Abstract: 1326336 Tracing grinding wheels WERKZEUGMASCHINENFABRIK OERLIKENBUHRLE AG. 14 March 1972 [17 March 1971] 11721/72 Heading B3D An apparatus for dressing a grinding wheel 19 comprises a copying template 10 for guiding a tool 14 along a prescribed path of travel, the template having control surfaces 6a for controlling movement of the tool during dressing of the wheel and testing surfaces 58 which control movement of the tool past means 22, 23 for indicating the position of the tool with respect to the prescribed path of travel of the tool. The apparatus consists of a housing 1 mounted for rotation in a vertical pivot 2 and laterally supported by rollers 3. A carriage 4 is guided for vertical movement along guides 6 by rollers 5 and at its lower end is connected by a parallel linkage 7 to a support 8 having a pin 9 engaging the template 10. The support extends through an opening 37 in the housing and is connected by a web 11 and dovetail 12 to a carrier 13 for the tool 14 which has a diamond tip 15 horizontally and vertically adjustable by screws 17, 18. The carriage is vertically movable by a linkage 30, 34 connected to an hydraulic piston-and-cylinder device 24. The indicator means consists of a rod 22 which is pivotally mounted at one end 39 and is acted upon by a spring 45 so to bear against surfaces 46a, 46b of a plate 44 secured to the housing 1. The rod also bears against the stems of a pair of indicators 50, 51. When the carriage 4 is moved downwardly by actuation of the device 24, the follower 9 first moves over the testing surfaces 58 of the template to engage the tool 14 with the rod 22 which is deflected from the surfaces 46a, 46b. If the deflection is too small or too large, due, for example, to wear of the tool, the deflection can be read in the indicators or the indicators may operate warning lights. The tool can be adjusted by the screws 17, 18. If the deflection is correct, the follower 9 then moves over the control surfaces 60 to move the tool so as to dress the wheel to the correct profile. The wheel may be used to grind a plurality of cutters 21 for a front cutter head of a gear-cutting machine, the cutters being carried by a saddle of a grinding machine past the grinding wheel.

Abstract: 1,221,347. Electro-photographic development. EASTMAN KODAK CO. March 11, 1968 [March 13, 1967], No. 11762/68. Heading G2H. A method of forming an electro-photographic image comprises imagewise exposing a photoconductive layer carried by an electrically conducting layer, electro-phoretically depositing toner particles on the image areas, and treating the photo-conductive layer in a manner which inhibits deposition of toner in non-image areas. In one embodiment, shown in Fig. 1, an image of a transparency 26 is projected on to the photoconductive layer 22 carried on a conductive layer 21, which is placed in and insulated from a metal developing cassette 10, and a field applied between layer 22 and a transparent development electrode 19 causes negatively charged toner particles 13, in an insulating organic liquid 12, to be deposited on the image areas. Toner deposition in non-image areas is inhibited by pre-charging layer 22, e.g. with a corona charger, or by a first development step using charged toner particles of low colour density, followed by development with toner particles of high colour density. In a second embodiment Fig.2 (not shown), the photo-conductive layer is exposed through a transparent conductive backing, and positively charged toner particles are used. In a contact printing embodiment Fig.3 (not shown) a pre-charged photo-conductive belt (37) is exposed to a source (34), the image electrophoretically developed by contacting the surface of a developer (11) and the developed image transferred to a paper web (43). The photo-conductive layer 22 may be organic, e. g. a triphenylamine compound or inorganic e.g. selenium, the conductive backing layer 21 may be aluminium or transparent, conducting cellulose acetate, and the development electrode may be of Nesa glass. Many examples are given of toner preparation and composition.

Title: Improvements in or relating to bandspread tuning devices for radio apparatus
IPC: H03J3/10
Filed: 1946-04-17
Abstract: 613,152. Radio receiving circuits. PHILIPS LAMPS, Ltd. April 17, 1946, No. 11782. Convention date, July 1, 1941. [Class 40 (v)] In a band-spread tuning arrangement in which the wave-band is determined by connecting one of a number of inductors to a circuit comprising a variable condenser and one or more fixed condensers, further inductance is added in series with the variable condenser or with each of the condensers in order that the absolute value of the frequency range in two or more bands may be equalized. In Fig. 1, switch 5 selects the inductor 2, 3 and 4 required for the wave-band. A further inductor 7 is connected in series with the band-spread tuning condenser 6 and this reduces the effective variation in capacitance of the condenser, the reduction being greater at higher frequencies. By this means the absolute value of the frequency range is equalized in two bands, the deviation in the third being small. Equalization in the third band also may be obtained by the addition of further condensers and inductors 8 to 11 as shown in Fig. 2. In an alternative arrangement, Fig. 3 (not shown), for higher frequencies, the inductors are formed by the connecting leads between the components.

Title: Improvements in or relating to sewing machines
IPC: D05B15/00
Filed: 1936-04-28
Abstract: 476,044. Sewing machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., BARTON, F., and LINEHAM, R. A. United Shoe Machinery Co. de France (in part)] April 28, 1936, No. 12034. [Class 112] In a curved-hook needle boot-sole sewing- machine of the kind described in Specification 447,680, the work support engages the work at the opposite side from that at which the needle first penetrates, and the support has an automatic withdrawing movement in timed relation to the needle, during feeding. The invention is shown as applied to a turn-shoe machine which differs from that described in Specification 447,680 in that the external work support 33 supports the work in all the phases of stitching. The support 33 is mounted on trunnions 31 at one end and has a block 35 for engaging the work adjustably secured at its other end. This block presses the upper A against the sole B and has teeth for this purpose. The work is guided by the edge gauge 29 which is adjusted to or from the block by a screw. The support 33 has a pair of toes 39 having horizontal under portions which, when the support is in its raised and operative position, Fig. 2, lie flat against corresponding faces formed on the spindle 19 to prevent the support 33 from swinging forwardly and to afford support against downward thrust. Near their forward ends the toes 39 have a horizontal pin 41 carrying a roller 43 engaging a cam slot 45 in the upper end of a plate 47 mounted on a pin 49 in the spindle 19 and receiving a pin 51 on a lever 55 to form a toggle device similar to that described in Specification 447,680 so that the support 33 may vary in height according to the thickness of the work. When the spindle 19 is drawn downwards after the needle has pierced the work to release the upward pressure of the work support, to enable the needle to feed the work, the pin 49 also moves downwards. The pin 51 remains stationary. As the spindle 19 descends, therefore, the cam plate 47 rocks rearwardly. During the greater portion of the downward movement of the external support 33, the position of the cam slot 45 which is concentric about the pivot 49 of the cam plate, moves rearwardly along the roll 43 and maintains the support 33 in its upwardly extended position. Just before the work support reaches its fully lowered position the straight portion of the slot engages the roll 43 and rocks the support 33. The path of the block 35 is indicated by the dotted line XY, Fig. 2. When the spindle 19 rises for the formation of the next stitch, the support 33 rises to press the work against the foot 71. A modified form of work support 371 is shown in Fig. 12, where the work-releasing movements are imparted by the lever arrangement 377, 379, 385. Specifications 4173/12, 317,921, [both in Class 112], and 350,444 also are referred to.
Patent GB-1062113-A (GB)
Title: Production and recovery of hydrogen halides
IPC: C01B7/19
Filed: 1964-03-23
Abstract: Halogenated organic materials are converted into normally gaseous products comprising CO2 and hydrogen halide by intimately mixing a halogenated organic material with a gaseous medium which contains oxygen and hydrogen (e.g. steam) and passing the resultant mixture through a constricted zone into an expanded zone to effect any necessary atomization of the halogenated organic material.  The atomized mixture is then passed into a combustion zone to achieve substantially complete combustion to a product comprising CO2 and hydrogen halide and containing substantially no free halogen, free carbon or organic compounds. The initial intimate mixing of organic material and gas may be effected in a first constricted zone followed by an expanded zone where it is mixed with a second gas (e.g. air) before being atomized and passed to the combustion zone. A furnace when used for carrying out the <PICT:1062113/C1/1> process is also claimed.  Fig. 1 is a vertical cross-section of the furnace, having a cylindrical outer fire wall 1 and inner cylindrical fire wall 9 faced with refractory material.  The gaseous mixture enters at 14 through the mixer nozzle assembly 20 consisting of expanded and constricted zones.  The gases required for combustion enter at 15.  The furnace may be preheated to 900 DEG  C. and combustion may take place at 1300 DEG  C.  Fig. 3 (not shown) illustrates the mixer-nozzle assembly on a larger scale.

Filed: 1959-04-10
Abstract: 917,758. Indicating leakages in tubes. ROLLS-ROYCE Ltd. March 21, 1960 [April 10, 1959], No. 12308/59. Class 99(2). Apparatus for indicating flow to or from any of a number of pressure spaces 10, 11, e.g. defined by double-walled tubes in a nuclear reactor for receiving fuel elements due to a change of pressure therein, comprises two sets of conduits A, B, C and a, b, c, each set of conduits having connections to all of the pressure spaces so that each conduit of the set has connected to it a corresponding group of the spaces and so that each space is connected to one only of the conduits in the set, and the groups in the two sets being such that no group in one set has more than one space in common with any group of the other set, there being in each conduit an. associated flow-sensitive element F arranged between a pressure source and its group of connections to the pressure spaces, which flow-sensitive element is adapted to give a signal on occurrence of flow in that conduit. Each flow-meter may comprise a platinum wire mounted coaxially within a conduit and connected to resistors in series to form a bridge circuit associated with a galvanometer. In operation, the wire is heated by the electric current flowing therethrough and on the flow of gas through the conduit the upstream end of the wire is cooled thereby causing the resistances of the two halves of the wire to become different and so that such gas flow is indicated by a deflection of the galvanometer. All the wires located in the conduits forming one set are connected in parallel with one another across a voltage source, and the mid-points of adjacent pairs of wires have galvanometers connected therebetween.
