Title: Bubble switching system

Filed: 1973-11-29
Abstract: 1452932 Magnetic storage arrangements MONSANTO CO 29 Nov 1973 [1 Dec 1972] 52321/75 Divided out of 1452931 Heading H3B A magnetic bubble switching arrangement includes a bi-stable circuit which in one state provides a series of bubbles and in the other state provides no bubbles. The presence of bubbles from the bi-stable causes bubbles only on a first path to be transferred to a third path, whereas the absence of bubbles from the bi-stable causes bubbles only on a second path to be transferred to the third path. In the absence of a bubble in delay loop 52 of the bi-stable a bubble on input d is transferred via field 50 and circulates via loop 52 and field 48, providing bubbles on track 56 which causes bubbles on the first path 60 to be annihilated at 64 and bubbles on the second path 66 to be transferred to the third path 72. If a further bubble now arrives at d the bubble in loop 52 no longer circulates and is annihilated at 54. The resulting absence of bubbles on track 56 allows bubbles on path 66 to pass to annihilator 70 and bubbles on path 60 to pass to path 72. The arrangement is used as a fetch-execute control in the bubble computer described in Specification 1,452,931.

The support 1 and the catch 2 are encircled by a spring 8 each end of which is connected to the support 1. At least one end of the spring 8 is connected by means 9 consisting of bars 10, 11, Fig. 3, which are held together by low-melting material "a" so that, when an electric current is passed through a wire 12, the material "a" is melted and the spring is released, the untwisting of the spring allowing disengagement of the support 1 and the catch 2 as shown in Fig. 9, so that unlocking of the element 5 is effected. If repeated unlocking of the element 5 is desired then the means 9 comprises a slot 14, Fig. 4, in the support I which receives an end of the spring 8 therein. The latter is removed from the slot 14 by electrical means 15 having a rod 16. In modifications a catch 17, Fig. 5, is positioned between parts 19 and 20 of the support, the part 19 having a cylindrical portion 21, and a catch 22, Fig. 7, is cylindrical, the support consisting of three parts 23, Fig. 8 and the external surface of the support being concave as shown in Fig. 7 in order to centrally locate the spring 8.

Abstract: 1497899 Air curtains SVENSKA FLAKTFABRIKEN AB 29 Dec 1975 [30 Dec 1974] 53006/75 Heading F4V A process for controlling the flow of ventilating-tempering (vt) air to a room in which a stream of vt-air is introduced into the room adjacent to a solid boundary of the room, comprises forming a sheet of moving control air generally parallel to but spaced inwardly of said room boundary to enclose at least a part of said vt-air stream between it and said boundary. As shown in Fig. 1, the stream of vt-air (solid lines 9) is introduced upwardly into the room through inlets 10 adjacent the window sill 14. The control air (dotted lines 8) enters the room via slits in nozzles 7 spaced from both the wall 4 and the ceiling 2, and flows in fannedout jet streams horizontally towards the wall 5 (see Fig. 2, not shown). The vt-air thus flows upwardly against the window 13 and across the ceiling between the surface of the ceiling and the control air flow from the nozzles 7. At the walls 3, 5 (and 6, not shown) the two stream of air become mixed and flow downwardly adjacent the walls and across the floor to outlets 11. A false ceiling 12 may be provided to assist the air flow. In another embodiment (Fig. 4, not shown), a box-like vt-air distributor 16 is located above the window, between the ceiling 2 and the jets 7. In further embodiments, the box-like distributor 16 is located centrally of the ceiling 2, with the nozzles 7 disposed beneath it. Additional vt-air may be introduced into the room via nozzles 10 which angle the air directly against the window 13 (see Figs. 6 and 7).

Abstract: 1413054 Electrophoretic coating compositions HOECHST AG 19 Nov 1973 [5 Dec 1972] 53544/73 Headings C3B C3P and C3R An acid, neutral or weakly alkaline aqueous thermosetting cathodic electrodeposition lacquer contains as binder, a polymerization or polycondensation resin, or a mixture thereof at least one resin component being present in the form of a nitrogenous base and/or being dissolved or dispersed in the water by means of a compound containing basic nitrogen. The compounds which are nitrogen bases are suitable as emulsifiers after neutralization with carboxylic acids or mineral acids. At east one resin is thermosetting and the proportion of free carboxyl groups is such that an acid number of 10 is not exceeded. The lacquers contain, as latent catalyst an ester of an aromatic mono- or poly-sulphonic acid or mono- or dicarboxylic acid. The amount of latent catalyst is such as to provide at least a 10% increase in the test hardness of the stored film according to DIN 53, 157. The composition may optionally contain an aminoplast and/or phenoplast and other adjuvants customary in electrodeposition. Examples relate to epoxy resin esters, polyester resins, e.g. an acid polyester of bis-2-hydroxypropyl)-ether of bisphenol A, neopentyl glycol and adipic acid reacted with 2-amino-2-ethylpropanediol-1,3, and acrylic resins containing OH groups. The compositions may be pigmented. Electrodeposition may take place, e.g. at 120 volts D.C., for 2 mins./30 ‹C. followed by stoving 20 mins./180‹ C.

Title: Circuit arrangements for commutatorless direct current motors

Abstract: 1435983 Rectifying; changing number of phases; motor control circuits NIXDORF COMPUTER AG 19 Nov 1973 [24 Nov 1972] 53587/73 Headings H2F and H2J A relatively smooth D.C. voltage is derived from the stator windings of a commutatorless having three or more phases, u1, u2 by combining in pairs the A.C. voltages of the phases which are adjacent in respect of their phase positions by means of a resistive or reactive summing circuit, R31, R41, adjusting the values of the A.C. voltages u1, u2 so as to provide adjusted values u1<SP>1</SP>, u2<SP>1</SP> of approximately the same amplitude as the combined voltages u1+u2. The combined voltages u1+u2 thus lie midway in phase between the pairs of the A.C. voltages so that the resulting rectified D.C. output has greatly reduced ripple. The Specification describes a speed control system for a commutatorless D.C. motor comprising four stator windings W1... W4 and a permanent magnet rotor. The rotor position is detected by Hall devices H1, H2 which provide quadrature sine waves which are amplified by transistors T1 ... T4 so as to provide a four-phase sine wave rotating field by currents in the stator windings W1 ... W4. The permanent magnet rotor induces a four-phase voltage in the stator windings W1 ... W4, the voltages induced in the pairs of stator windings which are adjacent in phase being combined by resistors such as R31, R41 and the values being reduced by resistors such as R21, R11 so as to provide an eight-phase signal for rectification by diodes D1, D2 which is fed to a speed-controlling system R. By comparison with a reference Ur, an appropriate energizing current is fed to the Hall devices H1, H2. The invention minimizes speed fluctuations due to inadequate smoothing of the speed-dependent signal and is applicable to positioning printing heads or producing step-bystep movement in magnetic tape devices. Expressions are given for the values of the summing and attenuating resistors, the ripple being further reduced by the effect of the variable internal resistance of the device.
