Abstract: WEB WINDING APPARATUS AND METHOD     ABSTRACT       In the high speed rewinder of the present invention a parent roll of paper unwinds from a back-stand to feed a wide web of paper to a perforating means, web separ-ation mean, core-feeding means and log rewind means. The perforating means includes a stationary ledger blade and a rotating knife-blade roll which cut lines of perforations across the web.  The web separation means includes a pair of operatively opposed rolls rotating in synchronism, one or which has a spiral groove therein and the other or which has means arranged to force the web of paper into the groove to tear the web within the groove.  A secondary winder roll is disposed in spaced relation to the first winder roll to define a throat. A core advancing means is arranged, periodically, to bring a core into the throat, which is narrower than the outer diameter or the core.  The secondary winder roll can be slowed down to cause the core to advance through the throat and pick up the leading edge or the web.  A diameter control means is disposed near the secondary winder roll to limit the outer diameter of the finished log or paper with a predetermined length of web being wound on said core.  Control means regulate the rotary speed or the perforation roll, the main-winder roll, the web separation roll, the secondary winder roll, the diameter control roll and the core so that a precise length of paper web will be wound on the core, differential speed between the secondary winder roll and the diameter control roll will move the finished log into a log receiving means and differential speed between the first and second winder rolls will advance another core into the throat to pick up the leading edge of the just-severed web, advancing the core and web through the throat to repeat the sequence.

Abstract: ABSTRACT OF THE DISCLOSURE    A data transmission system comprises a transmitter, a receiver and a repeater coupled to a power line.  Control data including a start code in the form of a high frequency signal is transmitted from the transmitter over the power line in superposition on a commercial power supply alterna-ting current.  The repeater stores the control data in a memory in response to the start code.  The control data is then read from the memory after the lapse of a predeter-mined period of time and is retransmitted to the receiver at a predetermined level to counteract attenuation.  The receiver receives the control data, thereby to control an apparatus to be controlled, such as a relay, whereupon the same transmits in a return manner data representing a control state thereof.  The repeater receives the control state data and transmits the same to the transmitter.

Abstract: ABSTRACT OF THE DISCLOSURE           In producing methacrylic acid, a first step is preferably to acetalate isobutyraldehyde, the acetal thus formed being then broken down into isobutenyl-ether and alcohol, and thereafter the isobutenyl-ether is oxidized with molecular oxygen, or a mixture of gases containing oxygen, in the presence of a leach at temperatures of 30 to 70°C, into an epoxide, said epoxide being hydrolyzed into .alpha.-hydroxyisobutyraldehyde which is then oxidized, with concentrated or fuming nitric-acid at temperatures of 20 to 110°C, into .alpha.-hydroxyisobutyric acid from which methacrylic acid is obtained by dehydration.  This preferred production route utilizes readily accessible feed stocks with simple technical steps to provide good yields of methacrylic acid.

Abstract: TITLE:    TOY ROBOTIC ARM     ABSTRACT          A toy robotic arm is constructed to include a base having a control mechanism therein which in-cludes a single motor.  An operator control member ex-tends from the base and can be manipulated by the opera-tor of the toy.  An articulated arm is attached to the base.  The articulated arm has a plurality of segments which are movably joined together at points of articu-lation.  A grasping member is attached to the end of the arm distal from the base and is capable of inter-acting with objects.  Motion from the motor is trans-ferred to both the segments of the arm and the grasp-ing member by transfer members moving through the arm. The operator of the toy, by manipulation of the opera-tor control member, which interacts with the control mechanism, can cause articulation of individual seg-ments of the arm with respect to one another and move-ment of the grasping member.  Motion of the motor is transferred to the transfer members via the control mechanism in response to the operator's commands input via the operator control member.  The control mechan-ism and the operator control member are constructed so as to allow independent initiation, maintaining or stopping of any motion of the articulated arm or the grasping member independent of any other motion.

Abstract: OBJECTIVE REFRACTOR FOR THE EYE            Abstract of the Disclosure An objective refractor for the eye is disclosed in which knife-edge optics are utilized.  The knife-edge optics cause characteristic illumination of the retina so that components of sphere and astigmatism can be identified. Provision for remote reading of the characteristic images is provided with the result that two orthogonally disposed knife-edge images can identify the sphere, cylinder and axis required for prescriptive patterns giving the direction and magnitude of required prescriptive change.  A system of at least two orthogonally disposed, (and preferably four), knife edges with weighted lighting is disclosed for detection. Utilization of the knife-edge images is made possible by the detection of the low light level images at a detector having low noise level.  A photo-sensitive element divided into a plurality of photo-discrete segments has light from the images proportionally dispersed over its surface.  Such dispersion occurs through a matrix of wedge-shaped segments or alternately in the form of optical elements having cylindrical components.  This dispersion of the light when used in combination with push-pull knife-edge patterns herein disclosed produces detectable low level refractive signal. An embodiment using an optic having a plurality-of side by side optic elements, each element having the effect of crossed cylinders, is disclosed with the detector.  Separate independent and non-interactive positional information on one hand, and refractive information on the other hand, is provided.  Consequently the disclosed refractor is insensi-tive to adjustment and can accommodate a large range of pupil configuration with insensitivity to local retinal variations in light emission.

Abstract: Abstract of the Disclosure Apparatus for sorting and collecting pieces of material, particularly sawn timber, comprises a plurality of collecting chambers, which are arranged in a row and each of which is provided with an in-clined chute and with storing means which are operable in dependence on the quantity of said pieces contained in the collecting chamber. A substantially horizontal sorting conveyor extends above the collecting chambers and discharges sorted pieces of material into the col-lecting chambers. A substantially horizontal taking conveyor for carrying off the batches of sorted and collected pieces of material extends below the collect-ing chambers. In order to permit a fast and functional-ly reliable sorting of pieces of material in any desired number of batches, the collecting chambers are channel-like and an antechamber is disposed between the sorting conveyor and each collecting chamber and opens into the latter. The chute associated with each collecting chamber has an angle of inclination that is smaller than the angle of repose of aggregates formed by the pieces of material. The storing means associated with each collecting chamber comprise a collecting conveyor, which extends along the chute and collects the pieces of material in a layer of substantially uniform thickness.
