Patent DE-3029014-A1 (DE)
Title: Heat pump extracting heat from air or water - uses medium or other medium in liquid or vapour form to cool refrigerant
Inventor: SCHLEUSNER ULRICH
IPC: F25B30/02
Filed: 1980-07-31
Abstract: The heat pump which circulates a refrigerating medium which vapourises at a constant lower temp. to extract heat from a second medium such air or an underground water source, compresses the first medium in one or more compressors to extract useful heat. This first medium is cooled down by the second medium by using an additional heat exchanger. The temp. difference between them is at least 30 deg.K. In another system a further medium is used for the cooling operation. In a further system, the second medium in its vapourised form is used for the cooling operation using an additional heat exchanger.

Title: Sewage aeration system - by relative motion against revolving aerator with porous tubes producing fine bubbles
Inventor: ZINK JUERGEN
IPC: B01F7/00
Filed: 1980-09-15
Abstract: A liq. esp. sewage, is aerated by an immersed aerator with at least one tubular element with gas-permeable pores for the passage of air. During the aeration period, the liq. and/or the tubular element are moved in a direction transverse to the longitudinal axis. The relatively velocity between convex outside surface and contacting liquid is such (at least 50 cm/sec) that extremely fine air bubbles with a dia. of under 1 mm are severed by a shearing section. Such small bubbles rise slowly, resulting in a long residence time and better aeration intensity.

Patent DE-3041936-A1 (DE)
Inventor: MUELLER HEINRICH
IPC: A61F9/06
Filed: 1980-11-06
Abstract: In the case of electrical arc-welding work, in order to obtain protection against glare the viewing slot (49) in a protective screen (42) is covered by a filtering pane of glass (4) as soon as the electrode is placed on a workpiece. In order to prevent any incidence of light when the arc is struck, the thyristor which controls the welding current is not triggered, via a contact, until the filtering pane of glass (4) has reached a position covering the viewing slot (49). In order to match the filtering glasses to different arc intensities in a simple manner, replaceable cassettes (41) are provided which can be connected via a mechanical coupling (50) to the magnetic operating device (43) which is fixed to the protective screen. <IMAGE>

Title: Instantaneous ignition circuit for discharge lamp - briefly switches in second winding, inductively coupled to first winding
Inventor: BUSER JOHANN
IPC: H05B41/14
Filed: 1980-12-05
Abstract: The circuit has a main switch (8) for applying the a.c. supply voltage (U) to a first winding (6) and a second switch (10) connecting the output side of the main switch to one end of a second winding (9) inductively coupled to the first winding. The other end of the second winding is connected to one supply pole, i.e. to one electrode (3) of the discharge lamp (1). The other end of the first winding is connected to the other electrode (4) of the lamp. The first winding acts as a current limiter and forms a transformer with the second winding that transforms the supply voltage into a value that causes an arc discharge to develop immediately between the lamp's electrode. The second switch is opened again after a very short time, thereby disconnecting the second winding. The electrodes may have pot-shaped metal parts at their edges. The metal parts have discharge or emission points so that the arc is circular w.r.t. the walls of the lamp's tube, i.e. transverse w.r.t. the lamp's axis. The advantage lies in immediate ignition.

Between rails and clamps there is a block, preventing clamps from sliding in the opposite direction. The rail can have a serrated strip, and the clamp an inclined blocking lug (7), sliding over the serration and supported the other way against a tooth. Rails can be U-, T-, rectangular or trapezoid sectioned.

Title: DC pulse transformer
Inventor: DEPENBROCK MANFRED DR PROF
IPC: H02J7/02
Filed: 1981-02-12
Abstract: Five variants of a DC pulse transformer for charging a battery from an AC voltage power supply are proposed, it being possible for the peak value of the AC power supply voltage to be less than or greater than the voltage of the battery to be charged. The individual DC pulse transformer variants differ as a result of different combinations and series connections of known step-up controllers and step-down controllers. In the case of a basic variant, a first diode (D1) is arranged between a first input terminal (E1) and a first output terminal (A1). A capacitor (C1, C2) is in each case provided between the first and second input terminals (E1, E2) and between the first and second output terminals (A1, A2). The series circuit consisting of a power transistor (T2) (having a high switching frequency) and an inductor coil (L1/2) is connected between the second input terminal (E2) and the second output terminal (A2). The first input terminal (E1) and the second output terminal (A2) are connected to one another via a thyristor (Th1). A second diode (D2) is connected to the junction point between the transistor (T2) and the inductor coil (L1/2) and its other side is connected to the first output terminal (A1). <IMAGE>

IPC: G05D23/12
Filed: 1981-05-09
Abstract: In the case of the method and device for switching and regulating, in a thermally controlled and overheating-proof manner, an expansion tank (1) which is connected in a sealed manner to a container (5) via a pipe (3), a relative movement, and therefore a regulating force, is generated by modifying a volume in the expansion tank (1). At least one liquid medium (6) is used as a volume and after evacuation is at least partly fed into the expansion tank (1), the pipe (3) and the container (5), which components are connected to one another. In this process, the medium (6) is thermodynamically balanced in its liquid phase with the medium (6') in its gaseous phase. In this process, modification of the volume of the expansion tank (1) is brought about by the phase transition of the liquid medium (6) in the container (5) into its gaseous phase (6'). <IMAGE>

Title: Burner nozzle unit for combustion of a gas/air mixture
Inventor: BUEKER EMIL
IPC: F23D14/26
Filed: 1981-11-10
Abstract: A burner nozzle unit with a nozzle body and a nozzle jacket which encloses the nozzle body at a distance. The nozzle body has a central bore as main flame duct and several holding flame ducts which start from the main flame duct and surround it in a circular manner so that the holding flames keep the main flame burning and stabilise it. The holding flame ducts open at a circumferential cutout on the nozzle body, one side wall of which runs approximately at right angles to the longitudinal direction of the holding flame ducts. On the opposite side wall of the circumferential cutout, a ring is located on the nozzle body. Between the circumference of the ring and the inner wall of the nozzle material, there is a narrow gap which connects the inner space formed by the circumferential cutout to the free atmosphere. The longitudinal axes of the holding flame ducts are aligned on the ring which acts as a baffle when the gas/air mixture flows through. Moreover, homogenising swirling of the gas/air mixture takes place in the inner space.

IPC: H01H27/06
Filed: 1982-02-05
Abstract: In a key-operated switch, in which a cylinder lock and a rotary switch are arranged axially one behind the other in a housing, a cylindrical connecting piece consisting of an electrically insulating material is arranged between the cylinder lock and the rotary switch, which connecting piece is connected in a rotationally fixed manner at one end to the rotatable part of the cylinder lock and at the other end to the rotor of the rotary switch, and has a length which is adequate to give the key-operated switch a desired dielectric strength which reliably prevents electrostatic discharges being transmitted from the cylinder lock to the rotary switch and hence to the circuit connected thereto. At the same time, the connecting piece interacts with an inwardly projecting collar of the housing to form a seal which prevents the ingress of moisture and dirt into the housing section in which the rotary switch is located.
