Title: Stone block sawing machine - tilts stone block at low frequency compared to that of sawing movement
Inventor: POELLMANN JOSEF ING GRAD
IPC: B28D1/06
Filed: 1979-05-30
Abstract: The stone saw has a support for the block (12) to be sawn and a saw frame with one or more blades (32). A feed mechanism is provided for the block in relation to the frame, which is moved by a drive at right angles to the feed direction. The drive also tilts the frame and/or the support, so that the base of the cut is convex towards each saw blade. The frequency of the tilting movement is low, compared with that of the sawing movement, typically less than 30% of it, and ideally 0.5 of it.

Title: Antimicrobial corrosion inhibitor compositions for iron and aluminium - contg. a benzoic acid salt and sulphamoyl-alkanoic acid cpd. (salt)
Inventor: GETTO ELMAR ING GRAD
IPC: C23F11/10
Filed: 1979-07-23
Abstract: New low-foam, microbistatic or microbicidal corrosion inhibitors in aqueous systems for iron, iron-contg. metals, aluminium or aluminium-contg. metals consist of a mixture of (A) at least one alkali, ammonium or 1-4C alkyl- or 2-4C alkylol-substd.ammonium salt of benzoic acid and (B) at least one sulphamoyl alkanoic acid deriv. of the formula (R1)(R2)N-SO2-R3-COOX (I) (where R1 is a 1-18C saturated or 3-18C olefinically or acetylenically unsaturated alkyl group (opt.substd. by methoxy or ethoxy gps.), 5-12C cycloalkyl, phenyl (opt. substd. by 1-3C alkyl, methoxy, ethoxy or halogen) or phenylalkyl with 1-95 (sic) C-atoms per alkyl group and R2 is H or R1, or -N(R1)(R2) is a piperidine, piperazine, pyrrolidine or morpholine ring; R3 is 2-5C alkyl; and X is H, alkali metal, or opt.substd. ammonium); the ratio of component (A) to component (B) being 80:20 to 10:90 w/w. Corrosion inhibitors have increased anticorrosive effect due to synergism for iron andaluminium and their alloys, and are low-foaming. They have an antimicrobial action affording protection to biodegradable substances in aqueous media, but their use does not have an adverse effect on the biological purification of waste waters. The compositions have an effect previously only obtainable with mixtures contg. nitrites.

Title: Addn. to automobile occupant safety belt - including separate loops of synthetic material allowing belt to slide freely
Inventor: BARTH MATHIAS OTTO
IPC: B60R22/00
Filed: 1979-08-02
Abstract: Series of separate elements of the same design which enclose and can slide along an automobile safety belt, form an added protection for the wearer in the event of a collision. The sleeves or loops are of fine leather, synthetic material, etc. and are either not at all or only loosely attached to each other. They are formed from strips, the centre sections of which are laid against the belt whilst the ends are folded over the other side of the belt so that one end overlaps the other. The inner face of the loop may have a lining of embossed synthetic film to facilitate sliding, whilst the overlapping ends have pads of synthetic foam, the surfaces of which have a self-clinging fastening tape. The belt can thus slide absolutely freely without the risk of abrasion of the wearer's skin, and it can be stowed much more compactly when not in use.

Title: Optical range-finder system - has row of photo diodes and uses tapped delay line to identify which diode is illuminated
Inventor: KRUEGER ARNO
IPC: G01S3/784
Filed: 1979-08-06
Abstract: The optical range finding system uses incoming laser signals i.e. from an IFF interrogator which are focussed by an optical system photodiodes. on one of a row of Each diode is connected to successive tapping points along a chain of delay circuits. The diode output propagates along the chain in both directions. The time difference at the ends of the chain indicates which diode gave the output, and hence the direction of arrival of the signals. After the amplification stage the maxima of both delay line outputs are detected and the time difference measured. This is converted to the equivalent arrival angle and stored. The stored angle is displayed and also used to control the direction in which a response is sent.

Title: Electrohydraulic flow medium control - uses torque and solenoid amplification and regulates mean discharge pressure by response of feedback circuit
Inventor: BUTCHER RAYMOND JOSEPH
IPC: F15B13/043
Filed: 1980-01-22
Abstract: An electro-hydraulic flow medium control valve, has a first amplification stage represented by a torque drive. It can adjust the position of the valve plug relative to two nozzles. There is a second amplification stage represented by a solenoid valve. It has very good response characteristics and a high resolution capacity. The coil responds to the control pressure of the flow medium to regulate the mean discharge pressure of the valve. The mean flow pressure operates the feedback circuit. The feedback responds to the mean pressure of the flow medium at the outlet of the valve to change the position of the valve plug in such a way that the setting of the plug by the torque drive is counteracted.

Title: Fabric dyeing and finishing - using fluid feed through container with almost insoluble granules to be mixed with main feed
Inventor: TRAPPE JOHANNES PROF DIPL CHEM
IPC: D06P1/00
Filed: 1980-03-11
Abstract: The treatment fluid for dyeing or impregnation of fabrics with a dyestuff or finishing agent, which dissolves in water with difficulty, has a secondary flow passing through a static zone where the dyestuff/finishing granules are contained. There is a filter to prevent the granules from passing into the treatment fluid where the fabrics are treated. As the unused treatment fluid is virtually colourless, the treatment of recirculating fluid is simplified. The system also provides a precise control of the amount of colour added to the treatment fluid.

Title: Antidazzle system using magnetic compass - rotating optical polarisers of two vehicles approaching each other until orthogonal
Inventor: SCHUBERT GYOEZOE
IPC: B60Q1/14
Filed: 1980-03-18
Abstract: The device has a magnetic compass with a non-magnetic disc coupled to it. The disc therefore rotates as the vehicle's direction changes and is connected to rotary polarisers in front of the driver and in front of the headlights. The required angle is reached when the axes of the polarisers of two vehicles approaching each other are orthogonal thereby preventing the light fron one dazzling the driver of the other. The compass ensures that this orthogonality is always attained since it links the position of the optical axes of the polarisers to magnetic north.

Title: Watercraft without a keel, in particular a so-called planing board (standing windsurfer)
IPC: B63B35/79
Filed: 1981-01-24
Abstract: The flow resistance of such watercraft without a keel is to be as low as possible in order to reach high sailing speeds. The object of the invention is therefore to reduce the flow resistance of a floating body of this type, which, as is known, increases in proportion to the size of the wetted area of the floating body, by increasing the buoyancy of the same, which results in a reduction in the wetted area. This object is achieved according to the invention by one or more continuous flow channels (2), extending in the direction of the longitudinal axis of the floating body (1), on the underside of the same and by a forebody arched upwards and located with its underside above the water-line even when the watercraft is stationary. During planing, air enters the top part of the flow channel or flow channels on the underside of the floating body starting at a certain sailing speed, as a result of which the buoyancy of the floating body is increased. A further advantage is the improvement in the course stability of the floating body due to the flow channel or flow channels. The depth and width of the flow channels are to be individually matched to the respective watercraft. The outlet opening (5) of the flow channel (2) lies above the water-line. <IMAGE>
