Patent DK-42084-A (DK)
Inventor: OLSSON OLE
IPC: A01J25/16
Filed: 1984-01-31
Abstract: A rack for use in a facility for storage and turning of cheese is turned at suitable intervals by means of a self- propelled turning mechanism, which can grab the rack from any side and thrust with a support plate against the particular side of the rack, after which the rack is lifted from its base, turned 180 degrees about an axis parallel to the front edge of the rack, and lowered onto the base. The rack is open on both sides and has a partition wall 3 which is mounted so that it is self- centring and can be shifted, for example, against the action of spring elements 4, toward either open side of the rack. To the partition wall 3 are fastened support rods 5, which project somewhat outside of both mentioned open sides. When turning the rack, cheese nearest the support plate of the turning mechanism will be supported by the latter in normal fashion. At the same time, the partition wall is moved by the turning mechanism toward the cheeses lying on the other side of the partition wall and supports them during the turning. After the turning mechanism drives away, the partition wall will be returned to the starting position, so that it is no longer in contact with the cheese. This avoids indentation marks on the cheese. <IMAGE>

Title: Multi-layered tissue paper web comprising chemical softening compositions and binder materials and process for making the same
Inventor: PHAN VAN DEAN
IPC: A47K7/00
Filed: 1994-06-28
Granted: 1999-07-31
Abstract: Multi-layered tissue paper webs comprising chemical softener compositions and binder materials are disclosed. The multi-layered tissue webs are useful in the manufacture of soft, absorbent paper products such as facial tissues and/or toilet tissues. The multi-layered tissue paper products contain a chemical softening composition comprising a mixture of a quaternary ammonium compound and a polyhydroxy compound. Preferred quaternary ammonium compounds include dialkyl dimethyl ammonium salts such as di(hydrogenated)tallow dimethyl ammonium chloride, di(hydrogenated)tallow dimethyl ammonium methyl sulfate. Preferred polyhydroxy compounds are selected from the group consisting of glycerol, sorbitols, polyglycerols having a weight average molecular weight of from about 150 to about 800, polyoxyethylene glycols and polyoxypropylene glycols having a weight average molecular weight from about 200 to 4000. The multi-layered tissue paper webs also contain an effective amount of binder materials to control linting and/or to offset the loss in tensile strength, if any, resulting from the use of the chemical softening compositions. The binder materials are selected from the various wet and dry strength additives, and retention aids used in the paper making art. Preferably, the majority of the chemical softening compositions will be disposed on the outer layers of the multi-layered tissue paper products where they are most effective. The binder materials are typically dispersed throughout the multi-layered product to control linting. In other words, the chemical softening compositions and the binder materials can be selectively distributed within the multi-layered tissue paper web to enhance the softness, absorbency, and/or lint resistance of a particular layer or ply.

Abstract: 672,888. Saw-tooth generating circuits. RADIO CORPORATION OF AMERICA. Jan. 13, 1949 [Jan. 24, 1948], No. 993/49. Class 40 (vi). [Also in Group XXXV] In a saw-tooth wave generator of the type in which a capacitor 2 is charged through a resistor 5 and discharged through a valve arranged in a blocking oscillator circuit, a sine wave voltage generated by means in series with the anode circuit is added to the voltage 68 (Fig. 2d) across the blocking capacitor 23 to make the blocking waveform 76 more steep at the end of the sweep period and thus the oscillator less sensitive to undesired triggering pulses. The sine wave may be produced by a resonant circuit 51, 52 tuned to the scanning frequency and shockexcited by the current through the valve. The synchronizing pulses may be applied to the cathode or to the tap on the transformer and may as in Fig. 3 (not shown) be used in an automatic frequency control circuit (see Group XXXV) which controls the charge on a capacitor connected between the grid and earth and thus rate of discharge of the blocking capacitor. The saw-tooth output is derived from a potentiometer 6 or from a capacitative potentiometer connected across the capacitor 2, in which case the output may be fed to an amplifier valve having a damping diode connected across the secondary winding of its output transformer. Specification 551,798, [Group XX], is referred to.
