Patent GB-2058940-A (GB)
Title: Radial impeller
IPC: F04D29/28
Filed: 1980-07-21
Abstract: The invention is applicable primarily to double-entry fans or blowers without an end plate and has the aim to make the junction between the blades and drive element 3 elastic and secure. Clamping of the elastic part 5 of each blade in the drive element occurs in a curved channel 4 subdivided into two regions, in one of which 6 the shapes of the channel and of the elastic part correspond. The locking against axial displacement of the wheel rim also occurs here. in the other region 7 the curved channel widens. The elasticity of the blades operates here. <IMAGE>

Title: Checking vehicle headlamp alignment
IPC: B60Q1/06
Filed: 1980-10-17
Abstract: A screen (4) is provided in front of a vehicle (2), and a semi-transparent mirror (3) is provided halfway between the vehicle and the screen. The mirror (3) is inclined at an angle  alpha  away from the vehicle, and forms a virtual image (10b) of the vehicle headlamp (9b). The line joining the headlamp and its image is inclined at the angle  alpha  to the horizontal, and defines the required direction of part of the headlamp beam, such as its upper cut-off. The part of the beam which passes through the mirror (3) forms an illumination pattern on the screen (4), and the relative position of this pattern and the virtual image (10b) indicates whether the headlamp alignment is correct. The apparatus is preferably provided at a filling station. <IMAGE>

Patent GB-2076182-A (GB)
Title: Fluid Control Valve
IPC: A62C31/24
Filed: 1981-04-30
Abstract: A pair of identical fluid control valves 13 and 14 control the supply of a pressurised working fluid from a source 18 to the two sides 8A, 8B of a double-acting hydraulic actuator 8. Each valve has a chamber 33 with three ports 13A/14A, 13B/14B and 13C/14C opening to it. The ports 13A/14A and 13B/14B at the opposite ends of each chamber can be closed by respective balls 36,32 biased by springs 37,34 against their seats 38,35. The ports 13A/14A are connected to the source 18 of pressurised working fluid which fluid can unseat the balls 36 and flow to the chambers 33; the ports 13B/14B are connected to an unpressurised drain 19; and the ports 13C/14C communicate the pressure in the chambers 33 to the respective sides of the actuator 8. Respective pistons 30 are provided to control the balls 32 in response to signal fluid pressures in lines 26A and 26B, and when a signal pressure of sufficient strength is applied to one of the pistons 30 it unseats the associated ball 32 to connect the corresponding chamber 33 to the drain 19. At the same time the ball 32 urges a rigid spacer 41 against the associated ball 36 to restrict communication of the corresponding chamber 33 with the source 18. There is thus a drop in pressure within that chamber 33 and hence a pressure difference exists across the actuator under which it moves to perform its corresponding function. <IMAGE>

Title: Tethered kite sailing rig
Inventor: MORLEY DR THOMAS SELWYN
IPC: B63H9/06
Filed: 1982-02-08
Abstract: A trapezoid shaped sail is symmetrical about its vertical axis and when set, has all four sides free - that is unattached to stays or spars. It is considered to have a head, foot and a port and starboard luff (superiorly) and leech (inferiorly) separated by shoulders. These attach to the extremities of the arms of a folding spar where a port and a starboard trimming sheet attach also. The spar is expanded by a setting line at a predetermined height when the sail leeches are fairly taut, thus supporting the sail and helping it to fill. This spar is attached only to the raising loop, which replaces the forestay, the sail shoulders, and the setting line. The upper end of the raising loop (B) divides into two wires which attach to the spar's arms; these wires steady the spar during the raising and lowering of the collapsed sail. <IMAGE>

Filed: 1982-05-24
Abstract: A dispenser 10 for a roll of material wherein the spindle 16 is so shaped and/or arranged as to engage the internal surface of a roll over only part of the length of the spindle. Thus the roll can be turned on the spindle without undue resistance but on the other hand some frictional resistance is provided which prevents the roll "freewheeling" around the spindle. The spindle 16 either carries or is formed with one or more rings, or has a wavy or zig-zag shape the points of which zig-zags or waves engage the inner surface of the roll or core. <IMAGE>
Patent GB-2103716-A (GB)
Title: Hydraulic accumulator
Inventor: LEWIS MICHAEL ANDREW
IPC: F16L55/054
Filed: 1982-06-23
Abstract: An accumulator arrangement comprises a pressure transfer device having a body 1 and inlet and outlet ports 2 and 3 at opposite ends thereof which are formed for connection in a pipeline of a food processing plant. A resilient rubber sleeve 5 is disposed within the body 1 and liquid is disposed in the space defined between body 1 and sleeve 5. A port 7 leads from the body 1 to a conventional accumulator 9. Rises and falls in the pipeline pressure cause the sleeve 5 to extend or collapse which in turn results in liquid being pushed into or received from accumulator 9 until equilibrium is again reached. The smooth internal appearance of sleeve 5 minimizes the tendency of food particles to lodge therein. Other types of transfer barrier may be used depending on the application. <IMAGE>

Patent GB-2142188-A (GB)
Title: Electrical relays
Inventor: ELDRIDGE P D
IPC: H01H51/22
Filed: 1983-06-25
Abstract: The movable armature (2) of a relay extends through a coil (1) and is arranged to operate contact sets (3) via insulating stirrups (5) connected to movable contacts (6). The contact force of the contact sets (3) is enhanced by means of a permanent magnet (10) and two pole pieces (8,9) coupled thereby. In a monostable version (as illustrated) the areas of the pole pieces (8,9) via which coupling to the armature (2) occur are different in size, so that when the coil (1) is de-energised the armature (2) will always restore to the same position (as illustrated). In a bistable version the pole piece coupling areas are the same so that the armature is held in its last set position upon coil de-energisation. <IMAGE>

Title: Balance weights
Inventor: WELSH DAVID E
IPC: B23P6/00
Filed: 1984-09-25
Abstract: An improved balance weight construction and a method of securing such a balance weight 12 to a drive shaft 10 or other tubular body are disclosed. A generally cylindrical balance weight 12 is formed with a curved end surface which conforms to the outer surface of the drive shaft 10. The balance weight and drive shah are typically formed of dissimilar materials, such as steel and aluminium, respectively. The balance weight 12 has a coaxial aperture 14 formed therethrough and a plurality of radially-extending grooves 16 formed in the curved surface thereof which connect the aperture 14 with the edge of the surface. While the balance weight is maintained against the drive shaft at a predetermined location satisfactory for balancing the drive shaft, an adhesive material 18, such as molten aluminum wire, is supplied within the aperture 14 so as to form a spot or rivet-type weld. The radially-extending grooves 16 provide passages which allow gases within the aperture to escape, thereby promoting the smooth flow of molten aluminum into the aperture and increasing the reliability of the weld. <IMAGE>

Title: Remote control system
Inventor: HOLE ROBERT DAVID
IPC: H04M1/652
Filed: 1985-01-08
Abstract: An electrical device, such as a central heating circuit, is controlled by a switch 17 operable in response to impulses on line 11 from the rewind motor of the message medium in a telephone answering machine. The pulses are fed through a priming circuit 13, 14, 21, 22 which causes the switch to be operated after alternate rewinds of the message medium starting with the first. A tone generator 19 is provided to indicate the status of the switch 17, which tone is transmitted to the telephone line to be heard with the play-back of recorded messages. Interrogation of the telephone answering machine involves two rewinds of the play-back medium, and it is arranged that the first rewind causes the switch to change state and the tone to stop or start generation, the second rewind of each interrogation being ignored. <IMAGE>
