Title: Improvements in fruit and like peelers
IPC: A47J17/16
Filed: 1928-05-15
Abstract: 302,121. Heumann, M., and Heumann, A. May 15, 1928. Peeling fruit and vegetables.- A fruit or vegetable peeler of the type wherein the fruit is impaled on a screwed spindle b, revoluble and slidable in a bearing, and is peeled by a cutter on a swivelling bracket f, is characterized by the provision of means for preventing the screw b from wearing grooves in its bearing. As shown in Fig. 3, the means comprise rollers i which rotate and wear uniformly. As shown in Fig. 4, the screw b is enclosed in a sleeve k, slidable but non-rotatable in the bearing. The sleeve k has a longitudinal slot l through which a lug m, on the pivoted member e, projects to engage the threads of the spindle b. As shown in Fig. 1, the swiveling bracket f is connected by a link d with the screw b so that, as the screw is fed forwards by the engagement of the pivoted member c with the threads, the bracket f is swung around and stresses a spring h on its pivot g. On disengaging the member c from the screw b, the spring h returns both the bracket and the screw to the initial position.

Abstract: 107,500. Crowley, J. F. Oct. 10, 1916. Tension and supporting arrangements.-Antivibration devices for the driving-belts of suspended electro-motors &c. are provided with means for adjusting the belt tension without altering the adjustment of the springs for counteracting vibration. In the form shown in Fig. 1 the frame of an electro-motor a, for driving a loom, is pivoted at c<1> and supported by springs d, d<1> for counteracting vibration which bear on a lug a<1> on it. The springs are carried by a rod e fixed in a lever f which is adjustable by nuts on a fixed rod g' to vary the tension of the belt b on the driving- pulley b'. In the form shown in Fig. 2, vibration of the belt b is counteracted by springs d, d' which bear on a lever i' carrying a jockey-pulley h, and the tension of the belt is varied by adjusting the position of the rod e carrying the springs by nuts e<1>. In another modification, the tension on the belt is maintained by a weighted lever connected through two antivibration springs with a three-armed lever carrying a jockey-pulley bearing on. the belt.

Abstract: 430,690. Capping bottles &c. ALUMINIUM, Ltd., Canada Life Building, Toronto, Canada.-(Assignees of Hogg, E. E.) May 14, 1934, No. 14520. Convention date, May 13, 1933. [Classes 125 (ii) and 125 (iii)] Bottles, tumblers, &c. are closed by fragile caps, e.g. of flexible metal foil, by resiliently pressing a portion of the cap against the top of the bottle &c. by a single resilient deformable member and simultaneously or immediately thereafter resiliently rolling another portion of the cap downwardly into smooth engagement with the exterior of the bottle finish ; the cap may also be rolled into close conformity with the exterior of the bottle below the finish and with the interior of the bottle. As shown, a glass tumbler 50 is centred or a resilient pad 48 at the base of the cap-applying apparatus by adjustable bolts 45 and the sealing head 26 is carried by a shaft 15 carrying rack teeth 16 engaging a pinion on a shaft 18 actuated by a handle 24 constructed of flexible material with a loop 25 ; the resilient deformable sealing member 38 is retained in a groove 34 in the head by its flange 35 and, when symmetrical about a horizontal centre line as shown, may be reversed in the head when it becomes worn. When the sealing head is lowered the central part 41 of the sealing member engages the cap 52 and compresses it into conformity with the interior of the finish of the tumbler while simultaneously or immediately thereafter the downward movement of the sealing member is interrupted and the downward movement of the head causes the portion 40 of the member to progressively and resiliently roll the skirt of the cap into close conformity with the bead or finish 55 of the tumbler; entrapped air escapes through the apertures 43, 59 in the sealing member and head respectively. The tumbler may have a flared finish and various bottle finishes and caps are also described with sealing members suitable therefor. Specification 430,689 is referred to.

Patent GB-148455-A (GB)
Abstract: 148,455. Kubler, C. May 23, 1919, [Convention date]. Adding and subtracting apparatus; transfer mechanism; zeroizing-mechanism.-In adding and subtracting apparatus of the type comprising numbered slides set differentially and read through numeral openings l in a slotted casing a, the setting-holes g, h and numeral markings arc duplicated on the reverse side so that the apparatus may be used one side up for addition and the other side up for subtraction. By colouring portions of the slides a single rule of operation can bo adopted irrespective nf the particular arithmetical process concerned. Each slide may be in two distinct parts c, d, Fig. 17, connected together and guided by a slotted plate e, Fig. 6, having a central imperforate portion to prevent rupture of the lower slide by the setting-peg. Alternatively, the slide may be of box form produced by bending a metal sheet at r<1> and r, Fig. 20, the closure being incomplete as shown in Fig. 21, so as to give a friction fit in the guides formed in the casing by turning down the tongues produced in making the slots i in the cover plates. The slides may be doubly bent so as to provide a central wall r<2>, Fig. 22, or they mav be constructed of two plates secured together with interposed cloth, leather &c. projecting at the sides to produce friction. The slides may be reset to zero by a sliding plate n, Fig. 17, which may be spring- controlled, have feet o to engage the slides, and be shaped to receive a writing pad p. In a modification, this plate n may be secured to the lower cover plate of the casing which is formed to telescope for re-setting. On each slide, transfer signals m occupy the space corresponding with the numeral 10 on the addition side and the numeral -1 on the subtraction side. Moreover, in order to indicate, when the device is turned over to, say, the subtraction side, that a transfer on the addition side has not been effected' a further signal m<1> is provided at the opposite ends of the numeral scales. In the Specification as open to inspection under Sect. 91 (3) (a) a construction, Fig. 27 (Cancolled), is described whereby transfer may be effected automatically through the medium of a toothed wheel a adapted to be engaged by the setting-stylus when it reaches its upward limit of movement. This wheel meshes with a rack on the next slide to the left, which thus receives the necessary downward travel to the extent of one step. In a further form shown in Fig. 36 (Cancelled), the transfer signals m are continued beyond the 10 and -1 positions, thus enabling the clearing of the transfer signals to be deferred until the end of the complete computation. In this modification, the holes are replaced by teeth, and the slots k are joined up with the main slots i so that the stylus may be readily shifted across from one to the other without withdrawal and reinsertion. The slides may be toothed only along the portions requiring transfer movements, and may have holes in the remainder of their lengths, as shown in Fig. 36 (Cancelled). This subjectmatter does not appear in the Specification as accepted.

Methane-rich gas is made by reacting hydrocarbons boiling up to 270‹ C. with steam at a temperature below 500‹ C. and at superatmospheric pressure in the presence of a nickelalumina-aluminium catalyst. The catalyst must comprise 10 to 60 wt. per cent alumina, 25 to 85 wt. per cent Ni, and a balance of not less than 5 wt. per cent aluminium, and the steam to hydrocarbon weight ratio must be in the range 1-25 to 2-5 to 1. Preferred reaction conditions are 370‹ to 430‹ C. and 15 to 30 atmospheres, and in specific catalysts the Ni content ranged from 43% to 55À4% and the Al content from 15À9% to 21À6%. The make gas may be passed over the same catalyst at below 370‹ C. to increase the methane content, or over a conventional methane-reforming catalyst at 660‹ to 680‹C. to produce a town's gas. Four specific examples are described using as hydrocarbon feed respectively commercial propane, n-hexane, a light naphtha, and a distillate oil.
