Abstract: 1470653 Making bottom folded bags; seaming NATIONAL PETRO-CHEMICAL CORP 6 June 1974 [1 May 1973] 20676/73 Headings B5D and B5K In an apparatus for forming bottom folded bags, Fig. 14, lower and upper grippers 56 and 114 which grip a side gussetted bag section at lower and upper side edges GEL and GEU adjacent a sealed end S, are movable at different speeds in the longitudinal direction of the bag section to fold the bottom. The lower grippers are moved faster than the upper grippers when the sealed end S is the leading end, and the upper grippers are the faster when the sealed end S trails. In the embodiment shown the slower moving upper grippers 114 are inclined upwardly in the direction of feed of the bag sections, and bars (160) Fig. 15 (not shown) which are carried with the lower grippers, can lie in the top walls of the bag sections to define edges about which the top walls are folded during the bottom folding. The lower grippers may also carry a spacer (162) Fig. 15 (not shown) to open the gussets. In operation of the apparatus, guides 61 open the gussets in a web which has been subjected to flame treatment and printed on, and guide the lower grippers 56 which are carried by chains 54, into engagement with the lower edges GEL of the web. Heated sealing bars 62 and back-up bars (68) Fig. 1 (not shown) which are mounted between respective conveyor chains 64 and (70) Fig. 1 (not shown) for movement with the web, then transversely heat seal the web at spaced intervals. Adjustable pressing bars (76) Fig. 8 (not shown) are provided behind at least the heated sealing bars 62. The bag sections are severed from the sealed web by a rotary cutter and opened by a blast of ionized air from a nozzle 98 to facilitate the gripping of the upper edges GEU by the grippers 114. After the bottom folding, brushes 144 deaerate the bags prior to the bags being pressed by pressing belts (148, 157) Fig. 2 (not shown). The finished bags are stacked and the resulting bundle wrapped.

Abstract: The disclosure describes a thermal density sensor for preventing the start-up of a compressor motor operatively connected to the piston and cylinder means of a compression mechanism when the temperature of the compression mechanism is below a predetermined value to prevent damage to the running parts of the compression mechanism due to inadequate lubrication. Control circuitry for operating the compressor motor is contained in a single control box on the compressor so that the wiring of the circuitry is simplified. The control circuitry is entirely factory wired and the circuitry is maintained in a tamper-proof environment.

Abstract: BRAKE APPARATUS AND METHOD An apparatus and method for braking a rotating member in which braking force for retarding rotation of the rotating member is transmitted through an arrangement including a mechanical linkage and a fluid pressure cylinder while a sensor detects the rate of retardation of the rotating member and signals the occurrence of a rate of retardation in excess of a predetermined rate.  In accordance with the present invention, relieving force opposing the braking force is applied to the mechanical linkage in response to a signalled excessive rate of retardation, thereby relieving the braking force otherwise retarding rotation of the member.

Abstract: A process is disclosed for preparing an iron workpiece containing at least 0.03% by weight carbon for a direct-on, one-fire ceramic or enamel coat. A substantially continuous layer of substantially pure iron is pressure-bonded onto a surface of the carbon-rich iron workpiece. Thereafter, the workpiece and bonded iron layer are placed in an electroconducting liquid medium and, while using the workpiece as an anode, some of the deposited iron is electrolytically removed to produce an exposed, fissured, textured surface in the pure iron layer. When a ceramic coat is conventionally applied over the fissured surface, it adheres well, even though the iron workpiece may contain appreciable amounts of carbon which normally prevent such adherence for a direct-on ceramic coat. Optionally, the pressure-bonded layer may be followed by an electrodeposit of a porous, substantially pure iron layer prior to applying a ceramic coat.

Abstract: In a church organ the motion of the key is transmitted to the play valve by means of a direct connection making use of long, narrow wooden laths, so-called abstracts, wherein the motion is transmitted into a different plane via angle pieces. These angle pieces are mounted on an angle beam, and the invention offers the possibility of automatic individual adjustment of each transmission arrangement from the key to the valve in that the angle pieces are suspended in a suspension arrangement which normally takes up a particular position on a mounting axle by spring-tensioning of a plurality of such arrangements against each other, between which friction disks are preferably present, but when it is desired to adjust one or more individual angle pieces the spring tensioning is relieved by means of a lever, whereupon the angle pieces are automatically adjusted to the correct position by virtue of a balanced counterweight action. <IMAGE>

Abstract: A controlled current inverter system forms the basis of an a.c. motor drive system for furnishing the motor load with a variable frequency, variable magnitude a.c. current from an inverter which is supplied from a variable d.c. current source by way of a d.c. link including an inductor. Torque is the control parameter employed in the system and the motor speed and torque are controlled through the control of motor flux and motor current, by maintaining a controlled ratio between the direct and quadrature motor currents, through separate control paths to the d.c. source and the inverter. A third control path functioning on the difference between the desired and actual motor flux serves as a modifier to the main control paths to improve overall operation and control. Means associated with the basic control paths provide for dynamic braking of the motor.

Abstract: Electrophotographic medium which comprises a transparent substrate, ohmic layer and coating of photoconductive material, all of which form a modulating structure for the radiant energy that is adapted to be projected through the substrate; a dielectric layer (storage medium) intimately bonded to the surface of the photoconductive coating and a conductive electrode in intimate contact with the dielectric layer. The structure is used by connecting a d.c. voltage across the outer electrode and the ohmic layer and projecting the image onto the electrophotographic medium from the bottom surface of the substrate. The charge image appears on the dielectric layer. The charge image is read out with an electronic beam or toned and fixed or transferred. During use the electrode is brought into intimate contact with the dielectric layer and removed after forming the charge image in order to enable the medium to be processed further without the electrode. The interface between the dielectric layer and electrode preferably is liquid, at least when originally formed, and may comprise a conductive fluid or organic or inorganic material or a low melting point metal that is easily stripped off the dielectric surface.

Abstract: In the manufacture of non-returnable packages for milk and other beverages the laminated packing material is sealed to itself along linear sealing zones by causing outer thermoplastic layers of the packing material to fuse together. The strength of the seal obtained depends upon the thermoplastic surface being free of impurities, e.g. oxide coatings or residues of the contents of the package. In spite of the presence of impurities a strong seal can be obtained if the thermoplastic layers, within a limited region of the sealing zone, are pressed against each other with such a force that molten thermoplastic material is made to flow to adjoining regions (15), since in this case the thermoplastics are blended to such a degree that the seal-preventing layer of impurities is broken.
