Abstract: 1312810 Motor vehicle drive means MASCHINENFABRIK FAHR AG 17 Nov 1970 [24 Nov 1969] 54667/70 Addition to 1267004 Heading B7H In agricultural machine drive means comprising as described in the main patent a hollow shaft 11 connected to an engine flywheel 1 by a flange 5 and carrying a bevel gear 18 providing a permanently connected drive to a shaft 20, and an auxiliary drive shaft 25 connectible by a toothed coupling to a coupling shaft 8 which is mounted inside the hollow shaft 11 and driven from the flywheel 1 through a friction clutch 2, the toothed coupling is arranged to allow the auxiliary shaft 25 to overrun the coupling shaft 8. A driven element 30, Fig. 2, slidably splined to the shaft 25 has obliquely-sloped teeth 31 engageable with corresponding teeth 32 on a driving element secured to the shaft 8. A spring 29 is interposed between the driven element 30 and a sleeve member 28 slidably mounted on the shaft 25 and having two grooves engageable by a spring-loaded detent ball 39.

Abstract: 1,222,938. Picking fruit, e.g. grapes. A. FONTAN and R. BENAC. 11 Nov., 1969 [12 Nov., 1968; 21 Oct., 1969], No. 55184/69. Heading A1F. Grapes are picked from a row of vines by reciprocating frames 4 carrying assemblies 1 and 2 of parallel fingers 3 horizontally (or vertically) to strike the grapes from the vines, the fingers 3 being resiliently mounted on the frame so as to move easily relative to the frame on striking an obstacle, e.g. the vine stock, so as to prevent or reduce damage to the finger 3 (and to the stock). The finger assemblies 1 and 2 pass one along each side of the vine row 10 and are staggered longitudinally (Fig. 2) or vertically (not shown), the picking machine being suspended from a row-straddling tractor. Each finger 3 projects rearwards of its frame 4 and has its rear end connected by an elastic wire or spring to the frame, each finger 3 being received in a sleeve elastically mounted on the frame; alternatively, each finger 3 projects forwardly from a resilient collar on its frame 4 and comprises a cylindrical rod of resilient material. The finger 3 may have resilient tips. The detached grapes fall into a divided receptacle 8 having elastic skirts 23 and air nozzles 25, the picking machine being centered by shoes 24. Each frame 4 may be horizontally divided into three sections, the upper and lower sections being reciprocated in phase with each other but out of phase with the centre section which has twice the area of each of the upper and lower sections. Each section is reciprocated on its own rails by two double-acting hydraulic jacks which are interconnected with the jacks of the other sections and controlled by slide or solenoid valves. The fingers 3 when fully retracted have their front ends behind a grid 34 of horizontal bars, so that any stems entrained by the fingers 3 are released. A resilient lining 33 overcomes the inertia of the fingers as they start to move forwards.

The transistors are formed on one face of a semi-conductor substrate along which is propagated an elastic surface wave. The output electrodes of the transistors are connected in parallel to a read-out device, so that as the wave progresses across the transistors, representations of the sensor outputs are successively displayed. As shown, FET's 31-34 are formed on an N- type silicon substrate 1 by diffusion of adjacent P-type zones 311, 313 &c. surmounted by an insulating silica layer carrying a gate electrode 312-342 which is connected to a sensor array 4. A surface wave is produced by a transducer 2 responsive to high-frequency pulses from a source 6, such that when a pulse reaches a given transistor a signal is transmitted from the corresponding sensor to a display screen 5. The signals on the screen are displaced in time due to the screen are displaced in time due to the delay produced by propagation of the surface wave. The sensors 4 may be of the piezoelectric type, responsive to a sound image, or photodiodes responsive to an optical image. The substrate 1 may alternatively be a piezoelectric quartz crystal. The transducer 2 may be a piezoelectric prism coupled to the substrate through a glycerol or epoxy resin layer.

In a continuous casting machine, in which the mould comprises at least two movable steel bands 1 (forming opposing walls of a casting) supported by rollers 5, 6, the bands are cooled by a fluid directly contacting the band 1 in a chamber 14 formed by a plate 15, 15a and side seals (40) of polytetrafluoroethylene rubber. A curved fluid inlet nozzle 16, and a similar outlet nozzle 16 ensure a downward water flow which is non-turbulent. The rollers are grooved to lessen friction between themselves and the bands. The upper rollers 5 are water-cooled. In a preferred embodiment four bands form a tapered square sectioned mould cavity 4 the size of which can be adjusted (see Fig. 1). When casting steel the coolant pressure is maintained high enough to prevent the ferrostatic pressure of the steel distorting the casting produced at the lower part of the mould.
