Patent DE-3363719-D1 (DE)
Title: Hydrogen peroxide compositions
Inventor: SANDERSON WILLIAM RONALD
IPC: C11D3/39
Filed: 1983-04-13
Granted: 1986-07-03
Abstract: The effectiveness of hydrogen peroxide for bleaching and disinfecting at ambient to hand hot temperatures can be enhanced by reaction with a peracid generator (activator), but the provision of storage stable concentrated aqueous liquid premixes of hydrogen peroxide and activator presents many problems arising from the physical and chemical properties of the components. The present invention provides aqueous acidic emulsions of hydrogen peroxide and enol esters, preferably at a pH of 2 to 5 and containing a slight excess of hydrogen peroxide over an equivalent mole ratio to enol ester activator of 1:1. The concentrations of the components of some preferred emulsions are selected in the ranges of 3 to 20% hydrogen peroxide, 30 to 85% water, 10 to 30% enol ester (%s by weight based upon the emulsion) and from 10 to 70% by weight based on the enol ester of emulsifiers. In preferred compositions, the activator is selected from vinyl or isopropenyl or but-1-enyl or cyclohex-1-enyl acetate or benzoate and divinyl adipate or phthalate, and 1,5-diacetoxypenta-1,4-diene. The compositions can be used as such or upon dilution with aqueous media and in conjunction with detergent compositions, and for cleaning and disinfecting absorbent or non-absorbent materials.
Patent DE-3365234-D1 (DE)
Title: Needle-valve injection nozzle
Inventor: SHARP RICHARD FELIX
IPC: F02M61/20
Filed: 1983-03-19
Granted: 1986-09-18
Abstract: A control device and method for opening and closing the nozzle of a fuel injector. The control device includes first and second cavities which are formed in the body of the fuel injector, with the second cavity being located close to the nozzle. First and second variable pressure supply chambers are connected to the nozzle and to the two cavities by several fluid passages. A spool valve and a needle valve are positioned in the first and second cavities, respectively, with the spool valve abutting a stem which projects into and terminating in the second cavity. Also situated in the second cavity between the stem and the needle valve is a spring which forms a link therebetween. The spool valve is pressure-actuated by a difference of pressure in the first and second pressure chambers to move between an open and a closed position. In the open position, fluid flow from one of the pressure chambers is permitted through the spool valve and to the second cavity. As the fluid pressure in the second cavity increases to a value greater than the compressive force of the spring, the needle valve will open and allow fluid flow through the nozzle of the fuel injector. As the spool valve moves to its closed position, it compresses the spring further and then urges the needle valve to close. The needle valve closes prior to a drop in fluid pressure in the second cavity.

Title: Communication system
Inventor: KELLY MICHAEL BERNARD
IPC: G06F11/20
Filed: 1984-05-11
Granted: 1987-05-14
Abstract: In a telecommunication system with a number of units (Ula-Una, Ulb-Unb) for control purposes and also for subscriber facilities, each such unit is duplicated, as is the system controller (SCa, Scb). There are two local area networks (1,3), each of which interconnects one system controller and one unit of each pair of units. When one network is to be isolated, e.g. for servicing or when a fault occurs, its controller detects that condition, and isolates that network by relay circuitry in the termination (T2, T3) of the bus. Another version of the system uses local area networks of the closed ring type. In certain cases the units, etc., may be triplicated.

Title: Rolling stand for supporting work rolls by means of supporting rollers
Inventor: BALD WILFRIED
IPC: B21B29/00
Filed: 1984-07-13
Granted: 1988-06-09
Abstract: A roll stand has a frame having two sides spaced apart transversely of a workpiece travel direction and formed with throughgoing windows and a pair of vertically spaced traverses extending between the frame sides. Two outer backup rolls centered on parallel axes transverse to the direction having journal blocks vertically displaceable and guided in the windows of the frame sides. Upper and lower guide elements vertically displaceable in the windows between the outer-roll blocks carry the journal blocks of two inner backup rolls. Pairs of positioning actuators in the windows vertically between the inner-roll blocks carry supports which carry second upper and lower guide elements vertically displaceable on the supports. The positioning actuators are expansible and contractile to displace the second guide elements in the direction. Two working rolls between and parallel to the other roll axes each have two journal blocks fitted to and axially slidable in the second guide elements. An insert carried in the traverses carries rows of bracing rollers which extend axially along the working rolls between same and the traverses. The insert, bracing rollers, and upstream positioning actuators form an integral bracing unit and at least one of the windows is shaped such that the bracing unit can be withdrawn axially through the frame side. Rows of bracing actuators braced in the direction between the rollers and the traverses can press the rollers opposite to the direction against the working rolls.

Title: Apparatus for bending glass sheets
Inventor: NITSCHKE DEAN MICHAEL
IPC: C03B35/14
Filed: 1984-10-17
Granted: 1989-04-20
Abstract: @ An apparatus disclosed for use in bending heated sheets of glass transported generally horizontally on a conveyor within a furnace heating chamber includes a holder and a counter-balanced bending member, both of which are located above the conveyor in a spaced relationship such that a heated sheet of glass can be transported under the holder. The holder includes a curved, downwardly facing surface with spaced openings in which vacuum is drawn to receive the glass sheet from the conveyor. Gas, such as air, is blown upwardly from below the conveyor against the heated sheet of glass such that the sheet is moved upwardly and into engagement with the curved surface of the holder. The bending member then moves downwardly below the holder surface and thereafter upwardly against the heated sheet of glass to provide bending thereof to the curved shape of the holder surface. The bending member then moves back to its home position above the holder surface. A carrier mold ring moves under the supported glass and the vacuum is then terminated so the glass drops onto the ring and bends under the bias of gravity in a manner that allows the glass to be further bent. Subsequently, the mold ring is moved from the furnace to a quench unit that tempers the glass.
