Abstract: 797,143. Coin-freed vending apparatus. PURRETT, J. W. Feb. 15, 1957 [Nov. 15, 1955], No. 32585/55. Class 27 A coin-freed machine dispenses postcards 11 or like articles from a criss-cross stack arranged in a magazine 12 by rotating either the magazine, or a base 14 with an aperture 23, through 90 degrees by means of a handle 30 connected to a lazytongs linkage which is arranged to lie wholly clear of the delivery aperture when in either of its extreme positions. As shown, the apertured base 14 is in the form of a turntable connected by the lazy-tongs 36, 35, 33 to the handle 30 and the handle is also connected to a channel-section slide 42 having a pair of slots 46 registerable at each end of the travel of the handle with an external coin slot 27. Insertion of a coin in one of the slots 46 disengages a catch 39 from one of a pair of abutments 38 on the turntable 14 and on rotation of the turntable a pair of segmental supports 24 are removed from beneath the lowermost card, thus releasing it through the aperture 23, and move into support position beneath the card immediately above, ready for a further dispensing operation by a reverse rotation of the turntable. A full-stroke pawl 50 co-operating with pegs 49 ensures full movement of the handle 30. On removal of a front panel, the catch 39 can be released by depressing a pushbutton. Initial movement of the handle moves the coin clear off the catch 39 and off a supporting ledge 47 and as the turntable completes its movement the catch rides over the inclined back of an abutment 38 into locking position. The magazine is preferably made of hardboard secured to wooden corner posts 13 that form an internal cruciform section.

Title: Improvements in or relating to dry process of fractionating milled cereal flour stocks
IPC: B02C9/00
Filed: 1955-11-17
Abstract: Two cereal flour products are obtained from a parent flour consisting of a mixture of heterogenous particles, some consisting principally of starch, others principally of protein, by air fractionating the parent flour at a cut within a range of F.D. units (defined) that one of the products has a higher protein content whilst the other has a lower protein content, both relatively to the parent.  The parent is selected from the group; wheat, rye, corn, barley and rice flour, and the cut used varies according to the parent flour.  Critical cuts are given both for protein concentration, and for protein and ash depletion in the coarse fraction.  The initial coarse fraction can be further fractionated the obtained fractions being again fractionated or the resulting coarse fraction combined with the initial fine fraction.  Similarly, fractions from different level cuts can be combined.  Specification 789,274 [Group II] is referred to.

Patent GB-604860-A (GB)
Title: An improved slushing composition
Filed: 1945-12-06
Abstract: Slushing compositions for application to bright ferrous surfaces of machines to protect them against rust during storage and shipment comprise a mineral lubricating oil or a waxy solid petroleum product such as petrolatum, a solvent, e.g. white spirit, and a minor proportion of a partial ester of a monocarboxylic fatty or naphthenic acid and of a straight chain aliphatic polyhydric alcohol or partially dehydrated alcohol of this type.  A fatty material such as animal or vegetable fats, waxes or fatty oils may also be present. The partial ester may be a mono-ester of glycol, or a mono- or di-ester of glycerol, of erythritol, of pentaerythritol, of arabitol or of a partially dehydrated hexitol and the acid radical of the ester may be oleate, erucate, naphthenate, laurate, stearate, palmitate, or a mixture of fatty acid radicals derived from a naturally occurring animal or vegetable oil or fat.  The proportion of partial ester may be 0.5 to 10 per cent by weight of the non-volatile portion of the composition which may, for example, consist of about 80 per cent by weight of solvent, 10 per cent of wool grease, 8 per cent of mineral lubricating oil and 2 per cent of the partial ester. The partial esters may be prepared by reacting one mol. of the polyhydric alcohol or of the partially dehydrated polyhydric alcohol with one or two mols. of the monocarboxylic acid or monocarboxylic acid mixture either in the presence or absence of a catalyst.  Catalysts such as sulphuric or phosphoric acids or sodium hydroxide may be used.  The reaction may be carried out at a temperature of 150-300 DEG  C. in a closed kettle fitted with a stirring gear, an inert gas such as nitrogen or carbon dioxide being preferably passed through the mixture in order to assist in the removal of the water formed and to prevent discoloration of the esters.  Methods for the preparation of partial esters of partially dehydrated polyhydric alcohols have been described in U.S.A. Specification 2,322,820.

Title: Improvements in or relating to electric circuit-controllers
Inventor: NASH JAMES GENTLE
IPC: H01H43/12
Filed: 1957-10-23
Abstract: 868,811. Time switches. McCORQUODALE & CO. Ltd. Oct. 21, 1958 [Oct. 23, 1957], No. 33137/57. Class 38 (5). A device which operates on a time basis to control a number of circuits automatically at predetermined intervals, comprises a row of helically grooved metal bobbins 15 mounted on a shaft 12 which is rotated in uprights 14 by an electric motor 11 and reduction gearing 13. Each bobbin controls a switch 19 by means of helical metal rods 37, whose lengths and positions in the bobbin groove may be varied to obtain any desired switching sequence, Fig. 4 (not shown). These rods engage an actuator 22 to close the contacts 21 of spring blades 20, which are secured to a bar 16 mounted on a bracket 29. Each end of this bracket has a lug 30 pivoted at 17, 18 to the uprights 14, the lug pivoted at 17 having an extension 31 connected by a spring 32 to an arm 25. Springs 33, 35 resiliently secure the bracket 29 to a cross-bar 34 and stops 36 engage the bracket ends. The arm 25 is pivoted at 26 and has a part-circular lead screw, which normally is coupled to a thread 24 on the shaft 12 by the pull of a spring 27, the pitch of the thread 24 being equal to that of the bobbin grooves. This coupling causes the shaft 12, upon rotation, to move to the right, this movement being permitted by slots 45 in the shaft and opposed by a spring 42. In operation the shaft 12 moves from its extreme left position to produce a desired switching sequence and on completion a disc 46 engages first a switch roller 47 to indicate such completion, and then a switch roller 48 to stop the motor 11, the shaft and bobbins stopping in the same angular position in which they started. A lever 28 on the arm 25 is now raised to rotate bracket 29 and lift switches 19, and allow spring 42 to return members 12, 15 to their starting position. The rods 37 may be soldered to the bobbins 15, or if sufficiently long, may form resilient clips sprung into the groove of the bobbin. If desired the rods 37 may form moving switch contacts which engage the conducting brush of a single stationary switch blade.

Abstract: 815,971. Piston packings. REGIE NATIONALE DES USINES RENAULT. Nov. 22, 1955 [April 26, 1955; June 23, 1955], No. 33476/55. Class 122 (1). [Also in Group XXIX] A seal between a sliding rod or piston and a cylinder containing fluid under pressure comprises a packing ring having an annular body 16, Fig. 5, which is placed under tension in a groove 17 in the rod or piston so that it ensures fluid-tightness along several spaced surfaces of contact with the groove and is of such outer diameter that it forms a guide bearing between the rod or piston and cylinder, and a tapering lip 18 which is connected with the body by a portion 31 thinner than the adjacent part of the lip and applied under tension against the inner wall of the cylinder. Instead of being of circular cross-section as shown in Fig. 5, the annular body may be of substantially square or rectangular cross-section, in which case it may engage against ribs 32, 34, 33 formed on the bottom and one side face of the groove as shown in Fig. 6 and one of its end faces may be recessed to co-operate with the rib 34. The reduced neck portion between the annular body and lip is provided by forming a groove 31 on either the inner or outer face of the ring. In the construction shown in Fig. 3, the packing ring opposes the passage of fluid from the chamber 21 to the chamber 22 as the piston enters the chamber but peripheral grooves 24 in the ring permit it to act as a valve and allow fluid to pass from the chamber 22 to the chamber 21. Two packing rings of the kind shown in Fig. 3 may be arranged in opposed and spaced relation on a single piston (Fig. 4, not shown).

Title: Roll feeder for excavating wheel
Inventor: KOLBE FRANK FREDERICK
IPC: E02F3/24
Filed: 1959-10-05
Abstract: 863,671. Excavating earth. UNITED ELECTRIC COAL CO'S. Oct. 5, 1959 No. 33698/59. Class 68(1). [Also in Group XXX] In a roller conveyer for receiving earth dropped from the inverted buckets on a rotary bucket excavating wheel, and for removing it to a discharge conveyer, the rollers are rotated to give a peripheral speed which increases from roller to roller from the inside to the outside of the bucket wheel. The progressive increase in peripheral speed may be attained by rollers of progressively increasing diameters being rotated at the same angular speed, but as shown, rollers 41 - 44 of the same diameter are rotated at progressively increasing angular speeds. The differential speed lessens damage to the rollers due to attrition and shock from rocks &c falling from the buckets on to the rollers. The bucket wheel 12, roller conveyer 41 - 44, and belt conveyer 26 are mounted on a vertically adjustable and horizontally oscillatable boom 10. The buckets each have a flexible mat-like wall 18 which may flex downwards, when the bucket is inverted, to facilitate discharge of the earth. The open sides of the bucket are closed during the ascent to the inversion position, by a stationary plate 30 which may carry a plate or plates 31 to close the gap between the roller 41 and the back wall 20 of the bucket wheel, and to protect a gear box 60 which drives the rollers 41 - 44. The rollers are driven by a motor 46 through reduction gearing 48, chain drive 50, clutch 52, universals 56, shaft 54 and a shaft 58 driving the roller 44 directly and carrying a gear wheel 104 which transmits the drive to the other rollers. The shaft 58 is journalled in a gear box 60 and has a flange 62 which is connected by a split collar 64 to a flange 66 on a stub shaft 68 on which is secured a member 70 having radial projections which are received with large clearance in recesses in a member 72 attached to the inside of the roller 44. The clearances are filled with cushioning pads to prevent transmission to the gear box 60 of shocks and jars experienced by the roller. The other rollers 41 - 43 are similarly driven through shock absorbing means, the gear 104 being meshed with an idler 107 which meshes with the gear on the shaft 58 of the roller 43, the rollers 42, 41 being driven similarly through interposed idlers. The idlers are of the same diameter and the gears on the shafts 58 increase in size to produce the required differential speeds. End member 70 has a spherical bearing surface 75 for rings 76 so that each roller may flex and yield under undue strains, the other end of the roller having a pillow block bearing 80. A raised bead 110 of wear-resistant material is provided on each roller, e.g., of welding rod in helical form, which encourages the build-up of a thin layer of earth material which protects the rollers. The beads also scrape adjacent rollers and prevent excessive accumulations. Specification 749,105 is referred to.
