Title: Improvements in governors or apparatus for automatically controlling the speed of engines
IPC: G05D13/00
Filed: 1937-04-22
Abstract: 483,885. Speed governors. SMITH, FULLERTON, Ltd., and SMITH, T. April 22, 1937, No. 11497. [Class 135] A speed governing device comprises a pair of spring-loaded pressure-sensitive members 5, 12 subject to the pressure from a pair of pumps 1, 2 driven by the engine. The piston 5 is directly connected to one end of a floating lever 9 and through linkage mechanism with a throttle valve 7. The other end of the floating lever is linked to the bellows 11. A balanced valve 18 controlling the exhaust from the space below the piston 5 is linked to an intermediate point of the lever 9. The exhaust from the space below the bellows 11 is controlled by a manually actuated throttle 21 arranged in the lower end of the cylinder. An increase of speed causes an increase of pressure below the bellows so raising one end of the lever 9 and increasing the opening of the valve 18. This allows the piston 5 to fall under its spring load and move the throttle valve towards its closed position. As the piston 5 falls it lowers the other end of the lever 9 to restore the valve 18 to the stable position. Adjustment of the hand-actuated throttle varies the control point of the apparatus.

Title: Improvements in safety locks
IPC: E05B55/00
Filed: 1919-05-08
Abstract: 158,286. Imray, O., (Nordqvist, J. H.). May 8, 1919. Night-latches.-The bolt 2, when in the singlelocked position shown in Fig. 4, can be retracted from the inside of the door by the knob 14 and follower 15. From the outside it is actuated by a key turning the barrel 22, Fig. 2, connected by the piece 29 with the plate 8 carrying the pin 6 working in the slot 5. The unlocking movement from the position shown in Fig. 4 is effected by a quarter-turn of the key. By a three-quarter turn. the bolt is first drawn back and afterwards shot forward into the double-locked position shown in Fig. 1. In this position, the bolt is locked out against operation by the knob 14, the pin 3 being in the vertical part of the slot 5. During its movement from the single-locked to the double locked position, the pin 6 acts on the lower end of the hook 12 and draws it down out of contact with the fixed stop 13; in the reverse operation, the hook 12 is restored to the position shown in Fig. 4 in which it abuts against the stop 13 and limits the outward movement of the bolt. The barrel 22, Figs. 2, 6 and 17, contains a number of discs 25 separated by thin partitions 30. A feather 21 in the barrel 22 engages a notch 20 in the fixed cylinder 18 to lock the barrel against rotation. When the key 28, Fig. 16, is inserted and turned, it so arranges the discs that notches 27 are all brought into line with the feather 21. The barrel is then free to turn, the bevelled edge of the notch 20 pressing back the feather 21 into the notches 27. When the feather 21 is thus pressed in, the barrel 22 is no longer locked to the cylinder 18 but is locked to the discs 25 and turns with them. When the key has been given a three-quarter turn the feather 21 moves into the second notch 20<a>, again locking the barrel 22 to the cylinder 18 and leaving the discs free to turn so that the key can be removed.

Title: Improvements in or relating to the manufacture of laminated or multi-ply fused fabrics or articles made therefrom
IPC: D06M17/06
Filed: 1947-05-02
Abstract: An emulsion for coating a fabric contains a polyvinyl acetate emulsion, dibutyl phthalate, formo-gelatine (a reaction product of gelatine and formaldehyde), urea, and water.  After insertion of the coated fabric in a garment, damping with water containing hexamethylenetetramine and tartaric acid, and hot-pressing, a urea-formaldehyde resin is produced when the layers adhere together. Alternatively, the lining fabric may be coated or impregnated with polyvinyl acetate to which is added urea, thiourea, or melamine together with substances which yield formaldehyde on heating such as trioxymethylene, hexamethylene-tetramine, or paraformaldehyde and, if desired, a small amount of formo-gelatine.  In this case resin formation occurs on hot-pressing the fabric with other layers while damped with an aqueous solution of lactic or tartaric acid.

Title: Improvements in and relating to a core structure for a nuclear reactor
Inventor: BOUTIN CLAUDE
IPC: G21C5/08
Filed: 1963-03-27
Abstract: 1,011,338. Moderator structures. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 27, 1963[ March 27, 1962; Feb. 22, 1963], No. 12092/63. Heading G6C. A solid moderator core for a nuclear reactor comprises adjacent columns of solid moderator blocks keyed together and defining between them a series of axially extending channels in which are placed fuel assemblies having provision for circulating coolant therein. The blocks may be regular polygons, giving identical sized fuel channels, or irregular polygons giving substantially smaller regular polygonal fuel channels, and they may be specially shaped to provide circular fuel channels with locating keys in the walls. Also, by varying the crosssections of the blocks, a number of different lattice patterns may be formed. A principle advantage of the invention is that the channels are formed in a solid moderator without large quantities of machining to form hollow moderator blocks. Fig. 3 shows a core formed of regular hexagonal bars keyed on all six faces to adjoining bars; the arrangement also includes a hollow column of blocks 44 for accommodating a control rod. The end faces of adjacent blocks may be arranged at different heights (Fig. 6, not shown). Fig. 10 shows an embodiment utilizing irregular polygonal blocks; this form of arrangement provides greater variations of pitch and lattice pattern than is possible with regular blocks. In the case of irregular polygonal cross-sections in particular, it is preferable to limit the ratios of maximum to minimum section dimension to 3/2, since the blocks are generally machined from extruded bar of circular section. Fig. 14 shows an arrangement of identical blocks for housing a cylindrical fuel assembly 106, and includes keying for rotational alignment of successive assemblies within the channel. Fig. 13, (not shown) illustrates an aligning arrangement for mating the keys in the channel to the keyings in the fuel assembly; the keys are convergently tapered to points, and the keyings are divergently tapered until they merge, giving a true circular section to the assembly end of diameter corresponding to the keying depths. Alternatively, the fuel assemblies may be aligned by providing means to align the lowermost assembly with respect to the channel, and to align successive assemblies with respect to the first. The locked alignment of blocks of a given column may be achieved by engaging the blocks in one another, interposing coupling pieces, or positioning the keys so that adjacent blocks of a column share a common key. In all the assemblies, sufficient space is left between abutting column faces to allow for Wigner growth. Due to these clearances, it is preferable to use sheathed fuel assemblies, and to circulate the coolant within the sheaths, as leakage from the fuel channels would otherwise occur through the clearances provided. Specifications 913,818, 953,298 and 977,019 are referred to.
