Title: Improvements in Holding, Lowering and Disengaging Gear for Ships' Boats.
Inventor: ANDERSON ANDREW
IPC: B63B23/18
Filed: 1916-11-10
Abstract: 110,947. Anderson, A. Nov. 10, 1916. Boat raising, lowering, and disengaging gear.-To prevent the falls from fouling and to facilitate the disengagement of the lower blocks from the hooks on the boat, either the upwardly or downwardly running falls or both are led through holes in a guide-block suspended from above. The lower blocks G, have eyes I adapted to be held in engagement with hooks on the boat by the tension of the falls, until such time as the tension is relieved by the boat being water borne when they are automatically released owing to the side pull produced by the guide-blocks J and to the fact that davit heads are spaced closer together than the hooks on the boat. The guide blocks have slots K fitted with rollers R to receive the falls and are suspended in the loop of a line L attached to the bar N connecting the davit heads. The line L may be bifurcated as shown at e, each member passing round pulleys P on the guide, and stops may be fitted to limit the movement of the guideblocks along the line. The guide-blocks may be at right-angles to the position shown in the drawings, and may be coupled together and suspended from above.

Title: Improvements in or relating to conveyor systems
IPC: G03D3/10
Filed: 1925-06-23
Abstract: 258,653. Hepworth, C. M. June 23, 1925. Endless chain elevators with articles hung on hooks; discharging and feeding devices.-In a conveyer system in which a main forward conveyer 14, Fig. 1, has carriers, such as shaped links 21, for the articles at intervals a transverse endless conveyer 25, with carriers for picking the articles off the main conveyer at one point and redepositing them thereon at an advance point, the carriers 28 on the transverse conveyer are such that that portion of the articles actually engaged by these carriers (e.g. rods 23 carrying the articles) are maintained outside the figure swept out by the transverse conveyer when viewed in a direction normal to the plane of such figure. The system is applicable for passing photographic plates or the like through a series of treatment baths, for washing, tanning, curing, and similar operations, or for apparatus involving moving targets or the like. In the construction described the carriers 28 are on the outside of the chain conveyer 25 and comprise curved hooks, having one lip 29 larger than the other 30. Means such as wedge blocks 32 are provided to dislodge the rods 23 from the hooks. The speed of the transverse conveyer 25 may be considerably greater than that of the main conveyer 14.

Title: Improvements in and relating to circuit arrangements employing thermionic valves
IPC: H01J19/82
Filed: 1924-07-05
Abstract: 218,681. British Thomson-Houston Co., Ltd., (Assignees of Compagnie Fran- þaise pour I'Exploitation des ProcÚdÚs Thomson-Houston). July 5, 1923, [Convention date]. Thermionic amplifiers.- Noises due to feeding the filament with alternating current are avoided by making the connections M, N of the grid and plate circuits to points on the filament or on a resistance, transformer or auto-transformer shunting it, such that there is zero alternating plate current due to the filament feed. The Specification deduces that this condition is fulfilled when K = -#/l where K is the amplification coefficient of the valve, and # and l are respectively the distances of the points M, N from the mid-point of the filament, &c. Any remaining noise is eliminated by making the intervalve transformers &c: as efficient as possible for the signal frequency and the reverse for the feed frequency. This may be done by using transformers with an air gap or by using tuned circuits or artificial lines between valves.

A movable fuel element charge machine for servicing a reactor, particularly a pressurized water reactor, whilst it is operating, comprises a pressure jacket 1 which is connected to an opening 23 extending through the reactor pressure vessel, this opening leading to a reactor coolant duct, the machine also including a slide valve 7 for obstructing a passage 11 and a magazine 3 having compartments 18 for receiving fuel elements 6. A cooling system for the machine comprises a pump 9 having its inlet end connected to a helical duct 12 surrounding the jacket 1, the lower end of the duct 12 being connected to the passage 11 at a position above the valve 7. The outlet from the pump is connected to a channel 15 formed coaxially in the magazine 3, this channel 15 being connected to the compartments 18 through channels 17. Surrounding the duct 12 in coaxial spaced relationship is a helical duct 13, a secondary coolant being supplied to the annular space between the ducts 12, 13 and flowing in a downward direction therethrough. Thus when the valve 7 is open a substantial proportion of hot coolant entering the charge machine from the reactor is cooled in the duct 12 before passing to the upper end of the channel 15. In order to further minimize the introduction of hot coolant into the charge machine cold coolant is introduced into the passage 11 at a position beneath the valve 7, this coolant being stored in a container 19 and supplied by a pump 20.
