IPC: D02G1/14
Filed: 1938-01-07
Abstract: 508,968. Crimping fibres, yarns, &c. TAYLOR, W. I., and GIBBINS, L. B. Jan. 7, 1938, No. 581. [Class 120 (iii)] Filaments, fibres, yarns, &c. are crimped by deforming them by lateral pressure locally applied in the presence of an agent adapted to soften the substance of the filaments &c., and by simultaneously rubbing the materials in a direction transverse to the direction of application of the pressure, the deformed materials being then removed from the influence of the softening agent so as to set the deformations therein ; the pressure may be applied by passing the filaments &c. between rollers having intermeshing corrugations and the softening agent may be hot water or wet steam, which may contain the vapours of another softening agent and a liquid adapted to facilitate the softening of the material may be applied thereto before the application of the lateral pressure. As shown, the rollers 13, 14 having intermeshing corrugations 15 are mounted within a jacketed chamber 6 and are geared together and driven from outside the chamber by chain and sprocket gearing ; the filaments &c. 1 pass into.and out of the chamber through small slits 12, 33 and before passing between the rollers is subjected to steam from a jet 31 supplied by a pipe 32. The filaments &c. pass from a supply, through a tension device, and over a roller to a guide 11 before entering the chamber and through a guide 34 after leaving the chamber on the way to a take-up device. The shaft of the roller 14 and its gear-wheel is slidingly mounted in its bearings 18, one end of the shaft bearing against a spring- pressed ball and the face of the gear-wheel carrying projections 24 which engage a fixed projection 25 as the rollers rotate and cause the roller 14 to move transversely and rub the filaments &c. The chamber has a drain cock 36 and one side may be removable for threading the filaments &c. in the slits 12, 33 which are formed by long slots overlapped by the side plates of the chamber ; escape of steam from the chamber and undue stretching of the filaments &c. may be prevented by compressed air supplied to auxiliary chambers covering the slits 12, 33, e.g. in the manner described in Specifications 443,707 and 443,773, [both in Group IV]. The chamber may be jacketed with steam, e.g. when the softening agent applied to the filaments &c. is a mixture of air and a solvent vapour. The crimped filaments may pass from between the rollers, around the lower roller and between it and a rubber nip roller to the surface of a hollow heating element fed with steam.

Filed: 1923-01-09
Abstract: 196,889. Krupp Akt.-Ges., F. April 26, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Calendering.-In apparatus, such as roller calenders, in which a web of paper or fabric is unwound from a supply roll and rewound on a receiving roll, a part of the power supplied to the unwinding mechanism is caused to drive the winding mechanism or other part of the apparatus whereby a proper unwinding tension in the web is produced without the necessity of providing a friction brake on the supply roll. As shown, the supply roll E rests loosely on a roller D and the web B passes round the roller D and calender rollers C to a receiving roll H resting kosely on a pair of rollers F, F<1> geared together. A pulley d' fast on the shaft of the roller D is connected by a belt J to a pulley f<2> connected to the shaft of the roller F by a one-way clutch, so that the pull on the web B due to the rotation of the rollers C serves to rotate the roller D to unwind the web from the roll E and at the same time to wind the web on the roll H. The tension of the belt J and consequently the maximum tension which the web R may have is controlled by a bell-crank lever M<1> carrying an adjustable weight m<2>. The shaft of the roller F is connected to the lowermost roller C by a belt. Q and if the web should break, this belt serves to wind the remaining web on the roll H.

Title: Device for gripping work pieces
Inventor: SCHNEIDER RUDOLF
IPC: B25B5/02
Filed: 1988-07-07
Abstract: The invention provides a clamping apparatus, particularly for receiving and clampingly retaining electrode body blanks having prismatic or circular cross section for erosive machining devices. A clamping block has at one of its surfaces an essentially centrally arranged clamping chamber to receive the electrode. Two adjacent walls of the clamping chamber are provided with clamping screws protruding into the clamping chamber. An approximately central position of the workpiece in the clamping chamber is achieved by the provision of distance plates with preselectable thickness, which are inserted into the clamping chamber between two walls thereof and the surface of the workpiece, before the workpiece is clamped by tightening the clamping screws. This clamping apparatus is inexpensive and rugged, so that the electrode, once machined and used, respectively, may always remain clamped and therefore may be used again with a very high precision as far as its position is concerned.

Patent JP-S5592889-A (JP)
Title: Heat accumulator
Inventor: RIYOUDORI MICHIO
IPC: F28D17/00
Filed: 1979-01-08
Abstract: PURPOSE: To take out heat from heat accumulator at a high efficiency, by reducing resistance to heat transfer from heat accumulating material to cooler.  
     CONSTITUTION: When coolant is passed through cooler 3 for absorbing heat, volatile liquid 5 existing in the vicinity of cooler 3 is cooled. By the temperature difference thus caused, volatile liquid 5 existing inside communicating passages 7 receives heat produced from heat accumulating material 2, from the inner surface of passages 7. As the result, liquid 5 is boiled and carried near to the upper cooler 3, where it is condensed through releasing of condensation heat. This volatile liquid 5 is carried back to the lower passages 7. Through repetition of the above cycle, liquid-like heat accumulating material 2 is condensed and crystal 2a of heat accumulating material sticks onto the inner wall surface of passages 7 in reservoir chamber 6. When thickness of the crystal 2a has increased to a certain value, supply of coolant to cooler 3 is interrupted and heating medium is passed through heater 4. With such an arrangement, resistance to heat transfer from heat accumulating material 2 to cooler 3 can be reduced with no need of considerably increasing the overall length of pipes constituting the cooler 3 and heater 4.
