Title: Air-conditioning unit of the induction type
IPC: F24F1/01
Filed: 1962-08-07
Abstract: 944,790. Ventilating and air conditioning apparatus. DELL'ORTO CHIEREGATTI S.p.A. Aug. 7, 1962 [Aug. 14, 1961], No. 30206/62. Heading F4V. In an air heating and circulating unit of the induction type comprising a heat exchanger 1 forming a pervious lateral wall section of an air mixing chamber M, a plurality of rows of primary air nozzles 6, 7 open into the mixing chamber, the nozzles in each row which all extend parallel to the heat exchanger, being of the same height, the heights from row to row decreasing stepwise with increasing distance of the rows from the heat exchanger. Primary air enters through a plenum chamber 2 whence it flows through a silencing labyrinth 3 under the control of a valve 9 to the nozzles 3. The flows of air from the nozzles induce a flow of secondary air from the room through a front louvre 4 and through the heat exchanger into the mixing chamber whence it is discharged with the primary air through an upper louvre 5. Geometrical relationships for the heights of the nozzles from row to row to give maximum induction efficiency are described. In a modification a second heat exchanger is arranged to form the opposite wall of the unit and the heights of the nozzle rows decreases from both exchangers towards the central plane of the unit.

Title: Improvements in and relating to electric motor controllers
IPC: B60L15/04
Filed: 1930-10-09
Abstract: 364,198. Master control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Jones, B. W. ; 316, Glenwood Boulevard, and Fleming, W. J. ; 26, Henry Street, both in Schenectady, New York, U.S.A.) Oct. 9, 1930, No. 30266. Convention date, Oct. 9, 1929. [Class 38 (iii).] Field and armature control; non-regenerative braking.-In series parallel control of series motors, the fields are permanently in series and are arranged to be shunted by an inductance when the armatures are placed in parallel connection after running in series. Furthermore in stopping the motors, after running in parallel, by reversing the connections and connecting the armatures'in series excessive plugging voltage is prevented by maintaining the shunt about the fields until the motor speed is suitably reduced. When a master controller is moved to its first position in one direction, switches 17a .. 17d and 21a are closed to connect motor armatures 10 and 11 across the mains 15, 16 in series with their fields 12, 13, and resistances 22.. 25, 22a, 22b, 25a, 25b. Movement of the master controller to its second position closes a switch 27a to exclude the resistance 23. In the third position, provided a sufficient time has elapsed, switches 28a, 28b close to exclude resistances 22, 25, and thereafter, at time intervals, resistances 22a and 22b, 25a and 25b are excluded, and finally resistance 24 by the closure of a switch 31a. When the switch 31a closes, switches 28a, 28b, 29a, 29b, 30a, 30b, and 21a return to their normal open position. In the fourth position, switches 26a, 26b, and 38a close, and then the switch 31a opens, so that the armatures 10, 11 are connected in parallel, and the fields 12, 13 are still in series but shunted by an inductance 37 which has similar characteristics to those of the combined series fields. In the fifth position, provided a sufficient time has elapsed, the resistances 22, 22a, 22b, 25, 25a, 25b are removed in timed sequence. To stop the motors the master controller is moved to the opposite extreme position with the result that switches 18a .. 18d close, while the remaining switches return to their normal position shown, so that the motors are " plugged " with their armatures in series. When the switches 18a .. 18d close, however, the switch 38a is also closed, so that the shunt 37 is maintained. When the motor speed is suitably reduced a coil 39 is sufficiently energized to actuate a switch which opens the switch 38a, and thus removes the shunt 37.

Abstract: 783,892. Clutches. GYREACTA TRANSMISSIONS, Ltd. Oct. 18, 1955 [Oct. 25, 1954], No. 30738/54. Class 80 (2). [Also in Group XXXIV] An annular electro-magnetic clutch causes primary cam action of a series of balls between a pair of presser plates which themselves initiate secondary camming of a second series of balls to move the plates axially apart to engage two. friction clutch plates against two clutch friction surfaces. Two similar clutches A, B transmit a drive selectively from a shaft 1 to two shafts 28, 28a. Secured to the shaft 1 is a two-part annular casing 2, 3 having friction surfaces 4, 5, and secured between the parts 2, 3 is a ring 6 forming a cage for a series of balls 7 co-operating with conical recesses 9 in two presser plates 8, 10. The plates 8, 10 are located radially by pins 25 which allow slight circumferential movement, and are held axially by spring links 37a such as described in Specification 597,563, [Group XXXII]. Between the presser plates and the casing friction surfaces 4, 5 are two friction plates 32, 33 in driving connection with the shaft 28. An annular electromagnet 12 is supported from the presser plates by a threeeared flange 13 located for slight circumferential movement by pins 14 and having a series of caged balls in camming relation with the plates 8, 10. The armature 18 of the electromagnet is similarly supported by a flange 19 having balls 23 in camming relation with recesses 24. The magnet 12 and armature 18 are urged apart, when not energized, by springs 38, and have between them a clutch-plate 34 fixed for rotation with the shaft 28, the plate 34 carries friction pads 35 which can bear against a non- ferrous friction ring 36 backed by a heatinsulating marker 37. When the electromagnet 12 is energized, the friction plate 34 is clamped between the armature 18 and ring 36 to establish an initial connection between the shaft 28 and flanges 13, 19. This causes camming action by the balls 23 to separate the presser plates 8, 10 and initiate drive through plates 30, 31, the resultant torque on which causes cam action by the balls 7 to face the plates outwards to grip the plates 30, 31 against the friction surfaces 4, 5.

Title: Improvements in or relating to 1, 1, 2-trichlorethane and process of preparing the same
IPC: C07C17/04
Filed: 1946-10-16
Abstract: 1,1,2-Trichloroethane is prepared by adding one molecular proportion of chlorine to slightly more than one molecular proportion of vinyl chloride (e.g. 1.02 to 1.1 mols.) in the dark in the presence of at least 20 molecular proportions of 1,1,2-trichloroethane at a temperature of 20 DEG  to 60 DEG  C. and in the absence of any catalyst.  It is desirable to mix the chlorine with the vinyl chloride at the point of introduction in the trichloroethane.  Inert gases such as oxygen, hydrogen or nitrogen may be present and the process may be carried out either as a batch operation or in a continuous manner.  In the latter case the flow of trichloroethane is preferably counter-current to the flow of reagent gases, thus the trichloroethane may be introduced at the top of a gasabsorption tower and the mixture of vinyl chloride and chlorine near the middle or bottom of the tower which may be packed with Raschig rings, coke or activated carbon.  The product may be recirculated after cooling and in both the batch and continuous processes the product may be purified by washing with a dilute aqueous alkaline solution, and then dried by centrifuging or with a chemical drying agent, e.g. calcium chloride.  Alternatively, the product may be distilled directly. In an example of the batch process a mixture of vinyl chloride and chlorine are introduced into 1,1,2-trichloroethane at 20 DEG  C. and the temperature rises to 40 DEG  to 50 DEG  C.  The product is washed with dilute aqueous sodium bicarbonate solution and then distilled. Specification 341,781 and U.S.A.  Specifications 1,833,358, 1,833,393, and 1,944,306 are referred to.  The Specification as open to inspection under Sect. 91 is not restricted to the use of the specified molecular proportions of chlorine and vinyl chloride.  This subject-matter does not appear in the Specification as accepted.

[Class 61 (ii).] A hand-operated bolt or like cutting pliers has adjusting links for the jaws, pivoted to the jaws and handle levers, which engage through co-operating cam surfaces adjusting members housed in the handle levers and supported opposite the fulcrum point against downward thrust. The tool comprises handles 5, 6 pivoted at 7 having bifurcations in the upper ends to house adjusting sections 8, 9 to which are pivoted at 10 the jaws 1, 2 ; the adjusting sections rotatable about pins 12 are each shaped at the lower end to form a gear tooth 17 which engages a complementary rack recess 16 in a slidable plunger 15, also housed in the handle ; the plunger is threaded at one end 19 to engage a nut-headed sleeve piece 21 which is also threaded externally, the two threads are of different and opposite pitch, that in the plunger being the coarser so that a small movement of the sleeve effects a relatively greater movement of the adjusting section, which movement is further magnified by the pivot 10 being spaced at a greater radius from the pin 12 than the tooth 17. The end of the adjusting section may be made spherical instead of tooth-shaped, the corresponding engaging part of the plunger would then take the form of a rectangular slot. Stops 14 limit the movement of the jaws.
