Title: High speed ball retainer for cold former dies - has intermediate workpiece gripping device reducing die erosion rate
Inventor: HAINES ALLAN DAVIS
IPC: B21J5/00
Filed: 1978-06-14
Abstract: A cold former comprises a frame, a pair of dies mounted on the frame for relative movement between a retracted position spaced from each other to allow positioning of a workpiece between the dies and a closed forward position to deform the workpiece to a required shape. Power drive moves the dies from the retracted position to an intermediate gripping position, so that workpiece is initially gripped while the dies are moving relative to each other with a first relative velocity. The dies then move from gripping position to closed position with an initial second relative velocity which is >= the first relative velocity. The first relative velocity is sufficiently lower than the second velocity to reduce the rate of erosion of the dies.
Patent DE-2831081-A1 (DE)
Title: Loop-free edges for flat-bed knitted articles - produced by momentary application of yarn tension
Inventor: STEIGER GERARD
IPC: D04B1/22
Filed: 1978-07-14
Abstract: A process for preventing the formation of loose loops of yarn along the sides of articles knitted on a flat-bed machine involves imposing a tension on the yarn as it is fed to the last needle or needles. The tension is produced by a clamping mechanism to arrest the thread feed which is automatically activated as the carriage approaches the end of its traverse, and released when the carriage has passed the same needles on the return movement. A straight, clean knitted edge is produced, which is partic. desirable for elastic articles such as orthopaedic stockings.

Patent DE-2838676-A1 (DE)
Inventor: JAKOPIC ERICH DR
IPC: H01J37/305
Filed: 1978-09-05
Abstract: The gas discharge chamber (1) of the source of atomic beams or molecular beams serves to receive at least one target (2) and is connected via an extraction port (4) in a partition (5) to a substrate space (6) in which there is a substrate (3). The extraction port (4) is dimensioned and arranged in such a way that atomic beams and/or molecular beams originating from the target (2) enter from the chamber (1) into the substrate space (6). At the same time, transgression of the discharge from the chamber (1) into the substrate space (6) is suppressed thereby and a pressure difference between the chamber (1) and the substrate space (6) is maintained. The latter makes it possible to combine the advantages of cathodic sputtering with those of ion impact sputtering. The source can be produced inexpensively with small dimensions, is easy and reliable in handling and, above all, has a considerably enhanced productive capacity. The latter applies in particular with additional use of HF, a thermionic cathode, a deflection device for the removal of charged particles, a cooling device, and electric and/or magnetic fields. <IMAGE>

Title: Resistance tester with variable frequency acoustic indication - has resistor in series with protective diode across multivibrator for voltage magnitude indication
Inventor: HEINICKEL KURT
IPC: G01R27/08
Filed: 1978-10-02

Filed: 1978-10-18
Abstract: The timing disc (1) has guides allowing the switch riders (3) to be moved into positions around the disc (1) corresp. to the required switching programme, the switch riders (3) being permanently attached to the disc (1). The cooperating guide surfaces (8) between the disc (1) and the switch riders (3) incorporate axially effective locking teeth (10, 11) preventing removal of the switch riders once they have been fitted to the disc. Pref. each of the switch riders (3) has a U-shaped cross-section, so that it fits over an annular upstanding shoulder (2) around the periphery of the disc (1). The arms (6, 7) of the U enclose a U shaped guide element (8) in contact with the guide surfaces of the annular shoulder (2). Each arm of the guide element has an inwardly projecting locking tooth (10, 11) at its end. These allow the switch rider (3) to be lifted away from the top of the shoulder (2) when the position of the switch rider (3) is being adjusted, but lock into respective notches in the sides of the shoulder, to prevent the full removal of the switch rider (3). The disc (1) and the switch riders (3) can both be made from injection moulded plastics.

Title: Equipment measuring surface texture - uses monochromatic radiation to study surface layer of non-amorphous polycrystalline body
Inventor: BORN EBERHARD
IPC: G01N23/207
Filed: 1979-03-17
Abstract: Monochromatic radiation from an X-ray source is brought to a focus and the continuing, weakly divergent beam is aimed at the surface of the body. The reflected radiation is viewed through a slit or hole positioned at the desired angle. Measurements at different angles build up a description of the surface layer texture. The viewing slit may be parallel or vertical to the plane of the incident beam. Other forms of radiation such as neutron or electron beams may also be used.

Inventor: SCHOENHUBER MAX-JOSEF DR ING
IPC: G01N1/10
Filed: 1979-04-06
Abstract: A sample filling device for milk collection trucks is proposed, in which there is a number of sample containers (2) in a sample container carrier (1) or sample container stand, which sample containers have on their mouths an elastic container closure (3) which is pierced by an injection device (4) for filling the sample containers. When the injection device (4) has been withdrawn, the elastic container closure (3) closes automatically. The closing and reopening of the sample containers (2) can thus be carried out in an easier and more rapid manner without the safety of the closure of the sample relative to environmental influences being at risk, the container closure being provided jointly for the sample containers (2) in the form of an elastically resilient, rubber-type layer (3) which is pressed by means of a pressing-on device (5, 6, 7) against the mouths of the sample containers (2) lying in one plane and which can be pierced by the injection device (4). <IMAGE>

Title: Equipment extracting gold from siliceous deposits - uses turbulence produced by underwater jet to separate enriched fraction
Inventor: BRAEUER MANFRED
IPC: B03B11/00
Filed: 1979-06-15
Abstract: The separator consists of an open tank (14) with an inclined side wall (18) and an inclined bottom (16) fitted with an outlet connection (70) at the lowest point. The material to be handled is fed periodically from a hopper into the open water level of the tank (14). The tank is fitted with a combined agitator /screw conveyor on a shaft (26) parallel to the inclined bottom. The inclined side wall (18) as well as the inclined bottom have water jets (62,56) which produce a turbulence in the deposit-carrying content of the tank. The effectiveness of the turbulence is increased by the action of the agitator vanes (52). The combined action of the water jets and the agitator blades drives the deposit-carrying water uphill towards areas with decreasing turbulence,where the heavier particles including gold granules tend to sink to the bottom and slip towards the lowest area (54) where they are periodically removed via a pinch cock (74) for further treatment.

Filed: 1979-07-11
Abstract: Pin stenter for the continuous heat-treatment of porous fabric which undergoes shrinkage in two dimensions has an insulated housing within which is at least one impeller for circulating the heating medium, and inserts which direct the medium against the fabric from above and below through arrays of orifices distributed along the length and across the breadth of the fabric. The orifices on one side of the fabric are staggered w.r.t. those on the other side, forming an interlaced chequer board pattern of jets which fling the fabric continuously from top to bottom of the channel in two dimensions. The finished fabric has a pre-determined, uniform width, with a residual shrinkage which approximates to that produced in household tumble dryers.
Patent DE-2930706-A1 (DE)
Inventor: SCHMITZ HERBERT PROF DR MED
IPC: G01N33/58
Filed: 1979-07-28
Abstract: A highly sensitive enzyme immunoassay procedure is disclosed for determining IgM-, IgA-, IgG- and IgE- antibodies which are specific to antigens by coating a solid support with an antibody which selectively binds the antibody to be determined in a serum specimen and reacting the selectively bound antibody with an enzyme labeled microbe or antigen and then determining the enzyme activity of the reaction product as a measure of the antibody to be detected. As the antigen can be effectively labeled a relatively impure antigen can be labeled and used in high dilutions resulting in a very sensitive assay; purification by column chromatography is unnecessary. A kit for conducting the assay is also disclosed.
