Title: Liquid level sensor
IPC: G01F23/74
Filed: 1977-01-13
Abstract: 1527193 Liquid level indication BW CONTROLS Inc 13 Jan 1977 01339/77 Headings G1H and G1N A liquid level sensor comprises a float 34 moving up and down on a guide tube 32, a magnetic proximity switch 68 e.g. a reed switch in the tube, magnetic means 80 for closing the switch and maintaining it closed when the float passes the switch moving in one direction and means for opening the switch when the float passes the switch moving in the opposite direction. This arrangement avoids problems due to power failure and of redundancy which occur with latching relays necessary if the switch does not remain closed. Reed switches are latched by small bias magnets (88), Fig. 2 (not shown) or the reeds have a high residual magnetism and the float provides leading and trailing fields of opposite direction. A number of switches which may be normally on or off are arranged in the tube. Various arrangements of magnets are described.

Title: Production of propane derivatives
Inventor: BEWLEY THOMAS
IPC: C07C43/12
Filed: 1954-01-16
Abstract: 1 : 1 : 3 - Tributoxy - 2 - halopropane is obtained by the action of hypohalous acid on acrolein to give a -halo-b -hydroxypropionaldehyde, which is steam-distilled to form a -haloacrolein, followed by treating this product with a acrolein, followed by treating this product with a primary or secondary butanol in presence of an acid catalyst, the former used also as a water-entrainer.  Examples of the process using hypochlorous acid and normal and isobutanol are given and the products, mainly 1 : 1 : 3-tributoxy-2-chloropropanes, contain some 1 : 1-and 1 : 2-dibutoxy-2-chloro-prop-2-ene.  The 1 : 1 : 3 - tributoxy - 2 - halopropanes may be dehydrohalogenated to 1 : 1 : 3-tributoxyprop2-enes.  These react with amidine compounds to give 2-substituted pyrimidines, e.g. with guanidine to give 2-aminopyrimidine.

Abstract: 474,061. Converting. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 16, 1936, No. 1442. Void. Convention date, Jan. 17, 1935. [Class 38 (ii)] A converting arrangement in which additional discharge devices are connected in parallel with the normal devices. The Figure shows the invention applied to a parallel type inverter. Additional valves 22, 23 are connected directly in parallel with the valves 13,14. During normal operation only the valves 13, 14 operate, but if overload occurs or one or both of the valves 13, 14 fail, the valves 22, 23 come into operation. Safeguard against breakdown is thus ensured and a higher overload capacity produced. Specification 219,026, [Class 38 (ii)], is referred to.

Title: Improvements connected with the shuttle-operating mechanism of looms
IPC: D03D49/46
Filed: 1925-04-25
Abstract: 249,455. Lucas-Lamborn Loom Corporation, and Lucas, J. April 25, 1925. Picking-motions; shuttles.-The shuttle 33d is handed across the shed by means of two shuttle carriers 151, which receive and support the shuttle alternately, the shuttle being transferred from one carrier to the other at the middle of the shed by means of latching devices. The shuttle is provided with grooves 156, 156<a> for engagement by supporting-fingers 154, 154a, which are provided in pairs, on the carriers, the fingers on one carrier being out of alignment with those on the other carrier. The fingers and grooves may be tapered. Spring-controlled hooked members 157, 157<a> on the respective carriers co-operate with lugs 161, 161<a> on the shuttle to latch the shuttle to one carrier or the other. As these approach one another, the latch that is not engaged by the shuttle engages the other latch and disengages it from the shuttle whilst itself engaging the shuttle, which is thus transferred from one carrier to the other. The carriers are provided with guards or shields 170, 170a to enclose the fingers and prevent entanglement therewith of broken warp threads. These guards have tapered ends 169, 169a and sloping parts which move aside sagging warp threads when the carriers travel into the shed, whilst bevelled or curved portions 153 on the carriers exert a similar action when the carriers travel from the shed. The guards are offset with respect to one another and the fingers may be rivetted to them. The thread from the bobbin 37a in the shuttle is tensioned by being passed under the angle 167 of a U-shaped wire 166 pivoted to the shuttle. Specification 233,687 is referred to.

Abstract: 310,307. Fitzgerald, J. M. Jan., 23, 1928. Walls.-Reinforced-concrete cribbing for wall foundations consists of courses of headers 10 and stretchers 13 forming vertical walls. Each header is substantially rectangular in section, and is formed at one or both ends with T-shaped ends 11, which extend below the bottom surface of the header, and thus form spacers 12. The stretchers are similar, but the ends are formed as kerfs 14 for receiving the parts 11. Some of the stretchers are larger than others, as shown, to enable break-joint constructions to be formed. Spacers 15 are formed on the kerfs 14, and spacers 16 may be formed between them. The undersides of the stretchers are formed with tapering curtains 17, forming at their lower edges relatively narrow openings 19. These parts are proportioned so that the angle of repose of the material filling the cribbing, as indicated by the line 21, Fig. 6, touches the edges 22, 23. The curtains 17 may, however, be set on the inner sides of the cribbing, and may be set on the upper faces of the stretchers.

Abstract: 690,587. Manure distributers. MASSEY-HARRIS, Ltd. Jan. 30, 1952 [Jan. 31, 1951], No. 2381/51. Class 6(i) [Also in Group XXIV] Relates to apron-chain feeds for vehicular manure spreaders of the type described for example in Specification 680,558 in which the apron-feed is driven intermittently from the road wheels over the floor of the vehicle to transport the manure to the rear for distribution by rotary spreaders. According to the invention, the apron sprockets a<SP>1</SP> are driven through a friction roller B<SP>4</SP> actuated by pivoted drive-plates. B<SP>1</SP> to rotate a wheel B<SP>3</SP> on the sprocket shaft B, motion being imparted to the drive-plates by a cam C rotated by the ground wheels. As shown, the endless apron-chain A, passing over. front and rear sprockets a<SP>1</SP>, is driven by the plates B<SP>1</SP> rocked to and fro on the sprocket shaft B by a telescopic rod D<SP>1</SP>, D<SP>3</SP> pivoted to one end of a lever D pivoted at x and carrying a roller d engaging a lobed cam C driven from the ground wheels. The friction drive is effected by the roller B<SP>4</SP> guided in a tangential slot b<SP>2</SP> in the driveplate and pressed inwardly by an incline b<SP>1</SP>. The wheel B<SP>3</SP> is retained, on reversal of the drive-plate under the action of spring A<SP>2</SP>, by a second friction roller B<SP>5</SP> and incline a<SP>1</SP> on the frame member A<SP>1</SP>.

The stop e on rod E is set for maximum stroke against a sleeve d<SP>3</SP> carrying the pivot x of lever D. The rod E can then be moved to disengage roller d from cam C to put the apron out of operation. The play between stops e; e' prevents jamming.
