Abstract: ABSTRACT Printing apparatus is disclosed which has a rotatable platen with a printing element in front of it, lower and upper platen feed rolls and a platen drive for rotating the platen upwardly relatively to the printing element.  The apparatus is operable to feed, from an upper hopper extending upwardly and rearwardly from the bottom of the platen, an unprinted sheet to the bottom of the platen and forwardly and upwardly to the front of the platen into printing position.  This is done by means of a bail switch operable upon movement of the upper platen feed roll away from the platen to cause the platen to rotate upwardly to move the leading edge of the unprinted sheet into printing position.

Abstract: ABSTRACT           A novel push-type wire terminating apparatus com-prises an outer casing having a hollow section within and a movable body loosely coupled with the outer casing in the hollow section.  The outer casing has a recess in the hollow section corresponding to a protrusion of the movable body,and elastic means disposed therein for engaging the protrusion in position at one end so as to make the movable body be able to slide up and down in the hollow section. At least a pair of conductors are fixedly arranged in the hollow section at one end and loosely coupled with the movable body at another through a wire guide opening there-in.  When making wire termination, press down the movable body, insert the prepared wire end from a passage on top of the movable body and let it pass through a wire hole on the conductor until it reaches at the end.  Releasing the pressure applied on the movable body, the wire ends will be firmly secured to the conductors thereat and the termination is completed accordingly.

Abstract: ABSTRACT          Two elongated metallic profiles each formed with two pairs of flanges each of which forms a longitudinally extending groove are positioned with the two grooves of each profile parallel and opening toward the two grooves of another such profile.  An elongated bar of insulating material hav-ing a pair of longitudinally extending sides is fitted between each groove of each profile and the corresponding groove of the other profile.  This forms a longitudinally extending passage defined on two opposite sides by the two insulating bars and on the other two sides by the two profiles. A tool is displaced through this passage so as plastically and permanently to deform the inner flanges outwardly and into intimate tight contact with the bars.

Abstract: ABSTRACT      Livestock spraying apparatus has a chute formed by oppo-site sides and a roof, and a chassis frame supporting the sides.  Spraying jets are disposed centrally of the chute.  A filter tank formed with a number of sectors is formed inte-grally with the central area of the chassis frame and has a perforate grating extending over it, and a holding tank is formed integrally with the chassis frame at one side of the filter tank.  Spray solution missing or dripping from the animals is filtered in the filter tank sectors and flows to the holding tank from which it is recycled to the flow of spraying solution passed to the spray jets.  The filter tank arrangement efficiently removes extraneous matter and col-lects the majority of the solution not carried out of the apparatus on the animal, and permits efficient recycling of the spray solution.

Abstract: ABSTRACT OF THE DISCLOSURE:         A continuous casting mold assembly has a pair of end plates which are releasably clamped between a pair of side plates and cooperate with the same to define an open-ended mold cavity.  A single tie-rod at either end of the pair of side plates spans the side plates and provides a clamping function and an alignment function.  Clamping is accomplished by clamping nuts on the tie-rods and the torque required to turn the nuts is maintained at a low value by means of thrust bearings.  Alignment is achieved via tongues on the tie-rods which contact the side plate to be located at the neutral axis of the continuous casting apparatus.  The tongues cooperate with locator heads on the respective tie-rods to define a predetermined distance of such magnitude that the side plate contacted by the tongues lies at the neutral axis when the locator heads about fixed reference elements on the mold table.  The invention provides simplification and increased operational reliability.

Abstract: ABSTRACT OF THE DISCLOSURE An audio processing system for maximizing the efficiency of transferring audio frequency signals.  Signals to be processed are supplied to a bandpass input filter, thence to a primary active frequency control.  Its output drives a primary voltage compressor selectively limiting audio dynamics to a predetermined window, The latter being con-trollably preset and driven with different audio bands of amplitude determined by the primary frequency control to maximum compression levels indicated by a visual indicator. The output of the primary compressor is presented to a secondary active frequency control driving a secondary dynamic compressor with different audio bands.  A second visual indicator indicates maximum compression levels of the latter.  An automatic gain control (AGC) tied to the secondary compressor supplies feedback to the primary volt age compressor via AGC circuitry to control primary compression as a function of average, overall dynamic compression of the system.  The AGC circuitry also feeds a third visual indicator which displays average compressed output voltage.  The processed output of the secondary compressor is provided to a bandpass output filter and, sharply frequency attenuated by the latter, is delivered for further use.  A high level output stage is also selectively utilized for driving auxiliary devices.

Abstract: ABSTRACT OF THE DISCLOSURE    A mill or crusher useful for crushing and grinding material employing mechanical vibratory drive force at a sonic frequency.          A drive shaft having orbiting eccentric weight means fixedly attached thereto is rotatably driven by a drive motor to generate quadrature related vibratory force components in the drive shaft.          Rotatably supported on the drive shaft by means of suitable bearings is a driving member having mass (inductive) inertia in said sonic frequency range.  A "slave" member is freely supported on vibration isolation members in external concentricity with the driving member so that it is effectively in a "floating" condition, thus presenting a mass reactance in said sonic fre-quency range.  Material to be milled or crushed is fed in the gap between the driving member and the free-floating "slave".          Cycloidal force is delivered from the shaft to the driving member to precess or roll around on the inside wall of the free floating slave member.  Vibratory energy developed in this gap effects grinding or crushing action on the material fed therebetween.          The reactive force between the inductive driving member and the slave member is dependent upon the mass reactance of the slave member and the nature and quality of the material in the gap between these two members which affects the sonic coupling be-tween reactances of the free floating driving and free floating slave members.  Thus, the vibratory energy to which the material is subjected is a function of the driving inertia of the driving member, of the hardness of the work material and the mass (induc-tive) inertia of the slave member, the force applied to this work material being limited by these three factors.  Thus, we have a sonic frequency radial vibratory force acting on the material in the gap along with a crushing force provided by the precessional motion of the slave member around on the driving member, this precessional motion resulting in a shear crushing force.

The check valve there-by relieves the pressure in a fluid lock which is formed by a piston and cylinder mechanism the cylinder of which is normally kept closed by the check valve and the pis-ton of which is connected to the valve member of the main valve, whereby said valve member will be moved 1a to closed position by the action of a pressure spring when the check valve is opened. A reduction of the pres-sure in the space between the double conduits results in the spring moving the piston and the main valve member connected thereto towards closed position, thereby giv-ing rise to a fluid flow through a one-way restrictor which is thereby opened and propagates the pressure caused by the spring to the control piston, whereby the pilot controlled check valve relieves the pressure in the fluid lock formed by the piston and cylinder mechanism.     1b
