Title: Improvements in and relating to the recording of sound
IPC: G10K13/00
Filed: 1936-01-17
Abstract: 455,122. Phonographic recorders. BORNHAUSER & CIE, P. J., 15, Fraunmunsterstrasse, Zurich, Switzerland. Jan. 17, 1936, No. 1563. Convention date, Dec. 13, 1935. [Class 40 (iv)] In apparatus for recording acoustic oscillations and comprising an electrically-operated diaphragm 7 adapted to close over one end of a sound-conducting tube 8 into the other end of which is fitted an acoustically-operated recording sound-box, the electrically-operated diaphragm 7 is larger than the diaphragm 9 of the recording sound-box so that the movement of the diaphragm 7 produces greater amplitude of movement of the diaphragm 9. The microphone 1 and associated apparatus may be located at a distance from the recording apparatus and the tone arm 13 is provided with a movable flap 21 which, in the open position, allows speech from the distant transmitter to be heard by the supervisor of the recording apparatus. The tone arm is traversed across the record 19 by a half nut 14 engaged by a screwed spindle 15 driven by gears from a motor 12.

Title: Improvements in or relating to thermionic valve circuits
IPC: H03D7/08
Filed: 1943-02-01
Abstract: 562,325. Valve modulating or demodulating circuits. STANDARD TELEPHONES & CABLES, Ltd., EYRE, C. M. LE G., and GILDERDALE, J. O. Feb. 1, 1943, No. 1636. [Class 40 (v)] An impedance is provided in the cathode lead of a frequency changing, demodulating or modulating valve to provide negative feedback. The signal and the carrier wave are simultaneously applied to the input and the valve is fed with such amplitudes and is so biased as to operate over a curved portion of its characteristic. The modulation product output is taken from across the cathode impedance, a blocking condenser being provided if necessary, and fed to a coaxial transmission line, the impedance of which is substantially matched. The Figure shows a frequency-changing valve V with a band filter L2, C2, L3, C3 for a radio frequency input and the local oscillator input applied to coupling coil L1. The intermediate frequency output is taken from across the cathode resistance R1 and is applied to coaxial transmission line T, condenser C1 shunting the RF input. Resistance R1 is so chosen that the line is matched to the effective output impedance of the valve. The valve is preferably of the type having a screen grid and de-coupling of the anode and screen circuits is effected by resistances R4, R6 and condensers K1.

Title: Pierce unit and means for setting up the same
Inventor: WILLIAMSON FLOYD MITCHELL
IPC: B21D28/24
Filed: 1966-01-13
Abstract: 1,089,163. Punching. DI-DRO ENGINEERING CO. Jan. 13, 1966, No. 1652/66. Heading B3W. A fluid-actuated piercing unit is designed to facilitate the alignment of the punch and die and has means for causing the punch to protrude through the stripper during the setting-up process. The unit comprises a body 10, a piston 14 which reciprocates in the body, and a piston-rod 12 which extends through a guide bush 18 at the lower end of the body and which receives the shank of the punch 24. A spring- loaded stripper 26 is mounted on the outside of the piston-rod. The piston-rod 12 is biased to a retracted position by a strong spring 16, and is operated for a piercing operation by pressure fluid admitted through a port 48 in a cap 42 which closes the upper end of the body. The device for causing the punch to protrude through the stripper for setting-up comprises a pin 56 which is guided in the lower part 46 of the port in the cap 42 and which has a head 54. A block 40 is temporarily attached to the cap 42 by bolts 50 and has a bore 52 which receives the head 54 of the pin 56. A bolt 60 engages a thread in the block 40 so that by screwing in the bolt the pin 56 engages the piston 14 and forces it down against the spring 16. The punch then protrudes sufficiently to engage the bore 30 of a die 32. While the punch is so engaged with the die and with the body 10 engaging into support surface, bolt holes corresponding with the holes 70 are formed in the support surface, and dowelholes are formed to correspond with the holes 72. There is a hole 64, through the piston-rod 12, into which a peg may be inserted to maintain the punch in the extended position.

Filed: 1973-01-13
Abstract: 1431391 Endless conveyers N HAMY 22 March 1974 [13 Jan 1973] 1900/73 Heading B8A A portable transport system comprises a continuous belt formed of rigid segments 12 supported on an air bearing 16 and on a continuous guideway formed of air bags 18. Side seals 28 are provided between the segments 18 and diaphragms 24 of the bags 18. The diaphragms allow air to pass into the bearing 16, the air being pressurized by pumping stations located along the system. The diaphragms may be air pervious or they may have apertures 68 with valves. A continuous strap 22 depending from the segments 12 is driven by dual wheels 64 spaced along the strap. For unloading material from the belt, part of the system may be permanently tilted, Fig. 8, rollers 84 then supporting the edge of the belt segments 12. Alternatively, part of the air bag system may be supported on rollers 88, 90, the rollers 90 being drivable to tilt the system for discharge. Details.-The seals 28, when pressurized, take up the form shown in Fig. 2. An upper member 32 is secured at 360, 44 to segment 12 and a lower member 34 is attached to bag 18. A sealing flap 40, due to the pressure in the bearing 16, assumes the position 40a and air flowing through apertures in wall 50 of the lower member 34 passes from the member 34 at 52 and, after circulating as indicated, exits at 56. The members 32, 34 do not normally contact each other. Fig. 5 shows flexible couplings 62 between segments 12 and connections 60 between the segments and straps 22. The segments may have transverse air dams (72, Figs. 6, 10, not shown). Fig. 4 (not shown) indicates how segments (12) may be nested for stacking. The cover 36 carried by pressurized air may be removably disposed over the system or may be integral with the segments. Linear induction motors may drive the belt. Gas other than air may be used for supporting the belt.

Abstract: 1430876 Developing electrostatic latent images XEROX CORP 16 Jan 1974 [17 Jan 1973 30 March 1973] 01999/74 Heading G2H When an electrostatic latent image on drum 10 is developed with a carrier particle/toner particle mix, toner particles which have an insufficient electrostatic charge, or are charged to the wrong polarity, are removed from the developer by being caused to cling to roller 52 to prevent them from adhering to the background areas of the latent image. Two rollers may operate together, one removing particles of insufficient charge and the other particles of wrong polarity, or the roller may be divided into sections. The roller may act in conjunction with a development electrode, or may act as a development electrode. Where a sectional roller is used to remove both kinds of undesired particles, and also to act as a development electrode, it is rotated at such a rate that its average potential acts in development. Removal may take place in both cascade and magnetic development apparatus.
