Hollow eyelets may be used to secure the reinforcements and bolts passing through the eyelets for securing adjacent beams. Beams having appropriately fluted surfaces may be secured by adhesive. Transversely extending fibrous cement plates 6 may be used as an additional reinforcement. Beams are also of other cross-sectional shape, e.g. closed arc, arc of an ellipse or circle. The Specification as open to inspection under Sect. 91 illustrates and describes fibrous cement sections in many forms, both flanged and otherwise, suitable for providing the framework for beams, rafters, keyposts, tie beams and the like. This subject-matter does not appear in the Specification as accepted.
Patent GB-410300-A (GB)
Title: Improved bearings for crankshafts and the like and method of making the same
IPC: C23C4/08
Filed: 1933-03-21
Abstract: Bearings are made by spraying molten bearing metal on to a base or shell.  The spraying is performed with the use of a spraying pistol of known type which is fed with bearing metal in the form of powder or wire or in molten state.  Prior to coating with the bearing metal the base is cleaned, e.g. by sand blasting, and may then be given a preliminary coating of tin, copper &c. for example, by spraying.  If the bearing material is to be composed of a mixture or alloy of two metals, for example, a leadcopper alloy, a separate pistol may be used for each constituent. Alternatively a single pistol may be used and fed with wires of the different metals, e.g. copper wire with a lead sheath, or separate wires, or wires twisted together, the proportions of the metals being such as to produce the desired alloy. During the spraying process, the base or shell may be heated or kept at atmospheric temperature.  To ensure solidity of the bearing, it may finally be pressed or rolled.

Title: Chemically fueled fluid heater for underwater applications
IPC: F24V30/00
Filed: 1970-02-24
Abstract: 1,267,771. Systems for heating by circulation of fluids heated by exothermic chemical reactions. UNITED AIRCRAFT CORP. 24 Feb., 1970 [24 April, 1969], No. 8856/70. Headings F4U and F4X. A fluid such as water is heated as it is circulated through a passage formed around a heat generating chamber 10 in which a pyrophoric material (e.g. phosphorous) 12 is reacted with oxygen, the heated fluid being thereafter fed to a device requiring heat, such as a vehicle heater or a diver's suit. In the system shown for heating a coil 22 in a diver's suit, water is circulated by a pump 16 electrically operated by a battery 18 which may also provide current for an igniter 20. The heated water from the reactor jacket flows via line 26 to a thermostatic actuator 28 and thence to coil 22 from which it returns via a valve 30 to the heating jacket. Actuator 28 provides that water of uniform temperature enters the coil 22, by recycling (via valve 30 and pressure-relief valve 32) more or less water through by-pass line 34. This results consequently in a change of water flow in the jacket. For example less water flowing through the jacket causes a higher pressure therein, which via line 50 acts on a piston 52 controlling the flow regulating valve in the oxygen supply line 36 and hence (since the reactor chamber is pressurized by an inert gas) controls the reaction. In a modification (Fig. 2) the thermostatic actuator 28 directly controls the oxygen pressure regulating valve 38 so that the regulating means 38 is controlled by the water temperature and not as in Fig. 1 by the pressure in the reactor 10. In other modifications briefly described, the reaction may be operated without the use of an inert gas, the reaction being controlled by regulating oxygen flow and the valve 38 being manually controlled. The igniter 20 may be omitted. The heated water need not be recycled.

Abstract: 472,289. Fluid - actuated valves ; thermally-actuated valves. BARRALET, J. H., and NEW GEYSERS (1931), Ltd. March 25, 1936, No. 8876. [Class 135] A water heater of the kind wherein means comprising a bi - metallic thermosensitive strip are provided to permit the flow of gas to the main burners only so long as the pilot jet is alight and wherein the flow of gas to the main burner is also permitted only so long as water is flowing through the heater has the thermo-sensitive strip arranged when cold to force, by virtue of its own elasticity, the gas valve upon its seating. In the form shown in the Figure, the gas valve 6 is housed in a casing 2 having a gas inlet connection B and an outlet C leading to the main burner. An opening D on the inlet side of the main valve leads to a pilot burner 17, the flame from which is adapted to play on the curved part of a bi-metallic loop 18. One end of this loop is secured to a detachable cover 9 while the other end is bifurcated and is adapted, when cold, to bear on a cap 11 secured to the valve spindle 7 to hold the valve closed. The spindle 7 is suspended by a chain 12 from a two-armed lever 13 carrying a cup receiving water through the water inlet and discharging it through holes in the bottom of the cup. In a modification, the tipping tank is replaced by a floating disc directly connected to the valve spindle. The jet 17 may be replaced by two jets in parallel, one to light the main jets and the other to heat the thermal element.

Title: Improvements in and in connection with Electric Relays.
IPC: B61L1/18
Filed: 1916-06-27
Abstract: 102,793. Sykes' Interlocking Signal Co., W. R., and Tarrant, R. W. June 27, 1916. Electro-magnetic switches and interrupters.-A switch, for controlling the circuit of electricallyoperated railway signals in a track-circuit system employing direct current, is operated by a number of successive impacts delivered, on its return stroke, by a continuously-vibrating armature r carried by a spring s, to a piston k in a cylinder j, whereby air is accumulated in stages in a continually leaking extensible container h, which is finally distended sufficiently to raise the contact member into engagement with the fixed contacts e, f and close the signal circuit. The armature is operated by a self-interrupting electro-magnet m energized by the battery p through the make-andbreak n, o and through the rails a, b. When a train is on the section a, b, the electro-magnet is short-circuited thereby, and the armature consequently remains in its lower position, permitting the piston to fall by gravity or spring-pressure and the container h to collapse, provision being made to permit of a constant leakage from the cylinder. As a result, the signal circuit is broken, and, after the train has left the circuit, the circuit is restored by a succession of upward strokes of the piston of the necessary frequency and amplitude. Stray currents, whether direct or alternating, reduce the frequency or amplitude of the armature, so that the air pressure necessary to maintain the container distended and the signal circuit closed is no longer supplied.
