Patent EP-0428805-A1 (EP)
Inventor: HAGEMAN MARTIN P
IPC: B65G69/28
Filed: 1989-11-23
Abstract: The holddown mechanism (14) includes a cylinder (15) connected to the ramp and a piston (16) is slidable within the cylinder and carries a tubular piston rod (17) which is connected to the frame (4). The piston is provided with a longitudinal passage (20) which is closed off by a valve member (21), and an actuating rod (22) is connected to the valve member and extends outwardly through the piston rod with the pro­jecting end of the valve member being connected to a lever mechanism (28). The cylinder contains a hydraulic fluid such as oil, and the piston is normally locked in position in the cylinder so that the ramp is locked against movement relative to the frame. By manual operation of the lever mechanism, the actuating rod can be raised relative to the piston to open the valve member, thereby permitting fluid to flow from one end of the cylinder to the other to enable the ramp to be raised under the influence of the counterbalancing spring. Release of the lever mechanism will close the valve and hold the ramp in a given position. As an operator walks outwardly on the ramp, the added weight overcomes the counterbalancing force moving the ramp and cylinder downwardly relative to the actuating rod to open the valve member and permit the ramp to be freely lowered. A coil spring (40) interconnects the ramp and the cylinder to permit the cylinder to follow upward float of the ramp when the piston is in a locked condition.

Abstract: A mechanically controlled writing instrument with pre-sharpened writing elements (30) comprises an inner cylinder (20) and a housing (10). The inner cylinder (20) is a straight hollow tube, having two elongate longitudinal grooves (23,24) at the bottom end to permit the bottom end to be expanded slightly for the passage therethrough of the writing elements (30). A plurality of wedge-like projections (28) are squeezed inwards by the inner wall surface of the outer housing (10) to retain the bottom writing element (30) firmly for smooth writing. The housing (10) has a reduced diameter bottom end (15) having a hook (12,13) integral therewith for alternative insertion through the two grooves (23,24) into the inner cylinder (20). The hook (12,13) is controlled for outward displacement by a lever motion effect. When the inner cylinder (20) is pressed down, the hook (13) is pushed aside to permit the bottom writing element (30) to pass beyond the hook, with the said bottom writing element being stopped by the hook so as to protrude partly out of the outlet (29) for writing purposes when the inner cylinder (20) is returned to its upper limit position.

Abstract: A stabilizing bath which provides reduced stain and enhanced dye stability for photographic color elements which are processed therein is comprised of a dye stabilizing agent, an alkanolamine, and a hydrolyzed polymaleic anhydride or water-soluble salt thereof. The stabilizing bath is used as a final processing bath which follows treatment of the element in a fixing or bleach-fixing bath containing a thiosulfate fixing agent. The alkanolamine functions to prevent the precipitation of sulfur resulting from carryover of the thiosulfate fixing agent into the stabilizing bath, while the hydrolyzed polymaleic anhydride or water-soluble salt thereof functions to avoid the formation of unwanted precipitates.

Abstract: Use is made of two A/D conversion systems of low accuracy to obtain digital output signals maintaining higher conversion accuracy than that of only one A/D conversion. By using two D/A conversion systems of low accuracy, furthermore, analog output signals are obtained maintaining higher conversion accuracy than that of only one D/A conversion system. Provision is further made of digital signal clock conversion means for forming second digital data in synchronism with second clocks by the interpolation processing based on the data obtained by highly sampling first digital data series and a difference between the first clock timing and the second clock timing. Using two PCM.CODEC's (54,55) and one DSP which are cheap and small in size, A/D and D/A conversions are realized maintaining high accuracy. Therefore, the signal processing that was so far carried out using a large-scale analog circuit is now carried out easily using one DSP. In this case, furthermore, the digital signal clock conversion means is realized in the same DSP as the digital signal processing.

Abstract: A closure, fitted with a U-shaped profiled base, for containers is to be further developed in such a way that the seat and seal of the closure are not impeded even in the case of deformations of the pipe attachment of the container, holding the closure and surrounding the filling opening, and in the case of excess pressure prevailing in the container. For this purpose, the outer pipe attachment 11, gripping over the pipe attachment of the container, of the base 1 of the closure is additionally tightly enclosed by a tubular region 13 of an L-shaped profiled ring 12, the annular region 14 of which lies on the outer covering surface of the base 1 and is expediently connected to the latter. Additionally, the inner pipe connector 10 of the base 1, engaging in the pipe attachment of the container, can be supported by a supporting ring 24 which is introduced into said pipe connector and whose axial position is expediently secured, when it has been inserted from below, by holding elements 25 which hold it with positive fit or grip behind it. <IMAGE>

Abstract: A magnetic armature controlled servo valve, activated by its own medium, having a differential piston (2) which supports the valve plate (3) and on whose one side there is arranged a surge chamber (5) which is connected to the valve inlet (Z) and can be connected via the valve seat (4) to the valve outlet (A) and on whose other side there is arranged a control chamber (6) which is connected via a relief hole (2.1), arranged in the differential piston, to the valve outlet (A) and via a control hole (2.2) to the surge chamber (5). The relief hole (2.1) is closed by means of a magnetic armature seal (8.1), arranged on a magnetic armature (8), in the unenergised state of the magnetic coil (11), by the force of a first spring element (9) acting on the magnetic armature (8), and is opened in the energised state of the magnetic coil. The differential piston (2) is under the influence of the force of a second spring element (7) in the opening direction of the valve plate (3), the force effect of which spring element (7) is less than that of the first spring element (9). A roller diaphragm (7) which is connected to the differential piston (2), separates the surge chamber (5) from the control chamber (6) and is constructed such that the valve plate (3) is in the opened position when it is in its destressed quiescent position, is used as the second spring element. The valve hence opens reliably even in the case of a very low medium pressure. <IMAGE>

Abstract: A refrigeration compressor is disclosed which incorporates an improved valve plate (26) assembly having selected portions thereof bowed outwardly to form discrete raised surface portions (A-B) thereon. These raised surface portions (A-B) serve to initially increase the clamping force on the gasket means (62) disposed between the valve plate (26) and head (52) or compressor housing (14) to thereby insure a fluid tight seal is maintained during operation of the compressor. Further the valve plate assembly incorporates dual suction valves oriented in side by side relationship and secured to the valve plate (26) at opposite ends.
