Title: Improvements in or relating to Phase Switching Circuit Arrangements
IPC: H03H7/18
Filed: 1968-02-13
Abstract: 1,165,314. Phase-shifting circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 13 Feb., 1968 [2 March, 1967], No. 6914/68. Heading H2F. [Also in Division H4] A phase-switching circuit arrangement which may be used in a PAL colour TV receiver for repetitively switching the phase of a reference carrier through 90 degrees, comprises a resistance 2 in series with an impedance 3 of the same value, means such as the transformer 1 for applying the signal to be phase-switched across the series circuit, a load 4 connected to the junction of the impedances, and switching means adapted alternately to connect the two ends of the series circuit to a point of reference potential. In Fig. 3 the switching means comprises a pair of diodes 6, 7 which are rendered conductive alternately by square wave signals applied to terminals 10 and 11. When diode 6 conducts the output is the voltage across resistance 2, and when diode 7 conducts the output is the voltage across impedance 3. The phase rotation is independent of the output load and the output voltage is the same in both switching positions. A modified circuit uses a centre-tapped transformer, Fig. 3 (not shown).

Title: Improvements relating to the manufacture of lipsticks and the like
IPC: A61K8/42
Filed: 1951-03-22
Abstract: A lipstick or other cosmetic composition of essentially oily, fatty or waxy character contains a water soluble dye, particularly an eosin in free acid or salt form, and an acyl alkanolamine of formula <FORM:0719300/VI/1> where R is an alkyl radicle containing 4-17 carbon atoms, and R1 is hydrogen, or alkyl containing not more than four carbon atoms.  The A and B carbon atoms may be substituted by one or two alkyl groups, the total number of carbon atoms in such a group, or in both groups together not exceeding two.  R may be straight or branched, and may contain rings; hydroxyl or halogen may be present.  The R.CO-group is normally derived from natural or synthetic fatty acids, e.g. oleic, stearic, lauric, ricinoleic. Reference is made to mono- and di-ethanolamides and isopropanolamides of teaseed-oil, olive oil, castor oil and cottonseed oil fatty acids. Unsaturated alkanolamides are preferably made from the natural oils rather than from the fatty acids.  The alkanolamides should be washed with brine above their melting point and dried at 110-150 DEG C prior to use.  From 5 per cent up to 80 per cent of the alkanolamides may be present in the cosmetic composition.  The dye should be first dissolved in the amide, and then added to the other ingredients. Examples disclose compositions containing lanoline, cocoa butter, beeswax, ozokerite, carnauba wax, glyceryl mono-oleate, olive oil fatty acid ethanolamide, mineral oil, perfume, insoluble lake, and tetrabromofluorescein or its sodium salt.

Title: Rapid switching circuit for high voltages
IPC: H04N9/27
Filed: 1974-02-19
Abstract: 1449384 Voltage switching circuits for capacitive loads; cathode ray tube circuits COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 19 Feb 1974 [20 Feb 1973] 7606/74 Headings H3T and H4T A circuit for rapidly switching the voltage across a capacitive load, e.g. the screen voltage at a penetration type cathode ray colour tube, includes means for providing the new voltage and means for speeding the charge to the new value comprising a plurality a resonant circuits which are selectively connected to the load for two successive half cycle periods, the first to resontly charge the voltage and the second to resonantly restore the voltage. As shown, operation of switch 26 to select a desired screen voltage for tube 11 causes an amplifier 25, 24, 23 to change the charge on the screen capacitance until the voltage fed back by potentiometer 27 equals the reference voltage provided by the switch. The change of charge is speeded by selecting one of a number of resonant circuits having precharged capacitors 33, 43, 53. AssQming the screen has a reference one of the desired voltages, the operation of the switch 26 also operates a corresponding one of contacts 32, 42, 52 to cause a rapid exchange of charge between the capacitor and the capacitance 12 of the screen so that the screen voltage rapidly reaches a level at which it is sustained by the amplifier 23-35. At the end of the half cycle the switch goes off. When the next voltage is selected by a switch the same resonant circuit is again selected for half a cycle so that the screen voltage is rapidly returned to the reference value and if this is not the required new value another of the resonant circuits is switched in to resonantly assist the charge to the new value. As, at each change, the screen voltage is first reset to the reference value by the previously used resonant circuit, the screen is reset without substantial loss of energy. Any energy in fact lost is restored by the voltage supply 6. The switches are preferably such that they open at zero current and a single inductor may replace the three inductors shown.

Abstract: 804,851. Roofs; columns. STUARTS GRANOLITHIC CO., Ltd. June 19, 1956 [March 19, 1955], No. 8058/55. Class 20(4) A pre-cast concrete sectional framework member comprising an upright portion and an extending roof-supporting portion, is characterized by the scarf joint between the said extending portion and the rafter being in a vertical plane so that any stresses induced in the member during the tightening of the joint are normal to the stresses due to the design load. In Fig. 1, the column 10 is concreted into the foundation and the rafter 13 is secured to the extension 11 by a scarf joint 11a, 13a, a yielding packing, e.g. a hardboard washer, being interposed between the surfaces 11a, 13a to accommodate some lack of alignment. The concreting of the upright may be effected after the assembling of the whole framework,. in which case the packing may be omitted. The rafters 12, 13 are hinged at the ridge and, to enable assembly on the ground, a temporary strut spans the rafters between bolt holes 14. The rafter assembly is thus lifted into place and the scarf joints are made, after which the temporary struts are removed. Purlins 15 are of L- section and consist of aligned units, the bevelled scarf joints of which are pivotally connected together above the centre lines of the rafters or extensions 11. Roof sheeting 16 is attached to the purlins. In Fig. 4, the extension ends in a butt joint 17a against which a scarf joint member 17b is strained by post-tensioned reinforcement 18. Alternatively, the rafters may be in two butt - jointed sections with post - tensioned reinforcements, and each two such rafters on each side of the ridge may be integral with one another. If provision is to be made 'for a future additional bay to a building, the upright 20, Fig. 6, is formed with a step 24, to support an oppositely directed extension 23, Fig. 7, and a rebate to receive its end, together with provision for bolting the additional extension to the column. The invention is applicable to saw-tooth section or north light roofing, in which case the rafters, for supporting the unglazed roof areas of lesser slope, are connected to bosses formed as vertical scarf joints projecting from the columns in a direction opposed to that of the extensions which carry the glazing.
