Title: A device for quantitatively forming and dispensing a mixture of two liquids in predetermined relative amounts
IPC: G05D11/00
Filed: 1953-03-27
Abstract: 725,847. Proportionate mixing of liquids. ZANCANGELONI PETROLI SOC. PER AZIONI. March 27, 1953 [Nov. 20, 1952], No. 8523/53. Class 86. A device for quantitatively forming and dispensing a mixture of two liquids in predetermined relative amounts comprises two mixing chambers each associated with a smaller capacity adjustable metering chamber, so arranged together with pressure actuated valve means, that when one mixing chamber discharges a mixture of the two liquids, its associated metering chamber receives a charge of a first one of the liquids, and the other metering chamber delivers a charge of the first liquid into its associated mixing chamber whilst the second liquid is also supplied to that mixing chamber, and when that mixing chamber is full, the valve means is operated to reverse the function of the respective chambers for a repeat of the whole operation. In the position of the parts of the apparatus shown in the Figure, a metering chamber 6 contains a first liquid received from a tank 3, and a mixing chamber 11<SP>1</SP> has commenced to deliver its contents to a discharge pipe 1, through a cylinder 23 and port 24. A pump 8 delivers a second liquid from a tank 9 into the mixing chamber 11 and builds up an air pressure which, acting through a tube 12, forces a piston 2 rapidly to the left. hand end of a cylinder 2<SP>1</SP>, having overcome the resistance of a spring catch 18. A port 14 in the piston 2 is brought into alignment with ports 5 and 34 in the metering chamber 6 and mixing chamber 11, and the contents of the chamber 6 flows into the mixing chamber 11 A slot 15 in the piston 2 opens a passage between the tank 3 and metering chamber 6<SP>1</SP>, so that the metering chamber 6<SP>1</SP> receives a charge of liquid from the tank 3. The second liquid continues to be pumped into the mixing chamber 11 until a float 19 closes the port 34, whereupon a pres sure is built up in the chamber 11 by the pump 8 and this pressure forces a piston 17 to the left By this action pistons 10, 10<SP>1</SP> are moved to the right so that the chamber 11 communicates with the outlet 1 and delivers its contents there through, and the pump 8 commences to delive liquid from the tank 9 into the metering cham ber 11<SP>1</SP>, the action continuing with the same sequence of operations just described. The volume of the metering chambers 6, 6<SP>1</SP> is adjust able by means of displaceable pistons 7, 7<SP>1</SP> The movement of the piston 17 causes operation of a metering device 37 by which the amount of discharged mixture can be read.

Title: Improvements in machines for producing packages of wool, yarn and like strands
IPC: B65B9/213
Filed: 1939-03-18
Abstract: 526,520. Bundling machines. SHEPHARD, SPRAY & HADDON, Ltd., and SPRAY, E. A. March 18, 1939, No. 8722. [Class 94 (i)] Relates to machines such as are described in Specification 419,578 for producing packages of wool, yarns &c. According to the invention, a machine comprises means for gripping a bunch of yarns and withdrawing the yarns from a supply bobbin and means for pushing or propelling the bunched yarns towards a wrapping position, in combination with co-operating means for gripping and conveying the wrapped yarns intermittently to a cutting device. A number of yarns 10, Fig. 1, are led through a tubular guide 11 towards a spool 13 on which a roll of paper is mounted. The paper and the yarns are fed through the machine by spaced horizontally reciprocable gripping devices 35, 36. The paper passes through an arcuate slot 21, Fig. 12, in a plate 16, the yarns passing through an adjacent circular guide, and next through a slot 22 of greater curvature in a plate 17. At the next folding station, concentrically disposed guides 23, 24 cause the paper to encircle the yarns completely. Overlapping of the edges of the paper is effected by means of a deflector plate 25 extending between the guides. An adhesive strip 27 is fed from a reel 28 past a guide roll 29 and moistening pad 34 through a slot 30 in the tube 23 coinciding with a position of the overlap, and secures the the edges together. Adhesion may be ensured by means of an electric heater carried by the tube 23. The gripping devices 35, 36 are mounted for simultaneous movement to the left, Fig. 1, when closed in upon the yarns, and return when in the open position. The grippers 35 engage the yarns before they reach the wrapping station and withdraw them from the supply, and the grippers 36 engage the wrapped assembly, draw them through the folding devices and feed them towards a cutter 70. The jaws 35 comprise spaced fingers 35a, Fig. 5, on members 42 adjustably mounted on carriers 43 pivoted at 37 on carriages 61 slidable on rods 62. The longitudinal movement is derived from rods 60 driven by a bellcrank lever oscillated from the main drive, and the jaws are opened and closed at the appropriate times by cams 40 on rods 68 having the necessary movements imparted thereto. The wrapped yarns are cut into packages of the required length by a rotating cutting-disc 70, as described in Specification 526,540.

Title: Electric pulse signalling system
Inventor: QUARMBY RAYMOND BARBER
IPC: G08C19/22
Filed: 1965-03-01
Abstract: 1,130,131. Measuring temperature electrically. ENGLISH ELECTRIC CO. Ltd. Feb. 25, 1966 [March 1, 1965], No. 8747/65. Heading G1N. [Also in Division H4] In a system for collecting information at a receiving station 5, information from a plurality of sources is transmitted via transducers 6, including thermocouples 15, and a common channel 7 as signals having a duration proportional to the amplitude of the output signals from the thermocouples 15. Details of one transducer 6 are shown. The common channel 7 comprises lines 8 to 12 and a group of lines 13. When information is required to be trahsmitted, a signal is sent to all the devices 6 via line 12 which sets the magnetic core of the type having a square hysteresis loop, of a device 26 in each transducer at saturation point, each signal from thermocouples 15 having charged a corresponding capacitor 18 accordingly. A signal on line 10 is then sent to all the devices 6 simultaneously which renders the transistors 27 conductive and the voltage across the capacitor 18 is applied to the winding 25 of the device 26 thus reducing the flux level of the core at a rate dependent on the applied voltage level. The signal on line 10 is arranged to exist for a predetermined short time and when it ceases the flux level in each core represents the output of the corresponding thermocouple. Diodes 41 to 44 are connected to different combinations of lines 13 for each device 6, the lines 13 normally being energised with positive potentials so that the diodes 41 to 44 conduct and all the transistors 39 are cut off. When it is desired to transmit to the receiving station 5 the value of the information stored in a particular core 26, the appropriate lines 13 are energized with negative voltages so that the diodes 41 to 44 are cut off and the transistor 39 conducts, causing diode 30 to conduct. In this way a predetermined voltage from voltage divider 32, 33, 34 is applied across winding 28 to drive the flux at a constant rate back to the saturation point. When the flux reaches saturation point the voltage across winding 28 will fall effectively to zero and the diode 30 will cease to conduct so that a voltage pulse of duration proportional to the magnitude of the input signal is produced on line 45 and transmitted via line 11 to the receiving station 5. The diode 46 prevents interaction between the various devices 46. The line 12 may be omitted and all the cores reset to saturation by energizing all the lines 13 simultaneously. In a modification suitable for small signal inputs, Fig. 2 (not shown) the voltage across capacitor (18) is supplied via an additional transistor gate and an amplifier to the winding (25) an additional winding on the core(26) providing negative feedback for the amplifier. A normally open relay contact may be connected in parallel with the additional transistor or it may be a field effect transistor to prevent any error due to its base emitter voltage.

Title: Improvements in or relating to garment strap fastening device and a buckle therefor
IPC: A41F11/02
Filed: 1946-04-18
Abstract: 636,890. Friction grip fastenings. BERGER BROS. CO. April 3, 1947, No. 9118. Convention date, April 18, 1946. [Class 44] [Also in Group VII] A buckle for a garment fastening device to be adjusted along a single strap comprises a frame including three parallel cross-bars, and a loop which is pivoted to the frame and has integral with, or secured to, it a clamping member, an edge of which co-operates with the centre cross-bar to grip a strap, said clamping member being actuated by the loop, and the arrangement being such that the operative edge of the clamping member swings from an open position on one side of a plane through the centre cross-bar and the pivot of the loop to a clamping position just on the other side of the plane, stop means then preventing further movement beyond such clamping position. The frame 10, Fig. 3, has an upper bar 11, an intermediate bar 12 provided with teeth 13, and a shorter lower bar which is connected to the frame by upwardly projecting legs 15. A loop 16 of wire stock is secured rigidly to a link 17, part of which is wrapped round the bar 14 so that it can swivel thereon ; projecting upwardly from and integral with the link 17 is a clamping member 20 provided with a bent upper end 21. The strap 25 passes from the rear of the bar 11 over the bar 12, and then back between the teeth 13 and the end 21 of the clamp, its free end lying behind the loop 16 ; tension on the strap causes the bent upper end 21 to move to the clamping position, Fig. 2, i.e. past a dead centre position, further movement being limited by the engagement of the sides of the clamp 20 with the legs 15 of the frame 10. To open the clamp sufficient force must be exerted to move the end 21 to the right past the dead centre position causing increased compression of the strap ; this is effected by swinging the loop 16, and hence the clamp 20, about the bar 14. In a modification, Fig. 7, the loop 26 is of sheet metal and has a clamping bar 32, for co-operation with the cross-bar 29 of the buckle frame, and a cross-bar 31 which swivels in a link 33 rigid with the lower bar 30 of the buckle frame.
