IPC: B61L7/06
Filed: 1930-03-10
Abstract: 357,103. Railway signals. VEREIN. IGTE E I S E N B A H N -SIGNAL WERKE GES., Siemensstadt, Berlin. March 10, 1930, No. 7775. Convention date, March 11, 1929. Void [Published under Sect, 91 of the Acts]. Drawings to Specification. [Class 105.) Comprises an electrical interlocking system in which, when the various points have been set to the position required for a particular through track, a track locking lever is thrown over to open a contact in the power line over which the return movement of the points motor could be effected and also to open a contact by which a magnet is de-energized to drop its armature and mechanically lock the points lever. The track locking lever has an indication lock magnet which is only energized if the various points are in the correct setting and thereby able to effect the energization of supervising relays the armatures of which complete the circuit to the indication lock magnet. When the track lever is thrown full over a contact is closed to energize a signal lever lock magnet which frees the signal lever to allow the signal to be put to clear and incidentally breaks the circuit of the track. lever indication lock magnet which lever is therefore locked.

Abstract: 362,274. Moulding wheel tyres ; vulcanizing-cores. GOODYEAR TIRE & RUBBER CO., 1144, East Market Street, Akron, Ohio, U.S.A. March 13, 1931, No. 7798. Convention date, May 22, 1930. [Classes 70 and 87 (ii).] A collapsable chuck for moulding wheel tyres comprises two pairs of segments hinged at their abutting ends at points 22, 23 to rigid arms 14, 15 mounted on a shaft 10. A sleeve 27, which is connected by toggle links 29, 34 to the free ends of one pair of segments, normally rotates with the shaft, but can be retarded by the application of a band brake 40 through the medium of a fluidpressure cylinder 51 controlled by a hand valve. Rotation of the shaft 10 in one direction when the sleeve is held, collapses the segments as shown in dotted lines, while rotation in the reverse direction automatically restores them to the full-line working position.

Title: New process for extracting oil from cashew-nuts and apparatus for carrying this out
IPC: B01D11/02
Filed: 1956-03-13
Abstract: <PICT:0823545/III/1> <PICT:0823545/III/2> A process for extracting oil from cashew nuts is characterized in that the extracting action proceeds from the inside of the nuts towards the outside.  This may suitably be achieved by subjecting the nuts to the action of high-frequency micro-waves for 5-15 minutes, or alternatively radio-frequency heating may be used. As shown, a suitable embodiment comprises an automatic feed container 1 (Fig. 2) which feeds the nuts on to endless conveyer belt 4 made of porcelain or heat-resistant glass.  The belt slowly passes between the two electrodes 3 which radiate at microwave frequency thereby heating the nuts from the interior towards the exterior.  The oil which flows out falls through the belt into container 7 which is placed beneath, and is then run off to storage.  On leaving this zone the nuts fall on to the perforated holders 9 of a bucket chain of another conveyer belt 8 (Fig. 3).  There the nuts are submitted to cleansing by hot water sprays 10 which remove any oil which adheres to the skin of the nuts. At the end of belt 8, the nuts fall, while still hot, into container 12 and thence into autoclaves 13 where they are treated for from about 1-3 minutes, after which they are discharged by compressed air, which also serves to separate the kernels from the skins.  The nuts are then thrust to the bottom of the autoclave, and on to a conveyer belt 14 which takes them to tables where the kernels and skins are sorted.

Gear-wheels, grinding and trueing teeth of; wheels.-In a gear-generating machine, the rolling action is produced by means of a cam, which with the gear-wheel undergoing treatment, is rotated alternately in opposite directions, and gives to the gear a reciprocating movement corresponding to the rotation. The machine comprises a base 1 carrying a standard 2 in which is journaled the shaft 5 of a grinding-wheel 6. The wheel is secured to the shaft by means of clamping-members 8, 9 and a nut 10, and the standard is arranged to allow of vertical and angular adjustment of the wheel. On a bracket 13 is supported an arm 15 having projections 16 carrying abutments 19 for the cam 29; the arm is adjustable vertically in the bracket. The abutments each comprise a plate 19<b> slidably adjustable in a box-like chamber 19a by means of a screw 19<d>, and each plate may carry a roller 19<c>. The base 1 is formed with ways 21 to receive a slide 20 carrying a spindle 22 to which the work, namely, a gear-wheel A, is secured. The spindle is rotatably mounted in sleeves 25, 26 which are rotatable in bearings 27, 28, and on the sleeve 25 is formed a flat face which engages a flat face on a lug 33<a> formed on the cam 29; by means of screws passing through openings 38<b1> in the cam and in the sleeve, and of a slot 29<c> in the cam, Fig. 7, the cam may be removed readily and another substituted therefor. Thecam is adjusted to contact with the abutments at points in a plane tangential to the pitch-circle of the gear-wheel, and the cam-surfaces 29b are formed so that, on rotation of the cam, the slide 20 reciprocates at a speed corresponding to that of the rotation to give correct tooth profiles. In order to index the gear-wheel, the sleeve 25 is provided with a disc 31 having a series of spaced openings 31a, and on the spindle 22 is a crank 32 having a pin 32<a> adapted to engage any of the openings. The spindle is rotated alternately in opposite directions by means of a worm 36 engaging a worm segment on the disc 31. The grinding-wheel may reciprocate, instead of the work. Specifications 187,663 and 197,631 are referred to.

Photo-conductors normally sensitive only to U.V. light may be sensitized to visible light by heating an intimate mixture of the photoconductor and an organic dyestuff to a temperature sufficiently high to cause a reaction between the photo-conductor and the dyestuff or a derivative thereof. As described, dry zinc oxide is heated together with a sensitizing dye at such a temperature and for such a time that an oxidation product or residue of the dye reacts with the zinc oxide to form a complex no part of which is water soluble. Various dyestuffs are listed, the preferred heating time and temperature range being given for each. They are:-Rhodamine B Extra, Patent Blue, Rose Bengal, Eosin, Erythrosin, Fluorescein, Malachite Green, Brilliant Green, Auramine, Crystal Violet, Rhodamine, Celliton Fast Pink, Bromophenol Blue, and Bromcresol Green. The quantity used may be in the range 1-10 parts by weight of dyestuff to 1000 parts of photo-conductor. To form an electrophotographic material the treated oxide is dispersed in an aqueous resin emulsion which is coated on to a suitable support and the water evaporated. A suggested support is clay-coated paper. A binder used is an epoxy ester-vinylacetate-crotonic acid copolymer.
