Title: Improvements in apparatus for testing metal coins, tokens, or the like
Filed: 1934-10-01
Abstract: 423,298. Testing coins ; magnetic separators. LYTTLE, R. J., 53A, Park Avenue, Ashfield, near Sydney, Australia. Oct. 1, 1934, No. 28060. [Class 27] [See also Group II] A coin-testing apparatus comprises a casing 1, Fig. 1, containing an electromagnet 2, Fig. 4, having a primary winding 3 connected to a source of alternating or interrupted current, and a secondary winding 5, the coils of which are wound so that the induced current in one coil is opposed to that in the other. In the circuit of the coils 5 is a measuring instrument, such as a milli-ammeter, which is calibrated by placing genuine coins 17 in proximity to one pole of the magnet 2 and obtaining the marks 10 on a dial 8 to which a pointer 11 reaches, when a switch 24 is closed. The circuit is adjusted or tuned, so that the pointer remains at zero in the absence of a coin, by sliding the coil 5 or by a soft iron member 12, a fine tuning being obtained by an iron member 14 having an adjusting screw 15. To test a coin, the switch 24 is closed and an armature 20 having two pins is attracted into a shoot 18 in which the coin is inserted. The coin rests on the pins in proximity to one of the magnet poles and the position of the pointer on the dial 8 is observed. If the coin is not genuine the pointer will not reach the proper mark 10 for that denomination of coin. When the switch 24 is opened, the coin drops down to the operator. When a very delicate instrument 7 is used, a rectifier is provided in the circuit 5. For automatically separating genuine from spurious coins subjected to the test, the coins 17 roll from a hopper 30, Fig. 7, under a rotating wheel 35 which prevents jamming, to a vertical shoot 36 where they are received in pockets of a rotating wheel 37. While in the pockets, the inductance test is applied and if the coin is spurious it passes through a branch shoot 42 to a receptacle 58. If the coin is genuine the entrance to the shoot 42 is blocked by a rocking member 45 and the coin passes down a shoot 60 from which it is passed by a wheel 61 to a receptacle 69, each coin in its passage rocking an arm 65 and through a link 68 actuating a counter. The wheels 35, 37, 61 are driven by an electric motor 71, Fig. 11. When the coin is genuine, the pointer 11 reaches a contact 55 on the dial 8 and closes the circuit of a relay 53, thereby closing at 52 the circuit of an electromagnet 48. The consequent movements of its armature 47 rocks, through a link 49, the member 45 and causes an abutment 44 thereon to close the branch shoot 42. The armature 47 also closes a contact 74 and cuts out a resistance 72 in the circuit of the motor 71 so that the wheels 35, 37, 61 are driven at a greater speed, and enable genuine coins to be dealt with expeditiously. The sides 38, 63 of the shoots 36, 60 are resilient to prevent jamming.

Abstract: 700,363. Regulating pumps. THOMPSON BROS. (BILSTON), Ltd., and COOMBES, J. R. Nov. 1, 1951 [Nov. 18, 1950], No. 28238/50. Class 102 (1). [Also in Group XXIX] A by-pass valve 19, Fig. 1, for a pump 10 in a liquid supply system, e.g. an aircraft fuelling system, is opened against an adjustable loading spring by pressure prevailing at the discharge point 16 of the delivery line of the system. In one embodiment, the valve comprises a rotary plug 27, Fig. 3, controlling communication between the delivery side of the pump connected to a chamber 45 and the suction side connected at 43. Communication is prevented by a spring 32, Fig. 2, until the discharge point pressure acting on a diaphragm 22 reaches a predetermined value. The spring is adjusted by a handle 37 via a screwed rod 34 which drives a pointer 41 round a scale 41x indicating the pressure at which the valve will open. In another arrangement, discharge point pressure acts on one end of a hollow piston having ports in its wall which control communication through the piston between the delivery and suction sides of the pump. The spring adjuster incorporates a linearly moving pointer to indicate opening pressure.

Title: An improved system for the detection of smoke, or fine particles carried in suspension in a gas or vapour
IPC: G08B17/10
Filed: 1921-10-25
Abstract: 191,856. Marks, E. C. R., (Kidde & Co., Inc., W.). Oct. 25, 1921. Smoke-pipe alarm systems. - In a system for detecting smoke &c. and in some cases for extinguising fires, in ships, buildings &c., a beam of light is projected through, into, or across the mouths of pipes, through which air &c. is drawn from various compartments. The light is normally invisible from the point of observation, but serves to illuminate any fine particles that may be in the air &c. Steam &c. is admitted into any compartment, through a corresponding pipe, when smoke is detected. A pipe 1, Fig. 1, having an open hood 4 near the top of a compartment, leads to a control cabinet 2 provided with a hinged door 3. A valve 5 in each pipe 1 permits steam from a main pipe 7 and a header 6 to enter the corresponding compartment; or carbon dioxide &c. may be supplied through a pipe 9. Above the valve 5, a pipe 11 leads to a detector cabinet 12 having an observation glass panel 13. A fan 16a draws air from each compartment through the pipes 1. Each pipe 11 leads to a tube 17, and a beam of light is projected so as to be ordinarily invisible, but, when smoke is present, the particles become illuminated. Fig. 2 shows four tubes 17, light beams from an electric bulb 18 being projected through the tubes by lenses 20 and mirrors 19. A glass diaphragm 21 may be employed to exclude dust. Each tube is made, preferably, of two telescopic sections locked by a clamp 22. Alternative arrangements of the tubes 17 are described. In one arrangement, they are disposed in concentric circles with the source of light in the centre. In another arrangement, the beam is projected downwardly into the tube, and, in a further arrangement, the beam is projected across the mouths of several tubes. In another modification, a continuous pipe leads from the tube 17 to the suction fan, the smoke being observed through a glass section in the pipe. The detector cabinet 12 is preferably provided with a section 28 above the glass 13 to reduce the possibility of direct rays striking the eye. Devices 29, 30, and 31 are provided for drainage. The discharge from the fan 16<a> passes through louvers 32; or, in the case of a noxious gas, the arms of a lever 33, operated by a handle 34, may actuate two slides 35, 36 so as to close the louvers 32 and open a discharge leading to the atmosphere. A smoke valve 14 located in the pipe 1, Fig. 7, is closed by a spring 43 operated by a lever 15 carrying a cam 44. The lever 15 is located behind and adjacent to the door 3 of the control cabinet 2. Normally, the smoke valve 14 is open and the steam valve 5 closed, but, when the observer detects smoke issuing from one of the tubes 17, he notifies the operator at the control cabinet 2, who opens the door 3 and raises the lever 15 of the corresponding smoke-valve 14 to close it. The steam-valve 5 is then opened. permitting steam to enter the compartment.

Patent GB-1410169-A (GB)
Title: Method of making composite layered structures by spraying
IPC: B29C41/08
Filed: 1971-06-17
Abstract: 1410169 Moulding ceramic compositions JOHNSON MATTHEY & CO Ltd 15 Sept 1972 [19 June 1971] 28393/71 Heading B5A [Also in Divisions B2 B3 H1 and H5] A composite layered structure comprising alternate layers of electrically conducting and electrically non-conducting material is made by spraying a material of one type from a source on to a substrate, simultaneously spraying a material of the other type from a different source and displacing the substrate and the sources relative to one another so as to cause one layer of material to at least partially overlay the other layer. Prior to spraying, the substrate may be roughened by grit-blasting and may be provided with a release layer of salt crystals by spraying of salt solution to allow subsequent removal of the composite from the substrate. The coating materials may be gold and barium titanate ceramic respectively and may be applied by flame or plasma-arc torch, the materials being fed thereto in the form of a rod or wire or as a powder which may contain an organic binder. Spraying may be repeated to build up further layers, the torch optionally being played over the deposited coating prior to further spraying. Spraying may be masked or interrupted at intervals over the substrate surface and the composite structure so formed cut up to produce a number of smaller layered structures. The substrate may be a tape or sheet which is displaced relative to the sources or may be a disc which is sprayed to produce a spiral coating by radial traversing of the sources. The substrate may also particularly be a cylindrical mandrel 10 of aluminium, iron or barium titanate ceramic which is sprayed firstly with salt solution and then with alternate helical bands of gold, M1 and M2, and barium titanate, C1 and C2, by means of four equally spaced spraying devices M and C. The substrate may itself be of electrically conducting material to constitute or form part of one electrode of a capacitor, ceramic material being sprayed thereon and being overlaid by a layer of conductive material which constitutes or forms part of the other electrode. Alternatively, alternate layers of conductive material may be electrically connected to form one electrode and the remaining layers of conductive material connected to form the other electrode. Terminal blocks of sprayed metal may be built up at each end of the mandrel or, by masking or interruption of the spraying torches, the structure may be formed with exposed portions of metal layers which may be connected by dipping in molten solder. The layered composite may be used as a heating element assembly useful as a furnace heater comprising a mandrel or support carrying a spirally wound conductor. Such a heating element may be incorporated in or attached to the base of a crucible for use in an induction furnace.

Patent GB-341846-A (GB)
Title: Improvements in and relating to phonographs and the like
IPC: G11B17/16
Filed: 1929-09-20
Abstract: 341,846. Gramophones. JONES, A. D., 247A, St. Vincent Street, and SMITH, S. J., 39, Randolph Road, Broomhill, both in Glasgow. Sept. 20, 1929, No. 28533. [Class 40 (ii).] Multiple machines; ,' returning sound-box to starting point sound boxes, arrangement of.-In a magazine gramophone, the record changing mechanism and the stylus re-positioning mechanism are driven by a separate motor which is started up when the stylus reaches the end of the record groove. As shown, a motor 4, Fig. 3, which continuously drives the turntable 1 also rotates a threaded spindle 2 so that a member 7 engaging the thread groove moves at the same rate as the tone arm 8 during reproduction. The tone arm pillar 9 carries a fork 11<1> having contact pins 12 adjacent the member 7. When the stylus reaches the end of the record groove the relative movement of the members 7, 8 causes the former to contact one of the pins 12 to close a relay operating the switch of the motor driving the record-changing mechanism. The said motor rotates a spindle 15, Fig. 4, carrying three cams 39, 40, 41 and a pin 24. The pin 24, and a cam 25 on the cam 39, respectively oscillate and raise and lower the record change-arm 20 so that it moves to disengage a pin 28 thereon from the central hole of the played record and engage the hole of the uppermost record on the magazine platform 21 and to slide the fresh record on to the turntable 1, the played record being pushed into a receiver 30 by a pin 29 on the arm 20. The pin 24 engages a slotted link 23 on the changearm pillar 22 the angular movement being limited by a detent pawl and stop. The platform 21 is carried by a tubular stem 31 through which passes a rod 34 engaging the central holes of the records and a spring 36 moves the platform 21 so that the uppermost record is ready for transfer to the turntable. Rollers 38 on a pivoted arm 37 lightly press upon the top record. The cam 39 operates a connection 43 so that at the proper times the arm 8 turns about a bearing 44 to raise the stylus from the played record and lower it upon the fresh record. The arm 8 is swung outwardly by the cam 41 which operates a connection 54 secured to an arm on the tone-arm pivot pillar 9. The outward movement of the arm 8 is limited by a stop 62 carried by a lever 49 and engaged by an arm 55 on the pillar 9. The position of the stop is adjusted to suit the size of record used. For this purpose the lever 49 has a pin 50 projecting through an arcuate slot 51 in the machine casing 10 and a record in passing from the magazine to the turntable engages the pin 50 to position the lever 49. The lever 49 is held in the adjusted position by the engagement of a brake shoe 47 with a block 48 on the lever 49, the shoe 47 being operated by a cable 46 controlled by the cam 40.

Title: Recovery of sulphur
IPC: C01B17/06
Filed: 1932-10-13
Abstract: <PICT:0408669/III/1> In the recovery of sulphur from pyrites and other metallic sulphides, the labile sulphur atom is distilled off and the resulting ferrous sulphide in finely divided condition is roasted while suspended in a countercurrent stream of oxidising gas to produce sulphur dioxide which passes into contact with a powdered carbonaceous reducing agent, preferably coke, to produce elemental sulphur.  Powdered ore and coke are fed from a hopper 2 by a worm 3 into the top of a furnace 1 in counter-current to air &c. entering by tuy<\>geres 5.  Prior to the entry of the charge, the furnace is heated to 850 DEG  C. by oil burners inserted at work holes 12 and the air is preheated by the hot metallic oxides, e.g. Fe2O3 or Fe4O5, withdrawn by the conveyer 9.  Any labile sulphur is driven off in the upper part of the furnace and the sulphur dioxide produced by oxidation in the lowest part of the furnace is reduced by the descending coke, and maybe by the sulphide, in the intermediate zone which is maintained at 800 DEG  to 950 DEG  C.  The gaseous products of reaction, including sulphur vapour, carbon monoxide, sulphur dioxide, hydrogen sulphide, and perhaps carbon oxide sulphide and carbon bisulphide, leave by a pipe 7 at 350 DEG  to 450 DEG  C. and, after passage through a dust collector, are led to a catalyst chamber, containing, e.g. bauxite, where interaction between the gases to produce further sulphur is effected.  Supplementary sulphur dioxide and carbon monoxide may be provided if required.  The gases then pass to a condenser which may be in the form of a waste heat boiler.

Patent GB-526094-A (GB)
Title: Improvements in or relating to control means for hoists and the like
IPC: B66B1/08
Filed: 1939-02-06
Abstract: 526,094. Lifts ; winding apparatus ; rope railways ; railway signals. JONES, H. R., and A.C.E. MACHINERY, Ltd. Feb. 6, 1939, No. 287/38. [Classes 78 (iii), 78 (v), 104 (ii) and 105] Relates to control means for hoists such as lift cages or haulage trucks of the kind in which control movements are transmitted from the hoist to a remote control lever for starting and stopping the winding gear by means of a cable which extends along the whole length of travel of the hoist and has running engagement with a device on the hoist which can be operated manually to alter the effective length of the cable by producing a kink or bend in the cable and thus operate the remote control lever in any position of the hoist. According to the invention, the control handle on the hoist is coupled to the part having running engagement with the cable through a clutch controlled by a trip mechanism which is operated automatically when the hoist over-runs a pre-determined extreme limit of travel to disengage the clutch so that the operator loses control and the remote control lever is then moved by a spring or weight to a position for stopping the winding gear to bring the hoist automatically to rest. In the form shown applied to a lift cage, the control cable 1, fixed at one'end and connected at the other to a weighted lever 7 controlling the winding gear, engages between pulleys 8 on a plate 3 pivotally mounted in the cage. To effect movement of the cage, the plate 3 is rotated through 90 degrees by means of the hand lever 14 and held in this position by the operator. This movement of the plate 3 effects a kink in the cable and raises the control lever 7 to a position in which it causes engagement of a driving clutch. The plate 3 is mounted on a shaft 11 connected with the handle 14 through a friction clutch comprising a disc 15 freely mounted on the shaft 11, and a disc 16 slidably mounted on the shaft and coupled thereto by a feather. The clutch is controlled by a toggle comprising pairs of links 29, 30, the links 30 having lateral extensions which are united at 36 and coupled to an operating lever 37 by a pin- and-slot connection 38, 39. Should the operator not release the handle 14 when the cage reaches its upper or lower extreme limits, a fixed stop 46, Fig. 6, in the well engages a trip lever 43 so as to rock an arm 42 on the shaft 41 of the toggle operating lever and break the toggle. This releases the clutch disc 16 and disconnects the handle 14 from the shaft 11. The control lever 7 is then returned to the stop position by its weight 10 and the cage brought to rest. The handle 14 is connected to the disc 15 by a spring-pressed plunger 21 which engages teeth 22 on the disc, the plunger being controlled by a grip lever 24. In a modified arrangement of trip mechanism for use at the bottom of the lift well, the stop member is mounted so that it can rock in an upward direction to a limited extent.
