Title: Apparatus comprising a touch finger for automatic adjustment of the height of the burner in burner cutting machines
IPC: B23K7/10
Filed: 1952-05-22
Abstract: 735,875. Automatic control systems. MESSER GES., A. May 22,1952 [May 22, 1951No. 13019/62. Class 38 (4). [Also in Group XXII] In means for automatically adjusting the height of a burner by a reversible electric motor the motor is controlled by a touch finger which makes only intermittent contact with the work. In an embodiment a burner 8 is adjustably mounted on a casing which is raised or lowered by a motor 9 driving a rack and pinion 11, 10. A touch finger 6 in the casing which may rest on the work around the burner is raised by an intermittently energized solenoid 5. The lower part of the finger 6 may be of refractory material. Contacts 12, 13, 14, adjustable for sensitivity, are provided in the casing, the contacts 12, 14 forming a switch in the circuit of a solenoid 16 controlling a switch for current supply to rotate the motor 9 in one direction and the contacts 13, 14 similarly operating a solenoid 15 to control rotation of the motor 9 in the opposite direction. The contact 14 is tensioned to engage the contact 12 when the finger 6 is raised but when the finger 6 falls under its own weight or by spring pressure to engage the work at the correct distance a stop 14a holds the contact 14 midway between contacts 12, 13. A motor 1 rotates a cam disc 2 which permits engagement of contacts 3, 3a to energize solenoid 5 during greater part of its rotation and breaks this engagement to make contacts 3a, 4 to allow possible operation of motor 9 during the remainder of its rotation. In operation the burner is set at the correct distance above the work with the finger 6 on the work and contact 14 midway between contacts 12, 13. With cam 2 allowing engagement of contacts 3, 3a solenoid 5 lifts finger 6. On rotation of the cam 2 the solenoid 5 is de-energized, the finger 6 falls and shortly after the contacts 3a, 4 are made. If the burner 8 is at the correct height the stop 14a positions the contact 14 midway between the contacts 12, 13 but if the burner is too high the stop 14a engages the contacts 14, 13 to energize solenoid 15 to make its switch and supply current to motor 9 to lower the burner 8 and casing. If the burner is too low the contacts 12, 14 are made to operate solenoid 16 to effect raising of the burner 8 and casing. The cam disc 2 may be replaced by two or more oppositely rotatable discs. The position of the finger 6 may be transmitted to control means for motor 9 by pneumatic or hydraulic means, by alteration in a capacitance or inductance circuit or by photo-electric means.

[Class 35] [See also Group II] A centrifugal bowl 2 is driven by an electric motor 4, of which the rotor is mounted on the bowl shaft 3 and the stator is steadied by bands 7 attached to the casing by means of pegs 8. The three bands 7 shown in Fig. 2 may be replaced by one continuous band which passes round the pegs 8, or each band may be replaced by a continuous band looped round a lug on the stator. The bands are of elastic material or they may have elastic ends with non-elastic central portions. In the modification shown in Fig. 7, a pair of looped bands 14 are employed, each band passing round the motor and one supporting peg 8. A second pair of bands may be arranged at right angles to the first pair. A number of these supporting bands may be arranged radially between the motor 4 and the casing as shown by the bands 17, Fig. 10. The bands may have eyelets to slip over pins, or have thickened ends to slip into grooves. Frictional material 22, Fig. 12, may be placed between the bands and the motor casing, and the bands may be arranged to engage an element rotatably attached to the motor. The motor casing is extended to form a pivot 21 working in a recess in the supporting frame lined with a frictional element.

Abstract: 1,243,765. Reciprocating pumps. PYE Ltd. March 18, 1970, No.13064/70. Heading F1A. [Also in Division A5] A medical respirator, in which a predetermined quantity of gas is stored at higher than atmospheric pressure in a known volumn during an expiratory period of a respiratory cycle and discharged to a patient in the next inspiratory period, includes a liquid injector for discharging a quantity of liquid stored therein into said quantity of gas, the injector comprising a variable volume container for the liquid, driving means operable by the stored gas pressure to reduce the container volume to discharge liquid therefrom, and a spring 33 having an increasing restitution force with increasing deflection acting on the driving means in a direction to oppose movement thereof caused by the gas whereby the quantity of liquid discharged into said quantity of gas is proportional to the stored gas pressure. The known volume is the maximum of a variable volume V1 defined between a wall 75, rigid diaphragm and flexible surround 73, diaphragm 72 being connected to a smaller diaphragm 70 which together with a surround 71 and wall 74 defines a variable volume V2. During inspiration gas passes from a port 36 via regulator 38 to volume V2 and expels a gas-liquid mixture in volume V1 via valve 40 and flow control 57 to a patient. During expiration gas passes via valve 40 into volume V1 and the gas pressure is applied via a valve 39 to move a bellows 30 connected to a piston to thereby expel liquid from a cylinder 32A via one-way valve D2 to volume V1. Cylinder 32A is connected via a one-way valve D1 to a liquid reservoir, and the movement of bellows 30 and piston 32 is opposed by the spring 33. For a given gas pressure the displacement of piston 32 depends on the location of a movable fulcrum 33B, the position of which may be calibrated in terms of the ratio of gas/liquid supplied to the patient which ratio is substantially independent of gas pressure. Spring 33 may be replaced by a variable effective length leaf spring, bellows 30 by a piston, and diaphrams 70, 72 by a piston with unequal area end-faces. In an alternative embodiment, Fig.2 (not shown), the liquid is injected into the stored gas volume during inspiratory periods.

Abstract: 252,727. Excelsior Feuerl÷schgerõte Akt.-Ges., (Assignees of Paschke, B.). May 28, 1925, [Convention date]. Fire-extinguishing by foam.-A method of producing foam consists in conveying the foam-forming chemicals by gas under pressure to a point near the fire and there introducing them to a stream of water. In the apparatus shown, compressed carbonic acid gas from a bottle c forces the reacting chemicals from separate containers a, b to a mixing chamber g in a nozzle, where they meet a stream of water from a pipe h leading from the main. The gas, which enters the containers near the bottom, serves also to agitate the chemicals. In a modification, the foam generator, for example saponin, is stored in a separate container instead of being mixed with one of the chemicals. In another modification, all the foam chemicals are stored in a common container, and the compressed gas also expels water from a container to the mixing chamber, where it may have an ejector action. The compressed gas bottle may be replaced by an air compressor.
