Title: Improved fluid/particle separator apparatus
Inventor: MELLOR FRED
IPC: B01D45/14
Filed: 1981-11-30
Granted: 1987-05-07
Abstract: A fluid/particle separator comprises an apertured rotor (17) substantially closing a circular chamber inlet to which a particle-containing fluid is fed in use. The rotor apertures (19) are bounded by surfaces (22), within the thickness of a rotor disc or on vanes (20) projecting towards the interior of the chamber, which surfaces are inclined to the axis of the rotor, face upstream of the fluid flow and face in the circumferential direction of motion of the rotor such that, in use, particles in the flow rebound from the rotor surfaces and cleansed fluid passes through the apertures and is centrifuged by the inclined surfaces. Baffles including a coaxial plate (13) and radial vanes (14) within the chamber guide the major fluid flow to an axial fluid outlet (5), while a small proportion of the flow is forced through a peripheral clearance (18) between the rotor and the housing (7) to prevent a flow of particle-containing fluid in the opposite direction. The separator apparatus may be mounted across an inlet to a motor, pump or impeller to prevent dust in the air from entering it, and particularly across the inlet to an impeller in a vacuum cleaner.

Title: Speech processing system
Inventor: KANEDA HIROYUKI C O NIPPON ELE
IPC: G10L21/034
Filed: 1982-03-04
Granted: 1987-07-23
Abstract: A speech processor having microprocessor control of the amplitude level of input speech signals. Input speech signals are applied to a digitally controlled level regulator, the output of which is converted into a digital speech signal for further speech processing. The peak level of the digital speech signals over a frame period is compared in the microprocessor with a preset optimum range. If the peak level falls outside the optimum range, control signals for the level regulator are adjusted in a direction to change the amplification/attenuation amount of the level regulator to bring the peak level within the optimum range.

Title: Meter testing device and method
Inventor: PHILLIPS CHARLES EDWARD
IPC: G01R35/04
Filed: 1983-02-24
Granted: 1986-11-06
Abstract: An apparatus and method for verifying the accuracy of watt-hour meters (10) at their operational site includes applying a phantom load (46) to the meter and to a watt transducer (49). The relative watt hour readings of the meter are compared to the watt hours computed from the power to the watt transducer (49) and represented as a percentage error of the meter (10). The phantom load (46) is constituted by a loading transformer with optional load adjustments to take into account different loads to the meter (10) and there are also adjustment means to take into consideration different meter characteristics. The meter watt hour reading is determined from an articulated light generating (27) and receiving means (29) mounted in alignment with the revolving disc (30) so that light passes through the aperture in the disc to the receiving means and then signals the verifying apparatus to give an indication of the watt hour reading of the meter (10). Alternatively the reading is obtained manually.

Date Nov. 21, 1985.The invention relates to a process for measuring the characteristics of test articles made from plastic, particularly polyethylene or polypropylene, to establish whether they are made from non-regenerated, regenerated or optionally a similar plastic which has been regenerated to a certain extent by the infrared spectrometric measurement of the transmission-absorption in the carbonyl group band range of the plastic. According to the invention, the transmission-absorption is measured in the carbonyl group band range at least two different thicknesses of the same plastic and the thickness dependence of these measurements is used as a measurement criterion. The invention is more particularly used on bottle crates or other large injection moulded articles and can be used for classification preferably with sorting according to ageing criteria, also in the case of test articles made from regenerated material, as well as for the selection of old crates suitable for producing regenerated material. The invention also relates to infrared spectrometric means suitable for performing this process.

Title: Writing instrument
Inventor: MANUSCH CHRISTOPH
IPC: G09F23/00
Filed: 1986-09-22
Granted: 1989-02-09
Abstract: The cap for the writing instrument comprises a jacket mounted slidably on a sealing insert or sleeve which provides a sealed moisture chamber for the writing tip when the cap is on the writing instrument. Near the writing tip there is a circular bulge on the shaft of the writing instrument which enters into a sealing engagement with an interior passage of the sealing insert. On putting the cap on the writing instrument the sealing insert is pushed over the circular bulge until it contacts a contacting stop on the jacket. Then the circular bulge presses tightly into the sealing insert and it locks the jacket to the writing instrument so that the entire arrangement is kept in that position until the cap is removed. A signal slider is attached with the sealing insert which is extendable out from the end of the jacket in order to signal in its extended position the proper seating of the cap on the writing instrument. Erroneous indications of a sealed state are prevented with our invention.
