Title: Liquefied gas transporting tank lorry
Inventor: HASEGAWA IWAO
IPC: F17C13/00
Filed: 1982-11-18
Abstract: PURPOSE:To prevent residual liquid from being generated in a bulk lorry tank, and avoid danger, by connecting a lower portion of the tank through an outlet pipe to an evaporator, and also connecting the evaporator through a pressure steam pipe to an upper portion of the tank. CONSTITUTION:A heat exchanger 29 serves to conduct a heat exchanging operation between exhaust gas from a prime mover for propelling a tank lorry and warm water, and to heat the warm water. The heat exchanger 29 is connected to an evaporator 22, and the evaporator 22 is connected through an outlet pipe 28 and a pressure steam pipe 34 to a lower portion and an upper portion of a bulk lorry tank 1, respectively. A part of liquid taken out of the bulk lorry tank 1 is vaporized by the evaporator 22, and is in turn fed to the upper portion of the tank 1 to be pressurized. Then, liquefied gas as is obtained is emitted from the tank 1. Thus, there is no creation of residual liquid in the tank 1, and as it is not required to provide a liquid feed pump, etc., there is no danger of explosion.

IPC: A61C7/20
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To provide an article treating method capable of applying treatment on the required surface of article held fixedly without much attention or labor of a worker. SOLUTION: A dental correction band is arranged in an article receiving recess 36 of a holder 34 made of elastic material. While the holder 34 is rotated around the axis sand blasting work is applied to the inner surface of the band.

Title: Work feeder
Inventor: TANAKA NOBUAKI
IPC: B65G27/34
Filed: 1982-11-25
Abstract: PURPOSE:To prevent a conveyed work from any damage, by rotating a conical work dispersion table intermittently, while constituting it so as to feed the work via a trough set up in a radial direction and being reciprocatively vibrated, in case of a work feeder for an automatic quantitative machine. CONSTITUTION:Conveyed works W dropping on a dispersion table 1 rotating intermittently from a supply device 4 are released from their contact friction in time of stopping the intermittent rotation, causing a conic surface to go down, and are guide into a trough 2 being set up radially beneath the dispersion table 1 by guide plates 2a and 2b, thus portioned out. Since the trough 2 is given a reciprocative vibration in a radial direction by a vibration generator 7, these conveyed works W are transferred toward a receiver box 3 past on the trough 2 and housed inside the receiver box 3. When these supplying works W inside the receiver box 3 reach a fixed quantity, detector elements 12 and 13 give forth a signal, stopping the vibration generator 7 and the transfer motion, whereby a gate 8 is opened and these elements 12 and 13 are taken out. Thus, these works can be fed without suffering any damage.
