Patent GB-305466-A (GB)
Title: A process for recording and reproducing sounds
IPC: H04M1/64
Filed: 1929-01-26
Abstract: 305,466. Siemens & Halske Akt.- Ges. Feb. 4, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Optical apparatus; photographic records; electric circuit applications.-Relates to processes for recording and reproducing sound, wherein an intentional distortion of the record is effected, the sound vibrations of greater amplitudes being reduced in scale on the record relatively to those of smaller amplitudes, and this distortion being compensated for during reproduction of sound from the record. According to the invention, during the making of the sound record (which is so distorted that all the vibrations recorded appear as having practically the same amplitude) a second record is made, which represents, comparing it point by point with the sound record, the variations in " amplitude limitation " on the latter. Both these records are used simultaneously in reproducing the sound, in such a manner that the auxiliary record effects the necessary compensation referred to above. Fig 1 shows the recording apparatus, in which is used an " amplitude limitation " valve r, to which is connected on the input side, through a transformer u, a microphone m, the output currents operating, through a transformer and an amplifier v<1>, a recorder comprising a shutter b<1> which controls a beam of light acting on a film f. On the output side of the valve is also connected as shown a rectifier g " provided with smoothing means." This controls the grid bias of the valve in such a manner that the amplification decreases with increase of amplitude of the currents generated by the microphone m. A second film a moves past a shutter controlled by an electromagnet l<2> receiving currents from an amplifier v<2>, which is connected as shown to the rectifier g. Thus a relatively flat curve is produced on the film a, and records the fluctuations in amplitude of tha sounds recorded on the film f. In reproducing, the two records f, a are used in conjunction with two photo-electric cells p<1>, p<2> in the manner shown in Fig. 2. The cell p<2>, currents through which are modulated by the " amplitude film " a, is connected through an amplifier v<2> to a resistance w inserted in the and circuit of a valve R, which is otherwise arranged in the usual manner so as to operate a loudspeaker t whereby the sounds recorded on the film f are reproduced. With the arrangement shown, the amplification ratio of the valve R at any instant. becomes the greater in proportion to the magnitude of the amplitude attenuation recorded on the film a, and thus a compensating action is effected. The speed of the film a during recording and reproduction may be considerably less than that of the film f.

Title: Improvements in and relating to Barrel Washing Machines.
Inventor: HORN CHARLES BRIGHT VAN
IPC: B08B9/08
Filed: 1917-02-27
Abstract: 113,336. Horn, C. B. van. Feb. 27, 1917. Cleansing barrels.-Barrels are carried step by step through a washing-machine by a carrier 40 driven by rack-and-pinion mechanism arranged to reciprocate it horizontally on rollers 41 mounted on cam-actuated arms 42, which raise the carrier 40 before its forward movement and lower it before its rearward movement. Barrels delivered to the machine by a conveyer are received upon arms 51 pivoted on the rear end of the carrier 40. When the carrier 40 moves forwards, the arms 51 turn and raise the barrel thereon into such a position that, when the carrier 40 is lowered, the barrel rests on rollers 52, 53, which rotate the barrel until a spring-controlled steam or hot-water nozzle GO pivoted upon the carrier 40 enters the bunghole. The delivery of steam or water from the nozzle 60 is controlled by a valve operated by an arm 65, which opens the valve when the nozzle 60 enters the bung-hole. A pipe 68 arranged above the rollers 52, 53 sprays hot water upon the outside of the barrel. The next upward and forward movement of the carrier 40 brings the barrel opposite brushes 71, which are automatically raised out of action during movement of the carrier 40. During the brushing operation, the barrel is rotated by rollers, upon which it rests. After the next forward movement of the carrier, the cleansing operation is completed by washing the interior of the barrel with cold water delivered by an antomatically controlled nozzle 100 pivoted upon the frame of the machine. The finished barrel is delivered by the carrier 40 to a runway.
