Abstract: 106,845. Stirling, J. H. May 25, 1916. Feed-water, heat. ing. - Feed-water heating and purifying apparatus, com. prising open ves. sels or trays mounted in the boiler steam space, is provided with means for cleaning the vessels without removing them from the boiler. Access to the tray a, Figs. 1 and 3, extending across the top of a locomotive boiler is afforded by tubular pieces u secured to the boiler shell opposite apertures in the sides of the tray. The outer ends of the tubular pieces are closed by screwed caps v. The water flows through perforated chambers h and overflows into the tray through side apertures o fitted with flap or like valves p. The water flows from the tray through pipes q having upturned ends. The baffles 6, Fig. 7, in open vessels a mounted in the boiler on both sides of the steam-pipe, are cleaned by rakes inserted through hand-holes in the top of the boiler shell. To reciprocate a scraper 25 placed permanently in the tray 22, the rod 29 on the scraper projects into a sleeve in the side of the boiler, so that when the screwed plug 32 in the sleeve is removed, a handle may be screwed on the end of the rod.

In a small volume liquid break switch the arc chamber 6 contains a liquid, e.g. oil, permanently under pressure and a movable contact 9 is movable to the closed position by applying the chamber pressure to the other side of a differential piston 18. The chamber 6 is connected to a pump 3 by way of an accumulator 4; a cylinder space 19 can also be connected by a valve 5 so as to apply chamber pressure to the piston; the other side of the piston extends into the arc chamber and thus always experiences the pressure. To open the contacts valve member 5a is rotated so as to connect space 19 with a low pressure reservoir 12 surrounding the arc chamber 6. In modifications (Figs. 2, 3, not shown) valves are fitted to permit release of excess pressures produced in the arc chamber due to arcing.

[Class 126] The side walls of the oil container 10 of a wick lamp used in a refrigerating apparatus are fitted with rollers 16, 17 engaging horizontal rails 18 on the refrigerating cabinet, the rollers 17 at the burner end of the container being higher than the rollers 16 so that during the insertion of the lamp the container is inclined downwardly and the upper part of the glass flame protector 12 clears the mouth of the flue tube 25. The ends 20, 19 of the upper limbs of the rails 18 are inclined upwardly to facilitate insertion and to allow the burner end of the container to rise by gravity as the lamp approaches its operative position until a hood 28 closely surrounding the upper part of the flame protector engages a stop pin 27 on the flue tube flange 26. The lamp is then guided by the engagement of the pin 27 with a V-rail 30 on the head 28 until the pin 27 registers with a hole 29 in the head 28 and locks the lamp in position. A metal ring 14 at the top of the flame protector 12 forms a throttle member for the burner in place of the contraction usually provided in glass lamp chimneys.

Class 40(1) [Also in Groups XIX and XL(c)] In an arrangement for adding binary numbers (see Group XIX) a voltage is built up from a number of simultaneously occurring unit pulses and then translated into a binary seriesmode pulse train. The voltage to be translated is applied through a lead 10. Fig. 1, to five separate amplitudediscriminator circuits ADCI ... 5 initially adjusted to respond to pulses of (i) one unit amplitude or over, (ii) two units amplitude or over, (iii) four units amplitude or over. (iv) eight units amplitude or over, and (v) sixteen units amplitude or over. respectively. (The actual amplitude levels are ¢: 1¢, 3¢, 7¢ and 15¢). Each discriminator ADC2 ... 5 tests the amplitude of the input voltage and if respondent, sends back through an appropriate delay device DC1 ... 4 a pulse equivalent to the value represented by the discriminator (i.e. 2 = 10, 4 = 100, 8 = 1000, or 16 = 10000), and also causes the discrimination levels of the lowervalue discriminators to be increased by the same amount (see Group XL(c)). The representation of the magnitude of the input voltage in the form of a binary series mode pulse train, emerges from the output of the lowest-value discriminator ADC1.

Title: Process for the preparation of linear organopolysiloxanes
Inventor: LEFORT MARCEL
IPC: C08G77/06
Filed: 1966-03-11
Abstract: Linear siloxane oils or gums are made by contacting a cyclic or oligomeric siloxane with a diorganosilylsulphate, generally at 20 DEG to 150 DEG  C. and optionally in the presence of a chain limiter. The products can be represented by the formula <FORM:1073325/C3/1> , in which each R is H or a monovalent saturated or unsaturated, substituted or unsubstituted hydrocarbon radical, R1 is R, -OH or -HSO4, and n has a value from 100 to 8500, there being not more than 2 H atoms on each terminal Si atom, and less than 10% of the R radicals being H and/or unsaturated radicals. The silylsulphate may be used in amounts of 0.05 to 5.0% by weight expressed as SO4- - based on the total siloxanes used.  If desired, the product containing SO4- - ions can be neutralized by mixing it with Al2O3, MgO, ZnO or (NH4)2CO3 and volatiles can then be removed by kneading it under a current of nitrogen at 100 DEG  to 200 DEG  C. Examples are given.

Title: Infrared laser
IPC: H01S3/223
Filed: 1971-04-23
Abstract: 1312411 Lasers INTERNATIONAL BUSINESS MACHINES CORP 23 April 1971 [30 April 1970] 10904/71 Heading H1C An infra-red gas laser active medium comprises a mixture of hydrogen, helium and a polyatomic gas, where the latter is chosen to have a resonant energy level close to the first metastable state of hydrogen and to have allowed transitions from that resonant level to the ground state, so that when the mixture is excited by a discharge the hydrogen is raised to its first metastable level and this induces laser emission by vibrational excitation of the polyatomic gas. Suitable polyatomie gases are acetylene, methane, ammonia or ethylene, the first being preferred. The helium provides a mixture of suitable pressure and composition for the establishment of an electron energy distribution favourable to excitation of the hydrogen. With acetylene, preferred partial pressures of H 2  : C 2 H 2  : He are 2-4 : 1-2: 10-20 torr, and the mixture is surrounded by a cooling jacket at 200-300 C. Apparatus.-Fig. 1 shows a discharge tube 10 through which the gas mixture is flowed. The tube is surrounded by a cooling jacket 11, and has a resonator mirror adjustably supported at each end by steel bellows 8, 9. The mixture pressure may be read at 53. A pulse source 20 is connected to electrodes 16 and 17, and an outline circuit for a D.C. pulse source is given, Fig. 2 (not shown). Alternatively A.C., D.C. or R.F. excitation may be used; pulsed sources are preferred, and the pulse energy must be enough to vibrationally excite the gas without dissociating it. Allowable transitions for the various polyatomic gases, and the outputs produced, the majority of which are below 10 Á, are given in Tables 1-4 and Figs. 3, 5 and 6 (not shown).

April 12, 1933, No. 10974. [Class 38 (iii).] Field control.-In a control system for a compound-wound motor in which resistance is first cut out of the armature circuit, and then resistance is inserted in the shunt field circuit, means are provided whereby resistance is inserted in the shunt field circuit during the armature circuit control, and removed before the shunt field control is effected. Movement of master controller MC causes successive closure of contacts 17-21, and then successive opening of contacts 22-28, the one set of contacts controlling contactors 1, 1A, 2 .. 5, whereby the motor is connected to the supply, and armature resistance cut out in steps, and the other set of contacts controlling contactors 6-12 whereby shunt field resistance is inserted in steps, and the shunt field circuit finally opened. The circuit of the contactor 6, controlled by the contact 22 of the master controller, is also controlled by the contact 20, so that the shunt field resistance section controlled by the contactor 6 is in circuit until the fourth controller notch is reached, whereupon it is excluded and reincluded on the sixth notch. Thus the shunt field is not at full strength until the fourth notch. Interlock contacts 1a, 4a, 5a, on the main and resistance contactors 1, 4, and 5, ensure the exclusion of armature resistance during complete return movement of the controller to the " off " position.

The plate 40 has a slot 58 coextensive with one keyway, and a screwed rod 62 passes through a tapped post 60 secured to a key. Manual rotation of a knob 64 moves the frame and spray head parallel to the upper slope of the knurled surface of the feed roller 34 and thereby alters the position of the wire on that surface to vary its speed through the gun.
