Abstract: PCT No. PCT/SE83/00195 Sec. 371 Date Jan. 13, 1984 Sec. 102(e) Date Jan. 13, 1984 PCT Filed May 17, 1983 PCT Pub. No. WO83/04355 PCT Pub. Date Dec. 8, 1983.The invention relates to a method and apparatus in duplex transmission of digital information between subscribers connected to terminals associated with each other in a telecommunication network of the time multiplex type in which information is transmitted in the form of binary words in specially assigned time slots, of carrying out with the aid of parity check, during traffic in progress, through-connection testing for checking that a correct connection has been set up after a switching path has been established. The through-connection check is started and detected in the same station (terminal). After detected correct parity, which is done with the aid of a parity check means (M1) and a comparison circuit (OR), there is generated a parity bit with intentional incorrect polarity for sending on the line towards the next station. Generation of desired parity is done with the aid of an apparatus including a local processor (MP), a control memory (CM), a counter (TR) and said comparison circuit. All stations along a switching path are of equal value and contain the same means. A central processor assigns one of the stations (TCT), at the setting up of a connection, to be the control station for the through-connection test. The control bit with intentionally incorrect parity is switched straight through remaining switching points and is looped in the line terminal (PCM2) where information from-the B subscriber is received. The loop connection is carried out with the aid of a parity check circuit (M2) for extracting the parity bit from the terminal side, and a further parity check circuit (M3) for the loop formation itself and feeding out the parity bit back towards the TCT station. A check is made in the latter that it is the intentionally erroneous parity bit which is detected, and if this is the case the correct parity is sent, subsequent to which it is awaited that the correct parity will traverse the switching path and once again be detected in the TCT station. After this detection, a signal is sent to the central processor that the through-connection test is completed, after which this control is broken off and normal parity monitoring takes over, the latter not being embraced by the invention, however.

Abstract: The invention disclosed shows a device, method and system for installing threaded masonry anchors. A plate is used to control the rate of axial penetration of the anchor into a masonry structure. An opening in the plate allows engagement of the anchor with the plate. Rotation of the plate is prevented by various means. As the anchor advances and forms threads in the structure, the plate may be used to resist axial forces on the anchor in either axial directions thereby precluding stripping of threads formed in the masonry structure.

Abstract: A composite thermal shield includes an external solid layer of heat and corrosion-resistant metal bonded to a permeable layer of metal. The composite is mechanically affixed to the substrate metal of an engine component, by a method wherein the substrate metal becomes entrained within the interstices of the permeable metal layer. In a first preferred form the permeable metal layer is comprised of a fibrous stainless steel woven wire mesh which is sintered or brazed to the external stainless steel heat and corrosion-resistant layer. In a preferred process, an aluminum substrate piston is formed to include the composite shield, whereby the aluminum is pressed into the permeable layer during formation of the piston in a mold. In a second preferred form, the piston includes an insulation layer wherein two layers of stainless steel wire mesh have an intermediate stainless steel layer sandwiched between them. The bottom layer of wire mesh is subjected to the afore-described mechanical bonding with the substrate aluminum, while the upper layer, positioned between the top and intermediate stainless steel layers, operates purely as an insulation layer.

The individual flow control components are all dampers, and those (14,18) for control of air currents to the evaporator are operated in pairs by a motor, whilst another motor operates those (20,22) controlling air currents to the condenser. The two motors are in turn controlled by the common adjuster. A heating battery (24) is incorporated, and is used when the outside temp. is so low that the condenser alone cannot heat the air in the equipment, as during the worst part of the winter. Fans (26,28) impel air from the conditioning equipment to the building and to the exterior.

Abstract: A circuit (8) generates a control signal (is) which uses the information to produce a guiding signal for the missile or projectile (7). Other information based on experience and/or calculation in respect of the missile or projectile flight direction (I1, I2, I3 ... In) towards its target in respect of distance and position between the radar centre of gravity and the tartarget centre of vulnerability (SC) is stored in a memory. With establishment of the flight direction, the circuit generating the guiding signal receives from the memory the information covering the flight direction and other details, using it to alter the missile or projectile course (12) towards the target centre of vulnerability (SC). The target aspect in the flight direction is determinable using an angle between the missile or projectile and target speed vectors, and a second angle between the projection of the missile speed vector on a plane at right-angles to the target rolling axis and a plane characteristic for the target. The second angle is determined using the target acceleration vector and knowledge about the direction of the force of gravity.

Abstract: A method and apparatus for storing and reading digital information, in which the recorded information is protected by a double symbol correcting code involving interleaving between the codes and also employing an additional, optional error correcting code. The information is organized in sectors, which are arranged such that following the synchronization and header information sub-header information is provided to indicate different sub-modes of operation of the playback apparatus. During playback, when a first sub-mode indication value is detected, this means the sector contains further error protection information, that is, the optional error correcting code, for which purpose a special decoder is activated. When the sub-mode detector detects a second sub-mode indication value, this means that further user information is present at the location where the optional error protection information would have been, and the special decoder is not activated.

Abstract: The invention concerns a method and a device for tightening threaded joints in two subsequent steps, namely a first step during which a joint is tightened to a predetermined torque snug level and a second step during which the joint is further tightened up to a final predetermined pretension level. During the second tightening step the torque delivered by the power tool (10) comprised in the device is gradually increased at a rate exceeding the highest torque rate expected from the joint to be tightened. The power tool (10) comprises an electric brushless AC-motor which is supplied with power from a variable frequency output inverter (11), and the gradual increase in output torque from the power tool (10) is accomplished by the phase lag in the AC-motor as a result of a gradually increased output frequency from the power supply means (11).
