Title: Frost-resistant apparatus for avoiding flat-roof damage caused by temperature stress
IPC: F24S10/70
Filed: 1988-04-13
Abstract: The invention relates to a frost-resistant apparatus for avoiding flat-roof damage caused by temperature stress, along with the simultaneous possibility of using the cooling water for heating up swimming-pool water or pre-heating service water. The apparatus comprises a system of flat, box-shaped elements which are closed on all sides, are laid directly onto the flat roof and in which a heat-exchanger pipe which extends over the entire surface and is fitted in serpentine form deals with the flat-roof cooling. The straightforward plugging process renders the extremely inexpensive system particularly easy to mount and maintain. <IMAGE>

Title: Computer-controlled laser drawing device having an arrangement for switching on the laser beam at the beginning of a line of a drawing sheet
Inventor: VEDDER HANS JOACHIM DR RER NAT
IPC: G06K15/12
Filed: 1988-04-15
Abstract: A computer-controlled laser drawing device having an arrangement for switching on a laser drawing beam (S1) at the beginning of a line of a drawing sheet (F), the drawing device having a laser (L), an acoustic-optical modulator (AOM) by means of which the drawing beam (S1) is modulated corresponding to the desired drawing, a plurality of lens systems (L2 to L4) and a polygonal mirror (AX). The drawing device is so designed that a reflection light barrier (LS) is assigned to the polygonal mirror (AX) in such a way that when the polygonal facets (K) of the said mirror move, said light barrier delivers a signal as a result of differences in reflection to an electronic time delay element (T) connected to the modulator (AOM), by means of which element (T) the drawing beam (S1) is switched on. A photodetector (D) is arranged in a position in which the drawing beam (S1) would encounter it shortly before reaching the drawing sheet (F) and beside the latter, a signal for switching off the drawing beam (S1) being output by means of the photodetector into the time delay element (T) when the drawing beam (S1) encounters the photodetector (D), and the modulator (AOM) being switched on again at the beginning of a line by the time delay element (T) after a further prescribed time interval. <IMAGE>

Title: Shift register adder circuit in 51111 code and basic adder circuit for 54321 code and 5211 code
Inventor: MERKLE PAUL
IPC: G06F7/491
Filed: 1988-10-29
Abstract: The shift register adder circuit according to the subject of the invention processes the value 5 in a dual full adder (10), and does not have an adder shift register with flipflops which are controlled by the clock cycle, but flipflops which are connected so that a flipflop high content is displaced by one flipflop to the right if the flipflop to the right of it has only a low potential content. The use of this principle is made possible by the use of 2 gate circuits (40 and 50), of which gate circuit (40) is first triggered with high potential, and gate circuit (50) is then triggered with high potential. Gate circuit (40) must be pre-triggered only until the corresponding flipflops are set. Gate circuit (50) does not need to be pre-triggered for as long as possible, but only until the automatic high potential displacement to the right is concluded. <IMAGE>

Patent DE-3926799-A1 (DE)
Inventor: ERNST ALFONS DIPL ING
IPC: G01B21/22
Filed: 1989-08-14
Abstract: An incremental angle encoder of the invention has an encoder shaft connected with a first disk having an incremental angular graduation and a first and a second reference mark. A second disk is connected to this first disk via a reduction gear, on which a spiral-shaped reference scanning field is provided. A first scanning unit scans the incremental angular graduation to generate two scanning signals and the first reference mark to generate a first reference signal. A second scanning unit scans the second reference mark utilizing the spiral-shaped reference scanning field to generate a second reference signal. A specific offset, which indicates the number of revolutions of the encoder shaft, exists between the first reference signal and the second reference signal because of the spiral-shaped reference scanning field. An absolute angular measurement value for the encoder shaft is determined from the scanning signals and from the specific offset for the number of revolutions.

Patent DE-3931638-A1 (DE)
Inventor: HACKBARTH HEIDI DR RER NAT
IPC: G10L15/07
Filed: 1989-09-22
Abstract: A method of this type is intended to be suitable for the recognition of individual words as well as continuous speech. It is to be characterised by robust word pattern recognition in the face of incorrect syllable segmentation and variable diction, e.g. when syllables are slurred. It must also enable fast adaptation of the system to a new speaker and an essentially unlimited generation and extension of the vocabulary from written text without explicit system training through pronunciation. An approximately real-time recognition of words and word sequences should also be possible even with very extensive vocabularies. Known methods of speech recognition require a highly expensive training procedure. Furthermore, an unmanageable flow of hypotheses is generated with continuous speech and a relatively large vocabulary, and even with medium-sized vocabularies. 
<??>According to the invention, the extracted feature vectors are segmented and classified into a set of hypotheses comprising syllable-oriented word sub-units with the aid of a word sub-unit inventory. A word hypothesis set, which is subjected to syntactic analysis in order to identify the spoken phrase, is generated from the hypothesis set by means of a three-dimensional, time-dynamic comparison with diction variants from a reference pattern vocabulary.
