Title: Splint and stretcher
IPC: A61G1/01
Filed: 1979-03-13
Abstract: A blank for a splint or stretcher of corrugated plastics material has a panel 12 which on folding forms a base 22 and outer sidewalls 24, 26, and an extension panel 14 which forms an extension base 40 and extension walls 42, 44. Portions 48, 49 are pressed out on assembly and tabs 31, 32 engage slots 58, 60 to hold the panels 14 and 10 in a selected orientation thus providing an arm splint. Panels 14 and 10 may alternatively be kept aligned and extension 82 folded at fold line 72 and kept in position by locking panels 84 and 86 thus providing a splint for a leg. A panel of the same shape and larger dimensions, if only the sides 42, 24, 84; 44, 26, 86 are folded, may be used as a stretcher. The plastics material consists of two spaced apart sheets joined by longitudinal ribs and is substantially transparent to X rays. <IMAGE>

Title: A rotary cutting tool with inserts
IPC: B23B51/10
Filed: 1979-03-27
Abstract: A rotary cutting tool e.g. facing or boring tool has a body around whose cutting end there is removably held a circumferential succession of flat- flanked indexable cutting blades 13. The cutting edges of the blades extend generally radially of the tool body. Each blade is removably held in an associated accommodating recess 17, 18 by a screw 19 which enters the cutting end of the body to run down a screw-threaded bore 16 which extends along the body. As the screw is driven into the body, it bears progressively harder with a side of its head against an adjacent flank of the blade to wedge the opposite flank firmly against the side of its accommodating recess. The screws may run parallel to the blade flank, may bear against a reaction-absorbing surface with a tapered headside surface before bearing against the blade flank, or may be spherically-headed. The body may have a pilot 24 protecting inner blade corners. The boring tool blades are outwardly adjusted by a conical surface of a pin 28. <IMAGE>

Title: Snap-Fit Closure
IPC: B65D41/18
Filed: 1979-04-11
Abstract: A snap-fit closure comprises a crown 11 and a depending skirt 12 having on an integral surface, an inwardly projecting circumferential bead 13 and an integral sealing ring 15 juxtaposed the crown and adapted to co-operate with the rim 22 of a container neck 20. The closure is formed of a resilient elastic material and the spacing between the plane of the bead and the plane of contact of the container rim with the sealing ring 15 is such that on application of the closure to the container using a pressure member (30), Figure 1 (not shown) the skirt is stretched axially of the closure to effect interengagement between the bead 13 on the skirt with the projection 23 on the container neck, whereby the sealing ring 15 is maintained in compression due to the elasticity of the skirt. The bead 17 may be apertured to permit the pressure of any contents to act on the back of the sealing ring 15, increasing the sealing effect. <IMAGE>

Title: Electrical circuit for braking an AC electric motor
Inventor: ALCOCK JOHN MALCOLM
IPC: H02P3/22
Filed: 1981-10-27
Abstract: A capacitor 1 is arranged for connection across a first winding of the motor 10 and first and second thyristor switches 2a and 2b are connected across the second and third windings. A control circuit 4 controls the first and second switches to short- circuit the respective second and third windings. A circuit 3a detects when the voltages across both the second and third windings are negative and enables circuit 3b to provide a first control signal to the control circuit 4 when the voltage across the second winding becomes a small positive voltage and provides a second control signal to the control circuit 4 when the voltage across the third winding becomes a small positive voltage. After connection of the capacitor across the first winding the second and third windings are short-circuited at the appropriate times in the order to provide optimum braking. <IMAGE>
