Patent GB-614388-A (GB)
Title: Improvements relating to fractional distillation
IPC: B01D3/30
Filed: 1944-05-02
Abstract: Fractional distillation is carried out by establishing an unobstructed annular stream of the vapour mixture between a single rotating condensing surface and an enclosing evaporating surface, whereby condensate formed on the condensing surface is continually flung across the vapour stream and into contact with the evaporating surface.  By these means, high vapour velocities can be used without entrainment of condensate and without causing a large pressure gradient across the fractionator.  Figure 1 shows an embodiment suitable for operation at absolute pressures between 1 mm. and 40 mm. It comprises an electrically-heated casing 1 and a stationary tube 6, supplied with cooling fluid through conduits 7 <PICT:0614388/III/1> <PICT:0614388/III/2> and 61, upon which rotates, by means of magnetically driven armature 9, a sleeve 8 in the form of a series of truncated cones. The vapour to be fractionated is introduced at inlet 3, and bottom product is returned to the still through line 4.  The overhead product is withdrawn through outlet 5 which is connected to a final condenser and a vacuum pump.  Figure 3 shows an embodiment in which the electrically-heated evaporator 1 rotates as well as the condenser 8.  The liquid to be distilled is fed through electrically-heated pipe C1 into perforated, annular distributor C. The overhead vapours are condensed by upper cooling jacket 31, and the condensate is removed through outlet 5.  A non-condensible gas may be injected near the base of the fractionator to provide a carrier to take the vaporized material overhead.  The use of high vacua, i.e. pressures below 1 mm., is referred to.

Title: Improvements in and relating to electro medical apparatus
IPC: A61N1/40
Filed: 1934-03-16
Abstract: 435,547. Electromedical apparatus. CAESAR, V., 35, K÷nigstrasse, Stuttgart, Germany. March 16, 1934, No. 8360. Convention date, March 16, 1933. [Class 81 (ii)] In medical apparatus for treatment with electric oscillations means are provided for producing continuous irregular changes in the character of the oscillations ; in particular the magnitude of the current, the voltage, the frequency, the wave-form, and the periods of closure and breakage of the circuit may be subjected to variation. As shown the oscillating circuit comprises a push-pull valve rectifier 18, 19, supplied through a transformer 14 from mains 11 and supplying high tension current to a thermionic valve V the anode circuit of which includes a coil 101 and the grid circuit coils 82. The insulated patient may be connected by a lead 107 to a coil 105 on the core 100 of the coil 101, the other end of coil 105 being earthed ; alternatively treatment-circuit plates 110, 111, may be connected through block condensers 112, 113, across the coils 82, or the patient may be connected to one side of these coils with or without earthing of the other side. The lead 50 from the rectifier 18, 19, to valve V includes choke coils 52, 54, the coil 52 having across it smoothing condensers 60, 61, with a central point connected by a lead 62 with the return lead 64, 51, from the valve V. The character variations in the oscillations are obtained by rotary switches driven by rheostat or brake-controlled motors 37, 30, 67, 85, 95. The switch 36 periodically interrupts the current supply to the transformer 14, through leads 12, 13, the switch 24 effecting successive cutting in and then cutting out of parallel resistances 23 in the same supply. The switch 66 effects similar cutting in and cutting out of resistances 53 in the high-tension lead 50. Switches 84, 94, operate respectively to cut in and then cut out parallel condensers 81 and the parallel inductances 82, themselves in parallel in the grid circuit of the valve V. The wave-form is affected by surges produced by closing switch 36. The Specification as open to inspection under Sect. 91 describes an electrode for use with the above apparatus comprising a rubber or like sheath enclosing but spaced from a central conductor. The sheath may in use be coated with medicament such as a silver salt solution, and, when used in the urethra or uterus, may comprise an elongated tube closed at its free end, curved to fit the cavity treated, and carrying an obturator for the urethral or uterine orifice. This subjectmatter does not appear in the Specification as accepted.

Title: An improved process for tanning fish skins
IPC: C14C1/06
Filed: 1920-03-22
Abstract: 165,199. Knudsen, E. March 22,1920. Treating fish-skins; treatment preliminary to tanning; chrome tanning.-A process for tanning fish-skins, such as the skins of catfish, skate, &c., consists in salting the skins; liming in a. dilute solution, preferably softened with soda, the strength being progressively increased by additions of milk of lime; rinsing and, with or without puering, submitting to the action of a vegetable or chemical tanning agent which is only slightly acid or is neutralized. For chrome tanning, the skins are puered with weak chicken manure, then treated in a solution of sodium chloride to which hydrochloric acid is added gradually in increasing quantities. After soaking in soft water, the skins are then tanned in pure chromate in gradually increasing quantities, with or without the addition of hydrochloric acid. They are then washed in soft water and protected from the action of light, being subsequently treated with sodium thiosulphate, or with soda, and finally freed from acid by means of tepid water and chalk.

Abstract: 952,644. Building motions. TWEEDALES & SMALLEY Ltd. March 9, 1962 [March 9, 1961], No.8716/61. Heading DID. A builder motion for a ring frame or like textile machine in which a drive shaft 18 is coupled, e.g. by a drum 17, a flexable connection 15, a bar 14, a flexible connection 12 and a pulley 13, to drive a traverse rail 11, resilient means e.g. a coil spring is coupled to the drive shaft 18, e.g. via the drum 17 and a flexible connection 22, so that it becomes loaded when the shaft 18 is driven in a direction to lower the traverse rail and assists in driving the shaft when the latter is rotating to lift the traverse rail. Sets of elements 13,12,15,16, 17,18,19, 20, 22 are arranged at intervals along the length of the machine and associate with the common draw-bar 14. In the coupling between the shaft 18 and each associated spring it is preferable to arrange that connection 22 is divided and that the motion is transmitted via joined, but eccentrically, arranged drums such that the effective force applied by each spring to the shaft 18 remains approximately constant irrespective of the position of the traverse rail.

Abstract: 1,028,787. Gun mounts. BREVETS AEROMECANIQUES S.A. March 1, 1965 [March 12, 1964], No. 8719/65. Heading F3C. [Also in Division F2] A gun mount comprises two aiming control members 4 1 , 4 2  for aiming the gun about vertical and horizontal axes and which carry levers 5 to enable the gunner to fix the gun A in position with respect to the corresponding aiming axis and at least one control element 18 for controlling the firing of the gun. The gun is adjusted for elevation by member 4, through shaft 10 fast therewith, gear 41, Fig, 1 (not shown), and toothed rack 42 and is adjusted for direction by member 4 2  through a similar shaft 10, gearing 43, 44, 45, 46, 47 on stirrup 3, and teeth 48 on the actual support 1. The members 4 1 , 4 2  are fixed in adjusted position by similar locking devices actuated by pivoted movement of levers 5, which movement through gearing 6, 7, 8 causes sleeve 9 to rotate so that a hub 12 is caused to move axially by the engagement of oblique abutting surfaces on the members 9, 12 to grip the flange 14 fast with the member 4 1  between friction surfaces 16, 17. Pivoted movement of member 18 causes a rod 19 to move axially between two positions for initiating and stopping firing of the gun, a bevelled guide 25 on the member 18 moving a rod 23 axially to actuate linkage 22 which in turn moves rod 19 axially. A similar arrangement may be provided on the lever 5 of the member 4 2  to choose the kind of firing.
