Title: Protective cap for plug-on hose couplings
Inventor: KLEINE KARL HEINZ
IPC: B65D59/06
Filed: 1984-09-10
Abstract: Generally and in the known form, protective caps are fitted more or less firmly over a fitting part to be protected against soiling. If a protective cap has to be arranged securely against vibrations over a movable fitting part which is to remain unaffected by the holding force of the protective cap, a bottom sleeve is suitable for this purpose which is matched to the fitting, is offset in two steps, is clamped firmly on the coupling neck (12) with the clamping sleeve part (10) of smaller diameter and, with the part (6) of the protective cap of larger diameter, covers the knurled sliding sleeve (5) with little contact at the front part (2a). In contrast, the holding loop (13) is firmly connected to the sliding sleeve (5) for operational reasons. <IMAGE>

Title: Method for ultrasound flow measurement, and a circuit arrangement for carrying out the method
Inventor: NAKAGAWA YUKIO DIPL ING
IPC: G01F1/66
Filed: 1984-11-08
Abstract: In the case of the method according to the invention, the flow of a medium is determined with the aid of a difference frequency  DELTA f = f1 - f2. In this case, the frequency f1 is inversely proportional to the delay time of an ultrasound wave in the flow direction of the medium between two points. The frequency f2 is inversely proportional to the delay time of an ultrasound wave in the opposite direction to the flow direction, between the same points. In addition, a difference frequency  DELTA f0 = f01 - f02, when the medium is stationary, is determined in advance and is stored, the frequencies f01 and f02 corresponding to the frequencies f1 and f2 when the medium is stationary. Zero compensation using the variable  DELTA f0[(f1 + f2)/(f01 + f02)] is carried out for every measurement, with the aid of the difference frequency  DELTA f0 and the values f1, f2, f01, f02. <IMAGE>

Patent DE-3504397-A1 (DE)
Title: Apparatus for producing flowing screed
Inventor: WILDGRUBER HELMUT
IPC: B28C9/00
Filed: 1985-02-08
Abstract: A mixing machine which can be filled with ready-made dry mortar from a silo via a conveying means has a mixing container on which a water-metering means is connected and which is equipped with a level indicator which, when a predetermined level has been reached, stops the conveying means which supplies the ready-made dry mortar. As a result, even when the supply of ready-made dry mortar is not constant with respect to time and without complex weighing, the water/ready-made dry mortar value, which is decisive for the quality of the flowing screed, remains constant with a very low tolerance.

Title: Spacing and aerating element for ventilated roof structures
IPC: E04D13/17
Filed: 1985-04-15

Patent DE-3514149-A1 (DE)
Title: Magnetic key arrangement
Inventor: DLUHOSCH JOACHIM DIPL ING
IPC: G07C9/00
Filed: 1985-04-19
Abstract: The arrangement comprises a magnetic key (3) which has one behind another in its direction of insertion a plurality of permanently magnetic coding areas (17), which are arranged in an array having predetermined array spaces and which define a key code. The magnetic key (3) further has one behind another in the direction of insertion at the array spacing of the coding areas permanently magnetic clock-pulse areas (21), which are arranged with alternating direction of the magnetic field and define an item of clock-pulse information. A reading device scans the coding areas (17) and the clock-pulse areas (21) by means of magnetic-field sensors (19, 23) in a serial fashion. The clock-pulse areas (21) are mutually offset by half an array spacing in the direction (5) of insertion relative to the coding areas (17). The key code information is evaluated as a function of clock pulses which the reading device generates as a function of the minimum in the absolute value of the field strength between adjacent clock-pulse areas (21). Alternatively, the clock-pulse areas (21) can also be aligned relative to the coding areas (17) in the array, if instead the magnetic-field sensor (23) supplying the clock-pulse information is offset by half an array spacing with respect to the magnetic-field sensors (19) scanning the coding areas (17). In such a magnetic key arrangement, the key code of the magnetic key can be read serially using magnetic-field sensors of simple construction which, as the case may be, operate in an analog fashion.   <IMAGE>

Title: Method and circuit arrangement for transmitting data signals in time slots of a transmission line used in time division multiplexing
Inventor: HABERER HERBERT DIPL ING
IPC: H04J3/16
Filed: 1985-09-18
Abstract: To control the transmission of data signals in each case provided on transmission channels (UE1 to UEn) in time slots of a transmission line (Ltg) used in time division multiplexing, a bit string is defined for each of the transmission channels with a number of control bits permanently allocated to the time slots associated with a pulse frame which corresponds to the number of these time slots, through the occurrence of which control bits in a specific binary state the occupancy of the associated time slot is in each case displayed as a transmission time slot for the respective transmission channel within the pulse frame concerned. The control bits of the bit string in each case associated with the transmission channels are made available consecutively and in cyclically repeated fashion in consecutive pulse frames in the timing pattern of the time slots. Data signals provided on the transmission channel are forwarded to the transmission line only in those time slots which correspond to one another and which are marked as transmission time slots by the binary states of the allocated control bits. <IMAGE>

Patent DE-3607138-A1 (DE)
Title: Hydraulic system with a control device
Inventor: OLBRICH GOTTFRIED DIPL ING
IPC: F02D29/04
Filed: 1986-03-05
Abstract: The hydraulic system has a pump (10), driven, for example, by a diesel engine (13), which feeds hydraulic fluid to loads via directional control valves (22 to 24). The injection pump (14) of the diesel engine (13) is influenced with the aid of a pressure-actuated adjusting cylinder (15), on which the pressure produced in a control line (16) to raise the speed of the diesel engine acts. This pressure is prepared by the interaction of a control piston (96 to 98) and a pressure-regulating valve (41), these valves being influenced by the control pressure drop at the load. Only when more hydraulic fluid is required at the load is a corresponding adjustment of the pressure-regulating valve performed to increase the adjusting pressure, thereby in turn increasing the rotational speed of the pump. Since the sensor for the control pressure drop is designed as a separate piston (96 to 98), particularly good stability of the control circuit is achieved. <IMAGE>
