Abstract: 499,223. Screw propellers; toothed gearing. VEREINIGTE DEUTSCHE METALLWERKE AKT.-GES. July 30, 1937, No. 21116. Convention date, Aug. 12, 1936. [Class 114] [Also in Group XXIV] In gear for varying the pitch of screw propeller blades of the kind comprising double return epicyclic gear each double planet wheel is formed as one wheel with wide continuous teeth, while one or both of the central wheels engaging therewith is or are provided with corrected teeth, i.e. although having the same diameter they have a different number of teeth. A pinion 1<1> forms the final drive through bevelled wheels with the propeller blades, whilst another similar pinion 1<1> is secured upon the propeller shaft. Between these two is a double train of epicyclics carried by two cages of which one is fixed and the other is adjustable. The planet pinions 2<1> are broad and mesh with the pinion 1<1> and an intermediate pinion 4<1>. Although the pinions 1<1> and 4 are of the same diameter, they have a slightly different number of teeth whereby an overall large gear reduction is obtained.

Title: Improvements in flashing-light direction signalling arrangements for vehicles
IPC: B60Q1/34
Filed: 1953-07-30
Abstract: 725,087. Thermal switches. VERNHES, J. M. July 30, 1953, No. 21203/53. Class 38 (5). [Also in Group XXXVIII] A flashing switch for a motor vehicle signalling device consists of two bimetallic strips and an electromagnetic holding arrangement. The two strips 1, 2, are arranged parallel to each other and have adjacent ends fixed at 3 and 4. When heated they tend to move towards each other as shown by the arrows, F, F<SP>1</SP>. When the circuit is first completed current flows over line 8 through contacts 7 and 6 along strip 2 and through electromagnet winding 12 to outlet terminal 10. As strip 2 is constructed at least partly of magnetic material it is attracted by the electromagnet and contacts 6 and 7 are held together until the heating effect of the current passing through the strip 2 creates a force (F') in excess of the magnetic attraction whereupon the strip moves upwards with a snap action and contacts 6 and 7 separate. A high resistance heating coil wound round strip 1 is connected in shunt between 8 and 10 and when contacts 6 and 7 part serves to heat strip 1 as strip 2 cools. Consequently after a short interval strip 1 presses strip 2 down again so that contacts 6 and 7 remake.

When using the plant, container 1 is filled with coffee, cocks A 20  and B 20  are turned so that filling funnel T 20  is connected to container 1 and cock A 1  is adjusted so that filling funnel T 1  communicates with container 1 which can thus be filled with water by pouring it into funnel T 20 . Cocks A 1  and B 20  are closed and the container are left to stand for at least twelve hours. Then container 2 is filled with coffee, cocks A 1  and B 1  are turned so that containers 1 and 2 are in communication and cock B 20  is adjusted so that water can again be supplied to container 1 through funnel T 20 . The liquid already in container 1 is forced into container 2. After another twelve hours, container 3 is filled with coffee and water is again supplied through funnel T 20  and the containers are filled successively at twelve hourly intervals. When container 19 has been filled with coffee and left for at least twelve hours, withdrawal of the first concentrated extract begins and cock B 18  is adjusted so that container 19 becomes connected to withdrawal conduit E 19  after which cockc A 18 , B 18  are again adjusted to connect containers 18, 19. Meanwhile, container 20 is filled with fresh coffee after which the liquid is drawn off from container 1 and liquid is supplied to container 2 so that the liquid is displaced through all the containers to fill up container 1. Container 1 is then emptied of the used coffee grounds and refilled. Examples are given which include the dimensions of the containers.

Title: Improvements in or relating to electric switches
IPC: H01H25/06
Filed: 1960-06-17
Abstract: 959,773. Secret contact-combination switches. M. RORKE. June 17, 1960, No. 21424/60. Heading H2B. A selector switch particularly for the ignition circuit of vehicles is operated by a rod which is first rotated to select a required pair from spring contacts 60 arranged in a circle around the central contact pair 59, and then moved axially to operate the selected contacts. Certain circumferential contact pairs 60 are connected in series with the ignition circuit and in order to complete this circuit, a knob 48 and spindle 47 are rotated in a counterclockwise direction. Slidably keyed on the spindle 47 is a sleeve 30 which rotates with it and in turn, by a pin-andslot connection, turns a tube 17 on the outside of which is a helical thread. Engaged in the thread is the end of a grub-screw 19 connecting together a collar 19 and a sleeve 16. Since the bearing 15 and hence the collar 16 cannot move downwards, the counterclockwise rotation of the helix carries the grub-screw 20 with it past the curved end of a detent 56 which by rising slightly allows the screw 20 free passage. The spindle 47 thus rotates freely and carries with it at its lower end a setting-arm 52. When this arm is in a selected position, indicated by a dial 42 carried by the sleeve 30, the spindle 47 is depressed against its spring 51 and the setting arm 52 descends through a selected radial slot in a block 7 and depresses a corresponding plunger 10 by means of a projection 11. The selected plunger 10 thus bridges its associated contacts 60 by means of a metallic bridging-piece 13. By withdrawing the spindle 47 and rotating it to the other selected switch positions and there depressing it, the required contacts are bridged and the ignition circuit completed. In order to prevent unauthorized use, the vehicle horn may be connected in series with the central contacts 59 and with a particular pair of circumferential contacts 60, whose plunger 10 is arranged so that the contacts are normally bridged but opened when the spindle 47 is depressed. Thus, unless this particular switch position is first selected and the spindle 47 depressed to break the horn circuit, any depression of the spindle 47 and its contact ring 54 will sound the horn. In order to break the ignition circuit, the knob 48 and spindle 47 are rotated in a clockwise direction until the screw 20 strikes the straight edge of the detent 56, when the helix 17 lifts the screw 20 and with it the sleeve 16, which by means of its flange lifts the bearing plate 14. This in turn lifts the contact plungers 10 and counterclockwise rotation of the spindle 47 will cause screw 20 to contact detent 57 and then lower the plate 14 again to its normal position.

An endless passenger transport system for connecting a series of stations in both directions comprises either a pair of endless tracks 12 each for travel in one direction only and each passing through all the stations, or a single track having two parallel closely spaced runs which pass through all the stations, there being suspended from the track individual transport units, Fig. 8, driven by track mounted motors 60 which engage flanges 65 of the units, said units being driven at a slow speed through the stations in contacting relationship and at a high speed between stations where they travel in open formation. The units each consist of a floor 6, roof 7, transverse walls 10, a fixed longitudinal wall 8 and an openable longitudinal wall 9. The wall 9 is formed of portions 9a, 9b pivotable at 14a, 14b to outward horizontal positions. Also portions 18 of walls 10 are pivotable at 19 to position 18a providing communication between the units at a station. The wall 9, and wall portions 18 are opened at the station by means of guide rollers 36, 40 and 47 attached thereto being engaged in slots 37, 41 and 48 which are contoured to move the rollers to the dotted positions causing the walls to open. Oppositely contoured slots at the exit from a station cause the walls to close. A latch mechanism 50 is released by a rod 53 engaging a cam on entering a station. The electric motors 60 are spaced along the track between stations and have a drive roller 61 engageable with flange 65 and a rotatably mounted stator supporting an idler roller 63, whereby the gripping force exerted on the flange is proportional to the driving torque applied by roller 61. At a station there is provided alighting and boarding cranked handrails 20, 21, those portions of which are parallel to the track passing through the wall openings provided by wall portions 18. The lower portions of walls 9 are horizontally ribbed and pass under a similarly ribbed platform extension 22.
