Inventor: HEUSSER MARTIN DIPL-ING ETH
IPC: F15B11/028

Abstract: In a control device (S) for a hydraulic motor (V) which is adapted to be acted upon at both sides, there are provided  working conduits (4, 5) which are alternately connectable via a directional control valve (C) to a pressure source (P) and a tank (T), a load holding valve (H) which is hydraulically openable in a controlled way and is arranged in at least one working conduit (4), as well as a control pressure conduit (13) which is connected to the opening side (16) of said load holding valve (H), with pressure variations arising during the controlled opening of the load holding valve, and the amplitudes of the pressure variations being adapted to be dampened in the control pressure conduit (13) at least via a damping throttle (D). To dampen and eliminate the undesired effect of changes in the viscosity of the pressure medium and/or of a damping throttle which is too tightly set, the damping throttle (D) can be bypassed in both directions by a respective check valve (R1, R2, R1', R2,), a great biasing force which biases the one check valve being adjusted to a value which lies between the pressure values of the pressure extremes that act on said check valve and pertain to at least the first amplitude and the next amplitude of the pressure variations.

Abstract: The invention relates to a process for detoxifying cyanide- and/or cyanocomplex-containing aqueous solutions in the presence of heavy metals from the series consisting of Mn, Co, Ni, Cu, Cd, Zn, in particular Cu, by oxidative treatment of the solutions with a peroxide compound at pHs of 8 to 12, the peroxide compound used being an alkali metal percarbonate. The alkali metal percarbonate, preferably 2 Na2CO3 . 3 H2O2, is preferably added in solid form to the solutions to be detoxified. The process according to the invention, with respect to the use of peroxide compound, is significantly more effective than the previously known process using hydrogen peroxide.

Abstract: An extendable, including screed extensions (20) which extend, retract and pivot relative to the main screed (10). The screed extensions (20) are mounted to the main screed (10) with a zero clearance pivot joint (38). The disclosed pivot joint (38) permits the screed extension (20) to extend, retract and pivot relative to the main screed (10) while maintaining zero clearance at the pivot. The pivot joint (38) includes respective mounting plates (21,28) on the extension screed (20) and the main screed (10) which are adapted for substantial coextensive engagement with each other in a plane perpendicular to the longitudinal axis of the paver (5). A threaded fastener (38) is received in coaxial apertures (36,40) in the mounting plates (21,28) for defining the pivot axis (38) of the extension screed (20) thereby permitting slope adjustment of the extension screed (20) relative to the main screed (10). Tightening of the fastener (38) draws the mounting plates (21,28) in tight engagement with each other thereby establishing the zero clearance pivot joint. This zero clearance pivot joint (38) thereby improves alignment between the main screed sole plate (16) and the extension screed sole plate (24) during paving operations, resulting in a higher quality road surface.

Abstract: A magnetically shielded room has four walls (22), a floor (24), and a ceiling (20). One of the walls has a doorway (26) therethrough, and a sliding door (32) is provided to close the doorway. Each of the four walls, the floor, the ceiling, and the door is formed of at least one layer of electrically conductive material (40) to exclude radio frequency energy from the interior of the room, and at least one layer of high magnetic permeability material (42) to exclude magnetic fields from the interior of the room. Preferably, at least the wall with the doorway therethrough and the door are formed of two electrically conductive plates (54) and a layer of high magnetic permeability material (58) on each of the plates, the electrically conductive plates of the wall being spaced sufficiently far apart that the sliding door slides into the space between the plates when the doorway is opened. In this preferred approach, the door is mechanically, electrically, and magnetically sealed to the doorway in the wall by inflating bladders (56) in the door that force the electrically conductive plates (54) of the door against the respective plates of the wall (70), and the high magnetic permeability layers (58) of the door against the respective layers of the wall.

Abstract: A spectral shift-producing subassembly (12) is composed of a plurality of sealed empty water displacement rodlets (30) incorporating a spectral shift-producing capability. Each of the rodlets (30) includes an elongated tube sealed at its opposite ends and having an axially-extending annular wall section (54) of reduced thickness compared to the thickness of the wall of the remainder of the rodlet (30). The respective reduced thicknesses of the axial wall sections (54) of the rodlets (30) can be varied to adapt the rodlets (30) to rupture at different times and permit water to enter the rodlets to produce an increase in the water/fuel ratio and thereby an increase in reactivity. The rodlets (30) can also have different levels of pressurization to initiate rupture at different times.

Abstract: A method of manufacturing a semiconductor device whereby a layer (12) containing Co or Ni is deposited on a surface (2) of a semiconductor body (1) bounded by silicon regions (3, 4, 5, 6) and regions of insulating material (8, 9), after which the semiconductor body (1) is heated during a heat treatment to a temperature at which the Co or Ni does form a metal silicide with the silicon (3, 4, 5, 6), but not with the insulating material (8, 9). On the surface (2) of the layer (12) containing the Co or Ni, according to the invention, a layer of an amorphous alloy of this metal with a metal from a group comprising Ti, Zr, Ta, Mo, Nb, Hf and W is deposited, while furthermore the temperature is so adjusted during the heat treatment that the layer (12) of the amorphous alloy remains amorphous during the heat treatment. In this way a metal silicide is formed on the silicon regions (3, 4, 5, 6) only and not on the regions of insulating material (8, 9) directly adjoining them, in other words, the method yields a self-aligned metal silicide.

Abstract: The clamp circuit of the present invention includes a comparator 9, a pulse signal generating circuit 10, an integrating circuit 12 and a subtractor 17. The comparator 9 compares a composite video signal with a threshold potential and detects a composite synchronizing signal. The pulse signal generating circuit 10 generates pulse signals S1 and S2 showing which of the detected composite synchronizing signal and a reference time period (t) is larger. The integrating circuit 12 corrects a threshold potential in response to the pulse signals S1 and S2 such that the pulse width of the horizontal synchronizing signal of the composite video signal corresponds to the reference time period t. The subtractor 17 subtracts the threshold potential from the composite video signal, so as to fix the DC level of the composite video signal at a prescribed potential. Since a threshold potential which makes constant the pulse width of the synchronizing pulse signals is generated and the video signal is clamped by using this threshold potential, the video signal including the synchronizing signal is made less susceptible to the influence of noise and the like, and clamping operation of the video signal can be done more accurately.

Abstract: Process for polymerisation of ethylene or copolymerisation of ethylene and at least one other alpha-olefin comprising from 3 to 12 atoms of carbon. The process involves the catalyst being prepared by (a) depositing an organo-metallic compound of aluminium on a dried refractory oxide, (b) drying the product at a temperature of between 200°C and 800°C, (c) contacting the product with a compound comprising chromium, (d) thermally activating the product at a temperature of between 350°C and 900° under a non-reducing atmosphere. The product is then used in the polymerisation with an organo-metallic compound of formula MR n  in which M is a metal selected from the group consisting of boron, aluminium, magnesium and zinc, R is an alkyl group made up of 1 to 12 atoms of carbon and n is a whole number corresponding to the valency of the metal M. Preferably the organo-metallic compound is present such that the atomic ratio M/Cr lies between 0.1 and 15. 
     The process enables the production of (co) polymers of ethylene having a higher melt index which can be easily moulded by extrusion or blow moulding into hollow bodies or film.
