Abstract: ABSTRACT OF THE DISCLOSURE           A tiltable frame is mounted on wheels and connects to a tractor or truck by means of a hitch pole assembly pi-voted to the frame just rearwardly of the front end of the frame.  A pair of substantially semi-cylindrical troughs are situated on the frame one adjacent each longitudinal side thereof, to receive round bales lengthwise thereon.  A pick-up is pivoted to one side of the frame near the front end and is movable from a bale pick-up position to a bale transfer position by means of a fluid operator.  As the pick-up moves with a bale through approximately 90° to the transfer posi-tion, the bale rolls from the pick-up to one of the troughs.  If there is no bale on the far side trough adjacent the pick-up, the bale rolls across the first trough to the second trough and is restricted from further movement by a restraining bar on the side of the frame adjacent the second trough.  When two bales are positioned side by side, one in each trough, trans-versely of the pick-up, a push bar assembly moves them rear-wardly along the troughs, a distance sufficient to permit loading two more bales.  When unloading, the frame tilts rear-wardly and the push bar pushes the bales rearwardly from the rear end of the troughs.  The tractor or truck can be in neu-tral so that it is moved forwardly as the bales are ejected from troughs onto the ground.  The tilting of the frame faci-litates the sliding movement of the bales during the unloading action and prevents them from tipping upwardly onto the ends as they strike the ground.

Abstract: O.Z. 32,364/542 ABSTRACT OF THE DISCLOSURE: 3-Halosulfonylthiophene-carboxylic acid compounds are manufactured by reacting 3-ketothiophane-carb-oxylic acid compounds with sulfonic acid compounds, reacting the end product from the 1st reaction stage with alkali metal poly-sulfides, reacting the end product from the 2nd stage with a dehydrogenating agent and finally reacting the end product from the 3rd stage with halogen and water. The products are starting compounds for the manufacture of drugs, dyes and crop protection agents and have an anti-inflammatory, analgesic and anti-rheumatic action. In particular, the end products I are starting materials for the manufacture of sweeteners which are non-toxic and free from an after-taste, flavor-improving agents, diabetic  aids and feedstuffs, and provide the means of a simple and economical syn-thesis of thiophene-saccharins.

Abstract: ABSTRACT OF THE DISCLOSURE     The specification describes an improved defi-brillating and monitoring system of the type having a source of high-voltage defibrillating signals and signal monitoring means for monitoring the signals indicative of heart activity.          The system includes a first electrode system for selectively applying defibrillating signals to a patient and for selectively applying monitoring signals to the means for monitoring signals, and a second electrode system for selectively applying monitoring signals to the means for monitoring signals.  The means for monitoring signals includes a first isolation amplifier.  A switch selectively applies monitoring signals to the first isolation amplifier alter-natively from the first electrode system or from the second electrode system.  The improvement comprises a second isolation amplifier coupled intermediate the first electrode system and the switch means whereby to prevent current leakage between the first electrode system and the second electrode system.  This is particularly desirable in those defibrillating and monitoring systems which are battery powered and have a floating ground, rather than an intentional direct connection to actual ground or earth potential.

Title: Coincidentally selected bubble domain  storage array

Abstract: COINCIDENTALLY SELECTED BUBBLE DOMAIN STORAGE ARRAY                  Abstract A magnetic bubble domain storage system comprising an array of rows and columns of logical chips, individual ones of which can be selected for writing in information or for reading out information.  The logical bubble chips used for bubble domain storage (or logic) are organized into logical half-chips with even numbered bits (bits 2, 4, ...etc.) in one half-chip and odd numbered bits (bits 1, 3, 5 ... etc.) in the other half-chip.  Alternating rows of half-chips are used for storing even numbered bits and odd numbered bits, respectively.  Each half-chip has its own bubble domain generator, but a common generator current line serves all generators for a row of even half-chips and all generators for a row of odd half-chips.           Thus, information is written into even half-chips and odd half-chips at the same time by pulsing the generator current line common to a row of even half-chips and a row of odd half-chips.           Each half-chip has a sensing element and all the sensing elements corresponding to a row of half-chips are connected in series.  The series connection of sensors in any row forms one leg of a bridge circuit, and another leg of the bridge circuit is another series connection of sensors in another row of the storage array.  One of these legs corresponds to sensors from a row of even half-chips while the other leg corresponds to sensors from a row of odd half-chips.  The other two legs of f the bridge circuit are comprised of dummy resistors.  Even though two rows of sensors are connected to the same bridge circuit, even numbered bits and odd numbered bits will be read at alternating times.  By proper pulsing of current carrying lines, used for the read operation, any half-chip out of those in the same row can be selected for read-out.  Information can be written back into the half-chips in the same cycle in which information is read from these chips, by having a connection between the sense amplifiers and the generator current lines.

Abstract: KEY SWITCH ASSEMBLY                           Abstract An electronic switch keyboard for typewriters of office machines includes a multiple switch at selected key posi-tions to provide two signal inputs to a utilization device. A first capacitor switch is actuated to provide a first signal upon initial key depression and a second contact switch, common to all selected key positions, is actuated to provide a second signal upon further key depression at the selected key positions.  A ground plane forms a portion of the contact switch and further serves to reduce parasitic capacitance and to shield the capacitive switches from stray electrical noise occasioned by the contact switch or other electrical inputs.  A dielectric material is used to accurately separate the ground plane from the capacitive switch and further serves as a force spreading device for the contact switch.  When the keyboard is used in conjunction with a typewriter, the first signal may be used to effect character selection and printing and the second signal to effect repeated printing of the same character.  Consistent with prior mechanical typewriter keyboards, three increasing levels of force are required to be overcome as the key is depressed:  a pretravel force, a first switch actuation force, and a second switch actuation force.
