Abstract: Isophorone is converted to 3,5-dimethylphenol in the gas phase in the presence of a catalyst comprising one or more catalytically active rare earth metals on alumina, preferably promoted by a transition metal, e.g. cobalt, and/or an alkali or alkaline earth metal, e.g. potassium.

Abstract: A polarizing beamsplitter device uses as a beamsplitter a surface relief transmission grating (26) formed so as to have a high diffraction efficiency for S component light and a high transmittance for P component light. In one embodiment relating to a laser read/write system, the grating is used in conjunction with a wave retardation device (28). In this embodiment, light (22) from a laser (20) is incident at about 45° onto the grating (26). The diffracted S component, which leaves the beamsplitter perpendicularly to the incident beam, passes through a λ/4 wave retardation plate (28) and is focussed by lens (30) onto a video disc (24). Reflected light passes back through the lens and the wave retardation plate, emerging from the plate (28) as a P polarized beam. This beam passes straight through the grating (26) to fall on a detector (32).

Abstract: A transfer device to transport a film card from a film platform of a microfilm reading machine to a cassette and in the reverse direction has a transport device which has two mutually opposite rotary disks which are approachable towards each other like the jaws of tongs. This transport device is capable of moving towards the film card, so that the film card passes between the disks. One of the disks is driven so that the film card is transported as soon as it passes between the disks. Due to the arrangement of a pair of disks, the transport device is extremely flat so that it can withdraw a film card from a cassette without the need for it to be slid into the induction region of the transport device by means of, for example, a ram.

Abstract: A line circuit includes tip and ring voltage amplifiers (20, 40) each having an output resistively connected via tip and ring feed resistors (12, 13) to tip and ring leads (2, 3) in a telephone line. The tip and ring feed resistors have closely matched ohmic values, and are part of a resistance network (10) which also includes first and second voltage dividers (14, 15). The first voltage divider (14) is connected in series between the output of the tip voltage amplifier and an end of the ring feed resistor remote from the output of the ring voltage (15) amplifier, and includes a first voltage tap (6). The second voltage divider is connected in series between the output of the ring voltage amplifier and an end of the tip feed resistor remote from the output of the tip voltage amplifier, and includes a second voltage tap (7). A control circuit (60) includes a differential input connected across the first and second voltage taps. In operation the control circuit causes the tip and ring voltage amplifiers to provide energizing direct current for the telephone line. Tip and ring feedback networks (16, 17, 18, 19), connected across the respectively tip and ring feed resistors, provide feedback signals to the tip and ring voltage amplifiers such that in operation common mode rejection of longitudinally induced a.c. signals on the telephone line is enhanced.

Title: An atrial synchronized pacemaker having an adaptive atrial refractory period
Inventor: CITRON PAUL
IPC: A61N1/365
Filed: 1984-03-05
Abstract: An atrial synchronized pacer having an atrial refractory period which is extended in response to the detection of retrograde activated P-waves for interrupting pacemaker meditated tachycardia. Atrial sensing amplifier 14 supplies atrial sense signals to A-V timer 20 and atrial refractory timer 30. After the A-V delay, timer 20 produces a ventricular pacing pulse, which may be delayed by upper rate limit timer 60. A V-A time measuring circuit 40 measures the times between ventricular and atrial pulses and if the times are both short and invariant, indicative of the detection of retrograde P-waves, atrial refractory control 50 operates to extend the atrial refractory period so that the pacer does not respond to the retrograde P-waves.

Abstract: A liquid phase oxidation reaction is carried out by withdrawing a stream aqueous reaction medium from a tank 2, heating it e.g. in heat exchanger 24 an then returning it to the tank 2. Once a chosen reaction temperature is attached oxygen is added to the stream in a venturi 18 and the heating is discontinued. The stream containing fine bubbles of oxygen is re-introduced into the tankthrough nozzles 30 so as to dissolve substantially all the oxygen. By avoiding evapora- ture losses caused by undissolved gas breaking the surface of the liquid phase, requirements for external heat can be minimised. Oxidation reactions involving the formation of salts from metals in acid media may be carried out by this method.
