Exhibitors Herald and Moving Picture World (Apr-Jun 1930)

62 Better Theatres Section April 12, 1930 Excerpt from Exhibitors Herald 3/29/30 issue Now BesTone promises Sound-on-Film reproduction as good as their disc — nuff said! And what’s more — it’s Priced Right — wait for future announcement MODEL B DE LUXE PAT. PEND. A few foreign territories still available Attention, Bert Silver! I AM ENCLOSING REPORTS ON ALL Pictures I have run since putting in sound equipment. Personally, I think Bert Silver is all wet, as there were never any silent pictures made that will draw like talkies do. My father, Dr. F. M. Childs, was an oldtimer at the game. He used to send in many reports and letters from Villisca, Iowa. He was very skeptical about my putting in sound here in this town, which is even smaller than Villisca, but I cleared more the first month with talkies than he ever did in any one month in his twenty years at Villisca. He’s in California, now, but where they make ’em. Just a tip to many like I was. Borrow the down payment and buy a cheap but good outfit like the BesTone. Have not had a particle of trouble and I have the BesTone running two of the old Powers machines. You will hear from me often now as I am caught up on my work. — Austin Childs, Rex theatre, Hanover, Kan.

Current will flow at all times during operation from wire 40 to shaft 10, and thus to contact 41. Under the above mentioned normal conditions, current will flow from contact 41 to segment 21, wire 44, rheostat 28 and wire 45, to the motor (28). If the motor runs too slowly and the disc lags behind the platen, then contact 41 will ride on segment 32 and current will flow from the segment through wire 47 and resistance 48, to the contact (48) and through a portion of the rheostat to the motor. The resistance in this line being less than the main resistance of the rheostaot, the motor will speed up and bring contact 41 onto segment 31, whereupon the motor will resume its normal speed. If the motor runs too fast, disc 17 will speed up and contact 41 will ride on segment 33, whereupon current will flow to the motor through resistance 50 and the rheostat (29), until the parts assume normal position. If the load is suddenly taken off the motor, as by breaking of the film, then the disc (17) will speed up so quickly that the contact 41 will rest on segment 34, whereupon, the switch (52) being open, current will no longer flow to the motor. The motor is restarted by closing this switch, whereupon contact 41 will gradually move till it again rests on segment 31. Index fingers or pointers (54) are provided for the platen and disc, so that their relative positions may be visually observed. A New Sound Head • A new device for reproduction of sound-on-film recordings has been brought out by the Phono-Kinema Corporation. The sound head is called the Phono-Kinema. Information is that the original pat The Phono-Kinema Sound Head. ents cover those fundamental circuits between the photoelectric cell and the first triode tube, and that the other features are based on rights entirely clear of the peril of legal controversy. The head amplifier embodying the first circuit and coupled with a two-stage amplifier, is constructed on a chassis with all integral parts enclosed. It is pointed out that the cradle supporting the amplifier is designed to filter out mechanical vibration of the projection mechanisms, regardless of projection pitch. The entire amplifier chassis may be removed, and parts may be replaced with those purchaseable in the general radio and electrical market. Even the exciter lamp, it is stated, is pre-focused at time of manufacture in order to make all lamps interchangeable. The driving mechanism is asserted to be adaptable to most of the present installations of sound-on-disc equipment, having a vertical shaft rotating at 90 r.p.m. The constant speed drive sprocket in the sound head itself, is filtered to eliminate the effect of gear variations in both projector and sound heads, and in the chain drive, from the constant velocity of the sprocket, the object being to reduce variation in pitch. More About Tuned Pickups • It will be recalled that two or three issues ago, it was stated in these columns that the Auduk Company was , bringing out a tuned pickup, and that
