Title: Improvements relating to the attachment of plug sockets or the like to articles suchas zinc battery cans
IPC: B23K1/06
Filed: 1933-03-20
Abstract: 408,095. Making galvanic batteries. KLEINMANN, E., and MENDEL, A., (trading as KLEINMANN, GEB.), 21, Wilhelmstrasse, Lichtenberg, Berlin. March 20, 1933, Nos. 8442 and 8443. Convention dates, March 19, 1932 and Dec. 20, 1932. [Classes 83 (ii) and 83 (iv).] A machine for the attachment of plug sockets to zinc battery cans has means for positioning the sockets opposite the cans in correct soldering position and means for effecting soldering. Blanks transferring. The sockets are fed from a grooved casing 63 by a rotor driven from a shaft 13<a> and drop leg downwards from a shoot 14 to holders 9 on a conveyer 1. The cans are carried in pockets 10 on a conveyer 2 geared to the conveyer 1. The sockets are applied to the cans by a ram 36 and are then transferred by the cans to the conveyer 2. As the sockets emerge from the shoot 14 they are gripped by cam-operated fingers and aligned by a cam-operated slide 15 against a guide 14<a>. A device 31, Fig. 6, rotated one revolution and moved axially by cams 23 engages the legs of the socket to turn it long legs uppermost. The hole in the socket is then engaged by the ram 36 reciprocated and raised by cams to position the legs astride and to force them over the can edge. A container 44 is lowered by a cam to apply liquid flux and a soldering wire 56 is fed through a steatite or hard glass nozzle 58 and applied, to secure the socket, by an electrically heated soldering iron 49 lowered by a cam. The parts are driven from a common shaft 11. In a modification a single conveyer for the cans and the sockets is used. The sockets are fed by a toothed disc down a shoot with an escapement for liberating single sockets and an overflow for excess sockets. Cam operated clamps then hold the sockets and the cans to the conveyer until the ram 36 has operated. The sockets are then fluxed and soldered. If additional connecting wires are to be soldered to the cans a cam-operated rod pushes the socket clear of its holder. Camoperated fingers hold the can and turn it to soldering position, flux spread by a sponge and solder are applied as before. The wire applying mechanism may be duplicated.

Title: Improved method and apparatus for the continous production of a web or mat of staple fibres
Inventor: STEWART DANIEL SAMUEL
IPC: D04H1/4218
Filed: 1969-02-18
Abstract: 1,234,722. Lap forming machines. REGINA GLASS FIBRE Ltd. 10 Feb., 1970 [18 Feb., 1969], No. 8695/69. Heading D1N. A fibre web is made by spinning glass filaments onto a drawing drum 2, scraping the filaments from the drum as staple fibres and delivering them in a current of air created by the rotation drum 2 within a shroud 4, delivering the fibre stream onto a conveyor as a web, impregnating and finishing the web. The process is characterised by guiding the staple fibres away from the drum along a feed axis which extends across and above the conveyor at an angle other than 90‹, thence downwardly into a delivery area which does not move. The size and shape of the outlet 6 of the duct 5 which guides the fibre stream can be varied to produce a desired fibre density pattern in the web, (see Figs. 2 to 5). The angle between the feed axis and the conveyor direction may be variable. The density of the deposited web may be sensed and any resulting variation in density determined used to produce a signal to a control device to alter the outlet 6 so as to compensate for irregularities in density.

Title: Improvements in or relating to radio direction finders
Inventor: BYATT DENNIS WILLIAM GEORGE
IPC: G01S3/14
Filed: 1965-03-02
Abstract: 1,060,704. Radio direction finding. MARCONI CO. Ltd. Jan. 24, 1966 [March 2, 1965], No. 8944/65. Heading H4D. A radio direction finder is designed to be less susceptible to changes in polarization of the incoming wave by having a rotating aerial system comprising one aerial receptive only to horizontally polarized waves and one aerial receptive only to vertically polarized waves and alternately switching the outputs of the two aerials to a receiver at a rate high in relation to the rotational rate of the aerial system, such that in the detected output of the receiver, momentary variations in the output of one aerial due to changes in incoming wave polarization are averaged out with the output of the other aerial, and allows a normal phase comparison between the envelope of the detected receiver output and a reference signal in synchronism with the rotation of the aerial system. The system may comprise, Fig. 1, a connected dipole D1 with a parasitic reflector D2, spaced by a quarter wavelength, and susceptible only to vertically polarized waves, and a connected loop L 1  with a parasitic loop L 2  susceptible only to horizontally polarized waves. The aerial system is rotated by a motor M about an axis MS on the end of an arm B at a rate of 1 rev./sec. The polar diagram of each aerial is a cardiod, and signals with sinusoidally varying amplitudes are induced in respective rotary transformer secondaries C 1  and C 2 . The signals from the two aerials are fed to a switching system S which switches the signals to a receiver R alternately at a rate of 1À5 kc./s. The form of the input signal to the receiver R for a polarization direction of 45 degrees is shown in Fig. 2 (not shown). The receiver detects its input signal and passes the resulting envelope to one input of a phase detector PD. The other input is fed by a generator G, coupled to the motor M. The output of the phase detector is fed to a direction indicator I. Although the aerial system can be rotated about an axis passing through the middle thereof, a larger, more accurate base line is simulated by the rotational method described. A second aerial system may be provided rotating with that shown and diametrically opposite thereto, one dealing with V.H.F. waves and the other with U.H.F. waves. Although separate rotary transformers, switching systems &c. would normally be used for each aerial system, a common phase detector, indicator and generator, may be used.
