Title: Improvements in or relating to electric switches having overload release devices
IPC: H01H71/74
Filed: 1948-01-29
Abstract: 643,187. Automatic circuit - breakers. GENERAL ELECTRIC CO., Ltd., and RIDGE, F. Jan. 29, 1948, No. 2728. [Class 38(v)] An electric circuit-breaker has a thermally operated tripping arrangement in which, in order to permit ready adjustment of the value of overload at which tripping is affected, bimetallic strips are mounted on member which may be pivoted under the control of a rotatable cam carried by the member. The bimetallic strips B.M.S. are mounted at one end on an insulating supporting spindle 14 pivoted in brackets 15. Fixed to the spindle 14 is a bracket 16 carrying an eccentric disc or cam 17 which bears against a fixed part 18 of the main switch moulding 7, so that rotation of the cam 17 turns the spindle 14 through a small angle to move the free ends of the strips B.M.S. towards or away from a trip bar 21. The cam 17 has a serrated surface engaged by a spring detent 19. The trip bar 21 is supported by cranked side pieces 20 pivoted to the brackets 15 and one of the pieces 20 has an extension 23, which has a stepped tongue 24 normally holding tripping contacts T.C. closed. Screws 22 in the trip bar 21 are set so that they just touch the strips B.M.S. when the cam 17 is in its zero position and the cam 17 is then rotated to obtain the correct overload setting by moving the strips away from the screws 22. When an overload occurs the trip contacts T.C. are opened to de-energize an electromagnet holding the circuit-breaker contacts closed.

Abstract: 1488405 Spray-producers; mixing GUSMER CORP 23 Jan 1975 [23 Jan 1974] 3071/75 Headings BIC and B2F Apparatus for mixing and ejecting two liquids, comprises a mixing chamber 37, a plunger 15 including a threaded metal rod 49 and an elastomeric sleeve 51 surrounding the metal rod to eject completely mixed liquids from the chamber through outlet 39 in nozzle 67 after use, inlets 41 and 43 for introducing the liquids into the chamber through slots 59 and 63 respectively which are axially offset to promote whirling and mixing of the liquids, and a partitioning, sealing member 45 which has an inwardly projecting annular shoulder 47 having a sealing fit with plunger 15 so that the liquids are held separately when the plunger is in the position shown and are able to mix when the plunger is withdrawn. The apparatus is included in a pistol arrangement, Fig. 1 (not shown), which pneumatically controls plunger 15 by means of a piston attached thereto and reciprocating in a cylinder with a compression spring on one side and compressed air on the other so that on actuating an inlet valve the compressed air forces the piston back, withdrawing the plunger from the mixing chamber to allow the liquids to mix and leave the chamber and on releasing the valve, the spring forces the piston and plunger back, thus ejecting remaining mixed liquid from the chamber. An auxiliary compressed air supply cleans the nozzle.

As shown, a reversible electric motor 7, Fig. 1, drives two shafts 31, 33 by means of a differential gear having an outer wheel 17 reely rotatable on bearings 19 and provided with planet wheels 25 meshing with sun wheels 27 and 29 carried by shafts 21 and 23 respectively. The shafts 21, 23 carry bevel pinions 35, 37 meshing with bevel pinions 36 and 38 respectively. The shafts 31, 33 carry brake drums 55, 57 coupled to the shafts 31, 33 by one-way clutches so that only the cylinder from which the wrapper is being unwound is braked. The brake drum 57, Fig. 3, is freely rotatable on the shaft 33, but is engaged by brake linings 59 on members 61 and 63 adjustable by a screw 65. A driving member 67 secured to the shaft 33 and disposed within the drum 57 carries pins 71 and has an hexagonal facing 69, while rollers 73 are disposed between the facing 69 and drum 57. When the member 67 is rotated counterclockwise the drum 57 is not driven, but if rotated clockwise the rollers 73 tend to drive the drum 57. In operation, both brakes are applied to the required degree by adjustment of the screws 65. The motor 7, Fig. 1, is then started in the appropriate direction to drive both cylinders 1, 3. Fabric fed to the winding cylinder is interwound with the wrapper and the desired treatment, e.g. steaming, is applied. The motor 7 is then reversed to unwind the treated fabric from one cylinder and simultaneously to wind a length of fabric to be treated on to the other cylinder. An I-shaped rubber sealing ring 81, Fig. 2 (not shown), with a garter spring is provided around the cylinder trunnions. Specification 738,028, [Group IV (c)], is referred to.

Title: Improvements relating to polyester resins
IPC: H01B3/42
Filed: 1960-01-29
Abstract: A coating composition, for insulating electrical conductors, comprises an aqueous dispersion of a certain polyester resin, a curing agent for the resin and a surfactant.  The polyester is a condensation product of a lower dialkyl ester of terephthalic and/or isophthalic acid, ethylene glycol and a saturated aliphatic polyhydric alcohol having at least three hydroxyl groups, e.g. glycerol (see Specification 775,081).  Before the resin is dispersed in water, it is finely pulverized, e.g. in a ball mill or by causing particles of the resin to collide at high velocity. The curing agent may be triethanolamine titanate, titanium lactate, octylene glycol titanate, tetracresyl titanate or tetraphenyl titanate.  The surfactant may be glyceryl monooleate, stearic acid, or esters of stearic acid with glycerine, ethylene glycol or polyethylene glycol. If the pH of the dispersion is not of itself from 6,0-7,5 it may be adjusted to be within this range by the addition of acetic acid pyromellitic acid, methyl morpholine or ammonia.  The dispersion may also contain a thickening agent, e.g. hydroxyethyl cellulose.

Filed: 1927-02-05
Abstract: 265,612. Telefunken Ges. fiir Drahtlose Telegraphie. Feb. 6, 1926, [Convention date]. Thermionic amplifiers and generators. -Valve transmitters of the self-excited or externally-excited types have the output circuit so arranged that the highfrequency current between the plate and filament passes only through the condenser of the tuned oscillatory circuit whilst the direct current passes through the coil of that circuit. The tuned circuit comprises series condensers a, b and a tapped coil e. One side of the tuned circuit is connected directly to the plate of the valve H, and the other side is connected through a condenser c to the valve grid. This condenser may be set to neutralize the inter-electrode capacity when using external excitation, or may be set out of balance for selfexcitation. The high-tension source f is connected between the filament and a point 'between the two condensers a, b, and the direct-current circuit to the plate is completed by a highfrequency choke coil r and a part of the coil e. The absence of a high-frequency connection between the coil and the earthed filament avoids the formation of subsidiary circuits comprising the coil sections and their capacities to earth. Condensers d selected by switches may be connected across the whole coil e for tuning. An additional coil may also if desired be connected in parallel with the coil e.
