Abstract: 956,028. Separating sprouts from their stalks. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 14, 1963 [Dec. 27, 1961], No. 46244/61. Heading A4C. In an apparatus for stripping sprouts from their stalks, rollers 15 grip the stalk and draw it through abutment means, e.g. board 10, which permit the passage of the stalk but not of the sprouts carried thereby so that the sprouts are broken off. Sprout plants are manually fed through a feed tank 12 for an aperture 11 in the board 10 to be gripped between the slowly rotated rollers 15, the sprouts being broken off by abutment with the board 10 to fall into a shoot 21. The rollers 15 are adjustably urged towards each other by a spring 17 and screw 18. Small sprouts and leaves are removed from the top of the stalks prior to feeding through the aperture 11 by pushing the plant top into a smaller aperture 22 provided with a sharpened piping 23.

Title: Continuous flow thick-film centrifuges
IPC: B04B3/00
Filed: 1972-10-06
Abstract: 1412006 Centrifugal filter K PAUSE 6 Oct 1972 [15 Oct 1971] 46324/72 Heading B1D A continuous flow sugar centrifuge comprises: (i) a centrifuge drum 1 having axially inclined walls so that it is wider at its open end; (ii) a similarly shaped screen or wirebasket 9 fixed within the drum for rotation therewith; (iii) inlet means 21 for introducing suspension to the narrow end of the drum interior; (iv) a disc 25 arranged outside the wider end of the drum and defining therewith an annular gap 26 for the discharge of solid material; (v) outlet means 5, 7 for discharging liquid from the drum; and (vi) an axially displaceable annular metering ring 31 having a conical inner surface disposed around the annular gap 26 for determining the rate of discharge of solid material therethrough. The drum interior and screen are stepped 9, 11. The rate of flow of suspension into the drum is controlled by raising or lowering conical baffle 17 into the interior of which suspension is led by pipe 21. The lower liquid outlets 5 are for "green syrup" whilst the upper outlets 7 are for "high green syrup". A washing water nozzle 22 having feed pipe 23 and a film thickness control means 24 also extend into the drum interior. The metering ring 31 has a conical inner surface and is attached to a further disc 33 of magnetisable material, this further disc being mounted on the side of disc 25 remote from the drum for reciprocal axial movement between stops 29, 30 on disc 25 and is secured for rotation with disc 25 by spring members 36 which urge the two discs towards one another. Disc 25 is itself mounted fast for rotation with the centrifuge drum. An electromagnet 39 is mounted above the disc 33 and attracts that part of the disc directly therebelow with the result that as the drum and discs rotate, each portion of the disc 33 is sequentially attracted towards the magnet 39. The free axial mounting of this disc between stops 29, 30 and the spring connectors 36 allow the disc 33 to have an overall eccentric or axially variable movement relative to the drum and disc 25 as it rotates and thus has the effect of pumping out a constant quantity of sugar per unit time.

Title: Pressure differential switch and a warning device incorporating  such a switch for a vehicle braking system
IPC: H01H35/38
Filed: 1972-10-10
Abstract: 1357834 Brake circuit failure warning devices DEUTSCHE BENDIX AUSRUSTUNGS GmbH 10 Oct 1972 [28 Oct 1971] 46675/72 Heading F2E A differential pressure warning switch comprises a housing in which a floating pressure responsive assembly is sealingly mounted defining at each end a pressure chamber connected to one circuit of a dual circuit braking system, the assembly comprising two pressure responsive elements corresponding with the chambers and co-operating with corresponding motion transmitting members, biased by resilient members towards abutments fixed in the housing defining positions when the elements are not acted upon by pressure, the members having mutually facing abutments which are engageable when the elements are pressure actuated. When the brakes are not actuated, the pressure responsive elements, which are either pistons 18, 20 (as shown) or diaphragms, are at rest (as shown). The motion transmitting members 38, 40 are held apart by springs 54, 56 which abut a reaction bar 62. The members 38, 40 have radially enlarged heads 88, 90 at their inner ends having electrically conductive plates 42,44, which, in the rest position, provide connection between pairs of contacts 76, 78 and 84, 86. Since there is no connection between two contacts 80, 82, associated circuits, Fig. 8, are not connected to a battery or other power Source 116. Upon normal brake actuation, both members 38, 40 are moved inwardly against the springs 54, 56 so that their contact plates 42, 44 both engage the contacts 80, 82. This affords connection between the source 116 and a brake light 118 which is energized to indicate braking. If, however, one of the brake circuits fails, the corresponding member, say 38, cannot withstand the forces on the other member 40 which continues to move leftwardly until it engages the first member 38 to push member 38 back to its rest position. The contact plate 44 of member 40 stays abutting with contacts 80, 82, as it is resiliently held on the member 40, but the other plate 42 is moved to engage the contacts 76, 78. As shown in Fig. 8, when one outside contact pair and the centre contact pair 80, 82 are connected, a failure warning lamp 120 is energized. As shown, one lamp 120 provides a failure indication for either brake circuit; alternatively a separate lamp for each circuit may be provided. Upon brake release, the extended member 40 is held in that position by engagement between a spring ring 106 and a chamfer 110 to provide continuous failure indication. The reaction bar 62 is rotatable a small extent to lock the members 40, 38 apart during bleeding operations.

Abstract: 1281027 Frames for handling freight containers KAMEL PRODUCTS Ltd 24 Sept 1970 [2 Oct 1969] 48523/69 Heading B8H A lifting frame comprises two side members 1 and two end members 2 joined at four corners where turnlocks 3 depend for releasable attachment to a freight container. The frame is suspended by four wires 5 each rove about a corner sheave 4, passing along a side member 1 and terminating in a non-rotatable screw threaded into a rotatable nut otherwise not movable with respect to the member 1. The frame is rendered self-levelling by operation of an appropriate switch (35) in a control circuit, Fig. 4 (not shown), the effect being that, after the turnlocks 3 are correctly engaged, on lifting the container if it is not balanced the frame is tilted and a mercury or gravity switch (38) actuated causing the nuts 7 at the high end of the frame to rotate to increase the effective length of the ropes 5 at that end until the container is substantially level. The normal effective length of the ropes 5 is regained automatically when the container is disengaged and the frame lifted. The self-levelling effect may be switched out of the circuit and the level adjusted if required by the loading conditions (such as a ship trimmed by say 10 degrees by the stem). In a modification (not shown) the screw-andnut devices may be replaced by hydraulic piston-and-cylinder devices, the levelling being performed without power by operating appropriate bleed valves.
