Abstract: 530,361. Forced-flow steam boilers; heating liquids. PRICE, N. C., and BOEING AIRCRAFT CO. June 22, 1939, No. 18278. [Classes 64 (iii) and 123 (ii)] A boiler arranged within the exhaust pipe 9 of an internal combustion engine and intended particularly for heating or vaporizing a liquid circulating through a heat transfer system as described in Specifications 530,320 and 530,321, [Group VI], consists of a shell 1 with external ribs 11 and a cylindrical core 2 between which and the inner surface of the shell is a helical rib 20 forming a helical path for the liquid, which is led into the upper part of the shell through an axial passage 24 in the core. The liquid inlet tube 4 opens into the lower end of the axial passage and the lower end of the helical path opens into the outlet tube 5. A non-return valve 31 between the inlet and outlet tubes allows the boiler to be drained through the inlet pipe. The base 12 of the shell 1 is secured against a collar 90 on the exhaust pipe 9 by bolts.

Title: Improvements relating to the manufacture of split poles or rods of bamboo or similarmaterial
IPC: B27K3/15
Filed: 1944-09-26
Abstract: Fishing rods, or other poles or shafts, are manufactured by splitting up bamboo, or other wood, applying a heat-hardening liquid resin such as that known under the Registered Trade Mark "Bakelite" to the surfaces of the wooden parts, which have previously been dried, tightly clamping the strips together and then heat-treating them. This is followed by cleaning the surface of each rod thus formed to free it of resin and natural enamel of the bamboo, impregnating the rod with resin by soaking, followed by further heat treatment. Various oven and room temperatures for the repeated heat treatments, are given in the Specification.

Title: Compensation for phase variations on telegraph and telephone transmission lines
IPC: H04H20/67
Filed: 1928-06-27
Abstract: 319,712. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). June 27, 1928. Transmitting sysfems.-Compensntion for phase displacement in currents transmitted on radio broadcasting systems, telegraph picture transmissions, television systems, &c., is effected by subjecting currents of two different carrier frequencies on the transmission lines to a third frequency which is low compared with the carrier frequencies, the low frequency component from each carrier frequency being selected at the distant station and differentially connected in order to indicate the amount of phase displacement produced and required to be corrected during transmission. It is shown in the Specification that for open wire lines, the amount of phase displacement produced with variations of frequency is a linear function. In one arrangement, Fig. 1, frequencies of 10000 and 5000 are transmitted from oscillators 0, O<1>, and a frequency of 250 generated at G is superposed thereon. Currents produced at the three frequencies are subjected to the phase displacement produced on the transmission lines L and at the receiving stations B, the higher frequencies are selected in respective circuits X, Y, the low frequency component of 250 cycles being selected from each of the higher frequencies and fed to oppositely connected transformer windings 10. A balance with normal line conditions is obtained, and the relative phase displacement produced by variations in line characteristics at frequencies of 10000 and 5000 is indicated on the meter 24. A relay 25 operates an alarm 26, and compensating phase adjustments are made on adjusters PA, PA<1> in the circuits X, Y. The adjusters may be mechanically connected or one instrument such as an adjustable condenser may be common to both circuits X, Y. In other arrangements, the separated low frequency components have normally a quadrature relationship and are supplied through thermionic rectifiers to a polarized relay controlling the operation of a reversible motor geared with the phase adjusters.

Abstract: 178,769. Dehn, F. B., (National Pneumatic Co.). July 12, 1921. Controllers, with auxiliary switches. - In traction motor control, in order to prevent current from being turned on when the motors are not protected by the full starting resistance, and when the doors of a car are open, the driver's controller, otherwise of ordinary construction, is furnished with an additional finger 5 and a corresponding short segment in the first resistance position, whereby connection is temporarily made to an electromagnet 12 adapted to close a line switch 20 in series with the trolly 16. The operating circuit of the magnet 12 is taken through switches 14 so that it can only be completed when the doors of the cars are closed. After the controller has passed to the next resistance position, and providing time has been allowed for the electromagnet 12 to work, the magnet remains connected in a hold-on circuit by way of an auxiliary switch 25. A trip switch 13 is adapted to open the circuit when the direction of movement of the controller handle is reversed.

Nozzles for producing whirling and like sprays; commingling jets.-To vary the degree of atomization, liquid is divided in a spraying nozzle into two imping- ing currents or groups of currents, one or both of which may be throttled by a valve or valves. According to the construction shown in Fig. 2, liquid is supplied from the chamber 9 opening into passages 18, 15 leading to a series of tangentially directed orifices 16, Fig. 3, which open into a. whirling chamber 2, Fig. 2, having an injection orifice 1. When the valve 5, Fig. 2, is opened, liquor may also pass from the chamber 9 through passages 8 and 7 to a chamber 11, whence it is forced into the whirling chamber 2 through a series of passages 12 terminating in tangential orifices 14 arranged in opposition to the, orifices 16. When the valve 5 is closed, the fuel entering by the orifices 16 is whirled in the chamber 2, and passes the injection orifice 1 in an atomized condition. By opening the valve 5, this whirling of the liquid can be decreased, and the degree of atomization consequently lessened.

An arrangement for supplying hydraulic fluid through passages 2 in a ship's propeller shaft comprises a non-rotatable sealing ring 8 which provides a connection to the pressure fluid source and is bounded by low-leakage gaps J1, J2, the ring being centred automatically by pressures produced between the adjacent surfaces of the ring and shaft. As shown, pressure chambers 13 are formed between shoulders 14, 15 ; when the ring shifts axially towards one of the walls 5, 6 the pressures in the chambers alter and cause the ring to return to its central position. If desired, only the outer shoulders may be provided or the inner and outer shoulders formed in the same plane; in the latter case, the pressure chambers are connected to the inner face of the ring by grooves or passageways. The pressure chambers may be formed by a series of cavities instead of continuous grooves 13, the cavities being connected to the inner surface of the ring.
