Title: Automatic timing and control gear for conveyor mechanism
IPC: B65G23/00
Filed: 1948-05-04
Abstract: 636,802. Feeding &c. appliances for animals. PATCHETT, R. J. May 4, 1948, No. 12177. [Class 5 (ii)] [Also in Group XXX] In an automatic timing and control gear for conveyer mechanism, e.g. traversing the food and water hoppers of a poultry battery, an electric reversing switch co-operating with an electric motor is actuated by the tilting of a liquid or other container in one direction or the other caused by a flow or passage of liquid, lead shot or the like alternately from one compartment of the container into another. The container 2 is pivoted at 3 to a framework 1, and comprises compartments 4, 5 and an intervening chamber 6 which is divided into two by a midfeather 7. Orifices 8 and 10 are provided in the walls of chambers 4 and 5 and an orifice 9 in the midfeather 7, controlled by means of a valve member 11. The rear of the container is preferably provided with observation windows 4A, 5A. An endless cable 18 passes around three pulleys 17 and a pulley 16 upon the shaft of a rotary reversing switch 15 having an intermediate stop position. The upper pulley 17 is adjustable within a slot for tensioning. Projections 20A and 20B on the cable are adapted to engage eyelets 12, 12A on the container such that tilting of the container operates switch 15. A pair of curved levers 13, 14, whose upper ends are provided with rollers, are pivoted to the framework 1 and cables, not shown, connect their lower ends to brackets 27, 26, respectively, which are secured to pivoted arms 24, 23, respectively. The cables or the like of the food and water traversing conveyer pass through slots 25 in the arms 23, 24, one placed in the upper run and one in the lower. Torpedo-like projections on the cables are adapted to engage the arms 23, 24 at the ends of traverse of the conveyer so that one or other of the curved levers 13, 14 is actuated, the roller of which engages the side of the container which is down and raises it to the neutral position, just beyond dead centre, so that switch 15 stops the conveyer. Liquid then flows between the chambers under control of valve I until the container overbalances in the reverse direction, reversing switch 15. The apparatus functions continuously in this manner, such that the food and water hoppers are stopped at the end of each traverse for a period predetermined by setting valve 11, so that poultry in the end cages have sufficient time to feed and drink.

Title: Improvements in or relating to methods and apparatus for the continuous heat treatment of materials
IPC: C03B5/14
Filed: 1967-03-15
Abstract: 1,211,224. Glass melting. PILKINGTON BROS. Ltd., E. COEN, J. V. ALDERSON, and R. SMITH. 11 March, 1968 [15 March, 1967], No. 12233/67. Heading C1M. [Also in Division F4] In a method for the continuous production of a stream of molten glass, glass forming materials (e.g. pelletized batch of glass marbles) are continuously and evenly distributed on to a moving hearth, heated to melting temperatures whilst maintained stationary relative to the hearth, and continuously and progressively removed as molten glass from the hearth at the same rate at which the materials are distributed on to the hearth. A furnace 1 is provided with a circular heating chamber 2 defined by refractory muffles 17, 18 which are heated by gas burners 16 on the side opposite the chamber 2. A rotary member 4 supported on a rotary shaft 33 is located centrally of chamber 2 and carries a hearth 20 integral with a centre boss 23. The hearth is covered with a platinum/ rhodium alloy 24 and has a raised flange 25 at its inner edge adjacent boss 23 and a flat outer rim. Material to be melted is fed down a shoot 5 the lower end of which is defined by walls 40, 41, 42. The fourth wall defines a scraper 6. The walls 40-42 serve to prevent the newly melted material from flowing off the hearth in the initial stage and also any foam resulting from raw batch from circulating with the hearth. The molten glass is removed by the scraper and falls as a stream into a shoot 45 and from there to any further processing step. A sand seal 35, 36 is arranged where the hearth drive shaft enters the furnace to prevent ingress of air; and a liquid seal 46 is likewise located at the base of shoot 45. The drive shaft 33 is air cooled. The muffles 17, 18 can be dispersed with an electrically heated furnace. In an alternative embodiment the scraper 54 (Fig. 3) is divorced from the base of the delivery tube 5a and is pivotally mounted on a silicon carbide rod 53 in a silicon carbide tube 52 with its blade adjacent but not touching the surface of the hearth. Consequently any stones or other unmelted batch pivot the blade and recycle until melted.

Abstract: 813,716. Thermal switches. ROBERTSHAW-FULTON CONTROLS CO. April 17, 1957 [April 17, 1956], No. 12488/57. Class 38(5). In a thermal switch (shown diagrammatically in Fig. 1) having an anticipatory heater 24 for opening the switch contacts 20, 22 slightly before the desired temperature is reached, a first circuit from the moving contact 20 via a lead 28 to a movable tap 32 on the heater 24 is in parallel with a second circuit from the moving contact to the movable tap via the temperaturesensitive element 16. As shown, the temperature-sensitive element is a bi-metallic spiral with its fixed end 18 connected to a fixed tap 38 on the heater 24. Contacts 20, 22 actuate a solenoid 12 controlling a room-heating furnace. To ensure that the anticipatory effect of the heater 24 increases continuously as the tap is moved from the end 26 to the end 30 of the heater, the resistances of the heater 24 and the bi-metal 16 are related to the heat transfer contents of these elements in a manner described in detail in the Specification. A ballast resistor 40 may be connected in series with the bi-metal to bring the resistance of the latter up to the required value. The movable tap may also be used to provide the same anticipatory effect for solenoids taking different load currents. Figs. 5 and 6 show a thermal switch in which a spiral bi-metal 16 carries the moving contact 20, co-operating with a fixed contact 22, at its free end and is fixed at its inner end to a shaft 18 mounted in a cantilever bearing on the support plate 50. A follower 88 on an arm 86, secured to the shaft 18, abuts a cam surface 90 formed on the operating-temperature control arm 92 and is kept in contact therewith by a spiral spring 170. The anticipatory heater 24 is mounted below a plate 110 spaced from the support plate 50 by pillars 54, 56. An adjustment member 146 is pivoted on the plate 110, one arm 147 of the member having an index 148 cooperating with indicia on the plate and the other arm 32 passing through a slot 114 in the plate and sliding along the heater to form the movable tap. The ballast resistor 40 is formed from a single loop 153 of resistance wire threaded through a sheet of insulating paper 158 as shown in Fig. 9. One side of the paper 158 is covered with a strip of masking tape and the resistor is positioned on the inside of the inner spiral of the bi-metal as shown in Fig. 6.

Title: Improvements in and relating to the production of acrolein and ethylene
IPC: C07C1/247
Filed: 1943-08-10
Abstract: Acrolein and ethylene are produced by heating 2 : 3-dihydropyran at a temperature exceeding 350 DEG  C. and between, preferably, 450 DEG and 500 DEG  C.  The process may be carried out by simple thermal decomposition in a reaction vessel made, for example, of glass or mild or stainless steel, which may contain filling bodies such as silica chips or pellets of aluminium silicate.  The reaction takes place satisfactorily at atmospheric pressures but reduced or increased pressure may also be used. The dihydropyran may be produced in situ by passing tetrahydrofurfuryl alcohol into a reaction vessel packed with a dehydrating catalyst and heated to above 400 DEG  C. and by suitable choice of reaction temperature and space velocity, the dihydropyran as it is formed, is converted into acrolein and ethylene.  In examples: (1) 2 : 3-dihydropyran is passed through a tube containing silica chips and heated to between 500 DEG  and 550 DEG  C., yielding acrolein and ethylene; (2) dihydropyran is passed through an empty mild steel tube heated to 450 DEG -500 DEG  C. Specification 547,334 is referred to.  The Provisional Specification states that known cracking catalysts may be used in thermally decomposing the dihydropyran.
