Abstract: 1,227,636. Jointing; making shafts, print drums. NATIONAL CASH REGISTER CO. 25 Sept., 1969 [27 Sept., 1968], No. 47223/69. Headings B3A and B3V. A drum, particularly a printing drum, is joined to a shaft by shrink fitting an integral hardened contacting surface of the drum on to a hardened external contacting surface of the shaft after depositing on one of the surfaces a layer of softer metal. The drum and shaft are preferably of steel and the layer of soft metal copper which is first deposited as a layer about 0À005 inch thick and then ground to a thickness of about 0À0005 inch. The shaft 16 is made by machining from vacuum melt steel, heat treated and stress relieved then finish machined. The shaft is packed in charcoal to prevent decarburization during heat treatment, which produces an austenitic steel. This is followed by quenching in an oil bath. The shaft is examined for eccentricity or run out, any run out being corrected by selective loading of the shaft, and then tempered at 450‹ F. in a forced air furnace for 2 hours, stabilized at - 120‹ F. for 2 hours and then tempered, unloaded, at 450‹ F. for 2 hours. The hardness of the external contacting surface 18 should now be 58 to 60 Rockwell. The shaft is ground, the layer of copper applied to the surface and ground to the desired thickness. The drum is made from tool steel of wall thickness 0À152 inch with a centre portion 32 of 0À5  inch thickness and heat treated to harden it. The diameter of portion 32 is ground to be 0À004 inch less than the finished diameter of the surface 18 and the two interfitted by freezing the shaft to - 120‹ F. and heating the drum to 450‹ F. Pulleys 22 are shrink fitted to driving surfaces 20 on the shaft by conventional techniques and rotors 28 are shrink fitted to each end.

Abstract: 1,238,009. Radio receiving circuits. RCA CORPORATION. 28 Feb., 1969 [1 March, 1968], No. 10737/69. Heading H3Q. In a VHF-UHF television receiver in which a VHF radio frequency stage with automatic gain control is switchable to serve as an intermediate frequency stage for UHF operation, there is included means for automatically changing the AGC delay on switching over between VHF and UHF modes of operation. RF amplifier 24, Fig. 1, acts as a VHF radio frequency stage in positions 2-13 of switches by which input and output tuned circuits 32, 34 respectively are selected. It feeds VHF mixer and IF amplifier 28 local oscillations being generated by oscillator in positions 2-13 of a switch selecting from oscillator tuned circuits 36. In position 1 of the switches, UHF mixer/oscillator 20 feeds IF signals to amplifier 24, the input and output of which are tuned to the intermediate frequency: RF amplifier 24 and mixer 28 than act as additional IF amplifiers, the oscillator 26 being switched out. An AGC voltage is fed from source 40, which has internal resistance 41, to the RF stage 24 via series connected resistors 42, 48, to the join 44 of which a positive delay voltage is applied from supply B + via series-connected resistors 56, 46. The delay is increased on UHF by means of switch 52, ganged to the station selector switch, which on this range shortcircuits the resistor 46. In a second embodiment, the additional switch 52 is unnecessary: delay is applied to RF stage 24, Fig. 2 via seriesconnected resistors 60, 66 the join of which is connected to the oscillator selector switch 61. On VHF ranges the switch 61 connects the join of resistors 60, 66 to ground via the internal resistance 64 of the oscillator, so reducing the delay.

A cylindrical discharge chamber 5 into which the heavy fraction from a hydrocyclone 1 is fed in a rotary flow is formed in its bottom 10 with an open groove 11 extending around a part only of the circumference of the chamber and leading to a discharge outlet 12, communication between the chamber 5 and the groove 11 being controlled by a shutter plate 14 rotatable about the axis of the chamber for varying the cross-sectional area of the entrance to the groove in the plane of the shutter, the arrangement being such that, in use, the heavy fraction rotates in one direction (arrow 7) within the discharge chamber and is caused to reverse its direction (arrow 20) when entering and passing along the groove. The chamber 5 is located in a casing 8 in the lower part of which is a cylindrical body 9 the upper plane of which forms the bottom 10 of the chamber. The groove 10 which is bounded radially outwards by the wall of the casing increases in width and depth from the level of the plane 10 to that of the outlet 12. The shutter plate 14 is the form of a disc provided with a peripheral recess limited by edges a and b and is rotatably adjustable by means of a shaft 15 and a handle 16, a lock nut 17 being provided to retain the plate in the required position. In use, the heavy fraction discharging from the outlet 4 of the hydrocyclone into the chamber 5 in the direction of the arrow 7 is spread radially outwards by a baffle 13 and flows down the chamber and around the edge a of the plate 14 (arrow 19) and through the groove in the direction of the arrow 20. The edge a may be bevelled. The outlet quantity can be controlled by rotating the plate 14 so that the edge a is situated over different cross-sections of the groove 11, Figs. 7-9 (not shown). The shutter plate 14 and the groove 11 may be modified by giving them different circumferential dimensions, Figs. 10-14 (not shown). In Fig. 15, the peripheral recess in the shutter plate 14b is replaced by holes 18b. In a modification, the bottom body 9 may extend downwards out of the casing or may be replaced by a bottom portion of the casing. Instead of the chamber 5 being coaxial with the outlet 4 of the hydrocyclone, the heavy fraction may be fed to the chamber through a tangential inlet.

Abstract: 1295046 Measuring liquid level PLESSEY CO Ltd 8 Dec 1969 [2 Dec 1968] 57115/68 Heading G1N [Also in Division G4] A liquid level indicator comprises a float attached to a tape passing over a sprocket wheel which is coupled to a continuously rotatable potentiometer, means being provided to count the revolutions of the potentiometer (both upwards and downwards) from a datum to give a coarse indication of level, and the potentiometer itself providing the additional fine measure. The output waveform of the potentiometer will be of sawtooth form and this will be traversed either forwards or backwards depending on the direction of travel of the float, Fig.3 (not shown). As shown in Fig.2 the voltage of the potentiometer P is applied to an ammeter MA suitably calibrated to give fine measure. It is also applied to the base of a transistor TR1 in a Darlington pair TR1 TR2 which are normally conducting. At a time when the steep side of the waveform is being traversed downwards (indicating one direction of the float) the emitter of TR2 goes quickly negative and this is transferred through C2 R11 to a normally conductive transistor TR5 momentarily switching this off so that a Darlington pair TR6 TR7 conduct to operate a a counter CO2. When the steep side of the waveform is being traversed upwards (other direction of the float) the emitter of TR2 goes rapidly positive, causing a Darlington pair TR3 TR4 to be momentarily reduced conductive to operate a counter CO1. The coarse value of level is given by the algebraic sum of the counters which may electro-mechanical stepping devices. Alternatively the outputs of the pairs TR3, TR4, TR7, TR8, may operate to step a single counter in opposite directions. Resetting switches are provided. A non-linear potentiometer is envisaged.
