The ratio of the angular velocity of the light beam to that of the film is maintained equal to the ratio of the arc of the screen to the arc of the screen minus the angular distance between successive film frame centres and the nodal point of the lens system is so located relative to the rotary axis of the system that the ratio of the total arc of the screen to the angular distance between film frame centres is equal to the ratio of the arc of the screen on which appears the image of that part of a film frame which is being projected to the length of that part of the film frame. Several lens systems, mounted on a common carrier rotatable about a common axis may be provided, each lens system co-operating with one of an equal number of light beams. to project a particular film image on to the screen. Thus, as shown, three lens systems 5, 51 and 511 may be provided, said systems being rotatable about a common axis 4. Specification 654,839 is referred to.

Title: Acoustic spectrometer
IPC: G01N3/38
Filed: 1964-05-15
Abstract: 1,049,950. Measuring physical properties of materials. J. V. FITZGERALD. May 15, 1964 [May 17, 1963], No. 20471/64. Heading H4D. Relates to apparatus for automatically recording variations in the acoustic absorption, mechanical Q factor, resonant frequency, modulus of elasticity or other parameters of a vibrated solid material with variation in environmental factors such as temperature, humidity, magnetic or nuclear flux. In a specific embodiment, a test specimen is mounted on supports 10, 11 in a heat-insulating enclosure 12 and is vibrated by a transducer 13 driven by an oscillator-amplifier V 1 . Vibrations in the specimen are detected by a transducer 14 whose output is fed through an amplifier V 3  to the Y-input of a graph-plotter RK and also to a monitoring system comprising an oscilloscope OS and voltmeter VM. The frequency of oscillator V 1  is varied cyclically by a motor M driving variable capacitors C 1 -C 4  in an oscillator frequency-control network N 1 . A rheostat R 41  may be driven in synchronism with the capacitors C 1 -C 4  and co-operate with a voltage source E r  to provide a signal which is an analogue of the oscillator frequency and which is fed to the X-input of the graph-plotter RK. The resonant frequency and Q factor of the specimen are calculated from measurements made on the resonance peaks occurring in . a vibration-amplitude/frequency plot. By means of a heat source such as a lamp 20, a variable thermostat 22, and a motor-driven heat-control switching arrangement 21, 24, the enclosure 12 may be taken through a controlled temperature cycle. A thermocouple 30, indicating the temperature of the specimen, provides an alternative X-input signal for the graph-plotter RK, enabling a plot of resonant vibration-amplitude against temperature to be made. A motor-driven switch 34 permits multiplexing of the two X-input signals so that frequency and temperature plots may be superimposed (Figs. 3 and 5, not shown). The oscilloscope OS may be switched to monitor signals from the oscillator V 1  and the transducer 14 and to measure the phase angle between them. After correction for external phase shifts, this phase angle or loss angle provides a measure of the Q factor of the specimen. For manual operation, the alternative X-inputs to the graph-plotter RK are switched by a switch 35<SP>1</SP>, the capacitors C 1 -C 4  are varied manually, and the oscillator frequency is read from an indicator I 1 . Variation of the performance of the transducers 13 and 14 with temperature may be compensated for, e.g. by a device 13b. Details of the construction of the specimen supports 10, 11 and the transducers 13, 14 (Fig. 4, not shown), and of the enclosure 12, and numerical examples of Q factors and time periods are given.

Abstract: 1424274 Drying particulate materials; cooling granular materials GEORG FISCHER AG 30 April 1973 [1 May 1972] 20519/73 Headings F4G and F4U An apparatus for cooling or drying a particulate material 3, e.g. pre-treated foundry sand, comprises a vertically extending tank 1 having a material supply passageway 2 at its upper end, a vertically extending, perforate gaseous medium feed pipe 4 aligned below the passageway 2 and a plurality of ring discs 6 surrounding and at spaced intervals slong the gas feed pipe 4. Annular spaces 10, 11 are formed between the outer peripheries of the discs and the tank and the inner peripheries of the discs and the gas feed pipe 4. A preferably variable speed, discharge device 8 is located adjacent the lower end of the tank for discharging the material after its downward passage through the tank. In use of the apparatus the material forms generally frusto-conical layers supported by the rings and surrounding the feed pipe, and when gaseous medium is supplied to the feed pipe, successive layers of material in a direction towards the lower end of the feed pipe are treated by progressively lower volume rates of gaseous medium per unit volume of the particulate material. As shown the gas feed pipe 4 is frusto conical and is provided with equal area circular openings. Alternatively the gas feed pipe 4 may be cylindrical (Figs. 2, 3, not shown) and have rectangular shaped openings (Fig. 2) or circular openings of decreasing area (Fig. 3). The pipe may be formed of a plurality of nested frusto-conical rings (Fig. 4, not shown). The rings may be of the same dimensions (as shown) or have different outside diameters and be spaced at the same or different distances. The supply of gas and the starting of the discharge device is triggered by a level gauge 17 which is actuated once the tank 1 is full of the material.

Abstract: 148,556. Wolf, J. May 8, 1919, [Convention date]. Delivering molten metal.-To control the delivery of successive uniform charges of molten glass from the opening S of a tank a, two blades n, n', rigidly mounted on sliding rods o, are employed. The rods o are moved to the right, so as to uncover the opening S, by compressed air acting in the cylinder h. When sufficient molten glass has escaped, compressed air is admitted to the cylinder f, thus moving the cylinder h to the right and so closing the opening S by the blade n<1>. The reverse movement of the rods o delivers the next charge, and so on. The movements of the apparatus may be synchronized with those of the machine receiving the charges by connecting the compressed air control valve with the machine.
