Abstract: 1,005,222. Transistor oscillators. NIPPON ELECTRIC CO. Ltd. May 25, 1962 [May 29, 1961], No. 20202/62. Heading H3T. An alternating-current generator comprises two oscillatory paths connected in parallel between input and output circuits and a feed-back loop containing a non-linear element connected between the input and output circuits, the arrangement being such that in the event of failure of one oscillatory path, the alteration in output level operates upon the non-linear element to alter the feed-back in such a direction as to tend to restore the output to its previous value. The oscillatory paths may be constituted by amplifiers Á 1 , Á 2 , as shown in Fig. 3, in which the feed-back path provides overall positive feed-back at a frequency determined by a frequency-sensitive circuit in the feed-back path thereby to sustain oscillations. Alternatively positive feed-back may be provided within each forward path, as shown in Fig. 6, comprising two oscillators, connected in parallel and synchronized by a circuit S, overall negative feedback being provided by the feed-back path including the non-linear element l. The feed-back path in the embodiment of Fig. 3 may be modified, Figs. 4(a)-(f) (not shown) to incorporate both positive and negative feed-back paths connected in parallel. One possible such arrangement employing transistor amplifiers is shown in Fig. 10, the non-linear element comprising two Zener diodes connected back-to-back connected in a negative feed-back path and the frequency-determining circuit F connected in a positive feed-back circuit. The inputs and outputs to the amplifiers are coupled through hybrid circuits H1, H2. Alternative non-linear elements which may be used are directly or indirectly heated thermistors or ballast tubes. Means similar to those described in Specification 977,946 may be provided to warn of the failure of one path by comparing the outputs of the two oscillatory paths and providing an indication if they differ substantially from equality, Figs. 11 and 12 (not shown).

Patent GB-979320-A (GB)
Title: Method of concentrating deuterium in natural water
IPC: C01B5/02
Filed: 1962-05-28
Abstract: <PICT:0979320/C1/1> In the method of concentrating deuterium in natural water using a " cold " tower 1 through which initial water descends in countercurrent to cooled and D-enriched H2S, a portion of the D-enriched H2O so produced flowing via a heatexchanger to a " hot " tower 3 through which D-impoverished reheated and humidified H2S from cold tower 1 is passed upwardly whereby the H2S is enriched in D and thereafter cooled and dried in drier tower 7 by direct contact with an ancillary cooling water circuit before reentry into the cold tower 1, that quantity of D-enriched water which is to be passed to the hot tower 3 is introduced into the ancillary cooling-circuit water stream at the top of drier 7, wherein it assists in the cooling of the Denriched H2S, and an equal quantity of the ancillary cooling-circuit water stream which has been heated by contact with the D-enriched H2S is removed at the bottom of drier 7 and led through a conventional heat exchanger 2 en route to hot tower 3.  The admission of the D-enriched water from cold tower 1 into the ancillary cooling circuit water stream reduces the quantity of water that must traverse heat-exchangers 8 and 9, which transfers its heat to an equal quantity of liquid from the circuit including H2S humidifier 6.  The remaining quantity of humidifier-circuit liquid is heated in heat-exchanger 11 by hot waste water from stripper 5 and heat exchanger 4, which recover dissolved residual H2S from the effluent liquid from hot tower 3, said H2S being recirculated to the bottom of hot tower 3.  In the main H2S circuit, from the top of cold tower 1, D-impoverished H2S passes upwardly in succession through humidifier 6, hot tower 3 wherein the H2S becomes enriched in D, drier-cooler 7, and finally cold tower 1, wherein the H2S becomes impoverished in D by isotopic exchange with the initial water.  The method described allows of a reduction in heat exchange surface area for a given consumption of energy.

Title: Improvement in machines for making the drawers or inners of match boxes
IPC: B31B13/34
Filed: 1928-07-16
Abstract: 294,933. Mellgren, G. E., and Sj÷str÷m, J. G. Aug. 1, 1927, [Convention date]. Machines for making boxes. In a machine, for making the drawers or inners of drawer-and-shell match boxes in which the sides of the! drawer are formed by winding a strip on to a rotary former 1 and are then pushed over on to a second former 2 to which the bottom is delivered and then joined to the sides, the completed drawer 3, when removed from the second former, is received by one or more removing members and carried thereby from the machine so that it retains a predetermined position. As shown, the drawer is removed from. the former 2 by an arm 9 rotatable on a pin 10 by gearing from the shaft 7 and formed with a thin tongue 18 which, as the former 2 is retracted by a spring 4 acting in conjunction with a cam 8 on the shaft 7, enters a groove 19 in the upper face of the former and supports the drawer which is removed from the former by contacting with a shoulder 17 on the arm. When the. drawer is free of the former 2 the arm is rotated to carry the drawer into a pivoted shoot 21 slotted to allow the upward movement of the arm; the drawer is thus placed in the horizontal portion of the shoot with its bottom directed upwards and as the arm is rotated backwards to its horizontal position, the shoot is rotated upwards about its pivot to allow the tongue 18 to return without removing the drawer from the shoot. Any defective boxes would not be caught by the, tongue 18 and consequently, in this arrangement, the removing- member also acts as a sorting-member. In another arrangement the removing-member is of Z-form and can be rotated so that the vertical limb enters a slot in an extended former and its lower horizontal limb engages under the lower side of the drawer as the former is retracted; when the drawer is free of the former the removing-member carries the drawer into a fixed shoot. In a further arrangement the removing- member is rotatable in a plane perpendicular to the direction of movement of the former and has an arm engaging beneath the drawer which is carried into a fixed shoot resting upon one of its longer sides. The Specification as open to inspection under Sect. 91 (3) (a) states that the removing-member may deposit the drawers upon a table &c. from which they are removed by another member or the drawers, when removed from the former, may be guided and allowed to fall below the former and afterwards removed by a separate, member. This subject-matter does not appear in the Specification as accepted.
