  • Patent number: 4819931
    Abstract: A compact sorting machine inverts recorded sheets into a face-down attitude and discharges them into individual trays. When a recorded sheet is sent from a feed opening, this sheet is transported on a transport path located below entrances of a plurality of trays. Guide members disposed in the vicinity of each tray entrance are driven according to a control signal so that the recorded sheet is discharged into individual trays. At this time, a guide member having an arc-shape simultaneously inverts the recorded sheet into a face-down attitude.

  • Patent number: 4818125
    Abstract: Disclosed is an electronic typewriter with a word correction function substantially consisting of a print data memory, a correction word memory, correction determination means, selection means and correction control means. If a correction word is too long to be printed in place of an erased wrong word, the selection means is driven to select a least number of neighboring words to be erased. The correction control means controls the pitch of the correction word and its adjacent spaces before and after the word. Since the correction range can be extended to the right and left margins, a relatively long word can be automatically substituted for the erased wrong word.

  • Patent number: 4818131
    Abstract: A typewriter having a function of automatically indicating a candidate correct word for a misspelled word and, including a control device operable upon operation of a suitable key for checking entered words against data stored in a dictionary memory to find any wrong word; and if any wrong word has been found, for searching for at least one candidate correct word for the wrong word from the words stored in the dictionary memory; and for displaying the candidate correct word in relation to the wrong word. In place of, or in addition to the above function, the typewriter may have a function of automatically correcting a misspelled word, with the control device being operable upon operation of another suitable key, for activating erasing and printing mechanisms to erase at least wrong characters of the wrong word and print correct characters to correct the wrong word, according to the data representative of the wrong and correct words.

  • Patent number: 4819015
    Abstract: The anti-theft product rack continuously monitors the weight of the rack including individual product units. When a weight deviation is detected, it is characterized as either a disturbance or as the removal of one or more product units. An alarm is sounded if the rack is continuously disturbed for a programmable number of continuous weight sensing cycles, or if a programmable number of disturbances occur during a programmable period of time. In addition, an alarm is sounded if the number of product units detected as being removed at one time exceeds a programmable limit. Finally, if the number of detected product units removed exceeds a programmable number during a programmable period of time, an alarm is sounded. The product display rack presents no physical barriers to product removal and requires no intervention of sales personnel for product removal.

  • Patent number: 4819093
    Abstract: A rotary magnetic recording-reproducing apparatus in an electronic camera system, wherein a subject is purely electronically still-photographed and recorded on a rotating magnetic disc, and the reproduction of an image is carried out by a television set or a printer. When the tracking operation is performed up to the final track and the recording track cannot be detected (an envelope cannot be detected), a warning is issued on the basis of this fact so that loading of an unrecorded disc can be detected. Furthermore, when a track having a number other than one of the numbers of reproducible tracks is to be reproduced, a warning is given so that an operator can be informed of the fact that an unreproducible track has been reached.

  • Patent number: 4818425
    Abstract: A process for the preparation of agglomerates containing diperoxydodecanedioic acid and a water-impermeable material, e.g. lauric acid, which process comprises the successive steps of agitating an aqueous suspension of the peroxy acid in the presence of the water-impermeable material and above the melting point thereof, cooling the suspension of the agglomerated particles thus obtained to a temperature at which the water-impermeable material turns solid, and isolating the resulting agglomerates. The agglomerates obtained are suitable for use as bleaching agent.

  • Patent number: 4818206
    Abstract: The inside surface of an extrusion cylinder (1) is divided into an upper surface (2) and a lower surface (3), each in the shape of an arc of a cylinder. The two surfaces intersect so that two screw sections (8, 9), each provided with a helical thread (12, 13), mesh with each other. The two threads are complementary in that the width of one thread (12 ) gradually increases from an entry opening (6) downstream, while the width of the other thread (13) decreases gradually from the upstream end toward the exit opening (7). Owing to separations between the free spaces, the material poured into the extruder through the entry opening is forced to pass once into a working zone in order to reach an exit chamber where the pressure is less than in the entry chamber.

  • Patent number: 4817362
    Abstract: The invention enables two-way communication to be established between a measuring probe on a machine spindle and the machine using only two wires between the probe and the machine. Communication from the probe to the machine is achieved by causing current changes in an electrical circuit within the probe (due to the probe circuit changing state when a workpiece is detected) to be sensed by a current sensing circuit on the machine to produce an output in the machine circuit indicative of workpiece detection. Communication from the machine to the probe is achieved by varying the voltage supplied to the probe circuit under the control of the machine controller, the change in voltage being sensed by components of the probe circuit to initiate different functions of the probe circuit e.g. re-setting the probe or changing the gain of a component.

  • Patent number: 4819024
    Abstract: An image-forming apparatus of a type which has an exposing device for forming latent images on a photosensitive medium, and a developing device for developing the latent images into a visible images. The photosensitive medium is supplied in the form of a web from a supply roll, along a feed path which extends through the exposing and developing devices. A shearing device is provided between the exposing and developing devices, to cut the web into cut sheets each of which has a predetermined length including an image-wise exposed length. After each cut sheet is parted from the web, the web is fed back until its leading cut end reaches the developing device, so that each portion of the web following the cut sheet can be used.

  • Patent number: 4817597
    Abstract: A self-contained closed-circuit oxygen-generating breathing appratus is provided with a partition wall disposed in such a manner as to oppose at least the lower portion of the inner surface of a breathing bag. The partition wall partitions the central portion and peripheral portion of the interior of the breathing bag along the inner surface of the breathing bag, and the space or gap between the partition wall and the inner surface of the breathing bag acts as a passage for oxygen-enriched gas discharged from the outlet of a canister of an oxygen-generating agent into the interior of the breathing bag. The oxygen-enriched gas can flow through the passage while kept in good contact with the inner surface of the breathing bag, and thus can be cooled to a temperature suitable for inhalation by the user.
