Title: Improvements in the method and apparatus for profiling pieces of wood
Inventor: DIMTER ERWIN
IPC: B27M3/00
Filed: 1970-02-12
Abstract: 1,240,988. Working wood. E. DIMTER. 12 Feb., 1970, No. 6720/70. Heading B5L. A method of preparing pieces of wood in readiness for joining them end to end comprises assembling the pieces of wood in parallel on a work-table 12, with their leading ends 31 flush, profiling the ends 31 by moving a milling cutter 16 or the like past the ends, conveying the pieces to an adjacent table 38 on which their rear ends 39 are aligned, profiling the ends 39 by the milling cutter or the like, and applying glue to the profiled front and/or rear ends. In apparatus described for performing the method each piece of wood is fed to a saw 2, which squares its leading end and cuts out any flaws and then is advanced by a conveyer 4 to a stop 5. When the piece of wood contacts the stop 5 a cylinder 6 is actuated which pushes the piece, against the action of a counter cylinder 11 onto an assembly table 8. When a pack of pieces is assembled on table 8 the pack is moved on to the work-table 12 and then advanced in the direction of arrow 15 until the ends 31 lie in the working plane of the cutter 16. The cutter 16 moves in the direction of arrow 17 to position 32 and forms prongs or a chamfer on ends 31. Cutter discs and/or saws 18, 19 in front of, and/or behind the cutter 16, or variably spaced cutter discs 20 remove waste and trim the prongs. An apparatus 40 may apply glue to the cut ends 31. A bracket 33 then advances to push the pieces on to the adjacent table 38 with their ends 39 flush. Springs bear down on the pieces to ensure that the shorter pieces are not carried along with the larger ones by friction during this movement. The cutter 16 is then moved again to cut the ends 39 and the apparatus 40 moves to apply glue thereto. Alternatively the apparatus 40 is stationary and applies glue to the ends 39 as the pieces are moved on to a table 44. The direction of this movement, arrow 42, is at a small angle to the direction of movement 17 of cutter 16 so that the pieces do not again contact the cutter. The prepared pieces are fed in turn from table 44 by a conveyer 46 into a press 45 where they are assembled into an endless strip. A contact 60 ensures that the conveyer 46 only moves when there is a piece of wood to be moved into the press.

Abstract: 1,066,030. Removing meat from poultry legs. CAMPBELL SOUP CO. Feb. 17, 1966, No. 6954/66. Heading A2U. In removing meat from the legs of poultry, the legs are suspended from hooks 36 pivotally mounted between spaced apart conveyer chains 34 at loading station 42 and carried past meat stripping stations 70 and 72 to station 76 where the stripped leg bones are ejected from the hooks 36 and passed via shoot 26 to a conveyer (not shown). At station 70 where most of the meat is removed, the legs are engaged by stripper bars 90 resiliently mounted on pivoted members (not shown), the members being pivoted apart to allow the leg joints to pass between the bars 90, this pivotal movement being controlled by cams operating in timed relationship with the speed of the conveyer chains 34. The meat stripped at station 70 drops into trough 122 and it is chilled as it is moved successively through troughs 122, 124 and 126 by elements 140 on conveyers 138, the troughs being supplied with cooled brine solution from tank 146 by pump 152. The chilled meat drops on to conveyer 158. At station 72 any remaining meat is removed from the bones by subjecting the bones to jets of fluid from nozzles supplied with cooled brine by pump 182 and is passed to conveyer 158 by shoot 174. The meat is drained and then rinsed by spray 186 on conveyer 158, the drained fluid and rinsing fluid being returned to tank 146 by tanks 164 and 190 and pipes 192 and 166. The meat is then dried by subjecting it to air pressure sprays by means 194 and to suction by means 202. The dried meat drop on to delivery conveyer 22.

Title: Process for the manufacture of crystalline sodium-d-pantothenate
IPC: C07C233/46
Filed: 1942-05-26
Abstract: Crystalline sodium d-pantothenate is obtained by reacting the sodium salt of b -alanine with (-)-a -hydroxy - b  : b  - dimethyl-g -butyrolactone by heating under anhydrous conditions, and crystallising the fused product from a solution in an aliphatic alcohol, having not more than three atoms of carbon in the molecule. The reaction itself may also be effected in the presence of the alcohol.  In examples, the sodium salt of b -alanine is refluxed in ethyl and isopropyl alcohol with (-)-a -hydroxy-b  : b -dimethyl-g -butyrolactone and the sodium d-pantothenate crystallised out after filtration.  In a further example, the reactants are fused together and the product dissolved in ethyl alcohol and crystallised. Reference has been directed by the Comptroller to Specification 552,581.

Title: Improvements relating to the recovery of thiocyanates
Inventor: DWYER JOHN
IPC: C01C3/20
Filed: 1959-03-04
Abstract: Thiocyanate is recovered from aqueous waste liquor by addition of a mineral acid, e.g. sulphuric acid to the aqueous waste liquor followed by distillation under reduced pressure, the initial concentration of thiocyanate being equivalent to 2-30% w/w sodium thiocyanate, the molar ratio of mineral acid added to thiocyanate in the liquor being from 0.25-3.0 and the distillation pressure being from 1 mm. to 30 mm. of mercury.  The aqueous waste liquor may require dilution or concentration to bring the thiocyanate concentration to the desired value and further treatment may be administered between acidification and distillation.  Thiocyamic acid may be collected together with water distilled off, or may be collected in suitable alkalis or by other well known means. Examples are given in one of which 99 gms. of liquor are diluted with 225 gms. of water before 16.6 ccs. of 98% sulphuric acid are added thereto. The resulting acidified liquor was distilled at a pressure of 2 cms. of mercury and 99.8% of thiocyanate present was recovered, partly as sodium thiocyanate.
