The Specification describes a braking system generally similar to that of Specification 1,033,118 but modified by the provision in the hand-operated valve 70 of a restricted passage 110 between the inlet 74 and the outlet chamber 99. When the valve rod 72 is depressed by hand to exhaust the trailer reservoir to atmosphere and release the brakes the pressure in chamber 99 holds down the rod until that pressure has fallen sufficiently to allow spring 73 to reset the rod to its normal position. The lower part of the valve exhausts directly to the atmosphere instead of the emergency circuit as in the earlier Specification.

Title: Energy storage and transference by means of liquid heat retention materials
IPC: F01K3/06
Filed: 1975-11-28
Abstract: 1524236 Steam turbine plant EXXON RESEARCH & ENG CO 28 Nov 1975 [16 Dec 1974(2)] 48997/75 Heading FIT [Also in Division F4]  In an electricity generating plant comprising a constant output nuclear reactor or fossil fuel furnace, a boiler and a steam turbine, steam reheating and feed-water pre-heating is effected at part-load operation by bled steam whereas at full load the bleed is reduced and the reheating and  pre-heating effected by heat exchange with a liquid heat storage material at atmospheric pressure. The plant comprises a boiler 1 supplying steam through lines 2, 7 to a high-pressure turbine 6 and thence through reheater 5 to lower pressure turbine 6a. During part-load operation steam bled from turbines 6, 6a through lines 22a, b and 18a, b heats feedwater in line 16 flowing through preheaters 21a, b and 17a, b. In addition some of the bled steam is branched-off through lines 27a, b and 39a, b to heat oil and water respectively flowing in lines 30, 42 through heat exchangers 28a, b and 40a, b. The oil may be additionally heated in heat exchanger 31 by live steam tapped through line 32. The hot oil and water are stored at atmospheric pressure in tanks 34, 43. At full load, pre-heating and reheating by steam is terminated by closing valves 15, 25, 26, 33, 37, 38, 66 and opening valve 50 so all the feedwater passes along line 52 through pre-heaters 53, 55, 59 to be heated by the stored hot water and oil flowing from tanks 43, 34. Some of the hot oil also heats the steam in reheater 5. Thus the plant output is increased without increasing the output of boiler 1. In a modification Fig. 4, (not shown) an additional heat storage stage is provided using a molten salt, sodium or potassium hydroxide or mixtures thereof, or a metal. In another arrangement the heat storage material may be additionally heated by solar energy or waste heat.

In an electric coil comprising a number of series connected conductor turns, to remove forces of attraction between adjacent turns to ensure free passage of cooling fluid through the coil, the conductor is wound in either layers 17, 18, 19 which correspond to tubes of force of the magnetic field of the coil, or in curved discs (32), (Fig. 7, not shown), which correspond to equipotential surfaces of the field. In the former case all forces on the conductor are normal to the surfaces of the coil layers and these forces are resisted by curved supports 21, 22, 23 mounted on columns 24 while in the latter case the forces are tangential to the disc surfaces and are resisted by rings (35) mounted on supports (37). In either embodiment, to vary current density within the coil, the extremities of the coil may have spacers between adjacent turns, or alternatively the cross-sectional area of the conductor may be varied.

A gas stream is fed upwards through inlet 2 into a cylindrical space defined by the vertical, circumferentially spaced, radially inner edges of the blades 3, which are arranged in several layers as shown, each blade extending outwards form the space initially along an involute curve and finally straight and radially, the blades in each layer being curved in the opposite direction to those in the next (Fig. 2 not shown). The interference between individual streams of gas flowing outwards between the blades in adjacent layers causes additional rotation of the gas streams about their general directions of flow, which throws the entrained droplets centrifugally onto the blades. The droplets are carried along the blades to the outer part of the blade stack, where the reduced gas velocity allows them to flow down to outlet 7. The upper and lower blades are half the height of the blades in, the central layers, because the streams flowing between central blades are each split into upper and lower contra-rotating sections by the interference of adjacent streams above and below. The blade spacing at the inner ends corresponds to the heights of the upper and lower blades. Cone 5 distributes incoming gas among the blades. Gas inlet 2 and outlet 6 are coaxial of the housing 1.

Abstract: 1308345 Slide projectors AMERICAN OPTICAL CORP 2 Nov 1970 [31 Oct 1969 52090/70 Heading G2A A slide projector includes rotatable members 12, 14, 16 each having apertures around its periphery to receive slides and the member 12 has a slide holder which is rotatable about the axis of the aperture at which it is located. Each member 12, 14, 16 is rotatable between specific positions whether adjacent to each other or not. The projector includes a lamp 4, condensing lenses 6 and objective lenses 5. Gears 40, 42, 50, 58 which mesh directly with the shaft of four respective motors (60), (62), (64), (66), Fig. 2 and 9 (not shown), rotate the slide holder rotating mechanism on the member 12 and the members 12, 16, 14 respectively. The member 14 is fixed to the shaft 10 whilst the other members and gears 40, 42, 50 rotate freely thereon. The rotation of the members 12, 14, 16 and slide holder is controlled by circuiting, Fig.9 (not shown), it being possible to rotate both the members and holder in either direction, together or separately. Initial movement is caused by the closing of one or more of a set of switches (72A), (72B), (72C), (72D), or (73A), (73B), (73C), (73D) depending on the direction required. If the switches are allowed to return to their normal positions, as shown in Fig. 9, the movement of the members 12, 14, 16 will continue due to energization of one of a set of relays (82), (84), (86) which ceases when the nearest of the specific positions on the members are reached. This is because one or more switches (68) open as their contacts fall into notches on the members. The motor (60) driving the holder incorporates no relay into circuiting and stops immediately either of its associated switches (72D), (73D) opens.
