Patent GB-935011-A (GB)
Title: Improvements in batch weighing machines
Inventor: MERSH HAROLD CHARLES
IPC: G01G13/00
Filed: 1958-11-06
Abstract: 935,011. Automatic feed weighers. EASTERN GAS BOARD. Jan. 5, 1960 [Nov. 6, 1958], No. 35688/58. Class 143. A coke weigher, in which the feed to a weigh hopper 10 is by an inclined shoot 2 vibrated by a motor 3 and closable at its lower end by an upwardly swing- ing gate 18, is so controlled that the feed automatically stops when a predetermined weight has been dispensed and cannot be restarted until this load has been discharged and the weigh hopper's discharge gate 12 reclosed. Preferably the base of the shoot 2 is perforated so that undersize coke will pass into a reject hopper 6. Gate 18 is opened by a solenoid-operated fluid pressure ram 25 and closed by a counter-weight 22, but may be latched open by means contained in holding unit 32. This means comprises a lever 39 pivoted at one end to the arms 33 which support the gate and having at the other end a depression 40, Fig. 3, which is engaged by the free end of a pivoted lever 41 when the gate 18 is fully open. Discharge gate 12 is fully controlled by a ram 34. The whole apparatus is controlled by electrical relays (Fig. 5, not shown) whereby the following sequence of operations is ensured. Provided the hopper 10 is unloaded and its gate 12 closed, actuation of a push-button switch starts motor 3 and operates ram 25 to open the gate. When the gate is fully open the movement of lever 41, Fig. 3, into its latching position causes a cam 48 on this lever to act on a microswitch 49 and de-energize the solenoid of ram 25, which returns to its initial position. When the hopper 10 is nearly fully charged, a contact in the weigher 13 energizes a solenoid 43, Fig. 3, by which pivoted lever 41 is released from its engagement with arm 39, so that the feed gate closes. This closure takes place against the resistance of a dashpot 29, Fig. 2 (not shown), and the operation is adjusted so that final closure of the gate occurs when the precise required load has been fed. A switch operated by the closing gate also stops motor 3. A foot switch 38, Fig. 1, will discharge the load by opening gate 12, but is effective only if feed gate 18 has completely closed. Reclosure of discharge gate 12 may be made to effect automatic restarting of the feed.

Title: Improvements relating to luminescent display apparatus
IPC: H01J29/18
Filed: 1954-12-10
Abstract: 788,165. Cathode-ray tubes. GENERAL ELECTRIC CO. Dec. 10, 1954 [Dec. 29; 1953], No. 35844/54. Class 39(1). [Also in Group XL(c)] Reflection of external light from the face of a cathode-ray tube is minimized by using a transparent continuous specularly-reflecting luminescent film of the kind described in Specifications 702,575 and 711,015 and superimposing an anti-reflection filter between this film and the external source. Halation effects are also reduced. The film 12 is deposited on the inside of the optically-polished tube face 10 and may itself be optically polished after deposition and backed by metal film 16. The filter comprises polarizing layer 21 and quarter-wave retardation plate 22. Light F from source 23 is, say, vertically polarized in 21 and circularly polarized in 22. Any reflected light G is turned away by tilting the filter downwards. The circularlypolarized light A strikes the tube face and is specularly reflected at the three interfaces without change of polarization as rays H, I, J. The plate 22 now converts the circular polarization into horizontal polarization which is rejected by layer 21. The filter 21, 22 may be mounted separately in a window in the cabinet E, Fig. 3 (not shown) or on the cathode-ray tube by an annular collar, Fig. 5 (not shown) or cemented to the outer face of the tube itself by a plastic cement of similar refractive index, Fig. 4 (not shown).

Title: Improvements in or relating to engine starter drives
IPC: F02N15/02
Filed: 1938-12-19
Abstract: 522,839. Turning-gear. BENDIX AVIATION CORPORATION. Dec. 19, 1938, No. 36922. Convention date, Dec. 24, 1937. [Class 7 (v)] In an engine starter including a pinion 4 movable into and out of mesh with a member 5 of the engine to be started, the pinion is drivably connected to the starting-motor shaft 2 through a cam connection 17, 18 which causes indexing of the pinion when its longitudinal movement is obstructed and through a friction clutch 8, 16, the cam connection and clutch being rendered effective to transmit cranking torque to the pinion upon rotation of the shaft. As shown in Figs. 1 and 3, a sleeve 7 splined on the shaft 2 has a clutch flange 8 formed or fixed thereon and is externally threaded to engage a shifting member 14. A flange 9 is rigidly mounted on the pinion 4 and a barrel 11 loosely mounted on the flanges 8, 9 is provided with a thrust collar 12 and lock ring 13 and is rigidly connected to a flange 15 on the member 14. An annular clutch plate 16 is loosely mounted between the flanges 8, 9, and cam elements 17, 18 are provided on the members 9, 16, which are normally held in extended relation by a torsion spring 19. The shifting member 14 is actuated by a fork 27 connected by a link 31 to the plunger 29 of a solenoid 28, which may also close a switch for the starting motor when the pinion 4 is in mesh with the engine member 5. The initial rotation of the motor causes the sleeve 7 to thread itself forward in the member 14, compressing the cam connection 17, 18 and building up pressure in the clutch 8, 16. If the pinion teeth clash with those of the member 5, continued axial movement of the member 16 causes the pinion to be turned into meshing position by the action of the inclined surfaces 23, 24. When the engine starts, the clutch pressure is relieved by the threaded connection. A modification is described in which the meshing movement of the starter pinion is towards the starting motor and is effected by a lever actuated through a cable actuated manually or by electric or mechanical means ; a light friction spring coiled on one of the friction-clutch members ensures the initial engagement of these members.

Filed: 1970-08-05
Abstract: 1358839 Chlorine monoxide PULP & PAPER RESEARCH INSTITUTE OF CANADA 28 July 1971 [5 Aug 1970] 37803/70 Heading C1A Chlorine monoxide is prepared by reacting a highly reactive porous form of a solid alkaline reacting salt of an alkali metal having a surface area within the range 1À0 to 1000 m.<SP>2</SP>/g. with a moist mixture of chlorine and a diluent gas, the chlorine being dry and in substantially stoichiometric amount and the diluent gas being moist air, oxygen, nitrogen or a mixture thereof at a temperature of - 20‹ to + 30‹ C. and removing the chlorine monoxide formed either as a gas or as a solution in carbon tetrachloride. The preferred salt is sodium carbonate which may be prepared by carbonating an aqueous green liquor from the wash water of pulp bleaching operations and containing Na 2 S and Na 2 CO 3  together with minor amounts of Na 2 S 2 O 3 , Na 2 SO 3  and Na 2 SO 4 , drying and pulverizing the so-formed slurry of NaHCO 3  and heating the dried product at 150-300‹ C. Other salts specified include sodium bicarbonate, sodium sesquicarbonate, potassium and lithium carbonates, bicarbonates and sesquicarbonates, sodium and potassium phosphates and sodium and potassium silicates. The salt may be used in stoichiometric or excess amounts. The diluent gas (air, O 2  or N 2 ) should be used in an amount such as to provide a diluent/Cl 2  ratio of at least 77/23 v./v. Ions such as Ni, Co or Cu should not be present as impurities in the alkaline reacting salt since their presence leads to formation of oxygen instead of Cl 2 O. The process may be carried out batchwise or continuously, and it may be associated with a pulp bleaching process. As shown in Fig. 3, dried and ground NaHCO 3  is fed into a fluidized bed calciner 100 where it is heated by a stream of hot CO 2  and H 2 O, the hot gas stream being that evolved by the decomposition of the bicarbonate, heated in a heater 104 and recirculated as fluidizing gas. The porous Na 2 CO 3  is passed to a cooler 108 where it is cooled by air stream 109. The cooled carbonate passes to reactor 112 at a temperature of 150‹ to 500‹ C. where it is fluidized by a stream of gas in line 119, the said stream comprising a mixture of chlorine 113 which is dried at 114 and diluent air, O 2  or N 2  116 the relative humidity of which is controlled between 5% and 95% by apparatus 114. The solid reaction product comprising NaCl with traces of NaClO 3 , Na 2 CO 3  and NaHCO 3  is withdrawn at 120, the gaseous product comprising Cl 2 O, CO 2  and diluent gas passing via line 122 directly to a pulp bleaching reactor 121.

Abstract: 912,613. Adjusting height of pneumatic spring suspensions. CLAYTON DEWANDRE CO. Ltd. March 2, 1960 [Dec. 2, 1958], No. 38861/58. Class 108(2). An air-spring (not shown) in a vehicle suspension system is maintained at a desired riding height by the operation of an hydraulically damped levelling valve 1 which lets air into or out of the air-spring when actuated by a prestressed spring 33 normally held inoperative at the desired riding position by a stop means which is displacable upon changes of the position due to relative movement between the vehicle chassis and the axle structure. A housing 3, bolted to the chassis, carries a lever 4 which connects the spool 15 of the valve 1 with the piston 20 of an hydraulic damper 2, also, by way of a pivot, with a telescopic assembly 5. In its downward position the spool 15 connects the airspring to the air supply by way of grooves 11 and 12 and channels 13 and 14 in the valve chamber sleeve 8 and the groove 16 on the spool. In its upward position the spool vents air from the spring by way of the groove 12, the ports 14, the groove 17, channels 18 and an air filter in an exhaust port 19. When the air-spring is at the desired height the spool is central and connects it with neither. The assembly 5 comprises concentric tubes 24 and 25 which are fixed to the lever 4 and which slide over a tube 28 bolted to the axle 6. A stop 30 on the tube 28 abuts a flange 31 on the lower end of a sleeve 32 slidable on the tube 25 which is kept by the springs 33 in abutment with the top tube 24 when the air spring is at the desired height. In this position the lower end of the spring also urges a thrust ring 34 against the bottom of the tube 28 and the head 36 of a rod 35 on the ring 34 rests on a stop 37 inside the tube 35. Relative movement between the chassis and the axle causes the assembly 5 to compress or to extend so that the spring 33 looses its support from the outer tubes at one end or the other, whereby it is caused to operate the valve 1 as has been previously described. Figs. 2 and 3 (not shown) illustrate respectively an embodiment in which the valve spool 5 is arranged integrally in alignment with the piston rod of the damper 3 in a common housing and an embodiment in which the damper and the valve system are arranged inside and coaxially with the assembly 5. In the latter instance the valve system comprises spring-loaded poppet valves situated on either side of a central actuating rod. Torsion springs may take the place of compression springs in any of the embodiments.
