Patent GB-496190-A (GB)
Title: Electrically operated volumetric weighing apparatus for granular materials
IPC: G01G13/02
Filed: 1938-05-26
Abstract: 496,190. Automatic - feed weighers. SOC. DES COMPTEURS VOLUMETRIQUES. May 26, 1938, No. 15707. Convention date, Nov. 4, 1937. [Class 143] An apparatus for determining automatically the volume and weight of granular material comprises a weigh hopper carried by a lever system connected to an automatic steelyard, a supply hopper from which the weigh hopper is always filled to a constant extent, a shutter separating the supply and weigh hopper, a discharge door at the base of the weigh hopper and electrical means set in action through the initial impulse of an electric motor for releasing the automatic steelyard and for operating the shutter and discharge door The material is delivered to a supply hopper 12 having a volume greater than that of the weigh hopper 3. The material accumulating in the supply hopper ultimately presses upon and closes an electric contact 13 thereby starting a motor 15 which rotates a contact-bearing distributer 18 and opens and closes a shutter 14, sufficient time being allowed for the weigh hopper 3 to fill, the flow being arrested by choking at the mouth of the weigh hopper. A constant volume is thus ensured in the hopper and the number of volumes discharged may be registered on a counter. When the shutter 14 has completely closed, the distributer 18 energizes an electromagnet 5 and also stops the motor 15. The electromagnet 5 releases an automatic steelyard of known kind, and the weight in the weigh hopper 3 is indicated and added to a totalizer. A motor 29 then starts up and returns the steelyard poise to its starting point, the consequent upsetting of the equilibrium causing closure of a contact 6 to start a motor 8. The motor 8 drives a second contact-bearing distributer 11 and opens and closes a discharge gate 7. As the discharge gate closes after liberation of the material, the distributer 11 energizes the motor 15 to reset the same in readiness for the next closure of the contact 13. If, at the end of a series of operations, the material has not risen to the contact 13, a partial load may be weighed by manual operation of a contact associated with a time-delayed relay device which retards the starting of the weighing cycle by much longer than the normal time of filling. The material from the weigh hopper 3 is discharged into a lower hopper. If choking occurs in the lower hopper, an electric contact therein is closed by the pressure and causes the discharge gate 7 to remain open and arrest further operation until the choking has sufficiently diminished. Specification 409,629, [Group XXIX], is referred to.

Title: Improvements in and relating to variable-gain electric signal amplifiers
Inventor: MORGAN ARTHUR GEORGE HENRY
IPC: H03G1/00
Filed: 1959-05-11
Abstract: 888,995. Electric signal transmission systems. ENGLISH ELECTRIC CO. Ltd. May 4, 1960 [May 11, 1959], No. 16040/59. Class 40 (4). [Also in Group XL (c)] The gain of a transistor amplifier is in part varied by varying the gain given by a transistor and in part by variation of a variable attenuator. The signal input is applied to a transistor amplifier 10 in grounded emitter connection which is coupled by resistor 12 to a buffer stage 13, followed by stages 14. In addition to a signal output 15, the stages 14 provides a rectified D.C. automatic gain control voltage on line 16 which is used to vary the impedance of a transistor 23. The transistor 23 forms with silicon diodes 26 and resistor 25 a variable potentiometer which controls the bias voltage applied to silicon diodes 20, 20a and also that applied to silicon diodes 21, 21a. The diodes 20, 20a are coupled by condenser 19 to form a variable A.C. load across a resistor 18 in the emitter circuit of the transistor 10, thus varying the amount of negative feedback on this stage. The diodes 21, 21a form a variable shunt arm in a T-network attenuator, the series arms of which comprise respectively the output impedance of the transistor 10 and the resistor 12. The amplifier may be for use at high frequencies, the stages 14 being coupled by tuned circuits while the stage 10 is aperiodic.

Filed: 1958-05-21
Abstract: 850,420. Treating gases with liquids. BELGE DE L'AZOTE ET DES PRODUITS CHIMIQUES DU MARLY. May 21, 1958 [June 7, 1957], No. 16325/58. Drawing to Specification. Class 55 (2). Water is injected under pressure into a pyrolysis chamber containing hot gases, originating from the pyrolysis of hydrocarbons, in the form or thin substantially fan-shaped sheets through slits which are inclined at an angle of between 2 and 5 degrees to the horizontal so as to be parallel to one another and which are inclined at an angle of between 10 and 15 degrees to the direction of flow of the gases, whereby the sheets initially overlap but subsequently merge to form a stable homogeneous layer of water the area covered by the overlapping sheets being at least equal to the cross sectional area of the pyrolysis chamber. Apparatus used to inject water into hot pyrolysis gases may comprise a pyrolysis chamber of a vertical pyrolysis furnace having at its lower end a portion of increased cross section around which are distributed a plurality of sprayers each of which has a slit inclined at an angle of 2 to 5 degrees to the horizontal, there being means for ejecting water under pressure through the slits, the arrangement being such that when the apparatus is in operation, water is injected into the gases emanating from the pyiolysis chamber in the form of thin substantially fan-shaped sheets which overlap to cover an area which is at least equal to the cross sectional area of the pyrolysis chamber, the slits being inclined at an angle of between 10 and 15 degrees to the flow of the gases. Preferably a curtain of water is formed around the inner walls of the pyrolysis chamber, the water of the curtain flowing downwardly and stretching over the water layer, whereby the formation of a mist of droplets due to the merging of the sheets of water is prevented. Preferably also each sheet of water has an apex angle of 60 degrees. The pyrolysis chamber may be vertical in cross section, the sheets originating from sprayers distributed around a frusto-conical ring at the bottom of the chamber, the sprayers lying on a circle the diameter of which is greater than that of the chamber and is such that the sheets overlap at points disposed around a circle the diameter of which is at least equal to that of the pyrolysis chamber, whereby the area covered by the overlapping sheets is at least equal to the cross sectional area of the pyrolysis chamber. By the above process, during the partial combustion of methane a pyrolysis gas having an 8.4% by weight acetylene contact was obtained.

Title: An improved electro-thermal regulating device, particularly suitable for electrically heated plates
IPC: G05D23/24
Filed: 1954-06-03
Abstract: 778,397. Automatic temperature control systems. NEGROMANTI, A. May 31, 1955 [June 3, 1954], No. 16431/54. Class 38 (4). In a temperature control system for an electric iron, a heating element of zero temperature coefficient and a low resistance temperature-sensitive resistor are connected in adjacent arms of a bridge network whose output operates a relay switch in the bridge supply. The bridge network comprises, in addition to the heater 1 and temperature-sensitive resistor 2, a variable resistor 3 and a constant high impedance 4 such as an incandescent lamp. The bridge is supplied from a D.C. source 5 over a bimetal relay switch 8 whose heating winding 9 is energized from the bridge output. At normal ambient temperatures the bridge is balanced, but as the plate of the iron, with which the detector 2 is in contact, reaches a desired temperature the bridge output becomes sufficient to open the switch 9 and thus deenergize the heater 1 and the relay heater 9. Thereafter, the relay cycles with an " on-off " ratio having a final steady value sufficient to maintain the desired temperature at a value set by variation of resistor 3 or of a resistor (not shown) in series with heater winding 9. The relay contacts and bimetal are initially adjusted to set limits on the range of controlled temperatures. An electromagnetic delay relay may replace the thermal type described, in which case the " off " time may be initially variable by adjustment of a spring.
