Title: Rotary packer for filling sacks
IPC: B65B39/14
Filed: 1974-07-18
Abstract: 1455348 Rotary packer F L SMIDTH & CO AS 10 April 1975 [18 July 1974] 31953/74 Heading B8C In a rotary packer for filling sacks which have a mouth with or forming part of a valve and which comprises a series of filling spouts 1 rotating about a vertical axis and a sack magazine 4, the mouth of each sack 3 is automatically opened prior to complete removal of the sack from the magazine, and the sack is removed from the magazine by a filling spout entering the mouth, the spout being oriented with its mouth directed forwardly in the vicinity of the magazine. In Figs. 1, 2, the spouts are fixed substantially tangential to a rotating container drum 5. Each sack in turn is partly removed from the magazine by a suction gripper 4<SP>1</SP> mounted on a fluid ram 9 such that the sack mouth is opened to receive a filling spout. Operation of the ram 9 and suction gripper 4<SP>1</SP> are synchronized to the drum movement by means of an electronic sensor 12. In a modification (Fig. 3, 4, not shown), each spout is rotatable about a vertical axis, and a cam causes the spout to move from its normal radial position to a substantially tangential position as the magazine is approached. In Fig. 6, the mouth of each sack is opened by a jet of compressed air from device 27, a spring biased roller device 30 preventing inflation of the bag. The spout is angled so that it frees the bag bottom from retainer 29 and then the bag top from retainer 28. The bags are advanced upwardly by fluid device 31 under control of a sensor 33. If a bag mouth fails to open, roller device 30 is contacted by spout 1 and when it abuts sensor 36 an electrical circuit is completed, and a suction gripper 35 operates to remove the sack from the magazine.

Abstract: 648,191. Anaesthetic apparatus. TALLEY, H. A. E. Dec. 13, 1948, Nos. 32162/48 and 4612/49. [Class 81(ii)] In anaesthetic apparatus a temperature sensitive means controls the flow of air through a liquid anaesthetic chamber and further air is then admitted and the mixture is led to a face-piece. In the form of the apparatus described, air enters the anaesthetic chamber 2 through an aperture 7 and non-return valve 8, and leaves through a valve 12 and further non-return valve 22. The valve 12 is connected to a temperature sensitive bellows 13. filled with a volatile liquid, such as methyl bromide, and is tapered so as to pass a controlled amount of air through the chamber 2. An- µsthetic is introduced through a filler orifice 3 and the chamber is provided with pins 28 to prevent excessive cooling during evaporation. A controllable amount of additional air can be admitted immediately above the valve 12 through orifices in the tube 17 and a surrounding sleeve 19, the latter being adjustable by a projecting handle 21. Still further air is admitted through an annular orifice 23, surrounding the tube 17, each time the valve plate 22 is lifted. The aperture 7 is made to extend completely around the casing 6 so that it cannot be closed by the patient's hand and the tube 9 extends sufficiently far into the chamber 2 to prevent loss of liquid if the appliance is inadvertently inverted. A wick 2* may be provided to assist evaporation of the anaesthetic.
