Title: Standby power supply
Inventor: LAM KA DUK
IPC: H02J9/06
Filed: 1986-05-07
Abstract: In a power supply for an air pump 5, mains electricity 1 is normally supplied to the pump 5 through a relay-operated changeover switch 3, and also charges up an emergency battery 11, through transformer 7 and rectifier 9. If the mains supply 1 fails, switch 3 changes state and a DC/AC inverter 15 powered by the battery 11 then drives the pump. The output of the rectifier 9 also provides a control signal to operate both the relay switch 3 and a second relay-switch 13 between the battery 11 and inverter 15. <IMAGE>

Patent GB-2191375-A (GB)
Title: Subsoiler
Inventor: COPPERWHEAT CYRIL
IPC: A01B15/02
Filed: 1986-09-11
Abstract: A tine (10) for a subsoil cultivator comprises a depending leg (20) fitted with a shin (22) and point (28). At the heel of the leg there is a pair of wings (34) which are pivotable about respective bolts (36) between a raised substantially horizontal position which they adopt when the leg is travelling through the soil and a substantially vertical position which they adopt when the tine is being lifted out of the soil. The displacement movement is caused solely by the shape and orientation of the wings and soil pressure against them. Subsoil is therefore not brought to the surface when the tine is raised. <IMAGE>
Patent GB-2182151-A (GB)
Title: Coaxial linear magnetic scale apparatus
Inventor: INDO KENJI
IPC: G01B7/00
Filed: 1986-10-15
Abstract: A coaxial linear magnetic scale apparatus used in a machine tool or the like, includes a linear magnetic scale 5 recorded with an AC magnetic pattern at a predetermined pitch on a rod-like magnetic medium, and a multigap head having a scale hole through which the magnetic scale is coaxially inserted. The apparatus also includes a hollow guide shaft 1 having one end fixed to the multigap head 4 and slidably mounted on the magnetic scale frame 3. One end of the linear magnetic scale is fixed to the magnetic scale frame and its other end is slidable along the inner surface of the hollow guide shaft which is coaxial with the-linear magnetic scale. The overall length of the magnetic scale apparatus is thus reduced to obtain a compact apparatus. Since the hollow guide shaft is coaxial with the shaft of the linear magnetic scale, the relative positional relationship between the hollow guide shaft and the linear magnetic scale is kept constant, even if the hollow guide shaft is inclined, thereby greatly reducing measurement errors. <IMAGE>
Patent GB-2198101-A (GB)
Title: Articulated oar
Inventor: WROE STANLEY
IPC: B63H16/04
Filed: 1986-11-08
Abstract: , An articulated oar which is so constructed that its blade 7 operates at all times at right angles to the keel line of a boat. This is achieved by securing the blade 7 at right angles to a follower 5 which pivots on a vertical axis on the outboard end of the loom 3, and whose attitude is controlled by a messenger 4 of the same length as the loom 3. Inboard ends of loom 3 and messenger 4 are secured to a leader 2 of the same length as follower 5: thus the four components loom 3 messenger 4, leader 2 and follower 5 form the four sides of a flexible parallelogram. Since the leader 2 is attached to the boat parallel to the keel line, the follower 5 will be maintained parallel to the keel line also, and the blade 7 will at all times operate at all times at right angles to the keel line. <IMAGE>

Title: Sprinkler
Inventor: RUSCH HANS-JOACHIM
IPC: A62C37/10
Filed: 1986-12-19
Abstract: The present invention comprises a sprinkler comprising:  a port (34); a rigid and breakable body (4) which whilst intact is capable of sealing the port (34) and which when broken would no longer seal the port (34); a breaking means (5) which, when actuated, can break the rigid and breakable body (4); and a temperature-dependent actuating means (6), (8) to (12) which, when it attains a predetermined elevated temperature, can actuate the breaking means (5); the arrangement being such that, in use, when the predetermined elevated temperature is attained, the actuating means (6), (8) to (12), actuates the breaking means (5) which causes the body (4) to break, thereby unsealing the port (34). The body (4) may be a hollow glass drum (4) which is filled with metal filaments arranged loosely inside as the breaking means (5). The actuating means (6), (8) to (12), may comprise a spring plate (8) which releases an impact spring (11) at a predetermined temperature, which strikes a small metal tube (6) filled with an impact-sensitive mass causing ignition of the metal filaments (5) and bursting of the glass drum (4). <IMAGE>

Title: Propulsion control system for a motor vehicle with all-wheel drive
Inventor: KROHN HELLMUT
IPC: B60T8/58
Filed: 1987-04-13
Abstract: In a propulsion control system for a motor vehicle which has a permanently balanced all-wheel drive, the drive slip threshold, at which the control responds in the sense of a baking action, is increased as a function of the velocity and decreased as a function of the transverse acceleration. The acceleration thresholds, at which the control responds, are lowered as a function of the transverse acceleration. In the case of travel in a straight line, the lowest of the wheel peripheral velocities is taken as the reference velocity relative to which the drive slip thresholds are fixed; in the case of travel in a curve, the average of the wheel peripheral velocities of the left-hand side and right-hand side vehicle wheel is taken as the reference velocity for the vehicle wheels on the left-hand side and the right-hand side of the vehicle, respectively. From the time to at which the control at one of the vehicle wheels comes into operation, the velocity of this vehicle wheel is updated in accordance with the expression   <IMAGE> and, at this value, is taken into account in the formation of the reference velocities. The vehicle longitudinal acceleration b is continuously determined by means of a longitudinal acceleration sensor; in order to achieve optimum driving stability, additional control signals for the initiation of a torque reducing action in the drive unit of the vehicle are generated by analysing the output signals of a transverse acceleration sensor, a curved travel sensor and the longitudinal acceleration sensor. <IMAGE>

Filed: 1987-04-16
Abstract: A cavitation nozzle 1 for use in eroding a solid surface with a pressurized fluid jet comprises a divergent inlet portion 10, a convergent portion 13, and an outlet portion 12. The convergent portion has a semi-apex angle of from 35 to 40 degrees, preferably from 37 to 38 degrees, and a surface substantially free of irregularities and discontinuities, preferably being finished to a tolerance of 0.025mm. A method of eroding a solid comprises the steps of forming a cavitating fluid jet by directing a flow of pressurized liquid through the nozzle 1 so as to form vapour bubbles or pockets in the liquid flow, and impinging the resulting multiphase fluid jet against the solid at a distance from the nozzle outlet portion at which the vapour bubbles or pockets collapse upon impact with the solid. The nozzle is suitable for sub- sea operation. <IMAGE>
