Title: Stereoscopic photography appts. using colour filter - is attached to camera to form composite image of scene from two viewpoints
Inventor: IHMS JAMES ERNEST
IPC: G03B35/12
Filed: 1977-01-15
Abstract: A first bundle of light rays from object impinges upon the front surface of light transmissive element (4). A second bundle of light rays impinges upon light reflective element (5). The second bundle of light rays is reflected by light reflective element (5) to the rear surface of light transmissive element (4) and defines a second image. In an embodiment the light transmissive element is a colour filter such as a red filter. Hence, the first bundle of light rays impinging upon the red filter is modified in colour content. The light beams serve as mutual colour filters for one another such that each of the reflected and transmitted beams of light of each impinging beam of light will be altered in colour content.

Title: Double walled drill pipe - has annular space filled by light-weight incompressible material able to transmit torque
Inventor: MUELLER REINER
IPC: E21B17/00
Filed: 1977-05-12
Abstract: A double-walled drill pipe for drilling holes for water wells and foundations has the annulus between the two walls filled with a material of adequate compressive strength to transmit forces between the walls. This is a simple way of reinforcing and stiffening the drill pipe and preventing damage to the inner pipe when the outer pipe is used to transmit the drilling torque. The filler has a much smaller specific gravity than steel so that the weight is only slightly increased. An outer steel drill pipe (1) is joined to an inner steel pipe (2) by joint rings (3, 4) also used to couple one pipe length to the next. The annular space (5) between them is filled with a reinforcing material (6), preferably a thermosetting plastics, or a soft metal or concrete. To improve the adhesion between outer and inner pipe and filler, the wall surfaces towards the annulus are coated with an adhesion activator.

Title: Positive displacement pump delivery control - holds inlet valve open during part of delivery stroke by adjustable element and using returning flow
Inventor: FLADBY TRON-HALVARD
IPC: F04B49/24
Filed: 1977-07-08
Abstract: The method for regulating the delivery of a positive displacement pump with automatic inlet (5) and outlet valves (6) is based on keeping an inlet valve open during an adjustable part of the working stroke of the pump pistons (2).

Title: Fabric wet treatment equipment - has series of roller conveyors to carry fabric through spray
Inventor: THIES ALFRED FRIEDRICH BERNHAR
IPC: D06B19/00
Filed: 1977-09-23
Abstract: The handling mechanism for textile fabrics in a wet treatment process uses >=2 roller conveyors, in line in the conveying direction, for movement through the treatment stages. There is a reel between the conveyors to carry the fabric from one conveyor to the other. At least one spray unit is located above the conveyors, aligned across their direction of travel, with a trap for the treatment fluid under the conveyors. The fluid recirculation system draws in fluid from the trap and pumps it to the spray. The system allows jet dyeing and similar processes to be applied to fabrics using a low vol. of fluid, keeping the fabric in a relatively dry condition, and imposing minimum mechanical force on the material.

Title: Noise screen wall sloping i profile supported beams - have triangular disc shaped end segments thicker than inside flange faces
Inventor: SPIEGLER ROLAND
IPC: E01F8/00
Filed: 1978-09-07
Abstract: The noise-absrobing and insulating elements for a wall have transverse I-profiles anchored in the sub-structure as supports, with intervening beams stacked on an incline, as in 2621808. At its ends (46) each element (42) has a segment cutting into its rear edge (57) and rear and base surfaces (45, 58), disc-shaped with right-angled triangular surface. This is slightly thicker (54) than the rear inside flange surface (51) of the I-profile to be engaged from behind by the element. Its hypotenuse face (55) completes the angle to the vertical relative to the rear face of the stack angle of slope (56) in the wall ( 41). This enables the advantages of sloped setting and wedging to be retained when narrow supports are used.

Title: Solar heat collector for air circuit - with heat exchanger at intake or outflow of absorber air flow
Inventor: KOESTER HELMUT DIPL ING
IPC: F24S10/30
Filed: 1978-09-14
Abstract: A solar heat collector for air as the heat carrier medium can be used for heating and/or cooling the air for buildings depending on whether heat exchangers are fitted in the air outflow and/or heat inflow duct to the absorber. This responds to small temp. differentials of 2-3 degrees C. It is ideal for use in windows and combines the room cooling functionism summer with the room heating functions in winter. Specifically absorber surfaces are built into double-glazed windows in a louvre arrangement to absorb the heat of the incident solar radiation; a heat exchanger is built into the top of each window and is connected to a floor heating system or a storage tank.

Title: DC decoupler with input signal producing magnetic field - causing spontaneous demagnetisation of inner region of wiegand wire thereby inducing pulse in output coil
Inventor: HERMSTEIN WOLFGANG DR ING
IPC: H01F38/02
Filed: 1978-12-13
Abstract: The dc decoupler has its input signal (U1) applied to an input coil (4) whose magnetic field acts on a Wiegand conductor (5) which in turn acts magnetically on an output coil (6) wound around it. The dc decoupling output signal (U2) is taken from the output coil. The Wiegand conductor consists of a ferromagnetic wire with memory properties. The wire is subjected to helical magnetisation by cold deformation. The longitudinal component of this magnetisation is antiparallel in the outer region of the wire to the component in the inner region. The wire has a diameter of about 100 microns and is a few cm long. The input coil's magnetic field causes the inner region of the wire spontaneously to demagnetise thereby inducing a voltage pulse in the output coil.

Title: Effluent water treatment using activated sludge - in circular tank with rotating aerator arm having air flow intensity altered around tank
Inventor: SCHREIBER AUGUST DR ING
IPC: C02F3/00
Filed: 1979-03-08
Abstract: The contents of the tank are aerated by a rotating aerator arm which is pivoted in the centre. The inlet comes from a settling pond and the aerator creates a rotational movement between inlet and outlt. The air inlets in the aerator are arranged so that the air throughput into the tank varies with the position of the aerator. The flow of liquid round the tank is controlled by a restriction between the inlet and outlet ports. Used esp. for denitrifying treatment of effluents. Allows for full treatment including N2 removal in a single vessel.
