Abstract: 399,521. Changing-signs. MITCHELL, C., 27, Balmoral Road, Blackpool. March 29, 1932, No. 35613/31. [Class 3 (i).] Optical-projection apparatus comprises in combination a kaleidoscope, a source of light, a projection lens or lens system, means for continuously rotating the kaleidoscope whereby the continuously changing' designs produced therein by multiple reflection may be projected upon a ground glass or similar screen, a transparent screen adapted to carry advertising or like matter between the ground glass screen and the kaleidoscope, and means for traversing the transparent screen past the ground glass screen, the arrangement being such that the matter carried upon the transparent screen is superimposed upon the projected designs. As shown in Fig. 1, a casing 1 is provided with a ground glass screen 2 and is divided into three parts by means of partitions 3, 4 and 4a. A kaleidoscope 5 is mounted on rollers 6 carried by spindles 7 journalled in plates 8, and carries a sprocket 10 driven by a chain 11 from a sprocket 12, which together with a sprocket 13 is fast on a shaft 14 driven by a motor 17. Between the screen 2 and the partition 3 are journalled four rollers 18 each having a driving sprocket 18<1>, a chain 19 passing over all the sprockets. One roller carries a bevel wheel 20 meshing with a bevel wheel 21 on a shaft 22 carrying a sprocket 23 connected with the sprocket 13 by a chain 24. A flexible transparent screen 25 carrying advertising or like matter runs over the rollers.

Abstract: 931,623. Multi-unit rotary piston mechanisms. CURTISS-WRIGHT CORPORATION. Oct. 19, 1960 [Nov. 17, 1959], No. 35838/60. Class 110 (2). In a multi-unit rotary piston mechanism comprising at least three units, each having internally meshing rotors of the type with n and n+1 lobes, a onepiece crank-shaft extends through all the units. As shown in Figs. 1 and 2, a rotary I.C. engine comprises four units 16, each comprising a housing having parallel spaced-apart end members 18, 20 and an interconnecting peripheral member 22 providing a chamber 24 having the profile of an epitrochoid having two circumferentially-spaced lobes 34. Within each chamber is housed a rotor 14 having three apices 36 fitted with sealing strips 60. The rotor is mounted on a cranked portion 26 of a one-piece crankshaft 12 and fitted with an internally toothed gear 30 meshing with a gear 32 formed integral with a bearing bush 46. To permit assembly of the units, the combined bush and gear 46, 22 is made in halves and bolted together by bolts 52 and the internal diameter a of each end member 18, 20 is slightly larger than the diameter b of each crank-shaft crank portion 26. To permit accurate machining of the crank portions without interference from the journal portions the radius b of the crank portion less the eccentricity e is slightly greater than the radius c/2 of the journal portion. An inlet duet 40a common to two adjacent units opens into intakes 40, one for each unit, through which air and fuel is admitted. The mixture is then compressed to form a combustion mixture, ignited by a spark-plug 43 and thence expands and exhausts through a port 42 on the planetary motion of the rotor. Bolts 56 secure the members of a unit together and bolts 58 adjacent units. Alternatively through bolts may be provided to secure all the units together in which case the bolts 58 are unnecessary. Specification 791,689 is referred to.

Abstract: 817,836. Grinding. NEWSOME, J. March 14, 1957 [Dec. 14, 1955], No. 35853/55. Class 60. [Also in Group XXIX] The stone-carrying head of a honing or grinding device is mounted for reciprocation in response to pressure pulsations applied to a crank-operated piston to liquid acting directly or indirectly on a member forming part of or connected to the said head. A honing head 10, carrying four abrasive stones 12, has projecting pins 32 slidably engaging holes in a support member 14, so that the head 10 can reciprocate axially relatively to the member 14 but is constrained to rotate therewith;; the support member 14 is connected to a rotating driving member 16 by means of two upstanding brackets 34, Fig. 3, connected to the forked end 36 of a rod 38 extending from the member 16 by a pin 40 extending through a block 42 supported by the fork 36. A piston 18 projecting from the rear end of the head 10 is axially slidable in a cylinder 20 in the support member 14; a compression spring 30 bears at one end on the plate 22 closing the cylinder 20 and bears at the other end on a nut 28 on a rod 24 projecting from the piston 18, so that the piston 18 is adjustably urged towards the plate 22. A passage 44 in the support member 14 communicates with the cylinder 20 and is connected by a flexible pipe 48 to a passage 52 in the driving member 16 which passage communicates with an annular groove 54 in a stationary member 56 surrounding a portion of the driving member 16. The groove 54 is connected by a flexible pipe 58 to a cylinder 66 Fig. 2, in which a piston 64 is reciprocated by an adjustable crank pin 70 driven through a step cone pulley 76. The stroke and frequency of the recipro cation are thus both adjustable. The system is filled by a manually operable pump 80 bleed valves being provided to enable air to be forced out of the system. The abrasive stones 12 are carried on radially movable supports 100 having projections 102 engaging cam members 104 on a spindle 106 axially movable in the honing head 10. A compression spring 112 is interposed between the front end of the head 10 and a flange 114 on the front end of the spindle 106 ; a piston 108 projecting from the rear end of the spindle 106 is axially slidable in a cylinder 110 in the piston 18 of the head 10. A passage 116 in the support member 14 communicates with the cylinder 110 and is connected to a pipe 120 to a passage 124 in the driving member 16 which passage communicates with an annular groove 126 in the member 56. The groove 126 is connected by a flexible pipe 130 to a two way valve 132 to which is connected a supply pipe 134 and a return pipe 136, both connected to a pump 138, a pressure regulating valve 140 being interposed in the supply pipe 134.

Class 82(1) [Also in GroupsXI, XII and XXII] In a vacuum induction casting installation wherein the melting crucible 3 possesses a casting channel 7 located therebeneath closable by means of a movable sealing plug and surrounded by a second induction coil 8, the said coil is used to start the casting and also to warm the casting jet during the casting and for the temporary constriction of the casting jet. Air locks 14, 15, 16 enable moulds to be changed, and the crucible to be recharged, without breaking the vacuum in the main chamber 1, 10. Pouring is commenced by melting the solidified plug in the casting channel 7 by the coil 8 which is maintained energized during pouring. When a mould 12 is almost filled, the current in the coil 8 is increased to an extent to cause the jet to be considerably constricted, after which the sealing plug 9, 9<SP>1</SP> is brought into position under the channel 7 and the coil 8 switched off, metal thereupon freezing in the channel. The process is repeated when an empty mould is situated under the channel.
