Title: Shrink ring commutator with insulated laminations - has insulating strips or pads wound completely round commutator assembly which is subsequently compressed to desired shape
Inventor: FREITAG GERHARD
IPC: H01R43/06
Filed: 1978-11-10
Abstract: The commutator consists of a stack of conductive laminations, held at the inner end by shrink rings and insulated mutually and against the rings. The stack is secured via one shrink ring and an axial coupling ring to the machine coil-former, pref. with an additional insulation. The stack is also insulated on the inside in the direction of the machine shaft. The inside insulation (31) is applied by a process, in which the commutator is completely wound with one or several layers of insulating strip or pads, including the connecting ring (8) and the terminal tags (10). The wrapping of the insulating elements is carried out in an overlapping manner, as with a toroidal coil. The insulation forms a sleeve for adhesive finishing. After the wrapping step the desired contour is obtained in a press tool. After the excessive insulating material has been removed in the region of the terminal tags and the brush contact surface (12) the insulating sleeve is hardened.

Title: Switching equipment for analogue or digital signals - connects by assigning channel on common time multiplexed bus=bar
IPC: H04Q11/04
Filed: 1979-03-12
Abstract: The switching system consists of a number of connection circuits which give access to a bus-bar. The latter has a capacity of 32 time-multiplexed PCM data channels, each at 64kBit/s. Cals are connected by assigning a channel to two connection circuits. Access may be had by analogue or data subscribers using pulse code or delta modulation, including multiplexed inter-connections with other switching units. Connection circuits are grouped according to type of modulation and in each case make the appropriate transformation to and from 64kBit/s PCM data. A connection circuit conducts the necessary exchange of signals with a subscriber. Dialling signals are passed over a data link to the supervisory controller which assigns a bus-bar channel. It also provides clock signals and ensures that only compatible accesses are connected together.

Title: Coupler and decoupler for multimode optical fibres - has connecting planar waveguide of specified height and width, with front faces overlapping fibre cores
Inventor: WITTE HANS-HERMANN DIPL PHYS D
IPC: G02B6/28
Filed: 1979-04-26
Abstract: A single optical fibre (1) butts against a planar waveguide (4) at a coupling position (5), to which an outgoing fibre (2) and a decoupling fibre (3) are joined. All the optical fibres are of sheathed type with relatively thick sheaths (11, 21, 31). The waveguide is made of a transparent plastics that is resistant to ageing, and the (u) coupler is built on a substrate. Fasteners (5, 6), secure the fibres to the substrate, and at the coupling position the waveguide is of square section with its edge length the same as the core diameter of the sheathed fibre(s). Depending on the desired decoupling, the waveguide splits up into parts (4A, 4B), the first part (4A) leading to the continuation of the sheathed fibre (2). Thus the input and output coupling factors can be independent of one another.

Patent DE-2923480-A1 (DE)
Inventor: SPIES JOHANN
IPC: F25B17/00
Filed: 1979-06-09
Abstract: In a process for storing heat at low temperature, use is made of a first tank (1), which works as an accumulator feeding a heat exchanger or, possibly, being connected to an exchanger, and of a second tank (5) which is used on the one hand as a steam condenser and, on the other hand, as a water evaporator: this second tank is provided with a device pumping water and feeding fresh water thereto. The heat to be stored is conveyed, through a heat exchanger (3), to an aqueous solution of a substance having a very small partial pressure in the equilibrium vapor phase. The water evaporated by the heat transfer is condensed in the condenser and is eventually pumped away from the system. The substance dissolved in the aqueous solution (2) is enriched in the accumulator (1). Upon withdrawal of the heat stored from the accumulator, fresh water is evaporated by absorption of the ambient heat in the second tank (1); the solution remaining in the accumulator absorbs the steam by dissipating the condensation and dilution heat. The heat energy taken from the accumulator (1) through the heat exchanger (3) is used for feeding a consumer.

Title: Contact actuating device for relays - has actuating stops for sprung contacts in actuating plane and on either side of sprung contact terminal
Inventor: UNBEHANN DIETER
IPC: H01H3/00
Filed: 1980-01-10
Abstract: The actuated relay has at least one stationary contact terminal and an actuated, sprung contact terminal at an appropriate distance. The actuation takes place in a plane by forces of the actuator, resulting in contact making at a given point. Actuating stops (4,5) are used on the actuator proper (1) for the control of the sprung contact (2). The stops lie in the actuating plane and on both sides of the sprung contact terminal and near the contact making point (9,10). The stops are mutually spaced at a distance (16), corresponding to the contact spacing (15). When used in a relay with edge mounted armature the ratio between the contact spacing and the distance of the stops is identical to the ratio between the associated bearing distances (19,20), when the sprung contact terminal has an appropriate thickness (17).

Title: High pressure diaphragm reducing valve - has friction free operation provided by diaphragms which control inlet and outlet fluid flow
Inventor: BEHRENS LOTHAR
IPC: G05D16/06
Filed: 1980-01-18
Abstract: A high pressure gas or liquid reducing valve is designed with diaphragms to minimise mechanical friction and so improve the reproduceability of the unit. The reducer has two spools (D1,D2), each of which is coupled to a diaphragm (F1,F2). Inlet fluid is applied to the top diaphragm (P1) and outlet from the bottom one (P3). A secondary pressure tapping (P2) is taken from a line joining both diaphragm chambers. With the secondary pressure greater or less than the set level an external force (5) may be used to open or close the valve. When the secondary pressure equals the applied actuator force, the valve remains in the null position.

Title: Treatment device for powdery or granular products - uses thin corrugated bedding iron with peaks and troughs and many perforation holes and fitted with gas generating and removal devices
Inventor: CHRISTENSEN MOGENS AXEL
IPC: F26B17/26
Filed: 1980-03-15
Abstract: The treatment device for powdery or granular products has a largely horizontal thin corrugated bedding iron which has mainly parallel waves comprising peaks and troughs located next to each other. It has a number of perforation holes positioned next to each other which are equally distributed over the surface of both peaks and troughs. There are product feeders and vibration devices to oscillate the bedding iron and gas supply devices generating a gas flow through each of the perforation holes of the bedding iron to fluidise the product.

At least the larger part of the perforation holes are formed so that the gas flow passing through them is given a horizontal flow component which points in the direction of the product removal devices.

Title: Prodn. method for mouldable structures - forms honeycomb shapes without cutting by fitting connecting surfaces alternating with connection free surfaces, folding and cutting
Inventor: SIEGEL ROLF
IPC: B31D3/02
Filed: 1980-05-08
Abstract: The mouldable structures with a potential honeycomb character are made from a material supplied in rolls and shaped without cutting. A pre-set number of connecting surfaces alternating with surfaces free from all connections are produced in a length ratio of 1:3 over set longitudinal sections always alternating on the front and rear side with the final number of connecting surfaces and surfaces free from connections not necessarily being identical on both sides. Subsequently a fold is achieved in a continuous process in the beginning and end areas of all longitudinal sections covering the largest possible area of all longitudinal sections equipped with connecting surfaces and surfaces free from connections by the unprocessed sides of the following longitudinal sections in each case. Finally the two sections are inherently connected and the folding points are removed by cutting.
