Title: Vacuum centrifuge
IPC: B04B9/12
Filed: 1965-06-09
Abstract: 1,108,694. Centrifugal separators. M. CHRIST. 9 June, 1965 [10 June, 1964], No. 19394/65. Heading B2P. [Also in Division F2]  The shaft 7 of a centrifuge rotor which rotates in an evacuated chamber 1 is sealed where it passes through the chamber wall by means of an oil-lubricated gland 9 to which oil is supplied from a tank 11 via pipe 10, oil leaking from the gland being automatically returned to the tank 11: The centrifuge may be of the ultracentrifuge type having a rotor speed of 60,000 r.p.m. The chamber 1 is closed by a removable cover 2 and is evacuated through a pipe 4 by means of a vacuum pump 5. During centrifugation oil leaking from the gland enters a chamber 12 and flows by gravity through a pipe 13 into a tank 14 which is connected by a pipe 15 to a tank 16 itself adapted to be connected via a pipe 17 to the tank 11 upon operation of an electromagnetically operated valve 18 which during centrifugation is normally closed. During centrifugation the chamber 12 and the interior of the tanks 14, 16 are under vacuum. When the vacuum pump 5 is shut upon termination of centrifugation an electromagnetically operated valve 19 opens to admit air in the chamber 1. The air forces the leakage oil which has accumulated in the tank 14 into the tank 16. After a slight delay, the valve 18 in the line 17 opens for the oil to flow from the tank 16 back into the tank 11. The delayed opening of the valve 18 may be achieved by means of a time-lag relay, Fig. 2 (not shown) incorporated in a circuit comprising the valves 18, 19, and their associated electromagnets. Alternatively, the switch 22 operating the electromagnet associated with the valve 18, Fig. 3, is connected in series with a battery B and a switch S which is supported on a bracket 23 fixed to the wall of the chamber 1 and is normally held open during centrifugation. A manuallyoperated switch 28 in series with the battery B and with the switch S is closed during centrifugation but is adapted to be opened when centrifugation stops to prevent the battery from running down when the cover 2 is removed. The switch 28 is opened only when after centrifugation. a certain time has elapsed after the opening of the cover 2, during which time the switch 22 will have caused the valve 18 to open so as to transfer the leakage oil from tank 16 to tank 11. In a modification. the centrifuge drive unit is disposed above the chamber 1 and the drive shaft is provided with a centrifuging plate which conveys leakage oil to a chamber similar to chamber 12 and thence to a tank corresponding to tank 14.

Title: Improvements in thermionic valve circuits
IPC: H04B15/00
Filed: 1927-07-21
Abstract: 299,089. Gramophone Co., Ltd., and Mittell, 33. E. G. July 21, 1927. Thermionic amplifiers.-In a thermionic valve circuit comprising a plurality of valves in cascade, the filaments of which are heated from an alternating or fluctuating current source, a valve V1 produces, on account of the fluctuation of its filament potential, a hum which is amplified by subsequent stages and one or more subsequent valves V2 are arranged to produce a hum of initially greater amplitude and of such phase that it substantially neutralizes in the output circuit T2 the hum produced by the first valve. For this purpose one of the valves has an impedance f in its filament circuit and a connection between its grid or anode circuit and a point in the impedance. As shown, the impedance consists' of a potentiometer across the filament circuit of the valve V2 and the grid and anode circuits are connected to the variable tapping. According to a modification a resistance is arranged in series between each filament terminal of the valve V2 and the secondary of the heating transformer, and the filament is connected to adjustable contacts on the resistance so mechanically coupled that the total resistance of the filament circuit remains constant while the average difference of potential between the grid and filament of the valve can be adjusted (Fig. 2, not shown).

Operating doors by springs; checks.-Relates to door-operating devices of the type comprising a dash-pot and a resilient closing-medium disposed on opposite sides of a spindle connected to the door, and in which the resilient medium acts in a rectilinear direction transverse to the spindle. According to the invention, a common sliding member transmits motion from the spindle to the two actuated parts, and other features include provision for interchanging the resilient medium without deranging the spindle-actuated part with which it co-operates, a self-contained and readily detachable dash-pot, a crank-motion which provides for right and left hand operation and also for holding the door open, alternative rack-andpinion gear, and a special formation of the arm connexions between the spindle and the door. The body containing the mechanism comprises a centre part a, Fig. 1, for attachment to the door, and lateral tubular members b, c secured to the centre part a by faced flanges and screw pins. The member b contains two springs d, Figs. 1 and 2, connected as a self-contained unit by plates d<2>, d<4> with sliding connexions d<5>, d<6>. One plate d<4> abuts against a sliding frame g guided in slots a<4> in the centre part a by rollers g<2>. A slot g<1> in the frame g is engaged by a roller f<3> on a crankdisk f<1> on the main spindle f. The dash-pot member c is closed by a gland c<2> through which the piston-rod k projects for connexion with the frame g. The piston k<2> is provided with a ball valve k<3>. The liquid returns through an aperture k<4> regulated by a screw k<5>, a groove k<6> permitting freer escape of the liquid when the piston is near the end of the outward stroke. The main spindle f is mounted in ball bearings e<1>, e<2> on a sleeve e in the centre part a. The crank-motion automatically provides for right and left hand operation. The dead-centre position of the crank allows the door to remain open; this stationary position may be made more certain by providing a recess in the side of the slot g<1> to receive the roller f<3>. The crank may be replaced by a pinion engaging a toothed rack on one side of the frame g, in which case the change from right to left handed can be effected by providing racks on both sides of the slot, and mounting the sleeve e so that it has an eccentric adjustment for engaging the pinion with either rack. The arm connexions between the spindle and the door are made mainly of sheet metal. The main arm consists of two plates m, m<1>, Fig. 1, having a lug m<2> at one end for attachment to the spindle f. Near the other end, the plates m, m' are riveted together at m<3>, leaving the ends free to be sprung over a pivot pin r, over which are also sprung the free ends of a fork p, Figs. 1 and 5, adjustable on a screw pin r<3> secured to the door by a universal joint r<4>.

Title: Improvements in or relating to processes for producing on woven materials pattern effects combined with permanent mechanical effects
IPC: D06Q1/02
Filed: 1952-08-01
Abstract: Pattern-weave effects and a mechanical finish are obtained in fabrics comprising nitrated and ordinary natural or regenerated cellulose yarns by printing the fabric locally with a synthetic resin precondensate, subjecting it to a mechanical treatment, curing the resin and then treating the fabric with an alkaline solution and, if required, heat or steam, whereby the nitrated yarns in the un-printed areas are removed.  The mechanical treatment may comprise calendering or embossing.  Instead of printing the resin locally, the fabric may be impregnated all over with the resin and an alkaline reserve printed on the fabic to prevent curing of the resin at selected parts.  The resin may be a condensate of formaldehyde with urea, thiourea, ethylene urea, acetylene diurein or its derivatives, dicyandiamide, melamine, phenol, phenol derivatives or mixtures of these components and a catalyst may be included in the resin composition which may also include acid dyes, vat dyes, free leuco compounds, sulphuric acid esters of leuco dyes and metal powders to give gold, silver or copper effects.  After curing the resin the fabric may be impregnated with a caustic soda solution or printed with a caustic soda solution thickened with British gum or wheat flour followed by heating or steaming, after which the fabric is washed and may be dried under tension.  Prior to the process the fabric may be singed, desized, boiled in a solution containing Yarmor Pine Oil and bleached, and after the process the treated fabric may be dyed, the resin-coated areas remaining undyed, transparentized with sulphuric acid and after-mercerized, or impregnated with methyl, ethyl or glycol cellulose, cellulose sodium zincate or viscose and subsequently mercerized, or shrunk with an alkali solution of mercerizing strength.

Title: Improvements in or connected with Ordnance.
IPC: F41A25/02
Filed: 1918-11-29
Abstract: 130,576. Soc. Anon. des Etablissements Delaunay-Belleville. July 31, 1918, [Convention date]. Recoil apparatus. - Relates to differential recoil guns, i.e. guns which are fired during run-out, the momentum of the gun during run-out opposing the recoil. The invention consists in holding the gun in the recoil position by a catch released by percussion-gear previously cocked by the recoil, the release of the barrel being also governed by a second catch liberated by the closing of the breech. A special brake is also provided to retard the engagement of the barrel with its retaining catch. Fig. 1 shows the barrel held in its recoil position by a pivoted catch 4 which is disengaged, to release the barrel for run-out, by a spring-controlled percussion plunger 6. This plunger is cocked into engagement with a sear 8 by the contact, during recoil, of a lug 9 on the barrel with a pawl 10 spring mounted in a casing 11 on the plunger. As soon as the plunger is held by the sear, the pawl 10 is depressed, into the position shown, by the contact of the casing 11 with a lever 13. forked to engage pins 14 on the pawl. Fig. 5 shows the plunger 6 also retained by a second catch 8' released by the depression of a pin 22 when the breech is closed. The release of the barrel may therefore be automatic if the trigger 8<a> is kept pulled. The engagement of the barrel with the catch 4 is retarded bv a brake 20 shown in Fig. 4. The end 18 of the piston-rod of this brake is engaged at the end of recoil by a spring catch 17 mounted on the barrel. As the barrel runs out to meet the catch 4, the piston 20 is drawn forwards to brake the movement, the barrel becoming disengaged from the brake when the catch 17 is raised by a fixed incline 21.
