Title: Process for winding strip on to tyre building drum - detects ends of strip and has automatic control circuitry to ensure that they meet precisely on the drum without overlap or gap
Inventor: SHIMIZU KENTARO
IPC: B29D30/30
Filed: 1991-03-15
Abstract: In a process for winding strips in a tyre building machine the strip is fed to a build-up drum by a feeding device and picked up on the drum while regulating the feeder and drum speeds, and the two ends of the strip are joined together. The feed and peripheral speed of the drum are made equal; a leading part of set length of strip is placed on the drum; the position of the trailing end of the strip on its feeder is measured so as to provide the length of the following section; the ratio of feed speed to drum speed is set to L/Lo, where L is the length of the following section and Lo the remaining circumferential length of ther drum; the following section of strip is picked up but only when this ratio L/Lo is within a certain band, whilst picking up the following section is halted if the ratio is outside that band. ADVANTAGE - The process registers the ends of the strip precisely so that they have neither an overlap nor a gap between them. The patent also covers the method and set-up  where the overlapping ends of a strip on the drum can automatically be measured.

Title: Cut fabric sepn. without manual work - gives clamping action to waste part to separate cut pattern sections by relative movement
Inventor: BLANCK STEFAN
IPC: A41H43/02
Filed: 1992-02-18
Abstract: After a stack of layered textile fabrics has been cut ot stamped to give a number of pattern shapes, the edge of the waste portion of the stack is clamped. A relative movement is applied parallel to the patterned cut surfaces so that the waste material and cut pattern material are partially sepd. The spreading action is continued until the waste and cut pattern portions are free of each other, to be sepd. continuously or in stages. The clamped waste portions of the material is moved upwards from the laying surface while the stamped sections remain in place through their own weight or by retainers for separation from the waste. The waste material movement is on the level of the laying surface and the cut material moves free on a downwards plane. The relative movement between the stack and the sepn. zone is by a sliding movement of the stack or movement of the clamp. ADVANTAGE - The operation gives a clean and mechanical sepn. of the fabric layers required for garment making from the waste, without manual work by operatives.

Patent DE-4212203-A1 (DE)
Inventor: ROWLAND WILLIAM P
IPC: G02B5/02
Filed: 1992-04-10
Abstract: A retroreflective material retroreflects a white coloration for light beams impinging thereon at night and appears to have the coloration of an underlying support in daylight. This material utilizes retroreflective sheeting (24) having closely spaced microretroreflective formations (22) on one surface, and a transparent adhesive (28) in a pattern over that surface so as to leave the predominant portion of the surface free from adhesive (25). A transparent backing element (26) is adhered to the sheeting by the adhesive (28), and it extends in a plane generally above the formations (22) to leave the formations (22) in the predominant surface area exposed to surface of the sheeting and impinging upon the formations the atmosphere thereabout. Light rays entering the other (22) of the predominant surface area are retroreflected by the interface with the atmosphere, and those impinging upon the formations (22) in the area coated by the adhesive (28) pass through the adhesive (28) and the backing (26) for reflection and refraction from the underlying surface, thereby evidencing its color in daylight. <IMAGE>
Patent DE-4213880-A1 (DE)
Inventor: BODE FRIEDRICH-WILHELM DIPL IN
IPC: H04B7/26
Filed: 1992-04-28
Abstract: A system is proposed for bidirectional electromagnetic transmission of data signals between at least two fixed stations and one mobile station. The fixed stations transmit the data signals to the mobile station synchronously in downlink mode, their carrier frequencies being different. The data signals are transmitted in uplink mode according to the semi-passive transponder principle from the mobile station to the fixed stations. The data signals of the mobile station are frequency-modulated at the different carrier frequencies of the fixed stations. This arrangement achieves an improvement in the reliability of the bidirectional data transmission. A preferred use is for data exchange for systems controlling traffic between fixed beacon devices and moving vehicles. <IMAGE>

Title: Hydrogen fluoride recovery from sulphuric acid or gas contg. fluoride - by spraying acid in countercurrent to gas into reactor with various temp. zones and continuous discharge of gas and acid
Inventor: RURLAENDER ROBERT
IPC: B01J19/12
Filed: 1992-07-13
Abstract: HF recovery from a source (I) contg. fluoride involves spraying a liquid (II) contg. H2SO4 into a reactor and passing a gas (III) in countercurrent to the (II) droplets falling through the reactor, (I) being a constituent of (II) and/or (III). The novel features are that: (a) a temp. gradient is produced in the reactor, which is divided into various zones in which different reactions predominate, depending on the temp. gradient; and (b) a gas phase (IV) contg. HF and a mixt. (V) of mainly liquid H2SO4 are discharged continuously from separate outlets. Also claimed is the appts. to carry out the above recovery process. This has a closed hollow pipe with cover and base, a jet for spraying (II) into the pipe, a (III) inlet, outlets for (IV) and (V) and a microwave source. It may also have a heater for the bottom, temp. controls and a meter showing deg. of filling. USE/ADVANTAGE - The process is used for producing regenerated acid for etching semiconductors, for purifying HF or for recovering HF from H2SiF6, CaF2 or SiF4 (claimed). The process avoids deposition of SiO2 on the reactor walls and the concn. of SiF4, if used, does not limit its efficiency.

Title: Active suspension for vehicle with high frequency vibration damping - has bandpass filter for processing suspension movements and with variable reaction shock absorbers
Inventor: KIMURA MAKOTO
IPC: B60G17/015
Filed: 1992-08-06
Abstract: The vehicle suspension has variable dampers on each strut, with the damping coefficient of any damper adjustable during the displacement of the strut. Longitudinal motion sensors and processing circuits determine the vibration of the suspension and regulate the dampers. A bandpass filter eliminates high frequency vibrations, such as are transmitted when the dampers are set hard. The motion sensors compute the acceleration of the sprung mass or the acceleration is directly measured by inertial sensors. The bandpass filter comprises a low pass filter and a high pass filter, providing a combined effect of a band between 0.5 Hz and 3Hz. ADVANTAGE - Improved comfort, reduction in high frequency vibrations.
Patent DE-4232702-A1 (DE)
Inventor: POPA HEINZ DR ING
IPC: H02H3/05
Filed: 1992-09-30
Abstract: An earth leakage or differential current circuit breaker (residual current device) has contact points (17) (which are arranged in a network having at least one forward conductor and one return conductor), a transformer (10) whose primary windings (11, 12) are formed by the network conductors and whose secondary winding (15) is connected to a tripping relay (17), via a storage circuit (16). The tripping relay (17) acts on the latching point in a latching mechanism (18), and the latching mechanism acts on the contact points (19). In order to avoid failures after a relatively long operating time or towards the end of the useful life of the tripping device (17), the storage circuit (16) has an evaluation circuit (20) which is connected to the tripping relay (17) via a signal line (21). As a result of the armature movement of the tripping relay (17), a pulse signal, which is detected by the evaluation circuit (20), is produced during the tripping process. If this pulse signal does not occur as a result of the tripping relay (17) not tripping, then the tripping energy emitted by the store of the storage circuit (16) is increased.   <IMAGE>
