Abstract: 1,115,318. Electrophonic musical instruments. D. H. BALDWIN CO. 4 April, 1966, No. 14829/66. Heading G5J. [Also in Division H1] A photo-electric musical instrument (e.g. an organ) comprises a rotating pitch disc 8 and a fixed voice disc 9 which forms one wall of a sealed chamber 35 containing several arrays of photo-electric elements 26. As described, desiccant 32 ensures that the chamber 35 (sealed by rings 23, 25) is maintained free from moisture, thus eliminating the need for encapsulated photo-cells. Arrays of open photo-cells each of which can be individually selected by co-ordinate techniques under control of keys and stops (Fig. 2, not shown) are provided thus eliminating the use of shutters. The pitch disc 8 is biased by a spring 20 into engagement with a drive 17. A magnet may be lowered to cooperate magnetically with teeth on an armature 38 to vary the rotational speed of the disc at a sub-audio rate to effect pitch vibrato. In order to reduce thump due to transients when additional voices are introduced, a balanced amplifier and centre-tapped transformer are employed and each stop operates ganged contacts or a potentiometer contact to gradually connect in the additional photo-cell array. Several voicing bands relatively displaced in phase are provided on the voicing disc for each pitch band on the pitch disc to give the effect of ensemble.

Title: Improvements in or relating to manipulating devices
Inventor: BRITT JACK
IPC: B25J9/06
Filed: 1955-05-26
Abstract: 797,882. Linkwork. ROLLS-ROYCE, Ltd. July 5, 1956 [May 26, 1955], No. 15294/55. Class 80 (3). A manipulating device for handling articles by remote control, particularly articles in a space containing a substance, such as liquid sodium, at high temperature, comprises a normally flexible girder 11, formed of a pair of spaced flexible strips 14, 15 and series of interconnecting links 20, 22, 23, passing through a rigid rectangular guide casing 10 having vertical and horizontal straight portions 10a, 10b and on connecting curved portion 10c. Pairs of the links 20 are pivoted to lugs 16 spaced along the strip 14 and each link is pivotally connected to the link of the adjacent pair. The links 22, 23 are coupled together and bridge the connecting points between the links 20 of adjacent pairs to allow opening and closing movements of the links 20 as they pass around the guide casing 10. The trip 15 carries a series of abutment blocks 27 which have shaped faces adapted to engage between an abutment face 26 on one link 22 and shoulders on the end of the adjacent link to lock the links rigid when they are in and beyond the horizontal straight portion 10b of the guide casing. In the curved part of the guide casing which is made of greater depth the flexible strip 15 with the blocks 27 moves away from the strip 14 so that the locking between the links is released to allow flexing of the girder 11 around the curved casing. In the vertical straight portion 10a of the casing the block 27 assumes a position clear of the locking faces of the links 22. Thus the flexible girder can be passed freely through the guide casing 10 by any suitable actuating means to project out rigidly from the horizontal portion 10b a desired extent. A bracket 19 is connected across the strip 14, 15 at their extremity to support an article gripping device 12 such as described in Specification 797,881, [Group XXX], and a flexible shroud 13 encloses the whole girder and guide casing structure. The casing 10 is supported so that it can be moved vertically and rotated about the axis of the vertical portion so that the gripping device 12 can be moved as desired.

Title: Improved method and device for peeling veneer
IPC: B27C7/04
Filed: 1947-06-10
Abstract: 627,450. Veneer cutting lathes; drivers. ABBEY, A. (Aktiebolaget Siefvert & Fornander). June 10, 1947, No. 15306. [Class 83 (iii)] In a process and lathe for peeling veneer, two driving claws 3, 5 of different radial extensions are used to engage the driven end of the log, the one of greater radial extension, 5, being withdrawn to an idle position during the peeling operation before the peeling knife 21 reaches that circumference to which the said claw extends, the peeling operation then continuing to a smaller radius than that of the claw 5. In the arrangement shown, 3 is the fixed claw, the auxiliary claw 5 being rigidly mounted and axially but not rotatably displaceable along guides 6 with respect to the driving spindle 1. As the peeling knife 21 approaches the limits of the claw 5, at a pre-determined position, the step 24 on the slide 23 actuates the pin 20, lever 19, rack 18 and gear rim 16 to rotate the sleeve 14. This sleeve has no axial motion in the housing 2 and is provided with a helical slot 13 through which project two diametricallyopposed pins 12 of the driving-ring 10. The ring 10 also has an inward flange 11 engaging a groove 9 in the bush 7, which bush, together with the driving claws 5 are prevented from rotating with respect to the spindle 1 by means of a ring 8 fixed to the spindle between the claws and the bush. Thus actuation of the gear rim 16 rotates the sleeve 14 which in turn causes the pins 12 to move along the slots 15 in the housing 2 and thus move the ring 10, bush 7 and claw 5 all axially of the driving spindle and away from the log. Alternatively the slide 23 may have a stop-member actuating the rack 18 in one direction only to withdraw the claw 5-the reverse movement of the sleeve 14 being performed by suitable hand actuating means. Further, the motion of the claw 5 towards and away from the log may be produced by connecting the claw to a nut co-operating with a rotatable but not displaceable screw. When the distance between the fixed claw 3 and the spindle head is sufficiently great, a wholly or semi-automatic or a wholly hand operated device for displacing the auxiliary claw 5 may be mounted on the outside of the spindle head.

Title: Improvements in and relating to lifting rotors for aircraft
IPC: B64C1/00
Filed: 1950-06-20
Abstract: 674,489. Helicopters. HOHENEMSER, K. H. June 20, 1950 [July 18, 1949], No. 15424/50. Class 4. An aircraft lifting rotor comprises a centre portion rotatably connected to the aircraft, a plurality of blades connected to the centre portion in such a manner as to allow the blades to flap cyclically only about predetermined cyclic flapping axes, and to allow the blades to flap collectively only about predetermined collective flapping axes, the cyclic and collective flapping axes being, so located that a certain change in cyclic flapping angle produces a change in blade pitch angle different from the change in blade pitch angle produced by an equal change in collective flapping angle; and is characterised in that the collective flapping axes are so located that an increase in collective flapping angle produces a decrease in blade pitch angle which is appreciably larger than the increase of the collective flapping angle and that the cyclic flapping axes are so located that a change in cyclic flapping angle produces a change in blade pitch angle which is appreciably smaller than the change of cyclic flapping angle. In one constructional embodiment of the invention illustrated in Fig. 6, a hub 25 is universally mounted on a rotor shaft 1 and has three arms 26 to which are pivoted, about axes 23, links 12. Blades 7 are rotatably mounted, about longitudinai axes 14, on the links 12 and carry control horns 17 which are attached at 18 to conventional pitch control mechanism. When the blades flap collectively the member 25 and links 12 will rock as one about the centre 27 of the hub whilst cyclic flapping will take place about the axes 23, the hub remaining stationary relative to the shaft 1. This arrangement provides a virtual cyclic flapping axis 28 and a virtual collective flapping axis 30 passing through the point 18 and the centres 27, 29 of the hinges of the hub 25 and link 12 respectively. The virtual " Delta-three " angles for cyclic and collective flapping are denoted # 3 CYC and # 3 COL respectively. The relationship between the change in cyclic flapping angle ## CYC  and the corresponding change in blade pitch angle ## CYC  is given by:- and the relationship between the increase in collective flapping angle ## COL  and the corresponding decrease in blade pitch angle ## COL  is given by:- The invention is thus fulfilled if # 3CYC  is less than 45 degrees and if # 3COL  is greater than 45 degrees. Other embodiments of the invention are illustrated in Figs. 7-11 (not shown). The blades illustrated in Fig. 7 are provided with drag hinges and interconnected control horns.
