Title: Chromatograph for high-pressure chromatography
IPC: B01D15/08
Filed: 1981-10-06
Granted: 1984-12-19
Abstract: In this chromatograph for pressure chromatography, a plunger having a plunger stem is arranged so that it can move within the separation column (3). On the front face of the plunger there is a collecting space (7) for liquid, which is covered by a frit (6) and which has a connecting line (8) to the face of the plunger opposed to the front face. In order to prevent abrasive and chemical attack by the column packing on the plunger, its seal and the cylinder wall of the separation column, the plunger should comprise a lower part (2) having a device (4) to accommodate the plunger stem (5), and an upper part (1), the two parts being arranged so that they can move in relation to one another. The upper part (1) has a centering peg (9) which projects into the lower part (2). A spring (12) on which the upper part (1) is supported, is located concentrically in relation to the peg (9). The upper part (1) has recesses on its circumference to accommodate at least two seals (19 and 21) and a ring channel (16) which is formed by a retaining ring (13) for one seal (19) and is connected to the collecting space (7). The other seal (21) is held in its recess by a ring (23) which is located concentrically around the spring and is supported by the lower part.

Title: Dial and pointer electrical instrument
IPC: G01D11/24
Filed: 1981-08-14
Granted: 1985-04-17
Abstract: In order to allow a wide range of instruments to be assembled from standard modules, there is provided a range of different diameter housings with their glasses spun in and sealed by an O-ring. A housing can be trimmed to length as required. Different types of panel mountings can be fixed over the front rim of the housing. One of a range of standard movements is mounted between plates and matched to the housing diameter and retained therein by releasable catches. The catches may be turnbuttons cooperating with pegs projecting inside the housing. Alternatively, leaf spring catches slidable radially outwardly on the plate can engage in an annular groove inside the housing and be locked in position by clamp screws. The rear end of the housing is plugged by an O-ring sealed base which carries either a terminal part/connector structure only or also a range scaling circuit enabling the same movement to handle different input signal ranges. The pointer on an offset arm sweeps over a scale which can be hub lit. For small instruments where cylindrical space available radially inside the arm is small, bulbs are mounted in a radially offset position (where the needle does not sweep) of a transparent body to direct light radially inwardly to a 45 DEG surface where internal reflection directs the light axially along a cylindrical lens part from which the light diffuses radially over the scale. Alternatively, the 45 DEG  surface can be omitted by locating the bulbs close to the axis in a recess through which the bulbs can be withdrawn in the radial direction.

Patent EP-0064179-B1 (EP)
IPC: B65G65/00
Filed: 1982-04-13
Granted: 1985-03-13
Abstract: A transfer apparatus wherein the conveyed loads, which need not absolutely possess a square or rectangular cross-sectional area or configuration, are received by or delivered from a transport vehicle, without the load itself having to experience a tilting movement, when it departs, for instance, from a stationary chain conveyor and is taken-over by the chain conveyor of a displacement carriage. The gap between the stationary chain conveyor and the chain conveyor mounted upon the transport vehicle is bridged by the laterally movable displacement carriage. The related chain drive serves for moving the conveyor chains of the chain conveyor and the displacement carriage. An alternately effective brake-locking device controls both movements. With blocked conveyor chains the displacement carriage, depending upon the direction of rotation of the drive motor of the chain drive, moves laterally in one or the other direction until reaching a related lateral stop or impact member. With released conveyor chains and blocked displacement carriage the conveyor chains of the chain conveyor are displaced until the conveyed load can be transferred or received, as the case may be.

Patent EP-0137211-B1 (EP)
IPC: F01K25/06
Filed: 1984-08-10
Granted: 1989-10-25
Abstract: An absorption type heat transfer and thermally powered temperature pressure potential amplifier system for storing energy by distilling and separating solute from a solution of the solute and a solvent at a low temperature, then amplifying and recovering the temperature and/or vapor pressure potential difference between the solute and the solution at a higher temperature in the form of heat transfer or its mechanical power equivalent. One working fluid is a solute having a low boiling point, the other a solution of the solute in a solvent having a high boiling point such that mutual solubility is poor at low temperatures as indicated by a small vapor pressure difference between solute and solution, and in which the vapor pressure difference between solute and solution greatly increases at higher temperatures. This permits the vapor pressure potential difference to be released in the form of mechanical work when vapor from separated solute is reabsorbed into solution in an absorber at the higher temperature. Similarly, an amplified temperature difference exists between liquid solute and absorbent solution in a high temperature absorber when solute vapor passes freely into solution within the absorber. The working fluids are circulated in a closed cycle with an intermediate counter-flow heat exchange means for exchanging heat between separated solute and solution moving from the colder distilling means, and recombined warm solution returning to the colder distilling and separating means from the higher temperature absorber. This system utilizes low grade heat from natural sources.

Granted: 1989-03-29
Abstract: A shifting coupling which is preferably provided for the travel mechanisms of overhead conveyors, and which operates in a positively engaging manner counter to a spring which acts in the disengagement direction. The coupling projections or engaging members, which are provided on a coupling flange, are controlled with the aid of two sleeves which are movable relative to one another. Those ends of the sleeves which butt against one another are provided with oppositely extending conical surfaces. Control balls can be pressed into the wedge-shaped recess which results between the two conical surfaces. The control balls press the two sleeves apart in order to engage the coupling. A control sleeve, which is provided with inner conical and annular surfaces, serves for the radial movement of the control balls. During the engagement process, the control sleeve is resiliently prestressed in such a direction that the conical surface thereof contacts the control balls in the direction of coupling engagement. The actual engagement process is not triggered until the positively engaging, intermeshing coupling members are aligned with one another, and the two sleeves are driven apart by the control balls, to the extent that a spring tension acts thereupon.
