Title: Pipe disconnector
Inventor: KAHLE KARL-JOSEF
IPC: E03C1/10
Filed: 1986-08-02
Abstract: In order to improve a pipe disconnector such that it is only in the through-passage position when water is consumed, a multi-way valve (3) is arranged upstream of it and a non-return valve (4) is arranged downstream of it. Furthermore, the multi-way valve has one through-passage connecting the pipe disconnector to the drinking-water supply line and one through-passage connecting to the draining line (7). Arranged behind the valve body (9) of the non-return valve (4) is a pressure switch (13) which can be actuated by the water pressure and effects the changeover of the multi-way valve (3) into either of the through-passage positions. There is further provided a second non-return valve (14), which can be actuated by the non-return valve (4) and opens in the throughflow direction of the drinking water. Moreover, there is arranged, upstream of the pressure switch (13), a shut-off member (12) which can be actuated by the first non-return valve (4) and which releases the through-passage to the pressure switch (13) after the first non-return valve (4) has closed or which closes before the first non-return valve (4) has opened. <IMAGE>

Title: Circuit arrangement for a self-oscillating, transistorised and no-load-protected push-pull-type ultrasonic generator
Inventor: LUEDTKE KURT
IPC: B29C65/00
Filed: 1986-10-09
Abstract: The present invention relates to a circuit arrangement for a self-oscillating, transistorised and no-load-protected push-pull-type ultrasonic generator for generating ultrasonic oscillations with starting circuit by means of a resistor and diode, in which the feedback signal is obtained from the load current and which is operated with a pulsating direct voltage. It is the object of the invention to create a circuit arrangement for ultrasonic generators of the said type, the use of which results in considerable improvement in the efficiency of the ultrasonic generators. The object is achieved with the aid of a circuit arrangement in which the collector lines of the power transistors are coupled to a saturated current transformer and the no-load-protection of the ultrasonic generator is ensured by a series resistor in the positive feedline of the operating voltage, due to the fact that the ultrasonic generator is always under no-load voltage. This circuit arrangement results in an economic use of ultrasonic technology, mainly in the packaging industry, due to an operationally reliable, self-oscillating push-pull-type ultrasonic generator which is simple and thus inexpensive to produce.

Title: Refuse bin opener with pedal actuation
Inventor: DOERR WILHELM ING GRAD
IPC: B65F1/16
Filed: 1987-02-09
Abstract: The title is "Refuse bin opener with pedal actuation", my Patent No. 3313309.3. This patent is to be used for rectangular plastic bins of 240 litres capacity. Since, however, there are also cylindrical sheet metal bins of about 150 litres capacity, a special lever mechanism has been developed to enable these bins, too, to be designed in a user-friendly manner. This lever mechanism can be mounted without great difficulty on the bin, which is concreted in by its feet. The junction plate with the lever arms is screwed with only 2 existing screws between the concreted-in foot and the sheet metal bin. The lid-lifter is only pushed in between the lid and lid hinge and lid handle and bends around a lug. Hence also immediately protected against theft. When the foot pedal is actuated, the lid is now lifted via a lever arm with an articulated and angled iron T-bar which is articulated on the lid-lifter. Closing takes place as a result of its intrinsic weight.

Abstract: PCT No. PCT/DE88/00440 Sec. 371 Date Jan. 29, 1990 Sec. 102(e) Date Jan. 29, 1990 PCT Filed Jul. 16, 1988 PCT Pub. No. WO89/01083 PCT Pub. Date Feb. 9, 1989.A form for the pouring of concrete has first and second panels which are disposed edge-to-edge. Each of the panels has a flange projecting from the major surface of the respective panel and the flanges have confronting first surfaces which are perpendicular to the major surfaces of the panels and are designed to abut one another. The flanges have second surfaces which face away from the first surfaces and the second surfaces are inclined to the major surfaces of the panels so that the flanges narrow in a direction away from the panels. A clamping element designed to embrace the flanges is pivotally mounted on the first panel and is movable between a released position and a clamping position in which it embraces the flanges. The second panel carries an abutment and the clamping element has a free end which is located between the abutment and the flange of the second panel in the clamping position. A wedge-like slide is mounted on the free end of the clamping element for movement between a retracted position and an extended position. The arrangement is such that, when the clamping element is in its clamping position and the slide is moved to its extended position, the slide pushes against the abutment thereby causing the clamping element to urge the flanges into engagement with one another.
