Patent CH-627319-A5 (CH)
Title: Method for operating a telecommunications switching system, in particular a telephone switching system
Inventor: ZWICKY ROBERT
IPC: H04Q3/42
Filed: 1978-04-11
Abstract: The method relates to a telecommunications switching system, in particular a telephone switching system, to which subscriber stations with different dialling types, such as pulse dialling (IW) and audio-frequency push-button dialling (TWm, TWo), are connected. Each change of condition in a subscriber line loop of a subscriber station with a call in progress is evaluated and the dialling type of the subscriber station concerned or a switching signal (ET, FT) transmitted by it is determined therefrom. The determined dialling type is in each case recorded in a memory (TDSP), the contents of which are used in every assessment of a change in loop condition. In a switching system operated according to this method, subscriber stations with any given dialling type can be connected to any given subscriber terminal and can be interchanged virtually without restriction; the switching system is able to identify an interchange of this type as soon as the subscriber has dialled a digit following an interchange in its subscriber station. <IMAGE>

Title: Instrument for performing music
Inventor: CAPPER LAURENCE CLAUDE
IPC: G10G1/00
Filed: 1979-06-01
Abstract: The keyboard (14) has a front row of keys (16) and a back row of keys (17), which are each allocated to a sequence of whole tones which in turn are mutually offset by half a tone. The keys (17) of the back rows are in each case arranged between two keys (16) of the front row. The musical notation suitable for use with a keyboard (14) has note lines (13) arranged in pairs. The distance between adjacent pairs of lines is twice the distance between the lines of a pair. The musical notation also has two types of notes (11, 12) which differ from one another in the colouring in relation to the note lines (16, 17). The colouring marks in each case one of the key rows. The first and third keys (16G and 16B) of each octave on one of the key rows differ from all the other keys (16, 17). Notes of the colouring allocated to one key row, which are on one or the other line of a pair of the note lines, correspond to these different keys. This instrument facilitates the performance of music on sight. <IMAGE>

Title: Method for the run-through measurement of textile threads in textile machines and apparatus for carrying it out
Inventor: HAENI ALBIN
IPC: D04B15/48
Filed: 1981-08-31
Abstract: The method provides an indirect run-through measurement of the entering thread (4), either on a feedwheel (6) or on the drive belt (10) of the latter. A variable proportional to the thread quantity running through can be picked up at the points 13a, b or c, as a result of which the thread (4) is not touched on its path from a yarn bobbin (5) to the knitting point (7). The measured variable can be related electronically to the number of revolutions of the rotor (1a) determined simultaneously by a master/slave pair (3), and the values of the thread quantity per revolution thus determined can either be displayed directly or be used for monitoring the machine. <IMAGE>

Title: Apparatus for the optoelectronic monitoring of an individual roving between the drafting unit and spindle of a flyer
Inventor: WITSCHI HANS
IPC: D01H13/16
Filed: 1982-12-09
Abstract: In order to overcome the disadvantages of the known apparatuses of this type transporting broken rovings (8) to a checking and switch-off unit by means of a suction device, there is proposed an apparatus in which a plurality of individual reflex sensing heads (7) can be mounted exchangeably at a distance from one another on a fastening rail (13) by means of springs (4) in a housing (2) elongated in a channel-like manner. Each reflex sensing head (7) contains at least two infrared emitters (5) and a photocell (6) which detects the radiation reflected by the roving (8) running above the housing (2) closed by means of a glass plate (3). If such reflected infrared radiation is absent, the reflex sensing head (7) switches the flyer off automatically via a switching amplifier. Because this monitoring apparatus is arranged directly after the drafting unit (9) in the running direction of the roving (8), it detects any absence of a roving (8) at the exit of the drafting unit (9), as a result of which damage to the machine, caused by rovings pouring freely into it, can be avoided. The apparatus according to the invention increases the productivity of a machine very greatly and ensures that the latter is not stopped needlessly. However, it also guarantees that the flyer is stopped whenever a roving is absent at the exit of the drafting unit (9). <IMAGE>
