Title: Clamps for tubular scaffolding
Inventor: THORLEY DAVID EDGAR
IPC: E04G7/18
Filed: 1983-08-11
Abstract: A cover 2 of a clamp for tubular scaffolding is formed from sheet metal into channel section, free edges of the flanges of the channel section providing an arcuate recess to engage the scaffold tube. The web of the channel section widens and the spacing apart of the flanges consequently increases towards the middle of the arcuate recess from adjacent each end of the cover. This wide spacing of the flanges reduces rocking movement between the clamp and scaffold tube. The local widening can be provided without requiring extra material. The channel section is continued and again similarly locally widened at one end 2'' which is bifurcated to receive a clamp bolt 3. <IMAGE>

Title: Door or gate obstruction control
Inventor: SEIDEL RAYMOND LESLIE
IPC: H02H7/085
Filed: 1985-11-25
Abstract: An obstruction sensing and control arrangement for door or gate opening-closing mechanism compares at CB the rate of change of a predetermined characteristic of the motor M with a preset rate of change and if exceeded stops or reverses the motor M in the opening/closing mechanism. The characteristic preferred is motor body temperature which is monitored indirectly. The control arrangement also includes a back up static control threshold to sense a second static operating characteristic of the motor and a second comparator CA means set at a preset threshold level to stop or reverse the motor.

Title: Method of making a potentiometer
Inventor: DISNEY FREDERICK ERNEST
IPC: H01C10/32
Filed: 1986-04-01
Abstract: In a method of making a rotary potentiometer in which a rotary actuator (2) is arranged to cause a wiper on a carrier in a thermoplastics housing (1) to traverse a resistance track in the housing (1), a thermoplastics member (8) on the surface of the housing (1) is arranged for rotation about the axis of rotation of the wiper carrier. With the actuating means (2) in contact with a stop (12) on the member (8), relative rotation is effected between the member (8) and the housing (1) until a desired output voltage is obtained at a terminal connected to the wiper. The member (8) is then secured to the housing (1) by passing a current briefly through a wire (11) at the interface therebetween to locally melt the thermoplastics material and fuse the parts (1, 8) together. Holes (10) in the member (8) may be slotted and are aligned with slots in the housing (1) to enable the potentiometer to be screwed to a support. <IMAGE>
