Patent GB-2056063-A (GB)
Title: Stabilized platforms
IPC: G12B5/00
Filed: 1980-06-30
Abstract: The invention comprises a stable platform mounted on an orthogonal gimbal system (12) having a roll gimbal (14) and a pitch gimbal, there being a counter weight (15) suspended from the gimbal system (12) to accurately balance the total load carried by the system about both the roll and pitch gimbals. The pitch gimbal is mounted on the roll gimbal (14) and carries both the load (11) and the counter weight (15). The platform and load (11) remain, ideally, in the horizontal plane eliminating the need to accelerate the inertia of the system. A servo system torque is provided by motors (16) and tachometer-synchro assemblies (17) to maintain a vertical reference by overcoming gimbal bearing friction. <IMAGE>

Title: A joint
IPC: A47D7/00
Filed: 1980-07-21
Abstract: A joint for a collapsible cot includes a pivotable strut member 2 and an elongate pivotable frame member 3, which members are pivotable between an erected position in which they are at an angle to one another and a collapsed position in which they lie substantially parallel to one another. The members are separately pivotably mounted within a moulded plastics body 4, and a detent 13 is provided against which the strut member engages in the erected position to prevent pivoting of the strut member to the collapsed position, which detent is associated with the elongate pivotable frame member 3 whereby when that member is moved from the erected to the collapsed position the detent 13 is released from engagement with the strut member 2 so that the strut member can be pivoted to the collapsed position. <IMAGE>

Title: Vibration-dampening Flexible Coupling
IPC: F16D3/74
Filed: 1980-08-27
Abstract: A flexible coupling member (10) is constructed from a length of elastomeric cylindrical tubing. The opposite ends of the tubing are closed by axially spaced ribs (12, 13) positioned at right angles, and the outer surfaces of the flexible coupling between the ribs are bounded by smooth warped surfaces. The ribs (12, 13) are preferably received in grooves (14, 16) in blocks (15, 17). The ribs (12, 13) may incorporate a check valve for pressurizing the tube to increase torque capacity. Alternatively the check valve may be incorporated into the tubing so that the coupling need not be dismantled for pressurization, in which case more than one check valve may be used to avoid imbalance. The 'tubing' could alternatively be solid. <IMAGE>
Patent GB-2082980-A (GB)
Title: Manually Pushable Wheeled Appliance
IPC: B60B33/00
Filed: 1980-09-04
Abstract: A wheeled step ladder has a rectangular base frame 10 with a pair of permanent ground-engaging wheels 15 at the corners of the front end and a pair of stands 11 at the corners of the rear end. A further pair of wheels 25 are also provided each adjacent a respective leg 11, these latter wheels being mounted for vertical movement relative to the frame 10. In the rest position of the ladder, substantially the entire weight of the ladder is distributed between the legs 11 and wheels 15, the wheels 25 resting only lightly on the ground. The legs 11 thus constitute a brake by virtue of their friction against the ground. In order to bring the ladder to a mobile condition, a lever 35 is manually rotated so as to exert via a cam a downward force on the wheels 25, and the resultant upward reaction force on the ladder framework raises the legs 11 out of contact with the ground in opposition to the weight of the ladder. Upon release of the lever 35, the ladder automatically reverts to its rest condition. <IMAGE>

Patent GB-2057654-A (GB)
Title: Ladle heating system
IPC: C21C7/00
Filed: 1980-03-18
Abstract: Prior to the receipt of a charge of molten metal, a ladle (11) is heated by a direct flame, by applying a seal (21, 225) to the rim of the ladle and directing air through a heat exchanger (29, 229) and to the ladle, mixing fuel with the air and igniting the mixture and directing the flame in to the ladle chamber, and exhausting the gases of combustion from the ladle chamber back through the heat exchanger. The seal (21, 225) applied to the rim of the ladle comprises a network of refractory fibers mounted in a common plane. In one embodiment the fibers are formed in modules (55) and the modules each comprise a rectangular block formed in an accordion folded arrangement, and the modules are mounted with their folded edges (59) exposed, and with the folds of each module extending at right angles with respect to the folds of the adjacent modules.
Patent GB-2092702-A (GB)
Title: Improvements in or relating to screw and nut actuators
IPC: F16H25/20
Filed: 1981-02-07
Abstract: A screw and nut actuator has an actuating rod 15 carried by a nut 14 non-rotatably engaged with a lead screw 7. Rotation of the lead screw 7 causes relative axial movement of the nut 14 and hence of the actuating rod 16. The lead screw 7 is so mounted that it permits tensile loading but prevents compressive loading. This may be accomplished by holding opposite ends of the lead screw 7 against movement together but permitting them to move apart. Alternatively or additionally the lead screw 7 may be pretensioned to avoid compressive loading. The nut 14 may be mounted on four lead screws 7 equiangularly arranged about the axis of a motor drive shaft 23. <IMAGE>

Title: Target for magnetically enhanced sputtering of chromium-iron alloy
Inventor: SUGDEN GEORGE BARRY
IPC: C23C14/34
Filed: 1981-07-18
Abstract: The target comprises a non-magnetic base of either stainless steel or titanium, plated with chromium (between 60% and 80% of its effective area) and studs of titanium (when the base is stainless steel) or stainless steel or iron (when the base is titanium) are welded to the unplated parts. The base may be tubular or planar and, when tubular, the plating may be internal or external. In one particular advantageous form the effective percentage areas of the target contributed by the metals is 76% chromium 19.7% stainless steel and 4.3% titanium. If desired, when the base is stainless steel, the titanium studs can be omitted. Targets of this form have been found to produce in use a chromium finish of the desired quality, clarity and brilliance.

Title: Carbon deposition inhibition
IPC: C23C8/14
Filed: 1982-04-30
Abstract: An operational problem of Advanced Gas Cooled Nuclear Reactors is the formation of carbonaceous deposits on the surfaces of the corrosion resistant heat conducting containers for the nuclear fuel. The heat transfer characteristics of the containers are thereby adversely affected. In the invention, the containers are fabricated from a Cr-containing steel and have a surface oxide layer which is substantially free from Fe and Ni provided by annealing in an atmosphere of low oxygen partial pressure such as an atmosphere of hydrogen saturated with water. Test experiments have shown that such containers exhibit far less tendency to be subject to carbonaceous deposition than equivalent containers whose oxidised surfaces contain Fe and/or Ni.
