Title: Safe load indicators in jib cranes
Inventor: SAUNDERS FRANK STANLEY
IPC: B66C23/90
Filed: 1963-01-31
Abstract: 993,954. Safe load indicators for jib-cranes. WEIGHLOAD Ltd. Feb. 13, 1964 [Jan. 31, 1963; May 20, 1963], Nos. 4040/63 and 20000/63. Heading B8B. In a safe load indicator for a jib-crane a pointer 31, Fig. 2, is moved clockwise by a pressure cell constructed as described in Specification 564,287, which measures the load being lifted, and a pointer 53 indicates the safe load for any given working radius and is moved anticlockwise as the radius is increased by a slave jib 36. When the pointers come into coincidence contacts 34, 55, Fig. 4, abut and a lamp 56 is lit. If the safe load is exceeded and the pointers pass each other a further contact 35, Fig. 5, offset from the pointer 53, abuts a contact 57 and a bell rings. The hydrostatic pressure fed to the pointer 31 by the load cell can be adjusted by a screw so that different methods of reeving the load pulley can be accommodated. The slave jib 36, Fig. 2, turns the pointer 53 through an arm 39 and an adjustable slide block 40 which can be adjusted for different jib lengths. The slide block 40 moves a slide 43 up and down and the latter carries a roller 45 which rotates an arm 47 about a pivot 48. This turns gear wheels 49, 50, 51 and the pointer 53.

Title: An improved rotary filter
IPC: B01D33/00
Filed: 1921-02-04
Abstract: 176,619. Johnson, R. M., and Hurrell, G. C. Feb. 4, 1921. Rotary filters. - Rotary suction filters are arranged to make several revolutions during the completion of the cycle of operations, comprising the formation of the cake and the drying, washing, steaming, dyeing, or impregnation, and removal, one or more revolutions being allowed for each individual operation. The periods of the several operations are controlled by a series of cams on a slowly rotating shaft M which may be driven from the shaft of the strainer by worm gearing I, Fig. 2, or by a train of pinions and spur-wheels, Fig. 4, or by equivalent arrangements. The filtration period may be brought to an end by a lever engaging one of the cams, which opens a by-pass from a pan R, so that the level therein of material to be filtered falls below the lower edge of the filter drum. Alternatively, a hinged or movable pan R may be used, or the drum may be raised out of contact with the sludge, or the supply of sludge may be cut off. To prevent cracks from forming during the drying of the cake, a squeegee S, Fig. 4, may be brought into contact with the cake during the collection of the cake or the early stages of drying by a lever and cam. Other cams and levers bring into operation, when desired, a compression roller T and a scraper W, and control the various valves for the vacuum and for the treating fluids. By varying the gearing for driving the shaft M and by changing the cams used, the periods of each of the successive operations can be regulated as required. As shown in Fig. 2, the filter is supported at one end on a solid shaft B and at the other on a hollow shaft C, through which passes a suction pipe E having depending branches F inside the filter. The drum shown in Fig. 5 has lips or pockets X which lift the filtered liquid and discharge it into a catchpan Y formed as part of a closed cylinder Z and with which the suction branches F communicate. The cylinder Z, by limiting the air space within the filter, facilitates the production of the partial vacuum required for filtration. The filter drum is preferably provided with the permeable covering described in Specification 174,116.

IPC: B65H3/08
Filed: 1950-02-17
Abstract: 692,034. Feeding sheets. BACKHOUSE, H. T. Feb. 19, 1951 [Feb. 17, 1950; Nov. 30, 1950], Nos. 4181/50 and 29400/50. Class 100(i) In apparatus for separating sheets from a pile 2 and forwarding them by further suckers 3 towards a conveyer 4, the suckers 3 are carried by tubes 6 secured to a transverse shaft 7 which is rocked by means of a. cam 11 acting through a rod 10 which is connected to the shaft 7 in such a way that the amount of movement of the suckers 3 can be varied during the operation of the apparatus. As shown in Fig. 1, the rod 10 is pivoted at 15 to a lever 14 the other end of which is connected to a screw 16 passing radially through the shaft 7, and an operating arm 9 is secured to the shaft 7 and pivoted to the lever 14. Rotation of the screw 16 rocks the link 14 about its connection to the arm 9, and varies the radial distance of the pivot 15 from the shaft 7, so that the angular movement of the shaft 7 is varied. In Fig. 2 the end of the rod 10 is guided in the curved slot of a lever 22 pivoted at one end 23 to the frame 24, and pivoted at the other end to a nut 25a on a screw 25 passing through a boss on the frame. A slider block 20 on the end of the rod 10 engages a slot 21 in an operating arm 9a secured to the shaft 7 to rock the latter, and by adjusting the nut 25a the position of the block 20 relative to the axis of the shaft 7 can be varied. In another modification, instead of the shaft 7, there are two co-axial shafts, each having a tube 6 secured thereto. One shaft is rocked directly from a push rod 10, and the other shaft is driven from the first shaft through an adjustable connection, whereby the movement of the second tube 6 and sucker 3 can be varied relative to the first. In a further modification, two co-axial shafts are also used, each rocked by a separate push rod 10 through adjustable means, whereby the rocking movements of each tube 6 can be varied. Specifications 427,041, 475,892 and 489,405 are referred to.

Title: Improvements in visibile index filing devices
IPC: B42F17/18
Filed: 1947-02-13
Abstract: 648,963. Filing devices. REMINGTON RAND, Ltd., and JACKSON, A. R. Feb. 13, 1947, No. 4192. [Class 146 (i)] In a visible index device of the kind employing overlapping separator leaves 21 as described in Specification 270,261, [Class 146 (i)], the leaves are secured to a carrier comprising an inclined leaf-mounting plate 13 hingedly secured to a panel 11 by a link 14, such that each leaf can extend substantially flat and straight throughout its length as shown in Fig. 3. The leaf mounting plate 13 has side channels 15 which accommodate projecting lugs of stiffening and spacing elements 22 of the leaves 21. The lugs are engaged in the channels 15 by flexing each leaf individually to bow its stiffening element. When the channels have been filled with lugs the leaf mounting plate 13 is swung into a position such that the outermost stiffening element engages a cross member 12 secured to the panel and having offset ends 121 which slidably engage extensions of the channels 15. The plate 13 is locked so as to clamp the lugs between a retainer 20 and the member 12 by the end 17 of a flat spring 16 which engages a pair of projections 18 on the panel 11. If it is desired to decrease the number of leaves one or more spacer strips are supplied to fill the channels to the desired extent in order that the end 17 of the spring 16 will be maintained in positive engagement with the projections 18. In a modified construction the number of leaves may be varied to a limited extent without employing spacer strips. In this case the pair of projections 18 is replaced by a plurality of pairs of projections in the form of racks, or a rack element may be secured to the panel. In order to provide the greater movement of the plate 13 towards the member 12 necessary in this construction the distance between the upper edge 13<SP>1</SP> of the plate and the upper extremity of the channels 15 is increased. A series of carriers with attached leaves may be carried in a tray each carrier being arranged substantially vertically by supporting the carrier on notched racks, one at each side of the bottom of the tray, each notch of the rack being provided with a V-shaped entrance slot such that the carrier may be pivoted through an angle. To provide a V- shaped space between the carriers to open the pockets between the leaves the ends of the tray may be pivoted.

Abstract: 524,903. Steam power plant. SULZER FRERES SOC. ANON. Feb. 10, 1939, No. 4423. Convention date, July 2, 1938. [Class 110 (iii)] In a steam power plant comprising a steam generator 1 of the flow through type, a high pressure steam consumer 5, an intermediate superheater 7 and a low pressure steam consumer 9 in series, the high pressure steam consumer is byepassed by a pipe 13 having a liquid containing chamber 15 adapted to act not only as a water separator and desuperheater but also as a heat accumulator. The level of the water 14 which will dry or desuperheat the steam passing through it and give off steam when the pressure in the supply line 8 falls, is maintained by the pump 26 drawing from the feed tank 12. A valve 16 in the high pressure steam pipe 4 is controlled by a servo motor 17 influenced by the steam pressure and temperature in the pipe 4. The valve 16 opens with an increase and closes with a decrease of pressure in the pipe 4, but if the steam temperature is either too high or too low, the thermostat 22 operates to close the valve entirely. Then the valve 18 in the byepass 13, which is only pressure controlled by the servo motor 19, opens to allow the steam to pass through the chamber 15 to the low pressure steam consumer 9. Other low pressure steam consumers can be placed in parallel with the consumer 9.

Abstract: 1433084 Counting electric pulses ALMEX AB 30 Jan 1974 04423/74 Heading G4D A counting arrangement includes a matrix store 1 and has a plurality of address inputs A 1 -A 10 , control inputs 11, 12 and an output 7; if a signal pulse is applied to an address input only a respective number corresponding to that input is incremented by unity; if a signal pulse is applied to an address input and the control inputs the respective number is read out to the output in coded form. In the Figure an address input signal also triggers a pulse generator 4 via OR-gate 5 releasing a pulse #, which acts to transfer the addressed number from the store 1 to a 14-bit counter 2. If the control 12 is not marked the generator 4 also releases a pulse # 2 , shortly after # 1 , which increments counter 2, the count then being returned to the store. If control 12 is marked the # 2  pulse is suppressed and the number is not incremented but simply transferred to a 14-bit shift register 3. The register 3 is then shifted by clock pulses # 3  at 11 to read out the number to output 7. The arrangement may be applied to recording numbers of different tickets issued. When a particular ticket is issued a pulse is applied to one input A 1 -A 9 ; shortly after a pulse is also applied to A 10  which therefore records the total. Subsequently the arrangement is connected to a data processor which addresses each input in turn to read out the numbers and total which it compares; the memory is then cleared by a signal at 8. To prevent falsification the processor may load a number known only to itself into the total section of the memory. The circuit may be integrated, using a static CMOS memory (not shown).
