Title: Junction box
IPC: H02G3/16
Filed: 1973-02-21
Abstract: 1390174 Junction boxes THOMAS & BETTS CORP 21 Feb 1973 [21 March 1972] 8503/73 Heading H2E An electrical junction box made of insulating material comprises a base member 22 having inward ribs 52, 54 defining a recess 56, hinged at a portion 59 to a planar member 24 bearing contacts 90 disposed to engage in the recess 56. Each contact 90 has an upstanding arm 92 with slots 98, 100 bounded by sharp edges for piercing the insulation of a conductor 80, 82, 84 or 86 of a first cable 30 and thereby making contact, and resilient arms 108 biased against the planar member 24 for contacting a spade terminal 116, 118, 120 or 122 attached to a second cable 28. The piercing of the insulation on the conductors of the first cable 30 is assisted by folding the planar member 24 into engagement with the base member 22, causing the ribs 52, 54 to press the conductors into the slots 98 or 100. The planar member 24 is then fastened to the base member 22 by a latch 114 which engages a latch button 112. Strain relief for the first cable 30 is provided by posts 88, and by recesses 93 into which the ends of the conductors are introduced after passing over the upstanding arms 92 of the contacts 90. A dust cover 26, hinged to the base member 22 at the end opposite the planar member 24, is fastened by a latch engageable in a receiver portion 42. The junction box may be mounted by an adhesive layer applied to the underside of the base member 22 or by holes 38 therein.

Abstract: 1519383 Electric coupling TELEFONAKTIEBOLAGET L M ERICSSON 3 March 1976 [13 March 1975] 08580/76 Heading H2E A cable clip has a slot 3 for receiving a core of a cable, an opening 2 with converging sides which join the sides of the slot and one or more pairs of opposed teeth 5 on the sides of the opening which cut into the insulation of the cable so that the core may contact the sides of the slot. The teeth may be square cornered, or pointed as shown, angles A and B being about 60 and 10 degrees respectively it being found that with these angles, insertion of the cable does not tend to force the slot open. The clip may be a flat metal plate as shown, or U-shaped with openings and slots cut in each arm from the base of the U (Figs, 3, 4, not shown). The slot in one arm of the U may be narrower than that in the other to accommodate a range of core sizes. A double clip may be formed, having two sets of slots and openings side by side in a U- shaped plate and the slots in one arm may be longer than those in the other arm so that the cable is truncated at the shorter slit when pushed into the clip by a U-shaped tool of suitable size.

Title: Improvements in the manufacture of synthetic linear polyamides and apparatus therefor
IPC: C08G69/28
Filed: 1949-04-01
Abstract: <PICT:0674954/IV (a)/1> Linear polyamides are prepared by passing an aqueous solution of a diamine dibasic carboxylic acid salt at the requisite temperature and pressure through a first reaction zone in which the major portion of the salt is polymerized with removal of steam, then passing the resulting reaction mass through a second reaction zone in which polymerization is substantially completed, this zone comprising a tube which increases in diameter in the direction of flow and in which water is progressively vaporized and the pressure progressively reduced to substantially atmospheric by fluid friction in the tube, sufficient heat being supplied to the tube to prevent cooling below the melting point of the reaction mass, and finally passing the polyamide composition through a third zone at substantially atmopheric pressure where polymerization is completed and separation of the polymer and steam occurs.  As described, the first zone is an autoclave 2, operating at 230 DEG  C. and 250 lb. pressure from which the partially reacted mass passes to the second zone 4 comprising a tube heated by "Dowtherm" introduced at 8 DEG  to 290 DEG  C., the tube comprising three sections the lengths of which are in the ratio 2 : 1 : 1 and the diameters in the ratio 1 : 2 : 3. The third zone or finisher 5 is heated to a 275 DEG  C., steam being released at 10 and molten polymer being drawn off at 7 at about 8 lb. per hour, the residence time in the finisher being about 1 hour.  The process may be a batch one or continuous.  Specifications 461,236 and 461,237, and U.S.A. Specification 2,361,717 are referred to.ALSO:<PICT:0674954/III/1> Linear polyamides are prepared by heating an aqueous solution of diamine dibasic carboxylic acid salt at the requisite temperature and pressure (e.g. 230 DEG C, 250 p.s.i.) in an autoclave 2 in which the major part of the salt is polymerized with removal of steam, passing the resulting reaction mass through a tube 4, heated by a "Dowtherm" jacket, in which polymerization is substantially completed, the tube increasing in diameter in the direction of flow and water being progressively vaporized as the pressure is reduced to substantially atmospheric by fluid friction in the tube, and finally passing the polyamide composition through a heated third zone 5, at substantially atmospheric pressure, where polymerization is completed and separation of the polyamide and steam (drawn off at 10) occurs.

Title: Rental locker system
IPC: G07F5/20
Filed: 1973-02-23
Abstract: 1406779 Rental locker GLORY KOGYO KK 23 Feb 1973 [24 Feb 1972] 8962/73 Heading G4V A rental locker of the type rendered lockable by a key on the deposition of a number of coins includes means 2 for detecting inserted coins, means 20 for indicating the number of coins required and means for adjusting the number of coins required. In the embodiment described movement of a latch 29 to a door locking position by rotation of a key in cylinder lock 31 is normally prevented by a control lever 25 acting on blocking lever 30. The control lever 25 is moved to a releasing position by a flange 15 on a sliding plate 8 when the plate has descended to its lowest extent, the coin detecting lever 2 co-operating with rack teeth 13 on the plate to lower it one step on each coin insertion. A flange 14 on the lower end of plate 8 bears on one end of a lever 16, the other end of which supports the coin indicating plate 20. The number of coins required for each rental period is adjusted by selective engagement of a pin 42, positionable in lever 16 at various locations, with one of holes 43, 44, 45 in a sliding setting plate 46 (the holes 43, 44 and 45 corresponding to 1, 2 and 3 coins respectively) and manually raising plate 8 until the first, second or third tooth 13 is engaged by detecting lever 2. When the key is used to re-open the locker during the normal rental period a motor (53) controlled by a circuit including switches 37, 41 and 55 (see Fig. 4, not shown) operates to rotate a cam 52 counterclockwise, a pin 51 carried by the cam acts on a tooth 50a to raise the setting plate one step, and hence raise the plate 8 one, two or three steps according to the position of pin 42. The plate 8 is then appropriately set for another hiring operation. A timer switch (65) is operated at the end of the normal rental period (i.e. a specified time of day, or a fixed time after the locker was locked) to rotate cam 52 and hence raise the plate 8 one, two or three steps depending on the setting of pin 42. A further number of coins, as indicated by plate 20, must therefore be deposited before the locker can be unlocked. Coin discharge.-The coins inserted are temporarily stored in a face-to-face stack in tube 56 the bottom of which is normally closed by pivoted flap 57. The flap is swung open on rotation of cam 52 via a lever 63.

Title: Method and apparatus for testing luminescent materials
IPC: G01J3/443
Filed: 1974-02-28
Abstract: 1454013 Apparatus for testing luminescent materials INTERNATIONAL BUSINESS MACHINES CORP 28 Feb 1974 [20 March 1973]  9040/74 Heading G1A A method of testing a luminescent substance comprising measuring the luminous intensity at successively scanned areas theron using a monochromatic detector, deriving a steady signal representing luminous intensity, I, of each area, oscillating the detection wavelength while measuring luminous intensity, deriving a signal representing dI/d# for each area and plotting intensity and/or wavelength against position. The centre detection wavelength is simultaneously adjusted to make dI/d# zero to determine the peak intensity at all positions on the material. Fig. 1 shows light emitting diode wafer 2 on test stand 4, excited by laser 8 and its radiation detected by mono-chromator 10, whose wavelength is modulated through ## by   wobbler 12 at frequency W/211 and whose output is given by I = a 1  + a 2  ## sin wt. where a 1  and a 2  are constants. For small values of ## a 1  = I and a 2  =dI/dx, thus corresponding signals for a 1  and a2 ##, which are proportional to I and dI/d# respectively are obtained by photo-multiplier 14. The D.C. signal is applied to recorder 16 recording intensity against location and the A.C. signal via amplifiers 18 and 22 to cause servomotor 20 to adjust the monochromator so that the mean output wavelength corresponds to the peak intensity for each location. The wavelength of the peak intensity, using a known relationship may be used to determine the atomic proportion as x in In 1-x  Ga x  P. Curves of peak intensity and its wavelength plotted against position are used for example for a light emitting diode having regions diffused by zinc, where the intensity is high and the wavelength low. A variety of parameters relating to peak intensity and its wavelength may be used for evaluating luminescent material. The average wavelength of peak intensity may be obtained by first focusing the light from the whole sample surface to a small spot on a diffuser plate. Then with the servo off the monochromator may scan about this average wavelength. From this a function related to the standard deviation may be read by an A.C. R.M.S. voltmeter. The line shape may be determined in terms of its width and the skewness of its peak.
