Abstract: During warm-up of an image-forming apparatus such as a laser printer, the operation of a fuser unit contained therein is controlled by a method which includes the steps of: energizing a heater (310) in a heated roller (10) at substantially the same time as an initialisation process of the mechanical and electrostatic conditions of the machine is commenced in which process the heated roller (10) and a backup roller (12) are rotated together; stopping the rotation of the rollers (10, 12) after the initialisation process has been completed; monitoring the surface temperature of the heat roller (1) for a first predetermined period (T1 - T9) after the completion of the initialisation, and if the surface temperature has reached a set value within the first predetermined period, determining that the fuser unit (14) is ready for operation, and conversely, if the set value is not reached within the first predetermined period (T1 - T9), carrying out an additional warming-up process of rotating the heat roller (10) and the backup roller (12) again until the set value is reached, unless a second predetermined period (T6 - T1) has expired subsequent to the expiry of the first predetermined period (T1 - T9). 
     By employing such a method, the mechanical and electrostatic stresses imposed on the process elements (216, 220, 226) of the apparatus during warm-up may be reduced.

Abstract: A monobeam system for determining concentration changes of chromophore substance in a sample includes a flash lamp for passing a light beam through a sample containing the analyte. The values of absorbance by the sample at multiple wavelengths are measured and the optimum linear combination of absorbance values is determined to obtain a measure of chromophore concentration. Extinction coefficients for a chromophore is measured employing Deming's method and eigenvector transformations. A matrix reflecting the noise pattern of the system is determined. This matrix and the extinction coefficients are used in determining the coefficients for the optimum linear combination. An electronic module converts analog intensity data into digital data for five wavelengths. This is processed into absorbance values and concentration determinations.

Abstract: In a valve train for an I.C. engine, a cam shaft (1) has cams (2, 3)  formed with compound curvatures which allow the valve timing to be altered while the engine is operating, to suit the engine driving conditions by shifting the cam shaft (1) along its axis. To reduce the force necessary to shift the cam shaft along its axis the valve closure springs are replaced by closure cams (3). In some embodiments pivoting arrangements comprising a pair of ball (11) and socket joints (7) are provided to eliminate lateral sway of the rocker arms allowing precise adjustment of the valve timing when the cam shaft is shifted along its axis. In other embodiments the rocker arms are journalled on a rocker shaft provided with stops for preventing lateral sway. In some embodiments the closure rocker arms (15) have cupped ends in which either the valve stem retainer (17) or the valve stem seal is received.

Abstract: 2.1. Subscriber devices in the form of answering machines with information recording, call forwarding and remote interrogation are known. If the owner of the answering machine is travelling, the call signal, after the message of the caller has been recorded, can be automatically forwarded to a paging receiver via the European paging service. The answering machine contains an automatic dialler for forwarding the call. Furthermore, a paging service (City-Ruf) is known in which not only paging signals but also digits and short text (Display-Paging) are transmitted and displayed on the display device of the paging receiver. 2.2. Using a network gateway from the line-connected telecommunications network to a radio paging service, the novel subscriber device provides for fast information transmission of messages temporarily stored in the subscriber device. For this purpose, the subscriber device contains, in addition to the additional buffer store, a microprocessor which, using stored dialling information items, sets up a connection to a paging receiver and then reads out the temporarily stored message. 2.3. The novel subscriber device can be used in all communication networks for switched connections and ensures that a called subscriber who is travelling can respond quickly to a call. <IMAGE>

The piston (36) is formed on one end of a piston rod (40) subjectable to shearing stress and, in the position of readiness of the tensioning device, is pushed into the cylinder (30) by means of the piston rod. The piston rod (40) is supported at its other end on the guide part (12). Release is obtained by means of a mechanical release mechanism sensitive to the vehicle. Instead of a return stop, there is a return brake which reduces stress peaks in the belt system. …<IMAGE>…

Abstract: In an oxygen concentrator which is intended for aircraft use, a booster compressor (16) is used to increase the pressure of the product gas from the concentrator (15) in order to increase the amount of the gas which can be stored in a plenum (17). The booster includes two moving pistons (47,49) which are rigidly linked together and a series of check valves (44,54,57,59) which control the flow of gases through the compressor (16). One of the pistons (49) is driven by air from the rotary valve (31) in the concentrator (15), and the other piston (47) compresses the product gas for delivery to the plenum (17). 
     A small sample of concentrator product gas is monitored by an oxygen sensor (66) for oxygen concentration. Once the oxygen concentration has reached an acceptable level the booster compressor (16) fills the plenum (17) with product gas. Thereafter, if oxygen concentration of product gas delivered to the crew from the concentrator (15) falls below the concentration which is required at a particular altitude, the product gas stored in the plenum (17) is delivered to the crew. The oxygen sensor monitors the concentrator output product gas to the breathing regulator when the stored plenum gas is not being used.

Abstract: A class of torsionally-balanced submarine cables is disclosed which are highly coilable without exhibiting the undesirable tendencies of looping and kinking of its predecessors. Coilability is achieved in part by controlling the cable's torsional stiffness to bending stiffness ratio. Use of glass-reinforced polyester tape between and over the armor wires facilitates movement of the armor wire during coiling. The teachings of the present invention apply to cables experiencing strains in the elastic range.

Abstract: A method and apparatus for automatically adjusting the exposure of video images of the type that are commonly generated during endoscopic examination of tissue. The output of a video amplifier(24) is detected and compared(40) with an ideal value. A corresponding adjustment of amplifier gain is determined and such adjustment compared with a predetermined optimum range of amplifier gain. In the event that the calculated adjustment lies within such optimum range, the gain of the amplifier is adjusted accordingly. In the event that the optimum range is exceeded by the absolute value of the calculated adjustment, the exposure time of the camera sensor(14) and the gain of the amplifier(24) are adjusted in opposite senses whereby the amplifier is continuously operated within its optimum range.
