Title: Prepn. of microorganisms with constitutive acylase - by coupling DNA-fragment for acylase with a plasmid and introducing this to a beta:lactamase-free host strain
Inventor: WAGNER FRITZ PROF DR
IPC: C12N15/00
Filed: 1979-07-28
Abstract: Prepn. of microorganisms with constitutive acylase for clearage or synthesis of beta-lactam antibiotics comprises (i) removing the DNA-fragment for the acylase from the total DNA of an acylase- producing microorganism (ii) coupling this invitro on plasmids of high copying count (iii) adding this to a beta-lactamase-free prokaryotic host strain, selectively isolating and opt. mutagenising in vitro or in vitro to give a prokaryont with stable high constitutive acylase activity and opt. with modified substrate specifity. Acylases can be used in the prepn. of 6-aminopenicillanic acid or 7-aminocephalosporanic acid from beta-lactam-antibiotics, and in the reverse reaction, for the synthesis of beta-lactam antibiotics. The enzyme synthesis is constitutive, needs not indicator and, contrary to lactose and fructose leads to no metabolite depression. This improves recovery of the biocatalyst. The specific activity of the acylase is much higher than that of the original microorganism, so the reversal of the reaction (i.e. the formation of beta-lactam antibiotics) is much more efficient. The gene for the acylase is easily transferred to beta-lactamase free host organisms.

Patent DE-3118046-A1 (DE)
Title: Process for producing concrete components
Inventor: WAUHOP JUN BILLY JOE
IPC: C04B40/00
Filed: 1981-05-07
Abstract: The process for producing concrete components allows a part of the expended thermal energy to be recovered from the oven atmosphere during the setting of the concrete components and the use of the recovered thermal energy for preheating water for preparing the concrete mix, from which subsequently concrete components are produced, or for making up feedwater which is used for generating low-pressure steam; both uses are also possible. For the case where two or more ovens are operated simultaneously, a staggering in time is envisaged in which the oven atmosphere of high temperature from the oven which is being cooled, is mixed with the oven atmosphere of low temperature from the oven which is being heated, whereby thermal energy of one oven is recovered and utilised in the other oven, which overall reduces the energy consumption for the setting of concrete components. <IMAGE>

Title: Stopping device for the drive spindle of angle grinders or similar electric tools
Inventor: BRAUN ROLAND ING GRAD
IPC: B24B23/02
Filed: 1981-05-26
Abstract: The invention relates to a stopping device for the drive spindle of angle grinders or similar electric tools, comprising a stopping bolt which can be displaced, in the machine housing, radially with respect to the axis of the drive spindle, if subjected to the action of a restoring spring and if assigned at least one stopping cutout which is provided in the drive spindle itself or in a structural part which is fixedly connected thereto. It is intended to improve said stopping device such that the risk of the stopping bolt being switched on unintentionally is eliminated. This is achieved in that the stopping cutout in the drive spindle or in a structural part forming a unit therewith can be released or shut off, with respect to penetration of the stopping bolt, by means of a sleeve which is arranged, such that it can rotate and is secured against axial displacement, directly or indirectly on the drive spindle, is provided with a through-bore for the stopping bolt and has two stops to which a fixed stop is assigned. After rotation of the stationary drive spindle counter to its direction of rotation when operating, one stop comes to bear on the fixed stop, due to the sleeve being carried along by friction, and, when the drive spindle is rotating, the other stop runs onto said fixed stop, as a result of which the sleeve remains in its shutting-off position. <IMAGE>
