Abstract: A valve system having a valve with a moveable armature and a pneumatic actuation apparatus, a controller, a computer program product for simulating operating behavior of the valve system and an operating method for the valve system, wherein the valve is provided in an active operating state and a valve position to be approached is specified, a target differential pressure corresponding to the valve position to be approached that is to be set in the pneumatic actuation apparatus is determined, a differential pressure in the pneumatic actuation apparatus is changed and the differential pressure present is detected, and the differential pressure present is stabilized if a deviation between the differential pressure present and the target differential pressure falls below a settable threshold value in terms of amount.

Abstract: An electropneumatic control system for a pneumatic drive and electropneumatic position controller for the system, wherein a volume flow booster having a bypass valve is downstream of the position controller to increase the air capacity, where the pneumatic drive is run in a new operating mode multiple times at maximum air capacity in a first direction to support an operator in adjusting the bypass valve, and where upon exceeding a specified position, the air capacity is set to zero, an overshoot value of the pneumatic drive is determined and output for the operator on a display such that by varying adjustment of the bypass valve, the operator can find and set an adjustment of the valve having low overshoot such that with an adjustment found in such a manner, the transition behavior of the control system can be significantly improved without additional effort.

Abstract: Systems and methods are provided for attaching flexible conduit to an adapter. A pin is inserted opposite a retention rib molded into an aperture of the adapter. Due to the geometry of the flexible conduit and the location of the pin and the retention rib, once inserted, the pin secures the flexible conduit and prevents the flexible conduit from coming loose.

Abstract: Systems and methods are provided for attaching flexible conduit to a fitting. Prongs of a conduit retention clip contact opposite sides of the flexible conduit in an aperture of the fitting. By aligning the prongs in grooves of the flexible conduit, the flexible conduit is held in place in the aperture of the fitting without sufficient compression to surpass the structural limits of the fitting.

Abstract: Novel apparatuses and methods for depositing or placing substances on substrates or plates are described. The invention relates to automated and semiautomated apparatuses and methods for controlled volume and precise placement of substances on substrates. Combinations of applicator tips, applicator tip assemblies, applicator reservoirs, applicator holders and movable racks precisely and accurately place samples and testing chemicals on substrates. Applicator tips particularly useful for dunk transfer and deposit processes and for carrying substances are disclosed. Apparatuses for precisely moving applicator holders, applicator reservoirs and tips are disclosed. The methods and apparatuses also have features for pre-loading substances on applicators and applicator reservoirs and precisely delivering the preloaded substances to substrates.

Abstract: A golf swing training aid permits the user to verify that the face of the golf club has not been inadvertently rotated during the back swing and/or the downswing. The golf swing training aid permits the user to confirm the rotation or lack of rotation of the golf club face without requiring lifting of the head and/or shoulders of the user.

Abstract: A data processing system, wherein a data flow processor (DFP) integrated circuit chip is provided which comprises a plurality of orthogonally arranged homogeneously structured cells, each cell having a plurality of logically same and structurally identically arranged modules. The cells are combined and facultatively grouped using lines and columns and connected to the input/output ports of the DFP. A compiler programs and configures the cells, each by itself and facultatively grouped, such that random logic functions and/or linkages among the cells can be realized. The manipulation of the DFP configuration is performed during DFP operation such that modification of function parts (MACROs) of the DFP can take place without requiring other function parts to be deactivated or being impaired.

Abstract: An inflatable bed-pan pad-support of the invention has a shape geometry and configuration in its deflated state that is different from that in its inflated state, so that, when the pad is inflated, it assumes a natural, rectilinear-shaped outline, with the bed-pan receiving, U-shaped opening thereof having a substantially uniform width along its length when the pad is in inflated. Strengthening ribs are provided in the interior of the pad, which additional strengthening ribs extend between the closed, head end of the bed-pan receiving, U-shaped opening and the opposite, head-end end-wall of the pad, which strengthening ribs provide the necessary support to the bed-pan receiving, U-shaped opening so that it assumes, in its inflated state, a uniform width substantially along its length. Another pair of outer strengthening ribs are also provided, one on either lateral side of the U-shaped opening strengthening ribs.

Abstract: A system measures and records deflection of an elongated shaft such as the shaft of a golf club and provides a trace or diagram of the swing of the club. The system includes an elongated rod, mounted to the golf club shaft, and a separate recording system. Preferably the recording system is a writing platform mounted to the golf club shaft. The recording member is biased into contact with the writing platform. During swing of the golf club, deflection of the golf club shaft causes relative movement between the writing implement and the writing platform and a trace or diagram of the golf club swing is created.

Abstract: A collapsible bed-pan support or pad for bed-ridden persons. The pad has a U-shaped opening provided with a pair of camming, catch members for removably retaining a bed pan in place. The U-shaped opening is reinforced along its annular wall to prevent bulging, in order to better retain the bed pan in the U-shaped opening of the pad. A bottom apron is provided to protect bed sheets while the bed pan is being used. A specially-designed bed pan cooperates with the camming members of the pad to retain the bed pan in place.

Abstract: A collapsible bed-pan support for bed-ridden persons, which has an upper supporting surface that inclines from its head-end toward its feet-end in order to gradually elevate the back of the patient. A series of webs of different height provide for the upper sloping supporting surface. The support is made of thin, flexible material that, when collapsed, is only about 1.5 mm. thick, so that the bed-pan support may remain underneath the patient until required for the next use of a bed pan.
