Title: Automatic lathe
IPC: B23Q7/04
Filed: 1957-08-07
Abstract: 863,157. Automatic lathes. USINES TORNOS FABRIQUE DE MACHINES MOUTIER S.A. Aug. 7, 1957 [Aug. 15, 1956], No. 24854/57. Class 83 (3). An automatic lathe comprises a first headstock adapted to rotate and feed bar-stock and having machining tools arranged to operate on the stock, including a cutting-off tool to sever a workpiece, a second headstock arranged to take the front end of the severed workpiece, with at least one tool operating in conjunction therewith, and automatically controlled transfer means for moving a workpiece from the first to the second headstock. The first headstock 1, Fig. 2, carries a rotated stock-bar 3 which is guided at the front in a fixed rest 4 while the headstock is moved to turn the stock. The tools 14, 15, Fig. 1, for turning the stock and for parting, are arranged fanwise and controlled by cams 11 on a first cam-shaft 9. The latter is driven by worm-gears 7, 8, Fig. 2, from a pulley 5 and cross-shaft 6. The same shaft drives, through worm-gearing 7, 8, a second cam-shaft 10 which controls the tool operation for the second headstock. An indexible turret 19 is provided with axially fed end-working tools 18, 18a, 18b for the first headstock position. The second headstock 40 is arranged parallel to the first but reversed so that a cam-operated transfer arm 28 may convey the workpiece from headstock 1 to headstock 40. A second indexible turret 41 with end-working tools 42, 42a, 42b operates on the newly exposed end of the workpiece and is controlled by the camshaft 10. The tools in the turrets are axially fed by cams on the shafts 9, 10, and lever mechanism 21, 48, respectively. The finished workpiece is finally removed from the chuck 39 of headstock 40.

Patent GB-813672-A (GB)
Title: Improvements in or relating to electric selective systems
IPC: H04W88/02
Filed: 1957-08-08
Abstract: 813,672. Radio signalling. COATES, C., and LARDNER, W. E. Aug. 8,1957, No. 25033/57. Class 40 (5). [Also in Group XXXVIII] In a calling system of the kind in which frequencies, e.g. audio frequencies, are transmitted to select one of a number of receivers, there is an indicating means in each receiver which is held against operation by signals of particular frequencies, the transmitter having means for sending signals to prevent operation of all the receiver indicating means or all except one, or a selected group. A receiver is actually called by signals having frequencies eliminated by that receiver. Transmitter.-The transmitter, Fig. 1, comprises a radio transmitter 10 fed by variable oscillators 12, 13 through switches 16, 17. Another oscillator 18 generates a holding signal which is applied to the transmitter through switch 19. A microphone 20 is also connected to the transmitter for use when it is required to send speech. The switches 16, 17 and 19 must be operated so that there is no gap in transmission between the sending of the holding signal from oscillator 18 and the calling signal from oscillators 12, 13 for otherwise the receivers will respond. The switches may be mechanically interconnected for this purpose so that switch 19 is closed when switches 16 and 17 are opened and vice versa. Receiver.-An aerial 25 is connected -to an amplifier and demodulator 26 which produces an audio frequency output from the received signal. This output is applied to a path consisting of a first frequency selective network 27, amplifier 28, a second frequency selective network 29, amplifier 30, voltage-sensitive detector 31, relay 32 and a visual or acoustic indicator 33. Network 27 blocks the first frequency and network 29 blocks the second. Relay 32 is operated by the detector 31 when the signal applied reaches a predetermined low value and serves to close switch 34 to apply the incoming signal from demodulator 26 to a speaker 35. Operation.-Normally switch 19 is closed to transmit the holding signal which passes through networks 27, 29 to maintain the relay 32 inoperative. In order to call the receiver the oscillators are set to generate the first and second frequencies f and f2 so that the signal is completely blocked; relay 32 operates and switch 34 closes so that speech can be transmitted via speaker 35. Another receiver is called by another combination of frequencies, e.g. f 1 and f3, the second frequency passing through both networks 27, 29 of the receiver shown in Fig. 2 to prevent operation of the relay. All receivers are called by cutting off the transmitter oscillators. A breakdown at the transmitter causes all receivers to operate, or if a receiver is moved outside the range of transmission it indicates this by giving a continuous signal.

Title: Improvements in and relating to the treatment of arsenical pyrites or the like
IPC: C01B17/52
Filed: 1936-09-15
Abstract: Sulphur dioxide free from arsenic is obtained from arsenical pyrites by subjecting the pyrites to an oxidizing treatment at a temperature such that the arsenic escapes without any substantial combustion of sulphur and introducing the so treated pyrites into a roasting furnace, the arsenic containing gases from the first treatment being introduced into the roasting furnace at one end thereof and leaving at the other end in a countercurrent direction to the charge as a current of sulphur dioxide gases practically free from arsenic.  The first step may be conducted at 350--450 DEG  C. with the aid of heated air which has served for the cooling of the stirring arms of the roasting furnace and may be carried out in a chamber built on top of the roasting furnace, the bottom of this chamber being the usual drying hearth of the roasting furnace.  The roasting furnace may be of the type having superposed hearths and air-cooled stirring arms.

The filled pockets pass under a casing 5 and are emptied on to a second chain 6, the speed of which is sufficiently slower than that of the chain 1 to ensure that the gaps shall be filled. A change-speed gear may be provided for adjusting the speed of the second chain.
