange membrane. Color stabilization of choline base is effected through concentration control and/or the addition of a sulfite prior to electrolytic manufacture of the choline base.

Abstract: A process for bleaching wood pulp with sodium hydrosulfite in the presence of at least 2 weight percent of hexamethylenetetramine based upon the weight of sodium hydrosulfite.

Abstract: An aqueous composition for bleaching wood pulp containing sodium hydrosulfite, and at least 2 weight percent hexamethylenetetramine based upon the weight of sodium hydrosulfite, wherein the solution has a pH between about 4 and about 11. The hexamethylenetetramine prevents hydrogen sulfide formation during bleaching of the wood pulp.
