Title: Cutting stone and siliceous minerals - with the help of fluorine and hydrogen and/or hydrocarbon mixtures
Inventor: PLICHTA PAUL
IPC: E21C37/16
Filed: 1971-10-29
Abstract: Stone and siliceous minerals are cut, sawed and mechanically worked with the aid of gaseous F2 and H2 and/or hydrocarbons rather than H2/O2. The heat of reaction H2/F2 is greater than H2/O2 and the operations can be successfully carried out under water or in vacuo. The reaction products are non-toxic. The F2 and H2/HC sources supply gas, under press. either to a single nozzle, being mixed immediately prior to reaching this nozzle or pref. the H2/HC is supplied to an outer ring of nozzles and the F2 to a jet in the centre of the ring. The nozzle arrangement is cooled and reaction products sucked away through a coaxially mounted device.

Title: Yarn winding - using common motor for spindle drive and common yarn tensioner
Inventor: BENSE WILLIAM MALCOLM
IPC: B65H59/38
Filed: 1973-05-28
Abstract: Designed for winding yarns on to a number of spindles in a vertical or a horizontal array, the common electric motor is linked to each spindle by an arrangement of belts, while the yarns pass round a common yarn tensioner before being wound into bobbins with the help of yarn guides and pressure rollers for each spindle. The purpose is to provide a constant winding speed for all the spindles matching the constant yarn feed speed, particularly for continuous synthetic yarns, with an equal tension to develop even and consistent wound yarn packages.

The amplifiers are all similar. this arrangement has the advantage of improving the signal-to-noise ratio by a factor approximately equal to the square root of the number of amplifiers. The method is useful for determining a very small current or voltage and lengthens the periodicity of the fluctuations.
Patent DE-2362897-A1 (DE)
Title: Dispenser for segments of double side adhesive tape - hand held dispenser is rolled along surface to deposit segments either singly or at predetermined distances
Inventor: GUTZEIT JUERGEN
IPC: B65C11/00
Filed: 1973-12-18
Abstract: A hand held dispenser enables double sided adhesive tape to be deposited in small segments. The adhesive segments are contained on a roll of paper type and are spaced at fixed distances. A leaf spring holds the tape in contact with a feed roller. When the dispenser is held such that the roller is in contact with the surface, onto which the segment is to be deposited, forward motion produces tape feed. A guide causes the leading segment to be transferred to the roller surface. When contact is made with the surface for deposition, the pad is transferred providing that the contact adhesion is greater than that which the segment exhibits in relation to the roller. The roller is serrated or grooved for this purpose.

Title: Roll back type snow fence - has vertical tubular uprights held by tension wires and pegs with stretched netting between
Inventor: BEILHARZ WILHELM
IPC: E04H17/10
Filed: 1974-03-27
Abstract: The netting is preferably plastics and is formed of horizontal and vertical strips one to four centimetres wide leaving rectangular gaps between them of a rough size of three times five centimetres. The netting is attached to the uprights by means of a U-shaped bracket made, for instance of strong iron wire. The width between the two sides of the bracket is a little more than the width if the horizontal meeting strips. The two downward-bent ends of the bracket are inserted into holes in the uprights. That part of the netting enclosed by the bracket is protected by a plastics strip. The ends of the bracket rest against the inside surface of the tubular uprights; alternatively the ends may go through the uprights and emerge through two holes opposite, where the ends bend down also at right angles to rest against the outer surface of the uprights.

Title: Rotary-printed sheet smoothing mechanism - has drum segment from which sheet is pulled off
IPC: B65H29/52
Filed: 1974-06-06
Abstract: The mechanism pulls sheets smooth that have been printed by a rotary press, being mounted between the last printing mechanism and the discharge mechanism and having a curved surface over which grabs engaging with the sheet leading edge pull it. The curved surface is formed by a segment of a drum (6). This is so mounted in the path (5) of the sheet (1) that the latter is pulled off the drum along a line which is at an angle (18) to the drum tangent (19) at this point. The drum can be mounted eccentrically in its bearings, and means can be included to generate all electrostatic attraction force between drum and sheet. Alternatively this force can be generated by suction or a jet of compressed air.

Title: Enzymatic control of cpds. in soln - in a dual filter appts. with intermediate enzyme treatment stage
Inventor: EDWARDS RONALD ALEXANDER NIXON
IPC: A23C9/00
Filed: 1974-07-15
Abstract: The proportion of cpd. (I) in soln. is controlled by (1) filtering to remove large particles (II), (2) adding a soluble enzyme of mol size greater than (I) but lower than (II) to the filtrate to convert it, (3) filtering to remove the enzyme and (4) combining the filtrate with (II). The solution is pref. milk, (i) is lactose and the enzyme is beta-galactosidase. The removal of (ii) increases enzyme activity. The enzyme is easily recovered from the soln. examples are hydrolysis of lactose for special diets, control of glucose in egg white to control colour.

Title: Hollow, smooth sided anchor - has pivoted, hollow flukes partially filled with granular ballast to alter centre of mass
Inventor: POPPE HORST
IPC: B63B21/44
Filed: 1974-10-10
Abstract: The anchor has flukes pivotted about a transverse axis at the end of the anchor shaft, with the flukes having a triangular cross section. The flukes are hollow and watertight, with their sides formed by flat metal plates. The insides are partially filled with a granular ballast. As the anchor is hauled in the ballast falls to the bottom of the hollow flukes and thus holds them parallel to the shaft. When the anchor is dropped to the seabed the ballast slides in the flukes to alter the centre of mass and enables the flukes to dig into the seabed, especially when the ballast falls into the tips. The anchor is simple to make, using only flat metal sections with simple weld seams.
Patent DE-2449975-A1 (DE)
Title: Infinitely variable mechanical transmission - with rotating perforated disc and toothed sphere transmitting rotation to rack
Inventor: HOMBERGER INGOLF DIPL KFM
IPC: F16H3/42
Filed: 1974-10-22
Abstract: The transmission consists of a perforated disc, rotated by a drive, with a toothed sphere, which runs over the disc, with its teeth engaging in the perforations. The sphere is displaced on the disc, at a different RPM, and transmitts this RPM onto a perforated rod, positioned above it, via its teeth, which engage into the perforations. The sphere is retained by two perforated guide rods, positioned on either side so as to be movable, but in one direction only. With a displacement of the guide rods and the power transmission rod, the sphere is moved diagonally across the disc.

Title: Timber cutting clamping appliance - uses two pairs of adjustable grab jaws
Inventor: OSSWALD DIETER
IPC: B27G19/08
Filed: 1974-12-10
Abstract: The appliance is for the retaining of tree trunks, during cutting, using grab jaws, enclosing the timber. A pair of grab jaws (1, 2) is positioned on either side of the tree trunk at a distance to the cutting saw. The grab jaws are displaceable parallel and towards each other, and are carried on support arms (5a). When in use, the arms extend in an almost horizontal direction. The arms are prismatic shaped, and have pref. rectangular or square cross sections. The grab jaws are displaced by pneumatic or hydraulic adjusting elements (4). One of the grab jaws is connected to a scale (11), and has a displaceable indicator (12), connected to the second jaw of the same pair, to indicate the distance between the clamping surfaces (21), and thereby the diameter of the timber (9).
