Abstract: 176,829. Haller, F. C. Oct. 12, 1920. Bakers' ovens.-A gas-fired baking-oven is charged and discharged at the same end, goods being carried circuitously in the oven by an endless conveyer. The conveyer comprises two endless chains 10 carrying pivotally-suspended trays 16 and driven over sprocket-wheels 11, 11<1>, sheaves 12<1>, and sprocket-wheels 12 by a motor 15 and gearing 15', or by a ratchet and pawl and hand-lever. The trays are loaded and enter the oven by the lower opening 20, pass up and down through the oven, and return by the horizontal path 9<b> to the discharge opening 21. The lower sheaves 12<1> are of smaller diameter than the upper series, and are arranged out of alignment with them, effecting a conservation of space. A baffle wall 23 at the lower opening encloses a cooler space for preliminary heating of the goods, and prevents escape of heat. The oven walls are described as formed of sheets of metal coated on either side with a heat-resisting and insulating composition reinforced by expanding metal, and the oven is heated by gas-burners 19.

Title: A method and apparatus for placing workpieces in a predetermined angular position in a machine tool
Inventor: WOOD FRANK
IPC: B23Q7/16
Filed: 1955-10-11
Abstract: 805,637. Machine-tool details. ARNFIELD, Ltd., J. & E. Jan. 11, 1957 [Oct. 11, 1955], No. 28994/55. Class 83 (3). Apparatus for placing workpieces 2 in a predetermined angular position in a machine-tool (not shown), e.g. a lathe, comprises means 3 for pushing the workpieces singly from a stack 1 to a transporter 4, means 20, Fig. 4, for rotating the work on the transporter to bring it to a predetermined angular position, and means 27, 28 for moving the transporter between the stack and the machine-tool to place the work in the machine-tool for a machining operation. The transporter has two pairs of work-gripping jaws 13 ... 16, Fig. 3, operated by screws 18, 19 of opposite hand rotated by a rack-and-pinion gearing 17 driven by fluid pressure. The jaws are mounted on sleeves 10, 11 rotatable between collars 12 on tubes 5, 6 which are separated by a washer 7 and adjustable radially of the piston rod 8 of a fluid-operated clamping device 9 for securing the tubes after adjustment. The transporter is mounted on a lever 27 carried by an arm 28 on a shaft 30 bearing in a carriage 31 movable along a guide 32 by a fluid-operated ram, Fig. 1. A fluid-operated rack 34, engaging a pinion on the shaft 30, rocks the arm 28, and a fluid-operated piston 29 controls pivotal movement of the lever 27. Operation. With the arm lowered, Fig. 1, the workpiece at the bottom of the stack is pushed axially into the transporter, on which it is rotated by the oppositely-reciprocating, spring- pressed plates 21, 22 of the device 20, until the plates engage driving flats 25, 26 on the work, thus bringing the work to the predetermined position, in which the jaws 13 ... 16 are closed by the gearing 17 and secured by the clamp 9. The transverse movement of the plates may stop their reciprocation. The arm is then pivoted towards the machine-tool and moved axially of the machine, by movement of the carriage 31, to clear the headstock. Opposite movement of the carriage follows to bring the work against the headstock centre, after which the tailstock centre is advanced to engage the other end of the work, which is then released by the transporter. Operation of the piston 29 and the rack 34 then withdraws the transporter. Means (not shown) associated with the arm 28 may prevent manual or automatic start of the machining operation until the work is correctly positioned. After machining, the work is removed by the transporter and preferably delivered to a station adjacent the magazine 1, where it can be ejected from the jaws by the operation of positioning the next workpiece in the jaws. The apparatus may be controlled by signals derived from a punched tape.

In one arrangement Fig. 1 one optical object is a material object 1 while the other is produced by a hologram 2. Both are illuminated by a laser 3 via a beam-splitter 6. The optical system 13 contains a convergent lens 13, two cylindrical lenses 15, 16 and a screen 12. In use, lenses 15, 16 are selected by trial and error from a set of varying powers until clear fringes appear on the screen 12. Alternatively, each lens 15, 16 may be replaced by a set of cylindrical lenses of the same fixed direction but of adjustable spacing to adjust the power of the set. In a modification of this arrangement Fig. 7, (not shown) lenses 15, 16 are replaced by a single cylindrical lens 38 which is mounted so as to be adjustably rotatable about the optical axis 11 as also shown in Fig. 8. Again, lens 38 may be selected from a set or be replaced by a set of parallel similar lenses. In another arrangement (Fig. 8) both optical objects are material objects 1, 820 illuminated by a laser 3. In setting up, objects 1, 820 are in identical states and orientations so that no fringes can be seen. The displacement to be observed is then applied to object 1 and lens 38 is adjusted until clear fringes are seen. Information is given on the interpretation of the observed fringe systems.
