Patent GB-499956-A (GB)
Title: Process for the manufacture of shaped activated carbons
IPC: C01B32/384
Filed: 1937-05-10
Abstract: Shaped active carbons of low apparent density are obtained by soaking a solid organic carbonizable raw material, e.g. brown coal, peat, wood, straw or mixtures thereof in a solution of a chemical activating agent, e.g. zinc chloride or phosphoric acid, admixing therewith already activated carbon, shaping the mixture and calcining it, e.g. at about 600 DEG  C.  The presence of alkali, alkaline-earth or earth metal compounds is preferably avoided. The added active carbon is preferably of low weight and may be made by calcining raw material rich in cellulose with a large excess of activating agents such as zinc chloride or phosphoric acid, and may be added in granular or pulverized form.  According to examples: (1) peat is soaked in zinc chloride solution and 1 pt. of active carbon added to 4 pts. of the mixture.  The mixture is then extruded and formed into granules which are calcined at about 600 DEG  C.  The product weighs about 280-300 gms./litre; (2) peat, sawdust, and pulverized active carbon in the proportions of 6 : 3 : 1 are treated as described above.  The product has a density of 310-340 gms./litre.  Reference has been directed by the Comptroller to Specifications 277,714 and 277,715, [both in Class 90].

Title: Improvements in or relating to the transport of liquefied gas
IPC: F17C13/12
Filed: 1960-04-14
Abstract: 905,990. Storing liquefied gases. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. April 14, 1960 [April 17, 1959], No. 13355/60. Class 8(2). [Also in Group XXXIII] A liquefied gas transport vessel e.g., a tanker (see Group XXXIII) comprises one or more storage chambers 1, Fig. 1, having walls 2 of thermally insulating material e.g., wood lined with impermeable material 3 e.g. steel and the walls are held spaced from the partitions 5, 5a of the tanker structure by insulating ribs 7 and sealing ribs 9; the latter serving to divide the interspace into a plurality of compartments 10 adapted to be charged with an inert gas through valved ducts 11, 12, 13 fed from a manifold 14. The pressure of the inert gas in each compartment is normally maintained just below that of the stored gas and an increase in the inert gas pressure shown by gauges 15 is regarded as an indication of leakage of stored gas through the lined wall 2 and is countered by increasing the pressure of the inert gas in the appropriate compartment 10. The vapour space of each tank 1 is connected to a heat exchanger 18, 18a, Fig. 2, supplied with refrigerant from a line 19, 19a containing a pressure-opening valve 20, 20a responsive to the pressure in each said vapour space; the so-warmed coolant being discharged through lines 21, 21a and the condensed vapour being returned to the storage tanks. In the event of the pressure in the tank falling below that necessary to. force out the liquid during discharge through a valve duct leading from a sump 28 make-up vapour is added through lines 26, 26a and valves 25, 25a which latter may also serve as vent valves.
Patent GB-499101-A (GB)
Title: Improvements in or relating to sheet feeding devices
IPC: B65H9/14
Filed: 1938-05-04
Abstract: 499,101. Feeding sheets. SPIESS, G. May 4, 1938, No. 13373. Convention date, May 4, 1937. [Class 100 (i)] A sheet-feeding device can be adapted for an overlapping stream feed or for feeding sheets singly without overlap by feeding the sheets in succession from a pile to a feed table fitted with a series of intergeared slow moving feed rollers 4, and an alternating set of intergeared rollers 5 moving at a high speed. The sheets are pressed against the rollers 4 or 5 by means of pressure members such as rollers, or balls 19 which are carried by cages secured to rods 20 slidable in guides 21 to permit the balls 19 to co-operate selectively with the rollers 4, for overlapping feed, or with the rollers 5, as shown, for single feed. The rollers 4 are driven from the main shaft 9 by an eccentric gear 10 and a gear 11 carried by links 12, 13 which drives the first roller 4 with an irregular motion adapted to retard the sheets as they near the front stops. For single feed the sheets are first advanced at slow speed from the pile by a roller 6 co-operating with a roller 4, and then at high speed by co-operation of a roller 31 with a roller 5, the rollers 6, 31 being mounted on a lever 32 oscillated by a cam on the shaft 9 so as to operate alternately. The sheet is then advanced by the rollers 5 and balls 19 until the last roller 5 is reached. A swinging carrier 22 carries two sets of balls 19 and is positioned to co-operate with the last roller 5 until the sheet is clear of the preceding roller 5 when the carrier is oscillated to free the balls 19 from the last roller 5. A sheet stop 45 is then raised to stop the sheet temporarily, and then the carrier 22 brings the other set of balls 19 into contact with the last roller 4 and the sheet is advanced slowly to the front stops (not shown). When the rods 20 are moved by a handle 40 to move the balls 19 into contact with the rollers 4 for overlapping feed, oscillation of the carriers 22, 32 is prevented by the engagement of the handle with the carrier 22, and by a stop 41 on the rods 20 which actuates a lever 43 for tripping the actuating mechanism of the carrier 32. The stop 45 is also tripped for overlapping feed.

Patent GB-134590-A (GB)
IPC: H01H47/20
Abstract: 134,590. Scott, M. D., and Eckersley, P. P. Oct. 26, 1918. Wireless signalling; electric oscillations, producing. - Relates to electromagnetic switches specially suitable for use. on aircraft for changing over from wireless reception to transmission, and vice versa. T h e switch is more particularlv adapted for use with thermionic valve transmitters, and is arranged to dim the transmitter valves when the receiver is connected to the aerial, thus preventing the generation of oscillations by the transmitter valves during reception. The electro-magnet A, Fig. 1, is of E-shape with a central winding C. The armature D, pivoted at E and retracted by a spring F, carries an insulating-shoe G bearing contacts H, J, Fig. 4, which co-operate with three spring-pressed contact fingers K, L, M. The aerial A<c> and transmitter X are respectively connected to the terminals S, R. Plugs Y, Y connect with the observer's switch Z<1> and the pilot's switch Z on the joy-stick. Normally, the electro-magnet A is de-energized, and the receiver X is connected to the aerial through the contacts L, J, as shown in Fig. 4. In this inactive position of the switch, a resistance V is included in the circuit of the filaments U and dims the valves. If either the pilot or observer wishes to change over from reception to transmission, he closes his switch Z or Z' and energizes the winding C, with the result that contact is broken at L and made at M (thereby connecting the aerial A<c> to the transmitting set T), and contact is made at K, H (thereby cutting out the resistance V and bringing the filaments up to full glow). In a modification, the switch is so arranged that, when energized, it connects the aerial to the receiver, and the winding C is in series with the filaments, which are thereby dimmed. In order to change over to transmission, the winding C is short-circuited, thereby producing the necessary charge of contacts and at the same time bringing the filaments up to full glow.

IPC: B41F3/58
Abstract: 134,781. Forrester, H. J. C., (Miehle Printing Press & Manufacturing Co.). Oct. 29, 1918. Bed-reciprocating apparatus.-Mechanism for reversing a reciprocating bed at the ends of its travel comprises a reciprocating member which moves in opposite direction to that of the bed during the reversal, and is also disposed so close to the underside of the bed as to be on the same side of the centre of gravity of the press as the bed, to reduce the tendency to tipping or upending of the press. In the arrangement shown, the bed 33 is driven through the main portion of its strokes in opposite directions by gearing including mutilated gears on a shaft 25 operating a shaft 18 having a pinion in gear with a rack 32 on the bed, as described in Specification 134,298. The cylinder 12 is driven at constant speed from the power shaft 14. The reversing-mechanism comprises a sliding bar 37 reciprocated by a crank 21 on the shaft 18 connected to it by a rod 35. Racks 40, 41 on the ends of the bar 37 are in gear with pinions 42, 43 on stationary shafts 44, 45 on which are also pinions 46, 47. Short racks 48, 49 on the bed engage the pinions 46, 47 during the reversal.
Patent GB-437665-A (GB)
Title: Improvements in or relating to actuating mechanism for mechanical stokers
IPC: F23K3/16
Filed: 1934-05-04
Abstract: 437,665. Mechanical stokers. WECK, E. A., Greiz, Thuringia, Germany. May 4, 1934, No. 13499. [Class 51 (i)] In a mechanical stoker of the oscillating- shovel type, the cam for actuating the shovel shaft to tension the springs is so shaped as to impart to the shovel a reciprocating movement immediately before the fuel throwing stroke. The fuel deposited in front of the shovel is thus moved forward before being subjected to impact throws by the shovel and where the grate is exceptionally wide the fuel is scattered laterally. For grates of normal width only one or two of a sequence of throws are impact throws. The actuating gear shown in Figs. 5 and 6 is adapted for imparting to the fuel two impact throws in a series of eight throws by the shovel. A continuously driven disc 6 carries a pivoted cam 4 which engages a roller 11 on an arm 10 secured to one end of a shovel shaft, the other end of which is provided with tensioning springs. The cam 4 is adapted to engage one of a number of radially adjustable abutments 5, 5<a> for varying the position of the cam to vary the length of the shovel throws. These abutments are mounted on a disc 5b which is normally coupled to the disc 6 by pins 68 but is intermittently uncoupled and moved relatively to the disc 6 through an angular distance equal to the distance between two adjacent abutments and then again coupled to the disc 6 so as to bring the abutments successively into engagement with the cam 4. This is effected by a cam 61<a> on the disc 6 engaging with a roller 65 on a sleeve 63 which is moved towards the right against a spring 63<a> and by means of a projection 64 engaging with a groove in the disc 5b uncouples the latter from the disc 6. The disc 5b is brought to rest by a stop 67 and when the cam 61a releases the roller 65 the spring 63a effects the movement of the sleeve 63 and disc 5b towards the left and coupling of the two discs. Reciprocation of the shovel immediately before the impact stroke is effected by a groove 7 in the cam. Pivoted members 8 on the cam 4 are adapted to be engaged by the longer abutments 5 so as to prevent the roller entering the groove 7 when the fuel throwing strokes are other than impact strokes. The shorter abutments 5a do not engage the members 8. Where the shovel strokes are all impact strokes the member 8 is dispensed with and all the abutments 5, 5<a> are of the same length. The nose of the shovel may have a central inwardly curved surface flanked by backwardly inclined surfaces.

Title: Apparatus for measuring grain losses in threshing machines, particularly harvester-threshers
IPC: A01D41/127
Filed: 1969-03-14
Abstract: 1,261,235. Grain loss measurement in a combine harvester. DEERE & CO. 14 March, 1969 [15 March, 1968], No. 13571/69. Heading A1F. Grain loss measuring apparatus in a combine harvester which has a straw shaker, a short straw sieve and a receiving device for the grains to be measured comprises a pressure responsive sensing device operated by the amount of grain passing a specific point per unit time. The sensing device may be arranged to measure the grain loss at the straw shaker or the short straw sieve and comprises a blower 76 and a co-operating pressure gauge 78. The sensing device may be arranged to automatically regulate the speed of the combine and, if desired, the operation of a blower which co-operates with the shaker or the sieve, or merely to provide a visible or audible signal to the harvester operator. Where the sensing means is to be used in conjunction with the shaker 12 an aperture 20 is provided extending across the whole width of the shaker which collects the grain passing through at that point and delivers it via a worm 24 to the sensing device 70. The worm may be replaced by an angled plate or the device 70 may extend across the full width of the combine. Where the sensing device is to be used in conjunction with the sieve three worms are positioned at the end of the sieve each feeding a sensing device. Two of the sensing devices are used to control the sieve apertures and the sieve blower with the third controlling both. When the apertures are enlarged the harvester's chaff worms may become overfull so a further measuring device is provided and the outputs of all the devices are fed to a computer. The sensing device 70, Fig. 3, has a suction blower 74 for removing chaff. The pressure gauge 78 registers a reading dependent on the degree to which the air flow from the blower is disturbed by the grain flow. In a modification the blower 76 is directed up the grain channel from one side and the pressure gauge is located someway up the channel at the other side so that the air flow sweeps the whole of the cross section of the channel.
