Inventor: WHITCOMB DAVID R C O MINNESOTA
IPC: B41M5/32
Filed: 1987-08-05
Abstract: Thermographic materials are colorless when unexposed, but provide an intense dark image when thermally addressed. The materials comprise white ferric organophosphate, ferric organophosphinate, or ferric organophosphonate in a clear binder with a colorless catechol or polycatechol held in said binder in solid solution. The choice of substituents on the catechol nucleus can give a change in the color of the thermal image together and provide good near infrared absorption. Use of mixed catechols can give achromatic black images. These combinations of materials show high stability at ambient temperatures.

Abstract: The present invention relates to a method and an arrangement for steering a vehicle of the kind which is constructed to be steered for straight ahead movement or for turning to the left or to the right in response to activation of a steering device (6), by causing left and right traction devices (11, 21) on the vehicle to move at mutually the same speed or at mutually different speeds. 
     When carrying out the method according to the invention, or when using an arrangement constructed in accordance therewith, steering is effected through the activation of clutch devices (14, 24) and brake devices (13, 23) on the vehicle, by establishing pressure changes in individual hydraulic steering control pressures, in a direction dependent on the result of a comparison made between a steer control set-point value and a steer control real-value. In this regard, the steer control real-value is generated with the aid of sensors (16, 25) which detect the rotational speed of the left and right traction devices of the vehicle. According to the invention, pressure changes are primarily effected in a hydraulic steering control pressure for one clutch device, while pressure changes in the hydraulic steering control pressure for a brake device associated with the same traction device as the aforementioned one clutch device are effected in a manner such that no braking effect is established until a given total change in the hydraulic steering pressure for the brake device is found insufficient to steer the vehicle in the manner desired.

Abstract: Reference signals having a predetermined frequency interval are produced in use of a wavelength tunable laser device (1) and an optical resonator (5). Plural laser devices (8-10) are controlled to radiate light outputs with oscillation frequency separation. The light outputs and a frequency swept light output of the wavelength tunable laser device (1) are combined, and then converted to beat signals. The reference signals and the beat signals are compared to detect time differences of signal occurrance timings. The plural laser devices (8-10) are driven with the oscillation frequency separation, such that the time differences become a predetermined value. Where a beat pulse is not produced due to a fault in at least one laser device among the plural laser devices, a dummy pulse is produced to produce a signal of the time differences. The laser device of the fault may be driven with an injecting current varying in a predetermined range to produce a beat pulse.

Abstract: A signature conveyor comprises a first conveying means (64) which conveys signatures (40) in sequence to a delivery station (60). At the delivery station (60), the signatures (40) are transferred in sequence to a receiving conveying means (74). A shaping device (126) is positioned at the delivery station (60) in order to reinforce the signatures (40) by shapings (132) being formed in the signatures (40), which shapings extend between their front and their rear end parts (46, 48). Although the shapings (132) are only maintained in the signatures (40) temporarily, the shaping device (126) is mounted sufficiently near to the receiving conveying means (74) for a shaping (132) in a signature (40) to be able to be maintained while the front end part (46) of the signature (40) moves towards the receiving conveying means (74). Thus the shaping device (126) is situated at a distance from the receiving conveying means (74) which is less than the distance between the front and the rear end parts (46, 48) of the signatures (40). <IMAGE>
