Abstract: ABSTRACT             A machine having a housing wherein are arranged a ham-mer piston adapted for reciprocation in said housing to effect forward and return stroked, and a stepped pressure difference ring valve fitted over the hammer piston and also reciprocating in said housing.  A tool rotation mechanism kinematically linked with a gear mounted on an anvil has at least one twin hydraulic cylinder comprised of two different diameter cylinders loca-ted at the front portion of the machine.  The twin hydraulic cylinder is divided by a lateral partition and accomodates a pusher piston which carries a spring-loaded pawl and forms with the partition and the different diameter cylinder barrels two chambers, the smaller diameter chamber being the pressure one, the larger diameter chamber, the return one.  Adjacent the ring valve having an outer annular groove, the machine hou-sing is provided with three inner annular grooves with pas-sages, of which the front groove, as in the direction of dril-ling, is continuously in communication with the atmosphere, the middle groove is continuously in communication with the larger diameter chamber, and the rear one, with the lower diameter chamber of the twin hydraulic cylinder and with the pressure pipeline.  The above grooves of the housing and the chambers of the twin hydraulic cylinder communicate in such a manner that recipercations of the ring valve causes the pusher piston to effect the forward and return strokes thereby kinematically interacting via the pawl with the gear during the return stroke of the hammer piston.

Abstract: ABSTRACT     A high speed method and machine for imprinting coding indicia on articles travelling in a line along the upper reach of a conveyor at an imprinting zone.  The containers travel to the imprinting zone through a worm feed.  Gripping force is applied to the containers at the imprinting location to immobilize same momentarily during imprinting.  A pivotally mounted inking and printing assembly, including a multiple head printing wheel, is employed and is raised and lowered as a unit without stopping the machine. A single motor drives the machine but each member of the ink supply and transfer means of the inking and printing assembly may have relatively different circumferen? speeds of rotation.  The ink applicator thereof operates at a variable speed independently controlled selectively to vary the quantity of ink applied upon each rotation of the receptor ath therefor.  The speed of the conveyor is controlled in relation to the number of printing heads on the printing wheel.

Abstract: ABSTRACT OF THE DISCLOSURE           This specification discloses an improved worm mixer for a container, which reduces the deposit of material on the inside wall of the container.  This is attained according to the invention by the arrangement that at least part of the outer marginal portion of the worm is provided with one or more wires or bands which are secured in the vicinity of the superficies of the worm.  These wires or bands cut loose doughy or pasty material clinging to the wall, whereby a smaller propulsion of the material in an upward direction along the wall is attained.          Furthermore the cutting edges reduce the dimensions of the deposit on the container wall to a minimum, while the wall effect on the material itself is reduced by the regular severance of the material on the wall from that in the other part of the con-tainer, which particularly may be of importance when operating with pasty substances.  The cutting edges also have likewise a clod breaking, clod cutting effect, respectively on the material which is elsewhere in the container.

Abstract: Abstract An adjustable drop nipple is disclosed for installing fire protection sprinkler systems which comprise sprinkler head assemblies of the pendant, dry drop variety.  The down-wardly extending length of a drop nipple having a sprinkler head thereon is adjusted to achieve a desired length by means of a threaded connection between the nipple and a collar that interconnects the nipple with a supply line for a fire extinguishing fluid such as water.  Accordingly, the drop length of the nipple is adjusted by screwing it into or out of the collar.  Leakage of fluid between the walls of the collar and the nipple is prevented by use of one or more O-ring seals.  Advantages provided by the present drop nipple assembly include the ability to adjust the drop length from below the ceiling line, pressure testing of the system prior to installation of the ceiling, and adjustment of the drop length subsequent to pressure testing, after in-stallation of the ceiling, and under pressure.  In another embodiment the downwardly extending length of a drop nipple having a sprinkler head thereon is adjusted by sliding the nipple axially in a collet having an externally tapered section that engages an intermally tapered section of a stationary collet holder.  When a selected drop length has been established, the collet is compressed axially against the collet holder with tightening means whereby the nipple is firmly gripped by the collet so that axial sliding thereof is prevented, thereby maintaining the nipple at the selected drop length.

Abstract: ABSTRACT OF THE DISCLOSURE      An electronic meter for measuring V2hr in an electrical system includes a center tapped transformer for deriving two analog signals proportional to a detected voltage in the system with the analog signals being 180° out of phase with respect to one another. A comparator compares a relatively high frequency triangular signal with a selected one of the analog signals with the output of the comparator driving a switch which acts as a multiplier.  When a comparison exists the switch couples one of the analog signals to an integrator, and when a comparison does not exist, the switch couples the other analog signal to the integrator.  The output of the comparator is a pulse width modulated signal having a time duration which is proportional to the amplitude of the detected voltage in the system, and the signal coupled to the integrator is a chopped analog signal having an amplitude proportional to the amplitude of the voltage in the system and a time duration proportional to the magnitude of the voltage.  Accordingly, the integrator integrates a signal which is proportional to V2.  At the output of the integrator a signal is generated which is proportional to V2hr.  This signal is converted to a pulse train having a frequency proportional to amplitude of the output of the integrator.  Offset correction is provided by means of up/down integration averaging wherein the input signal to the comparator is switched each time an output pulse is generated.
