Title: Winding station for conical cross-wound spools - ensures uniform winding at higher speeds, without excess at package ends
Inventor: KAMP HEINZ
IPC: B65H54/10
Filed: 1976-06-12
Abstract: A winder for conical cross wound packages with constant thread delivery speed has the spool driven by a contacting roller the surface of which is cambered. The conical package tilts with its holder on an axis at right angles to the axis of rotation of the cone, under the control of a pivoting mechanism. This synchronises the point at which the thread runs on to the package with the point of contact between the package and the driving roller. The driving roller is formed by a grooved drum for guiding the thread and a yarn guide traversing synchronously with the roller groove is provided to deliver the thread into the guide groove of the roller. The auxiliary thread guide is traversed by means of an eccentric, a wobble plate or a control cam, and the shaft for tilting the spool and that driving the thread guide are synchronised. Provides a simple means of overcoming the need to slow down and accelerate the mass of the guides at the ends of the stroke. The winding of the cone is uniform and entirely without the extra amts. laid on at the reversal points of the traverse. The thread is prevented from jumping out the groove and winding speeds can be increased.

Title: Filter type automatic coffee machine - has water dispenser with magnetic piston which acts on magnetically controlled switches to control amount of water dispensed (NL13.4.77)
Inventor: SIDLER RENE
IPC: A47J31/40
Filed: 1976-08-20
Abstract: The automatic coffee machine contains a pump (MP) which pumps water via multi-directional valves (DV1, DV2) in a ring circuit (1.2.3.4) containing a measuring cylinder(5) to a water heater (EH) which heats the water to be passed on into the coffee filter. The measuring cylinder has a number of magnetic switches (S1, S2, S3) connected to the multi-directional valves (DV1, DV2). These switches are operated by a permanent magnet (9) in the piston (6) of the measuring cylinder so that the measured quantity can be changed to suit the size of container to be filled. Water passes from the pump through the first valve (DV1) into the first part (1) of the ring circuit and into the measuring cylinder (5). This pressure pushes the piston (6) up the cylinder until half the required amount of water in the top part of the cylinder has been forced out via the outlet tube (3) and outlet valve (DV2) to the heater (EH). At this point a magnetic switch (S1, S2, or S3) alters the direction of the valves (DV1, DV2) so that water is passed through the second inlet tube (2) to the measuring cylinder to return the piston (6) to the cylinder base and force out the remaining water quantity to the heater (EH). At this point a further magnetic switch (S0) cuts out the pump.

Title: Hydraulically driven pile extractor - has cylindrical impact element with bore for cyclically loaded rod collar
Inventor: GULCZYNSKI FRANZ
IPC: B25D9/14
Filed: 1976-09-15
Abstract: The hydraulically driven pile extractor is connected to a lifting crane. The pile extractor has a cylindrical vertically reciprocating impact element. The central bore of this element carries a rod connected to the pile. Upwards directed impacts are exerted on this rod on extraction when the crane exerts pull. The extractor has a minimum of components and the hydraulic control system connects components to form a unit. The working life of this arrangement is greatly extended. The tension rod (1) projects to both ends of the impact element (4). The collar (11) of the rod moves in the bore of the impact element (4). This collar divides the chamber into two chambers with variable volume. The upwards lift influencing control chamber (12a) is cyclically loaded with compressed liquid. A constant pressure is maintained in the other control chamber (12b).
