The water is introduced into the said system using boron trioxide as the dispersing medium. The boron trioxide, after drying, is maintained in an atmosphere of controlled humidity such that on subsequent introduction into the reaction system the boron trioxide/water mixture used as dispersing medium had a boron trioxide content of 55 to almost 100 mole per cent. The transport reaction is carried out at a water vapour pressure of between 2 and 3 mm. During the reaction the substrate bodies to be coated, 3, are heated to 700 C. in sealed ampoule 2, the gallium arsenide source 4 is heated to 775 C., and the B 2 O 3 /H 2 O dispensing agent 5 was heated to about 725 C. whereupon a layer of GaAs was formed on said bodies 3.

Crimped filaments of synthetic linear polyamides or copolyamides are made by passing the melt-spun polyamide or copolyamide filaments, immediately after cooling to the solidification point, about a godet, or godets, cooled to a temperature between 0‹ and 80‹ C. and then drawing off the filaments from the godet(s) at a rate which corresponds to the desired drawing ratio; the draw point being situated on the periphery of the cooled godet(s) or at a distance no greater than 10 cm. from the point where the filaments leave the cooled godet(s). Specified polyamides are nylon 6 and nylon 6,6 and the cooled godets are preferably at a temperature just above the dew-point. The crimped filaments thus obtained may be subjected to a thermal after-treatment to intensify and heat-set the crimps. As shown filaments 2 issuing from the spinneret 1 are passed through the thread guide 3 on to the cooled, movable godets 4, then to the spin-finish bath and roller 5 and then to the draw-off godets 6, which rotate at a rate sufficiently faster than rollers 4 to stretch the filaments by the desired movement. The filaments are collected on the wind-up bobbin 7.

Title: A method and device for dividing bread dough into cakes
IPC: A21C5/00
Filed: 1929-01-22
Abstract: 324,517. Pensotti, E. Jan. 22, 1929. Feeding and measuring. -Dough is divided by rotating members which detach portions from the mass by a spooning .action, then allow the detached portion to rest for a period and finally force it through a delivery slot which gradually opens and closes during the process. The uniformly-rotating roller B is fitted with one or more semi-cylindrical recesses C within which wedge-shaped blades G are rotated intermittently at a greater speed than the roller by mutilated toothed gearing. The blades lie so as to form a continuation of the surface of the roller while outside the hopper A, but rotate through the path indicated in dotted lines k while passing therethrough. Portions of dough are scooped from the mass into the recesses C, which are relatively large so as to hold the scooped portions without compressions, and are carried round to the point indicated in Fig. 6a where a discharge opening is just about to be formed between the knifeedge L and the axis of the member G, and where the latter member has advanced sufficiently to begin to push the dough from the recess. Fig. 6<c> shows the discharge opening closed by the member G; the opening having been first enlarged by the increasing distance of the axis of the member G from the joint L and then' decreased by the continued rotation of the member G. A handoperated worm gear is provided to vary the initial set of the mutilated toothed gear so as to vary the size of the portions delivered.

Abstract: 893,367. Variable capacitors. LEESONA CORPORATION. Jan. 21, 1959 [Jan. 27,1958], No. 2275/59. Class 37. [Also in Group XL (b)] An infra-red detector of the type in which a diaphragm forming one plate of a condenser is moved by expansion of an infra-red absorbing gas in a cavity, the diaphragm has a greater diameter than the cavity and is spaced slightly from the end of it. As shown, the detector comprises a housing 10 which may be of a conductive glass-sealing alloy closed at one end by a cap 14 and gasket 15 which retains in position an infra-red window 13. The infra-red absorbing gas is contained in a cavity 16 the end of which is spaced slightly from a diaphragm 18. The diaphragm has a minute hole to equalize the pressure on opposite sides. The diaphragm is clamped in position by bush 22 and nut 24. The effect of the space between the end of the cavity and the diaphragm is to allow a very small cavity (0.025-0.5 inch diameter) without the necessity for an extremely thin diaphragm for the purpose of acoustical matching. The second plate of the condenser is constituted by a head 34 carried on a rod 32 and sealed by bushes 38, 40.

[Class 38 (v).] Indicators.-A magnetically-operated interrupter for indicating the rate of movement of rotary or oscillating bodies has an armature and contacts controlled thereby arranged in a non-magnetic casing provided with a stationary magnetic member or members consisting of a polepiece or polepieces extending through the wall of the casing with their outer ends within the range of movement of a magnetic actuating device arranged to be moved in an intermittent manner past the pole-piece or polepieces, which thereby cause the attraction of the armature against the returning force. As shown in Figs. 1 and 2 the armature a is carried by an arm pivoted at b within a non-magnetic casing c through the lower side of which projects magnetic studs d, d<1> adjacent to the path of movement of a permanent magnet or magnets f secured by a strap g on a rotary shaft h. As the magnets f approach the polepieces d, d<1> their poles f<1> induct polarity so that the armature is attracted causing a contact o on the armature arm to engage a fixed contact o<1> completing the circuit of an indicating lamp n or, alternatively, of an audible indicating device such as an electric bell or of an electromagnetically actuated counting device. In order that the armature may dwell in its attracted position for an appreciable period a number of magnets may be arranged adjacent to each other as shown so that a succeeding magnet comes into effective cooperation with the polepieces before the influence of the passing magnet has passed out of inductive relation. Alternatively, if a single magnet is employed the polepieces may be suitably extended at their ends which come under the action of the magnet poles. The interaction between the magnets, polepieces and armature may be adjusted by mounting the casing c on a pivoted cam and providing an adjusting screw m for varying the gap between the magnets and stationary polepieces. The magnet or magnets may be attached to an oscillating body such as a lift.
