Title: Improvements in or relating to fume cupboards
IPC: B08B15/02
Filed: 1960-06-14
Abstract: 1,002,297. Confining and removing fumes on generation. H. G. F. JENNINGS. Sept. 13, 1961 [June 14, 1960], No. 20843/60. Heading F4X. In a fume cupboard maintained at slightly less than ambient pressure by an extractor fan (not shown) drawing off from the operating shoot 9 via horizontal rear wall slots-21 and a duct 17, ingress of air to the chamber entry 31 is prevented or minimized by a gas curtain issuing through slots 39, 41 supplied by a fan (not shown) directly and via hollow chamber side walls respectively. This flow is preferably adjustable, e.g. by a damper in the fan inlet or outlet. The gas may be air or a gas which maintains an inert or reducing atmosphere in the chamber. As shown, the entry 31 has a sliding door 33 and the supply fan is energized before the door is opened. An alternative embodiment comprises a hollow door frame 61, Fig. 4, to be fitted against the outside of the front wall of the cupboard. Air is supplied through an inlet 89 and orifices 65 to two guides 63 and through two orifices 69 in the lower part of the frame to a lower guide 67, which is partitioned at 73, and is discharged through slots 83 and 87 across the opening. A sliding door 91, Fig. 5, comprises a frame 92 and air scoops 101 which fit into the slots 83. The door prevents outflow of air through the upper part of the slots 83 by means of the frame 92, and air which flows into the upper part of the guides is guided by the scoops 101 into a horizontal partitioned air duct 95 in the door, which discharges through a slot 99 to complete, with the previous discharge, a gas curtain across the door opening.

Patent GB-916387-A (GB)
Title: Improved process and apparatus for rendering non-adherent plastic surfaces adherent
Inventor: TRAVER GEORGE WHITE
IPC: B29C59/10
Filed: 1959-06-17
Abstract: In a process for treating a plastic body without the formation of ozone to render a surface thereof receptive to adhesives, floc and decorative material, such as ink, pigments, coatings and colouring matter, the surface to be treated is exposed to an electrical discharge in a gas atmosphere between spaced electrodes wherein the gas atmosphere is simultaneously ionized by an external source of ionization for the gas other than the electrical discharge.  As shown, polyethylene film 51 is passed around a driven roller 50 of metal or other conducting material covered with a dielectric film 59, e.g. of polyethylene, styrene, or glass.  A gas manifold directs a flame 56 against baffle 57 which guides ionized products of combustion between the <PICT:0916387/IV(a)/1> film 51 and a wire mesh electrode 58, thereby providing an ionized path for an electron flow between the electrode 58 and the film 51.  Alternatively, or in addition, ultra-violet lamps 60 provide the ionized path.  As a further alternative, the ionization of the gas about the film 51 may be effected by radiation from radioactive material.

Patent GB-210826-A (GB)
Abstract: 210,826. Automatic Telephone Manufacturing Co., Ltd., (Automatic Electric Co.). Oct. 12, 1922. Addition to 179,930. Automatic exchange systems.-In a trunking system employing twowire trunks, a preliminary earth is placed on the test terminal of a seized trunk and is replaced by a permanent earth when current is fed back over the speaking conductors from the distant exchange. If the trunk is defective, the preliminary earth remains to render the trunk non-selectable. and an alarm is given to the exchange attendant, as in the parent Specification. An alternative path is closed across the speaking conductors so that the alarm cannot be given in the case of a sound trunk by the opening of the subscriber's loop. First arrangement, Fig. 1. The rotary line switch C seizes a trunk X extending directly to a selector at the distant exchange, and having apparatus D associated therewith. When the switching relay 14 energizes and earths the test wiper 23, relay 41 energizes, earthing the test terminal 26 at armature 45, connecting up the alarm relay 51, and bridging a resistance 40 across the trunk. The line relay at the selector at the distant exchange and relay 43 energize in series, operating release relay 43, which open-circuits relay 41 and earths the test terminal at armature 47, and the alarm relay falls back. If the trunk is defective, relay 41 remains energized and the alarm relay operates a buzzer B and lights a lamp L. The line relay at the selector at the distant exchange is earthed through the tone machine transformer, so that dialling tone is sent back as soon as the shunt resistance 40 is removed. The relapse of relay 43 unlocks the line switch upon release. Second arrangement, Fig. 4. The plunger-type switch C<3> seizes a trunk X<2> having associated apparatus D<2>. When the plunger springs 330- 333 are operated, relay 351 energizes over its lower winding in series with the holding winding 317 (whence the line relay 314 need not be slowacting), locking itself, connecting up the alarm relay 364 and bridging a resistance 866 across the trunk. If the trunk is sound, relay 353 energizes and operates relays 352, 350 in parallel unlocking relay 351 and applying direct earth to the test terminal 335 at armature 360 in place of that through the lower winding of relay 351. A modification is described in which no bridge is placed across the trunk, and the release relay energizes a relay to remove the preliminary earth and open the alarm circuit.

Patent GB-1061874-A (GB)
Title: Heat-treatment of steel
IPC: C21D1/18
Filed: 1965-05-19
Abstract: A hypereutectoid steel containing less than 5% in total of alloying elements is heated in the range 1700-2000 DEG F. to form austenite and to dissolve therein substantially all carbides, and is then quenched to produce martensite and retained austenite.  It is then heated e.g. at 600-800 DEG F. to transform the austenite to bainite and the martensite to ferrite and carbides, after which it is rapidly heated to 1425-1525 DEG F. to convert ferrite to austenite and to disperse undissolved carbides followed by cooling to harden the steel. The latter step may include austempering or martempering, and tempering may follow.

Patent GB-1168854-A (GB)
Title: A Method of Echo Ranging and Recording and an Apparatus for Performing such a Method
Inventor: RICHARD JOSEPH DONAT
IPC: G01S15/14
Filed: 1967-05-08
Abstract: 1,168,854. Echo ranging. J. D. RICHARD. 8 May, 1967, No. 21374/67. Heading H4D. In an echo-ranging system the echo signals intensity modulate the beam of a cathode-ray tube (C.R.T.) whose faceplate incorporates a luminescent phosphor and a fibre optics matrix, and a photo-sensitive paper strip is moved across the faceplate to provide a graphic record of the echoes. In the Fig. 7 embodiment for marine use, the repetition frequency of pulse generator 96 is set proportional to the local speed of sound in water and frequency dividers 97, 98 provide range marker pulses corresponding to 100-fathom intervals (4 p.p.s.) and 10-fathom intervals (40 p.p.s.). Bi-stable circuits 82, 84 control gate 81 to pass two of the 4 p.p.s. pulses to open gate 72 and so cause a pair of acoustic pulses to be transmitted. The sea-bed echo of the first acoustic pulse triggers monostable 78 which opens gate 79 for a time sufficient to pass two of the 4 p.p.s. pulses to C.R.T. sweep trigger 88, so that the C.R.T. saw-tooth sweep is started by the first of the 4 p.p.s. pulses and stopped by the second, i.e. the sweep interval corresponds to 100 fathoms. In this interval the 10-fathom marker pulses and the echoes of the second acoustic pulse intensity modulate the C.R.T. beam to illuminate phosphor 93. The photo-sensitive paper strip is drawn past fibre optics matrix 92 set in C.R.T. faceplate 91 and the recorded image may be heat-developed. A gate 87, opened by the first transmitted acoustic pulse and closed by its sea-bed echo, passes the 4 p.p.s. pulses to a counter/printer 90, so that the depth of the sea-bed and fish shoals above are indicated by the counter reading (in hundreds of fathoms) plus the " vernier " distance along the displayed C.R.T. time-base. The speed of movement of the paper over faceplate 91 may be made proportional to the speed of a ship carrying the echo-ranging apparatus and may control the repetition period of the echoranging cycle. The recorded echoes can be displayed by positioning a luminescent panel behind the (translucent) paper strip (Fig. 5, not shown). In a modification the C.R.T. sweep is initiated by the sea-bed echo of the first transmitted acoustic pulse and stopped by the sea-bed echo of the second. In a second embodiment (Fig. 1, not shown) a single acoustic pulse, rather than a pair, is transmitted in each echo-ranging cycle and the C.R.T. sweep is started by the transmission (with or without a delay) and lasts a predetermined time. For echo-ranging in the atmosphere or space, electromagnetic energy is transmitted instead of acoustic energy. In an embodiment (not shown) for recording the depth of reflecting objects (e.g. fish) within the sea from an aircraft the energy source is a laser generating pulses in the green portion of the spectrum and the C.R.T. sweep is triggered by the energy reflected from the sea surface to give a recording referenced to the sea surface.
