Title: Apparatus and method for separating entrained particulate matter from a conveying fluid
Inventor: NIEDERER KURT WILLY
IPC: B01D46/26
Filed: 1980-09-10
Granted: 1985-03-28
Abstract: An apparatus and method for separating entrained particulate matter from a fluid wherein particulate matter is collected in an overlying porous layer on an upstream side of a rotatable, fluid-permeable filter in a first chamber, and rotatably conveyed into a second chamber and used as an additional filtering medium. The filter comprises a cylindrical drum having a filter surface thereon and is rotatably mounted in an enclosed housing having a fluid inlet and a fluid outlet. Fluid pumping means operatively communicate with the housing for inducing a flow of fluid into the housing through the inlet and out of the housing through the outlet. Chamber means are disposed within the housing and sealingly cooperate therewith and with the cylindrical drum and define a first chamber fluidly communicating with the inlet and a predetermined portion of the cylindrical drum on the upstream and downstream sides thereof. A second chamber is provided which fluidly communicates with the outlet and a second predetermined portion of the cylindrical drum on the upstream and downstream sides thereof. Drive means rotate the cylindrical drum at a predetermined rate through the first chamber for collecting on the filter surface an overlying porous layer of particulate matter, and through the second chamber for filtering fluid through the filter surface and the overlying porous layer of particulate matter. Doffing means are provided for cleaning the filter surface by removing the porous layer of particulate matter therefrom subsequent to the passage thereof through the second chamber.

Patent DE-3164508-D1 (DE)
Title: Coextrusion blowmolding method of producing hollow plastic bodies
Inventor: LEHNARD JAKOB
IPC: B29C49/00
Filed: 1981-03-06
Granted: 1984-08-09
Abstract: The conventional process of manufacturing hollow bodies with multi-layer walls using extrusion and blow molding techniques is improved by first making a preform of a thermoplastic carrier layer with an adhesive layer on one or both sides and then applying the additional layer or layers to the adhesive layer(s) in a separate operation. The additional layer(s) has properties different from the carrier layer and serves as an insulation or barrier layer to shield the carrier layer from substances to be contained by or which will surround the hollow body. Among other advantages, the improved process allows recycling of waste and surplus preform material, stronger heat-seal seams in the hollow bodies, less complicated extrusion equipment and more economic use of expensive barrier layer materials.

Title: Apparatus for identifying discontinuities in time code addresses identifying recorded information signals
Inventor: MENEZES WILLIAM A
IPC: H04N5/782
Filed: 1981-04-07
Granted: 1984-09-13
Abstract: An apparatus and a method are provided for detecting discontinuities in a sequence of time code addresses recorded on a tape, such as a video tape, which also has control pulses recorded serially along its length to synchronize the motion of the tape relative to transducer heads which read and write information signals on the tape. The apparatus and method of this invention read the current time code address from the tape, count the control pulses read as the tape moves, establish a known relationship between the current time code address and the count of control pulses, so that the count represents a counted tape address, and compare the current time code address with the counted tape address for producing a non-compare signal in the event of a difference between these two compared values. A time code discontinuity signal is generated when a predetermined number of successive comparisons result in non-compare signals, indicating that the time code addresses read from the tape have not varied sequentially in a uniform relation to the control pulses. The value of the current time code address and the counted tape address at the time a discontinuity is detected can be used to define both the location and the magnitude of the discontinuity or to enable accurate calculation of the distance between two time code addresses each located on an opposite side of such a discontinuity.

Granted: 1989-01-05
Abstract: The movement between the hinge carriage segment (14) and a door segment (16) is defined by a four-bar linkage (56,58). A handle (34) actuates linkages which extend between these two segments to power the relative movement.

Granted: 1991-06-13
Abstract: A control device for a stepping motor provided with a coil and a rotor performing a rotary movement when a current passes through the coil, comprising means for producing a plurality of time base signals, means for producing pulses for controlling the motor in response to said time base signals, means responsive to the control pulses for supplying the motor while maintaining the current in the coil at a substantially constant and given value. The device also comprises means for analyzing the voltage signal present on the coil or a signal which is representative thereof, and for supplying data concerning the voltage induced in the coil by the rotor movement. The motor supply means may include switching means for connecting the coil to a supply voltage source and for short-circuiting the coil, and means for periodically comparing the coil current to a reference value, during each control pulse, and supplying a control signal for controlling the switching means to short-circuit the coil when a comparison indicates the current exceeds the reference value, and to apply voltage to the coil in the opposite case, until the following comparison operation. This maintains the mean value of the current at a reference value during the control pulses to provide a high-efficiency power supply system. At the coil terminals logic information is derived concerning the induced voltage which can be easily analyzed and used by logic circuits.
