Title: Improvements in and relating to drying shafts for granular loose material
IPC: F26B17/12
Filed: 1939-06-10
Abstract: 529,901. Drying and treating cereals and granular material. GRONERT, A. June 10, 1939, No. 17090. [Class 34 (ii)] [Also in Group I] Granular material such as cereals or earth nuts are dried while falling in a vertical shaft so as to surround on all sides, i.e. above and below as well as laterally an internal casing with perforated walls containing a single fan m with suction and pressure. branches forcing hot gas through the grain and drawing in cold air at the grain outlet. The fan motor E may be in the casing below the fan on the suction side and be cooled by air drawn in at u. Cool air is drawn in at the bottom i but air drawn in near the centre passes over steam or other heaters h through the grain to the fan and hence passes out through heat-conducting tubes k, l or when these are closed through the grain at p. The tubes k, l may be open at their undersides for recirculation of air. Girders Z or staggered inverted V-shaped projections stir the grain. Combustion gases may enter a square shaft through inter-communicating triangular ducts at each corner. The internal casing may have a central baffle so that.hot air is drawn through the lower part and forced out through the upper part of the shaft. The wall of the casing carry ing alternate projections may be moved vertically to adjust the space between the projections for different materials. Material is discharged beneath a rotary, cone 8 below which rotary sweeps 9 convey it inwardly and downwardly to the outlet 10. The pressure or partial vacuum in the upper part of the drier may act through a diaphragm valve to control the outlet or the supply of heat to the air heaters. The shaft may be divided horizontally into two and the grain allowed to fall in a narrow ring from one part to the other, and air is blown across this ring to remove impurities, which are drawn by a second fan to a settling chamber. Discharge of grain may be regulated by raising or lowering a cylinder placed over the rotary sweeps, or by rotation of an apertured cylinder, the position of which is shown by a gauge. The sweeps may be mounted in a frame hinged to the end of the shaft. Specification 303.572, [Class 34 (ii)], is referred to.

Title: Means for controlling an engine-driven gas compressor
Inventor: BOYCE GUY BARON
IPC: F02D1/00
Filed: 1957-06-04
Abstract: 826,522. Rotary compressors. HYDROVANE COMPRESSOR CO. Ltd. May 22, 1958 [June 4, 1957], No. 17675/57. Class 110 (2). An internal-combustion engine 2, driving a compressor 3 of the sliding-vane type, has its speed controlled by the pressure at the inlet 6 of the compressor. Compressed air, or other gas, is stored in a tank 5, where oil is separated out and led to a tank 4, the pressure also acting on oil in the tank 4, the oil being supplied to the compressor for sealing and lubricating purposes. The air pressure inside the valve 7 is lower than atmospheric when pressure in the tank 4 rises and forces the valve 7 towards its closing position. This low pressure acts through a pipe 8, valve 14, chamber 11 on the inside of a bellows 12, causing a trunk 15 to move to the right, Fig. 2, act on a piston 16 and actuate a lever 19 and engine throttle control-rod 20. The piston 16 is provided with a flat 21 which provides a restricted passage between the interior of the bellows and the interior of a cylinder 17 which gives a restricted flow from the chamber 11 through an adjustable valve 22. Preferably the bellows and the greater part of the chamber 11 are filled with oil. An eccentric 29, on a spindle 30, may be used, through a handle 31, to effect axial adjustment of a rod 26, the trunk 15 and move the lever 19. With rise in pressure in the pipe 8, the bellows moves in the opposite direction under the influence of a spring on the rod 20. A stack of spring washers 24 slows down the movement of the trunk 15. Fig. 3 shows a modification, the two chambers 10, 11 being separated by a leather, rubber or other flexible material, bellows 12. The trunk 15, serves in place of the piston 16, Fig. 2, being extended into the cylinder 17. The former spindle 30 is dispensed with and replaced by a cam 33 acting directly on the lever 19. Specification 709,813, [Group XXIX], is referred to.

Title: Recording device for use in connection with taximeters
IPC: G07B13/00
Filed: 1923-07-10
Abstract: 223,283. Gluck, J. July 10, 1923. Taximeter; flag mechanism; time-distance recorders.-A taximeter M, Fig. 2, is fitted at the top with a casing H containing a clock-driven record strip T marked by one or both of two pencils 1. 2 reciprocated simultaneously across the strip by a vehicle-driven cam 14, Fig. 4, one pencil 1 being in contact with the strip and the other out of contact when the flag is in the raised or disengaged position, whilst the setting of the flag to a first or second tariff position lifts the pencil 1 from the strip and allows the other pencil 2 to engage the strip. When the flag is set to the " not registering " position during breakdown or other compulsory stoppages, both pencils are released to engage the strip. The pencils are lifted away from the strip when the casing is opened. The initial movement of the flag may causes a punch to perforate the strip to mark the beginning of a hiring period, and another punch may be employed to record the opening of the casing of the recorder. The cam 14 is driven from the usual flexible shaft 20 through a shaft 17, pinions 16<a>, 16<b> and worm gearing 16, 15, Fig. 2, and is engaged by a pin 12 on a pivoted arm 8 connected to a sleeve 6 forming part of a yoke 4 carrying the pencils, the yoke being slidably mounted on a post 3. The flag spindle F, Fig. 2, is geared to a shaft 25 provided with long cams 27, 28, Figs. 4 and 7, which are engageable with the ends 1<a>, 2<a> of the pencil arms. Coiled springs 9, Fig. 4, urge the pencils towards the record strip. The shaft 25 is provided also at the top with a cam 30, Figs. 2 and 3, adapted, when the flag spindle is first moved, to engage a lever 31 carrying a punch 34. The casing H is hinged at the back and is provided with a lug 38, Fig. 3, which moves a slidable punch rod 35 to mark the strip each time the casing is opened. The records are preferably made on a plain strip T, Fig. 8, the perforations x being made by the flag spindle punch, the perforation y by the casing punch, the upper line record l<1> by the pencil 1 when the vehicle is disengaged, and the lower line record l<2> by the pencil 2 when the vehicle is engaged. The records may be examined after detachment from the instrument, the punch mark y giving the known time the vehicle left the garage. The casing is provided with a link 48, Fig. 3, adapted when the casing is opened to turn a crank 47 and, through a rod 46 on the crank shaft, to move both pencils away from the record strip. The strip is drawn from a roll R, Fig. 3, through guides R<1>, R<2> by a feed roller 41 driven by clockwork C. The feed roller shaft is driven through ratchet gear, Fig. 5, and carries spiked discs 43 co-operating with a grooved roller 45.

Title: Improvements relating to precision balances
Inventor: WHITCROFT ROBERT JOHN
IPC: G01G1/00
Filed: 1960-05-23
Abstract: 982,977. Weighing apparatus. STANTON INSTRUMENTS Ltd. May 23, 1961 [May 23, 1960], No. 18070/60. Heading G1W. A precision balance comprises a weighbeam 28, the movement of which is undamped and which is arranged by its deflection to indicate a change of weight, a beam 8 the movement of which is damped, and means for coupling the two beams so that they move in unison. As shown, the coupling means comprise permanent magnets 44, 45 carried by the beams 28 and 8 and arranged with like poles facing, the beams being out of poise in opposite directions to counteract the force of magnetic repulsion. The weighbeam 28 is enclosed in a chamber 20 from which an extension 22 leads to vacuum or pressure equipment and an extension 24 leads to a heat resistant member 25, thimbleshaped to enclose the weighing platforms 34. A furnace may be lowered to enclose the member 25 and the beam 28 can thus weigh a specimen under chosen conditions of temperature, atmosphere and pressure. Since air damping is preferable to make the movement of the beam substantially dead-beat such damping is applied to the beam 8 by an air dashpost having a moving element 10 hung from the end of the beam and a fixed element 11 mounted on a pillar 9 which carries the supporting knife edge for the beam 8. An extension from the pillar 9 also supports one end of an arm 16 which carries a member 15 which constitutes one electrode of a capacity type follower mechanism, the beam 8 having the other electrode in the described embodiment although the weighbeam 28 could constitute the other electrode. The other end of the arm 16 is connected to a rod 17 which is part of a follower mechanism whereby, if the beam 8 is deflected and the capacity between it and the member 15 changes, the rod is moved to restore the beam, the recording apparatus and weightloading mechanism being controlled at the same time. The weight-loading mechanism operates curve 40 by which weights 38 are removed or added by arms 39. The loading can be supplemented by weights in a canister 37. The beam 8 is associated with arrestment mechanism 13,14 and the beam 28 with arrestment mechanism 31, 34. The canister 37 is reached through a door 23. Suitable sealing means are provided where members pass through the wall of the chamber 20. In a modification there may be a pair of magnets at each end of the beams and in another modification, the beams may be arranged to swing in planes that are at an angle to one another. Specification 756,030 is referred to.

Title: A hydraulic centrifugal regulator
IPC: F02D1/00
Filed: 1951-07-31
Abstract: 696,791. Fluid-pressure servomotor-control systems. MOTORPAL, NARODNI PODNIK, and STRITZKO, V. July 31, 1951 [Aug. 2, 1950], No. 18139/51. Class 135 A hydraulic regulator for the fuel injection pumps of an internal combustion engine comprises a centrifugal pump 1 driven from the engine shaft and housed in a casing which also includes a spring- loaded piston 8 connected to the control rod 37<SP>1</SP> of the injection pumps, and the piston 8 separates the suction and pressure spaces A, B, respectively, of the pump 1. The movements of piston are transmitted to the control rod 37<SP>1</SP> through a lever 12 which is pivoted at its ends on the control rod and the stem of the piston, respectively. The fulcrum 13 of the lever 12 is carried by a bell crank 16, 17 which can be adjusted from the accelerator pedal to set the speed of the engine, the movement of the bell crank being limited by stops 41, 42. The piston is shown in the position it takes up when the engine stops and, in this position, liquid can be fed into the pump casing through a radial passage in the end cap 7 of the casing, and radial passages and a longitudinal passage 46 in the piston stem. In this position also, the piston contacts a plunger to open a valve 38 to allow gas in the system to escape. During the initial movement of the piston to the left, i.e. during the idling range, it is loaded solely by a light spring 20. As the speed increases and the piston moves further to the left, an abutment 26 on the piston stem contacts and moves an abutment 25 which brings a stronger spring 18 in play, although this second spring may be so chosen that no movement of the piston takes place over an intermediate range of speeds i.e. until the fluid pressure on the piston increases sufficiently to overcome the spring 18. The pressure and suction sides of the piston may be interconnected by an adjustable throttle.
