Abstract: 353,427. Stencilling- apparatus. HœBL, F., 2107, Finkenh³bel, Warnsdorf, Czecho -Slovakia. March 11, 1930, No. 7969. Convention date, March 13, 1929. [Class 100 (ii).] The Specification as open to inspection under Sect. 91 (3) (a) comprises stencilling-apparatus constructed as follows. A spraying nozzle 34, Fig. 2 (Cancelled), is carried by an arm 3 pivoted at 5 to an arm 2 fixed to a pivot pin 6 to which is keyed a gear segment 8 engaging a worm 8<1> loosely mounted on a shaft 12 and adapted to be coupled thereto by means of a claw coupling 12m. The arm 3 is also pivoted at 26 to a rod 24 connected a b 25 to a gear segment 9 loosely mounted on the pin 6 and engaging a worm 9<1>, Fig. 5 (Cancelled), aiapted to be coupled to a shaft 13 by a coupling 9m. A sleeve 20 keyed on the shaft 12 is movable to couple the shaft to either of two gears 15, 18 rotating in opposite directions, and the shaft 13 similarly has a sleeve 20a adapted to be coupled to either of two gears 15a, 13a, the gear 15 being driven by a motor 22 and driving the gear 15a, which, through bevel gears 21, 21a, drives the gear 18a,. which, in turn, drives the gear 18. The arms 2, 3 are connected by rods r, r<1> to slides 35, 36 mounted in guide-plates 39, 40, each slide carrying a pencil resting on a record band 43 unwinding from a spool 44 on to a spool 45. After disengaging the couplings 9m, 12m, the nozzle 34 is moved by hand over the stencil 1, the separate movements of the arms 2, 3 being recorded by pencil lines K, K<1> on the band 43. The pencil lines are cut to form slots, the couplings are reengaged, and the pencils are replaced by electrical feelers 41, each comprising two contacts and a central contact pin, the latter engaging the slot and being engaged with one or the other of the contacts according to the slope of the curve, so that one or the other of two electromagnets 30, 31 is excited and attracts an arm 27 adapted to throw over the sleeve 20 or 20a and so to rotate the shafts 12, 13 and actuate the arms 2, 3. Consequent on this movement of the arms, the rods r, r<1> move the slides 35, 36 until the contact pin is in a neutral position between the contacts. A separate slot may be provided in the band 43 to control an electromagnet for opening the nozzle only when the latter is above a stencil opening. The above subject-matter does not appear in the Specification as accepted.

Patent GB-434886-A (GB)
Title: Improvements in or relating to methods and apparatus for drying solid sub-divided materials
IPC: F26B3/30
Filed: 1934-03-15
Abstract: <PICT:0434886/III/1> In the drying of wet clay and like pastes of finely divided material which are substantially refractory at the drying temperature employed, by passing the material through a heating zone as a thin deposit upon a conveyer, the material is heated mainly by radiant heat from surfaces heated to incandescene. A conveyer 1 comprising a band of wire mesh is fed continuously through a deposition hopper 5 into firstly, a pre-drying zone 19 and secondly, a drying zone proper 20, the latter being heated by oil or gas fired burners 21 playing flame into the spaces between the conveyer and raising pairs of refractory surfaces 22--23, 24--25 to incandescence, and the former being heated by combustion gases produced in the main heating zone.  From the heating zones, the conveyer passes through a collecting hopper 8 which receives the dried material from the conveyer, detachment from which is facilitated by flexing the band by rollers 6, 7 and by a rotary wire brush 9 and stationary wire brushes 10.  The heating zones and collecting hopper are enclosed from the external atmosphere and the conveyer returns to the latter through a dust seal 13. The drying zones may be heated by electrical means.  The direction of travel of the conveyer may be reversed, the pre-drying zone being lowermost in the apparatus; the heating zones may also be inclined or horizontal. The feed hopper 5 depends into a secondary hopper 60 provided with false walls 36, 39 which may be adjusted to vary the width of the outlet therefrom.  The material flows from the hopper 60 into the pinch between two feed rollers 32, 33 disposed on either side of the conveyer, a pair of doctors 34, 35 preventing adherence of the material to the feed rollers. The false inclined wall 39 may be vibrated by a rocker 40 driven by a chain and sprocket 41.  The material may be conveyed through two main heating zones separated by an intervening auxiliary drying zone.

Title: Improvements in or relating to heavy duty circuit-breakers
IPC: H01H33/12
Filed: 1932-03-19
Abstract: 396,488. Heavy - current switches. ASTBURY, H., Coval Avenue, Chelmsford, and CROMPTON PARKINSON, Ltd., Netherfield Works, Guiseley, near Leeds. March 19, 1932, No. 8229. [Class 3 (v).] Arc-rupturing devices.-The movable member 11 has pivoted to it a pair of bell cranks 13, 13a which are biased by springs 17, 17a so that their depending arms tend to move away from one another. Contacts 21, 21a are pivoted to the levers and biased downwardly and outwardly by springs 23, 23a. The arms 15, 15a of the levers carry contacts 31, 31a which co- 'operate with pivoted contacts 9, 9a that are biased downwardly by springs 37, 37a. When the member 11 is lowered to open circuit, the levers 13, 13a move away from one another and the contacts 21, 21a roll on one another and finally separate at the surfaces 27, 27a, the upper contacts still remaining in engagement at their outer ends, as shown in Fig. 2. Further downward movement of member 11 causes the latter contacts to separate in clean oil, thus providing three breaks in series. A barrier 41 on the member 11 causes a stream of oil to be driven by the pressure set up at the lower break towards the lateral breaks, whereas the movement of the lower contacts carries the arc formed thereat into clean oil. The load current may be carried by main contacts located on the member 11 and insulators and connected in parallel with the contacts shown. The Provisional Specification states also that the invention is applicable to airbreak switches.

Title: Improvements in internal combustion engines supercharged by means of a turbo-blower
IPC: F02D23/02
Filed: 1962-03-05
Abstract: 992,125. Regulating and charging I.C. engines; gas turbine plant; power plant; centrifugal blowers. R. POUIT. March 5, 1962 [March 11, 1961], No. 8449/62. Headings F1B, F1C, F1G and F1Q. In a diesel engine in which a by-pass conduit 8, Fig. 1, connects a blower delivery conduit 6 to the intake conduit 4 of a turbine 3, the ratio of the fuel quantity injected before inner dead centre to the fuel quantity injected after inner dead centre is reduced as the supercharging pressure increases and vice versa. Pedal 14 moves rods 15 and 17 in the direction of arrow to increase fuel injection before the inner dead centre by a camshaft-driven pump 11 1  until arm 16 1  engages cam 21 whereupon movement of rod 18 increases fuel injection after the inner dead centre by a pump 11 2 . Lever 30 acts through a chain drive 31 on fork 32, lever 33 and cam 21 and also on a valve 9 which progressively bypasses supercharging air to the turbine intake. For prestarting of the turbine or during slow running of the engine fuel may be injected in chamber 22. An excess pressure discharge valve 34 may be provided. A free wheel 25 and speedreducing gear 26 between turbine shaft 23 and engine shaft 24 increases the delivery torque when a low engine speed is combined with a high turbine speed. The compression ratio of the blower 2 is varied by means of chain 31, Fig. 3, which rotates toothed wheel 45, lever 46, swivel joint 47, and annular member 44 to incline blades 40 which are connected to fixed stator 42 thus varying the angle at which air enters the rotor 2a.

Abstract: 101,608. O'Donnell, J. P., and Knox, H. S. June 17, 1916. Addition to 8328/15. Hand-levers and handgearing, interlocking.- Electrically controlled locks of the kind claimed in the parent Specification are fitted with means for ensuring that the lever must be fully replaced to the danger position with the catch bolt down before it can be again pulled to the safety position. Fig. 1 shows an electro-mechanical device, and Fig. 2 a mechanical device. In the apparatus shown in Fig .1, contacts 44 in the circuit of the lock magnet 12 are normally closed by the lever 42. When the signal lever is pulled off, a pin 49 on the tappet 5 rocks the lever 42 at the completion of the stroke, and breaks the circuit to the lock magnet. The lock 16 on the magnet armature is bevelled so as to engage one of the notches 51 in the tappet 5, if this tappet is drawn forward before resetting the lever to normal. The contact 44 is closed by the depression of the pin 46 by the tappet 9, when this is lowered by the replacement of the catch bolt when the lever is normal: in the safety position, the notch 50 registers with the pin 46. In the mechanical lock shown in Fig. 2, the weighted pawl 52, which engages the teeth 59 on the tappet 5, is normally held clear by the pawl 57, but is released by the engagement of the pin 49 with the end 55 of the pawl 57. When the lever and catch bolt are reset to normal position at danger, the pawl 52 is reset by the tappet 9 depressing the pin 46.
