Title: Process and apparatus for the production of alcohol form sugar beets and other sugar-containing raw materials
IPC: C12P7/06
Filed: 1934-06-06
Abstract: 432,387. Centrifugal machines. AKTIEBOLAGET SEPARATOR, 8, Fleming- gatan, Stockholm, and SVENSJO, N. E., 30, Stugvagen, Nockeby, both in Sweden. June 6, 1934, No. 16823. [Class 23] [See also Group VI] In processes for producing alcohol from sugar containing liquids produced by extraction from sugar beets or other sugar containing vegetables, the yeast after fermentation in vats is extracted by means of centrifuges having a conveying device or pile of discs arranged within the bowl and a sludge space outside the conveying device or pile of discs, the separated yeast being discharged to a point 1 immediately outside the conveying device or pile of discs, or, when the outer periphery of the conveying device or pile of discs is at a smaller distance from the centre than seventenths of the inner radius of the bowl, to a point at least seven-tenths of this radius from the centre. In the type of centrifuge employed, the inlet opening or openings 4 of the discharge channels 5 is or are arranged at a level corresponding to substantially half of the height of the pile of discs 2, the inlet openings of the discharge being located at the greatest diameter of the sludge space. The shape of the bowl walls is preferably such that they slope towards the outlet openings 4 in order that the outseparated matter may slide easily along the bowl wall towards these openings.

Title: Improvements in or relating to method of growing crystals
IPC: C30B7/00
Filed: 1947-06-26
Abstract: Crystals are grown in two stages: in the first stage seed bodies cut from crystals of the material-to-be-crystallized are planted in a solution of the material and the solution is caused to flow relative to the seed bodies while the temperature is progressively lowered; all the seed crystals thereby grown are removed from the solution and inspected, and only the sound crystals are replanted in solution for the second stage of growth. In the growth of ammonium dihydrogen phosphate and its isomorphs, the yield of sound full-size crystals obtained by this two-stage process is greater than in prior one-stage processes.  In an example, seed plates 5 (Fig. 3) cut from crystals of ammonium phosphate with the larger sides <PICT:0653737/III/1> <PICT:0653737/III/2> <PICT:0653737/III/3> <PICT:0653737/III/4> 1.5 inches long, are mounted in a tray 7 (Fig. 5), which is rocked back and forth on a fixed axis, as indicated by the double-arrow, in a chamber (not shown) through which warm air is circulated. An aqueous solution (saturated at 36 DEG  C.) of ammonium phosphate at a temperature of 38 DEG  C. is introduced into the preheated tray; and the temperature of the circulating air is then gradually lowered to normal room temperature during about 8 days.  The crystals thereby grown are removed from the tray, and those which have a clear pyramidal shell 11 (Fig. 4) on one or both ends are replanted with suitable spacing (Fig. 6) for growth into full-size crystals.  In this second stage the initial temperature of the solution is about 41 DEG  C., and the growing-time is about 45 days. The two-stage process of crystallizing makes possible the use of addition substances in the first stage, which would be deleterious to the product in a one-stage process.  Specification 653,736 is referred to.
Patent GB-1311195-A (GB)
Title: Circuit arrangement for igniting and supplying gas and or vapour discharge lamps
IPC: H05B41/46
Filed: 1970-04-09
Abstract: 1311195 Supply circuits for discharge lamps; standby supply systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 9 April 1970 [12 April 1969] 16895/70 Heading H2H A discharge lamp 4 is supplied by a circuit the terminals 1, 2 of which are connected to the A.C. mains whilst terminals 7, 8 are connected to an auxiliary source 9 so that an ignition voltage which is higher than the cold ignition voltage of the lamp is supplied and the auxiliary source maintains a potential across the lamp electrodes when the mains fails. Initially, on closing contacts 6, 10 the A.C. mains voltage is insufficient to start the lamp so that no current flows through a relay coil 5 thus ensuring that its contact 11 is closed. The D.C. source 9 is therefore connected to an inverter 13 via contacts 10, 11 and a normally closed contact 12, the high frequency output of the inverter being at a sufficiently high voltage to start the cold lamp, thus causing a current to flow through the coil 5 thereby opening the contact 11. The source 9 is therefore disconnected from the inverter. If the mains voltage fails for a few cycles the contact 11 is closed and the inverter maintains the ionization in the lamp so that the circuit attempts to re-start the lamp when the mains supply returns. At the end of a predetermined time following the mains failure, for example fifteen seconds, a time switch 18 opens the contact 12 and closes a contact 22 so that a motor 21 which rotates a cam disc 20 is energized. A projection on the cam disc intermittently closes a contact 19 to connect the D.C. source to the inverter via the closed contacts 10, 11. The inverter therefore makes periodic attempts to ignite the lamp and succeeds when the lamp has cooled sufficiently. The D.C. source is then disconnected from the inverter by the coil 5 opening the contact 11. Instead of being used, as described above, to reignite the lamp on return of the mains supply after a failure the D.C. source may be used as a standby supply.

IPC: H04N3/14
Filed: 1966-04-19
Abstract: 1,148,811. Colour television. E. H. MILLER, and L. P. MIRANDO. 19 April, 1966, No. 17039/66. Heading H4F. [Also in Divisions C4 and H1]  A scanning device for a colour or black and white display or camera tube, comprises parallel layers including layer 24 containing spaced first conductors, layer 28 of electric light transducer material (electroluminescent ZnS or photoconductive CdS) and layer 26 containing spaced second conductors. A substantial number of the first conductors overlap in angular relationship (e.g. orthogonal or polar configurations) a number of said second conductors to provide a scanning area, each of said first and second conductors containing a gap 54 adjacent to one of which in each row is a trigger gap. An impervious envelope enclosing the gaps contains an ionizable medium such as an inert gas. A D.C. potential across the gaps 54 is of a value slightly less than that required to create a discharge in same except upon initiation by a discharge in an adjacent gap. Potentials are periodically applied for creating triggering discharges at the triggering gaps and permanent magnets, e.g. 82, 84, 88, and 90, A.C. or pulsed D.C. electromagnets extend along the line of gaps to cause the discharge in each triggering gap to move transversely and sequentially from gap to gap. The Fig. 1 display device comprises opaque layer 40 of minute conductive elements each surrounded by insulating material, photoconductive layer 36 and electroluminescent layer 38 whose intensity varies as the modulated H.F. signal applied to conductive layers 32 and 34. For colour, layer 34 comprises series of two or three parallel strips with corresponding different coloured electroluminescent strips in layer 38, or only layer 34 may be sub-divided, the strips being of different coloured filters. Interlaced pictures are similarly obtained. In a T.V. camera, layer 38 is photo-conductive, while for colour, layer 34 is a series of two (e.g. as for the Land system) on three different coloured filter strips, photo-conductive layer 38 is similarly divided and may be further segmented as a checkerboard to eliminate opaque layer 40. In the display device of Fig. 5 (not shown), an electroluminescent layer between crossed array conductors is zero potential scanned and a modulated H.F. signal applied to the same layer, substitution of same by a photo-conductive layer providing a camera (non-zero potential scanned); two, three or more colour systems and interlaced pictures may be achieved as above.

Filed: 1917-11-21
Abstract: 154,632. Carey, R. F. Nov. 21, 1917. Crank-actuated pumps; stroke, varying; revolving-cylinder pumps. -Apparatus for the hydraulic transmission of power, comprising a variable-capacity pump supplying one or more hydraulic machines, is provided with hand or ordinary means for adjusting the pump capacity, and in addition with means actuated by the pressure in the system, when it exceeds a predetermined value, to limit the delivery at which the hand control can set the pump, the pressure-actuated means comprising a piston or equivalent variably loaded by compressed air or gas, springs, weights, &c. In the form illustrated in Fig. 1, the pressure acts on a piston 1 connected to a larger piston 4 acted on by compressed air contained in a cylinder 5, and the pump control rod 13 is linked to a lever 10 connected to the piston 1 and to a hand lever 15. The cylinder 5 is provided with a hole 19 so disposed that the desired initial air pressure is obtained when the cylinder is screwed home against the shoulder 7. If desired, the cylinder 5 may be filled with liquid and provided with an open pipe 11<a>. In other forms, the piston 1 is moved against the action of springs to operate the lever 10, to move its fulcrum or to adjust the position of the stops between which the hand lever 15 works. In a further modification, the pump control rod 30, Fig. 7, is provided with washers 37 and a spring 20 disposed in a cylinder 38 slidable in the pump casing, the cylinder cap being connected to the lever 10, which is linked to the pump casing and to the control 15. In this case, the spring 20 yields to allow the track 36 to move towards its central position on the attainment of predetermined pressure.

Title: Improvements in and relating to an hydraulic control device for a gear box
IPC: F16H63/30
Filed: 1959-05-21
Abstract: 858,341. Change-speed control. COMPAGNIE DE PONT-A-MOUSSON. May 21, 1959 [May 23, 1958], No. 17277/59. Class 80 (2). [Also in Group XXXIV] An hydraulic change-speed control for a change-speed gear of the type having constantlymeshing gear elements with ratio establishing brakes and/or a clutch is shown as actuating the band brake 3, Fig. 1, of a planetary gear reaction element 1, the brake normally being applied when oil under pressure from an engine or other driven pump P 1  is admitted through a manually controlled ratio selecting valve Sand a pipe 11 to a servomotor V, the piston of which is then moved against spring bias so that a spigot 6 thereon tightens the brake band to establish the ratio, the brake alternatively being engaged, if the pump P 1  is for any reason inoperative, by depression of a pedal 21 connected to a master cylinder P 2  fed from a header tank 18 and supplying oil under pressure through a pipe 14 to a secondary servomotor W. In the form shown in Fig. 1, the secondary servomotor W comprises a small inner piston 13 contained within a cylindrical flange 12 fast with a cover 9 for the main servomotor V, admission of oil under pressure through the pipe 14 forcing the small piston 13 upwards to engage the inner surface of the main servomotor piston for brake engagement. In a modification, the main servomotor V, Fig. 3, lies beside the secondary servomotor Wa, and the single brake band is replaced by two parallel brake bands 3, 3a. Alternatively, the two servomotors V, Wa of Fig. 3 may act upon a single brake band 3 of sufficient width to coact with the actuating spigots on the servomotor pistons. In a further modification the normally used servomotor V, Fig. 4, engages one end of the brake band 3, and the secondary servomotor Wb, energized from the master cylinder P 2 , lies on the opposite side of the band. Since the reaction element 1 of the planetary gear rotates in the direction shown by the arrow f, the secondary servomotor Wb is made of larger size to provide the additional force required to maintain the brake band 3 in the engaged position.

Title: Improvements in the manufacture of metal tubing
IPC: B21C37/12
Filed: 1929-06-06
Abstract: 333,674. Beaumont, J. H., (Titeflex Metal Hose Co.). June 6, 1929. Tubes.-Flexible helical metal tubes with a locked seam and an intermediate groove are made by rotating a mandrel in a stationary die, consisting of a former part and a number of similar helical portions acting as a stripper. The die is formed of replaceable parts consisting of an end plate 20, a series of stripping plates 21, a forming plate 22, a backing plate 23 and a bush, all secued by screws 67 in a casing 4, which is held by a screw in a holder 2. The inner stripping plate may be pinned to the forming plate. The stripping plates and forming plate and the adjacent sides of the end plate and backing plate are formed with helical faces which match each other and are provided on their near face with internal radial fins for guiding the formed tube. The bush which is secured by a screw 64 in the backing plate has a helical end 53 cooperating with a similar recess 55 in the plate 22, the backing plate being cut away at 52 so as not to interfere with the action of the surface 53. A mandrel 17, preferably reversely tapered, and carried by a rotating hollow spindle 5, draws the strip through sectioning dies and causes the inner edge to be flanged between the surfaces 53, 55 and the strip to be bent round the mandrel by a removable flanged roll 31. The flanged edge engages the hooked edge of the next convolution, the flange on the roll 31 ensuring that the flanged Edge of the strip interlocks with the hooked edge. The seam is closed by a second removable roll 32 co-operating with a helically arranged finger piece 26 secured by a screw 50 to the backing plate and bearing on the mandrel. The finger piece is thicker at its free end so as to lock the seam. The rolls are mounted between the stripping plates and the forming plate, the roll 32 being carried on a spindle which is radially adjustable by a screw. The seam may be finished by grooved wheels 12, 13 rotated by gearing 7, 8, 9 from the spindle 5 and co-operating with a stationary threaded member 70, which is screwed on a rod 71 passing through the mandrel and secured in a clamp 73. This member also assists in traversing the formed tube. U.S.A. Specification 1,492.067 is referred to.

Abstract: 957,242. Insulating electric conductors. LICENTIA PATENT - VERWALTUNGSG.m.b.H. May 7, 1962, No. 17496/62. Heading H1A. A method of insulating electrical conductors, for example the windings of dynamo-electric machines, comprises coating at least part of the conductors with material consisting of or containing mica and wrapping with shrinkable material in sheet or strip form, and then carrying out the shrinking step. The shrinkable material consists of a thermo-plastic carrier tape and is coated on one side with silicone rubber to allow removal of the material after heating to effect the shrinking. The wrapping serves to prevent seepage of the binder from the mica insulation in a die-pressing operation and also rounds the angles of the insulation in shaped coils. Several layers of shrinkage material may be applied to certain ports to grade the shrinkage force. If the operating temperature is comparatively low the shrinkage material need not be removed.
