Title: Expansive cement compositions
IPC: C04B22/10
Filed: 1979-04-24
Abstract: The invention relates to expansive cement compositions and to expansion agents containing free lime for use in such composition. Novel expansion agents are prepared by heating lime of particle size less than 250 microns and comprising at least 36 wt % of CaO in an atmosphere comprising water vapor at 100 to 400 DEG C or carbon dioxide at 350 to 850 DEG C when the particles contain less than 8 wt % Ca(OH)2, or by heating a partially hydrated lime at a temperature of at least 100 DEG C when the particles contain from 8 to 64 wt % Ca(OH)2. The encapsulated limes produced in this way are useful as expansion agents in hydratable cement compositions, the amount thereof generally being less than 30%, preferably 3 to 10%, based on the weight of the cement and the additive. Cement compositions containing the novel expansion agents are useful where shrinkage of the composition on drying has to be prevented or reduced.

Title: Proportional drive of the tools of an agricultural machine.
IPC: A01D41/127
Filed: 1979-11-14
Abstract: In agricultural machines, it is often necessary to drive the planting, processing and/or harvesting tools in synchronism with the driving speed of the machine or with a percentage lead or lag in relation to the driving speed of the machine. In this agricultural machine, the object is, by the use of a non-driven wheel running on the ground, to provide a control device which within wide limits allows any desired speed or distance relationship, whilst maintaining the linear dependence on the driving speed, between the driving speed or driving distance and the rotational speed or distance of the working tool. To achieve this object, there is a first inductive transmitter (16) connected operatively to the running wheel, for generating a distance-dependent or speed-dependent signal, and a second inductive transmitter (17) connected operatively to the working tool, for generating a signal corresponding to the distance or speed of the working tool. Electronics (18) serve for comparing the two signals and for entering additional correction signals. Only the signals are therefore treated and processed, and this can be carried out very easily by means of electronics. The drive of the working tools is then varied accordingly by means of an adjusting device.

Patent ES-8105533-A1 (ES)
Title: Arrangements for data timing recovery from distorted signals for use in adaptive modems with multi-level coding.
IPC: H04L25/03
Filed: 1980-09-12
Abstract: The submission makes use of the fact that where an adaptive equaliser (APS) is incorporated in a modem, some sort of training sequence is employed prior to the transmission of the data message. This training sequence usually incorporates a block of pseudo-random data (DIS) transmitted at the basic symbol rate to provide the equaliser (APS) with a relatively less distorted signal to operate on. During the training period both threshold-derived timing (TCTRL) and Nyquist-derived timing (NTRL) are produced. The Nyquist-derived timing (NTRL) is then phase-shifted (APS) to correspond to the threshold derived timing (TCTRL) which is valid during the training period. The phase shift (APS) is then fixed so that, when multi-level coding is introduced valid timing can still be obtained from the Nyquist-derived timing signal (NTRL). In addition in the event of transmission interruptions the invention allows timing recovery without the need for a new training cycle.

Title: Catheter device.
IPC: A61M25/00
Filed: 1981-05-28
Abstract: A catheter device (1) is disclosed which is intended either to work as a catheter per se or to work as a catheter adapter to be connected to a conventional catheter. The device is of that type which comprises a channel (5) intended for the liquid to be drained from a body cavity (2), and a channel for the inlet of gas, usually air, into the liquid channel (5) to break a liquid column in the liquid channel. An especially preferable use of the device according to the invention is for the drainage of a urinary bladder. Previously known devices for the inlet of air have been provided with some form of a bacterium filter. According to the invention the need of a bacterium filter is completely eliminated. This is achieved by the fact that the gas channel (6) comprises two openings, the first one of which opens into a liquid collecting means (4) and the second one of which (9) opens into the liquid channel (5) upstream the outlet of the liquid channel into the liquid collecting means. Through the fact that the rest of the gas channel (6) is closed from the surrounding a totally closed gas circuit is obtained, wherein the gas intended for entrance into the liquid channel (5) is taken from the liquid collecting means (4). Thus, there will be no need of any gas from the outside. According to a preferable embodiment of the device the gas channel (6) is dimensioned more narrow than the liquid channel (5).
