Abstract: 278.691. International Copperclad Co., (Assignees of Robinson, T.). Oct. 5, 1926, [Convention date]. Moulding - machines; rolling - machines. - A roofing or like building element consisting of a hardened plastic mass or core held in a jacket of fibrous material or paper which may be impregnated with water-resisting material is preferably moulded by rolling. The two sheets 75 forming the jacket are led between suitablyshaped rollers 54, 55, Figs. 1 and 9, and the hot plastic material fed between the sheets before their passage between the rollers 55 in which the shingle is moulded and severed. The mould cavities in the rollers 55 are preferably so contoured that the transverse periphery of the tile is constant and covering sheets of constant width can be made completely to surround the core and meet at the edges. The complete moulding machine is diagrammatically illustrated in Fig. 1. The covering passes from a roll or rolls 46 through a coating device 47 where it is water-proofed, through surfacing device 48 for the application of surfacing, granular or like material and through pressing rolls 49. The material is then led through cooling devices 50, 51 and guided to the moulding rollers 55 and co-operating adjustably-spaced pressing rolls 54, cutting rolls 52 being interposed if required. The rollers 54 have projections corresponding to the cavities in the moulding rollers 55, the covering being thereby shaped before delivery of the core material from the receptacle 56 thereon. The moulded tiles are severed and delivered on to a conveyer 58. The asphalt for the core is broken over a grill or screen 65, passes by a conveyer 67 to a breaker 68, thence to a pulverizer 70 and measuring device 63. The solid material for the core is also delivered into the measuring device 63 from the bin 59 and through a heater 61. Measured quantities of core material are subsequently fed into a mixer 73 heated preferably by steam and delivered as a plastic mass to the receptacle 56 for the moulding operation. The rollers 55 are provided with the cavities, slitting, and severing devices necessary for strip or single shingles of any desired shape and are readily removable. The asphalt may be mixed in a molten condition with the solid materials before delivery into the receptacle 56 which latter may be heated and provided with a mechanical feeding device.

Title: Improvements in or relating to devices for the compressed-air starting of internal combustion engines with free opposed pistons
IPC: F02B71/02
Filed: 1961-07-17
Abstract: 969,234. Free piston engines. SOC. CIVILE POUR L'ETUDE D'ENGINS A PISTONS LIBRES E.P.L. July 17, 1961 [July 19, 1960], No. 25755/61. Headings F1K and F1Q. A starting device for an internal-combustion engine having free opposed pistons with a cushion chamber in communication with the rear or outer end of each piston and having in each such chamber an open inlet port and an outlet port that is controlled by one of the pistons and is opened by that piston as it nears the end of its compression stroke, comprises valve means for controlling the introduction of compressed air from a reservoir thereof into the cushion chambers through the inlet ports and a connection including a check valve for coupling each of the outlet ports with a scavenging air reservoir of the engine. When the air pressure in the receivers 20 and 20<SP>1</SP> reaches the starting pressure the control cock 31, 31<SP>1</SP> is turned so that the air in the pipes 32 and 34 is discharged to atmosphere through the cock 31<SP>1</SP> and the port 37<SP>1</SP>. The cock 31 communicating with the piston 28 by a pipe 38 closes the exhaust to atmosphere at 37 and connects the pipe 38 with the air intake pipe 30 connected to the compressed air source. The air pressure acts on the piston 28 and displaces downwards the valve 25 against the spring 29. The seating 26 opens and connects the pipe 24 and spaces 23 and 23<SP>1</SP> with the atmosphere while the seating 27 is closed. The pressure in the receivers 20 and 20<SP>1</SP> acting on the annular surfaces connecting, on the one hand, the valve 17 with its control piston 18 and, on the other hand, the valve 17<SP>1</SP> with its piston 18<SP>1</SP> opens the valves 17 and 17<SP>1</SP>. The compressed air in the receivers 20 and 20<SP>1</SP> passes into the cushions or clearance spaces 9 and 9<SP>1</SP> and pushes the pistons 2 and 2<SP>1</SP> inwards. These pistons 2 and 2<SP>1</SP> then close the scavenging ports 10 and the exhaust ports 11 and the compression in the power cylinder begins. In the vicinity of the inner dead centre the starting air in the cushions 9 and 9<SP>1</SP> is discharged into the spaces 39 and 39<SP>1</SP> since the outer faces 8 and 8<SP>1</SP> of the power pistons free the ports 12 and 12<SP>1</SP>. Part of the air thus discharged passes from the spaces 39 and 39<SP>1</SP> through non-return valves 40 and 40<SP>1</SP> having a wide free cross-section into the scavenging air receiver 14. In this way scavenging air is available for the start of the scavenging which commences towards the outer dead centre of the first out stroke.

Title: Improvements in balancing signalling conductors with artificial lines
IPC: H04L5/14
Filed: 1923-10-17
Abstract: 208,515. Western Electric Co., Ltd., (Assignees of Hitchcock, H. W.). Oct. 17, 1923, [Convention date]. Inductances and capacities, measuring; electromagnetic current meters.- To adjust the balance between a telegraph cable 11 and its artificial line 14 definite impedance modifications of various types are made along the line and in each case a single standard impulse of E.M.F. is applied to the cable and line in parallel and the resulting unbalance current between the cable and line in series is recorded on an oscillograph as a " type unbalance curve '"; the curve of the normal unbalance current with the same impulse of E.M.F. is also recorded and is analvsed into components corresponding to the definite impedance modifications, the artifical line being thereupon modified accordingly. When the unbalance curves are to be recorded prior to adjusting the balance the switch 38 is opened, the switches 29, 29<1> are moved to the position shown to connect the primary winding of a transformer 16 across the points 12, 13, and the switches 30, 30<1> are moved to the position shown t oclose circuits through the armatures of polarised relays 22, 23. A key 20 is normally on its upper contact to close a circuit from a battery 21 to throw the armatures of relays 22, 23 to the left, thus providing circuits from a battery 24 through a vibrator a of an oscillograph 19 and through the apex 26 to the cable 11 and the line 14. Condensers 31, 32 prevent the flow of current to the cable and line when a steady current flows from the battery 24, and the vibrator a records the transmitted impulse. On depressing the key 20 a circuit from the battery 21 is closed to throw the armatures of the relays 22, 23 to the right when a contact is made by the rotation of a switch member 25 controlled in unison with the shutter of the oscillograph. This reverses the current from the battery 24 and causes an impulse to flow in parallel over the cable 11 and the line 14 at each closure of the switch 25, and the unbalance current between the points 12 and 13 at each such closure flows through the primary winding of the transformer 16 of which the secondary winding is connected through a multi-stage vacuum tube amplifier 17, 17<1> to the primary winding of a transformer 18. The secondary winding of this transformer is connected. to a vibrator b of the oscillograph 19. In preparing the " type unbalance curves " switches 33 - - 36 are thrown over to reduce the amplification. To eliminate irregularities due to interfering currents the key 20 is in each case depressed repeatedly, thus enabling the vibrator b to record the unbalance distinctly as a series of superposed curves.

Abstract: 162,010. Chappell Piano Co., Ltd., and Goldspink, A. E. Oct. 24, 1919. Expression-controlling; actions; blowing and exhausting air; wind trunks; tempo-regulating means; winding-mechanism; controlling handles. -In a player-piano, a single control-box disposed above the key-board in front of the hammer action, consists of a vacuum chest which contains devices controlling the motor, the intensity, the rewinding, and the accenting, the accenting control comprising primary and secondary pneumatics. The vacuum chest, the treble end of which is shown in Fig. 3, is divided into upper and lower chambers 13, 14 by a partition 12. The general intensity is controlled by a chokervalve 25 situated over a port 19 between thesuction at 22 and the duct 24 passing through the chamber 14 and leading to the striker-pneumatics duct 9. The bellows 75 operating the valve 25 may be mounted outside the control-box. A secondary pneumatic valve 26 controlling a second port 20 is operated independently and alternatively by two primary pneumatic valves 29, 28, either of which can be put into communication with the port 49 of the valve 26 by a slide-valve 46 connected by a rod 50 to a similar slide-valve at the bass end of the chest. The valve 29 is operated from the tracker-bar by a tube 34 and port 33 to cut off the tube 40 leading to the slide-valve from atmosphere in a chamber 31 and connect it to suction in the chamber 14, thus opening the valve 26 and giving automatic accentuation. With manual control of the accentuation, the valve 26 is normally open and is closed by putting the port 35 to atmosphere by hand, thus connecting the tube 41 leading to the slide-valve to atmosphere in the chamber 31. The motor-controls comprise a choker-valve 52, tempo-valve 54, and retard-valve 57. The rewind valve 55 is operated by admitting air to a tube 66 by rocking a valvemember 69 which at the same time admits air to tubes 60, 61 thus operating primary pneumatic valves 30 and putting tube 72 to atmosphere so that secondary valves 27 cutting off the suction from the treble and bass striker-pneumatics are closed. The control-box is secured over the ducts 9 leading to the striker-pneumatic, by wooden connecting-blocks containing L-shaped ducts, and bolts 82.
