In a lock of the type in which pivoted security levers require to be lifted by respective correct amounts in order to release the bolt for direct or indirect operation by the key each lever is lifted by a key-operated member which is guided for substantially rectilinear movement and when operated by a step of any particular key imparts the same lift to its associated lever irrespective of the direction in which the key is turned. In the lock of Fig. 1 the bolt 11 is withdrawn by turning a key such that each lever 17 is raised by a vertically moving guided member 19 the apex of which engages and raises the underside 23 of the lever. Actuation by a servant key aligns a notch 25 in the lever with a nosepiece 27 on a spring-loaded bell-crank lever 28 so allowing the bolt to be withdrawn by abutment of the rotating key against a surface 15 of the bolt and in doing so swing the nose into the notch through the interengagement of protuberances 30, 31. Actuation by a master key aligns a notch 26 in the lever 17 with the nose-piece 27. In the lock of Fig. 2 the member 19 lifts the lever 17 through inter-engagement of surfaces 35, 36 the levers 17 and 28 being respectively vertically and horizontally disposed. In the lock of Fig. 3 not shown) the lever 28 is below the bolt whilst the upper part of the member 19 abuts the rear end of the lever 17 which is horizontal and fulcrumed intermediate its ends. Fig. 4 (not shown) illustrates a lock in which the bolt is moved by a member intermediate the key and bolt whilst in yet another lock the member 19 is constrained to move in a guide 45, Fig. 7, and the bolt 11 is slidably actuated through the intermediary of a slidable member 43 and a pivoted bracket 42. Figs. 8 and 9 (not shown) illustrate locks in which the member 19 is constrained for vertical movement by arrangements respectively comprising one and two guide checks. A lock construction is described without a master and servant key arrangement the lever 17, Fig. 5, comprising a H-gate co-operating with a member 42 attached to the bolt.

Title: Improvements in and relating to cyanuric acid
IPC: B01J6/00
Filed: 1959-06-03
Abstract: In a process for the pyrolysis of urea at 230-375 DEG C. into crude cyanuric acid, the urea is fed to the heating zone as a free-flowing granular blend <PICT:0890814/III/1> of crude cyanuric acid and urea containing not more than 35 parts wt. urea from a mixing zone.  The granular blend should be 1/16 -\ba1/2 inch particle size containing 5-35% urea. The blend may be prepared by spraying molten, or aqueous, urea on to the hot product of the process, and in the former case the heat of the product causes partial pyrolysis, while in the latter water evaporation.  Blending is effected in a pug mill, or sigma, or ribbon, blender.  Alternatively, crystalline urea is mixed with cold product.  Heating may be 6-40 mins. in a fluidized bed, Herreschoff furnace, pug mill, or ribbon, or screw blender. Granular feed passes from hopper 18 through screw feed 16 to inclined rotary kiln 10 provided with scraper 24 at the feed end. Product passes over damn 28, and 11-20% is withdrawn as product through 32, while the remainder is collected in blender 34, where it is sprayed with aqueous urea from 36 through 40.  The resulting blend is returned to hopper 18.  The aqueous urea is increased in strength by urea condensed from the exhaust gases.  The kiln exhaust gases pass from hood 29, through pipe 30, maintained at 220 DEG C. to prevent condensation, to urea recovery system 50.  The urea recovery system may be a condenser with walls maintained at 115-130 DEG C. by a hot oil jacket from which liquid urea is returned to the system, or may be a Raschig ring packed scrubbing tower irrigated with aqueous urea and jacketed with hot water or steam. The crude product is treated with strong mineral acid, e.g. HCl or H2SO4, at the boiling point or under pressure to hydrolyse ammeline and ammelide to cyanuric acid and washed to yield pure acid.  Specification 877,725 is referred to.

Title: Improvements in lubricant-distributing systems
Inventor: LECLAIR CAMILLE CLARE SPRANKLI
IPC: F16N13/16
Filed: 1951-08-10
Abstract: 720,175. Lubricating. TECALEMIT, Ltd. July 17, 1952 [Aug. 10, 1951], No. 18914/51. Class 12 (3). A grease-injector or oil-injector comprises a grease-discharge cylinder 6, Fig. 1, fitted with a piston 9 connected to a compressedair-operated piston 3 slidable in a cylinder 2 which is connected by a passage 44 to a cylinder 13 of a compressed-air-operated piston 11 connected to a control valve 12 the arrangement being such that when the control valve is in one operation position grease is fed at constant pressure into the grease discharge cylinder 6 and when the valve is in its second operative position, the grease is discharged from the cylinder 6 to a bearing or other place of use. The control valve is provided with two parts 39, 40 separated by a part 41 of reduced diameter, and is slidable in a liner 16 formed with horizontal passages. A spring 51 is located between the piston 11 and the liner 16. When compressed air is admitted to passage 44 the piston 11 is pressed down to the position shown and pressure is exerted on the piston 9 so that lubricant in cylinder 6 is forced out through openings 31, 30, 29, 28, 42, 32 and 33 to an outlet 34 which is screw-threaded for connection to a pipe leading to a bearing or other point for lubrication. When the compressed air is cut off and vented to atmosphere, the spring 51 raises the piston 11 and the control valve 12, and lubricant under pressure is then supplied to the cylinder 6 through openings 23, 17, 42, 18, 28, 29, 30 and 31. The stroke of the piston 9 may be adjusted by means of an axially-adjustable screw 47 provided with a lock nut 49. In a modification the piston 3 is provided with a spring-pressed valve which is opened when the piston 3 reaches its lowest point and the compressed air in passage 44 is then vented to atmosphere. In the construction shown in Fig. 5, the piston 3a is provided with a rod 52 carrying an adjustable 'collar 54 by means of which the stroke of the piston 3a can be varied. As the rod reciprocates with the piston 3a, the collar 54 and a shoulder 64 on the rod 52 alternately engage an arm 62 carrying an abutment 63, whereby one or other of two pairs of contacts 60 and 61 are closed to short-circuit electromagnets that are normally energized. Failure of the piston 3a to complete its charge or discharge stroke results in one of the electromagnets remaining energized, and this may be indicated by a visual or audible warning. In a further construction, for use in an arrangement in which more than one injector is used, the adjustment rod and collar associated with the grease discharge piston is adapted as it reciprocates to operate a counter mechanism, whereby the injector may be compared with other injectors similarly equipped.

A three-element epicyclic gear train having a sun gear 21, planet gears 18 on a carrier 17 and a ring gear 20 has two elements connected respectively to the input 10 and output 14 shafts and the third element connectable by an axially moving clutch member 24 to one of the shafts to provide direct drive and to a non- rotating member 31 to provide a ratio drive, the clutch member being biased in one drive direction and moved by fluid pressure-operated means against the bias means 28 for the other direction for drive in the other ratio, the return of the clutch member by the bias means being baulked by fluid exhausting through a restrictor 47 to delay engagement. In an overdrive unit, direct drive is provided by the engagement of clutch member 24, splined to sun gear 21, with ring gear 20 integral with the output shaft 14 under the bias of springs 28 acting through a radial flange 29. The admisison of fluid pressure from valve 36 to space 38 urges an annular piston 31 to brake the clutch member 24 and release it from ring gear 20 to engage overdrive. At the same time pressure passes through a passage 43 to move an annular piston 40 which contacts the flange 29. On release of pressure springs 35 retract the brake piston 31 to disengage overdrive and a one-way restricting valve 45 moves to the right to restrict release of pressure from the piston 40 and delay re-engagement of direct drive ratio. By interchange of the connections to the epicyclic train the gearing may provide underdrive or forward-reverse with delay baulk in one engagement.
