Title: Device for controlling the feed bank upstream of the roll nip of a calender
Inventor: SCHREITER CLAUS
IPC: B29C43/24
Filed: 1981-03-14
Abstract: The invention relates to a device for controlling the feed bank by means of measuring sensors for controlling the height, width and temperature of the bank. The aim of the invention is considerably to improve the product produced and the continuity of the calendering process. The object underlying the invention is to provide a control of the feed bank with which, in addition to the bank height, the width and temperature of the bank can be simultaneously registered and controlled. This object is achieved in that, for the independent control of a bank, four temperature sensors which are grouped into at least two pairs and are adjustable with respect to one another in a specific distance corresponding to the set-point limits, are arranged against the outsides of the bank, on a carrier adjustable by means of a guide and adjustment device, in a holder, so that, in the steady state, one temperature sensor of each pair dips into the bank whereas the second temperature sensor of the pair has no contact with the bank. The device according to the invention is used on calenders for processing plastic compositions.

Title: Method for producing a shaped support part for the connection of two or more asymmetrically designed flat radiators
Inventor: KOENIG HARRY
IPC: B21D53/02
Filed: 1981-04-09
Abstract: The invention relates to a method for producing a shaped support part for the connection of two or more asymmetrically designed flat radiators, in which the design of the particular clearance width is to remain unaltered and the profile of the reverse side is designed such that the necessary connections can be made in association with the support parts and a conventional attachment piece. The parts known hitherto are unsatisfactory, they are either too expensive or insufficiently accurate. The object is therefore to propose a support part of this type which guarantees a maximum degree of precision and a high degree of stability while at the same time avoiding metal-cutting work and additional welding work. The solution lies in the production of a shaped piece which is made of steel sheet by bending and partial reverse upsetting and whose blank, starting from an approximately square base area, has a tab on each side, and the part, after the blank is cut, is deformed in two or three operations into the body to be produced. The heating medium passes through an opening provided in the base of the shaped support part and disperses via lateral recesses.

Title: Ballcock
Inventor: HIRAKAWA MASAKATA
IPC: F16K5/06
Filed: 1981-05-29
Abstract: Ballcock with a ball which is arranged in a housing, is penetrated by a passage and can be rotated between an open position and a closed position to enable and shut off flow through the ballcock. A cavity which is present between the ball and the housing and in which a fluid or impurities might be trapped is filled with a highly polymeric material to an extent at least sufficient to ensure that the two openings of the passage through the ball can be closed in a sealing manner. By virtue of this arrangement, fluid trapped in the passage through the ball and in the cavity on closure of the cock is displaced and replaced by inflowing fluid when the ballcock is next opened and, as a result, the ballcock is kept free of impurities at all times.
