Title: Means for testing an electrical installation
IPC: H04B17/00
Filed: 1952-06-03
Abstract: 699,138. Voltage measurements; testing thermionic valve circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. June 3, 1952 [June 14, 1951], No. 14007/52. Class 37. Measurement of the potential at a number of points 1 ... n in an installation, which points are intended to have nearly the same potential when direct current is passing, is effected by means of a transformer, of which the primary winding 603 is connected in series with a condenser 604 to a two-way switch 605 by which it can be connected either to a source of auxiliary voltage 608 or to one of the points of the installation, and the secondary winding 602 is connected to a voltage-sensitive unit 5. The installation shown comprises a number of triodes, the cathode resistances R1 . . . Rn of which are so chosen that the same cathode potential is obtained for all the triodes at normal cathode currents. The unit 5 comprises a cold cathode valve 500 fed with anode current from a voltage source 510 over a resistance 509 and a relay winding 508. A condenser 511 is connected across the voltage source 510 and resistance 509. Operation of the relay closes the circuit of a bell 513. Bias voltage is supplied from a potentiometer 505 in series with the transformer secondary winding 602. The switch 605 is closed on the contact 606 to charge the condenser 604 to the potential of the source 608. It is then changed over to the contact 607 connected through a switch 73 to one of the cathodes 1 ... n, the potential of which is to be measured. If this potential differs by more than a predetermined amount from that of the source 608 the voltage of the primary winding 603 is changed suddenly and the voltage induced in the secondary winding 602 raises the grid potential of the valve 500 above the ignition voltage so that it strikes and operates the relay 508. The secondary winding 602 may be shunted by a rectifier or a high resistance. A condenser 609 of lower impedance than the condenser 604 prevents operation of the relay by alternating currents.

Abstract: 1,040,453. Electric can openers. BURGESS VIBROCRAFTERS Inc. April 9, 1963 [April 10, 1962], No. 14110/63. Heading B8D. A can opener, mounted on a work surface 50, has an electrically driven traction wheel 8 which may be retracted by manual operation of a handle 17 to enable the rim of a can to be inserted so that, on raising the wheel 8, the top of the can presses up a cutting blade 28 thereby causing the electric motors 4, 5 to be energized. The wheel 8 carried on a shaft 12 is driven from a shaft 10 round which the shaft 12 is caused to rotate in a guide slot 81 when a pivoted lever 18 is moved by means of the handle 17. The blade 28 is secured to a carrier 30 pivoted on a post 32, Fig. 10 (not shown), the carrier also having an aperture through which extends a stud 36 fastened to a switch 23. As the blade carrier 30 is pivoted upwards on raising the wheel 8 under the can rim, the stud 36 is lifted thereby closing contacts 25, 26, Fig. 8 (not shown). The can lid is held by a magnet 40. Being mounted at a given height from the surface 50, the opener is usually operating on cans of predetermined size; for dealing with larger cans, the opener is rotated, Fig. 3 (not shown), to enable a can, held below the level of the surface 50, to be opened.

Title: Controlling the cooling performance of continuous casting moulds
IPC: B22D11/055
Filed: 1974-03-29
Abstract: 1470399 Continuous casting CONCAST AG 29 March 1974 [30 March 1973] 14144/74 Heading B3F [Also in Division G3] A tapered mould for the continuous casting of steel consists of end plates clamped between side plates, the end plates being movable to adjust the angle of the taper to suit the casting rats or casting temperature. In the form of Fig. 2, the end walls 3 each comprise a copper plate 7 on a backing plate 8, and are spaced by gauge rods 20 from a plate 17 hinged at 25. Cooling water chambers in the mould walls are subdivided longitudinally and possibly transversely. The plate 17 can be tilted by a drive mechanism 22 acting on screw 21, to alter the angle of the plate 3. In another form, Fig. 4, the plates 3 are hinged (37) at their lower edges and adjusted by a screw 36 and drive mechanism 35 near the top. An automatic control system is provided to adjust the taper angle during casting if the casting rate or casting temperature changes. In this system the rate of heat extraction by the cooling water in the end walls is compared both with a reference value and with the averaged rate of heat extraction by the side walls. A computer receives the results of these comparisons and may combine them in any desired way to control the drive means for the taper angle setting mechanism. During an adjustment of the angle of the end walls the clamping pressure of the side walls is slackened off to approximately twice the internal ferrostatic thrust.

Abstract: 730,695. Filing papers. MANIFOLDIA, Ltd. May 19, 1954 [May 20, 1953], No. 14227/53. Class 146(1). In or for a filing device in which pockets for the reception of record sheets or cards can be moved in succession upwardly to a viewing station where they are opened and then downwardly to a position where the weight of the pockets tends to keep them closed, a pocket comprises two sides 10, 11 or 17, 18 of sheet material secured or formed integrally along one edge 14 which forms the bottom of the pocket which has an open mouth, at least one side, 11, being formed or provided with stop means adapted to engage the card or cards in the pocket when it is in an inverted position and pressure is applied to the sides 10, 11 to close the mouth of the pocket. As shown in Figs. 2, 3 and 8 each side 11 is creased along a line 12 parallel to the bottom 14 of the pocket to give a permanent set so that the free edge 13 tends to spring away from the other, longer, side 10 and when pressed inwardly, a card or cards is or are gripped between the side 10 and the lower portion 15 of the side 11. To increase the holding grip, a tongue 16 may be cut out as shown in Fig. 3 and set in line with the top portion of side 11. To join the pockets together concertina fashion, a tongue 22 may be cut out of the longer side 10 and each tongue 22 is engaged over the free edge 13 of the next pocket.

Abstract: Polyesters derived from dihydric alcohols and ethylenically unsaturated dicarboxylic acids are stabilized with a soluble non-alkaline amine salt preferably derived from a t-amine and an acid at least as strong as acetic acid but of oxidizing power less than that of sulphuric acid.  The polyesters may be derived from maleic, fumaric, mesaconic, citraconic, ethyl maleic, dimethyl maleic, xeronic and itaconic or 3,6-endomethylene - 1,2,3,6 - tetrahydrophthalic anhydride and various glycols and may be modified with monohydric alcohols, e.g. allyl alcohol, and/or saturated dicarboxylic acids and/or monocarboxylic acids such as linolenic, linoleic, elaeostearic, octadecatrienoic, clupanodonic, acetic and propionic acids.  Specified amine salts are trimethylamine-, triethylamine-, tributylamine-, triamylamine-, tribenzylamine-, dimethylaniline-, N-benzylaniline-, benzyl methylamine-, pyridine-, diethylamine- and a -naphthylamine - hydrohalides, ethylene bis (pyridinium chloride), ethylene bis (dimethyl ammonium bromide) and pyridyl maleate.  An ethylenically unsaturated monomer or syrupy polymer may also be present and p  specified in examples are styrene, diallyl phthalate and methyl methacrylate.  The compositions may be readily cured using peroxide catalysts such as benzoyl, acetyl or lauroyl peroxides and t-butyl or cyclohexyl hydroperoxide, ultra-violet light, or condensation products of aniline or toluidine with formaldehyde, acetaldehyde or butyraldehyde, which products may be used in admixture with a peroxide.  The resins may then be hardened by baking, e.g. at 125 DEG  to 200 DEG  C.  Optional ingredients are conventional inhibitors such as quinone and hydroquinone, fillers such as cellulose fibres, asbestos and glass fibres and plasticizers such as dimethyl phthalate.  The compositions may be used for embedding insects and biological specimens, for castings and for coating or impregnating metal, wood, paper or fabrics of glass fibres or cotton, followed by curing and hardening.
