Title: Centrifugally operated friction clutch
Inventor: FROHWEIN FERDINAND
IPC: F16D43/18
Filed: 1981-06-27
Abstract: In this centrifugally operated friction clutch, three segment-shaped centrifugal weights (15) are provided for the transmission of the torque, the flat surface of these centrifugal weights lying opposite a driving hub (10) and their curved surface having a friction facing (16). Corresponding to the friction facings is a cylindrical friction surface (21) of a driven part (20). The centrifugal weights are held centripetally against the hub by helical springs (17) under tension as long as the centrifugal force is lower than the tensile force of the springs. There is a leaf spring between each of the flat surfaces (11) of the hub and the corresponding flat surface of each centrifugal weight, this leaf spring being bolted firmly to the hub at one end and to the centrifugal weight at the other end. Longitudinal and transverse displacement of each centrifugal weight is thus prevented during the operation of the clutch but radial movement of each centrifugal weight during coupling is unhindered. <IMAGE>

Patent DE-3130078-A1 (DE)
Title: Sound transmitter without standing waves
IPC: H04R1/28
Filed: 1981-07-30
Abstract: The invention makes it possible to transmit the indirect sound without standing waves in indirect sound transmitters (loud speaker enclosures) (see description). The advantages which can be achieved by means of the invention consist in that in loud speaker enclosures having conventional indirect sound feedback (bass reflex enclosures, transmission-line enclosures and exponential enclosures), standing waves form in the interior of the housing which in the reproduction of music at the lower frequencies simulate a bass component which is not contained in the original music. As a result, the range of music between 20-250 Hz (Hertz) is reproduced in a very differentiated and clear manner, for example in the case of organ notes, bass guitar, piano and so forth.
Patent DE-3130686-A1 (DE)
Title: Portable machine tool with rectilinear guidance mechanism
Inventor: MORIGUCHI SEKI
IPC: B27F5/02
Filed: 1981-08-03
Abstract: In a portable machine tool, for example an electric portable planer or the like, a rectilinear guidance mechanism (60) is provided for the tool (1) for rectilinear machining. The mechanism contains a rotary roller (7) which is fastened to the housing (10) of the tool in such a way that the roller is pressed flexibly against the surface of the workpiece (2) to be machined as soon as the tool is applied. The rotary roller is made of a material with a high coefficient of friction and contains a multiplicity of grooves (71) which are parallel to one another and extend in the rectilinear feed direction so that a relatively high friction force develops between the bearing surface of the rotary roller and the surface of the workpiece as soon as the tool moves in a different direction to the straight feed direction. The contact force can be adjusted if necessary. Instead of the rotary roller, stationary pressure or contact parts with longitudinal flutes can also be used, which likewise impede a lateral movement. If the rectilinear guidance mechanism (60) is not needed, devices for swinging it away or for removing it can be provided. <IMAGE>
Patent DE-3132416-A1 (DE)
Title: Use of thiocarbonic and thiophosphoric acid derivatives as resist
IPC: D06P1/649
Filed: 1981-08-17
Abstract: Water-soluble organic derivatives of carbonic acid or of phosphoric acid with a mercaptan group capable of mesomerism or tautomerism can be used individually or combined as resists (reserving agents) for preparing white and coloured resists underneath phthalocyanine condensation dyes (ingrain types) on cellulose fibre materials. To form coloured effects underneath the phthalocyanine dyes it is possible to use reactive, azoic (azo development), vat or leuco vat dyes or pigments. If thiocyanates (rhodanides) are used in the first print resist in addition to the mercaptan derivatives, the result is an enhancement of the resist effect. The development and fixation of the resists is effected by means of hot air or steaming; they can also be effected using a two-phase wet-fixing process involving a hot alkaline liquor. The novel method serves to simplify the coloration of Africa prints.
