Patent EP-0361260-A2 (EP)
Inventor: OPHARDT HERMANN
IPC: A47K5/12
Filed: 1989-09-18
Abstract: A piston pump for dosing flowable substances, for example disinfectant, liquid soaps or creams, has a permanently spring-loaded piston (1) which has a radial groove (2) in which an axially displaceable annular valve element (3) is arranged. In the rest position of the piston (1), the annular valve element (3) is pressed with the aid of the return spring (15) against a circumferential stop ring (6) arranged in the cylinder. By virtue of this arrangement, fluid-tight sealing of the pump is achieved, thus preventing afterdribble in an effective way. <IMAGE>

Abstract: In the field of high speed digital computers it is common for the computer to be interfaced to a plurality of input/output (I/O) units. These I/O units allow the computer to interact with the external world and are typically purchased as off-the-shelf units. As the capabilities and speed of computers increase, so too must the rate of data transfer between the computer and its I/O units. This increased rate of transfer is effected without altering the physical connection to the I/O units by an interface having a transmitter (24) and a receiver (26) wherein the transmitter includes a counter which keeps track of the condition of a buffer in the receiver. The counter maintains a record of the number of packets of data sent to the receiver and the amount of remaining free buffer space. In this manner, the transmitter is free to continuously send data without waiting for permission to do so from the receiver.

Abstract: Herein disclosed is a retractable wiper device which comprises: a first crank (2) connected for forward and backward rotations to the reduction output shaft (1) of a motor; and a second crank (3) rotatably supported on the first crank (2) such that it is kept in association at a predetermined bent angle with the first crank (2), while the first crank (2) is being rotated forward, and in general association with the first crank (2) while the first crank (2) is being rotated backward. When in the forward rotation of the first crank (2), a stopper (42) is al­ways pushed to keep its engagement with the first crank (2) thereby maintaining the aforementioned predeter­mined bent angle by two overlapped cams (40,41) which are as­sociated with each other at a predetermined play angle. When in the backward rotation of the first crank (2), on the other hand, the push of the stopper (42) by the two cams (40,41) is released in the vicinity of the top turn position of a wiper blade (14), and the portion of the stopper (42) in the vicinity of the pushed portion by the cams (40,41) is relieved in the forward direction of the first crank (2). As a result, the first and second cranks (2,3) are generally linear in the vicinity of the top turn posi­tion of the wiper blade.

Abstract: In a radar system using a long pulse containing a modulated signal, the received signal is converted to a short pulse by circuitry including means (103) for generating weight coefficients, delay means (7) for delaying the weight coefficients so as to generate N weight coefficients differing in delay time and N arithmetic means (116,126,...,1N6) which receive a common input signal having the form of time series data sampled in a prescribed sampling period. The arithmetic means (116) multiply the input signal by the received weight coefficients and then add the multiplication results up to the prescribed number. The outputs from the arithmetic means (116) are added by adding circuit (107) to produce a compressed signal corresponding to the short pulse.

Abstract: A bar code is used to identify a traveler's luggage, permitting the luggage to be tracked and, if desired, to be delivered to the traveler's ultimate destination (e.g., a hotel). If the traveler is traveling on an airline, a corresponding bar code is applied to the traveler's boarding pass. A bar code reader is used to read the boarding-pass bar code of each emplaning passenger; comparison of these bar codes with luggage bar-code data permits an alarm to be raised if each item of checked luggage is not matched by an emplaned passenger. The boarding-pass bar code may take the form of an integrated passenger identification code for use by, e.g., rental car companies, hotels, and the like.
