Abstract: 412,502. Cigarette-maldng machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(American Machine & Foundry Co. ; 511, 5th Avenue, New York, U.S.A.) Dec. 22, 1933, No. 36102. [Class 130.] A cigarette-collecting mechanism for continuous-rod machines comprises means for forwarding a succession of cigarettes endwise and a suction device arranged adjacent to the path of the cigarettes and serving as a brake to stop forward movement of the cigarettes to permit transverse delivery. As shown, the cigarettes are delivered from the machine between forwarding belts 11, 12. Alongside the belts is a rotating collector drum 13 formed with axially extending grooves 13<a> provided with ports 15 communicating with a suction chamber S within the drum. The chamber S extends from a point adjacent to the belts 11, 12 to a point at which the cigarettes C are removed by delivery belts 16 running in grooves in the drum. The chamber S is formed in a stationary block 40 and communicates with a suction conduit 37 held by a spring 38 in substantially airtight relation to a flange 39 on the drum 13. The cigarettes are preferably moved positively into engagement with the grooves 13<a> of the drum by a pusher 14, which is given an orbital movement by means of crank pins 14<a> carried by discs on shafts 28, 29 driven through spiral gearing 26, 27 from a shaft 23, which also drives the shaft 17 of the drum 13 through gearing 18 ... 22 and the drive pulley of the belt 11 through spiral gears 30, 31. In a modification, suitable for the delivery of cork-tipped cigarettes or for use with very high speed machines, the pusher and the drum are long enough to transfer two cigarettes at a time to two aligned suction grooves on the drum, from which they are delivered to two sets of transverse delivery belts.

IPC: B01F23/10
Filed: 1974-08-16
Abstract: 1428943 Dispersing gases in liquids F L WALTER 16 Aug 1974 36187/74 Heading B1C A method of dispersing a gas as fine bubbles in a liquid comprises mixing the gas (e.g. pure oxygen) with a condensible vapour (e.g. steam) and injecting the mixture into the liquid. The gas and vapour may be mixed in a simple conduit (see Fig. 1, not shown). In the apparatus shown steam is conducted through a converging nozzle 50 to a low pressure chamber 52 where it aspirates waste water from the conduit 39, or the mixture discharges through a diverging nozzle 53 into a high pressure chamber 43 and thence through a nozzle 56 into a waste water tank. Oxygen is added to the steam through conduit 34, to the waste water through conduit 35, and/or to the mixture in the high pressure chamber through conduit 36; and steam may be further added to the oxygen through conduits 40 and/or 47; a mixture of 90% steam and 10% oxygen is advantageous. Alternatively the condensible gas may be a fluorocarbon.

Filed: 1929-11-27
Abstract: 340,108. Tempering sheet glass. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY ET CIREY, 1 bis, Place des Saussaies, Paris. Nov. 27, 1929, No. 36390. Convention date, March 13. [Class 56.] A process for tempering sheet glass consists in heating a sheet, whilst suspended in a vertical position, to a uniform temperature corresponding to that at which the glass commences to soften, and then subjecting the hot glass to the action of powerful jets of air directed at right angles upon the two faces of the sheet until complete cooling of the glass is effected. The sheet is suspended by two hooks which engage in shallow notches formed in its vertical edges. The suspended sheet is inserted in a metal box or casing which is placed in an electric furnace, the purpose of the box being to provide a uniform temperature in the space about the glass. When a sheet has attained a uniform temperature in the neighbourhood of 550‹-620‹ C., it is rapidly removed from the furnace by means of the suspension device and is chilled immediately by means of powerful air jets impinging at right angles on its two faces. The nozzles of the air jets are so arranged that regularly distributed centres of cooling are established on the faces of the sheet.

Title: Simultaneous production of a plurality of identical semiconduc tor components each having a p-n junction from a single semico nductor wafer
IPC: G01R31/26
Filed: 1971-08-05
Abstract: 1332586 Testing semi-conductor components SIEMENS AG 5 Aug 1971 [18 Aug 1970] 36754/71 Heading G1U [Also in Division H1 In a method of simultaneously producing plural identical semi-conductor components each having at least one p n junction in the face of a single wafer and thereafter subdividing the wafer, the individual components are tested by bringing the wafer face in contact with an electrolytic bath Fig.1 (not shown) capable of anodic oxidation wherein a potentiometrically controlled direct current is applied between a cathode and the rear face of the wafer, which is retained and contacted by a suction tube. An insulant layer protects the blocking junctions intermediate the front and rear of the wafer from the electrolyte. A control voltage appears between the faces of the wafer, and the fronts of the elements whose breakdown voltage is in defect of this are anodically oxidized or have material removed therefrom so as to permit recognition, by colour change or removal of electrode material; and satisfactory elements remain unchanged. The rear of the wafer may have a common electrode if it comprises plural zones inset to a common n zone. If however plural n zones are inset to a common p zone, plural contacts are applied to the individual zones of the rear surface with current reversal, the common zone is immersed, and oxidation or removal occurs on that surface in positions opposed to faulty components. Alternatively the wafer may be the cathode to a solution of a salt of the contact electrode metal, and metal deposition occurs on the faulty components; or the p n junctions of the system may receive alternating current excitation whose peak approximates the required current tolerance, when deposition will occur in satisfactory components; the wafer surface being connected to form a negative electrode and the junctions biased in the sense of current flow. In e.g. an array of planar diodes Fig.2 (not shown) formed by diffusion of p type zones into a n type wafer through apertures of a S i O 2  mask, the p zones contact the electrolyte while the n zone is negatively connected in relation to the p zone. A shortcircuited element is coated with metal on negative halfwaves which is removed on positive halfwaves, while an intact element is reverse biased during positive halfwaves so that the metal remains deposited. Negative peaks exceed the diode diffusion voltage while positive peaks do not exceed its breakdown voltage. A. C. may be superimposed on positive D.C. by connecting a rectifier across an A. C. fed potentiometer with negative peak voltage exceeding the applied direct voltage to metallize those elements whose reverse voltage exceeds the positive direct voltage; the sum of which with the positive peak does not exceed the reverse voltage.

Abstract: 1401571 Glove for safety suit L A CALHENE and PIERCAN SA 3 Aug 1973 [10 Aug 1972] 37045/73 Heading A3V [Also in Division B4] A cuff for a flexible, sealed glove, bag or mitten either as used to give access to the interior of sealed enclosures, e.g. glove boxes, or which forms the extension of the sleeve of a protective or safety suit or a sealed suit worn by an operator who partially or totally enters a closed space, comprises an annular portion 15 connecting a bead 12 with the body 13 of the glove 1 or like member and having inclined sides 16, 17 which result in an abrupt and considerable increase in diameter after the bead 12 followed by a narrowing before joining the body 13. As shown, the glove 14 is borne by an armband 2 which is also used for securing a sleeve 3 at the end remote from the glove 1 by means of a bead 4 engaging in a groove 5, the sleeve being part of a protective suit or a garment worn by an operator having access to the interior of a sealed enclosure. The sleeve 3 is connected at its other end by a bead 6 to a rim 7 forming part of the wall 8 of the sealed enclosure. The armband 2 may, however, be connected directly to the wall 8 of the enclosure. The glove 1 is locked on the armband 2 by means of an outer clip or ring 19 applied between the bead 12 and a raised rim 18 at the end of the armband. In order that the glove 1 may be replaced, a new glove 1a fitted via an end bead 12a on the end of a cylindrical ring 20 is provided within the enclosure. The ring 20 is positioned around the armband 2 (Figure 2 not shown) and the used glove 1 is turned inside out so that it'comes inside the sleeve 3 and the cuff 15 is at least partially flattened. The clamping ring 19 is withdrawn while the bead 12a of the glove 1a is released from the rim 22 of the ring 20 via notches 23 and takes up a position on the armband 2 immediately behind the bead 12 of the glove 1. The particular shape of the cuffs of the two gloves 1, 1a is such that direct contact between their sides which might result in one glove being locked frictionally to the other is avoided. The ring 20 is then withdrawn and the clamping ring 19 fitted to secure the bead 12a of the glove 1a on the armband 2. Finally, a tractive force applied to the glove 1 causes the bead 12 to pass over the rim 18 so enabling withdrawal of the glove 1 to be effected.
