Title: Earth boring apparatus with control valve
IPC: E21B4/14
Filed: 1988-12-19
Abstract: An earth boring apparatus has a pneumatically operated earth boring tool, a flexible conduit or drill pipe connected to the tool and to a source of pneumatic fluid. The tool has an earth boring member and a reciprocally movable hammer positioned in the tool to apply a percussive force. A valve assembly in the flexible conduit or drill pipe substantially adjacent to the tool between the tool and the source of pneumatic fluid controls the flow of pneumatic fluid to the tool in response to the pressure of pneumatic fluid in the flexible conduit or drill pipe permitting the valve to be opened to permit flow of pneumatic fluid to the tool at a predetermined operating pressure to transmit an initial pulse of pneumatic fluid to initiate operation of the hammer. The valve is kept open at a lower pressure than that required to open it. One form of the valve is a pressure operated valve, spring-loaded toward closed position, opened at a first predetermined pneumatic pressure permitting flow to said tool and closed at a second, substantially lower, pneumatic pressure. Another form of the valve includes a valve, spring-loaded toward closed position, which opens in response to pneumatic conduit pressure, and spring loaded ball detents or a pneumatic pressure operated latch to secure the valve in an open position. The latch and valve are operated to closed position at a lower pressure.

Title: Conditioning perm wave composition and method
IPC: A45D7/04
Filed: 1989-05-27
Abstract: A single formula, mild, alkaline permanent 
wave conditioning composition provides a strong, long 
lasting curl like an alkaline permanent wave composi­
tion but leaves the hair soft like an acid permanent 
wave composition while minimizing further damage to 
already damaged hair. The composition contains a 
water-soluble alkali salt of thioglycolic acid, such 
as ammonium thioglycolate in an amount of about 2% to 
about 22% by weight; a water-soluble alkaline dithio­
diglycolate, such as diammonium dithiodiglycolate in 
an amount of about 0.1% to about 18% by weight; a 
hair softening and/or moisturizing agent, such as 
glycerine in an amount of about 0.1% to about 20% by 
weight; and sufficient additional alkali, if necessary, 
to bring the pH of the composition to about 7.5 to 
8.7. This composition is easy to use and apply without 
damaging the hair while providing a strong, tight 
curl and leaving the hair unexpectedly soft. The 
composition can be lotion or water wrapped and can be 
used with or without heat. Unexpectedly, the composi­
tion is applied to any type of hair, regardless of 
structural damage to the hair, resulting in the same 
degree of curl tightness and softness.

Title: Thermo-magnetic recording method
IPC: G11B11/105
Filed: 1989-07-12
Abstract: The present invention adopts as the basic 
s.tructure of its thermomagnetic recording medium an 
arrangement consisting of a first (11) and a second magnetic 
thin film (12) having perpendicular anisotropy and a third 
magnetic thin film (13) having in-plane magnetic anisotropy 
or small perpendicular magnetic anisotropy interposed 
therebetween, formed into a laminated structure by being 
magnetically coupled to the adjoining films in turn, 
modulates and switches, in accordance with information 
to be recorded, a first heating condition and a second 
heating condition, with the medium applied with a 
predetermined external magnetic field H ex  in the 
direction perpendicular to the plane of the film, the 
first condition being that for raising temperature of 
the medium to a first temperature T₁ which is virtually 
above the Curie temperature T C1  of the first magnetic 
thin film and not causing reversal of the magnetic 
moment in the second magnetic thin film and the second 
condition being that for raising temperature of the same 
to a second temperature T₂ which is virtually above the 
Curie temperature T C1  and sufficient to cause reversal 
of the magnetic moment in the second magnetic thin film, 
 
 
to thereby form an information bit (magnetic domains) in 
the first magnetic thin film, and adapts during the 
course the medium is cooled from the heated states such 
that two states established by the different 
relationships between the directions of magnetization of 
the first and second magnetic thin films are finally 
formed whereby the recording of the information is 
performed, and thus the present invention brings about 
conditions enabling alteration of recorded information 
to other information, that is, enabling so-called 
overwriting. Especially, by virtue of the third 
magnetic thin film, the present invention achieves 
simplification of the apparatus for applying the 
magnetic field.

Abstract: Mit dieser mechanischen Einrichtung werden Rundringe problemlos 
erfasst und um den in der Lage immer gleichen Mittelpunkt gedreht. 
Durch die Verformung, mittels zweier gegenläufiger Formbacken, 
aus der Kreisform, entstehen am Ring je nach Drehposition 
Zugspannen an der Oberfläche des Rundringes. Kleinste 
Oberflächenfehler in Form von z.B. Rissen werden dadurch sichtbar. Die 
Bildfenster der CCD-Kamera nehmen jeweils einen bestimmten Umfang 
des Ringquerschnitts auf, in dem Bereich, wo die Oberflächenspannung 
erhöht ist. Durch die mechanisch sichere Verformung bei immer gleicher 
Lage und Form des Rundringes ist erst eine Automation des 
Prüfvorgangs mittels digitaler Bildverarbeitung möglich, welche den 
Einsatz von Rundringen für Sicherheitssysteme (z.B. im Auto) 
erfordert.

Patent EP-0374807-A3 (EP)
IPC: C08J3/12
Filed: 1989-12-18
Abstract: A process and apparatus are disclosed for producing 
polymerized beads containing actives such as perfumes and 
pesticides, by forming droplets from a solution of monomers 
and the actives. The solution is subjected to ultraviolet 
light to initiate polymerization. The droplets are caused to 
fall through a reaction vessel as polymerization continues so 
as to polymerize substantially spherical beads containing the 
actives. In one embodiment, the droplets are irradiated as 
they fall through the reaction vessel. In a second 
embodiment, the solution is irradiated prior to droplet 
formation and the fall. The beads are collected and can be 
cured if necessary. The process is preferably performed in 
an inert gas environment which most preferably is nitrogen. 
A nitrogen stream can serve as a carrier for the monomers and 
active ingredients. The nitrogen environment is maintained 
in the reaction vessel and in the curing structure, if 
present.

Title: Method and apparatus for logic simulation
IPC: G06F17/50
Filed: 1989-03-06
Abstract: Determination of an operation of a logic circuit 
is usually called logic simulation. The logic simulation 
in which changes in signal status at input terminals and 
output terminals of an element in the logic circuit to 
be simulated are represented by events and the signal 
status at the output terminal is calculated only for the 
element in which the event has occurred at the input 
terminal thereof, is called an event driven logic simula­
tion. In the event driven logic simulation, a current 
time is used to decide and extract the event to be 
processed. In the prior art apparatus, the decision and 
extraction are interrupted when the current time is updated. 
In the present invention, identifiers (colors) are 
imparted to the events to group the events. The current 
time is updated when the event having a special color is 
not present. Thus, a simulation speed in the event 
driven logic simulation method and apparatus is improved.

Title: Wide range linear automatic gain control amplifier
IPC: H03G3/30
Filed: 1989-03-06
Abstract: An automatic gain control (AGC) amplifier (10), which may be 
fabricated as a monolithic integrated circuit, provides linear gain 
response in dB over a wide dynamic range. The AGC amplifier (10) 
comprises multiple cascode amplifier stages (A,B,C,D) connected in 
cascade to provide high power handling capability and high gain. A 
control voltage (VAGC) is input to a linearization circuit (16) 
which provides an output to an operational amplifier (18) that 
functions as a voltage controlled voltage source (VCVS). The VCVS 
(18) produces a conditioned control voltage (VAGC′) which is fed 
back to the linearization circuit (16) and provided to each of the 
cascode amplifier states (A,B,C,D). The conditioned control voltage 
(VAGC′) provided to each amplifier stage (A,B,C,D) causes current to 
be removed from the cascode amplifier, thereby lowering its gain. 
The overall gain of the AGC amplifier (10) in dB varies linearly 
with the control voltage (VAGC) applied to the linearization circuit 
(16).
