In the case of the rear seat belts, each slotted tube extends up the associated door pillar and across the roof with the guide tube of the other rear seat belt disposed alongside and a single motor 14 is used selectively to drive each flexible cable independently. Conveniently the slotted tubes, guide tubes and motor are all formed in an inverted U-shaped trim unit which is attached to the vehicle above the normal trim. An additional belt displacement device may be provided to displace the upper inboard end of the seat belts simultaneously with the above described mechanism. The motor 14 is automatically started by opening or closing a door of the vehicle, tipping a front seat back rest in the case of the rear seat belts in a two door vehicle or by switches in the seats themselves.
Patent GB-743425-A (GB)
Title: Improvements in or relating to the production of heating oil blends
IPC: C10L1/04
Filed: 1953-04-28
Abstract: A heating oil blend is prepared by washing a cracked mercaptan-containing petroleum heating oil fraction with aqueous caustic alkali prior to any contact of the fraction with air, partially sweetening a virgin mercaptan-containing petroleum heating oil fraction and blending the respective treated fractions.  The caustic alkali washing procedure for the cracked component of the blend may in some cases be supplemented by a more severe treating operation such as that involving sulphuric acid. Also the virgin heating oil fraction subjected to partial sweetening may in some cases contain a minor proportion of cracked components boiling in the heating oil range (about 350-750 DEG F.). The partial sweetening may be effected by treatment with aqueous caustic alkali in the presence of air or by treatment with hypochlorite.  Apparatus is described in which a crude petroleum oil is fractionated by distillation to yield normally gaseous hydrocarbons, hydrocarbons boiling below about 350 DEG F., a virgin heating oil fraction, a gas oil fraction and a residuum fraction. The virgin heating oil fraction is given a preliminary caustic alkali wash and then partially sweetened, for example to a copper number of about 15-30, by treatment with caustic alkali in presence of air.  The gas oil fraction is cracked thermally or catalytically, preferably using a fluidized catalyst, and a heating oil fraction is separated from the cracking products. Before contact with air, this cracked heating oil fraction is washed with caustic alkali and is then blended with the partially sweetened virgin heating oil fraction.  Specification 738,152 is referred to.
Patent GB-118023-A (GB)
IPC: H05B7/12
Abstract: 118,023. Watson & Co., T. H., and Travis, W. Nov. 8, 1917. Furnace details.-Leakage from a hole in a roof or wall through which an electrode passes is prevented by a ring of loose segments pressed towards the electrode by a spring, by gravity, mechanically, or magnetically, and arranged with staggered, lapped, or tongue-and-groove joints. In one form, plates a, Figs. 1 and 3, rest on the machined face of a water-jacket b, and have radial slots a<2> receiving studs c secured in the jacket. 'On these plates rests a second series of plates d breaking joint with the first and having upward flanges d<1> in contact with the electrode and downward outer flanges d<2> resting on the water-jacket. Adjacent edges of these plates are cut away slightly for the passage of the studs c. A third series of plates, or a continuous ring f, is held loosely by the studs c so as to retain the lower rings when the electrode rises. A coil spring e, or an inelastic ring with short springs, surrounds the sets of plates. In another form, a sloping annular seating g, Fig. 5, supports outwardly-tapering segments h each having a lip overhanging the next segment. The weight of the plates is usually sufficient to maintain them in contact with the electrode, but may be assisted by the electro-magnetic action of the current in the electrode.

Abstract: 514,255. Sliding-clasp fasteners. CORNER, G. H. C., and LIGHTNING FASTENERS, Ltd. April 21, 1938, No. 12036. [Class 44] [Also in Group V] For the manufacture of non-metallic sliding- clasp fasteners a strip of integrally connected elements is produced by subjecting a non- metallic material while in the plastic condition to pressure between suitably grooved and shaped surfaces. For instance, a strip extruded from a heated nozzle 5 is passed between rollers 7, 8 provided with shaping members. The shaping members 12, 11 on the roller 7 respectively form the usual interlocking recesses 17 on the fastener elements and grooves 16 which with corresponding grooves formed by the shaping members 13 on the other drum 8 form the slots by which the elements are set on the stringer tape; the usual interlocking projections on the fastener elements are formed by the shaping members 14a on the roller 8. The shaped strip 10 passes to cutting rollers 9 which remove the " flash," at the edges and in the slots and divide the strip centrally to give two strips of connected elements. The shaping members may be mounted on segments so that a damaged segment may be replaced. An epicyclic operation of the rollers may be used. Specifications 391,146, 426,644, 444,405 and 489,176 are referred to. According to the Provisional Specification the rollers may be coated with soap and water to impart a polish to the elements.

Title: Improvements in belt conveyors
IPC: B65G39/16
Filed: 1961-04-05
Abstract: 906,248. Idler rollers for endless conveyers. GOODMAN MANUFACTURING CO. April 5, 1961 [April 5, 1960], No. 12276/61. Class 78 (1). The outer ends of wing rollers of a troughing idler assembly are canted forwardly a predetermined amount in the direction of belt travel at no load but provision is made such that the amount of cant is progressively reduced with progressively increasing load. The arrangement ensures maximum training effect, and insignificant wear due to scuffing between the belt and roller when the belt is unloaded. When the belt is heavily loaded the training effect of the wing rollers is not required, the angle of cant reduces towards zero, and belt wear due to scuffing on canted rollers is not significant. The outer end of each wing roller shaft 20 is connected by a spring steel strip 38 to an ear 36 of a rope clamp 12, the ears slanting rearwardly from the direction of travel 33 of the belt. As the load increases on the belt, the strips 38 twist and the assembly swings forwardly. The amount of troughing thus increases and the angle of cant of the wing rollers decreases. In a modification, Fig. 5 (not shown), coil springs are used in place of the spring strips. The shaft of the centre roller 18 is connected to the wing roller shafts by links 24, 26.

[Class 38 (iv)] Systems depending on two or more machines.-In a starting arrangement for a D.C. rotary transformer of the " metadyne " type in which a regulator machine RG is coupled to the transformer shaft, a relay N1 sensitive to the voltage and speed of the machine RG controls the operation of contactors LS1, LS2 connecting the " metadyne " machine MD to the line. Closure of a switch S, Fig. 2, energizes a relay R1 and operates a switch r1, Fig. 1, connecting the machine RG to the line in series with a resistance X1. When the speed reaches a predetermined value contacts n1 Fig. 2, of relay N1 are closed and energize a relay R2, Fig. 2, whose contacts r2, Fig. 1, short circuit the series resistance X1 and contacts r2<1> insert a resistance X2 in series with the coil N1 contacts on the relay R2 also control the closure of contactors LS1,LS2. Contact r2 is arranged to close before contacts r2<1> open. Should the speed of the machine MD drop relay N1 drops away to disconnect the machine from the line and contacts r2<1> are arranged to open before contacts r2. In a modification, Figs. 3 and 4, closure of a switch S energizes relays R1, R3, Fig. 4, whose contacts r1, r3, Fig. 3, close to connect the machine RG to the line in series with a starting field F2. A shunt field F1 controlled by a resistance X3 is provided and the relay N1 is connected in series with a resistance X4 across the machine RG and field F2. The initial large current in the machine RG operates a relay N2 connected across a series resistance X1 and opens its contacts n2 in the circuit of a relay R2 in parallel with relay windings R1, R3. When the speed reaches a predetermined value relay N1 operates and closes its contact h1 in series with relay R2 and at the same time relay N2 is de-energized by decrease in armature current to close its contacts n2 to energize the relay R2. Contacts r2, r4, r5 are closed, contact r3 is opened and the line switches LS1, LS2 are closed. Contact r2 short circuits the starting resistance X1, contact r3 short circuits all or part of the resistance X3 in the circuit of the field F1, and closure of contact r4 and opening of contact r3 connects the coil N1 in series with F2 which is ineffective and the machine RG is connected in series with a field F3 and a regulating winding RW on the main machine MD across the line. Fall in speed of the machine MD causes release of the relay N1 and return of the circuit arrangements to the starting conditions. Specifications 403,464, 417,517, and 424,082 are referred to.
