Abstract: 47,586 WIRELESS EMERGENCY POWER INTERRUPTING    SYSTEM FOR MULTIBRANCH CIRCUITS     ABSTRACT OF THE DISCLOSURE           A system for the emergency deenergization of a multibranch power circuit includes a ground fault circuit interrupter having capability to trip under both ground fault and grounded neutral conditions.  A plurality of receptacles are provided on the circuit to receive connect-ing plugs of electrical devices to be powered.  A removable plug adapted for insertion into any of the receptacles includes the series combination of a normally open push-button switch and resistor connected between plug pins which are in contact with the neutral and ground conductors of the circuit so that actuation of the switch when the plug is in-serted in a receptacle establishes a low-impedance path from neutral to ground which is detected by the ground fault circuit interrupter.  This causes the interrupter to trip and deenergize the circuit.

Abstract: A B S T R A C T     The invention relates to a Knitting machine having a combing-in cylinder for producing knitted goods with combed-in fibres. The problem of the invention is rapidly and ef-fectively to eliminate the gaps which occur in the carding clothing of the combing-in cylinder in the knitting opera-tion and which have only a very small number of fibers. This problem is solved by means of a regularisation cy-linder which co-operates with the combing-in cylinder and which treats the fibres on the combing-in cylinder in the manner of a comb, displaces such fibres in the opposite direction to the direction of rotation of the combing-in cylinder and thereby regularises such fibres, without however picking up fibres itself.

Abstract: ABSTRACT OF THE DISCLOSURE           Can bodies are sucked by vacuum means onto rotat-ing, disc-shaped vacuum pads which accompany the cans throughout an indexing route.  An adjustable can-centering guide positions each can on the center of one of the vacuum pads to insure eventual alignment with spray guns at two spray stations downstream.  A spinner-drive belt encircles a turret and forms a substantially continuous rotational drive for spinning the can-bearing vacuum pads.  The vacuum means comprises a vacuum manifold in the rear of the turret and has a manifold groove for vacuum communication with the can through the vacuum pad.  As the can-bearing vacuum pads pass along the manifold groove, the cans, being securely centered on the vacuum pads, rotate at the same velocity as the belt-drive vacuum pads.

Granted: 1982-03-16
Abstract: A high speed color reproduction machine comprised of four separate xerographic type processing units, one for each of the primary colors plus black. The multiple processing units are arranged in close nested relationship to one another with the image transfer stations thereof in close succession along the path of movement of the copy substrate material. A combination air flotation type and vacuum based belt transport system is employed to bring copy substrate material from a supply source into transfer relation with the successive processing units. Exposure of the processing unit's photoreceptors is simultaneous. A precise dimensional relationship between photoreceptor length and spacing for each processing unit assures registration of the color images produced with one another. Following transfer of the last color image, the image bearing copy material is brought to a fuser where the image is fixed. The finished copy is thereafter discharged, or returned for a second duplex pass. The photoreceptor of each processing unit comprises an endless photoconductive belt. The length of each photconductive belt is the same. Vacuum tensioning means is employed with each belt to provide preset belt lengths between exposure and transfer stations for each processing unit. A flying spot type exposure system is used with laser light source and optical means to simultaneously project independent image exposure

Abstract: ABSTRACT OF THE DISCLOSURE         A new liquid phase oxidation process in which a metal nitro complex transfers an oxygen atom from the nitro ligand to a substrate; especially such process conducted cyclically or catalytically using molecular oxygen as the oxygen source.  Metal nitrosyl complex is formed as a coproduct together with an oxida-tion product of the substrate.  In a catalytic process, molecular oxygen maintains a concentration of nitro ligand in the reaction mixture.  In a cyclic process, nitrosyl ligand of the metal nitrosyl coproduct is reoxidized by molecular oxygen in presence of a monodentate base such as pyridine to nitro ligand; and the nitro complex, thus regenerated, can be used again to oxidize the substrate.  In particular the metal is a Group VIII metal, espe-cially cobalt and the nitro complex is pyridine cobalt nitro saloph.  To accelerate oxidation of the substrate at given temper-ature, a cocatalyst is included in the reaction mixture, e.g. an organic complex of a transition metal such as Mo(VI), Pd(II), or compound of a trivalent metallic element with an element of Group VII, such as the compound BF3.

Abstract: F. Abmed- 2 DISTRIBUTED CONTROL MEMORY NETWORK     ABSTRACT OF THE DISCLOSURE: A computer-controlled distributed communication system in which there is a system controller and a plurality of group controllers all interchanging information over a system bus. Each group controller has its individual group bus for the exchange of information between stations of the group and the group controller. Each group controller shares a portion of its random access memory (RAM) with the system controller. When information is directed at approximately the same time to the RAM from a group central processing unit (CPU) bus and from the system CPU bus, the first to access the RAM is enabled to feed its information. Neither bus has any preference. The fed information is stored temporarily in a temporary storage or mailbox RAM in the group. Within the mailbox RAM, separate sections are provided for the storage of information for each direction of information transfer. The mailbox RAM is periodically interrogated during regular scans by the respective controllers to determine if information is stored awaiting transfer. An indication of stored information in a section triggers the transmission of information from the mailbox RAM when the destination bus is available. In this way, each processor can continue functioning without the imposition of a hold condition when access to the bus is not possible at that time.

Abstract: Abstract of the disclosure Card Index A card index comprises a housing containing a drawer which holds a stack of punched cards.   All the cards have punched holes in which a row of dogs in the bottom of the drawer engage and the cards also have punched selection holes in which selection stop cams can engage.   Each card has selection holes in register with all of the stop  cams except one.   To select a card, a button corresponding to the card is pressed and this rocks a key lever to move the corresponding stop cam downwards.   The cam passes through the selection holes in all the cards until it reaches the selected  card which has no hole in register with that cam.   Accordingly, the selected card and the cards, if any, below are pressed downwards and are held on the dogs .  The drawer is released by depression of the button and is opened by a spring. As it opens, the drawer moves the cards which are pressed down on the dogs out of the housing with the selected card on top, but the cards above the selected card are retained in the housing by the stop cam. The arrangement has the great advantage over existing card indexes that it is not necessary to arrange the cards in any particular sequence in the stack in order for them to be correctly selected.

Abstract: CONVEYOR DEVICE ABSTRACT OF THE DISCLOSURE An accumulator conveyor is disclosed which can be of either the driven roller or wheel type.  The driving belt providing the propulsion for the conveyor is supported on regulating devices each of which has a rotatable section flanked on each end by a rotatable wheel-like circular feeler. The rotatable sections are circular except for a flattened portion providing an area of reduced radius.  The feelers are spaced apart such that the belt is seated on the rotatable section between them.  A lost motion connection interconnects one or both of the feelers with the rotatable section.  In the case of a wheel conveyor, the feelers contact the articles moving along the conveyor.  When an article becomes stalled over one of the regulating devices, the feelers also stall which in turn, through the lost motion connection, stops rotation of the rotatable section with the flat section upper-most, permitting the belt to drop out of engagement with the article.  When article movement is resumed, the feelers release the rotatable section which then resumes rotation shifting the belt back into drive position.  The operation is the same in the case of a roller conveyor except the con-tact of the feelers and the belt is with the rollers forming the conveying surface rather than with the article.  The regulating devices are resiliently mounted to permit automatic vertical adjustment which is particularly important in the case of wheel conveyors to assure adequate contact with articles having irregular bottom surfaces.
