Title: Improvements in the manufacture of fixed-gases and condensable hydro-carbon fluids from bitumenous materials by fractionate disintegration
IPC: C10J3/46
Filed: 1928-07-10
Abstract: 312,533. Meeze, A. G. July 10, 1928. Producers.-In a water gas process after a " blow " in which the air blast is enriched with powdered solid, or liquid hydrocarbons, and usual " run," the " run " is continued during a period in which a poor gas containing carbon dioxide and hydrogen is generated, and these gases are passed into another producer during the run or are subsequently passed into the same producer for conversion of the carbon dioxide content into carbon monoxide. By-products such as those usually obtained by cracking oils or by distinctive distillation are obtained during the second stage steam run, which may be modified by adding powdered coal or a hydrocarbon thereto, the fixed gases, after extraction of the condensable hydrocarbons, with or without steam, being passed into another producer or returned to the same producer. By diminishing the amount of steam, a gas rich in carbon monoxide may be obtained. Three water gas producers working in a cycle may be employed. Specification 2941/11 is referred to.

IPC: A43D21/12
Filed: 1953-07-22
Abstract: 748,657. Lasting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). July 21, 1954 [July 22, 1953], No. 20314/53. Addition to 682,130. Class 17 (1). The machine described in the parent Specification is provided with additional means for yieldingly assisting in urging the movable jaw 16 towards the fixed jaw 14. This prevents the movable jaw from rebounding from the fixed jaw when the former is moved to grip the stock. The power-operated means which yieldably moves the movable jaw towards the fixed jaw and yieldingly moves the jaws to tension the stock, then moves the movable jaw, against the action of the additional yielding means, to open the jaws, and returns the open jaws to starting position. The additional means comprises a spring 46 housed about a rod 40 in the bore 34 of the hollow carrier 28 between a shoulder 36 on the carrier and a head 44 of a sleeve 42 threaded on the rod. The length of the spring may be adjusted by rotating the sleeve about the rod, or springs of required strength may be substituted. Rod 40 is connected at the lower end to the pivoted lever 18 connecting the movable jaw 16 to the operating link 26. Spring 46 continuously urges the jaws together, and also ensures that the desired gripping force is obtained regardless of how light a pull is applied through the action of the gripperoperating spring. Rod 160 which has an adjusting nut 166 is connected to arm 120 keyed on shaft 94, and when the latter moves clockwise to operate the jaws rod 160 moves downwardly through holes in the thrust member 162 and the pin 164 journalled in lever 64. During reverse movement of shaft 94 at the time when the jaws are fully opened rod 160 moves upwardly and draws the resilient rubber bushing 170 to engage member 162, and thereafter shaft 28 and the grippers move downwardly at the same time as link 26.

Title: Common power supply for electrostatic precipitator banks with individual section control
IPC: B03C3/66
Filed: 1956-07-02
Abstract: 819,491. Supply and protective arrangements for consumption apparatus. APRA PRECIPITATOR CORPORATION. July 2, 1956 [July 18, 1955], No. 20426/56. Class 38 (4). [Also in Group XXXVII] An electrostatic precipitator 12 has a plurality of compartments-illustrated by 13, 14, 15, 16 each of which is successively cleaned by means of an apparatus 38, the high voltage supply to each compartment being reduced just before the cleaning operation and removed during the cleaning operation by means of apparatus under the control of a commutator type switch 60. The high voltage supply is taken from a common power supply 40-or alternatively from a number of separate supplies-to each precipitator compartment over an individual control unit 24-27 each of which contains a triode 46 in the high voltage line, the normal operating grid bias being supplied over a line 50. As a compartment is nearing the cleaning position one of a series of contacts 60a ... 60d is made thereby energizing the requisite relay 61 which closes its contacts 62 thereby increasing the negative bias of the triode 46 and so reducing the voltage applied to the respective precipitator electrode. As the compartment reaches the cleaning position one of the contacts 60e ... 60h is made thereby energizing relay 67 and closing its contacts 68 to further increase the negative bias on the triode 46 so as to cut the triode off and remove the voltage from the precipitator electrode. Should a flashover occur within the precipitator the increase of current through the control unit associated with the compartment will cause an increase in the voltage developed across an inductor 75A in the cathode circuit of the triode 46 in the unit. This will increase the negative bias on the triode and will thus suppress the flashover. Should, however, the flashover persist the increase in voltage across a cathode resistor 75 will energize a relay 76 to close its contacts 77 to increase the grid bias to cut off the triode 46. In an alternative embodiment the triode may be replaced by a tetrode. Specification 684,024, [Group XL (a)], is referred to.

Abstract: 1,095,250. Multi purpose bucket - lifting clamp assembly. G. G. TURNER (CATERPILLAR TRACTOR CO). May 14, 1965, No. 20576/65. Heading E1F. To ensure of efficient gripping of loads in a digger bucket load handling assembly in which objects are gripped between clamp arms swingably mounted on the bucket and the front of the bucket, the arms are secured along a torsion tube rotatably mounted in the side walls of the bucket and turnable with respect thereto by a jack-actuated linkage connected to the tube between the arms. A second linkage coupled to the tube controls movement, on appropriate rotation of the tube, of an ejector plate, forming the rear wall of the bucket, through the bucket. The hydraulic circuitry associated with the two jacks available to actuate the first linkage is such that only one is effective until a predetermined pressure in the circuit is exceeded. An accumulator is effective, when the jacks are locked on the clamp arms becoming operatively effective on an object, to deal with any subsequent minor slippage of the object between the bucket front and the arms.

Title: Improvements in or relating to web supply reel for printing presses
Inventor: MCWHORTER HENRY L
IPC: B65H16/02
Filed: 1952-08-18
Abstract: 716,938. Feeding webs. GOSS PRINTING PRESS CO. Aug. 18, 1952, No. 20739/52. Class 100 (1) A web supply reel assembly for printing presses comprises a supporting horizontal shaft, a pair of radially extending supporting arms mounted on the shaft to support between them at their outer ends a paper roll, means for applying torque to one end of the shaft to index it and move the arms from a loading position to a feeding position wherein the roll will be offset from the vertical plane through the shaft axis, means for securing one of the arms to the shaft against turning movement relative thereto, and means whereby the other arm will be capable of limited angular reflection relatively to the shaft so that torsional deformation of the latter will be compensated and the roll be maintained substantially horizontal. A central shaft 10 supports two spiders 18, 20, each comprising three arms 22 extending radially and angularly spaced at 120 degrees. Each pair of arms 22 supports a spindle 26 carrying a web roll P. The shaft is indexed through 120 degrees by means of a gear 28 when desired, so as to bring each roll successively from loading position to reserve and feeding positions, and since the gear 28 is driven by a small pinion, it acts to absorb the torque due to the weight of the rol!s. The weight of the rolls causes a torque in the shaft 4 between the spiders which causes a slight drop in the left hand end of the roll P in feeding position. The spider 20 is secured to the shaft by means of a hub into a series of bores in which are inserted set screws to engage opposite sides of a key extending along the shaft and accommodated in a keyway in the hub. In order to compensate for the drop of the end of the roll and to keep it substantially horizontal, the spider 18 is formed with a wider keyway to allow slight relative angular motion relative to the shaft. A torque collar 38 having a flange 40, is secured to the shaft, and an elastic torque-transmitting sleeve member 42 is bolted to the flange 40 and to the hub 56 of the spider 19. The member 42 is formed with a series of slots 64 to render it elastic. The arrangement is such that the horizontal arm 22 of the spider 18 drops to compensate for the drop of the corresponding arm 22 of the spider 20 Exact compensation occurs with a paper width of 56 inches, with undercompensation for longer rolls and over-compensation for shorter ones. In another form the spider 18 is secured to the shaft by means of set screws, and the arms 22 of the spider 18 are formed thinner than those of the spider 20, whereby the former have a torsional compliance causing a similar compensation.
