Abstract: 1,273,972. Apparatus for topping vegetables. SORTEX-BRETTEN Ltd. May 14, 1969 [Feb. 16, 1968], No.7703/68. Heading A4C. Apparatus for topping elongated vegetables, such as carrots and parsnips, comprises an elongated linear conveyer, having two moving, spaced, endless wires 1, for feeding vegetables, "crown first", to a transverse stop 4, 9), a transverse vertical blade 12 with an inclined lower cutting edge 13 located adjacent the downstream end of the conveyer and upstream of the stop, a cradle 14, 15, having a part 14 narrower than the spacing of wires 1 and located normally below a top run of wires 1, the cradle being on one end of a lever (16, 18), Fig. 2 (not shown) movable by a driver (20), Fig. 2 (not shown), actuated by a detector responsive to the proximity of a vegetable with the stop, for moving a vegetable, abutting the stop against the blade to severe the vegetable crown 10. Driver 20 is a solenoid actuated via a variable-delay relay by a photo-electric device 22, 23 between blade 12 and the stop, the stop comprising a pivoted plate 4, adjustable in position by a screw 7, with spaced wires 9 extending upwards from the plate edges, the wires 9 abutting against the vegetable on either side of a central part 11 of its crown 10. The topped vegetable is directed into a receiver by a guide (21), Fig. 2 (not shown). Topped vegetables may be selectively directed according to size to one of a plurality of receivers by deflectors selectively operated by a series of photo-electric sensors 25 detecting the vegetabletail position as the crown abuts stop 4. In an alternative embodiment, Figs.3 and 4 (not shown), the solenoid delay relay system is actuated by a biassed micro-switch (27) with an actuating lever (28) momentarily engaged by each vegetable, and the stop comprises a plate (31), Fig. 4 (not shown)having a slot(32) into which acrowncentre 11 can pass. The plate (31) is located on a hood (29) of a suction duct (30), blade 12 being fixed to hood (29) above plate (31). Suction through duct (30) from a fan tends to hold a vegetable against plate (31). During topping, the cradle moves the vegetable-crown across the downstream side of blade 12 within hood (29), the severed crown falling down duct (30).

The part 9 is mounted at the end of a shaft 3 adapted to be moved forwards by a hand-lever 4. As the shaft is retracted by the action of a spring 25, the grippers 13 are opened by contact with a fixed part 19. A stop-ring 27, adapted to be adjusted in position on the shaft 3, prevents the can from being pressed too far forwards.
Patent GB-439010-A (GB)
Title: Improvements in and relating to date indicators
IPC: G04B19/257
Filed: 1935-03-14
Abstract: 439,010. Date indicators. CHIRNSIDE, H. S., Westholme, Winsford, Cheshire. March 14, 1935, No. 7900. [Class 106 (iv)] A date indicator is advanced by manuallyactuated or clock-actuated means which advance day-name and date-number drums and also drive a ratchet wheel connected to a wheel having cams spaced distances apart corresponding to the numbers of days in the different months, the cams controlling a device for advancing the month drum and for moving the date-number drum to its starting position at the end of months having less than thirty-one days. In the manuallyactuated form shown, a knob 10 is depressed once every day and, by acting on an arm 9, rocks a shaft 8 to which is attached another arm 32 connected by a link 37 to a pawl engaging a ratchet wheel 40, Fig. 1, on the day-name drum 6. An arm 31 is also secured to the shaft 8 and is connected by a link 33 to a pawl 34 engaging a ratchet wheel 36 secured to the date-number drum 4. A further arm 12 on the shaft 8 is connected to a pawl 14 which drives a wheel 15 having 366 teeth. This wheel is integral with the wheel 16, Fig. 4, provided with cams spaced peripherally in accordance with the numbers of days in the months. At the end of a month a pawl 18 falls over the point of a cam and allows a shaft 26 to rock. This shaft has an arm 28 carrying a pawl 29 which drives the month-name drum 5. The shaft 26 is also provided with another arm 27, Fig. 2, carrying a pawl 47 which can engage a gap 46 in a disc secured to the date-number drum. If the month has less than 31 days, the pawl 47 advances the date-number drum to the required distance at the end of the month so that it may indicate " 1 " on the first day of the following month. To allow for leap year, the wheel 15 is advanced an extra step during February in a non-leap year by a pawl 25 carried on an arm 24, which can fall into three notches 23 on a disc so geared to the wheel 15 that it rotates once in four years. During February of every fourth year, no notch 23 comes opposite finger 24 and thus the operating knob 10 can be depressed 29 times and the drum 4 can indicate " 29 " before the pawl 18 falls over a cam on the wheel 16. The wheel 16 may be connected to a counter which indicates the year number. In a modification, leap year is allowed for by providing the wheel 15 with 1461 (= 3x365+366) teeth and allowing it to rotate once in four years, the wheel 16 then having 48 cams spaced according to the number of days in the months of a four-year cycle.

Abstract: 447,703. Operating mechanism for railway &c. points. KERSHAW, A. G., and WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., 82, York Road, King's Cross, London. March 16, 1935, No. 8256. [Class 104 (i)] Mechanism for operating railway &c. points, comprising locking mechanism for retaining the points in adjusted position and adapted to unlock them automatically when they are trailed through, comprises three relatively rotatable elements 2, 6, 7, the element 2 being rotated by the point-setting motor &c. through the shaft 1. During this movement the locking member 13 corresponding to the existing position of the points is moved by a cam face 3 on the disc 2 out of operative engagement with a face 11 on the locking element 7. After a certain lost motion, a face 41 on disc 2 engages a stud 141 on the driven element 6 which operates the points by rack-and-pinion. When the element 6 moves, it turns the locking element 7 by means of a spring 9 mounted between abutments 8, 10 on 6 and 7 respectively, and when the points are fully set, a face 11<1> on the element 7 is engaged by another locking member 13. When the points are trailed through, the element 6 is first rotated by the displacement of the points, compressing the spring 9 and turning the disc 2 by engagement between the stud 14 and the face 4 on the disc. The face 3 then moves the locking member 13 out of contact with the face 11 on the locking member 7, thus releasing the element 6 and permitting continued movement of the points. In another form, the locking element comprises two parts, one of which is connected to the driven element 6 through the spring 9 and the other part for one direction of rotation of 6, while the latter part of the locking element is connected to 6 through the spring and the first part for the other direction of rotation of 6.

Title: Improvements in and relating to engine starters
IPC: F02N7/02
Filed: 1939-03-15
Abstract: 526,434. Turning-gear. CRILEY, W. C. March 15, 1939, No. 8336. Convention date, March 31, 1938. [Class 7 (v)] An engine starter comprises means for storing further energy in a normally compressed gas and means for releasing the further energy and transmitting it through an incompressible fluid to a part which is held against movement while the energy is being stored. In the form shown, a body of liquid is maintained between pistons 2, 8, 29 in communicating cylinders 1, 7, 27. The starter piston 8 is urged to the left by a spring 22 and is normally held against movement to the right by a detent 23 carried by a rotatable shaft 25. The cylinder 27 contains at the right-hand end gas which is normally compressed and which can be further compressed by rotation of a screw 3 forcing the pump piston 2 to the right-hand end of the cylinder 1. When a sufficient pressure is reached, a spring-loaded piston in a cylinder acts through a rod 37 and lever 45 to engage a pinion 10 with a rack 9 on the starter piston 8 and to bring into engagement a starter clutch 15. The detent 23 is also released by means of a lever 41 and the starter piston 8 is actuated by the gas pressure in the cylinder 27 and drives the engine shaft 17 through the rack and pinion 9, 10 and the clutch 15. If the piston in the cylinder 35 is removed or the rod 37 disconnected, the lever 45 can be operated manually through a cable.

Patent GB-601307-A (GB)
Title: Improvements relating to liquid projection apparatus
IPC: F41H9/02
Filed: 1944-05-04
Abstract: 601,307. Liquid discharging apparatus ; fire-extinguishing. FRASER, R. P. May 4, 1944, No. 8484. [Classes 47 (ii) and 119] [Also in Groups XI and XXVIII] Relates to liquid projection apparatus of the kind in which liquid supplied under pressure to the interior of a barrel or the like 9 is projected from the barrel nozzle 18 when a control valve 10 normally obstructing said nozzle recedes, and in which a supplementary liquid is simultaneously supplied under pressure as a sheath or envelope around the main liquid. According to the invention the control valve is arranged to reciprocate as a piston in a hollow guide chamber 11 into and from which the supplementary liquid-passes on its way to the barrel nozzle, and serves as a force pump with respect to the outflowing supplementary liquid as the said valve performs its receding movement to permit discharge of the main liquid. The main liquid may be highly inflammable and the supplementary liquid be non- inflammable or less inflammable as described in Specification 583,023, or the supplementary liquid may form an inflammable sheath around a core of extinguishing main liquid as described in Specification 589,034. In a rigid vessel 1 containing the main liquid is immersed a collapsible vessel 3 containing supplementary liquid. Both can be expelled by compressed air or gas stored in a cylinder (see Grou XXVIII). To actuate the apparatus a valve 17 is opened and supplementary liquid passes past a. normally open valve 15, through chamber 11 along an outlet pipe 21, past a non-return valve 22 and into an annular space 0 in the nozzle. The main liquid discharges through the centre of the nozzle as soon as the pintle 10 has receded. Immediate further manipulation of the controls closes the valve 15, keeping 17 open. The supplementary liquid, although deprived of driving pressure from 3, continues to escape since the pressure of the main liquid on the shoulder 10a of the pintle valve 10 drives the valve rearwardly so that it expels the supplementary liquid. To stop the action valve 15 is opened and the pressures on each side of the pintle 10 are equalized. A spring 12 then closes the pintle valve and the initial conditions are restored upon closing valve 17. The supplementary liquid is ignited by a spark gap or hot wire 26, valve chamber 24 having a fine orifice through which some liquid can escape to the igniting means.
