Title: A process for the production and purification of cobalt oxide
IPC: C01G51/04
Filed: 1954-11-10
Abstract: Cobalt is recovered as cobalt oxide from cobalt compounds specified below, containing at least one of the impurties zinc, sulphur and chlorine by heating in the presence of a reducing gas containing carbon monoxide and/or hydrogen at a temperature between 800 and 1500 DEG C.  Compounds which may be treated are basic cobalt chlorides, basic cobalt sulphates, cobalt hydroxide, cobalt oxide or mixtures thereof.  Suitable reducing gases are blast furnace gas, water gas, coke oven gas, coal gas, hydrogen, oil gas, and producer gas.  The supply of heat for obtaining and maintaining the temperature may be obtained by partially burning the reducing gas in which case the gases leaving the furnace must contain at least 3 per cent by volume of hydrogen or carbon monoxide or mixtures thereof; alternatively indirect heating may be employed.  In the preferred procedure cobalt hydroxide is first calcined to give cobalt oxide and such oxide is treated by the process of the invention preferably in a rotary furnace the outlet of which is maintained at 1150 to 1250 DEG C. According to examples (1) cobalt hydrate containing zinc, sulphur and chlorine impurties was calcined in a rotary furnace with a 7-1 mixture of blast furnace and water gas in the presence of combustion air such that 7 to 8 per cent of carbon monoxide was present in the exhaust gases.  The outlet temperature of the furnace was 1250 DEG C. and the zinc content was reduced from 16.7 per cent to 0.6 per cent. (2) Calcined cobalt oxide was heated at 1200 DEG C. in an electric muffle furnace in the presence of water gas at 1200 DEG C. thereby removing zinc, sulphur and chlorine contaminants.  (3) Cobalt oxide containing zinc, sulphur and chlorine impurities was directly heated to above 1100 DEG C. in a shaft furnace by means of a fuel gas containing carbon monoxide and hydrogen in the presence of air; the reaction temperature was maintained at about 1000 DEG C.  The purified cobalt oxide recovered is suitable for electric furnace treatment for recovery of metallic cobalt.

Title: Control system
IPC: G05D23/22
Filed: 1962-08-24
Abstract: 956,745. Valve relay circuits. LEEDS & NORTHRUP CO. Aug. 24, 1962 [Sept. 1, 1961], No. 32616/62. Heading H3P. [Also in Division G3] A circuit for providing cyclic pulses of predetermined duration and repetition frequency comprises a pair of electronic discharge devices each having an electromagnetic relay in its output circuit, and a resistance-capacitance network connected in its control circuit by way of contacts of the relay associated with the other device, the arrangement being such that when either device is non-conducting the capacitance associated with the other device is connected to a charging circuit, and when either device is conducting the charged capacitance associated with the other device is connected to the control circuit of that device to hold it non-conducting. As described, the circuit is used with a control system of the type disclosed in Specification 850,940, [Group XXXV], to give " bumpless " transfer and is brought into use when manual control is required, by switching the gauged switch S from the position shown, to one of its other positions. Initially capacitor bank 56 is charged and capacitor bank 64 is discharged so that, on switching to manual control, valve 46 conducts, energizing relay 14 and closing contacts 14b to connect the charged capacitor bank 56 to the grid of valve 45 thus cutting it off. Capacitor bank 64 is meanwhile charged from supply 55 via contact 51b. When capacitor bank 56 becomes discharged valve 45 conducts, energizing relay 51, thus closing contacts 51c to connect the now charged capacitor bank 64 to the grid of valve 46 so that this valve now becomes cut-off. Relay 14 then releases closing contacts 14c to charge capacitor bank 56 ready for the next cycle. The required manual control is effected by varying the mark/space ratio and the p.r.f. of the output from the circuit by varying the time constant of the circuit comprising capacitor bank 56 and resistors 61, 62 and that comprising capacitor bank 64 and resistors 65, 66. Either the capacitance or the resistance may be varied.

Filed: 1949-12-21
Abstract: 663,703. Luggage carriers for vehicles. DESCHAMPS O. LECANU-. Dec. 21, 1949 [Oct. 3. 1949]. No. 32710/49. Class 103(ii) A removable luggage carrier for motor-cars of the type including points of support which rest on the roof of the car and tension bars with adjustable tensioning means adapted to engage with lateral projections at the sides of the mctor-car body such as door fillisters, is characterized by the fact that the two opposite side members of the luggage carrier each present a straight substantially horizontal intermediate portion terminating in two downwardly sloping portions each carrying a resilient or shock-absorbing supporting base surface, and are each combined with two vertical posts or uprights, each carrying an additional supporting base surface, said uprights being rigidly interconnected by an auxiliary side member on which the corresponding tension bar is secured. The carrier comprises side rails 1 each of which terminate in rubber supporting pads 2. Two posts 4, slidably mounted on each tube 1 by means of collars 3, are rigidly interconnected by a rail 6 and formed with additional rubber supporting pads 5. Cross-rails 8, slidably mounted on the rails 1 by means of collars 9, support angle-section rails 11 which support slats 12 overlaid at their ends by a strip 13, the whole being clamped together by upwardly inserted bolts (not shown), which pass through spacer tubes 10 and are threaded into the rails 8. A transverse tubular rail 14 is rigidly secured at its ends to the rail 3 and is adapted to receive rods 15, to the lower extremity of each of which is pivotally secured a tube 16. A clamping plate 7 is welded to a bar 21 threaded internally to receive a bolt 23, the bar and the bolt being respectively inserted upwardly and downwardly within the tube 21. Each rod 15 is locked within the tube 14 by a bolt 19 and the pivoted connection between the tube 21 and the extremity of the rod 15 is offset towards one end of the tube 21 so that when the tube is rotated 180 degrees, the distance between the carrier and the plate 14 is varied for the purpose of adjustment.

Title: Improvements relating to weighing machines
Inventor: SEDDON HENRY
IPC: G01G19/22
Filed: 1962-08-27
Abstract: 973, 606. Automatic feed weighers. AUTOPACK Ltd. Aug. 13, 1963 [Aug. 27, 1962], No. 32769/62. Heading G1W. Weighing apparatus comprises a plurality of weighing mechanisms 10 (Fig. 1), weigh pans (not shown) of which are arranged with the aid of a timing mechanism to discharge measured quantities of material successively into discharge shoots 15, 16, 17, 18 having a common outlet or adjacent outlets, and wherein the or each outlet has a flap whereby material can be retained in a shoot, and a control means for the flap interconnected with the timing mechanism to permit discharge of material from a shoot and arranged so that further material cannot be discharged from a weigher into a shoot until the previous measured quantity has been discharged from the shoot. The weigh pan discharge means are actuated by solenoids 11, 14 (Fig. 2), the flaps and shoots 15, 16 by solenoid 22 and the flaps on shoots 17, 18 by solenoid 24, the solenoids being energized to open a flap. The timing mechanism includes cams on a shaft (not shown) synchronized with a conveyer (not shown) carrying containers to be filled. The cams sequentially actuate timing switches 41, 42, 43, 44 controlling the shoot discharge solenoid and also actuate control switches 37-40 so that the discharge from a weigh pan cannot take place until its associated shoot is emptied and the shoot closure flap closed, so that each weighing mechanism is used once in a cycle. Discharge from a shoot can only take place when a container is in place to be filled. This is ensured by a switch 32 momentarily operable by a container which energizes a relay 31 through the contacts 31a, 31b of which, the discharge solenoids are energized. Normally closed switches switches 33, 36 are momentarily operated by cams (not shown) in their associated weighers, when the filling of a container is completed and relay 31 is thereby de-energized. Alternatively there may be a flap pivotally mounted at the junction of two shoots (Fig. 3 not shown) which can be selectively moved by a solenoid to close either shoot.

Title: Improvements in or relating to electrical time base circuits
IPC: H03K4/12
Filed: 1936-11-30
Abstract: 486,041. Valve generating circuits ; electron beam valves ; television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., PLAISTOWE, D. L., and FEWINGS, D. J. Nov. 30, 1936, No. 32837. [Classes 39 (i), 40 (iii), and 40 (v)] An electron beam valve is used for discharging the condenser of a relaxation oscillator for generating saw-tooth voltage. Series condensers 13, 14 are slowly charged from a source 11, 19 through a variable resistance 12, and are rapidly discharged by an electron beam passing from the cathode 2 to the outer anode 7 of the beam valve 1. The cathode 2 and an apertured electrode 3 form an electron gun, the beam from which strikes the inner anode 5 whilst the condensers 13, 14 are being charged. When the desired voltage is attained a side electrode 9 connected to the anode 7 through a switch 15, 20 deflects the beam so that it reaches an aperture 6 in the inner anode 5 and passes therethrough to strike the outer anode 7, thus discharging the condensers 13, 14. As the beam leaves the anode 5, a positive pulse is applied from this anode to a second deflecting-plate 8 through a condenser 21, thus maintaining temporarily the deflection of the beam. As the beam returns, the starting of current to the anode 5 gives a negative pulse to the plate 8 and accelerates the return movement of the beam. External synchronizing pulses may be applied to a deflecting-plate 10 lying opposite the plates 8, 9. When the oscillator is not required to be selfoscillatory, the switch 20 may be thrown over to the contact 16 so that the plate 9 is maintained at a fixed voltage by a tapping 17, the action then being dependent on the receipt of a synchronizing signal on the plate 10. When. synchronizing signals are of opposite polarity to picture signals, both may be applied to the plate 10 without preliminary separation. Potentiometer tappings 22, 25 apply normal positive voltages to the plates 8, 10.

Abstract: 1,012,691. Transistor logic circuits. RADIO CORPORATION OF AMERICA. Aug. 21, 1963 [Sept. 11, 1962], No. 33164/63. Heading H3T. A logic circuit comprises a plurality of transistors connected in the common collector configuration and having a common emitter resistor, the emitters being connected via a level shifting device to the base of a further transistor of opposite conductivity type to the first-mentioned transistors, the further transistor being connected in the common emitter configuration. Fig. 1 shows a positive NAND or negative NOR circuit suitable for fabrication on a single chip of germanium or silicon. When any of the input signals at terminals 14a . . . 14n is zero, the appropriate emitter follower is conductive so that the output transistor 30 is non-conductive, giving a positive output at terminal 48. If all the input signals at 14a . . . 14n are positive, all the emitter followers must be non-conductive and hence the output transistor 30 becomes saturated, giving a substantially zero output at 48. The level shifting diodes 36, 38 should have a recovery period of at least 4 Á's and a threshold voltage greater than the saturation voltage of transistor 30 and be formed of the same material (Si or Ge) as the output transistor 30 so as to provide temperature compensation. The charge stored in the level shifting diodes should be greater than that stored in the base/emitter region of transistor 30 so as to provide a strong turn-off overdrive for transistor 30. In Fig. 3, the level shifting diodes are replaced by emitter followers 80, 60. Diodes 72, 94 prevent or reduce the degree of saturation of transistor 30, 60 by limiting the base current drive provided by the preceding transistor. In Fig. 2 (not shown) the emitter follower 80 is replaced by a level shifting diode.
