Patent EP-0066697-A1 (EP)
Inventor: ANASTASSIOU DIMITRIS
IPC: G06T9/00
Filed: 1982-04-21
Abstract: The present invention relates to a method and system for compacting grey-scale image data. The system permits the use of a «zero bit» per pel mode for the data transmission (1 «error bit» per pel actually transmitted) and provides for the automatic detection of the particular variable length compression code utilized for transmitting the quantized error (Ey) for a particular pel. Utilizing the concepts of the present invention compression rates of approximately 1.5 bits have been obtained. The system comprises, first prediction means (28) for predicting the grey scale value of a current pel which is to be transmitted, utilizing the values of previously transmitted pels, second prediction means (26) for predicting the code which should suffice for transmitting the quantized error for correcting the predicted pel grey scale value to approximately the true value of said pel, means for determining the code which is actually needed to encode the quantized error, means (30) for producing a first special purpose code bit when the predicted range of codes for encoding the quantized error is sufficient and a different bit when it is insufficient, and means (30) for generating a first quantized error code when the predicted range of codes is sufficient and a second code when it is insufficient.

Abstract: 1. A pilot signal demodulator for stereo television reception or television-2-channel sound reception, as the case may be, characterised in that a periodic signal (fH ) transmitted to the receiver with a video signal is used as a theoretical value for a control circuit functioning in accordance with frequency synthesis techniques (PLL system), connected to the theoretical value input of the phase detector (PD) of said control circuit, that the output of the follow-up oscillator (VCO) of this control circuit is connected to the actual value input of the phase detector (PD) via a controllable phase shifter (PHS), that further the signal (fP ) to be demodulated serves to set two mixer stages (M1, M2) whose other signal inputs are influenced by a signal from the output of the follow-up oscillator (VCO) in such a manner that this oscillator signal is fed directly to the first mixer stage (M1) and with a phase shift of 90 degrees to the second mixer stage (M2), and the output signal of the first mixer stage (M1) is finally fed to the input of the phase shifter (PHS) via a low-pass filter (G) to control the operating state of the phase shifter (PHS), whereas the demodulated signal (AM) can be tapped at the output of a further low-pass filter (TP) controlled by the output of the second mixer stage (M2).

Inventor: GALSTER HANS-PETER
IPC: B65H9/10
Filed: 1982-10-09
Abstract: A device for registering a sheet with a side stop at either one of the opposite lateral edges of a feed table in a printing press. The device includes a housing having a top surface which is flush with the feed table. A suction head is flushly recessed in the surface of the housing and mounted in a slide in the housing for limited reciprocating movement. The housing is shiftable between alternative working positions at the respective lateral edges of the feed table. For driving the suction head timed with the arrival of a sheet, a drive shaft is provided in the housing having a pair of face type cams spaced axially from one another cooperating with a cam follower which is secured to the suction head in a position between the cams. Springs are provided for biasing the suction head in opposite directions. A shiftable yoke selectively engages the springs with the suction head so that the cam follower engages a selected one of the cams. A rotary value on the drive shaft applies suction to the head timed with the movement of the head toward the adjacent side stop. The cams are in mirror image, that is, 180 DEG  out of phase, so that the sheet moves into contact with one of the side guides, with application of suction, timed with the feeding of the sheet on the feed table regardless of which side stop is being employed. In a modified form of the invention application of suction to the sheet is followed by a puff of compressed air.

Abstract: Two valve elements (46, 48) of which one (46) can be supported on a control cylinder (12) and the other (48) is connected to a control piston (40) together separate inside the control cylinder (12) an inlet chamber (14) from an outlet chamber (18) when the control piston (40) is moved from an open position into a closed position. A spring (62) holds, with pretensioning, the control piston (40) in the open position counter to the pressure in the outlet chamber (18) until this pressure exceeds a fixed switching pressure. The pretensioning of the spring (62) and thus the switching pressure can thus be set. The spring support (56) is screwed to the control piston (40); as a result of which the space requirement of the valve is not substantially greater than a comparable, non-adjustable valve. <IMAGE>

En cas de feu, il est utilisé sur le feu et se place entre le combustible et la flamme en séparant l'un de l'autre. Etant donné qu'ils sont glacés ou froids, ils éliminent ou réduisent considérablement la production de gaz émanant de la surface du liquide et réduisent l'ampleur du feu. Etant donné qu'ils sont volatiles à la température de la surface du liquide enflammé, ils produisent un nuage non combustible qui étouffe le feu.

Abstract: A method and oven equipment for cooling a charge after thermal treatment. The charge, which is located within a closed chamber, is cooled by blowing in cooling gas. The cooling occurs as a function of the actual conditions of the charge at a predetermined speed, and a uniform distribution of temperature within the charge is assured. For this purpose, the temperature distribution in the charge is measured by temperature sensors, and the intensity and/or direction of the flow of the cooling gas can be changed if deviations from the predetermined theoretical values occur. The wall of the closed treatment chamber of the oven equipment contains a plurality of gas passages which can either be closed off, or are permeable for gases yet impermeable for heat rays. Cooling gases are conducted through the chamber via control valves. The cooling gas is circulated with the aid of a blower unit along with a gas cooler. A temperature control system based on desired-actual-comparisons operates the control valves and the closure elements of the gas passages.

Abstract: A low expansion alloy on the basis of iron is formed by an intermetallic compound having a cubic crystal structure of the NaZn 13  type having a nominal composition LA(Fe, Co,X) 13 , wherein X is Si or Al. By subjecting the present intermetallic compound after melting to a tempering treatment at 800-1,000°C and cooling it in an accelerated manner, a brittle material is obtained which can be ground to form a powder. From this powder, articles having any desired (optionally complicated) shape can be produced by means of powder metallurgy. By mixing powders of two different intermetallic compounds, a material can be obtained having a substantially negligible coefficient of linear thermal expansion in the temperature range from 0°C to 200°C.
