Patent SE-8204823-D0 (SE)
Inventor: HANSEN ANKER JON
IPC: G01N33/38
Filed: 1982-08-24
Abstract: A method and a device for measuring the maturity of concrete, in which the heat generated by the setting of the concrete causes a special liquid to evaporate and the amount of evaporated liquid is taken as a measure of the concrete maturity. The liquid is contained in a closed capillary tube placed on a scale. For measuring purposes the capillary tube is broken at a well-defined point, and capillary and scale are then placed in a casing containing an absorbing agent for the evaporated liquid. The casing is hermetically sealed and pressed into the concrete. For reading purposes the casing is opened and the scale with the capillary is removed to determine the level of the liquid column and thus the maturity of the concrete.

Abstract: A multiple circuit brake system is proposed, in which a pneumatic and an electric brake circuit each supply the front axle brakes and the rear axle brakes in an overlapping control. For control of the brake pressure, a pressure control valve (11, 25, 38) is used, which ensures that on the one hand the control circuits are always in use and that on the other the pressures entering the respective brake cylinders balance one another out. In this way all the brake circuits are always operative and an operating check can be carried out during any braking. <IMAGE>

Abstract: A force-measuring device for contactless measurement of the feed force transmitted from a drive machine via the drive shaft (4) onto a rotating tool (9) is proposed, in which the tool (9) is connected in a force-closed fashion to the drive shaft (4) via an elastic springing element (6). In order for the offset which occurs due to the bearing play not to act as a measurement error, a measuring ring (13, 14) is rigidly connected in each case both to the drive shaft (4) and the tool (9). Depending on the particular distance between the two measuring rings (13, 14), a sensor (15, 16) generates a measurement signal corresponding to the feed force. The bearing play has no effect on the distance between the two measuring rings (13, 14).

The recess (5) is shaped so that the walls (15) defining the recess at least in one direction are located at a shorter distance from one another than the walls defining the hole (6). When the two elements (1 and 2) have been joined into engagement with each other and into the intended, relative position, the opening (6) is supplied with a locking element which is brought to a displacement into the opening and into an engagement with said walls (15) defining the recess (5) at the same time as the locking element is into engagement with the hole (6), whereby the two elements are locked against relative turning. The locking element can be a part of a tool used when the elements are joined to the intended, relative position, whereby the locking element is cut off from the tool.

Abstract: The invention concerns equipment for bricklaying of prefabricated chimneys and comprising a stationary frame construction 2,3,4,6. In order to enable bricklaying of the chimney to be carried out from one and the same position at a convenient working height, without the need to build scaffolding, work on roofs, etc., the frame construction forms a vertical guide 4 for an upward/downward movable operating frame 5 with carrier arrangement 14 for the chimney elements which are to be laid one at a time against the above-lying element or several elements A5-A8 laid together, and raised a vertical distance corresponding to a full element height at each lift. The stationary frame construction is provided with a side frame 6 at a convenient working height above the chimney's lower end. The side frame 6 comprises mainly horizontal slide rails 7 which extend into the area of the upward/downward moving element carrier 14, so that a chimney element A4 which is arranged on the side frame's support surface for the application of mortar onto its upper side, possibly lying on a thin slide plate 8, can be moved along the slide rails 7 to a position where it will lie beneath chimney element A5 or several elements A5-A8 situated above so that, by lowering the element carrier 14, it can be laid together with the said above- situated element or several elements respectively. In this position, the element carrier 14 is arranged so that it can be opened and then lowered alongside the mortar- coated element 4 which has been fed in from the side frame 6. After that, the element carrier 14 is closed beneath the said element A4 and, supporting this element and the above-situated chimney elements already laid together, the carrier 14 is raised a vertical distance corresponding to a full element height, after which the said procedure is repeated until the required chimney height has been attained. <IMAGE>

Abstract: A method and a device for centrolling, during slow acceleration of the working movement of a hydraulic cylinder and/or motor, a flow delivered under pressure from a pump system (100), especially an adjustable pump with a combined constant power and constant pressure control, so as to obtain a practically loss-free acceleration in that no excess flow is supplied to the working cylinder or working cylinder or motor. This is achieved during the acceleration process by operating in different ways, either only the pressure control level of the pump system (100) by setting means (702), or simultaneously also the setting of the beginning of the power control of the pump system (100) by setting means (701). Said setting means (701, 702) consist e.g. of a piston and cylinder assembly or a proportional magnet the force of which generally acts on a preloaded adjustment spring. The setting of the pressure control level or the beginning of the power control during the acceleration of the working movement of a hydraulic motor (251) is brought about, e.g. by having the servo (pilot) pressure (control signal) from the remote control system (300) by means of which the hydraulic motor is operated to directly act on both ore one of the setting means (701, 702).

Abstract: The two signal monitoring channels are connected to the level monitoring electrode and, when the water level is below that predetermined by the electrode, provide an alarm. Using a relay (RE1,RE2) for each signal processing channel, the boiler installation is stopped by switching off the necessary voltage supply. Only after manual activation, can the accident protection be reset and the boiler installation restarted. The relay spring groups used to close/break the voltage feed are connected in series, and via a non-galvanic connection for each relay (RE1,RE2) are connected to an optical signal unit (LED1, LED2) applicable to each relay. A first optical siqnal unit (LED1) indicates when the actual contact spring groups in both relays assume a position corresp. to normal drive. Only the second optical signal unit (LED2) is activated when the contact spring groups in both relays adopt a position corresp. to the release of the protection unit, while a persistent signal indication from the optical units indicates that one of the monitored contact spring groups is not carrying out correct movement.
