Abstract: The working tool consists of a hollow rotation symmetrical shell within a rotating cylindrical casing on a vertical or slightly sloping shaft with an internal pressure spring forcing the portion of dough down onto teh working surface of the drum which rotates at constant speed and direction past the tool station. Two trap doors are hinged about a common axially parallel edge on the periphery of the drum, the trailing door being spring loaded into the closed position, being opened by the cam and follower into the open position immediately in advance of reaching that tool station to form a pocket into which a portion of dough is dropped by a synchronised flap valve at the base of the feed hopper. As synchronised flap valve at the base of the feed hopper. As it reaches the tool station, this trailing trap closes up to the drum surface and the dough is rolled into a ball and worked during the continued rotation of shell and drum until the leading trap, which is normally spring loaded open but is closed by a cam until just before it reaches the tool station opens and allows the ball to drop into the pocket so formed and clear the rim of the shell and its housing. The leading trap is then closed by a further cam to expel the ball onto a separate conveyor.

Title: Polyethylene contg. homogeneously distributed additives - by high speed mixing of liquid additives with heated resin
Inventor: HEIL FRANK
IPC: C08J3/20
Filed: 1973-10-31
Abstract: Prodn. of polyethylene contg. homogeneously distributed cross-linking aids and/or antioxidants comprises heating polyethylene granulate to 85-95 degrees C in a fluid mixer at a high level of revs. per min., adding the additives in liquid form, then further heating up to 110 degrees C, and finally cooling immediately to 70 degrees C with further stirring. A suitable cross-linking aid is triallyl cyanurate (TAC) and pref. antioxidants are aromatic amines, phenols or organic phosphites. By using the mixer at about 3000 rpm the additives are worked into the granulated resin bodies without the surface becoming greasy or moist. Amts. up to 5% TAC can be added. Using liq. TAC mixed with highly dispersed silicic acid in ratio of 2:1, then 10% TAC can be worked in. If antioxidant is added simultaneously in ratio 1:1 then only a max. of 4% TAC can be added without effecting processing props. Cross-linked polyethylene is useful as insulation, for electric cables. The method gives homogeneous distribution of additives at low concn. as can be demonstrated by the even distribution of a slightly coloured additive.

Title: Tubeless tyre with sidewall reinforcing - having ply layer secured between reinforcing rings holding tyre to rim
Inventor: PAKUR HENRYK
IPC: B60C9/02
Filed: 1974-02-22
Abstract: The side walls of the tubeless tyre are fitted with reinforcing rings running around the edge of the tyre. These hold the tyre on the wheel rim. The ply insert layers are secured in the edges of the tyre by dividing the reinforcing rings into two layers, with each layer having the same shape and strength. The ends of the play layers are clamped between the two sets of reinforcing rings and thus eliminate the need for looping the ends of the layers over the rings. The loops could otherwise lead to tyre walls splits and reduce the flexibility of the tyre.
