A centrifuge for separating sludge from liquids comprises a hollow rotor body consisting of two parts 10, 20 normally making a fluid-tight engagement with each other through a seal 12 but adapted to be moved relative to each other to allow for discharge of sludge accumulated during centrifugation. The rotor part 10 is fixed to one end of a hollow shaft 13 supported in bearings 14 and driven by a belt-drive 13<SP>1</SP>. A shaft 15 coaxial with, and movable axially with respect to, the shaft 13 is drivingly connected thereto by a spline, a pin or, as shown, a key 16 on the shaft 13 engaging in a keyway 17 on the shaft 15. The latter has attached at an outer end thereof a boss 18 carrying radial vanes 19 attached to or integral with the rotor part 20. The liquid to be clarified is fed through a pipe 24. The clarified liquid discharges through a central aperture 21 into a compartment 28 of a stationary casing 26 which has another compartment 29 for receiving discharged sludge. The shaft 15 is axially loaded by a spring or by hydraulic or pneumatic means in order to force the rotor part 20 against the seal 12 during operation. Sludge will accumulate in the rotor until it produces sufficient pressure to overcome the force of the spring or of the hydraulic or pneumatic means acting on the shaft 15 at which point the rotor part 20 will move away from the part 10 to allow sludge to discharge in compartment 29. Alternatively, electrically, hydraulically, pneumatically or manually operated devices may be employed to cause axial displacement of the shaft 15, and hence discharge of the sludge, periodically at preselected intervals or as and when required. The hydraulically and pneumatically operated devices may be reversible so that they can be used both to load the shaft and effect discharge of the sludge.

Abstract: 1412543 Orthodontic apparatus M E NORTHCUTT 2 Aug 1973 [1 Nov 1972 15 June 1973] 36756/73 Heading A5R A removable orthodontic appliance, which exerts corrective forces on teeth, includes means for sensing and for recording the amount of time the appliance is in use. Sensing means for actuating the recorder may be responsive to body heat, to capacitance, resistance or other attributes of skin electrolytic functions or to fluids in the mouth, or to a combination of two properties. The recorder may be electronic, or a charging or discharging electric cell, or a small clock. Electrical power, when required, provided by a small battery, the electrolytic activity of the mouth, or spring energy of a headgear. As shown in Fig. 1, headgear comprising an outer bow 14, with coil spring 26, and an inner bow 12, is held in position by an elastic band 20 with a pad 24 which contacts the back of the patient's head, the band 20 being fastened to the hooked ends of outer bow 14 by connectors 22. The inner bow 12 is connected to molars 17 by brackets 16, adjustably mounted on the ends of inner bow 12, whereby the tension of band 20 is transmitted to the patient's teeth. In order to record the time during which the appliance is in use, a clock is actuated by a switch connected to the band. Alternatively, the clock may comprise an integrated circuit which consists of an oscillator, a divider, and a buffer giving an output of lapsed time in code form. The integrated circuit may be controlled by a quartz crystal, supplied by a miniature battery and connected to a "reset" switch. A micro-switch, operated by tension, and possibly also by temperature or pressure, actuates the oscillator as long as the headgear is in use. The total time lapse may be decoded and displayed in digital form. Alternatively, there may be a detachable connection to decoder and display apparatus at a fixed point, e.g. in the orthodontists' office. To discourage tampering, the sensing means may be responsive to tension within a given range of values only.
