Abstract: 1,251,800. Alcoholic beverages; distillation of alcoholic liquors. IRISH DISTILLERS Ltd. and W. H. A. WEBB. 29 Jan., 1969 [23 Nov., 1967] No. 53429/67. Heading B1B. A self-flavoured spirit similar to whisky, brandy, rum or calvados is produced by continuously passing a fermented liquor of low alcohol content through a pot wherein it is heated for a determined time in order to develop desired flavours, and distilling the effluent stream from the pot in a fractionating column to separate a fraction of the required high alcohol content. The pot is preferably made of or lined with, copper. In an example, "Irish" whisky is produced from distillery wash, containing about 6% by weight of alcohol, by heat-treatment and distillation in the apparatus shown. The wash is pumped from tank 2 into pot 8, which is heated by steam coil 10, where the wash is boiled under reflux. After a residence time of 5 hours, the wash overflows from pot 8 and is pumped to plate-type distillation column 16. Steam is introduced into the base of column 18 through injector 18, and the spent wash is discharged from the base. Some of the condensate from reflux condenser 22 is pumped to pot 26 where the liquid is maintained at the boiling point by electrical heater 28. After a residence time of 95 minutes, the liquid overflows to column 32 (a glass tube with stainless steel rings) heated by electrical element 34. Spent lees are discharged from the base of column 32. Some of the overhead condensate from reflux condenser 38 is pumped to pot 42 where the liquid is maintained at the boiling point by electrical element 41. After a residence time of 185 minutes, the liquid overflows into distillation column 44 (a thermally insulated glass tube filled with stainless steel rings) which is heated by electrical element 46. Liquid withdrawn from the base of column 44 is returned to pot 26. Some of the overhead condensate from reflux condenser 48 is pumped to column 56 (of similar design to column 44). Some of the overhead condensate from reflux condenser 58 is returned to pot 42. The liquid withdrawn from the base of column 56, which is passed through cooler 62 and collected in receiver 64, is the required whisky product. It is necessary to operate the apparatus for some days before equilibrium is reached, and the characteristics of the various fractions are established. An apparatus suitable for the continuous production of "Scotch" whisky is described with Fig. 3 (not shown); this apparatus comprises two pots and associated columns. The liquid and vapour withdrawn from the head and base, respectively, of the first column are used to preheat the feed wash. The level of liquid in the pots and in the sumps of the columns is automatically controlled.

Abstract: 1297013 Facsimile apparatus MEAD CORP 28 Jan 1970 [3 March 1969] 4190/70 Heading H4F The video signal derived by optically scanning an original is first converted into digital information representing each incremental area of the original according to its relative density, this information is then processed into a plurality of output code signals which define the relative density of each incremental area as the number of dots to be reproduced on a recording sheet. Intermediate magnetic recording is utilized. As described each reproduced incremental area is subdivided into nine (3 x 3) dot areas, and one line scan at the transmitter is reproduced at the receiver by three successive line scans, e.g. three rotations of a recording drum past an electrostatic ink spot recording device which is continuously or step-wise moved. The density (contrast) of the resulting half tone print may be adjusted during the digital signal processing step. The original may comprise a positive or negative film and may for example be one of a set of colour separations. Instead of a 3 x 3 format providing ten density values corresponding to how many of the nine possible points in the grid are blackened in print-out, other matrix formats are possible, e.g. 4 x 4, 4 x 5, 5 x 5. The recorded dots may overlap rather than be adjacent each other, and the images may be reconstructed repeatedly. Multicolour prints may also be produced by precise overprinting with different colours.

Abstract: 1303244 Substation circuits; transistor amplifiers JOSEPH LUCAS (INDUSTRIES) Ltd 2 April 1970 [15 May 1969] 24746/69 Headings H4T and H3K The number of a subscriber can be dialled and the progress of the call monitored on a loudspeaker by operating a single switch whereby when the connection is made the handset is lifted to restore the circuitry to its inoperative state. The telephone line pair 11, 12 is connected to bus-bars 14, 15 through a full wave rectifier and a signal connection is made through capacitor C5 to amplifier 21 whose output is connected to a loudspeaker. When number button switch 22 is operated trigger circuit 16 is energized through filter 17 which itself connects line 18 to line 15 thereby energizing timing circuit 19 and amplifier 21. The line is looped through filter 17 and dialling pulses can be sent by open-circuiting the loop. To ensure continued operation of trigger circuit 16 when the loop is opened, a battery is provided and arranged to be charged up from lines 11, 12. The progress of a call is heard on the loudspeaker and when the call is answered the handset is lifted causing circuit 13 to provide an input to trigger circuit 16 to turn it off. If the number is unobtainable timing circuit 19, which includes a field effect transistor, is used to turn off the trigger circuit. Alternatively it can be turned off manually by switch 23. Amplifier.-Amplifier 21 is of the push-pull type comprising a pair of transistors (84, 85) whose emitters are connected together and whose bases are connected through two diodes (86, 87). The collectors are connected to lines 14, 18 and the base of transistor (84) is connected through a loudspeaker (89) to line 14. The signal is applied to the common emitter circuit and also through a diode and a further transistor (91) to the base of transistor (85).

Abstract: 1305311 Shock absorbers JONAS WOODHEAD Ltd 13 April 1970 17450/70 Addition to 1267508 Heading F2S The main piston 8 of the shock absorber of Specification 1,267,508 is provided with a passage 13a and a valve element 61 which maintains the passage 13a closed or substantially closed except when, during movement of the main piston 8 in the direction out of the main cylinder 1, the pressure across the main piston 8 exceeds a predetermined value whereupon the valve opens. The main piston 8 is connected to a subsidiary piston 9 which slides in a subsidiary cylinder 25 at the beginning of the contraction stroke and at the end of the extension stroke, providing a threshold resistance to initial inward movement of the main piston 8 which is greater than the resistance to its final outward movement. When the main piston 8 begins to move into the cylinder (R.H.S. of Fig. 2) the 0-ring 38 seats against the upper part 34 of the subsidiary piston 9 and so fluid between the pistons can only escape to the back of the piston 9 by way of bleed notches 44 (optional). When the subsidiary piston 9 reaches the end of the cylinder 25, the threshold resistance is eliminated, and further inward movement of the piston 8 is regulated by valve elements 15, 16. Outward movement of the piston 8 is controlled by the blow-off valve element 61 and bleed notches 17 until the subsidiary piston 9 enters the subsidiary cylinder 25 (L.H.S. of Fig. 2), where the 0-ring 38 allows substantially free flow of fluid past the piston 9 and out of the subsidiary cylinder. The working fluid is an emulsion of liquid and gas under pressure.

Abstract: 1316120 Casting-machines FISHER GAUGE Ltd 29 Sept 1970 [10 Oct 1969] 50011/69 Heading B3F A pressure die casting machine comprises an injection nozzle 15; a frame 10 having die parts 16, 17, 19 and 21; means 11 supporting the frame 10 and being movable between a lowered position in which the die gate 40 seats on the nozzle 15 and a raised position; and means for floating and anchoring the frame 10 on the support 11. The support 11, Fig. 2, comprises a yoke 25 located about a pillar 26 and pivotally attached thereto via a channel link 32. The frame 10 is supported on plates 38 attached to the yoke, said plates having cavities 39 connected with fluid pressure means. Before initiating the cyclical operation of the apparatus pressure fluid is supplied to the cavities 39 to enable the position of the frame 10 to be adjusted before it is secured to the plates 38. The cyclical seating and unseating of the die gate 40 on the nozzle 15 is carried out by the drive mechanism 42, Fig. 3. This consists of arm 43 pivoted at one end to the channel link 32 and at the other end eccentrically to a wheel 44 driven by a rack 44 and pinion 45. A stop pin 50 bears against the arm 43 when the latter is in its lower position and the die gate is seated on the nozzle as shown in Fig. 3. An anti-clockwise movement of the wheel 44, from the position shown in Fig. 3, raises the arm 43 thus causing the channel link 32 to rotate and move the yoke 25 to the left. Since the end of the yoke is pivoted to a fixed plate 28, this causes a raising of the yoke 25 and thus unseats the die gate from the nozzle. The die plate 19 may then be moved horizontally by pistons 91 to sever the plug in the gate 40 from the casting. The die part 16 is attached to the end of a shaft 60 which is movable by means of a piston ring 75 in an hydraulic cylinder 76, Fig. 6. Within the shaft 60 is a further shaft 77 carrying a collar 78 supporting a ring 65. A second ring 64 is mounted adjacent to the end of shaft 60, both rings having notches therein to accommodate guide keys 62. To close the die, the shafts 60 and 77 are moved to the left until they reach the position shown in Fig. 6, at which point the ring 64 remains keyed whereas ring 65 is located in a recess 62a in the guide keys 62 and is rotated by a finger (68) to move its notches out of alignment with the keys 62. Hydraulic cylinders 71 are then actuated to move wedges 70 against latches 63 which pivot about a pin 63a and bear against the ring 65 so as to lock the die part 16 in position. The apparatus may be used for encapsulating a turbine blade in a block of metal, the blade being located and held within the die cavity by fixed and movable locating pins (106), (110), (104) and (111), the movable pins being moved in and out of the cavity by means of a lever (118), Fig. 8 (not shown), and locked in position by means of a rod 82 extending through the shaft 77 and operated by an hydraulic cylinder 81. The die parts are water-cooled and the lower die part 19 is provided with an aperture 92 through which a lubricant is injected into the die.
