Abstract: 386,361. Multiplying and dividing apparatus. GORBATCHEVSKY, A., 4, Rue Duffaut, Clamart, Seine, France. Sept. 9, 1931, No. 25283. [Class 106 (i).] Apparatus for the four rules comprises cylinders geared together in pairs and bearing the products of digits, the cylinders being mounted in a frame movable in two directions at right -angles. Stylus-operated adding and subtracting mechanism is also provided. The drums 20, 21 are arranged in pairs and geared together one drum of each pair bearing the units and the other the tens of the digit products. The drums are mounted in a casing 11 which can slide longitudinally on a frame 9 which can itself move forwardly and rearwardly so that any row of drum figures can be brought beneath windows 29 in a fixed bar. This latter movement is effected by turning a knob 3 connected to rack-and-pinion gearing 8, 7, the row of drum figures below the opening being indicated by a wheel 4. The partial products are summed by entering them in a stylusoperated adding and subtracting mechanism contained in a casing 30, which may be bodily removed from the apparatus. The drum casing 11 is moved along the frame 9 by a handle 13 to bring the figures in the windows 29 adjacent the proper adding wheels as the various partial products are obtained. The adding and subtracting mechanism comprises discs 43 situated beneath arcuate slots 38 around which are inscribed two sets of numerals, the outer set being used in addition and the inner in subtraction. The discs 43 are geared to numeral discs 41 on the spindles of which are secured mutilated pinions 49 co-operating with a rackbar 50 to form a zeroizing device. Transfer is effected by teeth 45 in the discs 43 adapted to actuate the higher discs 41 once in each revolution. Rules are given in the Specification whereby the device may be used for division.

Abstract: A synthetic crystalline zeolite molecular sieve, designated zeolite Q, of general formula: 0,95\sB0,05M2/nO:Al2O3: 2,2\sB0,5SiO2: O-5H2O, where M is a Group I or II metal of valency n, or a hydrogen or ammonium ion, and having a specified characteristic X-ray diffraction pattern, is prepared, initially in the potassium form, from an aqueous reactant solution having the following oxide mole ratios: K2O/SiO2 of 4, SiO2/Al2O3 of 4, H2O/K2O of 12 by maintaining such solution at 25 to 50 DEG C. until the zeolite crystallizes.  The potassium form may be connected to the other forms, e.g. the Na, Li, Ba, Ca, Mg, Sr, or Zn form by ion exchange.  Suitable sources of silica for the initial reactant solution are silica gel, silica acid and potassium sibiate: sources of alumina may be activated, alpha or gamma alumina, alumina trihydrate or hydroxide or potassium aluminate.  Potassium hydroxide may supply the potassium ion.  The formed zeolite is preferably washed with water until the wash water has a pH of 9 to 12.  The zeolite crystals are activated by heating to about 130 DEG C. optionally under reduced pressure, or by applying vacuum at room temperature.  The so-activated zeolite may be employed as an adsorbent for water, carbon dioxide, ammonia and sulphur dioxide whereby these components may be separated from nitrogen, oxygen, argon, ethane, ethylene or propylene.  The zeolite may be pelletted with clay.

Title: Improvements in conveyors more particularly intended for laundry and like use
IPC: D06F67/00
Filed: 1930-12-31
Abstract: 363,150. Ironing-machines ; endless chain conveyers. BRITISH-AMERICAN LAUNDRY MACHINERY CO., Ltd., Underhill Street, London.-(American Laundry Machinery Co. ; Norwood Station, Cincinnati, Ohio, U.S.A.) Dec. 31, 1930, No. 39284. [Class 138 (ii).] The delivery end of an ironing machine is provided with an intermittently moved endless conveyer on to which the goods are delivered during the times that the conveyer is stationary. The conveyer is started by the actuation of a trip mechanism and after being moved through a predetermined distance is again stopped, the goods of one customer being kept separate from those of another by this arrangement. The trip mechanism may be actuated by the operator or by the passage of a certain piece of goods through the machine. The conveyer comprises overlapping plates 18 pivoted at one edge to side chains 19 and provided with a diverging supporting track 20 for the free edges of the plates which prevents any noise being caused by the falling plates and permits them to assume the final vertical position before passing back to the upper lap. Certain of the plates are provided with upstanding portions 17 which define coinpartments for the goods of different customers, the travel of the conveyer between the intermittent rest periods being equal to the distance between two partitions 17. A constantly running disc 25 having four axiallyprojecting pins 26 is loosely mounted on a shaft 13 on which another disc 24 anc. the sprocket wheels driving the conveyer are secured. A bellcrank lever 22 is pivoted at 23 on the disc 24 and is normally held against the force of a spring 29 and with its shorter arm out of the path of the pins 26 by an arm 30 pivoted to the frame of the conveyer, whereby the drive is not transmitted from the disc 25 to the shaft 13. A roller 11 is carried by arms 9 (ne of which is free to rise and is linked at 32 to the arm 30. When the last article of a particular customer has been fed to the machine a thick pad is fed thereto and on emerging raises the arm 9 thereby swinging the arm 30 out of contact with the bell-crank lever 22 so that the latter is swung by the spring 29 clockwise. The drive is thereby transmitted to the conveyer and continues until the arm 9 drops which takes place after the shaft 13 has been rotated one revolution and the conveyer advanced by the distance between two partitions 17. A knob 38 is also linked to the arm 30 so that the transmission of the drive to the conveyer may be controlled by the operator. An alternative control by the operator comprises a fluid-pressure piston and cylinder device acting on the lever 9.

Filed: 1966-09-06
Abstract: 1,112,328. Unpacking. GEO. J. MEYER MANUFACTURING CO. 6 Sept., 1966 [14 Sept. 1965], No. 39736/66. Headings B8A and B8C. In order to facilitate the opening of the leading flap of a rectangular carton box 6 travelling on a conveyer belt of apparatus for emptying the carton, the carton is rotated through 180 degrees so that the aforementioned flap becomes the trailing flap. Flap opening.-Flap opening means include a plough 7 which opens the side flaps 8, 9 when the carton is travelling on input conveyer 3, Fig. 2. Hook means 11 open the trailing flap (12), (see also Fig. 3, not shown), and the carton is then discharged to a further conveyer 13 moving faster than conveyer 3 and hence causing cartons to separate. The reversing means (see also Figs. 4, 5, not shown), includes a pivoted arm 16 having a foot 18 and stop plate 19 and adapted to engage a corner of the carton. An endless belt 20 engages the side of the carton and cooperates with the arm 16 to rotate it. To align the carton correctly, a guide roller 25 may complete the rotary operation. A pulley 23 of belt 20 is resiliently mounted so that run 24 of the belt may yield under pressure from the carton corners. To open the now trailing flap, (see also Figs. 6, 7, 8, not shown), a shoe 34 and hook 39 are provided, the edge 35 of the shoe riding over the now open leading flap (12) and over the carton contents, the hook 39 subsequently opening the now trailing flap (26). Dumping the contents.-The carton is inverted by passing round a drum 41 (see also Fig. 9, not shown), carrying a pair of pneumatic tyres 42, (43), the carton being held against the drum by a driven belt 44 running on rollers 45 . . . 49, a resiliently mounted roller 50 being arranged to take up any slack in belt 44. At the upper end of drum 41 (see also Figs. 10, 11, not shown), a support plate 51 receives the carton which then passes over support wires between which the contents drop, the wires retaining any partition elements. The contents, e.g. cans, fall on to a conveyer 52 to be discharged. At the sides of support plate 51 are positioned guides (55), (56) carrying driven belts (155), (156) engaging the side flaps 8, 9, rollers 157 also being provided to force said flaps against the belts and hence drive the carton along. Driven knocker arms (not shown) may be provided to strike the side flaps and aid in contents release. Finally, the empty cartons are engaged between the opposed side walls of a spaced pair of pneumatic inner tubes 59, (60), (see also Fig. 13, not shown), which invert them and deliver them to a discharge conveyer 61. Fig. 12 (not shown), illustrates a method of discharging separately two layers of cans. A support plate analogous to 51 and wires guide the carton, the then bottom layer falling on to a conveyer. The carton moves over the wires (70a) on to a further support plate which prevents the second layer falling out until it can fall between wires on to a further conveyer or shoot.
