Abstract: POT CONSTRUCTION FOR OIL BURNER                   ABSTRACT OF THE DISCLOSURE A pot construction for an oil burner is disclosed which is capable of effectively preventing the leakage of fuel oil through the connection between an oil supply pipe and a pot to the outside of the pot.  The pot construction includes a protective pipe extending between a housing and the pot received in the housing and inserted into the pot, through which the oil supply pipe is inserted into the pot with a gap being defined between the oil supply pipe and the protective pipe.  The protective pipe is formed with at least one through-hole, so that a part of air in an air passage may be introduced via the through-hole and the gap into the pot to prevent the adhesion of soot and tar to the oil supply pipe and the leakage of fuel oil.  An oil burner having such a pot construction incorporated therein is also disclosed.

Abstract: ABSTRACT: Remote control system comprising a control member comprising a display field and position sensing means which are coupled thereto.           A remote control system for the selective control of a plurality of user apparatus. The remote control system comprises a control mender and a control device. The control member comprises a display field and position sensing means which are coupled thereto. Under the control of the control device, control keys are displayed on the display field. The control keys are subdivided into two sets, i.e. a first set comprising control keys for the selection of an apparatus, and a second set which comprises a number of groups, each group comprising the control keys for a given apparatus. The user first selects the apparatus to be controlled. This is done by indicating the control key of the first set which is associated with the selected apparatus. The control device ensures that, after the localizing of the indicated position by the position sensing means, the group of control keys which is associated with the selected apparatus is displayed on the display field.

Abstract: Abstract A connector for making connections to the post of an automotive lead-acid battery is disclosed.  The connector includes a body portion having a pair of bifurcated ring portions each defining a circular opening therethrough, and a locking ring portion, also defining a circular opening therethrough with a pair of lugs affixed to the locking ring.  The circular openings of each are designed to slip over and surround the battery post and when the locking ring is turned by means of the lugs, the lugs come into contact with the ring portions of the body causing the three rings to cut into the battery post around its total circumference by cam action and to lock in position by friction.

Abstract: Abstract of the Disclosure An extrudate suitable for improved gas/liquid contacting is made from a solid, transitional alumina.    The cylindrical extrudate has a partially hollow interior and internal reinforcing vanes or ribs extending from the inner wall to the center of the extrudate particle.  This extrudate configuration permits the extrudate to have the large geometric surface area per reactor volume yet, because of the openings inside the extrudate, the particles do not exhibit a large pressure drop when packed in a deep bed.  One or more Group VI and Group VIII metals can be impregnated to form a catalyst which provides superior desulfurization and demetallization activity than do similar size particles.

Abstract: Abstract As a signal seeking tuner tunes through a number of channels to locate the next active (useable) channel, the display screen of a television receiver is blanked when the receiver is tuned between channels or to an inactive (unuseable) channel for which video signal information is substantially absent.  Superimposed over the blanked screen background is a moveable tuning indicator bar, the position of which indicates the channel to which the receiver is tuned.  The blanking of the screen prevents the tuning indication from being obscured by background noise.

Abstract: Abstract of the Disclosure The present system is comprised of an elongated member which has a finger like protrusion and a cam protrusion both of which are disposed close to one end thereof.  The elongated member has an elongated slot at one end which fits over a stud and is further rotationally coupled to a crank so that the elongated member can pivot around said stud in a number of different positions in response to the crank being moved.  The crank is rotationally coupled to a cam follower and the crank is further arranged to rotate about a stud.  When a tape leader from a take up reel is to be joined to a tape leader from a supply reel, the elongated member is moved toward the tape leader from the take up reel and the finger like protrusion enters a first slot in the take up reel leader and moves that leader to an extended position whereat the cam protrusion cams a tab on the end of the take up reel leader away from the elongated member.  The tab is formed to have a stem section.  The supply reel leader which is extended has a locking slot therein which has a first section which fits over the tab.   In response to said camming action, the elongated member is moved such that said cam protrusion cams said tab deeply into said locking slot and said tab becomes locked in a narrow section of said locking slot.
