Title: Finger board racker apparatus for well drilling
IPC: E21B19/14
Filed: 1968-11-20
Abstract: 1,214,346. Boring earth &c. BYRON JACKSON Inc. 20 Nov., 1968 [4 Dec., 1967], No. 55153/68. Heading E1F. A derrick has a pipe rack including a finger board 55 comprising sections 68, 69 having fingers 105 .. 109, 111, 112 and 81, .. 87 respectively. The spaces 113, 95 in the sections are for drill collars 54 and the remaining spaces are for drill pipes 53, the collars and pipes being respectively held in the spaces by individually actuated latches 101, 97. The bottoms of the pipes and collars engage projections 158 on a base 156. A racker 51 having a gripper 121 on an extensible arm 118 carried by a carriage 122 is mounted above the finger board, and a similar racker 52 having a gripper arranged for an additional vertical movement is mounted below the board. After a drill string 26 is lifted through the rotary table 61 by elevators 44 until a stand 49 is clear of the slips 59, the string is locked in the table by the slips, the elevators are removed and the stand is gripped by rackers 51, 52, the head of the racker 52 being in its lowermost position. Power tongs 58 are operated to detach the stand, and the head of the racker 52 is raised to position the stand as shown. Both rackers are operated to bring the stand opposite and then into a space, the racker 52 lowers the stand onto a projection, the respective latch is operated to hold the stand, and the rackers are removed from the stand. The process is repeated for pulling the string, and the reversed process is repeated for making a string. The apparatus is mounted on a drilling vessel and may be controlled by a computer.

Title: Horizontal deflection circuit for cathode ray tube
IPC: H03K4/64
Filed: 1968-11-29
Abstract: 1,220,360. Transistor sawtooth circuit. GENERAL TELEPHONE & ELECTRONICS Inc- 29 Nov., 1968 [29 Nov., 1967], No. 56846/88. Heading H3T. A horizontal deflection circuit for a cathoderay tube comprises a transistor 10, damping diode 11, deflection coil 12 and capacitor 13 connected to a supply 14 as shown, driven by a sawtooth current waveform (Fig. 6) commencing with an initial magnitude of turn-off polarity and ending with a turn-on polarity of magnitude substantially equal to the initial magnitude. As described, a driver transistor 20 is driven by a 15À75 kHz. sine wave at 28, 29 so as to become conductive during part of the negative half cycle. A sawtooth current is thus built-up by inductor 23 and is supplied to the base of the output transistor 10. Towards the end of the negative half cycle of the sine wave at 28, 29, driver transistor 20 becomes non- conductive so that inductor 23 and capacitor 24 execute a half cycle of oscillation which is arranged to remove stored carriers from the output transistor 10 and so terminate the sweep in deflection coil 12. A half cycle of oscillation now occurs between coil 12 and capacitor 13. The oscillation is terminated by damping diode 11 which passes deflection coil current during the commencement of the next sweep. The sawtooth current in inductor 23 is now accommodated by reverse base emitter breakdown of transistor 10. Diodes 21 and 22, which minimize the loading of the circuit on the oscillator connected to terminals 28 and 29, may be omitted and replaced by the collector-base junction of transistor 20.

Title: Method and Apparatus for the Extrusion of Multi-Component Synthetic Resinous Bodies
Inventor: SCHRENK WALTER JOHN

Abstract: 1,166,169. Extruding multicomponent film and sheet materials. DOW CHEMICAL CO. 14 Dec., 1967 [22 Dec., 1966], No. 56866/67. Headings B5A and B5B. A process for the extrusion of a sheet comprising layers of different synthetic resinous materials comprises dividing at least two streams of different synthetic resins into a plurality of substreams, varying the rate of flow of at least some of these sub-streams by shear forces and recombining all the sub-streams to form one main stream which is extruded. The two streams of material enter the die 10 from sources 16 and 19. Material from source 19 emerges from orifices 36 in distribution block 26, the rate of flow of these sub-streams being invariable. Material from source 16 fills the chamber 12 and emerges from the distribution block 26 through passages 31. The rate of flow through the passages 31 is controlled by rotating shear producing means 40, the angular velocity of these shear producing means being individually adjustable to produce the desired flow rate. The combined stream (located at 23) which comprises a column of alternating layers of the two materials is extruded through the fishtail nozzle 28, producing a layered continuous sheet. A sheet in which the thicknesses of alternating layers are in arithmetical progression may be produced with the above apparatus. In an alternative embodiment, the shear forces are produced by members reciprocating against the upstream end of channel 81.

Abstract: 1,193,910. Xylenes. JAPAN GAS-CHEMICAL CO. Inc. 13 Dec., 1968 [15 Dec., 1967], No. 59295/68. Heading C5E. In a process in which m-xylene is extracted from xylene mixtures as a complex with HF and BF 3  and is subsequently isomerized to more useful xylenes, part of the HF and BF 3  required for the extraction is provided in combined form by isomerizing at least part of the m-xylene extract without prior decomposition and recycling undecomposed isomerizate to the extraction, and part of the HF and BF 3  is provided in free form. To achieve the latter, either part of the extract phase is decomposed before isomerization, the resulting HF and BF 3  being utilized, or if all of the extract is isomerized without prior decomposition then part of the isomerizate is decomposed. Preferably the amount of HF and BF 3  recycled as undecomposed isomerizate is 20-70% of the amount withdrawn in the extract. The extraction, isomerization and decomposition steps may all be carried out in the presence of a diluent; suitable ones are specified. Three different arrangements of apparatus are described, in one of which some m-xylene may be recovered as product, but in the others of which m-xylene is continually isomerized and recycled and therefore not recovered as such.
