Title: Improvements in or relating to Bottle-making Machines.
Inventor: WADE HAROLD
IPC: C03B9/325
Filed: 1918-04-26
Abstract: 123,236. Wade, H., (Lorkwood, L. V.). April 26, 1918. Blowing.-Consists of mechanism for forming a, bottle-neck with an internal groove of the form described in Specification 25440/11, [Class 125 (iii), Stoppers &c.]. The invention is described as applied to a rotary machine in which a series of five parison moulds are mounted on a table which receives an inter. mittent movement. Fig. 7 shows in part one of the moulds C with the groove-forming mechanism in its operative position. The groove is formed by the rotation of bits 18b formed on the upper part of pivoted levers 18 carried by a block 17<a> adapted to slide in an opening formed in the adjacent parts of the table B, the fixed mould base-plate C<1>, and an under plate C<2>. The block 17<a> is mounted on a spindle 17 sliding in a cross piece C<3> and provided with a head 22<a> to limit its movement. A pinion 4 is splined to the spindle 17, but is free to slide thereon. The boss of the pinion carries a cross-pin 27 passing through a slot in the spindle and connected by a spring 24 to a pin 25 fixed to the spindle. The mould C is shaped to engage the flanged upper part 11 of the base-plate C' and is adapted to receive the head C<5> of tongs, shown in Fig. 10, which form the outer part of the neck and serve for the removal of the bottle. The operation of the machine is as follows. Molten metal having been placed in the closed mould, the table is moved forward and at the next stage a cap is brought down on the mould and compressed air is admitted to force the glass into the neck-forming parts which are in the position shown in Fig. 7. The mould is held closed by a forked piece actuated by a piston and engaging lugs on the mould halves and the gear 4, which has been raised by a stationary cam, engages a supporting lever and also gears with a pinion actuated by an electric motor. The levers 18 are thus revolved and the groove is formed by the bits 18<b> which have been moved outwards by the raising of the gear 4. During the next movement of the table, the bits 18<b> are moved inwards and the block 17<b> is lowered. The descent of the block opens communication with a conduit through which compressed air is admitted to blow the parison. The blowing is effected while the table is at rest and the mould is locked by a device similar to that used at the neck-forming stage. Further movement of the table causes the mould tu be opened and allows the parison to be removed in the tongs. The moulds are opened and closed by sliding blocks actuated by a central stationary cam and connected by links to the pivoted mould sections. Each of the five moulds operate in succession. The table is actuated by a reciprocating piston and is fitted with locking mechanism as usual.

Filed: 1946-03-09
Abstract: 609,258. Impedance networks. WHITE, E. L. C., and WATTON, W. L. March 9, 1946, No. 7395. [Class 40 (viii)] A bridged-T network is designed to neutralize phase - distortion, particularly that due to band-pass filters in television receivers, in which the frequency characteristic of the phase delay deviates from linearity skew-symmetrically, i.e. is an odd function of the frequency-deviation. The elements have the values shown in Fig. 1, where Z1, Z2 are impedances and c is a constant, the characteristic impedance R having a constant value -(Z1Z2). The case in which Z1 is inductive and Z2 capacitive, Fig. 3, (not shown), is worked out in the Specification and it is shown that for small deviations dp from a value po of the pulsatance, which is such that Z1-c=jr and that the phase delay is (- #) for all frequencies, there is a constant time delay (corresponding to a term 4#c.dp/po in the phase-deviation) together with a phasedelay proportional to (dp/po)<3>, which constitutes a correcting term, together with higher powers which are negligible. Equivalent lattice networks are given in Figs. 2, 4 (not shown). The phase characteristic depends on the value of c, which must be greater than unity unless Z1 is inductive, in which case negative mutual inductance can be introduced if necessary. Specification 342,307 is referred to.
