Abstract: DETACHABLE SHOE PLATES FOR LARGE DIAMETER DRILL BITS     Abstract of the Disclosure Shoe members and drill shank members for large diameter cable drilling bits are provided with a tongue on one of the members that projects axially relative to the drill shank member and with an arcuate lip and projecting stop on the other of the members to trap the tongue and prevent radial movement of the shoe member in response to radially directed forces caused by the spinning of the bit in drilling opera-tions.  Such forces would impose shear stresses on the fastening members that extend through the shoe member and axially into the drill shank.  Four embodiments are dis-closed:  a spudding bit, two star bits and a scow bit.

Abstract: ULTRASONIC WELDING CONTROL          Abstract of the Disclosure A method and apparatus for controlling ultrasonic welding and determining whether the weld is of acceptable quality.  Power input to ultra-sonic welding apparatus is detected and converted to a signal indicative of energy input.  When power input exceeds a power threshold level a timer begins to measure elapsed time and energy input begins to be monitored.  Welding power is terminated when both elapsed time and energy level have exceeded pre-determined values.  If either elapsed time or energy level exceeded reject limit values when the weld was made the weld is rejected as being of unacceptable quality.

Abstract: METHOD AND APPARATUS FOR FABRICATING HONEYCOMB SEAL     Abstract of the Disclosure:        An apparatus  is provided for forming a circular, honeycomb-type engine seal from pre-formed core strip having male and female nodes.  The apparatus include  a source of strip and means for forming the strip into a circular seal configuration wherein the male and female nodes of the strip are automatically juxtaposed to each other for weldment as relative move-ment between the forming means and the source occurs to withdraw additional  strip  from the core strip source.          As the relative movement continues, the juxtaposed male and female nodes are exposed to welding head means of the apparatus which welds the male and female nodes to one another.   The forming means includes means for causing said relative movement constituted by drive means which is adjustable to permit forming means of different sizes to be utilized.  The movement of the forming means permits successive layers or laminae of the strip to be welded to each other in circular form until a seal of the desired dimension is achieved.  The method of the invention involves the step of simultaneously welding a plurality of male and female nodes which are juxtaposed to each other, and the addi-tional step of welding pairs of nodes which are interspersed between previously welded pairs and the further step of utilizing the welding of a selected pair of nodes as a signal for the simultaneous weldment of additional pairs.

Abstract: ABSTRACT     A wash over type down hole retrieving device or fishing tool is described, consisting of a hollow cylin-drical body having an open lower end.  The body has concentric inner and outer walls, defining an annular space in which an annular piston can force down an annular sleeve of a malleable alloy having downwardly extending finger-like formations.  The inside of the lower end of the outer wall is of cupped configuration effective to deflect the fingers inwards and over the open, end of the body so to trap and retain an object for retrieval.  The annular piston is forced down hydraulically by dropping a diverter ball valve.  Cutting teeth are optionally provided on the outer periphery of the lower end of the outer wall, on a detachable shoe.

Abstract: ABSTRACT:           In order to control subscriber access to selected television programmes in a CATV system, non-standard hori-zontal synchronizing pulses are generated (13, 15, 17) having a greater amplitude and either higher or lower pulse repetition rate than the contained horizontal synchro-nizing pulses.  These are selectively added (19 ... 23, 27 ... 33) to those television programmes to be controlled.          As a result, the television receiver of a nonpaying sub-scriber interprets the non-standard pulses as being valid horizontal synchronizing pulses thereby preventing the receiver from synchronizing its line scanning with that of the television programme, rendering picture produced therefrom unviewable.

Abstract: Abstract of the Disclosure A washing machine includes a washing tub whose peripheral wall is constituted by an upper peripheral wall section and a lower peripheral wall section which is located below the upper peripheral wall section and which is driven to rotate clockwise and counterclockwise.  The washing tub receives water and laundry therein.  In the case of a small load of laundry, the laundry is caused to flow, and to be washed due mainly to the flow or water caused by the rotation of the lower peripheral wall section.  In the case of a large amount of the load of laundry, the laundry can be washed due to the synergetic action of the frictional forces.  In such a washing machine, the inner surface of the upper peripheral wall section is made gradually smaller in diameter from its lower portion to its upper portion.

Abstract: Abstract:          An oil heater has a wick fed radiant burner which comprises a wick adjusting shaft rotatable it first and second directions about its longitudinal axis.  A wick holder moves with the wick between an extinguishing position and a maximum combustion position past a minimum combustion position in response to the rotation of the shaft. A ratchet wheel is mounted on the shaft for displacement axially of the shaft. An actuating pin is mounted on the shaft to be angularly movable with the shaft.  An abutment bank is provided on the wheel for defining the angular distance over which the pin moves, which angular distance corresponds to the distance of movement of the wick holder between the maximum combustion position and the extinguishing position.  A one-way stopper on the wheel permits the pin to pass during rotation of the shaft in the second direction, but restrains the pin from passing during rotation of the shaft in the first direction, thereby defining the minimum combustion position.  The pin once restrained can be released from the stopper when the shaft is rotated in the first direction by the application of an external rotary force sufficient to cause the pin to displace the wheel against the biasing spring while permitting the pin to pass over the stopper.  The arrangement provides improved and safer wick operation.

Abstract: ABSTRACT OF THE DISCLOSURE The device includes an open topped housing, the bottom of which is interconnectable to a vehicle steering column through an adapter plate. A biasing plate is slideably supported in a horizontal position in the housing on a number of spaced vertical posts secured to a base plate in the housing. The biasing plate bears a number of spaced ridges extending up from the periphery thereof and defining peripheral recesses therebetween. A horizontal ring locking plate is fixed to the top of the posts above the biasing plate and bears spaced teeth defining a number of notches therebetween with the teeth partially overlying the biasing plate ridges. Coiled springs on the posts push up the locking plate. A lever secured to the biasing plate is needed to selectively move that plate down from the locking plate. A keylock in the housing extends out therefrom and releasably locks the biasing plate up against the locking plate. The device also includes an inverted cup-shaped steering wheel hub connector cap which has on its underside a central plate bearing peripheral projections matching the notches in the locking plate. The connector cap can be pressed down through the locking plate to depress the biasing plate sufficiently to permit rotation of the steering wheel and cap plate to positively lock the projections in the biasing plate recesses below the locking plate teeth.
