Title: Constant velocity joints
Inventor: KERR MICHAEL
IPC: F16D3/20
Filed: 2007-08-16
Granted: 2011-08-10
Abstract: A constant velocity (CV) joint assembly comprising a CV joint and an input member is disclosed. The CV joint that has a cage and a gear between which rotational drive can be transmitted. The input member is connected to the cage of the CV joint for transmission of rotational drive about an axis from an external component to the CV joint. The rotational drive is transmitted between the cage and the input member through interacting drive faces that are disposed in a plane that is generally parallel to the axis. The cage and the input member are retained in interconnection by fastening means that are not responsible for transmission of rotational drive between the cage and the input member. By separating the task of transmission of torque and retention of the connection between the cage and the input member, the fastening means required to perform the latter task can be comparatively light. An increase in torque capacity of the CV joint assembly does not lead to a corresponding increase in the strength requirement of such fastening means. The orientation of the drive faces ensures that there is minimal axial force between the cage and the input member.

Granted: 2011-05-18
Abstract: A make-up kit comprises a plurality of containers (10, 20, 20a 30, 40, 50, 60) having top surfaces made up of different integer numbers of substantially identically shaped units (15a, 15b, 15c, 15d) and bottom surfaces made up of corresponding numbers of substantially identically shaped units (17a, 17b, 17c, 17d), peripheral areas 14 of the top surface units (15a, 15b, 15c, 15d) being of complementary shape to peripheral areas 14 of the bottom surface units (17a, 17b, 17c, 17d), so that each container is separably interengageable with at least one other of the containers above or below, by interengagement of the complementary shaped unit peripheral areas 14, 16. In this way large or small numbers of identical or different units may be connected together in a large number of different configurations; each differently shaped container effectively forming a differently shaped, but mutually compatible, building block.

Title: Liner and re-enterable closure assembly
IPC: H02G15/18
Filed: 1982-01-28
Granted: 1985-03-13
Abstract: A re-enterable closure assembly for enclosing an elongate substrate such as a telephone or power cable, has an outer sleeve, preferably heat recoverable, and an inner liner to protect the cable against heat and mechanical damage. The liner has two major parts, a support and a disposable layer, thus allowing the outer sleeve to be removed, for repair etc, without damaging the liner. This could not easily be achieved in a one piece liner since a bond generally must be formed between the liner and the outer sleeve to prevent wicking of moisture vapour.

Title: Friction welding
Inventor: SEARLE JOHN GILBERT
IPC: B23K20/12
Filed: 1989-09-15
Granted: 1992-04-22
Abstract: A friction welder has a reciprocator (1) with two chambers (7 and 8) each containing hydraulic fluid and separated by a dividing wall (6). A piston (14) on a driven rod (13) is slidable in a hole in the dividing wall and supports a carrier (28) to which a first component (36) is secured. Tow additional rods (9 and 10) extend through the chambers. Enlarged portions (11) thereof extend through holes in end walls (4 and 5) of the chambers. The additional rods are caused to reciprocate with fixed amplitude by Scotch cranks (23 to 26, and 31) driven by a motor (30). The relative phases of the Scotch cranks can be varied by axial movement of a sleeve (35) which engages splined shafts of the cranks, one of sets of splines (35) being helical and the other straight. When the additional rods reciprocate in unison they cause local variations in the interior space of the chambers which cause reciprocation of the piston. The amplitude of reciprocation of the piston is less than that of the additional rods but the force exerted is greater. The first component is held in frictional contact with a stationery second component (37) so that frictional heat is generated between them. When the cranks are 180 DEG  out of phase the piston ceases to move and the components become welded together. Reciprocation of the piston and associated parts is balanced by a balancer (2) somewhat similar to the reciprocator, while reciprocation of the additional rods and their extensions (16 and 17) in the balancer are balanced by pivoted counterweight (46).

Granted: 1986-09-10
Abstract: The method is for mending a veneer sheet (1) having a defective portion. An incomplete veneer sheet and a sheet of mending material (2) are laid one on top of the other. The sheets are cut through by a single stroke of an annular cutting tool (4) such that the defective portion of the veneer sheet is cut-out. A plug (2a) having a same size and shape as the cut-out defective portion is cut from the sheet (2). The cut portions are retained in the annular cutting tool until the plug is shifted into a plane in which the veneer sheet extends. At the same time, the cutout defective portion (1a) is routed out from the veneer sheet. Then, when the cutting tool is removed from the sheets (1,2), a mended veneer sheet results.
