Title: Improvements in or relating to coaxial cables
IPC: H01B11/18
Filed: 1960-09-07
Abstract: 937,837. Air-spaced coaxial cables. R. C. MILDNER. Aug. 28, 1961 [Sept. 7, 1960], No. 30883/60. Class 36. An insulating structure for a coaxial cable comprises at least one strip or tape 1, 2 of insulating material corrugated for at least a marginal part thereof and arranged helically around and lying edgeon to the inner conductor with the corrugated edge adjacent the inner conductor. The edges of the strip or strips may be sinusoidally scalloped along the edge in contact with the inner conductor and if two tapes 1, 2 are used they may be formed with their corrugations 180 degrees out of phase and joined together along their lines of contact or alternatively one strip may be folded to form a similar structure. Rods 6 of rigid insulating material may be used to support the inner conductor radially. In a modification (Fig. 3, not shown) a coaxial cable has its inner conductor corrugated with a twostart helical corrugation and a corrugated strip is doubled over so that each edge follows one corrugation. The insulating tapes may be of polyethylene or polypropylene. Specification 608,147 is referred to.

Title: Improvements in and relating to the manufacture of strengthened glass
IPC: B32B17/08
Filed: 1928-10-25
Abstract: 322,598. Murray, H. D., and Spencer, D. A. Oct. 25, 1928. Compound transparent sheets.-To prevent discolouration by the sunlight of the celluloid used in composite glass, aesculin or a fluorescent salt of a cinchona alkaloid is used in the manufacture of the glass. A film of gelatine solution containing the fluorescent salt may be coated on to the glass surface to contact with the celluloid. In addition to this, the nitrocellulose sheet may be impregnated with a substance which inhibits decomposition or which forms colourless compounds with the decomposition products of nitrocellulose, e.g. sodium silicate and glycerine, and the celluloid used is of high viscosity. A further precaution is to use glass which is impermeable to ultra-violet light.

Title: Device for controlling ac motors
IPC: H02K17/16
Filed: 1975-07-24
Abstract: 1484523 Motors BEN-GURION UNIVERSITY OF THE NEGEV 24 July 1975 [28 July 1974 7 July 1975] 31004/75 Heading H2A A device for controlling an A.C. motor, e.g. on starting, comprises an electromagnetic field inducing coil and a conductive element having an opening leading to a space within the confines of the element, the coil being wound to surround the element and the space within the element so as to induce flux along the walls of the element, and the opening having a gap a defined by the formula a # #, wherein # is the wave penetration depth at the instantaneous frequency of the induced electromagnetic energy; the arrangement, in effect, increases the exposed surface area of the element, and increases the absorption of the induced energy. In the arrangement shown, wherein the field inducing coil is not illustrated, a tubular conductive element 12 has a longitudinal slot 14 along its entire length, and encloses one or more tubular elements 16 formed with or without slots. In Figs. 5-7 (not shown), tubular conductive elements, e.g. of iron, are provided with tapering openings, and in Figs. 8, 9 (not shown) bodies (18, 16) may be moved to vary the size of an opening in a conductor. In Figs. 10, 11 (not shown), projections (26, 32) are formed on the inside/outside of hollow conductors to increase the effective surface area. A labyrinth-like structure incorporating three coaxial tubes (36, 38, 40) is described with reference to Fig. 12 (not shown), and a parallel plate system (42, 44) with reference to Fig. 13 (not shown). Heat dissipating fins (48) may be used as in Fig. 14 (not shown). In Figs. 15, 16 (not shown), metal plates (56) or tubes (60) are moved relative to slotted conductive elements (12) to provide dynamic control of the absorption process, e.g. by suitably controlling motors (58) driving the plates/tubes (56/60). The arrangements described may be used with induction motors having wound or cage type rotors.

Title: Mild hydrofining of light virgin naphthas
IPC: C10G45/02
Filed: 1957-10-04
Abstract: Light virgin naphthas (boiling range C1 to 430 DEG  F.) are desulphurized by contact at 450 DEG  to 750 DEG  F. with not more than 30 SCF/Bbl. of hydrogen in the presence of a hydrofining catalyst, the hydrogen consumption rate being below 25 SCF/Bbl.  The pressure may be 50 to 800 p.s.i.g. and the feed rate 1 to 10 V/V/Hr. The feed may be unstabilized or stabilized by removal of C3 and lighter fractions.  The hydrogen may be pure hydrogen or it may contain up to 60 degrees of inert diluents and may be derived from other refinery processes, e.g. hydroforming. H2, H2S and C3- hydrocarbons may be removed from the product in a flash drum. Residual traces of H2S may be removed by caustic washing, e.g. with 2-5 wt. per cent of S0Be caustic alkali.  Preheating of the hydrogen is not necessary but it may be mixed with the feed before the latter is preheated.  Hydrofining catalysts mentioned are 5 to 15 wt. per cent molybdenum oxide and mixtures of cobalt oxides (2-6 wt. per cent) and molybdenum oxides (6-15 wt. per cent), both an activated alumina.  They may be regenerated at 900-1100 DEG  F. with an oxygen-containing gas.  In an example a C1-300 DEG  F. virgin naphtha was treated at 600 DEG  F., 550 DEG  F. and 500 DEG  F. with 30 SCF of hydrogen per barrel of feed at 225 p.s.i.g. and a feed rate of 4 V/V/Hr. using 10-14 mesh cobalt molybdate on alumina.  The hydrogen consumption was 12-15 SCF/bbl.

[Also in Division D1] Driving apparatus, e.g. for traverse guides in a double-sided textile winding machine, comprises a pair of cams 11 arranged side-by-side and mounted for rotation on parallel shafts 12, common power input gearing 14 disposed centrally between the cams and their shafts, individual driving connections between the input gearing and the cams, and respective followers 30 co-operating with the cams and guided to be reciprocated parallel to the shafts, the cams being relatively set so that each follower on one cam is out of phase with a symmetrically positioned follower on the other cam. The cams are rotatable relative to the shafts, and are driven by gears 15, 16, 17 and arm 18, from gear 13 driven by common input gear 14, which may be driven at a varying speed, e.g. in a sawtooth pattern with 10% variation, to prevent ribbon winding. Alternatively, angular speed variations of the individual cams may be produced by a lever mounted on gear 15, following a slot in gear 13 with one end, and driving cam 11 with the other. The cams are also displaced axially of the shafts 12, to prevent package-end build-up, by bevel gears 22 on the shaft and 23 rotating with the cam, driving a connecting link 27. Each cam may have a pair of followers, preferably nearly but not exactly 180 degrees out of phase, driving traverse guides for two rows of winding units on each side of a machine.

Title: Aromatic phosphine oxides
Inventor: COATES HAROLD
IPC: C07F9/53
Filed: 1961-09-01
Abstract: A process for the production of a tertiary phosphine oxide of the formula Ar2P(=O).  CHOH.R, where each Ar represents an aryl radical and R represents an aliphatic, aromatic or heterocyclic radical, such radicals Ar and R each optionally containing inert substituents, comprises reacting a diarylphosphine oxide with an aldehyde.  Those products in which R represents an aliphatic or heterocyclic radical, optionally substituted, are claimed per se.  The diaryl phosphine oxides may also be used in the form of their addition compounds with ketones.  The aldehyde may be used as such or may be liberated in situ by depolymerisation of their polymers or by decomposition of their bisulphite addition compounds.  The reaction may be carried out in an inert liquid medium, e.g. water, alcohols, ethers or hydrocarbons.  Room temperature or temperatures up to 150 DEG C. may be used.  An inert atmosphere may be provided.  The products are useful as plasticisers and lubricant additives.  Examples describe the preparation of diphenyl-2,2,2-trichloro-1-hydroxyethylphosphin oxide, diphenyl-1-hydroxybenzylphosphine oxide, diphenyl-1-hydroxypropylphosphine oxide, diphenyl-1-hydroxy-2-methylpropylphosphine oxide, diphenylhydroxy-methylphosphine oxide and diphenyl- 1-hydroxybut- 2-enylphosphine oxide.  Reference is also made to the use of ditolyl-, dixylyl-, dinaphthyl-, phenyl-p-tolyl-and di-(methoxyphenyl)-phosphine oxides and of bromal, pyridine-aldehydes and furfural as suitable starting materials.
