Title: Improvements in or relating to machines for moulding plastic substances
IPC: B28B1/44
Filed: 1925-11-10
Abstract: 260,429. Fleming, W. A. Nov. 10, 1925. Moulds; perforating - machines.-Projections, ribs or lugs on the face of a tile are pierced in a direction parallel to the face of the tile by pins &c. operable by a handle which also controls a lifting- handle for the mould in such a manner that the lifting- handle is rendered inoperative until the piercing operation has been performed. As shown, a block a<1> supports a mould frame c within which the material is pressed by a plate d, pivoted at d<1> and furnished with a recessed portion d<2> to form a ridge b<1> on the tile b. Perforating-pins g are carried by a sliding member h operable by a handle i against the action of a spring j. To the front of the plate d is hinged a flap l constituting a lifting-handle. During the perforating-operation, bridge-pieces h<3> extending from the member h advance a plate k and bring projections k<1> thereon over the flap e rendering it operable for lifting the plate. When lowering the plate d for a further operation the plate k is returned by an auxiliary plate l slidably mounted upon the flap e which is subsequently disengaged by springs m. A cover o protects the perforating devices from grit &c. The sides of the mould c are profiled to the form of the tile and also to provide material for the ridge b<1>.

Title: Method of and apparatus for the electrolytic revivification of ferrocyanide of potassium formed in the purification of gases by oxidation of hydrogen sulphide with ferricyanide of potassium
IPC: C10K1/12
Filed: 1928-10-04
Abstract: 319,147. Brandt, R. Oct. 4, 1928. Materials for purifying.- Potassium ferrocyanide foimed in gas purifying liquor when the oxidation of hydrogen sulphide is effected by potassium ferricyanide is electrolytically reconverted to potassium ferricyanide. In a cyclic process, the spent liquor is first passed through large settling vessels to separate the coarse sulphur, and then enters the lower end 7 of an electrolytic cell where the potassium ferrocyanide is oxidized to potassium ferricyanide, the colloidal sulphur present having no effect on the reaction. The regenerated liquor passes out of the cell at the top end 8.

Title: Vehicle having a hydraulic lifting and lowering device for a working implement
IPC: A01D41/14
Filed: 1975-07-08
Abstract: 1509929 Hydraulic lifting and lowering device for harvesters AEBI & CO AG MASCHINENFABRIK 8 July 1975 [12 July 1974] 28622/75 Heading A1F A combine harvester has a hydraulic implement lifting and lowering device comprising an accumulator 13 connected to a lifting cylinder 3 of the implement I via a stop valve 12, only openable in a relieving position in which a limited force acts on the implement when the lifting cylinder is in lifting and holding conditions, and to the return conduit 8 of the sump 10 via a pressure limiting valve 14. The control lever 15 moves in a U-shaped guide to operate a three position reversing valve 14. The lever is biased by spring 23 and moves in the left-hand shank of guide 18 to attain lifting, holding and lowering positions. The relieving position is attained by moving lever 15 into the right hand shank since a switch 24 is depressed by a plate 22 and the valve 12 is electrically opened to connect the accumulator 13 to the cylinder 3. With lever 15 in the bottom right-hand position, the accumulator 13 is charged via conduits 6, 4 by pump 7, but moving lever 15 upwards closes off conduits 4, 6 and 8 in valve 5. For prolonged operation in the relieving position, the accumulator can be recharged when the pressure falls below a selected pressure by incorporating an electric switch 26 in the circuit of a pressure switch 27 and charge valve 28 located in the conduit 8. Electric switch 24 may be replaced by mechanical switching means.

Title: Ketals of methylenedioxypropiophenone
Inventor: CHODROFF SAUL
IPC: C07D317/54
Filed: 1959-08-24
Abstract: The invention comprises asymmetrical 3,4-methylenedioxypropiophenone butoxyethoxyethyl ketals of formula <FORM:0898581/IV (b)/1> where R is C1-6 alkyl or tetrahydrofurfuryl-2.  They are prepared by adding halogen, preferably chlorine or bromine, across the double bond of isosafrole and reacting the product simultaneously or subsequently with an excess of the alcohol corresponding to R to give an a -(methylenedioxyphenyl)-b - halopropyl "R" ether.  This is dehydrohalogenated with potassium hydroxide in an alcohol or glycol to give an a -(methylenedioxy-phenyl)-propenyl "R" ether and butyl carbitol is added across the double bond of this under the influence of an acid catalyst to give the desired ketal.  The products are pyrethrin synergists (see Group VI).  Intermediate compounds prepared in examples are: dichloro- and dibromo-isosafrole; a -methoxy-, a -ethoxy-, a -butoxy- and a -tetrahydrofurfuryloxy-b -bromodihydrosafrole; a -methoxy- and ethoxy-b -bromodihydrosafrole; a -methylenedioxyphenylpropenyl methyl, ethyl, butyl and tetrahydrofurfuryl ethers.ALSO:Pyrethrin compositions contain as synergists asymmetrical 3,4-methylenedioxypropiophenone butoxyethoxyethyl ketals of formula <FORM:0898581/VI/1> where R is C1-6 alkyl or tetrahydrofurfuryl-2.  (For preparation see Group IV (b)).  Preferably 2-4 mg. of ketal is used per mg. of pyrethrin, but amounts up to 8 mg. may be used. Conventional compositions e.g. in mineral oils, aqueous emulsions or on solid carriers may be used. The ketal may be added by grinding with the pyrethrin source material.  An additive synergistic effect is observed with sesamin and sesamolin.

Title: Improved method and apparatus for periodic strip feed
IPC: B65B41/18
Filed: 1956-09-27
Abstract: 834,033. Photo-electric control. HOLLER, W., and HOLLER, F., [trading as HOLLER GEB.]. Sept. 27, 1956 [March 31, 1956], No. 29591/56. Class 40 (3). In a bag-making machine comprising a periodic strip feed device controlled by optical scanning of impressed marks &c. on the strip, the periodic feed is carried out successively in equal steps each slightly greater than the impressed marks distance, but each time an impressed mark and the optical scanner coincide an electrical impulse is released causing a single shorter length of strip to be fed, after which the impressed mark setting again approaches step-by-step the optical scanner until they again coincide. The strip is fed between a sprung pressure roller 1 and a feed roller 2 mounted on a shaft 4 driven by a crank 6. A return pawl on the top of the shaft prevents backward motion of the feed roller when the shaft 4 and associated free-wheel 5 are set in reciprocating rotation. When an impressed mark coincides with the optical scanner a magnet 28 actuates a stop device 10 on which impinges a second crank 7 mounted on the shaft 4, and thus the return rotation of the shaft 4 is curtailed. A telescopic rod 8 surrounded by a compression spring 11 connects the crank 6 with a crank-pin 9. This pin 9 is driven in eccentric motion imparted from a driving shaft 39 through bevel gears 12, 13, shaft 14, crank disc 15 and a plate 16 which is radially movable on the disc 15; radial movement of the plate 16 causes an alteration in the stroke of the pin 9. Such radial movement and consequent alteration of the stroke of the pin 9 can be effected during running of the machine by means of a lever 22 connecting the plate 16 with an axially movable guide head 20 which co-operates with a spindle nut 19 actuated by a hand wheel 27. The hand wheel 27 is also connected through chain drive 34 to the shaft 30 carrying the stop device 10.
