Abstract: 573,078. Bombs etc.; torpedoes. BATH & PORTLAND STONE FIRMS, Ltd., and PICTOR, A. N. Oct. 5, 1942, Nos. 13974 and 17969. [Classes 9 (i) and 9 (ii)] A hollow-charge bomb, grenade or the like, or torpedo has the hollow at the front end of the charge formed as a concavity, as distinct from the conical cavity described in Specification 280,030/11, [Class 9 (ii)], and the cavity has a lining 2 of a material of low melting-point, e.g. of a plastic such as " Perspex " or " Bakelite " (Registered Trade Marks). The missile has a base fuze 11 which may be of the momentum type or a direct-impact fuze fired by an axial rod extending from the nose through the charge 8. The burst is effected before the charge can make contact with the surface attacked by the provision of a collapsable ballistic head 3 of suitable length or by a rod or like distance-piece. The cavity may be empty or may contain various bodies including incendiary material. As shown, it contains a so-called " pellet " 9 of cup-shape. The pellet, if of steel, has a coating of ferro-cyanide at the forward portions 10; the blast closes up the pellet, as shown at 10<1>, and hardens the pointed end to facilitate penetration. -A solid pellet may be used. In a further modification, the nose 3 may be of armour-piercing steel which may be combined with an incendiary filling. The casing 1 may also be of a plastic, in which case its thickness is increased. Specification 561,927 also is referred to.

Title: Elevator safety appliances
IPC: B66B5/22
Filed: 1925-06-02
Abstract: 236,905. Waygood-Otis, Ltd., (Assignees of Lindquist, D. L.). July 11, 1924, [Convention date]. Safety retaining mechanism. -A brake on the cage is applied to a stationary guide rail in case of excessive speed, insufficient retardation on approaching terminal points, and over-travel. The brake comprises a pair of shoes 69 which are supported by links 70 pivoted to jaw members 61, 62. Springs 79 are placed between the shoes and jaw members. The jaw members are connected by pivots 64 to fixed members 58 attached to a beam 21 secured to the cage bottom. Springs 67 are placed between the members 61, 62 and 58. The brake shoes are actuated by rods 60 which are urged downwards by springs 96 and rest on cams 98 mounted on shafts 99. The shafts 99 are geared together and one f them is geared to a shaft 104 provided with an arm 108 to which is connected one end of a rope 38. The .other end of the rope is attached to a hitch 26 on an endless rope 25 which is held normally in a releasing carrier 27 on the cage. The rope 25 passes over a sheave driving a centrifugal governor and between pivoted jaws 28, 29. An arm 31 on the jaw 28 is engaged by a spring-pressed catch 33 and connected to the governor by a link 32. When the cage overspeeds, the governor closes the jaws on the rope 25 and stops its movement. As the cage continues to move, the hitch 26 is withdrawn from the carrier 27 and the shaft 104 is rot'ated, thereby causing the application of the shoes 69 to the guide 16. When the shaft 104 has been turned through an angle of 90‹, the rope 38 draws the rope 25 through the jaws 28, 29 as the latter jaw can move horizontally against the resistance of the spring 37. The brake is applied automatically if the speed is not reduced sufficiently on approaching the landing 42 by a governor-controlled cam 41 projected into the path of a lever 112 mounted on the cage. A link 110 connects the lever 112 and arm 108. The cam 41 is secured to a rod 43 slidably mounted in supports 44 and connected by a toggle linkage 45 to an abutment 46. A link 47 connects the toggle with a lever 48 actuated by a governor 23. An endless rope 39 attached to the cage drives the governor. The cam remains in the path of the lever 112 if the speed is insufficient'ly reduced. Spring catches 49, 50 on the link 47 co-operate with latches 51, 52 respectively on a stationary support. If the car over-travels the landing 42, the brakes are applied by the engagement of the lever 112 with a cam 24 mounted in the well. The cam is pivoted so that it will be turned out of the path of the roller 116 on the lever 112 as the cage rises. The guide rail 16 is increased in thickness above the point 19 so as to apply the brakes if the cage overtravels on the upward run. In order that the slippers 85 of the guides 17, 18 shall always engage the rail 16, they are carried by slidable rods and are acted on by springs 89. A similarlymounted plate 90 is applied by springs 92 to a third face of the rail.

Filed: 1962-04-13
Abstract: 963,161. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. March 28, 1963 [April 13, 1962], No. 14349/62. Heading G6C. In a nuclear reactor the moderator comprises an equilibrium mixture of a solid acceptor material containing a moderator and the same moderator in a fluid phase, the reactor being adapted for variation of the equilibrium conditions so as to vary the moderator content of the acceptor material. The moderator is preferably a metallic hydride, e. g. titanium or zirconium hydride, in contact with gaseous hydrogen, but deuterides might be used as an alternative. In the reactor shown the fuel elements 19 are disposed in pressure tubes 18 and are cooled by pressurised heavy waters. A titanium hydride moderator 21 surrounds the tubes and is in contact with a toroidal chamber 22 through an apertured wall. The chamber 22 is filled with a gaseous mixture of hydrogen and an inert carrier gas and the pressure of the mixture can be varied, thus varying the hydrogen content of the moderator 21. As fuel burns up in the reactor the average coolant temperature drops due to reduced reactivity, and at intervals the average temperature is raised by increasing the hydrogen pressure to cause greater moderation within the reactor.

Abstract: 1,188,821. Coffee machine. VENDO CO. 22 April, 1967 [22 April, 1966], No. 14424/67. Heading A4D. A coffee brewing and dispensing apparatus comprises an upright brewing cylinder 34 having an open top 76; a reciprocable piston 36 in said cylinder having a brewed coffee passage 72 therethrough adapted for communication with a delivery conduit 74; a filter 64 on said piston overlying said passage 72; means 182 for delivering hot water and means 176 for delivering coffee from container 180 through opening 184 into the cylinder's open top; a scraper member 108 normally positioned adjacent the top of the cylinder and movable along a path of travel in scraping disposition thereto; closure means 38 associated with said cylinder for closing said open top thereof; and drive means operably associated with said member 108, the piston and said closure means, which drive means consists of an electric motor 28 connected to a rotatable output shaft 46 on which are coupled two cams which effect reciprocation of cylinder 34 and swinging of lid 38 and wiper 108, and a crank means 50 intercoupling said shaft and said piston for reciprocating the latter. In operation motor 28 is energized and a predetermined quantity of hot water is discharged from tube 182 into brewing cylinder 34 simultaneously with the delivery of ground coffee via auger 176. At this stage cylinder 34 is at the lower limit of its path of travel, piston 36 has begun a downstroke (Fig. 3, not shown), wiper 108 is retracted with the lid 38 clear of the cylinder and filter 64 is disposed below top 76. The lid 38 now approaches a position directly above open top 76 of the cylinder and cylinder 34 shifts upwardly to seal the top (Fig. 12, not shown). When seal is effected piston 36 commences its upstroke and causes the brew to be forced through filter 64 along passage 72 to conduit 74 for discharge into the cup. During this operation air is trapped between the brew and the underside of lid 38 such air being compressed by the piston on its upstroke. After coffee has been forced out of the cylinder this compressed air follows and expands through filter 64, which air dries the grounds and purges conduit 74 as well as discharging fine coffee residue in the filter openings. Lid 38 now swings towards its standing position, at the same time cylinder 34 moves downwards to clear bottom of said lid until the upper surface of filter 64 and upper surface of platform 78 are flush with one another. Scraper 108 now scrapes the upper surface of filter 64 (Fig. 13, not shown), which filter is suitably composed of an inert flexible synthetic resin substance.
