Title: Film fibrillation apparatus
IPC: D01D5/42
Filed: 1973-03-23
Abstract: 1459398 Fibrillating films SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 21 March 1974 [23 March 1973] 14208/73 Heading B5B A film, preferably of polyethylene or polypropylene, is fibrillated by passing it under tension through the nip of a pair of contrarotating drums or rollers, each of which is provided with needles projecting from its surface. The needles are so arranged that, during operation, they do not touch each other. The drums or rollers are driven at a peripheral speed greater than the linear film speed, but do not necessarily have the same speed as each other. Means are provided to vary the arc of contact formed by the film with at least one of the drums or rollers. In Fig. 3(a) this means takes the form of allowing the drum 22 to rotate around drum 23. Other means include a feed roller 24 which, as shown in Fig. 3(c), may be moved in a direction other than parallel to the film. Two films may be fibrillated simultaneously as shown in Fig. 3(d). Each film is then provided with an adjustable degree of wrap, for instance by the movable feed rollers 25, 26. Alternatively the films may be fed together as in Fig. 5(a) (not shown). The needle clearance may be provided by causing the needles on one roller to intermesh with those on the other, by keeping the rollers far enough apart to avoid contact, by providing grooves on the roller surface into which the needles of the other roller fit or, similarly, by fixing the needles on axially arranged bars which stand proud of the roller surface leaving a space for the other roller needles to fit. The resulting filaments acquire a crimp if the cutting elements are heated.

Title: Improvements relating to the manufacture of welded tubes by electric resistance welding
IPC: B23K11/06
Filed: 1924-06-14
Abstract: 239,614. Schr÷der, E. June 14, 1924. Welding.-In a process of electrically welding tubes by a series of roller electrodes which operate in succession on the same seam and either roll step by step, or are continuously rotated and the current intermittently interrupted, one or more of the electrodes serve to preheat the seam to a temperature below the welding temperature and the remainder weld the seam. The electrode E, Fig. 3, renders the seam plastic, and the pressure rollers D, D<1> bring the seam faces together, whereupon the pressure rollers D, D<1>, Fig. 4, force the seam outward in the form of a pointed arch so that the inner edges of the seam first come into intimate contact and the current passes from the roller E<1> across to the short-circuited pressure roller D<1> and the seam is thus welded from within outward across the seam. The electrodes are arranged so that the zone of the second slightly overlaps that of the first and the zone of the third that of the second. If six electrodes are used the first, third, and fifth may act as preheaters, and the second, fourth and sixth as welders. The rollers D<1> are short-circuited conveniently as described in Specification 214,130.

Title: Process for the manufacture of physiologically active derivatives of cyclopentano-phenanthrol
IPC: C07J1/00
Filed: 1934-11-23
Abstract: Saturated or unsaturated 3 : 17-diketones of the cyclopentono - dimethylpolyhydro - phenanthrene series of the formula C19H28O2 or C19H26O2 respectively are reduced to the corresponding di-alcohols. The conditions under which the reduction is effected determine the proportion in which the different isomeric forms are produced. Thus on reduction in neutral and alkaline media a preponderating amount of the trans form is produced, whereas in acid solution it is the cis form which predominates.  In examples: (1) the saturated diketone obtained according to example 1 of Specification 448,183 is hydrogenated in glacial acetic acid using platinum as a catalyst; (2) the unsaturated diketone obtained according to example 2 of Specification 448,183 is hydrogenated as in (1) to yield the same saturated di-alcohol; (3) the unsaturated diketone obtained according to example 3 of Specification 448,183 is reduced by the action of sodium in alcohol to give a dihydroxycyclopentanodimethyltetradecahydrophenanthrol of the formula C19H32O2.

Leakage-preventing devices; balancing moving parts.-A centrifugal pump has rings 4, subject to the action of springs 5 or to the pump pressure, arranged to prevent the pumped liquid from passing back from the discharge side to the bearings. In the single suction pump shown in Figs. 1 and 4, the rings are fitted in a recess 6 in the casing with a spring the pressure of which may be varied by the screw pin 10. The face of each ring is held against the facing 12 on the impeller 3; the ring face has a lubricating-space 8, and packing 7 prevents the passage of liquid into the recess 6. In a modification, the ring is provided with a lip 15, Fig. 6, exposed to the pump pressure to hold the ring against the impeller. A light spring is provided to hold the ring in position when the pump is not working. The ring may be carried by the impeller and pressed against a facing on the casing. In another modification, Fig. 8, the ring is divided and packing 7 placed between the parts. The spring 5 that holds the ring against the face 12 also presses the packing against the sides of the recess 6. The rings may be placed so that liquid under pressure at the back of the impeller balances the axial thrust.

Abstract: 597,421. Piezo electric vibrators. SUBMARINE SIGNAL CO. June 8, 1945, No. 14638. Convention date, July 8, 1940. [Class 40 (iv)] [Also in Group XL] A piezo-electric oscillator for transmitting and receiving compressional waves includes a longitudinally resonant vibratory element in which crystals are held between end shoulders with their mechanical axes parallel to the axis of the longitudinally vibratory element and their electric axes transverse thereto, the node of the longitudinally resonant element being between the crystal supporting end shoulders. In one construction, the resonant element may be recessed on opposite sides to form spaces with end shoulders to retain the crystals. In an alternative construction, the element may consist of an elongated member connected to two end masses whose surfaces form the shoulders to hold the crystals. In the unit illustrated, the element is held to a plate 24 by a screw 23. The bottom shoulders on the element may be omitted, in which case the plate 24 itself provides the shoulder surface to hold the crystals 19. The cross-section of the unit may be any regular polygon. Groups of units are mounted to cover the surface of a plate 9 which is supported through a thin flange 10 and a heavy periphery ring 11 from a casing 12.

Title: Communication switching system
IPC: G06F15/17
Filed: 1976-04-09
Abstract: 1532486 Data transmission; pocket switching INTERNATIONAL BUSINESS MACHINES CORP 9 April 1976 [5 May 1975] 14639/76 Heading H4P A modular communication switching system comprises a plurality of switching processor modules PSM for transferring data packets between the various ports of line attachment modules LAM, each processor module being assigned to a particular LAM or group of LAM's for monitoring purposes and each including a store and processing circuitry for the compilation, buffering and transmission of data packets in connection with the LAM's. In operation, when data is to be transferred from a line associated with a port of LAM2 to a line associated with a port of LAM4 for example, the transfer is effected as follows: (a) LAM2 requests a buffer section in PSM1 and if this is available, (b) a  data packet is transferred into the buffer character by character. (c) A request to transmit is then sent from PSM1 to PSM3 which is assigned to LAM4, and (d) PSM3 ascertains that the required output line is available. (e) A transfer request is then sent from PSM3 to PSM1, which then, (f) transfers the buffered data packet directly to LAM4 over a common BUS line.(g) PSM3 monitors the transfer, receives an acknowledgment of receipt from the next switching node, and (h) sends a message to PSM 1 so that the latter can release the allocated buffer storage. A module NCM controls and monitors the operation of the switching system as a whole. The NCM contains the necessary programs for establishing and terminating connections (both circuit switched and virtual), and has error control functions which are called upon to handle failure conditions in the PSM's or LAM's which cannot be managed by these modules alone. If, in step (a) above, a buffer section is not available in the requested PSM, the request is transferred to the next PSM (and so on) which then acts to monitor the subsequent data transfer (Fig. 3b, not shown). If the input and output lines are associated with a single LAM, then all the transfer steps are effected by the single associated PSM (Fig. 3c, not shown). Suitable arrangements for the PSM's and LAM's are described with reference to Figs. 4 and 5 (not shown). The arrangement is such that the PSM's cooperate in pairs to receive data etc. and to monitor its transfer, whereby a large flow of traffic is separated into many small flows involving relatively short, simple or independent procedures so that overheads and housekeeping operations are reduced.
