Title: Process for making refractory linings
IPC: C04B35/14
Filed: 1974-02-14
Abstract: 1434662 Moulding linings in receptacles J E GARREAU and G H GARREAU 14 Feb 1974 [2 March 1973] 6719/74 Heading B5A [Also in Division F4] A refractory lining 6 for a receptacle such as a casting ladle, crucible or electric furnace 1 is made by placing a former 8 therein and supplying the space therebetween with a quartzitebased material containing 0À5-1À5% by weight of at least one thermosetting agent, compacting the material and preheating it after compaction at a temperature between 100-280‹ C., removing the former and heating the material to bake it. The agent may be a phenol-formaldehyde resin and the material may contain 0À1-2% by weight of a fluxing agent for silica. The furnace shown includes a metallic jacket 1 with a safety lining 3 and induction coils 14. Material is fed from a spout 4 to form a lining base compacted by vibration; the former 8 composed of separable parts 8a, 8b, 8c is placed on the base and further material supplied to form the wall which is vibrated by means 11. The thermosetting agent provides a binder for the quartzite during the preheating and allows the former to be dismantled; at higher temperatures the fluxing agent acts as binder. An external lining may, alternatively, be provided on a receptacle by placing a former around the outside of the receptacle.

Title: Safety belt retractor
IPC: B64D25/06
Filed: 1974-02-14
Abstract: 1460801 Inertia safety belt R C FISHER 14 Feb 1974 [3 Aug 1973] 6741/74 Heading A3V In an inertia safety-belt retractor a bell rolls up a conical seat 62 and pushes a plunger 48 to actuate a pawl and a ratchet detent, the spherical apex of the conical seat having a larger radius of curvature than the ball so that only point contact is made between the ball and the seat. It is stated that this improves the sensitivity of the device and reduces noise. The axis of the cone (X-X) is offset at an angle to the rest of the device so that the device may be mounted at an angle while keeping the axis X-X vertical. The pawl mechanism has two detents, one for each flange of the spool with one detent (Fig. 5, not shown) offset behind the other to engage its ratchet later than the other. This is said to avoid "bounce" on engagement of the pawl.

Abstract: 271,592. British Thomson-Houston Co., Ltd., and Young, A. P. March 15, 1926. Magneto-electric machines.-A magneto for producing multi-point ignition in each cylinder of an internal-combustion engine comprises a number of stationary coils with associated distributing means, and a continuous ring magnet rotor. Fig. 2 shows a construction adapted to give two-point ignition in a three cylinder engine. The rotor 5 has six poles and the armature two coils 6, and the distributer 7 which is mounted on the rotor shaft has six terminals. In this arrangement, the contact breaker has a three point cam, but by employing a six point cam, two-point ignition in a six cylinder engine may be obtained. To protect the magnet poles against demagnetization, thearmature cores have extensions 9 surrounding the rotor. In Fig. 3, a modified distributer for twopoint two cylinder ignition comprises two slip-rings 19, 20 upon which bear brushes 17, 18 connected to the secondary windings of the coils 15, 16. The rings carry contact arms 21, 22 which cooperate with electrodes 23, 24 connected to the sparking plugs 25, 26. The Specification describes a twelve cylinder twelve-point magneto having an internal rotor, and a six cylinder sixpoint magneto having an external rotor. Where three or more ignition points per cylinder are required, the distributer preferably is provided with a corresponding number of slip-rings. Such a distributer, similar to that shown in Fig. 3, isdescribed for three cylinder three-point ignition. Specifications 138,081 and 214,682 are referred to.

Title: Improvements in weft detecting mechanism for looms for weaving
IPC: D03D51/34
Filed: 1923-03-13
Abstract: 211,019. Hollingworth, E., (Crompton & Knowles Loom Works). March 13, 1923. Welt-feeler arrangements.-A box-like rectan. gular slide 34, Figs. 1 and 4, movable in a casing 30 is formed with several toothed weft-engaging surfaces 35, 36, 37, between which two or more sets of weft-engaging teeth 41, 42, Fig. 3, on a member 39, Figs. 1 and 3, are movable, these teeth preferably having bevelled sides so as to prevent shearing action with the fixed members 35, 36, 37. The member 39 is pivoted on an eccentric stud or screw 40 in the slide 34 and has an arm 46 engaged by a hook 44 and lug 45 on a rod 43 having a doubledover end engaging a horizontal lever 47 pivoted on a stud or screw 48 on the slide 34. A spring-controlled arm 51 on a stud 52 engages the lever 47 whereby the slide 34 and the detecting-members are moved to the position shown in Figs. 1 and 8, a stop-screw 49 on the rod 43 engaging the casing. When the detectors are engaged by a weft carrier having a sufficient supply of weft thereon, swinging movement of the detector 39 is prevented and the slide is moved directly back, but if the weft is substantially exhausted, the detector swings on its pivot, as shown in Fig. 11, whereby a relative movement between the rod 43 and the slide results, and the spring-controlled arm 51 moves the lever 47 about its pivot 48, so that this lever acts on a projecting portion 27, Fig. 10, of a forked arm 26, thereby turning a shaft 25 carrying an arm 24 connected to a controlling member or rod 23. This member then moves into the path of an actuator and weft-replenishment is caused, the member remaining in operative position until the next beat-up, at which time a filled weft carrier engages the weft detectors and moves the slide forwards, whereby the parts are returnd to normal position. The detecting surface 36 may beformed as a separate plate 36<a> positioned between the surfaces 35, 37 by spacing-blocks 38.

The bell crank 11 has an outwardly extending arm and the crank 12 an inwarding extending one. The other arms 16, 17 of the cranks 11, 12 are inwardly projecting and connected by a track rod 18. The crank 11 is connected by a drag link 19 to the drop arm 20 of a steering box. The track may be varied by moving the bearings 3, and 4 inwardly or outwardly by equal amounts as shown in dotted lines locking bolts (not shown) being provided for locking the bearings on the transverse members 5, 6 in the desired position. In a modification the connecting rods 9, 10 are connected to two upstanding or depending levers mounted on a transverse rockable cross-shaft at or near the ends thereof. The cross-shaft may be connected to the steering wheel of the vehicle through a steering box or the shaft may be formed as an extension of the driven shaft of the steering box. In order to impart greater angular motion to the inner wheel in a turn the two levers may be angularly off-set.
