Patent DE-3424550-A1 (DE)
Title: Coolant feed device
Inventor: HEIMANN BERNHARD DIPL ING
IPC: B21B45/02
Filed: 1984-07-04
Abstract: It is known to equip cooling sections for bar-shaped rolling stock with coolant feed devices which have a cooling tube surrounding the rolling stock and acting as a nozzle and an annular housing which surrounds the cooling tube, forming an annular space, and is connected to a coolant source via a feed connection branch. Since the coolant entering through the feed connection branch passes directly to the cooling tube, the associated asymmetric incident flow has a disruptive effect during the operation of the cooling section, particularly at relatively high pressure of the coolant. The invention proposes the use of a tubular deflection unit (6) which exhibits a clearance within the annular housing (2) - also having a clearance with respect to the coolant tube (central tube portion 1b) surrounded by it - and the length of which is such that it screens off the cooling tube from the outlet opening (3a) of the feed connection branch (3) and thereby forcibly brings about uniform tangential flow onto the cooling tube. <IMAGE>

Title: Process for casting ceramic mouldings under the effect of mechanical vibrations
Inventor: FAUSTMANN REINHARD
IPC: B28B1/26
Filed: 1984-08-04
Abstract: Process for casting ceramic mouldings under the effect of mechanical vibrations in order to prevent the defects typical of the gravity casting process, such as the formation of casting grooves, streaks, casting marks and cracks. According to the invention mechanical vibrations are applied to the slip by a device during the casting process and subsequently thereto in order thereby to prevent the solid particles from forming distinct textures until the start of body preparation. Essential to the invention is the fact that the slip is set into vibration "from the inside outwards" and the tuning of the excitation frequency and the vibration amplitude to the constructional design of the device which is immersed in the slip and transfers low frequency mechanical vibrations in the casting mould to the slip.

Title: Connecting device
Inventor: YOKOYAMA HIDEKI
IPC: H01R4/22
Filed: 1984-09-14
Abstract: A connecting device contains an insulating housing (11) in the form of a small box which is provided with a base and in which holes (14) are provided in the base for wire ends to be pushed into. A conductive contact device (21) in the form of a polygonal tube is pushed into the housing (11) such that one open end is located close to the base and the other open end is located close to the open end of the housing (11). A plurality of conductive spring devices (31) are fitted inside the contact device (21) such that they extend between the base and the open end of the housing (11) and are in each case located in a line with the insertion holes. The spring devices (31) jointly press wire ends which are to be connected into contact with the contact device (21) when these wire ends are pushed in between the spring device (31) and the contact device (21), and, at the same time, they prevent the wire ends being pulled out of the contact position. A cover (41) is mounted on the open end of the housing (11). The individual components are produced in a simple manner and are fitted in the same direction by pushing them into the housing, so that a noticeable improvement is achieved in the productivity of the connecting device. <IMAGE>

IPC: H01H50/02
Filed: 1984-11-03
Abstract: The invention relates to electrical switching apparatuses, especially electromagnetic contactors, auxiliary contactors and their auxiliary switches, in the case of which it is intended to achieve a constant movement/force characteristic. The object is to use switching apparatuses having normally-closed switching systems, in which means are provided for supporting the contact compression spring on an opposing bearing of the housing, even in the case of switching apparatuses having a longitudinally split housing.

Title: Process for the enzymatic/microbial production of sour cream butter
Inventor: HUELSEN ULRICH DR ING
IPC: A23C15/12
Filed: 1984-11-20
Abstract: The invention relates to a process for the enzymatic/microbial production of sour cream butter, in which the cream obtained by separation passes through the process steps pasteurisation, cream ripening, churning and final ripening. 
<??>The aim of the invention is to develop a process in which the configuration of the cream ripening process and the feed of the lactic acid bacterial cultures proceed in such a way that the cream ripening times ensure a continuous process from the separation to the completion of the sour cream butter complying with the standards. 
<??>According to the invention, this is achieved in that the cream obtained by separation is inoculated with 5% of an intensive acidification lactic acid bacterial culture, which leads to a specific spontaneous pre-acidification. On reaching the pH of 5.5-5.8, the pre-acidification is interrupted and the cream is pasteurised and then cooled to a temperature from 3-20 DEG C and held for 20-30 minutes. It is then adjusted to churning temperature and made into butter in known butter making machines. 6% of an aroma-intensive lactic acid bacterial culture is then kneaded into the butter. The butter is packaged and stored for final ripening for 24 h at 3-5 DEG C.
