Title: Method and apparatus for the separation of samples of solid particles into sized fractions
IPC: B03B9/00
Filed: 1961-07-25
Abstract: 988,577. Cyclone separators. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANISATION. July 25, 1961 [Aug. 1, 1960], No. 26966/61. Heading B2P. A sample of solid particles of different size, shape or specific gravity is separated into fractions by introducing the sample into the fluid stream of a cyclone elutriator, retaining in the elutriator particles with a settling rate greater than a predetermined minimum during a time sufficient to ensure that they repeatedly traverse the flow pattern of the elutriator, and finally discharging these retained particles from the elutriator. The cyclone 1, Fig. 2, has a tangential fluid inlet 5, a vortex finder 6 and an underflow discharge orifice 4 above which is located a detachable, transparent-sided sample container 7 provided with a plug 9 and a discharge valve 11. At the start of an operation the solid particles forming the sample are contained in the container with the orifice 4 sealed by the plug 9 and the valve 11 closed. Fluid is then introduced in the cyclone at a greater flow rate than that selected for elutriation and the plug 9 is removed. The underflow discharge enters the container 7 and creates a swirling flow entraining the particles in the cyclone. The slower settling particles are discharged through the vortex finder 6 while the faster settling ones are returned by the fluid flow to the container 7 and recirculated. The flow rate is then decreased to and maintained at a predetermined value to obtain the required separation during elutriation at the end of which it is further increased and the valve 11 is opened to effect discharge of the faster settling particles. A number of similar cyclones may be connected in series for separating the particles into a number of sized fractions. The sample to be elutriated may be placed in the sample container of the first cyclone or it may be introduced in the fluid flowing to that cylone. The inlet of each succeeding cyclone is connected to the vortex finder of the preceding one.

[Class 40 (iii)] Wireless control of cathode-ray receivers. In a television system in which picture signals and sound signals are transmitted on two different carriers, the carrier which bears the sound signals is additionally modulated for the purpose of line-scanning with a saw-tooth wave-form having a fundamental frequency equal to the line frequency, which may be 4500 c. /sec., while the sound-transmission may be cut off by filters above 4000 c. /sec. The width of the relevant band may be restricted to 50000 c. /see. so that the points of the saw teeth are rounded off. Thus the time-frequency deflecting field can be produced at the receiver by means of a direct-current amplifier valve. The frame frequency can be synchronized by cutting off both picture signals and timesynchronizing signals at the end of each frame and using at the receiver a spill-over generator of the thyratron type which pulls into step with these interruptions. Generating saw - tooth wave - form. The required wave-form may be generated at the transmitter either by a spill-over generator or by a Nipkow disc having a set of triangular apertures which pass between a slit-shaped light-source and a photoelectric cell, the width of the slit determining the degree to which the points of the wave-form are rounded off.

Title: Improvements in or relating to telephone answering and recording devices
Inventor: WARREN WILLIAM EDWARD
IPC: H04M1/65
Filed: 1960-08-04
Abstract: 974,621. Substation circuits. SOUTHERN INSTRUMENTS Ltd. Nov. 6, 1961 [Aug. 4, 1960], No. 27103/60. Heading H4K. In an automatic telephone answering system in which the answering device is in shunt with the associated handset, means are provided in the device whereby if the handset is lifted, the impedance presented to line by the device is automatically altered so as to maintain a substantially constant impedance termination of the line. In Fig. 1, the answering device A is connected in shunt with handset T as shown, and in response to incoming ringing current contacts 8 and 10 are closed by means not shown, provided that the handset is on-hook. If the handset is now lifted, loop current flows through relay 4 which comes up so as to cause contacts 8 and 10 to open, thereby increasing the impedance of the device so that mismatching of the handset and the device to the line is prevented. In the device shown in Fig. 3, a contact 22 automatically closes when the answering device responds and the zone diodes 12, 13 conduct so as to maintain the line loop via inductance 15 and to prevent the optimum A.C. impedance to line via impedance 14. If the handset is now lifted the diodes stop conducting in order to restore the proper terminating impedance. Signals from the device are transmitted through inductance 15, which constitutes the secondary winding of a transformer, into the line and during such transmission contacts 16 are closed in order to maintain the transmission in the event that the handset is lifted. The signal strength in this case must be such that the resulting mismatch is overcome. Another embodiment, utilizing a D.C. amplifier in the bell circuit of the instrument for detecting changes in line current when the handset is put on or off hook is described with reference to Fig. 5 (not shown). In the embodiment depicted in 6, contacts LS1, LS2, LS3 are operated in response to ringing current whereby zones diodes D6, D7 break down to render transistor X6 of the bi-stable circuit X5, X6 conductive and so bring up relay HL. In the event that the handset is now lifted the resultant decrease in line potential causes transistor X1 to cut-off so switching on transistors X2 to X5 whereby HL falls back to remove the low impedance circuit R2, R3, L1 from across the line.
