Title: Improvements in machines for peeling potatoes, apples and the like
IPC: A23N7/02
Filed: 1927-01-18
Abstract: 264,836. Borer, P. Jan. 19, 1926, [Convention date]. Peeling potatoes, apples, &c.- In a machine for peeling potatoes, apples, and the like, the potatoes &c. contained in a hopper 1 are dropped one by one on to pronged supports 3 mounted on a turntable 2 by which they are carried past resilient peeling-knives to a discharge device which delivers them to a shoot 18. The hopper 1 has a bottom closure 1<b> movable in a horizontal plane on a hinge 1<d> associated with a torsion spring 1<e> which tends to keep the hopper closed. The closure 1<b> has a depending pin 1<c> which contacts with pins on the table 2 whereby a potato is released whenever a support 3 is positioned to receive it. The knives are carried in groups on arms 7 - - 10 on a central stationary shaft 2a and are arranged as shown in Fig. 6, the cutting edges 11<a> of the rear row of blades 11 registering with the gaps in the front row. The knives a- - d are arranged to operate on the potato at different angles and, during the rotation of the table 2 the supports 3 are revolved slightly by the engagement of pins 12 with teeth formed on the support 3. After passing the knives a- - d the supports 3 are revolved sufficiently to permit a set of knives to peel one end of the potato. The toothed parts of the supports 3 then engage a toothed stop to present an entirely fresh surface to another group of knives which peel the potatoes entirely except for the portion concealed by the supports 3. The discharge device comprises two stationary discs 13 having ramp 13<a> at their upper portions which engage and separate spring-pressed forks 16 carried by arms 15 on a rotary shaft 14. The lower parts of the discs 13 are cut away to allow the forks 16 to come together and enter the potato which is thereby lifted from the platform 3, then in the discharge position, and carried by arms 15 to the shoot 18. The unpeeled part of the potato is peeled during this movement by an auxiliary set of knives, and the forks 16 are then withdrawn by the ramps 13a allow the potato to fall into the shoot 18. The table 2 is rotated by toothed gearing 4, 5, 6.

Title: Improvements in model railways
Inventor: SOMMERHOFF GERD WALTER CHRISTI
IPC: A63H19/24
Filed: 1954-01-20
Abstract: 759,186. Model electric railways. LINES BROS.. Ltd. Jan. 20, 1955 [J an. 20, 1954; Feb. 16, 1954], Nos. 1651/54 and 4460/54. Class 132(3) A locomotive of a model electric railway has a member movable downwards by an electromagnetic device operable by a momentary increase in the voltage normally supplied to the locomotive from the track, the member being engageable with at least one element, e.g. a points-operating tongue on the track. In Fig. 1, a locomotive is propelled by an electric motor having an electromagnet 9 connected in series with it, and a headed plunger-like member 3 normally urged upwardly by a spring 5 is depressed by an armature extension 7 when the voltage to the locomotive is increased, e.g. by a surge from a discharging capacitor, the armature 8 then being held in its attracted position by the electromagnet energized by the current supply at its normal voltage. Fig. 2 shows points having a movable rail member 14 secured to a pivot pin 17 which in also attached to a Y-shaped bar 18, Fig. 4, an operating tongue 22 being pivoted to the bar 18 and supported by a wire 24 anchored at one end in the base of the points. When the locomotive approaches the points in the direction X, Fig. 2, with its plunger 3 lowered, the points are changed, whatever their setting, by the plunger riding along one side of the tongue, a ramp 26 then forcing the plunger 3 upwards against the magnetic attraction of the still energized electromagnet. To ensure the points being set correctly when the locomotive approaches in the directions Y, Y<SP>1</SP>, vanes 27, 27<SP>1</SP> provided on the arms of the bar 18 and projecting upwardly through holes 28, 28<SP>1</SP> are adapted to engage the plunger 3 of the locomotive. Ramps 29, 29<SP>1</SP> urge the plunger upwardly after it has passed the vanes. Fig. 5 shows how current is fed to the track 2 from a transformer 31 via a rectifier 32 and variable resistance 39 which acts as a motor speed regulator. A second circuit includes a capacitor 37 which is normally charged from the mains supply via resistors 33, 34, rectifier 35 and switch 36 which when changed over causes the capacitor to discharge and the electromagnet 9 to be actuated. In a modification (Fig. 6, not shown) the extra voltage for actuating the electromagnet is obtained from a tapping on the secondary winding of the transformer.

Title: Data Storage Apparatus
IPC: G11B21/08
Filed: 1968-01-12
Abstract: 1,194,121. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORP. 12 Jan., 1968 [16 Jan., 1967], No. 1864/68. Heading G4A. In data storage apparatus, data is recorded in tracks at both edges of separate opaque stripes arranged in a frame on a substrate, a radiation spot being scanned along any track, modulations of the spot by the recorded data being detected, and loss of the modulations at the margin of the frame causing the direction of scan to be reversed and scanning of an adjacent track to be initiated. Parallel horizontal data tracks recorded on photographic film each consist of a line of bits, a 1 bit being a transparent space followed by an opaque space and a 0 bit being the reverse. Each even numbered track is separated from the preceding track by an opaque strip and from the succeeding track by a transparent strip. As a spot of light from a cathode ray tube is scanned along a track, a data photomultiplier, fed by the light transmitted through the film, provides data output and feeds a tracking servo unit (which also receives the output of a reference photo-multiplier). The tracking servo unit controls the C.R.T. vertical deflection voltage to keep the spot on the track, by responding to the average grey level to move the spot up or down in the case of even and odd numbered tracks respectively in the case of too much light, and in the opposite directions in the case of too much dark. After the end of the track is reached the fact that the horizontal deflection voltage of the C.R.T. lies outside certain limits in conjunction with detection of three consecutive missing bits reverses the direction of change of the horizontal voltage, reverses the "sense" of the tracking servo unit and permits either a positive pulse generator or a negative pulse generator (depending on which end of the track the spot is at) to be actuated by the controller. The controller will attempt to so actuate if an opaque strip has to be jumped to get to the next track. Thus the controller selects the next track above or the next below that just scanned. The positive or negative pulse is added to the horizontal deflection voltage so that the spot will move to the appropriate next track. The positive and negative pulses show a step then a gradual return which lasts during the scanning of the track. Specification 1,161,102, is referred to for details of some aspects. An electron beam may be used for read-out in place of light.
