Abstract: In a conching device (1) at least one rotor (2, or 3, respectively) is driven by an electric motor (9). The driving motor (9) is controlled by means of a motor control unit (8). To establish the amount of energy introduced into the conching device (1), at least one motor-operation parameter is detected and evaluated. To shorten the conching time of a conching process to the necessary extent, it is provided to establish the amount of energy introduced into the conching device at least during the viscous-plastic phase of the chocolate mass and to control the conching process in dependency upon the summation value of energy attained. Since the amount of energy introduced during the viscous-plastic phase determines the properties and the quality of the chocolate, a high reproducibility will be ensured.

Abstract: A method of and apparatus for eliminating waste of dry film solder mask material in an existing solder mask vacuum laminator (10A) in which dry film being laminated to printed circuit boards also spaces the boards from each other and serves as an interconnection therebetween comprises modification of the laminator to adapt it for use in the vacuum lamination of boards to the surfaces of which dry film already has been loosely applied by tacking of the film to the leading and trailing edges of each board. The existing device is modified by substituting a reel (56) of carrier film (58) for that one of the dry film supply reels that supplies dry film beneath the boards to be laminated. Additionally, an automatic rewind or takeup unit (60) for the carrier web is provided at the discharge end of the laminator. The original machine shafts for the supply reels of dry film are retained for use with the supply reel for the carrier film and for the rewind unit. All other machine functions are retained.

Title: Apparatus for controlling open/close drive of a lid for a recording medium player
Inventor: ODASHIMA MASAHIRO
IPC: G11B33/02
Filed: 1991-05-21
Abstract: A driving apparatus for opening and closing a lid (1) which is provided to open or close a recorded medium insertion opening of a recording medium player. When the lid does not reach a fully opened position or a fully closed position in a predetermined period of time after the starting of opening or closing drive of the lid, such a fault condition can be removed by inverting the direction of rotation of a driving motor (3). Moreover, the lid is driven in the closing direction after a predetermined period of time from the time when a recording medium is inserted into the recording medium insertion opening, or the lid is driven in the closing direction in response to a closing command. By these operations, it is made possible to prevent the lid from being left in a halfway closed position.

Abstract: The invention relates to a process for the preparation of a conjugated diene from the corresponding carbonyl compound having the same number of carbon atoms by dehydration at a temperature of 300° to 450°C using a catalyst comprising aluminium phosphate having the cristobalite structure. 
     This catalyst is superior to aluminium phosphate having the tridymite structure in the dehydration of carbonyl compounds and has advantages over boron phosphate catalysts. Using the process, isoprene may be prepared from 2-methyl butanal and/or methyl isopropyl ketone in high yields. 
     Unexpectedly aluminium phosphate having the cristobalite structure is markedly superior to boron phosphate in converting methyl isopropyl ketone, which is an intermediate product formed in appreciable amounts in the dehydration of 2-methyl butanal to isoprene. This superiority significantly improves the process economics of the conversion reaction of 2-methyl butanal to isoprene.

Abstract: An ultrasonic transesophageal scanhead is provided which enables a physician to easily and quickly change the orientation of the image plane during a scanning procedure without disrupting control of the scanhead. Means (36) are provided on the external control unit (16) of the scanhead for unambiguously selecting the orientation of the plane which is imaged by the transducers (E1L..E48T) at the end of the probe (12) of the scanhead. In one embodiment, a rocker switch (36) is provided on the underside of the control unit, and a lighted indicator (40) is provided on top of the control unit. When the physician desires to change the image plane, the rocker switch is rolled forward to select the transducer elements (E1L..E48L; E1T..E48T) of the probe which are configured for scanning in the desired image plane. As the rocker switch is moved, the lighted indicator (40) on the top of the control unit provides a visual display pattern aligned either longitudinally (40b, 40c) or transversely (40a, 40b) with respect to the axis of the probe. Thus, the physician can change scanning planes without moving his hand from the control unit, and the unit constantly provides an indication of the orientation of the selected plane.
