Abstract: A B S T R A C T        A device for use in water drains provided with an outer drain grating for preventing accidents and coarse material falling into the drain. The device is intended for separating and collecting particulate impurities, such as sand, wooden pegs and leaves, and also oil and other liquid impurities passing through the grating. To this end, the device includes a holder ring intended to be mounted under the drain grating, and carrying the combination of a coarse-filtering and protecting means and a fine-filtering means. The coarse-filtering and protecting means is cup-shaped and arranged in the holder ring, while the fine-filtering means comprises a filter bag of a flexible and water-permeable cloth or fabric material arranged around the holder ring. The holder ring is preferably funnel-shaped and provided with a mounting flange arranged to be firmly clamped beneath the drain grating, and the coarse-filtering and protecting means comprises preferably a wire basket.

Abstract: ABSTRACT OF THE DISCLOSURE     A microprogrammed control unit with multiple branch capa-bility comprises in addition to a control memory, a first auxiliary read/write memory having low parallelism and a second auxiliary read/write memory having high parallelism.  The reading of a micro-instruction from the control memory also causes the reading of in-formation from the first auxiliary memory, such information being used to address the reading of the second auxiliary memory.  The information read out from the second auxiliary memory specifies jump conditions to be examined and jump addresses, and extends the informa-tion contained in the microinstruction read out from control memory.          Thus it is possible to associate jump microinstruction to operative microinstructions and paricularly multiple branch microinstructions to curtail the design time of the microprograms and the control melory size devoted to store them.  A priority network coupled to the second auxiliary memory determines the priority to be followed during the concurrent examination of several jump conditions and selects the jump address among several possible addresses according to the veri-fied jump condition having the highest priority.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention refers to a procedure and a device for measur-ing the degree of compaction attained when compacting a foundation by means of a vibrating compaction tool. The movement of that part of the compaction tool which rests on the foundation is sensed and analysed. The time interval elapsing between successive passages of the movement signal through the zero point or other reference level is measured. Alternatively, the ratio between the absolute values of the extreme positive and extreme negative values of the motion in relation to the said level is also measured. By means of the relative magnitudes of these time intervals and amplitude relationships respectively a quantity is formed which comprises a measure of the degree of compaction of the foundation. The invention also refers to electronic devices which sense the movement and calculate the time intervals and amplitude relationships and calculate a quantity as a function of these, which comprises a measure of the degree of compaction attained in the foundation.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of determining the precise location of an edge of a strip with  individual  elements  of  a  radiation responsive sensor to an accuracy exceeding the pitch of  the elements is disclosed.  The strip is scanned at least in the region of the edge  with  the  individual  elements  of  the radiation  responsive  sensor.   Each  element generates  a signal value associated therewith  for  each  scan  and  the signal values for all the elements form a  composite  signal having discrete values representative of radiation  received from   the   scanned   region   at   respective    locations corresponding to the individual elements of the  sensor.   A region of interest where said  edge  is  likely  to  lie  is identified and the composite signal is analysed by defining a curve  which  when  the  values  are  plotted  against   the locations on a distance scale passes through the  values to represent a radiation  profile  of  the  scanned  region  as received by the sensor.  The point of maximum slope  on  the curve is then found and the corresponding  position  on  the distance scale taken as representing the precise location of the edge.

Abstract: REMOVAL OF GASEOUS FORMALDEHYDE     WITH SOLID ABSORBENTS     Abstract Formaldehyde is used on large scale in chemical industry and it is incorporated in many resin products which are extensively used by the building industry and public. Since formaldehyde has recently been identified as a carcinogenic agent, proper protection against its inhalation is required for occupational personnel and some members of public. Some systems were developed for the remo-val of gaseous formaldehyde in industrial use, however no suitable system has been available for removing formaldehyde from breathing air at very low concentrations.         In this invention the process of chemisorption is employed to transfer gaseous formaldehyde to solid, nonvolatile compounds and retain it within the absorber. The absorbers, which can be produced in different forms of a filter, are suitable for occupa-tional respiratory protection, atmosphere purification in working and living areas and for formaldehyde absorption from process gases. The absorbents can also preventively be incorporated into resins containing materials to reduce formaldehyde emissions.

Abstract: ABSTRACT OF THE DISCLOSURE          When a plurality of shunt motors connected in paral-lel are used for driving an electric railcar, any difference in the characteristics of the motors introduced through the manufacturing steps causes the armature currents to become greatly different even when the motors are running at the same speed.  To control the field current by a single device, therefore, the armature currents must he corrected by armature choppers.  In order to fully recover the energy possessed by the electric railcar, the present invention automatically corrects difference in the characteristics of the shunt motors so that the required braking force is uniformly born by each of the shunt motors.

Abstract: ABSTRACT           A fluid motor (10) having a housing (12) with first (14), second (16) and third (18) chambers therein.  A first partition (22) separates the first chamber (14) from the second chamber (16).  A second partition (24) separates the second chamber (16) from the third chamber (18).  The third chamber (18) is connected to a source of fluid under pressure.  A valve mechanism (91) controls the communication of the source of fluid between the second )16) and third (18) chambers.  A poppet valve (42) allows the first fluid to flow into the first chamber (14) from the second chamber (16).  The first chamber (14) is connected to the third chamber (18) through a check valve (18).  The valve mechanism (91) responds to an operator input signal by terminating fluid communication between the second (16) and third (18) chambers and initiating communication of the second chamber (16) with air to create a pressure differential across the first (22) and second (24) partition (22) stationary but acts on the second partition (24) to develop an output force correspond-ing to the input signal.  Should the source of fluid be interrupted, the stored fluid in chamber (14) flows into chamber (18) to assure for the development of the operational pressure differential.

The smoothing capacitor is charged by current flowing from the inductor during a relaxation phase, to a voltage higher than the peaks of the rectifier.  The smoothing capacitor voltage is maintained by proportioning the control capacitor size to cause rectifier current, and not smoothing capacitor discharge, to supply circuit and load losses.
