Title: Recirculating liquids in closed circuit - during liquid chromatography to provide short working columns
Inventor: MINARIK MILAN DIPL ING
IPC: G01N30/20
Filed: 1977-07-13
Abstract: Method for recirculating a liq. media in a closed circuit esp. for the liquid chromatography cycle in which the circulating liquid at its entry into the circuit is thrust into movement by a working medium under pressure from a pump, a gas bottle etc. is claimed. The liquid leaving the circuit in the form of columns is mechanically transported back to the entry point of the circuit at regular intervals, and the copolymers of liquid are reinjected into the circuit with the aid of the working medium. The process is effected in such a manner that the outward expression of liqins at the outlet and the inward injection of the liquid at the entry, are simultaneous. The appts. provides improved efficiency of washing of the chromatography zones using a cheaper equipment than in prior art.

Title: Typewriter with type levers operated by flexible bands - deformed into recesses in fixed plate on depression of respective keys
Inventor: DROGI DIETER
IPC: B41J7/10
Filed: 1977-08-13
Abstract: Typewriter has type levers(1) each connected to flexible band(3), the band passes from the lever over a fixed plate and on to a location(26) where the band is secured to the machine frame. The associated key(50) of the keyboard is situated above the part of the band overlying the plate. When the key is depressed, it deforms the band into a recess(29) in the plate thereby tensioning the band and operating the type lever. The amount of deformation of the bands is adjustable collectively(12) by raising or lowering the plate which embodies all the respective recesses.

Title: Sliding vane type pump or motor - has rotor and casing turning together, with vane attached to inside of casing
Inventor: THEISEN ALOIS
IPC: F01C11/00
Filed: 1977-08-30
Abstract: The machine has a cylindrical rotor (6) mounted eccentrically within a cylindrical casing (4).

Title: Take=up motion for face to face carpet looms - has strippers lifting fabric from draw roller needles
Inventor: HARTMANN WERNER
IPC: D03D49/20
Filed: 1977-09-12
Abstract: A take-off mechanism for a loom, partic. a carpet loom weaving a double fabric which is slit horizontally forming two pieces, is fitted with needle cylinders for drawing the fabric out of the weaving zone. Each cylinder has a guide roller and the piece is led away between the roller and the cylinder to the winding reel. Each draw cylinder has a support ring which can be displaced circumferentially by an adjusting mechanism attached to the frame, and carries a support rail parallel to each draw cylinder to which projecting details are assembled for stripping the fabric from the needles. Pref. two support rings are provided for each cylinder to support the rail carrying the strippers and the rings fit on the cylinder journals. The support rings are adjusted by screws linked flexibly to the rings, the long axes of the upper and lower rings being aligned to each other. The stripped details consists of forks with wedge section tines inserted between the needles of the cylinder, and 1 stripper is allocated to each cylinder. Each adjusting screw may have a limit switch for stopping the machine and there may be an intermittenly working element such as a cam, acting on the screws to rock the stripper rail. The goods are released easily from the needle cylinder without any tension being exerted by the reel. the fabric cannot be retained by the needles and damaged. The simpler design makes it unnecessary to stop the machine for long whilst the reels of carpet are removed.

Title: Wire winding spool support - has pair of frame members provided with axially movable cones for driving spool on mandrel
Inventor: HOORELBEKE LUC
IPC: B65H54/54
Filed: 1978-02-24
Abstract: The wire winding spool support has a pair of frame members in which is mounted co-axially a pair of centres, one of which is driven and both are arranged for releasable attached to the ends of a hollow shaft for spool chaning. The support permits dynamically balanced and vibration free mounting of spools which are quickly releasable. The hollow shaft is a radially distensible mandrel for drivable supporting of the spool. THe distension is effected by axial displacement of a shaft provided with spring washers and conical elements which act on radially distensible elements. Opposite axial movement of the shaft results in radial collapsing of the mandrel for spool release.

Title: Digital coder for angular position of shaft - employs vernier principle and has photoelectric devices to provide accurate measurement
Inventor: WERNICKE JOACHIM DR ING
IPC: G06F11/08
Filed: 1978-03-16
Abstract: The shaft encoder contains a disc (1) fixed to a shaft (2) running in bearings (3).

Title: Gas-tight screw closure cap for bottles - is tightened by axial deformation of cap end and thread flanks
IPC: B67B3/20
Filed: 1978-07-06
Abstract: The bottle closure which forms a gas tight seal on the bottle top, is of metal and it has a preformed screw thread. The closing cap is tightened on the bottle by the pressure of the closing ram alone. The closing cap (1) is in the first stage attached by rotating the screw. In the second stage the closing ram ensures gas tight pressing of the seal (9) and the ram bulges the bottom (2) and the screw thread (4) of the cap so far inwards that the shortening of the axial length of the top transition region (5) of the screw thread (4) ensures that the screw thread flanks are pulled tight against the bottle neck screw thread. Wedging of the screw thread ensures the final cap removing torque.
