Title: Improvements in or relating to electric driving mechanism for sound recording or reproducing machines
IPC: G11B19/28
Filed: 1921-12-29
Abstract: 194,831. Becker, P. A. Dec. 29, 1921. Starting and stopping. -In an electricallydriven sound-recording or reproducing machine, a switch in the motor-circuit is controlled by a centrifugal governor or the like, the switch being closed when the motor attains a predetermined speed (for example after being started by an auxiliary hand-switch) and opened when the speed of the motor drops below that limit (for example when the motor is short-circuited through an automatically-operated switch when the playing of a record is completed). Fig. 1 shows an arrangement of a governor-controlled switch, comprising a fixed contact n and a movable contact m mounted on a spring-actuated bell-crank lever h. One arm of this lever rests against the disc g of the governor, so that the speed of the motor a, acting through the governor. controls the switch in the manner described above. A circuit diagram is shown in Fig. 4. In this circuit, F is a push switch, normally open, and in parallel with the governor-switch m, n. To start the machine, the switch F is closed manually until the desired speed is attained. whereupon the circuit remains closed through the switch m, n. Alternatively, the machine may be started by spinning the turntable by hand. When the motor is short-circuited either by closing a hand-switch G or by the automatic closing of contacts w, w<1> by the sound-box on its reaching the end of the record, the diminishing speed of the motor causes the governor to break the circuit of the switch m, n. Fig. 2 shows an automaticallyoperated switch, corresponding to w, w<1>, in Fig. 4. This device comprises a bar s, pivotally mounted on a plug contact-member v and extending over the turntable into engagement with the central stub T. The bar, which has two contactrails mounted in grooves therein, carries an adjustable slider y, which makes connection between the rails and two contacts D, D<1> respectively. The circuit is closed when the arm D, which is pivoted at C, is moved by the soundbox against the member D<1>.

Title: Process for obtaining so from low-grade waste gases
Inventor: BANKOWSKI OTTO
IPC: B01D53/50
Filed: 1955-12-07
Abstract: In a process for obtaining SO2 from low-grade waste gases by scrubbing with aqueous ammonium sulphite solution circulating in a cycle, and recovering the SO2 by heat, the following modifications are made: (1) the sulphate content of the solution does not exceed that containing 80 g. sulphur/l., by withdrawing solution from the cycle and replacing it by pure calcium-free water and ammonia; (2) sulphate formation is kept to a minimum by preventing the presence of iron, aluminium, and calcium, by using pure calcium-free distilled water in preparing the scrubbing solution and by avoiding the use of iron throughout the plant and of aluminium in the hot sections; (3) the gas and solution are contacted in the scrubber for a time not more than ten seconds at a temperature not over 25 DEG  C.; (4) the desorption column has no packing such as Raschig rings.  The short contact time may be obtained by the use of bubble cap scrubbers, and the apparatus may be constructed of lead or non-metallic material, e.g. glass, polyvinyl chloride, or graphite saturated with phenoplasts.  The withdrawn solution may be extracted from the cycle after cooling the solution from the desorber in a heat-exchanger to which the solution also flows from the scrubber, and the water and ammonia may be added to the SO2-free solution from the lead-lined desorber, immediately before reuse for scrubbing.  The solution from the desorber is preferably divided into two streams, one being led to the top of the scrubber to which all the make-up water and ammonia is added, and the other being passed to the scrubber at an intermediate bubble cap tray.  The SO2 desorbed from the solution by direct and indirect steam is passed through a lead cooler, from which the condensate is returned to the cycle, is dried by conc. H2SO4, compressed and liquefied.
