Title: Improvements in and relating to the Recording, Producing and Reproducing of Sound.
Inventor: MUCKEY FLOYD SUMNER
IPC: H04R7/04
Filed: 1916-04-13
Abstract: 110,759. Muckey, F. S. April 13, 1916. Sound - magnifying appliances. The sound waves produced by a vibratory body, such as the diaphragm of a phonograph, are reflected by the walls of a resonance chamber in such a way that undesirable overtones are suppressed or subordinated, while the fundamental and lower overtones are intensified. The sound-box 10, Fig. 2, is of bell-shape with its larger end adjacent to the diaphragm 14, and its smaller end opening into a trumpet 16, if one is provided. The sound-box may be of circular or polygonal cross-section, or it may be corrugated, as shown in Fig. 8. The outer face of the diaphragm may be covered by an apertured plate 34, Fig. 19, forming a resonance chamber for reinforcing the diaphragm vibrations. This plate may have segmentalslots to permit undesired sound waves to escape without reflection. In another modification, bell-shaped chambers are provided symmetrically on each side of the diaphragm. Specification 1451/08 is referred to.

Title: Method of an apparatus for aligning a railway track
IPC: G01C15/00
Filed: 1973-02-06
Abstract: 1416270 Aligning railway track FRANZ PLASSER BAHNBAUMASCHINEN-INDUSTRIE GmbH 6 Feb 1973 [7 Feb 1972] 5778/73 Heading B7N [Also in Division G3] A railway track is laterally aligned by the use of a guide-beam, an emitter and a receiver for which is adjusted according to a fixed point of the track and the receiver moved and adjustments made in dependence on the distance travelled. As shown, Fig. 3, a laser beam emitter 2<SP>1</SP> is mounted on a trolley 17 which is positioned on a track 15, 16 adjacent to a fixed point 3 with respect to which a laser beam 4<SP>1</SP> is adjusted by a scale 20. A receiver 51 is initially aligned with respect to a fixed point 7 by rollers 21. The receiver is then moved forward for a distance Y, determined by an inductive pick-up on a wheel assembly 23. The laser beam emitter 2<SP>1</SP> is then adjusted in accordance with dimensions from a track plan 26 read by an operator and set into a computer 32. The pivoting of the laser beam emitter being controlled through a line 33 or a radio link 34, 35. The position of the receiver 5<SP>1</SP> is then centred by aligning the track with the rollers 21. The sequence is then repeated until the receiver reaches a position 39 at which the laser beam emitter 2<SP>1</SP> is transferred to a second fixed position and the receiver 5<SP>1</SP> aligned with respect to fixed point 3. Automatic alignment of the laser beam emitter 2<SP>1</SP> is effected by a unit 8, Fig. 3a, responsive to a signal from a distance recorder 40 over a cable 41. The signal is used by a timing control unit 42 to move a disc or punched card 48<SP>1</SP> from which track adjustment values are read at intervals determined by a step-by-step circuit 47 responsive to the timing control unit and transmitted by a unit 48 to a re-adjusting motor 49, Fig. 3c, for the laser-beam emitter 2<SP>1</SP>. The track-alignment is effected by the actuation of an hydraulic cylinder 22, Fig. 3b, through an hydraulic valve 54 controlled through an amplifier 51 by signals from radiation sensitive elements 37, 38 of the receiver. In alternative embodiments the alignment of the track is adjusted, with forward motion of the aligning rollers, by parallel movement of the beam receiver or emitter. In a further embodiment, two fixed reference points are used simultaneously and the track alignment determined by simultaneous pairs of chords.

Title: Ink distribution systems for letter-press printing machines
IPC: B41F31/00
Filed: 1941-05-05
Abstract: 545,346. Printing-machines. HUBER, Inc., J. M. May 5, 1941, No. 5833. Convention date, May 18, 1940. [Class 100 (ii)] In a letterpress printing machine employing ink solid at normal press-room temperatures, the printing cylinder and some of the ink distributing rollers are hollow and means are provided for circulating hot liquid in parallel streams through the cylinder and rollers and through a fountain heating device to maintain the ink in liquid condition at a substantially constant temperature. At each side of the press is a hot fluid supply pipe 12, 13, Figs. 1 and 2, connected by a cross header 11 to a supply line 14, and an exhaust pipe 22, 23 connected by a cross header 21 to an exhaust line 24. The pipe 12 connects by branches 15, 16, 17 to one end of a heating pipe or coil 10 in a water jacket J provided for the ink fountain F, to one end of the hollow distributing drum R and to one end of the printing cylinder P, the other ends of these parts 10, R and P connecting through branches 25, 26, 27 to the exhaust pipe 22. The fountain roller R 4  and distributing drum R 1  are similarly connected to the pipes 13, 23 so that the flow takes place through these parts in the opposite direction. The rate of flow is controlled by valves 31 in the branch pipes to the exhaust pipes 22, 23. In one form of apparatus for supplying hot liquid, Fig. 3, the exhaust line 24 is connected to a tank T from which the liquid is supplied by a pump B to the line 14. The pressure of the liquid is determined by the height of liquid in a tank T<SP>1</SP> connected by a pipe 37 to the tank T and a liquid supply pipe 39 is also connected to the pipe 37. The liquid in the tank T is heated by a steam coil 32 supplied through a valve 36 controlled by a thermostat 35. In another form of heater, steam is introduced directly into the tank T and in a further form the tank is heated by a burner, the gases from which pass through pipes in the tank. Higher working pressures may be used by substituting for the tank T\ a weighted piston in a cylinder connected to the pipe 37. The Specification, as open to inspection under Sect. 91 comprises also an arrangement in which the liquid in the tank is vaporized and, instead of hot liquid, a mixture of vapour and air circulates through the printing cylinder, and inking apparatus. This subject-matter does not appear in the Specification as accepted.
