Title: Audible tone generation in PCM telephone exchange - storing operative frequencies as digital bit code in memory
Inventor: RAMBOLD THOMAS DIPL ING
IPC: H04M1/50
Filed: 1980-09-26
Abstract: The proposed tone signal system uses the power and memory of a microprocessor to reproduce the tones on demand without having to switch in an analog signal generator. The analog signal representing the typically multifrequency tone is generated in an oscillator (SWE). A converter (C) controlled by a clock or pulse generator (TG) changes this signal into a bit pattern by a sampling method. The same clock also enters this now digital signal into a memory (Sp) to a set time pattern. The memory forms part of a microprocessor. The time divisions are spaced at typically 125 microseconds. By reading out the stored information the desired tone can be synthesised. Inside the time interval several different tones can be stored, and by selecting the read out the processor can be ordered to reproduce the desired tone. The system may be realised using a single chip processor.

Title: Winning-machine guide with sealing strip for fines
Inventor: RAFAEL WERNER
IPC: E21F13/06
Filed: 1981-10-01
Abstract: The invention relates to a winning-machine guide with a winning machine which can move along a working face and is positively guided on a guide which is arranged on the conveyor side section of a scraper chain conveyor and on which a flexibly mounted fines barrier is arranged. In underground winning systems, it is necessary to keep the support area free from excavated material, in particular fines. This is achieved according to the invention by the fines barrier having sealing strips sliding more or less vertically, the bottom free end edge of which bears against the floor and thus prevents the ingress of fines into the support area. A fines barrier of this type can be arranged on both the working face side and the goaf side of a scraper chain conveyor.

Title: Method of processing biomasses and equipment for carrying out the method
Inventor: LINNEBORN HANS DIPL ING
IPC: C10B53/02
Filed: 1981-11-12
Abstract: The invention relates to a method and to equipment for carrying out the method, which have the object of producing high-grade end products, such as charcoal, pyrolysis gas or synthesis gas, from so-called biomasses. The starting point for this purpose is the known pyrolysis process which, according to the invention, effects frequent contact of the processing particles having a maximum size of 20 mm in a fluidised bed generated by means of air, purging gas or steam. The pyrolysis gas formed can be taken off wholly or partially, like also the charcoal, from this stage of the method. If the pyrolysis gas is fed in the course of ascending gasification to a fluid bed, the valuable synthesis gas is produced. The equipment for carrying out the method contains, in a tower-like structure, two superposed gratings and outlets for charcoal, for feeding charcoal for the fluid bed, heating zones for providing cracking temperatures, feeders for air and/or steam and outlets for gases.

Title: Cutting device for cutting web material into pieces
Inventor: COLLINS KEITH THOMAS
IPC: B26D1/60
Filed: 1982-09-28
Abstract: A cutting device for cutting web material into pieces comprises a pair of drive rollers (1, 2), a slide (4, 5), movable forwards and backwards and carrying a guillotine (10-13) with movable cutting knife (11), and a four-link system (21-26) for controlling the movements of the slide and the cutting knife. The end (25D), connected to the slide, of one of the three levers of the four-link system describes an elliptical orbit whose region located underneath the longitudinal axis of the ellipse is passed through in the forward direction; transmission means (15-19) on the slide (4, 5) transmit the movement of the lever end (25D) to the cross-section of the cutting edge of the cutting knife (11) in such a way that the said cross-section describes an orbit homologous to the abovementioned orbit; the web (B) forms, through the lower region of the homologous orbit, a chord which is traversed by the cutting edge cross-section downwards in the end region, at the back in the direction of movement of the web, of the orbit and oppositely in the forward-located end region. Control means ensure that the speed of the forward movement of the slide (11) in the lower region of the homologous orbit is equal to the web speed, whereas the slide speed can, in the case of backward movement, be equally fast, faster or slower. <IMAGE>

Title: Bicycle hub with two free wheels
Inventor: DROESCHEL HELMUT
IPC: B62M11/18
Filed: 1983-03-18
Abstract: Bicycle hub with two blocks (17, 20) which can be displaced separately in an axial direction. The small right-hand block (17) has the two positions I, II and a two-stage planetary gear P2. The large left-hand block (20) has the three positions or groups H, M, L and a three-stage planetary gear P3 with free wheels FM and FHL with catches (23, 24). In this way, 6 speeds are obtained. The large planetary gear P3 produces at L a large transformation ratio, at H it operates as a branch. Therefore, there are large increments S between the speeds at the bottom but small ones at the top. In the central group M, the more rapid rotation of the large sun wheel (56) at position II brings about an overall step-down transformation i. Therefore, the sequence I/II is reversed at M. As a result, the double change which is otherwise necessary with other group gears is dispensed with. Therefore, when changing gear either the small block (17) is moved exclusively for 1/2 = I/II, 3/4 = II/I and 5/6 = I/II; or for 2/3 = L/M and 4/5 = M/H, the large block (20) is moved exclusively. In the case of the axial movement of the latter (20), the latches (23, 24) of the two free wheels FM and FHL are simultaneously changed. The large annular wheel (21) of P3 drives the hub sheath (7) of the rear wheel via the one free wheel FM in group M whilst, however, in group H or L the large planetary carrier (22) of P3 drives the hub sheath (7) via the other free wheel FHL. The manual gear change is effected continuously with a single gear-shift lever (12) which ... Original abstract incomplete. <IMAGE>
