Abstract: 1,176,101. Snap-action electric switches. TATEISI ELECTRONICS CO. 1 Jan., 1968 [14 Jan., 1967], No. 79/68. Heading H1N. In a push-button snap-action switch the contact arm 5, 8, Fig. 1, is pivoted at B to an intermediate actuating lever arm 3 to extend between fixed contacts 6, 7, and has a bent spring portion 5A beyond which the arm is in engagement with a rigid pivoted arm 9. On depression of push-button 4 the bent portion 5A extends to snap the system over centre point D and to act as a retractive spring by moment about pivot point A of the arm 3. Both pivot points A and D are arranged on a common terminal 2. The arm 9 is slotted at 10, Fig. 3, for location on edge 12 of a central slot 11 of the contact arm 5 through which the arm 9 passes. The arrangement results in a positive sliding action of the moving contact 8 before the contacts open.

Title: Manufacture of hollow silicate sphere
Inventor: TERASE KUNIHIKO
IPC: B01J13/02
Filed: 1982-01-05
Abstract: PURPOSE:To obtain fine hollow silicate spheres having a uniform grain size and high compressive strength by forming fine liq. droplets contg. silicate and a compressive strength increaser, allowing the droplets to gel in an expandable state, and expanding and vitrifying the gelled spheres. CONSTITUTION:Silicate and a compressive strength increaser are agitated in a liq. medium contg. a surfactant to form fine liq. droplets contg. the silicate and the increaser. The droplets are allowed to gel in an expandable state, and the gelled fine spheres are expanded at a high temp. and vitrified. It is especially preferable to use a mixture of sorbitan fatty acid ester with polyoxyethylene sorbitan fatty acid monoester as the surfactant because a stable emulsion is obtd. An org. liq. medium such as benzene, toluene, xylene, kerosene, trichloroethylene or perchloroethylene or a mixture thereof is used as the liq. medium.

Inventor: FINNERUP OLE
IPC: E05B65/46
Filed: 1993-04-14
Abstract: A drawer locking system which allows only one drawer No. 2 and 3 to be opened at a time.  The system means that when one drawer No. 2 is pulled out, it is no longer possible to pull another drawer No. 3 out. The system operates in that a rocker arm No. 7, which is fixed to a cabinet No. 5 engages in a locking plate No. 4, which is fixed to a drawer No. 2 and 3.  When a second drawer No. 2 with locking plate is pulled out, the rocker arm No. 7 will lock for other drawers No. 3. The design of the system is such that it permits large tolerances and a short assembly time. Finally the system provides the facility for central locking of the drawers. <IMAGE>

Title: Improvements in and relating to preparations of fatty acid esters
IPC: C11C3/04
Filed: 1951-01-04
Abstract: Fatty acid esters having one or more free hydroxyl groups are made by the re-esterification of a triglyceride with a polyhydric alcohol and a saturated free fatty acid at an elevated temperature, preferably between 160 DEG  and 180 DEG  C. and with the exclusion of atmospheric oxygen.  By exclusion of atmospheric oxygen is meant that the reaction is effected under reduced pressure, e.g. at 2-40 mms., and/or in an inert gas atmosphere. An alcoholysis catalyst such as a metallic oxide, e.g. an alkaline earth oxide, is preferably present. A particularly preferred reaction temperature is that of the boiling point of the alcohol. Zinc, aluminium or titanium oxides are specified catalysts. Starting materials preferably have low iodine values.  In an example, hydrogenated whale oil is treated at 160-180 DEG  C. and at 10 mms. with stearic acid and glycerol in the presence of zinc oxide to give a product which on removal of volatiles by means of a carrier gas, yields a water-in-oil or oil-in-water emulsion. The products may be used to make emulsions in the food-stuff and pharmaceutical industries optionally with additions such as phosphatides, natural animal and vegetable fats, lipoids and hydrocarbons.

Title: A device for use in ascertaining the mean specific gravity of liquid in a tank or reservoir
IPC: G01N9/14
Filed: 1935-01-05
Abstract: 442,182. Sampling liquids. IONIDES, M. G., The Old Vicarage, Markyate, Bedfordshire. Jan. 5, 1935, Nos. 398 and 25786. [Class 106 (v)] [See also Group XX] An apparatus for measuring the mean specific-gravity of a body of liquid comprises a vessel containing a hydrometer readable through a transparent wall, the vessel being adapted to be lowered into the body of liquid and having means for allowing the liquid to enter the vessel, the entry being determined by the pressure of surrounding liquid, and means for retaining a portion of the liquid as the vessel is removed. The vessel comprises a glass cylinder A closed at its ends by metal caps B, C, held apart by bars D, the whole being surrounded by a metal casing J fitted with a transparent portion J<1> and a cover K rotatable over that portion. A wire framework E supported within the tube A to guide the hydrometer F, carries projections E<1> to prevent damage of the hydrometer and also rings E<4> fitted with a tube E<5> to carry a thermometer E<6>.The lower end C of the cylinder contains an aperture C<1> fitted with an automatic non-return valve C<2>, and the upper end B carries a manually operated valve H fitted to a tube H<1> which extends down inside the tube A. With valve H closed the vessel is lowered by handle G into the body of liquid, and the liquid enters through valve C<2>. On raising the vessel the liquid is retained and if sufficient has entered to float the hydrometer F a reading is taken. If insufficient liquid has entered, the compressed air is allowed to escape by opening valve H, and more liquid is trapped by again lowering the vessel into the liquid. If too much liquid enters, then on opening valve H liquid will be forced out of tube H<1> until the level falls to the bottom of the tube, this level being chosen so that the hydrometer floats at this depth over its whole range. Alternatively, the liquid may be allowed to enter by the pipe valve H on lowering into the liquid. The valve H may be fitted with a remote control so that it may be operated at various depths and samples taken in at those depths.

Patent GB-986935-A (GB)
Title: Production of lithium borate
Inventor: ARCHAMBAULT MAURICE
IPC: C01B35/10
Filed: 1962-01-05
Abstract: Lithium borate is produced by reacting calcined lithium-bearing silicates with an aqueous solution of borax in a pressure vessel at 175-275 DEG  C. for 10 minutes 2 hours.  The resultant slurry is then discharged from the vessel and filtered.  The filter cake is leached with water, preferably near boiling water, and the washings combined with the filtration mother liquor.  The resultant solution is then fractionally crystallized to yield lithium borate, any remaining unreacted borax being recycled to the first stage.  The strength of the borax solution is between 5 and 20% by weight and an amount, such that an excess of 10-80% of borax over that required to react with all the lithium, is employed.  The lithium-bearing minerals that may be used after calcination are spodumene, petalite, eucryptite and lepidolite.

Abstract: 637,571. Making electric cables. COMPAGNIE GENERALE D'ELECTRICITE. Jan. 7, 1946, No. 588. Convention date, July 21, 1944. [Classes 83 (ii) and 83 (iv)] [Also in Group XXXVI] Power hammers.-In the manufacture of electric conductors formed of a number of wires, the wires are compacted to form a conductor of definite shape by being moved longitudinally between radially moving dies mounted in a member rotating about the conductor and within a ring of fixed rollers which actuate the radially moving dies. Fig. 1 shows apparatus for compacting a stranded conductor of circular cross section. The cable is slowly moved longitudinally between two dies 5 which are subjected to the action of oppositely disposed hammers 4. The dies and the hammers are mounted in a member 3 which is rotated within a fixed outer ring having projections in the form of rollers 2 which act on the outer ends of the hammers to effect a rapid hammering of the dies. The dies may be built up of more than two sections and may be shaped internally according to the cross section of the conductor. In the form shown in Fig. 5, a segmental cable is compacted by being passed through the space 9 of a three-part die or former 10 which is compressed by a two-part rotary die 6 and hammers 4. Three conductors of segmental shape can be compacted simultaneously by using a mandrel 11 as shown in Fig. 6. Hollow cables may be formed by compressing around a mandrel 12 alternate hard wires 14, for example steel, and soft wires 13 such as aluminium, the soft wires being pressed round the surface of the harder wires as shown on the left-hand side of Fig. 7.
