Abstract: 1. Hydraulic control device for controlling a hydraulically actuated working cylinder, in the branch line of which, leading from the working cylinder to the tank, is inserted a built-in two-way valve which serves for regulating the pressure in the working cylinder and which can be pilot-controlled by a proportional pressure control valve via a first control line, and with means for path control between the working cylinder and the tank as well as with a throttle point, via which a control pressure medium can enter the first control line and reach the proportional pressure-control valve, characterized in that the built-in valve (23) is designed as a pressure-balance cartridge with end pressure faces (25, 28) of at least approximately equal size, the closing body (26) of which can be loaded in the direction of the open position by the pressure to be regulated in the working connection (24) and by a spring (27) and in the direction of the shut-off position by the pressure in the first control line (31) and consequently in the control space (29), in that the closing body (26) is assigned a release piston (36) which is loaded by a second spring (39) and which limits two pressure spaces (38, 43) connected respectively to a second control line (44) and a third control line (38) and alternately subjectable to the control pressure medium in such a way that, when the release piston (36) is coupled to the closing body (26), the stronger second spring (39) keeps the closing body (26) in the shut-off position for the path function, whilst, when the release piston (36) is uncoupled from the closing body (26), the delivery function can be controlled from the proportional delivery valve (33) via the first control line (31).

Abstract: A positive displacement pump (310) utilizes at leastthree driven displacer valves (360,362,364) and a plurality of driving membranes (336,340,344) and at least one pumping membrane (316) to withdraw minute quantities of corrosive fluid from a drum (100) and discharge same to a delivery point (128). The pump (310) is submerged within the fluid to be pumped and is driven by a remotely positioned pneumatic pulse generator (116) comprising pneumatic logic circuitry. The driven displacer valves (360,362,364) operate in a particular sequence to draw fluid into the pump body (312,314), advance same in succession through pumping chambers (318,320,322) within the pump body (312,314), and then discharge same at a constant rate of discrete pulses through an outlet port (332). The pulse generator (116) and logic circuitry provide the control pulses for operating the displacer valves (360,362,364) at the proper times in the operational cycle. The delivery characteristics of the pump far exceed the performance capabilities of conventional pumps utilized for similar purposes.

Abstract: A rotary ultrasonic scan head includes a housing 10 consisting of generally symmetrical housing portions 10A and 10B having respective mating surfaces 14 and 16 that abut when the housing portions are assembled. A cavity is defined within the housing by recesses 18, 27, 34 and 38 in housing portion 10A and by complementary recesses 20, 28, 36 and 40 in housing portion 10B, by boot 50 disposed on the housing portions in assembly, and by pressure-compensating diaphragm member 42 disposed within the housing portions in assembly. A rotor 12 including a plurality of ultrasonic transducers 22, an impeller 24, and an optically encoded member 26 is supported for rotation within this cavity. An acoustic coupling and driving fluid is supplied to and withdrawn from the cavity through fluid inlet bore 68 and fluid outlet bore 70 in housing portion 10A, with the fluid entering the cavity being directed at impeller 24. A rotary transformer couples electrical signals between housing portion 10A and the rotor, and a plurality of reed switches within the rotor and permanent magnets 94 and 96 disposed in housing portion 10A commutate these electrical signals so that each transducer is enabled only when that transducer is traversing a desired sector. Fiber-optic bundles 108 and 110 disposed in housing portion 10B optically couple member 26 to external light sources and detectors so that the relative angular position, speed of rotation, and direction of rotation of the rotor can be determined.

Abstract: A constant tension hoisting system is provided for raising and lowering an object between a platform and a surface undergoing vertical motion relative to the platform, such as raising and lowering a lifeboat from a seagoing vessel to the sea in rough weather. The system operates in a normal hoisting mode to raise or lower the object, and in a constant tension mode when the object is supported on the surface. The system is changed from the normal hoisting mode to the constant tension mode at the moment when the object being lowered is first supported by the surface, and a slack condition exists in the cable. The changeover from the normal hoisting mode to the constant tension mode, is performed by a solenoid-operated mode selector responsive to a proximity switch operated by a lever arm engaging the cable. The hoisting system is operated by a single, manually-actuated control lever, which mechanically activates the proximity-type control switches. An auxiliary motor connected to a ring gear of a planetary-type final drive operates the hoisting system in the constant tension mode, while a main motor operates the system in the normal hoisting mode.

Abstract: The cap for the writing instrument comprises a jacket mounted slidably on a sealing insert or sleeve which provides a sealed moisture chamber for the writing tip when the cap is on the writing instrument. Near the writing tip there is a circular bulge on the shaft of the writing instrument which enters into a sealing engagement with an interior passage of the sealing insert. On putting the cap on the writing instrument the sealing insert is pushed over the circular bulge until it contacts a contacting stop on the jacket. Then the circular bulge presses tightly into the sealing insert and it locks the jacket to the writing instrument so that the entire arrangement is kept in that position until the cap is removed. A signal slider is attached with the sealing insert which is extendable out from the end of the jacket in order to signal in its extended position the proper seating of the cap on the writing instrument. Erroneous indications of a sealed state are prevented with our invention.

Abstract: A system for remote management includes central management, planning and rationalization of the upkeep of elevator installations. The system comprises a modularly constructed remote management system, which makes possible the management centrally, the inspection regionally and the monitoring of decentralized processes locally of elevator installations. The management exchange is connected by modem and telephone network with the regional exchanges and has access to all relevant data. The regional exchange permits an inspection of all processes of several buildings. Direct speech connections with all the peripheral devices are by means or remote alarms from the regional exchange. For each building, a communications module manages the data traffic between the regional exchange and the processes to be inspected in the building. The process data is detected by a peripheral module, which is capable of diagnosis, and is processed further into relevant operational, fault and alarm reports with the aid of heuristic operating means. The peripheral module reports diagnostic data by way of the common building bus to the communications module, which transmits the data to the regional exchange by means of automatic telephone dialing.
