Abstract: ABSTRACT:      An improved beverage infusion device and a method of rapid brewing an infusible beverage substance such as fresh fine ground, roasted coffee by air agitation in an air-water chamber. The wall of the chamber is constructed of a fine porous filtering material that confines particles of coffee during agitation thereof with water of an amount necessary for brewing either one or more serving portions of coffee. An air conduit directs air underneath the coffee particles accumulated in the air-water chamber that is immersed in hot water. The hot water enters the porous wall of the air-water chamber saturating the coffee particles. One or more intermittent burst of air are directed by the conduit under the coffee particles thereby momentarily suspending the coffee particles in the water and agitating the coffee particles and the water. The water solubles of the coffee are extracted rapidly and mixed with the water to create a beverage.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a multi-purpose, one-piece implement or tool which is used to facilitate the putting on and removal of shoes and boots.      The shoe horn is the tool commonly in use to assist in putting on shoes, while the boot caddy, a separate device, is used to aid in removing boots.  The boot caddy requires the wearer to put one foot on a board to hold the caddy down, and to put the other foot into a fork-like device in order to pull the foot out of the boot.  For this procedure to work, both feet are placed close together, one on the slanted board of the caddy and the other in front, and the arms are used to steady the body.  This method can create uncomfortable balance problems which are especially dangerous for older people.

Abstract: A B S T R A C T     A PROCESS FOR GENERATING MECHANICAL POWER      Process for generating mechanical power by premixing a gaseous fuel with steam, burning the fuel/steam mixture and expanding the hot combustion gas in a turbine. Preferably the expanded gas is cooled to a temperature in the range of from 150°C to 250°C, and then used for heating water by indirect heat exchange to a temperature in the range of from 130°C to 200°C. The hot water may be evaporated into the gaseous fuel by contacting it therewith countercurrently. Steam is thus generated at a relatively low temperature by evaporating preheated water into the fuel gas stream to be burned in the combustion chamber of a gas turbine. In this way waste heat of a low temperature level can be put to good use.

The latter meshes with a  plurality  of bevel   sprockets,  which  are  located  along a circumferential line and having perpendicular axes intersect-ing the axis of   said bevel gear wheel.   Each sprocket is mounted  at one  end  of  a  round cross-section bar the other end  thereof  is  provided  with  a  threaded  portion  engaging with a nut screw formed in a block which supports cantilever-wise  a  rod.    In  operation,  by  rotating  the  horizontally extending  shaft,  the  individual  blocks  jointly  move  along the threaded portion of  their respective round cross-section bar  thereby causing the related rods to move away from and towards one another.

Abstract: Abstract A solid lubricant such as MoS2 is applied to medium to high carbon and stainless steels after surface voids have been produced in the material, as by a final annealing operation, but before a final cold working operation reduces  the material to finished  size.   The latter  operation  embeds  or  includes  the lubricant  into  the  material  and  thereby  provides  a  superior lubricated  steel  for piston ring,  shaft,  valve  stem,  spring, stranded wire and the like applications.  The technique involved may also employ corrosion inhibiting agents to increase resis-tance  to  corrosion  of  the  steel  as  well  as  to  improve  its lubricity.

Abstract: ABSTRACT OF THE DISCLOSURE A multistrand winding apparatus has a strand guide fixed to a cam follower of a traverse cam for winding a strand package on a winding collect.  To improve the quality of the strand package, the strand guide is maintained at a spacing from the periphery of the strand package during the winding operation while maintaining an improved package edge weave, and a winding program stored in a programmable memory is employed for controlling the displacement of the strand guide away from the winding collect as the winding of the strand package proceeds.  For simultaneously winding a plurality of strand packages, a corresponding plurality of coaxial traverse cams may reciprocate respective strand guides while being likewise displaced from the winding collect.  The winding program is also used to control the speed of the winding collect and the traverse cam or cams.

The corrections can take into account (a) ship north-south acceleration, (b) change in Coriolis acceleration, (c) earth rotation rate and (d) azimuth error for east-west speed.  Furthermore, account can be taken of the constant characteristics of the particular gyro compass to be corrected in terms of its tilt limit, its period of damped oscillation, its damping and the characteristics of the compass electrolytic level which determines tilt.

Abstract: PARTICULATE FEEDER SYSTEM             ABSTRACT OF THE DISCLOSURE          An agricultural particulate feeder controls the  rate of particulate  distribution  to  a  surface being  worked.   The  particulate  feeder  comprises  a hopper with a sliding door over a discharge outlet at a  lower  end of the hopper.   A  frame  supports  the particulate   feeder   and  has   an  elongated   tube extending longitudinally under  the discharge  outlet of the hopper,  the tube  forming an element of the frame.  A particulate metering cylinder is positioned between  the  outlet  and  door  of  the  hopper  and  a particulate  inlet  in  the  elongated  tube  and  is rotatably  mounted  on  a  drive  shaft.   A  housing encases   the   cylinder   and   forms   an   enclosure connecting the hopper outlet and the tube inlet.  One side of the housing  is  removable  to allow  lateral access to the metering cylinder inside the housing.    In addition, longitudinal removal of the drive shaft permits lateral removal of the metering cylinder from the housing.  The frame is movably supported on the ground and has a mechanism to rotate the particulate metering cylinder and a fan to force air through the elongated  tube  to  provide  a  fluid  medium  for transporting particulate away from the hopper.
