Abstract: 1,187,190. Electric furnaces. D. W. GROOM. 8 Nov., 1968, No. 53151/68. Heading H5H. [Also in Division F4] An electric furnace for heating or vaporizing fluid, gaseous or solid materials comprises a container C<SP>a</SP> housing a vessel V<SP>a</SP> into which the material is supplied through a tube 24<SP>a</SP> and discharged through a line 22<SP>a</SP>, the outer wall of which vessel being heated by a heat sink mass of metal, e.g. lead, within the container having a melting point below and a vaporizing point above the operating temperature of the furnace, which metal is made molten by an electric resistance heater element H<SP>a</SP> disposed adjacent the vessel and operative to create convection currents in the molten metal to enhance heat transfer.

Abstract: 1,146,070. Carrier bags. WINDMÍLLER & HÍLSCHER. 29 Nov., 1966 [3 Jan., 1966], No. 53329/66. Heading A4G. A carrier bag has handles formed from strips of paper (2) having a reinforcing layer of woven textile fabric (3) bonded to or embedded in it, the fabric layer (3) having a width at least equal to that of the handgrip. The strip is folded, as at 11 or 12, into a U-shape and is adhesively secured at its free ends to the outside of the bag. Reinforcing strips 15 or sheets 16, 17 are secured to the inner walls of the bag. The reinforcing strip may extend around the complete periphery of the bag top.

Patent GB-1378065-A (GB)
Title: Heart pacers
IPC: A61N1/365
Filed: 1972-11-20
Abstract: 1378065 Heart pacemakers AMERICAN OPTICAL CORP 20 Nov 1972 [19 Nov 1971] 53593/72 Heading A5R A demand pacer comprises means for continuously monitoring the heart of a patient to provide a signal indicative of the average natural heart-beat rate of the patient and means responsive to the signal for providing a stimulation impulse to the patient when an interval corresponding to the average natural heart-beat rate is exceeded. A naturallyoccurring heart beat is detected by heart-beat detector 45 which provides an input to rate control 46 through OR-gate 70 and resets the timing circuitry in control 46 with each natural heart beat. Natural heart beats cause multivibrator 40 to provide rectangularly-shaped pulses which are averaged by capacitor 26 and resistor 27. A further capacitor 22 and resistor 23 are connected to capacitor 26 through diode 24. Capacitor 22 is also connected via diode 21 with zener diode 20 the voltage of which is selected to provide a desired minimum frequency of oscillator 41 which controls a stimulating pulse generator 42. Due to the opposed diodes 21, 24 the voltage on capacitor 22 rises to the larger of the voltage on capacitor 26, which is indicative of natural heart-beat rate, and breakdown voltage of zener diode 20. If the heart fails, capacitor 26 discharges through resistor 23. The voltage on capacitor 22 is fed to buffer amplifier, comprising transistor 16 and resistors 17, 18, providing a control voltage for oscillator 41 which comprises resistor 15, capacitor 14, transistor 13 and resistors 10-12. When the voltage on capacitor 14 reaches that established by resistors 10, 11, transistor 13 conducts and capacitor 14 discharges to pulse generator 42 which stimulates the heart. Capacitor 14 is also in parallel with the collector-emitter of transistor 28 which is turned on via OR-gate 70 by natural or stimulated heart beats, so that when a natural heart beat occurs capacitor 14 discharges before the voltage or it reaches the threshold value determined by resistors 10, 11 so that the heart is not stimulated. Pulse generator 42 also provides an input for blanking circuitry 44 to prevent detection of stimulated heart beats by detector 45.

Title: Apparatus for making support material from metal wire and cord of  paper or paper-like material
IPC: D07B5/00
Filed: 1971-11-19
Abstract: 1427312 Net making; metallic fabrics SLUMBERLAND (DEVELOPMENTS) LTD 19 Feb 1973 [19 Nov 1971] 53770/71 Headings D1K and D1R Specification 847432 describes an apparatus for making nets comprising longitudinal cords. e.g. of paper, linked by transversely extending cords which piece the intermediate longitudinal cords and are wound around the marginal (selvedge) longitudinal cords. In this specification the marginal cords are of metal wire wrapped with paper or other fabric and the apparatus includes means for wrapping a continuous length of the wire and supplying the wrapped wire to the net forming section at an appropriate rate. Preferably the rate at which wire 12 is wrapped by paper bands 16 is alterable between a rate that is faster than required by the net forming section, so that the wrapped wire form an increasingly large loop 26 between the wrapping at net forming stations, and a rate slower than that of net formation. When the loop of wire strikes lower limit switch 29 the slower rate is introduced until the loop straightens and the wire strikes upper limit switch 28. The drive train of the wrapping section includes a gear wheel 58 split into two halves along a diameter joining two gaps between teeth. Each half is fixed by screws 59 to one of a pair of semicircular plates 60, the plates being pivotable about rod 61 extending through holes 62. Each plate 60 has a pin 68, the pins being connected by a spring which urges the plates 60 together. When the plates 60 and half gear wheels 58 are together they form a circular wheel with 38 teeth. When limit switch 28 is actuated pneumatic piston and cylinder 73 moves sleeve 70 towards the split gear wheel, forcing wedge-shaped cam 72 into slots 74 and separating the two gear wheel halfs by sufficient to increase the circumference of the composite wheel by a length equal to one tooth, thereby increasing the rotation of shaft 21 and hence the speed of wrapping the wire by 2.63%. Divisional Specification 1427314 (see Division F2) claims the means for varying the rate of supply of flexible elongate material.
