Title: Measurement device with strip scale for easy reading - uses reference scale point adjusted electrically or pneumatically
Inventor: METZ WALTER ING GRAD
IPC: C01D7/02
Filed: 1980-09-18
Abstract: A measurement instrument with an analogue scale and for a digital display for measurement values, esp. one whereby the display involves a band moving along a plane scale, is designed for ease of reading of the displayed values. The desired value of a monitored process parameter can be set at a defined scale point, pref. the centre point of the scale or a predefined digital value, pref the value '+ or -O'. The indicated measurement value is the actual value normalised to the desired value. The adjustment to the defined scale point or digital value is achieved by using a defined electrical parameter, pref. a voltage obtained from a potentivemeter or a predefined digital value when the measurement value is an electrical signal, when the measurement value is a pneumatic signal a regulator is used.

Title: Backflow preventer
Inventor: STRANGFELD REINER DIPL ING
IPC: F16K15/06
Filed: 1981-04-02
Abstract: In this backflow preventer, which is to be regarded as a constriction fitting, the movably guided valve tappet (1) is supported in the closed state, by means of a collar (7), on a shoulder (8) beneath the valve seat (2). On the valve tappet (1) there is fastened, in the region of the valve seat (2), a flexible sealing disc (4), leaving a free outer region. Said free outer region is pressed onto the valve seat (2) by a restoring spring (5). The restoring spring (5) only acts on the valve tappet (1), via the sealing disc (4), in the open state of the valve. High counter-pressures are absorbed in that the collar of the valve tappet is supported on the shoulder beneath the seat. On the other hand, the flexible sealing disc being pressed onto the seat also achieves leak-tightness in the case of low counter-pressures. <IMAGE>

Title: Method for shaping a hair strand by heating, and hair-shaping equipment therefor
Inventor: MATTINGER DETLEF
IPC: A45D7/02
Filed: 1982-04-23
Abstract: Air supplied by a fan (3) is partially fed via a heater winding (6) to a hot air chamber (10) of a cylindrical curling body (8) and emerges through radial hot air exit openings (13). Through a bypass duct (7) led past the heater winding (6) cooling air passes into a cooling air chamber (11) in the curling body (8). A perforated guide surface (14) surrounds the outer wall (12) of the hot air chamber (10) at a distance from the latter. The hair strand to be styled is laid around the curling body (8). The curling body (8) is then moved away from the scalp, the hair strand initially sliding over the outer wall (12) of the hot air chamber (10) and then over the outer wall (23) of the cooling air chamber (11). As a result the hair strand is heated and cooled in immediate succession and thereby retains its wavy or curly shape which it assumed at the outer wall (12) of the hot air chamber (10). <IMAGE>

Title: Method and device for determining the flow rate in a liquid
Inventor: ROSEN HERMANN
IPC: G01F1/00
Filed: 1982-06-23
Abstract: In a method and device for determining the flow rate of a liquid in a channel region through which flow occurs with a free liquid level and which is measured both with regard to its liquid level and with regard to its flow velocity by measurements of propagation time and/or frequency, the robustness and the measuring accuracy required in practice and the simple manipulation to be stipulated are achieved by means of a new development making use of the realisation that both the level and the flow velocity can be measured by beams directed from above onto the liquid level. Use is made, for this purpose, of beams of a type reflected at the liquid level towards the air, such as, for example, ultrasonic, radar or laser beams and at least one of these is directed obliquely in or against the flow direction. It is expedient for a second beam to be directed perpendicularly onto the liquid surface. It is possible by means of measurements of propagation time and frequency to calculate both the liquid level and the flow velocity and thus the flow rate, and to store them electronically using known means.

Patent DE-3230306-A1 (DE)
Title: Heat exchanger
Inventor: HAGE MANFRED DR ING DR
IPC: F25B39/04
Filed: 1982-08-14
Abstract: The invention relates to a heat exchanger (1), especially a condenser, for the refrigerant in heat pumps, which has mutually parallel-connected pipe coils (7-14), for water throughflow, between a middle feed duct and outlet duct in a closed cylindrical container (2) with a cover (4) and floor (3), each pipe coil (7-14) having its own inlet pipe (7'-14') and its own outlet pipe (7''-14'') respectively opening into a common feed channel (5) and into a common drain channel (6), and which heat exchanger (1) has a pressure pipe (16) and a suction pipe (17) for the refrigerant, according to Patent... (Patent Application P 3208838.8-13). As a development of the subject of the main patent (Patent Application P 3208838.8-13), it is proposed to arrange the feed channel (5) and the drain channel (6) outside the container (2) at a spacing from the floor (3) or cover (4). Solder joints between the refrigerant and water are thus avoided inside the container, and contamination of the water in the event of a possible leakage is thus prevented. At the same time, sufficient supercooling of the refrigerant is ensured. <IMAGE>
Patent DE-3233302-A1 (DE)
Title: Non-return valve which can be shut off
Inventor: JENSEN NIELS DUE
IPC: F16K15/18
Filed: 1982-09-08
Abstract: Such a non-return valve is equipped with a hand-operated device in order to shut the valve passage off for a long period. The device operates by the valve body being held in a sealed manner against the part which has the valve seat. According to the invention, the valve seat part is displaced axially so far while maintaining its sealing contact, or assuming a sealing contact, on the valve body until the valve body rests against its stop which limits a maximum opening movement. In consequence, the non-return valve produces no disturbing flow noises, and no additional flow losses in normal operation.
Patent DE-3236983-A1 (DE)
Title: Device for the attachment of pipes, in particular in vehicles
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: F16L3/237
Filed: 1982-10-06
Abstract: The device consists of a pipe holder which is pushed onto a threaded bolt and is connected thereto in a positively locking manner. The supply lines are preinstalled in this pipe holder like a clip. The final attachment takes place by pushing a closing securing device onto the threaded bolt where a positively locking connection is then likewise provided. In addition, the pipe holder and closing securing device are additionally connected to one another via clips. This results in a type of attachment which completely surrounds the pipe. The external contours of the attachment bodies are configured such that they run in a tapering manner towards the pipes. This produces a deflecting function for obstructions (such as junctions) which strike them and additionally a contour which is streamlined. <IMAGE>

Patent DE-3242240-A1 (DE)
Title: Rain basin
IPC: E03F5/10
Filed: 1982-11-15
Abstract: Rain basins serve the purpose of storing quantities of rain water occurring in surges until they can be received by the normal treatment system. A disadvantage which has been found is that during the course of the storage time contaminating material is deposited on the bottom of the basin and has to be removed again. One possible way of removing the contaminating material is for the water to be introduced tangentially, thereby producing a flow which is directed towards the centre of the basin and flushes away the contaminated particles. In order to maintain this cleaning bottom flow for as long as possible and in order to avoid flow resistances, the invention proposes for a flow baffle, designed as a rotational body, to be arranged centrally and for an annular discharge duct with outflow pipe to be provided at the foot of the flow baffle. <IMAGE>
