Title: Device for adjusting, measuring and testing rectangular flat cross-sections
Inventor: GLASS KARLHEINZ DIPL ING
IPC: G01B7/04
Filed: 1988-12-03
Abstract: The device relates to a device for adjusting, measuring and testing rectangular flat cross-sections. The aim is to improve the quality of measuring and testing and to reduce the work of preparation and setting up. The task consists in providing a device in which there is always a parallel arrangement of the test coils independently of the material thickness and the rolling material is guided exactly in the horizontal and vertical planes in the region of the test coils. This is achieved when an upper part which holds the upper test coil and vertical slideways is supported via a four-bar linkage (link quadrangle) on a bridge-shaped frame which is fastened at the lower part, and can be swivelled against an adjustable stop by means of a working cylinder pivoted to the lower part and to the four-bar linkage, and when the horizontal guides arranged in front of and behind the test coils are provided such that they can be adjusted symmetrically and side walls which can be folded (hinged) upwards are mounted between these guides. <IMAGE>

Title: Liquid cooling device
Inventor: BOEKEMEIER VOLKER DR
IPC: F28C1/12
Filed: 1988-12-16
Abstract: In a liquid cooling device (1) having a housing (2) and a fan (ventilator) (8), which is arranged in the housing (2) and is seated in a heatable bearing ring (10), the bearing ring (10) is subjected to the approaching liquid from a water distributor (5) via a heating conduit (12).

Title: Method for attaching a bypass fan gas-turbine engine to an aircraft
Inventor: NEWTON ARNOLD CHARLES
IPC: B64D27/18
Filed: 1989-01-26
Abstract: A bypass fan gas-turbine engine (12) on a supporting pylon (14) is rigidly connected via guide rods (18 and 20) and bolted flanges with metallic mutual contact, such that no relative movement can take place between them as a result of vibration. In contrast, the pylon (14) is mounted on the aircraft load-bearing structure (38 and 40) via connections which have elastic sleeves. The arrangement ensures greater robustness of the structure, consisting of the fan structure and the core gas generator. <IMAGE>

Title: Spinning mill transport - has trolley for conveyance of cops to other departments
Inventor: WEICH ROLAND OTTO
IPC: B65H49/38
Filed: 1989-11-08
Abstract: In a spinning mill, and running between the different sections of the plant, are storage trolleys, with loading and unloading facilities. The trolley (5) with base (8) has four wheels, which may swivel to run in any direction, or to be on a track. The stand (9) is central, and slides onto two upright bars from the base. In a check pattern with suitable distance for cops without touching each other, are numerous spigots (10) suitable for a cop or tube (4). There is a top hook attachment (12), so that the stand may be lifted off the trolley, complete with a load of cops on each side. The troughs (25) on the endless conveyor (20) are employed to load or unload the cops, and which may be carried in our out of the machines by other conveyors, with systems to transfer from laid down to upright position. To enable this to be done automatically, the troughs are angled down, and the spigots up. Also the spigot are hex shaped to touch tube interior only where necessary. The base of the spigot is enlarged and welded to the stand to avoid the ends of yarn engaging in crevices. On the endless belt (20) ejectors are provided, which slide in a slot beneath the spigot, which enables the cop or tube to be lifted from the stand (9), and transferred to  the trough (25) on the conveyor. USE - Automatic transfer of full cops from spinning frames to steam treatment equipment, to cone winders, etc., with return of empty tubes, avoiding damage by handling or condensation, packing, etc.

Title: Prodn. of sweets or candies, esp. fruit gums - by casting sweetmeat mixt. into two half-shapes of thin, shape-stable film, and joining the two halves
Inventor: MEDERER HERBERT
IPC: A23G3/20
Filed: 1990-02-15
Abstract: Casting process for forming sweetmeats esp. fruit gum bonbons comprises (1) preparing two half-forms from thin, shape-stable films, (b) pouring sweetmeat mixt. into at least one of the half forms; and (c) closing the two half-forms to make the sweetmeat. Pref. the sweetmeat mixt. is poured into both half-forms, and allowed to reach a certain degree of hardness before the two halves are joined: or the mixt. is poured into one half, the other half is closed over the top and the two halves are moved so that the sweetmeat mixt. coats the whole of the inner surface before the mixt. is cooled. Both shape-stable films are locked together by turning along the same axis. The half-forms remain as a coating on the outside of the sweetmeat product, or the sweetmeat is punched out from the coating. Single bonbons or several bonbons can be punched out. The bonbons can be removed by hand from the coating at a pre-determined place. The half-forms can be joined in sections or at points, by heating. USE/ADVANTAGE - Previously, fruit gum bonbons have been formed by pouring the mixt. into recesses in a very large volume of compressed maize starch powder. The process required large quantities of the starch powder and only two-dimensionally shaped bonbons could be formed easily.

Title: GTO thyristor operating method - having additional supply to gate to cause breakdown after closed period
Inventor: BORNHARDT KLAUS DIPL ING
IPC: H03K17/732
Filed: 1990-04-23
Abstract: Upon return of the anode-cathode voltage at the end of the closed period, an additional negative voltage is applied to the gate of the GTO so as to bring its gate-cathode path into the breakdown state. The additional voltage is derived for the switch-off  discharge of the GTO, and is limited to a predetermined voltage. Where the gate is coupled to a quench circuit via a switch, it is also coupled to an additional negative de source (C1) via an additional switch, e.g. a FET (S2). This may be controlled  from the switch-off discharge. ADVANTAGE - Reduced switch off dissipation.
