Abstract: A tape recorder calculator is disclosed. The tape recorder comprises a cassette charging portion thereof on one side surface of a polyhedron of a housing and digit keys on an other side surface. The display for displaying counted values is also used as a counter display of the tape recorder and is rotatably provided on one side surface of the polyhedron so as to automatically switch its display function in accordance with rotation of the display.
Abstract: An annular ferromagnetic portion, i.e., "track", of the body to be balanced is rotated adjacent a first electromagnet having a decaying magnetic field which renders that track magnetically homogeneous. Thereafter, a large electrical current of short duration from the discharge of a capacitor is passed through a second, marking electromagnet positioned adjacent that track to produce a high-intensity magnetic pulse. This magnetic pulse produces a very localized spot of permanent magnetization in the track which spot serves as the reference "mark". When the body is then rotated during its balancing operation, that mark will produce an electrical signal each time it passes a magnetic/electric transducer positioned adjacent the rotating track.
Abstract: Method and apparatus for automatically inscribing magnetic marks on a moving wireline are disclosed. An alternating magnetic field is generated for application to a zone on the moving wireline. The marks are inscribed on the wireline by interrupting the field in response to a control signal corresponding to the time for a mark. The interruption is synchronized to alternations of the field and movement of the wireline. The interruption begins between alternations of the field and is maintained for a time sufficient for a predetermined length of the wireline to be moved beyond the application zone. This predetermined length is related to the length of the zone on the wireline affected by the alternating magnetic field, which is applied with a U-shaped electromagnet held in proximity to the wireline. Wireline movement pulses are generated by a tangentially coupled measuring wheel driving an encoder.
Abstract: A read-write head writes data relative to a patient in a magnetic tape disposed on a sample supply container and reads out the written data. The read data are displayed on a display device to check the data for correctness. The sample supply container in which the data have been written is delivered to a pipetting device, which distributes a sample in the sample supply container to a sample receptacle. At this time, the data stored in the magnetic tape of the sample supply container are read out by a magnetic head, and written in a magnetic tape attached to the sample receptacle. The data written in the magnetic tape of the sample receptacle are read out by a magnetic head, and compared with the data stored in the magnetic tape of the sample supply container, and then the sample is pipetted.
Abstract: There is described a method of guiding a machine as it moves relative to a surface, which is preferably the surface of a workpiece on which the machine is working, by selectively magnetizing a layer of magnetic material provided at or close to the surface so as to define a path of movement, producing guidance signals during the relative movement by detecting the selective magnetization, and using the guidance signals to automatically guide the relative movement, so that the defined path is followed. Data other than guidance data may be provided on the layer by selective magnetization.

Abstract: An apparatus for providing information, for example, tourist information, comprising a sound reproducing device which can receive a prerecorded tape, such as a cassette, having informative touring information for a specific location, the apparatus being manually energizable and being shut off at predetermined points by the tape. The tape can have numbers thereon viewable by the operator and for indicating the road exit or location.
Abstract: Means for providing stationary images from slides and sound related to these images include a retainer for insertion of a slide, an endless taut magnetic tape mounted within the retainer, and stationary magnetic heads that impose sound tracks on the tape and reproduce such sound tracks. Control circuitry connected to the heads provide a group of sound tracks for each image of a slide in predetermined sequential order.
Abstract: Magnetically encodable tags in tape format are written sequentially with tire identifying data and applied to the sidewall material of a green tire. The encoded data may be read from the tire at any point in the tire manufacturing process and the signals indicative of the tire identification number converted to an alphanumeric display and/or fed to a process control computer for on-line quality assurance and control or stored as a recorded history of the tire manufacturing process for inventory control.

Abstract: A slide and magnetic tape retainer provides capability of insertion of a mounted transparency and has a spiral spring type tape that is self retractable, after being transported, to its original position. The tape is guided for non-interference with the slide or transparency within the retainer by means of rollers. Mechanical energy is stored in the tape when a portion of it has been transported, and upon release of the transported portion the tape returns to its original position by itself without use of any mechanical aids. Transportation of the tape occurs when a motor is energized by a push button and a cam on the motor in cooperation with a switch times the recording or reproducing period of the tape when such tape is also in cooperation with a magnetic head.
Abstract: This ticket making machine is capable of issuing a single ticket without waste of ticket stock. A web of ticket stock having a magnetic stripe record surface is arranged to be advanced around a rotating carrier having a magnetic recording unit and one ticket (web) parting member arranged internally threof. The web is passed between the rotating carrier and a complementary ticket (web) parting member. The peripheral speed of the rotating carrier is very much greater than the speed of the advancing web, whereby the information is magnetically recorded in close to conventional manner. The one parting member is a double-ended anvil arranged to be rotated into and out of position for parting the web in cooperation with a blade forming the complementary parting member. A camming surface arrangement in the same frame structure as the carrier and web are mounted and a cam follower coupled to the anvil toggles the latter on demand for exerting relatively light force for engaging the two in parting the web.

Abstract: A method and apparatus for providing a signal when equipment being run into or out of a well on a magnetizable wire line reaches a previously visited point in the well below the surface. With the equipment at the point in the well to be revisited, a magnetic mark is applied on the wire line at an appropriate spot at the surface. The magnetic mark may be of one or more dipoles and in the case of three or more dipoles they are arranged in close proximity along the length of the wire line with alternately opposite polarities and on a common axis of polarity, with said axis substantially paralleling the length of the wire line. Subsequently, in running the equipment in or out, at least one of the magnetic dipoles is detected at the same appropriate spot at the surface and is used to actuate a signaling device.
Abstract: A system is disclosed for controlling the discharge of articles from a steel belt conveyor. When articles are placed on the belt at the loading station, the belt is magnetized at a high intensity in a very small area which has a predetermined relationship, longitudinally of the belt, to the position of the article on the belt. The magnetized spot is also positioned transversely of the belt in accordance with the station where the article is to be discharged. At each discharge station there is an arrangement in the form of a plow and means to move the plow to and from the path of articles carried on the belt so as to deflect the articles from the belt. The plow operating mechanism has an electronic control which includes a Hall-effect transducer positioned adjacent the bottom surface of the belt and relatively positioned transversely of the belt along the path of the magnetized spots for that station.
