Abstract: 1,244,914. Self-steering axles. B. CESCHI. 17 Jan., 1969 [19 Jan., 1968], No. 2822/69. Heading B7H. A self-steering axle for a lorry, van, articulated vehicle or trailer comprises steel axles 5 which each have associated therewith means defining king-pin axes disposed both forwardly and rearwardly of the stub axles, and means for fixing the position of the forward or rearward axes as the vehicle is driven forwardly or rearwardly respectively so that wheels on the stub axles will self-steer about the appropriate axes as the vehicle turns. The stub axles 5 are carried by respective end links 4, each connected by pivot pins 10 to a pair of bars 8, 9 which are connected by a common pivot pin 7 to the respective forked end 6 of an axle beam 1 for mounting transversely of the vehicle. Projecting portions 8c, 9c of the bars 8, 9 are connected by pivot means 11 to respective transverse link rods 2, 3. Locking means 12, 13 are provided for preventing movement of either the rod 2 or the rod 3 relative to the beam 1 so that the position of either the foremost or rearmost pair of pivot pins 10 is fixed to define king-pin axes about which the end links 4 can swivel. In order that the free ends of the end links 4 and the associated ends of the corresponding arms 8 or 9 connected thereto may move along different arcs centred on the fixed pivot pins 10 and the pivot pins 7 respectively, each pivot pin 10 has two eccentrically disposed portions, one of which can rotate in the end link 4 and the other in the associated bar 8 or 9. Actuation of the locking means 12, 13 may be controlled manually or may be effected automatically upon selection of forward or reverse gear. The axle may be converted to power operation by providing hydraulic or pneumatic power means which turns the stub axles about the pivot pins appropriate to the direction of travel in dependence on rotation of the steering wheel of the vehicle or on relative rotation of the sections of an articulated vehicle.

Title: Improvements in Railway Signalling.
IPC: B61L1/18
Filed: 1916-02-26
Abstract: 102,087. Sykes Interlocking Signal Co., W. R., and Tarrant, R. W. Feb, 26, 1916. Electro-magnetic switches.-An electro-magnetic relay used in railway signalling has a neutralizing winding, wound in opposition to the main coil of the relay, and energized when the armature reaches its normal attracted position, thus reducing the tendency of the core to become permanently magnetized, and preventing sticking of the armature. The two windings e, f are connected in parallel across the track rails a, b, the circuit of the neutralizing winding f including contacts h 17, which are closed only when the armature g is attracted. When a train arrives on the section, it short-circuits the coils e, f, and the armature falls away, a contact j opening a circuit and operating the signal k. When the train leaves the section, the coil e only is energized and the armature is attracted with full force. Upon the closure of the contacts h, 17, the winding f is energized and diminishes the magnetization, which however is still sufficient to prevent accidental displacement of the armature.

Title: Improvements in or relating to devices for planing helical teeth on bevel gear wheels
IPC: B23F5/12
Filed: 1934-01-29
Abstract: 415,645. Gear cutting. BRANDENBERGER, H., 43, Hadlaubstrasse, Zurich, Switzerland. Jan. 29, 1934, No. 3010. [Class 83 (iii).] In planing helical bevel gears by the process wherein the blank is rotated continuously while the tool is reciprocated to and from the pitch cone apex, the tool speed is varied during the stroke so that it is maintained substantially proportional to the circumferential speed, diminishing towards the pitch cone apex, of the blank at the point of operation. By this means the clearance angle C, A, B, Fig. 1, between the tool and the work is maintained approximately constant, while the working range C, E, Fig. 3, of the tool may constitute a large proportion of its total movement A, B. In Fig. 1, the line a represents the developed path of a tool of cutting angle D, A, C on the blank pitch cone. Since the line C, A remains at a fixed angle to the tool path S, S1, the variations of clearance angle will be the same as the variations of the angle B, A, S 1 which is tan u/v where u is the circumferential speed of point A and v is the instantaneous speed of the tool at point A. In order to reduce these variations to a minimum, a crank drive for the tool may be arranged as shown in Fig. 3, wherein the ordinates C, C1 of the curve represent the instantaneous tool speeds and lines, such as C2, C, or E2, E, indicate the circumferential speed of the blank at different points. In another modification, the crank centre M may be arranged on the opposite side of the tool path from the pitch cone apex S, but in this case the crank shaft speed must be varied by means of eccentric wheels &c. In another modification, Fig. 4, the slide S carrying the tools may be reciprocated by a crank pin K working in a curved guide having its centre at Z, this arrangement giving speed variations similar to those shown in Fig. 3. In another modification, the tools may be reciprocated by means of cams. In a machine embodiment, Fig. 6, the tool head 16 is mounted in a casing 1 and a central shaft, driven by worm gearing from a pulley 3 carries a crank pin 7 engaging a block moving in a guide slot 9a of the cross head 9. The latter is connected to inclined rams 10, 101 provided with carriers 11, 11<1> for the tool holders 13, 131.

Title: Plansifters
IPC: B07B4/08
Filed: 1977-01-26
Abstract: The flat sifter serves for separating granular particles into different fractions by screening and for eliminating constituents of lower specific gravity, such as clays or dust, by means of controlled airflows. The object is to overcome the disadvantages of the grit-cleaning machine, such as large dimensions, a high energy consumption and a complicated construction, and to utilise the advantages of the flat sifter, such as a compact design and a low energy consumption. The screening stack (2) performs the functions of classifying and cleaning. Classifying takes place in the known screening frames having an inserted screen. Cleaning is carried out in special cleaning boxes (1, 3) before and after classifying. Air flows through the cleaning boxes in such a way that it is possible to suck off the parts of lower specific gravity. Adaptation to different operating conditions is possible by means of various throttling members (5, 10). Sectors of use are corn milling, the food industry and the chemical industry. <IMAGE>

Abstract: 103,376. Fiske, W. G. March 2, 1916. Pulp, preparation of.-In disintegrating waste paper, wood pulp, &c, a mixture of the material with water or other liquid, adapted to promote disintegration and to extract any substance it is desired to remove, is delivered by a pipe 15 to one or more channels 25 in a drum 11, which is mounted on rollers 17, 18 and rotated by a worm 22 engaging a circumferential ring 23. The channels 25 are formed by one or more helical flanges 24 and are provided with cross-gates in the form of baffles, barriers, or strainers of the form shown. These impede the flow of the material through the drum and cause a tumbling movement. Those inclined to the axis of the drum in the direction shown, and reaching to the top of the flanges, put back any lumps of material into a previous convolution and so tend to detain masses of material in the apparatus until thoroughly disintegrated. The gates may be straight or curved, as shown in Fig. 5, and may be of different depths. Water may be supplied within the drum by a pipe 44. The pitch and depth of the helical flange or flanges 24 may be varied. Tho material delivered at the flared end 11, may be screened to effect final separation of lumps, which may be returned automatically to the shoot 16. According to the Provisional Specification, rearwardly inclined deflectors may be mounted within the drum clear of the helical flange, to prevent material from falling into a convolution of the helical flange in advance of that from which it has fallen.
