Abstract: 939,063. Dynamo-electric machines &c. L. R. POWER CORPORATION. Oct. 28, 1959 [Oct. 28, 1958], No. 27371/63. Divided out of 939,061. Class 35. In a machine with rotatable permanent or electromagnetic pole members and a stationary armature winding, this winding is secured by clamping rings. In the planar-air-gap, permanent-magnet machine shown, a moulded winding disc 8 is secured by clamping rings 63, 64, 65, 66 between rotating pole-members 6, 7. Various forms of stator coil are described (Figs. 9-15, not shown) and the winding disc 8 as a whole is axially adjustable by means of studs 70 passing between the end-covers. The fixing rings may have lugs projecting into the coilwindows so that the winding disc 8 may be radially tensioned (Figs. 18-25, not shown). Adjustment of the machine performance may be achieved by rotating, i.e. staggering, one of the field members with respect to the other, e.g. by the selective engagement of slots by key 78. The stator windings may include iron inserts, and eddy-current losses in the conductors are reduced by forming them of ribbons lying on edge to the flux. Instead of being planar the air-gap may be cylindrical or conical. Various arrangements of winding are described.

Title: Improved door control mechanism
Inventor: HALLETT HERBERT RICHARD
IPC: E05B65/38
Filed: 1959-08-12
Abstract: 884,403. Door operating appliances; remotely controlled fastenings. MANGANESE BRONZE & BRASS CO. Ltd. Aug. 10, 1960 [Aug. 12, 1959], No. 27518/59. Classes 44 and 65(1). A pair of doors diagrammatically represented by chain lines are locked by pneumatically operated bolts 9 which are actuated when the doors engage projections from the control valves 8 on closing. The main reservoir 2 is connected via a pressure reducing valve 3 to a reservoir R in which the pressure is maintained nearly constant (say 70 1bs./sq. inch); the emergency valve 4, one of which is located externally on each side of the vehicle carrying the door operating system, normally connects the reservoir R with the electro-pneumatic switch 5 which when closed supplies air to the pressure reducing valve 6 whereby the double acting cylinders 1 are operated at a reduced pressure (say 25 1bs. /sq. inch) to close the doors. The valves 8, opened when the doors are fully closed are connected in series to the switch 5 at a point before the valve 6; the locks 9 are connected in parallel and are both operated when both doors are closed; also connected in parallel with the locks 9 is a device 10 which may automatically apply brakes until the doors are closed or may control a "doors closed" indicator. When switch 5 is opened the locking system is exhausted to the atmosphere, unlocking the doors, and when the pressure is low enough exhausting the cylinder 1 through the one way valve 7. Simultaneously the switch 5 supplies high pressure air (say 70 1bs./sq. inch) to the centre of the cylinder 1, through the valve 11, to open the doors. In an emergency, operation of the valve 4 exhausts the door locking system and supplies high pressure air to the centre of the cylinders 1 via the valve 11, thus unlocking and opening the doors independently of the switch 5.

Title: Method and apparatus for obtaining average samples of liquids for testing purposes
Inventor: RAMSAY DOROTHY AGNES
IPC: G01N1/12
Filed: 1958-08-29
Abstract: 863,592. Sampling liquids. FRANK RAMSAY Ltd. Aug. 28, 1959 [Aug. 29, 1958], No. 27745/58. Class 106(5) A method of obtaining average samples of liquid comprises gradually immersing a collecting apparatus into the liquid, such as petrol, oil, beer or milk, dividing the liquid entering the apparatus into two streams, the rate of increase of volume of one of the streams with respect to the depth of immersion being a predetermined function of the depth and the latter stream being trapped within the apparatus at some desired depth. The apparatus comprises an outer cylindrical vessel 1 closed at the top and open at its lower end and having therein a funnelshaped inner vessel 7 located centrally by spiders 6 and arranged with a small clearance 10; a hinged flap valve 8 is provided in the lower end of the vessel 7 which latter end is arranged to coincide with the open end of the vessel 1. In operation, the apparatus is lowered such as by a rope 3 slowly into a tank containing the liquid and, due to the pressure of the liquid, the valve 8 is opened and thereby allows liquid to enter both the inner and outer vessels 1, 7. As the liquid rises in both vessels, the air in the space B of the outer vessel is compressed and since this pressure is dependent upon the depth of immersion of the apparatus, the inner vessel is so shaped as to permit a constant volumetric increment to enter therein proprotional to each increment of immersion. When the apparatus reaches the desired depth determined by a weight 5, attached to legs 4, touching the bottom of the tank, the apparatus is raised together with the sample of liquid trapped in the inner vessel 7. In the construction shown in Fig. 2, the top end of the inner vessel 7 is located adjacent the closed end of the outer vessel 1, grooves 11, 12 being provided to allow the air to pass through a flexible pipe 15 into a container 17. A spring- loaded valve 18 is provided in the bottom of the inner vessel 7 which, before the apparatus is lowered into the liquid, is retained in its open position by a spring-loaded pawl 26 engaging an abutment 25 on the valve rod 19. The valve is closed when the apparatus reaches the bottom of the tank by an abutment 30 on the valve rod 31 engaging a cam surface 29 of the pawl. Upon removal of the apparatus from the liquid, the sample may be withdrawn from the vessel 7 through a spring-loaded valve 34.

Abstract: 1421620 Inertial navigation system FERRANTI Ltd 11 June 1974 [12 June 1973] 27989/73 Heading G1C In an inertial navigation apparatus, the heading alignment of an inertial platform carried by a vechicle 14, e.g. ship-based aircraft is checked and corrected by means of a base station 10, e.g. the ship, which has equipment for determining the orientation α of a datum line 11 relative to a fixed reference direction, e.g. true north. The vehicle 14 carries a sighting mark and the base-station 10 a mirror 12 in which the sighting mark is visible to an observer in the vehicle 14 when the vehicle 14 is located on a base line 13 defined by the mirror 12. An aiming mark is carried on the vehicle and is movable 80 as to be aligned with the image of the sighting mark in the mirror 12, the aiming marks generating a signal indicative of its position relative to the vehicle axis 15 i.e. dependent upon angle γ. A navigation computor responds to the signals indicative of angle γ, to the angle between axes 11 and 13 which may be zero in the Fig. 1 embodiment, or # in the Fig. 3 embodiment, and angle α. Thus the heading alignment # of the  vehicle inertial platform may be checked and corrected since if correct α = # - γ (Fig. 1) or α = # + γ - α (Fig. 3). The computer sends a correction signal to the platform if the equality is absent. The mirror may be a corner reflector.

Abstract: 373,902. Feeding webs. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (American Machine and Foundry Co. ; 511, 5th Avenue, New York, U.S.A.) Oct. 9, 1931, No. 28067. [Class 100 (i).] A device for controlling the wrapper feed of a wrapping machine comprises means for stopping the feed in the absence of an article to be wrapped. The paper is fed from a reel R under an idle roller 8 and between continuously rotating feed rolls 10, 11 and thence to intermittently driven rollers 13, 14 above a guide 15, 18. The roller 14 is mounted on an arm 37 with an extension 38, carrying a roller 39 which engages a cam 40 under the action of a spring 42. The cam normally holds the roller 14 out of engagement with the roller 13 and no feed takes place, but, during the time that a flat 41 on the cam passes the roller 39, the spring 42 pulls the roller 14 into engagement and a length of material is fed from a loop L which has accumulated owing to the continued rotation of the rollers 10, 11. The shaft 23 carrying the roller 10 is driven from the main drive by a chain 21, and the roller is normally rotated with the shaft owing to the engagement of a pawl 25 with a notch in a disc 27 on the shaft 23. If, however, no article is present in the package runway 20, a feeler 44 falls from the position shown in broken lines to that shown in full lines, and causes, through links 46, 47, an arm 51 to trip the end 52 of the pawl 25, thus stopping the wrapper feed. When the feeler 44 is next moved into the raised position, the pawl reengages and the feed is resumed.
