Patent DE-2515025-A1 (DE)
Title: Multicore electrical lead with transversely grooved casing - providing rigidity for laying on walls and ceilings with fewer staples
Inventor: JORDAN ALFRED
IPC: H01B7/18
Filed: 1975-04-07
Abstract: Multi-core electrical lead comprises a polyethylene casing with transverse grooves surrounding the insulated cores, the space between the core insulation and the transversely grooved casing being filled with insulating material. Pref. the grooved casing has an outer sheath of PVC which is smooth and glossy on the outside. Pref. the insulating filling material comprises a rubber- and chalk-containing mixture which is plastic and water-repellent and is sprayed onto the cores, after which the casing is sprayed on in the same stage in the smooth state. The grooves, which extend helically, are then formed in the casing by a multi-roller device, compressing the insulating material to eliminate any cavities in the material.

Title: System for line finding and adjusting in reading appts. - has automatic parallel adjustment between lines and window
Inventor: UHLIG WERNER
IPC: G06V30/146
Filed: 1975-04-14
Abstract: Coherent optical reading of lines with series of symbols and reflecting and/or transparent symbols carrier provided with adjustment and reading beam bundles. The purpose is to reduce the complexity of the optical-electronic equipment of reading and adjusting. A subsequent automatic adjustment is carried out during the actual reading by mostly optical means. The lines to be read and the reading window are maintained in parallel. The symbols carrier is adjusted in parallel to the reading window during the reading by collimated adjusting beam bundles working independently of the reading beam bundles. The adjusting beam bundles are directed to the reading window in front of the carrier at a vertical angle.

Title: Restoration of underground pipes esp. concrete water or effluent pipes - preventing further attack by aggressive vapours by using prefabricated plastic coated concrete elements
IPC: F16L55/165
Filed: 1975-06-03
Abstract: In the restoration of pipes laid in the ground, particularly concrete water and effluent pipes by lining past parts of the interior surface with plastic, a plastic film is bonded to this surface and is anchored in concrete by means of anchoring elements moulded on its external surface. The whole interior surface- or, where desired, that part most likely to be attacked by vapours or gases produced from or evolved by the effluent- of the concrete pipe can be covered with plastic which will not be dislodged by the hydrostatic head of ground water acting on the outside of the pipe. This permits reconditioning of the pipes for continued service. Pref. prefabricated sections are used, the inner face of which is covered by a plastic film, suitably a vinyl polymer, esp. p.v.c. which has a series of anchoring elements on its rear face. These may be mutually spaced, parallel T-shaped profiles running parallel to the pipe axis.
Patent DE-2542529-A1 (DE)
Title: Permanent formwork for reinforced concrete ceiling - is retained when concrete sets, and profiled for high load bearing capacity
Inventor: KLEMM WOLF
IPC: E04B5/40
Filed: 1975-09-24
Abstract: Lost formwork for reinforced concrete floor-ceiling construction preferably, has a high intrinsic load-carrying capacity in cross-section, by virtue of corrugated, ribbed, prismatic, beam, stem, tubular and/or box-type members and/or reinforcements. This enables it to span the required open spaces, with or without supports, and to absord the forces and loads involved in concreting. Steel reinforcement may be incorporated before or after laying, between or within the profiled sections. The visible underside may be profiled or flat. A moisture-resistant layer may be added before concreting. Work and costs are reduced, and building operations can proceed without waiting for the concrete to set.

Title: Equitable tonal range orchestral horn - has alternative long or short air passageways of equivalent tonal quality and automatic drainage of condensation
Inventor: VENEKLASEN MARK S
IPC: G10D9/04
Filed: 1975-10-20
Abstract: The orchestral horn has a short pipe or sleeve and long pipe or arc which may be alternatively incorporated into the effective air path. The short acoustic path formed by the short pipe or sleeve has more additional involutions than the acoustic path formed by incorporation of the long pipe or arc. The sound quality of both these air paths is of comparable mature and quality. The number of involutions in the short and long acoustic paths is proportional to the inverse ratio of their lengths. Condensation automatically leaks out in one playing position to prevent cracking of notes.

Title: Tomographic appts. superposing scanning signals of individual pictures - reads scan signals out of storage simultaneously and passes each signal set through adjustable delay to superposer
Inventor: MEYER-EBRECHT DIETRICH DR
IPC: A61B6/02
Filed: 1975-12-06
Abstract: The photographic apparatus superposes staggered photographs of the object taken from different perspectives. Individual photographs are scanned and stored as scanning signals.

Title: Electrical control circuit for toy racing cars - uses pulses of different duration superimposed on DC supply to control several cars simultaneously
Inventor: KRALICEK JAN
IPC: A63H30/02
Filed: 1976-09-17
Abstract: A system of electric impulses imposed on a d.c. supply is used to control several toy racing cars simultaneously. The model cars run on an insulated board and receive current through conducting rails in the board surface. The control system emits a synchronising pulse of 2V at 1 milli-second intervals. The system also emits a series of pulses of variable amplitude and of 0.01 milli-second duration. The interval between these pulses increases from a minimum to a maximum value during each period between the 2V pulses. The toy cars have receivers which distinguish between the pulses of different intervals so that each car can be operated independently of the others.

Title: Fluid flow measuring instrument - has floating body displaced against restoring force in direction of its height and tapered in opposite direction of flow
Inventor: LUTZ KURT DIPL PHYS
IPC: G01F1/22
Filed: 1976-10-15
Abstract: A float measuring instrument has a floating body displaced against restoring force in direction of its height and tapered in opposite direction of flow. The actual curve for the first form (10) of the floating body indicates the measure of value of the flow as a function of the height of the body. (10). It is empirically ascertained. The original shape (10) for the floating body is changed along its height such that an altered floating body (12) is formed for which a measured value (D12) of the flow is assigned to each height (h1). The measured value (D12) of the flow lies on a given nominal curve.

Title: Radio communications system with fixed and mobile stations - uses different bit sequences for synchronisation blocks from master and mobile stations
Inventor: KUEHL WERNER
IPC: H04L1/00
