Title: Motor driven garden waste shredder
IPC: B02C18/18
Filed: 1988-05-20
Abstract: A garden chopping/shredding apparatus has a frame provided with an upwardly open intake hopper on the frame having a lower end in which is in turn provided a generally horizontal blade plate and formed about the axis with a plurality of angularly spaced apertures. Respective flat blades carried on the blade plate have cutting edges above the apertures and a plurality of prechopping blades carried on the blade plate projecting upward therefrom have cutting edges inclined upward and inward toward the axis. The drive rotates the plate and the blades in a predetermined direction about the axis so as to define with the cutting edges of the flat blades a generally planar and circular orbit perpendicular to the axis and having an inner periphery offset radially outward from the axis and to define with the cutting edges of the chopping blades an upwardly tapered frustoconical orbit centered on the axis and having a small-diameter upper end and a large-diameter lower end. A deflector or abutment plate fixed against rotation in the lower end of the hopper has a panel with a lower cutting edge juxtaposed with the orbit of the flat blades and an inner edge juxtaposed with the orbit of the prechopping blades. This panel forms an acute angle open backward into the direction of rotation with the orbit of the flat blades and its lower cutting edge extends generally tangentially to a circle centered on the axis and having a greater diameter than the inner periphery of the orbit of the flat blades.

Abstract: A centrifuge for separating constituents of fluids, 
diluting the constituents and inoculating a reagent 
includes a spinning assembly for spinning a processor 
member. The processor member includes fluid and diluent 
compartments (12,14), separation chambers (18, 22) for a fluid and for a 
diluent, a mixing chamber (34), and a reagent chamber (38). The 
fluid compartment is in communication with the fluid 
separation chamber by a first passage. The diluent 
compartment and diluent separation chamber are 
communicated by a second passage. The first and second 
passages are oriented such that centrifugal force moves 
the fluid and diluent through the first and second 
passages into the respective chambers. The chambers are 
aligned to prevent outflow under the influence of 
centrifugal force but to allow outflow into measuring 
passages upon braking the spinning of the processor 
member. Spinning the processor member after braking 
generates a centrifugal force moving the fluid and 
diluent through the measuring passages into a mixing 
chamber. Braking the spinning of the processor member 
again applies a braking force on the mixed fluid and 
diluent moving this mixture into the reagent chamber.

Abstract: Method and device for treating angina 
pectoris and preventing tolerance to nitrate drugs 
which takes into account the frequent need to provide 
the patient with relief from or prevention of 
pre-waking or early morning angina. The treatment 
comprises administering a daily unit dose of the 
nitrate before bedtime in a dosage form that (1) 
provides a washout period of 3 to 12 hours by 
sufficiently retarding delivery of the nitrate to the 
patient during the washout period that the rate of 
delivery is so low as to be insufficient to cause 
tolerance to said nitrate in said patient; (2) at the 
end of the washout period and at least 30 minutes 
before the patient expects to awaken, initiates an 
effective delivery period during which the dosage 
form provides an initial effective delivery rate 
sufficient to provide an antianginally effective 
concentration of nitrate in the blood stream of the 
patient; and (3) thereafter, during a ramp-up 
delivery period, delivers the nitrate at an 
increasing rate until a final delivery rate is 
achieved, which is from 125% to 1,000% of the initial 
effective delivery rate. At the end of the ramp-up 
period, delivery is exhausted or otherwise 
terminated. A new unit dose is administered at 
bedtime, and the cycle is repeated.

Title: Professional office system printer support for personal computers
IPC: B41J2/485
Filed: 1988-09-27
Abstract: A printer support utility provides full support for all 
compatible printers attached to personal computers operating in 
a professional office system environment. The utility provides 
an interface that interprets ANSI printable data and 
restructures the data to allow for improved printing of 
underscore, overstrike and highlight, especially in non-impact 
printers such as laser printers and ink jet printers. The 
utility reads each line of printable data from an input file 
and tests the line for a line control indicating a new print 
line. If not a new print line, the utility scans the line for 
underscoring, overstriking and highlighting of characters; but 
if a new print line, the utility converts the scanned line to a 
personal computer printer line and writes the line to an output 
file. Finally, the converted print line in the output file is 
printed.

Abstract: Two intermediate frequency signals, which are used 
in a polarization diversity optical heterodyne receiver 
operable according to demodulation and subsequent 
combination and have a common intermediate signal 
frequency variable in an intermediate frequency range, 
are subjected to delaying (21) relative to each other and 
then combined (23) into a combined intermediate frequency 
signal. A frequency discriminator (24) discriminates 
the intermediate signal frequency of the combined 
intermediate frequency signal to produce a control 
signal for use in stabilizing a local optical frequency (14) 
of a local beam used in combination with a signal beam (11) 
susceptible to polarization fluctuation. A delay may 
be given for the delaying to one of the two intermediate 
frequency signals alone. Alternatively, a delay may 
be given for the delaying to only one of two local 
beam components which are coupled to two signal beam 
components for use in producing the two intermediate 
frequency signals.

Title: Polyvinyl chloride blends having improved physical properties
IPC: C08L27/06
Filed: 1989-09-06
Abstract: Polyvinyl chloride-acrylate copolymers are 
plasticized with plasticizers to produce a 
composition having low hardness values. For example, 
Shore A values of 55 or less can be readily 
achieved. Such low values are often achieved by 
utilizing low amounts, for example less than 100 
parts by weight, of the plasticizer for every 100 
parts by weight of the PVC-acrylate copolymer. Low 
Shore A hardness values are also aided by the use of 
high amounts of acrylate units in the copolymer, that 
is amounts of at least 45 percent by weight based 
upon the total weight of the copolymer. The 
copolymer is made from a vinyl constituent which is a 
vinyl chloride monomer with an optional vinyl 
component comonomer and one or more acrylate monomers.
