Title: Improvements in and relating to transporting goods from a chocolate coating or like machine
IPC: A23G3/20
Filed: 1941-10-13
Abstract: 553,309. Endless conveyers. POINTON, J. E., TUNLEY, A. A., and BAKER PERKINS, Ltd. Oct. 13, 1941, No. 13163. [Class 78 (i)] Chocolates, biscuits or other goods from a chocolate coating machine or oven are transported by endless band conveying plant of the type in which the goods are automatically delivered to a flexible sheet or plaque as it is brought up over a knife edge or nose at the feed end and conveyed on trays through a cooler, the goods being delivered on to a receiving conveyer as the plaque is drawn downwardly over a discharging knife edge. The feeding, intermediate and discharge sections are shown respectively in side elevation in Figs. 1, 1a and 1b, the trays 12 being mounted on and between two conveyers driven at the same speed. The plaques are removed from and returned to the trays before and after the feeding and delivery points, each of the trays 12 having pivotal connections at about their centres to the conveyer chains 9 one on each side and having also at each end guide rollers 16 which engage guide rails 15 to maintain the trays level. The trays 12, each with a plaque resting upon it, approach the feeding end Fig. 1, along the lower rim 9c of the conveyer chain 9. Each plaque has at its forward end a cross rod 19 which is then resting in a vertical slot 22 at the forward end of the tray. The trays are then reversed at transfer station T along the return run 9d of the conveyer chain and the plaques are removed therefrom by lugs 20 on the plaque endless driving chains 14 engaging the plaque driving rods 19. The plaques are reversed, that is turned upside down, as the lugs 20 with rods 19 follow along the run 27 of the chains 14, and are cleaned by brushes 17. As rod 19 approaches, nose piece 3 is withdrawn momentarily to allow it to pass upwardly and as it travels forwardly over table 1, the plaque is drawn over nose 3 and goods are deposited on it by conveyer 2. Tray 1 slopes downwards at its rear end 11 where rod 19 engages slot 22 in a tray 12 on which the plaque is then laid. The tray and plaque are led upwards to a cooler and downwards over section C of main conveyer chain 9. The plaque is then removed from the tray and is led downwards over delivery nose 33, the goods being deposited on delivery conveyer 18. This is effected by rods 19 moving through grooves 32 while the tray is moved backwardly along run 9a of conveyer 9. Receiving conveyer 18 is momentarily lifted to allow passage of rod 19. Rods 19 are picked up by slot 22 in a tray 12 travelling along run 9b, the plaque being again laid on the tray and travelling back along conveyer run 9c to the transfer point T adjacent the feeding end. The plaques are automatically centred during their forward travel. A modified transfer arrangement at the delivery end is described.

Title: A process for the polymerisation of a conjugated diene
IPC: C08F20/62
Filed: 1962-04-05
Abstract: Polymers of conjugated dienes, e.g. isoprene, are made by effecting the polymerization of the diene with a lithium-based catalyst in the presence of an inert hydrocarbon solvent, at a temperature ranging from room temperature to 80 DEG C., and when the monomer conversion is between 20 and 80% complete adding a chain terminator having an active hydrogen atom in an amount sufficient to destroy the activity of the catalyst, and thereafter adding an additional amount of catalyst which is at least equivalent to the added amount of the terminator.  The lithium-based catalyst may be lithium metal, or a lithium-magnesium alloy, an organo lithium hydride or amide, or a lithium hydrocarbyl such as n-butyl, sec-butyl, or amyl lithium.  The chain terminator may be water, an organic or a mineral acid, an organic amine, or an alcohol, aldehyde, or ketone. Exemplified terminators are methanol, tertbutyl catechol, isopropanol, acetone, methyl ethyl ketone, propionic acid, butyric acid, benzoic acid, maleic acid, propionaldehyde, crotonaldehyde, cinnamic aldehyde, and stearyl alcohol.

Title: Carriage primarily for use in a timber extraction system
IPC: B66C11/24
Filed: 1972-03-22
Abstract: 1440751 Single-cable hoisting and transporting J FLEMING 20 June 1973 [22 March 1972] 13283/72 Heading B8B [Also in Division B7] A carnage 10, particularly for use in a timber extraction system, is shown slung from a burden cable 11 which has an adjustable skid 11a. A haul rope 12 is used to move the carriage 10 to a loading station, and it is moved to an unloading station at the skid position by a haul and hoist rope 13. The rope 13 at its free end has a load hook (not shown), adjacent which is an abutment member 27a. As shown in Fig. 2 a sleeve 17 slidable in vertical guides (not shown) on the carriage 10 and mounting a pulley 26a is biased into its upper position by a spring 18 acting through bell-crank lever 19 and link 20. At the loading station, when a load is applied to the rope 13 the sleeve 17 is moved downwards, against the action of the spring 18, until a bar 42 on the sleeve 17 engages a stop 43 on the carriage 10. The load can now be raised, the abutment member 27a passing through guide rollers 44 into the sleeve 17 where it lifts the free end of a lever 39 pivoted to lugs 40 against a spring 41. This action lifts a bolt 36 clear of a recess 37 in a latch bar 28 which is moved through a bell-crank lever 31 and a link 30a under the action of a spring 25a through a slot 29 into a position below the member 27a, locking the member 27a to the sleeve 17 and thus to the carriage 10. At the same time telescopic rods 22, pivoted to each other at 23 and at their other ends to the carriage 10, are forced into their upper position, Fig. 3 (not shown). The carriage 10 with its load can now be moved by the rope 13 until the skid 11a is engaged by skids 24 on the rods 22 forcing them down and thus withdrawing latch bar 28. This releases the member 27a so that the load can be lowered, the bolt 36 entering the recess 37 to retain the latch bar 28 retracted. Should an empty hook be raised the sleeve 17 is not depressed by the tension in the rope 13 and bar 42 remains in line with the latch bar 28 preventing it from locking the member 27a to the sleeve 17 and thus to the carrage 10. In a further embodiment, Fig. 4 (not shown), the telescopic rods 22 are replaced by strikers (65) at either end of the carriage 10, the skid 11a being replaced by adjustable stops. In this case the latch bar 28 is withdrawn to release an abutment member (59a) from the sleeve 17 when a striker contacts a stop.

Title: Improvements in or relating to ore reducing machines
IPC: B02C17/10
Filed: 1935-05-03
Abstract: 441,972. Impact pulverizers. HARDINGE CO., Inc., 122, East 42nd Street, New York, U.S.A.-(Assignees of Hardinge, H.) May 3, 1935, No. 13284. Convention date, May 16, 1934. [Class 59] In an ore-reducing machine in which a revolvable drum carrying buckets drops ore onto a stationary impact medium in the bottom of the drum, a screen or grizzly is provided within the drum to intercept the material first discharged from the buckets and to separate the fines from the coarser particles, the fines being diverted out of the drum to a classifier which rejects the coarser particles back to the drum. As shown a drum 11 comprising a peripheral plate 12 and annular end plates 13, 14 is provided with elevating buckets formed by plates 16 and inwardly directed plates 22 at the outlet to restrict the opening. The drum is mounted on wheels 37 carried by limbs 27, which are anchored by bolts 41 to beams 39 through rubber pads 44. The centre link 28 is slotted to engage an upstanding guide 43. The drum is driven by an endless chain 46 engaging a toothed wheel formed on the drum. Four inclined impact plates 61 receive the ore dropped from the buckets. The ore is fed to the drum by a hopper and is discharged by classifying the excess ore falling from the buckets onto a grizzly 65. The grizzly is pivoted at 70 to move upwardly if struck by a projecting piece of ore carried by a bucket. The grizzly is perforated so that fines pass into a pipe 72 and are led into an inclined classifier 75 which may be of the kind described in Specification 389,338, whilst the coarse material falls off the grizzly into the bottom buckets. The classifier 75 is rotated by a motor 88 and is provided with helical ribs 81, the coarse material being discharged at the elevated end into a discharge conduit 78 for return to the buckets whilst the fines are discharged with the water into a launder 80.

Title: Improvements in or relating to laundry finishing compositions, and methods of laundering fabrics
Filed: 1945-05-28
Abstract: Fabrics are rinsed after laundering with a bath containing a composition comprising a major proportion of magnesium sulphate or chloride and a minor proportion of boric acid.  Soap residues are thereby converted into insoluble magnesium soaps and are dispersed to such a degree that a substantial portion of the magnesium soap so formed is capable of being flushed from the fabrics when the rinse bath is withdrawn.  When chlorine bleaching agents are used during the laundering, small quantities of sodium sulphite may be added to the rinsing composition.  A typical composition consists of 50-75 per cent of magnesium sulphate, 22.5-47.5 per cent of boric acid and 2.5 per cent of sodium sulphite.

Title: An electromagnetic device
IPC: H02K33/02
Filed: 1959-04-20
Abstract: 905,576. Transducers. KNOWLES, H. S. April 20, 1959 [April 22, 1958], No. 13401/59. Class 40 (4). In an electromagnetic transducer including two permanent magnets 33A, 33B, Fig. 3, secured on opposite sides of a coil 20, a balanced armature 27 works in a space between two polepieces 22, 23, Fig. 2, and is clamped at one end in a clamping gap formed by non-magnetic spacers 28W while its other end is capable of vibration in a working gap 29, a flux-conductive and bendable tab being provided to adjust the reluctance between the polepieces in the gap adjacent the clamped part of the armature. The tab may be a longitudinal extension 40 of the armature 27. Alternatively it may be a thin magnetic shim 51, Figs. 6, 6A, clamped with the armature 50 between non-magnetic spacers. In a modification the armature is T-shaped, having bendable arms integral with the leg portion, Figs. 7, 7A, not shown. The armature 60, Fig. 8, is flanked by transverse magnetic shims 61, 62 spaced from the polepieces by non- magnetic spacers 28W. Alternatively a flux conductive member 70, Fig. 9, is spot welded to pole piece 23 and adjustable relative to polepiece22. The magnets 33AX, 33BX, Fig. 5, may joint the upper polepiece 22 by a non- magnetic gap 65 to increase the reluctance into which the permanent magnets work, thereby producing little change in the total flux provided by the magnets when the reluctance is changed at the clamping gap. Permanent adjustments to the armature may also be made by knifing or bending or by producing certain strains in the armature. The device of Fig. 2 is a hearing-aid receiver, the armature 27 being connected by a link 32 to a diaphragm 31, a tube 19 being provided for insertion in the ear. In a microphone, Fig. 11, not shown, the cover plate 15 is partially covered by grill fabric.

Filed: 1916-09-25
Abstract: 109,834. Matthews, R. L. Sept. 25, 1916. Combined piston and bucket pumps, particularly applicable to deep wells. Fig. 1 shows a vertical section of a pump which is submerged so that, when the piston D moves downwards, water enters the cylinder A through a port H. When the piston rises, the water above it flows past the lift valve B into the barrel C and is finally raised and discharged by the bucket A. As the piston rises, water flows into the space E below it through the annular passage F and ports connecting this annular passage with the spacer C. As the bucket A rises with it, water flows into the spacer C, to replace the water passing to the space E, through the port H and valve B. In this pump, two valves only are required, the valve B and the bucket valve. The piston bucket, pump-rod, and the block K carrying the valve B may be withdrawn together. If desired, a foot valve may be placed in the bottom J, and a delivery valve above the bucket A. The lower barrel and its sheath may be enclosed in an outer sheath open below.

Abstract: 1503519 Irrigation installation ETABS CARPANO & PONS 3 April 1975 [9 April 1974] 13704/75 Headings A1B and AID {Also in Division F2] Liquid delivery from sprinkler heads 12, 19 of a number of dispensing valves 9, 16 connected in cascade is remotely controlled by opening a gate valve 4 to begin sprinkling, and closing the gate valve to reset the dispensing valves at the end of the sprinkling operation. Each dispensing valve 9, 16 has sprinkler heads 12, 19 connected to first outlets 10, 17, and inlets 8, 15 connected by piping 7, 14 to either outlet 6 of gate valve 4 or second outlets 13, 20 of the dispensing valves. A water supply 2 is connected to the inlet 3 of the gate valve 4 provided with a solenoid-operated disc 26 for closing outlet 6. Closure of outlets 10, 17 occurs when sufficient water, derived from inlets 8, 15 via conduits 60 and flow regulators 62, accumulates in chambers 58 to depress flap? 50 against seats 53 by the action of pusher rods 57. The liquid-discharge orifice 22 allows leakage as soon as outlet 20 is opened; but no pressure drop occurs within pipes 7, 14 until outlet 6 of gate valve 4 is closed. At a particular value of pressure drop, each ball 70 compresses its spring 71 to place chambers 58 into communication with inlets 8, 15. Each pusher rod 67 then retracts under the action of springs 59, and flaps 50 close the outlets 13, 20 under the action of each bias 51. In an alternative embodiment (not shown), the orifice 22 may be replaced by an orifice in gate valve 4. The valve 4 is then constructed so that the orifice opens simultaneously with the closure of opening 23 to place outlet 6 into communication with the exterior. Operation of the gate valve 4 may be controlled by a clock 5, or a clock co-operating with a humidity sensor, a supply tank liquid-level detector, a rainfall detector, and a photosensitive detector. The gate valve may alternatively be a manually controlled tap or a valve of the type described in specification 1439913. The installation may be sited above or below ground level.
