Title: Electronic taximeter with fare charged by distance or time taken - has two counters for respective modes coupled via gating logic and operates on accumulated numerical valve
Inventor: TATEISHI IWAO
IPC: G07B13/00
Filed: 1980-01-10
Abstract: The taximeter has a first counter (11) which records the time interval between successive distance pulses (5) to determine whether the fare is charged in dependence on the travelled distance or the time taken. A second counter (18) is used when the charged fare is dependent on the time taken and stores an accumulated numerical value (N) corresponding to the count values between successive distance pulses (S) recorded by the first counter (11), the fare being calculated in dependence on the resulting count ratio of the second counter. Pref. the first counter (11) receives pulses (CP) at a given frequency and when a given count value is obtained before the counter is reset by the following distance pulse (S) a logic network (13, 15, 17) allows the count values to be forwarded to the second counter (18).

Title: Load modulated brake control - has control valve coupled to rod responsive to individual suspension movement by sliding links
Inventor: KRONIGER WILHELM
IPC: B60T8/24
Filed: 1980-06-12
Abstract: The load modulated hydraulic brake valve has a control rod (22) which operates on the valve in response to suspension movements to modulate the brake force during braking, cornering and under dynamic load change. The brake operates independently on each rear wheel and prevents slewing. The suspension movements are monitored by thrust rods (7,8) coupled to a control lever (11) pivoted on the chassis. The coupling to the lever is by slotted links (20,26) so that a set amount of suspension movement is allowed before modulation sets in.

Title: Method for checking the operation of a multiplexer in a three-computer system
Inventor: BUSCH ARMIN DIPL ING
IPC: G06F11/18
Filed: 1981-03-09
Abstract: To check the operability of a multiplexer (DA), it is supplied with predetermined test data and it is determined whether the multiplexer is capable of switching through both data bits of weight 1 and those of weight 0. In a multiplexer with three multiplexer switches (M1, M2, M3), this is done in two test phases with in each case three test steps in which in each case one multiplexer is occupied with one test datum whilst inverse data are supplied to the other multiplexers. These data are supplied by the computers (R1, R2, R3) of a three-computer system, the data of which are to be switched through by the multiplexers when not in test mode. By comparing the data output by the multiplexer switches in the individual test steps with the data expected by them in test mode, the computers also check whether the multiplexer switches are operating correctly or not. On the basis of the test results formed by them, they determine any disturbances in accordance with the type and location of the disturbance and respond to any disturbance by selectively switching over individual multiplexer switches or by disconnecting the feeding computer system. In the case of a computer disturbance, the computers which then still operate correctly handle the triggering of the response in question in each case. <IMAGE>

Title: Intermittently effective information transmission device with at least one response element and one interrogation element which is track-bound in relation to the latter
Inventor: ENGELMANN GUENTER ING GRAD
IPC: B61L25/04
Filed: 1981-03-25
Abstract: In order to position an interrogation element (AB) centrally with respect to one of a plurality of response elements, a start of passage and an end of passage criterion are determined for each response element by an evaluation circuit (A) from the quality of the signal received from the respective response element. The interval between these criteria is recorded for each response element in a memory (SP). If the interval for a response element to be actuated is known, positioning can thus take place in such a way that from the start of passage half the stored interval is taken into account. <IMAGE>

Filed: 1981-07-18
Abstract: The invention relates to a mixer, especially for tea, having a rotating mixing drum with a built-in dust removal nozzle, which sucks air containing dust from the mixing drum and blows dust-free air back into the mixing drum after cleaning. In order to improve the mixing effect, the inflow of cleaned air is open in a predefined region within the mixing drum. Some of the mixing material falls through this open region while the drum rotates, is carried along by the flow of air and released once again at another point within the mixing drum, at the outlet end of the dust removal nozzle. <IMAGE>

Title: Head rest (head restraint) device
Inventor: BECKER BURCKHARD ING GRAD
IPC: B60N2/48
Filed: 1981-08-10
Abstract: The invention relates to a head rest device of a backrest of a vehicle seat, having a supporting framework associated with the backrest and a support frame articulated on the supporting framework. This support frame can be folded into a folded-down position and into a supporting position in which a cushion of the support frame can support the head of a passenger. The swivelling spindle of the support frame is located under the upper edge of the seat. Furthermore, there is arranged, between the supporting framework and the support frame, a ratchet which has a ratchet wheel segment with saw-tooth-shaped teeth and a pawl. The latter is either in releasable engagement with the teeth of the ratchet wheel segment and prevents the support frame from folding down or it is normally not in engagement with the teeth of the ratchet wheel segment and automatically enters into engagement when the vehicle accelerates at a rate which lies above a threshold value. <IMAGE>

Title: Direct-current detector
Inventor: IWASAKI SHINICHIRO
IPC: G01R15/18
Filed: 1981-08-21
Abstract: A direct-current detector is specified which exhibits a current/pulse duty ratio transducer element having a core of an amorphous soft-magnetic material on which a first and a second winding are mounted. A current to be determined is conducted via the first winding whilst the current flowing through the second winding is detected. Pulses having a predetermined frequency are applied to one end of the second winding whilst the other end of the second winding is connected to an element which converts the current flowing via the second winding into a corresponding voltage. The voltage produced across the element is integrated and then converted into an analog voltage. The duty ratio of the voltage pulses occurring across the element connected to the other end of the second winding changes in accordance with the intensity of the current flowing via the first winding, which changes the analog voltage.
