IPC: A23N4/02
Filed: 1926-07-12
Abstract: 277,770. Leonhardt, H. July 12, 1926. Stoning fruit. - A fruit-stoning machine comprises a rotating member A carrying segments B hinged thereto, the segments being provided with rubber fruit - holding sockets C at the bottoms of which cupped ejector rings are positioned. The rotation of the member A brings the sockets C into registration with the stoning dies H and, after stoning, the segments fall, as shown, for ejectment of the stoned fruit, this being effected by rods F on the ejector rings striking against a plate G. The sockets are split to permit the movement of the rods F and are formed with bottom flanges which are held by keeper members screwed to the segments B. Stops I prevent the rods F from being totally withdrawn. The stones and the stoned fruit fall into independent shoots.

Title: Method of and means for pasteurising milk
IPC: A23C3/033
Filed: 1929-06-07
Abstract: 329,193. Melballe, T. June 7, 1929. Preserving milk.-Milk is pasteurized by passage through pipe coils 3, 5 surrounded by jackets 4, 6 through which is circulated in opposite direction to the milk a heating liquid from and to a heating tank 14, the temperature in the coils being regulated by co-operating thermostatic devices one 23 disposed in the pipe system and the. other 25 in the tank 14. In the construction described, the milk is fed by gravity from a tank 1 in which a constant level is maintained by supply from a tank 29 through float valve 30. The milk passes through pipe 2 to a preheating coil 3 and thence to the pasteurizing coil 5. The milk is finally cooled to normal temperature in a coil 7 having a jacket 8 through which cooling water is passed, entering by pipe 12 and leaving by pipe 13. Valves 9, 10 allow the milk flow to be regulated. The heating liquid, e.g. water or oil, in tank 14 may be heated by steam supplied through a pipe 13 and diffuser 20 through a valve 26 controlled by the thermostatic devices 23, 25, and passes from the tank through pipe 15, pump 16, valve 27 and pipe 17 to jacket 6, returning from jacket 4 through pipe 18. A byepass 28 is provided through which the hot liquid can be supplied directly to jacket 4 at the beginning of the process, the flow being regulated by valve 27. Tank 14 is connected through a pipe 21 with a relief tank 29 and a discharge pipe 22 to allow for expansion. The heating liquid may be passed through the pipe coils at a greater speed than the milk to prevent too great a drop in temperature.

Title: Improvements in the manufacture of derivatives of polyhydroxy compounds
IPC: C08B11/00
Filed: 1935-06-22
Abstract: Fibrous cellulosic materials are etherified under substantially anhydrous conditions in the presence of organic bases, by means of compounds of the general formula RX or R2SO4 as the sole etherifying agents, where X is a halogen atom and R is an alkyl or aralkyl hydrocarbon radicle or a carboxy or esterified carboxy substitution derivative thereof.  Suitable etherifying agents are dimethyl and diethyl sulphates, methyl and ethyl chlorides, benzyl chloride, chloracetic acid, bromacetic acid, ethyl chloracetate, and ethyl bromacetate.  As organic bases, methylamine, ethylamine, pyridine, piperidine, aniline, and methyl anilines are particularly useful. The etherification is preferably carried out in the presence of a water-immiscible diluent.  In an example, cellulose is soaked in diethylamine, pressed, and introduced into an autoclave together with benzene and diethyl sulphate.  In a second example, cellulose is treated in an autoclave with ethyl chloride in the presence of pyridine and ether.  The products are suitable for conversion to other derivatives of cellulose, as is described in Specification 458,596.  According to the Provisional Specification, the process is applicable to the etherification of other polymeric hydroxy compounds, e.g. polymerized vinyl alcohol and starch. Specifications 207,562, 249,173, 263,938, [all in Class 2 (ii)], and 414,751, [Group VIII], also are referred to.

Patent GB-438648-A (GB)
Title: Improvements in and relating to sewing machines
IPC: D05B73/12
Filed: 1935-06-24
Abstract: 438,648. Sewing-machines. HUGHES, R. M., 72, Cannon Street, London.-(International Button Hole Sewing Machine Co. ; 502, Harrison Avenue, Boston, U.S.A.) June 24, 1935, No. 18059. [Class 112] In a machine for sewing imitation or uncut buttonholes, the feeding means produce a relative movement between the stitchforming mechanism and workholding means after completing the sewing to break the thread and then produce a relative movement in the reverse direction to bring the parts back to starting position. In the form shown, the invention is shown as applied to a machine in which the work is held on a stationary frame 1 and the stitching mechanism is carried in a frame 5 movably mounted on the work frame. The stitch frame 5 has the usual arm 6, needle bar 7, and under portion 10, carrying the turret. 11 for the loopers. The stitch frame is moved to-and-fro by the usual cam 14. Figs. 2 and 3 show the parts in the position they take when the machine is brought to rest before starting, the needle being in position a and the follower 16 occupying the position in the cam groove 17 shown in full lines in Fig. 3. The stitch frame 5 is at its rearmost position. The cam 14 rotates in a clockwise direction, Fig. 3, when the machine is started and the wheel 25 is clutched to the shaft 23 to give the cam its initial high speed movement. The cam shifts the frame 5 forwards to bring the needle to position b from which the stitching starts. During this interval the cam 14 has turned to bring the follower 16 from a<1> to b<1>. As the cam 14 continues its rotation, the follower 16 travels from bl to c<1>, moving the stitch frame to bring the needle to the position c, during which time the stitches 70, Fig. 4, are made along one side of the buttonhole. At position c, the turret and stitch-forming mechanism are turned to sew round the end 76 of the buttonhole. Further continued movement of the cam 14 causes the follower 16 to travel from c<1> to b<2>, giving the stitch frame 5 a reverse movement to bring the needle from c to b to make the stitches 71. When the cam has turned so that the follower 16 has travelled to the point b<2>, the needle is back at b and the stitch mechanism is brought to rest. The clutch wheel 25 is again coupled to the shaft 23 to produce a rapid rotation of the cam 14 for the remainder of the machine cycle. During further rotation of the cam 14, the follower 16 travels from b<3> to d<1>, giving the stitch frame a second forward movement to carry the needle from b to d and break the upper thread at the last stitch. As the cam 14 completes its rotation, the follower moves from d<1> to the starting point a<1>, bringing the needle from d, through b back to a. The wheel 25 is then disengaged from the shaft 23 and the parts are ready for the next cycle.
