Title: Automatic control of ignition advance for carburettor engines
Inventor: COTIGNOLI GIUSEPPE
IPC: F02P7/03
Filed: 1985-07-25
Abstract: A sensor (1) detects the passage of a piston or group of pistons through TDC or through a point at a pre- established angle in advance of or behind TDC. To the sensor (1) there is connected a pulse shaping circuit (5) which supplies ON-OFF type output signals (B) with two successive level switchings separated by a time interval said to be proportional to the speed of rotation of the engine each time a piston or group of pistons passes through TDC or other predetermined point. An electronic processing and control unit (10) effects ignition, via an ignition coil (T), and automatic control of the advance of the ignition, in response to the output signals (B) and to signals from sensors (6....N) detecting operating conditions of the engine. Each time rotation of the engine is started, the first signal (B) supplied by the pulse shaping circuit (5) is detected by a monitor (15), which initiates the storage of energy in the ignition coil (T) in response to the first switching level of the signal (B) followed by activation of an ignition spark in response to the second switching level of the signal (B). In this way the angle of rotation of the engine before the first effective ignition spark in the starting phase is minimised. <IMAGE>

Title: Stowing handbrake lever
Inventor: SPOONER BRIAN JOHN
IPC: B60T7/10
Filed: 1985-10-21
Abstract: A vehicle handbrake lever mechanism has a hand lever which pivots about a ratchet toothed quadrant (11) and carries with it a pawl (13) which, as the lever is moved in one direction to apply the brake, rides over the ratchet teeth; engages finally in one of those teeth to hold the brake on. The pawl (13) is pivotally mounted with respect to the lever and is coupled to a pawl disengaging button (16) such that depression of said button causes rotation of said pawl. The pawl has to be positively disengaged by depression of the button and held out of engagement (conventionally by depressing a button carried towards or more usually at the projecting end of the lever) for the lever to be moved in the opposite direction to release the brake. The hand lever (12) is made in two portions (12a, 12b) which are pivoted to one another about an axis running across the general axis along which the composite lever extends. One of those portions (12a) carries the pawl (13) and incorporates the quadrant pivot (15) while the other portion (12b) carries the pawl disengaging button (16). The pawl disengaging button (16) is permanently coupled to said pawl (13). The two portions (12a, 12b) cooperate to apply the brake; but, with the brake applied and held on, the button carrying portion (12b) can pivot away from the pawl carrying portion (12a) of the lever without disengaging the pawl (13). <IMAGE>

Title: Method and apparatus for inertial spinwelding of thermoplastic container ends
Inventor: FORTUNA VINCENT
IPC: B65D8/22
Filed: 1985-10-31
Abstract: A thermoplastic end is inertially spinwelded onto the paperboard sidewall of a container body, the end having an annular groove for snugly receiving the sidewall and a wall configuration which minimizes the forces exerted on the bond by liquid contents which would tend to dislodge the end portion. The end portion has strengthening ribs positioned generally within the region of U-shape and additional radial ribs imparting strength and rigidity to the container end. The paperboard sidewall may be internally lined with a layer of thermoplastic material or may be unlined. During spinwelding, a sidewall supporting mandrel 28 having an expandable engaging portion is inserted into the sidewall and subsequently expanded to define a cylindrical surface of a diameter equal to that of the specified internal diameter of the sidewall. A seating member at the end of the sidewall supporting mandrel establishes the depth to which the container end is inserted into the sidewall and is provided with a low-friction member which contacts and aligns the rotating container end with the container sidewall; Figs 4-9 and 13 (not shown). <IMAGE>

Patent GB-2171152-A (GB)
Title: Hydraulically powered system
Inventor: CRAMPTON DOUGLAS WALTER
IPC: F15B11/02
Filed: 1986-02-20
Abstract: A hydraulically powered system includes a pump (10) driven by an engine (13) and a sensor (24) that senses the pressure in the system and serves to trigger a reduction in the speed of the engine (13) once a predetermined hydraulic pressure is exceeded corresponding to a pressure just below that at which a hydraulic relief valve (11) is set to open. By this means, operation of the relief valve (11) and consequent venting of pressurised hydraulic fluid is reduced or avoided, thereby reducing or avoiding energy losses. Thus the system hydraulic pressure is limited through control of engine speed rather than operation of a relief valve. A controller (20) receives signals from the sensor (24) and a manual control (21, 22, 23) and provides an output signal to a further controller (18), the latter receiving a speed dependent signal from a sensor (17) and providing an engine speed control signal to an actuator (19). <IMAGE>

Title: Water blocking in cables
Inventor: BURY JOHN ROBERT IVOR
IPC: H01B7/285
Filed: 1986-08-08
Abstract: A water-blocking filling for a cable consists of a thixotropic hydrophobic material such as a petrolatum into which is mixed a small percentage by weight, 0.1% in one case, of microspheres. Each of these microspheres is of a polymeric material such as polyvynilidene dichloride filled with a blowing agent such as azodicarbamide. The filling is applied to the cable when unsheathed. The filled but unsheathed cable is now applied to an extruder to give it its outer sheath, e.g. of aluminium or an aluminium alloy. The heat generated during this extrusion causes the microspheres to expand so that interstices in the cable are filled. <IMAGE>
