Title: Hollow y-piece for infusion apparatuses
IPC: A61M5/14
Filed: 1988-01-29
Granted: 1991-06-05
Abstract: The hollow Y-piece for infusion apparatuses has an inlet channel 3 for the infusion solution and an injection channel 5, with injection plug 2, for the injection of medicaments, and a common outlet channel. In the one embodiment, the inlet channel 3 is connected, via a diversion channel 4 extending parallel to the injection channel 5, to the area of the injection channel adjacent to the injection plug. In the other embodiment, a throttle position is provided in the area of the point of entry of the inlet channel 3 into the injection channel 5, and the area of the injection channel adjacent to the injection plug 2 is connected via a diversion channel to the injection channel downstream of the throttle position. In the one embodiment, there is a diversion whereas, in the other embodiment, a partial vacuum is produced in the injection channel upstream of the point of entry of the inlet channel. In both cases, it is ensured that no residual air cushions can form in the area of the injection plug, i.e. in the injection canal, since, upon the initial filling, an appropriate flow is ensured. Dangerous air inclusions are in this way prevented.

Filed: 1988-09-19
Granted: 1992-04-22
Abstract: A method for temperature control of the heating medium of a closed loop heating system operated with a burner envisages that this control is carried out depending upon both the actual temperature of the heating medium and the outside temperature, and more particularly both by control of the burner capacity and by control of the circulating speed of the heating medium, the control of the circulating speed of the heating medium being started preferably only when a predetermined minimum temperature of the heating medium is reached. A device which is suitable for implementing the method comprises a control (6), to which are connected both an outside temperature sensor (7) and a temperature sensor (12) arranged in the forward run (10) of the closed loop heating system (10, 11), and which can control both the fuel supply to the burner (1) of the heat exchanger (2) via a fuel supply valve (3) and also the speed of the circulating pump (9) depending upon the temperatures measured.

Inventor: HILBERT STEPHAN
IPC: H04N11/08
Filed: 1989-07-11
Granted: 1994-03-02
Abstract: The invention relates to a circuit for recognising whole-picture frames of C, D and D2-MAC packet signals for generating whole-picture frame-synchronous pulses, particularly clamping pulses for clamping amplifiers in satellite receiving systems. To make such a circuit cost-effective, and at the same time ensure an operation without problems, it is proposed according to the invention to evaluate not, as is known, the line synchronisation words and the frame-synchronisation word but the white and black signal of reference line 624 and the frame-synchronisation sequence transmitted in line 625. For this purpose, the baseband signal is supplied to a reference line detection circuit (RZE) for detecting the white and the black reference signal (SW, SS) which, when the reference line is detected, emits an enable signal, and on the other hand, directly to a frame synchronisation sequence detection circuit (RSE) in which it is logically combined with the enable signal by means of an AND gate (UG2), the output of which is connected to the input of a counter (Z) which supplies whole-picture frame-synchronous pulses at the output (A). <IMAGE>

Inventor: BERGER HERMANN
IPC: G01F1/20
Filed: 1989-07-25
Granted: 1994-06-08
Abstract: The upwardly extending outlet of a pump contains a non-floating permanent magnet which tends to assume a lower end position but is propelled upwardly in response to admission of a metered quantity of liquid into the outlet to initiate the emission of a signal by a sensor. The emission of such signal persists as long as the actuator remains above its lower end position. The sensor is connected with the resetting input of a counter by way of an OR circuit. The n-th output of the counter transmits a signal to an alarm signal generating circuit in response to transmission of a certain number of consective timing pulses to its counting input prior to transmission of a signal to the resetting input. The timing pulses are transmitted by a generator which also transmits pulses to the pump to thus determine the frequency of admission of liquid into the outlet. A rectangular wave oscillator receives signals from the sensor and transmits a series of signals to the OR circuit with a delay which equals or approximates the length of the interval between two consecutive timing pulses. The oscillator starts to transmit signals to the OR circuit only if the signal which is emitted by the sensor persists during the aforementioned delay. This ensures that no alarm signal is generated if the viscosity of pumped liquid is so high that the actuator is incapable of returning to its lower end position during the interval between successive admissions of liquid into the outlet.

Title: Process for the transfer of material to a support, apparatus for carrying out the process and use of this apparatus
IPC: D06Q1/14
Filed: 1989-01-09
Granted: 1992-10-07
Abstract: In order to make it possible to transfer flocky material (1) in particular zones onto a web-like support (2) moving forwards, the flocky material (1) is fed in a metered manner onto a transfer band (12) made air-permeable in particular zones according to the desired transfer pattern (11). On this transfer band, the flocky material is retained on the air-permeable band zones by means of a vacuum acting on the underside of this. The flocks located on the transfer band (12) outside these air-permeable band zones are then removed from the surface of the transfer band. The region of the transfer band (12) which still bears the flocks and which corresponds to the desired transfer pattern is subsequently brought into coincidence with the web-like support (2) to be coated in particular zones. These flocks are thereupon deposited onto the web-like support (2) to be coated in particular zones, the vacuum acting on them being cancelled. <IMAGE>

Abstract: The prosthesis stem is provided with a recess on each side having boundary walls concentric to a common center of curvature. Each recess receives a molding which carries a wire mesh structure for the invasion of bone tissue after implantation. Bending of the proximal zone of the stem occurs without movement of the molding so that shear stresses are not imposed upon the bone tissue invading the wire mesh. A peg-like projection on each molding fits with a clearance in a further recess in the metal stem to avoid accidential sliding out of each recess.

Abstract: L'unité ci-décrite est destinée à effectuer de manière fiable différents types de commandes indiquées pour un travail déterminé, uniquement en appuyant sur une plage de symbole correspondant (21) (fig. 3), afin de sélectionner le type de travail que l'engin doit exécuter, de manière à éliminer la tâche fastidieuse consistant à actionner un grand nombre de commutateurs pour modifier les commandes lors du changement du type de travail, et à empêcher l'actionnement erroné des commutateurs de commande. Lorsqu'on sélectionne un mode de travail sur une console de commande (OP) (fig. 1), un signal représentant le mode de travail sélectionné est envoyé à un organe de commande de pompe (30). L'organe de commande de pompe (30) envoie un signal représentant le nombre de tours du moteur (33) indiqué pour le mode de travail sélectionné et un signal représentant le niveau d'un couple  d'absorption combiné des pompes (31, 32) à un régulateur électrique (60) et à une soupape TVC (51), respectivement. Un régulateur (62) et des plateaux inclinés (31a), (32a) des pompes (31), (32) respectivement sont commandés ensuite de sorte que le régime du moteur (33) atteigne le nombre de tours requis et que le couple de sortie du moteur (33) corresponde au couple d'absorption combiné. L'organe de commande de pompe (30) envoie un signal de mise sous tension à un solénoïde (39) entre un levier d'actionnement (38a) et une soupape d'actionnement (37) et envoie un signal de décélération à un régulateur électrique (60) en réponse au mode de travail sélectionné. Lorsque le signal de mise sous tension est envoyé au solénoïde (39), la pression d'huile de décharge de l'une des pompes (32) n'est pas appliquée à un cylindre (41). Lorsque le signal de décélération est envoyé au régulateur électrique (60), celui-ci réduit le régime du moteur au nombre de tours fixé d'avance lorsque le levier d'actionnement (38a) est au point mort. L'unité de commande ci-décrite est utilisée principalement dans des engins de construction, tels que des pelles mécaniques.
