Title: Low exotherm curing phenol-resorcinolformaldehyde resins employing alkali metal sulfites and calcium compounds as catalysts
IPC: C08L61/10
Filed: 1968-06-17
Abstract: A fusible, water soluble phenolic resin is made from phenolic material consisting of 50 to 90 mole per cent of phenol and 50-5 mole per cent of resorcinol and 0À55 to 0À75 moles of formaldehyde per mole of phenolic material by (a) reacting the phenol with the formaldehyde at an initial pH of 8À5 to 9À0 in the presence of 0À04 to 0À09 moles of an alkali metal sulphite or bisulphite per mole of formaldehyde, (b) refluxing the reaction mixture to a constant viscosity of 22À7 to 50 poise at 23 C., (c) adding to the reaction mixture the resorcinol and 0À006 to 0À060 moles per mole of formaldehyde of CaO, Ca(OH) 2 , or CaCO 3 and (d) continuing reflux to a constant viscosity of 200 to 400 Gardner seconds. The alkali metal sulphite may be sodium sulphite. An adhesive resin may be prepared by diluting the product to 3À0-4À3 poise viscosity and 40 to 60% solids content, adjusting the pH to 7À5 to 8À9 with aqueous caustic soda and optionally adding a filler. Diluents specified are mixtures of methanol, ethanol, ethyl acetate, ethylene glycol, aviation gasoline and water. The resin may be cured with paraformaldehyde or alpha- or beta-polyoxymethylene prepared by heating paraformaldehyde in the presence of a Lewis acid, e.g. oxalic acid, and colloidal silica. Sufficient curing agent is used that in total 1 to 2 moles of formaldehyde residues are present in the cured resin per mole of phenolic material. In examples the resin is prepared in a vessel fitted with a stirrer and recirculation pump (I), the Ca(OH) 2 is added slurried with water (I) and the fillers are wood flour and walnut shell flour (II). The adhesives are used to laminate Douglas Fir and Southern Pine into plywood.

Patent ES-370121-A1 (ES)
Title: Apparatus for and method of connecting electrical terminals to wire
IPC: H01R43/048
Filed: 1969-07-31
Abstract: In a method of connecting one or more leads to a terminal, a punch 46 and an anvil 48 are moved to cause the anvil to wrap portions of the terminal about the punch to form upstanding ears 12 and the terminal is advanced to position the ears between dies 58, 62 to crimp the ears to the lead or leads. A strip 1 of terminals is located on a guide plate 22 and is advanced step-by-step by means of spring loaded, pivoted feed fingers 32, 34, which have tips 36 engaging in apertures (4) in the strip, Fig. 1 (not shown). The feed fingers are resiliently connected to a piston-rod 28 for reciprocation therewith and drag plates 44 prevent backward movement of the strip 1 as the fingers are withdrawn. The punch 46 and die 58 are driven downwardly by a ram (53), Fig. 4 (not shown), after an operator has placed a bared end of a lead core between the ears 12. The plate 22 is also driven downwardly by the ram against a spring (24), Fig. 6 (not shown), thereby lowering a terminal on to the anvil 48 and shearing another terminal from the carrier strip (3), Fig. 1, between the working edge of a shear blade 66 and the die 62, prior to the crimping action of the dies. As the ram (53) rises, the leading terminal, which has been crimped to the leads is removed from the die 62 by the operator and the terminal strip 1 is advanced to place the leading terminal over the die 62.

Title: Method of producing colored coatings of aluminum
IPC: C25D11/22
Filed: 1969-09-16
Abstract: An anodized aluminium metal or alloy workpiece is coloured e.g. bronze by passing A.C. between it and a counter-electrode whilst immersed in an acidic solution of a Ni or Co salt, in which the pH is maintained between 4À7 and 7 and Al ions are maintained at a value not less than 2 p. p. m. or sufficient to maintain saturation, whichever is the less, to electro-deposit an oxide or hydroxide of Ni or Co.

Filed: 1969-10-20
Abstract: Textile or other material is dried by subjecting it in a vacuum in an enclosed zone to a temperature sufficient to vaporize solvent such as water, perchloroethylene or trichloroethylene in the material. The material is in continuous length form as shown in Fig. 1. The material T passes through an inlet seal formed by rollers 14, through the chamber 12, evacuated by pump 30, and heated by controlled heaters 24, and through an outlet seal 22. Cooling coils 26 condense the solvent which passes to chamber 32. Solvent and chemical such as dyestuff is applied at 18 as the material enters the chamber. The rollers may be outside the chamber, which has a separate inlet seal (141, 161), Fig. 2 (not shown). The material may move over rollers within the chamber, some of which are heated, Fig. 3 (not shown), or may undergo scouring treatment in successive baths (B11, B1, B) before drying takes place, Fig. 4 (not shown).

Title: Locking arrangement for deadbolt latch locks, especially for hotel guest room doors
IPC: E05B65/00
Filed: 1970-03-28
Abstract: An inside turn knob is equipped with an axially movable coupling member spring pressed to position coupling the knob to a deadbolt operating cam. A guest key inserted into an outside tumbler cylinder will press the coupling member to release position so that the key when rotating a latchbolt operating cam and the turn knob will not rotate the deadbolt cam. A manager's key is relatively short and will not depress the coupling member, and therefore can rotate the deadbolt cam along with the latchbolt cam.

Title: Apparatus for transmitting distress signals
IPC: G08B23/00
Filed: 1974-10-22
Abstract: A distress-signal generator aboard a vehicle includes a transmitter with a self-locking relay for energizing a high-frequency oscillator from a local battery in response to one or more trigger signals from respective detectors, specifically an impact detector and a deformation detector. The impact detector comprises two coacting members, one of them fixed to the vehicle body and the other freely movable with reference thereto, the elastically suspended mobile member being generally spool-shaped and having its waist received in an oblong opening of the plate-shaped fixed member. With the major axis of the oblong extending in the direction of vehicle motion, contact between the two members occurs in response to relatively small transverse and vertical accelerations but only with relatively large longitudinal acceleration relative torsion is detected by a horizontal pin on the mobile member bracketed by two stops on the fixed member normally spaced therefrom. The deformation detector includes a bent wire with a rigid but rupturable sheath conforming to the shape of the vehicle body at critical locations. The transmitter comprises a multivibrator tuned to an audio frequency and energized in parallel with the oscillator by the relay, this multivibrator working through an RC circuit into the base of a transistor forming part of the oscillator so as to apply to it a sawtooth signal modulating the generated high-frequency oscillation in both amplitude and frequency, the modulated oscillation being sent out via an antenna coupled with the tank circuit of the oscillator.

Title: TV automatic mains voltage changeover switch - has transistor circuit which detects lower mains voltage and switches in voltage doubler
IPC: H02H11/00
Filed: 1977-01-31
Abstract: The automatic mains voltage supply changeover switch, for television receivers, monitors whether 110V or 220V is present at the supply input. It automatically switches in a voltage doubler if the 110V is detected. The mains input is rectified and applied via a voltage divider (R2,R3) to the base of a transistor (T) and via a resistor (R4) to the gate of a thyristor (TH). If 220V are present, the transistor is on and its collector, coupled to the thyristor gate, prevents the thyristor turning on. The mains input passes through to the output. If 110V are present, the transistor is off and the thyristor is on. The thyristor and a series capacitor (c1) now act as voltage doubler.

Title: Process for electrical discharge machining and its application to the manufacture of dies for the extrusion of metal.
IPC: B21C25/10
Filed: 1979-05-29
Abstract: A process for the spark erosion machining of a workpiece having a cylindrical orifice, formed of any desired cross-section, the invention utilizes an electrode which is moved relative to the workpiece. According to the invention, a first rapid rough shaping pass is performed by descent of the electrode parallel to the generatrices of the orifice. On raising, the electrode is then translated perpendicularly to the generatrices by a distance r and then is lowered at a slower speed and is raised again before performing a circular translation of radius r. The electrode is again lowered and raised, and the operation is repeated n times so as to perform a complete revolution. The present process allows efficient machining of dies for metal extrusion.
