Title: Method of treating lesions
IPC: A61K38/00
Filed: 1965-03-11
Abstract: A method of treating a lesion in a non-human mammal comprises applying thereto a material which is a cellular foetal adjunct of the birth or parturition of said mammal or is derived from such an adjunct, the foetal adjunct having been treated by deep freezing or lyophilisation to resist deterioration on storage, having been stored and having been reactivated after storage and prior to application. Typical cellular foetal adjuncts specified include the amnion, amniotic fluid surrounding the foetus, the yolk-sac associated with the foetus, and the allantois, umbilical, chorionic and placental tissues, and placental blood. The cellular foetal adjunct is preferably applied as a tissue graft directly to the lesion.  In a modification, a tissue derived from a non-human mammal other than the mammal to be treated is applied as a graft over the graft of foetal adjunct tissue.  The therapeutic material derived from the cellular foetal adjunct may be derived by implanting the foetal adjunct in a non-human mammal other than the mammal to be treated and either of the same or a different species, and recovering secondary cells, e.g. lymphatic fluids, or blood, therefrom.

Title: Induction heating apparatus using a saturable reactor for power control purposes
IPC: H02M7/48
Filed: 1976-03-16
Abstract: 1491415 [Control systems for inductively heated cooking apparatus MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 16 March 1976 [19 March 1975] 10454/76 Heading H2H [Also in Division H1] An induction heating apparatus, such as a cooker, has the heat output of the heating coil controlled by a D.C. biased saturable reactor. A heating coil 44 of an induction cooker is supplied from an A.C. source 14 by way of a full-wave rectifier 10 and a frequency converter which includes oppositely connected thyristor 30 and diode 32. The high frequency current energizing the coil 44 is controlled by a saturable reactor 42 by varying the D.C. bias fed to the control winding a, b. Gating pulses for the thyristor 30 are developed by a gating circuit 34 which is controlled by a zero crossing detector 50, a delay circuit 52 and a D-type flip-flop pulse generator 53, the supply voltage for these circuits on line 28 being controlled by a voltage regulating circuit 20. The input and energizing currents are measured by current transformers 301, 302 respectively, the outputs of which are fed by way of diodes 303, 304 to input terminals of operational amplifiers 305, 306, 307. The output of a voltage regulator 311 is connected to an input of amplifier 305 by way of a voltage setting circuit 308, the output of the amplifier 305 being connected to the control winding a, b of the saturable reactor 42 thereby to control the heating of the coil 44. In parallel with the control winding is connected a delay circuit 312, the purpose of which is to prevent a large initial energizing current flowing in the heating coil 44. Voltage divider 310 and amplifier 307 and voltage divider 309 and amplifier 306 both connected to the gating circuit 34 respectively prevent high and low levels of energization of the heating coil 44. In a modification the energizing current is measured by a current transformer having two secondary windings.

Title: Improvements in or relating to alternating current signal receiving circuits
IPC: H04Q1/446
Filed: 1946-04-04
Abstract: 613,951. Voice frequency signalling. STANDARD TELEPHONES & CABLES, Ltd. (Standard Telephon und Radio Akt.-Ges.). April 4, 1946, No. 10481. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 4, 1946.] [Class 40 (iv)] A circuit responsive to signals of a predetermined frequency is made unresponsive to one or more predetermined subharmonics of that frequency. Incoming signals received over transformer T1 are amplified in valves V1, V2 and passed through transformer T3 to parallel tuned circuits, the first of which C4, L2 is tuned to the signal frequency and passes the accepted frequency through a rectifier W1 to operate signal relay R1. The other two tuned circuits C5, L3 and C6, L4 are tuned to one half and one third of the signal frequency respectively and, if either of these components is present it is rectified in bridge W2 or W3 and, by operating relay R2, breaks the operating circuit of relay R1. In an alternative arrangement the sub-harmonic frequencies energize an opposing winding on the signal relay. In another arrangement, Fig. 3 (not shown), the output level of the signal voltage is made adjustable by means of a rectifier having an adjustable polarising voltage connected across the transformer T3. In this arrangement also the blocking relay has a second winding which is energized when the signal transmitting relay of the station is operated. This prevents the local signalreceiving relays responding accidentally to signal currents transmitted by the associated equipment. Specification 607,227 is referred to.

Patent GB-106668-A (GB)
IPC: A43D69/04
Abstract: 106,668. Briggs, T., and British United Shoe Machinery Co. May 31, 1916. Slugging.-Relates to machines for inserting a number of rows of slugs or other fasteners in the manufacture of boots and shoes, and particularly to a three-row slugging-machine for inserting three rows of slugs down the centre and a double row of slugs round the edge of half-soles used in repairing heavy boots, such as army boots, and consists in an arrangement for varying the position of the slugs both in, and laterally of, the line of feed; this affords means of arranging the groups of slugs down the centre of the sole so that they run across the sole approximately parallel to the waist-line, whether for rights or lefts. The invention is described as applied to a machine having generally the construction of the machine described in Specification 16303/91, and the operations of wire-feeding, shearing, and driving are carried out in the usual manner. Separate stationary shear-pieces 1, 2, 3, movable throatpieces 4, 5, 6, and driver supports 7, 8, 9 are provided for each row of slugs, those of the outside rows being adjustable with respect to the centre row. The outside shear-pieces 1, 3 are adapted to slide on a bracket 10 and to be clamped by bolts 12, 11, while the outside throat-pieces 4, 6 are carried by members 32, 33 adapted to be simultaneously adjusted on a bracket 13 by a right and left screw 16, and then to be clamped by bolts 15, 14. The outside driver supports 7, 9 are similarly and simultaneously adjustable in a slide 19 by means of a right and left screw 20. The awl bar 23 is extended horizontally and forwardly at its lower end to support a single awl 24, which is used in line with the centre driver 25. To vary the line of slope of the fasteners with respect to the line of feed, the driver supports 9, 7 are provided, on either side of an horizontal line through the driver 25 and perpendicular to the line of feed, with recesses 26, 27 and 28, 29 to receive the drivers 30, 31; the outside throat-pieces 4, 6 may be correspondingly advanced or retracted by sliding them in their members 32, 33 and afterwards clamping them by bolts 34, 35, while the outside shearpieces 1, 3, instead of being adjustable in the line of feed, are provided with separate wire-receiving orifices 36, 37 and 38, 39. The wire-feeding mechanism is substantially similar to that described in the above-mentioned Specification; the driver roll, however, is made of sufficient width to span the three wire supplies, and an independent co-operating roll is provided for each wire. These co-operating rolls are each provided with means for relieving their pressure on the wire, to allow the machine to be used as a one or two row slugger, while the outer rolls are mounted for adjustment on their supporting-bracket in a manner similar to the throat-pieces 4, 6.

Filed: 1970-03-06
Abstract: 1,244,577. Centrifugal separators. VOGELBUSCH G.m.b.H. 6 March, 1970 [14 March, 1969], No. 10816/70. Heading B2P. [Also in Division C6] A two-stage centrifugal separator for separating the gas and liquid fractions of a foam comprises two groups of rotatable annular plates 4, 5, Fig. 1, each defining at least one gap 6, 7 and inclined relative to a plane normal to the axis of rotation of the plates, an inlet socket 10 for introducing foam to be separated into the or each gap 6 of one separator stage in the region of the axis of rotation of its plates 4, a fluid receiver 11 at the periphery of the rotatable plates 4, 5, and a gas receiver 13 for receiving gas from the or each gap 7 of the other separator stage adjacent the axis of rotation of its rotatable plates 5, the width a of each gap 6, 7 being no greater than one-tenth of its length b. As shown the foam is introduced through the inlet socket 10 and apertures 8 in the plates 4 and passes through the gaps 6 between the plates 4 where due to centrifugal force it becomes separated into liquid and gas fractions which are centrifugally delivered to the fluid receiver 11 which may be constructed as a volute casing. The liquid fraction is discharged through socket 12 which is tangential to the receiver 11. The gas fraction, at least partially freed from liquid is delivered from the receiver 11 centripetally through the gaps 7 between the plates 5 of the second separator stage and passes via apertures 9 in the plates 5 into the gas receiver 13 from which it is discharged through a socket 14. Any liquid still present in the gas fraction is thrown by centrifugal force from the gaps 7 back into the receiver 11. The plates 4, 5 are secured at their periphery by means of bolts 17 and spacers 18 to a dished support 3 mounted on a shaft driven by a motor 2. In Fig. 2, the centrifugal separator 4, 5 is mounted in a closed vessel 24 which is under vacuum. Foam is supplied through a duct 25. The separated liquid is discharged from the annular chamber 11 via a pipeline 26 and a volumetric rotary piston pump 29 to a valved line 29. The gas is withdrawn from the receiver 13 via a line 31 by means of a vacuum pump 32 and is delivered into a discharge line 33. Liquid separated in the vessel 24 before it passes through the centrifugal separator is discharged via a pipe 36 which is connected to the pipeline 26. Alternatively, the separated liquid may pass from the chamber 11 via a pipe 38 into the bottom of the vessel 34 in which case the pipeline 26 is dispensed with. One or more separators may be mounted externally of a yeast growing fermentation vat (see Division C6) and connected via one or more troughs to an upper zone of the vat interior where foam accumulates above the liquid.
