Abstract: The invention relates to a vehicle tyre, which has a tyre carcass 6 and at least one surface covering 20 composed of two grades of rubber, the surface tread on the surface covering being formed by grooves 3 and by the separate tread bodies 5. Of the grades of rubber, either the harder grade 1 lies as a layer against the carcass and the more flexible grade 2 lies outside, so that it forms the tread surface 4, or alternatively the more flexible grade 1 lies as a layer against the carcass and the harder grade 2 lies outside and forms the tread surface 4. Some of the tread bodies are of a type 11, which in the direction of its height H1 is composed both of the first grade of rubber 1 of the said type on the carcass side and of the second grade of rubber 2 of said type on the tread surface. Some of the tread bodies are of a type 12 which in the direction of its height H2 is composed in the main of the second grade of rubber 2 on the tread surface. The height H1 from the bottom 7 of the grooves and up to the tyre periphery of the tread bodies in the first type is essentially greater than the height H2 of the tread bodies in the second type. <IMAGE>

Abstract: The subject matter of the invention is an item of furniture for computer equipment, the keyboard table panel of which is pushed in under the table panel. The furniture side panels with shelving level can also be swivelled under the table panel. In this way the working area with a table panel of 1700 mm x 700 mm is folded to an area of 700 mm x 500 mm. There is also space under the furniture side panels, for example, for printers, files and various accessories. When closed, the furniture harmonizes with the other furnishings, with nothing externally that might suggest a computer. All that can be seen at the back of the furniture is an electrical lead and a telephone line. The furniture is easy to move thanks to the castors, of which the front ones are pivotable and lockable. It takes less than 10 seconds to open the furniture to a substantial workstation, but short operations can be performed by rolling up the roll front and pulling out the keyboard. In office spaces folding furniture looks neat and makes tidying up easier. <IMAGE>

Title: Improvements in or relating to tension devices for yarn and like winding and like machines
IPC: B65H59/24
Filed: 1940-01-19
Abstract: 538,126. Winding yams &c. ABBEY, A. (Universal Winding Co.). Jan 19, 1940, No. 1227. [Class 120 (ii)] A device for tensioning yarn or the like in a winding or like machine comprises two opposed yarn-engaging elements between which the yarn is passed, one or both of the elements being constituted by a disc or discs or each disc having a face engaging the yarn with resilient tension-applying means which acts directly against the rim of the disc so that the rim transmits the tension-applying thrust and urges the disc towards the other disc or towards a support. As shown the device comprises a pair of cup-shaped discs 10, 11 having peripheral lips 20, 21 engaged by resilient discs 25, e.g. of rubber or fibre, one of the discs abutting against a washer 29 on, a dished bracket 18 fixed to the machine frame and the other disc being engaged by a thimble 28 on a spindle 27 passing through a hollow sleeve 12 fixed in bracket 18 and carrying the discs &c. The rod 27 has a hooked end 38 engaging a slot in the end of a lever 33 pivoted on the frame and adjustably connected by a rod 56 to an angular lever 53 having its other arm pivoted to the bent end 50 of a rod 49 the rod being adjustably connected to a bracket 46 secured to the counterweighted arm 6 pivoted on the cam shaft 4 of the machine and the end 50 being disposed on an elbow lever 48 pivoted on a fixed pivot 42; the arm 6 may as shown carry the reciprocating thread guide 5 or it may carry the bobbin being wound. The angle of the lever 53 is connected by a screw 52 to an arcuate slot in a tension lever 40 also pivoted on the end 50 of the rod 49 and by adjusting the screw 52 in the angular slot the initial pressure between the discs can be varied; as the frame 6 swings with the traversing thread guide 5 from the bobbin being wound the pressure between the discs is progressively reduced to maintain a constant tension on the yam. The elbow lever 48 is adjustably connected by a rod 43 with the bracket 46 and the rod is fixed to a weighted lever 41 pivoted on the pivot 42 so that as winding proceeds the pressure of the thread guide against the yarn being wound is progressively reduced due to the raising of the weighted levers. The discs &c. may be mounted on a fixed pin with one of the discs pressed against the other by a spring disposed between a washer abutting against the corresponding resilient disc and a collar adjustably fixed to the pin or the pin may be arranged vertically and carry disc weights pressing against the resilient disc. In a modification the resilient discs are replaced by spring metal spiders which are prevented from rotating on the carrying sleeve or pin.
