Title: Amplifier circuits, particularly for use in television systems
IPC: H04N5/38
Filed: 1944-05-08
Abstract: 586,683. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 8, 1944, No. 8705. Convention date, May 7, 1943. [Class 40 (iii)] In a circuit for inserting blanking and synchronising pulses, the video signal is fed to the grid of a cathode-follower, an outer electrode being modulated with the blanking or synchronising signals, and the combined signal appearing across the cathode load. The cathode-followers are arranged in cascade and may be coupled by rectifiers to avoid cross-talk. Blanking pulse. Video signals from an Iconoscope, after amplification and subsequent D.C. restoration in valve 23 are applied to the grid of valve 29 operating as a cathode-follower. The output voltage fed across coupling diode 81 is applied to the grid of valve 35 operating as a cathode-follower, the screen of which is normally held at constant potential by the resistor 52 and valve 53 conducting. A positive blanking pulse applied over coupling condenser 69 to valve 65 causes the anode potential to fall thus driving, over coupling condenser 63, the grid of valve 53 to cut off so that the screen potential of valve 35 falls to earth. The voltage appearing across the resistor 55 has the form shown, namely, the video signal with blanking pulse added. To avoid cross talk, diode 81 is arranged to conduct only while the grid of valve 35 is negative with respect to the cathode. When valve 35 is cut-off by the blanking pulse, variations in potential of the cathode of valve 29 are not transmitted through diode 81 to cause grid current in valve 35 and a 'corresponding voltage across the cathode resistor 55. An adjustable bias resistor 81 allows for varying the magnitude of the blanking pulse. Synchronising pulse. The potential across resistor 55 is fed through a limiting diode 87 to valve 45 connected as a cathode-follower. Synchronising pulses are fed over a coupling condenser 90 to valves 93 and 96 and thence to the screen grid of valve 45, the synchronising pulses being inserted in a similar manner to the blanking pulses. The diode 87 is stated to prevent excessive amplitude of synchronising pulse. The video signal with D.C. correction and blanking and synchronising pulses added appears on the cathode of valve 45. Monitoring. The output wave formed may be applied to a monitor over a short cable 106 with a compensating inductance 107. Where a longer cable 110 is to be used the signal is fed across high frequency correcting circuit 117 to a grounded grid tetrode 129 feeding a cathodefollower 134, the output of which feeds over a compensating inductance 140 a cathode ray tube and a synchronising separator circuit.

Title: Improvements relating to the extrusion of plastic material from presses
IPC: B28B3/26
Filed: 1944-05-11
Abstract: 595,835. Moulding hollow articles of clay &c. BESWICK, C. F., and HOLLAND, J. May 11, 1944, No. 8957. [Class 87 (ii)] Clay is forced from an extrusion press 19 Into the space between a core 62 and a segmental mould 44. The segments of the mould are then expanded to free the moulded product 58, and simultaneously segmental knives 21 contract to sever the product from the main body of clay, as shown in Fig. 2. The device shown comprises two flat spaced base rings 11, 12, which are secured by lugs 13 to sleeves 14 slidable on rods 16 fixed at their upper ends to the extrusion press and at their lower ends to a platform 18. On the upper and lower sides respectively of the base rings are disposed secondary rings 22, 37, which may be slid angularly on the base rings by manual operation of push-pull rods 39. This angular movement of the secondary rings does two things simultaneously, viz. (1) by means of pins 25 projecting from the secondary plates into cam slots 27 in the knives 21, the knives are slid towards or away from the core, and (2) by means of pins 29 projecting from the edges 45 of the mould segments into cam slots 33 in the secondary rings, the segments are slid away from or towards the core. The core rests on a block 50 which forms the base of the mould and is hinged at 49 on the edge of a disc 47 slidable on the rods 16. The mould segments are secured to the rings. In operation, the disc 47 is raised, to close the mould space and force the mould against the extrusion press by manual operation of a lever 54 to advance a wedge 53 beneath the inclined base of a stem 51 depending from the disc. The mould space is then filled, and the secondary rings are rocked to expand the mould segments. As the segments expand, they drop off a shoulder 64 on the block 50, and descend on the rods 16, allowing the knives to enter, as shown in Fig. 3. The wedge 53 is then withdrawn, the mould drops, and the product is removed. Specification 545,335 is referred to.

Title: Improvements in or relating to machines for forming or measuring bevel gear teeth
IPC: B23F5/06
Filed: 1949-04-14
Abstract: 689,192. Gear-cutting or grinding. DEAKIN, T. M. April 14, 1950 [April 14, 1949], No. 9279/50. Divided out of 10235/49. Class 83 (iii). [Also in Groups XIX and XXIII] A machine for forming or measuring the profile of a bevel gear tooth comprises a first rigid member 11 having an arcuate portion 14a and representing the generating plane of the tooth profile, a work carrier 12 for the gear blank 16, the member 11 and the carrier 12 being relatively movable about the axis of the arcuate portion, a second rigid member 20 secured to the work-spindle 19 and having an arcuate portion representing the gear cone to be rolled on the plane, rectilinear slide means 14 for connecting both arcuate portions in non-slipping relationship, and a tool 21 movable to engage the blank along the generator of the tooth profile. The disc 11 is fixed to the machine frame 10 and represents a great circle of an imaginary sphere S. The carrier 12 is oscillatable about the axis OX of the sphere S and carries the blank or partly-finished gear 16. The carrier 12 also supports the slide 14 which contacts the disc 11 in non-slipping relationship at 14a, so that upon oscillation of the carrier, the slide is reciprocated. The blank 16 is carried so that its axis intersects the point O, and is rotated by the disc 20 which contacts an edge 14b in non-slipping relationship and has a diameter equal to AQ. The generating motion imposed represents the rolling of the cone OAQ on the sphere S. The grinding wheel 21, or single or multiple-edge cutting tool, is reciprocated on a slideway 23 which is pivoted about the axis OX for feed purposes or for providing tip relief. If a grinding wheel is used the generating motion is rapid and the reciprocating speed of the wheel slow, but, if a cutting tool is used, the reciprocations are rapid and the generating motion intermittent. The slideway 23 may be offset, as in Fig. 6, to produce spiral bevel gears with straight teeth. A second tool may be provided. In a modification, the blank 16, Fig. 7, is carried on a member 15 adjustable on an arcuate surface 24 of a cross-slide 25. The edge of the member 14 in contact with the disc 20 is adjustable by means of a member 27. The machine may thus be set for forming involute profiles or standard profiles. The wheel 21 may be replaced by a cup-wheel for curved-tooth gears. The tool may be replaced by a feeler to check the tooth shape.
