Title: Disc record playback with scanner surface polishing - has grinding groove support next to record turntable, axially shiftable on drive motor shaft
Inventor: HELLER JUERGEN
IPC: G11B3/56
Filed: 1973-06-29
Abstract: The playback appts. uses pressure scanning of a rapidly rotating record disc by means of a mechanical scanner so adjustable that its longitudinal centre line is at an angle between 5 and 15 deg. when used for playing and at 0 deg. when used for polishing of the surface, as in 2053866.

Title: In and out storage system for pallets - traverser trolley with feed and offtake conveyors serves distributor
Inventor: SCHEFFLER HELLMUT
IPC: B65G1/04
Filed: 1973-08-23
Abstract: In and out storage system for pallet handling etc. consists of a tandem type travelling trolley whose two conveyors feed out onto, and receiver from, associated conveying paths, respectively and simultaneously. The trolley travels past a distributor formed from three, longitudinally parallel runs of conveying track which can be linked as needed with feed, removal or batching lines by a transverse travelling trolley. This facilitates routing of goods from the feed line to a selected batching point and thus on to a removal line. The first travelling trolley returns it to the conveying path thus completing the flow cycle. The conveyors on the trolley should be reversible roll tables, with the conveying paths formed from queuing tracks. The trolley serving the distributor should work on a 'first come, first deliver' principle.

Title: Hand-held wire stripping tool with two parallel hand-grips - with cutting knives at hinged end and helical spring at other
Inventor: PERRINO JOSEPH A
IPC: H02G1/12

Title: Series connected triac or thyristor voltage equalization - involves inductance connected in parallel to series network
Inventor: BAUM WALTER DIPL PHYS
IPC: H02M1/00
Filed: 1974-04-09
Abstract: To equalize the voltage drop occurring across each device, a parallel resistance series network, or capacitance, resistance network is used. The problems arising from heat production and component value drift are ameliorated using an inductance in parallel with the series network, divided equally depending on how many series elements are used. It is connected at the dividing points to the nodes of the series network. The effect is to equalize the voltage drops as required. The triacs or thyristors may also be fired according to the voltage drops occurring in the various partial inductances. Another control signal may be taken from a secondary winding associated with the inductive network.

Title: Preventing corrosion and dust deposition by gas effluents - in glass-melting installation by injecting alkaline powders into gas ducts
Inventor: KIKUCHI MAKOTO
IPC: C03B5/167
Filed: 1974-09-16
Abstract: Corrosion of effluent gas ducts in glass melting installations is suppressed by uniformly introducing into the aggressive effluent gases a finely pulverised cpd., pref. an oxide or hydroxide of Mg,Ca,Na or K. The powder (5-10 mu, pref. 10 mu) is injected into the gases in an amt. of 1-10 mg.equiv/Nm3 (pref. 4-8 mg. equiv./Nm3). Corrosive sulphuric vapours and particles of low-melting pyrosulphates or bisulphate of Na,K, and also their carbonates, sulphates, etc. contained in effluent gases from glass-melting installations, react with each other when the temp. of the gas phase drops below 460 degrees C forming low-melting substances corroding the installations and forming deposits reducing the heat transfer rate. Iron is attacked by the pyrosulphates and bisulphates of Na and K with formation of FeSO4. The injection of the oxides or hydroxides of alkali(ne earth) metals neutralises the acid components of the gas effluents; high-melting neutral sulphates are formed; corrosion is prevented; deposn. of dust is reduced because the particles of the high-melting sulphates are not tacky of temps. below 460 degrees C.

Title: Blade holder for high-speed woodworking machine - lined with vibration-absorbing material for smoother cut
IPC: B27G13/02
Filed: 1974-02-05
Abstract: To reduce the transmission of unwanted vibrations from the machine (e.g. a high-speed machine) to the cutting blade, to reduce the unwanted vibration of the blade in the workpiece and to eliminate irregularities in the cut, vibration-absorbing material (rubber, plastic, lead, white metal, etc., etc.) is introduced in any or all of the relevant places - between the blade (3) and the jaws (6, 6a) holding it (i.e., 2e), round the edge of the jaws (i.e., 2c), and so on. Alternatively, one or both of the jaws can be made of vibration-absorbing material, or partial use of the material may be sufficient. The material used, while soft enough to absorb vibrations arising from the machine, must nevertheless be firm enough to hold the knife steady.
