Patent GB-440172-A (GB)
Title: Improvements in or relating to the exothermic treatment of solid materials in rotary furnaces
IPC: F27B7/20
Filed: 1934-03-16
Abstract: The rate of an exothermic reaction effected in a rotary furnace between a solid material and a gas, e.g. between sulphide ores and air, is kept substantially constant by passing the charge through the furnace in a layer of such thickness that, in the early stages, the reaction is retarded by the heat absorbed in warming up the mass of material, which is large in relation to its active surface, while there is a corresponding acceleration in the later stages owing to the sensible heat stored in the mass.  The furnace is arranged horizontally or substantially &c., and the required depth of charge is maintained by one or more dam rings.

Title: Improvements in or relating to roll-forming machines for sliver and like material
IPC: D01G15/62
Filed: 1947-03-28
Abstract: 631,134. Sliver-roll-forming machines. LOW & CO., Ltd., J. F., and HUGGINSON, T. March 28, 1947, No. 8426. [Class 120 (i)] A roll-forming machine for sliver and like material comprises two horizontal arbors 8, 8a slidable on vertical columns 12, 12a and movable in a horizontal plane, columns 12, 12a being rotatable to cause said'arbors to move away from or towards each other, rotatable forming rollers 7, 7a, located below the arbors, means to cause the columns to rotate and thereby to cause the arbors to move away from one another when a roll wound thereon attains a predetermined size, means to eject the roll, and means for resetting the mechanism to prepare the machine to repeat the cycle of operations after the ejection of a roll. As shown, arbors 8, 8a, fitted with pins 16 to catch and break the sliver at the beginning of a new roll, are mounted on racked carriers 10a which are in mesh with toothed sleeves 11, 11a slidably keyed to columns 12, 12a to which are attached sectors 14 in mesh with a rack 15. A driving shaft 37 is connected through two sets of clutch members to a pinion driving rack 15, the clutch members being operable to move the rack in one direction or the other to cause arbors 8, 8a to move towards or away from each other. When roll 6 reaches a predetermined size, an adjustable rod 49 contacts a lever 50 to actuate the appropriate clutch members to drive rack 15 in the direction to cause the arbors to withdraw from the roll. The arbors then fall under their own weight to rest on rollers 7, 7a, allowing a knee lever 17, normally engaged by an abutment 18 moving with the arbor assembly, to pivot. An ejection roller 21 is thereby permitted to move under spring action to eject the formed roll 6, and a rod 24 to move so that a pawl 25 contacts a lever 27 to actuate the other clutch members to drive rack 15 in the opposite direction so as to move the arbors towards each other to engage the sliver and start another roll. Rack 15 is provided with pins engageable with levers which act to disconnect the appropriate clutch when the rack has reached the end of its travel in either direction. The clutches may be hand-operated to eject the roll at any stage during its formation, and to re-set the machine. According to the Provisional Specification, the spring-loaded ejecting roller may be engaged by the roll before the latter has attained its full size, so that when the arbors are withdrawn, the pressure of the ejecting roller will eject the roll. Instead of simple axial withdrawal, the arbors may move away from each other in a swinging movement or may be withdrawn in two stages, the first stage being an axial retraction and the second a swinging movement which acts to eject the sliver roll. Such an arrangement is described in detail in the Provisional Specification, the arbor-resetting clutch being operated through a lever which is depressed towards the end of the arbor drop.

Filed: 1974-02-25
Abstract: 1410747 Valves HORTON MFG CO Inc 25 Feb 1974 [29 Nov 1973] 8448/74 Heading F2V In a thermally-actuated snap-acting valve for controlling an air-operated friction clutch a thermal actuator 72 in the water jacket of an engine acts via a sleeve 50 and springs 76, 78 on a valve member 28 which carries a magnetic disc 46 disposed between magnets 92, 96. When water temperature rises the plunger 64 moves the sleeve 50 upwardly against the spring 60 to compress spring 76 until the magnetic force of attraction between disc 46 and magnet 92 is overcome and the valve member starts to move upwardly. At this point the stored energy in spring 76 and the magnetic attraction between disc 46 and magnet 96 is such as to move the valve member rapidly upwardly to cut off the communication of service port 126 with exhaust 118 and open communication between service port 126 and pressure inlet 100.

Title: Improvements in or relating to time switches
IPC: H01H29/28
Filed: 1946-03-19
Abstract: 609,654. Mercury switches. SVENSKA LASMUTTER AKTIEBOLAGET. March 19, 1946, No. 8562. Convention date, April 4, 1945. [Class 38 (v)] A thermally-operated switch in which two contacts are bridged by mercury when a heater is energized and opened automatically after a predetermined time comprises as shown in Fig. 1 a tube which may be of V-shape, having two compartments 1, 2 filled with gas and connected by a constricted passage 3 of which the width is greater than the height. When mounting the switch the tube is laid in a horizontal plane, whereby the mercury leaves a portion of the passage 3 free so that the mercury is distributed uniformly in the two compartments and the gas pressure is equalised. Dipping into the mercury are two contacts 4, 11, the latter being connected to a heating wire 9 having an external connection 10. Heat from the wire 9 may be absorbed in a body 12 having a large heat capacity, whereby the cooling period may be extended. An insulating cup 6 is situated in the compartment 2 and contains mercury 7 in contact with a terminal 5. When the wire 9 is energised the expanding gas in compartment 1 forces the mercury into compartment 2 completing the circuit between the terminals 4, 5 and breaking contact between 4 and 11. By keeping the terminal 10 in contact with a source of current the mercury makes and breaks contact between the terminals 4, 5 at regular intervals. Fig. 3 shows a modification in which a straight tube is divided by a vertical partition 18 leaving a passage 3 at the bottom of greater width than height. The Specification as open to inspection under Sect. 91 describes a modification of the construction shown in Fig. 1 in which the terminal 5 dips into the mercury at the top of cup 6, a bead threaded on the terminal wire resting on the top of the mercury to form an arcpreventing means. A circuit is also described for illuminating a number of lamps on a staircase, the lamps being automatically switchedoff after a predetermined time. Fig. 7 (Cancelled) shows an arrangement for lighting a lamp 19 for a predetermined time after a button 22 has been pressed to close the circuit through the heater 9 and lamp 19. Additional heaters 28, 29 make contact with the mercury and are connected to a potentiometer 32 in series with the supply mains. This subjectmatter does not appear in the Specification as accepted.

Abstract: 352,046. Spray-baths. FRANK, P., 121, Nieuwe Parklaan, Scheveningen, Holland. March 18, 1930, No. 8666. Convention date, Feb. 11. [Class 26.] Apparatus for the treatment of various parts of the human body comprises a movable carrier to support known treating devices including means whereby such devices can be brought into use without manual effort, which can be reciprocated along stationary guiding means between two reversing points or moved into any desired stationary position. Adjustable means are provided actuated by the carrier whereby the direction of motion can be automatically reversed. The apparatus can be used for spraying and atomizing medicaments and cosmetics in liquid form. In the example shown in Figs. 1 and 2, the carrier 3 engages with a screwthreaded spindle 4 by means of members 5 carrying screw-threaded eyes 5a. On rotating this spindle by suitable means, e.g. an electric motor, the carrier 3 can be moved up and down. The members 5 pass through a slot in the wall of the pillar 2, the said slot being rendered fluidtight by an endless band 18 of rustless steel. The carrier may be stopped at any height by suitable control of the driving mechanism, or may be reciprocated continuously, reversal of the direction of rotation of the spindle 4 being effected electrically or otherwise by a trip device 7, comprising for example an electrical contact arranged to strike against the vertically adjustable contacts 8, 14. The contact 14 is adjusted by means of a screw-threaded spindle 13 rotated by a hand-wheel 9 through the bevel gearing shown. A similar spindle 13a is provided to adjust the upper contact 8 (see Fig. 2). The position of the contacts may be rendered visible on an indicator driven from the shaft 16. The carrier 3 may accommodate any desired number of appliances which may be interconnected with its driving mechanism, and they may be so connected with their operating means that on completion of the treatment they may be hermetically closed. Air may be supplied to the carrier through a valve, e.g. a ball valve situated at the point 19. The guiding means for the carrier may also be arranged for horizontal movement, or it may be attached to a wall or ceiling, so that it can be used after the fashion of a movable shower bath. The whole apparatus may be arranged to rotate by suspending it, e.g. by a ball-and-socket joint, at its upper end, and correspondingly guiding the lower end. Thus, if the device moves circularly, it will spray a body in the middle at all levels and from all sides, or a body may be sprayed spirally by this arrangement. The apparatus when arranged to act as a coin-freed machine, is provided with a hinged cork slab 20, which serves to close in the operating means, and is released by the coin mechanism.
