Title: Improvements in methods of preparing halogenated hydrocarbons
IPC: C07C17/08
Filed: 1932-05-11
Abstract: The process described in the parent Specification, according to which halogen-butadienes and -butenes are prepared by addition of hydrogen halides to monovinylacetylene, is effected by passing gaseous monovinylacetylene into contact with a solution of hydrogen halide at a rate which is varied in accordance with the product desired, a higher rate of flow favouring the production of halogenbutadienes, and a lower rate favouring the production of halogen-butenes. Details are given of the selective manufacture of chloro-2-butadiene-1 : 3 or chlorobutenes, as required, by a process in which monovinylacetylene is circulated continuously through a system comprising a reaction vessel containing aqueous hydrochloric acid and a halide catalyst such as cuprous chloride, a condenser, a separator for separating the liquid reaction products from aqueous condensate, and a blower for returning unreacted monovinylacetylene to the reaction vessel, fresh acid and monovinylacetylene being added as required; a series of vessels containing acid at progressively decreasing concentration may replace the single reaction vessel.  The manufacture of bromo-2-butadiene-1 : 3 and bromobutenes in similar manner is referred to.

Title: Machine for covering objects with fluid coatings
Inventor: WOOKEY NORMAN
IPC: A23G3/24
Filed: 1960-04-21
Abstract: A machine for coating nuts or other objects <PICT:0921171/III/1> <PICT:0921171/III/2> with toffee or other viscous liquids, comprises a liquid toffee receptacle, a series of dipping members or forks 2 mounted for motion in a path wherein they entrain the nuts 2a, propel them through and lift them clear of the toffee, and heated take off fork means 8.  The nuts 2a (Provisional Drawing) are fed by a pusher plate 1 on to a grid 7 in a heated chamber lying within electrically heated portions 3 and 6.  Radial forks 2 mounted on a rotating frame cause the nuts 2a to pass through a pool of toffee in the thermostatically controlled lower portion 3.  The toffee level is controlled by a spade 15 and a tilting mercury switch 12 both mounted on a flexible arm 11 fixed to the centre shaft 5a of the rotating frame (see Group XXXV).  The coated nut 2b on reaching point 9 is lifted off the dipping fork 2, by an intermittently and non-uniformly rotating take-off fork 8 having electrically heated prongs and driven via a crank and slot drive. The take-off fork 8 on reaching the position shown, remains stationary for sufficiently long to allow the coated nut 2b to fall away on to one of a series of cooling plates 14 which are rotated while cooling.  This rotation is stopped, just prior to the removal of the coated nuts 2b by a scraper bar 16.  In an alternative embodiment the forks 2 are replaced by sprung arms 18 (Complete Drawing) with spikes 19, which arms are tensioned in turn by a detent 20.  When released by the retraction of the detent 20, the tensioned arm 18 drives the spikes 19 into the nut 2a resting on a support 21, which support is then retracted downwards.  The support 21 is V-shaped and is slotted, the slots coinciding with the spikes 19.  A scavenging row of forks without spikes 22, is constrained by guides so that the forks are moved radially outwards for most of their path thus nearly scraping the bottom of the dipping container and move back to their normal radial position before reaching the take-off position 9.  Means are provided to prevent the feeding of nuts to the support 21 when the scavenging row of forks arrive.  The transverse positions of the sprung arms are staggered between one row and the next, and the feed to each set of positions required is effected by a swivelling shoot.

Abstract: 703,473. Hydrodynamic torque converters. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. May 25, 1948 [Oct. 10, 1947], No. 14084/48. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 29, 1948.] Class 69 (2). (Also in Group XXIV] A hydrodynamic torque converter comprises a pump member, a turbine member having two or more blade rings, with the last blade ring of the turbine member arranged immediately preceding the pump blade ring and rotating in the same direction as the pump and disposed so that the outlet of the turbine blade ring lies at a greater radial distance from the axis of rotation than does the inlet of the pump blade ring, a reaction or guide vane member, means for disengaging the reaction member so as to permit its rotation in a direction opposite to that of the turbine and pump members and means for mechanically connecting the guide member to an output shaft through a reversing gear to provide an increase of starting torque. The object of the invention is to provide an improved converter which exhibits a high starting torque but which avoids having to race the engine to high speeds during starting. In Fig. 1 in a fixed casing 10 are arranged a pump member 14 with pump blades 16, a turbine comprising blade rings 20 and 24 and a reaction member comprising a blade ring 22. The outlet 32 of the turbine member is located at a greater radial distance from the axis of rotation than the inlet 30 of the pump. The shaft of the reaction member can be connected to the turbine shaft through a reversing gear or locked to the stationary casing. In a modification, Fig. 2, the pump 14 comprises a rotatable casing enclosing the turbine and reaction members. Transmission elements similar to those of the present converter unit are described in Specification 700,342 referred to. The reversing gear between the reaction member and the output shaft is constructed with a gear ratio adapted to increase the torque multiplication under double rotation conditions. Specification 703,517 also is referred to.

Abstract: 1412208 Automatic control of machine tools AEG-ELOTHERM GmbH and AKO-WERKE GmbH 23 March 1973 [30 March 1972] 14100/73 Heading G3N [Also in Division B3]  In a machine tool the position of a workpiece 6 on work-table 5 relative to a tool 4, e.g. a drill or an electrode is a spark erosion machine, is controllable in that the table is fed in a "positive" direction 25 normal to the tool feed path 9 by a servomotor 11 and feed screw 10 until a flat reference surface 27 on the workpiece contacts the tool to complete an electrical circuit including a D.C. source 16 and a signal passes along line 26 to a control device 15 whence it is transmitted to a servo unit 13 to stop the motor 11. The tool is now in the X-co-ordinate "setting-up" position 4' Fig. 2. A signal from the control device passes through line 28, direct control means 7 and feed unit 8 and retracts the tool and a signal is applied to input 29 to pre-set a pulse counter 21 to a count corresponding to the distance between the setting- up position and a desired reference position. A further starting signal to the control device causes unit 13 to again operate motor 11 in the positive direction 25 and pulses generated by device 12 linked to the feed screw cause pulse counter 21 to count-down from its pre-set value. The traverse may be rapid at first then reduced in speed when the count-down reaches a given figure at which the counter 21 generates an appropriate signal. When the count reaches zero it generates another signal to stop the motor 11. The tool is now in reference position 4 . This may be repeated for the Y- co-ordinate. Any desired working position may now be reached from this reference position by setting the particular pulse counters in the conventional manner. In order to exclude the effects of backlash in the feed screw a subsidiary circuit 30 Fig. 3 in the control device 15 may be provided and includes an erasable store 31, a comparator 33, a pair of bi-stable multi-vibrators 35, 42 and an AND-gate, which ensures that on returning to the reference position in the negative direction the motor 11 is reversed and changed to creep speed as the worktable passes the position and the table stops at that position while traversing in the positive direction.
