Abstract: 1,095,454. Condensation of vapour; sprayproducers. DEUTSCHE GOLD UND SILBER SCHEIDEANSTALT. Aug. 16, 1966 [Aug. 21, 1965], No. 36648/66. Headings B1B and B2F. [Also in Division C1] Cyanuric chloride is obtained in finely-divided solid form by introducing cyanuric chloride vapour through pipe 122 into a vessel 201 into which is sprayed, through nozzle 113, a coolant liquid (e.g. methylene chloride or chloroform) which vaporizes while causing condensation of the cyanuric chloride vapour to finely-divided solid particles, a gaseous and/ or vaporous medium being fed to the contact surface between the cyanuric chloride vapour and cone of liquid coolant emerging from the nozzle. A stream of the gaseous and/or vaporous medium may also be introduced into the upper part 206 of vessel 201, and the medium then flows downwards through screen 207. The finely-divided solid cyanuric chloride collects at the base of vessel 201. Nitrogen or air may be used as gaseous medium, or the vapours of the volatilized liquid coolant may be used as vaporous medium. As shown in Figure 2, the gaseous medium is fed through pipe 116 to an annular pipe 114 surrounding the nozzle-pipe 111. The gaseous medium flows out through annular gap 117 onto the tip of the cone of liquid coolant emerging from nozzle 113. At its lower end, pipe 114 has a heated annular space 115. Pipe 111 is provided with thermal insulation 112. Pipes 122 and 118, for introducing cyanuric chloride vapour, is surrounded by a heating-jacket 119, 121 which is supplied with the same heating-liquid as annular space 115. The temperature inside vessel 201 is kept above the boiling point of the liquid coolant by metering the cyanuric chloride vapour, liquid coolant, and/or gaseous medium. The wall of the vessel may be heated by jacket 203. The vapour formed by evaporation of the liquid coolant flows from vessel 201 through pipe 209 into column 211 where the vapour is, at least partially, condensed by contact with downflowing cooled condensate which has been pumped into the top of the column through heat-exchanger 213. Part of the liquid coolant is conducted to nozzle 113 by pump 215. If the vapour of the coolant liquid is to be used as vaporous medium in vessel 201, the medium is transported into the vessel from the top of column 211 by fan 216. The cyanuric chloride vapour to be condensed may be in admixture with a carrier gas such as air or nitrogen.

Abstract: 1,252,076. Static rectifiers; voltage regulators; vehicle supply systems. ROBERT BOSCH G.m.b.H. 6 March, 1969 [7 March, 1968], No. 11857/69. Headings H2F and H2H. [Also in Division G3] A 3-phase bridge rectifier 8 to 13 (Fig. 1) coupling a vehicle engine driven alternator 1 to sundry load on the vehicle, is provided with Zener diodes 12, 13 in one arm to limit the voltage between lines 6, 7 to about 38 Volts. It is stated that excess voltage between these lines can occur when starter motor 20 is operated also when a load 18 is suddenly switched off causing the alternator voltage to rise e.g. to 250 V. if the battery 16 is disconnected. A regulator 21 is set to maintain the alternator voltage to 14 Volts but its response to sudden excess voltage is not sufficiently rapid to prevent damage to itself and other components. Additionally the rectifiers 10, 11 may be Zener diodes (Figs. 5a, 5b, not shown). Rectifiers 8, 10, 12 are mounted on one cooling plate and 9, 11, 13 on another, the plates also being conductors, Fig. 4 (not shown). Regulator.-The regulator 21 is connected to the output of a second bridge comprising rectifiers 23 and the rectifiers 9, 11, 13 and controls the energization of the alternator field winding 5, by means of transistor switches 33, 34, which conduct alternately at a switching cycle frequency of 10-100 c.p.s. When the alternator voltage is low the potential at point 27 in a voltage divider is low whereby a Zener diode 32 is blocked. Hence transistor 33 has no base current and is non-conductive. Its collector is therefore positive relative to lead 7 so that transistor 34 conducts and current flows in winding 5 increasing the alternator voltage. As the alternator voltage increases the potential at point 27 increases until eventually Zener diode 32 breaks down causing transistor 33 to conduct which renders transistor 34 non-conductive stopping the field current supply. Current will continue to flow in winding 5 briefly via diode 38. At least one of the dioes 23 may also be of Zener type (Fig.6, not shown).

[Also in Division A4] In a cabinet of the type having vertical object-supporting panels suspended from tracks and slidable between storage and exposed positions, releasable locking means for the panels is actuated by movement of a panel towards its exposed position to lock the other panels in their storage positions and released by movement of a panel towards a storage position. As shown, the cabinet comprises a frame 20, 21, 22 (23), 24 and 25 closed by a cover 26, sides 27, back 28 and a floor 29. A frame 30 connected to uprights 20 and which may be swung downwardly below the cabinet for transport purposes, carries slotted channels (33) each of which supports two sets of rollers 34 from which the panels 38 are suspended. The panels, which are of the "peg-board" type are provided with front flanged plates 40 which in the storage position form a front for the cabinet. In the storage position, each panel 38 seats against a rubber buffer 45 and is provided with a recess 46 to receive a locking bar 47, Fig. 7, pivotally supported at its ends on side frame members 22. The locking bar 47 is formed as a section 47A having oppositely directed flange sections 47B and 47C. A roller 50 inserted at the bottom edge of recess 46 tilts the bar 47 as a panel is withdrawn so that the section 47B lies in the path of a member 52 carried by each panel whereby the other panels are prevented from withdrawal until the withdrawn panel is returned to its storage position whereby its roller 50 tilts the bar 47 to its original position. Movement of the bar 47 to either position is assisted by a spring-loaded rocker (53), Figs 5 and 6 (not shown) associated with one end of the bar 47. All the panels are locked in a storage position by means of a handle 60 which incorporates a key-operated lock (61), Fig. 2 (not shown) and is mounted on a frame upright 20. The handle is connected through linkage (62)-(66), Fig. 3 (not shown) with a lever (67) carrying a roller (70) which engages a cage (71) welded to the bar 47 and by which the bar 47 may be turned to allow or prevent passage of a roller 50 on one of the panels.
