Title: Pulse converters
IPC: H04Q3/42
Filed: 1969-06-04
Abstract: 1,272,837. Automatic exchange equipment; transistor monostable gating circuits. HASLER A.G. 4 June, 1969 [5 June, 1968], No. 28369/69. Headings H3T and H4K. Operation of the dial impulsing contacts, after a telephone connection has been made, is received as transient pulses in a receiver which includes a monostable multivibrator circuit used to gate an audio frequency voltage to the line. As shown, the line 1, 2 is connected to the primary winding 4 of transformer 3 through a blocking condenser 5. Two oppositely wound secondary windings 6, 7 are provided each connected at one end to the emitters of individual transistors 11, 21 and at the other end together to a voltage divider, which includes a reference setting capacitor. Normally conductive transistors 12, 22 are provided to short circuit the output of audio frequency generators 31, 33. In operation, opening of the looped line by the dial switch causes a pulse to appear at the emitter of 11 or 21 so the transistor conducts and a positive pulse appears on its collector. This pulse is transmitted to the base of transistor 12, 22 which cuts off and allows the output of generator 31, 33 to be transmitted to line 1, 2. When capacitor 18, 28 has discharged the transistors revert to their original states and the AF signal is short circuited. Since transformer secondary windings 6, 7 are oppositely wound the circuit will respond to both positive and negative pulses. The generators G may produce different output frequencies so that a receiver can respond more accurately to the initial pulses. Voice signal interference is minimized by selection of resistors 8, 9. The circuit could function with only a single AF generator in which case tone would only be transmitted for break pulses or make pulses, not both. In an alternative arrangement which provides an AF signal to the line for a single direction of pulse an extra winding is provided on the transformer and is connected through a relay contact to the AF generator. The relay operates when a signal from a bi-stable multivibrator is present together with a signal from the monostable multivibrator and the duration of operation is controlled by the monostable circuit, Fig. 3 (not shown). In a further arrangement two monostable multivibrators are used with the output of one feeding the input of the other, Fig. 4 (not shown).

Abstract: 951,724. Artificial respiration. W. RUSCH. July 24, 1962 [May 12, 1962], No. 28427/62. Heading A5T. A respiration tube for use in mouth-tomouth resuscitation is branched at its outer end, one branch serving for the introduction of air to the patient's lungs while the other is used for the patient's exhalation. In one form, the tube 1 is of soft, flexible rubber or similar material of sufficient length to be introduced beyond the patient's pharynx and it has a branch connection 4 leading to the inflation tube 3, the free end of which is taken in the operator's mouth. The exhaled air from the patient is passed out directly through an outlet 5. During the inflating phase this outlet is closed by the operator's finger and, to facilitate holding it, the outside of the tube is enlarged or provided with a flange. If desired, the forked branch-piece may be made separate from the insertable tube, one being a push-fit in the other, and the inflating tube may be made of smaller bore than the main tube and may be continued to the lower end of the latter.

Abstract: 229,398. Haddan, A. J. H., (National Cash Register Co.). Nov. 22, 1923. Printing - surfaces; inking - apparatus. - In machines for cleaning printing &c. rollers by means of pairs of moistened cleaning-rollers and drying-rollers on which the roller to be cleaned rests and is rotated by frictional contact therewith, one roller of each pair being driven in the same direction as the other but with a different peripheral speed, the rollers are all driven with equal angular velocities but one roller of each pair is of larger diameter than the other. The cleaned roller may be dried by absorbent belts travelling over pairs of rollers. The machine shown comprises a pair of cleaning-rollers 73, 74, rotating in a tank of benzine or other cleaning liquid 75, and two pairs of drying-belts 62 running over two pairs of upper rollers 40, 41 and two pairs of lower rollers 63, the shafts 64 of which are adjustable by means of screws 70 to tension the belts. The shafts 44 of the rollers 40, 41, 73, 74 are driven at the same speed by means of worm wheels 51 engaging worms 52 on a shaft 34 rotated by a pulley 32 and belt 33 driven by a motor 31, the roller 73 being of greater diameter than the roller 74 so as to have a greater surface speed, and the rollers 40 of greater diameter than the rollers 41 so that the right-hand drying-belt of each pair travels faster than the other. When laid upon the rollers 73, 74, the printing &c. roller 78 to be cleaned is consequently subjected to a rubbing as well as a rolling action, and similarly when laid upon the drying belts. Flat casings 79 are arranged between each pair of belts and connected by a pipe 86 to'a compressedair supply, the air being discharged through apertures 84 in the walls 80 of the casings on to the running belts to keep them in dry condition, and through apertures 87 in the tops of the casings on to the printing &c. roller 78 to assist in drying it. An auxiliary belt 98, Fig. 1, running over extensions of two of the rollers, so as to present a flat run, enables flat or non-circular printing &c. devices to be dried.
