Patent EP-0257819-A2 (EP)
Inventor: BIDNER HARVEY
IPC: G02B26/12
Filed: 1987-07-29
Abstract: A laser scanning apparatus is provided with a compensating arrangement whereby deviations of a synchronous drive are compensated for by adjusting the frequency with which the laser beam is modulated. The laser beam is directed onto a rotatable spinner (10) which causes the laser beam to scan a synchronized moving medium in a number of sequential and parallel lines, each of which is determined during a cycle of the movement of the spinner. The spinner is driven by a synchronous motor. During each cycle, a period error is measured to determine a compensating signal which is held for the next successive cycle and is used to control the frequency of a variable oscillator (62) which determines the clocking rate at which information is employed to modulate the laser beam. According to the method of the invention, lines of information are placed on a synchronized moving medium responsive to the aforesaid laser beam during successive cycles. The method involves modulating the laser beam in accordance with the information and at a frequency which is modified for each cycle in accordance with the deviation of the preceding cycle with respect to a characteristic normal time period.

IPC: A61F13/20
Filed: 1987-09-15
Abstract: An apparatus for continuously and rapidly forming petal-like segments at the tip of a tampon inserter (A) into a hemispherically curved shape. Sets of molds (7, 8) are mounted on a support table (5) on a rotaray table turned about a shaft (2). Each set comprises a heating mold (7) to heat and soften the tip of the tampon inserter and a cooling mold (8) to shape while being cooled the heated and softened tip. The heating and cooling molds are moved by a cam (21) so that either of the two molds is placed above the tampon inserter held in position by a gripper. The gripper (25) comprises a pair of gripper segments that are opened and closed by a cam (36) on the shaft and raised and lowered by another cam (36) on the same shaft. The cams are adapted to release the tampon inserter (A) from the gripper (25) after the tampon inserter (A) has been put first in the heating mold (7) and then in the cooling mold (8). The tip of the tampon inserter held by the gripper first enters the heating mold (7) to get heated. While the heated tip descends temporarily, the cooling mold (8) is brought to above the tampon inserter (A). As the tampon inserter (A) rises again, its tip comes in contact with the inner surface of the cooling mold (8), in which the tip is formed into a hemispherically curved shape while being cooled.

Abstract: The invention relates to a closure assembly for a container. 
     The closure assembly comprises a first cap portion (11) hingedly connected to a second cap portion (12) adapted to be positioned over the mouth of an associated container and including an aperture to permit dispensing from the container. The first cap portion is arranged so that in one position it overlies the aperture to close the container, and in another position is lifted clear of the aperture to open the container. The cap portions together include means so that they can be snapped together and their separation from a closed to an open position requires the exertion of a positive force by the user and the first cap portion includes at its periphery opposite its hinged connection with the second cap portion a lip (22) which co-operates with an inwardly displaceable section (42) of the second cap portion. The inwardly displaceable section includes at its upper edge face adjacent the lip a portion which is associated with an outermost lower edge of the lip when the two cap portions are in a closed position and raised above that lower lip edge so that on inward displacement of the said section the raised portion first offers resistance to displacement in its engagement with the lip edge and then, as displacement pressure is increased, forces the lip upwards. In that manner the snap action of the two cap portions can be overcome and the closure opened.

Abstract: Passive loudspeaker boxes with change-over switches on individual cross-over network branches, in most cases in the medium-range and/or high-range branch, are known. They allow levels to be matched to the room acoustics and/or equalisations in accordance with taste. Boxes which are driven by active networks which contain additional passive permanently installed cross-over networks and thus provide the possibility for "passive operation" are also known. The invention was based on the object of equipping a frequency cross-over network of a loudspeaker box in such a manner that the overall characteristic of the loudspeaker box can be changed to adapt it to different market conventions and/or to the tastes of individual customers. The solution provides that the cross-over network is constructed as a multiple-frequency cross-over network, all of the different cross- over network branches of which can be optionally alternatively connected to the range loudspeakers (TT, MHT) by means of a centrally controlled multi-pole change-over switch (S), in which arrangement in each case two corresponding change-over contacts are provided for each cross-over network branch at two different switch levels (A, B) and these are alternately closed in pairs.

Abstract: In known glass fibre transmission systems with a plurality of stations, each station has a transmitting device in which the incoming signal is amplified before being forwarded. In the event of station failure, the energy of the refreshed signal supplied via a branching element is absent, with the result that, if failure occurs in a plurality of successive stations, the optical signal is excessively attenuated. Two glass fibre transmission lines are provided, operating in opposite directions, and a transmitting device controlled by a time frame generator is connected at one end, wherein the free time slots are provided with a continuous optical signal which can be modulated by the transmitter of a station. Both glass fibre transmission lines are used to transmit information. The glass fibre transmission system enables secure transmission of data between stations, ensuring reliable operation even in the event of interruption in the glass fibre transmission line. <IMAGE>
