Abstract: Abstract An electronic hybrid circuit for matching a two-wire telephone circuit to a four-wire telephone circuit is described.  In one embodiment, the circuit includes a variable or adaptive impedance circuit and a first impedance element for supplying a reception signal on the four-wire circuit to a terminal of the two-wire circuit.  A second impedance element is connected to supply the recep-tion signal on the four-wire side through the adaptive impedance circuit and an adder is connected to add, in reverse phase, the reception signal appearing at the junction between the second impedance element and the adaptive impedance circuit to a signal provided from the terminal of the two-wire circuit.  The resultant output from the adder is a transmission signal on the four-wire side which is fed back to a control terminal of the adaptive impedance circuit where-by the impedance of the adaptive impedance circuit varies depending on the characteristics of the two-wire circuit.

Abstract: ABSTRACT     A memory unit  having a  multiplicity of  storage locations  for the temporary storage of series of groups of data signals.  when the data groups  are  being stored  in  a memory location, index  signals are developed that  not only identify  the location of  the stored signal group, but when applied to the memory unit cause the data group to be withdrawn from  the memory unit.  The memory unit is  comprised of a first  addressable  multiplicity  of   storage  locations;  a  second addressable  multiplicity of  storage locations, the  contents of the second multiplicity  of storage locations adapted  for addressing the first multiplicity of storage locations, a counter for addressing the second  multiplicity  of  storage  locations; and  control  logic for controlling the counter  and entry and withdrawal of  data signals in the first  and second multiplicity of  storage locations.  The second multiplicity of storage locations contain  the index signals that are also  the addresses  of the related  data signal groups  in the first multiplicity  of  storage  locations.   As  data  signal  groups  are withdrawn from a first storage location in response to application of index signals,  a second storage  location stores the  address (i.e., the  index signal  of the  first storage location not  available for storage of a data signal group).   The storage of a data signal group with the  concurrent development of index  signals, or the withdrawal of the data signal groups can be accomplished in one clock cycle.  In addition, a simultaneous storage and withdrawal of data signal groups can be accomplished in one system clock cycle.

Abstract: LENS PROCESSING METHOD AND APPARATUS     (Abstract of the Disclosure) A chucking method and apparatus for processing a lens blank in a manner requiring only a single mounting of the blank to an associated lens block. The lens block is mounted to the convex lens blank surface by a hot melt type of adhesive so as to extend outwardly thereof substantially coaxial with the lens blank frame center axis.  The lens blank and lens block are releasably mounted in a chuck associated with lens surface generating apparatus such that the lens blank frame center axis and the tail stock of the generating apparatus are coaxial. The chuck includes means for selectively adjusting and rotating the lens blank relative to the tailstock for accommodating any desired decentration, axis setting and prism prescribed for the finished lens.  Following generation of the desired optical characteristics in the lens blank, the blank and associated lens block are mounted and processed first in surface fining apparatus and then in peripheral edge contouring apparatus.  In these operations, the lens blank frame center axis is disposed substantially coaxial with the associated apparatus tail stocks or chucks.  An adaptor conveniently allows adjusting rotation of the lens blank about its frame center axis in the surface fining and polishing apparatus compatible to any degree of rotation accommodated during surface generation.  Following lens blank edge contouring, the lens block is removed from mounted association with the finished optical lens.

Abstract: BODY WEIGHT CHAIR CONTROL               ABSTRACT OF THE DISCLOSURE           A chair control in which the chair occupant's body weight is the primary source of energy in reclining the chair and returning the chair to its task position includes a back support link and a front link, each pivotally mounted to a base link.  A seat support link is pivotally mounted to and between the front link and the back support link.          Pivoting of the links is restrained so that the front link extends upwardly and forwardly from said stationary link.          The occupant's weight exerts a downward force on the front link, which exerts a forward force on the seat support link, which in turn exerts a forward force on the back support link providing a task position chair back support.  A rearward force exerted on the back support link, as when the occupant reclines is partially counterbalanced by the above described forward force on the back support link so that no additional biasing means are necessary.  The preferred embodiment includes biasing means to return the unoccupied chair control to the task position.

Abstract: Abstract of the Disclosure:     An equalizer of a transversal filter type is given a substantially constant gain at a preselected frequency (fp) in a predetermined frequency band of an input and an output signal.     For this purpose, the output signal is given by multiplying the routine transversal filter output by a reciprocal of an absolute value of a sum of complex tap gains (Cl to CN+l).  Alternatively, the input signal and successively delayed signals (IN and Dl to DN) may be multiplied by the reciprocal before summation.  It is possible to approximate the reciprocal by omitting those of the tap gains which are near both ends (as Cl and CN+l).     (Fig. 2)

Abstract: ABSTRACT OF THE DISCLOSURE         A permanent mold, particularly a metal mold, has a gap between the shell and a feeder insert for attaching the feeder insert on to the casting.  During the casting process, the liquid metal penetrates into the gap and hardens promptly.  The thin bushing which is thus formed creates a solid connection between the casting and the feeder or feeder insert.  Thus, the casting can be removed earlier from the mold.

Abstract: ABSTRACT A pneumatic run-flat insert for a pneumatic tire is provided with circumferental sections having different radii. During vehicle operation in a run-flat condition the different insert radii cause a vibratory disturbance at a wheel axle that alerts the driver of the existence of a run-flat condition or an abnormally low-pressure condition in the tire. During normal driving conditions there is clearance between the insert and the tire liner and no warning vibrations will occur in the wheel axle.     In various embodiments of the invention the different insert radii correspond to two or more ply sections in an insert ply having different cord angles. A relatively high cord angle ply section will furnish a relatively larger radius than the ply section with a rela-tively low cord angle.     In further embodiments of the invention a pneumatic or non-pneumatic run-flat insert includes one or more bumps on the insert crown formed of rubber strips for example that furnish the insert with an out-of-round condition that causes a similar vibrating disturbance to warn the driver of a low-tire pressure or run-flat condition.

Abstract: Title of the Invention Microwave oven with rotary antenna Abstract of the Disclosure A microwave oven with a rotary antenna for feeding electromagnetic waves to a heating chamber.  The antenna has a first antenna portion and a second antenna portion which extend in mutually opposite directions and substan-tially at right angles to a rotary shaft portion, the length of the first antenna portion being greater than that of the second antenna by approximately one quarter of the wavelength of the electromagnetic waves used and the free end of the first antenna portion being bent substantially at right angles thereto for a length not exceeding one quarter of the wavelength to thereby ensure a uniform electric field dis-tribution within the heating chamber.  A dielectric seal plate supporting the rotating shaft of the rotary antenna has a tapered cross-sectional configuration projecting into a waveguide to prevent a sharp change of impedance in the waveguide, whereby spark discharge due to a high-frequency electric field is effectively prevented even in the absence of a heating load in the heating chamber.
