Title: Improvements in the production of n-trisubstituted borazanes
Inventor: BROWN MICHAEL PETER
IPC: C07F5/00
Filed: 1962-02-08
Abstract: N-trisubstituted borazanes are made by reacting, preferably at or below room temperature, an alkali metal borohydride and a tertiary amine salt while they are maintained in suspension in a tertiary amine which is a liquid at the temperature employed and which contains also water.  The t-amine salt and borohydride are preferably suspended in equimolecular proportions in sufficient t-amine to give a workable suspension and then a little water, preferably 0.75 to 1.5 mole for each mole of borohydride is added with stirring and when the evolution of hydrogen ceases the mixture is filtered and the product separated by distillation or crystallisation. The t-amine salts are preferably those of strong acids such as hydrochloric, hydrobromic or sulphuric acid, and a t-amine R3N, where the R radicals are the same or different and are C1 to C20 alkyl groups, aryl groups or substituted or unsubstituted cycloalkyl groups in which the ring contains 5 to 7 carbon atoms or a heterocyclic tertiary amine in which the t-amino group is in the ring. The tertiary amine used as a dispersing medium may be of the type R3N or an heterocyclic amine as described above.  The amine dispersing medium may be different from that used in salt form, or a mixture of a more volatile and a less volatile amine may be used, the latter being less volatile than the amine whose salt is used. When the reaction ceases, the mixture is filtered and the filtrate is heated to effect transamination and to remove the more volatile amine by distillation.  Detailed examples are given.

Abstract: 563,398. Packaging machinery. ROSE, A. G., KAY, J. A., and ROSE BROS. (GAINSBOROUGH), Ltd. March 27, 1943, No. 4995. [Class 94 (i)] In a machine for gluing the outside flaps over the inner flaps of a fibreboard or like container, wherein means are provided for ensuring that those portions of the outside flaps which register with the gap between the inside flaps are not glued, such means comprise a feeler mechanism engaging the inner flaps during the passage of the container through the' machine. This feeler mechanism operates to put the gluing devices into operative position only during its engagement with the inside flaps and, as the feeler mechanism rides off the flaps, it operates to throw the gluing devices out of operation. The container 11 is moved through the machine by a conveyer 13 with its inside flaps folded inwards horizontally and its outside flaps folded outwards horizontally. A feeler 143 pivoted at 135 is urged by a spring 154 upwardly through a slot in a base-plate 141 to engage the lower inner flaps. Whilst in engagement therewith the feeler operates a switch 139 controlling a solenoid 136 which, through a toggle 131, moves a pivoted glue bath 106 so that the roller 104 therein contacts,the inner surface of the outside flaps. A pair of gluing devices is provided for the lower outside flaps and a pair for the upper outside flaps, and they are adjustably mounted so as to accommodate flaps or containers of varying sizes. When the feeler rides into the space between the lower inner flaps, the switch is operated to actuate the solenoids to move the gluing rollers out of engagement with the outside flaps. An additional feeler 149 projects through the slot in the base-plate 141 into a recess 152 therein. If the contents of the container sag into the gap between the lower inside flaps, they contact the additional feeler and, through a switch 138, the solenoids controlling the movement of the lower glue baths are operated to move the lower glue baths so that the rollers 104 therein move out of engagement with the outside flaps. Specifications 547,002 and 563,399 are referred to.

Filed: 1972-02-03
Abstract: 1341163 Temperature responsive actuating element LANDIS & GYR AG 3 Feb 1972 [12 Feb 1971] 5130/72 Heading G1D Thermal energy is converted to mechanical energy by a device wherein heat is applied to liquid in one or more annular chambers which is/are in communication with, but thermally insulated from, a further annular chamber so as to cause a volume expansion thereof, and hence a movement of an actuating rod attached thereto. In the embodiment shown, the device comprises annular chambers 9, 10, 2, chamber 2 being seated by spring bellows 6. Heating elements 11, 12 vaporize the liquid, preferably water, in chambers 9, 10 thereby causing contraction of the bellows 6 and hence movement of a rod 7. Use of only one of the elements 11, 12 moves the rod 7 by a half-stroke. In modifications, a single uniformly wound heating element is used Fig.1, (not shown), or a single asymmetrically wound element is used in combination with a chamber whose inner wall converges towards chamber 2, Fig.3, (not shown). This latter modification gives rise to a non-linear extension of the rod 7 with time.

Abstract: 1,144,891. Vehicle direction indicating apparatus. VENNER Ltd. 5 May, 1966 [5 Feb., 1965], No. 5131/65. Heading G4D. Depending on the direction of movement of e.g. a car, a pulse is received on first one of the leads 1, 2 (Fig. 1) and then on the other, the order in which the pulses come, determining whether a pulse is applied on lead 11a or 12a to increase or decrease by one the count in a counter, indicating e.g. the number of cars in a car park. In one embodiment, if a pulse from a buried loop at the entrance of a car park is first received on lead 1, a bi-stable device a is set, which in turn via an AND gate 5 sets a second bi-stable device b. When a pulse from a second loop is received on lead 2 the device b is reset and a pulse is applied to the counter. In a second embodiment, the second pulse is applied direct to the bi-stable device b to reset it, the bi-stable device b in turn setting a further store which remains in its "1 " state until reset by a scanning pulse. To prevent errors, a delay mechanism resets all the bi-stable devices if the second pulse does not arrive within a predetermined time.

Abstract: 857,666. Magnetic amplifiers. THOMSON PRODUCTS Inc. Feb. 15, 1957, No. 5290/57. Class 40 (9). [Also in Group XXXV] In an alternator speed-control arrangement, alternator 1, Fig. 3, driven by a turbine 2 through a gear-box 3 is speed-controlled by a tachometer 4 driven from the gear-box at a speed identical to that of the alternator, and load correction to give a voltage characteristic droop whereby load division is maintained when the alternators are worked in parallel is achieved by a current transformer 95, Fig. 2, applying a compensating signal to the output of a discriminator 5, to which the tachometer output is fed. The compensated error signal thus developed is amplified in a two-stage magnetic amplifier 6 to actuate a valve actuator 8 through a torque motor 7, the movement of core 85 generating a signal, in the windings 83, 84 which is fed back to winding 94 of amplifier 6a. The magnetic amplifiers are of the full-wave, self-saturating type and are controlled by the input to winding 41.

Abstract: 1,219,571. Welding by fusion. LLOYDS (BURTON) Ltd. 19 March, 1968 [3 Feb., 1967], No. 5295/67. Heading B3R. In an automatic welding machine for welding e.g. the V-groove formed between butted ends of tubes, the welding head is reciprocable with an amplitude which is controlled by a control means comprising a pair of limit devices 19, 20 actuable by an abutment 21, on or connected to the welding head, to reverse the action of a power-operated means 17 for reciprocating the head, and cam means actuable to separate the limit devices incrementally at the commencement of successive stages of the welding operation. Limit valves 19, 20 are mounted on bars 23, 24 movable in the direction of reciprocation of the head, the bars being spring-loaded towards one another but urged apart against this loading by the cam means which bear on rollers 38 on each bar. Five cam plates, e.g. cam plate 27, are provided, four of them being individually movable and the fifth and smallest (31) (Fig. 1, not shown) being fixed to define a distance of least separation of the bars 23, 24. As the tubes (12) being welded are rotated the welding head reciprocates in the V-groove to deposit a first layer of weld metal from a welding wire (11) between the work and which an arc is maintained. Upon completion of the first revolution of the tubes, a magnetic reed switch is actuated by a magnet (39) clipped to one tube, whereby a cylinder (32) connected to the next largest cam plate is actuated to increase the spacing between the bars 23, 24, whereby the amplitude of reciprocation of the head is increased. At the same time the speed of rotation of the tubes is decreased. A second layer of weld metal is then deposited. Successively larger cam plates and successively slower speeds of rotation of the tubes for each layer of weld metal deposited ensure that the V-groove is completely filled by the end of the operation. In another embodiment a single cam which is successively positioned in three predetermined positions is used, the cam being connected to a first pneumatic piston-and-cylinder unit, the cylinder of which is itself movable by a second such unit. In this case the cam shape is matched to the shape of the groove to be welded.
