Abstract: An abrasion evaluation test method applicable to a case where a rotating disk and a friction member to be brought into slide contact with the disk contact and abrade each other even while a brake is not applied due to vibrations and mounting errors. The disk is an actual disk and the friction member is a test piece which is smaller than the actual friction member. The test piece is pressed against part in a radial direction of a frictional surface of the disk at a predetermined position. The abrasion of the disk is measured with respect to a portion of the frictional surface that is out of contact with the test piece, while the abrasion of the friction member is obtained from the difference in thickness of the test piece before and after testing.

Abstract: The invention prevents a tone arm's unnecessary vibration caused by vibrations of a cantilever to allow the cantilever to vibrate precisely following wave shapes in sound grooves of records, thereby faithfully reproducing phonic information recorded in the records. 
     The invention provides a standing damping bar on the cantilever directly thereto or through other parts to change upward or downward vibration of the cantilever to the damping bar's modified vibration directed in a direction extending to or away from the tone arm spindle and cause the modified vibration to be damped forward or rearward in that direction, thereby causing the cantilever to be subjected to reaction force from the tone arm spindle.

Abstract: The invention relates to a holder for winding overhangs of coils in electrical machines, by means of a cable tie (13) as a result of which loose wires are prevented from being set in oscillation. This cable tie (13) has been prevented from sliding on the winding overhangs (11, 41, 43) by impregnation of the cable tie (13), which necessitates an additional operation. This is prevented according to the invention in that the cable tie (13) has an injection-moulded blocking web (27). This blocking web (27) is wedged in the window (29) between the end surface (31) of the stator laminate stack (3) and that of the winding overhang (41, 43, 11), when the cable tie (13) is tightened. In consequence, the cable tie (13) is always reliably prevented from sliding out sideways. <IMAGE>

Abstract: In accordance with Fig. 3, a locking device for the selection lever (1) of an automatic gear locks the selection lever (1) in the neutral positions P and N by positive engagement of a locking member (19), fixed to the selection lever, in recesses (4, 5) of a pivotable pawl (3). An actuating force (FB) acting on the selection lever (1) in the locked condition is introduced into steep flanks (22, 23) bounding the recesses (4, 5), at a point (E) of contact, via curved contact faces (20, 21) of the locking member (19). A small supporting force (FV) resulting from this imposes a slight load on two rollers (6, 9) which support the pawl (3), making it easy for one roller (9) to be displaced by means of a solenoid actuator (14) into a position (S1) in which it releases the pawl (3) and unlocks the selection lever (1) despite the action of the actuating force (FB). <IMAGE>

Abstract: A device (1) for photoelectrically sensing the color of an object (18) includes a plurality of light emitting diodes (4, 6, 8) emitting light in a narrow range of wavelengths and where the light is transmitted through a corresponding fiber optic bundle (10, 12, 14) with a diameter in proportion to the transmission loss of the bundle and in inverse proportion to the emitted light energy of the corresponding light emitting diode and in proportion to the spectral response of a receiving photodiode (24). A receiving section (22) utilizes a PIN type photodiode (24) with an input section (40) that matches the shape of a receiving optical fiber bundle termination (42) where the photodiode (24) converts the reflected light from the object (18) into electrical signals which are then processed by a microprocessor (28) which also controls the activation of the light emitting diodes (4, 6, 8) and outputs a signal indicative of the color of the object (18).

Abstract: A laminate containing at least one melded binder-consolidated nonwoven based on carrier fibres and binding fibres and a fabric bonded thereto, which is bonded to the nonwoven by means of an adhesive layer. The laminate is characterised in that said adhesive layer is obtainable by virtually complete fusion of binding fibres, which are located in the form of a layer at least on the surface of the nonwoven which faces the fabric. The laminate according to the invention can be used for the production of bituminised roofing and sealing webs. Melded binder-consolidated nonwovens based on carrier fibres and binding fibres are also described in which these nonwovens have layers differing from one another, in which mainly said carrier fibres or mainly said binding fibres occur. These nonwovens are characterised in that they have at least three of these layers and in that at least one surface of the nonwoven is formed by a layer mainly containing binding fibres, which is partially fused. A process for the production of the laminate according to the invention is also described which comprises the following steps:   i) production of a spun-bonded nonwoven by spinning of molten polymer material from series of spinnerets arranged parallel to one another with the formation of carrier fibres and binding fibres, where at least the first and/or the last series of spinnerets is coated with polymer material suitable for the production of binding fibres, ii) stretching and laying of the polymer streams thus obtained on a conveyor belt in a manner known per se, such that a layer consisting mainly of binding fibres is formed at least on the top or on the bottom of the primary nonwoven formed, iii) mechanical stabilisation of the primary nonwoven located on the conveyor belt by the use of pressure and/or of elevated temperature on said primary nonwoven, such that this can be handled without damage in the following step, iv) intermediate consolidation of the stabilised primary nonwoven by calendering and fusion of a part of the binding fibres, v) addition of a fabric such that said fabric is combined with said intermediately consolidated spun-bonded nonwoven such that the surface of the spun-bonded nonwoven which is formed mainly of binding fibres comes into contact with the fabric, and vi) exertion of elevated temperature and, if desired, elevated pressure such that the binding fibres are fused virtually completely to the contact surface between spun-bonded nonwoven and fabric, an adhesive layer between both fabrics is formed and the laminate undergoes final consolidation.   <IMAGE>

Abstract: A barrier system which comprises a plurality of horizontal layers (9,10,12) and is laterally bounded by vertical walls (8) of the building is constructed between the ground (1) and the interior (4) of the building. The intention of this is to protect the entire building or parts thereof against the entry of dangerous gases by convection and/or diffusion, the barrier system being arranged above the dividing line between ground and building. At the same time, the entry of gases from the building into the ground is to be prevented. According to the invention, this takes place by air being introduced into an intermediate layer (12), lying between the layers (9,10) inhibiting the passage of air and gases, and by an air pressure which is different from the ambient pressure being built up, the air which is introduced flowing through the intermediate layer and leaving it again, thereby removing from the building harmful gases which have entered into this intermediate layer. <IMAGE>

Abstract: A vector codebook with an ordered set of vector entries that satisfy a prearranged continuity requirement is used to encode signals. The continuity requirement specifies that consecutively considered vectors may not differ from each other by more than k elements, where k is less than the number of elements in the vectors. In one embodiment, two memories are maintained. One for determining the best codebook vector selection, and one for quantizing the input signal in accordance with the selected vector. Recognizing the possibility that the best ordering possible for a given set of codebook vectors can not satisfy the continuity requirement, the vector codebook arrangement of this invention is enlarged in such a case to include additional vectors that are interposed in the sequence of vectors and arranged to maintain the continuity requirement.
