Title: A method of socketing a pipe
Inventor: JOHANSSON MATS
IPC: B29K101/12
Filed: 1996-09-20
Granted: 1999-04-29
Abstract: A method of socketing a pipe of oriented plastic having an annular groove inside the socket. An end portion (15) of the pipe is pushed onto a cylindrical mandrel element (11) and the region (l1) of the end portion at the opening thereof where the groove is to be located is heated to a temperature above the glass transition temperature of amorphous plastic and the crystalline melting point of crystalline plastic, respectively. The rest of the end portion is maintained at a temperature below the glass transition temperature or the crystalline melting point, respectively. The end portion (15) when said region is at a temperature above the glass transition temperature or the crystalline melting point, respectively, is pushed onto a second mandrel element (13) axially aligned with said first mandrel element the bottom portion of the socket being formed by said second mandrel element (13). The rest of the end portion is expanded to form the bottom portion of the socket. The end portion of the pipe is cooled and is then withdrawn from the mandrel elements.

Title: Injection of substances into high temperature liquids
Inventor: BATES KENNETH WILLIAM
IPC: C22B/
Filed: 1987-02-18
Granted: 1989-07-20
Abstract: Gas injection into a metal melt, accompanied if desired by powdered or solid treatment substances, is by way of a nozzle (14) inserted into the wall (12) of a melt-containing vessel (10). The nozzle bore (18) initially has a stopper (20) at its inner end and a delivery pipe (24) smaller than the bore (18) is movable therein. Before injection, the pipe (24) and bore (18) adjacent the stopper (20) are cooled by gas. By thrusting the pipe (24) against the stopper (20) while sufficient gas flow and pressure is maintained, the stopper is dislodged and the gas will enter the melt as a jet which leaves the pipe (24) at a velocity equalling or exceeding Mach 0.5. Melt enters the clearance between the pipe (24) and bore (18) but, due to the pre-injection cooling, rapidly freezes locking the pipe safely in the bore.

Title: Method and apparatus for determining the data rate of a received signal
Inventor: BUTLER BRIAN K
IPC: H04B1/707
Filed: 1994-06-20
Granted: 1997-11-13
Abstract: A system for determining the rate at which data has been encoded in the receiver (12) of a variable-rate communications system. The data is received in symbols that are grouped in frames. When data is transmitted at full rate, the frame is filled with symbols. When the data is transmitted at less than full rate, symbols are repeated within a frame until the frame is full or the symbols are spaced apart within a frame. At an encoding rate of one fourth the full rate, for example, each symbol in the frame is repeated four times or data is transmitted one quarter of the time. The incoming frames are decoded, for example by decoder (48), and re-encoded, for example by encoder (76), at each possible data rate. A comparator, for example comparator (84), compares the re-encoded symbols with the originally received symbols and a counter, for example counter (100), counts the number of symbol errors. Each decoding process produces an indication of the quality of the decoding process which may include Cyclic Redundancy Check (CRC) results, for example CRC (120), or Yamamoto Quality Metrics. The counted errors and the quality indication comprise an error metric which is passed to a processor, for example microprocessor (56). The processor analyzes the error metric for each data rate and determines the most probable rate at which the incoming symbols were encoded.

Title: A method of forming a paper web
Inventor: HERGERT RICHARD E
IPC: D21F9/00
Filed: 1991-02-19
Granted: 1994-11-24
Abstract: A method is disclosed for forming a paper web having a low tensile ratio. The method includes the steps of ejecting stock substantially horizontally from a headbox, and receiving the rejected stock onto a substantially horizontally disposed looped first wire, moving at substantially the same speed and the same direction as the ejected stock. The arrangement is such that a first portion of water is removed from the ejected stock downwardly through the first wire during passage of the ejected stock through an initial dewatering zone. The partially dewatered stock is sandwiched between the first wire and a looped second wire, the wires defining therebetween a secondary dewatering zone for further dewatering the ejected stock. A second and third portion of water are removed downwardly and upwardly, respectively, through the first and second wires during movement of the ejected stock past a curved shoe. The curvature of the secondary dewatering zone is reversed such that the wires extend around a curved inverted box connected to a source of partial vacuum, so that a fourth portion of water is removed upwardly through the second wire into the curved box. The arrangement is such that a gradual dewatering of the ejected stock is accomplished during passage of the stock through the initial and secondary dewatering zones, thereby inhibiting removal of fines from the ejected stock and minimizing the tensile ratio of the resultant web.

Title: Flux-coated sleeves for electro-slag welding - using separate outer rings of flux to prevent short circuits
IPC: B23K25/00
Filed: 1969-03-26
Abstract: A consumable sleeve for electro-slag welding consists of a steel tube with outer rings of flux located at fixed distances. The rings are >=2.6mm thick, =200mm long, and are bonded to the tube with a gap of =100mm between the rings; the end-faces of the rings taper from the outer dia. of the tube to the periphery of the ring, i.e. forming truncated cones. As an alternative, the flux can be arranged as a spiral round the tube. Water-glass is used both as a flux binder and to bond the rings to the tube; the sloping end faces of the rings prevents slag (which s fed separately) from lodging on the rings. The thickness of the rings prevents arcing between the sleeve and the plates being welded.

A control unit selects the particular drawing which is moved sideways to clear the rack. The drawing falls into the bottom half where it is transported by a belt drive to a processing station. After processing it is transported to a handling unit that raises the drawing to align with those in store. At this point either the drawing is ejected from the handling unit or is relocated in the storage unit.
Patent DE-1931093-B2 (DE)
Title: Rheostatic braking system for commutator motor - with chopper circuit control of field to regulate braking effort
IPC: H02P3/12
Filed: 1969-06-19
Abstract: The motor (1) comprises an armature (1a), field winding (1b) and interpole (1c). For the braking condition the armature is connected to a fixed loading resistance (2), and the field shunt connected with a chopper circuit (3) in series with the winding which is also bridged by a free wheel diode (4). Auxiliary ballast resistors (5, 6, 7) may be included if necessary. Control of the braking effort is by variation of the mark-space ratio of the chopper. Thus at high machine speeds the current flow through the field is of short duration, but increases as the speed falls until the resistive load (2) is virtually short circuited. The control is free from contactors, and contains no capacitors which could be the source of unwanted oscillations or resonance.
