Title: Catalytic Composite useful for the Oxidation of Mercaptans in Sour Petroleum Distillates
IPC: C10G27/10
Filed: 1979-07-23
Abstract: Mercaptan oxidation catalysts for sweetening sour petroleum distillates comprise a metal chelate (e.g. a phthalocyanine) and a quaternary compound of the structural formula   <IMAGE> where each R is an alkyl, cycloalkyl, aryl, alkaryl or aralkyl radical containing up to 20 carbon atoms, R<1> is a substantially straight chain alkyl radical containing from 5 to 20 carbon atoms, R2 is aryl, alkaryl or aralkyl, and X<-> is the chloride, bromide, iodide, fluoride, nitrate, nitrite, sulfate, phosphate, acetate, citrate, tartrate or hydroxide anion, impregnated on a solid adsorptive support. The catalytic composites are especially used for trating sour petroleum distillates containing the more difficultly oxidizable mercaptans in the presence of an oxidizing agent and an alkaline reagent (which may be the above quaternary ammonium compound in which X is hydroxide).

Title: Stud manipulating device
IPC: B23P19/06
Filed: 1979-10-03
Abstract: A device for inserting and removing studs 16 from bores 19 in a workpiece, for example a nuclear reactor vessel, comprises manipulating devices for operating on individual studs, each capable of tensioning a stud 16, slackening a working nut 17 on the stud, and subsequently removing the stud from the bore. A ring 92 has dogs 93 which can engage working nut recesses to interlock with the nut against relative rotation. Motors coupled to the ring 92 rotate the working nut. A top nut 51 is coupled to the motors to rotate the nut and screw it onto the stud 16. The top nut 51 with other device parts can be raised and lowered on a tube 61 by a hydraulic actuator. A hydraulic load cell 52 between the top nut and a stool 53 on the workpiece is pressurised to tension the stud 16 by means of the top nut 51 and thus facilitate rotation of the working nut 17 when tightening or slackening. A dog clutch mechanism 26 engages a stud end fitting 25 against relative axial and rotational movement. The mechanism is raised and lowered on a guide member 36 by an actuator 38. The mechanism has a tubular member 42 and the drive coupling for the motors to the top nut 51 includes a tubular member 61. The tubular members 42 and 61 carry teeth 43 and 85 which are engaged when the top nut 51 is raised and the mechanism 26 is lowered, to provide a coupling between the motors and the mechanism for rotating the stud. <IMAGE>

Each of four channels in the transmitted may comprise a limiter 58, a frequency-to-voltage converter 60 and a voltage-to-frequency converter 62 giving a pulse train 63 having a prf in the range 40 to 400 Hz and related to the band pass filtered audio signal 57 in that channel - the pulse trains 63 of all four channels all being in the same 40 to 400 Hz range. In each channel a monostable 70 gives a pulse train 71 with a prf. determined by the signal 63 and a pulse width determined by the output of a log. amp. 68 which receives the outputs of filter 50 via a rectifier 66. In transmitter 74, the signals 71 from channels 1 and 3 modulate a 12 MHz carrier, and signals 71 from channels 2 and 4 modulate a 31 MHz carrier, the modulated RF signal from channels 1 and 2 being applied to coil 76 and those from channels 3 and 4 to coil 78. Each channel in the receiver has a tuned circuit with a respective pick-up coil (81 to 84, Figs. 3, 4) and passes the detected signal to electrodes located at a position in the cochlea responsive to an audio frequency in that frequency band passed by the filter 50 in the corresponding transmitter channel. The cochleal implant (Fig. 5) may comprise wires in a silicone elastomer body, each wire terminating in a ball acting on an electrode. Reference is also made to apparatus comprising a four channel implanted receiver and a single channel transmitter, and to apparatus comprising a single channel transmitter, a single channel receiver and a single channel electrode fixed at or adjacent to the round window membrane of the ear. <IMAGE>

Title: Automatic pack-forming and pack-cartoning
Inventor: CLARKE FRANK PERCY
IPC: B65B5/02
Filed: 1982-03-24
Abstract: A succession of products is automatically cartoned by collating a desired number of the products 11 into a row and/or stack ("the pack") of desired form; surrounding the pack with a cage 15, 18a, 18b, (19a) and (19b) which holds the pack in that form; forming a carton closely around the pack-holding cage; and withdrawing the carton from the cage, or the cage from the carton, to deposit the pack within the carton without substantially altering the pack form. The cage specifically illustrated and described comprises a top plate 15 having hinged flaps 18a, 18b and (19a, 19b)-Fig 2 (not shown) each of which is large enough to overlie the adjacent pack side defined by the collated products when folded down around the pack. The completed carton specifically described and illustrated is an open- topped display carton containing filled sachets. In a modification, Fig. 6 (not shown), the cage is used to return a mass of sweets whilst cartoning. <IMAGE>
Patent GB-2098489-A (GB)
Title: Signal processing apparatus
IPC: A61F2/72
Filed: 1982-05-17
Abstract: Signal processing apparatus comprises an amplifier 1 receiving a signal from a mammalian body on input terminals 10. The amplified signal is passed via a rectifier 2 to an integrator 3. The output of the integrator 3 is fed to a trigger stage 4, which responds to reset the integrator 3 each time the integrator output reaches a predetermined value. Each time the integrator 3 is reset, the trigger stage 4 emits a pulse which is amplified by an output stage 5, which thus provides an output pulse train, the amplitude of the pulses being adjustable up to 100 volts. The repetition frequency of the output pulse train is thus proportional to the average amplitude of the original signal at the input 10, and the output signal can be fed directly to a body to control a bodily response, or alternatively may be fed to a prosthesis, to simulate a bodily response. The output of the trigger stage may alternatively pass to a frequency-to-voltage converter to give an output with an amplitude related to the average amplitude of the input at terminal 10. The invention has more general application, in processing an input signal to provide a pulse train wherein the interval between each two successive pulses is proportional to the amplitude of the input signal since the first of the two pulses. In a modified stimulator, rectifier 2 is omitted, integrator 3 is arranged to give an output determined largely by the predominating polarity of the input, and trigger 4 may have positive and negative level triggers giving pulse trains with frequencies respectively dependent on positive and negative input signals. In a further variant, the circuitry in Fig. 1 following integrator 3 is omitted, and reset pulses are applied to the integrator 3 at a constant rate fast enough to prevent saturation therein, so that the integrator outputs immediately before a reset pulse is proportional to the average level of the input signal between reset pulses, and this output is applied to a sample and hold circuit or an analog to digital converter. <IMAGE>

Title: Gas lasers
Inventor: FINN HARRY JOHN
IPC: H01S3/034
Filed: 1982-06-01
Abstract: A transversely excited gas laser has a gas-filled chamber formed by a rigid platform 8 of a low-expansion material and an envelope 13 sealed to the platform, the laser cavity mirrors 11, 12, 13 (and the electrodes 5) being mounted on the platform. The envelope 13 may be made of fused quartz and bonded by an epoxy resin to the platform 8 and functions solely as a wall of chamber 4.
