Filed: 1973-12-18
Abstract: 1459759 Labelling apparatus R A JONES & CO Inc 18 Dec 1973 [18 Dec 1972] 58637/73 Heading B8F In labelling apparatus in which an applicator roll 5 applies a heat-softenable adhesive to a label web 60 having labels L partially cut therefrom and a reciprocable plunger 35 presses a label from the web and through an aperture in a support plate 32 on to an article T, such as a bottle, the web is intermittently clamped against the support plate in timed relationship with plunger movement by a clamp 11 which engages the adhesive side of the web and which is heated to prevent the build-up of adhesive thereon. The clamp comprises a reciprocable plate 20 having an aperture 21 through which the plunger may pass and over which an electrically heated resistance element 25 is secured Fig. 3 (not shown). The element presents heated fingers 24, the tips of which follow the contour of the label to be applied and project out the plane of the element to press the web portion surrounding the label against the support plate. The fingers are maintained at the temperature at which the adhesive is applied to the web i.e. in the range of 300-340 F. An endless flexible band 42 is secured to the support plate and is urged by air jets 41 against the label web to minimize web tensions induced by the change from continuous web motion past the applicator roll to intermittent motion past the label-applying plunger. The labels are partially cut from the web except for small rupturable junctions and may be arranged in spaced or contiguous relationship in the web, Figs. 5-7 (not shown). The applicator is provided with spaced pockets 52 to apply the adhesive to the labels arranged in spaced relationship in the web, said adhesive also extending over the label boundaries on to the web remnant. Alternatively, the adhesive may be applied over the whole of the web or in the form of two lengthwise-extending strips. In the latter case, the heater element fingers need not extend completely around the label periphery, Fig. 8 (not shown).

Title: Watches and other time-pieces
IPC: H02J7/35
Filed: 1971-12-20
Abstract: 1339637 Battery charging apparatus SUWA SEIKOSHA KK 20 Dec 1971 [29 Dec 1970 18 Feb 1971] 59064/71 Heading H2H [Also in Division G3] In an electronic timepiece (e.g. a watch) a secondary battery 4 which supplies the timepiece circuitry 5, is charged by a solar cell 1 and to prevent excessive charging current, during subjection of the solar cell to relatively high light intensity, the solar cell is shunted by the collector/emitter circuit of transistor 2. Thus as the solar cell output voltage increases the transistor becomes increasingly more conductive so decreasing the current flowing to battery 4. A diode 3 prevents discharge of battery 4 when the solar cell output voltage is low, during darkness. Various modifications are illustrated Figs. 2, 3, 5 and 7 (not shown), whereby the transistor base potential is made to vary with tne charging current. In Fig. 5 (not shown) for example the base is connected to the junction between a thermistor and resistor connected in series across the solar cell. The thermistor is said to compensate for temperature effects on the transistor. It may be arranged that the transistor becomes conductive when the charging current exceeds 5mA.

Abstract: 1395699 Mounting rear-view mirrors; mounting sun-visors SURREY STEEL COMPONENTS Ltd and J. S. CONN 30 Jan 1973 [21 Dec 1971] 59412/71 Heading B7J [Also in Division E2] An article such as a rear-view mirror is mounted on a vehicle by means comprising a mounting portion 10, Figs. 1 and 3, adhesively securable to the vehicle and having aligned channels 35, 36 therein, and a carrier portion 21, Figs. 4 and 5, connectible to the mirror at a ball 23 and also having a channel 26 therein defined by lugs 25 so that when the carrier portion 21 is arranged on the mounting portion 10, the lugs 25 and channels 35, 36 are in registration and channel 26 receives a resilient locking member 28, Fig. 8, thus locking the portions together. Channel 26 and further channels 16 and 19 in portion 10 have V-shaped grooves 17, 20 and 27 along each side wall and thus are of decreasing cross-section towards the mouth of each channel to normally retain the locking member 28 therein. When the portion 21 or mirror thereon receives a severe blow in an accident, the resilient member 28 is pulled out of the mouths of channels 16 and 19, or out of the mouth of channel 26, so as to release the portions 10 and 21 from one another. The member 28 is of hexagonal cross-section cooperating with the V-shaped grooves 17, 20 and 27 and has a slot 34 therethrough to enhance its resilience. The member 28 may be connected to portion 10, and the shape of the channels 16, 19, 26 and member 28 may be chosen so that the member tends to remain in a selected one of the portions 10 and 21 on break-away. Such mounting means may be used to mount other articles such as sun-visors or ash trays on a vehicle.

Title: Process for the production of phthalic anhydride from phthalic acid
IPC: C07C51/56
Filed: 1969-12-05
Abstract: 1282329 Preparation of phthalic anhydride CHEMISCHE WERKE HULS AG 5 Dec 1969 [7 Dec 1968] 59428/69 Heading C2C Phthalic anhydride is produced by introducing phthalic acid into phthalic anhydride at a temperature of from 160 to 200 C. (the temperature being maintained in this range) in the presence of a small amount of an entrainer, for the water evolved, and the evaporated water entrained with the entrainer is separated therefrom and the entrainer is returned to the phthalic anhydride melt. The entrainer may be known hydrocarbons which form an azeotrope with water as for example benzene, toluene, ethylbenzene, the xylenes, cumene, diethyl. benzene, diisopropylbenzene. It is advantageous to use o-xylene as entrainer since the oxidation of o-xylene to o-phthalic acid and the conversion of the latter into phthalic anhydride can be carried out in successive reaction stages without extraneous substances being introduced into the whole process o-xylene being returned direct into the oxidation step.

The aqueous medium may contain an acid or base, e.g. HCl, NaHCO 3  and the reaction is preferably carried out at a temperature of from 10‹ to 40‹ C. The enamines of Formula II may be prepared by contacting a compound of Formula III with an acetal of a N,N-disubstituted formamide of Formula IV where R 3  and R 4  are C 1  to C 8  alkyl, or with a tris (secondary amino) methane of Formula V or with a tris (secondary amino) C 1  to C 8  alkoxy methane of Formula VI where R 5  is C 1  to C 8  alkoxy. A preferred solvent medium for the reaction comprises an N,N-disubstituted formamide of general formula and a secondary amine of formula the reaction preferably being carried out at a temperature of from 10‹ to 40‹ C. Compounds of Formula III may be prepared by contacting a compound of Formula VII with a base in an aqueous medium, e.g. aqueous sodium hydroxide preferably at a temperature of from 10‹ to 40‹ C. Compounds of Formula III where R = H may be prepared by (a) contacting a compound of Formula X with H 2 O 2  and a basic catalyst in an inert solvent medium to yield a compound of Formula XI (b) contacting the resulting compound of Formula XI with a strong base in an aqueous medium to yield the salt of the acid of Formula III and (c) liberating the free acid by contacting with a strong acid. A suitable basic catalyst for step (a) is an alkali metal hydroxide and the epoxidation is preferably carried out at 0‹ to 10‹ C. The strong base used in step (b) is preferably an alkali metal hydroxide and the reaction is preferably carried out at 20‹ to 40‹ C. The strong acid used in step (c) can be a mineral acid, e.g. HCl, H 2 SO 4  or an organic sulphonic acid, e.g. p-toluenesulphonic acid. Compounds of Formula X may be prepared by condensing 1,3-indandione with the appropriate aldehyde R<SP>1</SP>CHO. The compounds of Formula I react with primary amine-containing compounds, particularly polypeptides and amino acids, to form highly fluorescent products. This reaction therefore serves as a basis for a rapid and sensitive assay method for primary amine-containing compounds.

Abstract: 1372107 Digital transmission; demodulating RICOH KK 30 Dec 1971 [31 Dec 1970] 60657/71 Heading H4P In a demodulator for a system in which a mark is coded as a determined number n of pulses, and a space by zero current, or conversely, and a capacitor used to sum the pulses, a capacitor charge means is provided and rendered operative when one type of binary signal is received and a discharge means is rendered operative by the other binary signal. The arrangement is stated to guard against a false binary output for input signals having occasional missing pulses, or alternatively spurious noise pulses during zero current periods. Signals received on. terminal 1 are passed through a circuit 3 which charges a capacitor 5 each time a pulse is received, and through inverter 2 a first discharge circuit 4 is activated when the pulse disappears, also AND 11 is primed so that lack of signal output on terminal 10 activates a discharge circuit 12 discharging capacitor 5 at higher rate. Threshold detectors 7, 8 are set at different levels so that a series of pulses hold flip-flop 9 in a set position, but discharge of capacitor 5 below a determined level resets it and activates discharge circuit 12. An occasional missing pulse will therefore not cause flip-flop 9 to reset, or alternatively a noise pulse in a "space" period will not set it.
