Title: Improvements in or relating to photophonographic apparatus
IPC: G11B7/00
Filed: 1933-09-06
Abstract: 409,979. Optical sound-reproducing apparatus. RADIO CORPORATION OF AMERICA, 570, Lexington Avenue, New York, U.S.A. Sept. 6, 1933, No. 24712. Convention date, Oct. 8, 1932. [Class 40 (ii).] In a photoelectric sound-reproducing apparatus, volume control is attained by the use of a unitary device which controls simultaneously the brightness of the exciter lamp and the potential applied to the photoelectric cell. The system shown embodies an arrangement wherein the filament of the exciter lamp 2 is fed with current from a thermionic oscillator 3, the plate voltage of which is supplied by a rectifier 9 and smoothing device 13 .. 17. The transformer 10 which supplies A.C. to the rectifier also provides current for the filaments or heaters of the amplifier valves 4 ... 7, and for a lamp 11 provided for general illumination of the apparatus. The potential of the anode 23 of the photo-cell 1 is established by the drop across resistances 22, 21, and the potential applied to the cathode of the cell may be varied by means of a resistance 25, which is in series with resistances 26, 27 between the cathode and an earthed conductor 19. Thus the output of the cell may be controlled by varying the resistance 25, which at the same time correspondingly changes the brightness of the exciter lamp by varying the voltage applied between the plate and filament of the oscillator valve 3. The variable resistor may be placed in the positive instead of the negative connection to the photo-cell and the oscillator. Instead of supplying the exciter lamp with current from an oscillator, it may be fed with direct current from the rectifier and filter, in which case the resistor 25 would be arranged to control the lamp voltage directly. Alternatively, an independent source of power such as a storage battery may supply the exciter lamp, and a separate resistor is then provided for the lamp, and connected mechanically with the resistor 25, for simultaneous operation.

Abstract: 536,408. Internal expanding brakes. MATTERSDORF, G. Aug. 29, 1939, No. 24797. [Class 103 (i)] An internal expanding brake comprises at least three simultaneously applied shoes arranged with the friction surfaces in the same circumferential path, each shoe having end extensions by which it is pivoted and actuated respectively and which extend into the sectors of adjacent shoes. All the shoes may be arranged to act as leading shoes or one or more may act as trailing shoes, with the normal direction of drum rotation. In Fig. 1, three shoes 16 of T-section each have a forked extension 18 pivoted at 17 to a plate 11 which is bolted at 14 to the fixed axle casing of a motor vehicle and disposed in the mid-plane of the shoes. Extensions 20 at the other end of the shoes pass between the extensions 18 and engage pistons 21 of hydraulic cylinders that are pivoted at 25 on the plate 11. Pins 36 on the shoes normally contact adjusting eccentrics 33 pivoted on the plate 11. The cylinders are supplied by branches from a ring- shaped tube disposed on the outside of the cover plate of the drum. All the shoes are leading shoes or self-energising with the drum rotating in the direction of the arrow. In another construction two of the shoes are leading and the other trailing and the cylinder of the trailing shoes is of greater diameter than that of the others. All the shoe extensions are forked in this case and the trailing shoe has a double web. In Figs. 5, 6 two shoes 416 pivoted at 417 to the plate 411 are leading shoes with normal direction of drum rotating and two smaller shoes 416<SP>1</SP> pivoted at 417' are trailing shoes. All the shoes have double webs and the extensions 418, 418<SP>1</SP>, 420, 420<SP>1</SP> also are double or forked and are cranked as shown in Fig. 6.

Filed: 1945-09-25
Abstract: 600,860. Packaging. PNEUMATIC SCALE CORPORATION, Ltd. Sept. 25, 1945, No. 24844. Convention date, Oct. 11, 1941. [Class 94(i)] The machine operates by feeding a web of bagforming material an amount in excess of that required for one bag length, to! form a slack portion, drawing the slack portion one bag length while folding the web, retracting the slack portion the amount in excess of the bag length, sealing to form the web into an open bag, filling this bag and sealing, severing and placing the severed bag into a delivery chute 308, Fig. 12. The bag is shaped around a former 110, Fig. 6 and brush-like guides 122, 124, receives a charge of tea or the like from a hopper 192, sealed along edges 22, 24 by an electrically-heated bar 132 and severed by cutters 268, 278 actuated by gearing. Fig. 4 shows the adjustable means for delivering charges of tea from a hopper 172 through a rotatable, bladed member 180 the bottom of which rests on a reciprocating slide 188 intermittently cooperating with a hole 190 through which the tea passes into the hopper 192. The size of the hole is adjusted by threaded rods which, rotated by knobs 232, 234, cause the two relatively-sliding parts forming the hole to move apart, or together. The web 12 of, preferably, porous, fibrous material containing a thermo-plastic material is drawn from a roll 14 by rollers 32, 34, which pass a length in excess of that required for one bag length, and the web is pulled downwards one bag length by grippers 238 moving in slides 92, 92<1>. Before the sealing of two sides of the bag, the roller 34 is raised by a cam, and springs 70 cause the slack in the web to be withdrawn by moving a roller 54 through rack-and-pinion gear. The roll 14 is provided with a friction brake to control the un-winding. The roller 32 is intermittently rotated, to feed the paper forward, by pawl and ratchet mechanism 82, 84 and a link 96 coupled to one of the gripper-supporting members 92. The roller 34, Fig. 6, is lifted clear of the web during its withdrawal to take up slack. The roller 32 is prevented from rotating at this time by a spring-lever 106. The former 110 is yieldably mounted on a bracket 112 and moves upwards during withdrawal of the web. The pressure of the brush 124 is adjustable. The heating of the element 132 is thermostatically controlled. The co-operating member 134 is un-heated and is provided with a soft facial covering. The grippers 238 are cam-actuated towards one another when in a position to grip the web 12 and the slides 92, 92<1> are at the top of their stroke. Fig. 12 shows the bags being delivered into the chute 308 after being severed by the cutters 268, 270, by means of a pusher arm 310 on a shaft 312. The arm 310 is rocked by a cam 316 on a shaft 156<1>, arms 322, 326 and gears 324, 328. An electric motor drives the various shafts through belting, chain-and-sprocket gears and bevel gears and includes a clutch mechanism.
