Abstract: BCF/srs COMBINED HEADLIGHT, TURN SIGNAL AND PARKING LAMP FOR SNOW PLOWS AND THE LIKE A combined lamp and turn signal for a snow plow or the like comprising a housing which supports a sealed beam headlight lamp bulb and a signal and parking lamp bulb.  The housing has an elongated opening through one wall thereof and a grommet is positioned in the opening. The grommet has spaced flanges which engage the inner and outer surfaces of the portion of the housing defining the opening and extend continuously about the opening.  An outer swivel plate having substantially the same configuration as the outermost flange engaging the outermost flange and an inside plate having substantially the same configuration as the inner flange of the grommet engages the inner flange.  The flanges of the grommet and the inside and outside plates have aligned openings and fastening means extend through the openings.  The inside plate has a portion thereof deformed axially outwardly into engagement with the inner surface of the swivel plate and thereby spaces the inside plate with respect to the swivel plate to provide a predetermined compression of the flanges of the grommet against the edge of the opening in the housing. i.

Abstract: ABSTRACT OF THE DISCLOSURE   The invention is in the field of labelling articles and relates particularly to an apparatus with the aid of which pressure-sensitive labels (6) adhering to a carrier tape (5) can be imprinted and dispensed to be ad-hered to articles.  The apparatus (1) comprises an operating lever (10) for controlling the printing mechanism (14) imprinting the labels (6) and for controlling a feed means (8), which draws the carrier tape (5) stepwise over the platen (15) around a peel edge (7) at which the pressure-sensitive labels detach from the carrier tape (5) and move into a dispensing position.  In the rest position of the operating lever (10) the carrier tape (5) is held by a braking means.  In this kind of apparatus it must be assured that even in a rapid succession of the operating cycles a high degree of accuracy in the imprinting of the labels in the apparatus is attained.  By means a cam gearing (28, 29) disposed between a brake actuating member (21) and the operating lever (10) the brake actuating member (21) is pressed out of the carrier tape clamping position into the carrier tape release position when the operating lever (10) has covered part of its travel from the rest posi-tion towards the operative position while an arresting means arrests the brake actuating member (21) in the carrier release position and is released as soon as the operating member (10) reaches its rest position.  The appa-ratus is used in department stores and supermarkets, where pressure-sensitive labels are attached to the goods or their packaging material, the labels being imprinted with, the article number and a price in the apparatus prior to attaching them.

Abstract: ABSTRACT           A cutter insert presenting eight positive cutting edges has a generally rectangular prismatic configuration to permit its securement in a tool holder having a conventional square insert-receiving pocket.  The insert has a pair of opposed primary faces, and four rectangular side faces each having a pair of coplanar, flat lands in opposite corners thereof to permit positive location and clamping of the insert.  Each side face also has a laterally opposed pair of positive beveled facets formed therein and intersecting the respective primary faces to define neutral cutting edges for the insert.  An elongate groove extends intermediate the beveled facets of each side face parallel to the neutral cutting edges and functions as a   chip breaker to provide freer cutting and better chip control.          In preferred forms, a square pocketed tool holder is complementally configured to advantageously support the cutter insert in a manner to present a negative angle of attack at the work surface.

Abstract: ABSTRACT OF THE DISCLOSURE          Data processing workloads are balanced between a plurality of data processing units, such as control units of a peripheral system, based upon tallies of data processing delays.  The workloads are arranged in work allocations, such as assignment of peripheral devices to a control unit;  a separate delay tally is kept for each work allocation along with a summation of all delays in each control unit.  When a tally threshold in any data processing unit is exceeded, load balance is examined. Upon a predetermined imbalance, a work allocation having a delay tally equal to a mean value of the different delay summations is transferred to a data processing unit having a lower delay summation.

Abstract: Abstract:    A semiconductor integrated circuit for use as a highly dense memory comprises a first circuit receptive to a first power source voltage for generating a predetermined second power source voltage lower than the first power source voltage.  There is also a second circuit receptive to the first power source voltage for generating a second pulse signal for use with the second power source voltage in response to a first pulse signal that varies within the same voltage range as that of the first power source voltage.   A third circuit receptive to the second power source voltage and responsive to the second pulse signal has circuit elements of smaller size than those of the first circuit.  This arrangement enables very dense packing of the elements while avoiding a need to reduce the voltage that can be applied to avoid risk of di-electric breakdown.

Abstract: Abstract of the Disclosure:     In a time division multiple access system comprising a central station and a plurality of substations, a subsidiary analog signal is sampled at a sampling circuit of each substation M times during each frame period to produce a succession of sampled pulses. A group  of M sampled pulses is located by a substation delay circuit in each up-link burst assigned to each substation.          Responsive to an up-link succession including each up-link burst, the central station reproduces the sampled pulse group from each up-link burst into a reproduced group of M reproduced pulses by central station sampling pulses synchronized with the M sampled pulses.  The M reproduced pulses are rearranged by a central station delay circuit into sampled pulse reproductions appearing M times in each frame period.  The sampled pulse reproductions are desampled into the subsidiary signal.  The number of M may be equal to or greater than one.     (Fig. 2)
