Title: Process and a device for transferring leachable substances in waste material into gas of leach stable compounds
Inventor: ERIKSSON SVEN
IPC: F23G5/32
Filed: 1990-01-24
Abstract: A b s t r a c t A process  of transferring environmentally harmful sub-stances which are easily leachable from openly deposed waste material, and which to a large proportion consists of inorganic material, such as spent spot linings for aluminium electrolysis cells, into gaseous form or into leach stable compounds, comprises that the material in finely ground form is heated and in that reagents such as silica, water and oxygen are added in a cyclone furnace (1) comprising a heat source (2) for example a plasmagenerator, and a cylindrical furnace vessel (10). By feeding the waste ma-terial and the reagents via a mixing and prereaction chamber (3) which is located between the high temperature source and the vessel (10), a very high proportion of the added materials are reacted in the furnace. A device for carrying the process into effect comprises a cyclone furnace (1) having a high plasma generated (2) tangentially connected to the horisontally arranged cylindrical vessel (1), at one end portion thereof, via a mixing and prereaction chamber (3) into which the waste material and the reagents are injected and super heated before they flow into the furnace vessel (10). At the other end portion of the vessel (10) there is an upper outlet for drawing off formed gaseous material, and a lower outlet (4) for drawing off formed solid and/or liquid material.

Title: Pulse-Spacing Decoding
Inventor: GUTEKUNST JURGEN
IPC: H03K5/153
Filed: 1990-02-16
Abstract: A circult for filtering pulse sequences of a given frequency out of a composite signal includes a series combination of a monostable multivibrator (MF) and a random-access memory (RAM), an address register and a clock. The monostable multivibrator (MF) serves as a pulse shaper of incoming signals.          The input (DE) and output (DA) of the random-access memory (RAM) are connected to the inputs of an AND gate (UG).  An address counter register (AR) associated with the random-access memory (RAM) has a count cycle whose duration is equal to the pulse spacing of the sequence to be recognized.  During each clock period (T2), the current signal state of the input (DE) of the random-access memory (RAM) and the content of the addressed memory cell are checked for equality by the AND gate (UG) and the current signal state is then written into the cell.

Abstract: The invention relates to a method of making in a mould cavity objects having an outer wall from a micro-cellular or non-cellular elastomer (7) and a core consisting at least partly of a synthetic foam (9), wherein, in a first step, a layer (7) of said elastomer is applied by spraying onto the surface (1) defining the mould cavity, wherein, in a second step, before said elastomer is completely cured, a reaction mixture for obtaining a synthetic foam (9) is injected in the thus by the formed elastomer layer (7) defined space (8) of the mould cavity and wherein, in a third step, after the synthetic foam (9) has been cured substantially completely and forms a whole with the elastomer layer (7), the thus obtained object is demoulded.
Patent CA-2013078-A1 (CA)
IPC: H01R24/30
Filed: 1990-03-26
Abstract: A low profile alternating current electrical plug is disclosed in which the electrical pins are terminated in lands at right angles to the axis of the pins. These lands are used for crimping wires to the pins as well as for mechanically stabilizing the pins in the molded plug body. Forming these lands at right angles to the pin axis permits a very thin plug body. The electrical cord exits the plug head at an acute angle to the line of the power pins as well as at an acute angle to the axis of a mating electrical outlet. The wires exit the plug head, however, at a right angle to the pin axes and parallel to the wall thereby maintaining the low profile. At the wire exit, a cone-shaped sleeve acts as a shock absorber for forces exerted on the cord, thereby absorbing most of these forces before they reach the pin area. A removal ring is made integral with the low profile plug, lying parallel to the plug when not in use, but pivoting to a perpendicular position when grasped by a finger. Due to the low profile of the plug and the wall-hugging position of the cord, decorative covers can be installed over both the wire and the plugs, making the entire electrical installation aesthetically appealing.

IPC: G01S15/52
Filed: 1991-05-30
Abstract: The device for the detection of movement consists of a transmitter (1) and receiver (2) of electromagnetic, sound or light waves. A frequency shift demodulator (3) connected to the receiver (2) supplies a signal which varies gradually as a function of the detected movement. An analogue-digital converter (5) transforms the signal into a digital signal. A memory (6) is connected to the converter (5) whose loading can be controlled and continuously transmits data corresponding to the memorised signal in the absence of movement. A comparator (8) continuously compares this memorised signal in the absence of movement with the signal originating from the demodulator (3) and transmits a signal when the first of these is less than the second. <IMAGE>

Abstract: In a sprinkler head comprising a sprinkler body (1) and a sprinkler base (4), the nozzle wall of the sprinkler base (4) is the fixed supporting plate (8) of a rubber-elastic nozzle plate (11) resting on it. The nozzle plate (11) comprises a plurality of elastic nozzle projections (12) formed on it which engage in receiving bore holes (9) of the supporting plate (8). The axial length of the elastic nozzle projections (12) in relation to that of the receiving bore holes (9) is such that their elastically deformable ends always project beyond the outer surface (14) of the supporting plate (8). Furring of the nozzle projections can easily be removed by exerting a slight external force on the elastically deformable ends. Nevertheless, the spray-forming outlet ends of the nuzzle projections (12) are so thick-walled and of such material quality that they withstand ordinary water pressures and therefore have good spray guidance properties.
