Title: Improvements relating to average-speed indicators
IPC: G01P11/00
Filed: 1949-06-22
Abstract: 736,212. Average - speed indicators; indicating apparatus. MAMBRO, G., DI. Aug. 16, 951 [June 22, 1949], No. 16559/49. Classes 106 (3) and 106 (4). Means for continuously indicating automobile time distance ratios comprises a mileometer 6, Fig. 1, and a clock 5 driving gearing including screws 31, 27 (called " worms ") arranged transversely to each other, a nut 30 on one screw (31) having bracket means 29, 32, 33 which carry the other screw (27) on which moves a nut 34, Fig. 2, having a mechanical connection with a pointer 43 adapted to indicate on dial 44 the average speed required for the remainder of a journey for which the distance to be travelled and time to be taken are registered on indicators 45, 46 respectively driven by the screws 31, 27. The means may also be used to indicate the average speed for the distance already travelled. As shown, a pinion 7, driven from the hour spindle of the clock, drives shaft 14 through differential gearing including planet wheel 11 mounted on collar 10 slidably keyed to the shaft, and a pinion 12 fixed to a ratchet wheel 13 normally held stationary by arms 20, 24 and spring 25, Fig. 4. Upon an overload on shaft 14, wheel 13 rotates and urges arm 20 outwardly until stop 22 engages a slot 26. The shaft 14 may be axially adjusted so that either of two bevel pinions 15, 16 may be engaged with pinion 17 on shaft 18 which drives screw 27 through sliding pinion 19 and pinion 8 held in contact by bracket 19a. A worm 37 on mileometer shaft 31a drives through a similar differential gearing and overload cut-out device a shaft 38 geared to screw 31 mounted in a frame 28 secured to the automobile dashboard. In use, the indicators 45, 46 are set by knobs 48, 47 respectively, at the start of a journey, to the required distance and time. Then at any subsequent time, the indicators will display the distance still to be travelled and the time in hand. As screw 31 rotates, nut 30 and brackets 29, 32, 33 carrying screw 27 are moved horizontally, and the rotation of the screw 27 moves nut 34, constrained by rod 35, vertically so that the latter is always set to a position corresponding to the time/distance ratio. Thus the pointer 43, connected to lever 41 spring- urged into engagement with roller 42 on the nut, always indicates the required average speed. If indication of average speed over the distance travelled is required, knobs 47, 48 are pushed upwards to adjust axially shafts 14, 38 and reverse the drives to screws 27, 31, indicators 46, 45 being initially set at zero. In a modification, an electric clock drives screw 27 through a flexible drive and overload cut-out friction clutch. In the Provisional Specification a different construction of average-speed indicator is described in which the gearing drive by the mileometer and clock includes elongated pinions and toothed racks.

Title: Improvements in and relating to telescopic taps
IPC: B67D3/04
Filed: 1960-05-11
Abstract: 915,586. Valves. FUTS METALLIQUES GALLAY S.A. May 11, 1960 [May 28, 1959], No. 16687/60. Class 135. [Also in Group XVII] A telescopic tap is formed from three concentric tubes, an open-ended outer tube 3 fixed by an annular base I to a container such as a barrel, an intermediate tube 5, sliding within the tube 3, open at its rear end and formed with a side orifice 41 at its forward end, the forward end being otherwise closed by means 33, 35, 39 to which is connected a shackle 37 and an openended inner tube 7 urged forwardly by a spring 9 until a lug 53 on the tube 7 reaches the end of a slot 55 in the outer tube 3. The tube 5 can be pulled forwardly by the shackle 37 until a lug 29 on the tube 5 engages the end of a second slot in the outer tube 3. With the tubes 5 and 7 in their extreme forward positions, as shown, liquid can flow from the container through the opening 41. When the tube 5 is pushed inwardly the inner tube 7 remains stationary until the sealing means 39 abuts the forward end of the inner tube 7, in which position the opening 41 is closed by the tube 7. Further inward movement by the tube 5 then forces the inner tube 7 back against the action of the spring 9. When the tube 5 has been pushed inwardly to its full extent it is turned manually by means of the shackle 37 to cause the lug 29 to ride up on a helical ramp 31 at the rear end of the outer tube 3 and so hold the whole assembly in its inner position and squeeze a sealing ring 59 against the annular base 1. When the lug 29 is not engaged on the helical ramp 31, the spring 9 pushes the tube 7, and hence the tube 5, out of the container. The tube 5 can then be drawn outwardly by means of the shackle 37, to cause the orifice 41 to be opened to the desired extent.

Title: Computer systems
IPC: G06F9/40
Filed: 1974-04-17
Abstract: 1509193 Data processing NATIONAL RESEARCH DEVELOPMENT CORP 17 April 1975 [17 April 1974 14 June 1974] 16766/74 and 26497/74 Heading G4A A data processing system is adapted to process a set of nested program blocks and to preserve the states at the beginning of each block of those pre-existing items of information whose states change during the block whereby those items of information may be restored to their states prevailing when execution of a block was begun. As described the system is adapted to process error recovery programs consisting of nested "recovery" blocks each including a primary block, possibly one or more alternative blocks, and an acceptance test. Each primary or alternative block may contain one or more further recovery blocks to form the nested structure. On entering a recovery block e.g. recovery block II, the primary block, IIa, is executed, the initial states of any variables which are changed during the block being buffered in a cache memory as and when their states are changed. When the block is completed the acceptance test IIt is executed. If the test fails all the variables are restored to their states prevailing before the primary block IIa was started and the alternative block IIb is executed followed by the acceptance test IIt. If at any stage the test succeeds the recovery block II is terminated, the variables, apart from any which are purely local to the recovery block which are discarded, e.g. J, being kept in their current states. Processing then continues in the next higher level block Ia if such exists, at the point following the completed recovery block. Two basic embodiments are described, implemented by a micro-programmed or hardwired system, full details being given of the procedures involved in storing data in the cache memory to keep track of the states of variables down through the various levels of the nested structure. In a modification an arrangement is described which can selectively retain the states acquired by certain variables during a block even when processing is abandoned or an alternative block is attempted.

Title: Improvements in and relating to the treatment of silicate ores
IPC: C01B33/26
Filed: 1936-06-17
Abstract: Silicate ores containing, besides silica, one or more amphoteric metal oxides such as zirconium, titanium, aluminium, iron, or chromium oxide, and more particularly ores of zirconium, thorium, or beryllium are calcined with a barium compound such as barium carbonate in such amount that the silica is converted to dibarium silicate and one or more of the amphoteric metals to the barium salt thereof, fluxing additions or an excess of barium carbonate which would tend to fuse the mixture at the operating temperature of say 1400 DEG  C. being avoided.  Reaction may be effected in a rotary or tunnel furnace, the ore and barium carbonate being briquetted in the latter case.  In the case of zircon, a mixture of dibarium silicate and barium metazirconate is obtained which may be used as a refractory.  Or the mixture may be crushed with hot water to form and remove barium hydroxide and leave a mixture of monobarium silicate and barium metazirconate, the latter mixture being treated either with hot sodium or potassium carbonate solution to form and remove sodium or potassium silicate, or first with carbon dioxide to form silicic acid, and then with caustic soda to form and remove sodium silicate.  In either case a mixture of barium carbonate and metazirconate remains, which may be calcined at 1400--1500 DEG  C. to obtain a refractory consisting of barium orthozirconate, and the latter, if desired, may be reheated with zirconium oxide to obtain a refractory consisting of the metazirconate.  The products contain barium titanate and ferrate, and a small amount of lime and magnesia, if these bases are present in the ore.  In a modification, the barium carbonate-metazirconate mixture may be treated with hydrochloric acid to obtain a solution of zirconium and barium chlorides, the solution be first treated with ammonia to precipitate zirconium hydroxide which is calcined to the oxide to obtain a refractory containing a little titanium and iron, and then with carbon dioxide to precipitate barium carbonate which may be re-used; or the solution may be added to sulphuric acid, gypsum, or a soluble sulphate to precipitate barium sulphate, and the zirconium then be precipitated by lime.ALSO:Zirconium silicate ore (zircon) is calcined at 1400 DEG  C. with a barium compound such as barium carbonate to obtain a refractory comprising a mixture of dibarium silicate and barium metazirconate.  The mixture may be crushed with hot water to obtain a mixture of monobarium silicate and barium metazirconate, from which by removing silica as alkali silicate by means of alkali carbonate a mixture of barium carbonate and metazirconate may be obtained.  The latter mixture may be calcined at 1400-1500 DEG  C. to obtain a refractory consisting of barium orthozirconate, and the latter, if desired, may be reheated with zirconium oxide to obtain a refractory consisting of the metazirconate.  The products contain barium titanate and ferrate, and a small amount of lime and magnesia, if these bases are present in the ore.

Abstract: 594,857. Engine stop-gear. GENERAL MOTORS CORPORATION. July 3, 1945. No. 16855. Convention date, July 3, 1944, [Class 122 (iv)] In a protective control system for an internal combustion engine in which the lubricating pressure cuts off the fuel supply to the engine when the pressure falls below a predetermined value, the pressure operates through an electric switch and an electric relay having contacts in the control circuit retards the cut-off at starting to allow the pressure to build up. Fuel is pumped by a motor FM operated by a battery BAT under control of a switch FS, the supply being regulated by a plunger 40 in a pressure cylinder 39 in which the pressure is controlled by an electric-pneumatic governor consisting of four elements a ... d, linked to the governor to operate the engine at constant speeds between idling and maximum speed or to shut down the engine. An air-pressure pipe 41 feeds the element d, and an electro-magnetic shut-off valve isolates it from the elements a, b, c, these being inoperative when the valve is de-energized and the element energized. Idling occurs when all the elements a ... dare de-energized and the combination of the element d with any of the elements a ... c provides operation at selected speeds. On reduction of the lubricating oil pressure below the preselected value, the contacts of a pressure switch PS open and de-energize a relay R permitting its armature to fall to the position shown. The valve e is de-energized and closes, rendering inoperative the e ements a ... c while the element d is energized ; the engine is thereby stopped. Simultaneously, a signal light SL is energized. A delay relay TR delays the mating of its contacts on closing of the starter switch SS until the lubricating oil pressure has had time to build up to the pressure necessary to close the pressure switch contacts and energize the relay R. In a modification, the speed setting is operated directly by a hand throttle.
