Abstract: 289,981. White, A. E., (Sheaffer Pen Co., W. A.). Feb. 15, 1927. Pen stands.-In fountain-pen stands of the kind wherein a base supports a tubular member having an outwardly flanged upper portion and an internal shoulder for supporting a fountain pen, the tubular member 1, Fig. 2, is secured directly in an inclined recess 10 in a, heavy metal base 4 and is retained in a fixed inclined position relatively to the base. The tubular member 1 is preferably detachably secured to the base by a screw 11, the head of which is received within a recess 12 in the underside of the base and is hidden beneath a felt pad 14 glued to the base to provide a non-abrasive surface. A number of tubular members may be secured to the base, for example as shown in Fig. 1, and the members may be differently coloured to receive pens containing correspondingly coloured inks. The stands may be used also as paperweights. Specification 266,330 is referred to.

Abstract: 747,887. Automatic gain control. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 19, 1954 [Feb. 24, 1953], No. 4960/54. Class 40 (5). In an A.G.C. circuit for a television receiver demodulated video signals are applied to the inner grid g1 of a heptode and positive-going gating signals derived from synchronizing signals to the outer control grid g3. The valve is so biased as to be capable of conducting only (a) during the " back-porch " period, for positively modulated signals on g1, Fig. 2 (not shown), or (b) for the duration of the synchronizing pulses in the case of negativelymodulated signals, Fig. 3 (not shown). The anode supply for the valve is obtained from the receiver line-output circuit 10 via a blocking condenser 9, rectifier 4 and shunt condenser 5. Between the anode of the rectifier 4 and ground are connected resistors 6, 7, the resistor 7 being shunted by a smoothing condenser 8 across which a negative-going A.G.C. voltage is obtained. When the circuit is used with negatively-modulated signals a resistor 2 and shunt condenser 3 are included in the anode circuit of the heptode so that a limiting action is obtained on noise impulses. The rectifier 4 may be replaced by a voltage-dependent resistor.

Title: Method of noble metal catalyst manufacture production of piperitenone
IPC: B01D53/94
Filed: 1974-02-04
Abstract: 1449313 Oxidation catalyst U O P INC 4 Feb 1974 [5 Feb 1973] 05112/74 Heading B1E An oxidation catalyst for noxious exhaust gases is prepared by impregnating a porous refractory carrier material first with a solution of a platinum group metal compound and subsequently with a solution of a calcium, strontium or barium compound wherein the latter solution contains a reducing agent selected from hydrazine compounds, hydroxylamine compounds, water-soluble aldehydes and reducing sugars. The result is that the reducing agent reduces the noble metal compound and fixes the metal on the carrier and obviates the need for an intermediate calcination step between the impregnation steps which is normally necessary to prevent leaching of the noble metal during the second impregnation. Suitably, the noble metal is platinum or a platinum/ palladium mixture in a 4:1 to 1:9 weight ratio. The carrier may be an alumina, alone or deposited as a film on a ceramic material, e.g. a honeycomb. Alternatively, the carrier may be clays, silicates or other refractory oxides. The carrier may be pre-impregnated with an organic dicarboxylic acid before applying the noble metal.
