Title: Mop thread-squeezing apparatus
Inventor: KAMADA KATSUZO
IPC: A47L13/59
Filed: 1996-02-27
Abstract: A  mop  thread-squeezing  apparatus  capable  of compressing mop thread sufficiently without deteriorating the operability thereof, by applying a great pressing force to the mop thread.  A pinion fixed to a driving shaft and a rack supporting one end of a squeezing plate are installed on each of left and right side plates of a squeezing tank.  A radius of a pitch circle of the pinion at a point of contact between the pitch circle of the pinion and a pitch line of the rack becomes gradually smaller in a region corresponding to a former half time period of a lever operation and is almost constant in a region corresponding to a latter half time period of the lever operation.  In the former half time period of the lever operation,  a squeezing plate moves downward rapidly and thus the amount of the downward movement thereof is great, whereas in the latter half time period of the lever operation, the radius of the pitch circle becomes smaller and thus the  pressing  force  of  the  squeezing plate becomes greater.

Patent CA-2174723-A1 (CA)
Inventor: KOEHLER MICHAEL
IPC: C07C31/125
Filed: 1994-10-12
Abstract: The invention concerns a method of producing fatty alcohols with an iodine number between 20 and 110 from vegetable oils, the alcohols consisting essentially of unsaturated fatty alcohols or mixtures of saturated and unsaturated fatty alcohols of the general formula (I): R1OH, in which R1 is a saturated or unsaturated straight-chain or branched-chain alkyl group with 8 to 22 carbon atoms. Using prior art methods, the triglycerides contained in the vegetable-oil raw materials are (a) decomposed under pressure into the constituent fatty acids and optionally esterified with methanol or (b) transesterified to give the fatty-acid methyl esters and (c) the fatty acids or fatty-acid methyl esters are hydrogenated to give fatty alcohols. The method is characterized in that the fatty acids, the fatty-acid methyl esters and/or their hydrogenation products are fractionally distilled and the first runnings taken from the distillation, the end product having an iodine number from 20 to 110. The invention also concerns fatty alcohols produced from vegetable oils having an iodine number from 20 to 95 and the use of fatty alcohols produced from vegetable oils in the manufacture of washing, rinsing and cleaning agents as well as hair-care and body-care agents.

Title: Apparatus and method for scheduling and rescheduling incoming requests
Inventor: OZDEN BANU
IPC: H04N7/173
Filed: 1996-06-06
Abstract: A method for retrieving video data which has been striped across a plurality of disks using a coarse-grained striping technique. Specifically, and in accordance with an illustrative embodiment of the present invention, the method comprises scheduling the retrieval of a video in response to an incoming request and based on the availability of bandwidth on the disks, and then rescheduling the retrieval of that video to occur at an earlier time, the rescheduling based on a change (i.e., an increase) in the availability of bandwidth on the disks which results from the retrieval of another video being completed. The scheduling and rescheduling may, for example, comprise assigning a disk to the video, where the method further comprises incrementing the disk assigned to the video as each round occurs and beginning the retrieval of the given video when the disk assigned to it is the disk on which the data for the given video begins.

Abstract: A refrigerant pump system wherein the outdoor coil is larger than the indoor coil to provide for efficient operation when the system is in a cooling mode. A refrigerant reservoir is mounted in a refrigerant line that connects the two coils during a heating mode which is arranged to collect liquid refrigerant, thus preventing the outdoor coil from becoming overcharged with refrigerant during the heating process. Efficient operation of the system is thus maintained during both heating and cooling without the need for expensive equipment to regulate the flow of refrigerant between the heat exchanger coils.
