Abstract: Infusion packets have envelopes of heat-sealable material with a looped thread within the packets to wring moisture from the packet in use. A central part of the thread loop is held in a widened region of one edge seal while the ends of the loop project through the opposite edge seal in which they are movable when the loop is to be contracted. The packets are produced by forming a continuous series of thread loops on one elongate web and placing doses of infusion material on a second elongate web before bringing the webs together with the thread loops and infusion material between them. The two webs are then welded together and the individual packets are separated from the joined webs.

Abstract: A dispensing closure for a container is provided having a cap, a receiving cavity on an outer wall of the cap and a spout rotatably lodged within the cavity. Product from the container can exit through the cap and be dispensed through a channel in the spout when the latter is rotated to a dispensing position. The spout is formed with a pair of flanking wings each having a trunnion/bearing mechanism on an outer surface.

Abstract: A process is provided for preparing a silicone elastomer composition for cosmetic products which includes the steps of feeding the silicone elastomer composition comprising a silicone rubber in a carrier fluid into a reactor, mixing the composition in the reactor, delivering the composition from the reactor into a high pressure pump, pumping the fluid into a device for reducing particles of rubber into smaller sizes and recirculating the resultant size reduced particles back to the reactor. The device for reducing particle size is preferably a high pressure fed homogenizer, most advantageously a sonolator.

Abstract: Recombinant mycobacterial vaccine vehicles capable of expressing DNA of interest which encodes at least one protein antigen for at least one pathogen against which an immune response is desired and which can be incorporated into the mycobacteria or stably integrated into the mycobacterial genome. The vaccine vehicles are useful for administration to mammalian hosts for purposes of immunization. A recombinant vector which replicates in E. coli but not in mycobacteria is also disclosed. The recombinant vector includes 1) a mycobacterial gene or portions thereof, necessary for recombination with homologous sequences in the genome of mycobacteria transformed with the recombinant plasmid; 2) all or a portion of a gene which encodes a polypeptide or protein whose expression is desired in mycobacteria transformed with the recombinant plasmid; 3) DNA sequences necessary for replication and selection in E. coli; and 4) DNA sequences necessary for selection in mycobacteria (e.g., drug resistance).

Abstract: In order to provide a particulate zero-phosphate laundry detergent composition with reduced tendency to agglomeration, the composition comprises:i) from 30 to 80 wt % of a granular base powder comprising:a) from 5 to 60 wt % (based on the composition) of organic surfactant, andb) from 10 to 80 wt % (based on the composition) of alkali metal aluminosilicate detergency builder,ii) from 1 to 5 wt % of sodium silicate not within the granular base powder,wherein the sodium silicate (ii) is all present in the form of separate cogranules consisting essentially of sodium silicate and sodium carbonate in a ratio within the range of from 3:1 to 1:3, and where the tendency of the composition to form granules having a particle size of 2000 .mu.m or larger on storage is less than if the sodium silicate (ii) were present in the form of separate granules of sodium disilicate.

Abstract: In order to enhance the stability of sodium percarbonate bleach in particulate detergent compositions, crystalline aluminosilicate and a water-soluble alkali metal silicate in an amount of from 1-20% by weight based on the aluminosilicate are included in the non-spray dried base powder. In order to obtain the stabilizing effect, the crystalline aluminosilicate comprises zeolite MAP or the alkali metal silicate is homogeneously dispersed with respect to the aluminosilicate.

Abstract: A cosmetic composition is provided which includes ascorbic acid (Vitamin C) solubilized by a crosslinked non-emulsifying siloxane elastomer in a carrier medium of a volatile siloxane. Aesthetic properties are also improved by the presence of the crosslinked non-emulsifying siloxane elastomer.

Abstract: The present invention is a DC to AC switching converter that does not require a dead zone. The output node of the classical switching pair is separated into two output nodes which eliminates the current path that made the dead zone necessary. Each of the switches are connected between +Edc and -Edc in a complimentary fashion. By eliminating the direct connection between the two switches, both switches can be operating simultaneously without any danger of failure. Both switch outputs pass through a current sensing feedback device and an output coil. The outputs of each coil are connected to the output of the switching converter having a filter capacitor connected to ground. This arrangement provides switching bias current during the zero current crossover point thereby eliminating the ringing and oscillation distortion that occurs in the dead zone. The desired output voltage waveform is a result of the summation of the two switch outputs after the high speed component has been removed through filtering.

Abstract: An improved cutting head for a water jet cutting assembly utilizing water or other liquid medium at ultra high pressure, with the cutting head including an assembly with an elongated body having a central bore along its axis and including a delivery nozzle at the distal end of the assembly. Alignment of the components is maintained by incorporating a process of manufacture which utilizes the formation of a single bore extending through the body so as to both form and maintain axial alignment of the components. The arrangement is further characterized by having mating surfaces which are free of gaskets or other packing material, thereby establishing, maintaining, and preserving proper axial alignment of components.
