Title: Seal construction
IPC: F16J15/36
Filed: 1979-04-04
Abstract: A seal 41 for a coolant pump of an internal combustion engine includes an annular cup 51 which is secured to the pump shaft and a tubular cartridge 42 is secured to the pump housing. The cup 51 carries an annular seal ring 53 having one face engaged by an annular seal ring 61 carried by the cartridge 42 and biased axially into engagement with ring 53 by a spring 87. The ring 61 is sealed to the cartridge 42 by a flexible annular bellows 66 surrounding the spring 87. The seal parts are subjected to high rotational torques during operation and are constructed and assembled to accommodate these torques. The bellows 67 has a composition which withstands the engine coolant on one side and oxidation on the other side, and has strengthening ribs. The seal rings are of a material and have dimensions to reduce the magnitude of the rotational torques. The seal components are secured together by coolant resistant adhesives to prevent their separation by rotational torques. <IMAGE>

Title: Folding handle and fishing reel incorporating it
IPC: A01K89/00
Filed: 1979-06-27
Abstract: A handle (1) is mounted on shaft (3) to rotate about pivot (4) from a working position to a retracted one. To lock the handle releasable in the working position a collar (8) is mounted on the shaft (3) and resiliently urged by spring (10) towards the handle. A pair of tongues (12) on the collar extend generally along the axis of the shaft, one on each side of the shaft, and engage between abutment faces of slots (7) on the handle. The faces are in planes set at angles such that they are radial of the axis of the handle or undercut with respect to the radial to facilitate retention of the handle in a working position during use. To release the handle the collar (8) is slid manually against the spring. The handle can be held in its restracted position by abutment of plane faces (6) on the handle which are generally tangential of the axis (4) with a plane face on the end of the tongues (12). <IMAGE>

Title: NMR Spectrometers
IPC: G01R33/46
Filed: 1979-07-06
Abstract: In a pulsed NMR spectrometer resonance signals are detected in phase-sensitive detector 9 and second quadrature phase-sensitive detector 10 gives an output used to obtain a signal to control the resonant frequency of receiver coil 2. Preferably the output of quadrature phase- sensitive detector 10 is switched to sample and hold circuit 13 immediately after the dead time after an rf. pulse. The output of circuit 13 is switched to integrator 15 during the recovery period before the next rf. pulse to control the tuning of the receiver coil. Phase-sensitive detector 10 can also provide a signal to stabilise the magnetic field. This signal is also switched to an additional sample and hold circuit after the dead time. The output of the additional sample and hold circuit is applied to an integrator during the recovery period. Additionally the angle of a 90 DEG  transmitter pulse can be set up accurately by an initial sequence of two nominally 90 DEG pulses which produce a zero signal if they are of correct angle. Any residual signal is used to correct the pulse angle. <IMAGE>

Patent GB-2050207-A (GB)
Title: Making camshafts
IPC: B21D39/04
Filed: 1980-05-20
Abstract: The invention relates to camshafts. Known camshafts are produced predominantly from solid castings on which selective hardening treatments are applied to produce the desired qualities at the bearing and cam surfaces. As this surface quality must be high, the manufacturing processes are expensive and time consuming. According to the present invention, a camshaft comprises a carrier tube (4) and separate cam-forming elements and/or bearing surfaces in the form of tube portions (5) secured thereto. Securement of the tube portions (5) to the carrier tube (4) may be by soldering or welding; shrink-fitting; mechanical or hydromechanical expansion of the carrier tube (4); or hydromechanical pressing of the tube portions (5) onto the carrier tube. The invention enables the individual parts of the camshaft to be produced separately, and in different materials, reduces the subsequent treatment required to the camshaft; and results in a cost and weight saving. <IMAGE>

Title: Measuring Particles in Fluids
IPC: G01F1/74
Filed: 1980-08-21
Abstract: An arrangement for detecting and measuring solid or liquid particles (13) suspended in a moving fluid includes a light source (11) and a photodetector disposed so as to receive light from said source through the moving fluid.

Patent GB-2094106-A (GB)
Title: Transmission system
IPC: H04L25/49
Filed: 1981-01-13
Abstract: In a transmission system of the two-wire time separation type, data bursts are sent alternately in the GO and RETURN directions. Each burst ends with a suffix, usually 1 bit for balancing purposes, which does not convey other intelligence. Hence the transmission of the next burst overlaps the reception of this suffix: this improves the margin available between GO and RETURN Transmission.

Patent GB-2087566-A (GB)
Title: Field sprayer monitor
IPC: G01F9/00
Filed: 1981-10-23
Abstract: A sprayer monitor system for indicating to an operator various parameters such as the rate of application of fluid, the volume applied, the true ground speed and the area covered. Speed 10 and fluid flow 11 pulse signals related to vehicle speed and fluid flow rate are applied to a control circuit 6 which has constants stored during calibration. With an additional stored constant related to the spray width, the control circuit 6 determines the aforenoted parameters as a function of the speed and flow rate signals by dividing the fluid flow rate signal by the product of the speed signal and the value of the constant related to the spray width. The resulting signal, connected by appropriate calibration constants, is then displayed on display 7. <IMAGE>

Title: Laminated films
Inventor: TOUGH WILLIAM HAMISH
IPC: D04H13/00
Filed: 1982-07-09
Abstract: The present invention provides a non-woven material comprising a pair of overlaid stretch orientated films with the direction of stretch orientation of the films extending substantially transversely to each other, the films being stitch bonded together with the stitching causing fibrillation of at least one of the films. Preferably the films are arranged obliquely so that the stitching creates a structure comprising weft elements formed from the films bonded by the stitching yarn, and a series of saltire form fibril pairs also formed from the films linking successive weft elements. Such a structure provides a material of considerable strength and stability particularly by virtue of the presence of the saltire form fibrils.
