Abstract: A METHOD OF RENEWING THE BRICKWORK OF COKE OVENS     Abstract of the Disclosure The invention relates to a method of partly re-newing the brickwork of the vertical heating flues of hori-zontal coke ovens.  In heating flues near the oven ends of horizontal coke ovens, the brickwork suffers much more severe wear than the central part of the heating walls.  In some cases, therefore, repairs are made only to the brickwork of the heating walls near the oven ends, up to the second, third or fourth heating flue.  During rebuilding, the heating flues towards the center are left at a higher temperature and the internal parts of the oven chambers are partitioned off by vertical walls. In the method according to the invention, a vertical cut is made through the oven wall of the innermost heating flue to be repaired, and the brickwork in front is pulled down.  The new parts of the oven wall are connected to the existing parts by oven bricks, which have a lug on the heating-flue side which engages over the existing oven bricks.

Abstract: Title of the Invention "Process for the measurement of the specific capacity of a cable and a device for carrying out the process"     ABSTRACT OF THE DISCLOSURE     In a process and device for measuring the specific capacity of an electric cable by means of a cylindrical measuring electrode through which the cable is passed and between which and the cable conductor an alterna-ting voltage is maintained, the capacitative current flowing between the cable conductor and a defined length of the electrode is determined by measurement of the currents flowing in the cable conductor at respective points located adjacent the ends of the defined length of the electrode, and obtaining the difference between the currents.  This avoids the need for direct measure-ment of the capacitative current and thus enables screening electrodes at each end of the measuring elec-trode to be directly electrically connected to or integral with the measuring electrode so that they can be main-tained at the same potential as the measuring electrode without the need for special electrical circuitry.  The means for sensing the currents in the cable conductor may comprise toroidal transformers having measuring windings connected in opposition, or, alternatively, they may comprise Hall-effect elements.

Abstract: ABSTRACT OF THE DISCLOSURE            A frequency synthesized receiver utilizes, as a local oscillator, a phase-locked loop circuit formed of a reference signal oscillator, a voltage controlled oscillator, a programmable divider, a phase comparator, and a low-pass filter.  For tuning to a desired frequency, the dividing ratio of the programmable divider is controlled by an up/ down counter connected in parallel with a shift register. The latter is supplied with a clock pulse signal and a binary coded selecting signal furnished from a micro com-puter.  The selecting signal corresponds to a desired broadcast frequency.  The up/down counter is caused by the micro computer to count up or down from the count value stored in the shift register, thereby causing the received frequency to rapidly sweep, at predetermined steps of, for example, 100 KHz.

Abstract: ABSTRACT OF THE DISCLOSURE The collimator assembly comprises a collimator shielding block for blocking undesired X-rays and an insert piece inserted into the shielding block.  The insert piece, which is made of a material of high atomic number, has an inner conical surface which defines the X-ray cone transmitting the insert piece and therefore the maximum field size which can be obtained for medical treatment. In order to supply different maximum field sizes, there are provided means for easily interchanging the insert in the collimator shielding block with another insert having a different interior conical dimension.  By using inserts of different cone angles, which can easily be inserted into the shielding block, for instance by means of a screw thread from below the shielding block, morbid tissues of different sizes can be treated while the surrounding healthy tissue is fully protected.

Abstract: ABSTRACT OF THE DISCLOSURE      In a time division switching system of the T-S-T arrangement, a speech path memory of each of forward and backward time switches has addresses corresponding to accom-modated lines and a speech signal and a non-speech signal (a signal indicating an on-hook or off-hook state and other control signals) are transmitted over a highway between each line module and a switch module.  When speech channel is busy, the speech signal is read out from a speech path memory and written therein and transmitted to a remote station.  Also when speech channel is idle, the non-speech signal is written in the speech path memory but, in this case, the non-speech signal is read out into a signal processor or a signal written in the speech path memory from the signal processor or a signal written in the speech path memory from the signal processor is read out on a line.  With this arrangement, a memory for the exclusive use of the non-speech signal, which is required in the prior art for non-speech signal transmission can be disposed of and transmission control of control signals of various line modules can be simplified.      The speech path memory is provided with a speech signal storage area and a non-speech signal storage area, by which it is possible to transmit a large amount of information as the non-speech signal in accordance with various line modules.

Abstract: (Case No. 80066 ABSTRACT OF THE DISCLOSURE     Brake apparatus for a railway vehicle including a brake cylinder device of the type having a pair of interconnected pistons of unequal size to which the vehicle braking rigging is connected, the larger piston having first and second chambers formed on its opposite sides in which air is stored for use in controlling the vehicle brakes, and a control valve device that is operative responsive to a reduction of brake pipe pressure to transfer air from the first chamber to a third chamber formed on the side of the smaller piston corres-ponding to the side of the larger piston having the second chamber, to effect movement of the interconnected pistons to a brake application position.  As piston displacement occurs, pressure in the second chamber is equalized with the pressure in the third chamber so that no pressure differential is developed across the larger piston, until a predetermined pressure is established in the third chamber consistent with a desired minimum brake application force.  When this occurs, the control valve exhausts air from the first chamber, the volume of which is minimal in brake application position of the larger pistons, so that with but a small loss of air from the first chamber, a large pressure differential may be estab-lished across the larger piston by reason of the pressure in the second chamber being trapped at a substantially constant value, thus providing higher brake application forces with but a minimum of air consumption.
