Patent DE-4038813-A1 (DE)
Title: Boiler unit for gas and steam turbine plant - incorporates flue gas channel over which is fitted boiler cover and hot surface arrangement
Inventor: BRUECKNER HERMANN DIPL ING
IPC: F22B37/20
Filed: 1990-12-05
Abstract: In the area of the central axis (M) of the boiler cover (3) is an intermediate wall (27) extending from the rear wall to the front wall. Profile frames (28) are fixed to the intermediate wall in which bearer and guide grids (22) are fitted. The width (B) of a profile frame (28) with a bearer and guide grid (22) is restricted to a transport dim. so that transportable assembly units or modules with e.g. two bundles of pipes and seven support and guide grids can be formed. The intermediate wall is of the double type, and is protected against distortion by inner braces (38). During operation, it is in the exhaust gas flow, and therefore follows operating temp.. The wt. force of the hot surface arrangement conducted from the intermediate wall to the front wall is taken up via the profile frame with the support and guide grids in the two side walls (29,30) of the boiler cover (3). USE - As a boiler arrangement for a gas and steam turbine plant.

Title: Multi-blade marine propeller - has even-pitch blades in axial alignment on hub for continuous grip on water-flow
Inventor: BEHRENDT LOTHAR
IPC: B63H5/10
Filed: 1990-12-18
Abstract: The separate blades are separately fitted to the hub in successive planes.

Title: Stackable barrel with handling ring - has elastically deformable ring members to improve long term stacking
Inventor: PRZYTULLA DIETMAR
IPC: B65D45/32
Filed: 1990-12-24
Abstract: The stacking barrel has around the outer wall near the top and bottom bases handling rings (38,40). The height of the overhang (52,54) of at least one base beyond the ring (38,40) is one to five times the wall thickness of the barrel wall (30) or base (32,34). When stacked and thus under strain at least one of the conically outwardly protruding ring pieces (42,44) of the upper base (32) and/or lower base (34) is elastically deformable so that inside the barrel a supporting hydrostatic pressure builds up initially before the stacking strain is directed through the outer handling ring (38,40) and barrel edge to the outer barrel wall (30). USE/ADVANTAGE - Although there is a saving in the materials and empty weight of the barrel safe long term stacking of the barrels is possible.

Title: Electronic circuit for measuring periodic signal phase and frequency differences - has cyclic serial state machine, shift register, state identification logic and comparison logic
Inventor: WENNEKERS PETER DIPL PHYS
IPC: G01R25/00
Filed: 1991-07-19
Abstract: The electronic circuit measures phase and frequency differences of two periodic signals (FREQ1, FREQ2) using a comparator (1) with inputs for the periodic signals and a phase difference signal output. A cyclically and serially operating state machine (2) with at least two states has a clock input for the first signal (FREQ1) and an output at which the internal state appears as a periodic pulse sequence. A shift register (3) which forms an image of the state time shifted according to the phase difference has a clock input for the second signal. The internal state and the shifted state are compared by state identification logic (4, 5) and comparison logic (6) forming the comparator output (9).

Title: Axially engageable and disengageable claw clutch - is for general purpose vehicles and has linear contact between mutually engaging claw flanks during disengagement under load
Inventor: BOLL WOLF DR
IPC: F16D25/08
Filed: 1991-11-27
Abstract: The claws of the clutch extend towards the clutch axis from the claw gap base to the claw head and have rounded top edges. The geometrical position for the points of a claw flank (17, 18) lying in a plane running across the clutch axis (21-21) and dissecting the claws (9) is a straight line (24) intersecting the clutch axis (21-21). The claws are in constant keyed engagement thorugh a spring which tries to close the clutch. This spring can be very weak because its force only serves to engage the claws. In the unlocked normal operation the claws are held open against the weak spring force by an axial bearing. During the disengagement process which is carried out under full load the load moment is transferred by Hertz pressures (linear contact). USE/ADVANTAGE - Unrestricted ABS functioning is possible on general purpose vehicle, using claw clutch mechanism.

Patent DE-4213498-A1 (DE)
Inventor: BLACKERT WOLF DIETER DIPL ING
IPC: E03F7/02
Filed: 1992-04-24
Abstract: Flat gate valves without a casing, which are used, for example, in water and sewage disposal, consist of a three-sided, cast-iron guide with a U-shaped profile for the valve plate. These frames must be fastened with several plugs to uneven vertical structure surfaces without the guide frame being distorted as a result. The novel method of fastening such guide frames with plugs is characterised in that first of all plugs and concrete anchors (19) are set at just three points which do not lie on the same side of the frame and the anchors are tightened, and in that continuously adjustable distance elements (18) are then placed free of play underneath the frame at the remaining fastening points, and then the plugs and concrete anchors (19) are set there and finally all concrete anchors (19) are tightened. The frame, at least at the inner edge, has highly elastic sealing strips (15) behind which the back lining can be placed. Formwork is therefore not required for this. <IMAGE>
