Patent EP-0366903-A2 (EP)
Inventor: BRULHART PAUL
IPC: B01D29/46
Filed: 1989-09-06
Abstract: The filter spray head (1) is equipped with ring-shaped filter segments. These filter segments define both radial flow paths (28) and flow paths (26) which pass through the filter segments (18), which serve to guide filter liquid. These passages (26) through the filter segments (18) are constructed as passages (26) which narrow in the flow direction of the filtered water and are distributed evenly over the segment (18). The segments (18) exhibit stops which ensure that the passages (26) of two adjacent segments are not aligned. With such a filter spray head the risk of blockages is less than in the case of known spray heads. The former thus ensures a more regular operation and requires less frequent cleaning.

Abstract: In order to perform voice-switched telephoning, a hands-free telephone includes a speaker, a microphone, a receive variable attenuator (R-ATT), a transmit variable attenuator (T-ATT), a receive signal detector, a transmit signal detector and an attenuation control circuit. The telephone also includes an auxiliary control circuit which prevents the output of the transmit signal detector from reaching the attenuation control circuit during a transient period between a call origination and the beginning of conversation. During the transient period, only the speaker is enabled to output a ringback tone therethrough. When the output level of the transmit signal detector exceeds a predetermined level, the auxiliary control circuit passes the output of the transmit signal detector to the attenuation control circuit to start the voice-switched telephoning. Once the auxiliary control circuit passes the output of the transmit signal detector, it holds this state until the conversation finishes.

Abstract: The present invention provides a laminate construction including a backing sheet (18), which may be in the form of a continuous web, and a face sheet (12) covering at least a portion of the backing sheet. A releasable adhesive (16) secures a first or lower surface (13) of the face sheet (12) to a first or upper surface (17) of the backing sheet (18) such that the face sheet and backing sheet are readily separable. The releasable adhesive (16) contains therein a first composition (22) which, when subjected to an imaging force, forms a latent image (28, 30) on both of the first surfaces of the face and backing sheets. This latent image may be developed at a later time by contacting the image with a second composition which, when exposed to the first composition, forms a visible image. In the laminate, the face sheet (12) may be imprinted with legible and/or covert information. The covert information may be duplicated on the underside of the face sheet or on one or more intermediate sheets as well as a backing sheet. The face sheet can then be readily peeled from the construction and be used as a label, tag, form, or the like. The underlying sheets retain the same information as the face sheet. The covert or latent information can be developed at a later time to produce a visible image. All elements of the construction have nontacky surfaces, permitting easy handling and storage.

Abstract: Between the European plesiochronous digital signal hierarchy and the synchronous digital multiplex hierarchy, a standardised link is missing via several of which four 34.368-Mbit/s signals can be inserted into a synchronous transport module  STM-1. A synchronous transport module STM-0 having 135 columns (Sp) and 9 rows (Z) is proposed for a repetition rate of 4 kHz and a transmission capacity of 38.88 Mbit/s, which, in addition to an overhead (SOH, DZA) having three columns and two further columns (SG) for in-house signals, exhibits two user-information blocks (AU-31/1, AU-31/2) having in each case 65 columns. Apart from one standardised virtual container and one already proposed, a further virtual container suitable for insertion into these user-information blocks (AU-31/1, AU-31/2) is specified which can be transferred from there in a simple manner into a standardised synchronous transport module STM-1 of the next-higher hierarchy level. Furthermore, proposals are made for placing the data pointers. The synchronous transport module STM-0 is recommended as lowest level in the synchronous digital multiplex hierarchy. <IMAGE>

Abstract: A method for electronically detecting when a solenoid has closed, or nearly closed, indirectly senses changes in the inductance of the solenoid's coil as the solenoid closes. When the inductance has changed by a selected amount, the solenoid is assumed to have closed, or nearly closed, and current through the coil is promptly reduced. Preferably, changes in the inductance of the coil are sensed by establishing a plurality of current peaks in the coil, and sensing the current's decay time between peaks. When the decay time of a measured current peak exceeds the decay time of a previously measured current peak by a selected amount, it is assumed that the solenoid has closed, or nearly closed.

Abstract: An apparatus for generating clock signals for reproducing data and an apparatus for reproducing data are disclosed. With the apparatus for generating clock signals, reference clock signals actually recorded on a recording medium are sampled (10, 16) by using (11, 12) a number of outside clock signals having respectively different phases to find the maximum value of the differences of the sampling values sampled by the outside clock signals, and the outside clock signal associated with the maximum value is used as data-reproducing clock signal. With the apparatus for reproducing data, the outside clock signal associated with the maximum value is used as the data-reproducing clock signal, while the reproduced data signals are sampled with the outside clock signals, and the difference of these sampling values is compared to about one-half the maximum value of the sampling values of reproduced signals of said reference clock signals to perform data reproduction with a high noise margin.

Abstract: This invention provides a method and the apparatus for producing human autologous collagen from the human fat tissues and specifically for a method of disintegrating fat cells using ultrasonic energy and separating fats, blood, water and serum from the collagen, all of which can be accomplished without removing material from the harvesting syringe. The purpose of the invention is to produce autologous collagen which is useful in several cosmetic procedures used to treat all the problems caused by ageing. In accordance with the procedure taught in the invention after fat cells have been removed from the subject in a harvesting syringe, first the material in the syringe is subjected to an ultrasonic energy source of a range between 20 kHz and 3mHz which destroys the fat cells by rupturing them which allows the oil in the fat cells to be separated from the residual cell walls, after which the harvesting syringe is placed in a specially designed centrifuge allowing for the blood, serum, fat cell oil and collagen to be completely separated. In the fat cell disintegration step, when applying ultrasonic energy, two alternative devices may be employed with the harvesting syringe containing the material. In one, the syringes are placed in a container filled with a cold liquid and subjected to ultrasonic energy. The second, preferred method utilizes a high intensity ultrasonic processor that includes a probe that can be placed in the harvesting syringe that is mounted individually in a metal support filled with a cold liquid. In the separation stage, a multi- bodied centrifuge is provided which holds up to four harvesting syringes safely while subjected to centrifugal action to permit the separation of the materials as described herein. With the use of the present invention human autologous collagen can be produced in minutes without removal from the harvesting syringe for use in the operation at the time or for frozen storage in an individual patient collagen bank.
