IPC: A01D87/12
Filed: 1975-09-26
Abstract: The machine for picking up and unloading bales of hay or straw consists of a support-arm (1) which is perpendicular to the direction of travel. One end of the arm (1) has a pair of mounting bars (2, 3) by which the arm (1) is joined to the lower links (4, 5) of a tractor (6). A support-frame (7) on the arm (1) is joined to the tractor's upper linkage (8) and carries a coupling (9). Bevelled gears (10) fixed on the arm (1), are connected between the drive shaft (11) from the tractor power take-off, and the drive shaft (13) for the bale pick-up and unloading mechanism. The end of the support-arm (1) not facing the tractor has a plate (14) supporting a pivoted frame (15) with two continuous separate conveyor-belts (16, 17). The belts (16, 17) are driven over guide-rollers (21, 22). A lever (24), grasped from the driver's seat, adjusts the distance between the two conveyor-belts (16, 17). A hand-crank (25) allows pivoting of the frame (15).

Title: Ring or box spanner for bolts - has locating facility by initial movement of spanner ring and bolt retaining rim
Inventor: BAHRTON PER GOERAN
IPC: B25B13/04
Filed: 1976-01-30
Abstract: The spanner is for nuts, bolts or screws with a multi sided head. The spanner internal dimension is slightly larger than the bolt and has twice as many corners as the bolt or nut being turned. An initial rotary movement of the spanner (10) is allowed without moving the bolt. This initial movement either moves the spanner axially relative to the bolt or angles the spanner relative to the bolt axis. There is a rim (11b) round the top of the open ring to prevent the bolt head protruding through. The corners have half the depth of the spanner head and for the angled spanner there is a conical shaping on the edge of the ring near the spanner handle.

Title: Thermal self-oxidn. of aliphatic prim. amido alcohol - to amino carboxylic acid, opt. with subsequent polyamide formation
Inventor: BEHNCKE HERMANN DR
IPC: C08G69/16
Filed: 1976-09-29
Abstract: Self-oxidation occurs at 200-220 degrees C, with hydrogen evolution, under the action of the amino gps. as basic reaction promoters. The amino gps. are pref. positioned at the end of the aliphatic chains. If the reaction mixt. is cooled immediately after the cessation of the hydrogen evolution, the reaction prod. is the corresp. amino carboxylic acid. If, however, the heating is continued, a corresp. polyamide is formed. Polyamides can be produced from aliphatic, primary omega-amino alcohols in one continuous operation. The evolved hydrogen can be utilised, e.g. for de-scaling iron constructions, which can be subsequently provided with a protection polyamide coating.

Title: Ultrafiltration system for blood - using membranes over filter chambers of compact dimensions to ensure uniform pressure
Inventor: FRANKEN WALTER DIPL CHEM DR
IPC: B01D65/08
Filed: 1976-11-26
Abstract: Ultrafiltration system uses a number of filter chambers having a narrow slot, covered on >=1 side by a filter membrane. There is a run off for the filtered liquor and for the concentrate. The height of each slot shaped chamber is between 8-150 mu m. The width and length are so proportioned that the pressure in the liquor being filtered is essentially uniform across the chamber. There is thus significant resistance to flow across it. The depth should be in the range 5-150 mm. Alternatively the width can be increased as the chamber extends away from the feed point to compensate for the increasing viscosity of the liq. as it becomes concentrated. Elastic cushions can be used to support the membrane. For use in the ultrafiltration of blood where it is important to avoid damage to the blood cells. Existing ultrafilters have the problem of elongated filter chambers which can have significant pressure dorps down then causing damage to the blood being filtered. The filter described overcomes this problem.
