Abstract: FLUID PRESSURE DEVICE                         ABSTRACT      A fluid pressure device wherein a relatively low powered analog electrical signal readily controls the posi-tion of the output member of a fluid pressure powered actu-ator which in turn can be used to exert mechanical forces or operate mechanical devices such as fluid pumps, motors or valves.  Inlet and outlet passages communicate a pres-sure chamber to high and low pressures respectively.  A control element totally within the chamber so as to have balanced pressure forces thereon and made of a magneti-cally sensitive material is moved to a fixed position in the chamber by an externally generated magnetic field.  At least one of the passages moves with an output member of the actuator so as to be opened or closed by the control element relative to the other passage.  The output member follows the control element automatically varying the pres-sure in the chamber to compensate for any variations in the external forces thereon.          Alternatively, the output member includes a rod like element having a port in its side for one of the pas-sages and the control element is a sleeve surrounding the rod and can be moved by any externally controlled means including the magnetic field or an external mechanical interconnection.

Abstract: ABSTRACT OF THE DISCLOSURE     A pneumatic metal forming press which employs at least one pneumatic drive unit which has an expansion chamber defined by a flexible diaphragm acting on a support mechanism and a shock absorber underlying the support mechanism to absorb the impact thereof following the release of a working tool such as a punch after penetration of a work piece during a working stroke.  The drive unit may incorporate a plurality of diaphragm chambers arranged one above the other and connected in parallel to a source of high pressure air.  The drive unit may also incorporate a pressure multiplier having a fluid chamber pressurized in response to move-ment of the diaphragm of a drive mechanism and an output drive shaft driven in response to pressure thereto by the fluid in the multiplier chamber.  The drive mechanism may also incorporate a secondary drive mechanism operable to locate the working tool closely adjacent a work piece prior to commencement of the working stroke so that although the press may have a short working stroke, it has the ability to open and close over a substantial operating stroke.

Abstract: Abstract of the Disclosure The present invention relates to a method of sensing in advance the suitability of a planting point when plants are planted by means of a planting machine. A sensing means is pressed into or against the ground and is simultaneously vibrated. The resistance caused by the soil on said sensing means causes a change in the vibration and this change is measured and compared with predeter-mined reference valves representing acceptable planting ground conditions. In this way it is possible to get an indication of the suitability of the soil for the planting of plants at each planting point depending on the result of said comparison.      An apparatus for carrying out the method comprises a sensing means displaceable between a lowered ground contacting position and a raised position, a vibrator for vibrating said sensing means and a measurement indicator  for indicating the change in the vibration of the sensing means caused by the soil (Figure 1).

Abstract: ABSTRACT    A method for adding a reinforced labelled tab to a folder edge of a file folder of a file sytem is disclosed.  The tab is prepared by applying a plurality of labels to a carrier web which has a pressure sensitive adhesive backing covered by a removable protective strip.  A transparent reinforcing high tensile strength film is bonded to the carrier web and over the labels.  A tab extension member is added to an edge of a file folder by use of the carrier web.  The extension member is approximately the same thickness as the folder edge and the carrier web is of a width more than twice the width of the extension member so as to be securable to the spaced sides along the folder edge.  The protective strip is removed and the carrier web applied to both of the folder sides with the extension member secured between folded opposing adhesive portions of the web to provide a unitary labelled tab on a folder.

Abstract: -- A HOUSING FOR RADIO FREQUENCY APPARATUS, MORE        SPECIALLY ANTENNAS --ABSTRACT      A housing for radio frequency apparatus such as antennas is made up of ready-made shield elements which are put together for forming a cover or radom for the antenna. If moving supports in the form of metal frameworks for loads such as lifting gear or the like, are not to be used, it is necessary for loads to be fixed right on the hard foam shield, which may be made of polyurethane itself as a suppor-ting structure. For this purpose, at least some of the shield elements have support parts incast in them and made of a mate-rial with low attenuation properties with respect to radio frequency waves. Such a material may, for example, be glass fiber-reinforced synthetic resin or hard rubber. On the support parts, fittings may be placed for supporting the loads and the fittings, like the loads, for example in the form of a rail for supporting lifting gear, may be made of glass fiber-reinforced synthetic resin so as to cause little attenu-ation of radio frequency waves. Although the support parts are rooted only in the hard foam material of the shield ele-ments, a very high load supporting effect may be produced.

Abstract: ABSTRACT OF THE DISCLOSURE        A PCM signal processing apparatus adapted to receive successive transmission blocks, each of which comprise time-interleaved PCM data, error correction and error detection words.  The apparatus has detecting means responsive to the error detection words for detecting errors in a received transmission block and error identifying means for identifying errors in each of the time-interleaved words included in the received transmission block which has been detected. A de-interleaver is provided for time-deinterleaving each received transmission block to recover a de-interleaved block comprising de-interleaved PCM and error-correction words, with errors in the de-interleaved words being respectively identified.          A syndrome generating device is coupled to the de-interleaver for generating error syndromes using the de-interleaved PCM and error-correction words in the de-interleaved block. An error correcting device responsive to the error syndromes corrects erroneous PCM words in the de-interleaved block as a function of the remaining error free PCM and the error-correction words in the de-interleaved block.  An error compensating device is responsive to the identification of errors by the error identifying device and compensates the erroneous PCM words in the de-interleaved block with a substitute PCM word when error correction by said error correcting device is impossible. an inhibit device inhibits the error correcting device when all of the error detection words in the de-interleaved block are identified as erroneous and it discontinues inhibiting when the relationship between the identification by the error identifying device and the error syndrome indicates that no error exists.
