Filed: 1966-07-25
Abstract: 1,157,928. Valves. DOLE VALVE CO. 25 July, 1966, No. 33412/66. Headings F2V. A thermostat valve for an engine cooling system comprises a dished plate 11 having a mounting flange 15 and fastened to a stirrup 12 and a guide sleeve 26. The latter guides a thermal power unit 20 when the unit moves relative to its piston, the free end of which is secured to the stirrup. Initial movement of the power unit against spring 46 unseats a portion 24 thereof constituting a secondary closure member from a port 29a in a main closure member 28 to permit flow to the engine radiator via ports 36 in the main closure member. Further movement of the power unit causes arms 44 of spring seat 45 to abut edges 48 of slots in a guide sleeve 38 secured to the main closure member. The perimeter of the main closure member is thus unseated, in response to this further movement, from the passage 16 of plate 11 to permit additional flow to the radiator. This parallel arrangement prevents hunting and the initial opening of valve 24, 29a provides an effective flushing flow to remove foreign bodies. In alternative embodiments, the loading spring seats directly against part 22 of unit 20 and a collar on stem 13 actuates the main closure member. A separate secondary closure member may be mounted on the power unit.

Title: Improvements in and relating to piezoelectric gauges and a method of their manufacture
IPC: G01L23/28
Filed: 1960-09-30
Abstract: 966,542. Piezoelectric gauges. H. LIST. Sept. 30, 1960 [Oct. 2, 1959], No. 33622/60. Heading G1N. [Also in Division H1] In a piezoelectric gauge of the type used for measuring the pressure in the cylinders of internal-combustion engines comprising a casing and a sleeve attached thereto enclosing the piezo elements, the annular gap between the elements and the sleeve is filled with a highly insulating solid or liquid polymer. In Fig. 1 two quartz crystals 4 and 5 sense pressure communicated through a transfer head 6 and develop charges at electrodes 7 and 8 which are taken off via lead 12 and the casing, a layer 10 of soft metal such as aluminium providing a low-resistance contact. Coolant flows through channels 18 into an annular chamber 13 around the crystals, which are fitted in a sleeve 3 but insulated therefrom by an annular gap 19 filled with an insulating polymer. The latter may be solid, such as poly-tetrafluorethylene, but is preferably liquid so that it can also be used as the coolant. In the latter case the sleeve is perforated at 20 with axially extending slots staggered in a circumferential direction of the sleeve (Fig. 2, not shown). A silicone oil is suitable as coolant and insulant. If a solid polymer is used, this may be formed in situ by pouring in a liquid precursor, with or without a catalyst, and allowing to stand or heating to 100C. until converted into solid form.

Abstract: 628,488. Pre-stressed reinforcements, and structures. SMEDEGAARD, E. J. Nov. 19, 1946, No. 34274. Convention date. Jan. 22. Addition to 599,774. [Class 20(iv)] A modification of the reinforced concrete structure according to the parent Specification comprises reinforcement members consisting of thin flexible concrete bars having a tensioned steel reinforcement which bars do not contain more concrete than is necessary to take the compressive stresses created by the tensioned steel reinforcement characterised in that the bars are provided with lateral projections or flanges to support secondary elements such as hollow bricks or slabs. The bars reinforce the structure but during erection serve as supporting elements, and the structure is erected without shuttering. The bars may be of inverted T-section, and, e.g. in the erection of floors, supported at the ends on walls, and if necessary braced at intervals along their length. Filler blocks &c. are then supported on the flanges of the bars so that the lower surface is flush and the concrete structure cast, e.g. over and/ or between the blocks. The pre-stressed reinforcement may be situated slightly below the centre of gravity of the bar, which may have the additional reinforcement in the upper side. The Specification as open to inspection under Sect. 91 comprises also two Figs. illustrating floor constructions, e.g. Fig. 1 (Cancelled) shows filler blocks 9 recessed at 10 and supported on the flanges 7, 8 of the concrete bars 5 with stretched cores 6, concrete 11 being cast between the blocks. This subject-matter does not appear in the Specification as accepted.

Filed: 1938-11-25
Abstract: 521,807. Protective cut-out arrangements. REYROLLE & CO., Ltd., A., and TIPLADY, J. Nov. 25, 1938, No. 34330. [Class 38 (v)] In control systems in which apparatus; such as mining machinery J, is controlled from a remote supply switch A<3> over a trailing cable B incorporating a two-conductor pilot circuit (such as conductor B' and the cable-sheath used also for earthing the apparatus), the contactor-coil A<4> maintaining the switch A' closed is controlled by the normally-closed contacts of a protective relay G and contacts of a pilot relay F which are closed when the pilot circuit is sound and energized from transformer E<1>. The relay coils are shunted by condensers which absorb inductive surges that may cause sparks and hence explosions. When the apparatus switch K is moved to the "start" position, the pilot circuit is made at contacts K', K<3>, so closing the switch A' and energizing the coil J<4> in the power-conductor, whereupon the switch K is moved to " run position in which K<1> is earthed through K<2> and contacts of J<4>, and F is energized by unidirectional current passed by the rectifiers G<3>, J<5>. If a fault to earth occurs in the pilot circuit so that J<5> is short-circuited, unidirectional current flows through the protective relay and series rectifier G<2>, so causing the main switch to open or, if already open, preventing its closure. The relay G has a low current-setting so as to respond to faults of high resistance. The relay F is de-energized by an open pilot circuit or resistance-increase therein, and by supply-voltage failure, the relay being of low resistance so as to respond to even a slight resistance-change. The pilot circuit can also be opened by earth-leakage or overload in the main line itself, and has an emergency " stop switch. The coil J<4> prevents automatic restarting if a momentary interruption in the supply occurs. For control of the apparatus J from the supply end, the link H<3> is moved to the dotted position shown and " start " switch H closed, the latter being then shunted by a back contact H<2> of the supply switch. The Specification also includes systems in which the main switch is manually closed through tripfree mechanism and retained by a latch controlled by no-volt coil in series with the relay contacts, Fig. 5 (not shown), and modifications of these arrangements in which the pilot relay is shunted by a rectifier of the same sense as that G<2>, and the relay G opens the pilot circuit instead of the trip circuit or contactorcoil circuit, Figs. 6, 7 (not shown).
