Title: Improvements in axial flow fans
Inventor: HAWES STANLEY PETER
IPC: F04D29/54
Filed: 1955-01-24
Abstract: 792,369. Axial-flow fans. AIRSCREW CO. & JICWOOD, Ltd. Jan. 24, 1956 [Jan. 24, 1955], No. 2037/55. Class 110 (1). In an axial-flow fan of the kind in which the impeller blades operate within a cylindrical casing from which extends an air duct, the impeller projects an air stream having an outward component of velocity, and vaned guiding means in the path downstream of the air stream gradually change the direction of the air stream so that it obtains an inward component of velocity within the air duct. The fan impeller c is followed by guide vanes f extending from a cylindrical duct h to a generally conical fairing e. The vanes f are curved and are inclined in the direction of rotation from their outer to their inner ends. The upstream edges k of the vanes fare nearly vertical and the downstream edges i meet the fairing e at an acute angle. The fairing e is of smaller diameter than the impeller hub, to permit the inward component of velocity to be obtained within the duct h; it may be replaced by a cylindrical tube substantially smaller in diameter than the impeller hub. The guide vanes may be embodied in a unit disposed downstream of a separate conventional fan. The guide vanes and the fairing may rotate.

Title: Improvements in or relating to methods and means for folding dough pieces
Inventor: PALMER AUSTIN RICHARD
IPC: A21C9/08
Filed: 1956-01-27
Abstract: 835,240. Dough-working machines. BAKER PERKINS Ltd. Jan. 28, 1957 [Jan. 27, 1956], No. 2760/56. Class 87(2). Elongated pieces of dough are folded for accommodation in bread tins by moving them sideways and at the same time folding over portions of their lengths. The machine, Fig. 1, is driven from a motor 41 by a chain 40 which rotates a driving roll 43 of a conveyer 10, a sprocket 44 on a shaft 52, a sprocket 45 from which a driving roll 24 of an. apron 23 is driven, and a sprocket 42 from which, through a chain drive and bevel gearing, bands 31 are driven. Thus all the parts of the machine move in synchronism. A chain 53 from the shaft 52 also rotates a disc 19 carrying a pin 20 which oscillates a lever 17 and thereby causes a flap 12 to open and close, in synchronism, a trough 9. When the trough is open a dough piece 1, already partially divided as shown, is fed through it on to the conveyer 10 which carries it between converging fences 21, preferably faced with polytetrafluorethylene, and beneath the apron 23, the fences and the apron forming a first zone in which both ends 5, 8 of the dough piece are bent backwards. The dough piece then reaches a second zone where its centre 3 is retarded by a drag post 27 which is carried at a suitable speed on a chain 28 driven by a sprocket 29 on the shaft 52, moving bands 37 at the same time holding it down. The driving roll 39 of the bands 37 is driven through a chain 50 from the shaft of the other sprocket of the chain 28. The dough piece, now folded in the the form of a W, is squashed together in a third zone by the bands 37 and the side bands 31, which are guided by backing plates 35, and then rolls off the end of the conveyer 10 into a bread tin. A rectifying device, Fig. 4, to cause a dough piece to lie squarely on the conveyer 10, may be linked with the flap 12 of the trough so that when the flap is lowered to release the dough piece a rectifying flap 63 is swung momentarily into its path to align it. In a modification, Fig. 6, the dough piece is folded in the form of an N by drawing it, in the first zone, between fast and slow bands 107, 108 and then, in the second zone, between conversely arranged slow and fast bands 109, 110, after which. it may be transferred to the bread pan or further compressed between bands 31. A deflector bar may be adjustably mounted to prevent the pieces from turning over as they roll off the end of the conveyer. Specification 794,187 is referred to.

Title: Photographic cameras having built-in exposure meters
Inventor: WIESSNER MANFRED
IPC: G03B7/06
Filed: 1961-01-24
Abstract: 917,907. Photographic cameras with built-in exposure meters. KAMERAUND KINOWERKE DRESDEN VEB. Jan. 24, 1961, No. 2765/61. Class 98 (1). In a photographic camera with a detachable rear wall and a built-in exposure meter which is coupled with setting members for exposure factors including film sensitivity, on the setting member for the film sensitivity there are secured one end of a return spring and a catch disc held by a catch spring, and control means is provided operable by the detachable rear wall to maintain the catch spring in engagement with the catch disc when the rear wall is in position on the camera and for moving the catch spring out of engagement with the catch disc when the rear wall is removed to allow the return-spring to return the setting member for the film sensitivity to a predetermined position where the exposure meter is inoperable or indicates non-setting of the film sensitivity, the exposure meter being rendered operable or indicating setting of the film sensitivity on further setting of the film sensitivity setting member after the rear wall has been replaced. As shown, the position of a follow-up member 6 for a photoelectric exposure meter pointer 36 is controlled by a lever 5 pivoted on a T-shaped slide 7, the position of which is determined by a cam 8 fixed to the shaft which carries the film sensitivity setting member 33. In use the diaphragm is adjusted by means of an arm 35 and through a cam surface 27 on the diaphragm operating arm moves endwise a shaft 1 carrying a pinion 26 engaging a shutter speed setting member 3. The shaft 1 is threaded at 2 to engage a nut 4 constrained by a fixed pin 25 to move axially. Thus both diaphragm and shutter speed adjustments through the positioning of the nut 4 engaged by lever 5 alter the position of the followup pointer 6. On removing the camera back 13 a pivoted lever 14 is pressed outwardly by a spring 15 and frees a catch disc 9 on the film sensitivity setting shaft from a catch spring 10, and a return-spring 11 secured between the cam 8 and the camera housing 23 rotates the cam until the cam nose 8a is arrested by a fixed pin 12 and the tail of the T-shaped slide 7 rests in the cam recess 8b, so that the lever 5 allows the spring 31 to move the follow-up pointer out of the exposure meter window 34. On reclosing the camera, e.g. after changing the film, the cam 8 remains in the position to which it moved on removing the camera rear wall, and before the exposure meter can be used as a follow-up control for diaphragm and shutter speed setting the film speed must be set by rotating the member 33 to tension the spring 11 and by means of the cam 8 to return the slide 7 to the operative position shown. In a modification (Fig. 4, not shown), the lever removing the catch spring 10 from the catch disc 9 is moved outwardly against the action of a spring by a pin on the camera back engaging a spring-mounted latching slide on the lever.
