Title: Aromatic compounds having sulfonyl groups and processes for the production of the same
Inventor: TAGUCHI YOSHIO
IPC: C07C317/44
Filed: 1986-12-16
Granted: 1991-04-02
Abstract: An aromatic compound having sulfonyl groups, as an intermediate or raw material of polyimides having a good and well-balanced heat resistance and moldability is effectively produced by reacting a compound represented by the general formula, R - Ar - R   wherein Ar is     ,     ,            or     , Y is a bond, oxygen atom, sulfur atom, SO2, CH2 or     and R is a hydrogen atom or -SO2X and X   is a halogen atom or alkali metal, with a compound represented by the following general formula,   wherein X1 and X are simultaneously methyl groups or form      or      and Z is a hydrogen atom, alkyl group having 1 to 6 carbon atoms or aryl group having 6 to 8 carbon atoms and R1 is a hydrogen atom, -SO2X, halogen atom or nitro group, X is a halogen atom or alkali metal and R and R1 are not same simultaneously, either of which contains -SO2X group as a necessary group.

Title: Fluorescent tube dunnage
Inventor: CREADEN DAVID E
IPC: B65D71/00
Filed: 1987-01-06
Granted: 1991-10-22
Abstract: FLUORESCENT TUBE DUNNAGE            Abstract of the Disclosure Molded  synthetic  resin  dunnage  supports for packing of elongated fragile fluorescent tubes are provided which are designed for automated dis-pensing during packaging and give protection against tube breakage at least equivalent to that of conven-tional molded pulp supports.   In preferred forms, the dunnage support is formed from polyvinyl chlor-ide sheet material (0.014 inch thickness) and in-cludes  plural  juxtaposed  tube-receiving  sockets together with a rear side lip and front side ledge platforms; the lip carries laterally spaced upright nibs which, in conjunction with the ledge platforms, prevent complete nesting of the supports, so that an interfitted  support  stack  presents substantially even access spaces between individual supports for easy machine dispensing.  The tube-receiving sockets are provided with alternating, vertically spaced, upwardly and downwardly opening arcuate,  striated tube-engaging sections so that a single support can simultaneously engage and cushion a pair of tube layers in a shipping carton.  The dunnage design affords a high degree of protection for the packaged tubes and can safely absorb potentially destructive impacts without tube breakage.

Title: Liquid applicator device
Inventor: KNICKERBOCKER MICHAEL G
IPC: B43K5/08
Filed: 1987-04-13
Granted: 1992-10-27
Abstract: LIQUID APPLICATOR DEVICE ABSTRACT OF THE DISCLOSURE       A liquid applicator device and the method of making the applicator device is disclosed for applying a liquid such as a paint, a perfume, a chemical, a coating or the like to a surface by writing, marking or painting. The liquid applicator device includes a container for the liquid and an applicator dispensing mechanism. The applicator dispensing mechanism includes an inner subassembly having a valve and an outer subassembly having the surface applicator. The valve regulates the flow of the liquid from the container to the surface applicator. The valve of the applicator device may be opened to allow the liquid to flow from the container to the surface applicator upon depres-sion of the surface applicator or upon depression of a valve actu-ator. The liquid applicator device incorporates an improved sealing member for sealing with the sides of the surface applicator for reducing the flow of the applicator liquid along the side of the surface applicator. The surface applicator may be in the form of a fiber tip, a brush or similar applicator. The applicator dispensing mechanism may be fabricated independent of the attachment to the container.

Abstract: ABSTRACT                       THROTTLE CONTROLS            A combined hand and foot control for a prime mover throttle member 10 including a hand control 12, a foot control 13, and a combining device 14 for combining the hand and foot controls.  The combining device includes a plastics support housing 14a,14b and a combining member 34 slidable within the housing in first and second opposite directions.  A first cable linkage means connects the combining member 34 with the throttle member 10 so that movement of the combining member in the first direction moves the throttle member towards a fully open position, bias means 38 acting to bias the throttle member towards an idle position and hence bias said combining member 34 in the second direction via the first linkage 17.  A second cable linkage 16 connects the foot control 13 and combining member 34 for movement of the combining member in the first direction, and a third cable linkage 15 connects the hand control 12 with the combining member 34 via a connection 15c,35a capable of moving the combining member in the first direction only and allowing sliding of the combining member in the first and second directions relative to the third linkage 15.  The arrangement is such that any throttle member position set by the hand control 12 can be increased using the foot control 13 by the second linkage 16 sliding the combining member 34 in the first direction relative to the third linkage 15.

Title: Hybrid watermattress with concave softsides
Inventor: GOODALE CLARKE W
IPC: A47C27/08
Filed: 1987-08-05
Granted: 1991-01-08
Abstract: ABSTRACT     A watermattress comprising a bladder formed of water impervious sheet material and having a major top panel, a major bottom panel, and a side panel.  The bladder can be filled with water.  The side panel has an initial shape when the bladder has no water within it and a first particular shape when the bladder is filled with water.  A sidewall extends laterally of the bladder for supporting the bladder.  The sidewall has a top surface, a bottom surface, and a side surface facing the side panel of the bladder. The side surface of the sidewall has a second particular shape when the sidewall is in a generally uncompressed state.  The first particular shape is generally complementary to the second particular shape.  A mattress cover surrounds the bladder and the sidewall.
