Title: Servo control mechanism for a curtain
IPC: A47H5/02
Filed: 1979-11-15
Abstract: A servo control mechanism for controlling the reciprocal movement of a piston member along the length of a curtain rod. The curtain rod is composed of a fluid pressure-tight tubular member made of a nonmagnetic material and having pressurized fluid supply ports therein adapted to supply pressure to opposite sides of the reciprocal piston member. A plurality of ring members, certain ones of which are made of magnetizable material, surround the curtain rod and are capable of movement along the length of the rod. A plurality of permanent magnets are reciprocally mounted inside the curtain rod and are magnetically coupled to certain ones of the curtain rings which are made of a magnetizable material. An elongated strand extends between the piston member and at least one of the permanent magnet members inside of the curtain rod so that a driven movement of the piston member will cause a forced movement of the permanent magnet therewith. The magnetic coupling between the permanent magnet and the curtain ring will cause a movement of the curtain ring with the piston member.

Title: Apparatus for optically reading a disc-shaped record carrier, in particular for rapidly locating a desired program section
IPC: G11B7/09
Filed: 1979-12-11
Abstract: An optical read apparatus for a disc-shaped record carrier. The read apparatus comprises an optical read unit which includes a deflection element for controlling the radial position of the scanning spot, for which purpose said deflection element is included in a closed servo control loop. In order to enable a desired program section on the record carrier to be located rapidly, the read unit can be moved in the radial direction. During this movement of the read unit the servo control loop is rendered inoperative each time after the deflection element has reached a preset maximum deflection, after which this deflection element is reset rapidly and the servo control loop is rendered operative again. Thus it is achieved that image reproduction is also maintained during the rapid search for a desired program section.

Title: Apparatus and method for a telephone alarm system.
IPC: H04M1/21
Filed: 1981-10-23
Abstract: An automatic telephone message device for transmitting recorded messages to predetermined telephone numbers. The device is connected to the telephone jack and AC power source of the user's telephone, and is also connected to a standard tape recording system. One or more messages are recorded by the user on the tape recorder. The microprocessor controlled circuitry of this device provides memory space for convenient storage and modification of several telephone numbers. This device is responsive to manual, timed automatic or remotely generated activation signals for transmitting the recorded message to parties answering at the specified telephone numbers. An additional audible alarm may be set to sound at predetermined times, and if a manual switch is not closed within a specified time thereafter, the device calls the selected telephone numbers and transmits the recorded message. In response to remote transmitter activation or lack of response to the audible alarm, a tone is transmitted in addition to the message indicating that the user is probably in the vicinity of the device. All specified numbers are redialed until the device senses that they have been answered, or until a specified maximum number of dialing attempts have been made. The recorded message may be reviewed and the alarm activation time may be modified or deactivated by a party accessing the device from a remote telephone.

Title: Absorbent flat product, and process for its manufacture.
IPC: D21F11/00
Filed: 1982-10-13
Abstract: The present invention provides for an absorbent planar structure or so-called "sponge cloth" as well as for the method of making such a structure.
