Title: Improvements in and relating to Automatic Piano Players.
Inventor: WADE HAROLD
Filed: 1916-11-28
Abstract: 111,349. Wade, H., (Aeolian Co.). Nov. 28, 1916. Player-pianos; actions; expression-controlling. -Three pneumatics act upon a common moving board, one as a. motor under tune-sheet control, another as a variable brake under manual control, and the third as a motor under automatic or manual control. As shown, the pneumatics are mounted in two rows within a piano, and projections 3 on the moving boards act upon the hammer actions 4. Each pneumatic 2 is separately controlled by a valve 21 and a double bellows 14 from a tracker duct 12; the bleed hole 116 is controlled by the extended middle board 16 of the bellows 14, which also operates a valve 17 controlling the pneumatic 7. The resistance of these pneumatic brakes 7 to the motors 2 can be varied by means of a pair of slide-valves 63 with ports restricting the vent passages 26 and connected to a hand-lever in the key-slip. The tracker ducts 12 are also connected by tubes 27 with diaphragm recesses 29 in exhaust chambers 30, which are limited to separate ranges of notes, octaves for instance, and connected by passages 36 to exhaust pipes 134. The connexion of these pipes to the main exhaust is controlled either from the tune-sheet or from a series of push-buttons in the key-slip by means of valves in relay boxes, one at each end of the instrument. Valves 32 operated by the diaphragms control the pneumaties 10 through passages 33 so as to assist the pneumatics 2 for accentuating particular notes.. Other levers in the key-slip control the loud pedal and tempo or other device.

Abstract: 900,920. Making and attaching spouts. SEAL-SPOUT CORPORATION. May 18, 1960 [Dec. 14, 1959], No. 17506/60. Class 83 (2). In a method of mounting on a container wall a spout which has side flanges to be pushed edgewise through a zone of a container wall disposed perpendicularly to the path of the container during the mounting operation, the spout is picked up by a carrier at a spout feeding operation, carried to a spout inserting station, inserted into the container wall by a ram and the carrier then returns in a continuous path to the spout feeding station to repeat the cycle. A machine for performing the method comprises a frame F on which is mounted a conveyer which consists of a chain D and spacing blocks C which position the containers B. As the containers approach the spout inserting station I, one side is bent down by a rail J and as they leave the side is bent up by a rail K. A second conveyer L receives finished spouts from two spout forming mechanisms N and O and includes a plurality of units P which each comprise a spout carrier, a spout inserting ram, and an anvil. These units move through a path, a portion of which is adjacent and parallel to the path of movement of the containers. A strip of flat spout blanks h is fed to a pair of dies which bend the wings c relative to the body portion a and also form the prongs b by which it is attached to the body portion, after which the completed spout is moved on, engaged by the carrier of a unit P and severed from the strip. The unit P then moves to the spout inserting station where the ram and the anvil of the unit co-operate to force the wings c through the wall of the container, while the unit as a whole moves synchronously with the container. Specifications 799,563, 844,226 and U.S.A. Specifications 2,216,733 and 2,300,099 are referred to.

Abstract: 231,373. Haddan, R., (Regan, J. B.). July 22, 1924. Electromagnets.-In a train-carried indicator which is selectively moved from the neutral position to one or other of two indicating positions, the indicator is operated from a member 1 on a shaft 2 provided with an armature 3 rotatable between the poles 4, 5 of a permanent magnet 6. Symmetrically disposed projections 32, 33 on the armature poles serve to bias the armature to the neutral position shown in Fig. 6. The armature is locked in this position by a pivoted catch 9 entering a notch in a member 7 on the shaft 2. The parts 7, 9 are magnetized with adjacent parts of opposite polarity, so that they engage by magnetic attraction.

Title: Improvements in and relating to voltage stabilizers
IPC: G05F3/06
Filed: 1945-07-10
Abstract: 643,643. Automatic regulation. BRITISH THOMSON-HOUSTON CO., Ltd. July 10, 1945, No. 17542. Convention date, July 14, 1944. [Class 38 (iv)] In an A.C. voltage stabilizer comprising a normally saturated inductance connected across its input and output circuits, two normally unsaturated inductances coupled inductively with each other and connected in series with the input and output circuits respectively, and a capacitance arranged effectively in parallel to the saturable inductance, the winding of the saturable inductance serves as 'an autotransformer, the input circuit and the capacitance being connected to different points of said winding. In Fig. 1, to provide a stabilized A.C. voltage E7 despite variation of A.C. supply voltage EO and variation of load connected to E7 an unsaturated transformer 4 is connected in series with the primary of a saturable autotransformer 3 across the supply. A condenser 5 forms with the auto-transformer 3 a circuit having a capacitive reactance at the supply frequency. The stabilized voltage E7 is derived by combining the relatively stable voltage E1 across the primary of auto-transformer 3 with a compensating voltage E6 across the secondary winding of transformer 4. A suitable restricted core construction for auto-transformer 3 is described. The stabilizer provides effective automatic power factor correction since the input power factor is not materially affected by change of load power factor, although such change affects the output voltage level. The output voltage level is adjustable by primary tappings on auto-transformer 3. The following modifications are referred to: (a) Ends of the two windings on transformer 4 connected to separate tappings on auto-transformer 3 (see Fig. 9). (b) Stabilization of output voltage despite change of supply frequency by connecting in series with the load a series L.C. circuit resonant at the lowest operating frequency. Output voltage is then, however, no longer independent of load. (c) Stabilization of output voltage despite variation of supply fre. quency or load by coupling to the load through an auto-transformer 21 and condenser 22 (see Fig. 9), the primary of the auto-transformer 21 and condenser 22 having a net capacitive reactance at the normal supply frequency. (d) ,Suppression of odd harmonics by replacing condenser 5 by a number of series L.C. circuits 15, 18, 16, 19, 17, 20 (see Fig. 9), each connected across auto-transformer 3 and resonant at one harmonic, the combined capacitive reactance of these circuits being equivalent to that of condenser 5 in Fig. 1.

Abstract: 774,342. Straightening. SCHLOEMAN AKT.-GES. June 17, 1955 [July 8, 1954], No. 17585/55. Class 83 (4). A straightening roll shaft of a section iron straightening-machine is axially adjusted by means of a threaded bush which is arranged to be rotatable in the machine housing on the other end of the roll shaft from that carrying the roll and which serves as a housing for the axial bearing of the roll shaft, the bush being turned by a rotatably mounted shaft, which at one end carries a pinion engaging with the toothed rim of the threaded bush and which can be adjusted and locked from the opposite end, extending through the straightening roll shaft which is constructed as a hollow shaft. A hollow drive-shaft 2 carrying fast thereon at one end a straightening roll 1 is adjustable axially in a housing 4 by a bush 5, threaded in the machine housing, of an axial bearing 6. The bush 5 is turned, to move the shaft 2 axially, by means of a shaft 10 extending through the bore of the shaft 2. To effect the adjustment the shaft 10 is first moved axially against a spring 15 until a pinion 7 on the shaft 10 disengages a fixed locking tooth segment 16. Rotation of the shaft 10 by a hand-wheel 12 then turns the bush 5 through pinion 7, gear 8 and toothed rim 9 of the bush.

The frequency of the wave output of the valve is proportional to the air-flow rate. The output is fed to a pulse shaper 16 and amplifier 13 and fed to the fluidic device 1 which comprises an air input at 4 counteracting a fuel input at 2. No fuel flows into the manifold until a pulse is received from the amplifier which diverts the air-flow from pipe 4.
