Title: Improvements in Support Systems in Steam Generators
IPC: F22B37/24
Filed: 1968-06-12
Abstract: 1,173,266. Supporting steam generators. MONT INTERNATIONAL ASSOCIATION Ltd., and H. VORKAUF. 12 June, 1968 [1 Dec., 1967], No. 27893/68. Heading F4A. In a steam generator, e.g. of the forced circulation type, the steam generating heating surfaces are supported from an overhead structure comprising longitudinal steel beams 1 resting on transverse steel beams 2 supported on two or more vertical steam and water drums 3 containing fluid at the same temperature and pressure as that flowing internally through tubular elements forming the steam generating heating surfaces. Thus the downward expansion of e.g. the vertical water-cooled combustion chamber 5 is compensated by the upward expansion of the drums 3 so that the point O, e.g., is maintained at a relatively constant vertical position whereby specially designed connections to the generator at this point, e.g. connections for the burners and air supply, are avoided. To permit expansion in the horizontal direction, one drum is fixed and the other is flexibly mounted and supports the beams 2 via a flexible mounting. An air preheater 14 is supported on a base 8 and is connected to a vertical connection part 6 by an expansion-permitting member 15. The steam generator casing can be provided with a steel framework or a framework of water tubes 13.
Patent GB-401095-A (GB)
Title: Process of producing a natural fish oil of high therapeutic value and the product thereof
IPC: C11B1/10
Filed: 1932-10-07
Abstract: Fish-liver oils having high contents of vitamin A, and in some cases vitamin D also, are obtained by steaming fish livers at a temperature which is maintained below 100 DEG  C., discarding the aqueous liquid thus produced, rapidly cooling the residue, extracting the oil from the cooled residue by means of an organic solvent, and subsequently removing the solvent from the extracted oil.  Livers of halibut, salmon, red perch, mackerel, porbeagle, and whales are specified.  In carrying out the process the livers, which are preferably those of halibut, are steamed in a tin kettle for thirty to forty-five minutes while stirring, the steam being introduced by a pipe into the bottom of the kettle at such a rate that the temperature is maintained preferably at 70-80 DEG  C.  The aqueous liquid is discarded, and the residue cooled rapidly, preferably to freezing point.  If the residue is to be stored before extraction, it is further cooled first to about - 10 DEG  F. or lower in cans, and then maintained at a temperature of, or slightly lower than 0 DEG  F. until extraction, protection from oxidation being afforded by a layer of paraffin wax or carbon dioxide gas on the surface of the residue.  The extraction is carried out with peroxide-free diethyl ether or other suitable solvent.  The extract is filtered and evaporated in vacuo, the solvent being preferably recovered.  The halibut liver oil produced may have its vitamin A potency altered by dilution or concentration to any desired point.  The relative contents of vitamins A and D in the concentrate may be adjusted by the addition thereto of standardized amounts of vitamin D, irradiated ergosterol, or any oil-soluble antirachitic factor.ALSO:Halibut liver oils produced by a particular extraction process may have their vitamin A potencies altered by concentration to any desired point, and the relative contents of vitamins A and D in the concentrates may then be adjusted by the addition of standardized amounts of vitamin D, or irradiated ergosterol or any oil soluble antirachitic factor.  A preferred proportion between the vitamins A and D potencies is stated.

Filed: 1962-07-20
Abstract: 1,046,030. Engine turning gear. ENGLISH ELECTRIC CO. Ltd. July 16, 1963 [July 20, 1962], No. 27965/62. Heading F1K. [Also in Divisions B7 and H2] An aircraft electric power supply system comprises an electric, e.g. A.C. generator 13 drivably coupled through a constant speed drive 12 selectively to either an air turbine 14 or an associated engine 10 of the aircraft. When a selectively operable disconnect device 11 is engaged the engine 10 can be started through a free wheel 15 by the turbine 14 which is disconnected by the free wheel when the engine is operating and drives the generator. If the engine is inoperative the device 11 is disconnected whereupon the generator is driven by the turbine 14 which is supplied with air under pressure when the aircraft is grounded from either an external supply or an auxiliary source on the aircraft, or when in flight from either the latter source or another main propulsion engine. Fig. 2 shows the gearing interconnecting the system components.

Abstract: 1,167,297. Testing soil. STICHTING WATERBOUWKUNDIG LABORATORIUM. June 13, 1968 [June 16, 1967], No.28088/68. Heading G15. [Also in Division G4] In apparatus for determining the shearing resistance of the soil a tube 1 Fig. 1 to be pressed into the soil encloses a coaxial rotatable rod 2 carrying at the lower end a plurality of vanes 3 and adapted to be driven at the upper end through a torsion measuring device, a signal emitter being disposed within the tube, as near the vanes as possible, to give signals indicating the angle of movement of the vanes. The emitter is sealed inside a casing 5 Fig.3 and comprises a contact disc 7 having alternate conducting and non- conducting segments co-operating with brushes 11 mounted on a ring 10, connected to the driving rod 2. The disc 7 is free on the rod 2 but is held stationary with respect to the tube 1 by a magnet ring 13 outside the casing 5. The brushes are connected to a transmitter 12 adapted to transmit at one frequency when the brushes are interconnected through the disc 7 and another when they are not. The signals are capacitively picked up from the rod at the ground surface and used to step a motor the position of which therefore indicates the position of the lower end of the rod 2.

Title: Improvements in or relating to electromagnetic relays
Inventor: LENEY ERIC NORMAN
IPC: H01H51/06
Filed: 1954-09-30
Abstract: 776,879. Electromagnetic relays. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. June 7, 1955. [Sept. 30, 1954], No. 28156/54. Class 38(5) A relay, Figs. 1, 3, 5, comprises a magnetic bracket 11 supporting a pair of electromagnets 13, 14 controlling an armature 17 pivoted on the core of the magnet 14, so that when the magnets are energized the armature is attracted towards the core of magnet 13 as shown in the drawings. A spring 18 of channel-section over part of its length carries the armature, and is trifurcated at its fixed end, the outer arms being mounted by screws 20 on lugs of the bracket 11 and the centre arm being downwardly tensioned by the head of a screw 22 entering a tapped hole in the bracket, whereby the armature is biased to its released position. The spring 18 also carries a contact-operating card 19 having slots 46 receiving the ends of wire contact springs 24, 25 biased towards stationary leaf contact springs 29, the arrangement being such that when the relay is energized the contact sets on the top of the relay " make' and those beneath "break." The armature travel in both directions is limited by adjustable stops comprising a member 39 having a lower threaded portion 40 screwed in the bracket 11 and an upper threaded portion 42 having an elongated nut 45. The threaded portion 42 passes through a clearance hole in the spring 18 and the downward movement of the armature is limited by a rim 41 on the member 39 so that there is always a small air gap between the armature and the core of the magnet 13. The member 39 is locked in its adjusted position'by an elongated nut 43. The released position of the armature is determined by the nut 45 which is locked by a nut 44. To ensure that the contacts 24, 25 are out of engagement with the bottoms of the slots 46 when they are engaging their respective fixed contacts 29, the latter are adjustably positioned by insulating studs 38 carried on the ends of tubular nuts 37 threaded on rods 35 screwed into lugs 34 of the bracket 11, the nuts 37 being locked by nuts 36. In a modification, Fig. 6, the armature 53 is held against the core of magnet 14 by the U-shaped end of a spring 55 straddling the armature, the latter having a V- shaped groove receiving the bight of the U. The armature is biased to its released position by a spring 58 engaging the head of a pin 57, and carries a card 59 operating flat movable contact springs 60. Reference has been directed by the Comptroller to Specification 569,268.
