Title: Improvements in or relating to an apparatus for counting bank notes and similar articles
IPC: G06M7/06
Filed: 1959-06-25
Abstract: 873,587. Photo-electric control arrangements. UCHIDA, I. June 25, 1959 [June 25, 1958], No. 21846/59. Class 40(3) [Also in Group XVI] Apparatus for counting bank-notes and like articles comprises a delivery device designed to feed the notes one at a time in spaced relationship past a photo-electric counting device and a receiving and stacking device for the counted notes. The apparatus rejects notes which overlap and gives a warning when notes pass the counting device without a space between them and thereby make the count inaccurate. The notes are stacked in an input position on conveyer 4 and are fed forward by the conveyer to pass over driven rollers 6 and under a set of levers 7 to feed roller 19 and pressing element 9. The coefficient of friction of the surface of drum 19 is arranged to be greater than that of pressing element 9 which is, in turn, greater than that of the notes to be counted. The coefficients may be in the ratios 3:2:1 although this is not critical. Rotation of the drum 19 serves to pass the notes forward substantially one at a time along a short conveyer 57 (or down a guide) to a further conveyer travelling at a higher speed than the peripheral speed of drum 19. This consists of pairs of upper and lower V-belts 21, 22 between which the notes pass the photo-electric arrangements in spaced-apart relationship. To reduce wear on the friction surfaces of drum 19 and element 9 one of the levers 7 includes a contact which touches a slip ring 6<SP>1</SP> on a roller 6 when the supply of notes is exhausted and completes the circuit of an electromagnet withdrawing presser element 9. A further electromagnet returns the element to the operative position when the lever slip-ring circuit is interrupted by further notes. Photo-electric devices perform three functions. Firstly the notes pass between a light source 27 and cell 29. If two overlapping notes pass the level of illumination is reduced to such an extent that a circuit is operated to prevent counting, direct the overlapping notes into a reject bin 41 by dropping fork 39, and stop the feed. Secondly photo cell 30 and co-operating light source 28 provides an impulse to the counter each time the illumination increases due to a gap between the notes. The count may be indicated on scales 32 and associated dials 73 may be preset with a desired count in which case at the correct count the machine is stopped and any extra notes passing through directed by fork 39 into bin 41. Thirdly a row of photo-cells greater in length than the length of one note is provided to avoid errors due to notes not being spaced apart as they pass the counting cell. If two notes not spaced apart cover all the cells in the row a warning is given and counting stopped. After the notes have passed the photo-electric devices they are passed by V-belts 34 to a box 35. The motor driving the belts 34 also vibrates a plate 72 by means of a cam to aid in stacking the notes.

Abstract: 1,056,115. Automatic backwash sand filter. KOPPERS CO. Inc. May 27, 1964 [June 5, 1963], No. 21991/64. Heading BID. In a sand filter, back washing is carried out by pumping filtered liquid back through ports 38 in the side wall 12 of the filter tank by means of a back washing shoe device 74 which slides along the outer surface of the wall engaging the ports 38 successively and which is suspended from a moving carriage 46 spring means 82 (Fig. 8) being provided for urging the shoe into close conformity with the wall surface to so prevent leakage. The shoe 74 is connected by conduits 68 to a pump 54, a pivoted arm 60 depending from the carriage supporting the shoe 74 by a chain 78 against vertical movement. The carriage also carries a hood 88 with a pump 94 therein which removes the upwardly flowing wash liquid and contaminant therein. The movement of the carriage commences when the accumulation of unfiltered liquid reaches level control 122, and the carriage then moves to and from over the sand bed 34 until the liquid level drops to control 128 which then stops the carriage when it next reaches one end of the tank. The filter bed is divided transverselly by dividers. A series of U-shaped scarifying means are carried by rods within the hood and agitate the bed to a uniform depth. The carriage movement is reversed when a switch carried by the carriage engages members on the side wall adjacent the ends of the wall. The switch is connected in a circuit of a control box 124 together with the controls 122 and 128, the control 128 when activated by drop of liquid level triggering the circuit and stopping the carriage at the wall end after the reverse switch has been tripped ready for recommencement.

[Also in Division GA] The speed of and distance travelled by a vehicle are indicated by a system in which pulses of a frequency dependent on the speed of the vehicle are converted to a pulsating D.C. signal for a speedometer and also fed to a storage circuit which, when a pre-set number of pulses has been received, causes a trigger circuit to conduct to actuate an odometer. As shown, the passage of magnetic projections 14, Fig. 2, on the vehicle drive shaft are sensed by a Hall effect device 16 whose pulsating output is amplified in a Schmitt trigger circuit including transistors J-1, J-2. Alternatively the projections may be sensed by a magnetic reed switch, Fig. 3 (not shown), the Schmitt trigger circuit being omitted. In both embodiments the pulses are then fed to a pulse shaping circuit including transistors J-3-J-4 producing a pulsating D. C. current for speedometer M and supplying pulses to charge a capacitor 80. When the voltage across the capacitor reaches the pre-set level, uni-directional transistor J-6 conducts causing transistor J-7 to conduct with the resulting energization of the solenoid 100 of the electromagnetic counter M-2 indicating the distance travelled.

Title: Improvements in or relating to the hydrogenation of acetylenic carbinols
Filed: 1957-07-16
Abstract: Ethylenic carbinols of general formula: <FORM:0810913/IV (b)/1> are obtained by hydrogenating acetylenic carbinols of general formula: <FORM:0810913/IV (b)/2> in which R1 and R2 each represent an hydrocarbon radical containing not more than 7 carbon atoms, in solution in 5 to 25 per cent of their weight of quinoline in the presence of a catalyst which selectively influences the hydrogenation of an acetylenic linkage to an ethylenic linkage.  Suitable acetylenic carbinol starting materials are, for example, 2-methyl-butyn(3)-ol(2), 3-methyl-pentyn(1)-ol(3), 3-ethylpentyn (1)-ol(3), 3.5-dimethyl-hexyn(1)-ol(3) and 2-phenyl-butyn-(3)-ol(2). The preferred catalyst is 5 per cent palladium on calcium carbonate, modified by deposition of lead. The hydrogenation is preferably carried out at temperatures in the range 0-25 DEG  C. and pressures not exceeding 5 p.s.i.g.  In the examples: (a) 2-methyl-butyn(3)-ol(2) in solution in quinoline is hydrogenated in the presence of a palladium on calcium carbonate catalyst modified by the deposition of lead to give 2-methyl-buten(3)-ol(2); (b) 3-methyl-pentyn(1)-ol(3) is hydrogenated similarly to give 3-methyl-penten(1)-ol(3); and (c) 3.5-dimethyl-hexyn(1)-ol(3) is similarly hydrogenated to give 3.5-dimethylhexen(1)-ol(3).

Abstract: 869,692. Valves. HYDRIL CO. July 1, 1959 [July 7, 1958], No. 22571/59. Class 135. [Also in Group XXI] A valve, incorporated in a string of oil-well drilling pipes, comprises a spherical plug 97 rotatable in horizontally aligned bearings in blocks 94, 95 which are slidable vertically into position in the body member 85 and are retained by the screwed-in body member 75. The bearing balls 98 run in annular races 100 cut in faces of the plug 97 and blocks 94, 95, spills 104, 105 revolving freely in holes in the blocks. The spill 105 has a diametral slot 110 which is vertical when the assembly 94, 95, 97 is slid axially into the body 85 and receives a diametral key 111 on a stem 112 which is socketed to receive a turning tool 115 whereby the plug 97 may be turned from the closed, Fig. 3, position to the open position in which the bore 127 is aligned with the bores 125, 80 of the drill pipe string. The spherical surface is sealed, top and bottom, by rings 92 which are pressed by rings 91 and leaf-springs 90, 124 against the said surface. The pressure is augmented by fluid pressure in the bores - 80, 125. In a modification, the rings 91, 92 are replaced by single shouldered rings and the leaf-springs act on the shoulders; an additional section is incorporated in the stem 112 to act as a universal coupling in case the body 97 is displaced axially of the drill pipe string by excess pressures; and the spill 104 is associated with a spring-pressed detent ball for indexing. Well pressure passing upwardly between the main casing 14, Fig. 1, and the tubing 15 acts upon the exterior of a rubber block 19 depending from a flange 20 and collapses the block about the tubing and prevents upward extrusion of a sealing lip 21. A blow-out preventer 11 in the string comprises a plastic annulus 31 with metal antiextension inserts 32 and a piston 28 with a tapered surface 29 for facing the annulus against the tubing 15; the piston is actuated by connecting a fluid pressure supply across ports 39, 44.
