Title: Improvements in or relating to liquid-level indicators
IPC: G01F23/16
Filed: 1923-03-14
Abstract: 195,078. Weymann, C. T. March 17, 1922, [Convention date]. Indicators actuated by pressure of head of liquid.-A liquid-level indicator of the kind in which a pressure gauge measures the pressure necessary to force air through a tube immersed in the liquid is provided with a piston or flexible diaphragm device adapted to close the entrance to the immersed tube when the air pressure falls below a certain limit and to place the pressure gauge in communication with the atmosphere. The pipe 3, Fig. 1, dipping into the liquid in a reservoir R is connected to the pump P and the pressure gauge m through a cylinder containing a piston 2, which, when the pressure in the air supply pipe p is below a certain limit, closes the entrance to the pipe 3. When pressure in the airsupply pipe rises, the piston is moved against the compression of a spring 10 so as to allow air to pass through orifices 9, 8 in the piston into the pipe 3, and so as to close the opening 6, which places the pressure gauge in communication with the atmosphere. In a modification, the piston is replaced by a flexible diaphragm 2, Fig. 3, carrying valves 7, 8 controlling the entrance to the pipe 3 and the outlet 6 to the atmosphere. When the pressure of the air from the pump rises above a certain limit, the diaphragm is forced downwards, thus opening the valve 7 and closing the valve 8.

Abstract: 1342999 Copying process and apparatus DIETZGEN CORP 17 Feb 1972 [19 Feb 1971] 7464/72 Heading G2A In a copying process, a master sheet 29 superimposed on a photo-sensitive sheet 28 is fed around the periphery of a rotatable drum 1 and is exposed through a wall of the drum in one peripheral portion, subsequently developed in another peripheral portion and the two sheets finally separated. A hollow transparent drum 1 has O. V lamps 6 and an endless belt 5 wound around rollers 2, 3, 4 for driving the sheets around the drum and past the exposure station. Before passing over driven roller 4, a guide 23, lying in an indentation in the roller deflects the sheets to developing section 10 in which they are exposed to heated ammonia vapour stored in a chamber 11 having an opening closed by a perforated blanket 14 of P.T.F.E. The sheets are deflected along the outside of the perforated sheet stretching between seals 19 and 20 and the ammonia developer diffuses through the perforations to the diazo-type photo-sensitive sheet. The vapour enters chamber 11 through valve 13 and is electrically heated by elements 18 and 21 such that no condensation occurs on the drum. If the photo-sensitive sheet is not porous it is separated from the master, reversed and passed through the machine again without the lamps on, when it will come into contact with the ammonia vapour.

Title: Improvements in or relating to the laundering of textile articles
IPC: D06F35/00
Filed: 1956-03-12
Abstract: 799,788. Washing machines. SULZMANN, E. March 12, 1956 [Feb. 3, 1956], No. 7578/56. Class 138 (2). [Also in Group XXXV] In a method of laundering textile articles in a washing machine, fresh water is supplied for soaking, washing and rinsing, and the temperature during washing is automatically controlled by varying the fresh water supply whilst maintaining a constant supply of heat at a temperature not less than that of boiling water. In Fig. 1 a washing machine comprises a perforated cylindrical drum 11 reversibly rotatable about bearings 12 in an outer casing 10. At the commencement of the washing period a lever 20 is operated to open a valve 18 and admit steam into the washing liquid through a conduit 17. When the washing liquid reaches a predetermined temperature, further rise is prevented by a contact thermometer 23 which thereafter causes intermittent operation of a valve 15 to admit fresh water through a conduit 16. The washing liquid passes out of the machine through an overflow 10a. In one arrangement, starting with some rinsing water in the machine from a previous operation, more water is added by time switch operation of valve 15 during a soaking period. The water is then shut off, the steam turned on and soap added through a funnel 27. When the predetermined temperature is reached it is maintained automatically during the washing period as described above. The steam supply is finally shut off by time switch operation of a release solenoid 25 for lever 20, and water is supplied again for rinsing purposes by time switch operation of valve 15. Several alternative arrangements for introducing soap and water during the soaking period are referred to. Electric, gas or oil heating is also referred to.
