Title: Improvements in or relating to feeding dough pieces to pans or tins for breadmaking
Inventor: SARGINSON HARRY
IPC: A21C9/08
Filed: 1957-02-13
Abstract: 825,161. Panning dough. BAKER PERKINS Ltd. Feb. 12, 1958 [Feb. 13, 1957], No. 4885/57. Class 87(2). In a dough piece panning machine of the type in which dough pieces are conveyed to a discharge point and dropped into tins through a trough having displaceable walls or flaps the timing of the opening of which is governed by the arrival of the dough pieces at the discharge point, the means for causing the trough to open and deliver the dough pieces to the tins are located at, or associated with, the trough itself and are only actuated by a dough piece when received in the trough. The dough pieces 2 drop from the end of the conveyer 1 into.a trough 5 of which the sides 7, 8 may be pivoted to move, by the operation of a cylinder. and-piston device 9 through a bell-crank 10 and linkage 11, 12, to open the trough and drop dough pieces into a tin 6 below. A light beam is directed along the bottom of the trough 5 to a photo-electric cell 23 which. when the beam is interrupted by a dough piece, operates a relay (not shown) which causes a valve 13 to actuate the cylinder-and-piston device 9. Alternatively a pressure plate may be hinged inside one of the trough walls so that, when depressed by the weight of a dough piece, it actuates a valve trip lever, so operating the cylinder-and-piston device. In a third alternative the arrangement shown in Fig. 2 may be used, in which the trough wall 8a is connected to a shaft to which is secured a plate 25 on which are two posts 26, 27 and an arm 28 carrying a set-screw 29. The trough wall 8a is normally held in closed position by an adjustable spring 39 and when a dough piece falls in the trough the wall 8a is tilted until the post 26 strikes the side of a lever 35 linked to a bell crank 10a, so limiting the initial displacement of the wall, the setscrew 29 at the same time moving a valve trip lever 30 and operating a pilot valve 31 which moves with the lever 35. The cylinder-andpiston device 9a then actuates the bell-crank 10a, so tilting downwards the walls 7a, 8a through rods 32, 34 and levers 33, 35, the latter coming out of engagement with the post 26 and into engagement with the other post 27, where the trough is in the fully open position. The tins 6 are conveyed in succession on a continuously moving conveyer 3, each being held below the trough by a stop 15, operated from the bell-crank 10 through a parallel-linkmounted platform 18 on the surface of which rests a roller 19 on the end of a lever 20 carrying the stop 15, the platform 18 allowing for the interposition of lost motion to impose delay between opening the trough and releasing the tin to allow time for the dough piece to enter the tin. A separate cylinder-and-piston device may be used to actuate the stop for the tins.

Patent GB-636126-A (GB)
Title: Improvements in and relating to aerial systems for radio navigational aids
IPC: G01S1/02
Filed: 1947-02-21
Abstract: 636,126. Aerials. CULLEN, A. L. Feb. 21, 1947, No. 5201. [Class 40 (vii)] An aerial system comprises an energized primary loop P producing a uniform radiation field and two parasitic secondary loops S1 and S2 disposed in an adjacent parallel plane and arranged to overlap the primary loop so that by inductive coupling the induced currents in the two secondary loops are in antiphase and in quadrature with that in the primary. The resultant combined radiation pattern varies as 1+m sin #, where m may be given any value by choice of the offsets d1 and d2. The loops S1 and S2 which are connected in parallel and tuned to resonance by condenser C are centred at the ends of a diameter of the primary loop and embrace points of current maxima. One loop is offset inwards and the other outwards, whereby their. mutual couplings are of opposite sign and result in induced currents in antiphase. A practical embodiment of the system for use as an omnidirectional beacon is disclosed in Figs. 6, 7 and 8 (not shown) and comprises a horizontal array mounted on a vertical shaft for rotation in azimuth. Energy is fed to the primary loop by a transmission line extending through the shaft to a matching stub connected across the parallel conductors of the loop adjacent the cross-over. Adjustable matching condensers also bridge the parallel conductors. A uniform current distribution is necessary and to achieve this the primary loop diameter should not be greater than one-eighth of a wavelength and the secondary loop diameters not less than one-half of this. An alternative embodiment of the invention, Fig. 1 (not shown), employs a conventional circular loop with a condenser in series at the mid-point.
Patent GB-608332-A (GB)
Title: Elastic fabrics
IPC: D03D15/56
Filed: 1946-02-20
Abstract: Elastic fabrics are made by a process comprising the treatment of a textile fabric woven from fibres comprising filaments of a synthetic linear polyamide containing hydrogen-bearing amide groups and which may be further cold drawn at least 300 per cent with a solution comprising formaldehyde, an aliphatic alcohol and an oxygen-containing acid catalyst, and containing less than 20 per cent water and having a pH below 3.  The substantially undrawn polyamide fibres may be either warp or weft, and in the case of a fabric with two-way stretch are both warp and weft; preferably they are in the weft in a one-way stretch fabric.  The non-reactive fibre may be drawn, oriented nylon, cotton, mercerised cotton, rayon, linen, silk, wool or casein fibre.  Any weave, plain, twill, satin, figure, double or gauze may be employed.  Knitted fabrics may be treated.  The synthetic linear polyamides used have in general an intrinsic viscosity as defined in Specification 461,236 of at least 0.4, and the average number of carbon atoms separating the amide groups is at least two.  The solution of alcohol, formaldehyde and acid is applied for 15-75 minutes at a temperature of 50-90 DEG  C., preferably 60-80 DEG  C.  The formaldehyde is preferably used as paraformaldehyde, but trioxymethylene and other formaldehyde-liberating substances may be used.  Any primary or secondary aliphatic alcohol miscible with formaldehyde, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, secondary butyl alcohols being preferred, though allyl, methallyl, crotyl, benzyl alcohols, ethylene glycol, diethyllene glycol, cyclohexyl alcohol and glycerol are also useful.  The acid, in order not to cause excessive degradation of the polyamide, should have an equivalent conductance of less than 370 ohms-1 cm2, measured at 25 DEG  C. in 0.01 N concentration, 5-10 per cent oxalic acid is the most suitable, other acids being maleic, fumaric, mono-, di- and trichloracetic acids and p-toluene-sulphonic acid.  The reaction is allowed to proceed until at least 20 per cent, and preferably 35-55 per cent of the total hydrogen bearing amide groups are converted into N-alkoxymethyl groups, or in general until there has been some swelling of the undrawn filaments; the point of optimum reaction is the point of maximum swelling.  The fabric is quenched to stop the reaction, first in an alcohol, preferably that employed in the reaction, though ethanol and methanol may always be used, then in solutions stepped down to pure water in one or two steps.  In an example, a plain weave fabric with a cotton warp and a weft of undrawn nylon is immersed in an excess of a solution of 5 parts by weight methanol, 5 parts paraformaldehyde and 1 part anhydrous oxalic acid at 62-64 DEG  C. for 30 minutes.  It was removed and placed in methanol, then equal parts methanol and water, and finally in water. The width after treatment was 75 per cent of the original, but it could be stretched to 200 per cent of the original width with a 95 per cent recovery.  Specifications 461,236, 461,237, 582,517 and 582,518 are referred to.
