Patent GB-2106598-A (GB)
Title: Laminated blades for turbomachines
Inventor: CORRIGAN CHARLES EDWARD
IPC: F01D5/18
Filed: 1982-05-10
Abstract: A laminated blade, e.g. for the turbine of a gas turbine engine, is cooled by a cooling flow which is supplied to an interior cavity 74 of the blade, and eventually discharges through the working surfaces of the blade into the main working fluid stream. The passages 84, 86, through which the cooling flow passes in reaching the surface of the blade are formed by etching away selected parts of each lamina 62 to a reduced thickness, before assembly of the laminae into a complete blade. The convex side of the blade is internally cooled by the impingement of flows of cooling fluid from openings 84 against the inside 85 of the blade wall 70; the cooling fluid then passes through passages 86 to be discharged at the concave side of the blade, at a shallow angle to the main fluid flow, to provide film cooling. Each exhaust opening 86 has a groove-like continuation on the blade surface to the next downstream exhaust opening. The blade may be formed by laminations extending lengthwise, rather than chordwise, of the blade. <IMAGE>

Title: A hydrodynamic torque converter with a hydrodynamic lockup clutch
Inventor: GAUS HERMANN
IPC: F16H45/02
Filed: 1982-12-21
Abstract: A hydrodynamic torque converter functions by means of a converter output-rotor (6), this output-rotor being installed inside a casing-shell (3, 43) which is connected in a rotationally fast manner to a converter input-rotor (8) and which can be driven by a propulsion engine, it being possible to connect the converter output-rotor (6) to the casing-shell via a hydrodynamic lockup clutch (27), the clutch-halves, impellers (1, 5), thereof being installed with an annular clutch-space (28) which is located inside the casing-shell, beside the converter output-rotor, and having an outside diameter approximately equal to that of the converter output-rotor (6). A ring-shaped actuating piston (21) is installed, in the casing-shell, concentrically with respect to the clutch-space (28), and interacts with the lockup clutch (27) to engage and disengage the drive. This avoids the disadvantage, when lockup is effected mechanically, of having to damp vibrations which are introduced from the engine, or from the output-drive. <IMAGE>

Title: A trocar for forming an opening through the skin
Inventor: GILL DR STEVEN STREATFIELD
IPC: A61B17/34
Filed: 1984-09-27
Abstract: A trocar, which is used for forming an opening through the skin of a patient, and in some cases for distending the opening after it has been made has components which can be opened by a lever mechanism and which do not increase in cross-section towards the distal end even in the open condition. Consequently, after operation of the lever mechanism to distend an opening, it is still possible to slide the trocar out of the opening without tearing the skin. The lever mechanism is arranged so that there is a central opening through which it is possible to pass a tube when the trocar components are in the open condition. <IMAGE>

Patent GB-2171340-A (GB)
Title: Toolholder
Inventor: FRAUHAMMER KARL
IPC: B25D17/08
Filed: 1986-01-23
Abstract: A toolholder for rotary/percussive tools comprises a coupling sleeve (6) containing in longitudinal perforations (12) axis-parallel locking bodies (11) which, to effect axial locking, engage into closed grooves (10) of an inserted tool shaft (9). The coupling sleeve (6) together with the locking body (11) is surrounded by a sliding sleeve (7). Inside there are working surfaces which act on blocking surfaces facing them to lock and release the locking bodies (11). The working surfaces have approximately axis-parallel radial control surfaces (19, 21) which are stepped in the axial direction and which are at increasing radial distances. The locking bodies (11) are provided with corresponding axis-parallel blocking surfaces (16, 17) which are likewise stepped in the axial direction and which are in steps at increasing radial distances. As a result of axis-parallel displacement of the locking bodies (11) via the sliding sleeve (7) in relation to the fixed control surfaces (19, 21), the locking bodies (11) can move out radially and release the tool shank (9) and, conversely, move radially inwards for locking. The stepped control surfaces (19, 21) are contained in a control ring (18) fixed on the coupling sleeve (6) (Figure 1). <IMAGE>

Title: A high resolution magnetometer for sensing metallic samples
Inventor: PARKER DENNIS AMERENA
IPC: G01N27/72
Filed: 1986-10-09
Abstract: A particle sample (6) to be measured is placed in the alternating field of one of a pair of transducers 1 and 2. Each transducer (Figure 1) is comprised of in part a high permeability magnetic path (5), shaped to have a central limb, around which is positioned an excitation coil (4), and an outer return limb. The rest of the magnetic path consists of an air gap in which a detector coil (3) is positioned to be co-axial with the excitation coil. The outputs of the pair of transducers are compared (Figure 3). The e.m.f. induced by the sample appears as a difference signal which is further amplified by an amplifier (7) and after further amplification stages is passed through a phase sensitive detector (13) and an indication of the number of particles in the sample is displayed on a unit (14). Zeroing of the device, prior to introduction of the sample 6 can be achieved either by varying the position of two metal masses one ferrous, one non ferrous, on the axis of the unit or by adjusting a variable resistor coupling the detector coils to amplifier (7). <IMAGE>

Title: Fluid filtering system
Inventor: WHYTE JON FRANK ROSS
IPC: B01D29/11
Filed: 1987-03-23
Abstract: A fluid filtering system comprises two filter units 1, 2 arranged in parallel so that during normal operation fluid is caused to flow through both filter units simultaneously by valve 19 in its central position. Each filter unit 1, 2 includes a filter element 3, 4 and back-flushing means in the form of nozzles 7 to 10, which rotate in use while also being axially moved by pistons 11, 12. The pressure drop across unit 2 is monitored by means 58, which moves valve 60 when said pressure drop increases, thereby initiating a cleaning cycle in which valve 19 first switches flow to unit 2 alone while unit 1 is back flushed. When piston 11 reaches its lowest position, flange 51 moves valve 54, causing valve 19 to switch flow through unit 1 while unit 2 is backflushed. Finally flange engages lever 56 to restore the system to parallel flow through both units. <IMAGE>
