Title: Apparatus for dividing and grouping articles approaching line-by-line, one behind the other
Inventor: BRUDER HARALD R
IPC: B65G47/31
Filed: 1986-11-06
Abstract: In known grouping stations, the advance of the partitioning fingers is generated by means of a drive shaft which is arranged parallel to the conveying plane of the continuous conveyor. The drive shaft is connected to the distributors via spokes which are mounted securely on the drive shaft and longitudinally displaceably on the partitioners. The invention is intended to provide a kinematic, simply constructed apparatus for dividing groups of articles. The abovementioned object is achieved in that one or more rotating dividing finger wheels are mounted so as to be able, at high speed and below the dividing section, shortly before they emerge, to be laid against a retaining and dividing chain, which rotates at a lower speed, and then driven by the latter and at the same time separate at high speed from their retaining own drive system and subsequently detach themselves from the retaining and dividing chains, by the latter dropping away, and are conveyed further at a further increased speed. These apparatuses are used in particular in the packaging industry. <IMAGE>

Title: Circuit arrangement for the digital calibration of radio-frequency oscillators
Inventor: KIESELSTEIN DIRK
IPC: G04G3/02
Filed: 1986-12-22
Abstract: The invention relates to a circuit arrangement for calibrating an oscillator by means of an adjustable frequency divider 3-8, following the latter, the output frequency of which can be adjusted in steps at calibration connections by means of digital signals. The adjustable frequency divider (3-8) can be newly adjusted to a predeterminable value of stepping-down by any edge of the output signal of the circuit arrangement which extends in a predeterminable direction. Furthermore, the adjustable frequency divider 3-8 is followed by a control element 9, 10 which can be a first or second state set to which, in the first state and to which it is continuously set at an oscillator frequency below the nominal frequency, is transparent to the output signals of the adjustable frequency divider 3 to 8. In the second state, to which it can be set by any edge of the signal extending in a particular direction at the output of the circuit arrangement at an oscillator frequency above the nominal frequency, the control element 9, 10 can be set to the first state by an edge of the output signal of the adjustable frequency divider 3 to 8 extending in a predeterminable direction whilst blocking the forwarding of the edge. <IMAGE>

Patent DE-3705577-A1 (DE)
Inventor: DONHAUSER BERNHARD DIPL ING
IPC: G06F9/46
Filed: 1987-02-21
Abstract: A process for priority-dependent processing of various requests (INT1, INT2, INTX) of a computer, in which the requests are assigned a priority label corresponding to their degree of priority and are ranked in corresponding positions in a queue. It is particularly advantageous to divide the requests (INTX) into segments, which may have different priorities, so that particularly time-critical segments (INTX) can be processed immediately and non-critical segments (INTXI) can be processed later. By co-ordinating the priority labels, it is possible to organize the processing of different requests to suit the prevailing peripheral conditions to ensure optimal processing by the computer.

Title: Remotely controllable device for connecting pipe flanges
Inventor: SCHWALBACH MANFRED DIPL ING
IPC: F16L23/04
Filed: 1987-09-23
Abstract: In order to connect two pipe ends by the axial bracing of a fixed flange with a loose flange by means of radially braceable members, which, by running onto the rear oblique surfaces of the flanges, exert an axial pressure thereon, the invention proposes a remotely controllable device, in the case of which a bottom shell is connected to the fixed flange and a top shell and a bracing device are connected to the loose flange. By turning a single screw-bolt, bottom and top shells can be moved, radially with respect to the pipe axis, towards one another, and a pressing-on force acting axially on the flanges can thus be produced.

Title: Method of measuring the exhaust gas composition of internal combustion engines
Inventor: PARRER GERHARD
IPC: G01N1/22
Filed: 1987-09-30
Abstract: To measure the exhaust gas in the dynamic behaviour of a motor during the acceleration phase, a sample is taken from the exhaust gas (AG) of a single working stroke of a cylinder. For this purpose, a sampling device is attached to an exhaust pipe (AR) as close as possible to the outlet of the combustion chamber. The sampling device comprises a holding cylinder (HZ) and a sampling piston (EK) which can be moved therein in the longitudinal direction. The sampling piston (EK) is pushed out into the exhaust pipe (AR) and at the end pushed out has a drilled hole to fix a sampling volume (EV). By drawing back the sampling piston (EK), the sampling volume (EV) is closed by the holding cylinder (HZ). The exhaust gas sample is brought by a carrier gas (TG) via a transport capillary (TKL) to a gas chromatograph. For this purpose, the sampling volume (EV) in the drawn-back position of the sampling piston (EK) is flushed by the carrier gas (TG). To ensure sampling from a single working stroke, even at motor revolutions of 6000 rpm, a drawing device (ZV) has to draw the sampling piston (EK) back out of the exhaust pipe (AR) within 20 ms. The moment of closure of the sampling volume (EV) is determined by a marking sensor (MA) on a measuring pin (MZ) connected to the sampling piston (EK) and is stored in memory with the corresponding operating data of the motor for evaluation. <IMAGE>

Title: Long-stroke eccentric press
Inventor: KLASCHKA RUDOLF
IPC: B30B1/26
Filed: 1987-10-27
Abstract: The long-stroke eccentric press, which is provided with a connecting rod 7 which takes the form of a knee lever and transmits power, operates at extremely low levels of noise and vibration. The yielding movement of the power-transmitting connecting rod 7 has already been completed when the eccentric flywheel 3 has completed half a rotation, so that the pressing power only comes into action at the slow advancing speed of the eccentric drive. This is achieved by means of a control device for the yielding movement, which device is composed of an eccentrically positioned control connecting rod 12, a guide device 14 and a fixing device 15 for the said control connecting rod, the control device being coupled, at a transmission ratio which is greater than 1:1, to the eccentric drive of the power-transmitting connecting rod 7. <IMAGE>
