  • Patent number: 5900575
    Abstract: The invention relates to a bottom plate member (6) which is designed and made for initially tightening a chamber in which a high gas pressure is generated, for example the propellant charge chamber (4) in an ammuniton round for a recoilless weapon system or in pipes or containers within the process industry. The plate member (6) is breakable and opens for the gases to exit when the gas pressure within the chamber exceeds a certain level. The plate member has a through hole (12) in the center which gives an effective starting point for the cracking process as well as fractural impressions (10) to control the cracking process so that the plate is divided into a number of well defined parts of flaps (11) which are connected to each other. The plate member (6) further comprises a number of straight edges (16), which number corresponds to the number of flaps (11), against which edges the base of the flaps are arranged to be folded when the plate member opens due to the gas pressure.

  • Patent number: 5820369
    Abstract: A subperiosteal bone anchor used in two distinct applications; as an orthodontic anchor system, and as an orthopedic anchor system. As an orthodontic anchor system, it is used for treatment of growth disharmony and malalignment of the teeth in which the subperiosteal bone anchor is surgically placed in the subperiosteal tunnel on skeletal bone allowing osseointegration between the subperiosteal bone anchor bone interface and the bone. After osseointegration a palatal bar or palatal wire is attached to the cylinder of orthodontic anchor system, which is attached to the abutment, which is attached to the subperiosteal bone anchor, and the palatal bar or palatal wire is also attached to bands around one or more teeth, holding them immobile. As an orthopedic anchor system the subperiosteal bone anchor is used to stabilize devices which need to be anchored to a bone, or to transmit attractive or distractive forces to a bone for reconstruction or transformation.

  • Patent number: 4467458
    Abstract: A small size sequence controller for a read-only memory in which data stored in a read-only memory (4) are read out sequentially to operate an output relay during a time interval in accordance with the stored data, and the relay controls a load. Clock pulses generated by a frequency-dividing clock pulse generator (36) are applied to presettable down counters (38), (39) in which the clock pulses are divided down to pulses each having the time period corresponding to the preset value. The divided pulses are applied to a binary counter (34). Predetermined data are stored in the read-only memory (4) in advance. When addresses are allocated by the binary counter (34), data outputs (D1)-(D8) deliver "1" or "0" data in parallel. The data outputs are applied to an output relay which is rendered "ON" or "OFF" in accordance with the data "1" or "0".

  • Patent number: 4456967
    Abstract: A write-only sequence controller in which data regarding the period of time in one cycle is divided into data "1" and data "0" which are designated by the number of the clock pulse. To this end, the system is provided with ten key switches for converting the data "1" and data "0" into the number of the clock pulse and an encoder for converting the number of the clock pulse into BCD codes. The BCD codes are set in presettable counter which counts the clock pulse from a clock pulse generating circuit through gate circuits. The system is further provided with a binary counter for counting the clock pulse applied to the presettable counter, memory RAMs connected to address lines of the binary counter for memorizing data from the counter, and an EPROM for memorizing data stored in the memory RAMs. When the number of the clock pulse applied to the presettable counter and to the binary counter reaches the preset number, the gate circuits are closed.
