Abstract: 230,276. Miller, W. J. March 18, 1924. Blowing. - A transferring or take-off mechanism for use in a glassware forming machine has a suction device for gripping the open end of the glass article. The device consists of a casting 1, Fig. 1, having a flanged lower portion 3 whose inner edge is recessed to fit the top edge of the parison B or other article to be gripped. The casting is connected by a ball and socket joint 6 with a. stem 7, air passages 19, 24 making connection between the space 11 within the flange and a flexible pipe 27 which is connected with the vacuum tank. A circular plate 9 is mounted within the head by a screwed stem 10, and a passage 13 closed by a ball valve 16 is open at one end to the atmosphere and at the other end to the space below the plate 9. The stem 7 encloses a valve 29 which, when turned, shuts off the passage 24 from the tube 27 and connects it with the atmosphere through a port 28. The device is shown in Fig. 4 in conjunction with a pneumatically operated mechanism for transferring parisons from a blank mould D to a blow mould F of a double-table forming-machine. The valve in the stem 7 is operated by a winged head 41 that makes contact at appropriate times with stops 42, 44 fixed on the machine. The stop 42 turns the valve to permit air to be sucked from the head 1, and the stop 44 turns the valve to connect the passage 24, Fig. 1, with the atmosphere, or a source of higher pressure, in order to detach the parison from the head. The ball valve 16, which is adjustable, prevents the pressure within the parison falling to a point which would cause the parison to collapse. In a modified construction, the plate 9 is replaced by a block which extends downwards within the parison and is suitably shaped to engage its inner surface.

Title: Iron plating bath liquids and methods
IPC: C25D3/20
Filed: 1966-02-17
Abstract: Electroplating with iron is effected from an acid aqueous solution containing a ferrous salt and, as a dispersant for ferric hydroxide, a condensation product including the grouping A-R-A1-SO3 where R is a methylene radical or a straight or branched chain aliphatic nucleus and A and A1 are like or different aromatic groups each containing a naphthalene nucleus joined to R. Typically the ferrous salt is the chloride and the condensation product used is the sodium salt of the product formed by condensation under acid conditions of a b -naphthalene-mono-sulphonic acid and formaldehyde present in a 2:1 molar ratio and is used in the plating bath at a concentration of 0.25 to 1 g/l.  The bath contains a small amount of free hydrochloric acid and examples are given in which the ferrous chloride content is 187 or 454 g/l.  Aluminium pistons for I.C. engines may be plated with hard iron layers by first etching in a nitric acid-hydrofluoric acid bath, then zinc plating by immersion, rinsing, electroplating with copper from a cyanide bath, rinsing, dipping in dilute hydrochloric acid, and then immersing with the current on into the iron plating bath at a temperature of 60 to 71 DEG C. and employing a cathode current density of 100 to 125 amps/ft2.  An outer layer of tin may then be electroplated from a stannate tin bath containing free potassium hydroxide.  Reference is made to producing soft iron electrodeposits at bath temperatures of 82 to 88 DEG C.

Title: Improvements in and relating to the treatment of tubing
IPC: D06C5/00
Filed: 1943-05-04
Abstract: 570,373. Liquid treatment of flexible tubing. BRIGGS MANUFACTURING CO. May 4, 1943, No. 7025. Convention date, May 9, 1942. [Class 140] In the treatment of flexible (e.g., fibrous) tubing with a liquid (e.g., resinous) composition, the tubing is passed through the liquid so that this is applied to both the inner and outer surfaces, and is then fed through a doctor device which removes excess liquid from both surfaces and comprises a tube containing an element (e.g., an iron ball) which is magnetically held within the tubing. The inner surface of the doctor tube may make actual contact with the outer surface of the flexible tubing. As shown, apparatus for impregnating a length of fibrous tubing, as of woven wool, cotton, silk, or glass with resinous material, e.g., a phenol-formaldehyde resin, comprises a tank 16, Fig. 1, for the resinous liquid. which may be heated by coils, and through which the tubing 10 is passed over pulleys 18. 20, 21 from a supply roll 11. From the tank the tubing is delivered through a doctor A via curing and cooling stacks 43, 44 and a pulley 34 to a take-up roll 37. The doctor A comprises an open-ended tube 28, Fig. 3, of non-magnetic material such as copper, brass, bronze, or stainless steel, enclosing a ball 27 of magnetic material which rests on a shoulder formed between two sections 29, 30 of the tube having diameters respectively greater than and less than that of the ball ; an intermediate annular casing 42 through which hot oil, water, or steam may be circulated ; and an outer annular casing 25 containing a solenoid which serves both to hold the ball 27 in position within the tubing 10 as this is fed through the tube 28, and also to heat the ball by induction. Using phenol-formaldehyde as the resinous material, the temperatures of the tank 10 and doctor A are maintained around 240‹ F. and 220‹ F. respectively. In the curing stack 43 the temperature is maintained at about 300‹ F. to cause polymerization of the resin. Various other shapes of the magnetic element 27 are referred to. Reference is made to a similar known treatment in which the magnetic element operates without the external doctor tube.

Title: Improvements in or relating to flexible couplings
IPC: F16D3/58
Filed: 1943-05-04
Abstract: 564,400. Flexible shaft couplings. FAWICK, T. L. May 4, 1943, No. 7034. [Class 80 (ii)] In a flexible shaft coupling one coupling member 10 has a circumferential series of cylindrical holes, each receiving a rubber block 11. Adjacent holes are inter-connected by arcuate recesses 12 which receive axially extending fingers 17 formed on a ring 16 bolted to the other coupling member 14. The sides of the fingers 17 thus engage the outer faces of adjacent rubber blocks to transmit -torque. A bolt 18 passes through each block 11 so that by tightening a nut 19 the block is axially compressed and radially expanded to press against the fingers 17 and against the arcuate walls 11a, 11b of the cylindrical holes. The amount of compression determines the damping effect of the coupling.

Title: Improvements in or relating to ultra high frequency radio signalling systems
IPC: G01S1/02
Filed: 1942-05-22
Abstract: 557,563. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., EARP, C. W., and STRONG, C. E. May 22, 1942, No. 7035. [Class 40 (v)] In an ultra-high frequency radio system in which signals are conveyed by keying interruption or amplitude modulation, the carrier wave is frequency-modulated about a mean frequency and at the receiver is heterodyned with a constant frequency substantially equal to the mean carrier frequency. The frequency modulation is a periodic frequency sweep as indicated .in Fig. 2a, the repetition frequency being higher than the highest signal frequency. At the receiver, Fig. 1, the incoming wave is heterodyned by a wave of about the mean incoming frequency and the difference frequency is passed by resistancecapacity couplings through the I.F. stages V<SP>3</SP>, V<SP>4</SP> to a second detector D2. The couplings are such that low frequencies up to about 10 kc. and frequencies above 1 mc. are suppressed, with the result that energy reaches the second detector D2 in the form of pulses at the repetition frequency as indicated in Fig. 2. The width of the pulses is determined by the relative values of the frequency sweep at the transmitter and the band width of the receiver I.F. stages. The pulses may be passed through a valve V<SP>5</SP> with an output circuit tuned to the pulse frequency, to an output transformer T. The heterodyne may be provided by a crystal oscillator V<SP>1</SP> with its plate circuit tuned to a harmonic of the crystal frequency and feeding a harmonic generator V<SP>2</SP> giving a further multiplication of frequency in the circuit C<SP>1</SP>, L<SP>1</SP>. A resonant concentric line CTL is tuned by a condenser C<SP>2</SP> to the mean carrier frequency, and the incoming carrier and the oscillation in C<SP>1</SP>, L<SP>1</SP> are both applied to the line and to a diode D<SP>1</SP>, the beat oscillation being developed across the resistance R<SP>1</SP>. The wave form of the frequency modulation may be sinusoidal or sawtooth, and the modulation may be effected as described in Specification 556,208.
