Title: Improvements in circular looms for weaving
IPC: D03D37/00
Filed: 1927-08-23
Abstract: 276,666. SÚry, C. Aug. 24, 1926, [Convention date]. Addition to 269,916. Selvages, forming; circular looms.-In the circular loom described in the parent Specification, wherein warp threads are omitted from one sector, selvages are formed on the fabric as shown in Fig. 1 by cutting the weft threads at the part free from warp threads, and then beating the cut threads into the shed and weaving them with the adjacent warp threads. When producing the selvage shown, the warp threads in the region of the selvages, that is the " adjacent " warp threads referred to, are controlled by heddle frames actuated by a cam additional to and separate from that for the other heddle frames, so that the warp threads near the selvages move twice as quickly as the other warp threads. After a shuttle has laid the weft 35 in the space free from warp threads, vertical tappets 102, 103 on arms 100, 101 on the vertical shaft 32 used for driving the shuttles engage and actuate cam levers 106, 107 on spring-controlled axles 104, 105 carrying beating combs 108, 109 at their lower ends. These combs are thus turned inwards as shown in Fig. 2 and push the weft on to a knife 112 whereby it is cut, the cut ends 35<a> following the movements of the combs and being beaten behind plates 113 whereby they are retained in position. The cam for actuating the healds for the warp threads near the selvages is described. In a modification, the weft thread ends are woven with the following weft threads.

Two forward and two reverse speeds are obtained from six gears arranged in pairs on parallel driving, driven and layshafts, the axes of which lie on the apices of a triangle. Loose gears 7, 8 on the driving shaft 5 are adapted to be alternatively clutched thereto by a sliding clutch member 13 and mesh respectively with a gear 27 fixed on a layshaft 25 and a gear 16 loose on the driven shaft 18. The gear 16 is also in mesh with a gear 26 fixed on the layshaft and is adapted to be clutched alternatively to another loose gear 17 in mesh with the layshaft gear 27 with the driven shaft 18. With the clutch sleeve 13 engaging gear 7 two forward speeds are obtained by moving clutch sleeve 23 on shaft 18 to engage gear 16 or gear 17. With clutch sleeve 13 engaging gear 8 two reverse speeds are obtained by the alternative engagement of clutch sleeve 23. The forward and reverse ratios may be equal. In a modified arrangement the gears 7, 8 on the driving shaft are secured together and axially slidable thereon into mesh with the gear 27 or 16 respectively. The gear 17 may also be axially slidable on the driven shaft 18 into or out of mesh with the gear 27. Friction clutches or positive synchronous clutches may be used instead of the dog clutches shown.

Filed: 1945-08-30
Abstract: 599,504. Rotary pumps. EBSARY, V. R. Aug. 30, 1945, No. 22338. Convention date, Aug. 10, 1944. [Class 110 (ii)] The pump is submerged in oil and comprises an eccentric rotor 41, pressed axially, to compensate for wear, by a spring 47 against an end wall 15, and a stator 23, provided with a vane 28 which is spring, or fluid, pressed to form pumping spaces alternately communicating with suction and discharge ports 33, 38. In Fig. 2, an arm 29 bears on the back of the vane. The vane may extend across the stator and be in two parts, pressed apart by springs. In Fig. 2, the rotor is driven through gearing 50, 51. An oil trap vessel 35 has an inlet pipe 57 which communicates with the pump inlet pipe 34. When the plunp is stationary, to prevent oil passing up the pipe 34 from the tank 10, due to vacuum in the vessel 35, a ball cock 55 falls and opens a valve 56 to allow communication between tanks 10 and 35. A number of inlet and discharge passages 32, 36 are provided along the length of the stator. An oil seal 58 is arranged to prevent air leaking in at a joint in the suction pipe 57. A groove 43 is sealed by oil and the rotor is cored out for lightening and balancing purposes. The discharge port 38 leads gas to a pipe 39 and an exhaust 40. An over load slipping-clutch 54 is provided. Fig. 5 shows a modification having a suction port 65 and discharge port 68 leading to ports 66 and 69 respectively. In addition, on the opposite sides of the stator, there are ports 71, 72 leading to an intercommunicating conduit 73.

Title: Improvements in electric pulse generating circuits
Inventor: BEZDEL WINCENTY
IPC: H03K3/37
Filed: 1954-08-04
Abstract: 780,232. Photo-cell circuits. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Aug. 4, 1955 [Aug. 4, 1954], No. 22644/54. Class 40 (3). [Also in Group XL (c)] The Figure shows a batch counting device of the type in which objects to be counted interrupt the light incident on a photo-cell tube PT. Cold cathode gas tubes VK2, VK3 comprise a bi-stable pair since if one tube conducts it causes the initially conducted tube to be extinguished because of the common anode resistor R1 and the charge on the cathode capacitor. The bi-stable pair is controlled by the auxiliary tubes VK1, VK4 which produce triggering pulses from the input circuit and share a common cathode resistor with their respective trigger pair tube. When the light beam incident on photo-cell PT is uninterrupted the voltage drop through resistor R3 is such that capacitor C2 which is connected across resistive potentiometer R3, R4, R5 between the H.T. supply and earth will have a charge which is insufficient to break down tube VK4. A similar charge will be maintained on capacitor C1 by the voltage developed across resistors R2 and R7. When the light incident on tube PT is interrupted by an object to be counted the anode of the photo-tube rises in voltage and capacitor C2 receives an increased charge such that tube VK4 is fired. Capacitor C3 now discharges through tube VK4 and the cathode voltage rapidly rises so that tube VK3 of the trigger pair fires and extinguishes tube VK2. Similarly as capacitor C5 is charged tube VK4 is extinguished and a steep-fronted pulse is produced at the cathode output lead 10 which may be used to drive a counting circuit. When the object to be counted passes out of the beam of light the voltage of the cathode of the phototube PT rises until the gap of tube VK1 fires. Tube VK2 of the trigger pair is thus fired and VK3 extinguished and a short output pulse is produced at cathode lead 11 which may reset the counter. The circuit is now in its initial condition and further objects to be counted produce pulses at lead 10 as previously described.

Title: A device for restraining relative axial movement of two coaxial members
Inventor: PETTINGER DONALD STANLEY
IPC: F16B7/10
Filed: 1964-06-01
Abstract: 1,104,754. Escapements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 24 May, 1965 [1 June, 1964], No. 22649/64. Heading F2X. [Also in Divisions E2 and G6] A linear escapement mechanism comprises three coaxial members which are relatively movable axially, the first member 21 being disposed between the second and third members and having two axially spaced arcuate slots 24, a coil spring 27 located in each slot and extending in the arcuate direction of the slot, the second member being in the form of a rack 22, the third member 23 having a cam surface 28 for engagement with the coil springs, and the third member being axially movable between two positions in one of which it displaces one spring, and in the other of which the other spring, into the path of the rack. As described the first member is a tube 21 having two sets of three equi-spaced arcuate slots 24 each containing a spring. In the first position of the member 23, as shown, the upper set of springs is displaced into the path of the rack. Raising of the member 23 first displaces the lower set of springs into the path of the rack and then allows the upper set of springs to move outwardly into a groove 29 and out of the path of the rack to allow limited axial movement of the latter, e.g. under spring action. Reciprocation of the member 23 between its first and second positions thus permits intermittent movement of the rack 22. If it is desired to allow free axial movement of the rack the member 23 is lowered from the position shown, to a third position in which the sets of springs each enter a groove 29 and are out of the path of the rack. The mechanism can be used to control movement of a control-rod forming part of a nuclear reactor control system.

Title: Fluidized bed contacting process
IPC: B01J8/34
Filed: 1957-07-17
Abstract: A method of contacting gasiform material and finely divided solids in a fluidised bed of solids, such as a catalyst, in a contacting zone wherein solids entrainment with upflowing gasiform material is relatively high and more solids are removed from said bed than are introduced with the gasiform material, comprises separating entrained solids from the entraining gasiform material, passing the separated solids to a stripping zone, maintaining the level of solids in said stripping zone higher than the level of solids in said fluidised bed of solids in said contacting zone and returning solids from said stripping zone to said fluid bed in the contacting zone to maintain a desired level of solids in the fluid bed.  In an example applied to the catalytic cracking of naphtha, kerosene, light or heavy <PICT:0845771/III/1> virgin gas oils, catalytic cycle gas oil, thermally cracked gas oil, deasphalted oil, solvent treated oil or reduced crude, the preheated oil is introduced into reaction vessel 10 through a line 12 and is admixed with catalyst from a regenerated catalyst stand pipe 14 having a control valve 16, and the mixture passes through a distribution grid 20 and into a short cylindrical member 22 which forms the reaction zone and is concentric with the main vessel 10.  The velocity of the hydrocarbon vapours is such that catalyst is drawn over into stripping zone 24 and the vapours pass into cyclones 38 and 48 and then through outlet 56 to fractionating equipment.  The level in the catalyst bed 30 is controlled by means of a differential pressure controller 72 which is operated in conjunction with pipes 74 and 76.  Similarly the level of stripped catalyst 42 is controlled by controller 78 operating in conjunction with pipes 75 and 77, as a result of which slide valve 70 is appropriately adjusted.
