Patent DE-2042105-A1 (DE)
Title: Optical circuit assembly - using fibre optics components
Inventor: PAGE BURR ROBERT
IPC: G02B6/13
Filed: 1970-08-18
Abstract: Optical circuits, analogous to microwave waveguide assemblies, are manufactured by drawing optical conductor material, e.g. fibre optics light guide from a storage system via a travelling guide whose path over the surface of a carrier plate corresponds to the desired circuit or element pattern. As each element is placed tightly against and fixed to the carrier it is cut to the desired length. Joints between adjacent or crossing sections are made by punching or drilling holes which are then filled with optically conductive material.

Title: Pressure governor for continuous flow electric water heater - has non return bypass valve between inlet and outlet
IPC: F24H9/20
Filed: 1974-02-28
Abstract: The governor is a plastic block with recesses in its upper and lower faces joined by a passage. A diaphragm is clamped in the upper recess by a cover plate and carries a stem through the passage with a valve plate moving within the lower recess and seating on the bottom of the passage. Water flows through an inlet passage, through the valve, under the diaphragm and out by a passage. A bypass passage links the inlet and outlet passages directly and contains a non-return valve normally closed by a spring. If pressure builds up in the heater because of failure of the operating thermostat the non-return valve opens and relieves the pressure by permitting back-flow into the inlet.

Title: Nuclear power plant with condensation sump for leaked steam - has two communicating sumps both within primary circuit containment
Inventor: JOST NORBERT ING GRAD
IPC: G21C9/012
Filed: 1974-11-05
Abstract: A pressure blowdown system for a nuclear power plant comprises wate sumps in two chambers interconnected below the water surface; a leak in the primary coolant circuit causes a pressure build-up in one chamber (pressure chamber) and a resultant flow of water through the communicating passages into the second chamber (condensation chamber). Both these chambers contain primary coolant equipment so that when a leak occurs in one chamber, that chamber becomes the pressure chamber and the other becomes the condensation chamber. Emergency generating plant is pref. housed in a further chamber immediately adjacent to the first two, so that the cooling water for this emergency plant can be supplied from the permanent water sump in the two chamber. Pref. the two chambers are arranged concentrically one outside the other. Instead of having the entire primary coolant circuit contained inside a pressure chamber, with communicating passages to a further condensation chamber, both chambers are utilised for housing the primary coolant plant items; therefore the total volume of these two chambers is considerably reduced, leading to a more compact plant layout.

Title: Shuttleless loom for producing pile tapes uses flexible reed bar - which deforms during beating up and forms one warp into loop pile
Inventor: DIESNER FERDINAND
IPC: D03D39/00
Filed: 1974-12-11
Abstract: A loom for producing tapes with a loop pile on one surface use three warp layers, two of the warp layers forming a first shed in which a weft yarn is inserted to form a base weave and one of these warp layers forming with the third warp layer a second shed in which a second weft yarn is inserted. This weft yarn is beaten up with a reed bar which is flexible and which as it is moved to beat up deforms in a region which is not located in the second shed. The action of the bar on the warp yarns of the third warp layer forms these yarns into loops which project from the upper surface of the woven tape. After beating up the reed bar reverts to a straight bar. The beating up mechanism is simpler and allows weaving at higher speeds than previous beating up mechanisms.

Title: Punched data card with bonded magnetic film over part section - provides a facility for changing the stored data content
IPC: G06K19/02
Filed: 1974-12-18
Abstract: The concept of a punched data card for information storage is modified to allow information to be cancelled i.e. the card is no longer a read-only device it becomes a read and write unit. A specific data region of the card (1) is assigned for information that may require modification (A). Magnetic film (2) is bonded to the card and to ensure that the composite card is of constant thickness the film is inset into the surface. It is suggested that the card would be advantageous for letter information storage.
