Abstract: 1,124,187. Direction indicator switches. ESSEX WIRE CORP. 27 July, 1966 [11 Oct., 1965], No. 33732/66. Heading G4Q. [Also in Division H1] A direction indicator switch for a road vehicle provided with two latched " on " positions is also provided with intermediate " on " positions where the switch remains on only while held; the latter positions are used when overtaking since the steering wheel is not then moved sufficiently to operate a return mechanism. In the neutral position latch posts 32 and 32a depending from the movable part (27) of the switch engage in detents 13 and 13a formed in flexible ribs of the fixed part of the switch. When the switch is moved to an unlatched operative position, (Fig. 6, not shown), the latch posts ride up the sides of the detents, but the latter still exert a restoring force. In this position depending stop posts 45 and 45a engage stop blocks 23 and 25 mounted on resilient arms, and their resistance indicates the operative position. Further pressure on the operating lever overcomes this resistance and the posts 32 and 32a move over the humps into the latched position. In this position one of two resilient return fingers (30, Fig. 1, not shown) projects into the path of a cam (2) on the steering column (1) to provide an automatic return mechanism. The switch comprises two conductive members 35 and 37 connected to switch terminals (not shown). In the neutral position, the arms of member 37 rest on raised platforms 42, and member 35 is connected to contacts 19 and 19a thereby connecting both the rear signal lamps to a brake-operated switch. In the operated position, member 35 is connected to only one of the two contacts 19 or 19a; the other contact is connected to member 37 which also engages one of the two contacts 18 or 18a to connect front and rear signal lamps on the same side of the vehicle to a flasher unit.

A liquid or other fluid heater comprises at least four hollow heat exchange elements joined as by bolting, clamping or welding, along their longitudinal sides to form a central passage, the elements forming around the passage a duct or group of ducts carrying a fluid to be heated, the element walls carrying fins extending into said duct or ducts. The central passage contains a burner, and the hot burner gases H heat the elements directly by radiation and are then either passed directly to a chimney or alternatively passed over the outside of the elements or through the flue tubes extending therethrough before passing to waste. The heat transfer walls of the elements may be coated with ceramic or other corrosion resisting material. They may also be corrugated. Figure 1 shows a four-sided element, a plurality of which form on assembly a unit shaped as in Fig. 3. The wall 8 of each element is of heat insulating material and contains ports 3 to permit entry or discharge of the heat receiving fluid. This fluid may be discharged from the element through a finned tube 47 extending therethrough (Fig. 14, not shown). Flue tubes 44 may extend through the elements, Fig. 12 (not shown). The elements may be formed by arcuate members secured to one or both sides of a cylindrical wall (Fig. 9, not shown). Figs. 16 and 17 (not shown) are alternative forms of apparatus in which two separate fluid streams P, S are heated. The stream S receives heat from the heated fluid P.

Convention date, June 16. [Class 106 (ii)] [See also Group VIII] A method of testing the quality of yarn fed intermittently to a machine consists in temporarily imposing an additional twist to it, so as to present to the measuring instrument a distortion-resisting length of yarn of substantially circular cross-section. The invention is described in connection with a knitting machine but is applicable to other machines wherein the feed of yarn or cordage is intermittent. A bracket 14, adjustable on a standard 10 carries two upstanding members 17, 18 a length of yarn lying between which is clamped. After being twisted by rotation of the clamp on the member 18 the yarn is gauged between these points, untwisted and released for utilization in the machine. The member 18 functions as a bearing for the twisting head 28 and also as a backing member for a rack 19 operated from the " 104 gear " shaft 52. The rack acts upon a pinion 30 fixed to the head 28 to rotate it and the clamp 20<1>, 211. There is a similar but non-rotary clamp 20, 21 on the member 17. A rod 33 controlled by cams on the shaft 52 and carrying a cross-head 36 keeps the pivoted portions 21, 21<1> of the clamps open while yarn is passing. A similar rod 40 lowers, at controlled intervals, a measuring plunger 41 on to the yarn, which is supported during measurement.

Title: Silica-alumina cracking catalyst and method
IPC: C10G11/04
Filed: 1955-12-05
Abstract: A catalyst of the silica/alumina type used for cracking hydrocarbons, consists of a coprecipitated silica-alumina which is dispersed while in a hydrous state in a matrix consisting predominantly of silica, the final catalyst after drying and calcining containing 5 to 20 per cent of alumina.  In examples, an acidified aqueous solution of aluminium sulphate or nitrate is mixed with water glass solution to produce a gel containing 20 to 60 per cent of alumina.  The hydrous gel is finely divided, e.g. in a colloid mill and is suspended in an aqueous solution of sodium silicate and allowed to set to a heterogeneous gel.  The components are mixed in the proportions required for the final alumina content.  Alternatively, the silica gel may be formed separately and mixed as a hydrous gel with the silica-alumina gel. The gel complex may also contain up to 10 per cent but preferably below 5 per cent of zirconia. thoria, magnesia, or beryllia.  The composite gel is then washed, freed from sodium ions, e.g. by washing with ammonia or aluminium salt solution, dried and calcined at 1200 DEG  F.  The catalyst may be formed into beads before drying and calcining, by dropping globules of the final alumina-silica hetero-gel into oil.  Alternatively beads may be made by spray-drying the gel.
