Title: Semiconductor laser for optical communication systems - with narrow band emission obtd. using interference filter
Inventor: HEITMANN WALTER DR ING
IPC: H01S5/028
Filed: 1974-03-06
Abstract: A semiconductor laser, esp. a double-heterostructure laser of GaAs-Ga1xAlxAs, has one of the two cleaved crystal ends forming the optical resonator provided with a highly reflecting mirror layer. To restrict the spectral range of the emitted radiation, the opposite end to the mirror end is provided with a narrow band interference filter which exhibits high transmission and low reflection of the desired emitted wavelength, but which is virtually impermeable to adjacent wavelengths. The mirror is pref. a dielectric with 100% reflection whereas the interference filter is a Fabry-Perot filter, or a Fabry-Perot multi-filter of partial, dielectric layers. Used for transmitters and intermediate amplifiers in optical communication systems. The laser radiation is restricted to a very narrow frequency band, and thus an optical transmitter can be built for very large band widths.

IPC: B60M1/30
Filed: 1975-02-15
Abstract: An expansion joint for the power rail ends in an arrangement for feeding current to high speed electrically railroad vehicles, uses a bridging piece to span the gap between the power rail ends. The ends of the hollow rectangular-box-section power rails, together with the abrasion resistant cover plate are curved to one side outwards, relatively to the long axis of the rails, and the "z"-section bridging piece, to which an additional layer of an insulating material is bolted, is pressed against the upper edge of the inner faces of the power rails where they are bent outwards.

Title: Paper distributor for single sheets - has square advance shaft and stack shearing rollers
Inventor: HAUSER FRANK WILLIAM
IPC: B65H3/06
Filed: 1975-09-08
Abstract: The paper distributor is for single sheets, and has a stack of paper between a lower (50) and an upper plate (52). The lower plate is inclined at a slight angle, and has a slot (58) near its lower end. The lower end (54b) of the upper plate is bent inwards towards the lower plate, to form an extraction aperture (56) through which only some of the sheets can pass. Two rollers (16, 20) and a chute are positioned below the extraction aperture, to move single sheets from the container. A square shaft (40) revolves, and its corners pass through the aperture, contacting the lowes sheet (46) in the stack. This allows the advance to bend up only the sheets emerging from teh aperture, and not the complete stack.

Title: Domestic waste water disposal pipe system - has collection tank with comminuting pump connected to vertical disposal pipes
IPC: E03F5/22
Filed: 1975-09-19
Abstract: The waste water disposal system for residential buildings uses vertical pipes. The outlet pipes for example from toilets, bathrooms or hand basins are not influenced by the slope. The draining points into the connecting pipes need not be arranged close to the points where these pipes are connected to the main, vertical pipes. The draining pipes (3) from bathrooms, toilets and hand basins are connected to a collector tank (4). The draining pipe (8) connects the tank to the vertical disposal pipe, and this draining pipe may have a pump (5) which acts as a comminuting device and can be located within the collection tank. The connecting pipe to the disposal pipe can have a smaller bore than the draining pipe from the bathroom or toilet to the tank.

Title: Self contained failsafe logic circuit - has blocking oscillator controlled by input and output transformers that saturate at overcurrents
Inventor: LOTZ ALFRED ING GRAD
IPC: H03K19/082
Filed: 1975-10-08
Abstract: The failsafe logic circuit for AC input signals sends them over separate transformers to rectifiers. The rectified inputs are then passed as control voltages to a blocking oscillator. Its output pulses are passed via an amplifier in the feedback transformer secondary circuit to the output. The input and output transformers saturate at unacceptably high currents. The outputs from the rectifiers are smoothed by a capacitor. The oscillator's transistor is chosen so that its controller potential has the opposite polarity to the input and output potentials at the transformers.

Title: Automatic beam balance for weighing free-flowing materials - has low centre of gravity and uses pointer deflection for fine weight readings
Inventor: UTIKAL GUENTER
IPC: G01G19/62
Filed: 1975-10-15
Abstract: The balance consists of a beam with a receptacle for the load and a scale for weights, and an indicating device for beam position. The system centre of gravity (S) is a little lower than is strictly necessary for the system equilibrium without load, so that pointer (8) deviation from equilibrium position can be calibrated in absolute mass differences between the weighted material and mass of the weights. There is a mass (M) acting as a counterweight at the lower end of the pointer (10). The sensitivity of the balance may be changed by varying the mass (M).

Title: Sewage pump assembly of pump and motor - has reducing equipment in intake region with holding and stripping elements
Inventor: BLUM ALBERT
IPC: F04D29/22
Filed: 1975-11-29
Abstract: Sewage pump unit comprising an electric motor and connected pump which is immersed into the feed medium. The assembly has reducing equipment in the region of the intake or connected before this to reduce and break up the intake material. In connection with the reducing elements there are holding and stripping elements which act on the sewage and oppose the suction of the pump. Because of their arrangement and the construction, the holding- and/or stripper elements are effective only for a short time at given periodic spacings. A holding- and/or stripper element is fitted to each reduction element and these are in the form of mechanisms to generate a pulsating intake flow.

Title: Metal framed fire retarding indoor partition - has plastic pansl with intermediate foam-filled gaps
Inventor: PFEIFER WERNER
IPC: E04B2/74
Filed: 1975-12-05
Abstract: The fire-retarding indoor partition wall may be an independent wall separating two rooms, or the rear side of a cupboard, serving as a room divider, made of a metal skeleton frame and paired covering panels. Intervening spaces are left between these, for insertion of material which foams out and fills them under the effect of heat. In these areas there are lengthways grooves in the framework, to hold barbed-ended battens gripping an intermediate section filled with this material. The intermediate sections (4) are made of PVC, or similar plastics of the requisite hardness. With regard to possible production and installation tolerances, their width is only slightly less than the interval (9) between the edge faces (8) of the two adjacent panels (3). This ensures prompt melting of the material, in the event of fire, no edge folding of the panels is necessary.
