Title: A drive circuit for an actuator
IPC: G05D3/00
Filed: 1988-09-07
Abstract: A drive circuit for driving an actuator to cause 
intermittent movement to a given displacement comprises 
an oscillator circuit (101) for generating a clock 
signal, a divider circuit (102) for frequency dividing 
the clock signal and a timing circuit (103) for

Abstract: A laser balloon catheter intended primarily for 
coronary angioplasty includes a flexible tube (10) having 
an inflatable balloon (12) secured to its distal end, a 
central shaft (26) within the balloon (12) for carrying a 
guide wire (28), an optical fiber (32) for carrying laser 
radiation through the flexible tube (10) into the 
balloon (12), and a tip assembly (24) in the balloon (12) for 
directing laser radiation outwardly through a major 
portion of the balloon surface while limiting 
shadowing by the central shaft (26). The tip assembly (24) 
preferably includes a tip portion of the optical 
fiber (32) contained within a transparent, heat-formable 
tube (38) and formed into a spiral shape around the 
central shaft (26) by the heat-formable tube (38). The 
optical fiber tip portion (36) is tapered so that it 
directs laser radiation outwardly over its length. 
Deuterium oxide is preferably used for inflation of 
the balloon (12) because of its very low attenuation of 
laser radiation in the wavelength range of 
interest. The disclosed laser balloon catheter is 
capable of delivering 30-40 watts of laser radiation 
to a surrounding artery for times on the order of 30 
seconds without excessive heating of the balloon 
assembly.

system. A single linear accelerator is used to simultaneously accelerate a 
plurality of electron beams by using an electron beam deflection means such as 
a bending magnet to cause multiple beams to converge to a single stream of

Title: Apparatus for assembly and disassembly of packets of data communicated between a computer and a high capacity tape drive
IPC: G06F3/06
Filed: 1989-01-05
Abstract: A tape packet assembler/disassembler (TPAD) (7) for a 
tape drive (25) accumulates host-transmitted records, 
which may or may not be blocked by the host. The 
accumulated host-transmitted records are combined into 
packets (43) comprising a data portion (29) made up of 
data blocks (31,32) and of a trailer portion (30) made 
up of table entries (34 through 42) describing how to 
disassemble the packet. Host-transmitted commands to 
write a tape mark are intercepted by the TPAD (7) and 
replaced by corresponding information (47) in the 
trailer (30). Packets are accumulated in a buffer (13) 
in the TPAD, and are written to the tape drive (25) when 
the buffer becomes full, or upon a command from the host 
to reposition the tape, such as rewind. The interblock 
gaps that would ordinarily separate the host-transmitted 
records now separate packets, resulting in a 
considerable increase in the efficiency of tape 
utilization. The TPAD maintains in the trailer various 
pointers (37) to assist in forward and back spacing by 
file and records. It also can automatically and 
adaptively compress and decompress the user's data. To 
assist in this it also maintains in the trailer 
information (50) identifying data blocks containing a 
dictionary reset.

Title: Multiple fuel burner control system
IPC: F23N1/00
Filed: 1989-01-11
Abstract: A system for interconnecting a plurality of fuel burners (14-17) 
utilizes program modules (30-33) at each of the burners. The 
program modules contain microcomputers (86) and are interconnected 
with a communications module (41) by a first level data bus 
(40-43). This interconnection and the programming of the modules 
prevents cross talk between the units. The communications module 
further is connected to a second level data bus (70), that provides 
auxiliary functions without interaction with the data contained on 
the first data buses. The information supplied to the second data 
bus is limited so that no safety related function can be affected.

Filed: 1989-05-23
Abstract: Absorbent articles such as disposable diapers, incontinent pads, sanitary napkins and the like that have absorbent cores that are suitable for rapidly acquiring and containing liquid in an especially effective and efficient manner. The absorbent core comprises a storage layer comprising hydrophilic fibrous material and discrete particles of absorbent gelling material and having an acquisition aperture so it can quickly acquire this discharged liquid; and a liquid handling layer comprising a resilient material that is moisture insensitive so to rapidly acquire liquids into itself through the acquisition aperture and distribute the liquid throughout the liquid handling layer to the storage layer. The storage layer also allows the liquid handling layer to be "drained" of the liquid that is acquired so that the liquid handling layer may have sufficient capacity to acquire and distribute subsequent loading of liquids.

Title: Method of making metal matrix composite with the use of a barrier
IPC: C22C1/10
Filed: 1989-01-05
Abstract: A net shaped ceramic-reinforced aluminum matrix composite is formed by forming a permeable mass of ceramic material (10) with a defined surface boundary having a barrier, and contacting a molten aluminum-magnesium alloy (20) with the permeable mass of ceramic material (10) in the presence of a gas comprising from about 10 to 100 % nitrogen, by volume, balance nonoxidizing gas, e.g. hydrogen or argon.
