Patent EP-0278630-A2 (EP)
Inventor: PERSEM JACOB P
IPC: F25B49/02
Filed: 1988-01-27
Abstract: A refrigeration compressor system using a reciprocating compressor (42) with continuously variable capacity. The speed of the compressor (42) can be varied substantially continuously over predefined range of speeds. A controller (40) for the compressor (42) monitors one or more physical parameters indicative of the temperature of the application being refrigerated, such as the temperature itself and/or pressure in the compressor's refrigerant suction line. Using a predefined algorithm, the controller (40) adjusts the speed of said compressor (42) so as to keep said monitored parameter within a predefined target range. 
     In a preferred embodiment, the compressor (42) is an open direct drive compressor. The compressor's motor (44) has a substantially continuous range of useable operating speeds which varies by a ratio of more than two to one. Furthermore, the controller (40) has a plurality of control strategies for adjusting the speed of the compressor's motor (44), including one for adjusting the motor's speed in accordance with the difference between the measured temperature and a specified target temperature, one for adjusting the motor's speed in accordance with the difference between the pressure in the compressor's refrigerant suction line and a specified target temperature, and one for adjusting the motor's speed in accordance with both the temperature and suction pressure.

Abstract: A solid hyrdated stick for topical applica­tion containing emulsified water soluble ingredients and volatile emollients. The stick is a solid emulsion comprising by weight from 15% to 40% of a cyclic silicone, 2% to 15% of an oil, 2% to 20% of a wax, 2% to 7% of polyethylene glycol sorbitan beeswax, 10% to 40% water, and 0.1% to 40% of a cosmetically acceptable functional ingredient. The polyethylene glycol sorbitan beeswax acts as an emulsifier and contributes to the rigidity of the stick, while the silicone serves as an emollient to impart a smooth, buttery feel when the composition is applied to the skin.

Abstract: A logging apparatus for investigating properties of earth formations while a borehole is being drilled is proposed to comprise a tubular drill collar (14) adapted to be coupled to a drill string and adapted to permit the flow of drilling fluid lengthwise through its interior. A radiation source and detector (16, 17) are positioned within the collar. The collar and source are configured so that the source is removable from the uppermost end of said drill collar. A system is provided for detecting and removing effects unrelated to the property being investigated such as microphonic noise where the source and detectors are for neutrons and natural background and tool activation where the source and detectors are for gamma rays. With gamma rays, external fluid excluders including gamma ray transparent windows adjacent to the source and the detectors are provided and a gamma ray detector system across an interior drilling fluid passage from the source may be included for determining the photoelectric absorption coefficient and the density of the drilling fluid.

Abstract: In a short-coupling device for a trailer train consisting of a heavy goods vehicle and a trailer, a guide rail is provided in the region of the end wall of the trailer, which guide rail extends continuously rearwards, also in each case for a certain distance along the sides of the trailer. The trailer traction fork engages via guide elements with the guide rail, so that in the steering positions the traction fork follows the course of the guide rail, the traction fork being mounted longitudinally displaceably on the live ring of the trailer. As a result, the distance between the trailer and the heavy goods vehicle is automatically increased in the event of a steering movement and automatically reduced in the event of a decreasing steering movement. <IMAGE>

Abstract: In order to be able to dispense with control apparatuses, which are expensive in terms of construction and energy, in the cyclic advancing of a series of objects to be cut into slices, it is proposed to exert an advancing pressure continuously on the series of objects, which is limited to an upper and a lower pressure value by the fact that an accumulator (20) is stressed when an adjustable maximum pressure is exceeded and the accumulator (20) is unstressed when the pressure drops below an adjustable minimum pressure. When the maximum pressure is reached, the accumulator (20), becoming loaded, prevents a further increase in pressure and, when the pressure drops below an adjustable minimum pressure, the accumulator (20), becoming unloaded, prevents a further drop in pressure.

Abstract: A surface cleaner that may take the form of a surface strength tester or lint remover for paper wherein lint or like material is freed from the surface of a paper web travelling past the cleaner. The cleaner includes a material pick-up head having an air bearing surface through and along which an air stream is passed to generate an air bearing and a significant negative air pressure between the bearing surface and web. The negative pressure tends to hold the web and air bearing surface in close proximity to each other and causes lint material to be freed from the web surface. The freed lint material is carried in the air stream. A vacuumed pick up has its inlet opening located relative to the air bearing surface such that material freed and carried in the air stream is sucked into the inlet. If the cleaner is used as a tester the pickup head may extend over only a small portion of the web surface and the amount of material measured thereby to provide an indication of the linting propensity of the web. If the cleaner is to clean the surface of the web the pickup head will extend over substantially the full width of the web.

Abstract: A laser printer records an image on a medium as a function of digital data which is received at an input data rate. A laser beam is used for recording pixels of the image on the medium while the medium is advanced in a longitudinal direction at a controlled uniform rate. The pixels are recorded by scanning the beam across the medium in a transverse direction, at a scan velocity, using a multifaceted, rotating mirror which reflects the beam onto the medium. The scan velocity is proportional to the angular velocity of the rotating mirror. Beam intensity is modulated as a function of the input digital data. In order for the average data rate of recording to be compatible with the input data rate while maintaining a high instaneous scan velocity, the beam is scanned across the medium by only one of every N-facets of the rotating mirror.

Abstract: A computer system is provided for obtaining and recording information by presenting selected data, warnings and inquiries on a computer display monitor, prompting selected responses to the warnings and inquiries as desired, and integrating newly obtained information with other data to create a completed document. The system creates "dialog boxes" which are defined by an expert operator. To create a dialog box, the operator defines a location in the document in which a question is to be asked or information provided to the user. The operator also defines the question or information, and can also provide several responses to the question. The operator can specify the number of answers which can be accepted in response to an inquiry, and can specify that certain information, such as a date or the like, be provided. 
     The dialog boxes can be arranged in an information tree structure having multiple branches. The branches of the tree which are actually used are determined by the responses received to inquiries as information is obtained. Macros can also be integrated into the tree structure, if desired. The operator's selection of sequential responses to the questions thereby determines how the document develops. As questions are answered, the information obtained is inserted into the text of the completed document, and the inquiries are erased. In this manner, someone having expert knowledge in a field other than computer programming can develop a system which persons with less knowledge in the field can use to obtain information and assemble it in an integrated and easy to understand narrative text format.
