Title: Improvements in and connected with brush holders for dynamo electric machines
IPC: H01R39/38
Filed: 1926-10-05
Abstract: 282,909. English Electric Co., Ltd.,. and Hassler, E. H. H. Oct. 5, 1926. Brush-holders; improving commutation, auxiliary means for. - Brush-holders in dynamo-electric machines are protected bv easilv removable and renewable arcing blocks which are provided close to the commutator in the regions where arcing occurs and are so mounted as to protect the adjacent parts of the brush-holders against the action of arcs which may arise on the commutator. In the form shown, the arcing blocks 8, Fig. 1, of copper, or other material of high conductivity for arc-quenching, are secured by means of a groove and tongue 9 and countersunk screws 10 to the brush box 1. The under surfaces of the blocks preferably bend away from the commutator, as shown in Fig. 1, and the blocks preferably abut on each other in a row, as shown in side view in Fig. 2, in such a way that any one may be removed for renewal or repair. The end blocks are rounded off at 15, 16 in addition to being curved on their faces 14 above the commutator. Arc-resisting partitions 12, 13 may adjoin the blocks 8 and brush box to separate the brush gear from the commutator. The brush holders, which are of known type, combine tubular members 4 adapted to be locked at any position in the upper parts 3 of the holders and enclosing guidespindles 5 which are attached to caps 6 on the brush tops. Compression springs 7 are enclosed between the caps 6 and the ends of the tubular pieces 4.

Abstract: 861,570. Coin-freed vending apparatus. FISHER & LUDLOW Ltd. July 16, 1959 [July 31, 1958], No. 24769/58. Class 27 A coin-freed vending machine, particularly for packaged meals, has a pair of endless conveyers 34 with their descending runs close together and each conveyer has platforms 45, 46 with spaced gaps 56 which clear fingers 55 on a stationary platform 53 and deposit the packages there for removal by a slide 28 having a handle 58 accessible from outside the machine. The conveyers are housed in a heated or refrigerated cabinet and a coin release unit 52 is provided on an extension 50 of the platform for freeing a bar 73 which has a pin 74 extending into a slot 72 formed in the base of the slide 28. When the slide is pulled out, a right-hand wing 62 on the slide displaces a lowermost package 76 from the fingers 55 and at the end of the outward movement the pin 74 is moved by the inclined portion 69 of the slot 72 to displace the bar 73 and pivot a lever 77. The top end of the lever moves into latching engagement with a notch on a catch 84 pivoted on a link 79 connecting two escapement levers 85, 86. During the last part of the return movement of the slide 28, the slot 72 moves the pin 74 and bar 73 in the opposite direction and the lever 77, now latched to the link 79, moves the levers 85, 86 so that dogs 91, 92 engaging escapement wheels 42 allow the conveyers to descend by a distance corresponding to the spacing between teeth on the ratchet wheels. At the end of this movement, the catch 84 is tripped by a fixed abutment and the levers 85, 86 are returned by a spring 93 to initial position against stops 95, 96, the conveyers lowering through another stage so that a package is deposited by the left-hand conveyer on the platform 53 ready for withdrawal by the lefthand wing 62 of the slide. Feeler arms may detect that only a few packages remain and they open a coin-return shoot to a slot 25 and illuminate a warning light to indicate that reloading is required. The machine is re-loaded from the back and the top platforms may be loaded with weights 89 instead of packages. Rails 29 for supporting trays 31 are provided on the front of the machine.

Abstract: 909,910. Packaging machines. RICHARDS, D. K. Oct. 20, 1960 [July 20, 1959], No. 24912/59. Class 94(1). A packaging machine for hard fruit &c. comprises a hopper for feeding a quantity of fruit into a tray, held in a horizontal moveable drawer, during an opening movement of the drawer, and discharging the filled tray through the base of the drawer into a carton beneath. Fruit is fed from the discharge shoot 12 of a grading machine into a closed hopper 5, the capacity of which is variable by adjustment of a plate 13 along rods 15 and which is pivotally mounted at 9a. The hopper has rollers 32 resting on cam faces 6 on the sides of the drawer 3. The drawer 3 containing a tray is pulled to the left, Fig. 1, permitting the hopper to tilt and discharge fruit into the tray beneath the plate 13. An extension 31 of the hopper prevents fruit entering it from the shoot 12 in this position. The bottom of the drawer comprises flaps 16 hinged at 17, which are lowered by means of a handle 18 operating levers 23-27, and enter the mouth of a carton beneath, guiding the loaded tray as it falls into it. The carton is supported on a platform 20, pivoted at 21. The flaps are then raised, the drawer closed and the cycle of operations repeated. When the carton is full, a handle 19 is pulled which inclines the platform 20, and the carton moves away along a conveyer 22.

Title: Process for dyeing ethylene glycol polyterephthalate fibres
Inventor: MINGASSON GEORGES RAYMOND HENR
IPC: C09B43/124
Filed: 1961-07-12
Abstract: Dyes containing at least one amino group and at least one sulphonic group attached to the N atom of the amino group and free from sulphonic groups linked in any other way are employed to dye fibres of polyethylene glycol terephthalate. The dyes may be of the monoazo or anthraquinone series.  In the first case the sulphamic group may belong to the diazo or coupling component; it may be introduced before or after coupling.  In the second case the sulphonic group may be introduced by treating an aminoanthraquinone with anhydropyridinium sulphate or anhydro-a -picotinium sulphate.  Such dyes are described in Specifications 901,403, 900,186 and 611,320. Examples are given.ALSO:Fibres of polyethylene glycol terephthalate are dyed by applying thereto, by heating and in the presence of an acid or a substance yielding an acid, a dyestuff containing at least one amino group and solubilised by at least one sulphonic group attached to the N atom of the amino group but free from sulphonic groups linked in any other way.  The sulphonic group is said to be progressively hydrolysed during the dyeing thus forming an insoluble dye.  Suitable dyes are described in Specifications 901,403, 900,186 and 611,320.  The dyeing may be effected in the presence of a dispersing agent, e.g. a fatty alcohol/ethylene oxide condensate at the boil or above at superatmospheric pressure; in the first case a carrier e.g. o phenylphenol, may be coemployed.  Examples are given.

Title: Improvements in the production of lubricating oils from olefines
IPC: C10G50/02
Filed: 1936-09-19
Abstract: Olefines substantially free from other substances are polymerized for the production of lubricating oils by first treating at high temperature and pressure in the presence of catalysts which yield a highly unsaturated product, then treating the product as a whole with aluminium chloride, boron fluoride or similar catalyst, decanting the oil from the tar, and purifying it by fuller's earth.  For the first stage the catalyst may be phosphoric acid, phosphorus pentoxide, phosphates, chromates, and perchlorates, such as aluminium, chromium, cerium and barium phosphates, barium and lead chromates, barium perchlorate, formic, molybdic, and phosphomolybdic acids, ammonium phosphomolybdate, aluminium mercury couple, and cobalt-thorium mixtures.  In examples; (1) ethylene is treated with ammonium phosphomolybdate on alumina gel at 49 atmospheres pressure and 350 DEG  C. and the product is stirred at 155-160 DEG  C. with aluminium chloride and aluminium, the product being decanted and treated with fuller's earth; (2) ethylene is treated with chromium phosphate on alumina gel at 350 DEG  C. and elevated pressure and the product is treated at 50 DEG  C. with boron fluoride and decanted and purified as before; (3) the second stage in the preceding example is effected with boron fluoride, nickel, and some water.
