Title: Flavouring composition
Inventor: WESLEY FRANK
IPC: A23L27/60
Filed: 1967-10-20
Abstract: 1,133,298. Flavouring compositions. NESTLE'S PRODUCTS Ltd. 20 Oct., 1967, No. 47761/67. Heading A2B. A flavouring composition which may be added to tomato soup or puree, comprises an edible oil or fat (e.g. butter, groundnut oil or hydrogenated groundnut oil) and the volatile flavour and aroma components of fresh tomatoes. The composition may be prepared by evaporating a pulp or juice derived from tomatoes and allowing the aqueous vapour to meet a film of oil or fat which extracts the flavour and aroma components from the vapour. Alternatively the aqueous vapour may be condensed and the resultant liquid mixed with oil or fat and the oily phase separated by centrifuging, or mixed with oil or fat above the m.p. of the oil or fat and cooled to allow the oil or fat to separate as a solid.

Title: Improvements in or relating to automatic telecommunications exchange systems
IPC: H04Q3/00
Filed: 1969-10-01
Abstract: 1,256,374. Automatic exchange systems. SIEMENS A.G. 1 Oct., 1969 [2 Oct., 1968], No. 48144/69. Heading H4K. Connections between exchanges of a first multi-exchange system are established by relaying the identity of the wanted station from the calling exchange to adjacent exchanges and from them to further exchanges until the exchange is found which records the wanted station identity, connections between stations of the first multi-exchange system and stations of a second multi-exchange system being established by the same technique but, because the number dialled in the second system for a station in the second system may not be the same as the number dialled in the first system for that same station in the second system, a conversion from one number to the other is made when the search for a wanted station extends from the first system into the second system. As shown the station T1 in the exchange system A has the numoer 100 in the system A but has the number 120 when dialled for in the system B; these particulars being recorded in the intersystem gateway exchange B1. Conversely, station T2 in system B has the number 300 in system B but has the number 200 when dialled for in the system A; these particulars being recorded in the inter-system gateway exchange A4. As a search extends to a gateway exchange the necessary conversion of number is made before entering the other system. The interexchange links may comprise junction groups or be frequency or time division multiplex highways on which phase or pulse-code modulation is employed. The identity of the wanted station may be relayed together with the identity of the calling station so that channels seized for a search function may be released as the search progresses and the connection be established backwards from the wanted station when this is found. Alternatively, all the search channels are held until the wanted station is found, a connection being established by a selection from the search channels.

Title: Once through vapor generator
Inventor: SPRAGUE THEODORE SMITH
IPC: F22B29/04
Filed: 1963-12-06
Abstract: 1,029,789. Steam -generators. BABCOCK & WILCOX CO. Dec. 6, 1963, No. 48321/63. Heading F4A. A once-through steam generating unit comprises a feed pump 24 supplying water from a deaerator 20 through a feed water control valve 50 and a feed water flow meter 41 to a boiler having a number of parallel tubes 4 between inlet and outlet headers 26, 28 and heated by a heat source 8 which may be fossil fuel fired burners or heating fluid from a nuclear reactor system. Heated fluid passes via lines 32, 34 into the upper and lower portions of a steam drum 6 containing in its lower portion water 36 maintained by the flow through pipe 32 at saturation temperature. Steam contained in the upper portion 38 of the drum passes through a steam flow meter 40 to a turbine 10 and a condenser 14. Condensate is returned to pump 18 via the deaerator which also receives low-pressure steam through line 22 from a turbine interstage. An emergency line 42 from the lower portion of drum 6 leads through a valve controlled branch 42A to the deaerator and acts as a blow-down line. A second branch 42B having a non-return valve 44 permits flow only in the direction from the drum to the tube inlet header 26 when the pressure at the header falls below that in the drum, e.g. when pump 24 stops. The control 46 receiving signals from the steam and water flow meters operates valve 50 to maintain the two flows substantially equal and is biased by a signal from a water level indicating device 48 located on the drum 6 to maintain the water level in the drum at a predetermined level.

Abstract: 1413036 Transistor gating circuits; television WESTINGHOUSE ELECTRIC CORP 22 Oct 1973 [20 Oct 1972] 49010/73 Headings H3T and H4F A sample and hold circuit, Fig. 5, is used to remove noise and switching transients in the output of a CCD apparatus. This apparatus may be a photo-sensitive imaging device (10, Fig. 1, not shown) the charge packets therein being transferred by control signal #T into a two-phase parallel-to-serial converting CCD shift register (14). Charge packets from the final stage of the shift register are fed by a switch 16 controlled by a signal #n into a minority carrier detector circuit comprising a diode 18. The switch is formed by an electrode (34) overlying the insulation layer (28, Fig. 2, not shown) and the diode is formed by a p-diffusion (40) in the substrate (26). The read out circuit Fig. 5, includes a capacitance CN which is first charged by FET 20 to -VR and at the end of this RESET period (Fig. 6, not shown) retains a voltage representing Nyquist noise level. Then (READ RESET) a switch 76 in the sample and hold circuit closes to cause a capacitor 74 to charge to this noise voltage (Vg). Thirdly, in response to #M the diode 18 charges CN in #M, time to a level representing the detected charge packet (black or white) this level also including the noise component, the switch 76 now being open again. Finally a switch 92 passes the net charge on C74. which represents the charge packet minus the noise, to a capacitor 94. The voltage on C94 is fed out by an amplifier 98.

Title: Fluid flow control valve assemblies
IPC: F16K15/18
Filed: 1970-10-24
Abstract: 1374240 Fluid regulation H ZADOW and H R J ZADOW 22 Oct 1971 [24 Oct 1970] 50607/70 Addition to 1307820 Heading G3H [Also in Divisions Fl and F2] A control valve assembly comprises a first chamber 1 having an inlet port 3, an outlet port 21 and a plate movable, e.g. by pulses applied to ports 6 and 7, between a position in which it does not obstruct the outlet port 21 to the position shown in Fig. 2 in which it closes that port, and a second chamber 8 having an entry port 14 connected to the outlet 21 of the first chamber, ports 12 and 25 and a plate movable, e.g. by pulses applied to a control port 203, to connect port 12, which may be connected to a single-acting cylinder as described in the parent Specification, to the entry port 14 and to disposal port 25. The two chambers may be arranged side-by-side, Fig. 6 with a slidable rod 210 arranged between the plates so that operation of one may effect operation of the other, and the outlet 216 of the first chamber may be directly connected to the port 12. The first chamber may have two outlets 4, 5, Fig. 3, connected respectively to the entry ports of corresponding further chambers 8, 9 each with a pair of further ports 12, 25 and 13, 26. The plates of the chambers are associated with sliding rods 204, 205 so that pulses applied to ports 208, 209 shift them all to the left and all to the right respectively, so that fluid under pressure is fed either through port 12 or port 13 to one side or the other of a double-acting cylinder, the other one of the ports 13 or 12 being connected to waste through port 26 or 25. The plate in each chamber may be moved by temporarily blocking the outlet which it is at that time closing, instead of by applying a pulse from a control port. Thus a chamber 225, Fig. 8, with a plate 226, an inlet 227 and two outlets 232, 233, may have plungers 230, 231 by which passages 228, 229 leading to the outlets may be blocked. If the plate 226 is in its left hand position as shown, then temporary blocking of the outlet 229 covered by the plate will result in the plate being drawn across the chamber so as to switch the flow from the outlet 232 to the outlet 233. A chamber having one main outlet may have one opposing orifice (234), Fig. 9 (not shown), provided with a plunger (235). If the main outlet is closed by the plate, the latter may be moved to open the main outlet by temporarily closing the main outlet and withdrawing the plunger so as to open the orifice. Chambers with two outlets may each have two plates 247, 248, Fig. lOb, which normally block the corresponding outlets unless held away from them by rods 249, 250. In all of the arrangements, the plates may be thin foils which readily peal away from the sides of the chambers, or alternatively the chambers may have recesses behind the plates in the vicinity of the control ports to achieve a similar effect.

Filed: 1974-11-25
Abstract: 1481816 Laminated absorbent tissue paper PROCTER & GAMBLE CO 25 Nov 1974 [26 Nov 1973] 50964/74 Heading B5N A multilayer absorbent tissue paper comprises a central ply 2 of less than 10% total stretch, printed with water-resistant reinforcing  resin in an overall pattern covering 15-50% of the total surface area of at least one face and intermittently bonded to creped outer plies 34, 35 each having a total stretch greater than the unprinted central ply at embossment points (which preferably match) previously formed in said outer plies. The outer plies may have 15-50% crepe and may each be embossed over 7-50% of the surface area. All the plies preferably include a wet-strength resin. As shown, the ply 2 is printed on both faces by rollers 7, 8 with a self cross-linking resin emulsion (examples of which are given), the patterns being in or out of register. The resin is allowed or caused to dry, e.g. by hot air distributors 18, 19 (other means also being mentioned), and may be cured in which case a separate laminating adhesive is required for bonding. Preferably the ply 2 is dried to 2-8% moisture content but not cured, and then serves to bond plies 2, 34 and 35 under pressure applied at the matching embossment points of rollers 26, 27. The plies 34, 35 are embossed between rubber rollers 30, 31 and rollers 26, 27. Not all embossment points need match if the plies 34, 35 are insufficiently embossed, extra adhesive is necessary. The laminated product is momentarily crushed between rollers 48, 49 to improve softness and the resin may be finally cured by hot air distributors 52, 53 (other means also being mentioned). The non-bonded portions of plies 34, 35 expand outwards on wetting.
