Abstract: In order to satisfy a market with an increasing number of flat key models, and the need to reproduce these keys very quickly, a universal clamp has been developed for facilitating the machining of their teeth from a master key. This clamp has a lower plate (100) and an upper plate (200), the peripheral parts (120, 220) of the facing bases interacting in the manner of jaws in order to clamp a longitudinal part of a bit (22) of flat keys whilst at the same time leaving the other longitudinal part of the bit (22) accessible. This clamp is characterised in that the said facing bases are hexagonal, and in that the form of the said jaws is different on each face of the hexagon, each of the said forms of the said jaws being compatible with the section of a particular type of flat key bit (22). <IMAGE>

Abstract: It has emerged that residues of hydrogen peroxide in human hair result in oxidation damage. This can be prevented with a water-soluble product which is in the form of a powder or tablet and which preferably contains 5 to 50 per cent by weight of ascorbic acid or the salts or derivatives thereof. The ascorbic acid, which is coated, for example, with silicone or ethylcellulose, can be stored in a formulation of this type for a relatively long time and dissolved in water only when used. This can take place with the aid of sodium bicarbonate with an effervescent action. A hair-care composition of this type is extremely well tolerated by hair and skin.

Abstract: The invention is characterized as a data processing architecture and method for multi-stage processing of mail, using knowledge based techniques. The system includes OCR-scanning a multipart address field of a mail piece at a sending location, the address field including at least two portions, a first stage routing portion (destination city, state, country, zip code) and a second stage routing portion (destination street address, building floor, corporate addressee internal routing). 
     At the sending location, the image of the entire address field is captured by an OCR head and stored in memory. A serial number is printed on the mail piece. The first routing portion is then converted into sorting signals to sort the mail piece to a truck at the sending location. 
     While the mail piece is in transit on the truck, the knowledge processor completes its analysis and is able to transmit by electronic communications link to the destination location, the information that the mail piece is on its way and the second stage routing information needed to automatically sort and deliver the mail piece to its corporate addressee.

Abstract: The invention concerns a suction roll (10) for a paper machine, on which the paper web is pressed towards the outer face of the roll mantle. The suction roll (10) is divided, in the axial direction of the roll, into at least three vacuum spaces (A₁,A₂,A₃). In the interior of the suction roll (10), there are at least two partition walls (17a,17b), by means of which the suction space (13) is divided into separate zones of negative pressure. The lateral vacuum spaces (A₁,A₃) in the suction space can be subjected to a higher negative pressure than the vacuum space (A₂) in the middle area of the roll, whereby the profile of negative pressure is formed such that the negative pressure increases across the width of the roll towards the lateral areas. The invention also concerns a method for producing a desired pressure profile for a suction roll.

Filed: 1990-09-04
Abstract: A regulator is responsive to an input signal proportional to the system supply voltage for adjusting the current flowing in the field windings of an electrical alternator (14) which controls the output power thereof. The primary regulation loop (22,23,26,30) of the regulator generates a pulse train having a duty cycle inversely proportional to the amplitude of the input signal while an oscillator provides a sawtooth signal at a predetermined frequency which controls the response frequency of the regulator. The regulator limits the rate of increase in the duty cycle of pulse train upon detecting a decrease in the system supply voltage by converting the duty cycle of the pulse train to a charging signal for developing a voltage across a capacitor (36) proportional to the duty cycle of the pulse train. The voltage across the capacitor is compared to the sawtooth signal and triggers a latch which disables the output signal of the regulator as the duty cycle lengthens in response to the decrease in the system supply voltage. The voltage across the capacitor is increased each oscillator cycle until the duty cycle reaches the value required to support the output, power of the alternator.
