Filed: 1924-05-22
Abstract: 229,909. Nasmith, J. W. May 22, 1924. Combing machines. - In an arrangement of the kind described in Specification 188,611, in which a feed nipper is provided in the main nipper to draw back into the nipper a certain amount of the lap from behind the top comb before the main nipper closes, the lower jaw F of the feed nipper is suspended from the nipper frame N<1> by a link 6, and is connected by a pivoted arm 4 to a lever L<1>, L mounted on a pin 1 carried by the main nipper bridge B. The lower end of the lever arm L is connected by an adjustable rod 8 to a swivel-piece 9 carried by an arm 10 on a fixed shaft 11. The upper jaw F<1> of the feed nipper is carried by a lever 3 pivoted on the pin 2. The lever 3 at its lower end is connected to a spring S and carrier a bowl 13 adapted as the main nipper swings about its pivot N to come into contact with an inclined stop-piece 16<a>. The bowl 13 travels up the stoppiece 16<a> during the further movement of the nipper and the lever 3 is raised against the action of the spring S, which normally keeps the feed nipper closed. The stop-piece 16<a> is mounted on an arm 16 loosely mounted on a rock shaft 15, operated by a cam M on the comb cylinder shaft. The arm 16 is adjustably secured by a bolt 17 to an arm 14 keyed to the shaft 15. During the rearward movement of the nipper the arm 19 rests on a circular part of the cam 17 and the stop-piece is stationary, but during the forward movement the shaped part of the cam operates to move the stop-piece and alter the stage at which the feed-nipper is closed. The cam M can be adjusted upon its shaft. The arm 19 is free on the shaft 15 and can be adjustably secured to a plate 21 also loose on the shaft and adapted to be coupled to an arm 30 keyed to the shaft by the engagement of one or other of 'the holes 28, 29 with a hole in the arm 30, a pin passing through the holes. By these means the time of opening on the backward journey and the time of closing on the forward journey can be independently regulated. Each feed nipper can be adjusted relatively to the main nipper by means of the nuts on the rod 8, and the nippers of a series of heads in a machine can be simultaneously adjusted by turning the shaft 11 and securing it in position bv a bolt 26 in a slotted arm 25. The feed of any head can be arrested by pivotally mounting the stop-piece 16<a> on the arm 16 and supporting it by a notched latch engaging a lug on the arm, so that the piece 16<a> can be moved back to prevent contact with the bowl 13. To stop the feed in a series of heads in the machine the shaft 15 is turned until the hole 28 in the plate 21 registers with the hole in the arm 30 and the pin is inserted through these holes. '

Filed: 1968-03-15
Abstract: 1,156,434. Cooling electrical apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 15 March, 1968 [20 March 1967], No. 12629/68. Heading F4U. [Also in Division H1] In order to cool integrated circuit chips on a circuit board the circuit chips are each provided with a stud which extends into a well in a heat sink and is bonded to the wall of the well by a thermally conductive material having a low melting point. As shown in Fig. 1, semiconductor circuit chips 3, each containing a plurality of electronic circuits, are supported by leads 4 on printed circuit board 1, the leads 4 being supported by a ceramic collar 5, Figs. 1a, 1b, which is bonded to a molybdenum pad 6 which in turn is bonded to a copper, tungsten or anodized aluminium cooling stud 7. Each cooling stud 7 fits into a well 8 comprising a copper tube 9 mounted between head plates 10, 11 forming a heat sink. In order to have a good mechanical contact between the studs 7 and tubes 9 a low melting point material 16 is used to fill the interstices between the stud 7 and tube 9 such as low temperature alloys including indium, bismuth, tin, lead, gallium. By circulating hot water through the heat sink 12 via manifolds 13, 15 after the wells have been loaded, the temperature of the assembly is raised above the melting point of material 16 so that it melts to hold the studs in position in the wells 8. Cold water 17 is then passed through the system to solidify the low melting point interstitial material 16 and also cool the circuit chips 3. If hot water is not available, resistance wire heaters may be used in the heat sink 12. The wells 8 may have one end closed. A plurality of the heat sinks may be cooled or heated using the system of Fig. 3 in which the heat sinks 12a, 12b, 12c, 12d have their input manifolds supplied with cooling fluid from heat exchanger 20, expansion tank 21 and pumps 22, 23. The output manifolds 14a, 14b, 14c, 14d are connected through fail safe flow meters 25a, 25b, 25c, 25d. The temperature of the coolant is controlled by thermocouple 27 and controller 29 which latter adjusts valve 28 so that the correct mixture of hot and cold water is obtained at the input to the expansion tank 21.

Title: Process for the polymerisation of unsaturated organic compounds
IPC: C07C2/22
Filed: 1956-04-25
Abstract: Unsaturated organic compounds are polymerized in the presence of accelerators comprising anhydrous hydrogen fluoride and a preformed complex of boron trifluoride with iron, cobalt or nickel fluorides. The metals are preferably in their low valency states.  Specified unsaturated compounds are butadiene, isoprene, cyclopentadiene, cyclohexadiene, coumarone, indene, unsaturated aldehydes and ketones, ethylene, propylene which may contain inert materials such as propane or butane, 1-butene, 2-butene, isobutylene, pentenes, hexenes, styrene, methyl styrene, vinyl chloride, allyl chloride, acetylene and methyl acetylene.  Mixtures, e.g. of propylene and butenes, isobutylene and butadiene, or coumarone and indene may be employed. The catalyst may be supported on porous inert materials, e.g. activated charcoal, or on metal fluorides, e.g. aluminium, calcium, strontium, barium and magnesium fluorides, or metal oxides. Polymerization may be carried out continuously or batchwise, preferably under sufficient pressure to keep the reactants in the liquid state and to avoid loss of boron trifluoride from the complex. Unreacted monomers and a portion of the polymer may be recycled.  The hydrogen fluoride may be added continuously or intermittently, or dissolved in the monomer to form the catalyst in situ, and may be removed from the product by distillation or quenched with water and the product decanted and fractionated.  Polymeric hydrocarbons boiling in the gasoline range having high anti-knock values may be obtained.

Filed: 1948-05-07
Abstract: 651,538. Energy meters. MEASUREMENT, Ltd., and HEWLETT, S. J. May 7, 1948, No. 12644. [Class 37] [Also in Group XIX] Apparatus for transmitting to a remote point the indications of a meter comprises an electrical oscillator a, an amplifier g, and a coupling between them, the impedance of which is varied by revolutions of an element carried by the meter spindle e. The amplifier is electrically connected to a remote receiving system including means arranged to respond to the fluctuations in the amplifier output to count the revolutions of the spindle. As shown, the spindle carries a moving plate of a variable capacitor unit d, and the oscillator output is fed through a transformer to the unit d and a pre-set condenser c in phase opposition. The condenser c is set to cancel out the stray capacitance of unit d in the position of minimum coupling so that the signal sent to the amplifier g comprises separate wave-trains as shown. The amplifier output is fed through a filter h to pilot or power transmission lines i. In the remote receiving system, the wave trains pass through a filter j, amplifier k and rectifier m giving D.C. pulses which actuate a counter n by a solenoid and ratchet device o. A highfrequency carrier wave may be used for transmitting the wave trains. In another modification, the output of the amplifier g is rectified before it is transmitted. According to the Provisional Specification, an inductive coupling may be used in place of a capacitive one.
