Title: Improvements in apparatus for feeding and separating semi-stiff sheets such as pieces of mail
IPC: B65H5/10
Filed: 1960-04-21
Abstract: 891,684. Feeding sheets. PITNEY-BOWES Inc. April 21, 1960 [May 4, 1959], No.14011/60. Class 100(1) Apparatus for feeding and separating semistiff sheets such as pieces of mail, includes a conveyer for moving a stack of sheets to a stop position, a vacuum cup which separates the foremost sheet and moves it to a position where it is transferred to a further vacuum cup which passes the sheet into a shoot, and two rotatable friction wheels arranged within the shoot in such manner that if two sheets are passed together to the shoot, the sheets are separated in opposite directions. Pile supports:-The sheets or pieces of mail are supported in a stack on a table 4 at an angle of 45 degrees to the vertical, and are fed towards a front,lip 6 over an inclined ramp 4a by endless belts 1. The belts 1 are driven by a motor 2a whenever a light source 3 is not prevented by the front sheets of the stack from impinging on a photoelectric cell 2. Registering sheets:-The front sheets of the pile are moved sidewise against a reference plate 7 by a driven cross-belt 5 which assumes an L-shape as it passes over the inclined front lip 6 of the table. Sheet separators and forwarders:-Sheets are separated sequentially from the stack by a vacuum cup 8 oscillating about the axis of a shaft 9 through approximately 180 degrees, and they are then grasped at their opposite faces by a further vacuum cup 10 which oscillates through more than 180 degrees about the axis of a shaft 11. The sheets are released by the cup 10 to fall into a shoot 17, and are carried away by a belt 21. The vacuum cups 8, 10 are oscillated about axes 9, 11 by a slow-speed motor 30, crank arm 31, gearing and belt-and-pulley means. The motor also drives contactor discs 32 which control three-way valves 12, 13 in the vacuum pipes. If two or more overlapping sheets are separated by the cup 8, the cup 10 will only grasp one sheet and the rest will fall into a receptacle 14. Double separation is also eliminated by arranging the cups 8, 10 so that they do not meet face to face, and the cup 10 can be arranged to rock on a pivot, against the action of a spring, on meeting the cup 8. The cups can be made entirely of soft rubber-like material, or have distortable rims, and are curved to distort the sheets. Detecting faulty separation:-When each sheet falls into the shoot 17, it lies between two friction wheels 15 which are each driven in the same direction by a motor 18, and one wheel is rocked towards the other by a solenoid 19 controlled by a contactor disc 32 on the shaft of the motor 30. if two sheets have been separated together and have been forwarded by the vacuum cup 10, the wheels 15 separate them in opposite directions so that they cover two spaced holes 16 in the shoot 17: this cuts off light passing through both the holes 16 on to photo-cells, and relays are actuated to cause a solenoid to move a gate within the shoot 17 to divert one or both sheets into a reject container.

Filed: 1935-05-16
Abstract: 457,094. Reversing-gearing. LANGDON, A. G., 77, Derby Road, Northam, Southampton. May 16, 1935, No. 14398. [Class 80 (ii)] In planetary bevel reversing-gearing suitable for marine use, a carrier disc 18, Figs. 1 and 2, for the intermediate or planet gears 25 is adapted to float axially independently of these gears so that it can transmit through it from face to face the thrust of a forward-driving clutch. Fast on the driving-shaft 1 is a driving plate 2 to which is secured a driving bevel wheel 3. Fast on the aligned driven shaft 5 is a driven bevel wheel 12 upon which is splined and held by a nut 14 a driven plate 13. The wheels 12, 3 are kept from separating by a thrust bearing 8 shouldered within the wheel 3, and these wheels hold between them shoes 22, Fig. 4, of separate studs 23 each of which supports are intermediate gear 25 held properly in mesh with the wheels 3, 12. The carrier disc 18 is formed with through apertures 16<1>, Fig. 2, to receive the gears 25 and has a central hub 15 with axial slots 21 to accommodate the shoes 22. Over the apertures 16<1> are flanges 17 with axial guide slots 20, Fig. 1, each to accommodate a square nut 24 on its stud 23. The carrier disc 18 can thus slide axially leaving the studs 23 clamped between the wheels 3, 12. The carrier 18 has an outer drum 19 adapted to be engaged by a brake 39 to effect reversed driving. There are two sets of clutch plates for forward driving, one on each side of the carrier 18. One set 26 connects a flange 27 on the driving plate 2 to the adjacent flanged part 17 on the carrier. The other set 26<1> connects a flange 28 on the driven plate 13 to the other flanged part 17 of the carrier. This double solid-driving clutch is applied by sliding right of Fig. 1 a rack sleeve 35 operated by the same lever 38 which applies the brake 39. Racks 36 turn toothed sectors 34 pivoted upon lugs 33 on the plate 13. The sectors 34 by cams 31 thrust inwards pins 29 which act on the clutch discs 26 through a cam expanding washer 30. The reaction of the cams 31 is a leftward thrust on the nut 14 which is passed on through an extension of the shaft 5, through the bearing 8 to the plate 2 and through the plates 26 to the carrier 18 where it meets the thrust of the pins 29.

Title: Improvements in radiometric analysis
Inventor: STARNES PETER EDWARD
IPC: G01N23/223
Filed: 1964-04-08
Abstract: 1,103,562. Radiometric analysis. HILGER & WATTS Ltd. April 5, 1965 [April 8, 1964], No. 14580/64. Heading G1A. When carrying out continuous radiometric analysis of a slurry, constituents are identified by the characteristic radiation excited by radiation from a radio-active source, quantitative results being obtained by measuring also the density of the slurry in terms of the absorption of radiation from a second source. As shown, slurry is fed at 16 to a constant level device 14 and thence to a tank 2 evacuated by a pump 15. The slurry is agitated by paddles 3, 33 and fed by a pump 5 through a chamber 9 where a detector 10 measures the absorption of radiation from a source 8 in the 600-3000 keV range, such as caesium 137. The slurry then passes through a sample cell 11 where the secondary radiation excited by radiation from a source 12 is measured by a detector 13. Alternatively the transmitted primary and secondary radiations may be measured together. Depending on the sample under investigation, the source 12 may be iron 55, tritium, helium 3, strontium 85, cadmium 109, promethium 147 or americium 241'. In the cell 12 the sample passes in a thin layer between a rigid wall and a flexible adjustable wall. The velocity of flow can thereby be adjusted. By imparting an acceleration to the sample a compensation can be effected for the relatively less effective sensitivity to radiation of the larger slurry particles since they are also less accelerated and remain longer in the irration field.

Title: Improvements in or relating to Solute Concentration Measurement
Inventor: SIMON WILHELM
IPC: G01N25/48
Filed: 1965-04-06
Abstract: 1,151,501. Determining the molar concentration of solutions, electrically. PERKINELMER Ltd. July 6, 1966 [April 6, 1965], No.14609/65. Heading G1N. The molar concentration or molecular weight of a solution is monitored by observing the change in resistance of a semi-conductor bead thermistor 39 as the solution flows from an outlet 37 of a tube 27 over the bead surface in the form of a film, which solution may be effluent from a chromatograph column (not shown). The bead resistance may be compared in a bridge with a fixed reference resistance, or alternatively with the resistance of a reference bead 41 over which a carrier liquid or solvent, as used in the column, flows in the form of a film from an outlet 38 of a tube 28. The vertical separation of the respective outlets and beads is adjustable to produce the films. The thermistor sensors are contained in an isopiestic chamber 19 (i.e. a chamber containing a constant vapour pressure of solvent) on the base of which is a pool 50 of solvent similar to that used as the carrier in the column. Over-flow funnels 40, 44 prevent contamination of the pool by the effluent. The inner surface 17 of the chamber is lined with absorbent material to assist evaporation of the solvent. Operation The chamber is within a thermally insulating casing 1, 2 which is temperature controlled and in operation is heated by an electric heater 7, air being circulated by a fan 10, until steady state temperature conditions are reached and the pressure of evaporated solvent remains constant which in general is when the chamber is saturated with solvent. The resistance of the beads will then be stable. The flow of the effluent solution and solvent over the thermistors is then commenced. Since the effluent comprises the solvent and traces of a sample under analysis it will have a lower vapour pressure than the solvent, dependent on the quantity and molecular weight of the sample constituents; which results in condensation of solvent vapour on the effluent surface whose temperature then increases. This increase is detected by the bead 39 and upsets the balance of a constant voltage input D.C. bridge. Equilibrium is reached when the vapour pressures of the effluent and solvent become equal, and the temperature difference which then exists indicates the molar concentration of the sample constituents on the bead 39 at that time. By adjusting the bridge until balanced a record of temp. difference is obtained or alternatively the bridge output may be connected to a chart recorder. The refractive index of the effluent may also be detected, and is dependent on density, also the molecular weights at various peaks can be derived by correlation of the reading of total mass and total number of moles. The arrangement may be used to compare two liquids.
