Patent DE-3173303-D1 (DE)
Title: Method of and apparatus for converting an analogue voltage to a digital representation
Inventor: FIELDEN JOHN SPENSLEY
IPC: H03M1/12
Filed: 1981-08-14
Granted: 1986-02-06
Abstract: An analogue voltage-to-digital converter has a voltage divider (11) with a plurality of steps (13) for comparison with the unknown voltage and in addition provides interpolation between steps to improve the accuracy. Interpolation is effected by adding a ramp voltage from a generator (22) to the unknown, the ramp voltage ramping through a magnitude equivalent to at least one step. With one tap (13) on the voltage divider (11) selected, comparison of the unknown plus ramp voltage is effected in a comparator (14) successively as the voltage ramps. By noting when the combined voltage reaches the level of one of the reference voltages and by counting in a microprocessor (16) the number of comparisons made from the time when the ramp voltage is at a predetermined magnitude and comparing this with the time taken to ramp through one or a plurality of whole steps, determination can be made of the magnitude of the unknown voltage to a fraction of a step.

Title: Power capacitor structure and method of assembly
Inventor: MERCIER GEORGE EDWARD
IPC: H01G4/38
Filed: 1981-10-30
Granted: 1986-03-20
Abstract: A power capacitor and method of making it employs the technique of stacking capacitor sections together in an enclosure of which each section includes rolled electrode foils and dielectric layers of which at least one of the electrodes has a rolled edge resulting in a greater thickness in that portion of the section. In order to permit thorough impregnation of the section, the winding tension is deliberately made loose and the initially resulting section is insufficiently tight to retain conductive tabs reliably in contact with the foil electrodes. The stacked sections have, however, between them in the body portion intermediate the rolled edges, one or more sheets of material that compress the body portion and insure reliable pressure contact thereat while not interfering with the impregnation of the fluid throughout the section.

Title: Oil seal assembly
Inventor: DRUCKTENHENGST ROLF
IPC: F16J15/3256
Filed: 1982-08-03
Granted: 1985-04-25
Abstract: A cassette seal comprising an inner ring and an outer ring has angle or L-shaped profiles which are arranged together inside each other to form a substantially rectangularly bounded hollow space. The inner ring has a rubber coating (6) for support and sealing on an axle or shaft. The leg of one ring which extends in the radial direction and is facing away from the sealed-off medium has a sealing lip formed from an elastomer material which extends into the hollow space and rests against the leg of the other ring extending in the axial direction. The sealing lip is followed by at least one dust lip spaced at an axial distance away from the sealed-off medium. The leg of the other ring which is facing the sealed-off medium and which extends in the radial direction is sealed against the leg of the one ring extending in the axial direction by a labyrinth gap (12). The contact surface assigned to the dust lip changes into the contact surface assigned to the sealing lip without enlargement of the diameter.

Title: Method and apparatus for forming a strap loop about an article
Inventor: ANNIS JAMES R
IPC: B65B13/02
Filed: 1982-02-03
Granted: 1986-07-10
Abstract: A method and apparatus are provided for forming a strap loop and securing it about an article (P). The strap free end is pressed against a guide surface (224) and moved in a path to form a primary strap loop (LP) while permitting the primary strap loop (LP) to twist off of the guide surface (224). With the free end of the strap (S) held against further movement, the trailing portion of the strap (S) is fed to expand the loop to a predetermined larger size. The article (P) is inserted in the loop (LF) and the trailing portion of the strap (S) is withdrawn to tighten the loop (LF) about the package (P). The trailing portion of the strap (S) is severed from the tightened strap loop (LF) and the overlapping portions of the strap (S) are then sealed by a friction-fusion weld.

Title: Reinforcement-iron holder for use in joining cast concrete work and method of manufacturing the same
Inventor: BRECHBUHLER FRITZ
IPC: E04C5/16
Filed: 1982-09-10
Granted: 1986-10-09
Abstract: The reinforcing rod holder includes a hollow body (1) having a depression in which the downwardly bent reinforcing rods (2) are inserted in such a manner that their U-shaped anchoring portions protrude. The free end (3 and 4) of the reinforcing rods are disposed entirely in the hollow body, together with the bend portion. To permit insertion of the anchoring portions, the hollow body is provided with apertures (5), and holes (6) having a diameter which is approximately identical to the diameter of the reinforcing rods are provided at the two ends of such apertures (5), while the central portion of the apertures is sealed by two overlapping flaps (7). The hollow body is further provided with mounting or support ribs (8) at the apertures (5) and two spacer ribs (9 and 10) between the last three apertures (5) in order to serve as support faces for the ends of the reinforcing rods. The hollow body, containing the reinforcing rods, is filled with expanded plastic material. A reinforcing rod holder of this type is used in connection-type concreting operations and is advantageous in that, on the one hand, the portions of the reinforcing rods not embedded in concrete are packed in expanded plastics material and therefore cannot rust and, on the other hand, the expanded plastics material can be completely and conveniently removed by extracting the hollow body when the connection-type concreting operation is being carried out. In addition, the hollow body actually serves as a mould, thereby ensuring that the reinforcing rod holder is produced rationally and cheaply.
