Title: Method of heat shrinking thermoplastic sleeve wraps of glass containers
IPC: B29C63/42
Filed: 1977-03-30
Abstract: 1524335 Heat shrinking sleeves on to articles OWENS-ILLINOIS Inc 30 March 1977 [31 March 1976] 13334/77 Heading B5A Thermoplastic sleeves are heat shrunk on to articles, such as bottles, by directing radiant heat first on to the central region of each sleeve to shrink that region on to the article, and then directing radiant heat on to the two outer regions of each sleeve, simultaneously or in succession, to shrink those regions on to the article. Heat shrinking of the outer regions occurs progressively from the central region outward. The process is carried out in apparatus comprising a first zone having a bank of gas fired adjustably mounted infra-red heaters directed at the central regions of the sleeve covered articles as they are conveyed through the zone and a second zone comprising upper and lower banks of similar heaters directed at the upper and lower regions of the articles. Located opposite both zones is an exhaust hood connected to a suction fan, the air drawn into the hood from the article conveying zone serving to help direct the heat correctly and to cool the chucks by which the articles are suspended from their conveyer. The chucks are rotated at a speed sufficient for the upper and lower regions of the sleeve to be centrifugally rigidified against sagging in the first zone. The apparatus is the subject of copending Specification 1,524,336, and the centrifugal rigidifying aspect is the subject of copending Specification 1,522,934.

Title: Improvements in and relating to electric arc machining apparatus
IPC: B23H1/02
Filed: 1955-05-09
Abstract: 788,366. Machining by spark discharge. ELOX CORPORATION OF MICHIGAN. May 9, 1955 [Oct. 1, 1954], No. 13358/55. Class 83 (4). Apparatus for machining a workpiece 10 by electric spark discharge between the workpiece and an electrode 12 comprises a condenser 16 across the spark gap, which is charged through a variable resistor whose resistance is varied automatically and means 82 for limiting the maximum voltage across the gap to a value substantially less than that of the power source. The resistor preferably comprises a triode 44 whose anode 42 is connected to a full-wave rectifier 28, fed from one secondary winding 24 of a supply transformer 18, and whose cathode 48 is connected to workpiece 10, condenser 16 and through a rectifier 82 with the centre tap of the secondary winding. The latter is connected at 86 to the output of a rectifier 26 fed from a further secondary winding 22. The grid 60 of triode 44 has a grid leak resistor 62 and is connected through condenser 64 with the anode 66 of a control triode 68 which anode is supplied with current through resistor 70. Grid 78 is connected to a voltage source 80 and cathode 72 is connected to workpiece 10 and network 74, 76 in parallel with condenser 16. When condenser 16 discharges across the gap, triode 68 is caused to conduct and the reduced voltage thereby produced on its anode acts on grid 60 to bias valve 44 to cut-off. Current flows from condenser 76 to condenser 16 and after a delay sufficient for the spark gap to become de-ionized, grid 78 becomes gradually more negative and reduces current flow through triode 68 thereby increasing the voltage on its anode and on the grid of triode 44 causing the latter to conduct and re-charge the condenser 16. A pair of separate transformers may be used instead of the windings 22, 24. In practice a bank of up to one thousand triodes 44 may be used to conduct the charging current, one control triode 68 being used for each fifty or sixty charging triodes. In another embodiment, Fig. 4 (not shown) the control triode 68 is omitted. Means may be provided for rendering triode 44 non- conductive if a short circuit occurs across the spark gap. A dielectric fluid is maintained in the spark gap which may be kept constant or the electrode may be vibrated.

Title: Improvements in or relating to double current telegraph installations
IPC: H04L25/20
Filed: 1935-05-10
Abstract: 442,192. Code telegraphy. NATIONALE TELEPHON - UND TELEGRAPHENWERKE GES., 136, Mainzerlandstrasse, Frankfort-on-Main, Germany. May 10, 1935, No. 13839. Convention date, May 19, 1934. [Class 40 (iii)] Relates to double-current telegraphy in which the spacing battery at the sending end is strong enough to reverse the line current by overpowering the marking battery at the receiving end during a spacing impulse. According to the invention the receiving relay is provided with a supplementary winding so connected in relation to the batteries that it eliminates the effect of bias when the receiver is used for monitoring at the sending end. During the transmission of a five-impulse character by station A the contact u is closed. If the transmitter makes contact at S, marking current goes from marking battery Br1 through the line, and through battery Br1<1> and sending- on relay Ea at the repeater station U, so that armature ea remains in the marking position as shown. When the transmitter breaks contact at S, however, the spacing battery Bal becomes effective and overpowers the repeater battery Br1<1> causing armature ea to connect battery Bu to line Lb and so to send on a signal to station B. The battery power has to be adjusted so as to compensate for line losses, and as a result the spacing signals are stronger than marking signals in coil l of the receiver at the sending end. In order therefore that this receiver may serve for monitoring purposes, a supplementary coil g is provided to neutralize this bias. The current strengths are adjusted by means of resistances Ra1 Rg1, Wa, Ru and the adjustments of Ra1 Rg1 may be coupled. The transmitters may have make-before-break switches K as has been shown in the case of station B, the cam switch V being of the kind described in Specification 389,999. Specification 442,278 also is referred to.

Title: Improvements in or relating to electric pulse lengthening circuits including transistors
Inventor: BARRY JOHN NORMAN
IPC: H03K9/02
Filed: 1958-05-01
Abstract: 855,376. Automatic exchange systems. GENERAL ELECTRIC CO. Ltd. April 29, 1959 [May 1, 1958], No. 13881/58. Class 40 (4). [Also in Group XL (c)] A pulse lengthening and rectifying circuit (Fig. 4) provides a D.C. output voltage for operating the calling or ringing circuits of a subscriber's line when pulses are received on an input line 20. These pulses are positive-going and each causes a capacitor 5 to charge so that at the end of the pulse the circuit comprising capacitor 5 and inductor 4 rings, the first negative half-cycle causing the transistor to conduct and to bottom. The ringing circuit is heavily damped by the input circuit of the transistor and the transistor accordingly remains conducting for a much longer period than the initial pulse. The output from a transformer 24 in the collector circuit is rectified at 27, 28 and provides a D.C. output so long as the input pulses continue to arrive. The bifilarly wound secondary winding 24c forms part of a neutralizing circuit 24c, 32. The decoupling resistor 25 in the collector circuit may be replaced by a relay which will also operate so long as the input pulses arrive. Fig. 5 shows a pulse demodulator circuit in which amplitude-modulated multiplex pulses derived from a telephone system are applied at terminal 35 together with gating pulses at terminal 41 so that a gating circuit 36, 38, 43 selects a desired channel. The selected channel pulses cause circuit 4, 5 to ring in the manner described but the collector circuit is connected to low-path filter 44 and the transistor is not allowed to bottom. Accordingly sawtooth-shaped waves are developed at the collector having an amplitude dependent upon the amplitude of the input pulse and these are passed through the filter and the windings 46a, 46b of a line hybrid transformer to provide the demodulated speech for the subscriber's line. Resistor 49 in the collector circuit may be replaced by a relay which will operate so long as input pulses arrive and so may provide ringing or other calling signals for the subscriber's line.
