Title: Process for the treatment of domestic refuse
IPC: C05F17/00
Filed: 1961-11-14
Abstract: 921,006. Fertilizers. J. BINNS. Nov. 14, 1961, No. 40730/61. Class 111. Municipal domestic refuse is fermented to form compost after addition of water which has been raised in temperature by heat derived by incinerating a part of the refuse. The optimum fermentation temperature is thereby reached in about 24 hours instead of 3 days, as when cold water is added to the refuse as described in Specification 919,955. The ashes from the incinerator which preferably contains a tins cleansing chamber, may be added to the refuse either before or after fermentation. As shown, municipal domestic refuse is deposited in pit 1, where 30-45% of its weight of hot water, e.g. at 140‹F., is sprayed on the refuse from pipe 2. The wet mass is then conveyed to fermentation cell 3, where the temperature is maintained at 150‹F. for 3 days by injection of air. The partially fermented material is then conveyed via hopper 4 and belt 5, past metal extractors 6 and 7 and screen 8, to a pulverising mill 9, whence the ground material (approx.# inch mesh) is transferred by belt 10 to cell 11, where fermentation is completed at 150‹F with the aid of water sprays and compressed air. The flue gases from incinerator 12 pass through a tins cleansing chamber 13 and then through water-heater 22, before escaping at chimney 19. Hot water is supplied via calorifier 21 and pump 24 to the pipe 2, to be sprayed on to the refuse. Swinging jib 14 loads and unloads tins from 13 and transfers ashes from trough 23 to hopper 4.

Filed: 1975-10-06
Abstract: 1530314 Fluid wall reactors THAGARD TECHNOLOGY CO 6 Oct 1975 40886/75 Headings BIF and B1X [Also in Divisions Cl C7 and F4] Chemical reactions at elevated temperature are carried out by causing radiation to be incident on one or more reactants in a reaction zone defined by a wall of fluid transparent to that radiation, the wall of fluid being located within a heat shield of refractory material which reflects radiation, sufficient radiant energy being absorbed in the reaction zone to raise the temperature of the or at least one reactant to sustain the reaction. If necessary a target material may be introduced to absorb the radiation and transfer energy to the reactants. Additional initial heating means may be provided within the reactor tube. In the embodiment of Figs. 1A and 1B a porous reaction tube 61 having an inlet end 62 and outlet end 63 is contained within a cooled pressure vessel 70 forming a plenum 85 into which fluid is admitted at 83 and passes through the porous walls of the reaction tube to form a protective blanket for the inner wall thereof. Electric heating elements 101 a-c heat the reactor tube so that it emits radiation. A heat shield 120 is provided within the plenum. Reactants are introduced in a gaseous stream at 91 through a diffuser 95. Solid reactants or target material are introduced at 121. Cooling means may be provided at the exit end. A broadly similar but more elaborate structure (Figs. 6A to 14, not shown) comprises one or more fog-forming nozzles for introducing the reactants; the reactor tube is coupled to the pressure vessel at the top via bellows and is held in tension by a weight and pulley system; means are provided for coating the surfaces of the reactor tube, heating elements and heat shield with a refractory oxide prior to use as an anticorrosive coating and for decreasing or increasing the pore size of the reactor walls during reaction by deposition of carbonaceous material or etching respectively, said means comprising means for feeding suitable reactants to the reactor. Automatic control means are also described. A variable temperature profile heat exchanger (Fig. 12, not shown) for cooling exit gases comprises a pair of refractory walls having a spiral refractory baffle between to define a spiral, annular coolant channel, the coolant after passing through the channel may be discharged into the plenum of the reactor proper.

Title: Sorting apparatus
IPC: B07C5/342
Filed: 1965-09-28
Abstract: 1,130,152. Photo-electric colour sorting of objects. ELCEMCO Inc. Sept.28, 1965 [Sept.28, 1964], No. 41257/65. Heading G1A. In an arrangement for sorting a succession of moving objects e.g. coffee beans 16, Fig. 1 passing down a transparent tube 12 according to the intensity of light reflected by them as they pass through a point in their path on which light is focussed from a ring of sources 58 on a plane transverse to the direction of motion, the reflected light is detected by one or two annular sensors 46 situated above and/or below the focussing point and centred on the axis of the tube to produce a signal for controlling a sorting deflector 26 in accordance with the combined detector outputs or of the ratio of the outputs. The acceptable range may be a middle range with signals outside the range permitting operation of the deflector and the selection parameters may be adjustable. The lamps may have lenses in their envelopes. Light filters for example red and green may be positioned over the respective sensitive surfaces of the cells in an arrangement where the ratio of the signals effects control. A photo-electric object presence detector 20, 22 is positioned at the bottom of the tube, and produces a pulse for operating the deflector in response to each object and the pulses are suppressed or permitted to pass by a gate circuit (86) Fig. 4 to which pulses derived from the annular detectors are also applied. The amplifier signals from detectors (46) are applied to voltage level detector circuits (74), (76) responsive to respective first and second pulse levels. These circuits which are monostable transistor circuits and are switched when input plus adjustable bias exceeds a predetermined value, apply pulses to a disabling circuit (78) which also includes a monostable multivibrator (118), (120). An input pulse from circuit (74) switches the pair and a unijunction transistor (126) is fired by the build up across a capacitor (130). A disabling signal established across a resistor (142) is applied to the gate circuit and the voltage across a resistor (140) switches the pair (118), (120) back to normal. A pulse from circuit (76), indicating a higher level signal from the photo-cells, switches the pair (118), (120) back to normal before a disabling signal can be established. A deflector operating coil (170) is connected in the emitter circuit of a power transistor (168) and may control a rocking deflector, a bent spring, or an air jet, to deflect wanted or unwanted objects, as desired, accoding to which predominate. A circular aluminium conveyer wheel for supplying objects individually in succession to the mouth of the tube has cut away tubular scoops mounted around its periphery, and is rotated through the beans to lift them to the tube mouth where they are injected by compressed air. The scoops may be constructed by force fitting short lengths of tubing into holes in the wheel and the blast of air injecting the object may be used to remove dust or beans of small size. Objects may be thrown into the tube from the wheel by centrifugal force.

Title: Apparatus for handling glassware for inspection or the like
IPC: B07C5/12
Filed: 1967-09-18
Abstract: 1,133,289. Conveyers. EMHART CORP. 18 Sept., 1967 [26 Sept., 1966], No. 42323/67. Heading B8A. Glassware articles C are diverted by a member 180 from an endless conveyer 12 for transmission by an endless belt 26 and co-operating spring loaded guides 30, 32, 36, to an inspection station at a point along the conveyer 26. The articles then pass on to a rotating platform 134, and if they are not to be rejected, they are carried round to engage a member 136 which deflects them back on to the conveyer 12. Otherwise, a member 148 is deflected from a dotted line position (Fig. 1) to a second position (full lines) in which the article is directed by the member 148 to a radially-inward position. It then misses the member 136 and passes round on the platform 134 until it is directed by a member 156 into a central discharge shoot 160. The platform 134 is supported by wheels 168, each of which is adjustably tiltably mounted so as to suitably match the height of the platform 134 to the level of the conveyer 12. The platform is positioned and driven by peripherally disposed wheels 164, 164b, and a driving wheel 164a. Each article approaching the inspection point operates a member 104 of a switch 106 thereby energizing a solenoid 112 for a timed period. This causes actuation of a link 54 and gears 114, 116. The gear 114 causes clockwise movement of a member 50 carrying a portion 34 of the article guide member 32, and the gear 116 results in anticlockwise movement of an arm 120 carrying two article-engaging rollers 122. The latter press the article C against a rotating friction-surfaced roller 28. Light from a source 130, and reflected by the rotating article, is picked up by a number of devices which may comprise fibre-optic bundles associated with respective photo-cells. If any of these detect a flaw, a signal is transmitted to a solenoid (150) (Fig. 4, not shown), which causes rotation of the member 148 to its full line position (Fig. 1). The mechanism is vertically adjustable on frame members 68, 70, 72, in order to adapt the apparatus to articles C of different sizes.

Abstract: 1307126 Nerve stimulators for dental applications B JANKELSON 4 Sept 1970 [5 Sept 1969] 42521/70 Heading A5R A stimulator for dental applications comprises a pulse generator 16 connected to input electrodes 10 and a common return electrode 14, and a support for fitting on the head so that the electrodes 10 are located in contact with the skin over the roots of the mandibular and facial nerves and the electrode 14 contacts the back of the head so that the masticatory and facial muscles are contracted in co-ordination. The nerves may be stimulated with pulses at about 40 pulses per minute using 10 to 35 volts, the output current being controlled by a control 24. The electrodes 10 are both normally connected to one pole of the generator but a switch 22 allows individual connection so that the resistance of the two circuits from electrodes 10 to electrode 14 can be checked to ensure equality of current flow through the electrodes 10. This check is effected using a switch 29 which applies 1.5 volts d.c. between the electrode 14 and chosen electrode 10, the current flow being indicated by a meter 28. The apparatus may be used to aid in the diagnosis of the comparative degree of relaxation or contractive of the muscles on each side of the face, to cause the mandible to close to allow determination of the horizontal myocentric and vertical positions of occlusion, and to take dental impressions. To register the initial contact points of worn teeth to allow occlusal adjustment of worn natural dentition or of existing bridgework at an overdosed vertical height, wax or carbon paper is placed between the teeth and the fifth and seventh cranial nerves are stimulated by the apparatus using an "overclosure" control 26 which allows stimulation at variable currents at about 110 pulses per minute.
