Title: Mine drill test bore torque indicator - houses friction members and indicator marking sheet or moving scale
Inventor: AMBROCK H DIETER ING GRAD
IPC: E21B3/02
Filed: 1976-06-15
Abstract: The drill for making test holes during mining operations employs a sleeve (2) with a drive block (3) inside, between front and rear torsion blocks (4) and/or an elastic layer (5) between the drive block and the sleeve. Hand grips extend sideways each side of the sleeve. This arrangement is used to establish the torque required for the drilling tool to be attached to the drive head (6) on the drive block. An indicator needle can be mounted on a carriage (7) which travels on a threaded spindle (8) parallel with the axis of the sleeve, which can trace a mark on a recording sheet (10) mounted in an opening in the sleeve. In an alternative design, a pointer can be externally mounted, which moves over a scale marked on the outside of the sleeve.

Title: Strip material uniform tensioning mechanism - has self aligning adjustable bearings bending roller over which strip runs
Inventor: MERTENS RUDOLF DIPL ING
IPC: B65H23/02
Filed: 1976-07-16
Abstract: The mechanism generates even tension in a strip of material such as paper, plastics, or textiles fed to a pair of printing rollers. Before the printing rollers is a further roller (10) with trunnions (14, 15) on the end faces (12, 13). The trunnions run in bearing (16, 18) which are adjustable so as to bend the roller and form a corresponding curve in the strip of material (1) running over it. The roller can be of material allowing relatively easy distortion, while having sufficient rigidity to holf the shape of the strip to within close tolerances. Each trunnion can run in two bearings, one of which (17, 19) is fixed and the other (16, 18) adjustable. The latter can be slid in a plane at right angles to the strip, while the former are of the self-aligning type.

When dismantled the table can be packed in a small case.
Patent DE-2641292-A1 (DE)
Title: Two stage fluid bed calcination - with high capacity first stage controlled to give incomplete oxidn.
Inventor: MACASKILL DONALD
IPC: C22B1/10
Filed: 1976-09-14
Abstract: Particulate ores, precipitates and concentrates are calcined to decompose hydrates and carbonates while volatiles are expelled using a first high capacity fluidized stage in which the introduction of O2-contg. gases is controlled to create an environment in which incomplete oxidn. will occur while the fluidized material is heated at about 1100 degrees F. The partially oxidized material is then transferred to a second fluidized stage in which sufficient O2 is added to complete combustion by heating it to >1100 degrees F. Used for fluid bed calcination of phosphates, limestone, Al silicates and alkaline earth minerals. The first stage can be heated with a low ignition point fuel, e.g. coal, which permits this stage to be operated at very high capacities, including dispersed phase fluidization. High grade CO2 is obtained from the second stage because the material has been dried and heated to just below its decomposition temp. in the first stage.
Patent DE-2642306-A1 (DE)
Title: Internal vibrator for compressing concrete - has unbalanced block rotating in tubular housing with seal retaining grease at bearing
Inventor: WANNER KARL DR ING
IPC: B06B1/16
Filed: 1976-09-21
Abstract: The internal vibrator for compressing concrete and other compositions comprises a tubular housing (1, 2, 3) with a conical slide face (9) along the inner wall for the unbalanced block (6) which turns in a bearing (5). Near this bearing (5) is a slightly resilient area (7) preferably formed by a known bending shaft (8). The centre point of the block lies in the axial direction preferably centrally on the slide face (9) and in this way the load of the bearing containing the unbalanced block is considerably reduced. The conditions which are altered in respect of the radial movement of the unbalanced block allow simple low-priced sealing means to be used which nevertheless effectively seal the interior of the vibrator from grease.

Title: Pump motor or compressor without pistons - has variable volume cylinder formed by two offset half cylinder assemblies
Inventor: TEUBNER ERICH
IPC: F01C1/40
Filed: 1976-11-18
Abstract: The machine has an end plate (5) rotating about an axis (1). Two casing walls (6, 7) perpendicular to each other project axially from the end plate and are solidly connected to it to form the end and two sides of a rectangular cylinder. A second identical end plate (8) rotates about an axis (2) parallel to but offset from the axis (1) of the first end plate. The second plate has two perpendicular casing walls (9, 10) projecting from it. The second end plate with its walls completes the enclosure of a rectangular space (11). As the two end plates with their projecting walls rotate about their separate axes the two pairs of walls slide relative to each other to vary the volume of the space (11) enclosed by them.

Title: Substrate plasma etching - with open metal cylinders around substrate wafers for even etching rate
Inventor: HASLER BARBARA
IPC: B01J19/08
Filed: 1977-08-29
Abstract: In a plasma etching process, a layer e.g. of photolacquer, is removed from the surface of a substrate byion bombardment in a plasma discharge. The substrates are supported during the etching process on a carrier plate inside an etching tunnel and are surrounded by a conductive metal cylinder which is open in the direction of the ion incidence. This prevents the etching rate on the edges from greatly exceeding that in the centre and ensures a uniform etching rate throughout the substrate.

Title: Accurately laid dry floor finish - uses chipboard mfd. with cement-bound chips
Inventor: WALSER ALEXANDER
IPC: E04F15/18
Filed: 1977-11-19
Abstract: Mfr. of DRY floor finishes (opt. with insulating layer) provides for use of accurately located, closely spaced, thickness gauges so that there is no need for expensive thickness-compensating layers when the raw floor base is made. Chipboards whose resistance to diffusion of, and penetration by, water is low are used for preparing the load bearing layer. They are made with hydraulic binders pref cement, as chipboards contg. phenolic resin or urea-formaldehyde resin as binder are unsuitable owing to their high water diffusion and penetration resistance.

Title: TV receiver incorporating stereo radio receiver - has two loudspeakers operating in pseudo-stereophonic mode when TV signals are being received
Inventor: MOORTGAT-PICK WALDEMAR DIPL PH
IPC: H04N5/60
Filed: 1978-02-16
Abstract: The T.V. receiver has both its radio receiver and LF amplifier designed to receive stereophonic signals. Two or more loudspeakers are located in a shared housing and acoustically decoupled from one another. The loudspeakers are driven in stereophonic mode when the radio receiver is being used and in pseudo-stereophonic mode for t.v.
