Title: Automatic telephone answering device
IPC: H04M1/64
Filed: 1971-06-04
Abstract: 1354128 Substitution apparatus PIONEER ELECTRONIC CORP 4 June 1971 [5 June 1970] 19083/71 Heading H4K In a telephone answering machine a winding of a drive motor of a magnetic medium is arranged to pass current at all times during normal working, and a detector responds when the current ceases preventing the machine from responding to a call or causing the machine to restore to the "on hook" condition. In the answering only machine shown ringing signals on a line 11 are rectified at 12 smoothed at C3 and charge up a capacitor C4 until after a predetermined number of ringing signals a transistor Tr 1 cuts off turning on a transistor Tr 2 which energizes a relay Y1 causing its contacts Y11 to Y14 to change over from the position shown. A capacitor C5 maintains the relay Y1 energized. The line is looped and a motor 15 is energized to transmit a message from a tape 17 over the line. A high resistor R7 is connected across the motor energize contact Y13 such that under all normal conditions a current passes through the winding of the motor. A detection circuit 22 responds if this current ceases due to a break in motor winding switching a transistor Tr 4 to conduction and preventing energization of or causing the release of relay Y1. If when the motor contact is closed the current is abnormally high the current in secondary winding 212 of a transformer 21 is sufficient after rectification at D3 and smoothing at C6 to trigger a Zener diode D5 and energize a transistor Tr 5 of a bi-stable Tr 5, Tr 6 similarly causing the release of relay Y1. Capacitor C7 is provided to absorb the mementary heavy current which flows on start of the motor under normal conditions. If the machine is also adapted to record an incoming message, detection circuits can be provided to monitor the current through each motor.

Title: Improvements in or relating to liquid-liquid extraction tower
IPC: B01D11/04
Filed: 1949-07-20
Abstract: <PICT:0664872/III/1> Apparatus for countercurrently contacting and concurrently settling partly miscible or immiscible liquids of different densities and particularly applicable to the solvent extraction of petroleum oils by means of phenol, comprises a vertical tower 10 having a number of plates 4, 5 and 19 arranged at spaced intervals and extending across the whole width of the vessel.  The plates comprise a central portion impervious to liquid, which is flanked by a perforated stepped-up portion (15 and 17 of plates 4 and 5 respectively) and a perforated stepped-down portion (16 and 18 of plates 4 and 5 respectively).  The stepped portions are connected to the main body of the plate by vertical walls 7, 8 and 9, which are extended beyond the plane of the main body to provide weirs.  The stepped-up and stepped-down portions of adjacent plates are arranged at opposite ends to each other and provide a confined zone in which the fluids are mixed (e.g. between 16 and 17), a large zone in which the mixed fluids separate (e.g. between unperforated portions of 4 and 5) and a pressure-developing 15 and 18).  The phenol is introduced to the zone (e.g. between the perforated portions top of the tower through the line 2 and, being heavier than the petroleum oil, will tend to flow downwards in countercurrent to the oil introduced to the bottom of the tower through the line 11.  Phenol builds up on the lowermost steps of the plates (e.g. 16 and 18 of plates 4 and 5) and oil beneath the uppermost steps (e.g. 15 and 17 of plates 4 and 5), until the head is sufficient to jet the phenol downwardly and the oil upwardly. Baffles 6 may be provided adjacent the weirs 7, 8 and 9 for increasing the efficiency of the separation of the phenol-oil mixtures formed on the jetting stage.  The provision of weirs is optional.

Title: Improvements in and relating to safety devices for combustion apparatus
IPC: F23N5/18
Filed: 1961-05-29
Abstract: 978,083. Furnace shut-down systems; supplying liquid fuel to burners. G. FUCHS. May 29, 1961 [May 27, 1960], No. 19271/61. Headings F4B and F4T. A heating unit incorporating a burner includes a temperature-responsive safety device for interrupting the fuel supply to the burner if the device develops smoke or soot due to an insufficient supply of combustion air. Oil is supplied through a pipe 7 to a burner 6 in a perforated chamber 4. Primary air is drawn by a fan 11 through openings 23 and 13 in two outer shells 22 and 9 separated by an annular thermally insulating packing 21 and forced through perforations 3 in chamber 4 to the burner. Burning gases pass through an opening 15 in the burner chamber and thence through an inlet 16 into the combustion chamber 18 of a boiler furnace provided with flue draft-producing means (not shown) which cause secondary air to be drawn into the combustion chamber in the direction of arrow 28 from an annular space 27 between the burner chamber and combustion chamber. A conduit 29 containing a bi-metal switch 32 is disposed in the annular packing 21 and connects the secondary air path to the suction side of the fan 11 so that some air is drawn through it as part of the primary supply, as shown by arrows 34 and 35. In normal operation, the flow of outside air through conduit 29 and heat conducted to it from the burner chamber maintain the bimetal switch at a steady temperature. At this temperature the bi-metal switch is closed as also in normal operation are switches 53, 55 and 58 completing circuits which energize the fan motor 12 and hold open an electromagnetic fuel valve 63. If the motor 12 should break down the flow of air through conduit 29 will cease and the temperature of the bi-metal switch will rise. If the smoke tubes of the boiler become blocked or the flue draft-producing means cease to function, smoke and hot gases will pass through the annular space 27 and some will enter conduit 29, also raising the temperature of the bi-metal switch. The raised temperature of the switch causes it to open operating a relay 56 which opens switches 55 and 58 to stop the fan motor 12 and to allow the electromagnetic switch to be closed by the action of a spring 69, thus shutting-off the fuel supply to the burner. To restart the furnace the switch 57 is pressed, causing the relay 56 to close switches 55 and 58.

Abstract: 503,948. Slicing-machines. BAUDUR, A. July 12, 1937, Nos. 19334 and 19335. Void. Convention dates, July 11, 1936 and Dec. 1, 1936. [Class 28 (ii)J In a slicing-machine, the oscillating spiked slice conveyer of the slice-stacker is mounted on a shaft carrying a bevel wheel 5a on which a cam 25 is secured and which is driven by a bevel pinion on a shaft 45 driven by a rack on the reciprocating carriage engaging a pinion 46. The discharge fly is mounted on a shaft 34 which is connected by toothed quadrants 32, 28 to a shaft 27 which is urged by a spring 30 to swing the fly through its discharging motion. The fly is raised to its slice-engaging position by a roller-ended arm 47 on the shaft 45 engaging a lever 50 on the shaft 27, the fly being locked in this position by a latch lever 18 which is released by the cam 25 engaging a roller 22. The toothed quadrants may be replaced by a roller and slot connection between the levers 32, 28, in which case a buffer-stop for the lever 28 is provided on the casing 36. The member 61 for impaling the slices on the conveyer comprises a curved plate, slotted for the passage of the spikes, and detachably secured in a bracket 60 on the casing 36. The slots may open into the edge of the plate. The conveyer comprises straight and bent spikes 1, 2 which are secured between spacers 4 on rods 3, the whole being clamped between top and bottom plates 5 by nuts 6, a tube 7 around the central conveyercarrying shaft maintaining the correct spacing of the plates 5. The conveyor is clamped on its shaft by a cap 8 and a locking-screw 9. In a modification, the shaft projects only slightly above the casing 36 and the conveyer is mounted on a horse-shoe shaped bra ket which is secured to the short shaft by a milled knob. In a further modification, a circular ramp, positioned beneath the wheel 5a, is carried by a lever keyed to the fly shaft 34, and is acted upon by a roller, mounted on the underside of the wheel 5a whereby the ramp is, at times, depressed to raise the fly to its slice-receiving position.

Patent GB-1065357-A (GB)
Title: Improvements in or related to electrogravitational fluid treatment devices
IPC: C02F1/46
Filed: 1964-05-11
Abstract: An electrogravitational device comprises a container 10 having sides 11, 12 from which extend at an acute angle ion selective membranes 28, 29, means 34 for introducing fluid to be treated into the container, means 36 for withdrawing the product stream and means 30, 31 for withdrawing fluid from the container from the sides within the acute angles formed by the membranes.  In the embodiment shown the ends of the container are formed by membranes 14 and 15 held in place by electrode-compartment-forming plates 16, 17 platinum wire mesh electrodes 18, 19 being placed within the electrode chambers thus formed.  <PICT:1065357/C6-C7/1> In operation as shown cation permeable ion selective members are used, with the result that the fluid above the membranes becomes more concentrated and hence more dense than the fluid below the membrane.  The dilute layers thus move upwards along the lower surfaces of membranes and thus dilute solution is drawn off via the outlet 36.  The more concentrated fluid slides down the upper surface of the membranes and is drawn off via outlets 30 and 31. The container 10 may be formed of rigid plastic tubing containing slots into which the membranes are inserted, and may be provided with an outer jacket which serves to collect the fluid drawn off via the outlets 30, 31.  In other embodiments the membranes may incline downwardly; may have parallel to each a plurality of progressively smaller membranes thus forming a group of membranes in each stage Fig. 8 (not shown); or may be formed of one continuous membrane formed into a zig-zag shape, and having holes to permit the flow of fluid there-through. The membranes used may be anion permeable, the positions of cathode and anode then being reversed.

Title: Improvements in or relating to adhesive applying apparatus
IPC: B65C9/22
Filed: 1947-07-22
Abstract: <PICT:0641254/III/1> <PICT:0641254/III/2> <PICT:0641254/III/3> <PICT:0641254/III/4> An adhesive applying apparatus comprises a table with a surface to which adhesive is supplied, an equalizing member mounted in spaced relation to said surface and constructed to spread the adhesive across a substantial portion of said surface, a film-forming member having an edge portion mounted in spaced relation with said surface, said edge portion and said film-forming member forming a film passage of predetermined dimensions, and means to move said table relative to said equalizing member and said film-forming member to spread the adhesive and form on at least a portion thereof a film of predetermined thickness.  Referring to the drawings, a table 10 carried by a drive-shaft 10a presents objects 9 successively at an adhesive applying station 8, which comprises an adhesive carrying pan 11 in which is partially immersed a supply disc 16 rotating about a horizontal axis through shaft 17 and pinions 22, 23 by means of shaft 20 which is driven by main drive-shaft S through chain 25 and sprockets 24 and 25a.  This driveshaft is also connected with shafts 10a and 36.  An adhesive film-forming table 26 within pan 11 is rotated about a vertical axis by shaft 27 meshing with shaft 32 which itself meshes with shaft 36.  In operation, adhesive on supply disc 16 is removed by blade 37 on to the periphery of supply disc 16 where equalizing blade 38 distributes it across the disc surface and film measuring blade 39 forms it into an accurately distributed film of the required thickness, directing the excess off the edge back into the supply tank.  In order to transfer this film to an article shaft 36 carries two pairs of radially extending arms constituting bearings for plungers 45 urged downwards by collars 47, springs 48 and limiting collars 46.  At the lower end of each of the plungers 45 is an adhesive applying head 49 which picks up adhesive from disc 26 and deposits it on the objects 9.  Shaft 36 is vertically reciprocated in timed relation with its rotation by means comprising a rocking arm 50 pivoted on stationary posts 51 by pins 52 and carrying at each end a roller 53, the end fitting into flanges 54 being bifurcated and carrying two such rollers. At the other end the arm 50 engages a barrel cam 55 on the driving shaft S, so contoured as to rock the arm 50 and so move shaft 36 upwards and downwards to such an extent that rotation of the shaft is stopped by the disconnection of pinion 35 with idler pinion 34, so that heads 49 contact disc 36 while it and table 10 are at rest and lose contact before the disc and table resume motion.  A different type of transfer head may be used to transfer adhesive to the shoulder of a bag before pressing over on to the shoulder the folded lip of the bag and this apparatus may then be used in a bag closing machine of the type described in U.S.A.

Title: Improvements relating to motor vehicle sprag devices
IPC: B60T7/12
Filed: 1936-07-15
Abstract: 478,507. Preventing reverse movement of motor vehicles. STANCLIFFE FREE-WHEELLNG, Ltd., and WARWICK, A. J. July 15, 1936, No. 19684. Addition to 437,132. [Class 103 (i)] The sprag described in the parent Specification is modified in that it is not essential for forward gear to be engaged to enable forward movement of the vehicle to restore the energizer to operative condition. The detent 14 adapted to engage a ratchet wheel 13 to prevent reverse movement of the vehicle is also adapted to rest on the edge of a disc 19 which is of such a, diameter as to maintain the detent out of engagement with the wheel 13. The disc 19, frictionally gripped to the vehicle transmission shaft 8 by discs 25, 26 and a spring 24, is allowed limited movement relative to the shaft by stops 20-22 and has a notch 23 adapted to coincide with the detent 14 in mid-position and allow engagement of the pawl and ratchet wheel. In its extreme positions the disc 19 prevents their engagement. Thus in forward movement of the vehicle the detent and ratchet are disengaged but on reverse movement of the vehicle in the direction shown by the arrow engagement is allowed. If the vehicle is to be reversed, engagement of reverse gear disengages the detent by means of the selector rod 18 and reverse movement of the vehicle moves the disc 19 to its other end position so as to maintain the pawl disengaged after reverse gear has been disengaged and until the vehicle again moves forward. Specification 478,506 is referred to.
