Title: Improvements in or relating to synthetic linear polymer compositions
IPC: C08L77/00
Filed: 1956-01-20
Abstract: The durability of synthetic linear condensation polymers to light is improved by incorporation with them of a small quantity of manganous compound having a reducing anion, i.e. an anion having a standard electrode potential (referred to the hydrogen electrode at 25 DEG C.) exceeding 0.1n volts, where n is the number of electrons liberated by oxidation of the anion.  The condensation polymer may be a polyamide (including polycaproamide), polyester, polyesteramide or polyurethane.  The manganous compound may be the hypophosphite, sulphite, sulphide, selenide or oxalate.  Incorporation may be effected (a) by addition of the manganous compound to the polymer-forming mixture; (b) by addition of the manganous compound in admixture with or coated on pigment to be slurried with the polymer; or (c) by impregnation of the pre-formed textile material.  In examples: (1) and (2) manganous oxalate or manganous hypophosphite is added to an evaporator containing nylon 66 salt and aqueous acetic acid and nylon polymer is made therefrom in conventional manner, titanium dioxide being added in aqueous slurry during the autoclave cycle; (3) ester-interchange is effected between dimethyl terephthalate and ethylene glycol in presence of lead oxide and manganous sulphite and the product is polycondensed to produce polyethylene terephthalate.  Specification 3725/42 (as open to inspection under Sect. 91) is referred to and the invention of Specification 753,880 is disclaimed.

Abstract: 995,074. Control of D.C. motors; snapaction switches; retractive switches. DAIMLER-BENZ A.G. Jan. 16, 1964 [Jan. 19, 1963], No. 2075/64. Headings H2B and H2J. A windscreen wiper for vehicles is driven by a two-speed compound motor which cannot be switched-on immediately when its shunt field winding is ineffective, rapid change from the " off " position, through the low-speed, to the high-speed setting being prevented. Main switch I operates a relay for energizing the motor, and is actuated against the force of return spring 3, carrying auxiliary switch II with it, thereby closing this switch and ensuring that the shunt field winding is in circuit in advance of energization of the motor. When the main switch is released, slider 7 is freed so that the switch II can be opened independently to remove a short-circuit from a resistor in series with the shunt field winding of the motor. The motor has a brake-winding for returning the wiper blades to a horizontal position when the drive is disconnected. The switches I, II are disposed on lever arm 1 in the region of the steering wheel, the lever being used for other control purposes. In another arrangement, the auxiliary switch is actuated by a rockable angle lever with snap-over action, one lever arm acting as a switch-operating cam, and the other lever arm projecting through a slot in handle 2 and serving for selective manual operation of the switch II, Figs. 3, 4 (not shown).

Abstract: 448,280. Supply systems for discharge lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., Caxton House, Tothill Street, Westminster, and ALDINGTON, J. N., c/o Siemens Electric Lamps & Supplies, Ltd., Dock Road, Preston, Lancashire. Jan. 22, 1935, No. 2115. [Class 38 (iv)] Emergency systems.-Upon extinction of discharge in a high pressure hot cathode discharge lamp an auxiliary source of light not subject to delay in starting is connected, for a predetermined period, to the supply mains by thermally responsive means. The auxiliary source is switched out when the temperature (and hence the vapour pressure) of the discharge lamp falls to a value such that re-ignition can take place. The discharge lamp 1 having starting electrodes 4, 5 may be connected in series with an incandescent lamp 7, 8 whose filament is tapped and brought to the stationary contact 11 of a thermal switch 10, 11 which is operated by a coil 9 carrying the discharge current and is arranged to short circuit a part 7, of the lamp filament when the tube 1 is functioning normally. A further contact 12 co-operating with the movable contact 10 is of itself operated by the heat of the discharge tube 1 so that when the discharge ceases contact 10 leaves contact 11 and engages contact 12, to short circuit the lamp 1 and connect the lamp 7, 8 across the mains. When lamp 1 has cooled sufficiently to permit re-ignition contacts 10, 12 open in re-insert the lamp I in series with the lamp 7, 8. In a modification the lamp 1 is shunted by an incandescent lamp through two thermal switches in series. One of these switches is opened by the current of the discharge and the other is closed by the heat of the lamp 2f. After the tube has been operating normally it is extinguished, both switches are closed until the lamp 1 has cooled sufficiently to permit re-ignition. During normal operation when one of the switches is closed by the heat of the lamp 1 the other is maintained open by the discharge current. Specification 447,428 is referred to.

Abstract: 1,083,511. Processing histological tissues. TECHNICON CO. Inc. Jan. 18, 1966 [Feb. 3, 1965; May 14, 1965], No. 2220/66. Heading G2J. An apparatus for processing histological tissue microscopic examination comprises (Fig. 2) a plurality of receptacles 46 arranged in a circle, each receptacle containing a processing liquid maintained at a controlled temperature by an associated liquid bath 18 containing a heater 274, a thermostat 278 and a stirrer 262. The tissue is carried in a perforated container 166 supported on a tube 184 which is held in an aperture in a dome shaped top 154. The container 166 is fitted with a cover 168 which seals the receptacle 46 in which the container is disposed, so that a partial vacuum may be applied by a vacuum pump 238 attached to a conduit 235 via a tube 100 and a conduit 218. The container 166 is intermittantly moved from one receptacle 46 to an adjacent receptacle by a motor 418 Fig. 5 (not shown) which causes a roller 228 to raise the top 154 and hence the container 166; the top is held in this position by a roller 231 which supports a cam follower on a tube 92 which is attached to the top 154 and is concentric with tubes 90 and 100. The tube 90 which is coupled with tube 92 is then rotated by an intermittantly driven member 232 to move the container 166 over the next receptacle 46, and the roller 231 is withdrawn thus lowering the container 166 into this receptacle. The container 166 is oscillated up and down in its receptacle 46 by the rotation of a cam 234 which engages the cam follower 230 causing the tube 92 to oscillate; the amplitude of the oscillations is small and is absorbed by a helical spring 206 to prevent the vacuum seal being broken. A solenoid 248 is provided which causes the receptacle 46 to be opened to the atmosphere just before the container is removed from the receptacle. The sequence and timing of the operation of the apparatus is controlled by a program control Fig. 5 (not shown). Details of processing conditions using the apparatus are given.
