Patent GB-2076966-A (GB)
Title: Apparatus and method for measuring layer thicknesses of a multilayered metal member
IPC: G01S15/10
Filed: 1980-05-23
Abstract: A method and apparatus for measuring the thicknesses of a cladding layer 10 and a base metal layer 8 by applying pulses of ultrasonic waves (T) on the side of a sample opposite the cladding layer using a contact probe 1. The reflected waves are sensed by a crack detector and displayed on an oscilloscope. By eliminating noise and interference, the position of the interface 9 between the cladding layer and base metal layer are measured from a pulse (4) produced due to the discontinuity of acoustic impedance at the interface. <IMAGE>

Title: Circuit for Mains Monitoring
IPC: H02H7/08
Filed: 1980-06-13
Abstract: A circuit for monitoring a single phase or three-phase mains voltage supply comprises a full-wave bridge rectifier (4 to 9), a first comparator (13) which detects when a first threshold is exceeded by the rectified mains voltage and a second comparator (14) which detects when the rectified voltage falls below a second lower threshold. The outputs of the comparators are connected in common by way of a bias resistor (15) to a first voltage source (U1) and by way of a diode (16) and a low pass filter (17, 18, 19) to a second voltage source (U2). Voltage changes at the common output of the comparators, indicating a fault, are applied to a logic circuit (24) which may automatically disconnect the mains supply. <IMAGE>

Patent GB-2053771-A (GB)
Title: Handle for percussive tools with vibration damping means
IPC: B25D1/00
Filed: 1980-06-30
Abstract: The shank of a hammer is made of a multiplicity of vertebra members 20 that are assembled into a column. Aligned passages 30, 34 in the vertebra members provide three elongated passages in one embodiment that extend from the handle 22 to the head 12. Pultruded shafts 38 extend through two of these passages and are fixedly connected at each end to the head and the handle. The third passage 30, which is spaced toward the impact surface of the head from the other two passages, has a shaft 36 of spring-tempered tool steel extending through it that is fixedly connected to the head but slidably received in the handle. This arrangement provides a flexible shank that damps the shock produced on impact. However, the flexibility is only afforded in one direction so as not to interfere with the use of the claw portion of the head. Alternate embodiments have different numbers of shafts, and one is flexible in both directions. <IMAGE>

Title: A can opening tool
IPC: B67B7/46
Filed: 1980-08-11
Abstract: A tool 1, for opening cans or like articles, has an arm 2 fitted with a handle 3 at one end, a hook portion 4 at the other end and a cutter plate (5) slidably mounted between the hook portion 4 and the handle 3. The hook portion 4 extends under the arm 2 and has a shape to encompass, with the arm 2 the exterior of the double seam of a can. A locking bar 9 is used to retain the hook portion 4 in pivotal engagement with the double seam. In use, the hook portion of the tool is engaged with the exterior of the double seam so that the arm 2 lies across the can end. The cutter plate 5 is brought to lie over the double seam at a point diametrically opposite the hook portion so that downward pressure on the handle forces a blade 12 of the cutter plate to cut the can end. The cutter plate may be provided with four cutting points so that, by removing, rotating and then replacing the cutter, a different cutting point may be brought into operation. In a modification, the cutter has twin cutting points disposed side-by-side on either side of the arm to prevent twisting of the tool. A can-gripping vice 15, having reciprocable jaws 17, 18 mounting adjustable pegs 26 in holes 25, is provided. <IMAGE>

Patent GB-2078983-A (GB)
Title: Force transducers
IPC: G01G5/00
Filed: 1981-06-02
Abstract: A force transducer has a housing 1 with a cell 2 containing pressure- transmitting fluid and a bore 3 into which fits a piston 4. A resilient diaphragm 11 extends from the housing across the face 9 of the piston and a pad 13 of resilient material is interposed between the piston and the diaphragm. When a working load is applied to the transducer, the resilient pad 13 is compressed between the piston and the diaphragm sufficiently to urge a peripheral region of the pad against the bore 3. This action reduces the tendency of the diaphragm to be extruded between the piston and the bore. <IMAGE>

Title: Improvements in navigation lanterns
IPC: F21S8/00
Filed: 1982-05-25
Abstract: A navigation lantern for use as a beacon or buoy achieves a high intensity light output without the need for a cylindrical glass lens of large diameter by providing, in the vicinity of the focal point of the lens, a light source comprising at least two halogen type lamps. The use of more than one lamp assists in avoiding undue vertical divergence of the high intensity beam issuing from the lens, and reduces the concentration of heat generated in the lantern. Damage to lamp control electronics by heat from the lamps is further safeguarded against by the provision of a heat shield between the lamps and a terminal support block. Preferably the shield is spaced from the support block.
