Patent GB-125954-A (GB)
Title: Automatic Stopping Device for Pneumatic Hammer-drills and other Pneumatic Tools.
IPC: B25D9/16
Filed: 1919-04-09
Abstract: 125,954. Soc. Belge d'Outillage Pneumatique (Ateliers Rorive). April 17, 1918, [Convention date]. Percussive hand tools. -In a pneumatic hammer or like tool in which, when normal resistance to the tool is not encountered, the compressed air automatically effects a stoppage of the tool, waste of compressed air is prevented by employing an automatic stopping device which closes the exhaust passage from the rear cylinder end, thereby reducing the rearward stroke of the piston and preventing the latter uncovering the exhaust port from the front cylinder end. The piston remains stationary between two bodies of compressed air. In the tool, with the parts in the position shown in Fig. 1, compressed air passes through ports a to move the piston rearward, exhaust passing through ports b, c; during the stroke, the piston opens forward exhaust ports f, closes the exhaust ports b, c, and cushions air to move the valve d into the position shown in Fig. 2, when air passes through ports e to move the piston forward. When through lack of resistance, the tool D moves forward to uncover a port g, compressed air is admitted to move a cylindrical hody i to close the exhaust ports b, c; when the tool D closes the port g, fluid from this port exhausts through a small aperture l and fluid from the cylinder passes through ports k to return the body.

Title: Improvements in or relating to machines for the chemical cleaning of textile articles
IPC: D06F23/02
Filed: 1958-03-25
Abstract: 857,445. Drying apparatus. BOEHLER, M., and WEBER, F., [trading as BOEHLER & WEBER KOMM.-GES.]. March 25, 1958 [April 8, 1957], No. 9449/58. Class 34(2) A dry cleaning apparatus comprises a wash drum 1 rotating on a shaft 2 within a housing 3. After the washing cycle is complete and excess solvent has been evacuated, drying air is forced into the drum 1 through pipe 5 and perforations 1<SP>1</SP> in the periphery of the drum. From pipe 5 there is branched a pipe 6 which is of equal cross-section to pipe 5 at the point of branching, but which tapers considerably, thereby increasing the speed of flow of the air issuing through bore 10. Annular member 11 mounted on the drum is provided with annular ridge 13 which extends somewhat into the drum to assist the tumbling of the articles, and also slots 12 through which the air issuing from pipe 6 passes; the stream of air strikes coniform surface 8<SP>1</SP> of door 8, which encloses window 9, and is axially deflected thereby into drum 1 through opening 1<SP>11</SP>. This axial blast of air aids the drying of the articles by causing them to be turned over as well as tumbled, and minimizes damage caused by the accumulation of the articles in the region of the door. The cross-section of exit pipe 15 is wider than that of pipes 5 and 6 together, so that a slight vacuum is created in the drum which assists drying. If preferred, pipes 5 and 6 may be supplied with air impelled by separate blowers.

Title: Improvements in or relating to apparatus for artificial respiration
IPC: A61M16/00
Filed: 1954-03-31
Abstract: 783,180. Respiratory appliances. DRAGER, O. H. March 31, 1954 [April 4, 19531, No. 9503/54. Class 81 (2). Artificial respiration apparatus for use during anµsthesia, comprises a closed respiration air system including a respiration bag enclosed in a sealed chamber in which positive and negative pressures are alternately produced. The respiration bag 10 is connected in a closed respiration circuit by a connecting pipe 6 which branches into tubes 3 and 7, one 3 of which contains an exhalation non-return valve 4 and a carbon dioxide absorption cannister 5 and the other 7 being provided with an inhalation non-return valve 8 and connected with a pipe 9 through which anµsthetic is supplied to the apparatus. The tubes 3 and 7 are connected with a tube 2 which communicates with the patient by an intratracheal catheter. An additional respiration bag 31 is connected to the connecting pipe 6 by way of a valve 30 and is provided for the withdrawal of excess anµsthetic gas or the supply of additional anµsthetic gas as required. The respiration bag 10 is contained in a chamber 11 connected with a pump 15 which causes the air pressure within the chamber 11 to alternately rise and fall so that the resultant collapse and expansion of the respiration bag 10 brings about artificial respiration. Air is withdrawn from a pump chamber 20 connected with the chamber 11 by an injector 16 through a valve 18, 21 on the suction side of the injector 16, an adjustable excess pressure valve 27 on the pressure side of the injector 16 being open and an adjustable suction valve 29 on the suction side of the injector 16 being closed. When the pressure in the pump chamber 20 has reached a preset minimum, a diaphragm 26 in the wall of the pump chamber 20 moves inwardly to close the valve 18, 21 and open another valve 19, 22 which is on the pressure side of the injector 16 and connected to the first valve 18, 21 by a lever 23. Air passes into the chamber 20, the excess pressure valve 27 closes and the suction valve 29 opens. When the pressure in the pump chamber 20 has reached a preset maximum, the diaphragm 26 moves outwardly so that the valves are reversed and air is again withdrawn. The maximum volume of the respiration bag 10 is adjustable by arranging either a displaceable piston 12 or an inflatable bag (not shown) in the chamber 11 so that it limits the expansion of the respiration bag 10. Alternatively the respiration bag 10 may be exchanged with others of different volumes. The diaphragm 26, the suction valve 29 and the excess pressure valve 27 may be adjusted to respond at different pressures so that the maximum and minimum pressures in the chamber 11 and the time of rise and fall of pressure may be adjusted. Specifications 625,284 and 649,229 are referred to.
