Title: Method and apparatus for bonding laminated glass
IPC: B32B17/10
Filed: 1959-11-23
Abstract: 924,441. Laminating. PITTSBURGH PLATE GLASS CO. Nov. 23, 1959 [Dec. 19, 1958], No. 39680/59. Class 140. [Also in Group XXX] A continuous process for removing air from between the sheets of curved laminated glass assemblies and effecting a bonding between the sheets comprises disposing the assemblies in an elongated series, embracing a narrow marginal portion of the outer surfaces of each assembly around its entire periphery only with an evacuating member; connecting each evacuating member with one of a plurality of poweroperated evacuating units; operating each evacuating unit to subject the evacuating member to a subatmospheric pressure; moving the series in its direction of extent to move each assembly along a path through a relatively hot atmosphere while so subjected to subatmospheric pressure; and moving the evacuating units through a relatively cool atmosphere in a direction parallel to the said path while operating each evacuating unit. As shown, assemblies 30 are carried by supports 22 (see Group XXX) and chains 10 running on rails 12 through an oven 16. Evacuating members 96 in the form of continuous loops of rubber of channel section embrace each assembly 30, and are connected by rubber tubing 94 and 95, the union 91 and pipes 46 and 47 with an evacuating unit 40. Pipes 46 and 47 are connected by a bar 90 carrying projections 101, over which the rubber tubing and channels may be draped when not in use. The units 40 are advanced above the ceiling 102 of the oven by means of rollers 42 running on rails 41. A slot (not shown) is provided in the ceiling of the oven, and is closed by two sets of spring- steel strips which are normally pressed against one another, but open sufficiently to permit passage of the pipes 46 and 47. A return path for the evacuating units 40 and channels 96 is provided between a station at which they are removed from assemblies 30 emerging from the oven and a station at which they are applied to assemblies entering the oven. The assemblies may be further heated after removal of the channel members. Each evacuating unit is propelled at the same speed as the assemblies 30 by a dog 53 on the chain 49 engaging a plate 54 on the unit. On the return run, the paths of the units 40 and the chain 49 diverge so that the dogs disengage, and the plates 54 are then engaged by dogs on another faster-moving chain (not shown). At the end of the return run this process is reversed. Specifications 819,179 and 924,442 are referred to. Reference has been directed by the Comptroller to Specification 829,586.

Title: Improvements in or relating to frequency stabilized optical masers
IPC: H01S3/139
Filed: 1962-10-25
Abstract: 1,019,295. Lasers. WESTERN ELECTRIC CO. Inc. Oct. 25, 1962 [Oct. 30, 1961], No. 40364/62. Heading H3B.  An optical maser using a material, such as helium neon mixture, with a non-homogeneously broadened emission line (attributable to the Doppler effect) and oscillating at three neighbouring frequencies has its frequency stabilized by beating the centre frequency with the two outer frequencies and using the frequency difference to control the resonant frequencies of the cavity. It is shown that the frequency of an emission differs slightly from the resonant frequency of the empty cavity by an amount which depends on the distance of the frequency from the centre of the Doppler broadened emission line of the maser material. Thus a feedback signal is produced whenever the centre frequency of the output differs from the centre of the emission line of the material. Fig. 2 shows the output from maser 10 passing through polarizers 13, 14 with polarizing axes at right angles so that at least one of photomultiplier tubes 15, 16 may detect the required two beat frequencies whatever the polarization of the output of the maser 10. The difference between the beat frequencies is then produced by mixer 18 and the frequency of the difference produces a voltage output from an F.M. discriminator 20. This voltage may be used to supply the coils 39 round magnetostrictive elements 36 which vary the length of the maser cavity (Fig. 3). Mirrors 31 are mounted on flanges 34 which are spaced by the magnetostrictive elements 36 which may be "Invar"  (Registered Trade Mark] if gaseous maser material is contained in a glass tube 37 connected to the flanges by metal bellows 38. Instead of varying the length of the cavity the voltage may be used to vary the refractive index of a cell placed in the cavity. The feedback arrangement may also be used to maintain a certain non-minimum voltage if the desired frequency is not the centre frequency of the maser material emission line.

A dobby-type patterning mechanism for operating the cams that control shedding in Specification 1160583 consists of oppositelyreciprocating draw knives 123, 125, with which vertical slides 30 can be selectively engaged. A perforated pattern strip 34 is sensed by needles 35, 36 to position one or other of hooks 43, 44 (one pair for each slide 30) in line with a pusher 45; the pusher is advanced by a vertical bar 58 acting through a roller 59' on a lever 60, the bar being depressed by a cam on the rotating part of the loom. When the pusher 45 displaces the hook 43, a roller 50 rocks the slide 30 so that its notch 117 engages the knife 123; when the hook 44 is displaced, a roller 55 rocks the slide into engagement with the knife 124. As the slide swings to engage a knife, a projection 31 on it comes out of a slot 106 in a rib 105 to release the slide for movement up or down with the knife. A pair of rods 101, 102 move apart to allow the slides to swing, and close in again at the end of a stroke to centralise them with their projections 31 in a locking slot. The knives 123, 124 are actuated by another cam-operated bar 108, through racks and pinions 113, 115, 117. Specifications 1160581, 1160582 and 1160584 are also referred to.

Abstract: 1,162,501. Gas blast switches. ENGLISH ELECTRIC CO. Ltd. and BRITISH INSULATED CALLENDER'S CABLES Ltd. 27 Sept., 1966 [27 Sept., 1965], No. 40947/65. Heading H1N. A device, for shorting out a capacitor connected in series with a power circuit for power factor correction if the current becomes excessive, comprises a spark gap 8, 9 in parallel with a switch 15, 24 inside a gas-filled chamber 1. The device is connected in parallel with the capacitor it protects and if the voltage drop across the capacitor becomes excessive, due to excess current, the spark gap breaks down. A relay responsive to the current in the circuit is energized by the excess current and operates a valve, not shown, to vent a passage 40 causing a movable contact assembly 23-26 to move to the right due to the gas pressure in the chamber 1 acting on its left-hand end. The contacts thus short out the spark; while passage 40 is vented, gas escapes from around a cylinder 31 through a one-way seal 35. When the current returns to normal the valve reconnects passage 40 to the high-pressure supply causing the contacts to be opened due to spring 30. Due to pressure on the seal 35 cylinder 31 is driven to the right to open ports 44 causing a blast of gas to pass through the hollow contact assembly. After a delay gas leakage past the seal 35 by a narrow bore 39 restored the cylinder 31 and the blast ceases. Cylinder 31, the contact assembly and chamber 1 have quartz or glass fibre liners 46, 47, 48. The spark gap electrodes have graphite tips. The valve may also be operated by an inverse time overcurrent relay to close the contacts even though the spark gap has not broken down or by another relay if the current falls below a predetermined value or by yet another if the pressure source fails.

A circuit for converting an "a out-of b" code into an "α out-of #" code, # < b, is characterized in that unless precisely a input pulses are applied to the circuit no output pulses are produced. As described input pulse combinations in a "3 out of 7" code are applied in true and inverse form by devices 11, 16, Fig. 4 to a first diode matrix D 1 , which results in one of the vertical conductors fa'ling in potential, which, in turn, causes a second matrix of diodes D 2  to apply a combination of " 2 out of 5" pulses on leads Ai to A 5  to an output device 13. Should a spurious pulse combination (one not containing precisely 3 pulses) be applied to the first diode matrix no output at all is produced so that a diode gate D 3  opens and gives an error indication via an amplifier 15.
