Title: Coating method in coating line and coating apparatus therefor
Inventor: MATSUI MASATAKA
IPC: B05D3/02
Filed: 1987-09-22
Abstract: The coating method contains a spraying step in which a paint is sprayed at least on a coating substrate extending in an upward and downward direction to a film thickness thicker than causing sags of the sprayed paint. The coating substrate on which the paint is sprayed is rotated about the horizontal axis while the sprayed paint is dried until it does not sag any more. 
     The coating apparatus includes a carriage conveying the coating substrate arranged to run along the conveying direction, and the carriage is provided with a supporting base for supporting the coating substrate rotatively about the horizontal axis. One embodiment for rotating the substrate supported by the supporting base is a spring that is disposed on the carriage to rotate the substrate by means of a restoring force produced by the spring. On the passage for conveying the carriage is disposed a force storing mechanism for storing the restoring force in the spring that released the restoring force. 
     Another embodiment therefor is a combination of a chain disposed along the conveying passage for the carriage with a sprocket disposed on the carriage. The sprocket is engageable with the chain and operatively coupled to the coating substrate. By disposing the chain in a fixed manner, on the one hand, the substrate is caused to rotate as the carriage is being conveyed. By dividing the chain, on the other, the substrate is caused to rotate while the conveyance of the carriage is suspended.

Abstract: The handle (1) and the bristle bearer (2) of a toothbrush are connected to one another via a hinge (9). The axis (10a, 11a) of rotation of the hinge (9) forms an angle ( alpha ) with the longitudinal axis (1a) of the handle (1). In a first position of the bristle bearer (2), the brush surface (5) extends approximately parallel to the longitudinal axis (1a) of the handle (1). If the bristle bearer (2) is rotated by 180 DEG , the brush surface (5) forms an angle with the longitudinal axis (1a) of the handle (1). The toothbrush can thus be changed over from a position for cleaning the front teeth to a position for cleaning the back teeth. <IMAGE>

Abstract: Un système et un procédé, servant à condenser des données, utilisent un courant de bits en série de données de parole codées et travaillent par lecture des données sous forme de blocs de longueur fixe. Chaque bloc est classifié par un détecteur (46) selon qu'il représente un signal vocal, un signal non vocal ou un silence. Pour un bloc représentant un signal vocal, une période de hauteur du son (IP) est déterminée par un détecteur de hauteur du son (47). Les bits du bloc vocal sont ensuite comparés à une configuration de hauteur du son de référence (RP), afin de détecter toute répétition. Lorsqu'une répétition est détectée, les bits relatifs au nombre de répétitions (N), à la période de hauteur du son (IP) et à la configuration de hauteur du son de référence (RP) sont stockés dans un dispositif de stockage (50) prêt à en effectuer la transmission. On reconstruit ensuite les données condensées en utilisant un décompresseur qui interprète les informations stockées et permet la réinsertion des répétitions.

Abstract: A ring binder mechanism comprises a base member (10) with two or more rings (20,22) mounted thereon at spaced positions along the length thereof. In conventional manner, each ring comprises two separable ring segments which are formed into two opposing sets disposed on opposite lateral sides of the centerline of a base member, each set of ring segments being mounted on a respective one of a pair of blades (19, 19 a ) which are hingedly connected together along the centerline of the base member and at their outer edges engage the lateral margins (14 a , 15 a ) of a front plate (11) which serves as a spring means whereby the blades are driven towards either of two extreme angular positions whereby the sets of ring segments are held either in the open or closed positions. The front plate (11), instead of being of smoothly arched shape as is conventional, is of shallow V-shape in transverse section and presents two flat faces (14, 15) which conform as closely as possible to the apex formed by the blades when the ring segments are in their open position.

Abstract: To support a long spindle with a spindle nut thereon, a plurality of support elements are located in a housing (1), the support elements (26, 226) including spring-biassed sliders which, when positioned at predetermined stop recesses (48) in the inside of the housing (1) engage the stop recesses. Upon movement of the spindle against a support element (26, 226), the spring-biased sliders are pushed out of the recesses and the lifting movement of the sliders engages a projecting connecting dog (44, 53) in the groove of a take-up carrier rail, the groove being closed off at the end. As the spindle nut (5) moves, support elements (26) are pushed ahead of the leading face thereof, with respect to the movement of the spindle nut, and collected. Upon reversal of movement of the spindle (4), the end stop (51) of the take-up carrier rails pulls the support elements (26, 226) along until a support element snaps into a stop recess (48), thus releasing the connecting dog (44, 53) from the groove (50) in the rail, and permitting the end stop (51) of the carrier rail to pass over the connecting dog, thereby positioning the respective support element at the location of the stop recess.

Abstract: The present invention therefore is concerned with a process for the extraction of lactones from a lactone-­containing lipid material, by contacting a medium, having a temperature near the critical temperature of said medium, and having a pressure near the critical pressure of said medium, with the lipid material, and subsequently removing the medium, wherein the medium, upon contacting, has a temperature T (in °C), and pressure P (in bar), such that: 
-25 <=T* <= 18.5 
-40 <= p*<= 300 
T*xP* <=1900 
where T* = T-T c , P* = P-P c , T c  is the critical temperature (in °C), and P c  is the critical pressure (in bar) of said medium. 
Under the extraction conditions as applied in the process according to the present invention a low yield, combined with a high selectivity is obtained, resulting in a relatively small extracted fraction, which is substantially enriched in lactones. 
     Another aspect of the present invention is the use of an extract obtained by the process according to the present invention for flavouring foodstuffs.
