Title: Improvements in or relating to machines or apparatus for cutting vegetables into chips
IPC: B26D7/06
Filed: 1932-06-02
Abstract: 400,705. Cutting vegetables. YOUNG, A. J. M., 11, Nuthurst Avenue, Streatham Hill, London, June 2, 1932, No. 15612. [Class 5 (i).] In a vegetable-chipping machine of the type in which vegetables are deposited in a receptacle or feeding chamber 1 and are forced by means of a plunger 2 against a grid or set of knives, the receptacle or feeding chamber is of substantial V-form in cross-section and one or both of the longitudinal sides 3 thereof is or are so formed that when a vegetable is introduced into the receptacle from the top thereof its movement down one of the side is o impeded that, instead of the vegetable being precipitately deposited, it is caused to make a rolling motion. The plunger 2, actuated manually or by a connecting- rod 6 from a flywheel, reciprocates on guide rods 8 and is provided with an extension 9 accommodated in a gap 10 in the bottom of the receptacle 1, the extension 9 having shoulders 11. The grid or set of knives is set in a square frame bolted to the supports 4 and may be turned through 90‹ to present a new series of knife edges. The sides 3 may be stepped, as shown, corrugated or composed of rods, the plunger in each case conforming to the transverse section of the receptacle.

Title: Improvements in or relating to keysender telecommunication systems
IPC: H04M1/515
Filed: 1955-05-31
Abstract: 776,701. Automatic exchange equipment. SIEMENS & HALSKE AKT.-GES. May 31, 1955 [May 31, 1954], No. 15613/55. Class 40 (4). In an arrangement for signalling digits over a pair of wires from a keysender to a receiver, during the transmission of each digit different voltages are automatically applied in succession first to one wire and then to the other, a different combination of six code relays being operated in the receiver for each digit. A suitable keysender is shown in Fig. 2, digits " 1 " to " 8 " being sent by closing contacts T1 to T8 respectively, and "9" and " 0 " by opening T9 and T0, respectively; the receiver being shown in Fig. 1. Removal of the handset at the substation results in closure of hook switch HV (Fig. 2) whereupon A (Fig. 1) pulls up to the loop including the instrument TN, and C follows and locks up. Depression of a key, say T4, changes over contact P (Fig. 2), the momentary breaking of the loop releasing A, whereupon B pulls up and switches the line through to certain of the receiver code relays. The relatively small negative potential U1 is thus connected via code relay K to the a wire, but, with Gl5 (Fig. 2) in its high resistance state, K remains down. The sensitive relay S (Fig. 1), however, comes up in series with R (Fig. 2), (which remains unoperated), and brings up code relay X1 (Fig. 1). After a delay (sufficient to allow operation of K, if appropriate) relay V1 pulls up, thus connecting the relatively large negative potential U2 to the a wire via code relay L. Relay R (Fig. 2) operates and shortcircuits its high-resistance winding RI, whereupon L pulls up in series with RII. Relay V2, energized by V1, then comes up and applies potential U1 via code relay M to the b wire. M pulls up (in series with Gl5) and S re-operates to bring up code relay X2. Relay V3, energized by V2, then operates applying U2 to the b wire via code relay N, which operates. Relay V4, energized by V3, then pulls up and releases B, whereupon A reoperates to bring up E. This disconnects V4 and the holding windings of the code relays K, L, M, N, XI, and X2. When the key T4 is released, A again restores and Q operates to disable B; reclosure of the loop re-operating A and releasing Q in readiness for the reception of the next digit. After the sending of all the digits, the contact g (Fig. 1) is opened by means not shown and the receiver is released. A further embodiment is described using three voltages instead of two, and in a modification the contact of relay R is replaced by a cold cathode tube and the high-resistance winding of R by a high value resistor, the lowresistance winding of R being omitted.

Filed: 1919-06-24
Abstract: 145,973. Parnell, W. E., and Aeolian Co. June 24, 1919. Right to Patent Relinquished. Feed-motions; driving.-In making a master gramophone record, the blank is mounted on a turntable which moves on a pivoted arm of length equal to that of an average tone arm, i.e. about 8 inches, so that the path of the cutting-tool is similar to that of the stylus on the reproducing- machine. As shown in Figs. 1 and 2 (which latter is a section on A-A, Fig. 1), the motor 7, running at a constant speed, is connected by means of a spiral gear 9 to a gear-wheel d, which reduces the speed to one half, and then through the gear e to gear f on turntable spindle b. The gear d also conveys motion through a series of gear-wheels on the shaft j, Fig. 2, which are arranged so that pitches of various amounts can be used in the preparation of the record. The selected gear-wheels are put in operation by means of the handle u, rod v, pinion w, rack x, and fork y, which moves striker s and key r. The motion is transmitted by the selected gear to the sleeve i carrying a gear-wheel h, and through the gear-wheels k and l to the worm n, and thence to the worm-wheel m on the shaft o. This latter carries a further worm p which operates a circular rack q mounted on the turntable bracket g. For fine adjustment of the starting-position, a cone fitting 6 is introduced in the shaft o so that on releasing it the .shaft can be operated by the hand-wheel 10. To return the turntable to its starting position, a handle 11 removes a registering stop 12, and enables the shaft o to be turned about the axis of wheel m so as to disengage the worm p from the rack g and thus permit the turntable arm to be swung into any position. The sound-box is mounted on an arm z, as shown in Fig. 4. Lateral adjustment of the sliding carriage 1 is provided for in the slot 2, and vertical adjustment of block 3 can be made by a screw 4, the recorder being clamped to the block 3 by screw 5.

Abstract: 515,367. Hydrocarbons ; motor fuel. TEXACO DEVELOPMENT CORPORATION. May 30, 1938, No. 16092. Convention date, June 18; 1937. [Class 2(iii)] Saturated hydrocarbons of gasoline boiling range or higher, suitable for motor fuel are obtained by bringing in liquid phase an excess of low boiling isoparaffins together with olefines into contact with strong sulphuric acid,- separating the alkylation products and recycling at least part of the unreacted isoparaffins. In the Fig., an oienne, e.g. propylene or a cracked gas containing butylenes and an isoparaffin, e.g., isobutane are forced through pipes 3 and 7 respectively into a mixer 4 containing sulphuric acid. The reaction mixture is passed to a separator 18 in order to separate the acid, which may be recycled. The oil which is produced is withdrawn through pipe 34 and passed to a neutralizer 25 containing caustic alkali or other neutralizing agent. The oil, after being allowed to settle in settling tank 33 is passed to a fractionator 41 from which a motor fuel fraction is withdrawn through pipe 44. Products of higher boiling point are removed through pipe 45 and the motor fuel is passed to a stabilizer 48 in order to separate low boiling hydrocarbons, which are recycled after passing through a condenser 52. Examples also describe the reaction when conducted in an iron reaction bomb or other reaction vessel. Specification 479,345 is referred to. The Specification as open to inspection under Sect. 91 describes also the use of catalysts such as phosphoric acid, aluminium chloride and bromide and hydrochloric acid. This subject-matter does not appear in the Specification as accepted.
