Patent GB-765339-A (GB)
Title: Liquid fuel supply systems for prime movers
Inventor: WARNE EUGENE HAROLD
IPC: F04C14/02
Filed: 1953-07-28
Abstract: 765,339. Gas turbine plant; centrifugal pumps. LUCAS (INDUSTRIES), Ltd., J. July 21, 1954 [July 28, 1953], No. 20868/53. Classes 110 (1) and 110 (3). In a liquid fuel supply system for a prime mover such as a jet propulsion or gas turbine plant, of the kind in which the fuel is supplied to a burner by a centrifugal pump driven at a speed corresponding to that of the prime mover, a positive-displacement pump is arranged in parallel or series with the centrifugal pump, and a valve normally closed by a spring and responsive to fuel pressure short-circuits the positive-displacement pump when the speed of either pump is adequate to produce a pressure which will open the valve. Fig. 2 shows a centrifugal pump a delivering liquid fuel by way of a non-return valve h and a manual or automatic flow control d to a burner b. A positive displacement pump, such as a gear pump e, is connected in parallel with pump a by way of pipes f, g and non-return valve i. Both pumps are driven by the gas turbine or an associated source of motion, and at low speeds the burner b is supplied by pump e. When the delivery pressure of pump e has risen to a predetermined value, the pressure in pipe g moves a piston n to open a valve k against the action of a spring m to short-circuit the pump e through a by-pass j. The burner b is then supplied by pump a. Instead of being connected, as shown, to pipe g the cylinder containing piston n may be connected to the delivery side of pump a; valve k is then opened by pump a instead of pump e. A valve q, operable by an electromagnet r or other means, may be provided. When valve q is closed, the system operates as described above, but when it is opened, it connects to the pipe g a by-pass s containing a pair of restricted orifices t, the space between the orifices t being connected to one end of the cylinder containing the valve k. Valve k then remains closed until the pressure in pipe g reaches a higher value than would otherwise have sufficed to open it. Fig. 3 shows an alternative arrangement in which pump e is arranged in series with pump a. When the discharge pressure of pump a reaches a predetermined value, it acts by way of a passage w to open a valve u against the action of a spring v, thereby short-circuiting pump e. Passage w may alternatively be situated in the position shown dotted, in which case the valve u is opened by the discharge pressure of pump e.

Filed: 1971-04-19
Abstract: 1309049 Semi-conductor devices ELECTRONIC ARRAYS Inc 19 April 1971 [2 Feb 1970] 21187/71 Heading H1K The gate oxide of an operating MOS transistor 30 is protected against breakdown due to voltage overload on the gate electrode 31 by the provision of a protective MOS transistor beneath the bonding pad 12 to which the gate signals for the transistor 30 are supplied, the oxide layer beneath the bonding pad 12 being thicker than that beneath the gate electrode 31 of the operating transistor 30. An extension of the drain region 21 of the protective transistor is connected to the gate electrode 31 of the transistor 30, the input signals to the latter transistor passing through this extension from the bonding pad 12, which is connected to the drain region 21 at 17 and which also serves as the gate electrode of the protective transistor. The source region 25 of the protective transistor, which may be interdigitated with the drain region 21 as shown to provide a large currenthandling capacity, is grounded so that excess voltage on the bonding pad 12 turns on the protective transistor and is safely leaked away without damaging the operating transistor. Additional breakdown protection may be provided by thinning an area 41 of the oxide layer 20 adjacent the extension of the protective drain region 21 and depositing a grounded metal layer 42 thereon, so as to reduce the breakdown voltage of a portion of the pn junction between the region 21 and the substrate 10 to below the gate oxide breakdown voltage of the transistor 30.

Abstract: 1349572 Recording liquid flow over surface; colour changing indicator coatings CIBAGEIGY AG 19 April 1971 [13 Feb 1970] 21531/71 Headings B1X and B2E In visually recording liquid flow over a solid surface having a dry film coating, containing a first reagent freely diffusible in the coating, a liquid which contains a second reagent is caused to flow over the coating such that the liquid diffuses into the coating and the second reagent, which is freely diffusible within the coating, forms a stable non-difusible coloured reaction product with the first reagent. The reaction product is not readily soluble in the liquid. The film coating may be of a hydrophilic gel forming material, e.g. gelatin, casein methyl cellulose, or polyvinyl alcohol which can be treated by cross-linking or hardening agents. The solid surface may be cellulose triacetate, paper coated with a gelatin containing filling agents, polyester film, fibre fleece made from polyamide fibres, or foil. The reactions may involve the formation of azo dyestuffs from a diazo compound and coupling compound, or acid-alkali components with an indicator, or ferri or ferro-cyanides of alkali metal with the water soluble salts of iron or copper. The process may be used in the evaluation of conditions in photographic processing baths, mixing vessels, pipelines or model hulls.

Abstract: 412,913. Packeting eggs. BARTON, C. N., 119, Worple Road, Wimbledon, London. Oct. 3, 1932, No. 21813. [Class 94 (i).] Eggs are packed in partitioned holders or fillers which are opened out from a collapsed state and fed to the filling station, which may be in conjunction with an egg feeding and grading apparatus as described in Specification 412,912, [Group XVIII]. The loaded fillers may be fed to a packing or wrapping station. The fillers F, which when opened present the appearance shown in Fig. 7, are fed to the right in a collapsed state in a magazine 1, Fig. 3, by a pusher 5 operated by a weight 6, and come to rest against a stop plate 4. A plunger 13 forces one through an opening 12 on to a plate 15 so as to abut against a guide plate 18 and rear plate 20, Figs. 5 and 7. A finger 16 on a conveyer 17 engages one edge and opens it into the position shown in Fig. 7, with the front edge engaging a conveyer 21 having chocks 22 which engage the filler and transport it towards the grading and delivery apparatus. A separate opening and feeding device is provided for each section of the grading apparatus. If fillers of half the size are to be used, partitions and guiding plates are placed to adapt the apparatus accordingly. The driving mechanism is common to the apparatus and the feeding and grading apparatus, and the various operations are carried out in timed relationship. A shaft 25, Fig. 3, rotates as each egg is graded and rotates change speed gears 30, 31 by bevel gearing 26, 27. According to the setting, which depends on the number of eggs to be packed in each filler, a cam pawl 37 moves the filler conveyer 21 each fourth or seventh step to bring a row of cells beneath the delivery and graining apparatus, and to take a filled row away. At each second step of the conveyer 21, the plunger 13 descends to eject a collapsed filler from the magazine for opening by the finger 16. A clutch may be fitted on the shaft 25 for disconnecting the several parts of the apparatus.
