Abstract: 949,223. Change-speed control. HUMBER Ltd., and H. W. THORNLEY. Dec. 11, 1961 [Sept. 13, 1960], No. 31553/60. Heading F2D. In a column-mounted gearshift mechanism in which a rotatable and slidable rod 11 is operated by a manual gear lever 14, the rod carries coiled compression springs 22, 28, the former being effective when the rod is raised to engage first or second gear and the latter when the rod is lowered to engage reverse. The lower spring 22 is mounted between a radial abutment pin 24 on the rod and a stop member 20 carried by the steering column 10, while the upper spring 28 is mounted between a second radial pin 29 on the rod and a washer 32 which, in the neutral position, engages a third pin 30 on the rod and, by the action of spring 22, bears against stop member 20. To engage first or second gear a light force is necessary to raise rod 11 against spring 22, the pin 30 and washer 32 separating from stop 20 so that spring 28 is carried bodily with rod 11, Fig. 3, while for reverse rod 11 is lowered so that pin 30 separates from washer 32 and spring 28 is compressed between pin 29 and stop 20, Fig. 4. Rotation of rod 11 is transmitted to the gear-box 17 by a linkage 16, and longitudinal movement by a Bowden cable 18. The upper end of spring 22 has a radial portion 26 engaging column 10 to place the spring under torsion to take up clearance.

Abstract: 1430821 Variable-speed gear FICHTEL & SACHS AG 3 July 1973 [4 July 1972] 31665/73 Heading F2D In a two-speed bicycle hub comprising a fixed sun-wheel 6, planetary wheels 10 mounted on a carrier 4, 4a driven by a sprocket 25, an internally toothed ring gear 5, and a drive bushing 12 which has a splined connection 40 with the planet carrier and provides a bearing for an extension 18 of the ring gear, high-speed drive being effected from the gear 5 through pawls 34 to a ring 19 having a drive connection 23, 22 with the hub sleeve, and direct drive taking place, on retraction of the pawls 34, through the bushing 12, a back-pedal braking cone 33, and pawls 35 coacting with the hub sleeve, displacement of the ring gear away from the member 4 is prevented by the ring 19 which has an abutment 21 with the interior of the hub sleeve. Corresponding displacement of the bushing 12 is prevented by a spring ring 16 housed in a groove in the bushing and abutting a surface of the ring gear. Alternatively, the displacement of the bushing 12 may be prevented by a tubular or spring spacer between the end of the bushing and the bearing cone 3, and in this case the abutment 21 and the spring ring 16 may be dispensed with. Retraction of the pawls 34 for direct drive is effected by backpedalling causing reverse movement of the pawls relatively to a sleeve 13 having an internal cam formation. The spindle 1 has a series of circumferential grooves 24 separated by ridges 25 of which that at one end provides an abutment for the integral sun wheel and cone 2 which is screwed on to the spindle, torque reaction on the sun wheel being resisted by grooves 15 engaging the bicycle frame 14. Braking torque is transferred to the frame by a lever 30.

Title: Longrange headlamp
IPC: F21V5/00
Filed: 1973-07-03
Abstract: 1439011 Vehicle headlamps CIBIE PROJECTEURS 3 July 1973 [5 July 1972] 31739/73 Heading F4R A vehicle headlamp comprises a parabolic reflector, a bulb having a cylindrical filament centred on the reflector axis on either side of the focus, and a lens 10 which has at least one refractory surface 28 which lies on the surface of a cone whose axis coincides with the reflector axis, thus forming with the other side of the lens a curved prism which deflects the reflected light rays to give a non-circular shape to the isocandelas of the lamp beam. The angle which the part-conical refracting surface makes with the other side of the lens is sufficiently small to ensure that the light rays are deflected by the surface 28 less than an amount which would diminish the illumination intensity along the reflector axis. This is illustrated by Fig. 5 in which the surface 28 deflects a notional illumination area ABCD to A<SP>1</SP>B<SP>1</SP>C<SP>1</SP>D<SP>1</SP>, the deflection not being so great as to reduce the light passing through the axis at O. the illumination at O thus remaining constant. In the example shown, the part-conical surfaces 28 are grouped in four sectors 16, 18, 20, 22 which give respective light beam deflection of 4 degrees 30 minutes in the directions of the arrows d to flatten the equal illumination curves into atrapezoidal shape, Fig. 6 (not shown). The groups of protrusions 28, which may be formed integrally with the remainder of the lens or separately adhered thereto, are separated from one another by a relative narrow horizontal non-deflecting strip 24 and by a relatively wide vertical diffusion strip 26. By suitable arrangement of the protrusions 28 equal illumination curves of other, e.g. rectangular, shape may be produced.

Abstract: 662,636. Self-contained systems. MORRISON, A. C. Nov. 19, 1948, No. 32037/47. Class 38 (iv). To prevent overloading of the generator of a selfcontained system comprising prime-mover, generator and consumer, such as is described in Specification 604,899, a switch 8 normally closed by a spring 10 and shortcircuiting a variable part of a resistance 16 in the shunt field circuit of a machine 13 (which may be the generator of the system, or, in the case of an A.C. system, the exciter for the alternator) driven by the prime-mover, is opened by a governor 2 to reduce the voltage of the machine when the speed of the prime-mover falls to a predetermined value. The governor may also control the fuel supply to the primemover. The remainder of resistance 16 may form part of an automatic voltage regulator for the machine. The inherent hunting of the system upon overload may be utilized to signal this condition and the speed of hunting may be slowed down by fitting the switch with a dashpot. Instead of directly acting upon the resistance 16, the switch 8 may control that resistance through a relay.

Abstract: 488,280. Filter-presses. MANOR ENGINEERING CO., Ltd., and MALKIN, E. W. Nov. 30, 1937, No.-32868/36. [Class 46] In a filter-press, for filtering and drying clay or other material, of the type comprising single filter plates which are hollow or formed with interior passages for heating medium, whereby with the aid of vacuum the pressed cakes of material are dried, the vacuum is also applied to the liquid material, during filtering, by way of ports connecting the filtering chambers to a. filtrate outlet leading to a sealed vacuum chamber of relatively large capacity which is interposed between the vacuum unit and the filtrate outlet. Fig. 1 shows the arrangement of the filter-press, Figs. 4 and 6 show alternate filter plates, and Figs. 2 and 3 are sections taken, respectively, on planes indicated by line 2-2, Fig. 4, and line 3-3, Fig. 6. Filter plates a alternated with frames b are hollow to receive steam which can enter by inlet d, from a pipe e, being discharged through outlet f to a pipe g. The liquid clay or other material enters the press by a central opening c, being fed by an air compressor m through a sealed pressure chamber n and through a feed pipe o. A vacuum unit p is connected to the filtrate outlet k through a sealed chamber q and a pipe r. The unit p de-aerates the clay or other material during filtering, and also acts in conjunction with steam in the plates a, to dry the filtered material. Drying may be partly effected with the aid of compressed air supplied to the filter-press from the compressor m by way of pipe v, and hence by different paths under the control of valves. The air may be passed through pipes v, v<1> and central feed opening c to the filtered material, and be discharged to pipe r through ports l and outlet k, and through ports z and outlet w. Alternatively, the air may be passed through pipes v, t and ports x to the filtered material and be discharged, as before, through ports z and outlet w. The outlet w branches into the pipe r. As a further alternative, the air may be admitted through pipes v, u and ports y to opposite sides of each cake of filtered material, and be discharged through both outlets k, w. In the method employing compressed air for drying purposes, the clay or other material is first filtered, pressed, and de-aerated, then partly dried by means of compressed air, and finally completely dried by the combined action of steam and vacuum. Specification 307,525, [Class 46],. is referred to.

Abstract: 1484565 Insolubilized biologically active materials KOCH-LIGHT LABORATORIES Ltd 13 July 1973 [13 July 1972] 32911/72 Heading C3H [Also in Division C2] A biologically active material comprises a water-insoluble solid on to at least part of whose surface has been adsorbed diazotized mdiaminobenzene, biologically active macromolecules having been covalently bonded to the diazotized m-diaminobenzene. The macromolecules may be proteins, e.g. enzymes or coenzymes, e.g. glucosidase, dextranase, α-amylase, catalase, glucose oxidase, thermolysin, N- acetyl amino acid amidohydrolase, peroxidase, chymotrypsin, uricase and/or papain and may specifically be glucose isomerase, isoamylase, pullulanase, urease, pronase, lactate dehydrogenase and/or cholin esterase. Any residual diazo groups may be deactivated, e.g. by reacting with a phenol such as #-naphthol. The waterinsoluble solid may be a porous molecular sieve or may take the form of a bead, tube, sheet filter or membrane. When it is a membrane the biologically active macro-molecules may be attached to one or both faces or different biologically active molecules may be attached to opposite faces of the membrane. Other preferred substrates include diatomaceous earth, silica, sand, glass, polysaccharide, polyacrylamide, polyamide, polycarbonate, polyester, polyurethane, titanium oxide, zirconium oxide, aluminium oxide and/or iron oxide. Preferred such substrates are silica, nylon, natural or regenerated cellulose, carboxymethyl or diethylaminoethyl cellulose, cross-linked dextran, cellulose acetate, porous glass, porous silica or balsa wood. The material may be made by adsorbing diazotized m-diaminobenzene on to at least part of the surface of the water-insoluble solid substrate and covalently bonding the biologically active macromolecules to the diazotized m-diaminobenzene. The m-diaminobenzene may be diazotized in presence of the substrate or before being adsorbed thereon. The biologically active material may be reactivated after it has become biologically inactive by adsorbing additional m-diaminobenzene on the surface of the solid substrate and then covalently binding fresh biologically active macro-molecules, or by treating the material with sodium dithionite to remove the biologically active macro-molecules to regenerate amine groups, optionally adsorbing m-diaminobenzene molecules on the solid substrate, diazotizing the amine groups and covalently bonding fresh biologically active macromolecular to the diazotized amine groups.
