Patent DE-2350969-A1 (DE)
Title: Locking and releasing mechanism for front and rear excavator loaders - has swivelling hook blocked loading tool and released by rope or solenoid
Inventor: SUBKE ROLF
IPC: E02F3/34
Filed: 1973-10-11
Abstract: This mechanism is used for locking the excavator tool when the scoop lifts some material. The scoop is released for unloading the lifted material so that the scoop can rotate downwards and the scoop is relocked after emptying. The front end of a rotating member carries a scoop which rotates in the bearing bracket. The bearing hook is closed by the spring loaded locking bar. The scoop is swivelled at the rear by means of the pivot which engages with the fork typre opening in the latching hook. The swivelling member is adjusted by means of the perforated adjusting plate to produce a certain specified working angle to the scoop. The lock accommodates the turning moment and it is held in the lock position. The scoop is released by the machine operator by releasing the locking bolt for releasing the latching member. The scoop swivels backwards after unloading and it is connected by its transverse pin to the nose and hence generates a moment for locking.

Title: Transformation of spoken sound into typed script - characteristic sound strength converted to corresponding electrical power
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: G10L15/26
Filed: 1973-12-04
Abstract: Each spoken letter generates characteristic compressions and rarefactions and given that it is spoken by the same person on each occasion the resultant sound strength can be relied upon to generate a corresponding voltage spurt or fluctuation in current flow. So in an arrangement comprising a microphone, measuring instruments, zener diodes, lamps and the like each sound will call into being a certain positioning of indicator, lighting of signal lamp, or other function. These indications can then be used, in turn, to operate the corresponding key of the alphabet. Since each sound contains many different frequencies the upper and lower frequencies are suppressed leaving a significant mean value.

Title: Stair lift for infirm people or children - runs along double railed track mounted on vertical wall parallel to ground
IPC: B66B9/08
Filed: 1974-07-15
Abstract: The lift carriage (20) has a frame (22) which travels along the rails (16, 18) mounted on the wall. The frame carries a first support roller (31) which runs along the top of the uppermost rail (16) and is positioned nearer the leading side of the frame than a second support roller (32) which runs on top of the lower rail and is positioned near the trailing side of the frame as it approaches the upward inclined sections of the rails on the stairs.

Title: Monocrystalline silicon prodn. - by zone meeting process using carrier rods with conductive coating prior to deposition process
Inventor: SANDMANN HERBERT DIPL CHEM DR
IPC: C23C16/22
Filed: 1974-11-20
Abstract: Silicon for semiconductor purposes is produced by depositing it from the gaseous phase on a silicon carrier rod with a coating of high electrical conductivity. The coating is such that it is stable enough to last through the deposition process but that it can be easily removed by the subsequent crucible -less zone melting. The a.c. flowing through the inductor coil required to initiate the zone melting operation is thus not higher than that required to maintain the heating of the molten zone. This results in a good thermal efficiency for the production of monocrystalline silicon. No preheating or other extraneous energy is required.

Title: Wood treating process using halogenated solvent contg. preservative - by maintaining a constant concn. of agents and amt. of solvent
Inventor: LIDDELL HAROLD GLENN
IPC: B27K3/50
Filed: 1975-04-09
Abstract: Wood is impregnated by (a) contacting the wood with a soln. in a halogenated 1-2C hydrocarbon on solvent contg. 2-6 wt. % of a wood preservative and 0.5-4 wt. % glycol, selected from ethylene glycol, propylene glycol, a corresp. Liquid polyglycol of M. Wt =4000 and/or a lower alkyl monoether of these, at ambient temp. to 140 degrees C, and at a pressure at least sufficient to maintain the solvent in a liquid state; (b) removing excess soln. from contact with the wood and returning it to storage means; and (c) heating the wood to >= b.p. of the solvent, condensing the vaporised solvent, and combining the condensed solvent with excess soln. The process also includes adding to the depleted combined excess soln. and condensed solvent to restor it to about the compsn. of the starting soln., a concentrate soln. contg. sufficient wood preservative, glycol and solvent to replace that lost in stages (a) to (c), the concentrate being 10-35 wt. % wood preservatives and 5-55% glycol component dissolved in the solvent. The treated wood contains little or no residual solvent, as compared with previous techniques, and is therefore free of surface bleeding. The treated wood retains the light colour and natural appearance of untreated wood. and does not darken with age.
