Patent MX-9710490-A (MX)
Title: Mobile telephone system.
Inventor: GOETZ IAN
IPC: H04M3/22
Filed: 1996-07-17
Abstract: A mobile telephone system consists of a base transceiver station (BTS) that provides radio communication with a mobile handset (MS) and also communicates with a control station (BSC) through a communication link in the form of a leased line which provides a first communication path (P1) with a predetermined bandwidth for signals communicated between the BTS and the BSC. A communication network in the form of an ISDN is used to provide a selectively connectable second communication path (P2) between the BTS and the BSC so as to augment the bandwith available for the signals during periods of peak demand. In order to accommodate different call connection times in the system through the leased line and the ISDN, the BSC/BTS are arranged to produce call connection signals (CLI1, CLI2) that initiate billing at the same time irrespective of the path P1, P2 used to make the call connection.

IPC: C08K5/053
Abstract: 1,009,066. Rotary 1.C. engines. W. B. McCALL. Aug. 1, 1962, No. 29590/62. Heading F1F. A rotary internal combustion engine comprises two rotors 14 and 18 rotating about axes at right angles to one another and having peripheral cut-outs 33, 34 and 35, 36 respectively which engage the remaining peripheral projections 51, 52 and 49, 50 respectively as the rotors rotate. An inlet and an exhaust opening communicate with each rotor chamber, and are separated by rotary abutments 60, 65 which have cut-outs to allow the peripheral projections of the rotors to pass. As the rotors rotate, fuel-air mixture is drawn into the cut-outs 34 and 35 (see Fig. 2) on the inlet sides of the abutments, and, considering only the charge in the cut-out 34, is compressed against the flank of the portion 52, which is then in engagement with the cut-out 34, into an adjacent combustion chamber, where it is ignited and allowed to expand into the cut out portion 35. The stages of the working cycle appear in more detail in (Figs 5-8 not shown). Throttle valves may be fitted in the inlets and exhaust openings, to control the power output and to provide engine braking. The engine may operate by spark ignition or compression ignition.
Patent NL-6818297-A (NL)
IPC: D04H3/10
Filed: 1968-12-19
Abstract: Shaped felts are produced by forming a mat of crimped continuous synthetic textile filaments, subjecting a portion of the mat to a needling operation and moving the mat in relation to the needles until the entire surface of the mat has been pierced by the needles. The continuous filaments may be crimped then assembled under tension in substantially parallel form into a mat and then relaxed or alternatively the mat may be formed of potentially crimpable fibrous material and subsequently crimped by the action of water or evaporation of a solvent.  Fibres which may be included in the felt include rayon, nylon and polyethylene terephthalate.  Two or more layers may be needled together or a mat of the fibres may be needled to a base fabric, e.g. of cotton which may be woven or knitted, or to a base material comprising an elastomeric material.  Binding agents such as thermoplastic resins may be added to the yarns or to the web before, during or after needling.  A tennis ball core wound uniformly with a crimped nylon continuous filament yarn (see Division B8) is placed in slightly compressed condition between a rotatable table (45) and a needle plate (38) and subjected to a needling operation by means of a needling head (41), Fig. 5 (not shown).  The table (45) is not only rotated but is moved in a direction parallel to shaft (47) so that the entire surface of the ball is needled to produce a felt-like surface.  To prevent puncturing of the rubber core the needles used are provided with one barb formation only (Fig. 5a, not shown).  In an alternative embodiment (Figs. 1-3, not shown), an endless belt is produced by needling a belt of continuous filament nylon 66 yarn on to a woven cotton fabric base supported on two rotatable rollers.  Rotation of the rollers causes the entire surface of the belt to be presented in the area in which needling takes place.ALSO:A tennis ball is formed by winding a crimped nylon continuous p  filament yarn uniformly on a rubber core placing the core in a slightly compressed condition between a rotatable table and a needle plate and subjecting the assembly to a needling operation. The table is not only rotated but is moved perpendicularly to the axis of the table so that the entire surface of the ball is needled to produce a felt-like surface.

Title: Commercial greenhouse ventilator coupling rod - has locking mechanism at opposite end functioning until drive is switched on again
IPC: E05F15/12
Filed: 1978-04-03
Abstract: The driven coupling rod with locking mechanism is for use in opening ventilators in greenhouses etc. After driving the rod a locking mechanism (5) acting at the opposite end, comes into operation until the moment when the drive (4) is switched on again. The rod can be arranged to withstand only a small pressure load, and when this becomes too great a small elastic kink is formed, causing rod length to be reduced. This results in a tension load from the locking mechanism on the rod, so that it does not permanently distort.

Abstract: Multiple stage cryogenic pump for transferring matter, e.g. ions or a strip of material to be treated, between a gas and a vacuum chamber has an orifice in the vacuum chamber through which some of the gas leaks into the chamber. The chamber is divided into several regions by internal divider(s) each having an aperture through which the matter travels. The interior surface of the chamber is cooled by a single refrigerating device to below the condensn. temp. of the gas to establish different sub-atmospheric pressures in each region. The device is used for transferring ions into a vacuum for analysis by a mass spectrometer. The spectrometer is located in an operating region, which is the highest vacuum region, and the gas is pumped to successively lower pressures in a series of stages between the inlet and the operating region. It can also be u sed for vacuum deposition of metal onto a metal or plastics strip.
