Inventor: HARVEY GEORGE COLLINS
IPC: B63H3/04
Filed: 1952-10-07
Abstract: 733,232. Variable-pitch propellers. SLACK & PARR (MARINE), Ltd. Oct. 7, 1953 [Oct. 7, 1952], No. 25063/52. Class 114. Control gear for a variable-pitch marine propeller comprises a thrust bearing 23 at the front end of a reduction gear housing 11 and mounted on a control member 14 coaxial with the propeller shaft 10, and a pivoted link 37 connected to the bearing and to a screw and nut or other mechanism for effecting movement of a free end 40 of the link 37 to move the control member 14 axially and so vary the pitch of the propeller. A rotatable sprocket wheel 48 attached to a projecting end 46 of the screw 43 of the screw and nut mechanism rotates the screw to traverse the nut 42 which is connected by an arm to the free end of the link 37. The link has pivot pins 38 intermediate its length, secured to the thrust bearing housing 31. As shown, two parallel links 37 are used, one at each side of the screw and the thrust bearing, the links being pivoted to arms 35 pivoted on a pin 32 extending across an extension 17 of the housing 11; the screw 43 is parallel to the control member 14. The thrust block housing 31 slides on guide rods 51 which pass through apertures in lugs on the end-plate of the housing. Oil may be supplied to the propeller through a pipe 54 and a bore in the control member 14.

Title: Improvements in or relating to electro-magnetic variable-speed drives
IPC: H02P7/06
Filed: 1955-09-02
Abstract: 796,998. Electromagnetic couplings. SCHMID, W. K. Sept. 2, 1955, No. 25314/55. Addition to 748,255. Class 35. An electromagnetic coupling has a driven outer member 1, and an inner armature member 6, the coupling being controlled by periodically interrupting the current exciting the poles 4 of the outer member, or the current passing through the armature winding. The duration of the current pulses is adjusted by moving the brush 18 along the surface of a taper-contact drum 12. As shown, the exciting poles and the armature are connected in series, but they may, be in parallel. For greater sensitivity of control, the pole windings may be fed from an exciter which is fed with current impulses from a battery connected in series with the impulse transmitter. If desired, the intermediate exciter may be disconnected at high rates of slip. For greater sensitivity two exciters may be used in tandem. It is described how the principle may be applied to a lathe or vehicle drive. The armature may be commutated or polyphase, and the coupling gap may contain magnetic liquid.

Title: Improvements in or relating to methods of improving the properties of incombustibility of acoustic material
IPC: B05D1/02
Filed: 1948-09-29
Abstract: Porous acoustic material having a high coefficient of acoustic absorption and suitable for use in the form of self-contained objects is sprayed with an incombustible sticky substance from a distance such that a porous layer consisting of virtually separated particles of the incombustible substance is obtained on the surface of the material.  By materials having a high coefficient of acoustic absorption is meant materials having far frequencies exceeding 600 c/s. a coefficient of absorption of at least 70 per cent.  The incombustible substance may be a colloidal solution, e.g. water-glass in water in the ratio of 1 : 2 to 1 : 4.  Several sprayings may be carried out provided each layer is completely dry before being sprayed on.  Granular incoherent material may be sprinkled on to the sticky substance to form a non-continuous layer, the superfluous material removed and further sprayed with the sticky substance to form a discontinuous layer.  This granular material may consist of incombustible particles, e.g. shavings and chips of incombustible synthetic resin, glass splinters or sand or it may be sawdust, wood fibres, wood chips and cork powder.  The spraying liquid may be mixed with colouring matter, e.g. zinc white.

Title: Counting device for apparatus delivering liquids
IPC: B67D7/14
Filed: 1951-11-06
Abstract: 711,980. Counting-apparatus. WYDLER, H., SIEBENMANN, K., and HERZIG, H. Nov. 6, 1951 [Nov. 9, 1950], No. 25987/51. Class 106 (1) Liquid dispensing apparatus provided with a series of volume registers or counters 6, any one of which can be clutched to the drive by actuation of a corresponding lock 16, is characterized in that a cam on each lock barrel co-operates both with a respective clutch control member and with slides of a crowding lock preventing actuation of more than one lock barrel. The cam is shown as a semi-cylindrical extension 17 of the lock barrel which, when turned clockwise, Fig. 1, releases a clutch control arm 8 to the action of a clutch-engaging spring 41. There are two rows of counters 6 adapted to be driven through pinions 9 from two interconnected parallel shafts 10 driven from a main shaft 14. The crowding lock comprises, for each row of counters, a row of abutting bars 18 formed with a part circular recess 20, Fig. 5, at one end, and with rectangular recesses 21, above the level of the recess 20, at both ends. When a lock barrel is turned, its cam 17 immediately enters the recess 20, so blocking leftward movement of all bars 18 to the right, and then, during its second quarter turn, thrusts all the remaining bars to the left. The two rows of bars are interconnected by a cam-ended bar 22 engaging pins 24 on the end bars 19, so that the other row of bars is also blocked against movement. In this way, simultaneous rotation of two lock barrels beyond the quarter turn and effective to engage their clutches is prevented. Pins 29 projecting from the rear of the cams 17 engage angle slots 28 in a pair of return slides 27 disposed behind the two rows of locking bars 18, 19. These slides 27 are interconnected by levers 36 on a vertical shaft 34 and are displaced to the left when a lock barrel 16 is turned. Pins 30 on the slides 27 engage the end bars 19, and so return the two rows of locking bars when they are restored with the operated lock barrel. A block 31 on the lower slide 27 normally prevents inward movement of a control plunger 39 of the dispensing apparatus. Displacement of the slide, consequent upon operation of a lock barrel to engage a counter, moves the block 31 clear of the plunger 39, so permitting liquid to be delivered, the plunger being operated against a spring 40 by a pin 38 on the lever 36.
