Patent DE-4122997-A1 (DE)
Title: Self-centring trepanning tool with blank ejector - has centring drill with automatic clutch and spring-loaded ejector plunger
Inventor: KISHIDA SHIGERU
IPC: B23B51/04
Filed: 1991-07-11
Abstract: The tool is particularly suitable for use in a portable power tool. It has a hollow body (1) with a shank (2) at one end and a nose (3) at the other end for a trepanning tool (20). Guided in the body is a centring drill (4) with a locating collar (6) and serrated driving disk (5) at the top end. A sleeve (15) can slide a limited amount on the drill and is urged outwards by spring (16). The drill is pushed outwards by spring (7) and is retained by a grub screw (9) entering a serration (8) in the driving disk (5). As the tool is lowered onto the work and rotated, the tip (4a) drills a shallow pilot hole. When the bottom end of the sleeve (15) touches the work, the sleeve moves upwards and pushes the spring tensioned latch (10) outwards. This releases locating collar (6), allowing the drill to move upwards and disengaging the drive disk (5) from grub screw (9). The drill now acts as a non-rotating pilot whilst the cutter trepans the workpiece. Finally the sleeve pushes the blank out of the trepanning cutter under pressure of the compressed spring (7). USE/ADVANTAGE - Accurate centring. Simple and convenient to use.
Patent DE-4123578-A1 (DE)
Title: Non-invasive determination of local heart potentials - measuring potential difference between neighbouring electrodes on surface of thorax and summing absolute contributions to form local potential
Inventor: ROMBERG DIETRICH DIPL ING
IPC: A61B5/308
Filed: 1991-07-13
Abstract: Potentials supplied from electrodes (1) on the surface of the thorax are amplified and fed via electronic switches (3,4) to a differential amplifier (5). The differential amplifier forms the difference between neighbouring electrodes. The absolute contributions of these potential differences are summated for each electrode in a computer (7), to form a local potential. Noise voltages and non-local heart potentials act as common-mode signals, and are suppressed by the difference calculation. ADVANTAGE - Reduced risk to patient.

Title: Formation of shapes in textile material - has an automatic process which is switched off for a reversed curve formation
Inventor: BIEGGER ROLAND
IPC: D06H7/22
Filed: 1992-04-16
Abstract: A process to control a cutter, to form curves in textile fabric along a repeating pattern at one side of the fabric. The cutter head has a drive mechanism to form the shapes as the fabric progresses, and there are optoelectric sensors in the head to correct the shape of the pattern being followed. Prior to machining, the pattern is separated into sections which can be cnotrolled automatically, and those which cannot, so that at the end of a defined step, the process is stopped, as the fabric is reversed to complete the required shape. The repeating pattern (M) is pref. cut alon gthe edge of a curtain (TB0. The material is moving along the cutting tabel in direction (LR), with the coordinate (Y). The shapes (MS1, MS3, MS5) can be shaped automatically as the fabric grogresses, by a cutter head having a heating element or laser, and which is controlled by optoelectric sensors and light projection, coupled to a step motor, which moves the cutter head in the appropriate direction. The shapes (MS2, MS4) have the cut away setion (LS) in a reverse direction to the flow direction (LR), especially as stage III, which is also along the coordinate (X). This means that is is necessary to stop the automatic progress during this part of the process. A counter is required to determine the exact position at which the automatic action is switched off, and then on again. ADVANTAGE - The process enables curves to be cut along the edge of curtain material, which are in the opposite direction to the flow of material along the cutting table.
Patent DE-4215004-A1 (DE)
Title: Drafting system for sliver to yarn spinning machines - comprises aprons guided by cage swinging around lower roller axis on stop and holding upper rollers and aprons parallel to lower rollers

Abstract: The system has upper (16) and lower (17) aprons guided by a cage (20) which swings about the axis (A) of the lower drafting roller against an adjustable stop (23). The cage (20) ensures that the upper drafting roller pair and the upper apron (16) are parallel to the lower roller (8). A common stop (23) may be used for cages (20). The direction (W) of the loading force (P) on the upper apron (16) may pass at least ca. through the stop (23). The lower drafting rollers (1,2,3) are pref. part of continuous shafts (7,8,9) running the length of the machine. The upper pressure rollers (4,5,6) are in separate pairs. A cage (20) with guide bars (18,19) swings round the axis (A) of the lower roller (8) and ensures the aprons (16,17) run parallel. It abuts against a stop (23) which is mounted on an eccentric bearing for easy common height adjustment along the length of the machine. When the drafting system is opened, the upper apron (16) is pref not swung upwards so tolerances are maintained from position to position. USE/ADVANTAGE - The system is partic. useful for sliver to yarn spinning with drafts up to 150.
