Patent EP-0483997-A2 (EP)
Inventor: CROTTI ALESSANDRO
IPC: B41J29/36
Filed: 1991-10-15
Abstract: An electronic typewriter has a reduced number of electrically-powered actuators and comprises a motor (72) powering a differential motion transmission unit (52) having first and second output members (61, 62). Transmission control means (63) powered by a solenoid (162) moves a slider (146) to engage stop members (128, 129) selectively with the first and second output members to permit the second and first output members respectvely to rotate. The first output member drives the carriage transport mechanism (49). The second output member (62) drives the character carrying element (41) and also powers function devices, namely a correction device (46), through a motion switching mechanism (64) controlled by a switch control mechanism (68) including another solenoid (216). The typing ribbon feed (44) is driven by reciprocation of the slider (146) between its two states. The motor (72) is mounted on the frame (27) and drives the motion transmission unit on a carriage (34) through a belt (78); it also drives a line spacing mechanism (39) through a clutch operated by a further solenoid (339). The motor and solenoids as well as the print hammer (47) are controlled by an electronic controlling arrangement (38). 
     In alternative arrangements the motor (87) is mounted on the carriage (34). A change mechanism (93) controls the output of the motion switching mechanism (64) so that it is applied to the correction device (46) or to the line spacing device (39) depending upon the direction of rotation of the motor. Instead of using a solenoid, the motion switching mechanism is engaged by a friction device (222) driven from the first output member (61) by driving the first output member backwards by one step. The motion switching mechanism is coupled to the line spacing device by a splined bar (32).

Abstract: The present invention is directed to novel 2,5-dichlorophenylthioglycolic acid derivative, a process for their production and a process for producing the desired product 2,5-dichlorophenylthioglycolic acid derived from said novel compounds. 2,5-dichlorophenylthioglycolic acid derivative of the present invention can be obtained by reacting 2,4,5-trichlorobenzensulfonates and thioglycolic acid in the presence of base, and said desired product can be obtained by desulfonating said compound in an aqueous solution of mineral acid. Novel 4-carboxymethylthio-2,5-dichlorobenzenesulfonates of the present invention can be used advantageously as an intermediate for the production of 2,5-dichlorophenylthioglycolic acid. The use of said intermediate makes it possible to obtain the desired product in a decreased process steps with high yield. In addition, it poses no problem of environmental pollution as pointed out with conventional methods because it uses no heavy metals.

Abstract: A description is given of a side termination for metallic exterior window sills. The side termination comprises a side-termination part 1 which is formed as a casing-profile part, open on one side, and has a vertical side wall 2 and horizontal legs 3, 4, 5, of which the upper leg is a covering leg serving as a rendering-protection means and visible surface, and of which the two lower legs together form a chamber 10 which receives the window-sill end. A sprung part 6 effecting a plurality of functions can be inserted into said chamber. The sprung part fixedly clamps the side part 1 when the latter is slid onto the window sill; it ensures, by means of a stop which is configured resiliently in the horizontal direction, that the side part, on mounting, can be pushed onto the window sill only to such an extent that an initially predetermined desired expansion clearance remains reliably intact; and, on insertion, it fixes itself, as a single-piece part, in the receiving chamber of the side-termination part itself. The side termination is of simple structural design, is easy to mount and, even in building-site conditions, can be mounted reliably in the sense that the expansion clearance is reliably ensured. In the installed state, damage due to the change in length of the window sill caused by temperature fluctuations can thus be reliably avoided. The side termination offers, at the same time, an aesthetically pleasing appearance from the front, including the transition between window sill and window-reveal rendering. <IMAGE>

Abstract: The invention relates to a method of manufacturing a replicated magnetic reproduction medium, such as a magnetic-tape cassette provided with a music recording, which reproduction medium comprises a magnetic tape (1) having a plurality of tracks extending parallel to one another in the longitudinal direction at specified spacings within certain limits from one another. The reproduction medium thus manufactured serves for the reproduction of the replicated signals by means of a magnetic reproducing head having a plurality of transducing gaps situated at specified spacings within certain limits from one another. During reproduction a specified normal tape tension within certain limits is sustained, resulting in a normal surface pressure between the tape and the head face of the reproducing head. 
     During replication the tape is moved over a head face of a magnetic replication head also having a plurality of transducing gaps with a certain spacing from one another. 
     During the replication the tension in the tape is increased relative to said normal tension. Another characteristic feature is that, in order to compensate at least partly for deviations in the positions of the tracks which would arise as a result of the increased transverse contraction of the tape caused by the increased tension, the spacings between the centres of the transducing gaps of the replication head are smaller than those of the reproducing head.

Abstract: A method for manufacturing a structural component (100) includes forming a groove (104) in an outer surface of a fibre-reinforced body (102). Molten metal is introduced to an exposed surface of the groove (104) and to a predetermined portion of the outer surface of the body (102). The cast metal (106) is cooled in a controlled manner to thermally alter sufficient resin (103) in the body (102) so as to create a secure interconnection of the cast metal (106) on the body (102). The cast metal (106) adjacent the groove (104) is sized so that it will fail prior to separation of the cast metal (106) from the body (102) under excessive tensile loads. A portion (108A) of the cast metal (106) remains on the body (102) so that elongation of the component significantly exceeds ultimate elongation of the fibre-reinforced body (102) and the cast metal (106).

Abstract: An unknown symbol handwritten on a digitizing tablet is compared with symbols in a predefined "alphabet" or library of model symbols and the closest match chosen, taking into account all or some subset of affine transformations of the unknown symbol with respect to the alphabet symbols. A sequence of samples of the pen position is recorded while a symbol is being written on a digitizing tablet. The samples form a vector, which is then translated so that the centroid of the symbol lies at an origin. The comparison involves finding the minimum "distance" between the vector for the unknown symbol and any vector that can be obtained by linear transformations of the vectors for the model symbols. The model vector for which the minimum such distance can be obtained indicates the alphabet symbol the writer most likely intended to write. Alternative embodiments are described in which the types of linear transformations allowed are restricted.
