Abstract: A tone generating apparatus comprises at least an address generator (20, 22 and 24), a waveform memory (10, 14) and a sound system (38, 40). The waveform memory provides a plurality of storing areas (12) each of which stores word data of N bits. Amplitude data of M bits (where M denotes as N < M ≦ 1.5N) of two sampling points are pre-stored in three storing areas in order to raise the utility efficiency of the waveform memory. Then, the word data stored in each storing area are sequentially read out from the waveform memory in a predetermined order based on the addresses generated by the address generator, and the amplitude data of two sampling points are reproduced by use of three word data stored in three storing areas. As a result, the tone corresponding to the reproduced amplitude data is generated in the sound system (38, 40).

Abstract: The gear transmission has a meshing geometry with the following parameters: contact ratio greater than one, height (h g ) of addendum (1) of pinion (2) being a func­tion of its module "m" determined by the following re­lationship: m < h g  < 1.8 m, height (h s ) of tooth root (1) of the pinion (2) being limited by the value of pro­file angle (α z ), equal to: α z  ≧ 8°, height (H s ) of tooth root (5) of the gear wheel (6) determined by the rela­tionship m < H s  < 1.8 m increased by the value of the radial clearance (l p ), whereas the height (H g ) of the addendum (5) of the gear wheel (6) is equal to the height of the root (h s ) of the tooth (1) of the pinion (2) de­creased by the value of the radial clearance (l p ). 
     Such a variable pressure angle in a gear transmission with cylindrical gear wheels, with straight and oblique teeth, as well as in worm gears leads in effect to a con­siderable reduction of contact stresses which are seve­ral or ten times smaller, to reduced tooth slips, and to the more favourable lubricating conditions.

Abstract: The production of the internal thread of a connection sleeve (4), which is used as a coupling element for parts of a rock support or of a drill rod, by machine-forming, in particular by thread-cutting, entails great effort since, in the round thread used here, a considerable amount of machining work is required. Furthermore, it is disadvantageous in this application in the machining of the thread that the long-term strength of the connection sleeve is considerably impaired due to the notch effect in the base region of the thread turns. A connection sleeve and a method for its production are proposed, in which the internal thread is produced without machining by shaping the outside of the connection sleeve (4) in the manner of a thread so that the image of this shaping forms the internal thread to be produced on the inside. Apart from the increase in strength caused by the non-cutting shaping, which is usually cold shaping, due to material reinforcement, the further advantage results that the shaping required here can be applied in a single operation so that the production costs of connection sleeves (4) of this type can be reduced. Furthermore, it is advantageous that the external thread, interacting with the internal thread of the connection sleeve, of the components to be connected to one another can have a basic shape which corresponds to the outside thread-type shaping of the connection sleeve (4). <IMAGE>

Abstract: A video noise reduction circuit for use in a video signal recording apparatus records red, blue and green primary colour component video signals on a plurality of separate tracks of a magnetic recording medium. The component video signals are supplied to a matrix circuit (2) which produces a wide-band luminance signal. A band splitter circuit (10) splits the wide-band luminance signal into an upper-band luminance signal and a lower-band luminance signal, and an expansion circuit (14) expands the low level components of the upper-band luminance signal before the upper-band luminance signal is frequency modulated. Since the expansion circuit (14) follows the band splitter circuit (10) having a flat phase versus frequency characteristic, the video noise reduction circuit can reduce video noise without causing distortion of the frequency modulated video signal.

Abstract: A surgical clip of plastics material for performing sexual sterilization comprises two jaws 12,14 hinged to move from an open position to the closed position shown, in which a Fallopian tube 18 is occluded. A catch mechanism 20 engages when the jaws reach their closed position, and locks the jaws closed. The location of the catch mechanism 20 in the vicinity of the hinge 16 ensures that it does not contact the vulnerable mesosalpinx 58, thus reducing the risk of bleeding. Interdigitated teeth 26,36 and a curved, springy tongue 54 prevent the tube 18 escaping from the clip as the jaws close. The teeth are rounded and are loosely interdigitated to reduce the risk of damage to the mesosalpinx 58. A resilient lining 22 on the jaw biasses them apart. The clip will spring back open during application if it has not been closed sufficiently to engage the catch mechanism. The biassing also enables the clip to be located firmly in an applicator before closure.

Abstract: A method and system for radio communication between at least one parent communication unit and a plurality of slave communication units. A slave communication unit transmits an automatic answer signal in response to an incomming call receipt signal transmitted from the parent communication unit. When one of the slave communication units makes a called-person's answer to the incomming call receipt signal, it transmits a called-person's answer signal. If interference occurs between the automatic and called-person's answer signals, the parent communication unit provides a command, causing the slave communication units to stop the automatic and called-person's answer signals and permits the slave communication unit which transmits the called-person's answer signal to communicate with the parent communication unit.

Abstract: Apparatus for shear wave borehole logging has a source section 30, a spacer section 32, a detector section 34 and a coupling section 36, adjacent sections being linked by isolation joints 38. The source section 30 has a slotted steel housing 48 containing a source 42 with two transducers 44 a /44 b  and 44 c /44 d  each arranged to produce acoustic radiation with a dipole radiation pattern. The transducers are oriented so that their radiation patterns are transverse to one another and to the borehole axis. The detector section 34 also has a slotted steel housing 80 and contains six detectors 82 each with two transducers 84 a /84 b  and 84 c /84 d  arranged similarly to the source transducers. The isolation joint 38 between adjacent sections comprises lengths of steel wire 76 secured at each end to one of the sonde sections and bridging a gap between the sections. In use each of the source transducers is energized in turn as the apparatus is drawn up the borehole, and the waveforms of signals received by the twelve detector transducers are digitized and recorded. Various analyses of the recordings enable the formation shear slowness to be derived, even in 'slow' formations, and permit information to be obtained regarding the magnitude and orientation of anisotropy in the formation.

Abstract: A gas turbine engine control system operates based upon a synthesized value of a parameter upon loss of the actual measured value of the parameter. To provide smooth engine operation upon switchover to the synthesized parameter a fixed trim is applied to the synthesized parameter which, upon switchover, makes the synthesized parameter equal to the last known measured value of the parameter. Thus, the engine will see no sudden change in operation at the instant of switchover. Thereafter the trimmed synthesized parameter changes in value by the same amount as does the untrimmed synthesized parameter.

Abstract: Foldable money bags, such as are used by waiters and waitresses, have several adjacent compartments for bank notes and a coin compartment which can be opened out and is larger compared to said former compartments. For giving change in coins, the coin compartment is shaken so that as many coins as possible lie adjacently and are individually recognisable. This is difficult when there is insufficient or no lighting, e.g. in candlelight. It is therefore proposed to design the coin compartment (5) so as to be illuminated by at least one bulb (12). <IMAGE>
