Title: Improvements in or relating to a gauge for indicating the weight of the liquid contents of a tank
IPC: G01F23/32
Filed: 1949-02-02
Abstract: 661,206. Liquid level pressure gauges. LIQUIDOMETER CORPORATION. Feb. 2, 1949 [July 30, 1948], No. 2850/49. Class 106 (ii). [Also in Group XVIII] In order that a liquid level gauge operating in a tank may be calibrated in units of weight instead of units of volume and remain accurate in its weight calibration during changes of volume with change of temperature, a floatoperated gauge is provided with a temperature responsive element to apply the necessary compensation. The gauge comprises a float 20 secured to the end of a pivoted arm 26, by a bracket 24, which also carries a temperature-operated bellows 76 coupled by means of a link 66 to a rod 62 passing through the hollow interior of the pivoted arm 26. The arm 26 is pivoted at 30 to the lower end of a tubular support 32 extending upwardly to the frame of an indicator (not shown). The indicator is actuated by a vertical rod 34 within the support 32, the lower end of the rod 34 being guided for vertical movement by a pin 36 in the free end of a link 38 pivoted at 40 on the member 32. The pin 36 extends through a curved cam slot 42 in a cam plate 44 pivoted at 46 on the rear of an arm 48 of a bracket 28 which is pivoted at 30 on support 32. The free end of cam 44 is connected by a vertical link 54 to the free end of the horizontal arm of a bell-crank 56 pivoted at 58 on bracket 28. The depending vertical arm of the bell-crank is connected by a pin 60 to the rod 62. When the float arm is level in the position shown and the temperature decreases, the liquid in the tank will contract, reducing its level and lowering the float. The fluid in the bellows 76 also contracts with the temperature decrease, actuating link 66, rod 62, bell-crank 56 and link 54 to move cam 44 upwardly about its pivot 46, causing a slight upward movement of push-rod 34, thus neutralizing the downward movement of the float due to contraction of the liquid in the tank. When the tank is nearly empty the float arm 26 slopes downwardly and no compensation is required for contraction or expansion of the liquid. In this position pivot pin 46 is in line with pin 36 on the lower end of the indicator rod 34 and there is no compensation because the cam will cause no vertical movement of the rod 34. In a modification shown in Fig. 6, compensation is obtained by utilizing the pressure of a gas from a liquid 142 contained in the hollow float 140. The shape of the cam slot 42 may be designed to compensate for irregularly shaped tanks.

Filed: 1941-03-06
Abstract: 546,702. Ventilators. BROAD & CO., Ltd., and RANKIN, A. M. March 6, 1941, Nos. 3075 and 5689. [Class 137] Air is admitted or withdrawn through a cowl or baffle 1 on the outside of the wall 5 of an airraid shelter or other enclosure and is distributed on admission into the interior by a diffuser comprising a frame 22, 23 to the sides and bottom of which is secured expanded metal or wire netting covered with hessian or similar air permeable fabric. The open top of the diffuser is held against the roof of the shelter by wedges 20 inserted under frame members extending through the opening in the walls through which the air passes and supporting the cowl 1. In Fig. 8, a guide member 39 is provided in the cowl and has curved surfaces 42, 43 which merge into a partition 40 which extends through the air diffuser. Air entering the cowl from below passes into the shelter through the part of the diffusers below the partition 40, and the air current through the cowl induces the discharge of air from the space above the partition. To close the ventilator, the hole in the wall 5 is closed by a door 45 hinged to the wall at 46, and bearing against a rubber frame 47, this door normally being flush with the bottom of the diffuser. A flap 44 of the partition 40 is raised when the door 45 is to be closed. An additional roof ventilator such as is shown in Fig. 7 may be used by which air is withdrawn from the shelter when the main ventilator acts only as air supply device. This ventilator may comprise a cowl 31 over a pipe 32 leading to an expanded metal and fabric diffuser of the kind previously described, a plug 35 carried by a plate 36 being pressed into the conical end 34 of the pipe 32 when it is desired to close the opening.

Title: Improvements in signalling systems particularly suitable for hospitals, hotels and the like
IPC: G08B1/08
Filed: 1934-01-30
Abstract: 417,297. Electric signalling systems. SAELEN, E., 30, Skivebakken, Bergen, Norway. Jan. 30, 1934, No. 3157. [Class 40 (i).] In a hospital, hotel or like signalling system in which when a signal is given, local lamps in and outside the originating room light steadily and lamps at a central or service station are flashed, the arrangements are such that a servant in a room may adjust the equipment so that on a call being made elsewhere, the flashing signal is repeated at that room whilst if a call comes from the central station or from the telephone a steady signal is given in that room. An audible signal may also be provided if required. As shown in Fig. 1 the lamps E and F are respectively inside and outside the service station and the lamps G and H1 or H2 are respectively inside and outside the rooms provided with calling equipment. When a call is initiated from point 4 the terminals B, A, C are joined as shown in Fig. 2 so that parallel lamps G and H2 are connected in series with relay R. Lamps G and H2 light steadily and R energizes. Intermittent relay M operates and flashes lamps E and F. The point of origin of the call is marked by lamps H2 and G. Two or more initiating points may be provided in one room, for example in a hospital ward. When the call is answered the signal is extinguished by resetting the switch to normal. If a servant is working in a room the switch is set, by means of a special key, to the position shown in Fig. 3. If now a call is originated the relay M flashes the lamps G and H1 or H2 &c. at the point where the servant is working in parallel with lamps E and F. The point of origin of the call is indicated as before by the steadily burning signal lamps. If it is required to find in which room a servant is working key V is operated to initiate a call and relay N operates and locks up, shorting the contacts of relay M so that the lamps at the room required light steadily. Relay N is unlocked by key U. Contacts I operated by the telephone bell, are connected in parallel with V so that the operation of the bell operates N and lights lamps E, F and the lamps, at a point where a servant is working, steadily as before. An audible alarm S may be provided if required and connected in parallel with G as shown in Fig. 4.
Patent GB-699113-A (GB)
Title: Film-forming, coating, impregnating and like compositions comprising polyvinyl acetate
IPC: D21H19/60
Filed: 1951-02-09
Abstract: Polyvinyl acetate is softened by an ester of a butylene glycol, preferably 1,4-butylene glycol, and a C4-C6 mixture of first runnings fatty acids.  These acids are a mixture of first runnings obtained as a by-product of the oxidation of high molecular weight paraffins. The esters may be mono- or di-esters or both.  They may be made by esterifying the butylene glycol itself or a mono-ether of butylene glycol in the preparation of which an alcohol component containing not more than six carbon atoms has been used.  In the preparation of aqueous emulsions, small quantities of solvents having boiling points above 100 DEG  C., e.g. amyl, hexyl and alkoxy alcohols, may be used. Fillers and pigments, e.g. kaolin, chalk, titanium dioxide and wood flour may be included in the compositions which may be in the form of solutions in, for example, ethyl acetate.  Other plasticizers such as tricresyl phosphate and dibutyl phthalate may be added.  The compositions may be used for film-forming, coating and impregnating and may be applied to textiles and paper or used as floor covering. Specification 663,072 is referred to.

Title: Improvements in or relating to mechanism for the precise and/or rapid adjustment of the position of a movable member of a machine
IPC: B24B47/22
Filed: 1944-02-22
Abstract: 581,486. Grinding &c. machines. VIAL & CO., L. Feb. 22, 1944, No. 3310. Convention date, Jan. 21, 1943. [Class 60] Mechanism for both rapid and precise adjustment of a movable part of a machine, for example, the grinding-wheel carriage 1 of a grinding-machine, comprises a rack 2 on the carriage engaged by a pinion 3 on the axle of a worm-wheel 5, which is engaged by a worm 6 formed on a spindle 7 having slidable and rotatable connection with a toothed wheel 8 and acted on by a compression spring 10. The spring urges the spindle against an abutment 16 on the end of a rod 12 having thereon a fine thread 13 screwing in the frame 14 of the machine, and rotatable by a hand wheel 11, so that rotation of the rod 12 allows, or produces axial movement of the worm 6, which acts as a rack and gives the carriage 1 a fine adjustment. Rapid adjustment of the carriage is effected by rotation of the worm 6, through gearing 8, 21, 20, 19, by a spindle 18 rotatable by a hand wheel 17. In order to eliminate play in the mechanism, the carriage has thereon pistons 24, 25 acted upon by pressure liquid through pipes 26, 27, pressure being maintained on the piston 24 during operation of the machine; by allowing the liquid to act on piston 25, the pressure on piston 24 being removed, the piston 25 effects a rapid withdrawal of the carriage from the operative position. The hydraulic control includes a rotary valve which operates either piston 24 or 25 and simultaneously operates a piston 28 to hold the pinion 8 stationary. In a third position of the valve, pressure on all three pistons is relieved to enable adjustment by means of the hand wheel 17.

Abstract: Styrene or a ring-substituted derivative thereof and an organic peroxide polymerization catalyst are added in small increments to a drying or semi-drying oil fatty acid or tall oil fatty acid or lower alkyl ester thereof at 130-215 DEG  C. and the mixture is heated until reaction is complete, whereupon the epoxy reaction product of a polyhydric phenol with an epi- or di-halohydrin is added and reaction is continued until esterification is substantially complete. Suitable substituted styrenes are the o-methyl, m-ethyl, p-propyl, 2,4-dimethyl, 2,5-diethyl, 3,5-dibutyl, o-, m- or p-chloro, 2,4-dichloro or 2,5-dichloro derivatives.  Catalysts mentioned are 2,2 - bis - (tert. - butylperoxy)-butane; tert.-butyl hydroperoxide; di-tert.-butyl peroxide; tert.-butyl propyl peracids; tert.-butylpentamethylethyl peroxide; cumene hydroperoxide.  The first stage of the process may be carried out in an organo solvent, e.g. xylol, Varsol, Solvesso (Registered Trade Mark), Solvasol, kerosene, toluol, high-flash naphtha, heavy aromatic naphtha. Suitable polyhydric phenols for the epoxy resins are resorcinol, 2,2-diparahydroxyphenylpropane, p,p1-dihydroxybenzophenone, p,p1 - dihydroxydiphenyl, p,p1-dihydroxyldibenzyl, and o,o1,p,p1-tetrahydroxydiphenyldimethyl methane.  When using a lower alkyl ester of the fatty acid, or transesterification catalyst, e.g. lithage, sodium methoxide, sodium hydroxide is preferably employed. The products are useful for coating-especially for cap closures.  The compositions may include a pigment, e.g. TiO2 and a dryer, e.g. cobalt naphthenate.  In examples, epoxy resins from epichlorhydric and 2,2-diparahydroxyphenylpropane are esterified with copolymers prepared with cumene hydroperoxide from:-Examples 1, 2, 3, 6 and 7, styrene and a cottonseed oil acid fraction prepared with cumene hydroperoxide.  Example 4, styrene and tall oil fatty acids, and Example 5, styrene and linseed oil fatty acids.  In each case the product was cut with a heavy aromatic naphtha Amsco F-80 to yield a coating composition.

Abstract: 719,801. Jet propulsion engines; gas turbine plant. LUCAS (INDUSTRIES), Ltd., J. Jan. 22. 1953 [Feb. 13, 1952], No. 3788/52. Class 110(3) [Also in Groups XI and XXXV] A gas turbine or jet propulsion engine fuel system comprising a fuel pump which delivers fuel to the burners through a main path and a by-pass path arranged in parallel with a portion of the main path, a volume control in the main path and means responsive to a pressure difference in the main path for controlling the flow in the by-pass path has a connection between the by-pass path and the sump or inlet of the pump and electromagnetic means responsive to a temperature of the engine for actuating two valves one of which closes the by-pass path and the other diverts fuel from the main path to the sump or inlet of the pump. A variable delivery pump a supplies fuel to the burners b of a gas turbine c through a main path d. The fuel flow in the path d is controlled by means e which acts on a servo-mechanism f which regulates the output of the pump a. The means e may be operated manually or by automatic means responsive to such factors as the speed of the gas turbine, atmospheric pressure or the air pressure supplied by a blower. A by-pass path h connects the discharge of the pump a to the outlet of the control means e. The flow through this by-pass is controlled by a closure member n mounted on a flexible diaphragm m, the movements of which are controlled by the pressure drop across a restriction g in the main path. An electromagnetically operated valve p is arranged in the by-pass path h and a similar valve q controls the flow into the passage r leading to a sump or the inlet side of the pump a. The electromagnet s for operating the valve p has a pair of opposed windings v, w and the electromagnet t has a single winding x. The windings w, x are connected in series and are energized by electronic or other apparatus u controlled by a thermocouple y in the jet pipe, combustion chamber or other part of the gas turbine c. When the engine is started, the winding v is energized and the valve p opened. Fuel then flows through the main and by-pass paths to the engine. When the temperature in the vicinity of the thermocouple exceeds a predetermined amount the electromagnet v is neutralized by the electromagnet w and the valve p closed by the spring 2. Should the temperature continue to increase, the valve q is opened and fuel is diverted from the main path through the by-pass paths to the sump or inlet of the pump. The valves p and q may, if desired, be actuated simultaneously.
