Title: Improvements relating to the handling of biscuits
Inventor: WARD PETER
IPC: B23Q11/00
Filed: 1965-05-12
Abstract: 1,135,741. Endless conveyers. BAKER PERKINS Ltd. 9 May, 1966 [12 May, 1965], No. 20103/65. Heading B8A. When the feed of biscuits 2 by an endless conveyer belt 14 from a conveyer 1 to a conveyer 8 via a shoot 5, rises above a predetermined rate, the slope of the biscuits in the shoot 5 increases to trip an arm 41 of a switch 42. This brings about retraction of a tensioning crank 33 of the belt 14 causing the drive of the latter to cease until the biscuits in the shoot 5 slump down to a predetermined degree. In a modification (Fig. 4, not shown), the belt 14 is replaced by a belt (50) driven by an endless member (51). Closure of the switch 42 results in a gripper (55) holding the belt (50) from movement. The belt 14 comprises a series of laterally spaced tape-like belts each associated with a respective belt 2 and shoot 5.

Title: Foamed polymeric materials
Inventor: CHAPMAN JOHN FREDERICK
IPC: C08J9/14
Filed: 1964-05-14
Abstract: Foamed polymeric materials are prepared by polymerizing crude acrolein tetramer or methacrolein tetramer by contact with a polymerizing catalyst in the presence of a foaming agent, the crude tetramer having been pretreated by heating at 75 DEG  to 225 DEG  C. for a period not exceeding 12 hours.  By the terms crude acrolein and methacrolein tetramer are meant the crude cyclic tetramers prepared from the respective dimers by self-condensation in the presence of an aluminium alkoxide catalyst, i.e. acrolein tetramer is 3,4-dihydro-2H-pyran-2-methyl - (3,4 - dihydro - 2H - pyran - 2 - carboxylate). The pre-treatment may be carried out in an inert atmosphere, optionally with agitation.  The foaming agent is preferably a volatile halogenated hydrocarbon.  The prerferred catalysts are acidic ones, e.g. perchloric acid, aqueous fluoroboric acid and boron trifluoride etherate.  The preferred amount of catalyst is from 0.2 to 3.0% of the total weight of the foaming composition.  Advantageously, the composition contains a surfactant, e.g. a siloxane-oxyalkylene block copolymer.  A compound reactive with or copolymerizable with the acrolein or methacrolein tetramer may be incorporated, e.g. 2,2-bis-(p-hydroxyphenyl)-propane, an acetal made by reacting acrolein tetramer with a polyhydroxy or polycarboxy compound or the phthalate ester of 2-hydroxymethyl-3,4-dihydro -2H-pyran.

Abstract: 390,989. Gravity separation apparatus. MILLS & CO. (ENGINEERS), Ltd., J., Moss Iron Works, Heywood, Lancashire.- (Assignees of Pr³ss, M., 30, Moltkestrasse, Essen, Germany.) July 18, 1932, No. 20248. Convention date, July 18,1931. [Class 111.] A scraper for removing sludge from a settling- tank is carried by a floating carriage, which is moved backward and forward over the tank, and means are provided for automatically raising and lowering the scraper. As shown, a scraper shield 3, which is provided with an elastic blade 5 and rollers 4, is connected by arms 6 to rods 7. The rods 7 have rollers 8 at the lower end and are attached at the upper ends to a float 9. The float is drawn along the tank by chains 11 driven by a motor 10. During the forward motion the scraper pushes the sludge into a sump 12. As the float nears the forward end of the tank the movement of the chains 11 is automatically reversed and a lever 14, Fig. 3, on the float engages a cam on the wall of the tank and is turned so as to cause ropes or chains 13 attached to it to lift the scraper from the bottom of the tank. A catch holds the lever 14 in the turned position during the backward movement of the float and scraper. During the forward movement of the float an adjustable flexibly-supported plate 19 on the float pushes scum into an outlet trough 21. Plates 19 may be provided on either side of the float and a corresponding trough 21 at the back of the tank. In the case of long tanks several scrapers, which may be arranged to work in the same or opposite directions, may be connected to the same chains 11.

Title: Expansion joints and their manufacture
Inventor: FARRAR JOHN FREDERICK PALMER
IPC: F16L51/02
Filed: 1956-07-02
Abstract: 839,373. Expansion joints. FLEXONICS CORPORATION. July 2, 1956, No. 20449/56. Class 99(1). An expansion joint, Figs. 11 and 12, comprises an expander body 54 of a plurality of laminations and an adapter member 68 telescopically associated with the expander body having a wall thickness not substantially exceeding three times the composite wall thickness of the expander body the adapter member being welded to the expander body. In Fig. 13, the adapter member is indicated by 84. The weld may be a resistance weld formed by means of a pair of welding rollers. As shown split rings 76, 78 may be applied to the joint so as to ensure controlled flexing of-the expander body. These rings however may be omitted. The expander body is made up from tubes formed from sheet metal bent into tubular form and welded along a longitudinal joint. One such tube may be expanded by drawing an expanding member through it and then another tube which has not been expanded can be fitted within the expanded tube. The expanding member may then be drawn through the inner tube and another tube of the original size fitted. In this way a laminated wall of a desired number of laminations, within limits, may be fabricated. If a corrosive fluid is to be conducted the innermost wall may be of a metal resistant to the corrosive action of the fluid and the other laminations may be selected with a view toward radiation and conduction of heat.

Title: Improvements in and relating to vehicle brake testing apparatus
Inventor: WHALLEY FREDERICK
IPC: G01L5/28
Filed: 1958-06-26
Abstract: 876,265. Testing vehicle brakes. KISMET Ltd. Sept. 23, 1959 [June 26, 1958], No. 20496/58. Class 106 (2). Apparatus for testing the brakes of vehicles comprises transmitting means 18, 20 for applying rotary drive to the wheel of the vehicle and means (not shown) for indicating the force required to rotate the wheel against the action of the brake, the transmitting means being of varying mechanical advantage, so that the final indication given is a true indication of the force required to maintain rotation of the wheel. The wheel is supported on rollers connected by an endless chain (not shown) and mounted on shafts 7, 8, these shafts also supporting toothed wheels 9, 10. A third shaft 14 has rigidly attached to it a cam 16; and a cam 18 is free to rotate on the shaft 14. The cam 16 holds a pawl 17 in engagement with the toothed wheel 9, and a chain 20 is connected at one end to the cam 18, and at its other end to the toothed wheel 10. Pins 19 on the cam 16 slide in slots 19a machined in the cam 18. In use, when a wheel is resting on the rollers and the brake is applied, the shaft 14 is turned by means of a torque wrench. The pawl 17 is released by movement of the cam 16, thus freeing the rollers for rotation. Thereafter, the pins 19 engage the ends of the slots 19a and so drive the cam 18. Rotational movement is transmitted from the cam 18 through the chain 20 to the rollers. Initially, the chain acts on the lowest portion of the cam, as shown, and so the torque required to turn the rollers is less than would be required if the chain acted on the circular part of the cam 18. Thus an artificially low value is indicated by the torque wrench before movement of the wheel starts. Once the wheel is moving, the chain wraps around the circular part of the cam 18 and so a correct value of the force exerted by the brake is indicated on the wrench, which is graduated accordingly.

Title: Improvements in or relating to machines for agricultural, land-working, mining and other purposes
IPC: A01D17/14
Filed: 1946-07-10
Abstract: 614,144. Excavating earth. HAMLETT, H. W. July 10, 1946, No. 20583. [Class 68 (i)] [Also in Groups I and XXX] An excavating-machine comprises a tractor with one or more excavating tools in front which can be set at varying inclinations to the ground, each tool consisting of a tube having annular cutting means at its open lower end, and an internal worm conveyer, power drive motivating both tube and conveyer so that on forward motion of the machine a core of earth is cut which enters the tube and is conveyed therein by the worm conveyer. Fig. 1 shows such a machine adapted for harvesting root crops. The tractor 1 is fitted with a plurality of excavating tools, each of which comprises a cutter 2 with knives 8, a rotary perforated conveyer tube 3 and worm 4 which delivers the lifted crops through an opening 20 to a trough 5, wherein a pair of oppositely rotating worm conveyers 6 move the crops to each side of the machine from whence they are raised by elevators 7 to a delivery point. The tube 3 and worm 4 are driven in opposite directions by suitable gear-wheels 21, 22, 23 and 26, the worm-shaft 14 passing through a sleeve 15 on the end plate 12 of the conveyer. The working depth of the tools is adjustable by a front roller 45, the tools pivoting at the lower end of a bracket 17, the upper end of which has hydraulic means 54 connected to it at a point 52. A cleaning roller 80 is supported on a bar 41<SP>1</SP> to prevent earth clogging the tube. 3. The vertical movements of the roller 45 are transmitted to the hydraulic means by suitable connections. In a modification (Fig. 10, not shown), the pivot point of the bracket 17 is on a frame pivotally mounted on the tractor. Means are provided for raising the tools individually and collectively. Cultivating tools may be provided at the rear. Specification 610,571, [Group I], is referred to. The Provisional Specification also describes spring means in place of the hydraulic means, each means being so connected that on the mechanism meeting a large obstruction the engine will be disengaged. Power for the various parts may be provided from the tractor motor or a separate motor.

Title: Gear device for transmitting rotary motion
IPC: F16H29/06
Filed: 1932-07-21
Abstract: 394,148. Transmitting rotary motion; variable-speed gearing. BONNET, M., 8, Place Vintimille, Paris. July 21, 1932, No. 20596. Convention date, July 25, 1931. [Classes 80 (ii) and 80 (iii).] Rotary motion is transmitted with speed reduction between a rotary eccentric 3, Fig. 1, fast on a driving-shaft 1 and an aligned driven shaft 2 through pawls or struts 11, Fig. 2, which stub in succession against the inner surface of a drum 4 eccentric to a wheel 10 to which the pawls 11 are pivoted at 12. The drum 4 which is supported loosely upon the eccentric 3 is connected by links 5, Fig. 4, a frame 59, and links 6 to a fixed base so as to be incapable of rotation. The drum 4 therefore wabbles eccentrically round the wheel 10. The pawls 11 are spring-pulled so as to stub on the drum 4 in succession so that the wheel 10 is driven round and imparts a continuous drive to the shaft 2. Provision may be made for disconnecting the drive by allowing the frame 59 to rotate freely. A variable-speed form is shown in Figs. 5, 9, and 10. The hub 61 of a bicvcle wheel turns on a fixed axle 42 and is secured to a wheel 10 with pivots 12 for pawls 11 corresponding to similarly denoted parts in Fig. 1. The drum 4 is held against rotation about its own axis by a linkage inside it similar to that of Fig. 4 and anchored to a non-rotary frame 41 fast on the axle 42. The eccentric 3 on which the frame 4 is loosely carried is of variable throw. The load resistance thrusts the eccentric 3 to more concentric lower-speed positions and this thrust is balanced by the thrust of a control spring 55, so that the speed transmitted adjusts itself automatically to the load. The eccentric 3 is adapted to slide radially between two cheeks 27, 31 which are fast to a hub 28, which is loose on the axle 42 and driven by a sprocket 19 driven from a pedal chainwheel (not shown). The eccentric has for this purpose a slot 35, Fig. 9, with parallel sides in each of which is a slot 34 inclined at 45‹. The slots 34 are engaged by diametral pins 33, Fig. 10, projecting from a ring 32 which is slidably splined at 32a upon the hub 28. The drive passes through the cheek 27, Fig. 5, and hub 28 to the ring 32 and across from the pins to the grooves 34. The eccentric 3 yields or is moved inwards, and the ring 32 slides to the right of Fig. 5, thereby compressing the spring 55, to which it is connected by plungers 58. When a balance is attained, the drive passes according to the speed ratio position reached.

A method of making moulded elongated articles such as tiles in which the articles 5 are moulded on the face 3 of a rotary drum 2 with their longitudinal axes extending parallel to the axis of rotation of the drum is characterized in that the article 5 is removed from the drum 2 and deposited on a receiving surface 41 (e.g. a conveyer) by means of an article gripping member 22 carried by and reciprocable longitudinally of a rotatable arm 8 which is displaceable between a first position in which the gripping member 22 is juxtaposed to the mould matrix 4 to permit removal of the moulded article 5 and a second position in which the gripping member 22 is juxtaposed to the receiving surface 41. The gripping member 22 is automatically rotated about an axis 7, through an angle of 90 degrees with respect to the arm 8 during displacement of the latter between said two positions so that the article 5 may be deposited on the surface 41 in an orientation different from that of the article 5 on the drum 2. The gripping member may be rotated by means of meshing gear segments, one segment 29 being stationary and the other 28 being rotatable with respect to the arm 8.
