Abstract: 781,483. Cutting moulded concrete blocks. INTERNATIONAL YTONG-STABALITE CO., Ltd. Sept. 15, 1954, No. 26779/54. Class 87(2). A device for cutting light concrete and similar materials comprises a rotary cutter the cutting elements of which are formed of wire and prior to such cutter a scraper conveyer device cuts the concrete to leave a predetermined depth. As shown, a framework 10 supports threaded rods 12, 13 co-operating with nuts 23, 24 respectively. An electric motor 16 rotates the rods and produces vertical movement of the nuts which carry a framework 11 carrying a rotary cutter 25 and a scraper conveyer screw 31 both of which are rotated by a motor 35. The cutter 25 comprises a bar 26 supporting discs 37 carrying wires 39 which may be held elastically, e.g. by springs, at one end. Moulds are passed first under the scraper conveyer which removes some of the excess material but leaves a predetermined depth to be removed by the cutter the direction of rotation of which is such that the material removed is thrown towards the scraper conveyer. A blast of air may be blown on to the cut surface to remove any loose cuttings.

Abstract: 392,176. Automatic screw-machines &c. NEW BRITAIN-GRIDLEY MACHINE CO., 140, Chestnut Street, New Britain, Connecticut, U.S.A.-(Assignees of Gridley, G. O.; 22, West End Avenue, New Britain, Montgomery, D. H. ; 1, Hudson Street, Berlin, and Wheeler, E. H. ; 210, Farming- ton Avenue, Hartford, all in Connecticut, U.S.A.) Oct. 5, 1931, No. 26809/32. Convention date, July 16. Divided on 390,511. [Class 83 (iii).] A turning lathe, screw-machine, or like multiple spindle machine has a work holder and tool holder movable relatively to each other in a continuous cycle and a semi-automatic stop which may be set at any time during a particular cycle so that upon completion of the cycle the feed mechanism is automatically disengaged. Power is derived from an electric motor 5 connected by a chain 10 to a high-speed countershaft 6 and to a central shaft 8, a jockey pulley being provided at 12. The shaft 8 is connected through back gearing 16 to the shaft which drives the work spindles ; this shaft carries a worm 14 connected through worm wheel 19, change gears 21, 22, overrunning clutch 24 and sliding clutch 25 to a worm 23 driving the main cam shaft 27 at its low speed, the worm wheel 26 which transmits the drive is arranged to slip on excessive resistance being encountered. A high-speed drive for the cam shaft is derived from the shaft 6 which is connected to the worm shaft 23 by clutch 28, Fig. 3, bevel gearing 29 and spur gears 32. The clutch 24 overruns so that the high speed is effective when both high and low-speed clutches are engaged. The high. speed clutch 28 is normally automatically controlled while the low-speed clutch 25 is moved manually by a rod 33 operated through a handle 35, this rod crosses the shaft 36 for controlling the clutch 28 and the two are interconnected so that low-speed disengagement effects the high-speed disengagement ; a brake 43 is also actuated to stop the feed shafts when the lever 35 is operated to throw out the clutches. For manual rotation of the cam shaft a hand shaft 44 is shifted to the right, Fig. 5, to engage wheels 45, 31, interlocking means being provided to prevent hand and power means in operation at the same time. Means are provided to stop the feed automatically at the end of an indexing operation, to effect this an arm 48, Fig. 5, slidably keyed to the shaft 46 upon which the handle 35 is mounted, is shifted at any time during a cycle by a lever 49 into the path of a lever 50, cam-controlled from the shaft 27, and is thus operated to throw out the feed clutches. A stock stop is provided which is normally automatically actuated by an auxiliary cam shaft 75 but may be moved manually to an out-of-the-way position when the feed has been stopped to permit removal of short ends of stock.

Title: Improvements in and relating to the humidification of conditioning chambers and the like for bread and the like or dough
IPC: A21B1/08
Filed: 1945-10-15
Abstract: 602,402. Proving appliances. SEVILLE, J. R., and BAKER PERKINS, Ltd. Oct. 15, 1945, No. 26901. [Class 28(i)] [Also in Groups XII and XXXV] A humidistatically controlled conditioning chamber 1 for bread &c. is humidified by the admission of steam in a series of puffs during a correction period when the humidity drops below a predetermined value. The steam is admitted through a pipe 5 under the control of an automatic valve 9 which may be magnetically operated and controlled by a time switch 20 and humidistat, 11, 12. The time switch, Fig. 2, comprises a rotary cam 13 driven by a motor and having a depression 14 for actuating an arm 15 to open or close contacts 16, 18 in series with a contact 17 controlled by humidistat 12. On the starting up or first stop, humidistat 11 actuates valve 9 over a contact 19 to supply steam continuously until a predetermined humidity somewhat below that required is reached. During the second stage or correction period, contact 19 is opened by humidistat 11 and valve 9 is actuated intermittently over contacts 16, 17, 18 to supply steam in puffs. When the required humidity is attained, contact 17 opens and valve 9 is closed continuously. For a fall in humidity the reverse obtains. A retaining cam may be provided for actuating a switch in the motor circuit to cut off the latter when the contact 17 is opened, said motor switch being in parallel with contact 17 and being closed thereby to start the motor. Alternatively a single humidistat 12 may be provided controlling the valve 9 to give puffs of steam only. The steam may be admitted into a separate chamber in which the air is conditioned and then conveyed to the conditioning chamber through pipes by fans.

Abstract: 645,791. Variable-speed chain gearing. MARKLEW, F. J. W. Oct. 18, 1948, Nos. 26977/48 and 5808/49. [Class 80(ii)] In a derailleur type variable speed chain gearing for cycles an auxiliary free-wheel sprocket wheel 13 is axially slidable by back - pedalling to position the driving chain 14 to engage either of two rear wheel sprockets 1, 2 on resumption of forwardpedalling. The sprocket freewheel boss 21 is mounted on a transverse hollow shaft 12 the axial movement of which is controlled by a movable cylindrical cam 15 secured thereto by a bayonet connection 19, 20, a fixed cylindrical cam 6 secured by projections and notches 8, 9 to a barrel 5 mounted on a bracket 3 depending from the cycle rear axle, and a compression spring 28 acting between a barrel closing end cap 30 and a flange 29 of a rod 22 which by a thrust bearing 23 loads the cam surfaces into engagement. Back-pedalling causes the sprocket wheel 13 to rotate the shaft 12 which is thereupon moved axially by cam surfaces 10, 17 to align the sprocket wheel 13 with the opposite rear wheel sprocket. Further back-pedalling returns the members to their original positions. The spring 28 also has a torsional force to load a chain tensioning jockey wheel or pulley 26 supported in ball bearings 27 by a flexible arm 24 secured to the rod 22. Modifications to the cams provide for three speed ratios, processional or otherwise, and for four speed ratios. The two speed arrangement may operate in conjunction with three rear wheel sprockets by axially adjusting the barrel 5 in its holder 4 to cause selection of the middle and either of the two centre sprockets. The spring 28 may operate only as a compression spring and an external spring is used to load the jockey pulley. The arm 24 may be shaped to form a chain guard.

In the Figure, 1 represents a length of metal strip, the part to the right of the Figure being shown with the majority of the projecting tabs 9 removed. There is also shown a length of strip cut-off from the continuous length 1 and in this strip the tags 10 are bent downwardly so that they will pass through appropriate apertures in the insulating panel 3. The panel 3 comprises a plurality of holes arranged in a co-ordinate array though not all possible locations in the co-ordinate array need be provided with holes. The strips are preferably, though not necessarily secured to the panel 3 by bending over the tabs on the undersurface of the panel. Components such as resistors, capacitors and interconnecting wires are arranged on the under-surface of the panel 3 in a direction transverse to the strips, their leads being passed through holes not occupied by the tabs and then bent over the strips to make contact therewith as appropriate. The leads are then secured to the strips by dipsoldering. The Specification also describes, Fig. 5 (not shown), a device for cutting-off unwanted tabs from the strip 1. The device may be programmed so that the strip can be fed to it continuously and the cutting operation performed automatically. A modified form of apparatus, Fig. 4 (not shown), is associated with a further device to which the strip is fed after the undesired tabs have been removed, this device automatically bending the tabs over as shown at 10. From here the strip, and such appropriate lengths may be fed to a further apparatus which positions them according to a programme in the correct position on the panel 3. Provision may also be made for inserting the components automatically in the circuit and then automatically dip-soldering them to the strips. In a modified form of circuit construction the tabs all extend from side of each strip and are not bent over so that in the completed circuit the strips are arranged with their planes perpendicular to the panel 3.

Class 139 [Also in Groups XIX and XXXVIII] In an indicator adapted to display any one of ten symbols carried by three coaxially mounted units which rotate together but are relatively movable axially, one symbol is normally displayed and any. one of the other nine symbols is displayed by selective energization of one or a combination of two out of four actuators. Nine of the symbols are complete in themselves, the' tenth being formed by overlapping two of the symbols. As shown, the indicator comprises three units 1, 2, 3, which rotate with the shaft 4, the units 1, 3 also being axially slidable on the shaft. Normally the symbol 0 on one face of unit 2 is displayed through an aperture 14. Energization of a magnet 5 rocks the shaft clockwise through 90 degrees, Fig. 3, through a link 9 to display "1." Similarly, energization of a magnet 8 rocks the shaft 90 degrees anticlockwise through a link 10 to display "4." Energization of a magnet 6 singly, lowers the upper unit 1 through a link 11 to dsplay "9," but if magnet 5 or 8 is also energized at the same time to rock the shaft the symbols "2," "3," respectively, are displayed. A magnet 7 when energized singly raises the unit 3 through a link 12 to display "6" the symbols "7," "5" being displayed respectively according to whether the magnet 5 or 8 is energized with magnet 7. To display "8," both magnets 6, 7 are energized. This brings the symbols 6, 9 on the lower and top units respectively into the display position, the symbol 9 overlapping the symbol 6 to produce the symbol " 8." The ten symbols are thus selected by energizing four magnets in combinations of 0. one or two at a time. Means (not shown), are provided to lock the solenoids in operated or in normal position and a spring 13 returns the shaft to normal position.
