Title: Precise variable quadrilateral cutting tool - is partic. for floor coverings and uses variable length cutting edges and linkages
IPC: G01B5/02
Filed: 1975-06-20
Abstract: The device is for the precise cutting out of four-cornered shapes, in partic, of floor-covering material, and is constructed to permit variation in the length of all four sides for more convenient and accurate working. The tool consists of four straight edges each joined to two others as its ends so that they pivot wrt. it. Each straight edge can be varied in length independently from the others. The outer edge of each side is a cutting edge. The variable length control element enables shape variation as well as size changes in conjunction with the two pairs of scissor linkages. The arms of the linkages may also be made variable in length for greater flexibility. The tool may be fixed in a given shape by locking devices.

Inventor: SCHULZE ERHARD
IPC: A63B69/06
Filed: 1975-06-27
Abstract: The sports training device consists of a three legged frame in which the two rear legs are linked together. The rear legs (11, 12) are linked to the front leg (13) by a pivot bolt. At one base the rear legs (11, 12) are fitted by pivots (16, 17) to shoes (18, 19). At the base of the front leg (13) is a wheel (20) the top of the front leg is extended to carry a seat (22).

Title: Shaft stepping mechanism for type head drive - has selective forward and reverse action produced by reciprocable pawl and selector rails
Inventor: THURNER RICHARD
IPC: B41J19/36
Filed: 1975-09-25
Abstract: The shaft stepping mechanism is esp. for driving a type head along a typewriter or like platen, and comprises a ratchet wheel (10) having a reciprocable forwarding pawl (12) and a retaining pawl (17).

Title: Rotary vane expansion engine - whose design minimises leakage, and wear of vanes and casing
Inventor: ECKARD SPURGEON EUGENE
IPC: F01C1/344
Filed: 1975-10-03
Abstract: The inside surface of the casing of a multi-vane rotating vane expansion engine is partially given a cylindrical profile (24), concentric with the rotor, arranged so that it constitutes a minimum clearance area with a peripheral length not less than 360 deg./N, where N is the number or rotor vanes, to reduce vane tip leakage. Exhaust ports (20) extend into the minimum clearance area, to minimise entrainment. High pressure fluid is injected through ports (26) in the min. clearance zone to improve sealing; is released through channels (28) as the vanes move outwards in the expansion zone where sealing matters less, minimising wear. Lubricant can be similarly added.

Title: Position detector for rotating shafts of powered vehicles - uses inductive pick=up and transition time independent circuit
Inventor: GLOSS ERWIN DIPL ING
IPC: F02P7/067
Filed: 1976-09-08
Abstract: A device for detecting rotating shaft position recognizes defined rotation angle ranges and produces corresp. signals using permanent magnets on a shaft disc inducing signals in a pick-up coil. It is designed to avoid disadvantages of transition times of the components of the associated circuits and to have less demanding limits on the edge detector output signal rise time than usual. The pick up signal is detected and converted in two edge detectors. One detector feeds the dock inputs of three bistables and the other feeds clock inputs of two further bistables in a register circuit.

Title: Single phase water gel explosive compsn - in which nitroparaffin is solubilised in aq perchlorate soln using alcohol solubilising agent
Inventor: MACHACEK OLDRICH
IPC: B01J19/06
Filed: 1976-09-28
Abstract: A single phase water gel explosive compsn. is produced by (i) mixing 40-90% of an aq., 50-80% concentrated alkali(ne earth) metal perchlorate soln. with 5-50% of a liq., 1-3C nitroparaffin, the amt. of nitroparaffin being in excess of that which can be solubilised in the perchlorate oxidiser soln., (ii) completing solubilisation of the nitroparaffin by adding 1-30% of an agent chosen from diols, triols and (m)ethyl and propyl alcohols, and (iii) adding to the mixt. 0-20% particulate Al, 0-5% void space forming material, 0-1.3% gelling agent and 0.02-0.03% of a crosslinking agent. The prod. compsn. is also claimed. The use of the alcohol stabilising agent allows small to large amts. of the normally insoluble nitroparaffin to be dissolved in the aq. gel system to produce both high and low sensitive compsns. which can be initiated without resorting to the use of large boosters. The nitroparaffin will not separate even after prolonged storing. High energy formulas can be prepd. which have sufficient sensitivity even at low temps.

Title: Anti-dazzle motorist's spectacles with small absorption zone - use rectangular darkened areas offset from centre to mask oncoming headlights
Inventor: BELMER RICHARD
IPC: G02C7/10
Filed: 1976-11-08
Abstract: Antidazzle spectacles for motorists have absorptional zones in each lens which are small with reference to total area of the spectacles. The absorptional zone (AZ1, AZ2) lies as a diaphragm protection outside the iris of the eye when the direction of vision is straight ahead. For driving on the right hand side the absorption zone (AZ1, AZ2) lies in the direction of vision on the left and for driving on the left hand side it lies on the right of the iris when the direction of vision is straight ahead. The two absorption zones (AZ1, AZ2) are offset by the same valve in relation to the direction of vision (M1, M2) of straight ahead.
Patent DE-2654788-A1 (DE)
Title: Screw thread formation on tapered work - has angle of feed of screw cutting tool altered to compensate for change in helix due to taper
Inventor: SLEIGH DAVID HAROLD
IPC: B23G1/38
Filed: 1976-12-03
Abstract: The method is for formation of a screw thread of constant pitch on a frusto conical workpiece by relative rotation of the workpiece (17) and thread-forming tool (24) so that the conical surface of the workpiece is held firm. The thread-forming tool (24) is moved axially w.r.t. the workpiece. The tool is simultaneously moved radially to the workpiece. The angle deviation, defined between a first plane normal to the axis of rotation of the rotating tool (24) and a second plane normal to the rotary axis of the workpiece, is also simultaneously altered. This causes the first plane on the rotary axis of the tool to be cut so that the required direction is adopted in order to produce a geometrically correct conical thread, to compensate for the increased helix angle at the narrow end of the work.
Patent DE-2659836-A1 (DE)
Title: Determination of amino acids in sugar beet - using fluoroescamine and/or (ortho)-phthaldehyde and measuring the fluorescence
IPC: G01N21/64
Filed: 1976-05-20
Abstract: Determination of aminoacids in sugar beet and/or prods. from sugar factories comprises colouring with fluorescamine (I) and/or with o-phthalaldehyde (II) and then measuring the fluorescence. Reaction is virtually instantaneous and fading and uncontrolled irradiation times are reduced. The presence of ammonia does not interfere with the (I) reaction cf. in the conventional ninhydrin method. The method is suitable for automation. In the presence of lead salts (I) is used as reagent with a bicine buffer, and in the absence of lead salts (by reaction with mercaptoethanol) and e.g., in the presence of aluminium salts, (II) is used together with a borate or bicine buffer.
