Title: Method of administering securing and detaching a rinsing container
IPC: B67C3/00
Filed: 1974-02-19
Abstract: 1458052 Rotary back-pressure filling machine; washing filling heads HOLSTEIN & KAPPERT AG 19 Feb 1974 [20 Feb 1973] 7596/74 Heading B8T To wash the filling elements of a rotary backpressure filling machine, a rinsing container is raised by a contact pressing device 36 of the machine so that a sealing member 26 presses against a centring bell 27, and the container is pressurized whereby a sliding sleeve 20 of the container is moved axially downwards and clamping means 19 is actuated to retain the container on the gas tube 17 of the filling element. The washing process continues by increasing the pressure to that of the filling machine tank when the liquid valve 8 is opened to allow liquid to flow through the filling element and up passage 10 thus initiating the rinsing operation. The machine is rotating and when a container reaches the machine exit, device 36 is lowered thereby causing closing of valve 8, rinsing now being limited to spaces below the valve. On continued rotation, the device 36 is raised again to repeat the rinsing operation. When the washing is complete, air valve 39 is closed to reduce the container pressure, thereby releasing clamping means 19 and hence the container. The container comprises parts 14, 23 and a sliding sleeve 20, the body 29 in the inside part 14 being supported in the device 36. The sliding sleeve 20 moves on the inside part against a spring 21 and the external part 23 moves on the sliding sleeve by the action of a spring 24. Clamping means 19, preferably spheres, move radially in the apertures 18 in the inside part such that recesses 34 in the sliding sleeve are adjacent the spheres until an internal pressure in the container compresses spring 21, thereby moving sliding sleeve 20 downwardly which forces the spheres to abut against the gas tube 17, thus securing the container to the filling machine. When, with the pressure maintained in the container, the device 36 is moved from underneath the container, the spring 24 forces sliding sleeve 20, inside part 14 and gas tube 17 to move downwardly with respect to external part 23, thereby closing the valve 8. In an alternative embodiment, the sliding sleeve is modified to accommodate non-vertical gas tubes.

Title: Means for locating earth faults or the like in electrical cables or conductors
IPC: G01R31/08
Filed: 1945-03-27
Abstract: 591,725. Detecting, indicating and locating faults. COGHLAN, A. J. March 27, 1945, No. 7722. Convention date, April 19, 1944. [Class 37] An apparatus for locating earth or shortcircuit faults comprises a source of audiofrequency current applied along, about, or adjacent to a conductor, and a pick-up detector to which is connected an indicator capable of giving a continuously distinctive signal until the fault has been located, whereupon the signal rapidly fades. Audio-frequency currents, from a vibrator coil 32 which is connected in series with its contacts 34, a fuse 26 and a switch 19 across an external source of current 36, are applied through a condenser 35 and a lamp 27 to the part of the cable 38 under test which is between the end connected to the lamp 27 and an earth fault 39. When a pick-up detector 13, comprising a coil secured to a pair of tongs made of an admixture of iron and silicon and connected to earphones 12, is applied along, about, or adjacent to the cable 38 and moved from the end connected to the lamp towards the other end a continuous distinctive signal will be audible in the earphones 12 until the detector reaches the earth fault 39, whereupon the signal fades rapidly and thereafter ceases. The condenser 35 functions as a " spill " circuit and need only be used if desired. The dector coil may be replaced by a plurality of coils. The lamp 27 will generally illuminate unsteadily until the fault has been located, but the audible signal is primarily relied upon. If an external supply is not available a reserve battery 11 is used.

Abstract: 408,094. Shaping helical surfaces. SCHIESS-DEFRIES AKT-GES., 114, K÷lner Strasse, D³sseldorf, Germany. March 14, 1933, No. 7774. Convention date, March 15, 1932. [Class 83 (iii).] In machining the rear surfaces of propeller blades on ordinary boring mills or centre lathes, the work being oscillated during machining and the tool being given a movement which produces a helical surface, additional means are provided to give the tool a controlled movement along a guide track to generate the required shape of the back of the blades. The tool is also given a rocking movement to maintain the cutting angle throughout the range of movement. When the additional movement is imparted to the tool in a direction perpendicular to the propeller axis, the usual rotary support on the transverse bar 1, Fig. 2 of a boring mill is replaced by a support 2 carrying a vertically movable saddle 3 on which the rocking tool-holder 6 is movable along guides 4 perpendicular to the work axis. In an alternative form, the vertically movable slide 9, Fig. 4, is transversely movable on a horizontal guide 4 adjustably mounted on the transverse bar 1 and carries the rocking tool holder 6. In another form, in which the work oscillates about a horizontal axis, the rocking tool holder is given the additional movement along a vertical slide on a saddle movable parallel to the work axis on a carriage guided transversely along the bed of the machine. When the additional movement is imparted to the tool in a direction normal to the curved back of a blade, i.e., always along a radius of curvature, the tool holder 6, Fig. 7, is slidable along a guide 4 on a saddle 3 which is pivoted at 11 to the vertically movable carriage 2, the movement along the guide 4 being always normal to the curved back X of the blade. The normal generating motion of the tool, the additional movement either perpendicular -to the work axis or along a radius of curvature of the blade surface, and also the rocking movement of the tool may be produced by a guide roller shaped according to the changing cross section of the blade, the connection between the roller and tool being preferably effected by means of a hydraulic servo-motor control of known construction, for maintaining the roller free from the pressure of the tool.
