Abstract: Abstract of the Disclosure A process is described for the production of high yields of lead chromate-containing pigments in a nondusting granular form. The process involves agitating in aqueous medium designated amounts of lead chromate-containing pigment, a friable, low molecular weight hydrocarbon-type resin softening at 50-95°C. and a cationic surfactant at a temperature above the softening point of the resin and continuing agitation at a temperature within the range of about 5 to about 20°C. above the softening point of the resin until the pigment dispersion is granulated. The process provides yields of at least 70% of granules in the particle size range of about 0.1 to about 4 millimeters. The granules are particularly useful as colorants for air-drying enamel coating systems and plastics.

Abstract: ABSTRACT      The invention refers to a device with which provisional consolidating frames adapted to be brought to a smaller size can be transported to the drift face and can be put in place. According to the invention this device is arranged on the cutting machine itself so that the narrow space remaining between the contour of the emtting machine and the cross section of the drift is sufficient for transporting in forward direction and putting in place the provisional consolidating frames without the necessity to retract the face advancement machine from the ddrift face. Thus, face advancement machines can be used which occupy the major part of the inside width of the drift, noting that the face advancing machine is maintained in its working position.  The invention further describes a door-jamb frame for the provisional drift consolidation and which is particularly suitable for the device proposed.

Abstract: TITLE:  TOY MUSICAL INSTRUMENT     ABSTRACT          A musical instrument is disclosed which is capable of being operated in either of two different ways--through the use of a rotary record member, or through the manual manipulation of individual keys.  The instrument disclosed includes a windchest used to supply air to either of two different principal valves, each of which is capable of being manipulated so as to set up resonance within an associated resonance chamber.  Secon-dary valves are provided for varying the acoustically effective dimensions of the resonating chambers.  All of the valves have actuators which extend into an area of the instrument capable of serving as a holder for the record member.  When the record member is inserted in this holder and rotated cams on the record member engage the actuators so as to cause the production of a desired series of notes.  Keys on the instrument are capable of being manually manipulated so as to cause the movement of levers into engagement with the actuators when to record member is present.

Abstract: ABSTRACT OF THE DISCLOSURE:           A keyboard type telephone station connected to a telephone subscriber's line comprises a dial pulse train generator and a dialling multifrequency signal generator.          The telephone station includes detecting means which comprises at least one threshold detector for the power level of supervisory or so-called tone signals.  Each supervisory signal is transmitted from the linking exchange on the telephone subscriber's line and indicates the beginning of a dialling phase in setting up a telephone communication.  In response to the detection of the supervisory signal, the detecting means controls means for blocking transmission of the pulse generator and for releasing transmission of the multifrequency generator, so that only the multifrequency generator transmits only the dialling multifrequency signal associated with the first key of the dialling phase.  Then the detecting means controls automatically the blocking and releasing means such that only the pulse generator transmits the dial pulse trains associated with said first key and with the subsequent keys of the dialling phase in response to further detection of the supervisory signal, or such that only the multifrequency generator transmits the dialling multifrequency signals associated only with the said subsequent keys in response to the non-detection of the supervisory signal.

Abstract: ABSTRACT A circuit arrangment for the formation of periodic pulse patterns for use in controlling converters which is capable of quick change of circuit arrangement without time wasted in adjustment and capable of use in different applications without need to change circuit.  The circuit arrangement of the invention is also useful for the formation of a periodic pulse pattern which is variable as a function of a control signal.  For this purpose the desired pulse pattern is formed of auxiliary patterns stored in a number of memories. An oscillator drives a binary-coded counter which forms the addresses for a memory in which the desired pulse pattern is stored.  The address inputs of at least one of these memories are connected to the output of the counter by means of an arrangement for address shifting which responds to a control signal.

Abstract: ABSTRACT OF THE DISCLOSURE         A distributed charge for use in producing a very sharp impulse for seismic prospecting comprises a series of lump explosive charges placed preferably of the order of at least 20 feet apart in a fluid in a well, connected with novel timed fuses.  These fuses are each made of a short top section of a small diameter detonating linear explosive and a considerably longer, lower section which is a non-detonating linear deflagrator, terminating in a blasting cap inserted in the next lower lump explosive charge.  The lower section is in the form of a thin-walled plastic tube lined with the active chemical agent.  It may be crumpled or bent into various shapes including cross-overs without serious problems of disconnection or prema-ture initiation.  Accordingly, axial length of each such fuse may be considerably more than the physical distance between the lump explosive charges.

Abstract: 19.9.1979                                      PHD 78-148 ABSTRACT: "Aperture system for radiation sources situated in parallel planes".     Aperture plates comprising fixed apertures are suitable to only a limited degree for multiple radiation sources. In order to enable stopping of the radiation beams of a multiple radiation source to the size of an object zone to be examined, use is made of aperture systems com-prising aperture plates which are displaceable parallel to each other. The aperture plates comprise passages whose dis-tribution corresponds to the distribution of the radiation souces. By lateral parallel displacement of the aperture plates, the passages are shifted with respect to each other, so that the passage can be adjusted.Continuously,adjustable apertures can thus be realized. When the radiation sources are situated in different mutually parallel planes, a group of aperture plates must be associated with each plane for continuous stopping of the radiation beams by means of the aperture plates. The dimensions of the passages of the aper-ture plates are then each time dependent of the position of the aperture plates in the beam path of the multiple radia-tion source.
