Title: Improvements in and relating to gramophones and cinema sound reproducing machines
IPC: G10K13/00
Filed: 1918-11-02
Abstract: 141,090. Duffy, P. Nov. 2, 1918. Sound - boxes; tonearms; horns, arranging and supporting. - The sound-box of a soundreproducing machine is formed in two halves each supporting a diaphragm, to the outer surfaces of which is attached a forked stylus lever. Radial passages formed in the central part of the sound-box convey the sound from the respective diaphragms to two separate tubes which are universally jointed at their opposite ends to a supporting-bracket, and communicate with separate horns. One half of the sound-box, shown in Figs. 2 and 3, has two grooves F, G of semicircular section cut in its rear face I, one groove F communicating with the chamber C behind the diaphragm E. The other half of the sound-box, Figs. 5 and 6, also has two grooves F<1>, G<1> in its rear face 2, and the groove G<1> communicates with a chamber C<1> behind the diaphragm E<1>, the chamber C<1> in this case not reaching the rear face 2. When the two halves are secured back to back, two substantially radial circular passages are formed, communicating respectively with the diaphragms E, E<1>. The stylus lever L is pivoted in lugs H on one half of the sound-box, and is forked so that its arms K straddle the sound-box and are connected to the diaphragms. Tubes O, P leading from the passages F, G are secured to a ball Q, Fig. 10, mounted in a socket R adjustably clamped to a standard W. The ball has two curved passages f, f<1>, leading from the tubes 0, P to two tubes S, U swivelled on the socket R and arranged above and below the ball. The tubes S, U are connected to trumpets, or to tubes for conveying the sound to a distance. The socket R is formed in two halves, and an internal peripheral groove k in the socket is engaged by the ends of an horizontal pin h passing through the centre of the ball. The sound-box and the tubes O, P are thus permitted to rise and fall and to swing across the record.

Title: Improvements in heat-regulating system for type casting machine crucibles and the like
IPC: B41B11/76
Filed: 1919-01-21
Abstract: 141,257. Jackson, W. J. Mellersh-, (Cutler-Hammer Manufacturing Co.). Jan. 21, 1919. Metal pots and pumps.-In an electric heatregulating system for the metal-pots of type-casting machines &c. having independent body and spout heaters, the heat supplied to the body of the metal-pot is governed by an automatic temperature-controlled regulator, and the heat supplied to the spout is under the control of a manu. ally-operated switch whereby three conditions of heat may be obtained. The metal in the body of the pot is heated by two heaters 8, 9 having resistance elements 8', 9', and the spout is heated by heaters 10, 11. The current passing through the body-heaters is controlled by a thermostat 17, which may be of the kind described in Specification 139,111, [Class 38 (v), Electric switches &c.], and comprises a mercury bulb connected by a tube 19 to a Bourdon spiral 20 which actuates a pivoted contact lever 29 located between fixed contacts 32, 33. When the pot is to be heated up from a cold condition, the lever 29 is against the contact 32, and a circuit is completed from the positive line through contacts 32, 29, the winding of an electro-magnetic switch 37, and resistance 39 to the negative line. The switch 37 then closes contacts 40, 41, 42, the contact 41 completing a holding circuit for the switch 37. The closing of contact 42 completes the circuit for the bodyheaters 8, 9 from the positive to the negative line. When the temperature reaches a predetermined maximum, the lever 29 engages the contact 33, the winding of the magnet 37 is short-circuited, and the current through the heaters is interrupted. When the pivoted contact 44 of the manual switch is in the " off " position, the spout-heaters 10, 11 are disconnected from the line. When a high degree of heat is required in the spout-heaters, the contact 44 is cause dto bridge the contacts 45, 46, and the current passes directly from the positive line through the heaters to the negative line. A low degree of heat is obtained by causing the current to the spout-heaters to pass through a resistance 62. When medium heat is required, the contact 44 bridges the contacts 47, 48, 49, and the spout-heaters are controlled by the temperature of the metal in the body of the pot. The current passes either direct from the positive to the negative line through the switch 40 or, when the switch is open, through the resistance 52. The heat generated in the resistance 52 may be employed to heat the body of the metal-pot. Specification 141,812 also is referred to.
